OBJECTIVE The study determined the impact of a community-based nutrition education programme, using trained community nutrition advisors, on the anthropometric nutritional status of mixed-race children aged between 2 and 5 years. DESIGN AND SETTING The programme was implemented over two years in four study areas in the Free State and Northern Cape Provinces. Two control areas were included to...

The susceptibility of the larval offspring of engorged female Boophilus decoloratus, and of the engorged females, collected from cattle on the dairy farms Brycedale, Sunny Grove and Welgevind in the Eastern Cape Province, South Africa, was tested against the acaricides amitraz, chlorfenvinphos and cypermethrin. Resistance was determined by means of the Shaw Larval Immersion Test (SLIT) for larv...

Last November, a month after his 32nd birthday, Rene Gonzalez moved with his wife and two young daughters from Miami to Cape Coral, a wetlands community whose canals have earned it the nickname the Little Venice of Florida. In Miami the competition in his chosen career—nutritional supplement sales—was fierce, and Cape Coral offered a less congested marketplace. He opened a small store, Just Add...

We examine the definition S = lnΩ as a candidate function for “gravitational entropy.” We calculate its behavior for gravitational and density perturbations in closed, open and flat cosmological models and find that in all cases it increases monotonically. We are also able to calculate the entropy density of gravitational radiation produced by inflation. We compare the results with the behavior...

OBJECTIVES: To assess and quantify the magnitude of inequalities in under-five child malnutrition, particularly those ascribable to socio-economic status and to consider the policy implications of these findings. METHODS: Data on 3765 under-five children were derived from the Living Standards and Development Survey. Household income, proxied by per capita household expenditure, was used as the ...

The objective of this study was to determine the species composition of ixodid ticks infesting domestic dogs in the northwestern region of the Northern Cape Province of South Africa and in Namibia. Ticks were collected from February 2008 to January 2009 from dogs presented for a variety of reasons at a veterinary clinic in the Northern Cape Province and at 3 clinics in Namibia. The ticks collec...

The spatial and temporal patterns of plant species radiations are largely unknown. I used a nonlinear regression to estimate speciation and extinction rates from all relevant dated clades. Both are surprisingly high. A high species richness can be the result of either little extinction, thus preserving the diversity that dates from older radiations (a 'mature radiation'), or a 'recent and rapid...

Innovative experimental field designs and methods are instrumental for dissecting hydrological processes in hillslopes. However, experimental studies at the catchment scale are rarely affordable to most research groups, and laboratory flumes are oversimplified to reproduce natural phenomena. In this work, we present the innovative “hybrid” experimental plot of Cape Fear, which features controll...

BACKGROUND Major incidents put pressure on any health system. There are currently no studies describing the epidemiology of major incidents in South Africa (SA). The lack of data makes planning for major incidents and exercising of major incident plans difficult. OBJECTIVE To describe the epidemiology of major incidents in the Western Cape Province, SA. METHODS A retrospective analysis of t...

Agricultural parastatals were a common feature during apartheid and were intended, according to the government, to address poverty in the Bantustans. However the failure of these projects to achieve the publicised goals, mainly due to their heavy dependence on government funding, led to a belief that their establishment was motivated more by politics than the stated reasons. Following a review ...
