Abstract:
... The feasibility of radio frequency (RF) selective heating as a disinfestation technique was investigated, considering rusty grain beetle in bulk wheat samples at 27.12 MHz. Although pesticides and fumigants are the most commonly used methods for controlling insects in postharvest products such as grains, nuts, and fruits, they pose a direct threat to human health and the environment. In this work, ...

Abstract:
... In this study, thermal energy storage cement-based composite (TESC) was developed by incorporating paraffin/diatomite (DP) composite phase change material (PCM). Paraffin/DP composite PCM was firstly fabricated at mix proportion (paraffin: DP) of 0.9:1.0. Scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) results show that paraffin can be well impregnated into DP pores and h ...

Abstract:
... A methodology for the GIS (Geographic Information System) based analysis of DH (District Heating) potentials is introduced and applied to the continental United States. The energy demand for space heating and hot water in the residential and commercial sector is assessed and spatially allocated using high resolution population distribution and land use data. Demand centers are identified and the o ...
