Petro-geology, petro-politics,and frontiers for Iraq(2005onward) Term Paper

Petro-geology, petro-politics,and frontiers for Iraq(2005onward) - Term Paper Example All these elements were already identifiable by the initial exploration geologists; thus a general procedure of exploration was to conduct drilling of the peak of the anticlines. Kirkuk is renown, very lengthy anticline, which was amongst the first sites to be drilled (Benko, 2008). The extensive reserves revealed in the carbonate basins gave a constructive response to the above mentioned discovery tactic, and in the preceding years a huge number of topographically articulate anticlines were bored. Even though a majority of these structures had a very huge amount of hydrocarbons, impenetrable exemptions do exist, or different explanations concerning reservoir rocks and their efficacy (Hips, 2008). In some oil mine fields of varying eminence, or gas and condensate was revealed in the matching reservoirs. It came to be noticed later on that cretaceous fonts are slightly established. The oil kept in the Cretaceous is obtained from a Cretaceous font. It is decayed in the open parts and n on-biodegraded in the deeper parts; though still at depth the tar is unaffected. In agreement with other regional research, the Jurassic foundation rocks are affluent and are in the oil window (Jassim & Goff, 2006). The carbonate font may give an explanation for the high quantity of sulphur and the considerably high viscosity, but the resultant oils must be of better quality than what is actually established. It was initially presumed that a sediment or gravitational division took place (Sarbazheri, Ghafor & Muhammed, 2009). All in all, more unstable divisions tend to be missing from these oil deposits. The system of Triassic must be late oil to damp gas established, and the petroleum established there keep up a correspondence to the proposed maturity of the origin (Pitman, Steinshouer & Lewan, 2005). Oil Frontiers in Iraq Iraqi Kurdistan region, celebrated by intercontinental petroleum firms as the final frontier for ashore gas and oil discovery, is making efforts to improve its en ergy infrastructure. Greeters at Erbil’s international airport have a sign that sums it all: Weatherford, General Electric, and Reliance-the forerunner of a wave of important new entrance prepared to bore wells or construct pipelines, energy factories and oil refineries (Navabpour, Angelier & Barrier, 2007). The main point of reference of the location’s gas and oil producers is that aid is within reach. This was the main motivation given the fact that in recent times the Kurdistan’s revolutionary oil and gas manufacturers had to be their own drilling and hauling service providers, engineers, repair men, and even mine cleaners. One of the founders of oil and gas exploration is the UAE that found Crescent Petroleum, which started manufacturing gas in Kurdistan in the late 2008. The Corporation’s CEO recounts the major challenges experienced in transporting over 60,000 metric tons of steel and marshalling numerous truckloads over the Turkish border in effort to establish their plant for oil and gas production. This was during the construction of the pipeline. They had to cross the rivers, construct bridges and clear the mines according to the report released by (Robert, 2006). The current situation is very different as power generation plant has been installed, facilitating a transition from the 185 MW supply of power to the current supply of 2,200 MW by use of a twin 50-year old hydroelectric power plant

Cross-Cultural Communication in the Management Research Paper

Cross-Cultural Communication in the Management - Research Paper Example In a progressively international construction market, communication problems will pose as one of the most crucial tests facing construction project managers. Having said that, the researcher recognized that an understanding of the importance and impacts of cross-cultural communication and the means by which it can be managed will provide the capacity to meet and get past these challenges; therefore justifying the need to study it. It consists of the effective rules for doing business, the boundaries between competitive and unethical behavior and the codes of conduct in business dealings. Business cultures differ and are affected by different cultural priorities and what is acceptable and allowable by society. This kind or culture is not immune to collision and that they particularly do so in the context of a foreign environment where business and cultural priorities differ from one’s own way of doing things. In addition, an integrated cultural framework is going to be devised so as to pinpoint the major differences in culture. To summarize, international project management necessitates an effective process regarding communication assessment. Tone identified several areas wherein varied cultures play a part in project management. He noted two situations that if not taken seriously and not dealt with will cause cultural difficulties. The first scenario is where a Canadian project manager for example and a manager in China, manage a construction bridge in a particular country which is both not their own.

