two  simple  protocols  for  the  synthesis  of  1,  2,  4,  5-  tetrasubstitutedimidazoles  using  nano-spa  as  a  reusable,  eco-  friendly,  inexpensive,  and  efficient  catalyst  are  reported.  short   reaction  times,  high  yields,  scale-up  and  easy  workup  are  the   advantages of these protocols.

The aim of the present study was to investigate the relationship of components of self-compassion with well- being. Research method is correlation and Statiscal population included the male high school students of Yasooj in academic years of 1393-94. The participants of the study were samples who were selected by multistage random sampling method. Scale of self - compassoin (neff, 2003) and wel...

We show how to efficiently project a vector onto the top principal components of a matrix, without explicitly computing these components. Specifically, we introduce an iterative algorithm that provably computes the projection using few calls to any black-box routine for ridge regression. By avoiding explicit principal component analysis (PCA), our algorithm is the first with no runtime dependen...
