The role of environments with extreme ecological conditions in the reductive evolutionary development processes of animal
Different groups of animals show phenotypic characters, which have been resulted by the reductive phenomena. The examples are the absence of pigmentation; dwindle of eyes in some cave-living animals, and also the absence of scale in some fishes. These characters are often leaded to evolution of new species with special adaptation that is so called "Regressive evolution". The reductive phenomena...
متن کاملSynthesis of Zinc Dimethyldithiocarbamate by Reductive Disulfide Bond Cleavage of Tetramethylthiuram Disulfide in Presence of Zn2+
The zinc(II) complex [Zn2(dmdtc)2(μ-dmdtc)2] has been synthesized directly from thiram ligand, containing a disulfide bond {dmdtc = N,N-dimethyldithiocarbamate; thiram = N,N-tetramethylthiuram disulfide}, and characterized by elemental analysis and spectroscopic methods. Surprisingly thiram, undergoes a reductive disulfide bond scission upon reaction with Zn2+ in methanolic media to give the [Z...
متن کاملComputing Invariants of Reductive Groups in Positive Characteristic
This paper gives an algorithm for computing invariant rings of reductive groups in arbitrary characteristic. Previously, only algorithms for linearly reductive groups and for finite groups have been known. The key step is to find a separating set of invariants.
متن کاملUnramified Representations of Reductive Groups over Finite Rings
Lusztig has given a construction of certain representations of reductive groups over finite local principal ideal rings of characteristic p, extending the construction of Deligne and Lusztig of representations of reductive groups over finite fields. We generalize Lusztig’s results to reductive groups over arbitrary finite local rings. This generalization uses the Greenberg functor and the theor...
متن کاملChern classes of compactifications of reductive groups
In this paper, I construct noncompact analogs of the Chern classes of equivariant vector bundles over complex reductive groups. Then “Chern classes” of the tangent bundle are used to carry over to the case of an arbitrary reductive group some of the well-known results that hold for a complex torus. One of the results of this paper is a formula for the Chern classes of all regular equivariant co...
متن کاملReductive elimination of alkylamines from low-valent, alkylpalladium(II) amido complexes.
A series of three-coordinate norbornylpalladium amido complexes ligated by bulky N-heterocyclic carbene (NHC) ligands were prepared that undergo reductive eliminations to form the alkyl-nitrogen bond of alkylamine products. The rates of reductive elimination reveal that complexes containing more-electron-donating amido groups react faster than those with less-electron-donating amido groups, and...
