Using illustrative examples, examine why competition authorities might Essay

Using illustrative examples, examine why competition authorities might be concerned about the way large companies behave - Essay Example It has been evident that many large firms indulge in unfair competition to gain advantage over their competitors by unfair means (Hewitt, Clark and Phillips, 2009); therefore competition authorities across the world are concerned about their behaviour. Firms grow so large that unilaterally they harm competition through monopolising the market and take advantage of their size to block threats arising from potential or existing competitors (Hewitt, Clark and Phillips, 2009). For example Microsoft the world’s largest software company indulge in similar such practices that denied other software companies an opportunity to build and market products competing with Microsoft’s products by building licensing agreements that were restrictive, exclusionary and unreasonable and thus monopolizing the client operating- system market by anti- competitive strategies (Justice, 1994 and Bloomberg, 2012). Large companies often make vertical or horizontal agreements with other firms called as cartel to fix prices not considering the reaction of either of its rivals or customers. Dominant firms fix higher price knowing that their customers have few alternatives and little choice other than accepting the firm’s offered higher price (The Competition authority (a), 2013). For example Automobile giant Daimler Mercedes-Benz found guilty of fixing prices in collaboration with five of its van and truck dealers, also shared sensitive commercial information and to some extent market sharing that negatively affected the competition in UK market however they were fined by UK’s antitrust authority of about  £2.6 Million (Reed, 2012 and Binham, 2013). Apart from fixing prices they also control markets or production or make agreements to share markets or supply sources so that rivals supply sources gets restricted. When doing business with other trading parties they put different

Judaism Essay Example | Topics and Well Written Essays - 1250 words

Judaism - Essay Example Judaism's â€Å"Talmud† further explores and explains the religion's teachings, principles, and ethics. According to history, Judaism started with the Covenant between the patriarch, God, and progenitor, Abraham, of the Jews (Abrahams, 2008). The religion is still in practice today and has influenced other world religions like Islam and Christianity. Unlike the other religions in the contemporary world, the central authority in Judaism does not lie in the hands of single individual or group rather in holy writings, traditions, and learned Rabbis who give meaning to those writings and laws of the religion. Judaism has existed for thousands of years already but it remains loyal and true to most of its religious principles (Abrahams, 2008). Among its principles, the most important is the belief in one, omniscient, all powerful, kind, encompassing God, who made the universe and continues to oversees it. The traditional Jewish faith states that the God who made the universe created a covenant with the Israelites, and disclosed his laws and teachings to Moses on Mount Sinai in both the Written and Oral Torah forms, and the Jews are the progenies of the Israelites. It is the study and the observance of God's laws and teachings, as indicated in the Torah and further explained in the Talmud, that the traditional practice of Judaism revolves (Abrahams, 2008). As mentioned, the most important teaching of Judaism is the principle of Monotheism, or Unity of God that serves as the foundation of the religion. The Jews' faith in their one God is more than just being part of their religion. It is a passion and an inspiration that gives them the power and strength to endure tribulations and death. Many people believe that woman are discriminated against in the religious practice of Judaism when Judaism points out that God has both masculine and feminine qualities. It is also said that both man and woman are created in the image of God. This misunderstanding of inequality in men and women is interpreted by the higher power of men up until this very century (BBC, 2012). Most religions commemorate, or celebrate, with certain traditions. As for the Jewish traditions, they have a collection of ritual objects. First is the Yarmulke. This is a small cap that reminds the Jews that they must always live by the words of God at all times and in all places. Next there is the Tefillin. This object is a small leather box that has straps attached that are worn on the left forearm and on the forehead. The inside of these boxes contain scriptures, including the Shema which are little prayers written in the Jewish language. Finally, the last traditional wear is the Tallit. The Tallit is a prayer shawl with fringes that remind them of the commandments of the Torah. They put it on before prayer and worship. Another tradition, and a less amusing ritual, is the Brit Milah. To us, that is a Circumcision. Every baby boy on exactly their eighth day of life is circumcised. T hey also have traditions known as, Bar Mitzvahs for boys, or Bat Mitzvahs for girls. There is also the Baby-naming Ceremony. This tradition is slightly different today, in which many families chose to do this in their own homes, rather then in the Synagogue. A lot of holidays are celebrated with Judaism and they are not the average holidays. One such holiday is called the Passover. This is simply a celebration of the Jewish nation. On this holiday, that takes place on the fifteenth day of the Hebrew month, a Passover Seder is performed. This is where the Jews tell the story of Exodus while they endeavor to transition their life condition from slavery to emancipation. The

