Europe is committed to a new growth strategy with no net greenhouse gases emissions by 2050, where hydrogen has clear role play. Portugal's for H2 sets public policies promoting an industry focused on the value chain. Considering production of green from renewable sources key, water electrolysis becomes priority, and it, need assess suitability sources, which determined both quantitative qualit...

effects of condensed tannins (ct) on crude protein availability in sainfoin hay was investigated according to most popular ruminant feeding systems. different treatments including polyethylene glycol (6000 mw), sodium hydroxide, sodium bicarbonate, potassium permanganate, wood ash, water and urea, were applied for deactivation of ct crude protein fractioning was determined using nylon bag techn...

[1] Farmers make joint water and land use decisions for economic purposes based in part on water availability and reliability. A two-stage economic production model is developed to examine the effects of hydrologic uncertainty and water prices on agricultural production, cropping patterns, and water and irrigation technology use. The model maximizes net expected farm profit from permanent and a...

in this study, to determine the economic value of irrigation water and simulate the response of farmers to reducing  available water policy of positive mathematical programming models (pmp) was used. by the proposed model, the economic value (shadow price) of irrigation water estimated in each of the areas of western rodbar alamuot, rajai dasht and eastern rodbar almuot. then, the reactions of ...

Root responses to differences in availability of nitrogen and soil water were studied in loblolly pine (Pinus taeda L.) seedlings grown in monoculture and in competition with sweetgum (Liquidambar styraciflua L.) or crab grass (Digitaria spp.). Rhizotron cells were maintained at high soil water availability (approximately -0.1 MPa) or subjected to three dry-down cycles to low soil water availab...

abstract- efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. this research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (wp) with different water management scenarios at farm level at ...

The use of hydration and solvatation free enthalpies (DeltaG(h), DeltaG(s)) as parameters describing water solubility and permeability of drugs was proved to be suitable quantities. The free enthalpies of hydration and solvation by water and chlorobenzene molecules at the Hartree-Fock (6-31G*) level applying PCM model were calculated for oxyconazole and tioconazole. The oxyconazole and tioconaz...
