Abstract Adolescents in South Africa are at particularly high risk for human immunodeficiency virus (HIV), as well as other sexually transmitted infections. Because rates are so high, using minimal time and resources to develop effective interventions is essential. One strategy to achieve this goal is to modify and adapt western school-based preventive interventions for application in South African schools. This study focuses on the adaptation and integration of two interventions with proven...

The Greater Olkaria Volcanic Complex is a young (≤ 20 ka) multi-centred lava and dome field dominated by the eruption of peralkaline rhyolites. Basaltic and trachytic magmas have been erupted peripherally to the complex and also form, with mugearites and benmoreites, an extensive suite of magmatic inclusions in the rhyolites. The eruptive rocks commonly represent mixed magmas and the magmatic inclusions are themselves two-, three- or four-component mixes. All rock types may carry xenocrysts...

Background: Hypertension has been reported among young people worldwide. It is known to track from youth to adulthood, which makes it a useful predictor of essential hypertension in adulthood. This study determined the prevalence of hypertension and associated cardiovascular risk factors among secondary school teenagers in Kano, Nigeria. Methods: A questionnaire was administered on a cross section of 1000 teenage students to inquire about cardiovascular risk factors. Participants\' blood...

Background: HIV/AIDS is a scourge that has seriously compromised the lives of millions of people, especially those living in sub-Saharan Africa. With continued high prevalence, there is a high risk of healthcare workers, especially those in the surgical specialties, acquiring the infection. This study was done to investigate the impact of HIV on the choice of surgical specialties in a training institution located in Jos, north-central Nigeria. We hypothesized that the awareness of the risk...

The study compared trans-arterial approach and mid-humeral technique of axillary brachial plexus block in terms of the clinical benefit of each method; adequacy of block, onset of sensory and motor block, duration of block and complications. .In a prospective randomized study, axillary plexus block was carried out in 50 patients undergoing surgery on the hand or forearm. Trans-arterial approach was used in 24 patients while 26 patients had a mid-humeral axillary plexus block. Equal volume,...

Abstract Despite numerous HIV and AIDS training programmes for educators, little appears to have been achieved in terms of creating a wider understanding of the social and cultural complexities of the disease and its impact on the quality of teaching and learning. There appears to be a lack of developmental programmes that help principals provide the type of leadership which ensures that teachers and children who live in a context affected by the disease still find themselves in a school...

The integration of indigenous knowledge/languages in formal education is a contentious issue in post-colonial Africa. For historical and economic reasons, these are devalued in the formal education system. We argue that appropriate use of indigenous knowledge/languages can empower African students academically even in typically “Western” disciplines, such as Computer Science. We discuss the potential role of indigenous languages/knowledge in ICT education and then describe an intervention,...

Information and Communication Technologies (ICTs) are increasingly considered valuable tools in education, promoting the development of higher cognitive processes and allowing teachers and learners access to a plethora of information. This paper reports on two pilot studies conducted in South Africa in proto-typical previously disadvantaged schools and their surrounding communities. Each pilot study deployed a local loop network within impoverished communities, connecting schools to one...

This paper illustrates how interactive whiteboards (IWBs) have been used to support the dynamic creation, capture and sharing of knowledge in primary and secondary schools in South Africa. It reports on the findings of a feasibility study undertaken by the Eastern Cape Department of Education to determine the perceived benefits and drawbacks of teachers and learners of using IWBs in the classroom. The research highlights how both teachers and learners can critically engage with multiple...

Abstract. In 1856, one (or two) destructive earthquake(s) occurred off Djijelli (Algeria) and probably triggered a tsunami in the western Mediterranean Sea. Following recently published results of marine campaigns along the North-Algerian margin, a new source hypothesis for the earthquake has been proposed, and is constituted with a set of three "en échelon" fault segments positioned in agreement with previous studies of this earthquake and with macroseismic data available. The geometrical...
