A crucial environmental public health risk is air pollution caused by organic contaminants, bio-aerosols, and fine particulate matter (PM2.5–10). multi-purpose photocatalyst filter with photocatalytic nitrogen-doped titanium dioxide (PNT) incorporated into non-woven polymer fibers (NWPF) wide applications focused on in detail this work. Loading of PNT NWPF carried out the simple dip coating met...

Abstract Thin copper films with thickness ∼28 nm deposited on SiO 2 substrate the vacuum electron beam evaporation method and treated by UV-ozone are studied. It was found that a treatment of film causes rapid formation thin ∼3-4 oxide film. XPS analysis showed CuO predominates in this The formed effectively protects against following oxidation. presented is simpler cheaper approach compared to...

the effect of in ovo injection of olive leaf extract as a growth promoter antibiotic was studied on hatchability, day old chick weight, growth rate, feed conversion ratio, mortality and carcass efficiency. three hundred and twenty eggs were divided into 4 groups, and injected on day 18. treatments consisted of: 1- control (no injection). 2- injection of 1 ml of distilled water in air sac (dw), ...

Cervicofacial subcutaneous emphysema is an infrequently reported sequela of dental surgery. It may be caused by the inadvertent introduction of air into the soft tissues during procedures using high-speed, air-driven handpieces or air-water syringes. In this paper, we present a case in which subcutaneous emphysema developed in a middle-aged woman following routine restorative treatment. We revi...
