Genetic Essays (825 words) - Molecular Biology,

Genetic Engineering For many years, man has been advancing his race through technology. Many things through those were questionable and questionable, but none are close to a certain technology today. And that would be genetic engineering. What exactly is genetic engineering? To put it shortly, it is where scientists splice, alter, and manipulate genes of one thing to how the scientist want it, and even insert that gene into a foreign host. This technological tool is too powerful for us to handle. It is advancing faster than we can expect. Because of this fact, genetic engineering raises many moral and ethical issues while also showing signs of many dangers. This controversially technology could be looked at two ways, one religiously and the other, scientifically and economically. First, let's talk a religious point of view on genetic engineering. With the current knowledge we have today in genetic engineering, life can easily be created and manipulated to one's liking. How can one "Play God" by creating and altering life at one's will and not at all feel guilty? Haven't we learned that trying to be on a level as God is a punishable act? Such examples are ones such as the destruction of Babylon. People at that time tried to build a tower high enough to reach God, but it was destroyed, a punishment by God that warned us of what will happen if we tried to get powerful as him. People say that God gave us the knowledge to discover. If this is so, did God give us the knowledge to make the atom bomb so we could wipe out cities and vast lives in an instant? Did God give us the knowledge to make deadly biological weapons to kill each other with? And did God give us the knowledge to be so advance in warfare today that the world could be destroyed in minutes? God did not give us the knowledge to do these things or for genetic engineering. Man ignorantly chooses his own way and chooses to venture out doing things that are wrong. So who are we to decide what sex a baby should be, how it should look, and what skills it might have? These are just few of the many questions raised in a religious point of view. Next, is the scientific and economical view. One goal of genetic engineering is to make products more efficient. Things such as crops and other plants are one of the things that have been experimented on and even released into the environment. This is especially dangerous because scientists are not fully sure of what could go wrong. A genetically altered crop or plant could become dominant and take over all of the its like species and become a problem such as becoming major pests. There have been many cases where non-indigenous plants introduced into a different environment served no use and became major pest problems. But even more dangerous altered plants are genetically altered humans. The functions of all the genes are not known, only these of a very small percentage of the total genes in organisms such as humans. So why would a scientist take a risk, not knowing the full potential dangers it might cause, such as having an effect on other genes? Privacy is another major concern. What if a sing drop of a person's blood could reveal all the faults of that person? When will we wake up in a world where everyone has permanent records of what defect will come up in their lifetime and what other things they are susceptible of getting. What if insurance companies got hold of these records? Could people be refused of health insurance because of these facts? There are many examples where people have been refused of some health care because of genetic screening. Not only that, in a recent poll in Time magazine, a question was asked if a person whose genetic profile shows potential problems pay higher health-insurance rates than someone whose profile does not? Only 8 % answered yes while the majority 88% said no. Obviously even the majority of this nation does not want to be genetically profiled. One recent controversy that has come up is cloning. With some DNA of an organism, scientists are able to make and exact copy of that organism. A sheep and a monkey have already been successfully cloned, and with the current technology, humans could also be cloned. This raises the most ethical and moral issues because many questions would be raised about the clone.

