What it takes to be a superior human being in Confucianism Essay
What it takes to be a superior human being in Confucianism - Essay Example According to Confucius, a superior human being listens to the critique with an evaluative attitude and does not turn a deaf ear to something that does not sound pleasing. Superior human beings search for truth and do what is proper in a particular situation at hand. Superior human beings make unbiased decisions and accordingly, do not have anything to expect from others. This is the reason why they always remain satisfied. â€Å"The superior man wouldn't recommend or promote a person based only on his words, nor would he ignore a man's words because of his behavior†. They do not get involved in controversies against other people and remain calm and quiet. Confucius held the opinion that individual’s inability to perceive and handle the reality is the fundamental cause of social disorder. Quite often, people call one another with wrong names. When things are not called by their proper names, this promotes social disorder. In Confucianism, a superior human being is the one who calls things by their proper names because calling things by incorrect names does not let the language remain consistent with the truth. This keeps the affairs from being carried on to success. When this happens, music and other proprieties can not flourish which in turn makes the punishments awarded improperly. As a result of this, people become troubled and can not work. Thus, a superior human being necessarily calls things by their proper names and makes sure that his speech is carried out appropriately.

War and Technology Essay Example | Topics and Well Written Essays - 1750 words
War and Technology - Essay Example During World War One, military officials realized the importance of having up to date weapons to win wars (Stewart 2001)2. During this period, armies used advanced weapons recognized as second generation warfare and realized that machinery and weapons are used to conquer and win battles and the only importance of military officials is limited to occupying the conquered areas. 1Harris, Brice F. America, Technology and Strategic Culture: A Clausewitzian Assessment. London: Routledge, 2009. Internet resource. 2Neil, Stewart. The Changing Nature of Warfare, 1700-1945. London: Hodder & Stoughton, 2001. Print. During this period armies even realized the importance of transportation as these vehicles were used to transport men and machinery from one end to another. These improvements in technology clearly defined that to gain victory in war; you have to be sound technologically at both the operative and the tactical bases. The belief of technological soundness being the determinant o victory of war was clearly visible in different wars such as the Cold War and Current Wars that take place every now and then. Body After WWII, major nations throughout the earth started developing the technological side of their defense, they started developing and acquiring new kinds of air shuttles, sea transport and weapon, new form of larger missiles and bombs and machinery that is used while nation’s army is fighting in the land (Melko 2001)3. The continuous up gradation of the technological side led to the development of military aircrafts and air transports which had higher degree of accuracy and speed, researchers even developed new forms of surveillance systems to gain higher degree of accuracy during the process of acquiring information, for this purpose GPS systems came into existence. These developments in technological advancements were recognized as 3GW (Third Generation Warfare), these developments were utilized during the period of WWII and during Gulf War th at took place between Iraq and US and later even in different attacks conducted on Iraq starting from 2003 till present date. These wars clearly exhibited that those countries that were able to accept and create technological advancements are the victorious ones. 3Mathew, Melko. General War Among Great Powers in World History. Lewiston, N.Y: Edwin Mellen Press, 2001. Print. Advanced Technology in Operational Level While creating a strategy before going to war, both the tactical as well as the operational bases of the war are taken into consideration and special importance is given to the technological aspect of these two bases. According to Giulio Douhet, one of the best strategies implemented is the use of air power to destroy the opponent civil population’s willingness to fight (Douhet 2010)4. This strategy was implemented in different wars, for example: during the period of WWI, this strategy was implemented by the German strategists while attacking London and NATO forc es even used the same strategy while attacking Kosovo. This strategic move increases the accuracy at which the war targets are attacked, thus this strategy obtains the optimum result while keeping the collateral losses at the lower end. Advancement in technology has been accepted as morally correct as these advancements increases the probability of armies gaining the accurate intelligence about the legal targets that need to be

Corrosion, Repair and Maintenance of Structures Essay Example for Free
