Bed bugs, Cimex lectularius L., hide in cracks and crevices in furniture and are difÞcult to control. The bed bug thermal death kinetics were examined to develop a heat treatment method to eliminate bed bug infestations in room contents. High temperatures caused temporary immobilization (knockdown) of bed bugs evenwith exposures that did not have lethal effects. Exposure of bed bug adults to 39...

Heat illness spans a broad spectrum of disease, with outcomes ranging from benign rash to fatal heat stroke. Heat illness is broadly divided into 2 types: classic and exertional. Both types occur as a result of exposure to elevated temperature with inadequate thermoregulation; however, classic illness occurs without preceding physical activity. Treatment consists of rapid cooling, fluid replace...

The lattice Boltzmann method (LBM) was used to analyze two-dimensional (2D) non-Fourier heat conduction with temperature-dependent thermal conductivity. To this end, the evolution of wave-like temperature distributions in a 2D plate was obtained. The temperature distributions along certain parts of the plate, which was subjected to heat generation and constant thermal conductivity condit...

in this research, tribological characteristics of ni-p electroless coating and double-layered ni-p/ni-b electroless coating were studied. for this purpose, ni-p electroless coating with 25 μm thickness was initially applied to the surface of steel ck45 samples; then, a double-layered ni-p/ni-b electroless coating, including inner layer of ni-p with 15 μm thickness and outer layer of ni-b with 1...

objective(s): hyperthermia is one of the most common environmental stressors that affect multi-biological systems in the body including the central nervous system as well as the hematopoietic organs. the objective of the present study was to investigate the protective role of ethanolic extract of propolis (eep) on some selective stress markers, hematological, biochemical, and histopathological ...

Mechanical properties of dissimilar weld joints between GOST09ch16N4B (a martensitic stainless steel) and AISI 4130 thin sheets made by gas tungsten arc welding (GTAW) were studied using ER410NiMo and ER100S-G filler metals in post weld heat treated conditions. Heat treatment cycles consisted of austenitization at 900, 950 and 1000 °C for 1 h and this was followed by oil cooling and tempering a...

abstract: in this paper, a new population-based search called the bees algorithm (ba) is presented to estimate the time-dependent heat transfer coefficient and the corresponding heat flux at the boundaries of a two-dimensional body subjected to transient heat conduction, using the temperature measurements at discrete nodal locations on the boundaries, where heat flux is specified as the boundar...

The main task of this work was to study the influence of the cooling conditions after homogenization of the 6082 aluminium alloys. The effect of the solution heat treatment temperature on the mechanism and ageing kinetics of the two commercial wrought aluminum alloys 6005 and 6082 was also analyzed. The alloys were heat treated—T4 with a wide range of solution heat treatment temperature from 51...

CaCO3 nanoparticles have been synthesized via heat-treatment of a new precursor and solid state reaction. Effect of calcinations temperature and quantity of surfactant on particle size has been investigated. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared (FT–IR) spec...
