Most concrete structures and buildings are under temperature and moisture variations simultaneously. Thus, the moisture transport in concrete is driven by the moisture gradient as well as the temperature gradient. This paper presents an experimental approach for determining the effect of different temperature gradients on moisture distribution profiles in concrete. The effect of elevated temper...

The purpose of this study is to determine the temperature influence on the soil bulk dielectric permittivity, ε b, calculated from the measurement of the electromagnetic wave velocity of propagation along the parallel waveguide in a TDR probe, i.e. a probe working in Time Domain Reflectometry technique. The experimental evidence shows that the existing models do not completely describe the temp...

vacuum drying of salicornia herbacea l. was performed at different drying temperatures (50, 60, 70, and 80c) to evaluate the drying characteristics and the effect of drying temperatures on the quality of salicornia. as the drying temperature increased, the drying time decreased significantly (p< 0.05). the drying rate decreased with decrease in moisture content and increase in drying time. on ...

adverse environmental storage conditions including high temperature and relative humidity could affect seed quality. the objective of this investigation was to quantify relationship between temperatures and seed moisture on seed deterioration and determination viability constants in sorghum. four storage temperatures (5, 15, 25 and 35oc) and three moister content levels (6, 10 and 14%) were use...

Convective air drying characteristics of mango slices at different drying temperatures (60°C, 70°C and 80°C), at an air velocity of 0.5 m/s and for constant sample thickness (3 mm) were investigated. Results indicated that drying took place in the falling rate period. Drying time decreased considerably with increased drying temperature. Three mathematical models; namely, Newton (Lewis), Henders...

Spontaneous combustion of coal is one of the most horrifying hazards in coal industries, especially in underground coal mines. Thus having a prior knowledge about the occurrence of this phenomenon in underground coal mines is of crucial importance in preventing this process, loss of life, huge economic loss, and environmental pollution. The aim of this work is to determine the spontaneous combu...

wheat germ is a by-product of milling industry rich in fiber, tocopherol, unsaturated fatty acids, polyphenol, minerals and protein. in this study, effect of adding raw and stabilized wheat germ on the characteristics of cake batter such as specific gravity, viscosity and cake properties such as volume, apparent density, solid density, porosity, water activity, moisture and firmness was studied...
