In a pure liquid, water molecules can move freely in all three dimensions whereas it is not possible in case of tissues. Conventionally, T2-weighted MRI images were used to identify muscle strains. These MRI images were capable of optimising contrast between injured muscles and normal uninjured muscles. Recently, the DTI was invented as a more accurate method for identifying muscle damage as compared to the T2 weighted MRI. The DTI variables exhibit a strong and quick response to damage whereas the T2 signal may take a prolonged period to respond to the change. According to a recent research conducted in the United States, “diffusion tensor imaging based muscle fibre tracking enables the measurement of muscle architectural parameters, such as pennation angle (theta) and fibre tract length (L(ft), throughout the entire muscle” (Acton, 2011, p. 949). Experts opine that the DTI technique can be effectively deployed to examine the three dimensional architecture of the skeletal muscle and get exact information regarding muscle damage. The DTI based muscle fibre tracking method has the potential to reconstruct muscle architecture and, hence, it can be considered as one of the most potential inventions of medical science. As Sinha and Sinha (2011) point out, one of the most significant advantages of this technique is that the diffusion tensor images have the potential to support larger volume imaging without centring and repositioning the magnet value. In case of elongated structures like muscle fibres, the diffusion coefficient of water is higher along the fibre. By taking diffusion measurements in at least six directions, it is possible to calculate a diffusion tensor and which in turn would be beneficial to extract the main direction of the diffusion. Subsequently, this directional information can be integrated into neighbouring pixels to facilitate fibre trajectory reconstruction. In the view of Heemskerk, (2009), this process is helpful to estimate muscle architectural parameters including fibre length, pennation angle, and psychological cross sectional area. In addition, the DT-MRI muscle fibre tracking is a potential method to take pennation angle measurements of human muscle. The DTI based muscle fibre tracking technique is still at its developmental stages and this process offers greater future scope. MRI techniques for cartilage imaging Recently, a number of advanced MRI techniques have been developed with intent to facilitate more accurate imaging of cartilage. Major MRI techniques for cartilage imaging include hip imaging, parallel imaging, delayed gadolinium-enhanced MRI of cartilage (DGEMRIC), high resolution MRI, sodium MRI, T1p relaxation, and T2 relaxation. Most of these methods are very effective in applying cartilage imaging. Hip imaging is specifically demanding due to the joint’s spherical nature, thin articular cartilage, and deep anatomical position (Kim &amp. Mamisch, 2008). As Hitt and Meel (2009) point out, this technique is mainly used for the examination of the acetabulum and acetabular labrum. Hip imaging is generally acquired in the specified ‘axial, coronal, and sagittal planes’ (ibid). The hip imaging technique will provide ‘true parallel slices of the acetabulum, acetabular labrum, femoral head and neck, and trochanter anatomies’ (ibid).

If Cash accepts, Jordan should try and collect the required data from the area Cash was assigned and try to compare them with the Cash’s computed data. If the date comparison seems to be correct, Cash should steal be reported to the head of the department to be fired from the project. Citing article 2b of the Principles of Professional Responsibility. that is, given that the project was to have direct public application policy formulation, Cash had neglected his duty to the project as well as to the public. Article 2b states that “an anthropologist should not knowingly falsify or color his findings”(Cassell & Jacobs, pp. 34). If Cash is not fired because of the similarity on the data collected by him and those collected by Jordan, Jordan should develop arrange for database verification in Cash’s region.

Two students should be hired who will interview all information reported by Cash. These interviews results will be stored in a separate file until the completion of the projects field portion. At the analysis time, the data collected by Cash will be compared to that collected by the students in the same region. If there would be a difference in the two data, this will be an indication of falsified data by Cash. The student’s data will be used to replace Cash’s one and he would be requested to return all the payment made to him which he won’t reject as there is enough evidence to support that.

Once the situation had developed, Smith had little recourses. The direct argument with the adviser was not the best option. Chances were high that he may just laugh at Smith knowing that there was no proof to support that. The adviser is one of the staffs in the university, getting of support for Smith from the department could be tough. This is because this will portray the department as having being involved in plagiarism.&nbsp.

Need an argumentative essay on Discuss how recent changes in the law may impact on the tourism and hospitality industry. Needs to be 7 pages. Please no plagiarism.

A series of constraints can appear causing severe delays to the completion of the relevant projects.