Physics-Inclined Plane Lab Essays

Physics-Inclined Plane Lab Essays Physics-Inclined Plane Lab Paper Physics-Inclined Plane Lab Paper If an object is placed upon a surface that is inclined at a certain angle then that will decide the acceleration in which the object is going down the inclined plane. When looking at an inclined plane it is important to see what forces are acting upon it to see what the object is doing. In our case of there was Fn, Gravitational Force and, Fd. These forces act upon the object to see where it is going. In an inclined plane there will always be at least two forces acting upon the object which would be weight (pointing downwards) and force normal (pointing forwards). Force normal as always been the opposite of the gravitational force, but that is not true because we now of horizontal planes, but this is a inclined plane and the truth is that Force Normal is always perpendicular to the surface the object is on. ength of Ramp: The length of the ramp was always constant as it was 100 cm. The length of the ramp never changed as the car always began accelerating for a total distance of 100 cm Distance of Motion Detector from Ramp: The distance of the motion detector and the ramp was about 40 cm. With there being 40 cm between the motion detector and the ramp the data that we collected could be extremely precise. The data would be precise and our acceleration would pin point. The only problem we had at the start was that it took time to set the motion detector to detect the car until we found the perfect place for the ramp to perceive the data. Coefficient of Friction: The coefficient of friction was taken away because of the equipment that we used. For example we had the frictionless car that helped reduce the friction greatly; also the ramp let the wheels fit into the plane which made the friction almost definitely According to our graph above which is the points we got from our lab; we can say that as the angle of inclination increases then the average acceleration would increase. Except for a few exceptions its is proved through our graph that the acceleration is increased as the angle is increased, but for those exceptions we may be able to say that error was involved as 30% is quite high. We found our data using two different methods and different numbers for each and generally got different answers. By looking at all of our data we can come to the conclusion that the angle of inclination does not affect the acceleration. Like our Projectile Motion lab that we have done recently the projectile went a certain distance at a certain angle and then after changing the angle the distance would decrease after a while. We can say the same for this Lab as that when the angle is lower than 90 the acceleration would increase until the angle is above 90 and the acceleration will decrease again. This is because if one looks at this problem it makes sense. The car will go much faster until the ramp if perpendicular to the ground and when you lower the ramp to 180i then the car will barely have any acceleration considering there is no friction. In our Lab we can calculate that there is about 32% error which is very high, but for several reasons is true. I believe that this 32% error was taken because of random and systemic errors meaning that what we did made the error much higher than it should be and also the fact that the instrument was a bit hard to work with. One random error was that we definitely did not collect data and that if we did collect more data the results would be much more precise then they are. Another Random Error was the time that we used, we may have not used the time to our best accomplishment as it took much time to prepare and also take all the data down. A Systemic error that occurred was with the frictionless car as the motion detector took a lot of time to detect the car and we had to measure at which height the car would be detected. This took several pre trails of which none were counted. Our results from which we got from the lab compared to the gsin? results were not that much different, however there were certain points that did not match up. From my overall look I can say that the design and method of the investigation was good. There were few weaknesses in the lab, such as the motion detector taking time to set up as well as getting it to work properly which may have increased the error. Another weakness was our time management which was not up to par, where in this case we were at times working to fast and rushing a lot as we didnt have much time left which affected our data greatly. Another weakness was when averaging the acceleration we only had constant acceleration for about 1 second in which we averaged those numbers together. The precision of the data was decent as our motion detector was quite accurate. For the few weaknesses I had I can say there are simple solutions for them to be avoided next time. With the motion detector I think we could first find a proper height for both the ramp and the car to be placed at and whenever we raised the ramp we would raise the motion detector by the same amount. Next was the time management where as always we could have stopped rushing and taken our time even though it was scarce, this was because we had to do this lab during a time with constraints. The last weakness was with the acceleration and my solution is to increase the length of the ramp and let the car run for more time and thus we will get a more detailed acceleration. To remove systemic/ random error next time we would have to make sure we have more time for the experiment and set up properly.

Judgement analysis paper - Essay Example The key message of the book is that leaders are basically assessed by the quality of judgment they make throughout their occupation. It is always thought that judgment is something that cannot be learnt rather it is advocated to evolve over time. However, Tichy and Bennis have found method to assist leaders to improve their capability to make effective judgment. They also have articulated leadership judgment as a simple and understandable procedure. Leaders at every organizational level make judgment regarding employees, strategy and crisis situation. Tichy and Bennis demonstrated the type of knowledge required in order to make successful decision and how leaders can effectively use such knowledge in order to execute the judgments (Tichy and Bennis 1-285). In the first chapter, the authors proclaimed that effective leaders not only make better decisions but they are also capable of making the appropriate judgment. Effective leaders are those who are better at entire judgment procedure that starts from observing the requirement for an appeal of judgment, to framing the organizational issues, to figuring out the serious ones and to organizing as well as stimulating the teams towards accomplishing the organizational goal. Tichy and Bennis in their book have stated that there is a framework containing three crucial areas within which every judgment are made. Among various other judgments, the decision regarding people are most critical than decisions taken regarding strategy or on any crisis situation. The authors stated that effective judgment is a procedure rather than an event. Every judgment starts when a leader identify the requirement of taking decision and frame them accordingly. The procedures of making judgment continue through e xecution and alteration phases. The authors also stressed the significance of acquiring sufficient

