The Outsiders By SE Hinton Essays - Films, The Outsiders, Greaser

The Outsiders by SE Hinton In this book analysis, about the book ?The Outsiders? by S. E. Hinton I will discuss character and plot development, as well as the setting, the author's style and my opinions about the book. In this part of the analysis I will give some information about the subjects of the book, and about the author. The author wrote the story when she was just 16 years old, in the 1950s. The book was successful, and it was sold, and still being sold, in many copies as a young adults novel. There was a movie made about it, and today there are still many schools that use this book in junior high and high schools for English classes. There were plays made about the book too. The Outsiders is about a gang. They live in a city in Oklahoma. Ponyboy Curtis, a 14 year old greaser, tells the story. Other characters include Sodapop and Darry, Ponyboy's brothers, Johnny, Dallas, and Two- Bit, that were also gang members and Ponyboy's friends. This story deals with two forms of social classes: the socs, the r ich kids, and the greasers, the poor kids. The socs go around looking for trouble and greasers to beat up, and then the greasers are blamed for it, because they are poor and cannot affect the authorities. I hope you would enjoy and learn something about the book from reading this analysis. Plot Development The plot development in the book, ?The Outsiders? by S.E. Hinton, was easy to follow. In this part of the book analysis I will give some more details about the plot development. There were no hooks or hurdles in the beginning of the book, the first sentence starts right away with the plot?without any forewords. This is the beginning of the first sentence: ?When I stepped out into the bright sunlight from the darkness of the movie house...? (page 9). As you can see, it goes straight to the point without any prologues or any kind of introduction. The plot development in the middle of the story was sensible and easy to understand. It was clear and simple, and the events have occurred in a reasonable order. The ending of the story was a bit expected. I anticipated the death of Johnny because a broken neck usually means death. The death of Dally was not as predictable as Johnny's death because it was said that: ?He was tougher than the rest of us?tougher, colder, meaner.? (page 19). I did not think that such a tough person would get himself killed because of a death of a friend, although it was said a short time before the death of Dally that: ?Johnny was the only thing Dally loved.? (page 160). The climaxes at the end of the story were the deaths of Johnny and Dally. Here are quotations about the deaths: Johnny's death: ?The pillow seemed to sink a little, and Johnny died.? (page 157). Dally's death: ?He was jerked half around by the impact of the bullets, then slowly crumpled with a look of grim triumph on his face. He was dead before he hit the ground.? (page 162). To conclude I can say that the plot development was simple and easy to understand and to follow. The author organized it in a way that fits the actual content of the plot. Character Development The characters in the book, ?The Outsiders? by S.E. Hinton, were not very heroic?they were just humans?it was easy to believe that this is the way they should be. The characters in the plot give the reader a feeling this can be a true story. The author has created the personality of the characters through the descriptions of Ponyboy?the narrator?and through their actions. Following are some examples of these methods of getting familiar with a character. Here is an example for a description of Ponyboy: ?Steve Randle was seventeen, tall and lean, with thick greasy hair he kept combed in complicated swirls. He was cocky, smart, and Soda's best buddy since grade school. Steve's specialty was cars...? (page 17). The reader can find this kind of descriptions almost everywhere in the story, but especially in the beginning. I

Ingenious vs. Ingenuous #2

Ingenious vs. Ingenuous #2 Ingenious vs. Ingenuous #2 Ingenious vs. Ingenuous #2 By Mark Nichol What’s the difference between ingenious and ingenuous, and are they even related? If you believe that despite their seeming disparity in meaning, these words belong to the same genus, you’re a genius and you therefore probably know as well that those terms with the common element gen share their origin with the first pair of words. Ingenious, ingenuous, and several other words and their variations are derived ultimately from the Latin verb gignere, which means â€Å"to produce.† One of that term’s descendants is engine, which traces from ingenium, meaning â€Å"talent.† Originally, engine meant â€Å"trick or device,† but it later came to be applied to machines used in warfare and then to mechanisms in general. Gin, an abbreviation of the French form engin, eventually referred specifically to a device that separates cotton from the cotton plant’s seeds. (The name of the alcoholic beverage gin and that of the card game gin rummy are corruptions of the place name Geneva and are unrelated.) Genus, meaning â€Å"a class or kind,† and general, with the same basic meaning but best known for other connotations and in various forms, are ancient kin of these other words including the element gen. So is genius, which first referred to a guardian spirit but came to apply to innate talent. Two other closely related words are genie, from the French form of genius (which later was associated with the similar-sounding but unrelated Arabic word djinn to refer, in French and later English translations, to a spirit or force in Arabian mythology and folklore) and genial, also descended from genius but now meaning â€Å"friendly,† as well as congenial (â€Å"pleasant, harmonious†). Ingenious developed a sense of â€Å"clever† through its predecessor ingenium. Ingenuous, however, took a different route, evolving in sense from â€Å"high-minded† to â€Å"straightforward† to â€Å"innocent.† The feminine form in French, ingà ©nu, altered in English to ingenue, came to refer to a stage character defined by her artless simplicity. The term was extended to apply to a young, innocent female lead character in live and recorded performances and in literature (and, occasionally, to such a person in general).

