PURPOSE OF REVIEW Systemic vasculitides are characterized by inflammation of blood vessel walls leading to a myriad of organ disorders depending on the size, site, and location of the affected blood vessel. The epidemiology of vasculitis in the developing world has been inadequately documented. The description of the vasculitides in Africa, both from hospital series as well as taking into consi...

Established illiquidity measures are constructed for emerging markets in Africa and used to determine which best explain trading costs. Costs of equity are derived from an augmented CAPM for a sample of emerging financial markets generally ignored in the literature. These include: South Africa and Namibia, three countries in North Africa and four in SSA, plus London and Paris as examples of int...

Aerosols are among the most important of atmospheric pollutants observed like the microscopic particulate matter in the lower parts of the troposphere. The main purpose of this study is introducing a new method based on satellite images processing results and nonlinear analysis (fractal based) to investigate the origin and dynamical mechanism of aerosols distribution in North Africa and the Mid...

Multiple sclerosis is rare among the indigenous black people of Africa. The first account of a black patient with multiple sclerosis in South Africa was published as late as 1987. Since then a search to find black patients with multiple sclerosis in Southern Africa has continued. Seven black patients have now been traced in South Africa and five in Zimbabwe in whom a diagnosis of multiple scler...

The first appearance of explicitly symbolic objects in the archaeological record marks a fundamental stage in the emergence of modern social behavior in Homo. Ornaments such as shell beads represent some of the earliest objects of this kind. We report on examples of perforated Nassarius gibbosulus shell beads from Grotte des Pigeons (Taforalt, Morocco), North Africa. These marine shells come fr...

Astronomically forced insolation changes have driven monsoon dynamics and recurrent humid episodes in North Africa, resulting in green Sahara Periods (GSPs) with savannah expansion throughout most of the desert. Despite their potential for expanding the area of prime hominin habitats and favouring out-of-Africa dispersals, GSPs have not been incorporated into the narrative of hominin evolution ...

This study considers the role of distance to the African source on the amount of deposition. To this end, dry and wet deposition was measured at a site close to Africa (Santa Cruz de Tenerife in the Canary Islands, SCO) and at a distant site located in NE Spain (La Castanya, Montseny, MSY). Because of the important influence of African influence on the buildup of particles in the atmosphere, we...

Maternal mortality is an important measure of women's health and indicative of the performance of health care systems. Several international conferences, most recently the Millennium Summit in 2000, have included the goal of reducing maternal mortality. However, monitoring progress towards the goal has proved to be problematic because maternal mortality is difficult to measure, especially in de...
