We characterize compact composition operators on real Banach spaces of complex-valued bounded Lipschitz functions on metric spaces, not necessarily compact, with Lipschitz involutions and determine their spectra.

Alcoholato Complexes, Cobalt(II) Chlorides Alcoholato complexes of cobalt(II) chloride with the general formula, C0CI2 • x R O H (where R = Me, Et, Pr», Bu», Bu«, Bu* and Bu') have been synthesised by the reactions of anhydrous C0CI2 with an excess of the appropriate alcohols under reflux. Physicochemical studies such as electronic, infra-red spectra, magnetic and conductivity measurements have...

We report on a fully quantum chemical investigation of important structural and environmental effects on the site energies of chlorophyll pigments in green-plant light-harvesting complex II (LHC II). Among the tested factors are technical and structural aspects as well as effects of neighboring residues and exciton couplings in the chlorophyll network. By employing a subsystem time-dependent de...

5-((4-alkoxyphenyl)azo)salicyladehyde, 5-((4-alkoxyphenyl)azo)-n-(npentyl, ndodecyl)-salicyladimine and bis [5-((4-alkoxyphenyl)azo)-n-(npentyl, ndodecyl)-salicyladiminato]copper(ii) [alkoxy=oncnh2n+1; n=3-7] homologues were synthesized and characterized by elemental analyses, mass and ir spectra. all complex homologues are thermally stable. cyclic voltammetric studies indicated that all copper...

In this research thin film heterogeneous cation exchange membrane was prepared by interfacial polymerization of polyacrylic acid-co-iron nickel oxide nanoparticle son PVC based substrate. Spectra analysis confirmed graft polymerization conclusively. The SEM images showed that polymerized layer covers the membranes by simple gel network entanglement. Results exhibited that membrane water content...

The permeability of the preform composite materials used in liquid molding processes such as resin transfer molding and structural reaction injection molding is a complex function of weave pattern and packing characteristics. The development of tools for predicting permeability as a function of these parameters is of great industrial importance. Such capability would speed process design and op...

more than half of all hydrocarbon reservoirs are naturally fractured reservoirs (nfrs), in which production forecasting is a complicated function of fluid flow in a fracture-matrix system. modelling of fluid flow in nfrs is challenging due to formation heterogeneity and anisotropy. stress sensitivity and depletion effect on already-complex reservoir permeability add to the sophistication. horiz...

In this research project, the nitrito nitro isomerization of [Co (NH3)5No2]F2 complex has been studied. Isomerization of this complex in the solid state follows a first order kinetics. The rate of isomerization at different temperatures was determined using a Fourier Transform Lnfrared Spectrophotometer. ? and ? are calculated at 298 K. The infrared, visible and ultraviolet spectra of th...
