A polynomial expansion is proposed as a new way to discretize the Griffin-Wheeler-Hartree-Fock equations of the Generator Coordinate Hartree-Fock method. The implementation of the polynomial expansion in the Generator Coordinate Hartree-Fock method discretizes the Griffin-Wheeler-Hartree-Fock equations through a numerical mesh which is not equally spaced. This procedure makes the optimization of Gaussian exponents in the Generator Coordinate Hartree-Fock method more flexible and more efficient. The results obtained with the polynomial expansion for atomic Hartree-Fock energies show this technique is very powerful when employed in the design of compact and high accurate Gaussian basis sets used in ab initio non-relativistic (Hartree-Fock) and relativistic (Dirac-Fock) calculations. 相似文献

Mono- and binuclear complexes of 2-(2-pyridyl)benzimidazole and its 1-alkyl-substituted derivatives with zinc dichloride were synthesized and structurally characterized. In terms of the competitive coordination problem, it was shown that pyridylbenzimidazole is an N,N-chelating ligand. The binuclear complex is formed through a dichloride bridge. 相似文献

COMPONENT ALLEE EFFECTS AND STAGE‐SPECIFIC PREDATION: A BRIEF INSIGHT INTO CONSERVATION AND BIOLOGICAL CONTROL ISSUES 下载免费PDF全文
In this paper, we propose a two‐stage structured population model subject to component Allee effects in fecundity and maturation, and with two disturbances (predation only and harvest and predation) acting on both stages. It is shown that this combination leads to a demographic Allee effect—a characteristic that could be exploited in pest biological control, but on the other hand, it represents a bane in conservation biology. The analysis is performed for disturbances with functional responses type 2 and 3, and the models show that they yield qualitatively similar results. This characteristic is discussed from the species conservation and biological control point of view, together with possible extensions of this work. 相似文献

N-Alkylsalicylideneimines and their complexes with 3d metals were obtained by chemical (from metal salts) and electrochemical methods (from metals in the zero oxidation state). The compounds obtained were characterized by IR and 1H NMR spectroscopy and X-ray diffraction analysis. According to crystallographic data, nickel bis(chelate) exists in the trans-planar configuration. A friction test revealed that the tribotechnical characteristics of lubricating formulations are substantially enhanced in the presence of N-alkylsalicylideneiminates. 相似文献

Supramolecular coordination ensembles with d-metal ions directly incorporated into their structures are the subject of the present review. Diversity of such structures
considerably exceeds that of purely organic supramolecules due to inclusion of additional polyvalent metal atoms (totally
sixty) with diverse coordination geometry. Such metal-containing constructions are generated by self-assembling and (or) by
templating, as 2D and 3D geometric figures (polygons and polyhedra) and “furniture” constructions (ladders, racks, grids)
together with helicates, interwoven species and metallodendrimers as combinations of 1D coordination compounds. Besides, is
presented a numerous of coordination polymers and supramolecular crystal lattices as infinite structures. 相似文献

The Schiff's bases 2-alkyl-4-oxo-3,4-dihydro-2H-1,2-benzothiazine 1,1-dioxides have been synthesized for the first time, their
structures in solution and in the crystalline state and their ability to form complexes have been investigated. The unusual
condensation reaction of 1,2-benzothiazine 1,1-dioxide with ethyl orthoformate and 4-aminoantipyrine has been observed. 相似文献