Biomedical instrumentation and measurement

Biomedical instrumentation and measurement INTRODUCTION: SA node controls the rate of hearts muscular contractions which enables the heart to circulate the blood throughout the body according to the need. Small variations in the heart beat are not harmful but in some cases due to malfunctioning of the hearts electrical system, the heart rate varies drastically resulting in different types of arrhythmias. These cardiac arrhythmias are serious disorders which should be treated immediately. Arrhythmias like bradycardia (low heart rate) can be treated using Pacemakers. Pacemakers can be implanted in the patients heart for permanently stimulating the heart. It is used for patients for whom the SA node is no longer functioning properly. External Pacemakers are also available which is used to treat temporary heart rate variations. It is used for a short period of time before the implanting the Internal Pacemakers in the heart. In order to understand the requirement of pacemakers, it is necessary to understand the functioning of the heart and its electrical system. HEART ITS ELECTRICAL SYSTEM: Heart is a pumping device which is used to circulate the blood throughout the body. It has four chambers namely Right Atrium, Left Atrium, Right Ventricle and Left Ventricle. The right atrium receives the deoxygenated blood from the entire body through the superior vena cava and inferior vena cava. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. When the atrium contracts the blood flows to the corresponding ventricle. This is due to atrial depolarization. When the left ventricle contracts, the oxygenated blood is supplied to all tissues in the body through the aorta. This is due to ventricular depolarization. Similarly, the deoxygenated blood is pumped to the lungs for oxygenation through the pulmonary artery during the contraction of right ventricle. This is due to ventricular repolarization. The Electrical conduction system of the heart consists of SA node, AV node, Bundle of His, Purkinje Fibers. The chambers of the heart should be stimulated electrically for contraction. The stimulations are provided by the SA node (Natural Pacemaker of the heart) which is located in the right atrium of the heart near the entrance of the superior vena cava. Although all the heart cells have the ability to produce electrical pulses which can stimulate the heart, SA node triggers the heart. The fact that SA node produces pulses at a higher rate when compared to other potential cells which can stimulate contraction, contributes to this phenomena. The contraction of various chambers of the heart is characterized in a very specific manner. As the electric pulses pass through each chamber of the heart, they are stimulated to contract. The SA node first triggers the right and left atrium to contract. Then the impulses travel to the AV node which is located between the atria and the ventricles . From AV node ,the pulses travel to the bundle of his. The pulses travel to the individual ventricles through the right and left bundle branch and reach the Purkinje fibers. If the SA node fails, then the AV node acts as the primary pacemaker. If the AV node fails, then the Purkinje fibers takes the responsibility. The SA node receives blood supply from right and left coronary arteries. Under ischaemic conditions, the death of the affected cells will stop the SA node from triggering the heart beat. There is a period of time following the stimulation of heart muscle during which no other action potential can trigger the heart muscles. This period is known as Absolute or Effective Refractory Period (ERP) of heart. It is normally around 0.4 sec. ERP is maintained as high as possible in order to maintain tachycardia and to coordinate the muscle contraction. The anti-arrhythmic drugs taken by the patients usually prolongs the ERP. ELECTRICAL SYSTEM OF HEART ECG ITS SIGNIFICANCE: The electrical activity of the heart muscles is recorded as Electrocardiogram (ECG). It can be acquired non-invasively from the surface of the body by following specific lead configurations. The electrical current generated in the heart due to depolarization and repolarization is spread not only within the heart but also throughout the body. So, ECG can be easily acquired from the surface of the body through electrodes. ECG has four basic components namely, P wave, QRS complex, T wave and U wave. P wave occurs during atrial contraction due to atrial depolarization. The duration of the P wave ranges from 0.08- 0.1 sec. During the atrial depolarization, the impulse from the SA node spreads throughout the atrium. The time period between the onset of the P wave and the beginning of the QRS complex is about 0.12- 0.2 sec. During the zero potential period between the P wave and QRS complex, the impulse travels within the AV node and the Bundle of His.QRS complex occurs during ventricular c ontraction due to ventricular depolarization. The duration of the QRS complex ranges from 0.06-0.1 sec. T wave occurs during ventricular relaxation due to ventricular repolarization. Sometimes, a small positive U wave occurs following the T wave due to the last remnants of the ventricular repolarization. ELECTROCARDIOGAM NORMAL AND ABNORMAL ECG WAVES: Normal ECG: NORMAL ECG Heart rateis nothing but the number ofheartbeatsper unit oftimewhich is expressed as beats per minute (bpm) which can vary as the bodys need for oxygen changes, such as duringexercise or sleep. The measurement of heart rate is used bymedical professionalsto assist in thediagnosisand tracking of medical conditions. It is also used by individuals, such asathletes, who are interested in monitoring their heart rate to gain maximum efficiency from their training. TheR waveto R wave interval(RR interval) is the inverse of the heart rate ,that is one divided by RR interval gives the heart rate. Typical healthy resting heart rate in adults is 60-80 bpm which is referred to be normal heart rate,with rates below 60 bpm referred to asbradycardia and rates above 100 bpm referred to astachycardia. Missed ECG: MISSED ECG This can be detected when the R-R interval is twice the actual R-R interval (for normal subjects).Heart pulses misses at some intervals and does not follow the premature heart beat. Bradychardia: BRADYCARDIA This is a critical reduction of heart rate and characterized by normally directed abnormally wide P waves and normal PR interval. Whenever the R-R interval exceeds 1 sec the heart rate goes below 60 and the condition is referred to as Bradychardia. There are three types of Bradychardia conditions based on the characteristics of the ECG wave, they are Sinus bradychardia, Atrio-ventricular nodal bradychardia and ventricular bradychardia respectively. They are discussed below. Sinus bradycardia: SINUS BRADYCARDIA Sinus bradycardias are also called as Atrial bradychardias. This bradychardia condition is usually found in young and healthy adults. The symptoms represent with the individualsrespirations. Theabnormalpattern of eachinhalationcorresponds with the heart rate decreasing.Expirationcauses an increase in the hearts rate of contraction. This is thought to be caused by changes in the vagal tone duringrespiration. Sinus bradycardia is a sinus rhythm of less than 60 bpm. It is a common condition found in both healthy individuals and those who are considered wellconditioned athletes. The reason for this is that their heart muscle has become conditioned to have a higher stroke volume and therefore requires fewer contractions to circulate the same volume of blood. Sick sinus syndromecovers conditions that include severe sinus bradycardia, sinoatrial block, sinus arrest, and bradycardi-tachycardia syndrome (atrial fibrillation, flutter, and paroxysmal supraventricular tachycardia). Atrio ventricular nodal bradycardia: ATRIO VENTRICULAR NODAL BRADYCARDIA An atrio ventricular nodal bradycardia or AV junction rhythm is usually caused by the absence of the electrical impulse from thesinus node. This usually appear on anEKGwith a normal QRS complexaccompanied with an inverted P wave either before, during, or after the QRS complex. An AV junctional escape is a delayed heartbeat originating from anectopicfocus somewhere in theAV junction. It occurs when the rate ofdepolarizationof the SA node falls below the rate of the AV node.This dysrhythmia also may occur when the electrical impulses from the SA node fail to reach the AV node because of SA or AV block.This is a protective mechanism for the heart, to compensate for a SA node that is no longer handling the pace making activity, and is one of a series of backup sites that can take over pacemaker function when the SA node fails to do so. This would present with a longerPR interval. A junctional escape complex is a normal response that may result from excessive vagal tone on the SA node. Pathological causes include sinus bradycardia, sinus arrest, sinus exit block, or AV block. Ventricular bradycardia: VENTRICULAR BRADYCARDIA This picture shows an ECG of a person with an abnormal rhythm (arrhythmia) called an atrioventricular (AV) block. P waves show that the top of the heart received electrical activity. Each P wave is usually followed by the tall (QRS) waves. QRS waves reflect the electrical activity that causes the heart to contract. When a P wave is present and not followed by a QRS wave (and heart contraction), there is an atrioventricular block, and a very slow pulse (bradycardia). PACEMAKER AND ITS SIGNIFICANCE: More than 60% people fall victim to heart attacks in most of the countries around the globe every year and thousands more are critically injured in accidents. Taking care of these patients in special care units involves the usage of specialized equipments like pacemakers along the other important ones. In the past few years electronic pacemaker systems have become the important one in saving lives of cardiac patients whose normal pacing functions have been impaired. Depending on the exact nature of a cardiac dysfunction, a patient may require temporary artificial pacing during the course of treatment or permanent pacing in order to lead an active, productive life after treatment. A device capable of generating artificial pacing impulses and delivering them to the heart is known as a pacemaker system (commonly called a pacemaker) and consists of a pulse generator and appropriate electrodes. Pacemakers are available in a variety of forms. They are mainly divided into two types External pacemakers and Internal pacemakers respectively. EXTERNAL PACEMAKER: External pacemakers are used on the patients with temporary heart irregularities, such as those encountered in the coronary patient, including heart blocks. They are also used for temporary management of certain arrhythmias that occur in the patients during critical postoperative periods and in the patients during cardiac surgery, especially if the surgery involves the values or septum. An external pacemaker usually consists of an externally worn pulse generator connected to electrodes located on or within the myocardium. External pacemakers, which include all types of pulse generators located outside the body, are normally connected through wires introduced into the right ventricle via a catheter catheter. The pulse generator may be strapped to the lower arm of a patient who is confined to bed, or worn at the midsection of an ambulatory patient. We have made the pacemaker which can be divided into two general categories namely Asynchronous pacemaker Synchronous pacemaker ASYNCHRONOUS PACEMAKER: This type of pacemaker is intended for patients having permanent heart blocks. The rate is preset. It can be varied externally within the range of 60 PPM to 180 PPM. Since this pacemaker functions regardless of the patients natural heart rhythm it poses a potential danger because of competition between the patients rhythm and that of the pacemaker. PACING PULSES FROM ASYNCHRONOUS PACEMAKER SYNCHRONOUS PACEMAKER: In patients who have normal heart function most of the time, asynchronous pacing can be extremely dangerous, working against their own physiological pacemaker with the danger of stimulating in the vulnerable period of the T wave, a condition that can result in fibrillation. The demand pacemaker consists of an ECG amplifier and a conventional pacemaker output pulse circuit that has been modified to allow output from the ECG amplifier to inhibit the pulse generator. This pacemaker senses R-waves and its timing and logic circuits count out an elapsed time interval following an R-wave or previously induced pulse. If the intrinsic R-wave does not appear before the elapsed time interval, the ventricle is stimulated. If an R-wave is received, the counter is reset again. This type of pacemaker is used for patients with bradycardia, and it ensures a heartbeat no slower than its set rate. PACING PULSES FROM SYNCHRONOUS PACEMAKER INTERNAL PACEMAKER: Internal pacemaker are implanted within the pulse generator placed in a surgically formed pocket below the right or left clavicle, in the left subcostal area, or in women, beneath the left or right major pectoralis muscle. Internal leads connect to electrodes that directly contact the inside of the right ventricle or the surface of the myocardium. The exact location of the pulse generator depends primarily on the type of the electrode used, he nature of the cardiac dysfunction, and the method (mode) of pacing that may be prescribed .Since there are no external connections for applying power, the pulse generator must be completely self contained, with a power source capable of continuously operating the unit for a period of years. BIO POTENTIAL ELECTRODES: A wide variety of electrodes can be used to measure bio electric events but nearly all can be classified as belonging to one of three basic types; Micro electrodes Skin surface electrodes Needle electrodes All three types of bio potential electrodes have the metal-electrolyte interface. In each case, an electrode potential is developed across the interface, proportional to the exchange of ions to the metal and the electrolytes of the body. MICROELECTRODES: They are used to measure bio electric potentials near or within a single cell.Microelectrodes are electrodes with tips sufficiently small to penetrate a single cell in order to obtain readings from within the cell. The tip must be small enough to permit penetration without damaging the cell. This action is usually complicated by the difficulty of accurately positioning an electrode with respect to a cell. Because of their small surface area, they have impedances well up into the megohms. For this reason, amplifiers with extremely high impedances are required to avoid loading the circuit and to minimize the effects of small changes in interface impedance. SKIN SURFACE ELECTRODES: Skin surface electrodes are used to obtain bio electric potentials from the surface of the body. They are available in various size. Although any type of surface electrode can be used to sense ECG, EMG, EEG potentials, the larger electrodes are usually associated with ECG, since localization of the measurement is not important. Smaller electrodes are used in EEG and EMG measurements. Various types of disposable electrodes have been introduced in recent years to eliminate the requirement for cleaning and care after each use. In general, disposable electrodes are