Corrosion, Repair and Maintenance of Structures Essay Chapter 1.0 Introduction In many places around the world, there are structures that have existed for a long time and either they are still being used or they are simply left there standing with no use at all to the public. For that reason, these structures that are no longer being used must be rehabilitated in order for them to be re-used in some way. When pertaining to structures, to rehabilitate means ‘to restore, to repair, to rescue from a state of corrosion’. The idea of rehabilitation came after the World War II when old buildings were starting to show damage through time or damage from human intervention. The easiest way to fix them was to restore them. That process today is very widely used and is a very familiar process, which applies to almost every structure on earthâ€â€from structures that need to be repaired to structures that need to have a completely different look or structures that need to expand. It can also be applied on structures that need to be strengthened in order to prolong its life for another set of years. Rehabilitation of structures, as a process, can save time, money and work. That is because there is no need for the demolition of an already existing structure and building again from scratch. Simply put, rehabilitation means that some changes or improvements need to be made. This process also saves space since there is no need for a new area in order to build a new structure.            In this paper, I am going to divide this process into three stages. The first stage is the corrosion, where I am going to explain all the factors that lead to corrosion of structures and how it affects them. The second stage is the part of repairing a structure after it has undergone corrosion. In this stage, I will mention ideas and ways that have been developed through the years which can be applied to existing structures that have been affected by corrosion. The third and final stage that will be discussed in this paper are the ways on how to maintain a structure and how to prevent further deterioration after repair in order to minimise its cost efficiency. Chapter 2.0 Corrosion Factors Introduction Corrosion is caused by a lot of factors and it often results to the failure of a structure. All these factors have to be studied in order to prevent structure failures. Corrosion, most of the time, is caused by extreme weather conditions but it is not the only factor that causes corrosion and it is also not the main cause of structure failures. By analysing corrosion and explaining how it happens, we can separate it in different areas. Factors of Corrosion Corrosion depends on many factors which we will focus on such as material, environment, stress, temperature and time factors. These factors are dependent and interconnected with each other. Material Factor            The material factor has to do with the materials that are used for the structure. Materials also has a connection with the environment where the structure is put up (i.e. weather, temperature, moisture, etc.), which we will discuss later in this report. The material factor is important as it all starts from the selection and planning before being able to build the structure. The selection process is divided into three stages.            The first one is listing the requirements taking into consideration the strength and other properties of the material. The second stage is choosing the most convenient material focusing on its technical properties and evaluating them. The last stage is based on the economical factor, which means that after going through the first two stages, we came up with a variety of materials and the only thing left to do is to choose the cheapest and most suitable material for the structure. The final process has to do with the fact that the structure is for repair and that redesigning the whole structure is not easy which means that more attention should be given on delivery time and completion. Environmental factor Environment is a crucial factor in corrosion of materials. This is caused by a lot of factors and the main factor that needs to be considered is that the materials have a tendency to expand or shrink depending on the changes in the temperature (Table 2 below shows some data on expansion of different materials) and also in areas where the weather changes from rainy to dry or vice versa in a short span of time. Moreover, water as a factor greatly affects a structure because it can penetrate in the material and cause it to crack. If the material is steel, its exposure to water will cause it to rust and the rust can spread and also affect other materials.            Another factor to be considered is moisture that can be caused by rain, condensation, leakage from pipes or drains and rising damp. For the underwater structures and especially for those in salty waters (i.e. sea) more problems arise because salt can accelerate the phases of corrosion, and due to that, extra care has to be provided in choosing the materials. Wind also has to be considered. In some areas, winds can prove to be very strong. And strong wind coupled with the effects of some other factors can cause extreme deterioration also because it can bring dust and dirt, which can penetrate materials causing discolouration and corrosion.            