The main uses of Ultrasound in an imaging department and a vascular department - Essay Example o Sandhu (2007), ultrasonography can image soft tissues such as muscles, blood vessels and so on and can also monitor needle position while the interventional procedures. In anesthesia setting, ultrasound is the best choice due to the compactness of the instrumentation, easy transportability and lack of damage to tissues (Sandhu, 2007). In the imaging department, ultrasound is also useful for determining neuaxial blocks in people especially children. Ultrasound imaging for determining transthoarcic and transesopheageal echo-cardiography is utilized to diagnose cardiac anesthesia, trauma anesthesia and order cardiac function abnormalities that arise either during the perioperative period or intensive care settings (Sandhu, 2007). Forsbery et al. (2002) argued in its research paper that imaging modalities such as MRI and CT have well established 3D data displays and therefore are being used increasingly in the diagnostic decision rather than ultrasound. This is because the time available for acquirement and processing of 3D data is limited in ultrasound imaging. For example, in Doppler ultrasound, blood flow data is obtained using multiple firing methods. Accordingly, improvements in the computer processing technology and visualization methods, the clinical use of vascular 3D ultrasound has increased. The clinical uses of 3D ultrasound include evaluation of the flow in the carotid artery, kidney, placenta and others (Forsbery et al., 2002). The advantage of the 3D ultrasound is that the doctors can localize a functional abnormality that is relative to primary anatomy. Other advantage of 3D vascular imaging is that ease that is involved in the segmentation of data flow from the tissue echoes (Forsbery et al., 2002). Thus, as a result, ultrasound imaging in the imaging department has become successful as it provides â€Å"noninvasive, 2D as well as 3D images of soft tissues and blood flow without ionizing the radiation† (Forsbery et al. 2002). Ultrasound is also

A South African Investment - Essay Example While comprehensive civil rights as well as freedom are critically imperative to all people in order that they can realize their absolute potential and assert their appropriate place in humanity, there are other, supplementary fundamental needs that ought to be satisfied prior to a person worries about spiritual, intellectual and related individual freedoms and rights. It may not be reasonable to offer an individual full government, social, as well as legal rights if they are deprived any reasonable sources of livelihood (Mbendi, 2008). Caltex had the power to influence political policies on the South African government in order that the government may revive its laws. This has happened in other parts of the world, whereby conglomerates influence government policies in order to create a conducive environment for business. Foreign financial investments mean a great deal in any country since it revitalizes the social-economic status of the population and the national economy as well (T obin, 2009). It is an ignominy that Caltex had no problem investing in a country whose laws were exceedingly abhorrent to humanity. In contrast it is factual that in that era, the living standards of the South African minorities as well as the Blacks were in a deplorable state. They vast majority of these populations lived in pitiable homes, and had poor access to high quality educational programs. They were also deprived the right to practice certain jobs or careers, and granted wages that were exceedingly less than that of the white population in South Africa (Nicholas, 2008). For numerous South African Blacks at the time, for whom so several outside the nation had the courage to confront the repressive regime may have chosen to take up jobs at the Caltex plant which granted them better living wages and better workplace environment than in the civil service. It is justifiable to imply that absolute freedom may not have been the priority for all Black South Africans who needed bett er living standards. Therefore, the Caltex plant may have been the category of investments that were essentially required in the country at the time. The only provision Caltex ought to have added would have been the maintenance of reasonable wages and reasonable housing for its black and colored human resources (Mbendi, 2008). Question 2. As a stockholder in Standard Oil or Texaco, it would have been appropriate to vote in agreement with the three stockholder declarations. While it is factual that under the utilitarian philosophies, it might not of necessity have been the most appropriate option for Caltex, Standard Oil or Texaco to desist from investing in South Africa. As a stockholder, it would have been appropriate to vote according to individual conscience. Any financial recompense, such as facilitating the generation of national income from the mining of natural resources or construction of national industries such as in petroleum, appears as unconscionable in regard to the fu ndamental premise on which the South African government operated and survived (Nicholas, 2008). The first resolution demanded that Caltex terminates all its operations in South Africa unless and until the government ceased
