a pure silicate host namely sr2mgsi2o7 as a support for a long-lasting afterglow when dopped with rare-earth elements was sought after. to this end the process of obtaining firing temperatures of the above mentioned phase in normal condition was carried out using suggested wet and dry methods. the degree of purity obtained in these preparatory methods as well as the different firing temperature...

background : in many jobs, individuals are exposed to thermal stress, and thus, evaluation of heat stress is necessary. this study was conducted with the purpose of investigating the relationship of perceptual strain index (pesi) with other heat indexes under hot laboratory conditions. methods: this empirical-experimental and cross-sectional study was performed in 5 different temperatures (21 º...

abstract background: heat is one of the most important of harmful agents in many working environments such as bakeries that can cause prevalence of diseases related to heat and falling of efficiency. aim of this study was exposure evaluation of isfahan bakers to heat stresses in their working environment through evaluation of relationship among wet bulb globe temperature index (wbgt) , oral tem...

Gas turbine systems with wet compression have a potential for future power generation, since they can offer a high efficiency and a high specific power with a relatively low cost. In this study influence of ambient condition on the performance of the wet compression process is investigated with a non-equilibrium analytical modeling based on droplet evaporation. Transient behaviors of droplet di...

The U.S. Army has a need for continuous, accurate estimates of the wet bulb globe temperature to protect soldiers and civilian workers from heat-related injuries, including those involved in the storage and destruction of aging chemical munitions at depots across the United States. At these depots, workers must don protective clothing that increases their risk of heat-related injury. Because of...

With the development in egocentric vision, skill measurement has been recently proposed as a novel topic in this emerging field. In this report, we record the the experimenter’s first-person videos in Wet labratories (wetlab), and measure his/her operative skills. Specifically, given the videos of expert and amateur, we analyze their head motions, hands motions, eye-hand coordinations and key-m...
