In Dept To China Essays - Steelmaking, Agricultural Machinery

In Dept To China The World is forever in debt to China for its innovations. Ancient China was extreme advance and many of its discoveries are still in use today. This is what Robert Temple, the author of The Genius of China 3000 years of science, discovery and invention. The book is based on 11 main parts of Chinese innovation. Within these 11 categories, there are 3 main parts that contain the most significant inventions. Robert Temple concentrates the bulk of his examples in these three categories, agriculture, domestic and industrial technology , and engineering. Temple's examples were not limited to these fields of innovation. The Chinese excelled in many other areas, including mathematics, warfare and transportation, to name a few. Although Temple wrote about eleven fields of invention, I feel that these three sections contain the greatest examples of Chinese innovation, and the debt that the modern world owes China. The first main area is the field of engineering. Within this chapter, the devel opment of iron and steel is the greatest achievement. The development of iron and steel led to other advances. By at least the 4th century the Chinese have developed blast furnaces to obtain cast iron from iron ore. This was 1200 years before the first blast furnace showed up in Europe. The reasons that the author gave to explain the reasons why the Chinese developed this technology are simple. The Chinese had access to large amounts of clay, the key ingredient in making blast furnaces. The Chinese also figured out that by adding a substance they called :Black Earth,? they could lower the melting point of iron. Another major invention of the Chinese, that led to other achievements, is steel. The common belief today is that Henry Bessemer discovered the process of refining iron into steel. The fact is Chinese had developed the process to refine iron into steel in the second century BC The Chinese learned that by injecting oxygen into the blast furnace, they could remove the carbon fr om the iron. The Chinese called this process the ?hundred refinings method? since they repeated the process that many times. The finished product was highly prized in China for its strength and ability to hold an edge on a sword. The Chinese would weld the steel onto weaker iron thus creating a strong edge and a superior weapon. The Chinese iron and steel workers were the best at making different types of metals into modern times. But then, no one else could have done so at the time, since iron existed nowhere else but in China. The Chinese invented the chain pump in the first century AD The chain pump allows water to the pumped from lower to higher elevations. The chain pumps were used for draining and pumping in civil engineering, but what is more important is it was used for irrigation. Irrigation allows for greater and more intense farming, thus resulting in a better crop yield. With the greater crop yields larger populations can be supported. The chain pump was exported to all parts of the world by way of visiting ambassadors and dignitaries. The first European chain pump appeared in the sixteenth century, and was a direct copy of the Chinese version. The second area of great Chinese achievement is in domestic and industrial technology. The most recognized Chinese invention is in the field of domestic and industrial technology, paper. Paper was invented around the second century BC and was used as clothing. One might not believe that paper could be used as clothing, but the paper made at that time used thicker and tougher paper fibers. Not only was paper used for clothing, it was also used for military body armor. The Chinese found out that pleated sheets of paper could stop the penetration of arrows. The paper armor was standard issue with Chinese land and sea units. Paper's writing property was not discovered till about one century after its discovery. The earliest example of writing on paper was found an abandon military post. The paper found dates bac k to 110 AD and contained two dozen readable characters. The area that let China grow and expand was the innovations in the area of agriculture.

