The aim this review identify how infects man, preventive approach treatment possibility with ivermectin drug. possible main source transmission thought be close c...

The adoption of phase change materials (PCMs) is a promising solution for the improvement building energy performances and indoor comfort, integration geopolymer concrete (GPC) allows recycling reducing demand raw in production. Both contribute to carbon dioxide emission lifecycle. In this frame, paper proposes complete numerical approach selecting optimal wall package made GPC PCMs Mediterrane...

introdouction: the mapping of ghost images of the maxilla and the nasal cavity, which are complex structures, is very important. the position of objects that create a ghost image can differ when using various devices. the purpose of this investigation was to study the mapping of ghost images of the maxilla and the nasal cavity using a cranex d digital panoramic machine. materials and methods: t...

a 79 year old fanner referred to a dental clinic because of toothache for one week. after extraction of a painful tooth, three larvae, 1.5 cm in length emerged from the dental cavity. morphological study of the larvae proved them as w. magnifica. this is the first report of dental cavity myiasis from iran.

This study investigates the ventilated cavities around a surface-piercing hydrofoil, aiming to extend previous studies by an in-depth understanding of vaporous cavity behaviors and flow-regime transition at high Froude numbers. An experiment is carried out in constrained-launching water tank with vertically cantilevered hydrofoil piercing still surface. The recorded using high-speed photography...

Humans produce exhaled breath particles (EBPs) during various breath activities, such as normal breathing, coughing, talking, and sneezing. Airborne transmission risk exists when EBPs have attached pathogens. Until recently, few investigations had evaluated the size and concentration distributions of EBPs from mechanically ventilated patients with different ventilation mode settings. This study...

BACKGROUND Eye care is an essential component in the management of critically ill patients. Standardized eye care can prevent corneal complications in ventilated patients. OBJECTIVE This study was designed to compare old and new practices of corneal care for reduction in corneal complications in ventilated patients. METHODS This study was done in three phases each of six month duration. Pha...