of the floating type with simple snap connectors by which the leads, which are reusable, are attached. Although, some disposable electrodes can be reused several times, their cost is usually low enough that cleaning for reuse is not warranted. They come pre gelled, ready for immediate use. NEEDLE ELECTRODES: To reduce interface impedance and, consequently, movement artifacts, some electroencephalographers use small subdermal needles to penetrate the scalp for EEG measurements. They are also used to measure EMG potentials from a specific group of muscles. They are less susceptible to movement artifacts when compared with surface electrodes as they create an interface beneath the surface of the skin. By making direct contact with the subdermal tissue or the intercellular fluids, these electrodes also seem to have lower impedances than surface electrodes of comparable interface area. Even though needle electrodes have less motion artifacts ,surface electrodes are used to acquire ECG because surface electrodes are more convenient for the patient .Most of the surface electrodes are cheap and reusable. ACQUISITION OF ECG USING 3 LEAD SYSTEM LEAD I CONFIGURATION: ECG sensors measure the time-varying magnitude of electric fields emanating from the heart. ECG values are measured by placing non-invasive electrodes at the surface of the patients skin. For a 3-lead ECG sensor, the electrodes need to be placed in a triangle (Einthoven Triangle) on the patients chest as shown in the figure 11. Each corner of the triangle corresponds to one of the limbs: right hand, left hand, left foot. With the bipolar system, one limb is connected to the positive terminal of the amplifier and another limb to its negative terminal. Three limbs (right arm-RA, left arm-LA and left leg/foot-LL) are used. The right leg was used as earth, to minimize interference. ECG AMPLIFIER: Bioelectric signals have very high input impedance. To stop the signal attenuation, we use Instrumentation Amplifier (AD 624) which also has high input impedance. It should have high gain and low output impedance .In order to remove the common mode signals ,it should have a high Common Mode Rejection Ratio (CMRR of about 90 dB).The potential at the surface of the body ranges from 0 10 mV so the amplifier should have high gain (1000). We use a differential amplifier to amplify the bioelectric signals that occur as a potential difference between two electrodes, the bioelectric signals are applied between the inverting and non-inverting inputs of the amplifier. The signal is therefore amplified by the differential gain of the amplifier. For the interference signal, however, both inputs appear as though they were connected together to a common input source. Thus, the common mode interference signal is amplified only by the much smaller common mode gain. The electrode impedances form a v oltage divider with the input impedance of the differential amplifier. If the electrode impedances are not identical, the interference signals at the inverting and non-inverting inputs of the differential amplifier may be different, and the desired degree of cancellation does not take place. Because, the electrode impedances can never be made exactly equal, the high common mode rejection ratio of a differential amplifier can only be realized if the amplifier has an input impedance much higher than the impedance of the electrodes to which it is connected. There are different lead configurations such as 3-Lead, 5-Lead, 12-Lead for acquiring ECG Signal. We have used 3-Lead system Lead I Configuration. 12-CIRCUIT FOR ECG AMPLIFIER AMPLIFIER OUTPUT SOFTWARE IMPLEMENTATION USING LABVIEW: LabVIEW (short for Laboratory Virtual Instrumentation Engineering Workbench) is a platform and development environment for Visual Programming Language from National Instruments. LabVIEW is a graphical programming environment used by millions of engineers and scientists to develop sophisticated measurement, test, and control systems using intuitive graphical icons and wires that resemble a flowchart. LabVIEW offers unrivaled integration with thousands of hardware devices and provides hundreds of built-in libraries for advanced analysis and data visualization. The LabVIEW platform is scalable across multiple targets and operating systems. LABVIEW is a GUI (Graphical User Interface) which can be used for processing of signals, images and other forms of data. One of the most powerful features LabVIEW offers engineers and scientists is its graphical programming environment. With LabVIEW, one can design custom virtual instruments by creating a graphical user interface on the computer screen through which one can: Operate the instrumentation program Control selected hardware Analyze acquired data Display results One can customize front panels with knobs, buttons, dials, and graphs to emulate control panels of traditional instruments, create custom test panels, or visually represent the control and operation of processes. The similarity between standard flow charts and graphical programs shortens the learning curve associated with traditional, text-based languages. The behavior of the virtual instruments can be determined by connecting icons together to create block diagrams, which are natural design notations for scientists and engineers. With graphical programming, one can develop systems more rapidly than with conventional programming languages, while retaining the power and flexibility needed to create a variety of applications. We have used Lab view to acquire the signal, filtering and do other processing of the ECG signal. The real time signal is given into as input to ELVIS I which acts as the DAQ (data acquisition system).The block diagram of the Lab view implementation is as shown in figure 14. STEPS INVOLVED IN LABVIEW IMPLEMENTATION: The ECG signal from the amplifier (using AD 624) is given as input to DAQ for acquiring the signal in Lab view software. FFT of the ECG signal is obtained and viewed. We can see the frequency content of the ECG signal from the FFT obtained. WE can also see the presence of 50 Hz power line interference in the FFT of raw ECG. A Smoothing filter with following specifications Moving average, Rectangular filter with a half width of 20 is constructed. The Smoothened ECG is viewed. Smoothing Filter is used to remove noise and 50 Hz power line interference. The Smoothened signal is given as input to the Butterworth Band Pass Filter of order 2 and a low cutoff frequency of 5Hz and high cut off frequency of 15Hz.Band Pass Filter is used to separate the QRS complex from the ECG Signal. The output of the Band Pass Filter is differentiated and squared inorder to enhance the QRS complex from the remaining portion of the waveform. The heart rate is calculated using timing and tone measurement block. The block gives the frequency of repetition of the QRS complex. The frequency value is converted into time value by taking inverse of it. Heart rate is calculated as follows. Heart Rate = 60/R-R Interval Example: R-R Interval = 760ms Heart Rate = 60/760ms = 78.94 Beats /Minute If the calculated heart rate is below the normal value, then pacing pulses are produced .This is done by using a case structure. The case structure turns on only when the case is true (Heart Rate is below normal value).Inside the case structure we have a square wave generator. The output of the square wave generator is differentiated and squared. We get a pulse as a result of these operations. The rate and amplitude at which the pulses are produced can be modified easily at run time using controls. Whenever the heart rate is normal, False condition is selected . For false condition, we set the amplitude and frequency of the square wave as zero so that the pacemaker is switched off. The Pacing Pulses generated can also be taken out as an analog voltage from the ELVIS and can be viewed in a DSO. Only voltages in the range +10 volts to -10 volts can be taken out from LABVIEW through ELVIS. PACEMAKER FINAL BLOCK DIAGARM. FRONT PANEL IN LABVIEW ENTIRE SOFTWARE IMPLEMENTATTION We have implemented the case structure and other blocks by studying the general tutorials given in LV BASICS 1 MANUAL and LABVIEWBASICSII_85_ENG CLAD. HARDWARE IMPLEMENTATION: BLOCK DIAGRAM FOR HARDWARE IMPLEMENTATTION BAND PASS FILTER: The amplifier which is used in software implementation (AD 624) is also used here. It is followed by a filter. The amplifier output is around 550 mV. A Filter is a circuit that is defined to pass a specified band of frequencies while attenuating all signals outside this band. Filter networks may be either active or passive. Passive filter networks contain only resistors, inductors and capacitors. Active filters employ transistors or op amps plus resistors, inductors and capacitors. Inductors are often used in active filters, because they are bulky and costly and may have large internal resistive components. Band Pass Filters pass only a band of frequencies while attenuating all frequencies outside the band. A simple high pass filter followed by a low pass filter will form a band pass filter. We have used a band pass filter (0.5Hz 40 Hz) to remove high frequency signals like EMG and low frequency components like Base Line Wandering and motion artifacts. We have used a second order Bu tterworth Filter with -40 db/decade roll-off. For Low Pass Filter, we used 0.5 Hz as the cut off frequency.C1 is chosen as a convenient value between 100 pF and 0.1Â µF.For High Pass Filter, we used 40 Hz as the cut off frequency. We have implemented a Band Pass Filter according to the design given in OPERATIONAL AMPLIFIERS AND LINEAR INTEGRATIONAL CIRCUITS. CIRCUIT AND DESIGN FOR BAND PASS FILTER NOTCH FILTER: A Notch Filter transmits frequencies in the pass band and rejects undesired frequencies in the stop band. In applications where low level signals must be amplified, there may be present one or more of an assortment of unwanted noise signals. Examples are 50, 60 0r 400 Hz frequencies from power lines, 120 Hz ripple from full wave rectifiers, or even higher frequencies from regulated switching type power supplies or clock oscillators. If both signals and signal frequency noise component are passed through a notch filter, only the desired signals will exit from the filter. The noise frequency is notched out. We have designed a active notch filter (using LM 324) to remove 50 Hz Power Line Interference. The amplitude of the acquired ECG signal is around 1 2 V. We got noise free ECG for real time signal acquisition as shown below. CIRCUITAND DESIGN FOR NOTCH FILTER REAL TIME ECG ACQUISITION QRS DETECTOR: In order to extract the QRS Complex from the ECG signal obtained, we use a band pass filter with center frequency of 17 Hz and band width of 6 Hz. The QRS signal obtained from the band pass filter is rectified for comparing with the threshold voltage generated by the detection circuit. The filtered and rectified ECG is stored on a capacitor. This filtered and rectified ECG is compared with the fraction of this voltage. Whenever a threshold voltage is exceeded, the QRS pulse is detected. After the detection of every QRS pulse, the capacitor recharges to a new threshold value after every pulse. CIRCUIT FOR QRS DETECTION MONOSTABLE MULTIVIBRATOR: Monostable Multivibrator generates a single output pulse in response to an input signal. It is also known as One Shot Multivibrator. The time period of the output pulse depends only on the external components (resistors and capacitors) connected to the op-amp. The duration of the input triggering pulse can be longer or shorter than the expected pulse. The duration of the output pulse is represented by the T. Since T can be changed only by changing the resistors and capacitors ,the one shot multivibrators can be considered as a pulse stretcher. This is because the width of the pulse can be longer than the input pulse. In a stable or standby state, the output of the multivibrator is zero or low-level logic. The output of the multivibrator is forced to go high (ËÅ"Vcc) when an external trigger is given. The output stays zero until the next triggering pulse is given. Then the cycle repeats. The monostable multivibrator has only one stable state. Hence, the name monostable. The QRS detector gives a pulse for QRS detected which is given as an input trigger for a monostable multivibrator. This monostable multivibrator is used to produce a positive pulse (amplitude 5V) of desired pulse width for every input triggering (negative edge triggering) from the QRS detector. We had used 555 Timer as a monostable multivibrator. MULTIVIBRATOR OUTPUT Thus, the analog section of the project gets over with multivibrator. The output of the multivibrator is processed using PIC18F 4550 Microcontroller. It marks the beginning of the controller section. MICROCONTROLLER: PIC is a family of Harvard architecture microcontrollers made by Microchip Technology, derived from the PIC1640 originally developed by General Instruments Microelectronics Division. The name PIC initially referred to Programmable Interface Controller, but shortly thereafter was renamed Programmable Intelligent Computer. PICs are popular with developers and hobbyists alike due to their low cost, wide availability, large user base, extensive collection of application notes, availability of low cost or free development tools, and serial programming (and re-programming with flash memory) capability. Like all Microchip PIC18 devices, PIC18F4550 family are available as both standard and low-voltage devices. Standard devices with Enhanced Flash memory, designated with an F in the part number (such as PIC18F4550),accommodate an operating VDD range of 4.2V to 5.5V.Low-voltage parts, designated by LF (such as PIC18LF4550), function over an extended VDD range of 2.0V to 5.5V. Our project uses a standard PIC 18F4550.Hence this microcontroller uses a flash program memory of 24K bytes .It is a 8-bit microcontroller and so they handle data as 8-bit chunks. PICs have a set of registers that function as general purpose ram. Special purpose control registers for on-chip hardware resources are also mapped into the data space. The addressability of memory varies depending on device series and in PIC 18F4550 external code memory is directly addressable which is an exceptional feature compared to baseline and mid line core devices. PICs have a hardware call stack, which is used to save return addresses. The hardware stack is not software accessible on earlier devices, but this changed with the 18F4550 device. Hardware support for a general purpose parameter stack was lacking in early series, but this greatly improved in the 18F4550, making the this device architecture more friendly to high level language compilers. Core features All of the devices in thePIC18F 455 series family incorporate a range of features that can significantly reduce power consumption during operation. Key items include: Alternate Run Modes: By clocking the controller from the Timer1 source or the internal oscillator block, power consumption during code execution can be reduced by as much as 90%. Multiple Idle Modes: The controller can also run with its CPU core disabled but the peripherals still active. In these states, power consumption can be reduced even further, to as little as 4% of normal operation requirements. On-the-Fly Mode Switching: The power managed modes are invoked by user code during o

