How the Brady v. Maryland ruling was used in People v. Cwikla and Research Paper

How the Brady v. Maryland ruling was used in People v. Cwikla and People v. Steadman - Research Paper Example However, he appealed the case where case was reversed because of prosecutorial misconduct and errors that were committed by the court. The defendant was convicted of criminal possession of a weapon second degree and manslaughter second degree where they had killed Maxine Peterson on May 28, 1988. The only prosecution witness who could have identified the defendants was a drug addict and user and had previously committed two felonies. In that, at the period of the prosecution he was on probation for one of the previous convictions where three open felony charges were pending prosecution. The defendants in the case sought a pre-trial disclosure of any promise of leniency made to the witness in altercation for his favorable testimony against the defendants. The prosecutor revealed some of the arrangements that were made with the witness, but did not advise the defendant that the Assistant district Attorney had agreed that Malloy the witness was not required to go to prison for the pending charges in case he testified against the defendants. Brady v. Maryland, 373 U.S 83 (1963) in these case it was established that turnover of information is imperative and is a requirement under the Fourteenth Amendment due process clause. It was further held that the subdual by the prosecution counsel of proof in favor of the accused person upon the appeal by the defendant violates due process. This is because the evidence that is being suppressed is material to establish whether the defendant is guilty or punishment irrespective of good or bad conviction of the trial. This has now been illustrated as the brandy rule. In the case of People v. Cwikla, the Brady rule was used in this case because the prosecutor failed to confirm correspondence in support with the informant application for parole. In this case, the court alleged that the prosecution is under the obligation to disclose to the defense counsel any

Response Paper - Essay Example In addition, the context that the author uses is more persuading as compared to Frye’s article. This is because Brady uses a more personal perspective when putting across her points. Here, Brady uses herself as the main point of reference, which makes the argument livelier and convinces more because it is written from a personal perspective. The choice of words in Brady’s article is also strategic in that the article is easy to comprehend by almost any individual in the society. This implies that it was written for the general audience. It also incorporates an interesting theme, which any person would like to read. On the other hand, Frye’s article argues using a second individual as the point of reference. This makes the article less convincing as compared to one that is written from a personal perspective. In addition, the choice of words by Frye is carefully done for a specific group of the population; the highly literate. Frye is also judging when he gives a general perspective on how most people think and misuse the word ‘think’. This article is not only less convincing because of the judgmental style used but also because of difficult word choice application. The title of the article is also negative and discouraging. The author also uses colloquially especially in the title. The main theme that the author adopts, which is that thinking takes place when an individual puts down ideas using the right words is confusing. This is because this theme does not specify what is meant by ‘right words’. This is in contrast to Brady’s theme, which is straightf orward requiring less effort in understanding. Brady’s theme gives the reader an immediate idea that the article would encompass certain reasons as to why the wife is needed. Frye’s article is confusing. This is one of the main reasons why I view this article as least

