The article substantiates the conceptual principles of reducing food loss and waste from standpoint ensuring security environmental sustainability. approaches to interpretation concepts are summarized, similarities differences between them, as well reasons for their formation connection noted. main causes losses waste, which caused by human, technical-technological, natural-climatic, economic, ...

purpose weight loss in wrestling has been found to be an interesting issue for researchers. in this regard, complications of weight loss in wrestlers before the competitions and their weight gain in course of competitions have been debated in previous studies. the objective of this study was to investigate the extent of weight gain and to estimate the percentage of body fat in participants in t...

The portable generators are the main means of compensating the shortage of national electricity power as in Iraq. However, their noise causes a huge disturbance, uncomforting and loss of concentration of the nearby resident. This problem requires a solution because most shops and residential houses use generators. Covering method is a simple and relatively low cost one for reduction of generato...

a three-year field experiment was conducted under conditions of luvic chernozem soil. diversified nitrogen fertilization with 0, 60, 120, and 180 kg n ha-1, and microbial preparations improving soil properties were applied to potatoes, cv. ‘satina’, cultivation. n–no3 concentration in the soil profile (0–0.9 m) in autumn after potato harvesting fluctuated from 28 kg n ha-1 in the n0 treatment t...

Background: The burden of obesity and diet-related chronic diseases is increasing in Iran, and prevention and treatment strategies are needed to address this problem. The aim of this study was to determine the outcome, cost, safety and cost-consequence of non-invasive weight loss interventions in Iran.   Methods: We performed a systematic review to compare non-invasive interventions (cr...

Degradation is a common problem for polymer matrix composites (PMCs) under low thermal cycling conditions. This paper investigates the effects of low thermal cycling on total mass loss (TML) and surface degradation of PMCs. Unnotched and open-hole specimens were weighed before and after low thermal cycling. The total mass loss and surface degradation of the specimens were studied over 250 cycle...

polyanionic cellulose polymer is used as an additive in drilling mud in order to decrease water loss and mudcake- thickness. in this study effect of bulk and nanosize polyanionic cellulose on water loss and mud-cakethickness in mud drilling is investigated. polyanionic cellulose nanoparticles are made by using of ball milling. size of nanoparticles is measured by particle size analyzer. polyani...