OSHA and EPA Coursework Example | Topics and Well Written Essays - 500 words

OSHA and EPA - Coursework Example OSHA was primarily formed to ensure optimal and safe working conditions for the employees through the set-up of standards that provide the necessary training, outreach, education, and assistance. It was also tasked with the enforcement of whistleblower statutes and regulations (Rodrigues and Cusick, 2012). EPA, on the other hand, conducts routine environmental assessments and enforces national standards under different environmental laws. The organization also has powers to fine or sanction institutions whose operations contravene the set environmental statutes. OSHA’s standards apply in the aviation industry with regards to the safety standards. For example, when working on a flight line, the employee is to be provided with protective gear such as safety glasses, steel toe boots, hearing protection equipment and so forth. These requirements are in accordance with the OSHA standards. In addition, OSHA requires that the employees who work in high noise environment be subjected to periodic hearing examinations (Rodrigues and Cusick, 2012). The organization also outlines guidelines to be followed in the identification of methods for handling hazardous chemicals such as hydraulic fluids, jet fuel, battery maintenance and so forth. This standard demands that all employees tasked with maintaining these dangerous chemicals must undergo appropriate training. Moreover, a material safety data sheet that lists all the chemicals on site, their composition, and the precautions to be adhered to should be made available. The Environmental Protection Agency is primarily tasked with the regulating the disposal of hazardous chemicals in the environment. The organizations Resource Conservation and Recovery Act (RCRA) has a direct impact on the aviation industry. The RCRA act requires the airlines to take up the responsibility for the management, control and disposal of the toxic substances related to the industry (Rule, 2011).These materials include

The Life of Christ Research Paper Example | Topics and Well Written Essays - 2250 words

The Life of Christ - Research Paper Example In the verse of evangelist we are not told that the angelic songs were heard by any other group except the shepherd that was grazing that night. The saviors’ ancestress, Ruth was in the same field where the same shepherds were guarding their flock from wild animals, she was sick at heart among the foreign corn (Farrar 1). David, the youngest son of a large family had followed the sheep and suddenly hears of the great news about the Christ Jesus being born amongst the irrelevance of a world lifeless of its liberation there was angel’s assembly of heavenly host praising God and saying Glory to God and there be peace on earth among men of good will. It might have been expected that Christian goodness could protect the rude grotto of shepherds in the minds of the church but instead the chapel of the herald angel is a â€Å"mere rude tomb† (Farrar 2). The poverty of chapel matches well with the humble toil of those whose happy vision is intended to remember. In the te mple, only four of our lords beginning are narrated by gospel, the circumcision, and the presentation in the temple, the visit of magicians and the flight into the Egypt. Fist two occurs in St. Mathew and no single particular can be pointed out in which the two narratives are necessary contradictory. Its only since in the dawn of Christian children are surrounded with romance. The exact order of the eighth day after the birth of (Luke i.59; 21) the purification was thirty-three days after the circumcision (Lev xii 4) The narrative of the visit of magician recorded in the second chapter of St. Mathew is of the deepest interest in the history of Christianity. The facts of the gospel are brought together with Jewish believes. This furnishes us with the new confirmation of our faith. After the wise had offered their gifts they would naturally have returned to Herod but being warned they returned to their own land another way. We don’t find further traces of their existence but th eir visit led to very memorable events (Farrar 5). Physical geographical of Palestine is perhaps more distinctly marked than that of any other country in the world the country character from north to south may be represented by four parallel bands, the Sea-board, the Hill country, the Jordan valley, and the Trans-Jordanian range. The country hill, which thus occupies the space between the low maritime plain and the deep Jordan valley, falls into two great masses, the continuity of the low mountain-range being broken by the plain of Jezreel (Farrar 6). Even as there is one hemisphere of the lunar surface on which, in its entirety, no human eye has ever gazed, while at the same time the moon's freedoms enable us the estimation of its general character and appearance. This is therefore is one large portion of our the Lord's life of which there is no full record; yet such suggestions are, as it were, given to us of its outer edge, and from this, we are able to understand the nature of t he whole. Again, when the moon is in arched, a few bright points are visible through the telescope upon its illuminated part; those bright points are mountain peaks, so lofty that they catch the sunlight. One such point of glory and majesty is revealed to us in the otherwise unknown region of Christ's youthful years, and it is sufficient to provide us with a real vision into that entire portion of His life. In modern language we should call it a story of the Savior's confirmation (Farrar

