Abstract: Research on the isolation and characterization of bacteria degrading polystyrene-starch polymer coatings of slow release urea fertilizer was carried out to see the efficiency of decomposition of slow release urea fertilizer coating polymers assisted by bacterial microorganisms. The research was conducted using a field survey method and followed by an experimental method. The stages of the research were carried out starting from taking soil samples in the plant root area and isolating bacteria using certain media to obtain bacteria that have the potential to degrade......

Abstract: The term biofuels usually apply to liquid fuels and blending components produced from biomass materials called feedstocks. The alarming rate of consumption of fuels is a major economic issue in the context of increasing energy demand all over the world. It has become increasingly obvious that continued reliance on fossil fuel energy resources is unsustainable, owing to both depleting world reserves and the greenhouse gas emissions associated with their use. Therefore, there are vigorous research initiatives aimed at developing alternative renewable and potentially......

Abstract: Background: Fish grilling by using charcoal emits toxic gaseous substances that can have short-term or long-term effects on human systems. Other studies separately on Biochemical and haematological parameters reported that exposure to some air pollutants during fish grilling can be injurious to humans. This study investigated the effect of smoke residues on fish grillers in mammy market of Mogadishu cantonment, Abuja, Nigeria.
Material and methods: The subject of this study were 95 that composed of 75 fish grillers as test groups and 20 non-fish grillers but doing other occupations within the market as control groups. Demographic data were obtained from them using a structured questionaire.......
