Skin allergy Research Paper Example | Topics and Well Written Essays - 750 words

Skin allergy - Research Paper Example Urticaria or hives is an itchy rash, due to hypersensitive reaction by the skin (Linscott, Emedicine). The condition may be acute or chronic and there are several variants to this condition. Itching can occur without any rash and may be due to some disease related to that part of the skin. Even some medications can cause itching. As far as atopic dermatitis is concerned, the cause is actually unknown. However, several researchers have attributed genetic and environmental mechanisms to the development of atopic dermatitis. Factors which contribute to the development of atopic dermatitis are infection, poor hygiene, extremes of climate, food antigens and aeroallergens (Kraffchik, Emedicine). Several chemicals sensitize the skin and cause allergic contact dermatitis. Some of the important chemicals are poison ivy, Nickel, rubber gloves, p-phenylenediamine, dyes, formaldehyde, wash and wear chemicals and preservatives (Hogan, Emedicine). In urticaria, the cause is unknown most of the times. However, ingections, foods, stress, drugs, exposure to certain temperatures and climates and exposure to latex can trigger the development of the condition (Linscott Emedicine). In atopic dermatitis, the pathophysiology is poorly understood. However, it has been thought that sensitization of IgE and epithelial barrier disturbance secondary to some kind of immune dysfunction is the cause for the allergic rashes. Another important defect attributed to this condition is defective epithelial cells contributing to defective barrier mechanism (Kraffchik, Emedicine). The main immune disturbance is imbalance in the T-lymphocytes with TH2 cells dominating the system and causing release of cytokines like granulocyte macrophage stimulating factor and interleukins 4,5, 12 and 13. All these amount to an increase in IgE levels and fall in interferon gamma levels. In those with chronic

Communications Best Practices When Identifying Critical Infrastructur Research Paper

Communications Best Practices When Identifying Critical Infrastructures - Research Paper Example Public service agencies communication airwaves have inherent device connectivity challenges that must be overcome by an installation of a communication system that is capable of averting the challenges. The best connectivity infrastructure must be flanked by the general outline of the systems used in a region. Interference of communication lines by the relevant public safety agencies must be reduced to negligible levels, to facilitate an around the clock service delivery and at an emergency handling capacity. Wireless communication spectrum in use by the communication system in lace must demonstrate a capacity to handle the various safety surveillance systems without running out of reach. Wireless bands in use by various public safety services officials must create an internetworking capacity that is handled by the principle of interoperability discussed below. Using the CARVER matrix in the infrastructure level of safety assurance, it is possible for emergency handling systems to avert various deficiencies. The acronym represents six vital features that must be in place to contain disaster risks. Criticality, Accessibility, Recuperability, Vulnerability, Effect and Recognizability are used in various applications for systems analysis for the relevant application in question. In public security service agencies, the matrix is used to calculate the level of risk exposure to various dangers that face the system such as public buildings and other infrastructure. Corresponding application of the matrix values allows the assessment to formulate response options using the infrastructure’s capacity to handle the identified risks. Using the values, the infrastructure in question can be evaluated and weaknesses obtained thereon used to design and implement the appropriate response capacity that is missing. Interoperability in safety communica tion systems is a conglomeration of the best disaster response program, by facilitation of the appropriate connectivity to allow efficiency in managing disasters.  

Imax case study for Strategic Management course Essay

Imax case study for Strategic Management course - Essay Example and Strength-Weaknesses-Opportunity-Threat models, this study will analyze the environmental factors that could affect IMAX’s performance in domestic and foreign markets. Using a crystal clear image which is almost ten times bigger than what a traditional 35mm movie theatre can offer, IMAX is known for its ability to offer exciting film formal around the world. With IMAX’s 3D screen using state-of-the-art 3 dimensional glasses combine with its 15,000 watt digital surround sound system, IMAX was easily able to capture the market. As a sign of success, IMAX was able to generate a total of $59.12 million revenue from IMAX system sales of which $36.57 came from films and $16.58 million from theatre operations (p. 3). Despite the success of IMAX in terms of capturing a larger part of its target audiences by introducing the state-of-the-art technology in the U.S. market, the company had to face business challenges because of its past growth strategy. With the purpose of capturing a wider scope of audiences, expanding the business by entering in alliances with commercial movie theatre owners like AMC, Cinemark, and Regal was not a good idea. Although IMAX was able to install the IMAX system in the multiplexes of AMC, Cinemark, and Regal was cheaper as compared to the case when IMAX would invest on building their own cinemas, the crisis that hit the theatre industry back in the late 1990s made the growth strategy of IMAX a failure (p. 6). As a result of financial difficulty on the part of the theatre owners, many were left out with no choice but to file bankruptcy. This left IMAX with a long list of financial debts. To enable IMAX to success in the global theatre industry, the company had to make a clear judgement and careful decision on how IMAX will be able to compete with its rivals without having the need to experience the same business failure that took place back in the 1990s. Upon analyzing the IMAX’s general and industry environment specifically by

