Soil samples collected from two major dumpsites each in Kano and Kaduna states were investigated for heavy metals pollution. Each of the dumpsite was divided into north, south, east and west. Four soil samples were collected at a depth of 0-15 cm from each part and pooled to form a composite sample. Soil samples from reserve areas within the same geographical locations as the dumpsites were collected as control. Acid-extractable cadmium (Cd), chromium (Cr), nickel (Ni) and lead (Pb) were...

Abstract Recent IPCC projections suggest that Africa will be subject to particularly severe changes in atmospheric conditions. How the vegetation of Africa and particularly the grassland–savanna–forest complex will respond to these changes has rarely been investigated. Most studies on global carbon cycles use vegetation models that do not adequately account for the complexity of the interactions that shape the distribution of tropical grasslands, savannas and forests. This casts doubt on...

The Internet is one of the latest technological breakthroughs in the history of Information and Communication Technology (ICT).Many government establishments, parastatals and private organizations use it for business transactions.Consequently, these organizations demand secretaries that are very knowledgeable and versatile in the use of Internet.Unfortunately, many secretaries do not possess Internet skills.The paper looks at the role of the Internet in office education programme and the...

Nigeria is the most populous country in Africa with an estimated population of over 140 million and a total land area of 923,773 km2. The country is currently losing about 351,000 ha annually to advancing desert and such conditions are estimated to be advancing southwards at the rate of about 0.6 km per year. The dunes are threatening life-supporting oasis, burying water points, and in some cases, engulfing major roads in the affected areas. Trees planted by the government as shelterbelts to...

ABSTRACT BACKGROUND: Correct and consistent condom use is an effective strategy to reduce the risk of sexually transmitted infections (STIs). This study examines sociodemographic, behavioral, and psychosocial characteristics of 3 groups of adolescent males: consistent, sporadic, and non‐condom users. METHODS: The sample consisted of 931 sexually experienced male high school students in Nairobi, Kenya. Cross tabulations and general linear models were used to test the relation between each...

A survey was conducted to determine the use of web-based information resources for medical research and education by the health professionals in University College Hospital, Ibadan.Questionnaires were administered to the health professionals in various departments in the Hospital.The results showed a low level of use in spite of high awareness level.This was due inter-alia, to lack of information technology skills, fluctuation of electricity, non-access to useful medical information internet...

During the last two decades state funding of higher education in South Africa has decreased substantially (especially if public expenditure of HE as a percentage of GDP is used as a yardstick). HE institutions were forced to increase tuition fees and rely more on the third income stream to balance their books. In the process increases in instruction/research staff did not keep up with the increase in student numbers. During the period 1986–2003 qualifications awarded to students per...
