A molecular model involving only hydrogen bond interactions is successful in explaining the effects of temperature and moisture on the elastic modulus of paper. Concepts of glass transitions, free volume, and plasticization help explain the role of temperature and moisture in affecting paper’s properties in terms that elicit the importance of paper’s macromolecular structure. Ultimate strength ...

The purpose of this study was to investigate the effect of process conditions on the properties of instant grain base. A blend of wheat, mungbean and groundnut was used in the study. The effects of feed moisture, barrel temperature and screw speed on product responses viz. specific mechanical energy (SME), expansion ratio (ER), density (D), water absorption index (WAI) and water solubility inde...

Open sun drying (OSD) is the most common method of crop drying in developing countries. Despite several disadvantages, it is widely practiced because it is a simple way of drying. Crop temperature, temperature around the crop, solair temperature, and rate of moisture evaporation are the important parameters in OSD. The thermal behavior of OSD of green chillies, green pea, white gram (kabuli cha...

To develop advanced pasteurization treatments based on radio frequency (RF) or microwave (MW) energy, dielectric properties of almond kernels were measured by using an open-ended coaxial-line probe and impedance analyzer at frequencies between 10 and 3000 MHz, moisture contents between 4.2% to 19.6% w.b. and temperatures between 20 and 90 °C. The results showed that both dielectric constant and...

different control strategies of bed temperature and moisture were investigated using various inlet air temperatures and air fluxes in both the ordinary packed bed bioreactor (without cooling water in the jacket) and the bioreactor with cooling water in jacket. the experiments were carried out within a 1-l solid-state packed bed bioreactor in which aspergillus niger was cultivated on wheat bran....

Ecosystem respiration (ER) was measured with the eddy covariance technique in 14 forest ecosystems in the Upper Great Lakes Region during the growing seasons of 2002 and 2003. The response of ER to soil temperature and moisture was analyzed using empirical models. On average, ER was higher in the intermediate and young than in the mature stands, and higher in hardwood than in conifer stands. Th...

Twenty six 3.8 kg blocks were made on each of 3 different days. A block was analyzed prior to brine salting. Blocks (5) were placed into each of 5 different saturated brines at 12, 15, 18, 21, and 24◦C. One block was removed from each brine tank after 1, 4, 8, 16, and 24 d, weighed, sampled, and analyzed for salt and moisture. Weight loss (net of moisture loss and salt uptake), salt uptake, and...

introduction: using oilseeds in the human food stuffs, employing their meal for animal feed and also their usage in pharmaceuticals, soap making and fuel has prompted great interest for farmers to plant them and for the government to promote their cultivation. among them, sunflower is one of the main oilseeds in the world which its cultivated area has expanded due to fair cultivation requiremen...

This paper investigates a simplified polarimetric decomposition for soil moisture retrieval over agricultural fields. In order to overcome the coherent superposition of the backscattering contributions from vegetation and underlying soils, a simplification of an existing polarimetric decomposition is proposed in this study. It aims to retrieve the soil moisture by using only the surface scatter...