Chemicals Needed for Muscle Contraction

Chemicals Needed for Muscle Contraction The goal for this lab was to determine the conditions that demonstrate what chemicals in muscle fibers are necessary for contraction and which ones prevent muscle contraction from occurring in a simplified system in order to determine the minimum requirement for contraction. Methods In order to prepare muscle fibers, a single thread was obtained from a mass of glycerinated muscle fibers which was about 0.5 mm in diameter. The muscle was a rabbit psoas muscle in 50% glycerol (stored at -10 degrees C) obtained from Carolina Biological. In order to have an observation of what was taking place with the muscle, Nikon E400 was used. The fiber was placed on a slide in the presence of 0.05 M KCl and 0.005 M K phosphate buffer (pH 7). The first step was to detect the minimum requirement solution for muscle contraction to take place. This was done by using the following solutions: 0.001 M MgCl2, 0.001 M CaCl2, and 0.1 M ATP. The requirement was determined after observing the changes taking place when each of the solutions were added to the muscle separately, in combinations of two, and all three solutions together. After the minimum requirement was determined, chelators were used to see whether they inhibited contraction in the presence of the solution that caused contraction. The chelators were 0.002 M EDTA and 0.002M EGTA. The EDTA binds Ca ++ and Mg ++. EGTA binds only Ca++. The chelating agents enhance the solubility of magnesium and calcium and allow them to spread out of the muscle fibers. This causes the removal of the ions from the actin and myosin environment. It was important that the chelators were added before the contracting agents when inhibition was being tested. Otherwise, it would be impossible to detect any changes once the contraction has taken place; contraction is not reversible once it occurs in a simplified system. Then Solution A and Solution B were used to examine the localization of myosin and actin in the myofibrils. Solution Aà ¢Ã¢â€š ¬Ã¢â€ž ¢s function was to solubilize and remove myosin in the form of monomers from its loci which is in the myofibril. Solution B had the same behavior as the actin. The Solutions were placed on the myofibril to see changes that took place and observations were made. Discussion and Conclusion During this lab, using the microscope we examined the changes that took place when certain solution were introduced to the rabbit psoas muscle fibers. The solutions caused contraction, inhibited contraction to occur, or had no effect on the sarcomeres at all. We used glycerinated myofibrils from rabbit psoas muscle which is a type of striated muscle. Rabbit psoas muscle was a good model to use for this lab since the fibers are long and straight. Also one other advantage was that there were not a lot of connective tissues connecting the muscle fibers together. This was an in vitro model meaning that experiment was completed outside the living organism. The Phase Contrast with magnification of 10X/ 40X was used during this lab to examine the slide because the cells are transparent and Phase Contrast is the best option to use in order to have a good resolution. Under a microscope the myofibers were striated and they had a repeating pattern of bands and lines. The pattern was caused by parallel organization of protein filaments within the myofibrils. In the myofibril, there are two types of filament- the thick filaments which consist of the protein myosin and thin filaments composed of the protein actin. As demonstrated on Table 1, Mg2Cl2, Ca2Cl2, and ATP were the solution used to determine the changes taking place with the muscle. All of the three solutions were placed on the slide which consisted of a thread of muscle fiber and contraction of the muscle was observed. We could tell when contraction was taking place because the fiber was short in length and it was easy to see the changes such as the shortening in length and the color change. When Mg2Cl2 and Ca2Cl2 were added individually to the fiber, nothing happened. However, as soon as the ATP was placed on changes were easily observed. ATP caused muscle contraction by itself. The sarcomeres in the muscle fiber shortened in length and the color changed from light yellow to darker yellow. However, in order to make sure this was the minimum requirement for muscle contraction, we added Mg2Cl2 with ATP and Ca2Cl2 with ATP. With the MgCl2 and ATP, the contraction occurred immediately as the solutions were added. The contraction was even faster than the ATP alone. Then ATP and Ca2Cl2 solutions were introduced and this also caused contraction. Even though the combination of the two solutions caused contraction to occur faster than ATP by itself, it was slower than the solutions of ATP and Mg2Cl2. As a result, we concluded that ATP was the minimum requirement needed for the cells to contract. All the solutions that caused contraction were not in one dimension because every component of a sarcomere was facing changes except the A band which stayed the same. The I bands, the M line, the Z lines, and the actin and mysosin- they were all decreasing in length in order to cause contraction. At the end, it was determined that ATP was the requirement for glycerinated muscle contraction. When there is no ATP present, the myosin heads in the muscle will not be activated and it would not bind to the actin. In glyceri nated tissues, the combination of KCl and MgCl2 with ATP increased the strength of muscle contraction. This was mainly due to myosinà ¢Ã¢â€š ¬Ã¢â€ž ¢s high affinity for these ions. Table 2 shows whether contraction was inhibited in the presence of chelating agents, EDTA and EGTA, when it was used with the main solution that caused contraction, ATP. EDTA and EGTA did not inhibit contraction from taking place, but the contraction was slower than when ATP was present. EDTA is a chelating agent that binds Ca++ and Mg++ and EGTA is a chelating agent that binds Ca++. The chelating agents increase the solubility of Mg 2+ and Ca2+ so that they can leave the muscle fibers. With ATP and the chelating agents, contraction occurred and there was no inhibition taking place. Table 3 shows two different solutions, Solution A and solution B, and their effect on actin and myosin. As shown in the table, solution A had KCl, phosphate buffer, Na pyrophosphate, and MgCl2 while solution B had phosphate buffer. Both of these solutions did not cause any contraction in the muscle based on our observations. However, changes were observable because in both cases the fibers changed color; they became lighter yellow. This meant that the muscles were not contracting. Solution A made the mysosin more soluble and solution B acted in the same manner as the actin. When comparing the muscle in living tissue, the glycerinated muscle system is different. The glycerination technique eliminates ions and ATP from the tissue and disrupts the troponin/tropomyosin complex. When the complex is interrupted, the available binding sites on the actin fibers are no longer blocked ( Cell and Molecular Biology). As a result, Ca2+ is not one of the requirements to cause contraction. On the other hand, since there is no ATP is in the glycerinated tissue, the myosin heads cannot be activated to cause contraction. After the muscle contracted it did not relax since there were no opposing muscles to pull it. Also, muscle fibers do not contract when there are no stimulations or nerve signals and this was one of the differences with glycerinated muscle and the living cell muscle. Errors could have occurred in this lab if one used very thick muscle strands. Having thinner strands were better to have good results. Also, it is possible that much of the calcium was still in the sarcoplasmic reticulum of the glycerinated muscle, which would have lead into incorrect results. All in all however, the lab was successful and we have obtained what we were looking for- what solutions cause contraction, which ones inhibit, and what is the minimum requirement for muscle contraction.