Employee Relations Research Paper Example | Topics and Well Written Essays - 1500 words - 1

Employee Relations - Research Paper Example It is recommended to consider the employees as valuable assets and make them spend time on telecommuting. A flexible work schedule can also be introduced in the company to increase the morale of the employees (Time Inc, 2013). It was also viewed that the products produced in the company were low in quality because of which it was facing severe problems. Thus, it is considered that the company should establish certain goals related to quality in order to measure the manufacturing process of the organisation and the outcomes of the manufactured product. It is also recommended to focus on the initiative of improving the outcomes of the manufactured product that would help Philips to obtain recognition in its new plant of Manila. Besides, administrators functioning at the new plant should ensure that they provide their expertise of guiding and consulting the workers in their respective departments to make certain that the workers achieve their targets and the quality and the overall perf ormance of the workers are improved. In addition, it is very important to classify the potential opportunities for improving the quality of products by constantly monitoring the work performance and ensuring that the standard and quality of the goods produced meet the expectation of the customers along with providing them optimum satisfaction. It is also very essential for the administrators to design a system that is very efficient as per the work requirements so as to implement initiative for improvement which would directly.

Investment & Private Banking Essay Example | Topics and Well Written Essays - 4000 words

Investment & Private Banking - Essay Example In this era, corporate issuers search for any form of low-cost funds and then use the derivatives market to alter those claims in a risk profile that cater the financing needs of the corporation (Bethel & Ferrell, 2006). The increased use of derivatives has given sophisticated institutional investors a way to attain risk exposures that they desire and the ability to manage their existing risk exposures in a dynamically cost-effective way. Derivatives are increasingly becoming more and more accepted in the financial markets with competitive prices and margins. But the margins earned by the institutions are declining and thus they have began to engineer more complex securities known as structured products. As the derivatives became more advanced, corporate as well as private investors wanted to protect their downside as well as upside participation in the bear market and bull market respectively. This paved the way for a new kind of derivatives called the structured investment products or structured finance products (Bethel & Ferrell, 2006). Structured products have no exact definition in the business or in the regulatory framework. Definition used by SEC, NASD and NYSE for structured products is that it is an instrument or security that is derived from another security, index, commodity or basket of commodities (Bethel & Ferrell, 2006). This is a broad definition that includes a wide range of products such as equity linked, collateralized debt obligations, credit-default swaps, commodity-linked debt and reverse convertibles. For this reason, according to Hens & Reiger (2009) structured products are also called equity linked or index linked notes that combine one or more assets such as stocks or bonds with a derivative providing a bundle that have specific characteristics for different investors like participation and protection of capital.

