Cabin air quality and thermal conditions have a direct impact on passenger flight crew’s health comfort. In this study, in-cabin environment particulate matter (PM) exposures were investigated in four China domestic flights. The mean standard deviation of the carbon dioxide (CO2) concentrations two tested flights are 1440 ± 111 ppm. measured maximum monoxide (CO) concentration is 1.2 ppm, which...

In this article the place and capacity of combined heat and power [CHP] prediction unit wasdetermined dynamically with use of modified particle swarm optimization (MPSO). It was done inoptimization palace and with a capacity of CHP as a production resource with the aim to increasethe reliability capacity. Decrease the loss and provide the electrical and thermal energies ofindustrial city. The f...

In this study the thermal conductivity and the volumetric heat capacity of non-Newtonian fluids are investigated. These fluids find many applications in chemical, medical and food industries. They mostly have viscoelastic behavior and generally differ from Newtonian fluids. Two non-Newtonian fluids, solutions of xanthan and carboxy methyl cellulose in water with various concentrations have bee...

Auckland has a temperate climate with comfortable warm, dry summers and mild, wet winters. Auckland house design not only focus on winter thermal performance and indoor thermal condition, but also indoor moisture control, which is closely related to indirect health effects such as dust mites, fungi, etc. Most Auckland houses are designed to use temporary heating for winter indoor thermal comfor...

from building design point of view a basic aim of low energy architecture is to create a thermally comfortable internal environment for building occupants whilst consuming the least possible amount of energy. thus, thermal comfort study has an important impact on energy saving. achieving comfort conditions requires an understanding of the interaction between three groups of factors, namely phys...

background: enzymes are well known as sensitive catalysts in the laboratory and industrial scale. to improve their properties and for using their significant potential in various reactions as a useful catalyst the stability of enzymes can often require improvement. enzymes immobilization on solid supports such as epoxy- functionalized ferric silica nanocomposite can be effective way to improve ...
