CORROSION BEHAVIOUR OF METALS/ALLOYS WITH AND WITHOUT COATING AT HIGH TEMPERATURE (200 – 1000OC) AND UNDER MARINE ENVIRONMENT

INTRODUCTIONCorrosion is the deterioration a material undergoes as a result of its interaction with its surroundings. Although this definition is applicable to any type of material, it is usually reserved for metallic alloys. Of the 105 known chemical elements, approximately eighty are metals , and about half of these can be alloyed with other metals, giving rise to more than 40,000 different alloys. Each of the alloys will have different physical, chemical, and mechanical properties, but all...

Reduction of the effect of cell phone electromagnetic radiation on human body

ABSTRACT This project work was carried out to access the level of electromagnetic radiation risk awareness from cell phones in selected audience of cell phone users using a Questionnaire. The reduction in the adverse effect of electromagnetic radiation from cell phones is theoretically explained in the research work. The Questionnaires were distributed at seven (7) different diagnostic centres working with radiations and also cell phone users. The level of awareness of the workers was found t...

Roles of bacteriocins in food safety

INTRODUCTION DEFINITION AND HISTORY Bacteriocins are bacterial ribosomally synthesized peptides or proteins with antimicrobial activity. As ribosomally synthesised peptides, bacteriocins are encoded by a plasmid- or chromosome-borne structural gene which is often clustered with genes coding for immunity protein(s) and dedicated transport. Bacteriocins are proteinaceous toxins produced as a tiny molecule by bacteria to inhibit the growth of similar or closely related bacterial strain(s) produc...

DESIGN AND IMPLEMENTATION OF AUTOMATED MOTOR VEHICLE DRIVING SYSTEM

Mycotoxins: Characterization , Occurrence and Detection

INTRODUCTION Mycotoxins are pharmacologically active mold metabolites produced in a strain-specific way that elicit some complicated toxicological activities (Bennett, 2003). Mycotoxins could also be described as secondary metabolites produced by a wide variety of organisms categorized as fungi, including mushrooms, yeasts and molds. The term mycotoxin was used for the first time in 1961 in the aftermath of a veterinary crisis in England, during which thousands of animals died. The disease wa...

THE EFFECT OF ENVIRONMENT ON CORROSION

ABSTRACT In this research project, the various nail was subjected to six environments so as to check the effect of the environments on corrosion of the nails. Two sets of nails were used; normal nail and concrete nail.  Six of each type while the other not coated. The environments used are acidic solution, alkaline solution, salt solution, boiled water, air medium and lubricating oil medium, which served as a control medium. It was observed from the graphs of the weight of metal against time...

ISOLATION, IDENTIFICATION AND CLASSIFICATION OF FUNGI

INTRODUCTION  A fungus is any member of a large group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, Fungi, which are separate from plants, animals, protists, and bacteria. One major difference is that fungal cells have cell walls that contain chitin, unlike the cell walls of plants and some protists, which contain cellulose, and unlike the cell walls of bacteria. These and ot...
