some lie algebra analogues of schur's theorem and its converses are presented. as a result, it is shown that for a capable lie algebra l we always have dim l=z(l)  2(dim(l2))2. we also give give some examples sup- porting our results.

in order to determine the best form factor formula for loblolly pine (pinus taeda l.) plantations in talesh (western guilan province-iran), a number of 110 trees were selected based on their distribution in diameter classes, from 12 to 34 cm (in a two- cm diameter interval). first, several quantitative factors including diameter at breast height, diameter at 0.65 m of height, and diameter at st...

in the third millennium, we observe rapid changes in technologies and intense complexity in environment. in such an environment, developing competitive advantage necessitates new kind of organizations which are capable of knowledge creation. hence, it is expected that managers to have a deep perception of prerequisites of knowledge management and enhance the organizational performance through i...

Cardiac allograft vasculopathy is thought to be triggered by an alloreactive response to the donor coronary vasculature, resulting in smooth muscle cell proliferation and ultimate occlusion of the donor coronary arteries. To determine whether allogeneic lymphocytes are capable of regulating endothelial-derived smooth muscle cell (SMC) growth factors, human aortic endothelial cells (HAECs) were ...