Conclusions And Future Scope Engineering Essay

Conclusions And Future Scope Engineering Essay In the integrated circuit industry, the ceaseless effort to decrease critical transistor dimensions in each new technology guarantees that the prominence of electrostatic discharge will continue to grow. Devising ways to protect electronic devices against ESD is just as important as determining how to process and manufacture them because a product with susceptibility to damage will not be accepted. As a result of increasing susceptibility of devices to ESD because of miniaturization, the problem of ESD is now being dealt by most IC manufacturers and electronic system designers at several levels, from designing on-chip protection circuits to off chip protection design for systems. Once an IC is packaged and shipped to a customer, however, the in-built, on-chip protection circuit is the only means of defense against ESD damage. At the system level, the on-chip protection may not be sufficient to handle the system level ESD exposure. So off-chip or on-board protection devices are necess ary to protect the system from real world ESD. While circuit designers have successfully created robust ESD protection for past technologies, a lack of understanding of effects of ESD on various devices, circuits and systems; the mechanisms underlying ESD damage makes the susceptibility of electronic components to ESD still a hot topic of research. Mathematical analysis and estimation to calculate the induced transient voltages in shielded and unshielded cables is presented. This enables us to find the induced voltage and its rise time appearing at the terminals of the electrical equipment which are connected to such cables. This enables the designers to design protection circuits at the front-end of the equipment. The effect of ESD on logic gates, analog circuits, digital circuits, microcontrollers and complex electronics are presented. This chapter presents the contributions of this thesis toward implementing a methodology of characterization of the effects of indirect and direct ESD on various electronic components. Also the implementation of the board design and protection circuits on a custom designed microcontroller board based on an understanding of the ESD failure mechanisms of various devices and circuits is presented. This chapter covers the future scope on the research work carried out on ESD. The following results and conclusions have been arrived upon. 8.1 Overall Conclusions Mathematical equations have been developed and are implemented in MATLAB by which the coupled and induced voltages in unshielded and shielded cables can be calculated. The values of the induced voltages obtained agree with the published results by different authors. For contact discharge ESD, higher induced voltages are observed upto 10 MHz for CSD, upto 2.5 MHz for air discharge and in the 20 to 100 MHz range for all the three terminations resistive, RC shunt and CMOS device. The induced voltages are higher in the case of contact discharge compared to air discharge or CSD. The induced voltage in an unshielded cable increases with the decrease in the rise time and distance, and increase in the peak amplitude and the damping factor for the CSD current model. The peak value of the induced voltage due to IEC contact discharge ESD at 8 kV for resistive termination is 625V and 7.8 mV for RC shunt termination. The peak value of the induced voltage due to IEC air discharge ESD at 16 kV is 6.25 V and 3.25 mV for RC shunt termination. The peak value of the induced voltage at the input of a CMOS device is 14 V for contact discharge and 0.6 V for air discharge. It can be inferred that RC shunt terminations are preferred compared to the resistive or CMOS device termination as the induced voltages are in mV range. In case of shielded cable, a generic program in Visual C++ to compute the induced voltages for varying parameters of the current waveform, length, height of the cable and angle of incidence has been implemented. This can also be used to calculate induced voltages for different cable configurations. Using MATLAB, the data imported from Visual C++ is used to calculate induced voltages. The equations developed give the voltages induced whose values are in close agreement with those published by other authors. The induced voltages are investigated for braided and unbraided shielded cables. The induced voltage and current in the center conductor is larger for a braided cable compared to a non-braided cable. This analysis estimates the transient voltages appearing at the input of the system connected to the shielded cable. This estimate can be used to develop appropriate mitigation techniques to protect the sensitive system that is connected to the shielded cable. It has been calculated by simulation that in shielded cables, the voltages induced due to radiated ESD is negligible thereby reinforcing the theory that shielded cables can protect equipment from high frequency radiated fields due to ESD. The effect of variation of the parameters such the cable length, height of the cable above the ground plane and the angle of incidence of the ESD pulse has been discussed. The peak amplitude of the cable sheath current decreases correspondingly with decrease in the length of the cable. This change in the occurrence of the peak is due to smaller value of inductance in case of shorter cables as compared to long cables. The peak amplitude of the cable sheath current correspondingly decreases with increase in the height of the cable. The sheath current decreases with the increase in angle of incidence, as the induced current is function of cos  Ã‚ ±i. The induced voltage in turn depends upon sheath current and surface transfer impedance of the cable. The induced voltages for a shielded cable of length 1m, height 0.1m and angle of incidence 30o are 1.4-10-8V for braided and 6.6-10-16V for non braided cable as presented in Table 3.3. Mathematical analysis is used to model the response of Very High Frequency amplifier to ESD generated radiated EM fields. Using MATLAB the effect of the radiated fields on the induced voltages in a VHF amplifier for various distances from the ESD source is calculated. It is observed that a greater part of the energy due to ESD simulation currents has frequency components in the range of 200 to 400 MHz extending to the VHF and UHF bands. So the VHF amplifier is susceptible to ESD events in this frequency range. If the distance between the ESD generator and the pickup antenna is decreased, the peak magnitude of the voltage coupled to the amplifier input terminals increases. The amplitude of the fields at antenna terminals, open circuit voltage at antenna input terminals, voltage at the input and output of the amplifier decreases sharply with increase in distance from ESD source. It has been observed that the induced voltages at the amplifier input terminals can be as high as 7.446 V with a rise time of approximately 1 ns for a distance of 0.5 m between the ESD generator and the pickup antenna as given in Table 4.1. This can cause malfunction of the electronic circuitry inside the amplifier. The spice circuit modeling with transient analysis concurs with the experimental results for air discharge on analog circuits. The zero crossing