1.Identify 10-15 food crops that originated in the Old World (Africa, Asia and Europe) and the New World (the Americas) - Essay Example Each of these groups of food crops originating from the separate worlds has an impact on the modern global food system. Rice is considered one of the most significant and main sources of food for more than three billion individuals in the world today. In the modern world, rice cultivation has contributed to poverty eradication in many parts of the world, enhanced food security, and also contributed to a lot of developments. In other worlds, rice cultivation has enable people from all corners of the world to access enough food to sustain their lives (419). As fruits, pineapples have a lot of health benefits. Including them in the diet means that an individual is benefiting from a balanced diet and hence certain illnesses associated with poor diets are eliminated. Pineapples are either sold fresh or are used to make fresh fruit juice. Fresh juice has a lot of health benefits. Cultivation of pineapples is also a source of revenue or capital to a lot of people in the world. People are also able to purchase pineapples and its products locally instead of importing. In doing so, revenue is maintained locally and hence farmers are able to expand and sustain their farming

Fast, global,and entrepreneurial; supply chain management , hong kong style and interview with victor fung - Case Study Example Several changes have been done since its establishment in a bid to conform to the recent demands in the supply chain management field. Globalization has brought about increased interactions among countries in different continents. As such there has been increased focus on eliminating some of the most recurrent challenges faced during conduction of international business such as language barrier. Organizations conducting international businesses have invested deeply in overcoming language barriers among other challenges leading to elimination of intermediaries such as interpreters. During the first years of its establishment, Li Fung ripped heavily from interpretation due to the ability of its founder to speak English. However, such a role in the modern day is seemingly irrelevant hence the need to come up with other strategies to gain competitive advantage. For instance, Li Fung came shifted focus to production of full products from the entire region rather than a single product from one place. This increased relevance of the company in the supply chain since an organization could rely on Li Fung to get all necessa ry materials required at one point. This implies that organizations need to constantly come up with strategies corresponding to market changes in order to prevent elimination. However, production techniques changed once again hence Li Fung was now charged with the responsibility of managing the entire production process for its clients to come with a finished product. However, changes in economic status in Hong Kong triggered yet another shift to employment of dispersed production. This shows that market status is heavily dependent on the economy among other external factors. The changes evident in the life span of Li Fung are a clear indicator of the many changes requiring attention taking effect in the supply chain management sector. This implies that

Lord of the Flies Essay Example for Free

Lord of the Flies Essay Every child, regardless of when, loses their innocence; it is inevitable. In Lord of the Flies, the reader can recognize this law live up to its word, namely in the protagonist Ralph. Upon arriving on the island, Ralph was oblivious to the circumstances he was soon to be subjected to. Ralph’s innocent and childlike mindset has distorted itself into that of a hostile hunter. In William Golding’s Lord of the Flies, the reader witnesses the Loss of Innocence theme and observes Ralph’s descent into impurity. Ralph is first portrayed as just another kid, waiting for his problems to disappear. He had no plan on how to get off the island, and no reason to worry about it; â€Å"daddy† would take care of it for him. Ralph was not concerned about what to do about the situation he was in, and told Piggy why. Ralph tells Piggy, â€Å" Daddy taught me. He’s a commander in the Navy. When he gets leave he’ll come and rescue us†¦ They’d tell him at the airport. † (7) Ralph relied upon the airport telling his father where their plane crashed, with little to no knowledge as to where they could have landed. Though the odds were very slim, Ralph counted on his daddy coming to get him from the island in the middle of the Pacific. He was like a helpless little child, grasping his daddy’s hand and waiting to be led. With the increase of time spent on the island, Ralph’s innocence begins to diminish. Ralph is no longer the helpless little child he once was when he first landed; Ralph has evolved from a benign child to a hostile hunter. After going hunting with the boys, Ralph tried to regain the group’s attention as they all focused on Jack’s’ wounded left arm. Ralph reminisced on how he hit the pig with his spear and then began to act as though Roger were the pig, jabbing at him while Roger rushed away. Soon, the group surrounded Robert, all participating in the jabbing: â€Å"Ralph too was fighting to get near, to get a handful of that brown, vulnerable flesh. The desire to squeeze and hurt was overmastering. † (101) The boys all got hold of Roger and, without any second thought, began to poke at him, hurting him as a result. The â€Å"innocent Ralph† would have attempted to prevent the actions, rather than beginning the prodding of Roger. Ralph has evidently lost his innocence and this situation shows no different. As Ralph spends more time on the island, he, along with the reader, becomes aware of his loss of innocence.. After the deaths of both Simon and Piggy, Ralph has officially become a loner. Everyone else on the island has transferred over to Jack’s group of uncivilized hunters, the polar opposite of the group once run under Ralph’s chieftainship. Knowing that Ralph is now an independent individual in hiding, Jack sweeps the island to ensure that he finds Ralph. After Samneric reveal Ralph’s position, however, Jack lights the island on fire so Ralph cannot escape the fiery wrath of the opposing chief. After desperately sprinting away from the hunters, Ralph runs into a naval officer. The officer questions Ralph about the group and after answering these questions, Ralph has another moment of clarity and begins sobbing. â€Å" Ralph wept for the end of innocence, the darkness of man’s heart, and the fall through the air of the true, wise friend called Piggy. † (182) After being given the chance to relax, Ralph begins to grasp the concept that he has changed throughout this entire experience. The innocent stage has now passed, for himself and the rest of the group. Ralph now knows that he is no different from the other children; all children lose their innocence at some point. Golding’s depiction of Ralph from the beginning of the novel to the end of the novel greatly reflects the theme of loss of innocence. Ralph evolves from the helpless child to the hostile hunter after the crises he is put through. Ralph is a representation of every child on the earth and the inescapable loss of innocence. Through Ralph, the reader can learn that a crisis, no matter the scale, can affect the victim.