Understanding ecohydrological processes for sustainable floodplain Term Paper

Understanding ecohydrological processes for sustainable floodplain management - Term Paper Example The important worry is about the water scarcity in the atmosphere of ever growing population. The fundamental aspect is water is necessary for every vital biological activity and food production also gets affected in the context of water scarcity. According to Tolba, Mostafa (2004) mankind needs three times the present amount of water used for irrigation, to produce the food necessary for feeding additional population in the next 50 years. Hence, in the first step to get additional water for food production for the future, the additional water resources should be explored.In the next step, the additional water resources explored should be protected by allowing certain ecological processes that maintain water content on the planet. The fundamental aspect in the above suggestion is about the protection of ecohydrology that needs global dialogue on water for food and environment. To make ecohydrological processes sustain in future, the protection of ecological systems, hydrology and wat er management should be done on global scale, so that every country in different geographical area can share the endeavors of ecological protection. As water is blood stream of biosphere and global industrial development is destroying that blood steam, the protection of ecohydrology without disturbing the industrial development should be discussed. In the context of point of no return, the concept of sacrificing the industrial development for the sake of ecohydrological systems can be explored. However, as the industrial development is also crucial for economic development of mankind the utilization of comforts and the affect of that on the ecological systems can be explored for finalizing the steps need to be taken for the protection of environment. 1 Objectives The objective of this paper is to explore the concepts and aspects that help in preserving the bio diversity thus resulting in restoration of water resources. The extent of presence of greenery indicates the assimilation of CO2. Hence, the presence of vegetation decides the content of CO2 present in atmosphere that helps in global warming resulting in decrease of water resources. So, the main objective is to plan forestation in different parts of the world that can neutralize the global warming to protect or restore water resources. In addition to that the thermodynamic relationship maintenance should be an important objective to neutralize effect of industrialization on water resources. The water resources can be replenished or restored when the liquid and vapor phases reach saturation conditions at regular intervals and sustain up to substantial periods. The change of atmospheric state at the saturated surface should occur periodically every year and those regular intervals is nece ssary for protecting water resources required for mankind as well as industrial development. However, to attain the above point of saturation at maximum number of places on the plane, the extent of usage of water and natural resources at each geographical point in the planet is necessary to restore the necessary vegetation that results in vapor liquid saturation that helps in maintaining and protecting water resources. Another important aspect in restoring water resources used up due to industrial development is protecting and increasing under ground water resources that grow due to percolation of water into the soil. The percolation component decides the capillary rise or fall in water table at a particular point. Hence, the surfaces that allow percolation of water into the soil should not be decreased thus maintaining the capillary rise in water table a constant process. 2 Another objective in this paper is to explore the methods and knowledge of preserving food plain

Congenital Erythropoietic Porphyria Research Paper

Congenital Erythropoietic Porphyria - Research Paper Example CEP, or congenital erythropoietic porphyria is an autosomal recessive trait, which causes the patient to have an enlarged spleen and liver, reddish urine, bones and teeth as well as lesions on the skin that react to UV light due to the excess porphyrin deposits (Bishop et al., 2010, p. 1062). However, another disease, AIP or acute intermittent porphyria could pose as CEP due to some similarities in patient symptoms. Initially, patients that were affected were suspected to have CEP since there were the usual symptoms such as the reddish discoloration of teeth as well as the urine, and pink fluorescence of bones under UV light due to deposition of porphyrin and other precursors (Clavero et al., 2009, p. 585). However, if molecular and tissue analyses would be employed, CEP and AIP can be differentiated from each other, with CEP being an autosomal recessive disease and AIP a dominant one. This paper would be about some studies on congenital erythropoietic porphyria (CEP), as well as som e descriptions of the disease at the genetic level. The first main topic is about the molecular aspect of CEP as a disease. The most common form of mutation of the UROS gene located at locus 10q25.3-26.3 is the C37R mutation, which is fairly common. Other mutations such as non-sense mutations, splicing in certain cites, deletions and insertions as well as other complex rearrangement of sequences at chromosomal locus 10q25.3-26.3 occur and create the CEP phenotype (Bishop et al., 2010, p.1068). In a study on the expression of CEP model expressions in mice, Bishop et al. (2011, p. 751) were able to quantify the approximated enzymatic activities of the UROS enzyme in livers of normal mice and CEP-affected mice. It is hypothesized that since mice are animals with shorter lifespan and thus have several generations in a short period of time, the causative mechanisms of the defective UROS gene would be easier to identify. Also, since the disease would be following the Mendelian Pattern, be arers of the homozygous recessive genotype would show disease symptoms while heterozygous and homozygous dominant would be fairly normal. Meanwhile, in a study about CEP in cats, a publication regarding the discovery of a feline model for CEP was released (Clavero et al., 2010, p. 382). Compared to a previous study, which had cats with AIP instead of CEP, the new proband for this study had PBG and ALA levels which are in normal detectable amounts, with elevated URO I and COPRO levels as well as abnormal UROS activity, much like in human and mice CEP counterparts. Via amplification of the suspected mutated sequences, aside from a shorter polypeptide (one cystein shorter), feline UROS sequence was fairly similar to the previously reported human and mouse. The double-mutant had reduced enzymatic activity, caused by two amino acid substitutions, making the protein product unable to fold in a stable manner, thereby causing reduced activity of the mutated enzyme, as compared to either sin gle mutant or normal enzymes (Clavero et al., 2010, p. 387). Three genotypes were produced after mating several strains and generations of mice: homozygous recessive mice having the CEP gene had a genotype of C37R/C37R, a heterozygote C37R/V99L expresses a milder form of the disease, and a homozygous dominant genotype V99L/V99L exhibits the normal phenotype. Blood sampling for analyses of presence of porphyrin and other precursors were done, as well as histology of the liver and the spleen