What is Sin? Essay -- Adam Eve Religion Sinning God Essays Papers

What is Sin?   Ã‚  Ã‚  Ã‚  Ã‚  Adam and Eve, the two that started it all. These two names will remain as a reminder to us forever because of their actions. Genesis chapter two talks about how man was made perfect; flawless and in God’s favor. These two individuals change how mankind would be from that time on. Sin entered the world and things began to change.   Ã‚  Ã‚  Ã‚  Ã‚  Before Adam and Eve’s decision there was no sin or death, because of their actions we now have to deal with both. This brings up the question of where original sin came from. We know that God cannot create evil, so it did not come from Him. He gave man free will. From this man went against God and therefore created sin. Because of this we know have inherited depravity. We can not have the relationship that God intended us to have. We now must make a choice if we are going to follow Him or not. Since Jesus’ death we can now ask Him to enter us through the Holy Spirit; God just does not walk with us like He did with Adam in the garden.   Ã‚  Ã‚  Ã‚  Ã‚  Sin has been defined as many things by many groups throughout the ages. In the Old Testament it was defined as a failure to hit a mark or an attitude of rebellion. In the New Testament it is defined as failing to conform to a standard or as a condition. However, we must decide for ourselves what it means in our own lives. The Holy Spirit will guide us in our definition. Without being taught right and wrong we still are able to decipher between the two.   Ã‚  Ã‚  Ã‚  Ã‚  The Bible uses sin in...

Forecast

Dear Ms. Jones: In order to obtain the forecast for the fifth year we had to gather and analyze the data of the four previous years in your company. The trend (data behaving with the same frequency over the years) that was found was the following: The beginning months of the year are the ones with higher sales. As the months go by, sales continue decreasing until December, where sales come back up again. Now, let me explain how we were able to arrive to this conclusion. First, we calculated the average demand by adding up all the sales of all four years and dividing them by the number of months (48). Then, we came up with the ratio by dividing the sales of each period by the average demand. The seasonal index is then obtained by getting the average of the same month ratios of all four years. For example, the average of all the 4 January ratios. The seasonal index is an average that can be used to compare an actual observation relative to what it would be if we there were no seasonal variation. We arrive to the seasonal forecast by dividing the sales by the seasonal index. Then we get the trend line by adding the intercept plus the x-variable and multiplying that by each period. The trend forecast is what will show you the regular trend of the years. That is obtained by multiplying the trend line times the seasonal index. Here’s a snapshot of the trend of the what the fifth year would look like: And here is another graph showing the trend of the four previous years: As you can tell, the sales behavior repeats itself throughout the years. This trend seems to be very consistent. However, I must warn you that the p-value (percentage defective) in the summary output is significantly higher than . 06, (it is a. 404056) and this means this forecast is not very reliable. I also calculated the percentage errors; the absolute percentage error (MAPE) is 3. 85%. This error was calculated by dividing the absolute error (which we got by subtracting the trend forecast from the sales and using the absolute value of that), by the sales, and then getting the percentage of all the absolute percentage errors. I hope this helps you understand the trend of your sales throughout a year. The most important thing for you to identify is the months where you are having higher sales the possible reasons why those sales decrease as the years comes to an end.

