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 ...

What is Ebola Where Ebola originated and the causes for it In this respect, J. Boulton states that Ebola was “up until now a little known tropical disease”. (Boulton, 2015) The purpose is to show why the Ebola has evolved from the unknown disease to an epidemic that swept all over Africa and threatened the rest of the world.

Studies conducted on Ebola and why they are important.

II. Introduction Ebola is a dangerous disease, also known as Ebola virus disease(EVD) or Ebola hemorrhagic fever. It is caused in humans by ebolaviruses. The main symptoms of the disease involve vomiting and diarrhea as well as ...

Introduction

Polymerase Chain Reaction (PCR) is a very influential technique that helps in amplifying the specific segments of DNA. This biochemical procedure is performed in-vitro that is quite different from cloning. This technique is a fusion of synthesis protocol of distinct repeated segments of DNA and thermostable DNA polymerase application that has given scientists a very potent analytical, immunological and molecular technique used prevalently in clinical laboratory science (Garibyan & Avashia, 2013). PCR is based on three primary steps that include denaturation of the template into single strands, annealing ...

Global warming is one of the biggest challenges the world is facing now. Also known as climate change, global warming is the gradual change in the average temperature of the planet’s atmosphere. This change in temperature is believed to be permanently changing not only the atmosphere’ temperature but also that of the world’s oceans. The increase in the carbon dioxide level and the depletion of the ozone layer is one of the primary reasons that have been accused of the increased climate change. The ozone layer is responsible for the protection of the earth from the dangerous ...

Introduction

Stainless steel is an important component in the modern industry having various uses in the industry. This has forced new developments in its manufacturing especially in terms of its composition. This can be the steel made from aluminum, manganese, and iron. All these materials makes the finished stainless steel product unique in terms of its composition, physical metallurgy, and other factors. This paper is going to discuss the development in stainless steel technology with regards to its composition in terms of the materials used. The materials that are going to be discusses are Al, Mn, and Fe. The paper ...

Abstract

Color and texture are important attributes related to vegetable quality. The objective of this study was to determine the changes in quality characteristics, caused by cooking time, and pH (alkali and acid addition) in some vegetables. Four different vegetables — carrots, spinach, red cabbage and cauliflower — were analyzed for changes in color and texture associated to time of boiling, the effect of alkali (baking soda), and the effect of acid (vinegar and cream of tartar). Samples of each vegetable were prepared and treated for five minutes. Color change was measured visually and using the L*a*b* technique. Color and ...

I. Introduction Advances in recombinant DNA technology and bioinformatics-based data analysis have driven the explosion of structural biology in the last two decades (Kelly, Jess, and Price 119). This has resulted to the identification of at least 2000 proteins annually and a growing need in performing structural studies in these new proteins. The current trend involves the concern of analyzing protein structures close to its natural conditions (and other conditions) and of measuring their rates of structural changes, an essential factor in their biological functions. The technique of circular dichroism (CD) has gained an increasing popularity in addressing these ...

A brake is a device that produces artificial resistance to the moving part of a machine to stop or slow down its motion. Any machine or its part that is in motion possesses kinetic energy. As per physical laws, energy cannot be destroyed; its form can only be transformed. The brake system converts the kinetic energy of the moving machine or part into thermal, potential or chemical energy. Brake systems are of various types utilized in different applications in industries, home appliances, vehicles, railway trains, and other sectors. This paper has focused on the brake systems used in vehicles, ...

Introduction

Stainless steel is an alloy with iron as major part and chromium with at least 11% by weight . Stainless steel industry grew rapidly during the 1989-93 period . This paper analyzes stress corrosion of stainless steel along with prevention measures and selection methods for stainless steel. After carrying out the study, it would be established whether stainless steel is an effective alloy or not for major uses in steel industry through adopting various selection parameters. Stainless steel is called stainless due to the resistance to rusting and corrosion .

Stress-corrosion in Stainless Steel

In order to reduce various occurrences of intergranular stress-corrosion cracking and severe ...

Introduction

All the actions and activities involved in managing the waste from its generation to its final disposal is called the waste management. It is the precise name given to the monitoring, collection, transportation and disposal of waste. Human activities are responsible for the production of so much waste every year, so, the management of waste is necessary to avoid its adverse effect on the environment and human health. Waste can also be managed to get resources from it. All kinds of waste like solid, liquid, gaseous and radioactive matter needs to be managed. Developed and Developing countries may have ...
