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...
