Micro-Ikebana by Biomimetic Crystallization of Alkaline Earth Carbonates∗
Biomineralization is the process of forming hard exoor endoskeltons by biological organisms. The physical properties and the morphology of the composite material that is formed depends on the mode of crystal-growth, which depends on the diffusion of the constituents (metal cations, their anions, and additives). We chose a model system, strontium carbonate / silica, because the precipitation of ...
متن کاملRapid hydrolysis of model phosphate diesters by alkaline-earth cations in aqueous DMSO: speciation and kinetics.
Kinetics of the cleavage of two phosphate diesters, bis(4-nitrophenyl) phosphate and 2-hydroxypropyl 4-nitrophenyl phosphate and a triester, 4-nitrophenyl diphenyl phosphate, in the presence of Mg(II), Ca(II) and Sr(II) were studied in 90% vol. DMSO at 37 degrees C. The alkaline hydrolysis of the triester was inhibited by all cations, but with both phosphodiesters strong catalytic effects were ...
متن کاملDegenerate kernel approximation method for solving Hammerstein system of Fredholm integral equations of the second kind
Degenerate kernel approximation method is generalized to solve Hammerstein system of Fredholm integral equations of the second kind. This method approximates the system of integral equations by constructing degenerate kernel approximations and then the problem is reduced to the solution of a system of algebraic equations. Convergence analysis is investigated and on some test problems, the propo...
متن کاملIntegral approximation by kernel smoothing
where f̂ is the classical kernel estimator of the density of X1. This result is striking because it speeds up traditional rates, in root n, derived from the central limit theorem when f̂ = f . Although this paper highlights some applications, we mainly address theoretical issues related to the later result. We derive upper bounds for the rate of convergence in probability. These bounds depend on ...
متن کاملkinetics of alkaline protease production by streptomyces griseoflavus ptcc1130
background and objectives: proteases are a group of enzymes that catalyze the degradation of proteins resulting in the pro- duction of their amino acid constituents. they are the most important group of industrial enzymes which account for about 60% of total enzymes in the market and produced mainly by microorganisms. the attempts were made to study the kinetic parameters of protease produced b...