Finally, pollution is another factor that contributes to the environmental corrosion of a structure. As we know, atmospheric pollution can be transferred to the ground in the form of acid rain. This acid rain can react with the materials that were used for the structure and can cause its rapid deterioration. Regular cleaning of the structure would be helpful in preventing any unwanted deterioration. Stress factor Stress connects and interacts mostly with the environmental and the temperature factors. Changes in temperature followed by expansion and contraction causes cracks on structure which can result in structure failure in a worst case scenario. In some situations, the structure fails without showing external deformation making it hard to avoid. Even though cracks cannot be seen by the human eye, there are multiple cracks attacking the materials under the surfaces of a structure. These cracks in microstructures can form intergranular or transgranular morphology. These kinds of cracks can cause a big problem because they are difficult to detect. The photo on the right is shows an intergranular SCC (Stress Corrosion Cracking) following the grain boundaries. Problems like this can cause an unpredictable failure of the structure resulting in loss of materials. Temperature factor Changes in local temperature can affect the stability of a structure in a major way because of the expansion and contraction that the structure is being exposed to. Usually materials tend to contract during low temperatures and expand during high temperatures which can cause small but dangerous cracks that can further lead to the failure of the structure. In order to prevent such a disaster from happening, the most common recourse is to select proper materials that can adapt to the environment where the structure will be erected. The temperature factor, of course, depends on the environment factor and the stress factor that we talked about earlier in the report. Time factor Time in corrosion is a very big issue. Time is the factor that produces all the problems and is the one that makes all the others affect the structure. Without time, corrosion would not happen. Of course, time is not the only factor that causes corrosion as we have already discussed. The ones that have a clear connection with the time factor is the environment, temperature and stress factor.            From all that were mentioned, one final but very important factor must be taken into consideration. Corrosion does not have the same effects on all materials; different type of material will have a different kind of reaction with the various factors. Types of Corrosion Affecting Structures First of all, let us consider that we have a reinforced concrete structure. The mild steel that is used for this structure to reinforce the concrete creates a layer on its surface in order to keep it in a passive state. This layer is caused by the alkalinity of the concrete. Therefore, the corrosion that will affect the structure will be caused by the steel that is reinforcing the concrete, and there are three types of such based on the steel corrosion. These are Chloride Contamination, the Patch Accelerated Corrosion and Carbonation. Chloride Contamination The presence of chloride ions in the atmosphere, which are formed usually where structures are exposed to de-icing salts (used to maintain safe transportation during winter time) or to a marine environment, can cause the destruction of the protective oxide layer of the reinforcing steel and lead to its corrosion. Patch Accelerated Corrosion This type of corrosion is either known to the public as the â€Å"Ring Anode Corrosion†or the â€Å"Halo Effect†. This phenomenon is often detected on concrete restoration projects where there is presence of concrete spalling on previous patch repairs. It is most commonly found on the exterior of the structure and is caused by its exposure to freeze and thaw cycles. Carbonation This process is very similar to Chloride Contamination. A state called carbonation, it is caused by the reaction of carbon dioxide within calcium hydroxide in the presence of water. It can cause the loss of alkalinity in concrete. This loss of alkalinity that happens to the surrounding concrete of the steel can cause the destruction of the oxide layer that is protecting the reinforcing steel. This kind of corrosion is a big threat to old buildings. Areas where Corrosion Applies Corrosion can be found in different kinds of structures. One of them is the bridges where there can be corrosion on the reinforced concrete caused by the presence of de-icing salts or by their exposure to marine environments. Parking garages are also exposed to corrosion, and this can be caused again by the presence of de-icing salts transferred there by the parked cars. Of course, buildings are exposed to corrosion too, and it most likely applies on spandrel beams, columns and balconies. The types of corrosion usually found on these structures are the types of corrosion that were discussed earlier, namely, chloride contamination and carbonation, which can also be caused by exposure to sea spay usually to buildings close to the sea, and also through contact with atmospheric carbon dioxide. Another area where corrosion can be applied are the marine structures, like concrete piers and wharfs since they are exposed to chloride contaminated salt water and airborne chlorides along with high temperatures and high humidity. Deterioration of Concrete in General Concrete, like other materials deteriorate due to internal and external forces causing concrete failure. Other causes are water infiltration, carbonation, corrosion of reinforcing steel, shrinkage, drying, thermal contraction and poor placement