Abstract

This lab study was undertaken to analyze the effects of torque forces and shear modulus of rigidity on three circular solids namely, half-hard brass (60% Cu and 40% Zn), 0.1% and 0.4% carbon steel. This was done by subjecting the samples to a shearing stress and by noting down its angular displacement. The maximum torque of each sample was calculated and compared. Their polar moment of inertia was also calculated to assist in analysis. The value of shear modulus of rigidity of each of the samples was determined using a graph which related torque and angular displacement. It was ...

Introduction

Causes of Slow TAT Interviewing some of the students who have worked in medical laboratories as interns provided some insight into the reasons of slow TATs. One reason that appeared to be common was errors arising from other departments. Sometimes, clerical errors such as incorrect labeling of specimens lead to wrong tests being done on patients. Other times nurses bring specimens from an unacceptable source for ordered tests and drop them off in the laboratory without letting the staff know. Correcting such a mistake requires the nurse to return to the laboratory and fill out a form which results ...

Abstract

In the field of medicine, histopathology process is undertaken by pathologist.The aim of undertaking histopathology is to examine the existence or the possibility of a disease in the body tissue of a living thing. In addition, the process of histopathology is best practiced on the specimen of body tissue taken during the surgery of a patient. Here, the process involves a series of activities where surgery helps to remove body tissues for examination. After the surgery, the body tissue removed is placed in a fixative place where no external toxicities can contaminate the specimen. This forms the basis for ...

Frank Lloyd Wright’s Home and Studio remain the finest specimen of the architect’s innovative approach to the design of buildings in general and spaces for living in particular. The house is located in Oak Park, Illinois in a historic neighborhood which was later adorned by a number of other Wright’s houses representative of his unique style.

Impact Testing of Metals

Abstract Impact testing of metal experiment was conducted by performing Charpy V-notch impact tests and the ductile-brittle transition temperature of the three metallic samples was established. Three samples of metals were studied ( 1018 hot-rolled steel, brass and aluminum) to assess the Charpy V-notch impact energy as a function of temperature and the ductile-brittle transition temperature. The DBTT for the sample tested were recorded as follows: -109F, 32F, 71F, 140F and 205F respectively. From the results obtained, it is evident that the fracture energy varies with the original temperature of the specimen under investigation. For Steel, the highest fracture energy ...

Abstract

The eastern mosquitofish, Gambusia holbrooki, is a globally distributed species of viviparous freshwater fish, found in tropical and temperate climates. It is considered an invasive species on several continents, including Australia, and it may threaten the survival of certain critically endangered native species throughout the world. It is of great interest to ecosystem conservation to monitor and control their populations. To gain a better understanding of this non-native species’ life history with potential implications of other species, we used passive-capture methods to obtain a 365-specimen sample from a campus pond. The lengths of the specimens were used to estimate ...

Some parameters of urine “macroscopic” examination are quantity, color, clarity and cloudiness. Some of the constituents that might be observed in a urine “microscopic” examination are epithelial cells, crystals, bacteria or yeast and protozoan casts. Three conditions that can occur prior to a specimen being poured into a centrifuge tube that can produce false-negative microscopic results are the use of an old, unpreserved specimen, failure to mix the specimen and an amorphous precipitation. For the overall evaluation of the sediment and the detection and quantity of casts, the magnification that should be used is 100x. On the other hand ...

They can tell us a lot about the economic, political and religious circumstances of the specific region. They also narrate the contemporary architectural trend. In medieval Europe, especially in France, the Gothic architecture was at its pinnacle. Cathedral Notre-Dame de Chartres is one of the Gothic architecture examples in ...

Flu is a viral disease that influences for the most part the nose, throat, bronchi and, once in a while, lungs. Disease typically goes on for around a week, and is portrayed by sudden onset of high fever, hurting muscles, cerebral pain and extreme disquietude, non-beneficial hack, sore throat and rhinitis (WHO, 2016). The name "flu" started in fifteenth century Italy, from a plague ascribed to "impact of the stars." The principal pandemic, or overall pestilence, that unmistakably fits the portrayal of flu was in 1580. No less than four pandemics of flu happened in the nineteenth century, and ...

` The evolution of human beings is closely related to the evolution of the human brain. Brain capacity demonstrates how humans evolved from primitive to modern forms. By examining brain capacity across three different species of primates, namely Australopithecuas Africanus, Homo Habilis and Homo Erectus, it is possible to notice how brain capacity drastically increased, and with it, other modifications also took place, thus allowing modern humans (Homo Sapiens) to evolve into the present form. Based on primary research, this paper will examine brain capacity as a fundamental evolution characteristic, and will trace the transformations which took place from one ...

Introduction

Recently, worldwide obesity prevalence has been raised rapidly and nearly doubled between 1980 and 2014, however in 2014 more than a half a billion of adult (18 years and older) were obese (11% men and 15% women) (WHO, 2014). Obesity and overweight are defined as excess body fat accumulation that leads to health risks and comorbidities. Adult weight can be classified based on the Body Mass Index. Hence, an individual having a BMI equal to or more than 25 is regarded as being overweight, while a person with a BMI equal to or more than 30 is considered obese ( ...

Scanning electron microscope uses a beam of electrons to form images that reveal the topography and composition of a body. Before being focused on the object, incident electrons have high amounts of kinetic energy. Incident electrons interact with the surface of the specimen, and this interaction is determined by the rate of the acceleration of the incident electrons. Energetic electrons are usually released from the surface of the sample when the incident electrons come into contact with it. The interaction results in the formation of scatter patterns that interpret into the shape, composition, size, and texture of the specimen. ...

Introduction

Bend (flexure) testing is often done in springs as well in brittle materials whose behaviors of failure are linear like concrete, wood, plastic, glass and ceramics. Bend testing is suitable for evaluating the strength of brittle materials where the results of tensile tests aren’t easy to interpret due to the breaking of specimens around the gripping (Schoffstall, Charles, and Robert 234). In bend testing experiment, smooth rectangular specimens without notches are recommended under three or four point bend arrangements. Figure I below illustrates three point and four point bend arrangements respectively. Figure 1. Bend testing of a smooth ...

Introduction:

Transmission electron microscope (TEM) is the type of a microscope that uses a beam of electron rather than visible light to illuminate the specimen. Besides, while light microscope uses glass lens to focus light to the specimen, TEM uses electromagnetic lenses for focusing of the electron beam. TEM has a higher resolving power than the light microscope because the electron beam it uses for illumination has a much lower wavelength than visible light. During the operation of TEM, some electrons passing through the specimen get scattered and disappear from the beam. However, the unscattered electrons reach a fluorescence screen ...
