The yjbEFGH operon is implicated in the production of an exopolysaccharide of an unknown function and is induced by osmotic stress and negatively regulated by the general stress response sigma factor RpoS. Despite the obvious importance of RpoS, negative selection for rpoS has been reported to take place in starved cultures, suggesting an adaptive occurrence allowing the overexpression of RpoD-...

weichang’an (wca) pill, a traditional chinese patent medicine consisting of ten chinese medicinal herbs, has been used to treat irritable bowel syndrome and functional dyspepsia for several decades. in this study, twelve bioactive constituents in the methanol extract of wca were accurately identified since ms/ms fragmentation behavior of the references and the standards by using hplc-dad-esi-ms...

This paper presents general methodologies for comparing distributed algorithms, which are exemplified by clustering algorithms in sensor networks. Significant metrics for evaluating the algorithms are introduced including aspects of a structural, analytical and simulative comparison. Finally a short, exemplary comparison of two clustering algorithms HEED and WCA is made.

Weichang’an (WCA) pill, a traditional Chinese patent medicine consisting of ten Chinese medicinal herbs, has been used to treat irritable bowel syndrome and functional dyspepsia for several decades. In this study, twelve bioactive constituents in the methanol extract of WCA were accurately identified since MS/MS fragmentation behavior of the references and the standards by using HPLC-DAD-ESI-MS...

This paper presents an efficient control allocation (CA) strategy which significantly improves the flight performance of a planar hexacopter. maps desired vector v = [ T, L,M,N ]⟙ composed thrust and torques in roll, pitch, yaw axis, respectively, to propellers’ speed. shows that CA based on cl...

Hydrophobic coatings based on dodecyl acrylate (DOCA) and perfluorodecyl (PFDA) have been generated via “postdischarge” atmospheric pressure plasma deposition. These exhibit a water contact angle (WCA) of around 125° but are accompanied by poor mechanical strength. To improve this property, two different types chemical crosslinkers, that is, hexanediol methacrylate (HDMA) diacrylate (HDA), inco...

To evaluate the effect of thermocycling on water contact angle (WCA), surface roughness (SR), and microhardness (MH) different CAD-CAM PMMA denture base materials after treatments (conventional laboratory polishing, polishing kit, or sealant). Disk-shaped specimens (10 × 2 mm) 3 PMMAs, AvaDent (AV); Merz M-PM (M-PM); Polident (Poli), a conventional heat-polymerized (Vynacron) (CV) (n=21) were d...

Maximum Power Point (MPP) tracker has an important role in the performance of fuel cell (FC) systems improvement. Tow parameters which have effect on the Fuel cell output power are temperature and membrane water. So contents make the MPP change by with variations in each parameter. In this paper, a new maximum power point tracking (MPPT) method for Proton Exchange Membrane (PEM) fuel cell is pr...

The purpose of this study is to clarify the individual differences in consciousness students participating a wooden craftsmanship activity (WCA) program. Based on conducted Ono, village located low uplands and mountainous region Miyama Ward, Nantan City, Kyoto Prefecture, we determined three principal components participants: “Awareness contribution local region,” forest conservation,” craftsma...
