It has been reported that in different regions and sowing dates, the response of crops to past climate change is not the same, due to different rates of decrease/increase in each climatic variable at different regions and months of year. This study was aimed to assess the effect of individual versus simultaneous changes in solar radiation (S), precipitation (P) and temperature (T) on rainf...

Twin screw extrusion based pretreatment of biomass is an attractive option due to its flexibility to carry out chemical reactions under relatively high stresses, temperatures and pressures. However, extrusion processes are rarely utilized in biomass pretreatment because such processing is constrained by rheological behavior of typical biomass suspensions. Without the manipulation of their rheol...

the main objective of this study was to determine the influence of vermicompost and biostimulant on the growth and biomass in the coriander plant height, wet weight of plant ,dry weight of plant and biomass yield. the experiment was carried out as factorial experiment in the base of randomized complete blocks design with eight treatments and three replications at research field of agriculture c...

in this study, feasibility of upgrading and retrofitting municipal wastewater treatment plantswas investigated at laboratory scale using moving bed biofilm reactor (mbbr) process. for this purpose,an aerobic pilot was operated for nearly one year in different conditions, in which a moving bed carrier with aspecific biofilm surface area of 500 m2/m3 and a filling rate of 60% was utilized. system...

the models oryza2000, swap and wofost simulate the growth and development of rice under conditions of potential production and water limitation. the models were evaluated against a data set of field experiments. the study was laid out in rcbd with three replications for one traditional landrace, hashemi, carried out in 2005 at the rice research institute of iran in rasht. the irrigation managem...

Biomass accounts for an estimated one-third of all energy used in developing countries today. Most of this biomass is used inefficiently and with significant pollutant emissions by the more than 2 billion people who cook using direct combustion of biomass. Contrasting today’s use of biomass energy, several recent major assessments of future global energy supply show much larger roles for biomas...

Biomasses are organic materials that are derived from any living or recently-living structure. Plenty of biomasses are produced nationwide. Biomasses are mostly combusted and usually discarded or disposed of without treatment as biomass ashes, which include wood and sugarcane bagasse ashes. Thus, recycling or treatment of biomass ashes leads to utilizing the natural materials as an economical a...

Biomass is the oldest form of energy used by human beings, mainly in the form of wood. It is a renewable source of energy and has many advantages from an ecological point of view. The direct combustion of biomass generates concern among environmentalists, as it is incomplete and inconsistent and may produce organic particulate matter, carbon monoxide and other organic gases. Biomass gasificatio...

In the context of mitigating climate change and increase energy security, the utilization of biomass in the energy sector is expected to play a major role. However, to estimate the possibility of fulfilling national goals concerning the future use of biomass sources and to estimate the future use of biomass sources in the energy sector, the current energy system models needs to be further devel...
