value firstly. Computation efficiency will decrease. Abstract⎯Real-coded genetic algorithm (RGA) usually meets the demand of consecutive space problem. However, compared with simple genetic algorithm (SGA), RGA also has the inherent disadvantages such as prematurity and slow convergence when the solution is close to the optimum solution. This paper presents an improved real-coded genetic algori...

A promoterless gene for the Shiga toxin 1 B subunit (stxB1) has been placed under transcriptional control of the Vibrio cholerae heat shock gene htpG. A chromosomal enterohemorrhagic Escherichia coli fragment containing eaeA and 400 bp of upstream DNA was added to the construct, downstream of stxB1; no transcription terminators were located between the two genes. The plasmid construct was confi...

Recently, a link has been suggested between volcanic deposition of SO4 and the suppression of CH4 emissions in northern peatlands (Gauci et al., 2008). This link stems from the widely accepted idea that acid rain SO4 additions to peatlands can cause a shift in microbial communities as SO4 reducing bacteria out-compete methanogens for substrates, which results in a suppression of CH4 emission. H...

Peatlands are one of the contributors to greenhouse gas emissions because it is estimated that carbon stock stored in them around 528 Giga tons (Gt) or equivalent 75% total (C) atmosphere, so if peat oxidized will cause be released into air. The conversion forest land agricultural can causes, including activity making drainage channels. construction channels causes a decrease water table volume...

Abstract. Fast-response infrared gas analyzers (IRGAs) have been widely used over 3 decades in many ecosystems for long-term monitoring of water vapor fluxes the surface layer atmosphere. While some early IRGA sensors are still these national and/or regional eco-flux networks, optically improved newly employed same networks. The purpose this study was to evaluate performance density and flux da...
