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

ABSTRACTThis 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 to...

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...

Polymer Degradation

ABSTRACTPolymers are used in various ways and they constitute the bulk of demand in the utilization of basic petrochemicals both in industries and domestic uses. Polymers have posed serious environmental problems because of their undegradability. Polymer degradation is a change in the properties of a polymer or polymer based products under the influence of one or more environmental factors such as heat, light, chemicals such as acids, alkalis and some salts, atmospheric oxygen, microorganisms...

ANTIBACTERIAL ACTIVITY OF HONEY ON (STAPHYLOCOCCUS AUREUSESCHERICHIA COLI AND STREPTOCOCCUS PYOGEN) ISOLATED FROM WOUND

ABSTRACTAntibacterial activity of honey obtained from two different locations in Enugu State (Nsukka & Ugwuaji) Nigeria on Staphylococcus aureus, Escherichia coli and Streptococcus pyogens isolated from wound was studied. Agar well diffusion method was used to determine the antibacterial activity of the honey on the test microorganisms. The result revealed that the two honey samples have heavy antibacterial activities against the test organisms and zones of inhibition were obtained showin...

THE EFFECTS OF ESTERIFICATION ON COLD WATER SOLUBILITY OF CASSAVA STARCH

ABSTRACTThe aim of this study is to improve the Cold Water Solubility (CWS) and esterification activity of Native cassava Starch (NS) by pretreatment using NaOH (Sodium hydroxide) aqueous solution. The influence of pretreatment on granule shape and crystal structure of cassava starch was investigated by Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD). It has been found that the average particle size of Pretreatment cassava Starch (PS) decreased to nanometer level, smaller than ...

Mechanisms of action of some probiotics

INTRODUCTIONThe term probiotic (opposite of antibiotics) is used when we refer to bacteria associated with beneficial effects on humans and animals. It was invented in the early twentieth century by Nobel Prize winner, Eli Metchnikoff, and introduced in his study, the prolongation of Life. (Metchnikoff, 1907).Metchnikoff has shown since 1907 that Lactobacillus bulgaricus is able to eliminate pathogenic bacteria from the intestinal microflora. The actual introduction of the concept belongs to ...
