The first step in dealing with the behavior of an engine on NG mode is the installation of a suitable gas fueling system on the engine. Two generations of gas fueling systems which were studied and installed on research engine were Mixer type and Sequential system type. The results, including performance, emissions and fuel consumption, were recorded and analyzed. The results showed that the...

the infant feeding practices and the effects of factors such as mother’s educational level, primary health care, and family income on these practices in 531 households with 930 children 6-60 months of age were studied in rural areas of sirjan (kerman province), iran. the findings indicate that the majority of mothers (85%) breastfeed their infants and 86% of babies are fed the colostrums. the a...

there is a relationship between infant feeding method and maternal postpartum depression (ppd). this study was carried out in an iranian population to compare the prevalence of ppd symptoms between breast feeding and non-breast feeding mothers for first time.four health centers in ahvas were selected by random sampling in 2009. at first 78 non-breast feeding mothers at two months postpartum wer...

In this paper, two-stage and purely sequential estimation procedures are considered to construct fixed-width confidence intervals for the reliability parameter under the stress-strength model when the stress and strength are independent exponential random variables with different scale parameters. The exact distribution of the stopping rule under the purely sequential procedure is approximated ...

BACKGROUND Pseudomonas putida KT2440 is able to synthesize large amounts of medium-chain-length polyhydroxyalkanoates (mcl-PHAs). To reduce the substrate cost, which represents nearly 50% of the total PHA production cost, xylose, a hemicellulose derivate, was tested as the growth carbon source in an engineered P. putida KT2440 strain. RESULTS The genes encoding xylose isomerase (XylA) and xyl...

Abstract Background Efficient utilization of all available carbons from lignocellulosic biomass is critical for economic efficiency a bioconversion process to produce renewable bioproducts. However, the metabolic responses that enable Pseudomonas putida utilize mixed carbon sources generate reducing power and polyhydroxyalkanoate (PHA) remain unclear. Previous research has mainly focused on dif...

The behavior of individually kept PIC Camboroughsows was compared when they were housed in three systems: pasture, soil or gestation crates. All sows were fed 2.0 kg of fortified, sorghum-soybean diet each day. Crated sows were divided into two groups: those fed meal and those fed pellets. As is common among sows on pasture and soil, outdoor sows were fed pellets. Eight sows per treatment were ...