The European Balance :: Euros Money Finances Essays

The European Balance New Year’s Day 2002 had me in Dijon, France, where I first had possession of euros, the new common currency for 12 European nations. It was sunny out, and the automated teller machine was on the corner of a town square, where an old cathedral stood tall, peering over centuries of architectural variety. It was quite typical – very European, that is – because I felt myself on the brink of novelty amidst a haze of antiquity. It was like a stylish, young woman, donning Yves St. Laurent and swaying past the Pantheon in Paris; it was a suave Italian driving his Smart Car in front of La Scala. Europe has a penchant for surprising developments and we feel compelled to admire every swing of the Continental pendulum. At the hotel the concierge sat behind a wooden counter and methodically laid out the new coins for us to see. â€Å"500 years,† he said in a thick, French accent laden with exasperation. â€Å"[For] 500 years,† he repeated for emphasis and to finish his thought, â€Å" we have had the franc.† â€Å"To change to the euro – it is an enormous difficulty,† he told us. He shook his head while further expressing his dismay through the peculiar amalgam of a grunt and a sigh, one that can only be heard in France. Perhaps most amazingly, he managed to make this noise with a French accent. Several days later I arrived at Madrid’s Chamartin train station and I got into a taxi. After a few minutes of silence, the driver – an old man with his gray hair pulled back into a ponytail – asked me, â€Å"Pesetas [or] euros?† The whole motivation behind withdrawing euros in Dijon was to have cash immediately upon arrival in Spain; so here I was readying myself to pay for a Spanish taxi ride with money I could have just as easily used in eastern France, where I withdrew it. â€Å"Euros,† I replied to his question. â€Å"Euros,† he mocked with a snide, condescending tone. He punctuated his disgust with a slight chuckle – it was his way of telling me he did not see what the big deal was about this new currency. As far as he was concerned, the peseta was perfectly fine and the euro was an immature exercise in futility.

