in this paper, the effects of input temperature and compression ratio on the net output work and efficiency of the air standard cycles, i.e. atkinson cycle, diesel cycle and otto cycle are analyzed. we assumed that the compression and power processes are adiabatic and reversible and any convective, conductive and radiative heat transfer to cylinder wall during the heat rejection process may be ...

A set of 60 cDNAs were isolated by subtractive hybridization screening of a phage library using radioactively-labeled probes generated from root mRNAs isolated from tobacco (Nicotiana tabacum cv Burley 21) plants before and 3 days after topping. Among the differentially expressed gene products were full-length and partial cDNAs encoding arginine decarboxylase (ADC), ornithine decarboxylase (ODC...

Industrialization of construction makes building operation more environmental friendly and sustainable. This change is necessary as it an industry that demands large consumption water energy, well being responsible for the disposal a high volume waste. However, transformation sector big challenge worldwide. It also known largest proportion material used in multistory buildings, thus its carbon ...

The aim of this work was the evaluation of the catalytic steam reforming of a gaseous fuel obtained by steam biomass gasification to convert topping atmosphere residue (TAR) and CH4 and to produce pure H2 by means of a CO2 sorbent. This experimental work deals with the demonstration of the practical feasibility of such concepts, using a real woodgas obtained from fluidized bed steam gasificatio...

The moisture and dimensional behaviors of a nail-laminated timber (NLT)–concrete slab composed an NLT–plywood composite topping concrete are monitored for 385 days. is developed using as flexural elements such floors. humidity control wood gently introduces significant fluctuations under the ambient relative into slab, in result changes. equilibrium content increases from 6.7% to 15.3% during m...