Napoleon Bonaparte DBQ Essay

The ideals of the French Revolution were â€Å"Equality, Liberty, and Fraternity,† but the methods that were used to fulfill these goals were complicated. During the Reign of Terror, about 40,000 people were guillotined because of Maximilien Robespierre. He thought that “Liberty could not be secured unless criminals lose their heads”. Napoleon Bonaparte, a Revolutionary hero, seized control of the government in France in 1799, he was looking to bring peace to the French people by ending the Revolution. For this to be done, he had to be in complete control like a monarch or a dictator. However, the French people still wanted to have some of the privileges they had during the Revolution. Napoleon Bonaparte stabilized and united French society, yet supported the ideals of French Revolution. Peace came to France with Napoleon’s strong rule. After making himself a consul for life, he re-established the French monarchy, naming himself Emperor Napoleon I in 1804. He centralized French government by appointing new officials, made tax collections more efficient, and created a National Bank. He believed that he was chosen by God to be in power and made others believe it through the Napoleon Catechism. It showed the French people that Napoleon was blessed to get the throne. â€Å"Â…he whom God had raised up under difficult circumstances to re-establish the public worship of the holy religion of our fathers and to be the protector of it† (Document 7). Napoleon brought civil rights back to France through codes and treaties that talk about revolutionary ideals. The Napoleonic Code is an example. It recognized the equality of all citizens before the law, protected property rights, safeguarded employers by outlawing trade unions and strikes, and supported religion. Napoleon also signed the Concordat of 1801 with the Pope to reverse the dechristianization attempts made during the â€Å"Republic of Virtue.† Napoleon was not a religious man, he realized that most people needed to practice their faith. This made the Catholic Church an ally and they retained the power to nominate bishops, in return, the Pope agreed to recognize the accomplishments of the Revolution and to not question the ownership of the land that had been distributed back then. Napoleon wanted to be the emperor of all of Europe. This could be foreseen  in Jacques Louis David’s painting of Napoleon’s Crossing the Alps (Document 4), where he was portrayed with power, strength and an iron fist. He was a short man, but had an extremely large ego. He controlled a strong army and conquered much of Europe. His empire was made up of the Italian and German states, Spain, Western Russia (for a short amount of time), and Switzerland. With all his power, he still did not mistreat the citizens of the newly conquered territories. He abolished feudal rights and the internal trade barriers in Spain with his Imperial Decree at Madrid in 1808. Napoleon’s concern for the inhabitants of Westphalia was expressed in his letter to Jerome Napoleon in 1807: â€Å"I want your subjects to enjoy a higher degree of liberty, equality, and prosperity hitherto unknown to the German people† (Document 7). Napoleon’s monarch rules stabilized and unified French society, as well as supported some of the ideals of the French Revolution but, Napoleon considered himself friendless and Count Mole perceived the thought behind Napoleon’s actions as â€Å"nothing but his own gratification, of magnifying himself and his power without limit and without rest† (Document 2). The middle class, who had fought a bloody revolution to end absolute rulers, tolerate Napoleon’s ways. With Napoleon in charge their ideals and rights were safe, they would accepted more his policies and given up some of their basic civil rights. Napoleon Bonaparte, 1769-1821, http://en.wikipedia.org/wiki/Napoleon_I_of_France(October 2008)

History of the HOlocaust

History of the HOlocaust A History of the Holocaust In the book A History of the Holocaust: From Ideology to Annihilation, Rita Botwinick makes many valid points about the Holocaust. She discusses major themes occurring during the Holocaust period of World War II such as intentionalism vs. functionalism and the role of churches during the war. She supports almost all of her arguments with solid research and sources as well as personal observations. Her points are very well thought out and persuasive. I would like to focus on a few of the main ideas that stuck out to me as I read the book. Did Hitler want a Germany that was free of Jews or was his master plan simply to wipe all Jews off the face of the Earth? It is this question that gives rise to the debate of whether Hitler held an intentionalist or a functionalist ideology. The arguments in favor of intentionalism insist that Hitler's intent, even before the war, was to systematically and effectively annihilate the Jewish population from the world.English: Rows of bodies fill the yard of Lager Nor...On the other side of this argument is Functionalism. This ideology holds that Hitler did not set out to annihilate the Jews but that the ridding of their race arose, not from a previously devised plan, but evolved due to many factors over the course of the war. Botwinick argues that Hitler did want to rid Germany of the Jewish race but, that the systematic killing of every Jew was not his initial plan. Thus, she reluctantly sides with the functionalist argument. She does, however, cite evidence that at times contradicts this viewpoint. One such contradiction occurs with the dying statement of Hitler. In this quote he states that although he had lost the war, he had "at least been victorious in the destruction of the Jews" (p.

Womens roles Essay

Womens roles Essay Womens roles Essay Have you ever wonder what women did during the 19th century? Did they work, or did they just going shopping? I am here to inform you, the reader, about the lives of these women. Jane Addams was born on September 6, 1860 and died on May 21, 1935. She graduated valedictorian of a class of seventeen and for the next 6 years of her life she would be studying about health but had to cut it short because of her own health problems. After getting better, she financed a home with her friend Ellen and began making speeches about the needs of their neighborhood, took care of children, listened to people when they had no one else and nursed the sick. From doing all these good deeds, in 1905, she was appointed Board of Education in Chicago and made Chairman if the school management committee. She also became the first women president of the National Conference of Charities and Corrections. In 1910, she received the first honorary degree ever to be awarded to a woman by Yale University. Addams wa s a very dedicated feminist of philosophy. She believed women should be able to have their voices heard by legislation and thus have the right to vote, but more complete she thought women should generate desires and such for opportunities to realize them. In 1906, she gave lectures at the University of Wisconsin summer session which she she published her next book, Newer Ideals of Peace. She spoke of peace in 1913 at a ceremony celebrating the building of the Peace Palace at The Hague. An American organization called Women’s Peace Party made Addams the head chairman 1915. The press attacked Miss Addams and was removed from the Daughters of the American Revolution, but she found an outlet for her humanitarian urges as an assistant to Herbert Hoover in providing reassurance supplies of food to the women and children of the enemy nations, which is told in her book called Peace and Bread in Time of War written in 1922.

Hard Sales and Hard Sells

Hard Sales and Hard Sells â€Å"Hard Sales† and â€Å"Hard Sells† â€Å"Hard Sales† and â€Å"Hard Sells† By Maeve Maddox Lilach Alkony wonders about the difference between â€Å"hard sales† and â€Å"hard sells.† The noun phrase hard sell is a U.S. coinage dating from the 1950s. It means â€Å"aggressive salesmanship or advertising.† An example is the late night â€Å"infomercial† that keeps pounding the viewer with â€Å"and wait, there’s more!† Hard sell can be used as an adjective and a verb, as well as a noun. The OED hyphenates the word as hard-sell and offers these examples: 1959 Times Lit. Suppl. 13 Nov. 662/3 One does not see any examples..of what is called ‘hard-sell’ advertising. 1961 Economist 14 Jan. 114/2 The need for the ‘hard sell’ is evident. 1963 Guardian 16 Nov. 14/7 It is difficult to hard-sell the honest song the way they do the contemporary counterfeit. The phrase â€Å"hard sales,† on the other hand, can have various interpretations. It can mean simply â€Å"sales transactions that are difficult to achieve,† as in this headline: Making the Hard Sales, Your Career Depends on It Some headline writers, however, confuse hard sales with hard sell: Sales Training Tip 10 Reasons Why Hard Sales Tactics Never Work The wording of the first reason suggests that the headline was probably not written by the author: People hate being sold to: hard sell will bring out the worst in people. When aggressive sales techniques are used this will prompt the prospective buyer to be aggressive as well and act negatively to the sales person. Pretty soon they are ready to argue with you and you know the sale is completely lost. A web search does turn up many examples of hard sales used with the meaning of hard sell. It seems to me that if the intended meaning is â€Å"aggressive selling,† then the established, unambiguous term is to be preferred. Want to improve your English in five minutes a day?

P&G Case Study Example | Topics and Well Written Essays - 750 words

P&G - Case Study Example where the brightest minds have gathered together over the decades to come up with new products that customers would be happy to use on a regular basis, thus providing strength to the bottom line financially. Over ten years ago, P & G realized that market growth was expanding very rapidly, but that there was a slight decline in P & G sales, and innovation projects were only meeting 15 percent in success targets. This presented a challenge that many companies were facing at that time: how to keep up, move forward, and develop a larger range of fresh innovation which would help drive both the top and bottom growth line (Innosight web: Addison web). The P & G research and development (R & D) group consisted of 8,000 internal researchers situated in laboratories across the globe, in 26 facilities, and it was determined that the company had to find a way to make innovation processes, systematic, repeatable and reliable (Innosight web). Solving the Problem of Innovation and Development. It was decided, at this point, to move research and innovation out to the public level, including the customer view as to what they wanted to see on the market that they would purchase (Innosight web). In essence, this was a case of including the public into its hallowed halls of research and development innovation, in order to move beyond the previous insular situation of researchers who were constantly trying to come up with new ideas. Including the public into this new program, called â€Å"Connect & Develop†, opened many doors for the company innovation program, the researchers involved who helped clients/customers to bring dreams and innovative ideas to life, and provided a much larger, ongoing influx of new ideas and products (Addison web). In the Internet age, this has also become a big bonus where researchers and clients can communicate easily over the Internet in any number of ways, thus speeding up the process of in teraction during the development phase of ideas and

My Political Socialisation Essay Example | Topics and Well Written Essays - 1000 words

My Political Socialisation - Essay Example My father reads political news from newspapers and political magazines as well as watching a lot of news and political discussions online. Views were weak but as I have developed the knack for politics and have surrounded myself with political friends including my father, I have found that my views are changing from being weak to strong. I cannot really confess to being that strong but I am not weak either. On the issue of voting, however, I am fairly strong enough in political affairs to change and be sure to make the correct voting decision based on my political analysis of the candidates. I have engaged in a few political activities and one peaceful political demonstration. I am however yet to identify a good political organization to become its member but it is on my agenda and will soon happen. These political activities have been influenced by my friends and my father. The political demonstration was my friends’ idea and influence which my parents did not agree to, howev er on the other political activities, my father has pushed and encouraged me and some even joining me to carry them out. Lucky for me, I have interest in politics even though they did not develop that long ago. What however impeded their quick development was the lack of political interest my mother and older siblings had and I spent a lot of time with them more than with my father because of his work. However, when he reduced his work travels and was home more often, I found my political niche slowly shifting.

