In this case, there is a report of a mysterious outbreak which has affected a dozen people with one in critical condition and one fatality. All involved are said to have attended the same event, and they developed symptoms almost 24 hours later. Symptoms of the affected have been presented. Nobody appears to know the cause of the outbreak. To find answers and solutions to these problems, some questions need to be asked and answered. The World Health Organization (WHO) recommends some of the questions asked should include demographic details including occupation, clinical details (onset, symptoms, severity, and duration), ...

Introduction Gene therapy is a genetic technology in which genes and nucleic acids (RNA or DNA) are used for the cure, treatment, or prevention of a disease. This technology can be accomplished by replacing a defective or mutated gene with a healthy copy to reduce the problem; removing or inactivating a mutated or defective gene to reduce or eliminate improper functioning, and/or introducing a new kind of gene in the body to help in the fight against disease. Initially, the technology was used for orphan diseases such as primary immunodeficiencies, but with the passage of time, ...

Introduction

The interest groups are extremely powerful in the Western countries as the source of the representation of the population in the political life of the country. In the contemporary society the shifts in the political arena of the communities are made as the result of the actions of the interested groups. These groups represent the formation of the citizens having the leverages for the exercising influence over the population. They have the power and opportunity to control the spread of the political ideas and behavior among the population. Meanwhile, the political life of the Western democratic countries is not ...

The Pythagorean Theorem can be used to solve numerous real world problems involving right-angled triangles where the lengths of at least two sides are known. One of the areas the theorem can be applied is in construction by painters. Since painters use ladders to reach high walls, the Pythagorean theorem would assist them in determining how tall their ladder should be in order for its base to be safely placed away from the wall such that it is stable and does not tip over. The walls are perpendicular to the ground, and the ladder is a hypotenuse, and this ...

Question 1

Information is an important asset. The core goal of information security is to protect the availability, confidentiality, and integrity of the information. To build a secure organization, it is important to build a security program that protects the information assets of the organization. An important part of the security program is the risk analysis. The objective of a security program is to mitigate risks, which does not mean eliminating them but reducing them to an acceptable level. To ensure that the right kind of security controls are in place and controlling the risks effectively, it is necessary to anticipate ...

1) Population growth and overpopulation is one of the major problems of every developing country. The factors that influence population growth are: a) Women getting married at early ages lead to a high birth rate. b) Provision of health benefits to children, women and the elderly have contributed to decreased mortality rate, and thus increased birth rate. c) Lack of family planning contributes to increased birth greatly. According to census, The United States population as on June 11, 2016 is 323,747,258 with one birth in every eight seconds, one death in every seconds and one international migrant ...

The use of grammar offers a better understanding of the language to the small learners. The use of pictures to aid in the learning process for small children also offers a better understanding because it draws the attention of the students towards the learning materials. Grammar helps people, and especially the learners to interpret the various meanings presented by any material in a given cultural setting (Rushton, 2011). The level of the teachers’ level of knowledge of any language is of very great importance to his or her small learners. In most cases, the grammar representation needs a higher ...

Analysis of Diseases

Overview Chikungunya (CHIK) refers to a re-emerging arboviral disease transmitted by the mosquitos Aedes aegypty and Aedes albopictus (Pialoux 318). The virus belongs to the genus Alphavirus and family Togaviridae. The word chikungunya derives from Makonde language (spoken in Tanzania and northern Mozambique), where it means “to walk bent over” (Halstead 557). This name refers to the main feature of both chronic and acute phase of the disease a change in posture causes by the arthritis and arthralgia (Charrel, Lamballerie and Raoult 769).

History

The disease gained its name after the outbreak in Tanganyika, the modern Tanzania in 1952. However, ...

Major Achievements in Biology

Researchers and scientists are always intrigued by biological processes and activities, and strive to utilize them for benefit of mankind. Antibiotics, monoclonal antibodies, vaccines and several therapeutic agents, high yielding as well as disease tolerant plants and animals are all results of extensive research in the fields of cell and molecular biology, immunology, biotechnology and genetic engineering. Treatment to several diseases, even genetic disorders are available today only due to breakthrough discoveries in biology. Three such important discoveries are revelation of structure of ribosomes through X-ray crystallography, identification of tumor specific antigens (TSA) expressed on the surface of cancer ...

Synopsis

In this experiment, AC circuits, capacitors, and inductors are reviewed. Circuit analysis to cover sinusoidal signals is done. The experiment is drawn from lecture 5 and six learned on series and parallel configuration of RLC circuits, that is, Resistor –capacitor, RC; Resistor-inductor, RL; series Resistor-Inductor-Capacitor; RLC; and parallel RLC circuits.

Introduction

The three basic passive components, resistor, inductor, and capacitor have varied phase relationships when connected in a sinusoidal AC circuit. Analysis of a series RCL circuit is similar to dual series RL and RC circuit. Series RCL circuits are categorized as second order circuit because they have two energy ...

Background information

Malaria, a mosquito borne transmissible disease of both human beings and some animals is a pertinent disease in the 21st century which accounts for more than 650, 000 deaths annually (WHO, 1147). The prevalence of malaria is highest in the tropical and subtropical regions. Adverse effects of the disease is an equally major public health issue that affects maternal and child health. In the developing countries, malaria is a leading cause of maternal and child health. Consequentially, it is a pertinent public health disease. This manuscript offers a succinct analysis of the disease while appraising its causative agents, life ...

Introduction

As the modern day business sees the emergence of new capital markets with enhanced relaxation over foreign capital governance and raised flexibility of stock exchange rates, it is very important for academicians and industry experts to derive a relation between the foreign exchange rates and stock market fluctuations. This information is a key component for the international investors so that they can effectively diversify their investments with an adequate hedging strategy. Also, understanding the true nature of interrelation between the stock market and foreign exchange is also a must for the financial policymakers so that they can try to ...

The DBIR 2015 is the ninth one from Verizon, and similar to the others, it highlights patterns and trends present in an aggregated incident data set. The report begins by emphasizing that there are few unique breaches in the cyber-world, and that the likelihood that an intrusion mechanism has been applied previously is relatively high. Furtherance, the DBIR informs against the presumption that victims of data breach believe they are in isolation; it is this falsehood that impedes on information sharing on attack patterns, which could collectively help prevent future intrusions. Verizon has managed to develop a classification for ...

Abstract

This is a review of a paper called, “Are Humans the Source of Canine Mange? From the journal Parasites and Vectors. I reviewed the paper and determined that the study was both accurate and sound. The paper hypothesized that humans were the main reason for the spread of Sarcoptes scabiei in dogs and other canines. The results indicated that humans were not the main carriers of Sarcoptes scabiei to dogs and other canines and that further studies should be undertaken.

Are Humans the Initial Source of Canine Mange? Is a journal article written by Valerie Andriantsoanarina, Fang Fang, ...

Introduction

Numerous electrical applications require an inverter, which converts Direct Current (DC) to Alternating Current (AC) power. Some of these applications require the stepping down of voltage levels when realizing this conversion, which signifies that the input DC power is greater than the AC power. Conversely, certain applications require the opposite: to step up voltage when performing the power conversion, which means that the input DC power is lower than the AC power. These requirements can be met through the use of Voltage Source Inverters and Current Source Inverters, respectively. However, some particular applications require to step down voltage for ...