detector built with an opamp is more susceptible to ESD when compared to the RC phase shift oscillator built with discrete components. It is experimentally verified and the modeling also revealed that the oscillator circuit using discrete components took some time to come back to its initial working condition after the ESD discharge due to the slow discharge of the charges accumulated. In the indirect discharge it is seen that the ESD effect depends on both distance and discharge voltage. Higher discharge voltage and shorter distances produce larger transients and distortions in analog circuits. Direct air discharge of 15kV at the ZCD input damaged the opamp but the oscillator recovered after 750 µs. Direct air discharge of 15kV at oscillator output affects the output of oscillator for 1.4ms. The ZCD output remains high till the sine wave output of oscillator circuit recovers. The spice modeling also give the same results for discharge at oscillator output. In the radiative coupling the transient appearing on the ZCD output could be due to differential mode and the common mode could not be investigated. In the direct air discharge conducted at the input point of the ZCD circuit, there could be two types of coupling the direct capacitor coupling to circuit and near field coupling for the common mode. In this case also the common mode was not investigated, so the transients shown are only differential mode. In the direct air discharge at oscillator output, the differential mode and common mode transients were seen. But the voltage probes and current probes of high voltage and low rise time of 1ns range with an accuracy of less than 5% were not available. Hence the initial rise time and the maximum amplitude of the transient could not be measured experimentally with good accuracy. The digital switching circuit without decoupling capacitors at Vcc malfunctioned when an ESD event occurred at a distance of 35 cm from the circuit. The transient affected only the data stream and the circuit stopped functioning. Post discharge analysis revealed that Binary counter IC SN74LS393N had failed functionally (all output pins were malfunctioning). The importance of adding decoupling capacitors to the supply point of each of the ICs is verified. Experiments carried out to study the response of data to ESD in a digital switching circuit with decoupling capacitors at Vcc reveal that the effect of ESD on the data and clock depends on the position of trigger and also the plane of coupling. During discharge onto the horizontal coupling plane (HCP), the instance of occurrence of the discharge (when Data and Clock are High or Low) played an important role on the effect of ESD on the output data stream. When both data and clock are High, increase in data amplitude or data inversion occurs and also there is increase in the amplitude of clock. The distance at which the pulse is discharged onto the HCP reflects on the amplitude of the transient. During discharge onto the vertical coupling plane (VCP) there is a loss of data and transient with more than 50V peak amplitude is introduced. The discharge to VCP affected the digital data more than the discharge to HCP. Experiments are also carried out by varying the values of decoupling capacitors in the digital switching circuit and it is observed that smaller the value of decoupling capacitor, the more susceptible the circuit becomes to ESD. The decoupling capacitor with higher value of capacitance (0.47 µF) offered better immunity to ESD in our digital circuit because of its ability to pass only lower frequencies thereby rejecting the high frequency ESD transients. Experimental investigations of the TTL and CMOS logic gates reveal that CMOS devices are more susceptible to ESD than TTL devices due to the presence of a dielectric media in CMOS devices which can easily breakdown at high voltages. The output of CMOS logic gates deteriorated after ESD stress and did not recover after reset. It is verified experimentally that the susceptibility of a circuit to ESD in the mixed mode circuit can be greatly reduced by properly grounding it. In the mixed mode circuit used, the data is affected more by transients of various voltages based on the discharge voltage given when the analog and digital grounds are common. This reiterates the fact, when the analog and digital grounds are common the high frequency return paths from the digital ground (astable multivibrator circuit using 555 Timer) reach the analog ground (inverting amplifier using opamp) and affect the output. In the mixed mode circuit used when the analog and digital grounds are separated there are no transients due to ESD in the analog output. Hence separate analog and digital grounds are recommended. Direct air discharge of 12 kV twice on the GPIO pin of the custom designed 8 bit microcontroller diagnostic circuit resulted in the impedance of the board becoming very low implying there is a dead short between the VDD and the VSS rails of the microcontroller. The microcontroller shut itself down by enabling the thermal shutdown feature. The failure of all the three designed diagnostic tests involving digital ports, UART and PWM channels are observed. It is observed that the failure in the 8-bit microcontroller is through the Vcc and Ground pins when the ESD event was closer to these pins. This may be because of the capacitor across Vcc and Ground discharging into these pins due to the ESD event. For the ESD event at other pins, mostly malfunction was observed. The MSP430 launchPad with 16 bit microcontroller is quite immune to ESD owing to its inbuilt design and ESD considerations. This is confirmed experimentally by performing indirect and direct ESD tests at specified standard voltages. However direct contact discharge of 8kV given to the Tx-Rx pins of the jumper array resulted in the damage of the communication port of the 16 bit microcontroller MSP 430G2231 IC. The microcontroller MSP 430G2231 is found to be not communicating with the software and the program is not executable. The communication port (Rx-Tx pins) needs protection in the form of TVS diodes. The 8 bit microcontroller system configured to do a diagnostic check of its functioning during an ESD event had no extra on-board protection devices other than the on- chip protection. The 8 bit microcontroller did not withstand the IEC recommended up to 15kV air discharge perhaps because it was designed on a two layer PCB board. The MSP 430 launch pad with the 16 bit microcontroller on a four layer PCB was designed keeping in mind the ESD considerations. The 16 bit microcontroller also did not withstand the IEC recommended upto 8kV contact discharge at the communication port perhaps because of lack of extra protection. Continuous discharges on 8 bit microcontroller led to its thermal shutdown. But the continuous discharges on the 16 bit and 32 bit did not result in thermal shutdown perhaps because it was designed on four layer boards. All the observations from the previous tests and conclusions are put to use in the custom designed four layer board with 32 bit microcontroller interfaced with various components like the UART, audio interface, USB, LCD display and key matrix. All the standard design rules for PCB design are followed in the custom designed microcontroller test boards