ibuprofen solid dispersions were prepared by the solvent and fusion-solvent methods using polyethylene glycol (peg), polyvinylpyrrolidone (pvp), eudragit rs po, eudragit rl po and hydroxypropylmethylcellulose (hpmc) as carriers to improve physicochemical characteristics of ibuprofen. the prepared solid dispersions were evaluated for the flowability, solubility characteristics and dissolution be...

It is well recognized that the measurements of optical rotatory dispersion of proteins with strong absorption bands are extremely difficult because of the diminishing intensity of the emergent light. Until very recently, these studies were made possible only by improving the light source and also frequently by a wide opening of the slit width on the monochromator at the expense of spectral puri...

The main objective of this study is to propose a methodology to build a parametric linear model of Flexible Multibody Systems for control design. This approach uses a combined Finite Element State Space Approach based on component modes synthesis and double-port approach. The proposed scheme offers the advantage of automatic assembly of substructures, preserving the elastic dynamical behavior o...

Fever: a Clinical Study. By T. J. Maclagan, M.D. London: J. & A. Churchill. 1888. Dr. Maclagan has above all things the pen of a ready writer, and this book forms no exception in respect of quality to his previous publications. It is so pleasant to peruse a book whose grammar is irreproachable, and style attractive. In the space of something over 160 pages, Dr. Maclagan enunciates his theories ...

The aim of this paper is to give some connections between the structure of an abelian finite group and the structure of its subgroup lattice. Let (G, +) be an abelian group. Then the set L(G) of subgroups of G is a modular and complete lattice. Moreover, we suppose that G is finite of order n. If L n is the divisors lattice of n, then the following function is well defined: ord : L(G) −→ L n , ...

In a recent paper, Peláez and Ynduráin evaluate some of the low energy observables of ππ scattering and obtain flat disagreement with our earlier results. The authors work with unsubtracted dispersion relations, so that their results are very sensitive to the poorly known high energy behaviour of the scattering amplitude. They claim that the asymptotic representation we used is incorrect and pr...

We study the q-Cli ord algebras Clq2(N; c ), called FRT{Cli ord algebras, introduced by Faddeev, Reshetikhin and Takhtajan. It is shown that Clq2(N; c ) acts on the q-exterior algebra (O q2 ). Moreover, explicit formulas for the embedding of Uq2(soN ) into Clq2(N; c ) and its relation to the vector and spin representations of Uq2(soN ) are given and proved. MSC 2000: 81R50, 15A66

100-150 ord) Responding to the climate change challenge requires a massive development and diffusion of carbon neutral technologies and, thus, emergence and growth of new socio-technical systems. This paper contributes to an improved understanding of the formative phase of new technological innovation systems (TIS) by outlining a framework for analysing TIS dynamics in terms of structural growt...