Mineral Management Service in the federal Department of the Interior Research Paper

Mineral Management Service in the federal Department of the Interior - Research Paper Example In fact, accusations of drug use and sexual misbehavior linking employees of Mineral Management Services and their industry counterparts expose actions that go beyond what is revealed in the agencies. An eye-opening series of report compiled in 2008 by the inspector general of the Department of the Interior exposed a shocking level of corruption that exist in the Minerals Management service (MMS) coupled with a cozy relationship between its employees and the Industry officials, that involves a high scale of culture of substance abuse and promiscuity within the agency (Abramowitz and Mufson, 2007). MMS is charged with the responsibility of collecting royalties from different companies, for these companies and to give them the right to produce and trade in oil and gas within the federal boundary. For instance, in the year 2007 alone, MMS collected a total of $9 billion from oil and gas royalties, and hence, this made this sector to be one of the chief springs of revenue for the United States. This agency in addition to that, also manages the Royalty-in Kind programs through its Denver office, via which it purchases the oil and gas from these energy firms and then resell it to refinery firms. In this office, based on the report, the inspector deduced that the officials of the MMS Royalty-in Kind program habitually guzzled alcohol at industry functions and even takes cocaine and marijuana. Worse of all, they had sexual relationships with these oil and gas representatives. According to the report, the Inspector general purport that more than a third of Royalty-in Kind officials were involved in taking bribes and gifts in exchange of contracts. This kind of messy arrangement and relationship cost a tax payer over$4 million dollar Literature Review According to the report written by Daniel Carpenter and David Moss, 2011, the disbanding of the Minerals Management Service, depicts how poorly the regulatory industry was functioning. The literature shows how this body was marred by rotten regulatory relationship, accusations in drug use and sexual misbehavior. Consequently, there was a proposal of disbanding of the agency by disintegrating and splitting its planning, revenue collection and regulatory role into three independent bodies of organizations. However, a keen evaluation of this step owing to the external political and social influence that at one time rocked the MMS operations, the reorganizations and reinvention will not automatically advance and develop how the federal or the government is managing the minerals within the federal boundary. Similarly, the memorandum report compiled in May 2010 briefing the outcome of the investigation that was done, probing the Lake Charles district office, one of the five major offices charged with the responsibility of overseeing gas and oil operations along the Gulf of Mexico. This report also revealed the level at which some of the MMS employees in the office collected gifts from offshore operators, ra nging from lunches, admission to sport events to participation in events with some of the senior industry personnel. Besides accepting gifts, some MMS employees in senior posts particularly the inspectors permitted the some energy companies to fill out inspection forms by themselves and lastly, the report records a series of e-mail letters exchanged between the former inspector and a certain employee purportedly an offshore operator assuring him his job security at that company. This is because during this era, the inspector was mandated to

Nursing Case Study - Essay Example Prolonged immobilization is one of the main causes for DVT (Poelkens, et.al., p. 111). In this case, the patient’s decompression surgery could have contributed to the formation of the thrombus, and such thrombus later travelled up his chest cavity, manifesting as pulmonary embolism. Initially, a thrombus which separates from its original site then travels through the circulatory system then on to the inferior venacava (Smulders, p. 23). The right ventricle then pushes the thrombus to the pulmonary arteries where the thrombus eventually lodges. Since the pulmonary arteries branch out to smaller blood vessels, the thrombus will likely lodge itself there (Smulders, p. 23). Multiple thrombi may be seen in the pulmonary area and they may be big or microscopic in size; the bigger ones may totally or partially block the major branches of the pulmonary artery. Such thrombus cuts the blood flow in the pulmonary arteries and this can cause increased resistance to blood flow in the pulmonary blood vessels. In instances of 50-60% decreased perfusion, pulmonary hypertension, right ventricle strain, and cardiac heart failure may occur (McGill University). Pulmonary reflexes also cause the release of humoral substances which then lead to the constriction of pulmonary blood ve ssels, thereby increasing vascular resistance. The pulmonary embolism, along with the patient’s lumbar decompression is causing the manifestation of his other symptoms including: tachypnoea, pleuritic chest pain, tachycardia, dyspnoea, and fever. Assessment The patient’s pulmonary embolism was diagnosed; however it is still important to note the clinical presentation of this condition in the patient. Since the patient is at a high risk for having PE, it is crucial to note the manifestations of this incident. Some common symptoms include: dyspnoea, pleuritic chest pain, tachypnoea, and tachycardia (Fedullo and Tapson, p. 1247). However, these symptoms cannot sufficiently establish a finding of PE. These symptoms are all apparent in this patient. These may all indeed point to his pulmonary embolism, however, some of these symptoms may be due to his lumbar decompression surgery. Other diagnostic tests may be used in order to detect pulmonary embolism. The first test is the D-dimer test which evaluates

