Importance Of Civil Engineering in Britain

Importance Of Civil Engineering in Britain Civil Engineering is the key to many of the issues affecting our daily lives. Civil engineers solve most problems and make our live easy and enjoyable. Civil engineering covers several specialized sectors including: buildings of all kinds as well as transport and communications infrastructure, production, storage and distribution of electricity gas and water. Most everything civil engineers do affects our daily lives in many ways. The operation of the infrastructure that surrounds us is the foundation of our society. This infrastructure includes roads, airports, railroads, buildings, bridges, water and wastewater treatment plants, sewers, drainage, flood control, water supply, landfills, and many other facilities. All these are the jobs for Civil Engineers. This essay is about importance of civil engineering in Britain and roles of civil engineering in Britain. I will do this by explaining water sewers, buildings, roads, stadiums development, wastewater treatment plants, energy development, york eco depot, airports, railroads, bridges and, sewers, drainage, flood control and water supply. Civil Engineers saved time, money and resources by demolishing an old seven-storey building in Londons Buckingham Palace Road and replacing it with a new building that re-used the foundation of the original building. This technique reduced construction risks associated digging new foundations in London clay near the Circle and District Underground line. If more new piles had simply been installed between existing ones this would have restricted the future development of the site. Great care was taken to prevent water produced during drilling from swelling the clay and reducing the strength of the foundations. Other challenges included testing the structural integrity of the original piles and identifying their exact location as the original pen and ink drawings only showed the building as designed, not as it was actually constructed. The essential engineering work to ease congestion around Heathrow Airport would have caused chaos along a 23km stretch of the M25. M25 is regarded as on of the busiest motorway in Europe, visit [http://www.bbcel.co.uk/news/631_key-milestone-complete-on-m25-junction-16-23 ]. As well as ensuring construction work did not create traffic jams engineers also had to find clever ways of widening the road within existing highway boundaries and without using any new land. Getting land from the motor ways central reservations as well as the hard shoulders and verges of the motor ways, the civil engineers increased Junctions 12 to 14 from four lanes to five lanes as well the Junction 15 from four lanes to six. Around ninety percentage of material used for this construction was recovered from the site and recycled. This technique not just reduced the congestion but also transport needed for the construction. On the night, when the natural awareness in so small and traffic queues are so small, the line closures are scheduled. This project was completed in 2005 before the time allocated without being seen the traffice congestions expected before the project has been started. Engineers worked together to define unique characteristics of the Wembley Stadium and create a new English national football stadium that just looks like the original old building. While most modern stadium are orientated North-South so that the players seen well on afternoon sun, this new stadium is orientated East-West, just like the original Wembley (thanks to knowledge of the civil engineers). Visit http://www.wembleystadium.com/buildingwembley for more information regarding this project. On sunny days the South side of the roof is retracted so the whole pitch is in sunlight. This avoids valuable seconds of play being lost to broadcasters as television cameras adjust from bright sun to shadow. The iconic arch spans 315m, are visible for over 20km, carries 70% of the roof load and removes the need for any structural columns. This means that, unlike the old stadium, all 90,000 seats has unobstructed views of the pitch. [http://www.wembleystadium.com/buildingwembley] To solve the crisis Hampshire and its partners created an action plan to reduce waste, increase composting and recycling, support anaerobic digestion, adopt recovery technologies and create up to five new facilities to process up to 200,000 tones of waste annually. The new Chineham Energy Recovery Facility is exceptional because engineers altered a standard building format to fit the small 1.4-hectare site of a former Basingstoke incinerator. The facility produces up to 8MW of power of which 1.25MW is used to operates the plant. The remaining 6.75MW is sufficient to supply 10,000 homes with electricity each year. The building is partly clad in light-reactive coated aluminum that changes color depending on light levels and weather to appear grey, blue or purple. Semi-opaque polycarbonate cladding allows natural light into the building and reduces electricity use. The tipping hall has a living roof covered with plants that change color seasonally and require no maintenance.

Beddington Zero Energy Development, (BedZED) is regarded as an eye-catching and affordable housing community in South East England. Civil engineers worked to reduce the energy demands of 100 homes and 2,500m2 of commercial space, according to http://www.bioregional.com/what-we-do/our-work/bedzed. The civil engineers reduced the demand for energy with renewable resources including passive solar heating and wood-fuelled combined heat and power. These energy sources resulted by reducing fuel carbon dioxide emissions into the atmosphere to as well fossil energy development to zero. While BedZEDs tenants are assured an efficient energy lifestyles by using the techniques used by engineers to reduce the amount of energy they require. Visit www.bioregional.com for more information regarding this project. The civil engineers used their to help City of York Council to move its department for housing, waste and roads from an expensive to an attractive new cheaper building. The civil engineers knowledge resulted in using a technique that maximizes natural light and ventilation by using sensors that detect high temperature, rain or high wind and open and close windows accordingly. Rainfalls from the roof of the building is collected in what is known as the underground tanks and used to wash vehicles. This resulted by reducing water consumption around fifty percentage. The warehouse construction also reduces energy use by up to seventy-six percentages and the Carbon Dioxide (CO2) emissions by up to one hundred and fifty five tones annually if compared when building to a traditionally built, air-conditioned office of the same size. The warehouse also includes an Interpretation Room that could be used for education of the community in the City of York Council.

