ABSTRACT- Many fruits, vegetables and ornamental crops of tropical origin experience physiological damage when subjected to low temperatures. Protection of plants from the effects of lethally low temperatures is important in agriculture, especially in horticultural production of high value fruits and vegetables. The objective of this study was to develop a simple model to predict the daily mini...

abstract germination and emergence of cold tolerant lentil genotypes sometimes experiences low temperatures and variable rainfalls in the fall planting. this study was conducted to evaluate the effects of drought stress on germination stage of lentil genotypes. experiment was carried out with 18 lentil genotypes under five levels of water potential (0 , -0.4 , -0.8 , -1.2 , -1.6 mpa) using peg ...

production of thermostable alkaline protease in tray bioreactor for solid state fermentation is a unique process which may lead to an economical approach for production of enzyme from agricultural waste or low cost substrate. in solid state fermentation using tray bioreactor, several agricultural residues such as rice bran, sugarcane bagasse, wheat bran, barely bran, corn meal and corn husk wer...

It has long been known that temperature during circulation and after cement placement is one of the most important parameters for slurry design and the success in cement production. Conventional cements and low density cement slurries usually take a long time to set and cannot provide significant compressive strength. Therefore, it is important to design appropriate low density cement slurries ...

Background: In Algeria the date wastes production is estimated at least 85.000 tones. Date wastes is an economic source of carbohydrates for conversion to industrial enzymes because it is readily available and relatively low priced. Objective: The aim of the present study was to investigate the potential of using date wastes as a substrate for the production of a-amylase and invertase. Materia...

cell lines derived from mammalian are dominant systems for the production of recombinant therapeutic proteins because of their capacity for correct protein folding, assembly and post-translational modification. in the search of an efficient method for the production of  a recombinant protein using animal cell culture, we investigated the effects of different treatment including fetal calf serum...

abstract: minimizing the work consumed in refrigeration system is the most effective measure to reduce the cost of products in sub-ambient chemical processes. the introduction of mixed working fluids into refrigeration system in place of pure working fluids is a recent advancement applied in the field. due to the lack of systematic design method for mixed refrigerant cycle (mrc), conventional a...

in this study, bio-based carbon nanotubes (cnts) have received considerable research attention due to their comparative advantages of high level stability, simplistic use, low toxicity and overall environmental friendliness. new potentials for improvement in heat transfer applications are presented due to their high aspect ratio, high thermal conductivity and special surface area. phonons have ...

in order to establish the appropriate methane fermentation technology for low strength wastewater, a 2.0 l egsb reactor was operated at 20â°c with 0.3 - 0.4 g cod/l of sucrose-based synthetic wastewater for 500 days. at the start up period, the reactor was operated in egsb mode with a 5 m/h up flow velocity by continuous effluent recirculation. however, the egsb reactor exhibited insufficient c...
