A significant amount of heat is wasted in manufacturing process, electricity generation, chemical and industrial process. Recovery and reuse of this energy through storage can be useful in conservation of energy. In the present study, a double pipe type heat exchanger has been designed and fabricated for low temperature industrial waste heat recovery using phase change material (PCM) paraffin w...

It is important to evaluate whether an ice thermal storage system can operate effectively as the way planned at the design stage. While designing an ice thermal storage system, generally, the thermal storage time is calculated by using rated capacity of refrigerator or the heat exchange capacity of ice-on-coil, and the heating capacity time is calculated by using the average ice melting ability...

Raw poultry carcasses are often contaminated with pathogens, including Salmonella spp., Campylobacter jejuni and Listeria monocytogenes. Campylobacteriosis is an emerging and one of the most frequently reported zoonotic infectious disease. Further to the best management practices in husbandry, slaughtering and processing, decontaminating treatments might be required to control microbial hazards...

During early 1990s, there were 30 million patients with epilepsy in the world1. They require long-term medication with various antiepiletic formulations. The efficacy of various therapeutic formulations being offered to those suffering from an epileptic disorder (Table 1) could be severely lowered in the face of impending global warming and frequent occurrence of the El niño effects. Even thoug...

Administration of a birth dose of hepatitis B vaccine (HepB vaccine) to neonates is recommended to prevent mother-to-infant transmission and chronic infection with the hepatitis B virus (HBV). Although manufacturers recommend HepB vaccine distribution and storage at 2-8 degrees C, recognition of the heat stability of hepatitis B surface antigen stimulated research into its use after storage at,...

Aims: The objective of this study was to determine the influence of mild heat treatment, storage temperature and storage time on the survival and growth of Listeria monocytogenes inoculated onto cut iceberg lettuce leaves. Methods and Results: Before or after inoculation with L. monocytogenes, cut iceberg lettuce leaves were dipped in water (20 or 50°C), containing or not 20 mg l chlorine, for ...

We examined whether older individuals experience greater levels of hyperthermia and cardiovascular strain during an extreme heat exposure compared to young adults. During a 3-hour extreme heat exposure (44°C, 30% relative humidity), we compared body heat storage, core temperature (rectal, visceral) and cardiovascular (heart rate, cardiac output, mean arterial pressure, limb blood flow) response...
