Ground, decorticated bambara groundnut (BG) was incorporated as a non-conventional feedstuff at 0, 10, 20, 30, 40, and 50% levels; and fed to Nile tilapia fingerlings in glass aquaria at 5.0% of their body weight daily. All feeds contained 30% crude protein (CP). At all inclusion levels growth and feed conversion ratios improved
significantly (ANOVA: P< 0.05) over control.

It is now widely recognized that ownership and control over assets such as land and housing provide economic security, incentives for taking economic risks that lead to growth and important economic returns including income. Yet, women in many counties are far less likely than men to enjoy ownership or control of these important assets. Ensuring female property and inheritance rights would help to empower women and rectify a fundamental injustice [1].

Several studies have indicated the existence of thrombo-embolic complications in cancer patients and that this could be associated with changes in haemorheological parameters. Packed cell volume (PCV), haemoglobin (Hb), relative plasma viscosity (RPV) and plasma fibrinogen concentration (PFC) were measured in 50 healthy control women, 50 age-matched women with breast cancer, and 10 women with histopathologically proven benign breast tumour.

Because defects in the phenylalanine hydroxylase gene (PAH) cause phenylketonuria (PKU), PAH was studied for normal polymorphisms and linkage disequilibrium soon after the gene was cloned. Studies in the 1980s concentrated on European populations in which PKU was common and showed that haplotype-frequency variation exists between some regions of the world. In European populations, linkage disequilibrium generally was found not to exist between

The prevalence of HIV in Nigeria has been on a steady rise within the past decade. By the end of 1999, 2.7 million Nigerians were living with HIV/AIDS, translating into 400,000 new cases since the end of 1997. Despite glaring
statistics and evidence of HIV/AIDS as a major health crisis, there is a general under reaction, self-denial and subdued population response to the disease.

A close examination of Nigeria education literature reveals a general lack of interest in the conceptual analysis of the sociological basis of educational organizations. Consequently, this paper presents a modest attempt at providing a conceptual analysis of the sociology of Vocational and Technical (VOTEC) Institutions using Nigeria as a reference point, though its application to general education can easily be discerned.

Accounting information aids decision-making in the process of making a choice between or among alternative courses of action. The roles of accounting in this process cannot be underestimated. These can be substantiated by the reactions of investors to the financial statements of Organizations. Our reaction to an organization whose financial statement shows that it has been doing very well for the past five years or so is that we could invest in it if such an
organization goes into the Capital Market...

The family is regarded as the most basic unit of socialization and the socialization of children is highly dependent on it. The role of the father and mother in bringing up children are complementary. However, one of the parents is usually not present in the single parent family. Life in single parent family can be extremely stressful, in both economic and emotional terms.

Health is very important as it determines one’s productivity, earning capacity, educational performance, and it is fundamental to people’s ability to enjoy and appreciate other aspects of life. Unfortunately, many women world-wide and in Nigeria do not enjoy robust health. Three areas particularly affect women’s health and these have been identified as reproductive health/maternal mortality, early marriage and female genital mutilation. They threaten women’s health and therefore their productivity.

Science and Technology (S&T) is imperative to sustainable development that all sectors of the society have a role to play in developing the elements of sustainability. Research reports have shown that men have favourable attitudes toward science than women hence these females are under-represented in S & T fields. This paper addresses the issues of attitude of girls towards S & T, factors contributing to the unfavourable attitude of girls toward S & T and strategies of improving the attitudes.

Fish have been identified to be of great importance in Nigeria in meeting the animal protein need. The supply is in short of the demand due to some of the problems associated with the main source of supply (i.e capture fisheries with the natural water bodies already over fished and polluted). Emphasis is lately being shifted from the
capture to culture fisheries (i.e Aquaculture).