The Count of Monte Cristo Essay Example for Free

The Count of Monte Cristo Essay I. The Count of Monte Cristo II. Characters Edmond Dantà ¨s The protagonist of the novel. Dantà ¨s is an intelligent, honest, and loving man who turns bitter and vengeful after he is framed for a crime he does not commit. When Dantà ¨s finds himself free and enormously wealthy, he takes it upon himself to act as the agent of Providence, rewarding those who have helped him in his plight and punishing those responsible for his years of agony. The Count of Monte Cristo The identity Dantà ¨s assumes when he emerges from prison and inherits his vast fortune. As a result, the Count of Monte Cristo is usually associated with a coldness and bitterness that comes from an existence based solely on vengeance. Lord Wilmore The identity of an eccentric English nobleman that Dantà ¨s assumes when committing acts of random generosity. Lord Wilmore contrasts sharply with Monte Cristo, who is associated with Dantà ¨s’s acts of bitterness and cruelty. Appropriately, Monte Cristo cites Lord Wilmore as one of his enemies. Abbà © Busoni Another of Dantà ¨s’s false personas. The disguise of Abbà © Busoni, an Italian priest, helps Dantà ¨s gain the trust of the people whom the count wants to manipulate because the name connotes religious authority. Sinbad the Sailor The name Dantà ¨s uses as the signature for his anonymous gift to Morrel. Sinbad the Sailor is also the persona Dantà ¨s adopts during his time in Italy. Mercà ©dà ¨s Dantà ¨s’s beautiful and good fiancà ©e. Though Mercà ©dà ¨s marries another man, Fernand Mondego, while Dantà ¨s is in prison, she never stops loving Dantà ¨s. Mercà ©dà ¨s is one of the few whom Dantà ¨s both punishes (for her disloyalty) and rewards (for her enduring love and underlying goodness). Abbà © Faria A priest and brilliant thinker whom Dantà ¨s meets in prison. Abbà © Faria becomes Dantà ¨s’s intellectual father: during their many years as prisoners, he teaches Dantà ¨s history, science, art, and many languages. He then bequeaths to Dantà ¨s his vast hidden fortune. Abbà © Faria is the most important catalyst in Dantà ¨s’s transformation into the vengeful Count of Monte Cristo. Fernand Mondego Dantà ¨s’s rival for Mercà ©dà ¨s’s affections. Mondego helps in framing Dantà ¨s for treason and then marries Mercà ©dà ¨s himself when Dantà ¨s is imprisoned. Through acts of treachery Mondego becomes a wealthy and powerful man and takes on the name of the Count de Morcerf. He is the first victim of Dantà ¨s’s vengeance. Albert de Morcerf The son of Fernand Mondego and Mercà ©dà ¨s. Unlike his father, Albert is brave, honest, and kind. Mercà ©dà ¨s’s devotion to both Albert and Dantà ¨s allows Monte Cristo to realize her unchanging love for him and causes him to think more deeply about his sole desire for revenge. Signor Bertuccio Dantà ¨s’s steward. Though Bertuccio is loyal and adept, Dantà ¨s chooses him as his steward not for his personal qualities but because of his vendetta against Villefort. III. Settings The movie takes place in a number of settings, but most of the plot occurs in Marseilles Chateau dIf, and Paris (France), Rome, the island of Monte Cristo, and Greece. IV. Summary Edmond is sailing in French waters along with his best friend, Fernand, when their captain falls ill. They stop for help at a nearby island, which happens to be where Napolean Bonaparte is in hiding. Bonaparte pulls aside Edmond and asks him to deliver an innocent letter to an old friend in Marseille, France. Edmond agrees, as that is the price for the use of Napoleans physician. The captain unfortunately dies, so the crew returns home to Marseille. Edmond is made captain for his bravery in seeking a physician, and the first mate comes to despise him for it. Fernand finds out about the letter, and reads it while Edmond is sleeping, and is angry that Edmond did not tell him about it. Edmond, not knowing that Fernand knows about the letter, rushes to greet his fiance, Mercedes, and tell her that