Coastal and marine tourism is a sector that draws visitors from around the globe to South Africa.This is largely because of an array of marine wildlife resources found in the country.Despite this strong pull factor, there is limited information on the economic value of the marine environment.This article focuses on establishing the profiles of visi
Despite the fact that animal posture is known to reflect emotional state, the presence of chronic postures associated with poor welfare has not been investigated with an objective tool for measuring, quantifying and comparing postures.The Activities use of morphometric geometrics (GM) to describe horse posture (profile of the dorsum) has shown to b
Summary: Thyroid nodules are a common disease, and fine needle aspiration cytology (FNAC) is the primary method to assess their malignancy.For the diagnosis of follicular thyroid nodules, however, FNAC has limitations.FNAC can classify them only as Bethesda IV nodules, leaving Parts their exact malignant status and pathological type undetermined.Th
Pulmonary arterial flow was examined in 60 normal children with a mean age of 8.5 +/- 3.7 years (range 3.3 to 17.9 years) and mean body surface area of 0.95 +/- 0.3 m2 (range 0.6 m2 to 1.7 m2) by pulsed Doppler echocardiography.Two distinct antegrade waveforms during diastole were detected.The peak velocities of early diastolic forward flow ranged
A novel facile technique is proposed for fabricating three-dimensional (3D) concave nanolens arrays on a silicon substrate.The technique leverages an inherent characteristic of the polymethyl methacrylate (PMMA) resist during inductively coupled plasma (ICP) etching.The tendency for plasma ions to accumulate at the edge of the PMMA resist helps cre