Orbids of the Skull

Orbids of the Skull Sarah Ferreira 1.INTRODUCTION The orbits of a human skull is the space in which the eye and it’s appendages are located. The two orbits in the human skull are conical â€Å"holes† that opens into the midline of the face and point back into the head. Each orbit includes an apex, four walls and a base. The functions of these orbits is firstly to keep the eye â€Å"safe† from any mechanical injury and secondly to supply an entrance for the optic nerve(that transports visual information from the eye’s retina to the vision centers in the brain through electrical impulses) to the brain. A thorough understanding of the anatomy of the orbits of the human skull is very important to any doctor in order to comprehend any disorders that patients might experience that are related to the eye socket itself, as well as to understand the surgical management of this region in the human skull. 2.The orbit of the skull 2.1The general location of the orbits in the human skull: The orbit in the human skull lies anterior to the temporal fossa (laterally) and anterior to the middle cranial fossa (medially). It’s also situated superior to the maxillary air sinus, lateral to the nasal space as well as below the anterior cranial fossa. 2.2The shape of the orbit of the skull: The shape of the orbit in the human skull looks like a pyramid that has four distinctive sides (â€Å"walls†), but as one moves posterior, it becomes three sided( toward the apex). The most posterior portion of the pyramid shaped orbit is the apex (of the orbit) and it’s positioned at the craniofacial junction. ( The apex is also where the optic canal (that contains the central retina vein, ophthalmic artery, symphathetic nerve and optic nerve) opens into the posterior part of the orbit and it forms the tip of this pyramid shaped â€Å"cavity† or structure.) 2.3The bones of the orbit of the skull and their bone classification: There are seven bones that make up the orbit namely the: 1)The Maxillary bone(that is also classified an irregular bone) 2)The orbital plate of the Frontal bone(that is also classified as an irregular bone) 3)The Zygomatic bone(that is also classified as a flat bone) 4)The Ethmoidal bone(that is also classified as an irregular bone) 5)The Lacrimal bone(that is also classified as a flat bone) 6) The Palative bone (that is also classified as an irregular bone) 7) The Sphenoid bone (that is also classified as an irregular bone) All of the above mentioned bones also form part of the human skull. The orbit also contains fissures and fossae where various blood vessels and nerves pass through. 2.4The walls of the orbit The orbit as mentioned earlier consist of four sides or â€Å"walls†. The facial and cranial bones that forms the structure of the orbits also forms these four walls. The walls of the orbit of the skull are as follows: 1)The superior wall/ â€Å"roof† 2)The lateral wall 3)The inferior wall/ â€Å"floor† 4)The medial wall. 3Introduction to the bones of the orbit and the orbital walls that they form: The superior margin and most of the roof of the orbit are formed by the frontal bones of the orbital plate. The inferomedial margin and the floor of the orbit is also formed by the maxilla bone. The anterior part of the lateral wall and the inferolateral margin of the orbit is also formed by the zygomatic bone. Much of the medial wall of the orbit is also formed by the lateral mass of the ethmoid bone. There are also a number of ways in which the sphenoid bone contributes to the structure of the orbit: Firstly, the lateral wall posterior to the Zygomatic bone is constituted by the greater wing of the sphenoid bone and secondly the posterior margin of the roof (or superior wall) is formed by the lesser wing of the sphenoid bone.Thirdly the optic canal (that provide a passage for the optic canal and the optic nerve into the orbital space) which is in the apex of the orbit, is also framed by the roots of the lesser wing of the sphenoid bone.