My conclusion is that the water we drink, the pavement we drive on, the air we breathe are the work of civil and environmental engineers literally surrounds us all. Transport systems join our communities together. Road, rail, air and sea networks span the world. All these are the work for civil engineers. Civil Engineers help us trade, travel, exchange ideas and information, and gain employment, healthcare and education. Our civilization is developing, but so too is our demand for electricity. Civil engineers are committed to protecting our natural resources, designing structures that use as little energy as possible. When it comes to providing energy for the entire planet, engineers are using nature to meet the needs of today and tomorrow. We should be proud of our civilization today, and its many great achievements. By applying the latest technologies, civil engineers can save structures and monuments from the distant past so that they can still be enjoyed well into the future. Civil engineers are using designs and materials that will protect our natural and cultural heritage for future generations. The civil engineering knowledge cannot be regarded as a new subject. It has been around for so many hundred years back to the Romans (for their ancient Roman civilization), Egyptians (best known for their building of the pyramids) and Mayans (the Mayans are people from America that have a history or around three thousand years) who built great civilizations before us, our civilization relies more than ever on the civil engineers whom the work on all the environment in and around us, such as the road, the bridges, the libraries, the buses, the trains, the aero planes, the water we consume in our every day life, the toilets that we use, the cars we drive, the houses we sleep, the shelters that we cover from the cold and hot and the many more things that we use in our daily life without them the life would now have been as the one we have today.

Henritta Lacks Paper

The â€Å"immortal Life of Henrietta Lacks† tells a fascinating story of a sample of cells that forever changed the landscape of scientific research. The book tells the story of the family related to Henrietta Lacks. The book touches on the doctor and patient relationship. Henrietta Lacks cells (â€Å"also known as HeLa†) became involved in bringing informed consent to the research field. The patient didn’t always know what the doctor was doing to them. The doctor should always inform the subject of what they are doing and the purpose before the subject can consent.Informed consent is a legal procedure to ensure that a patient or client knows all of the risks and costs involved in a treatment. Up to 1947, the thought of informed consent hadn’t even crossed anyone’s mind. In 1947, the Nuremberg trials were held wherein 7 Nazi scientist were convicted of conducting unthinkable tests on Jewish subjects. This marked the first time informed consent enter ed anyone’s conscience. It still wasn’t law. It was just an ethical code which had no legal bindings.Then ten years later, when scientist Southman was injecting HeLa into patients’ bodies without telling them how dangerous it was and some of them died and an investigation ensued. This caused a division between people and doctors. Some doctors decided against informed consent because it would interfere with their research practices. There was great fear amongst the African American community about doctors kidnapping them and doing all sorts of wild tests on them. There was some truth to these apprehensions.Doctors would regularly test on African Americans with consent. In the book, when the doctors ask Day if they can do an autopsy they didn’t give him the whole details. But that wasn’t the rule back in those times. The problem with explaining the details to people is that they simply wouldn’t understand what the doctor was talking about. The patient had no clue what a cell was. So rather than explain what they were doing in detail they would just tell that it would benefit their children. This is wrong, doctors shouldn’t take the easy way out.They should inform their patients of the extent of their intentions. The doctors would prey on the black community’s ignorance in the medical field. The doctors should have just told them their intentions. In today’s atmosphere, the rights of patients are more protected than they were in the 1950s. Doctors now have a legal and ethical duty to inform patients in all areas. Therefore, more information is available to patients so they are able to make intelligent and informed decisions on their medical treatment and use of their tissue, cells or organs.

