Aim of the study: The aim of this study was to develop a model for above-ground biomass estimation for Pinus radiata D. Don in Asturias. Area of study: Asturias (NE of Spain). Material and methods: Different models were f itted for the different above-ground components and weighted regression was used to correct heteroscedasticity. Finally, all the models were refitted simultaneously by use of ...

Bagasse as a real biomass was converted to hydrogen rich gas via catalytic supercritical water gasification process. To find the effect of Cu on selectivity of products, Cu promoted Ni-γAl2O3 catalysts were prepared with 1 to 20wt% Ni and 0.5 to 10wt% Cu loadings via impregnation method. Catalysts were characterized by ICP, BET, XRD, H2 chemisorption and TEM technique as well CHNS analysis was ...

in this paper, the electrical consumption of a research center building is derived of the bills, then with defining of fuzzy bus thermal coefficient objective function for heating, the amount of available heat selling to research center building consumer that is produced by biomass solar hybrid source is calculated. with the capacity determination of biomass solar hybrid source to provide therm...

to study the physiological effects of different levels of salt stress on germination and on seedling stages, two seperate experiments were undertaken in rice research institute of iran, amol in 2006. the experiments were conducted in a completely randomized design of three replications in greenhouse. sixteen rice genotypes namely: ahlamitarum, shafagh, gharib, taromzavarak, khazar, mosatarom, g...

Variation of hydrochemical conditions, with special reference to adequacy of waters as fish habitats, was traced based on selected hydrochemical parameters obtained during the studies conducted from February 2013 till February 2014 year. The results were compared with earlier studies. The sources of organic pollution were identified, and the effect of biogenic substances on the biomass, as well...

Land consolidation changes the land use types and then the biomass. The measure and calculation of biomass fore-and-aft land consolidation worked out by the sample plot method in terms of arbor, shrub, herbage plants and crop. The result shows that the biomass is increased 580 t after land consolidation, meaning the impression of land consolidation is remarkable in general. The results of monom...

this study investigated the effect, on reactor performance and biomass retention inside the bed, of the material used to make the supports of anaerobic fixed-bed reactors. three inert supports of similar shape but made of three different materials polyvinyl chloride, polypropylene, high-density polyethylene were manufactured and used. all three supports had the same specific surface area but di...
