Over the past decade, the number of studies that investigate aerosol–cloud interactions has increased considerably. Although tremendous progress has been made to improve the understanding of basic physical mechanisms of aerosol–cloud interactions and reduce their uncertainties in climate forcing, there is still poor understanding of 1) some of the mechanisms that interact with each other over m...

the main objective of this study is to evaluate the spatial effect on fluctuations of trade based on the spatial panel data econometric method and wavelet smoothing using bilateral trade weighted matrix. the negative spatial dependent are estimated. using data from 34 most-important countries the period of 1980-2010 are investigated through spatial model and maximum likelihood estimation method...

background: the cholinergic system plays an important role in learning and memory. administration of extracts of curcuma longa or its constituent, curcumin, have some roles in cognitive function in animals. the aim of the present study was to investigate the effects of curcumin in preventing spatial performance impairment induced by scopolamine, a cholinergic receptor antagonist, in rats using ...
