Saving Private Ryan Essays - Operation Overlord, Operation Neptune

Saving Private Ryan June 6, 1944. Military forces converge on the beaches of Normandy for one of the most decisive battles of World War Two. America would call this a victory. History would call it D-Day. But for Captain Miller and his squad of young soldiers, the day after the landing on Omaha Beach would change all of there lives. They would get a special order from Washington ordering them to go on a personnel mission to save one life. One soldier lost three of his brothers in combat. One on Omaha Beach, one on Utah Beach, and the other in New Guinea. They realize this is not a simple mission to save a life but a test of their honor and duty. Their sole obsession-and their last hope for redemption. Upon arriving at Omaha Beach Captain Miller was faced with many problems. The Germans were awaiting the arrival of the American forces and attacked the ships landing on the beach before the troops were even able to exit the boats. Many of Millers men were lost on the beach along with many men from many other companies. Miller lead his mean along a wall on the beach and over took German forces to escape with most of this troop in tact. What he didn't realize was that on of the men lost on the beach was a Private Ryan. Captain Miller continued to lead his men into enemy territory despite the loss of some of his men. He then reached a friendly base set up. Upon arriving at the base he received orders that his mission would be changing. He was told of the Private Ryan that died at the Omaha beach invasion. He was also told of the other two Ryan boys from Iowa that had already died in the war. He wasn't really sure why he was being told this. Then the worst part came. He was ordered to try to find the one remaining Ryan brother. No one was sure where he was or if he was even alive. He was told of an earlier incident where three brothers from Iowa had all been killed in the war and the mother was left alone. The United States army was now ready to risk the lived of Captain Miller and seven of his men to try and save this one man just so his mother wouldn't have to lose her only remaining son. To Captain Miller this seemed a little extreme. Think of our mothers thought Miller and his men. They had no choice though, they were under orders. Along the way Millers company would stop by another American base to pick up an American soldier to translate to the German civilians they would meet along the way. They traveled to may abandoned and demolished remains of what used to be towns in search of Private Ryan. Miller lost many of his men along the way during encounters with German paratroopers and hidden German machine gun nests. But despite loosing many men they were able to continue. The met remaining parts of an American Paratrooping unit along the way to somewhat replenish their forces. But the paratroopers weren't in much better shape than Millers bunch. They continued in search of Ryan and finally found him in a town on the river. He was in a patchwork infantry trying to prevent the Germans from taking a bridge that was vital to the strategies of the United States Army. Private Ryan wouldn't leave with Miller though, he insisted on staying and fighting the Germans. He didn't want to be remembered as a coward. Miller agreed, and his men, battered and beaten, also agreed to stay and fight one last fight before going home. They managed to hold off the German advances until help arrived. They again lost many men in this effort but Private Ryan survived. Captain Miller has reached his goal and Ryan would make it home. I thought this was a very good book. I thought it made a very good point about some of the difficult decisions facing the men in the middle of a hostile environment in another country and the bravery shown by many men in the heat of battle. I can't say if I were placed in the same position if I would be able to do the same thing as some of those men.

The effect of temperature on the permeability of beetroot cells Essay Example

The effect of temperature on the permeability of beetroot cells Essay Example The effect of temperature on the permeability of beetroot cells Essay The effect of temperature on the permeability of beetroot cells Essay Although an apparent trend is illustrated by the experimental data plotted, I am reluctant to formulate a valid conclusion on the effect of temperature on the permeability of beetroot cells due to the variability of the results obtained.  Although five repeats were performed, the data collected is not reliable because of variation within the sets of results. This could have been due to various limitations of the experiment. At 30oC for example, the reading for absorbance of light in arbitrary units, was 0.12%. When compared to the results collected from other repeats at this temperature, this appears to be an unusually high value. Further examples of possible anomalous data were 0.03% at a heat treatment of 40oC together with 0.06% at 50oC. If these anomalous results were not included in the mean absorbance plotted, this could have had a significant effect on the overall conclusion. For example, had the reading at 40oC not been included in the mean, the reading plotted at this temperature of heat treatment may not have been lower than the mean result plotted at 30oC, as is shown on the graph by a slight dip. The size of the range bars causes one to question the reliability of the experimental data. These are especially large at higher temperatures of heat treatment (i.e. 70oC) where the gradient is steepening. At the lower temperatures of 30oC and 40oC, the range bars are overlapping. This means that one cannot be sure whether absorbance of light by the solution at 40oC does indeed decrease when compared to the previous reading. The range bars can be seen to overlap for the remaining temperatures of heat treatment, which means that it is hard to say within the error of the apparatus, what the exact value is. I am reluctant to draw a valid conclusion from the experimental data due to the significantly large percentage range at each temperature of heat treatment. At 60oC for example, the percentage range of the data from each repeat is approximately 300%. The limitations of the experiment lead one to question the precision of the experimental data and the conclusions drawn from them. A mechanised cutter was used to produce pieces of beetroot with the same cross sectional area. It was made certain that we cut downwards so that the bores did not converge. However the beetroot samples were not all of the same length. This could result in the beetroot discs having different surface areas and so causing different volumes of anthocyanin to leak out into the surrounding medium at each repeat of every temperature. This source of inaccuracy would have contributed to the variation and unreliability of the results and could be avoided through a technical improvement in the experimental design. When the discs were impaled on to a mounted needle, a small volume of dye leaked out from the damaged cells. This could not be measured and could have been potential dye lost into the medium, thus affecting the majority of readings for the absorbance of light. To overcome this source of unreliability, the beetroot discs could have undergone heat treatment in a fully permeable bag.  The reliability of the results can be questioned because no accurate method for shaking the solutions before they were poured into cuvettes was employed. The resulting intensities of the solutions could therefore have been incorrect. To avoid this source of inaccuracy a mechanical technique could be used to shake the solutions. The scales of the apparatus employed influenced the results obtained. For both 70oC and 80oC a reading of 2.00% was recorded. This was not the actual absorbance of light by the solutions at these temperatures because the scales of the colorimeters did not exceed 2.00. As a result the mean value plotted was inaccurate, thus any conclusions drawn from the data are unreliable. The experiment should therefore be re-planned using either fewer disks, reducing the time periods the samples of beetroot were left in water for or alternatively leaving the discs in increased volumes of water for 20 minutes. The scale of the colorimeter was only accurate to 0.01%. This may have affected the results at 30oC and 40oC, where there was a 0.01 difference. To overcome this source of imprecision and therefore unreliability the scale of the colorimeter used could be altered to give a reading correct to three decimal place. Although it is not certain whether using different colorimeters would have had any affect on the readings obtained, to ensure precision of the experimental data, the same colorimeter should be used to measure the absorbance of light by the solutions. Although a graduated pipette with 0.1cm3 markings was used to measure 6cm3 of cold tap water, to ensure high precision of the experimental data, apparatus with finer divisions could be used. This would allow a valid conclusion to be drawn from more accurate results.  In order to improve the precision of the experimental data, a digital stop clock could be used. The usage of a manual stop clock meant that there were slight variations in the incubation and staggered timings, and even slight variations in timing would introduce a high percentage area. A one-minute delay in removing the disks from the test tube following heat treatment for example would result in an error of 5%.  Further improvements that would provide considerable additional evidence for the conclusion would be to investigate an increased number of temperatures including a wider range between 50oC and 60oC, as an increased number of intervals would show exactly where the phospholipid bilayer of beetroot melts.
