Emissivity and Dielectric Behavior of Red Soils of Dhule District at X-band Microwave Frequencies
Abstract: Using X-band (8.2 and 10.5GHz) experimentation, the fluctuation of the dielectric constant (ε’) and dielectric loss (ε’’) of soil samples with different moisture contents has been determined. After reaching a transition point, the value of (ε') grows gradually with moisture content before increasing quickly after that. The emissivity has been estimated from experimentally determined (ε’) using emissivity model for vertical polarization. The findings indicate that as MC/dielectric constant increases, emissivity …

Surface Modified Abaca Fibers: Physico-Mechanical, Morphological and Degradation Properties Evaluation
Abstract: Lignocellulosic fibers are used as cost-cutting fillers in plastics factories. Amid several factors, the ultimate performance of composite ingredients depends on the bond between the matrix resin and the filler, and hence on the quality of the interface. To acquire optimal performance of the end product, adequate interaction between the matrix and the lignocellulosic ingredient is preferred. This is often acquired through surface modification of the matrix or filler. Abaca …
