Self Reflection Essay Example | Topics and Well Written Essays - 500 words

Self Reflection - Essay Example While it is a fact that men are physically stronger, this doesn't mean they are intellectually superior to women in any way, thus discrimination against women at workplace or other areas is totally unfair. Even in the fields where physical strength is required, it would be unjust not to give women a chance to prove their worth. But this has been happening for a long time in every society, discrimination against women is what resulted in women rights movement in different parts of the world. One wonders why there has never been a men's rights movement, it is because men do not need any such movement, rights are given to them on a silver platter by virtue of their gender. A movement for rights is always meant for the disadvantaged or underprivileged. Black rights movement took place because this community was denied their basic rights because of the color of their skin. In the same manner women had to fight for their rights because they were refused the same because of their supposedly weaker gender. While women in every part of the country have had to struggle for their rights and the battle is still on, the results of the movement vary from nation to nation.

Effects ofSarbanes Oxley Research Paper Example | Topics and Well Written Essays - 1000 words

Effects ofSarbanes Oxley - Research Paper Example In 2001, Enron Corporation, a USA energy company situated in Houston, hit its investors immensely when it filed for bankruptcy as a result of major corporate accounting forgeries carried out by its senior management and its auditor. The bankruptcy resulted in an estimated loss of almost $11 billion for its shareholders and the World saw a company with almost $63 billion market capitalization, file for bankruptcy (the largest dissolution in US history at that time) (Sterling, 2002). The major reason of the collapse of Enron Corporation was because of its fabricating and dubious accounting shams. The senior management of Enron was actively involved in recording fake Revenues within its accounting records. The practice carried out at the company saw the senior management of the company record Revenues on the basis of the present value of net future cash flows. This resulted in phony accounting treatment and misleading reports which was needed to match profits and cash in order to satisf y the shareholders. The company saw its stock price of $90 in the year 2000 fall to a meager $1 per share by the end of November 2001 (Rapoport et al, 2009; Sterling, 2002). This huge calamity saw the initiation of several new legislations including the Sarbanes Oxley Act, which was brought into existence in order improve the accuracy and the reliability of the financial statements and to provide a transparent picture to the shareholders (Rapoport et al, 2009). The legislation was passed by the US Congress in 2002 with a special focus of resuscitating investor confidence in corporations and others serving the capital markets. The title of the act clearly states its purpose. According to the title, SOX is â€Å"an act to protect investors by improving the accuracy and reliability of corporate disclosures made pursuant to the securities laws, and for other purposes.† (Golden et al, 2006) The act is named after US Senator Paul Sarbanes and US Representative Michael Oxley. The le gislation was put forwards in order to provide a stringent role towards any unscrupulous act. The act carried severe punitive measures against the wrongdoers and it provided increased powers to both the top management and the auditors. The act also enhanced its oversight role of the board of directors. The Act was introduced to look after several issues such as scrutinizing the Auditors, Directors’ and the top management’s roles. The act helped in reducing the conflict of interest between the shareholders, auditors, directors and the top management. Before its promulgation, auditors were self-regulated and were not answerable to any legislative or accounting body. Following the launch of the act, the Sarbanes Oxley legislation acted as a supervisory body which ensured that transparency was carried out while auditing the financial statements of a company. The Sarbanes Oxley act helped in overcoming the transparency issue. A research carried out by Stefan Arping and Zach arias Sautner concluded that the act helped in improving transparency. The research was carried out over a few US firms that were comparable on the basis of their operations (Arping & Sautner, 2010). The Section 404 of the act has also been under the limelight for quite some time now. The Section 404 requires companies to produce an Internal Control Report reporting over the adequacy of the internal controls and the financial reporting

