Ecological and environmental education is of special importance in dealing with solving current global problems. This not only important, but also very relevant at all stages a person's age. Properly laid foundations pre-school can help the emerging personality basics critical thinking, promote their creativity, quality relations others. An ecological awareness training "Green Lesson" took plac...

background: with increasing age, some changes appeared in specifications of vessels which including dimensions and elasticity in their. the changes in parameters such as resistance, inertance and compliance vessels appear and eventually changes in the environmental pulse releases are in circulation. these changes clearly appear in specification of photoplethysmogram particularly in the size and...

A bstract In this paper, we explore the open string amplitude’s dual role as a space-time S-matrix and 2D holomorphic CFT correlation function. We pursue correspondence in two directions. First, beginning with general disk integrand dressed Koba-Nielsen factor, demonstrate that exchange symmetry for factorization residue of amplitude forces to be expandable on SL(2,R) conformal blocks. Furtherm...

in laboratory experiments the toxicity of acetone was investigated against four species of stored-product insects. in empty-space trials, estimates of the lethal concentrations of acetone (lc, 72-h exposure) for 50% mortality against adults of the lesser grain borer, rhizopertha dominica (f.), red flour beetle, tribolium castaneum (herbst), rice weevil, si-tophilus oryzae (l.) and eggs of the a...

directional simulation, among techniques for reliability analysis of engineering structures, is well known. in this context, directional simulation in load space, because of the considerable advantages of lower dimension of working space, is of considerable interest. as is expected due to structural resistance variability, the location of the relevant limit state(s) is no longer constant and mu...