Integrated Critique of Richard Dawkins Selfish Gene and Kozol's Savage Essay

Integrated Critique of Richard Dawkins Selfish Gene and Kozol's Savage Inequlites - Essay Example These perceptions are the reason why a lot of people are dying to go to America; to fulfill their American Dream, as it is commonly known. What they don't know that behind this beautiful image of freedom, peace and equality lays a system that is so cruel and selfish that one would reel at just the thought of it. There are many books that are written in the pursuit of enlightening the readers about the negative side behind America's systems. These books are written not to dampen the spirits of the Americans and the aspiring immigrants of America but to show them the picture that America is not a perfect country it may be a haven for some, but there are also some people who may find it otherwise. The book "Savage Inequalities' by Jonathan Kozol is one of the widely read book that talks about the not-so-good-system of America. This paper is aimed at analyzing the contents of the said book, and thereby evaluating the probable cause and effect of this book to its readers. Also, this paper aims to find out whether Kozol's book is able to make an objective point of view regarding America's unfair system. In Jonathan Kozol's book, "Savage Inequalities", Kozol has described the real happenings in the American Public School System. Conducting visits and research in America's public elementary and high schools, Kozol made a shocking discovery: that despite the new age and laws in America about equality in social class and race, discrimination is still happening and it is taking place in the public elementary and high schools; the place where children go to and learn about these stuff. What is more shocking is that it is done blatantly and no one is taking a stand against it. What more, people who can make changes about these things are even choosing not to address the problem and even voting against doing something about it (Kozol, 1991). It is a vicious cycle, really. Children who are educated in public schools that are inferior in quality, both in facilities and in the academic area, would grow up to occupy the lowest strata in the work force . Since they are used to poor conditions, they would be contented to live with the small wages and poor benefits they would be getting from such jobs. They would marry and their children will once again go to such public school. In turn, children of the rich and the middle class go to good public schools - schools that are complete in facilities and have a good faculty and system. These children would be given good education so that when they graduate they will get jobs that are high paying and white collar. And when it is their turn to raise a family, their children will go to the same good public school their parents went to. So you see, the school serves as a capitalist system that requires the reproduction of the division of labor (Bowles, 1972)). The rich and middle class, knowing that these work at their advantage, see no point in improving the system. In fact, they even create policies to maintain their place in the social strata. Inequality in social status is not the only thing that Kozol has discovered in his rounds in these public schools. He has also found out those public schools that house children of color are more inferior in quality. A good example of such school is the public school in East St. Louis. East St. Louis is populated

Strategic Managment Assignment Example | Topics and Well Written Essays - 750 words

Strategic Managment - Assignment Example It involves the mission, vision and objectives of the company and also the policies and plans that are made to achieve these objectives. Strategic management helps the company to decide about allocating resources and plans in different programs and projects (Sadler, 2003). Our question asks us to discuss and analyse the strategic capabilities of HSBC and Oman International Bank during their merger in Oman. While applying a suitable theory from the strategic management context, we have selected the SWOT analysis framework for the given case study and in the following sections we will be discussing about the various strength, weakness, opportunity and threats aspect of these organizations. HSBC has operated in Oman since 1948 and has decided to merge its Oman branch with Oman international bank. Strategic capability and strength of HSBC in the merger can be stated as the opportunity the bank will get to invest $97.4 million additional capital in a key economy like Oman in gulf. As HSBC is present over there for 60 years in Oman thus they have recognized that this merger as a opportunity which will provide them with lots of opportunities in Oman. On the other side, OIB is the fifth largest bank is Oman who had gross assets of $3.2 billion at the end of December. The strength of the merger with HSBC Oman will provide the company with huge additional capital and the 60 years of operating experience of HSBC and the merger will not effect on the listing of OIB on Muscat Securities Market. The weakness of HSBC Oman before the merger is that HSBC has lack of opportunity and the weakness of OIB is that it is in the fifth position in the country and has lack of potential staffs. This merger will create the largest bank in Oman. Question 2 Identification and Critical evaluation of the change management style that I think is appropriate for the new organization Change management can be defined as an approach which is used in transitioning any team, company or any individual to change it in a desired state. It is a systematic approach which deals with the change from both side of a company and individual. Change management has different aspects which includes adapting the change, controlling change and effecting change (Anderson, 2010). From the aspect of this case, I will like to relate it with the view point of Kurt Lewin’s change management style. The theory is also known as the Unfreeze, Change, Freeze or refreezes (Liu, 2011). Unfreezing stage is the most important stage in change management. It indicates that the company should be ready to change. It involves the understanding regarding changes. The first step involves moving a department or individual or entire business organization towards the motivation that change is necessary to survive in this ever changing competitive environment. The second stage refers to the step towards transition. Because change is not event, it is a everyday process. Transition is the internal movement towards the change. It means the company is unfrozen and moving towards a new form. Strong skills and support is necessary in this stage in the form of training and guiding. Same in case of HSBC bank Oman SOAG, new company needs this change strategy to unfreeze itself to proceed

Frank Lyod Wright and Louis Sullivan Essay Example | Topics and Well Written Essays - 1000 words

Frank Lyod Wright and Louis Sullivan - Essay Example Louis Sullivan, one of the great architects of the last half of the 19th century, was a brilliant artist with both practical office experience and a year at the famed cole des Beaux-Arts in Paris before entering a partnership with Dankmar Adler in 1879. Credited with being the first to give an appropriate form to the steel skyscraper, he was a precursor of American modernism and managed to produce the only forward-looking design of the 1893 World's Colombian Exposition in Chicago.1 Unfortunately and unfairly, this designer of dozens of lauded buildings, who helped reshape the manner of building structure and aesthetics, is primarily known today for one thing-his role as Frank Lloyd Wright's Sullivan's famous motto of "form follows function" influenced Wright immensely and was a major reason why Wright considered Sullivan his only influence. That the relationship was mutual is demonstrated by the events of 1889. In that year Wright married Catherine Lee Clark Tobin, and Sullivan loaned him the enormous sum of $5,000 to buy property in Oak Park, Illinois and build a house.4 His willingness to help Wright illustrates the mutual respect between the employer and employee at this time. Although one of his early works, the Frank Lloyd Wright Home and Studio in Oak Park can be considered a workshop, used by the architect to begin developing some intriguing concepts. The initial construction phase of 1889 "exhibits features that portend the mature Wright's philosophy of architecture: the emphasis on pure geometric forms, the broad, sheltering roof, the use of natural materials and the unity of building and site".5 These features blurred the distinctions between inside and outside, and marked a growing integration of landscape and construction. In addition, the interior was focused around the fireplace and astonishingly open in design, with none of the Victorian hierarchy of divided spaces evident. Wright continued designing houses in Oak Park on the side, and this conflict of interest led to Sullivan firing him in 1893.6 Never one to stop working, Wright simply opened his own office and specialized in domestic architecture. By 1902 he designed his first Prairie house, a style defined by horizontal orientation, rows of small windows, low-pitched roofs featuring overhanging eaves and an open interior plan with a central fireplace.7 With its definitive wood and stucco exterior, it also works in conjunction with the suburban setting. Its cruciform plan is designed so that the movement from one wing to the next is diagonal, and these 45 degree angles are featured in other parts of the house.8 This epoch construction, completely distinct from Sullivan's verticality, would not have been possible had he not been fired. Decades of both personal and professional trouble followed, but Wright weathered the strenuous difficulties and re-emerged in the 1950's. His most famous project from this final stage is undoubtedly the Wright, Frank Lloyd, the Solomon R. Guggenheim Museum of 1956-1959. Completed after his death and considered Wright's "great swansong",9 it is an exercise in pushing concrete to the limits of plasticity. After entering the inverted swirl, visitors move to the top via elevators and proceed "downward at a leisurely pace on the gentle slope of a continuous ramp".10 This final monument vividly illustrates how far Wright progressed from the early stages of his career. However, the first Wright building to feature an internal spiral ramp was the V. C. Morris Gift Shop of 1949, designed concurrently to the Guggenheim project.11 Inside are display cases and shelves that follow

Confederation and Constitution Essay Example | Topics and Well Written Essays - 1000 words

Confederation and Constitution - Essay Example The American constitution underwent a lengthy process during its drafting and various amendments have been made so that it can be more efficient for the governing of the states. In 1776, the continental congress drafted â€Å"the article of confederation† which brought together 13 founding states of the United States of America: This article was later ratified in 1781. In the article of confederation, the relationship between the uniting states was defined and also a common name was adopted for the union of the states (Howard, 2005). After various administrative set backs, this article of confederation was found to be inefficient and hence was later replaced by the American constitution in 1789. Though the article of confederation had some similarities with the constitution, these two documents were different in the following ways. The constitution established an organized form of government. The government was divided into three main braches, which included the executive, the judiciary, and the legislature. In the constitution, the executive was the supreme arm of the government and it was headed by the president. The constitution provided the rules and regulations governing election of the president and his deputy. However, in the article of confederation, there was no such structured government. The states had the liberty to decide the method of leadership they wanted. The constitution established a federal system government. In this system, the states had some authority.

