life cycle assessment (lca) had proven to be an appropriate assessment tool for analysis of agri-food products by identifying, quantifying and evaluating the resources consumed and emissions released into the environment. this study was performed for evaluation the environmental impacts of potato agroecosystems based on nitrogen levels by using lca methodology. tuber yield mean during 1999-2013...

Materials and methods: One hundred eighty 21-day-old Yorkshire-Landrace pigs were randomly assigned to five treatments. Treatments were the unsupplemented, unmedicated basal diet (Control) and the basal diet supplemented with either 4.41 g per tonne flavomycin (Huvepharma, Inc, Peachtree City, Georgia; Flavomycin), 1.5 kg per tonne oregano oil (Van Beek Scientific, Orange City, Iowa; Oregano), ...

Materials and methods: In Experiment One, 180 seventeen-day-old YorkshireLandrace pigs were randomly assigned to three dietary treatments, including an unsupplemented, unmedicated basal diet (Control) and the basal diet supplemented with either 55 g per tonne carbadox (Phibro Animal Health, Ridgefield Park, New Jersey) or 1.5 kg per tonne oregano oil (Van Beek Scientific, Orange City, Iowa). In...

The relative magnitude of general combining ability (gca) and specific combining ability (sca) effects in three generations (years), viz. Seedling (SG), first clonal generation (FCG) and second clonal generation (SCG) for tuber yield, tuber number, average tuber weight and tuber dry matter of potato in a line x tester mating design (10 × 4) was studied. There were marked differences in the gca ...

We evaluate background rejection capabilities and physics performance of a detector composed of two diverse elements: a sensitive target (filled with one or two species of liquefied noble gases) and an active veto (made of Gddoped ultra-pure water). A GEANT4 simulation shows that for a direct WIMP search, this device can reduce the neutron background to O(1) event per year per tonne of material...

Materials and methods: Ninety-six crossbred pigs 17 to 20 days old were randomly assigned to six experimental diets. A nonmedicated basal diet was supplemented with carbadox (55.12 g per tonne), copper sulfate (192.40 g copper per tonne), zinc oxide (2712.68 g zinc per tonne), or the probiotic feed additive BioPlus2B (Chr Hansen Inc, Milwaukee, Wisconsin; 1.1 × 106 or 1.3 × 106 spores per gram ...

21 kilometres north of Stewart (Figure 2-IZ-l), on the east The Silbak Premier mine is in northwest British Columbia, side of the Salmon River Valley. The original discovery of a that from 1918 to 1953 produced 4.3 million tonnes of ore high-grade vein in 1910 culminated in an underground mine grading 14.6 grams gold and 304 grams silver per tonne from sulphide-bearing stockworkveins and brecci...

In Ardabil region potato crop needs several irrigation, however ground water supplies arebeing exhausted due to reduced precipitation and intensive irrigation. In this research droughttolerance of 10 commercial potato cultivars was studied at three irrigation treatments (100%,80% and 60% of required irrigation water) in Ardabil in a two years field study, 2013-2014.At harvest, marketable tuber ...