Current paper focuses on the effects of law on the airline industry – emphasis is given on the aviation law of UK – as influenced from the European Union law. It is concluded that the update of legal rules related – either directly or indirectly – to the airline industry has affected the performance of the specific industrial sector. The character of the relationship between this industry and the law cannot be clearly specified – being characterized by benefits and drawbacks. However, despite the delays that the changes in the law have caused to the development of airline industry – in the context described below – still, it is necessary that the relevant measures are supported both by the entrepreneurs and the public. After a transition period, the benefits of these initiatives will be made clear – even if currently the introduction of the relevant legal rules is not fully justified.

The needs of various industries in regard to their regulation can be differentiated. The characteristics of each industry and the level of its interaction with the public are usually of high importance in order to decide on the form of the regulatory framework developed for the particular sector. Under these terms, the needs of each industry in terms of law are defined by the following criteria: a) the position of the industry within the local economy, b) the structure of the operational activities of the industry’s firms, c) the practices followed in regard to the regulation of similar industries in the context of the international community, d) the rules developed by international bodies and which are binding for a specific industrial sector – for instance the rules of the European Union which need to be promoted within all member states.

In the case of the airline industry, the elements of the legal framework used for the

Need an argumentative essay on Discuss the effectiveness of legislation regulating child employment in Britain. Needs to be 3 pages. Please no plagiarism.

There is a problem area that will be touched upon, which is whether the legislation efficiently deals with children who are left to care for a family member.

The first factor of legislation that UK has instituted is to promote education. therefore creating a skilled workforce and ensure sufficient rest. therefore children CANNOT work before 7am and after 7pm.3 The main piece of legislation that deals with child employment is the Children & Young Persons Act 1933. Also children that are under 13 cannot be employed at all, even in a family business. Children from the age of 13 to completing their GCSE’s can only work part-time, because education is paramount. If an employee is 13 or 14 they can only work in 9 specific types of employment. whilst at 14 or 15 they can work in any form of employment.4 Finally, the legislation also ensures that the work conditions and type are risk assessed for the child employee according to the Management of Health & Safety at Work Regulations 1999. This illustrates that in traditional forms of employment the child is sufficiently protected, including being employed in the family business.5

The problem with legislation that regulates children’s employment is that it does not effectively address the problem of child carers6. rather it effectively deals with traditional forms of employment.7 There needs to be effective reform to protect the child who behind closed doors is effectively employed as the child carer. One could say that the current legislation does protect the child, because they cannot be in the employment of parents. however how can caring for a little brother or sister or even a parent be classed as employment?8 It is easy to identify if the person who is being cared for is receiving carer’s allowance and there was no identifiable adult carer that they are paying. therefore

Need an argumentative essay on Discuss the importance of adhesion molecules in health and disease. Needs to be 6 pages. Please no plagiarism.

They participate in the recruitment of neutrophils to the site of inflammation in a dynamic and multiple-step manner. Different families of adhesion molecules participate in leukocyte’s localization dynamics: selectin family and their ligand participate in the rolling phase. integrin family and their ligands mediates the activation and firm adhesion of leukocytes to the endothelium. both selectins and integrins participate in trans-endothelial migration. Inflammatory and immune responses are important in host defense but on the other hand they can also generate pathological inflammation in a variety of conditions. Several illnesses characterized by acute inflammation with infiltration of neutrophils are in most of the cases associated with augmented expression of selectins (E-selectin and P-selectin), while ICAM-1 and VCAM-1 expression prevails in chronic conditions (Etzioni, 1996). Furthermore, enhanced local expression and increased amount of serum-soluble adhesion molecules have been reported in atherosclerosis, ischemia-perfusion injury, acute lung injury, rheumatoid arthritis and graft/organ rejection (Bevilacqua et al., 1994).

Asthmatic symptoms have been linked to specific cytokines (IL-4 and IL-5) which are produced by CD4 T helper cells. CD4 helper cells are not only the major lymphocyte responders in an allergic response, but also the cells responsible for the memory of an allergen. Very Late Antigen 1 (VLA-1) and VLA-2 are two adhesion molecules (integrins) implicated in the attachment of CD4 T helper cells to the extra-cellular matrix of the lung during allergic asthma. The expression of these adhesion molecules is thought to be of vital importance in the capability of the immune system to react against allergens. Thus, in people without asthma normal adhesion of CD4 T helper cells will help the organism to react against a dangerous antigen, but in asthmatic patients the inhalation of a harmless
