Introduction

Accurate temperature measurement is a very vital and common requirement in every industrial instrumentation process. It is however very difficult to achieve this objective. Unless the techniques used to measure temperature are proper and effective, massive reading inaccuracies can occur leading to the accumulation of useless data. This is where the thermocouple comes into play. This device is a temperature sensor that is widely used in all corners of the globe. It has very many favorable characteristics and these include: high inherent accuracy; wide temperature range suitability; high reliability; great application versatility, fast thermal response and relatively low cost. The thermocouple ...

A condition affecting the system of veins in legs with venous hypertension resulting in different pathologies that involve swelling, ulcerations, pain, skin changes, and edema is called chronic venous insufficiency (Eberhardt and Raffetto, 2005).
It is necessary to understand normal venous function and anatomy to analyze the venous insufficiencies pathology. The peripheral venous system serves as a conduit returns blood into the heart and as a reservoir where blood is stored. Appropriate operation of the peripheral venous system is dependent on a series of muscle pumps and valves (Eberhardt and Raffetto, 2005). Blood entering the venous system of lower extremities has ...

Iran’s nuclear program is one of the most controversial issues that concern many nations, especially its neighboring Arab countries, Turkey, and Israel. Iran agreed to repudiate its ownership of weapons of mass destruction that includes chemical and biological weapons through various treaties. Iran has also ratified the NPT or the Nuclear Non-Proliferation Treaty (Federation of American Scientist), which made Iran’s nuclear program a subject to IAEA’s verification. Iran’s nuclear program was initially cancelled right after the revolution in 1979, but it was revived during the latter part of war with Iraq in 1988. It has ...

- Linear and Non-linear devices
A linear electrical component is an electrical element that has a linear relationship between current and voltage in a circuit. Examples include resistors, capacitors and inductors.
Non-linear electrical elements do not have a linear relationship between the current and voltage. An example is a diode where the current is a non-linear function of the voltage.
The load line analysis is a graphical analysis of the characteristics of non-linear electronic circuits to show the constraints that is placed on the non-linear devices by the rest of the circuit.
Using a simple diode (a non-linear electronic device) to explain the ...

Abstract

Gastroesophageal reflux disease (GERD) is due to weakening of the lower esophageal sphincter tone and is thought to be one of the most common disorders of the gastrointestinal system (Harrison’s, 2008). The loss of tone in the lower esophageal sphincter (LES) allows gastric contents to flow backwards into the esophagus (Kahrilas, 2013), causing damage to the normal esophageal mucosa. Simple measures, such as lifestyle changes can be employed to try and live with the condition, but usually the treatment is medical with various drugs to make the pH of the gastric acid less acidic as to lessen the ...

Abstract—In this experiment, a hand dynamometer was used to measure the grip strength of a subject. The forearm muscles were engaged in an activity, and the grip recorded. The electromyogram (EMG) activity was related to the grip strength by making a graph of the maximum grip strength against area under the EMG activity’s absolute integral during the contraction of muscle. Data was recorded from the dominant and non-dominant forearms of the subject and the electrical activity of each forearm compared to its diameter. Prolonged grip strength was also recordings and forearm EMG activity made to determine fatigue rate in both ...

Abstract

This paper adequately and sufficiently dwells into the concept and usage of cooling systems in computers. It talks about the advents which have been made in the cooling technology right from the very starting to the modern times. It discusses and elaborates on the different kinds and types of cooling systems available and their respective advantages and potential, if any, disadvantages.

Cooling Systems in Computers

According to Moore’s Law the number of transistors on a chip will double approximately every two years. Since 1965 this law has stood the test of the times and consequently the performances of computers have increased while their ...

Definition and history of stomach cancer

Stomach cancer also called gastric cancer is a disease that is characterized by the uninhibited proliferation of abnormal cells in the tissues lining the stomach. These cells are abnormal in the sense that genetic mutations render them autonomous hence they are not under the control of growth regulating signals. Gastric cancer used to be the second most prevalent cancer but sharp declines have been seen in its rate in the developed countries especially over the second half of the last century, for instance it is the fourteenth most common malignancy in the United States. However, the same cannot be said ...