( This†roots† of the lesser wing a lso connects it to the body of the sphenoid bone.) The medial wall of the orbit( that is between the frontal process of the maxilla and the lateral mass of the ethmoid is completed by the small, curved , lacrimal bone. The posterior angle of the floor or inferior wall is completed by the orbital process of the palatine bone that is insinuated behind the maxilla and underneath the ethmoid bone. 3.1The superior wall or â€Å"roof† The lesser wing of the sphenoid bone constitutes/forms the posterior margin of the superior wall and also surrounds the optic canal( that â€Å"ac† as a channel for the optic nerve and ophthalmic artery). Thus the optic canal is situated posteriorly in the wing of the sphenoid bone that is smaller i.e. the lesser wing and this canal also communicates with the middle cranial fossa. (A fossa is a hollow or a shallow depression.) The superior margin of the bony cavity that contains the human eyeball are formed by the orbital plate of the frontal bone and this bone forms almost everything of the superior wall of the orbit except the posterior extremity of the superior wall. This specific part (the posterior extremity) is formed by the lesser wing of the sphenoid bone. The superior orbital fissure is also situated posteriorly between the greater wing of the sphenoid bone and the lesser wing of the sphenoid bone. (This fissure also communicates with the middle cranial fossa and also provides a passage for the frontal nerve, lacrimal nerve, oculomotor nerve, trochlear nerve, abducent nerve, nasociliary nerve and lastly the superior ophthalmic vein). A fossa for the lacrimal gland is made by the roof that rises laterally above the level of the rim of the orbit. The superior orbitals margin’s contour is laterally sharp and medially round. The supraorbital notch also leads from the orbit onto the face at the point of transition. On the frontal bones maxillary process, a small trochlear fossa that is in the anterior medial angle of the orbit gives an attachment to the trochlea. 3.2The Medial wall The medial wall consists of 4 bones namely: the sphenoid bone, ethmoid bone, lacrimal bone and maxillary bone. Thus the frontal process of the maxilla largely constitutes the medial margin of the orbit. The shorter maxillary process of the frontal bone are also met by the rising of the frontal process of the maxilla. The maxilla itself contributes little more than the rim to the medial orbital wall. The lacrimal bone, that has an irregular shape, articulates vertically with the frontal process of the maxilla within the orbit. The lacrimal sac’s fossa are framed or formed by both of these bones. The bony nasolacrimal canal is also continuous with the fossa which also proceed into the inferior nasal meatus below( that is the gap(space) covered by the inferior nasal concha. Posteriorly the fossa is bounded by a vertical ridge (that is named the lacrimal crest) and from this the orbital surface of the lacrimal bone increases posteriorly to meet the lateral mass of the ethmoid bone. The upper part of the nasal cavity are separated from the orbit by the lateral mass of the ethmoid bone. The lateral mass of the ethmoid is pneumatized extensively by the ethmoid air cells and in many skulls this gives the medial wall the appearance or likeness of an unviolated honeycomb. The thinnest part of the wall is the lamina papyracea which means a â€Å"layer as thin as paper† The frontoethmoidal suture is where the medial wall and the roof of the orbit mets. Across this boundary, the ethmoid air cells of the lateral mass extend upward into the overlying frontal bone.The anterior and posterior ethmoidal foramina open out of the orbit along the suture line into canals that pass horizontally between adjacent air cells. The first leads onto the upper surface of the cribriform plate, the second into the posterior ethmoidal and sphenoid air sinuses. 3.3The Lateral wall The Zygomatic bone forms the lateral margin and wall of the orbit and the greater wing of the sphenoid bone, completes this lateral wall The greater wing of the sphenoid also does not articulate with the lesser wing of the sphenoid or the maxilla bone and because of this there is two gaps posteriorly. The first â€Å"gap† is the superior orbital fissure that is located between the lateral wall and the superior wall and the second†gap† is the inferior orbital fissure that located between the floor( also called the inferior wall ) and the lateral wall. These 2 fissures converge in the apex of the orbit of the skull that is just lateral to he optic canal. The inferior orbital fissure is roughly in line with the zygomatico-orbital foramen that opens in the orbital surface of the zygomatic bone.h This Zygomatic orbital foramen can be doubled or multiple or it may be so hidden as to be virtually missed by the human eye. 3.4The floor or inferior wall The maxilla(medially) and the Zygomatic bone(laterally) forms the inferior margin of the orbit that is also named the floor. The floor is also the shortest of all the orbit’s walls) The whole of the orbit floor is also virtually formed by the maxilla bone and the Zygomatic bone. The maxilla bone constitutes almost all of the surface of the floor except the extreme lateral angle.The roof of the maxillary air sinus is also formed by the bone of the floor that is very thin. The floor is completed in front of the apex by the small orbital process of the palatine bone.The inferior orbital fissure is left by the prominent infraorbital groove and this prominent infraorbital groove runs directly forward on the surface of the maxilla.This groove (halfway across the floor of the orbit) becomes continuous with the infraorbital canal( thus the infraorbital groove (and canal) is located in the inferior wall of the orbit and in the maxilla’s orbital plate and it â€Å"transfer† the blood vessels and the infraorbital nerve) , which eventually ends in the infraorbital foramen ( on the anterior surface of the maxilla below the orbital margin. 