(1) Background: When a fire breaks out, combustibles are burned and toxic substances such as carbon monoxide (CO), polycyclic aromatic hydrocarbons (PAH), benzene, hydrogen cyanide produced. The purpose of this study is to evaluate the air quality inside self-contained breathing apparatus (SCBA) by comparing it that in environment where SCBA charger installed. (2) Methods: design was simulation...

Columns at the ground floor and parking garages that could be hit by a car pose significant risk to structural stability of building superstructures. Generally, these columns are not built sustain lateral impact force generated car–column collision. In this study, performance axially loaded retrofitted reinforced concrete (RC) against is evaluated using finite element (FE) simulation. The FE mo...

The traditional concept of the primary, secondary, tertiary and later quaternary economy is based on several structurally divided related tasks processes in processing raw materials earth resources. Gradually, a new functioning was created, called “circular economy” or economy”. Its basis transformation linear economic managing use to create sustainable growth model. circular transforms activit...

background and objectives: the aim of our study was to characterize gizzard lactobacillus fermentum-group strains on the basis of their phenotypic profiles regarding characteristics of lactobacilli. in addition, their in vitro potential probiotic properties were evaluated. materials and methods: the lactic acid bacteria were isolated and identified from gizzard contents of algerian local poultr...

one of the important issues in hydraulic engineering is inspection of local scour depth around bridge pier. using piles is one of the ways for confronting local scour and erosion. in this study, the experiments were conducted in an 8m long, 0.5m deep and 0.25m wide flume. and the effectof using piles and number of them observed on the amount of scour in three different frude numbers. the shape ...

a nulliparous non-descript mare was presented with a complaint of dystocia. the mare was recumbent and physical examination revealed that the animal was in shock. there was no straining and foetal forelimbs were visible outside the vulva. the foetus was dead as there was no pedal reflex. vaginal examination revealed anterior presentation with dorso-sacral position and rigid lateral head deviati...

research topics dealing with the application of the markal model have been quite common in the last 20+ years. every new paper has added new insight into the potential of using such a model for a variety of purposes. not only global but also local applications have shown both limits and benefits when dealing with manifold energy-environmental-resources optimal management. the aim of this wo...

most of the ingested foreign bodies pass uneventfully through the gastrointestinal tract. however, long and rigid foreign bodies are associated with an increased risk of gastrointestinal impaction, perforation, and bleeding. spontaneous passage of a toothbrush has not been reported till date and the technique of its removal is a curiosity for surgeons. endoscopy is a recommended technique for t...
