BACKGROUND, AIM, AND SCOPE The blue swallow (Hirundo atrocaerulea) is one of the most threatened bird species in southern Africa. Among terrestrial birds, its plumage is known to be the most water repellent, an adaptation to foraging on the wing in dense fog. Despite this unique adaptation, the nesting success of the blue swallow at the Blue Swallow Natural Heritage Site (BSNHS) is lower during...

UNLABELLED Although widely used in air quality regulatory frameworks, the term "volatile organic compound" (VOC) is poorly defined. Numerous standardized tests are currently used in regulations to determine VOC content (and thus volatility), but in many cases the tests do not agree with each other, nor do they always accurately represent actual evaporation rates under ambient conditions. The pa...

INTRODUCTION Stemodia Benth. is a genus of about 40 species belonging to the family Scrophulariaceae occurring in tropical and subtropical regions of the world. The chemical investigation of this genus is restricted to five species from which flavonoids, labdane diterpenes, and diterpenes derivatives with a rare tetracyclic skeletal, named stemodane, were isolated. [1-3] The diterpenes of this ...

The investigation of deaths due to the inhalation of volatile substances may be complicated by a lack of scene and autopsy findings. Mechanisms of death may not be determinable at autopsy, and there may be very few markers of inhalant abuse. A 21-year-old man is reported who died from the combined effects of methadone toxicity and toluene inhalation. Histological examination of the lungs reveal...

The majority of workers are agreed that the digestion of carbohydrate in the rumen is brought about by the micro-organisms living there, and furthermore, that the microflora plays a much larger part in these processes than the microfauna, for if the Protozoa are removed by drenching with dilute copper sulphate, the digestive processes continued unhampered (see Van der Wath, 1942). The precise r...

in medicine, patent blue violet (pbv) is utilized for staining lymphatic vessels in sentinel lymph node (sln) surgery. moreover, pbv (also called e131 ) is used as food additive. we report on a 51-year-old non-atopic female with early breast cancer, who was scheduled for sln excision and experienced an intra-operative anaphylactic reaction. in diagnostics the skin prick test (spt) was positive ...
