agglomeration followed by pelleting is an efficient method to decrease transport costs and increase economic efficiency of composting municipal waste. the moisture content of compost is the most important parameter of the pellet making process for any type of manufacturing device. the experiments in this study were done at moisture contents of 35%, 45% and 50% at extruder shaft rotational speed...

the engineering properties of soils are generally affected by parameters such as mineral type, structure, and pore water salinity. the existing solutes of soil play a role in the electrochemical forces between particles and can change the index and mechanical properties of soil, including cohesion, compressibility, and compactibility. this study investigated the effect of sodium chloride, sodiu...

in some conditions, to avoid deterioration and field losses of soybean seeds (glycine max merr.) from weathering at end of the season, farmers start to harvest seeds with a high moisture content and so, careful post-harvest drying would be required to maintain the physiological quality of seeds. response surface methodology (rsm) was used to optimize the operating conditions of soybean seed dry...

effect of different ratios of sucrose to fruit concentrate (orange and sour cherry), level of cacl2 (0-2%) and storage time (0-90 days) on physicochemical properties of candied apples were investigated using of a combined design. different quality indices such as total sugars content, ascorbic acid, color attribute (chroma) and overall acceptance were modeled and then multiobjective optimizatio...

the accuracy and effectiveness of precision agriculture is highly depending on accuracy and time analysis of the soil moisture conditions. monitoring of the soil water status is a proper method for optimizing the agricultural irrigation. automation irrigation, based on soil moisture measurement by smart sensors has the potential to provide maximum water use efficiency by maintaining soil moistu...

in this study, the effects of moisture content and corn variety on the physicochemical properties of popcorn were investigated and modeled using response surface methodology. each of the two corn varieties (hybrid corn ksc 600 pc and american) was prepared with a range of moisture (six moisture levels ranging from 10 to 20%) and popped by a hot air popper. variety and moisture content affected ...

A sludge composite modifier SCM which comprises a mixture of three cementitious components was proposed for sludge drying and stabilization. Effect of SCM components on sludge moisture content was analyzed using uniform design and the optimum composition of SCM was determined by computer-aided modeling and optimization. To compare the drying effect of SCM, quicklime, and Portland cement, the ef...

L-methioninase has received much attention for its tumor selective anticancer activity. This study investigates the production and optimization of extracellular L-methioninase enzyme using several agro-industrial residues by Aspergillus flavipes MTCC 6337 using SSF (solid state fermentation). Effect of process variables namely substrates, incubation period, temperature, moisture content, inocul...

different additives have been considered to improve stabilization of the engineering properties of fine-grained soil. the present study investigated the effect of the addition of sewage sludge ash on the compressive strength of clay soil at optimum moisture content and under saturated conditions. the four treatments tested were the addition of 0%, 5%, 10% and 15% sewage sludge ash to clayey soi...