4The neurovascular portals in the orbit’s walls and in the apex( some of them ( the nerves and arteries that go through passages in the orbit and apex) are discussed below.): 4.1The apex From the middle cranial fossa the optic canal opens directly into the apex of the orbit. The ophthalmic branch of the internal carotid artery as well as the optic nerve(that’s covered by all meningeal layers) goes through the optic canal. Between the orbit and the middle cranial fossa the main passageway is the superior orbital fissure. 4.2The Medial wall The anterior and posterior ethmoidal branches of the nasociliary nerve are transmitted by the anterior and posterior ethmoidel foramina. Corresponding branches of the ophthalmic artery and veins draining to the superior ophthalmic vein also accompanies them. 4.3The Roof The supraorbital nerve and vessels are transmitted by the supraorbital notch( or foramen) onto the forehead. The supraorbital nerve is the larger extension of the frontal nerve and the artery is from the ophthalmic artery. 4.4Floor The infraorbital and zygomatic nerves and vessels are â€Å"transferred† by the inferior orbital fissure. The infraorbital nerve and vessels are carried from the inferior orbital fissure to the infra orbital foramen(through this foramen they appear onto the face) , by the infraorbital canal and the infraorbital groove. 4.5Lateral wall The zygomatic orbital foramen transmits the zygomatic vessels and the zygomatic nerves into the zygomaric bone( this happens beyond the lateral end of the inferior orbital fissure) The Zygomatoc facial foramen is the passageway through which the zygomatico facial nerve and vessel appear on to the head. It may happen that there are two foramens rather than one and this is not unusual. The zygomaticotemporal foramen is also the passageway through which the zygomaticotemporal nerve and vessels emerge into the temporal fossa. Picture of the orbits 5Possible clinical application in Radiography In Radiography(orbital Radiogrpahy) injury to they eye or trauma to the eye are detected by orbital x rays. ( Orbital x-rays are x-ray images of the left and right eye sockets in the human skull. It also includes the frontal sinuses and maxillary sinuses). Orbital x-rays are also used to detect changes in the structure of the eye, which may lead to various diseases, as well as to detect foreign bodies in the eye that a opthalmoscope( that’s an instrument that detect foreign bodies in the eye) cannot â€Å"spot† In the Radiography department there is going to be patients who have fractures and diseases of the orbitals. Some of the fractures encountered could be a fracture of the zygomatic arch, displacement of the zygomatico-frontal suture, infraorbital fractures, etc. It will be expected of every qualified Radiographer to take orbital x-ray images of these patients orbitals. To be able to do this a Radiographer must be familiar with complex anatomy of the orbits in the skull and it associated soft tissue . For example if a patients that’s been in a car accident has fractured his orbitals and this resulted in a fracture of the zygomatic arch, then it would be expected of a radiographer to know where this zygomatic arch is located in order to take an orbital x-ray image of that area. A Radiographer must also have sufficient knowledge to be able take an orbital x ray image in the correct angle or to discern when to take several x-rays (from different angles) in order to show the fractur e to the zygomatic arch more clearly. It may happen in serious emergency cases that the Radiographer must firstly look for any damage on the patients face(before he/she can take an x-ray) , and if this radiographer doesn’t know where the facial bones or orbital bones is located then it wouldn’t help taking an image of the wrong facial bone, because that would be of no usage to the doctors seeing the orbital x-rays, because they want to see the fracture in order to make a diagnosis. A doctor may also ask a radiographer if she can see anything abnormal on the x-ray and then again this radiographer must be able to identify the bones and the location of the fractures. Thus it is very important for a radiographer to know where the orbitals lie and of what bones it consists. 6CONCLUSION From the above mentioned research I conclude that it is very necessary for a radiographer to know the orbits of the eye in order to take valuable x-ray orbital images of this area. The orbitals of the human skull is also of utmost importance , because of the fact that it contains the eye, ( a vital organ that is used in almost every activity of a human being ex. from reading the newspaper to crossing the street) and thus patients that has any damage to this area need to be helped swiftly before a minor orbital injury could proceed to a life threatening injury and results in the patient losing his eye. A Radiographer also pays an important role in â€Å"helping† these patients and must know the anatomy of the orbits in order to supply the doctors with the needed medical information that would help doctors to make a diagnosis.

