The relationship between CO(2) concentration and starch synthesis and degradation was studied by measuring leaf starch content and disappearance of (14)C-starch. At a concentration of 340 microliters CO(2) per liter, starch accumulated without degradation of previously synthesized starch. Degradation of starch began when CO(2) concentration was lowered, but its synthesis continued. At 120 micro...
BACKGROUND The proportion of starch disappearing from the small intestinal lumen is generally lower in ruminants than in monogastric animals, and there are indications that the starch digestion capacity in ruminants is limited. OBJECTIVES Milk-fed calves were used to study the rate-limiting enzyme in starch hydrolysis and to quantify starch fermentation in ruminants. METHODS Forty male Hols...
in this study, the usage of starch as adhesives in packaging industry and improving the properties of starch on the development of its applications have been discussed. starch is widely used in various industries, but in the celluloses packaging industry it can be just used as a coating binder, sizing agent or adhesive industries. in these industries, high print quality, low water absorption an...
The effects of heat treatment on oat and barley starch water dispersions were investigated. As compared with barley starch, the granules from oat starch were more degraded, but the fractionation patterns of both starches were not significantly different. Microscopic examination indicated that no evidence of amylopectin fragments was observed in the liquid fraction after starch dispersions were ...
BACKGROUND Foam sclerotherapy (foam) and endovenous laser ablation (EVLA) have emerged as alternative treatments to surgery for patients with varicose veins, but uncertainty exists regarding their effectiveness in the medium to longer term. OBJECTIVES To assess the clinical effectiveness and cost-effectiveness of foam, EVLA and surgery for the treatment of varicose veins. DESIGN A parallel-...
Due to a surge in demand and cost, there is requirement for alternative energy sources by devising strategies the efficient production of biofuels. Immobilized microbial systems conversion biomass fuels have become progressively important. Cassava (Manihot esculentum) processing waste, massive byproduct starch utilized this work bioethanol production. This study was an attempt design develop ex...
Introduction: Various iodine isotopes are undergoing radioactive decay except Iodine-127 (I-127. Iodine I-131 is unsealed radioactive material used in nuclear medicine for both diagnostic and therapeutic procedures in Royal Hospital since 2006. In radiotoxic classification, I-131 is in group 2 element. I-131 is highly reactive element due to its volatilization nature. Currently...
Fractured carbonate reservoirs account for 25% of world’s total oil resources and for 90% of Iranian oil reserves. Since calcite and dolomite minerals are oil wet, gas oil gravity drainage (GOGD) is known as the most influencing production mechanism. The most important issue within gas injection into fractured media is the channeling problem which makes the efficiency of gas injection process e...
Flexible Polyurethane (PU) foam samples with different densities and chemical formulations were tested in quasi-static stress-strain compression tests. The compression tests were performed using the Lloyd LR5K Plus instrument at fixed compression strain rate of 0.033 s-1 and samples were compressed up to 70% compression strains. All foam samples were tested in the foam rise direction and their ...
