inorganic polyphosphates (polyp) are linear polymers of few to several hundred orthophosphate residues, linked by energy-rich phosphoanhydride bonds. four isolates had been screened from soil sample. by maldi-tof analysis, they were identified as bacillius cereus, acinetobacter towneri, b. megaterium and b. cereus. the production of polyp in four isolates was studied in phosphate uptake medium ...

Background and Objectives: Nowadays corn flakes are the most common form of breakfast cereals however, their vitamins are declined during the baking process. In this research, production of fortified corn flakes by Lactobacillus plantarum and L. reuteri, as well as incorporation of oat and malt fiber as prebiotics have been studied. Materials and Methods: Plackett-Burman statistical design was...

with f ∈ L2(Ω), a reaction coefficient τ > 0 and a diffusion coefficient that is piecewise constant on each element and satisfies ε(x) > ε0 > 0. We assume that there exists a constant ρ > 0 such that ε|κ1 6 ρε|κ2 for two elements satisfying ∂κ1 ∩ ∂κ2 6= / 0, i.e. in other words that ε is of bounded variation from one element to the other. The Bubble Stabilized Discontinuous Galerkin (BSDG) was ...

Abstract Lately, nanoemulsions loaded with hydrophobic drugs have been successfully developed to improve the treatment of several global diseases. On this subject, a detailed study crucial role excipients and experimental conditions used for these nanosystems is still required. Thus, aim work was development Benzidazole (Class I, log P = 0.91), Praziquantel II, P = 2.44), Pyrimethamine II/IV, P...

Poly[(R)-3-hydroxyalkanoic acids] [poly(HAs)] are a class of bacterial storage compounds that are synthesized during unbalanced growth by many Gram-negative and Gram-positive bacteria. Poly(HAs) are deposited intracellularly in the form of inclusions bodies (granules) to levels up to 90% of the cellular dry weight (Jendrossek, 2001; Jendrossek et al., 1996; Steinbüchel and Hein, 2001). In the l...

In this Note we prove that in two and three space dimensions, the symmetric and non-symmetric discontinuous Galerkin method for second order elliptic problems is stable when using piecewise linear elements enriched with quadratic bubbles without any penalization of the interelement jumps. The method yields optimal convergence rates in both the broken energy norm and, in the symmetric case, the ...

Radiotherapy efficacy is often limited by normal tissue toxicity. Standard models to estimate Normal Tissue Complication Probability (NTCP), such as Lyman-Kutcher-Burman (LKB), often rely on parameters derived from the dose-volume histograms (DVHs) which consider organs and tissues to be completely homogeneous with equal sub-volume radiation sensitivities. As a result, they neglect any potentia...
