using uv-vis spectrophotometric method the interaction of water soluble phthalocyanine, cobalt(ιι) 4,4′,4′′,4′′′- tetrasulfophthalocyanine(cotspc), with bovine serum albumin (bsa) to determine the formation constant and related thermodynamic functions. the measurements were considered in 1mm sodium phosphate buffer, ph 7.0 and at 5 different temperatures 20, 25, 30, 35 and 40ºc. the results sho...

the complex formed as a consequence of the interaction between the electron-acceptor p-chloranilic acid and an electron donor tamoxifen citrate was employed in the assay of the drug in pure powder and tablets. chloranilic acid was found to form a charge-transfer complex in a 1:1 stoichiometric ratio, with tamoxifen citrate. the wavelength of maximum absorption for the complex was found to be 55...

We review some known results and open problems related to the growth of groups. For a nitely generated group ?; given whenever necessary together with a nite generating set, we discuss the notions of (A) uniformly exponential growth, (B) growth tightness, (C) regularity of growth series, (D) classical growth series (with respect to word lengths), (E) growth series with respect to weights, (F) c...

If M = Z, and G is a finite (nonabelian) group, then G is a compact group; a multiplicative cellular automaton (MCA) is a continuous transformation F : G − ←⊃ which commutes with all shift maps, and where nearby coordinates are combined together using the multiplication operator of G. We provide equivalent conditions for MCA to be group endomorphisms of G, and show how MCA on G inherit a natura...

We indicate some formulas connecting Ricci flow and Perelman entropy to Fisher information, differential entropy, and the quantum potential. 1. FORMULAS INVOLVING RICCI FLOW Certain aspects of Perelman’s work on the Poincaré conjecture have applications in physics and we want to suggest a few formulas in this direction; a fuller exposition will appear in a longer paper [11] and in a book in pre...

Using UV-Vis spectrophotometric method the interaction of water soluble phthalocyanine, Cobalt(ΙΙ) 4,4′,4′′,4′′′- tetrasulfophthalocyanine(CoTSPc), with bovine serum albumin (BSA) to determine the formation constant and related thermodynamic functions. The measurements were considered in 1mM sodium phosphate buffer, pH 7.0 and at 5 different temperatures 20, 25, 30, 35 and 40ºC. The results sho...

   In this study, cadmium sulfide nanoparticles (CdS NPs) were prepared, characterized and used as a new adsorbent for simultaneous removal of Pb(II) and Cu(II) ions from aqueous solutions. Using a batch adsorption method, the effects of solution pH, contact time, adsorbent dose, and temperature were studied and optimized. Removal efficiencies, higher than 98% were obtained for both the met...

In this paper, we introduce a new entropy-like invariant, named Hausdorff metric entropy, for finitely generated semigroups acting on compact metric spaces from a set-valued view and study its properties. We establish the relation between Hausdorff metric entropy and topological entropy of a semigroup defined by Bis. Some examples with positive or zero Hausdorff metric entropy are given. Moreov...

In this paper, we show that in order to obtain the Tsallis entropy rate for stochastic processes, we can use the limit of conditional entropy, as it was done for the case of Shannon and Renyi entropy rates. Using that we can obtain Tsallis entropy rate for stationary Gaussian processes. Finally, we derive the relation between Renyi, Shannon and Tsallis entropy rates for stationary Gaussian proc...
