β -Lactoglobulin is capable of binding fat-soluble compounds including vitamin A palmitate and is suggested to specifically enhance intestinal uptake of retinol. In this study, bioavailability of a vitamin-A-retinyl palmitate complex in skim milk and in water-based liquids was investigated in vitamin-A-depleted rats. First, rats were fed a vitamin-A-free pellet diet for 6 wk and were thereafter...

Twenty five patients who were exposed to oil mists at their place of work were investigated for possible work related asthma. Serial peak expiratory flow recordings showed 13 to have definite work related asthma, seven equivocal work related asthma, and three asthma unrelated to work; two had normal recordings. Subjects with work related asthma often produced different patterns of peak flow res...

Recent examination and treatment of the Worcester Art Museum’s Reclining Nude, c. 1925, oil on canvas, by the Dutch-born Fauve artist Kees Van Dongen (1877-1968) indicate that the artist used unorthodox materials and techniques, including selective varnishing to adjust color saturation and surface sheen. Examination also revealed resinlike beads exuded from unvarnished passages of paint conside...

Studies were performed to compare the physical and chemical characteristics and the in vitro macrophage cytotoxicity of oil and coal fly ash. Sampling methodology was developed to collect size-fractionated particulate matter from the smokestack of either a coal-fired or an oil-fired power plant. Morphological studies demonstrated particle heterogeneity, although most coal fly ash particles appe...

Guinea pigs immunized with intact or disrupted armadillo-grown human Mycobacterium leprae administered in aqueous or oil vehicles were tested with various dilutions of M. leprae suspended in saline, water-soluble M. leprae extract, purified protein derivative, and a water-soluble extract of normal armadillo tissue. The results demonstrated the following. (i) Under no conditions was any skin tes...

BACKGROUND Extensive native Jatropha curcas L. (Jatropha) crop areas have been planted in Central America marginal lands since 2008 as a non-edible prospective feedstock alternative to high-value, edible palm oil. Jatropha biodiesel is currently exclusively produced in the region at commercial scale utilizing alkaline catalysts. Recently, a free, soluble Thermomyces lanuginosus (TL) 1,3 specifi...

Desalting/dehydration plants (DDP) are often installed in crude oil production units in order to remove water-soluble salts from an oil stream. This paper describes the development of simple inferential estimators for product quality of the desalting/dehydration process. The inferential estimators were constructed to capture the relationship between the product quality of the plant and the proc...