they can now be married as he was just promoted to captain. This is also the point in the movie when you realize that Fernand is in love wiht Mercedes, but she loves Edmond. Fernand, still angry, decides to work together with the furious first mate, and get Edmond arrested for treason, which he didnt commit. Fernand works also with a very important magistrate, Villefort, whos father is the man Edmond was to deliver the letter to. (Villefort does not know of this). Thus, Edmond is arrested, and thrown into a remote island prison by the name of Chateau Dif. There, he meets Priest, who teaches him many valuable lessons about life, how to sword fight, and give Edmond a proper education. All this is in turn for Edmond helping to dig, in order to escape the prison. For 13 years, Edmond is held captive in the Chateau Dif, and unknown to Edmond, a letter was sent to his family and Mercedes saying that he was executed on grounds of treason. Finally, Edmond escapes when the priest dies, and becomes part of a crew on a merchant vessel, along with his good riend Jaccapo. After 3 months, Edmond is released along with Jaccapo, and they go in search of finding out what has happened to Edmonds loved ones. They find out that Edmonds father commited suicide, and the Mercedes wed Fernand a month after learning of Edmonds execution. Edmond has by this time (with the help of the priest while in prison) figured out that he was framed by Fernand and the others. Thus, he and Jaccapo sail to a remote island that the Priest told Edmond about, and there they find a treasure, making Edmond extremely wealthy. Edmond decides to become a count in order to get revenge on those who betrayed him, so he becomes The COunt of Monte Cristo, being the treasure he found The Treasure of Monte Cristo. Soon after, he saves Fernand and Mercedes son Alber from captivity, and thus enters the lives of those he is trying to hurt like they hurt him. Mercedes begins to suspect that The Count is really Edmond, and when she confronts him privately, he denies it but slips and she realizes that he really is Edmond. Then, they kiss, and realize that they are still in love, so Mercedes goes back ot her Chateau to inform Fernand that she is leaving him, when Fernand tells her that he has gone bankrupt (which is really Edmonds doing, but he doesnt know this) and is leaving the country. (By this time, Villefort has been convicted of murdering his father and sent to jail, also doings of Edmonds). Mercedes preceds to inform Fernand that Alber is not his son, but Edmonds. Fernand becomes angry and goes out to his old, abandoned villa to collect the gold he had supposedly stolen from The Count of Monte Cristo, only to find that it is not there (Edmonds doings, again). Then, Edmond shows up, and tells Fernand where he has been all these years, and they begin a duel, only to be stopped by Mercedes and Alber. Mercedes then tells Edmond that Alber is really his son, not Fernands. Fernand then shoots Mercedes in the shoulder (she lives) and runs off. Edmond follows him and they begin sword fighting again. Fibally, Edmond kills Fernand, and goes back to Mercedes and Alber and Jaccapo. At the very end, Edmond buys the Chateau Dif thanks the Priest for his wisdom and help. V. Value Implication The â€Å"Count of Monte Cristo† is the greatest tale of betrayal, adventure, and revenge the world has ever known. One of the morals in that story is what goes around comes around. The people who betrayed the count ended up by paying with their lives as he cleverly took his revenge on each one. Plus, the fact that the count actually really did find treasure and good friends (in the form of pirates) meant that he was a good person who attracted good people. Regardless of the fact that the pirates could have treated him badly and even shot him when he found the treasure, they didnt, they became his friends and they benefitted from his success. The main moral is that the bad deeds we do in life do not go unpunished and the good ones get rewarded.

