Nine Aspergillus and three of Trichoderma strains were grown on wheat bran (WB) medium under solid state fermentation (SSF) for amylase production. Aspergillus oryzae LS1 produced the highest level of the enzyme. The thermal stability profile of its crude enzyme revealed the half-life time of more than 2 h at 50 and 60oC. The enzyme production was affected by strain type, incubation periods, le...

The feasibility of high-rate composting of barley dregs and sewage sludge was examined using a pilot scale bioreactor. A central composite design (CCD) was used to optimize the mix ratio of barley dregs/sewage sludge and moisture content. The performance of the bioreactor was monitored as a function of carbon decomposition rate (CDR) and total volatile solids (TVS) loss rate. The optimum range ...

Leaks represent a very important hazard for the buildings and they can affect all sorts of building materials and specially wood due to its hygroscopic properties. Excessive moisture content can affect in a negative way building processes such as the installation of wooden floors or the use of wood as a structural material. Moisture meters can provide prompt and non-destructive determination of...

Defatted rice bran was incorporated with cereal base by an extrusion process to obtain a functional, ready-to-eat breakfast cereal. This study investigated the effects of defatted rice bran content (10, 15 and 20%), the sixth barrel temperature (H6: 130, 140 and 150oC), and feed moisture content (14, 17 and 20%) on the physical and functional properties of extrudates in breakfast cereal product...

In this research a laboratory investigation has been performed on the soil from different locations of Gujarat, India to Correlate Optimum moisture content (OMC) Dynamic Cone Penetration (DCP) test values with strength parameters of subgrade. In-situ condition has been made in laboratory using bigger testing mould and various tests like Liquid Limit, Plastic limit as well as CBR, PBT, UCS and D...

Forest roads play an important role in forest management, timber transportation and forest protection. However, minimum standards are considered for pavement materials due to the traffic volume and economic situation of forestry projects. Therefore, this paper aims to (a) evaluate the role of Rice Husk Ash (RHA) as a soil stabilizer of sub-base layer to improve the quality of materials and (b) ...
