natural gas is often associated with nitrogen and heavy compounds. the heavy components in the natural gas not only can feed downstream units, owing to the low temperature process may be formed solid as well. therefore, heavy components separation can be a necessity and produce useful products. virtually, all natural gases are containing nitrogen that would lower the heating value of natural ...
achieving a desirable percutaneous absorption of drug molecule is a major concern in formulating dermatological products. the use of penetration enhancers could provide a successful mean for this purpose. the aim of this study was to evaluate the effect of incorporating a few common penetration enhancers (in different concentrations) into a 0.5% w/w piroxicam (model drug) gel formulation, on th...
The water-soluble vitamins vary widely in chemical structure and properties, so it is not surprising that the characteristics of absorption of individual members of the group also show differences. Water-soluble vitamins are absorbed mainly into the blood, some very freely (e.g. ascorbic acid), others (e.g. thiamine) only in limited amounts. Vitamin Biz has an apparently unique mode of absorpti...
Octodon degus is a desert rodent of northern Chile, adapted to survive with a limited supply of water. This rodent has a high degree of fecal dehydration, related to colon water absorption. With the hypothesis that aquaporins (AQPs) might be present in the colon epithelium of O. degus and involved in fluid absorption, we studied colon water absorption in vivo and the distribution of AQPs and Na...
The relative impermeability of the surfaces of leaves to water and mineral ions in solution is a condition upon which the life of terrestrial higher plants depends. However, for the investigator this feature imposes difficulties on attempts to make quantitative studies of the process of ion absorption by leaf tissue. The importance of this absorption process in the physiology of leaf cells has ...
When euryhaline teleosts are adapted to waters of salinities higher than the osmolality of plasma an increase in drinking rate has been observed (Lotan, 1969; Maetz, 1970; Maetz & Skadhauge, 1968; Potts et al. 1967; Shehadeh & Gordon, 1969). This is to be expected since drinking, and absorption of salt (NaCl) and water through the intestinal wall, is the only way for the fish to get water to ma...
dry beans are rich sources of dietary fiber and phytochemicals such as flavonoids and phenolics that exhibit good functional properties. in current study line, cooking and soaking time effects were investigated on water absorption, splitting and texture properties of different iranian red kidney beans to determine the best lines and the best soaking time for industrial use. d81083 line showed t...
To investigate the possibility of using bamboo-bundle laminated veneer lumber (BLVL) as a cooling tower packing material, the water absorption rates, thickness swelling rates, and flexural properties of three different composite materials were studied. The BLVL was combined with either 12% or 24% phenol formaldehyde resin (PF), and the moso bamboo strips were exposed to water baths at three dif...
