As s‌tudents spend one-third of their time at school, their health, comfort, and productivity are mos‌tly influenced by thermal condition and indoor air quality of classrooms. Regarding that manual window-opening is a common way for providing fresh air in classes and s‌tudents aren't allowed to change their uniform, position or control the windows during the lesson hours, providing thermal comf...

high moisture levels in fresh dairy manure provide a suitable environment for growth of pathogens and cause environmental pollution. dry manure can be used for different purposes in agriculture and in livestock industry. such heat properties of manure as specific heat, thermal conductivity and thermal diffusivity are important needed factors for the design and development of a suitable efficien...

This paper describes a series of field studies and simulation analysis to improve the thermal performance of school buildings in the city of Tehran in Iran during warm season. The field studies used on-site measurement and questionnaire-based survey in the warm spring season in a typical female secondary school building. The on-site monitoring assessed the indoor air temperatures and relative h...

A model of fractional-order of thermoelasticity is applied to study a 2D problem of mode-I crack in a fibre-reinforced thermal environment. The crack is under prescribed distributions of heat and pressure. The normal mode analysis is applied to deduce exact formulae for displacements, stresses, and temperature. Variations of field quantities with the axial direction are illustrated graphically....

Computational fluid dynamics (CFD) simulations of thermal manikins can provide detailed information which it is impossible to obtain from experiments. In this review several issues from CFD studies of thermal manikins are discussed, such as geometric complexity of computational thermal manikins (CTMs), selection of turbulence models, grid generation and boundary conditions. Calculation of CTMs ...

Inhalable particulate matter (PM10) is a primary air pollutant closely related to public health, and an especially serious problem in urban areas. The urban heat island (UHI) effect has made the urban PM10 pollution situation more complex and severe. In this study, we established a health risk assessment system utilizing an epidemiological method taking the thermal environment effects into cons...

According to recent reviews, the question of how trophic interactions may affect evolutionary responses to climate change remains unanswered. In this modelling study, we explore the evolutionary dynamics of thermal and plant-herbivore interaction traits in a warming environment. We find the herbivore usually reduces adaptation speed and persistence time of the plant by reducing biomass. However...
