nitrate is an anion of major importance particularly in biological areas. excessive amounts in water supplies indicate pollution from sewage or agricultural effluents. the effects of excessive quantities of nitrate in water are well known. in this research structural modification of natural clinoptilolite by isomorphic substitution was performed. isomorphously substituted zeolite was prepared u...

Different instruments are relevant for different marketing objectives (category demand expansion or market share stealing). To help brand managers make informed marketing mix decisions, it is essential that marketing mix models appropriately measure the different effects of marketing instruments. Randomly Utility Maximizing (RUM) discrete choice models that have been applied to this problem mig...

Molecular discovery often involves identification of the best functional groups (substituents) on a scaffold. When multiple substitution sites are present, the number of possible substituent combinations can be very large. This article introduces a strategy for efficiently optimizing the substituent combinations by iterative rounds of compound sampling, substituent reordering to produce the mos...

Having principal typings (for short PT) is an important property of type systems. In simply typed systems, this property guarantees the possibility of a complete and terminating type inference mechanism. It is well-known that the simply typed λ-calculus has this property but recently J.B. Wells has introduced a system-independent definition of PT, which allows to prove that some type systems, e...

Natural selection operating on amino acid substitution at single amino acid sites can be detected by comparing the rates of synonymous (r(S)) and nonsynonymous (r(N)) nucleotide substitution at single codon sites. Amino acid substitutions can be classified as conservative or radical according to whether they retain the properties of the substituted amino acid. Here methods for comparing the rat...

in this study, prodused wheyless cheese was a kind of feta cheese that was considered as a substitution for uf cheese. in this method, by mixing whey protein concentrate (wpc) or milk protein concentrate (mpc) in cream, similar to retentate, which is used in ultrafiltration cheese, was obtained. then, the process was followed similar to production of uf cheese. two experimental samples with the...

In order to expand application of starch and tung oil, oil anhydride modified potato (TOA starch) was prepared in this work. The structural property, degree substitution, pasting properties, rheological properties emulsifying ability the TOA were investigated. Fourier-transform infrared spectroscopy analysis proved formation starch, substitution 0.021 ± 0.001. Compared with natural its gel, had...

Prediction of protein stability upon amino acid substitutions is an important problem in molecular biology and the solving of which would help for designing stable mutants. In this work, we have analyzed the stability of protein mutants using two different datasets of 1396 and 2204 mutants obtained from ProTherm database, respectively for free energy change due to thermal (DeltaDeltaG) and dena...

We discuss coupling from the past techniques (CFTP) for perturbations of interacting particle systems on Z with a finite set of states, within the framework of the graphical construction of the dynamics based on Poisson processes. We first develop general results for what we call CFTP times with ambiguities. These are analogous to classical coupling (from the past) times, except that the coupli...