one populated with components having in-built on-chip protection and another board with extra off-chip on-board protection devices. In the custom designed 32 bit microcontroller system on four layer board it is observed that the placement of components on the board and board design played an important role in the systems sturdiness to ESD. The adherence to standard design rules such as split ground and power planes; proper component placement to minimize loop area; power supply decoupling using ferrite beads and decoupling capacitors; placement of connectors, user interfaces and output devices at the edges of the board; separating analog and digital sections has made the microcontroller boards quite rigid against ESD. Also the on-board protection devices at strategic locations such as the input/output, data and power points, communication port and at the input points of the interfaces in the custom designed 32 bit microcontroller system plays a vital role in the robustness of the system. The adherence to standard design rules has made the microcontroller board with components having in-built on-chip protection also quite rigid against ESD. The board with on-chip protection is affected by ESD with problems like malfunction or reset on power on with a damaged LCD interface module. The other board has extra on-board protection devices like ferrite bead used to isolate the noisy digital section from the analog section, decoupling capacitors for power supply decoupling, schottky diode used for ESD protection of USB and TVS diodes used at input points of microcontroller, LCD display, audio amplifier, UART and USB. The board with extra on-board protection devices has only temporary resets and is hardly affected by ESD, and the interface modules are also functioning normally. So experimentally it has been concluded that with adherence to board design and just in-built, on-chip protection the damages are mitigated but malfunctions occur which only recover on hard reset on pow er ON whereas with extra on-board protection devices included, the damages are completely eliminated, malfunctions are reduced and only temporary reset occurs. It can be concluded that not only standard board design rules need to be implemented it is also necessary to provide on-board protection against ESD by choosing appropriate protection devices and placing them at appropriate and strategic locations like the input pins and supply pins of the device. Experiments of direct air discharge are conducted on the insulators in FPGA/CPLD kit like seven segment LED display, LCD and FRC, and contact discharge conducted on the metal points like the switches, pins and the mounting screws. An air discharge of 8 kV on Liquid Crystal Display distorts the data but resets with power ON and an air discharge of 15kV damages the data on the LCD which cannot be restored on reset. An air discharge of 2kV and 4kV had no effect whereas an air discharge of 8 kV and 15 kV distorted the output on seven segment LED display but the display reset to normal with power ON. A contact discharge of 2 kV and 4kV on the HEX keys feeding the data to seven segment display had no effect but a contact discharge of 8 kV shorted the keys which in turn displayed wrong display data. All these devices had only on-chip protection by the manufacturer and these devices needed off-chip, on-board protection devices to make them less susceptible to ESD. Huge transients are observed when air discharge is carried out on the FRC cables connected to the DAC module. When a contact discharge of 2 kV is given on the input pin 187 of the mother baseboard the DAC output voltage reduces. FPGA 3s50 IC is affected during this contact discharge on the input pin. The DAC ICs are affected during the ESD discharge one due to direct ESD effects and the other due to indirect ESD effects. CPLD 9572 IC is also affected by ESD. Because of the ESD discharge in the surrounding and on the input pin of the FPGA/CPLD kit, the ceramic capacitor in the SMPS power supply connected to the kit has shorted and found to be damaged. This is an after-effect observed after the ESD test. The damaged capacitor has been instrumental in contributing to the damage of the FPGA and CPLD ICs. Decapping of the FPGA and CPLD ICs confirmed the failure of these ICs due to ESD. The input/output pin bond pad and the metatop layer of FPGA 3s50 IC is damaged and there is dielectric breakdown observed in CPLD 9572 IC which makes these devices highly susceptible to ESD. Future Scope Much effort has been put into characterizing the effect and impact of ESD on individual ICs, on different designed circuits and few systems such as FPGA/CPLD kit, microcontroller units with various interfaces. However, less time has been spent in modeling all of these circuits/systems and to observe their behavior towards ESD using simulation tools. An effort in mathematical modeling and simulation has however been done with susceptibility of electronic system and cables due to radiated ESD fields. Also circuit modeling has been done for the analog circuits. The experimental based conducted susceptibility tests on various electronic components have resulted in some new results. Some of these results have reiterated some of the known facts and some results have given rise to new thoughts in implementing ESD protected circuit/system. ESD threat level variation to electronic components depends on the discharge voltage of ESD source, discharge point, structure and design of the component. ESD threat to components mounted in systems may significantly vary from the threat to unmounted, individual components. New models need to be designed to predict the condition while the device is working in the system and using the computer simulations it is necessary to predict the ESD voltage, power and energy threats to system-mounted component. This is one area where the experimental results can be compared with the simulated results and the source of the threat, the point of discharge and its impact on the system can be confirmed. Also new protection schemes can be adapted to make the system less susceptible to ESD. Another area of interest where ESD tests can be conducted is in the area of high speed radio frequency (RF) circuits and systems. As the demand for wireless (RF) and high-speed mixed-signal systems continues to increase rapidly, providing sufficient ESD protection for these systems poses a major design and reliability challenge. This is due to the fact that in applying ESD protection to these systems, the protection system must be transparent the protection circuit must not affect the signal under normal operating conditions. A poorly designed protection system can generate impedance mismatches, causing reflections of signals, corruption of signal integrity, and inefficient power transfer between the signal pin and the core circuit. Broadband RF system protection because of ESD parasitic capacitance poses a greater challenge; alternate protection schemes may be necessary. This necessitates us to first understand effect of ESD on these high speed RF systems. However, there is little published information that provides performance analysis of RF circuits with various ESD protection design options scheme, which is attractive for operations in the multi-GHz regime.