Ultrasound is simply sound Essay Example for Free

Ultrasound is simply sound Essay Ultrasound is simply sound pitched above human hearing. Ultrasound is the part of the sonic spectrum which ranges from about 20 kHz to 10 MHz and can be roughly subdivided in three main regions: (A) low frequency, high power ultrasound (20-100 kHz), (B) high frequency, medium power ultrasound (100 kHz-1 MHz), (C) and high frequency, low power ultrasound (1-10 MHz). The frequency level is inversely proportional to the power output. High power, low frequency ultrasound does alter the state of the medium and is the type of ultrasound typically used for sonochmical applications. Table A shows the application of ultrasound (1). 2. 3. 2 Theory Two theories exist to explain the chemical effects due to cavitation: hot-spot theory (2) and the electrical theory (3 4). Hot spot theory has been experimentally shown that the cavitational collapse creates drastic conditions inside the medium for an extremely short time: temperatures of 2000-5000 K and pressures up to 1800 atm inside the collapsing cavity. A remarkable event during the cavitation collapse is the emission light under certain conditions (sonoluminescence). Furthermore, the collapse causes a couple of strong physical effects outside the bubble: shear forces, jets and shock waves. The electrical theory postulates that an electrical charge is created on the surface of a cavitation bubble, forming enormous electrical field gradients across the bubble which are capable of bond breakage upon collapse. 2. 3. 3 Sonochemistry in Aqueous Solution The reactive species formed during the sonolysis of water are similar to those observed radiolysis (Table B). Among the most extensively studies species are OH radical and hydrogen peroxide (H2O2), produced by the thermolysis of water molecules in the gas phase of the bubble, and recombination of the resulting free radicals H2O2 is formed in the cooler interfacial area of the cavitation bubble (5). 2. 3. 3. 1 Kinetic Analysis The chemical transformation which occur during sonolysis may occur in several different regions of the cavitation bubble (Fig C). Three regions of sonochemical activity in sonicated systems (6). Attack by oxidizing species such as hydroxyl radical (OH) or oxygen atom or thermolysis of chemical bonds within the substrate can occur in either the gas phase or interfacial region. OH is most concentrated in the gas phase of the cavitation bubble. It is presumed that aromatic substrates are attacked by addition of OH whereas non-aromatic molecules are attach by hydrogen atom abstraction (7) due to much stronger C-H bond in aromatic system. 2. 3. 4 Acoustic cavitation Bubble collapse in liquids results in an enormous concentration of energy from the conversion of the kinetic energy of liquid motion into heating of the contents of the bubble. The high local temperatures and pressures, combined with extraordinarily rapid cooling, provide a unique means for driving chemical reactions under extreme conditions. The origin of sonochemical effects in liquids is the phenomenon of acoustic cavitation. Ultrasonic waves traveling through a solution impose upon the liquid a sinusoidal pressure variation, alternately compressing the liquid molecules or pulling them apart by overcoming the intermolecular forces. As an ultrasonic frequency of 20 kHz, the liquid will be compressed and rarefied each second. Therefore, the distance among the molecules vary as the molecules oscillate around their mean position. If the intensity of ultrasound in a liquid is increased, a point is reached at which the intramolecular forces are not able to hold the molecular structure intact. Consequently, it breaks down and a cavity is formed. This cavity is called cavitation bubble as this process is called cavitation and the point where it starts cavitation threshold. A bubble responds to the sound field in the liquid by expanding and contracting, i. e. it is excited by a time-varying pressure (1 4). Two forms of cavitation are known: stable and transient. Stable cavities oscillate for several acoustic cycles before collapsing, or never collapse at all. Transient cavities, conversely, exist for only a few acoustic cycles (10). 2. 3. 5 Sonoluminescence (SL) During the acoustic cavitations, the emission of light was referred by the SL. During the underwater exposure of photographic plates, it was first observed, when these plates were irradiated with ultrasound in the solutions (11). Generally, the Hot Spot theory explains the origin of the sono-luminescence and sono-chemistry, which is widely accepted by the scholars. It simplifies the expansion of potential energy of a bubble, when it is concerntrated into the core of a heated gas, and which makes the implosion of that bubble. Sono-luminescence has been divided into two forms; single-bubble SL (12 13) and the multi-bubble SL (14), through which the information is gathered regarding the conditions during the implosion of the cavitation bubbles. Commonly, shock waves are the usually proposed mechanisms that are used in the SL during the implosion of the bubbles. Through this, the bubbles are converged at the center by these mechanisms (15). Hydroxyl radical is another mentioned that is being used in the SL, which produces the emission from the chemical species during their excited state (16). However, small changes in bulk parameters can bring significant influences in the nature of the emissions. The moment, at which the air bubbles glow in the water was observed by the first researchers and was then, known as the multiple-bubble sono-luminescence (MBSL). However, it is advised to observe this glowing condition in a darkened room due to the fainting characteristic of these bubbles. In 1990, two researchers; Crum and Gaitan observed the SBSL in its perfect conditions (17). Placing of a single bubble of gas was done in the liquid, in order to create SBSL. In this regard, an air bubble was injected in the liquid, which created the SBSL. Normally, the bubble was arisen after in the center of the cylindrical flask after its injection. However, the sound waves were bombarded that kept it in its place. Nowadays, elaborate setups are available and practiced by the researchers in their labs. Sono-luminescence requires around 100 decibels of sound waves, which can cause deafness in a normal person. Another factor that is imperative for the SL is the frequency of sound, which a human hearing cannot reach in its range. During the acoustic cavitations, the SL referred the release of light waves. Sono-luminescence is divided into two forms; single-bubble SL (12 13) and the multi-bubble SL (14), through which the information is gathered about the conditions during the implosion of the air bubbles. Commonly, shock waves are the regularly proposed methods that are used in the SL during this process. Through this, the bubbles meet at the center by these methods (15). The moment, at which the air bubbles glow in the water was observed by the first researchers and was then, known as the multiple-bubble sono-luminescence (MBSL). In 1990, two researchers; Crum and Gaitan observed the SBSL in its perfect conditions (17). A single bubble of gas was placed in the liquid to create SBSL. In this regard, an air bubble was inserted in the liquid, which created the SBSL. Sono-luminescence requires around 100 decibels of sound waves, which can also cause deafness in a normal person. 2. 3. 6 Heterogeneous systems: liquid liquid interface Ultrasound forms very fine emulsions in systems with two immiscible liquids, which is very beneficial when working with biphasic systems or phase transfer catalyzed. When very fine emulsions are formed, the surface area available for reaction between the two phases is significantly increased, enhance the mass transfer in the interfacial region, thus increasing the rate of the reaction. Ultrasound cavitation creates reactive intermediates that shorten the reaction time (18). 2. 3. 7 Ultrasonic System Types Generally 3 types: Ultrasonic bath, Probe system and Planar Transducers. 2. 3. 7. 1 Ultrasonic Bath Ultrasonic bath: originally manufactured for cleaning purposes (1). Fig Y shows the bath that has transducers attached to the bottom. The reaction vessel is typically immersed in the coupling fluid contained in the bath. When indirect sonication is used, the ultrasonic power which reaches the reaction vessel is relatively low as compare to other ultrasonic systems, such as a probe. In addition, obtaining reproducible results may be difficult because the amount of power reaching the reaction mixture is highly dependent upon the placement of the sample in the bath. 2. 3. 7. 2 Probe System Probe systems are being more frequently used for sonochemical research in the laboratory. This may be because manufactures are aware that this type of research is increasing and are providing equipment to meet the demand (19). Probe sytems are capable of delivering large amounts of power directly to the reaction mixture which can be regulated b varying the amplitude delivered to the transducer. Disadvantages in using a probe system include erosion and pitting of the probe tip, which may contaminate the reaction solution. Figure Z shows the probe type sonoreactor. 2. 9. 7. 3 Planar transducers This type of setup is typically made in the laboratory and consists of a planar transducer connected to a vessel which contains either the reaction mixture (direct sonication) or a coupling fluid (indirect sonication) into which the reaction vessel is immersed. Planar transducers capable of delivering higher powers than ultrasonic bath systems (1). However, they are difficult to scale-up.

