few novel cobalt(ii) and copper(ii) complexes [m(fmp)3]cl2, [m(fmp)(bpy)2]cl2,[m(fmp)(phen)2]cl2 and [m(fmp)(phen)(bpy)]cl2 (fmp = 3-furan-2-ylmethylene-pentane-2,4-dione, phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) have been synthesized andcharacterized by elemental analyses, molar conductance, magnetic susceptibility measurements,ir, electronic, epr, mass spectra and cyclic voltam...
glipizide has been found to form inclusion complexes with β-cyclodextrin (β-cd) in solution and in solid state. the present study was undertaken to determine a suitable method for scaling up glipizide-β-cd inclusion complex formation and to evaluate the effect of some parameters on the efficiency of complexation. the solid inclusion complexes of glipizide and β-cd were prepared at a molar ratio...
SCFG-based statistical MT models have proven effective for modelling syntactic aspects of translation, but still suffer problems of overgeneration. The production of German verbal complexes is particularly challenging since highly discontiguous constructions must be formed consistently, often from multiple independent rules. We extend a strong SCFG-based string-to-tree model to incorporate a ri...
Fermi coordinates are the natural generalization of inertial Cartesian coordinates to accelerated systems and gravitational fields. We study the motion of ultrarelativistic particles and light rays in Fermi coordinates and investigate inertial and tidal effects beyond the critical speed c/ √ 2. In particular, we discuss the blackhole tidal acceleration mechanism for ultrarelativistic particles ...
plane and mulberry trees play a crucial role in purifying the polluted air in tehran as a majorcity. in this research, 13 main districts of tehran city were chosen as study area. 20 completely healthy planeand mulberry species were selected in similar ecological conditions and age range. the uptake of cd and pbwas determined using spectrophotometry, whereas the chlorophyll content was measured ...
Let G be a finitely generated group. Two simplicial G-trees are said to be in the same deformation space if they have the same elliptic subgroups (if H fixes a point in one tree, it also does in the other). Examples include Culler-Vogtmann’s outer space, and spaces of JSJ decompositions. We discuss what features are common to trees in a given deformation space, how to pass from one tree to all ...
We generalize the concept of a cycle from graphs to simplicial complexes. We show that a simplicial cycle is either a sequence of facets connected in the shape of a circle, or is a cone over such a structure. We show that a simplicial tree is a connected cycle-free simplicial complex, and use this characterization to produce an algorithm that checks in polynomial time whether a simplicial compl...
during the islamic period of iran except for public complexes including buildings as bazaar, reservoir, caravansary, etc. there were burial complexes that occupy a special place in the architecture of the epoch. these complexes were first built as the burial ground of a famous political or religious figure and along the time other buildings such as mosque, madreseh (school), monastery, caravans...
