The present study aims to measure the technical efficiency and establish core factors affecting rice production in Cambodia. A four-year dataset generated from the central government document “Profile on Economics and Social” of 25 entire provinces between 2012 and 2015 and the stochastic production frontier model (SFA) was applied. The results indicated that the level of output (quantity) of C...

abstract a basic aim of low energy architecture is to create a thermally comfortable internal environment for building occupants whilst consuming the least possible amount of energy. in desert countries this aim is more difficult to achieve since high ambient air temperatures create a barrier to comfort. traditional building types of these countries, such as courtyard building, have evolved to ...

No-cook process using granular starch hydrolyzing enzyme (GSHE) was evaluated for Indian broken rice and pearl millet. One-factor-at-a-time optimization method was used in ethanol production to identify optimum concentration of GSHE, under yeast fermentation conditions using broken rice and pearl millet as fermentation feedstocks. An acid fungal protease at a concentration of 0.2 kg per metric ...

Natural coagulants have received much attention for turbidity removal, thanks to their environmental friendliness. The present study investigates potential application of rice starch for removal of turbidity from aqueous solutions. It considers the effects of four main factors, namely settling time (40-140 min), pH (2-8), slow stirring speed (20-60 rpm), and rice starch dosage (0-200 mg/L), eac...

Almost ten years have elapsed since the initiation of experiments on rice transformation using Agrobacterium tumefaciens. Chen et al. successfully transformed rice using this method, but transformation efficiency was low. After Hiei et al. reported high efficiency of Agrobacterium-mediated production of fertile and heritable transgenic rice plants, this technology was adopted by many laboratori...

climate change and its possible impacts on the environment and socio-economic systems now constitute the most important environmental problem facing mankind in the 21st century. climate change will increase poverty and hardship, endanger food security, destabilize economies, decrease food and water and create social insecurity in many countries and undermine our goals for achieving sustainable ...

background & aim: energy is one of important debates in agriculture ecology and for this reason; the ratio of output and input energy in different agriculture ecosystems has been calculated. if one can reduce, input energy level into farms through the indices like poisons, fertilization, tractor energy and lab our force. in addition to the net income of the farmers, this issue would play a ...
