Polychaete worm tubes within the mid to lower intertidal zone along the South African west coast were frequently observed to be overgrown by a minutely papillate species of encrusting coralline algae. Analysis of the ...

Although water resources managers speak of a water crisis in Africa, the management of ground water has to date not featured strongly in national and regional African water agendas. Examination of the physical environment of ...

The encrusting coralline alga, Leptophytum foveatum, is the most abundant crustose alga in the lower eulittoral zone at Yzerfontein and other exposed sites on the West Coast of South Africa. The surface of this species is ...

Severe acute respiratory syndrome (SARS), a life-threatening disease, is caused by the newly identified virus SARS coronavirus (SARSCoV). In order to study the spike (S) protein of this highly contagious virus, we established ...

The p10 gene was identified and characterized from the Trichoplusia ni single capsid nuclear polyhedrosis virus (TniSNPV). The p10 open reading frame (ORF) sequence was identified following sequencing of the ends of the ...

RNA helicases of the DEAD (Asp-Glu-Ala-Asp)-box family of proteins are involved in many aspects of RNA metabolism from transcription to RNA decay, but most of them have also been shown to be multifunctional. The DEAD-box ...

The non-recombining nature of the Y-chromosome determines the non-independence of alleles between loci. The evolution of short tandem repeat (STR) loci in the Y-chromosome is the result of different factors such as ...

Most of the pulsations which have been observed in sdB stars have very low amplitudes. Detection of modes from photometric observations is usually performed by noting the most prominent peaks in a periodogram or, ...

We split the total matter fluid into a bound (halo) component and an unbound (free particles) fluid component that is accreted by the halos. We adopt a different framework that treats the structure formation problem as a ...