Sodium, and Potassium Essay Example for Free

Sodium, and Potassium Essay Discussion In this lab, six different metals were tested for their reactivity in water. From less reactive to most reactive, the metals were as follows: Aluminum, Magnesium, Calcium, Lithium, Sodium, and Potassium. A pattern found in the periodic table explaining the reactivity of metals is the further down in a family, and the further left in a period, the more reactive the metal will be. Aluminum and Magnesium were both the less reactive. Neither of the metals produced hydrogen, or not enough to have a positive test to prove it was there. Metals + H O H + Metal Hydroxide Calcium gave off a large amount of Hydrogen gas. Lighting a splint, placing it in the test tube, and hearing a loud pop proved this. When the calcium was placed in the water, it caused the temperature to rise to such a high level it was not possible to hold with bare hands. This could be because the electrons are moving so quickly that it causes the temperature to rise. The calcium formed a white, powder-like precipitate at the bottom of the test tube. Lithium, Sodium, and Potassium all had very violent reactions in water. Phenolphthalein was added to the beakers after the metals had reacted, and the water turned a pink/ purple color proving that these metals make bases, and therefore have a pH between eight and. Common reactions between metals were they all formed hydrogen gas, even if it was a very small amount. Lithium, Sodium, and Potassium all tested positive to be a base with phenolphthalein, and all had an oily surface. A pattern found in the periodic table explaining the reactivity of metals is the further down in a family, and the further left in a period, the more reactive the metal will be. This is because the elements in period I, Lithium, Sodium, and Potassium, only have one valence electron, and it is quite simple to lose it. Also, the further down the family, the more the ionization energy decreases because of the shielding effect (the inner electrons block the attraction of the nucleus for outer electrons) and atomic radius (the greater the distance between the nucleus and the outer electron). However, the further to the right of the periodic table, the more the ionization energy increase because of the nuclear charge, electron arrangement ( an electron in a full of a half full energy level requires additional energy to be removed), and atomic radius. This explains why Aluminum was the least reactive, and Potassium was the most reactive.

State Bank Of India Marketing Essay

State Bank Of India Marketing Essay The banking industry is highly competitive. The financial services industry has beenaround for hundreds of years and just about everyone who needs banking servicesalready has them.

Are Bull Markets Supported By Rational Growth in Stock Valuations? :: Finance Financial Economics Essays

Introduction â€Å"The rich get richer† is a frequently heard adage in the United States, a country quickly associated with capitalism. US financial markets make headline news on a daily basis, so people are well aware when the domestic stock market’s indices rise or fall.

Tom Sawyer - No Average Young Boy :: The Adventures of Tom Sawyer

The Adventures of Tom Sawyer: No Average Young Boy To say that Tom Sawyer was an average young boy growing up in Illinois would be an understatement. "The Adventures of Tom Sawyer", written by Mark Twain is an absolutely enchanting book. Every episode is more exciting than the prior one, which is why this book receives five stars. Set in the old Southwest in an almost poverty stricken shabby village called St. Petersburg. The whole town knows one another, and of course they know each other’s business. Sunday was the holy day when everyone would gather at the church to compare notes on the past weeks events. The children had to rely on making good clean fun from meager surroundings. Swimming, fishing, picnicking, and playing "Hide n' seek" in the long hot summer days were all good ways to pass the time. But Tom was more venturesome than that, and with his best friend Huckleberry Finn, he lived everyday to its fullest. Tom had a little more schooling than Huck, but Huck was growing up on the streets and surviving just fine considering that his father was a drunk. Tom had a good home, being raised by his Aunt Polly, (his mother died so her sister took him in). He also lived with his half-brother, Sid, whose main objective in life was to make Tom’s miserable by ratting him out all the time, and his q uiet cousin Mary. His antics were ingenious though. The way that he turned whitewashing the fence as a punishment into a grand experience for all of the boys in town who couldn’t wait to hold the brush and paint. Tom was not a bad boy, just an inquisitive one who’s mind never rested†¦ always dreaming, and making his dreams sound so good, he could always rope Huck Finn into his escapades. Tom couldn’t lie, and he couldn’t see someone suffer for the sins of another, as seen when he tells the truth about the murder of Dr. Robinson. It took real guts to point the finger at "Injun Joe", the half-breed, who was also one of the most despicable scoundrels in the town. Tom was also loyal to his friends, and showed that when he wouldn’t tell that Huck Finn was with him that night the doctor was killed in the graveyard. Tom also couldn’t leave Becky Thatcher in the cave when they were lost and she had all but given up hope of being found.

