BACKGROUND Acute illness is common in childhood, and it is difficult for healthcare professionals to distinguish seriously ill children from the vast majority with minor or self-limiting illnesses. Safety netting provides parents with advice on when and where to return if their child deteriorates, and it is widely recommended that parents of acutely sick young children should be given safety ne...
Background and aims: Aerodrome surface safety and in particular safety of flight environment around them are acknowledged globally as one of aviation's greatest challenges. Aeronautical industries development within recent decays and employment of innovated technologies and procedures, encountered with multiple risk that threating the aviation safety. The main purpose of this resear...
Background and Objectives Considering the role of human resources in every organization, it is very important to address issues that lead to the reduction of occupational injuries in the workplace, it is clear that preventing the occurrence of job burnout in improving people's mental health. It plays an important role. One of the topics that can be useful in reducing job burnout is the applic...
The authors developed, tested, and replicated a model in which safety-specific transformational leadership predicted occupational injuries in 2 separate studies. Data from 174 restaurant workers (M age = 26.75 years, range = 15-64) were analyzed using structural equation modeling (LISREL 8; K. G. Jöreskog & D. Sörbom, 1993) and provided strong support for a model whereby safety-specific transfo...
after test and review results and analysis of farm data, the following results were obtained. the review examined farms was done and the results obtained in this study was to determine the effectiveness of vaccines hatchpak avinew (frozen) and hatchpak ib h120 with spray in broilers a day in factories incubation and at least,they can be as vaccines avinew and bioral h120 ability to create saf...
The high vulnerability of the cultural buildings due to seismic actions urged researchers to retrofit them using reversible and compatible techniques. The application of fiber reinforced polymer (FRP) for enhancing the structural behavior of masonry buildings, under seismic actions, has been studied by many researchers. The near-surface mounting (NSM) technique is a relatively new retrofitting ...
Background The safety and efficacy of Monomeric Carbamylated Allergoid in injections have been previously reported in adult patients. The aim of this case-series was to explore its safety in a paediatric populations. Monomeric Carbamylated Allergoids are chemically modified extracts characterized by hypoallergenic activity due to allergen lysines substitution and preserved structural conformati...
Recently, analysis and designing of the structures based on the Reliability theory have been the center of attention. Reason of this attention is the existence of the natural and random structural parameters such as the material specification, external loads, geometric dimensions etc. By means of the Reliability theory, uncertainties resulted from the statistical nature of the structural parame...
The most common approach to assess the safety of a bridge is load rating. However, this approach cannot quantify the bridge safety in probabilistic terms or fully quantify the structural risk to the bridge. Reliability methods have become an increasingly popular and gradually accepted approach to assess the safety of structures. These methods account for the randomness and correlation of all re...
A review of the current situation and development of fire safety design for steel structures in China is given in this paper. Several codes and specifications used for fire safety design in China are introduced, and the present design methods are summarized. Then some research achievements on the behavior of steel structures at elevated temperature are presented. The achievements include materi...