practices. From that, water can cause a big problem to concrete since it can penetrate and freeze during low temperatures. This can apply extreme pressure to concrete and make it weak and finally cause it to fail. Also, water carries chemicals like acids, sulphates or chlorides that can attack concrete and corrode the reinforcing steel inside it and expand the corrosion from inside to outside. Another cause is carbonation, where water from rain can be combined with carbon dioxide in air and after some time infiltrate concrete and react with the calcium hydroxide and create calcium carbonate which can decrease the concretes pH level and attack the surrounding layer of the reinforced steel. This can cause corrosion of the steel since it is no longer protected and this as we said before can affect concrete as well because of the presence of moisture. Deterioration of Structures and Service Life The deterioration of structures is a process that comes in stages and from that, we can point out the starting stages of the actual corrosion which is the concrete cracking and the excessive deflection. This can result in a reinforced concrete failure due to loss of structural strength. Service Life of a Structure Each structure has its own service life. This service life is said to be the time period that when ended will need human intervention such as conducting repairs, strengthening, maintenance or rehabilitation. By knowing the service life of a structure, we can determine the time when such actions will be required. The service life of a structure is separated into four stages. The first of the four phases is the time period from completion of building the structure to its corrosion initiation. The second phase starts after the corrosion initiation and until corrosion induced cracking. In the third phase, we have the time period from the concrete cracking up to the excessive deflection of the reinforced concrete members. As a fourth and final phase, it is the time from the loss of serviceability to the final collapse of the structure, which means that the structure arrived to a point where it had lost its flexural and shear strength. By determining the corrosion stage of the structure, its service life can be made known and as result, the phase in which the structure is currently experiencing at the moment can be identified. Furthermore, the time period of each of the four phases of the service life of a structure can be determined once a performance-based assessment criterion is established. The period of each phase can be calculated with the help of the following formula:            S (t) = Structural Response (Load Effect)            L (t) = Acceptable Limit for Structural Response (Structural Resistance) By knowing the time periods of each of the four phases of the service life of a structure, a probable failure can be determined by using the following formula:            pf (t) = Probability of an event Deterioration Stages of a Structure            Let us go back through to the stages of deterioration of a structure and discuss it. First we have the concrete cracking which comes at the end of the second phase of the service life of a structure and is after the initiation of reinforcement corrosion. So, after the initiation of corrosion, some rust is produced on the reinforcement. That covers more space than the initiation and as a result, some pressure propagates on the surrounding concrete which by itself cannot take the pressure since it exceeds its tensile capacity and starts cracking.        Furthermore, after the concrete cracking and at the end of phase three of the service life of a structure, the excessive deflection comes which is restrained within an acceptable limit. After the end of the fourth phase, we have the loss of strength of the structure which can lead to a structure failure. In that stage the corrosion on the reinforcement reduces the strength of the RC structure and results to a break at the critical cross section of a structural member. Deterioration of Strength There are two different ways of determining the strength deterioration of an RC structure, namely, the destructive load test and the non-destructive measurement of corrosion current density. Both of those methods can be used in the laboratory in order to measure the strength deterioration of a structure, but in practice and on the field, it can only be measured based on the reduction of the cross sectional area of the reinforcement bars. Deterioration of Stiffness Finding the stiffness deterioration of RC structural members is very important for the deterioration of the structure as a whole system where the load redistribution and the failure mode both depend on the stiffness of its members. Rate of Deterioration The rate of strength and stiffness deterioration is different since the stiffness is deteriorating much more severely than the strength. This is based on the fact that stiffness is measuring mechanical properties related to geometry and the cross sections of a structure way more than strength does. Factors that are related to corrosion and can affect the geometry of a structure are concrete cracking, delamination and debonding. After all those factors, and once the corrosion actively propagates, it results to a severe increase of deflection. Then again, deterioration of strength is not that affected from those factors which can only damage tensile sections of RC members.