Robotics Mechanics Introduction What is mechanics? If you've ever been around a physics teacher or engineer, they are always talking about mechanics, and its seems that no one really understands what mechanics really is. Quite simply, mechanics is the knowledge of design and construction of machinery. In robotics, this translates into the physical construction of the robot. Since every game is different (thus requiring different mechanical solutions), this section will be an introduction of the different options for robot construction available to the Robotics Team through the kit of parts from F.I.R.S.T. as well as the basics of mechanical design/planning. Before we begin, it is time for the one rule: There is only one real rule which should be followed regardless of the situation: Whatever I say is okay and whatever you say is okay. Repeat it with me: "Whatever I say is okay and whatever you say is okay." The important thing to remember is that we are all on a team. There is not one person on this team whose ideas are more valid than another's. Every single person has the right to express their ideas and every person should respect that right. I think everyone will agree with that, so I'll stop preaching. Where do we start? Traditionally, robot construction proceeds as follows: †¢ 1. Develop and Decide on Strategy Since every year the game changes, the primary task after the kickoff in January is planning the actual strategy for the team. This generally involves brainstorming in little groups and then presenting each strategy to the collective group. Then, pros and cons will be weighed for each strategy and then a strategy will be selected. From this strategy can be developed necessary task for our robot to execute, which leads to an actual working design of the robot. Before we move on, everyone should understand that no one is always correct. The very nature of any engineering project (including this one) makes it impossible for a single person to design the best project. That is why it is necessary to have a lot of people brainstorming together on the same project. More people also make troubleshooting a lot easier, so it is important to not only question your own ideas, but also those of others. Actually, please, please, please ask questions. In fact always question. There is no design which is perfect and no idea which is flawless. Continually question, dissect, take apart, stare at every single part of the robot.

The Problem Of Mental Illness - 912 Words

Mental illness affects many people throughout the United States each year. Some people classify it as any psychiatric disorder that is the cause of untypical behavior. Many years ago, doctors locked up mentally ill patients in mental institutions and basically forgot about them. Medical professionals housed the mentally ill in different corridors of the hospital. Sometimes, they stayed in isolation and were in some type of restraints. Once government officials realized that neglect was getting out of control, deinstitutionalization became a hot topic. Deinstitutionalization started as a government policy that became a long-term trend to lessen the burden on professionals in mental treatment facilities. Its intent was to have fewer treatments in public hospitals and fewer people residing in the facilities. The deinstitutionalization movement began in the mid-1950s and government officials were hoping the process would improve the treatment toward the mentally ill (Lauer, 2014). Addi tionally, there were several drugs that helped the mentally ill and officials believed that those people would get better care by living in a community based environment. Moreover, it was another way to balance the government budgets. However, the impact on human service agencies, specifically community mental health facilities, prisons, and probation offices, was less than adequate because all of the unknowns and the social stigma attached to the mentally ill.