Visual Analysis Art - Essay Example According to, For Entry to University and College, the structure acts as a base for the students to recreate markedly on the hot days as denotable from the freshmen. It allows the students to skate, walk, and even cycle at the vicinity; furthermore, the location of the structure creates a splendid walkway on and off along the campus especially in the winter periods and even towards the engineering mall. The structure has had it challenges in equal measures despite the marvelous attraction and praise. Consistent with, A University of Tradition: The Spirit of Purdue, the threat exposed by the structure to small children is quite insurmountable to warrant its operations. For instance, in April 2001, the structure had stalled for some periods. It even attracted the attention of the administration to the extents of even rethinking of laying fences around the structure. Massive pressure created by the water jets continually knocked children on the along the structure thus inhibiting or eve n concealing the rather finely designed and projected engineering work. The local people however permitted their children to get jovial around the structure, but this was to conducted under supervision of an older person, for instance their parents. While the structure was excellently designed, personally I feel that it does not meet the thresholds for safety. Possibly, the location or even design architecture had gross errors. In any engineering or artwork safety comes first. Probably redesign of the structure could restore the desires of the initial creator. The conspicuously high pressure is inconsistent and inapplicable to the ambience habituated by children. Possibly, design of a small obstacle or fences around it could probably reassure the essence of the structure. The implementers of the design did a laudable job by using long term existing materials including concrete and blocks (Pipes, 2003). Landmarks similar to the ‘Engineering fountain’ are susceptible to t he erosion factors, rain and water being the chief causatives of the wide spanning corrosion conditions. The choice of the blocks ascertains the durability anticipated by the initial designers of the structure thus exposing the envisaged long existence. Goods application of cement and quality exhibits unnatural strength in the material structure as notable from the pyramids of Egypt and the highly erected quality expands the established feature for the far based visibility of the structure. At night, the highly adorn lights paints the section under which the projects sits sparkling cream appearance that even adds to the already outstanding form to expound on the beauty. While the art points to heaven and at top of it during the night light shines resembling the biblical star that directed the Wiseman to the birth place of the king (Jesus). The vast space allocated near it offers ample time during the view of the remarkable design. Confirmable from, A University of Tradition: The Spi rit of Purdue, while in terms of aesthetic value, the structure achieves great scoring in terms of points; however, the president of the Purdue and the university architect had to absorb certain amount of pressure and complaints directed to them due the hindrance notable in the project. Apparently, the project was Martin Jischke’s first project in the university. The eventual formation of a community organized committee to seek the way forward on the matter explains the vital

A Process of Ongoing Improvement - Essay Example The primary formal presentation of DBR was by Goldratt and Fox, however before that point by point presentation, it was first known in The Goal, and that is the place most experts likely first look into it. After going through the novel carefully or even casually, the reader may be left with the feeling that numerous enhancements were made, however not have an acceptable thought of precisely what happened when, and how they all nourished together to realize the progressions seen in the plant. This paper dissects the information introduced throughout the course of the story. In this manner, there are a few goals: The Goal is not difficult to peruse and comprehend which has made it prevalent with specialists. Since it puts the onlooker amidst Alex Rogers confused life at Unico, the spectator can perceive how the majority of the substances of a plant administrators life influence an individual's capacities to make the "right" choices. Consequently, it is an influential approach to help individuals without production experience comprehend these substances. With an advance like that, it is straightforward why the third amended release says "In excess of 3 million duplicates sold". Since most secondary school understudies have not accomplished a production environment direct, the book has been utilized within numerous colleges, and the writer has utilized it as a part of a propelled production course for 10 years. Over numerous readings, the writer started to recognize more insights about the plant's ability sprinkled all through the book. A cautious take a gander at the points of interest in the book has demonstrated supportive in understanding the progressions and their effect in the plant.

