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...

In-duct ultraviolet germicidal irradiation (UVGI) systems treat moving air streams in heating, ventilation, and air-conditioning (HVAC) systems to inactivate airborne microorganisms. UVGI system performance depends on air temperature, velocity, cumulative operating time, variations in exposure time and other factors. Annual simulations of UVGI efficiency and space concentration that accounted f...

INTRODUCTION Diseases of the pleural space, including pneumothorax, pleural effusion, and space occupying mass lesions (tumor, diaphragmatic hernia) are relatively common disorders in small animal clinical practice. The abnormal presence of air, fluid and/or tissue within the pleural cavity does not generally reflect disease of the pleura per se; but instead represents a disorder of the airways...

Background: Unusual enlargement of nasopharynx can disrupt air flow through the nose. The aim of this study was to investigate the cephalometric parameters in the upper airways. Methods: This retrospective descriptive study was conducted on 32 adults with Class II malocclusion without the history of night apnea in Qazvin. The radiographs were obtained from the...

Consider a viscous liquid droplet spreading on a surface. The classical slip condition at the liquid–solid interface is the no–slip condition. However, this condition lead to infinite dissipation of energy for propagating contact lines (“no–slip paradox”). For this reason other slip conditions such as the Navier–slip have been introduced. We prove well–posedness for a reduced 1–d fluid model mo...

This paper focuses on the relationships between stratified $L$-conver-gence spaces, stratified strong $L$-convergence spaces and stratifiedlevelwise  $L$-convergence spaces. It has been known that: (1) astratified $L$-convergence space is precisely a left-continuousstratified levelwise $L$-convergence space; and (2) a  stratifiedstrong $L$-convergence space is naturally a stratified $L$-converg...

are caused by trauma or iatrogenic interventions, and to the best of our knowledge, only 17 cases associated with bronchial asthma have been reported in the literature up to February 2012. The mechanism by which this condition is considered to develop is the exfoliation of transudative air in the posterior mediastinum space due to high bronchoalveolar pressure, and the subsequent invasion of th...