Metal Casting Process

Metal Casting Process Materials and Design Pressure Die Casting Process Executive Summary Since the discovery of the earths minerals, metal casting process has played an important role in society. An integral part of every technological advance, castings have allowed us to build equipment to feed our people, fight for democracy, build infrastructure and manufacture cars, trains and airplanes. In general, castings have been and will continue to be the key ingredient in the recipe for a better way of life. There are various types of casting process, such as sand-casting, permanent-mould casting, investment casting and die-casting. Due to the words limitation, in this investigative study, only the development, technical challenges, recent findings, future direction, range of applications and shortcomings of pressure die-casting process will be discussed. Introduction Pressure Die-casting is similar to permanent mold casting except that the metal is injected into the mold under high pressure of 7-350Mpa (1,000-50,000) psi. This high pressure will not be removed till the solidification is finished. It is called die-casting, because the molds in this casting operation are called dies. Metal is forced into the die cavity by the pressure is the most notable feature that shows this process is different from others in the casting category (Long et al., 2008). In this technique, the mould will not be destroyed after each cast but is permanent, being made of a metal such as cast iron or steel. There are two types of pressure die casting processes, High pressure die casting and low pressure casting. High pressure die casting is the most widely used, representing about 50% of all light alloys casting production. Low pressure die casting currently accounts for about 20% of production and its use is increasing. Rests are gravity die casting, vacuum die casting and squeeze casting process (AZOM, 2008). Literature Review High pressure die casting process In high pressure die casting process, the liquid metal is injected at high speed and high pressure into a metal mould. A schematic view of high pressure die casting is given in Figure 1. Above equipment contains two vertical platens on which bolsters are located which hold the die halves. One of the platen is fixed and the other can move to open and close the die. A measured amount of metal is poured into the shot sleeve and then introduced into the mould cavity using a hydraulically-driven piston. Once the metal has solidified, the die is opened and the casting removed (AZOM, 2008). For high pressure die casting process, special precaution must be considered to avoid too much gas inclusions which cause blistering during the subsequent heat treatment or wielding of the casting product. Since the casting machine and its dies are quite costly, only high-volume production will use the pressure die casting process for economical reason (AZOM, 2008). Low pressure die casting In Figure 2, the die is filled from a pressurised crucible below. Low-pressure die casting is especially suited to the production of components that are symmetric about an axis of rotation. Light automotive wheels are normally manufactured by this technique (AZOM, 2008). Benefits of the process development Over the last three years the biggest improvement of die casting process is the development of material property data and interfacial hear transfer coefficients. Material property thermal data is the essential part of any simulation program, which has been developed for various mold materials, feeding system and metal alloys, such as aluminum, steel and compacted graphite iron. Furthermore, the work done to understand the fluid mechanics of filters is another development of the die casting process, which include the developed pressure drop data for pressed, extruded and reticulated foam filters and these data is easily available in the industry literature (ALLBUSINESS, 2008). There are types of the casting defects occur during production of pressure die casting process such as insufficient pouring, cooling separated, crack and shrink. They are formed in the mold filling and solidification processes, which contributed to the final casting performance. The processes of mold filling and solidification are developed in time sequence while the casting defects are forming, which can be reflected by its numerical simulation in order to predict the locations of the casting defects (Minaie and Voller, 1998). Numerical simulations of mold filling and solidification processes include numerical analysis, heat transfer, fluid mechanics, solidification theory, engineering mechanics, computer aid graph analysis etc. The mold filling process can be described very precisely and the reliable initial temperature field is provided for the next solidification process by using the advantage of numerical simulation on temperature and fluid fields, which benefits to elevate the simulation accuracy of solidification