Participant roles and purposes Essay

In talking about social situations and participants, Goffman suggests that situations move forward in accomplishing Ð ° goal or purpose because the participants come to Ð ° â€Å"working consensus† about the nature of the situation: â€Å"Together the participants contribute to Ð ° single overall definition of the situation which involves not so much Ð ° real agreement as to what exists but rather Ð ° real agreement as to whose claims concerning what issues will be temporarily honored† (1959: 9-1o). The working consensus of most teacher-student meetings is realized through the expectations and obligations of the role of teacher and student. These roles have mirroring expectations (the actions others can insist we perform) and obligations (the actions we can insist others perform) (Goffman 1967: 126). For example, the obligations of the student role–to read, to take exams, to attend classes–are expectations of the teacher role. The expectations of the student role–to receive information, to be given fair exams, to be graded on the basis of merit–are the obligations of the professor role. Thus these roles become interdependent; the expectations and obligations are complementary and in service to each other. In their interviews, both the Professor and the Student focus on the expectations and obligations of their respective roles as teacher and student, They both articulated the role of the Student as checking on an assignment (getting information) and making sure the Student had Ð ° clear understanding of the Professor’s expectations (giving information). The Professor: â€Å"My view of the meeting was that І was there to answer [the Student’s] questions, not that І was there to tell him anything. І think that’s why І started the meeting by looking expectantly at him. † The Student explained his purpose: â€Å"My purpose was to make sure І understood the assignment correctly and was going in the right direction. The paper was supposed to be handed in during class, and І held it back because І wanted her to check it first. If she approved, then fine, І would hand it in. І knew the ASL would be hard to understand, so І wanted to ask if І should go ahead with the ASL story or follow the English interpretation. † When asked if they thought the meeting was successful, that expectations and obligations were met, both responded affirmatively. They explain in their own words. The Professor: â€Å"The meeting was successful. Nobody yelled at anybody. [The Student] came to get information and he got it. The laughter, І think the laughter is my signal that everything is going well. І felt [the Student] knew what he was supposed to do. † The Student: â€Å"She read my story and seemed satisfied with it. І knew she wanted me to improve it and bring it back with thirty copies. Yes, the meeting was successful. † Although the Professor comments on the interactional success, â€Å"nobody yelled at anybody† as well, both speakers are attentive to the primary purpose, and their ensuing obligations, of Ð ° teacher-student meeting. As the next chapter demonstrates, many of the Professor’s and the Student’s motivations for speaking or taking Ð ° turn center on their expectations or obligations of their social roles, their roles define their purpose for meeting and constitute how they will interact and how their meanings are represented in talk. The Interpreter’s role is to interpret. In general, the role of an interpreter is to make possible communication between people who do not speak the same language. The Interpreter defined his role, what he says it always is, as working to have effective communication, â€Å"for people to communicate. † However, when asked if he thought the meeting went well, he offered Ð ° perspective that was not centered on whether or not the participants had effective communication: â€Å"Yes, because І think [the Student’s] goals were achieved, in getting some ideas across and talking about some issues. That he understood where she was coming from and she understood where he was coming from† Although this response is vague and unfortunately not further clarified; there are some indications as to what the Interpreter is referring. When the Interpreter mentions â€Å"[the Student’s] goals were achieved,† it appears that the Interpreter assumes goals other than getting an assignment reviewed. He continues by adding â€Å"getting ideas across† and â€Å"talking about some issues,† but the only â€Å"issue† mentioned previously by the Interpreter is connected to people communicating. The Interpreter never mentioned checking the assignment or the Student getting information on how to analyze the narrative, nor did he mention the Professor’s obligations she might have for meeting with students. Because both primary participants are involved with the study of language and because the study of ASL as Ð ° natural language was still Ð ° relatively new idea, many conversations with linguists who study spoken languages come around to the topic of the differences between Ð ° signed language and Ð ° spoken language. At the time, the status of ASL as Ð ° language in the larger world community was not firmly established, nor was the status of Deaf persons as member’s of Ð ° linguistic and ethnic minority. That these â€Å"issues† particularly affect interpreters can be demonstrated by reading newsletters and journals published at the time in the interpreting field, as well as by attendance at meetings and conferences. These debates and discussions are often referred to with phrases such as â€Å"getting ideas across† and â€Å"talking about issues,† so І can suggest the possibility that the interpreter is referring to these potentially explosive arguments about the acceptance of American Sign Language as Ð ° natural language. Fortunately, this is not an issue with the Professor, as the Interpreter acknowledges: â€Å"She’s obviously educated [about Deaf people] in that she’s familiar with deafness and Deaf people because she explained the outgoing message on the answering machine, things that are very hearing culture and so І think that in some regards she took care of all that. † Although he acknowledges that the Professor is familiar with deafness and Deaf people, it is also his focus on her adaptations to the Student that remain primary in his reflection on the interpreted event. The answering machine was Ð ° few seconds of small talk before the more important discussion of the Student’s narrative and transcript. The Interpreter’s focus on â€Å"getting ideas across† and taking care of cultural differences reflects what is Ð ° central concern of interpreters in their role, the notions of equality and justice. It seems that the Interpreter feels that it is incumbent on him in his role to create an understanding and Ð ° balance between these speakers moreover, the Interpreter never commented on the discussion around the assignment for either participant. To see how far the Interpreter’s thinking was from the thinking of the primary participants, here is what the Professor said about the answering machine talk: â€Å"[І was] trying to be polite and make everyone comfortable, telling him about the answering machine and the knocking at the door and then І realized [there was] no reason to tell him. † The Interpreter has attributed the meaning of the talk to the Professor’s awareness of Deaf people when, in fact, she was focused on the nature of starting to talk and the often necessary small talk that is Ð ° prelude to official business. Because interpreters are primarily concerned with communication, of language and also of cultural nuances, much of an interpreter’s concern is for differences in language and culture. But speakers themselves are typically concerned with the central task of the meeting, carrying out their obligations and responsibilities necessary to accomplish their goals. We will see in the next chapter that an interpreter’s role is more than to â€Å"just translate† or â€Å"just interpret. † What the role is and how to manifest that role to others, while appearing neutral or impartial, is not an easy task. If an interpreter’s role expectations and obligations were as easily defined as the teacher or student role, then there would not be the problems, concerns, and issues that arise around the discussions about an interpreter’s role.

Depth first-aid and the branches of it Essay

First Aid, emergency care for a victim of sudden illness or injury until more skillful medical treatment is available. First aid may save a life or improve certain vital signs including pulse, temperature, a patent (unobstructed) airway, and breathing. In minor emergencies, first aid may prevent a victim’s condition from worsening and provide relief from pain. First aid must be administered as quickly as possible. In the case of the critically injured, a few minutes can make the difference between complete recovery and loss of life. The First aid measures depend upon a victim’s needs and the provider’s level of knowledge and skill. Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury, for example, can lead to permanent spinal injury and paralysis. Despite the variety of injuries possible, several principles of first aid apply to all emergencies. The first step is to call for professional medical help. Determine that the scene of the accident is safe before attempting to provide first aid. The victim, if conscious should be reassured that medical aid has been requested, and asked for permission to provide any first aid. Next, assess the scene, asking bystanders or the injured person’s family or friends about details of the injury or illness, any care that may have already been given, and preexisting conditions such as diabetes or heart trouble. The victim should be checked for a medical bracelet or card that describes special medical conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move the victim. First aid requires rapid assessment of victims to determine whether life-threatening conditions exist. One method for evaluating a victim’s condition is known by the acronym ABCs, which stands for: A — Airway–is it open and unobstructed? B — Breathing–is the person breathing? Look, listen, and feel for breathing. C — Circulation–is there a pulse? Is the person bleeding externally? Check skin color and temperature for additional indications of circulation problems. Once obvious injuries have been evaluated, the injured person’s head should be kept in a neutral position in line with the body. If no evidence exists to suggest potential skull or spinal injury, place the injured person in a comfortable position. Positioned on one side, a victim can vomit without choking or obstructing the airway. Before treating specific injuries, protect the victim from shock–a depression of the body’s vital functions that, left untreated, can result in death. Shock occurs when blood pressure (pressure exerted against blood vessel walls) drops and the organs do not receive enough blood, depriving them of oxygen and nutrients. The symptoms of shock are anxiety or restlessness; pale, cool, clammy skin; a weak but rapid pulse; shallow breathing; bluish lips; and nausea. These symptoms may not be apparent immediately, as shock can develop several hours after an accident. To prevent shock, the victim should be covered with blankets or warm clothes to maintain a normal body temperature. The victim’s feet should be elevated. Because of the danger of abdominal injuries, nothing should be administered by mouth. Asphyxiation occurs when air cannot reach the lungs, cutting off the supply of oxygen to circulating blood. This can cause irreparable damage to the brain. Among the causes of asphyxiation are drowning, gas poisoning, overdose of narcotics, electrocution, choking, and strangulation. Victims may collapse, be unable to speak or breathe, and have bluish skin. Most people will suffer brain death within four to six minutes after breathing ceases unless first aid is administered. In the case of choking, a procedure known as the Heimlich maneuver can be used to clear the windpipe of food or other objects. In this procedure quick upward thrusts are applied to the victim’s abdomen to eject the object blocking the windpipe. For victims of other types of asphyxiation, the most practical method of artificial respiration is the mouth-to-mouth technique in which the first-aid provider forcefully exhales air into the victim’s lungs after first clearing the airway of any obstruction. The provider tilts the victim’s head backward by placing one hand under the victim’s chin and lifting while the other hand presses down on the victim’s forehead. At this point, the mouth and airway can be checked for foreign objects, which can be removed with the fingers. In cases of drowning, artificial respiration should be attempted even if the victim appears dead. People submerged in cold water for more than 30 minutes who appeared blue have responded to first-aid efforts and recovered with no brain damage. The presence of blood over a considerable area of a person’s body does not always indicate severe bleeding. The blood may ooze from multiple small wounds or be smeared, giving the appearance of more blood than is actually present. The rate at which blood is lost from a wound depends on the size and kind of blood vessel ruptured. Bright red, spurting blood indicates injury to an artery while welling or steadily flowing, dark red blood indicates injury to a vein. Welling or spurting blood is an unmistakable sign of severe bleeding. If a major artery ruptures, a person may bleed to death within a minute. Injuries to veins and minor arteries bleed more slowly but may also be fatal if left unattended. Shock usually results from loss of fluids, such as blood, and must be prevented as soon as the loss of blood has been stopped. A poisonous substance introduced into the body through the mouth or nose causes symptoms such as nausea, cramps, and vomiting. Poisons include toxic medications, herbicides, insecticides, rodenticides, household disinfectants, and noxious gases. In a case of poisoning, the first-aid provider should remove the victim from a toxic environment, then contact the poison control center listed in most  United States phone books. If the number is unavailable, the provider should call a physician or hospital emergency department. If possible, the provider should try to identify the poison, either by questioning the victim or searching for suspicious containers. Containers of many poisonous substances list the antidote, or remedy, on the label. Burns or stains on the skin or a characteristic odor on the breath may also help the first-aid provider recognize the poison. Unless instructed to do so by the poison control center, the first-aid provider should never give a poisoning victim anything to eat or drink. Vomiting should not be induced unless the poison control center recommends it. If the victim vomits, the first-aid provider should turn the individual on the side and clear the airway. Before clearing the victim’s mouth of any obstructions, however, the provider should first put on clean first-aid gloves or wrap a cloth around his or her fingers. If the person who ingested the poison is unconscious, the airway, breathing, and circulation should be checked and CPR started if necessary.
