In general, the objective of distillation control is to maintain the desired products quality. In this paper, the performances of different one point control strategies for an aromatic distillation column have been compared through dynamic simulation. These methods are: a) Composition control using measured composition directly. This method sufferes from large sampling delay of measuring de...
effect of dietary and animal factors on milk fatty acids composition of grazing dairy cows: a review
in pasture-based milk production systems, using available farm resources in order to reduce feeding costs, the composition and functional properties of dairy cows’ milk are of considerable importance to the dairy farmer, manufacturer and consumer. basically, there are three options for altering the composition and/or functional properties of milk: 1) cow nutrition and grazing management, 2) cow...
a comprehensive study on the chemical composition of rainwater was carried out in obuasi, a gold mining town in ghana. rainwater samples were analyzed for major ions (ca2+,mg2+, k+, na+, nh4+, cl-, no3- and so4 2-) and trace metals (fe, al, zn, pb, cr, and cd). the rainwater was typically acidic with a mean ph of 4.76±0.47, which ranged from 4.0 to 5.6. the low ph found in the water suggests t...
low seed yield is a limiting factor for cross breeding and hybrid seed production in cyclamen. this study was performed to investigate pollen germination and its relation to cross-pollination success and fruit set in this plant. in order to achieve a high level of pollen germination, the effect of different concentrations of chemical compounds were examined on in vitro pollen germination of cyc...
the oil extracted from three major canola cultivars (hyolla401, hyolla420 and rgs003) grown in golestan province was analyzed for physico-chemical properties, fatty acid composition, minerals content, and stability during 16 weeks of storage. according to the results, the highest iodine value and refractive index belonged to hyolla401. the highest saponification value was observed in hyolla420....
olive oil in general due to it monounsaturation, stability, nutritive value, consistency, taste andaroma might be considered as a valuable and luxury oil. annual importation of olive oil to iran frommediterranean countries is on a large scale although some olive oils are produced in iran particularly in the northand some plantation has been applied in different provinces particularly in fars. t...
this study was investigated the effects of dietary estradiol-17? (e2) on growth, body composition and blood indices in acipenser stellatus. fish (40.9 ? 1.1 g average initial weight; n = 60 per group) were fed with three different diets containing 0 (control), 25 and 50 mg kg-1 dietary estradiol contents to apparent satiation for seven months. the results suggested that growth rate were decreas...
