The present study aims at investigation of the performance of nanofibrous filter, containing magnesium oxide (MgO) nanoparticles, for bioaerosols removal from the air stream. It synthesizes two types of polyacrylonitrile (PAN) and PAN/MgO nanofibers via electrospinning technique, and investigates the antibacterial properties of the produced nanofibers through disk diffusion. The air containing ...

UNLABELLED This study, a randomized controlled trial, evaluated the effectiveness of free-standing air filters and window air conditioners (ACs) in 126 low-income households of children with asthma. Households were randomized into a control group, a group receiving a free-standing HEPA filter placed in the child's sleeping area, and a group receiving the filter and a window-mounted AC. Indoor a...

BACKGROUND During general anesthesia, a heated breathing circuit (HBC) is used to replace the heat and moisture exchange function of the upper airway. One HBC uses an air dryer filter that employs silica gel (SG) as a desiccant. SG is capable of adsorbing many organic compounds. Therefore, we undertook an in vitro study of the adsorption of desflurane by SG filters. METHODS An HBC was connect...

Gaseous microemboli have been associated with post operative neurological deficits in patients undergoing cardiopulmonary bypass. Creating an optimal perfusion system that minimizes microemboli production and has enhanced abilities to sequester entrained air during the bypass procedure has been an important focus. This study examines the air-handling capabilities of a cardiopulmonary bypass cir...

Fenomena yang ada bahwa air tanah di daerah komplek kampus terpadu UPN Veteran Yogyakarta berbau dan berwarna coklat kemerahan, apabila tersebut juga menimbulkan endapan pada bak penampung air. Berdasarkan fenomena tersebut, maka diduga mengandung zat besi (Fe) Mangan (Mn) cukup tinggi. Guna mengatasi hal diperlukan upaya mereduksi kadar sesuai dengan peraturan disyaratkan. Fokus utama dari pen...