Fahrenheit 451 Symbolism-the River Essay

In Ray Bradbury’s Fahrenheit 451, Montag’s escape through the river svmbolizes his salvation, along with several other things. . In several other instances besides the river, water is used to contrast fire and to thus show the difference between good and evil. Also, the forest through which the travels river symbolizes the innocence of mankind before civilization. This is merely a scaratch on the surface of this novel’s seemingly endless symbolism. Fahrenheit tells the story of a fireman named Montag whose job is to set fire to books in order to maintain society’s ignorance. When Montag kills Beatty, the Fire Chief, he decides to run from the world that he has lived his whole life in. His newfound friend Faber, another person on the outskirts of society, tells him that he will be safe if he makes it to the river. This is an illustration of literal salvation. Rivers often represent â€Å"divine emmissaries, life, and the enterance into the afterlife† (Jobes 1341). â€Å"After a long time of floating†¦ [Montag] knew he must never burn again† (Bradbury 141). This shows that the river changes Montag or is at least the cocoon in which he stays while he undergoes a metamorphisis into what is basically a different person. Also, it is interesting that, in the old South as well as in Biblical times, the baptisms of new Christians often would take place in the nearest river or creek. Montag’s journey in the river seems to be a baptism of sorts, as it frees him from the shackles and chains of his former life. The river, however, is only the vessel in which Montag travels to the heart of the forest. The forest is the â€Å"abode of man in his state of innocence, and a Hebrew symbol for kingdom† (Jobes 594). In the novel, the forest and the river are likened to one another at times, such as when Montag describes the forest floor as â€Å"a dry river smelling of hot cloves and warm dust† (Bradbury 144). When Montag several men who, like him, are on the outside of society looking in, they are at the old railroad tracks tht cut through the heart of the forest like a rusty dagger wielded by the filthy hand of industry. It is here that he finds his real redemption. The river is not the only use of water as symbolism in Fahrenheit 451. Water symbolizes â€Å"baptism, cleansing, resurrection, and is a source of both good and evil† (Jobes 167). Water is used on numerous occasions to contrast with fire, wich is representative of â€Å"divine love, fervor, and life, but also divine anger, destuction, and death† (Jobes 571). Usually, they contrast good and evil, and although fire is generally associated with evil, its symbolism begins to change toward the end of the novel When Montag sees the fire the men in the forest are using to warm themselves, he realizes â€Å"he [has] never thought in his life that fire [can] give as well as take† (Bradbury 147). The fire is a metaphor for Montag; he finally realizes that he can change the world for the better instead of for the worse. Ray Bradbury’s novel offers a rich tapestry of symbolism to all those who read it. Bradbury weaves a seemingly endless amount of symbols into his story in a way that is wonderfully eloquent, distinctly American, and easily accessible to the casual reader. His passionate cry against censorship and engaging story has enthralled readers for the past 50 years. He uses symbolism to help get his point across, and thus makes the story work on a deeper level. Through symbolism, Bradbury has found a way to affect the reader in the very core of their being, and he has made this novel one whose jarring imact stays with the reader long after they have turned he final page.

Crt Monitors and Active and Passive Matrix Displays

CRT MONITORS AND ACTIVE AND PASSIVE MATRIX DISPLAYS The texts â€Å"CRT Monitors† and â€Å"Active and Passive Matrix Displays† gives us the necessary basic knowledge about the types of monitors. Most desktop computer systems sold now by default come with LCD monitors. But if you are one of those who want to know the difference between CRT and LCD monitors, these texts are immense help. To start with, a CRT monitor in general is nothing more than cathode ray tube with millions of diminutive red, green and blue phosphor dots.The working principle of CRT monitor is sustained by the theory of electron beam traveling across the tube to the area of deflection system where the beam is given direction to a specific pixel on the screen. The first CRT monitor has been invented in 1970s. However, monitor was greenish and the only possible sphere of usability was text-based computers. On the other hand, it was just a start. In 1987 when the VGA display system was invented and CRT monitors took a step into the astonishing success and recognition. As years went by, new technology of monitors was invented.These were an active and passive matrix display technology using monitors. First of all, these monitors were different from CRT because of the new thin film transistor technology. It was that kind of technology where particular row was switched on and a charge was generated and sent down the column. As result, the pixel appeared on the monitor at the intersect place of the row and the column. Moreover, it was a revolution in making computers portable. To sum up, it is essential to mention that technologies are not staying fixedly so it is natural that one technique displaces other as time goes by. 285 words
