Airborne virus capture and inactivation were studied in an electrostatic precipitator (ESP) at applied voltages from -10 to +10 kV using aerosolized bacteriophages T3 and MS2. For each charging scenario, samples were collected from the effluent air stream and assayed for viable phages using plaque assays and for nucleic acids using quantitative polymerase chain reaction (qPCR) assays. At higher...

The specific π-π interactions between curved and planar structures, which are different from the general π-π interactions between planar arenes, have generated great attention due to their brand-new, unique, and fascinating photoelectric properties. Herein, the curved-planar (C-P) π-π interactions between corannulene, pyrene and coronene have been investigated using the DFT-D method. A series o...

the effects of substituents on the symmetry and the nature of halogen bonds in [n∙∙∙x∙∙∙n]+-type systems are presented for the yc5h4n∙∙∙x∙∙∙nc5h5 (y = no2, cn, h, ch3, och3, oh, nh2, x = cl, br, i) complexes. some structural parameters, energy data and electronic properties were explored with the density functional theory (dft) calculations. in addition, electrostatic potentials were used in es...

introdouction:the styloid process(sp) has the potential for calcification and ossification. the aim of this study was to investigate the prevalence of different patterns of elongation and calcification of the sp. materials and methods: in this cross-sectional study, 400 digital panoramic radiographs taken for routine dental examination in the dental school of shiraz university were evaluated fo...

This study investigates the transferability of aluminum-silicate-based fuel additivation as a primary, fuel-based mitigation measure for inorganic alkali-based particulate matter (PM) emissions during complete combustion wood chips. Therefore, chips are additivated with 0.5 wt% three different types additive kaolin, which differ mainly in their particle size distribution, and one type kaolinite...

BACKGROUND The risk of chronic obstructive pulmonary disease (COPD) is related to Gc protein allele type, such as Gc*1F, Gc*IS, Gc*2. It has been reported that Gc*1F increased COPD risk, while Gc*2 suppressed the risk. Thus, the allele type of Gc protein is an important factor in COPD. These Gc proteins differ in sugar composition at Thr418 or Thr420. In this study, features of the sugar struct...

Initiatives to displace petroleum and climate change mitigation have driven a recent increase in space heating with biomass combustion. However, there is ample evidence that biomass combustion emits significant quantities of health damaging pollutants. We investigated the near-source micro-environmental air quality impact of a biomass-fueled combined heat and power system equipped with an elect...

Airborne transmission of the influenza virus contributes significantly to the spread of this infectious pathogen, particularly over large distances when carried by aerosol droplets with long survival times. Efficient sampling of virus-loaded aerosol in combination with a low limit of detection of the collected virus could enable rapid and early detection of airborne influenza virus at the point...