This Experiment Marcet Boiler Engineering Essay
This Experiment Marcet Boiler Engineering Essay In This experiment a Marcet boiler was used to conduct the relationship between a saturated pressure and temperature of water in the range of 0-14 bar indicating in the gauge and also to determine the temperature of a body when being heated or cooled. When the temperature increases pressure also increases in this case the relationship between pressure and temperature is directly proportional. Assumption was made that the temperature is uniform throughout the boiler and the outside surface temperature of the boiler is the same as the steam temperature. Theoretically, the values from the steam table should almost be the same with the recorded values. In this case, if the values are not the same then this is due to error that was made in the experiment. The experiment was performed carefully and all procedure was followed to get accurate result. First of all the startup procedure is to fill water in Marcet boiler and the water level is half of the boilers height. Then the supply switch was turned on. It is important to remove the air in the boiler in this case the valve would be open from the start up of the experiment When the temperature increases to 100Â °C, the steam is allowed to come out from the valve for few seconds and close the valve. Record the steam temperature and pressure reaches 14 bars. Introduction Thermodynamics is the study of heat and in relation in other form of work and energy between a system and its surrounding; in this case the property in the system will change. Generally ideal gas obeys the equation of state which is showed below. PV= When energy is increased in the water .the molecules in the water that is increasing will enable the molecules to escape from the surface until it is in equilibrium (boiling point). The state of equilibrium depends on the pressure in the surface of the water. When the pressure is low it is easier for the molecules to leave the water with less energy. The Marcet boiler is used to investigate the relationship pressure and temperature in saturated steam for comparison with the steam table .the experiment slope (dT/dp) is obtained water at saturated temperature Theory The Marcet boiler is used to investigate the between pressure and temperature of saturated steam, in equilibrium with water, at all pressures between atmospheric and a 14bar An ideal gas can be characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them may be deduced from kinetic theory and is called the Ideal Gas law. The ideal gas law was originally determined empirically and is simply. and hf + hfg = hg Æ’Å ¾ hf as vg >> vf In which, vf = specific volume of saturated liquid vg = specific volume of saturated vapor hf = enthalpy of saturated liquid hg = enthalpy of saturated vapor hfg = latent heat of vaporization Equipment Procedure Fill up water half the height of the boiler Ensure the valve is opened Connect the boiler to the electrical switch The boiler is heated up to 100Â °c and the steam will come out of the open valve Close the valve after 1 minutes to ensure that the air in the boiler is out and continues heating When the pressure start rising , start the stop watch Record all the temperature readings at different pressure with time Pressure must not exceed 14 bar Discussion The theory can be compared with the experiment where pressure and temperature are directly proportional to each other When a water is heated in a container to a boiling point the tempreture increases and presussre also increase in the case where the steam is closed in a cylinder, Their will be internal pressure in the container and also internal forces. it is shown in the graph that tempreture is relatively proportional to pressure In the table error was zero because the decreasing tempreture of the boiler was not noted down therefore erro is unknown . assuming the decreasing tempreture is considered the the error percentage would now exceed 10% because the experiment was done in a closed system so no amount of volume will escape It was important to remove the air from the boiler to avoid flaws of readings . Marcet boiler is used in plant steam industries, power plant, cooking utensil and so on Conclusion in the experiment, it shows from the table and theory that temperature and pressure is relatively proportional in balance with water Disgracing some negligible faults, this experiment can be consider successful, to improve the result of the experiment, it should be carried out at room temperature switching off all the air-conditions, and also by repeating the experiment and taking the average value. If some insulation were kept on theMarcet boiler to reduce heat loss, the experiment could be more accurate

The Consequence of Marriage Essay -- Theatre, Shakespeare
The Consequence of Marriage William Shakespeare has always been an avid supporter of love as the basis of marriage. Nearly all of his plays support that: Romeo & Juliet, Much Ado about Nothing, and even more notably, A Mid Summer’s Nights Dream. Bernard Murstein noted in his book, Love, Sex and Marriage Through the ages, that â€Å"the young should marry whom they choose and that they not bow to parental wishes†(181). Shakespeare’s tragic Othello reminds that parents are there to guide their children onto the right path towards a brighter future, and is a cautionary tale about the potential implications of a quick or thoughtless marriage that generally end his plays. The ramifications of a marriage outside of social rank and race along with the general social consequences are highlighted to show that marriage is more than just an â€Å"I do†at the altar, and is to be avoided. When viewing Shakespeare’s plays in the context of the time period it is obvious that Shakespeare was more than a storyteller. His commentary was directed at the upper tier of society and addressed the need for convention to be followed. At the same time, he had to be sure that his commentary was acceptable or subtle enough so as not to offend his sponsors. In some of Shakespeare’s better known plays, he teaches that the course of true love never runs smooth, and marriages should not be expected to run smoothly either. Societal expectations of the time were that a woman would marry whomever the male head of the household chose for her. Men, on the other hand, were free to pursue anyone they wanted and arrange their own marriages, with an eye to strategic coupling of social status and finances (Gies 256). Romeo and Juliet showed the importance of parental approval ... ...ve for Desdemona is easily corrupt due to his own insecurities, and in the end, Othello’s demise is no fault but his own. He is the man and could have said no to Desdemona’s proposal of marriage, and prevented the entire debacle. The self sacrifice that he made would have mirrored the sacrifice that Elizabeth made to keep the peace in her country and build it to one of the greatest nations the world has seen.