Investigation looking At the Speed of Reactions :: GCSE Chemistry Coursework Investigation

Investigation looking At the Speed of Reactions Introduction The aim of this experiment is to find out how a variable can affect the results from a scenario set up in scientific environment. The experiment is to see how a certain variable will affect the amount of Gas produced from a Calcium Carbonate and Hydrochloric Acid Reaction. The Science Calcium Carbonate is a generally white or colourless mineral that is translucent. When compressed or exposed to great heat the mineral binds together in small to large clumps forming calcium Carbonate Chips, however left in it's formed state it is powder, a chalk like substance. I could use either forms of the Calcium Carbonate for the experiment. Hydrochloric Acid, is a clear, colourless to slightly yellow liquid with a sharp, pungent and irritating odour. It is a strong highly corrosive acid, soluble in water and alcohol but insoluble in hydrocarbons. The reason I am using Calcium Carbonate and Hydrochloric Acid for my experiment is due to the reaction when they are put together. A fizzing reaction takes place letting loose Calcium Chloride, Carbon Dioxide and Water. Word Equation ============= Calcium carbonate + Hydrochloric Acid ===> Calcium Chloride + Water + Carbon Dioxide Symbol Equation =============== CaCO3 + 2 HCl ---> CaCl2 + H2O + CO2 Prediction My prediction is that if the concentration of the acid increases there will be an increase in output of Carbon Dioxide from the reaction for example the highest concentration produce the most gas in the given time. I used a preliminary test to help in the prediction. I went and prepared marble chips and concentrated acid we tried the experiment, the results was clear that as in a few seconds it was almost finished. When we used very dilute acid it took so long for it to react and the amount of bubbles were much less than the first one. By using the results I can make the prediction of that, the rate of reaction is affected by concentration. Hypothesis If the concentration of an acid increase than output of gas will also increase. When the acid has a high concentration that means in that solution, compared to a dilute one there are more particles available to react with therefore the amount of times they will collide with the each other is more. Factors ------- There are many different factors, which effect the rate of reaction. Below is most of the known factors which effect the rate of a reaction: 1. The size of the particles of a solid reactant 2. The concentration of the reactants solution 3. Temperature of experiment 4. Amount of time available for reaction 5. Amount of solid reactant 6. Amount of reactant solution Particle size The reaction between calcium carbonate and dilute hydrochloric acid is

Loss of Innocence in The Catcher in the Rye Essay

Holden Caulfield, the protagonist in The Catcher in the Rye by J. D. Salinger is a complex young man, filled with many observations about the world around him. Most of his comments tend to be negative and judgmental; however he appears much more enthusiastic and about his younger siblings, and even his past. Events and situations that occurred, both in his past and over the course of the novel, show signs of Holden’s affection for innocence. Children also allow Holden to appreciate the need for a more positive attitude in his struggle through depression. Lastly, objects and places that have an impact on Holden’s attitude and positivity, symbolize the purity of youth. Although Holden maintains a fairly negative state of mind throughout the novel, he always becomes uplifted by the mention or memory of innocence, something that he deeply cherishes and attempts to preserve in this murky world that he finds himself trapped in. Events, both in the past and present, can bring innocence back into Holden’s thought path, causing him to feel an array of emotions. One of the most influential events that happened in Holden’s past was the death of his brother, and it has definitely taken a piece of Holden’s innocence. Allie’s death had a tremendous impact on Holden’s life, and it is one of the main causes of his depression: â€Å"I slept in the garage the night he died, and I broke all the goddam windows with my fist, just for the hell of it. It was a very stupid thing to do, I’ll admit, but I hardly didn’t even know I was doing it, and you didn’t know Allie† (Salinger 50). Although Allie is rarely mentioned in this novel, his death had a huge impact on Holden. The innocence of his younger brother had been lost with leukemia, which deeply saddened Holden. A plot event that also affected Holden’s innocence was the date that Stradlater and Jane went on. Holden knew about Stradlater’s nature with the girls that he dated, and he was very frustrated that Ward was about to go on a date with Jane, and old friend from Holden’s past. Holden’s innocent connection with Jane was being destroyed by Stradlater’s motives, and he wished he could have preserved the innocence of his old friend. The protagonist’s outburst to this loss of innocence was the event that lead to his premature journey out into the night, and the whole situation helped to spark the negativity that was being presented over the course the three days. Children always bring happiness and innocence to the main character, because they allow him to formulate meaningful memories, and to appreciate the innocence that they provide. Holden imagined a world of purity and innocence, and he wished he could create such a thing: â€Å"Anyway, I keep picturing all these little kids playing some game in this big field of rye and all. Thousands of little kids, and nobody’s around – nobody big, I mean – except me. And I’m standing on the edge of some crazy cliff. What I have to do, I have to catch everybody if they start to go over the cliff – I mean if they’re running and they don’t look where they’re going I have to come out from somewhere and catch them† (Salinger 224). This brighter world that Holden imagined brought his spirits up tremendously, and allowed him to take his mind off of his current depression. Holden’s younger sister, Phoebe, was a child who possessed both innocence and maturity. She was a very important person in Holden’s life, because the aura of innocence that she gave off deeply affected her brother. He loved his sister not only because he had the obligation to love his family, but because she was the best representative of innocence in Holden’s life. Objects and places that Holden came across in this novel also showed signs and pieces of innocence, and Holden greatly appreciated them. Allie’s baseball mitt was a symbol with extreme ties to innocence, because they allowed Holden to happily reminisce about his deceased brother. The museum is another thing that symbolizes the inevitability that is presented by the loss of innocence: â€Å"The best thing, though, in that museum was that everything always stayed right where it was. Nobody’d move†¦The only thing that would be different would be you† (Salinger 158). The Museum of Natural History symbolized Holden’s fear of changing or growing up, mentioning that there was always something different about him every time he went there. His analysis of the museum represented his desire to hold on to his own innocence, and to prevent changes that could cause its loss. Anything having to do with youth and innocence, whether it is a person, object, or event, has a very deep meaning for Holden Caulfield, and it even briefly uplifts his emotions. Salinger shows love through the innocence that was portrayed in various things throughout the novel, and he uses Holden as the ultimate symbol of love and innocence, which is slowly being whisked away by the inevitable process of the loss of this purity. For Holden, innocence holds the key to a brighter world, and Holden refuses to be victimized by the loss of innocence as he journeys through the city that refuses to sleep.

