Introduction

The cheetah ( Acinonyx jubatus) is the fastest land animal with a widely quoted speed of 71 miles per hour or 32ms-1 however time trials under controlled circumstances show that the top speed is somewhere around 29ms-1 or 64 miles per hour (Sharpp, 1997). The Cheetah is uniquely adapted for speed and very few other land mammals can boast of such physiological specializations. Cheetah is a member of the group Felidae and they are unique in many ways. To start with, the African cheetah is the only species in the genus Acinonyx. Out of the 37 species in the cat Continue reading...

Stress can occur to any human being. Stress is a normal psychological and physical reaction to the demands of life particularly to traumatic incidences. The process of induced abortion or natural is a stressful time for many women (Adler, N. E., David, H. P., Major, B. N., Roth, S. H., Russo, N. F., & Wyatt, G. E. 1990, p. 41). The stress can occur before and after abortion. In this study we are focusing only on post abortion stress. Women who undergo abortion natural or induced are likely to experience acute stress i.e. Acute stress originates from the demands and Continue reading...

The Book Part

Michele Alexander covers the issue of racialism in the modern society. Though the media claims that the modern American society has moved past the racism era, racism has taken a modern form in terms of the social policies that the government implements. Through these social policies, members of different races receive different conviction for the same offenses. These social policies present the transformation of racism. Obama’s victorious election into presidency may have depicted the end of racism, but society perceives it differently.
The social policy on the drug war presents the real image of modern racism. The criminal Continue reading...

Introduction
In his article, John Derbyshire wrote about the challenge of improving the children’s academic performance. He documented that a few years ago, New York City Mayor took the Rand Corporation’s service in raising the students of public schools’ examination score by providing cash bonuses for those teachers who will have an improved class. As he continued with his article, Derbyshire used different styles in writing to persuade his readers. Based on his attempts to persuade his audiences, rhetorical strategies were used such as logos, ethos and pathos. However, there were clear manifestations of logical fallacies in Continue reading...

Trained medical professionals attend to patients of diverse ethno-cultural backgrounds, different age groups, different sexes, as well as patients with different educational backgrounds something that that makes communication between them more multifarious and difficult. Professionals in this field are required by law that they increase their communication competencies in culturally diverse healthcare contexts, where the cultural diversity of patients and staff challenges the professionals in the field. It is believed that the intercultural lens is appropriate for understanding the issue of intercultural communication, which usually involves miscommunication in hospital settings (Coiera and Tombs, 1996). The refresher course the medical Continue reading...

The report talks about the importance of controller tunings in controlling industrial equipment. According to the report, controller valves are important in controlling the flow rat, the amount of input in machinery and also the amount of output of the machine. The importance of the controllers can be seen in controlling a water cooling machine in which case a slow controller would be inappropriate to be used. The importance of a feedback controller on the other hand is the essence that it enables the determination of an error that may occur between a set point and the process value Continue reading...

Estimates show that, in the U.S., about 41,000 cases of central line-associated bloodstream infections (CLABSIs) occur in hospitals each year (CDC, 2014). CLABSI is a preventable complication that lengthens the hospital stay and increases the cost of care. It is a cause of patients’ lost productivity and undue suffering. Since 2008, the Center for Medicare and Medicaid (CMS) has also refused to reimburse CLABSI-related care. The negative implications for the patient and the organization call for prevention using evidence-based practice (EBP).
Accessing the hub of peripherally inserted central catheters (PICCs) is a common source of infection (Moureau, 2010). Continue reading...

Partisan Polarization in United States

Introduction
This paper will support the ideology, that political partisan polarization in the United States, usually causes inefficiently and uncertainty in policy making. Not only because of the unusual significant levels of ideological polarization, among lawmakers or voters that produce very large variance in policy making. Reasonably, the problem of extreme gridlock in a unique form of two presidential party democracy in which the status quo changes frequently thus, requiring defections from the opposing members of legislation (Lawrence, 2010). This study paper will evaluate the argument that it is hard to achieve these defections, not because of the increased Continue reading...

Introduction

The purpose of this experiment was to observe collisions between two carts, measure energy changes and classify the collisions. It was hypothesized the momentum would be conserved during the collisions.

- Consider a head on collision between two billiard balls. One is initially at rest and the other moves towards it. Sketch a position vs. time graph for each ball, starting with the time before the collision and ending a shot time afterward
Before collision, ball 2 moves with a constant velocity towards ball 1. Therefore, its position changes with time while the position of ball 1 does not Continue reading...

Abstract

The experiment is aimed at constructing a step-up transformer. This is due to the type of materials being used and the number of rolls that the wire is rolled on the U-shaped material. This can easily be related to the alternating current that is tapped from one source to the other. This current can easily be measured in respect to the size of the voltage that is alternated in between the primary transformer and that of the secondary transformer. The number of coils in the primary material is two; the other secondary coil has four coils. The material used Continue reading...