The Channel Tunnel Project Construction Essay

The Channel Tunnel Project Construction Essay Two centuries ago, in 1802, a French mining engineer called Albert Mathieu was the first one to propose a tunnel under the English Channel to link the UK and France. Since that time several proposals have been put forward however none of them could be realized due reasons such as lack of technology or the critical relationship between these two countries. In July 1985 a proposal submitted by the Channel Tunnel Group/France-Manche (CTG/F-M) beat those put forward by their four main competitors and was accepted. This proposal was amongst others more favoured by the British and French government due to the privately funded nature, financial robustness and technological simplicity. Scope of the Project The channel tunnel was project was completed over 7 years time, involving 15,000 workers at the peak of construction. The tunnelling commenced in 1988 and began to operate in 1994. Eleven tunnel boring machines were used on both sides of the channel to cut through the chalk marl and to construct 3 tunnels, 2 for rails and 1 for maintenance. The shuttle terminals are at Folkestone and Coquelles near Calais and the main aim for constructing such a massive tunnel of 32 (50km)miles length, of which 23.6 (30km )miles are underwater, was to allow people to travel between those countries in an unprecedented travel time of only 35 minutes. Main Participants The main participants were Channel Tunnel Group/France-Manche (CTG/F-M), which formed a new entity called Eurotunnel (ET), a bi-national company. ET was owned by banks and 10 other companies and is the owner and operator of the project for 65 years, until 2052. and client of the contractor Transmanche Link (TML). Design, construction and commissioning fell in the responsibility area of TML and commissioning of the project. An interesting sidenote is that both groups consisted of employees from France and the UK. This project is supervised by the Intergovernmental Commission (IGC), on behalf of both governments to ensure the Eurotunnels compliance with the Concession. This body was in charge of the reviewing design, procedures, specifications and in particular issues related to environment, operation and safety of the tunnel. The Maà ®tre dOeuvre, an independent Consulting engineer, has been appointed technical auditor and was reporting to ET, the IGC and the Banks. Technology Used Eleven tunnel boring machines (TBM) have been used in total on both, the French and the British sides, to work their way through the chalk marl stratum, which is between the gray chalk and glauconitic layer. ( See Figure XXX). On the English terminals 6 TBMs were operating while on the French side five TBMs were used. Due to the high pressure nature of the water which were present in the folded and faulted chalk on the French side, three special TBMs, namely Earth Pressure Balance machines (EPBM), had to be used. On the English side, simpler but faster open face TBMs started digging from the Shakespeare Cliff. On average the TBMs worked 873 m per month. In the best month it set a world record of 1,719m per month which yet has to be beaten. Project Life Cycle 1) Initiation April 1985 Promoters were formally invited by the French and UK government to submit scheme proposals for a fixed link between those countries -January 1986 Mandate awarded to the Channel Tunnel Group/France-Manche -Feb 1986 Treaty of Canterbury is signed allowing the project to go ahead Setup of IGC to supervise the project -April 1987 French Parliament allows the project 2) Planning Design and Financing Jan 1987 Design phase was relatively short as it was based on the 1975 project and the proposal which was submitted in 1985. Aug 1987 TML and 5 banks (Founder Shareholders) put initial equity of  £47 million (Equity 1) -Sep 1987 Loan syndication of  £6bn with the European Investment Bank (EIB) Oct 1987- Private placement of  £206m in shares with institutions (Equity 2) Nov 1987 Public Issue (Equity 3) worth  £750 million and  £5bn bank loan is agreed Nov 1990 Rights Issue (Equity 4) Second round of financing worth  £566 million Nov 1994 Rights Issue (Equity 5) Second round of financing worth  £566 million 3) Execution and Controlling June 1988 First tunnelling commenced in France Dec 1988 British TBMs start to drive towards France Dec 1990 Service tunnel breaks through under the sea linking the UK and France 4) Closure (Delivery) Dec 1993- Contractor TML hands tunnel over to client ET May 1994 The tunnel was formally opened by HM The Queen and President Mitterran -June 1994 First passenger train travelled through the tunnel beneath the English Channel, à ¢Ã¢â€š ¬Ã‚ ¢ A brief definition of the roles and responsibilities of the project sponsor and the project manager at each of the stages of the life cycle shown above. The project manager was appointed in the initiation phase after the concessioner agreement was signed. Separate project managers were appointed to manage the British side and French side; they were Atkins and Partners (UK) and Setec (France) respectively. During the initiation phase the project managers planned the project, agreeing on milestones and determining the tasks that would need sub-contracting. The project sponsors Eurotunnel justified the funding required and set up the success criteria. In the equity phase the project manager did not have a very big role. The optimistic plan to open the tunnel by May 1993 meant that the design phase was short with insufficient accuracy and detail. This had many repercussions and was the main contributor to the delays felt later on in the project. In this stage the project manger was managing the over all drive of the project and ensuring the design met the concessions specifications. Eurotunnel set the time, cost, and quality specifications and set all minimum constraints. All major changes made to the design had to be approved by the sponsor. In the Development phase the project manager had to make a variety of managerial decisions to maintain and bring the project back on the required time schedule. The project manger was also in charge of ensuring there was sufficient linking of tasks. The two teams met monthly to review progress and adapt schedules. Eurotunnel monitored the project progress from an objective point of view. Eurotunnel also reviewed and had final say on all major changes made to the design in this phase. In the Delivery phase the project manger and the sponsors review the project and decide whether the deliverables had been met. The contractors TML and the project managers handed over full responsibility of the channel tunnel to Euro-Tunnel who would have to fulfil the Concessions agreement for the rest of the duration in which they would run the Tunnel. à ¢Ã¢â€š ¬Ã‚ ¢ A statement of the ORIGINAL PROJECT OBJECTIVES: TIME The channel tunnel took 7 years to build. The first train carrying passengers and their cars journeyed to France on the 22nd December 1994. The initial plan has foreseen the tunnel to be ready on the 15th May 1993 therefore the work has been completed more than one and a half after schedule. COST The Channel tunnel is the largest privately funded project in history. It was clear from the beginning that the two governments would not get involved in the funding of the project as this was the only basis on which Margaret Thatcher, British Prime Minister, would accept the project. Funds have been raised through equity raising in capital markets and loan agreements. In total more than 200 banks, including the founder shareholder banks Natwest and Midlands in the UK and the French banks Credit Lyonnais, Banque Nationale de Paris, Banque Indosuez raised a total capital of  £4bn in various equity issues. The actual completion costs were at an 80% cost overrun in 1994 compared to the cost estimate of  £2600 compared by the contractor group TML in 1985. Underestimation of rolling stocks, changes in the fixed equipment work and terminals as well as the initially poor tunnelling process all contributed to the cost overrun. QUALITY As mentioned above an organizations such as Intergovernmental Commission(IGC) and Maà ®tre dOeuvre (MdO) was a form of engineering supervision employed by the Eurotunnel. The main task of this body was to monitor all activities on the project and write quarterly reports to keep government and banks updated whether the project was executed in accordance with the requirements of the Concession and the quality assurance standards established by TML. To achieve the required quality of standards a classification system has been used on the management plane to make the whole process more flexible by assessing and prioritizing the tasks. Although quality requirements were of equal importance for every single task, the management style was categorized in 3 different levels according to complexity, maturity of the technology and overall impact of the task.