Economy of the Southern colonies between 1607-1775 Essay

The growth of slavery became intertwined in the life of the southern colonies in the 17th century and early and mid 18th century. Slavery slowly evolved from numerous factors. Such factors that lead to the mixing of slavery and the southern colonies’ life were social classes, geographical location and economic problems. The paramount example is Jamestown, Virginia, the first successful English colony. During the development of Jamestown, there was the unintentional creation of social classes. The higher classes were people who had land and money. These were the people who brought indentured servants to the New World to work on the wealthy plantations. The indentured servants would serve out their terms and be free. The majority that became free did not have as much as their previous masters. This brought about the lower class of people, the people who did not have land or money. The next lower class would be the Indians and African slaves. They were separated mainly because of their skin color. They were made as slaves and were forced to work on the plantations. The Bacon’s Rebellion in 1676, the indentured servants’ uprising, lead to the idea of the use of indentured servants dramatically dropped because the indentured servants held a threat to the peace and tranquility of the colony. The idea of slaves emerged as the primary labor force. Slaves were easily identifiable and were able to control through physical intimidation. It was because of Bacon’s Rebellion would massive number of slaves from Africa being to be imported. The majority of laborers on the plantations were African slaves. The plantation owners relied on the African slaves to work their plantations. Their plantations’ labor was needed because of the geographical location. The geographical location of the south made the use of slaves ideal. The land was flat with rich soil and long growing season as well as slow flowing rivers. This meant that farming was ideal in this region. To work the large plantations that would fill the large land, there would be a need of many laborers. The initial concept of indentured servants was dropped after Bacon’s Rebellion and the concept of slaves emerged. The plantation owners began to rely on the African slaves and depended on their labor over the vast land. If there were no African slaves, then there would be no labor and  therefore the land that would produce the cash crops would be gone and the economy of the south would fail. The economic section of the south depended on cash crops which were the paramount cultivation. The reason for having cash crops was because of the geographical location. The cash crops made Jamestown survive though selling the cash crops back to the Old World forming the economic basis, cash crops. There was a need for workers to work the plantations that produced cash crops. The use of slaves became needed and grew on the south so that the south needed the African slaves to survive. Through the outlook of Jamestown, Virginia, it is shown that slaves became intertwined in the economy of the Southern colonies. The social class of slaves being on the bottom made them the labor force on the plantations that formed because of the geographical location, which was large rich land and large growing seasons, was perfect for growing cash crops, the south’s economy. The social class, geographical location and economic factors of the South encouraged slavery because slavery was part of the South’s economy.

Green Sea Turtle essays

Green Sea Turtle essays The Green Turtle (Chelonia mydas) is one of the many species of turtles that inhabits the vast oceans. The green turtle is named for the greenish color of its fat found under its shell. It is a large, heavy reptile, usually about 0.7-1.0 m in shell length and about 90-140 kg in weight. The maximum length and weight are about 1.2 m and 375 kg respectively. (1) The green turtles upper shell is smooth and wide, the animal is brown, but when the light from the sun hits it, the green color from the fat is visible. The green turtle is found in warm, coastal waters around the world. (2) Sea turtles, in adaptation to an aquatic life, have limbs modified into flippers for efficient swimming. It feeds mainly on marine grasses. Most female sea turtles leave the water only when it is breeding season because the female needs to dig a nest on the land and deposit her eggs. But an unusual characteristic of the green turtle is that it will often emerge onto land to enjoy the sun. (2) The green turtle is classified as follows: In this paper the classification and origin of the green turtle will be discussed further. Their diet, mating habits, offspring, senses, and their economic value will also be discussed. There are four characteristics that have played a role in discussion of the relationship and classification of turtles. The characteristics include the dermal armor, the acromion process on the scapula, the astragalus-calcaneum complex, and the hooked fifth metatarsal. (1) The dermal armor (shell) is the interlocking osteoderms that are found lying above the vertebral column and the ribs. The acromion process in the turtle is an extension medioventrally on the scapula. (1) This unique characteristic allows for different muscle attachments in the turtle and accounts for the awkward positioning of the frontal limbs for walking or swimming. The astragalus-calcaneum complex has to do with the fusion of these two junctions to ...

