background: reservation of blood leads to blood wastage if the blood is not transfused. therefore, in some centers only blood type and screen are evaluated. in this study, the efficacy of a blood crossmatch-to-transfusion ratio was measured and then compared with the standard levels. methods: this prospective study was conducted during one year in a university hospital. during this period, 398 ...

background: aflatoxin m1 (afm1) is a toxic compound that could be found in milk and dairy products. afm1 is the principle hydroxylated derivative of aflatoxin b1 (afb1), formed in liver and excreted into the milk in the mammary glands of both human and lactating animals that have been fed with afb1 contaminated diet. to the best of our knowledge, there is no report on stability of afm1 during p...

background: antioxidant activities of plant extracts are being studied to increase the shelf life of fish products. some plants such as urtica dioica l. (nettle) can be a good source of antioxidants. the objective of this study was to evaluate the effects of hydroalcoholic and water extracts of nettle leaf on the chemical properties of superchilled minced meat of the common kilka fish (clupeone...

water use productivity is one of the most important factors in scientific agriculture. it is equal to 0. 7 kg of production per cubic meter of irrigation water (kg/m3) in iran which is very low in comparison with advanced countries (1 to 2 kg/m3). current research studies temporal and spatialchanges of water use productivity in hamedan province in iran using geographic information system (gis),...

S OF PAPERS 205 The tool was designed using International Panel on Climate Change (IPCC) emission factors and equations and estimates GHG emissions that occur within the boundaries of the poultry farm that are under the control of the poultry producer. The carbon footprint estimation tool converts farm inputs into carbon footprint equivalents (CO2e). These farm inputs include energy bills such ...

We show that there exist two proper creature forcings having a simple (Borel) definition, whose product is not proper. We also give a new condition ensuring properness of some forcings with norms.

To address technology impact at the household level, farms were selected in two broad agro-ecological zones, Kampala and Highland. The Kampala zone was delineated as a “new” region with a substantial milkshed that was not delineated with the Kenya agro-ecological extrapolation. Since the “Horticultural” zone and Kenya dominated the landscape where dairying occurred outside of the Kampala milksh...

Natural products account for a significant proportion of modern day therapeutic agents. However, the discovery of novel compounds is hindered by the isolation process, which often relies upon extraction and chromatographic separation techniques. These methods, which are dependent upon the physicochemical properties of the compounds, have a limited ability to both purify and concentrate the mino...

The convergent total synthesis of the marine natural product (+)-bistramide C confirms the a priori assignments of its relative and absolute configurations, which were originally based on the combined application of [alpha]D analysis, NMR, and synthesis.
