Criteria for citing poverty alleviating facilities in target communities in Nigeria: A case study of Yobe State
Madaki Musa Janga

The Federal Government of Nigeria have created programmes to alleviate poverty, but indices on electricity, water, education, housing and health have shown that little have been done in the country’s effort to develop rural areas. Most of the development projects were not evenly distributed and as such very few groups of people benefited from such projects. One of the most critical decisions of poverty alleviation programme is the identification of the intended beneficiaries of the...

Effects of food additives and preservatives on man- a review
Inetianbor, J. E., Yakubu, J. M. and Ezeonu, S. C.

Food additives are organic substances that are intentionally added to food in small quantities during production or processing to improve the organoleptic quality (colour, flavour, appearance, taste and texture) of the food. Food preservative is a class of food additive that help to prevent food spoilage by preventing the growth and proliferation of pathogenic microorganisms like Clostridium spp , Bacillus cereus and Staphylococcus aureus. This can be achieved by bringing down the pH of the...
