rheological properties of chocolate are important in manufacturing process for obtaining high-quality products with well-defined texture and are directly influenced by composition and their refining time. soy protein benefits from nutritional and functional properties to be used in different foods. effects of different replacement levels of skim milk powder by soy flour, (from 0 to 100%) and ba...

We performed a quantitative trait locus (QTL) analysis of epicuticular hydrocarbon variation in 1650 F(2) males from crosses of Baja California and mainland Mexico populations of Drosophila mojavensis cultured on two major host cacti. Principal component (PC) analysis revealed five PCs that accounted for 82% of the total epicuticular hydrocarbon variation. Courtship trials with mainland females...

The profiles of major volatile organic compound (VOC) sources in petrochemical industry of the Yangtze river delta, China, were experimentally determined. Source samples were taken using summa canister near the petrochemical units. The concentrations of 72 VOC species were quantified using canister sampling and a gas chromatography–mass spectrometry system, and VOC source profiles were develope...

due to the location of a domestic, industrial and agricultural zone near the caspian sea, this water body has long been under pressure and environmental threat. as a result of development of oil production activities in caspian region, such as oil exploration and extraction, a large volume of oil related pollutants is released annually into this important water body. considering the fact that h...

Hydrocarbon aspiration causes acute lung injury, which may lead to acute respiratory distress syndrome. Surfactant has been shown to be beneficial in experimentally-induced hydrocarbon-associated acute respiratory distress syndrome. However, there has not been a clinical study evaluating the effect of surfactant application on hydrocarbon aspiration in humans. We report a 17-month-old boy with ...

The formation of chromophores and leucochromophores during the manufacturing of thermomechanical pulp (TMP) has been investigated. As analytical tools, advanced UV-VIS and NMR spectroscopy have been used. With the exception of some pilot plant scale refining experiments, that were carried out at Valmet Fibertech (Sundsvall), the work has been conducted at the Royal Institute of Technology (Stoc...

Technological Change, Depletion and the U.S. Petroleum Industry*** A common claim in the nonrenewable resource literature is that improvements in technology may largely offset the effects of increasing scarcity over time. This study provides perhaps the first empirical evidence on this issue by analyzing the determinants of the average finding cost for additional petroleum in the U.S. over the ...

BACKGROUND Heightened awareness of the health benefits of fish oil consumption has led to a great increase in the number of fish oil supplements available to the consumer. Therefore manufacturers are continually looking for ways to distinguish their products from those of competitors. Minimally refined or virgin fish oils provide a unique feature; however, petroleum hydrocarbon contamination fr...