Aristotle Virtue Ethics Essay

One basic notion in Aristotelian ethics that occupies a central significance is Aristotle’s belief in the role of man’s activities in order for one to acquire ethical knowledge. That is, for one to become virtuous or to obtain virtues one should not merely confine himself to mere studying of these virtues but rather one should, more importantly, actualize this knowledge of the virtues. Thus, for one to become good, one should do good. Aristotle further stretches his ideas by proposing the doctrine of the mean. The essence of this doctrine dwells on the basic precept that one ought to avoid the extremes and, instead, settle for the â€Å"mean†. The actions of men, more specifically, ought to be framed upon the â€Å"mean† which is the virtue. For example, the virtue of courage rests on the mean between two extremes: cowardice or the â€Å"lack† of courage, and rashness or the â€Å"excess† in courage. It can easily be observed that Aristotle suggests that one should live a life that does not border on the things that are on the â€Å"most† and the â€Å"least† levels. For example, if I were to follow Aristotle’s ethics I should always see to it that I should consistently draw myself towards the middle value and avoid slanting towards cowardice and excess. All this could have been very well except for one small thing that I cannot seem to fully comprehend. How is it possible for one to ascertain that one is actually taking the middle path? Or how is it possible for one to know that this or that is the middle value or is the virtuous action? Perhaps the key in having an understanding to the notion of the â€Å"mean† is that one should act. That is, as I continually have these ideas as to what I must do when faced with an ethical situation or, at the least, an ordinary situation, I should nonetheless take the course of action so that I will be able to obtain a qualitative understanding that what I am doing is the â€Å"excess†. On the other hand, I will be having quite a rough time in acquiring the understanding as to whether the action that I am doing is virtuous if all that I do is to theorize and never let my theory be put into practice. Aristotle’s virtue ethics reminds me of Plato’s conception of ethics. For the most part of the Republic, Plato attempts to arrive at a conception of a just life by centering on the notion that the just life or that which is good is better than living a life molded on an evil framework and one which prompts individuals to act in an evil manner. At the onset of the Republic’s Book II, a conception of the idea of â€Å"justice† is advanced as the working of an individual in accordance to the role in which one is best suited as well as the belief for non-interference in the activities of others. In essence, this principle is closely related to Plato’s perspective on acting in accordance to one’s nature or intrinsic being which results to the state or condition of being â€Å"just† or acting justly once the individual acts in line to his very nature. Otherwise, if one begins to act beyond what his nature prescribes, then the individual begins to act in an unjust manner thereby resulting to â€Å"evil† actions (Plato and Kamtekar). While Aristotle insists that one should put into action the thought that one may have so as to have an understanding of the middle value that should be taken, Plato, on the other hand, suggests that one should simply go by with one’s nature so as not to be â€Å"evil†. If I were to choose which ethical precept would be better or would fit me best, I would rather be inclined to adopt Aristotle’s virtue ethics over the other because it offers me a chance to actualize myself through my actions and be guided accordingly. Whereas for Plato, what I am seeing is that I should get to know my self first before I act so that I can be good. But this cannot be met easily essentially because I find it quite difficult to know myself if I would not act first. In the light, if all the students in a certain class would build up a virtue like that of Aristotle’s point of view, the achievement of an environment which is formidably that built on the concept of philosophical and tremendously beneficial notions in life, the attainment of the virtue of goodness is towering in the highest hopes—although it eventually does not also undermine the concept of realism. Apparently, many may not stick on this kind of perception and ought to think that it is certainly not possible to achieve a life which is way beyond the bounds of a â€Å"not-so-good† life for that instance, but with the maximum height of human rationality, such may be given enough credit for the philosophers who believed in a life where â€Å"goodness comes in deeds† (Lannstrom).

Linear Parent Functions (Algebra Help)

Each type of algebra function is its own family and possesses unique traits. If you want to understand the characteristics of each family, study its parent function, a template of domain and range that extends to other members of the family. The most basic parent function is the linear parent function. Algebra Function Basics In the phrase algebra functions, a function is a set of data that has one distinct output (y) for each input (x). A function also describes the relationship between inputs (x) and outputs (y). As a testament to the various patterns between x and y, several types of functions exist: LinearAbsolute valueQuadraticExponentialTrigonometricRationalLogarithmic Linear Parent Function Characteristics In algebra, a linear equation is one that contains two variables and can be plotted on a graph as a straight line. Key common points of linear parent functions include the fact that the: Equation is y xDomain and range are real numbersSlope, or rate of change, is constant. You can see the physical representation of a linear parent function on a graph of  y  Ã‚  x. Linear Function Flips, Shifts, and Other Tricks Family members have common and contrasting attributes. If your dad has a big nose, for example, then you probably have one as well. Nonetheless, just as you are different from your parents, so is a subsequent function different from its parent. For the linear parent functions below, note that any changes to the equation will alter the graph. Vertical shifts: y x1 The graph shifts up 1 unit. y x-4 The graph shifts down 4 units. Changes in steepness: y 3x The graph becomes steeper. y  ½x The graph becomes flatter. Negative influence: y The graph flips and slopes downward, instead of upward. (This is also called a negative slope.)