Enironmental Pollution Essay

Environmental Pollution is one of the biggest challenges faced by most societies in this modern era. It has become a paradox of our time that urbanization and development be associated with environmental degradation. In man’s quest for social growth, nonchalance to nature’s laws have set in and this has disturbed a number of natural phenomena. The industrial revolution has brought with it technological advancement, such as the discovery of oil and fossil fuels and its virtually universal use in a diversity of industries. Further more rapid growth in population is established to be the fundamental cause of environmental framework collapse. Population growth increases the need to produce consumer commodities and this desire is transformed into a necessity to abuse environmental resources. Population growth creates certain negative environmental issues. These issues could be economic or social by nature. Their consequences range from a decline in air and water quality as well as deterioration in infrastructure and significant health hazards. A rapid growth in human population within the city propagates pressure on the framework of such cities and its natural resources. As cities begin to expand, they take a toll on existing rural areas, creating diverse environmental challenges such as reduced biological habitat as well as pollution of nature’s resources. The increased densities of industrial areas within cities, large number of automobiles and commercial enterprises add to increased health hazards and complete breakdown of ecosystem. Development of thought Our environment plays an important role in life. Man has equally been an active participant in the process of impacting on the environment through population and greenhouse effects. Obviously the growing population indicates a higher usage of resources thus leading to a greater deal of increased pollution. Therefore pollution of the environment has become an issue of significant discussions and diverse consequences. In recent times, the rapid growth has forced the natural environment to change drastically. A greater part of such change can be concluded to be negative with daring implications. Conclusion In light of the mentioned consequences of environmental pollution and the already visible degradation it has imposed on the environment. I would recommend the following bearing in mind that significant measures which must be cost effective and in line with budgetary allocations be taken into consideration. Pollution control Legislation of point sources The social, economic and ecological significance of conservation of the environment cannot be contestable; if pollution is to be maximally reduced, the need to appraise or look into the current levels of pollution, and environmental protection legislations within the city, with a view of presenting a new legislation. New legislated standards should be proposed since already existing legislations are found to be somewhat irregular and deficient. Also the advantages and possible problems of the proposed legislation can be debated upon and discussed. Encourage alternative transportation Alternative means of transport should be highly promoted. Cycling and walking do not propagate any sort of environmental degradation as opposed to the use of vehicles, which through the use of gas and fossil fuels are a significant actor in the downward slide of the negative environmental conditions. This recommendation takes into consideration that this measure might affect the convenience and time related factor that society has grown to enjoy from such vehicle technology. Establish green spaces or urban forestry The establishment of green spaces and urban forestry would lead to a significant decline in civilizations environmental footprints on the environment, meaning the least amount of pollution and emissions. This will facilitate the cleaning of emissions as they are released as well as restoring the ecosystem and natural balance of the environment. Of course this will have to be done without curtailing people’s freedom and rights or the world’s economy. Promote fuel-efficient cars It is a fact that a large percentage of pollution comes from emission of vehicles. It is recommended that alternative fuels or fuel efficient vehicles be encouraged. Means of transport which would be significantly friendly to the environment. Alternative fuel sources would also play an effective role in the reduction of pollution. This recommendation assumes that the alternative fuel type will displace a similar amount of current fossil fuels. It does not consider consumer acceptance or infra-structure issues that will impact the market penetration of these alternative fuels. Implementation of these recommendations would bear a total cost of about $16.2M and is well within the confines of the City Councils Budgetary allocations on tackling environmental issues. Decision-making about environmental issues necessitates the maintenance of a fine balance between the effectiveness of measures and the public reaction towards them. This simply means that in as much as the recommendations tend to curb and reduce the effect of environmental pollution, it might come off as inconveniences to the general public and thus   promote a negative reaction from the people of the city. The implementations and measures no matter how effective will put a strain on the convenience of the public, regardless to say that such measure will be beneficial both in the short run and long run.