Conditioning in Psychology refers to the processes by which repeated stimulus produce predictable and frequent response. There are two types of conditioning namely classical and operant conditioning. Classical conditioning was discovered by Ivan Pavlov during his digestive system research (Kalat, 2011). Pavlov noticed that the dogs salivated whenever they sighted attendants dressed in lab coats. He attributed this behavior to the repeated exposure of both food and lab coats to the dogs. Pavlov investigated the behavior by ringing a bell whenever he was presenting food to dog. After repeated occurrences, he observed that the dogs could salivate when the Continue reading...

Methods of Heat Transfer

Conduction
The first method through which heat is transferred from one object to another is conduction. Conduction occurs in liquids and solids through transfer of kinetic energy present in one particle to the immediate particle(s) in its surrounding. By considering the bonds existing between atoms and molecules in solids as elastic links, the vibration of one particle due to increase energy level caused by heat, the next in its line vibrate too. This process is replicated in adjacent particles thereby allowing transfer of thermal energy from a body with a higher temperature as compared to the one with Continue reading...

Before the advent of the computer, artists and artisans alike utilized a complex tool in making their letter forms; the hand. At ten digits, five for each hand, the hand was efficiently the first digital lettering tool, utilized in engravings, carving and in the production of the various letter forms. The hand, while allowing for a few technological flaws and eccentricities, still facilitated the creation of some of the most beautiful lettering forms ever made. The advantages of the hand as a lettering tool underscore the paradox that, with technological advancement, both a loss and profit were incurred. The Continue reading...

Polio: An American Story is a scholarly book written by David Oshinsky, a historian from the University of Texas, examines American medical research in the 20th century where there was Polio epidemic. Poliomyelitis is a dreadful disease that has claimed a lot of lives before the discovery of a vaccine. Though children are considered to be more prone to getting the disease, adults could also be infected with polio. This means that no one was excluded from attaining an infection despite their age, gender, or class. Oshinsky writes, “Polio hit tidy and stable neighborhoods harder than the areas marked Continue reading...

Introduction

Initially there were beliefs that, MMPs are jointly able to degenerate all constituents making up the extracellular matrix (ECM) together with basement membrane that confines their operations to tissue reconstruction as well as the preservation. Nonetheless, the contemporary studies also signify that MMP-1 is responsible for controlling the production or else the activation of the chemokines. At this point, it is critical to understand that MMP-1 is among other MMPs.
Similarly, the knowledge holds it that MMP- 1 cleaves a peptide bond beforehand a residue comprising of a hydrophobic adjacent chain, for instance Met and Leu. The other sideways Continue reading...

This paper proposes to look at Amiri Baraka’s poem ‘Black Art’ and analyse the effect of the nocous language, the rhetorical severity and incendiary polemics implicit in the verse. The paper attempts to analyse the construction of the poem that is considered representative of Baraka’s Black Aesthetic, and delve into the chronical of controversial radical dissent and nationalist stance which constitutes the rubric of ‘Black Art.’ In attempting to delineate the above, the paper in the turn of its denouement, wishes to foreground the much-contested choice of form and style, and whether the chosen deployment serves to Continue reading...

There is a time when advertisers need more than descriptive research to understand consumers current behaviors and attitudes. They sometimes require an understanding of cause and effect, which is obtained through experimental research in which an advertiser alters something in the consumer’s environment, or product in order to see what would happen. The goal of an experiment is usually to determine the effect of changes in one area on one or more other areas. An experiment is used to vary the amount of advertising placed in particular markets to determine how advertising weight affects target audience, advertising awareness Continue reading...

In psychology, there is a learning theory that states that as we learn, we adjust the manner in which we perceive our environment and the manner in which we interpret the incoming stimuli. Consequently, all this alters the way we interact, or behave. It is from this theory that one learns about behaviorism. The latter is the study or our behaviors after exposure to given stimuli within the environment. This helps us in understanding the effects given stimuli have on us.
In the learning theory, we have classical and operant conditioning. In classical conditioning, one learns to associate one Continue reading...

The media is a powerful thing in today’s modern world. No matter where we go, it seems there is always a screen in our face. We have the ability to watch television shows, movies, and advertisements from any device imaginable. Whether it is from the comfort of our living room sofa, watching on our big screen television, or from a chair in a quiet coffee shop, watching from our small cellphone screen, we carry the media with us wherever we go. While this may seem like a luxury and a comfort, at times it can be negative. This Continue reading...

Research is critical to the advancement of any field, whether it is engineering, medicine or even management. However allowing researchers to conduct experiments without any supervision or without checking in with some regulatory authority might put them and others around them at risk. The premise of this paper is to argue that research regulation is necessary to ensure that civil rights of those involved with the experimental safeguarded.
In the five case studies that were outlines for review, one common factor among them was that in cases when researchers were given freedom to perform experiments they put the results Continue reading...