Comparing The Chorus of Sophocles Antigone and Americas News Channels :: Comparison Compare Contrast Essays

Comparing The Chorus of Sophocles' Antigone and America's News Channels The Greek Chorus is very similar to America's news channels because it brings the people the news in a way that they can understand it. The play Antigone by Sophocles is a tragic drama structured around the argument between a king and two sisters about the burial of their brother. Antigone can be compared to the conflict surrounding granting illegal immigrants amnesty. The Chorus is a group of people who provide background information, interpret the information, and relate it to human nature. The Chorus in Antigone tells the pros and cons of both sides of the story and adds important information needed to fully understand the conflict. The Greek Chorus serves the same functions as American news channels in the twenty-first century. Both a news channel and a Chorus provide background information during the telling of a story. After Antigone and Ismene converse about the burial of their brother, the chorus steps in setting the mood and providing background information. "Now the long blade of the sun, lying level east to west, touches with glory Thebes of Seven Gates. Open, Unlidded" (Sophocles 314). This shows that at that point in the play, it is morning and the sun has risen. It sets the tone and describes the setting for the next scene. On a news channel, background information is also provided. "Over eleven million illegal immigrants are already living in America" (Buchanan). This tells the viewer how serious the topic is by using such large numbers and giving facts. This statement will also-strike a nerve with many people because it is saying that 11 million people have committed the same crime their country. As you can see, there is a great similarity between the Greek and American way of providing b ackground information. American news channels and Greek Choruses both interpret information for viewers, so they can better understand different points of view. It is believed by the Greeks that Creon has a divine right to do whatever he wants. "If that is your will, Creon son of Menoikeus, You have the right to enforce it: we are yours" (Sophocles 316). Creon can do what he wants because the people will have to support his ideas because he is the great and powerful king with a divine right to rule.