Mimosa :: essays research papers
Separation from their original home was one of the many past events that caused tensions and turmoil between a father and his two daughters. While each individuals thoughts about each other fluxuated between both positive and negative, one thing remained constant through out the progression of the poem, the ever enduring presence of religion, faith and its beliefs. Religion has always had a place in the life of Vito and his family, he had his own ways of using his faith to comfort himself as well as his own visions on what a heaven would be to him, while his daughter also held a strong faith in religion. Just as the weak Mimosa plant needs support to grow or face death, each of Vito’s daughters , especially Lucia, has attached themselves to a faith, a religion to support and help themselves through life. Vito like many, have found a place for his faith. He believed that a true heaven would be back in his homeland, back in the garden that he cared for so dearly. This garden in fact acted like his own garden of Eden. For his character was like that of the tender Mimosa plant, which when faced with the slightest touch or trouble from an outside source, would recoil its leaves and take a defense position close to the garden that it grew within. Vito would retreat to this garden to escape the troubles of the outside world when they became unbearable. He describes the garden to us as; “The garden that kept them little children even as adults;'; This could be taken as that it did not actually affect Vito physically young but rather it altered him mentally. He would become like Adam and Eve before evil and like that of a young child, all ignorant of all troubles. Complexity and all other dilemma’s that plagued their lives. So in this garden he would escape his troubles through the means of ignoring them and not acknowledging their existence and thus a bit closer to peace, and less degrees of separation between himself and his God. Â Â Â Â Â Though his daughters once also joined him in his “light';, in essence his garden, it is said that his daughter, Lucia (an cleaver metaphor of Lucifer?) Is that of a luckless fallen angle, refusing to join him in his light. Lucifer himself was a fallen angle, and now Lucia clutches to
Fish Oil Health Benefits
Fish oil health benefits are exaggerated, says a new study appearing in the Canadian Medical Association Journal. And yet, it warns, increased consumer demand for fish oil is pushing fish populations to the brink. Medical scientists from St. Michael's Hospital and the University of Toronto have teamed with researchers from the University of British Columbia's Fisheries Centre and author Farley Mowat to closely examine the effects of health claims with regard to seafood. For years, international agencies concerned with health and nutrition have promoted seafood consumption. â€Å"Our concern is that fish stocks are under extreme pressure globally and that studies are still urgently required to define precisely who will benefit from fish oil,†says Dr. David J. A. Jenkins, a doctor at St. Michael's Hospital and a professor at the University of Toronto Faculty of Medicine's Department of Nutritional Sciences. Further, if we decide that fish oil supplementation is necessary for good health, then unicellular sources of ‘fish oil' like algae, yeasts, etc, should now be used, as they are in infant formula,†adds Dr. Jenkins. While some studies have reported fish oil health benefits healthy benefits, others have failed to show a significant effect. But these negative studies are often ignored and the result has been increased demand for seafood by consumers in the developed world, often at the expense of food security in developing nations. Governments and industry tell consumers to eat more fish because it is healthy,†explains Rashid Sumaila, director of the Fisheries Economics Research Unit at UBC Fisheries Centre and study co-author. â€Å"But where do we get these fish? They are increasingly coming from the waters around Africa and other places where food security is a problem. †At best, fish oils are just one factor out of many that may reduce ailments such as heart disease and researchers found that people who do not eat fish, such as vegetarians, are not at increased risk of illness. Furthermore, dietary recommendations to consume more fish are incompatible with the sustainability of ocean ecosystems, according to a concurrent study recently published in the International Journal of Epidemiology. â€Å"For people in Canada or the US, or in the EU, eating fish is one of many possible options, both in terms of a tasty meal, and in terms of a balanced diet,†says UBC fisheries researcher Daniel Pauly. â€Å"For many people in developing countries, fish is often their only source of protein. It would be irresponsible for us to ‘triage' food sources without verifying that fish oil indeed promotes human health. †Farley Mowat, co-author on this study, adds: â€Å"In the immediate future, human beings are going to have to find better ways to live. Our rape and pillage of the environment has to end before it becomes our end. The damage we have already done to life in the oceans is a prime example of our idiocy, and a last warning that we had better change our ways. â€Å"
