Acute respiratory exacerbations have been proposed to contribute to the negative energy balance which causes undernutrition in cystic fibrosis. However, no studies have measured their effect on all components of energy balance. The aim of this study was to measure the effect of an acute respiratory exacerbation on energy balance. Fourteen children (six females, eight males, mean+/-SD age 9.9+/-...

Catalytic converters are used for minimizing the release of pollutants to the atmosphere. It is during the warm-up period that hydrocarbons are seen to be released in appreciable quantities from these converters. In this paper the conversion of a fast oxidizing hydrocarbon propylene is analysed using two numerical methods. The quasi steady state method assumes the accumulation terms to be negli...

Due to the limited resources acquired by sensor, energy consumption is one of main issues that have drawn attention researchers in field wireless sensor networks (WSN). In this paper, we propose a new protocol based on duty cycle method and threshold. The suggested aims balance traffic among all nodes. As result, entire network will be balanced prevent service interruptions portion network. Fur...

The main purpose of this paper was to use a combination of Energy-based design method and whale algorithm (WOA), hereinafter referred to as E-WOA, to optimize steel moment frames and improve the seismic performance. In E-WOA, by properly estimating the seismic input energy and determining the optimal mechanism for the structure, steel frames are designed based on the energy balance method; acco...
