This paper uses the super efficiency SBM model based on unexpected output to calculate industrial carbon emission of 30 provinces in China from 2005 2019, and spatial autocorrelation other methods conduct an empirical analysis dynamic evolution process temporal differences efficiency. The results show that China's is still low stage, with average value 0.34. In study period, although overall tr...

We present the first evidence of the decay mode Bs → φφ and a measurement of partial width and direct CP asymmetry for the B + → φK + decay using 180 pb −1 of data collected by the CDF II experiment at the Fermilab Tevatron collider. We measure: BR(Bs → φφ) = (1.4 ± 0.6(stat.) ± 0.2(syst.) ± 0.5(BR)) · 10 −5 , where the last error is due to the uncertainty on the Bs → J/ψφ branching ratio used ...

allergy to prosopis juliflora (mesquite) pollen is one of the common causes of respiratory allergy in tropical countries. mesquite is widely used as street trees in towns and ornamental shade trees in parks and gardens throughout arid and semiarid regions of iran. the inhalation of mesquite pollen and several species of amaranthus/chenopodiaceae family is the most important cause of allergic re...

abstractin the last step of desolvation method for preparation of albumin nanoparticles, glutaraldehyde (ga) is added to stabilize the newly formed nanoparticles. due to undesirable effects of ga, the objective of this study was to evaluate alternative methods of crosslinking including ultraviolet (uv) irradiation, adding of glucose and combination of both methods. the nanoparticles were prepar...

in this study, a cross-docking system is designed at strategic and tactical levels. for making the strategic decisions, a multi-objective nonlinear location allocation model for cross-docks is presented based on a distri-bution location allocation model by andreas klose and andreas drexl. the model is further developed to in-clude the whole supply chain members and the objective functions are w...