process. Numerical simulations of mold filling and solidification processes, which play the key function in the casting production, are the world known leading area, widening and promoting the development of casting subject by using the advance computer technology. And it also initiates a new way to improve the casting quality (Baicheng and Houfa, 1998). Technical Challenges Details The molten metal flow is the major issue that relates to the mold filling process, heat and mass transfer flow process at changeable temperature accompanied with heat loss and solidification. This process can be presented by the continuity and momentum equations. In addition, the energy balance equation can describe the heat exchange between the molten metal and the casting chamber. The consideration of position and movement of the free surface is the key for the calculation of unstable flow. Also, it is essential to deal with the boundary conditions of the free surface. There for, the mathematical equations can be expressed as follows [1], [2], [3], [4] and where à Ã‚  is the density and u is the velocity The numerical simulation is a non-linear instantaneous thermal analysis in the solidification process. The casting form changes gradually with the decreasing of temperature from liquid state to semi-solid and solid states, in which many physical process and phenomenon played an important role for the casting quality take place, and the temperature field of the casting varies with the time. Therefore, the shrinkage cavity and slack can be predicted with the numerical simulations of the filling and solidification processes (Laurent and Rigaunt, 1992). Range of Applications CAD/CAM/CAE is now as an essential part to keep pace with growing technology and demand for quality, low cost, precision and faster delivery in tool engineering. The followings are the few latest methods, which are being used today in die making industry: Scanning of product to be die cast. CAD/CAM (Computer added design and manufacturing) CAPP (computer added process planning) CAI (computer added inspection) 2D drawing to 3D modeling 3D model to 2D drawing Black-box designing (conceptual base designing) Analysis Simulation (stress, Strain, thermal analysis etc.) Analysis for Gate, runner, ejector pins and cooling line etc. NC data generation Rapid prototyping Concurrent engineering Pressure die casting process is widely used in resource producing company, such as world class Aluminum company Alcoa and NALCO, and copper alloy giant Kennecott. Drawbacks The formation of blow-holes in the die casting is a major drawback, which is resulting from the turbulence produced by the high velocity when the liquid metal alloy is injected. Another major drawback is inevitable shrinkage of the casting as it solidifies, and which is proportional to the temperature at which the alloy is injected. Though cheap to make, the poor quality of current die cast components therefore makes the use of finer quality alloys unfeasible (Moschini and Renzo, 1998). Recent finding Future direction In the world of computer simulation time, the pressure die casting process improvements move very fast in the foundry industry today, a lot has changed in the last few years, for example, three years ago the computers that industry companies using to process the die casting process simulation were based on Unix workstations, which was more than $30,000 and the only way to analyze the filling of a mold cavity was using NavierStokes equations, which was extremely slow. Nowadays, the personal computer (PC) conversion is finished, some of new machines can run 20-30 times faster than the one in three years ago. For example, a very complicated filling and solidification work that used to run days and days can be completed in one hour (ALLBUSINESS, 2008). The concurrent development of optimization techniques have been capitalized on and incorporated by the software companies into their programs. At first glance, this allows the user to let the computer help optimize such things as riser placement and size and chill locations. However it isnt hard to imagine that this is just the beginning, and that we are about to get on a journey in which die casting process simulation programs soon will perform what is unthinkable today (ALLBUSINESS, 2008). Conclusion Die casting molds tend to be expensive as they are made from hardened steel-also the cycle time for building these tend to be long. Also the stronger and harder metals such as iron and steel cannot be die-cast in the past. However, by the developing of the numerical simulations system and optimization techniques, these issues are no longer impede the pace of progress in the modern world. Numerical simulations and optimization techniques can help foster the success and viability of the foundry industry for many years to come. The more capability and accuracy that is built into our simulation tools, the better and more efficient casting can be produced.