MEDIA ETHICS Essay Example | Topics and Well Written Essays - 750 words - 1

MEDIA ETHICS - Essay Example However, he does not take sides with his country, the USA, in its conspiracy. Although the President releases a statement Wilson’s investigation, these are contrary to Wilson’s findings. Wilson does not accept the president’s misinterpretation of the findings. He therefore, goes ahead to publish his own account of the investigation, making it available to the public. This therefore, conflicts with Bush’s statement. Wilson was courageous and stood for the truth, not letting anything to compromise his truth. He refused to sit back and watch how the truth was being violated publicly. Therefore, he acted. By coming out publicly to make the truth available to the people, through publishing this article, I compare Wilson to the philosopher W.D, Ross, who developed a moral system called â€Å"intuitionist,† which claims that individuals are inherently aware of their moral obligations (Plaisance 10). Therefore, when Wilson came out fearlessly and published the article, no one had forced him to do so. Deep down, he knew he had the responsibility of performing his moral duties. Ross’ philosophy also holds that a person has a responsibility of honoring their moral standards and principles (Plaisance 10). Therefore, one of Wilson’s moral values must have been truthfulness, which is why he had to honor it by publishing the article to bring out the truth. In this philosophy, Ross also believed that the moral values one must honor include fidelity, justice, not harming others, and self-improvement (Plaisance 10). The values of fidelity, justice, and not harming others coinc ide with Wilson’s actions. He was against Bush’s propaganda of war with Iraq, since he knew this would cause harm to the Iraqis, as well as the US soldiers, who would die in the war. Wilson upholds justice, because he did not want the USA government to accuse Iraq falsely. Finally, he shows fidelity when he investigates the case, presents truthful findings, and ensures false statements

HOW MIGHT THE FAN PRACTICES THAT PRODUCE A CULT TEXT BE CATEGORIZED AS Essay

HOW MIGHT THE FAN PRACTICES THAT PRODUCE A CULT TEXT BE CATEGORIZED AS EITHER MASCULINE OF FEMININE; THIS ACCORDING TO GENDERED COMPETENCIES AND DISPOSITIONS AS FOUND IN THE AMERICAN SERIES TRUE BLOOD - Essay Example Vampires, two years prior, remained hidden from the Human Race; dwelling in the shadows while preying on human beings for their blood that was the vampires lifeline. This, however, changes when scientists in Japan create an artificial form of blood called â€Å"True Blood† that takes the place of human beings’ blood. They no longer have their survival controlled by the need for human blood. Instead, the vampire race is able to integrate itself into the â€Å"Mainstream† Human society. The resultant interactions are mutually suspicious with each race preferring its own company; often being intolerant of the other (Broyles, 2010, p. 56). Vampire blood, on the other hand, is categorized as being a kind of human narcotic: â€Å"V† or â€Å"V Juice† that is often sought after by the Human race. Sookie, the main protagonist is caught up in a fight between a human couple and a vampire male, Merlotte’s first, who were attempting to drain his blood. From this scene, the notion of women’s’ hospitability, non- violence and accepting nature is exhibited; this contributing immensely to the ensuing relationship that was to develop between her, Sookie, and the vampire, Bill Compton. From this relationship, a host of vampire culture and psychology is explored with great limitations being portrayed on vampire psychology. The receptive and understanding nature of Sookie epitomizes the goodwill and caring nature present in the female psychology (Hammond, 2006, p. 136). The murders of several women, all connected to Sookie’s older Brother Jason, provides the first season’s major plot. ... 136). The murders of several women, all connected to Sookie’s older Brother Jason, provides the first season’s major plot. Among the victims are Maudette Pickens, a sexual partner; Dawn Green, one of Merlotte’s servers; Grandmother Adele and girlfriend Amy Burley. He is addicted to vampire blood â€Å"V†; that is a human narcotic unlike anything manufactured at the time. The viewers’ knowledge of Jason’s innocence does not help much in easing the constant accusations and investigations carried out by detective Andy, in conjunction with Sheriff Bud, who target him as the main suspect in the investigations. The theme of masculinity comes out with the accusations, of the murders, and the constant harassment of the perceived suspect by the local authority. Violence and other acts of violence are socialized with the notion of masculinity while the feminine nature is credited with old age (Grandmother Adele), sensual and sexual pleasures as portray ed by Maudette and Marlette’s Dawn Green (Ghaill, 1994, p. 51). Friendship and enduring bonds are exemplified by the unwavering support given to Jason by two of his friends and workmates, Fortenberry and Lenier. Masculinity and endurance are two themes explored until in the end, another actor; Rene is exposed as the murderer; killed in a final confrontation with Sookie. Rene, Arlene’s fiance is actually Drew Marshall who having created a false identity goes about killing those women he considers gang-bangers; that is, women who have sexual relations with vampires. Friendship and unwavering bonds between the Male species is exemplified as being strong and long-lasting; this contributing to the fan
