Reviewing the accidents and incidents with UAVs, many of these are a consequence of events that were not imagined before starting to use them in a specific setting. Among the known origins, a strong contribution of human factors deficiencies is mentioned. In our industrial context, we propose an engineering methodology focused on human factors, and an application to the design of a ground contr...

Fatigue design of engineering structures is typically based on lifetime calculation using a cumulative damage law. The linear rule by Miner the universal standard for fatigue even though numerous experimental studies have shown its deficiencies and possible non-conservative outcomes. In an effort to overcome these deficiencies, many nonlinear models life prediction been developed since; however...

there are a lot of approximation techniques for structural optimization. among them, four outstanding approximation methods have been selected for trusses optimization. these approaches have been developed or modified by previous ones. based on these schemes, a lot of trusses have been optimized by author's program. this study shows that the abilities of the mentioned methods are not the s...

Weight loss surgery, particularly the Roux-en-Y gastric bypass (REYGB), has become a popular treatment strategy for obesity. Often the only measure of success is the amount of weight lost following surgery. Unfortunately the nutritional adequacy of the postoperative diet has frequently been overlooked, and in the months to years that follow, nutritional deficiencies have become apparent, includ...

Ethylene is a gaseous plant hormone involved in many aspects of plant life, including seed germination, flower senescence, abscission, and fruit ripening (Abeles et al., 1992). It also plays a very important role in the responses of plants to both biotic and abiotic stresses (Abeles et al. The production of ethylene is tightly regulated by internal signals, and usually increases in response to ...

BACKGROUND A significant proportion of homeless people drink alcohol excessively and this can lead to malnutrition and consequent medical problems. The aim of this review was to assess the evidence on the range of nutritional deficiencies in the homeless problem-drinking populations. METHODS We conducted a comprehensive search of nine scientific literature databases and 13 grey literature sou...

in an earthquake country like iran it is of paramount importance that the structural form be sound. the designer must be able to predict satisfactorily the behavior of the structure in the event of a strong ground motion. in order to be able to make a wise choice, he also should know enough about the consequences of the earthquake damage to the structure and economic factors involved. this pipe...

This paper provides a comprehensive review of the current situation regarding micronutrient deficiencies among children and women in Bangladesh. This review also discusses the successes and current challenges of existing intervention programmes. Data from nationally representative and selected small surveys since the 1980s that have reported on the status of at least one micronutrient in childr...
