We consider a piecewise continuous, piecewise monotone interval map and a weight of bounded variation, constant on homtervals and continuous at periodic points of the map. With these data we associate a sequence of weighted Milnor-Thurston kneading matrices, converging to a countable matrix with coeecients analytic functions. We show that the determinants of these matrices converge to the inver...

In an earlier paper 1] two of us studied generalized transfer operators M associated to maps of intervals of R. In particular the analyticity of a sharp determinant Det # (1?zM) was analyzed on the basis of spectral properties of M and by relating Det # (1 ? zM) to the determinant of 1 + D(z) for a suitable kneading operator D(z). It is a natural idea to try to replace monotone maps of interval...

In this paper we construct a correspondence between the parameter spaces of two families of one-dimensional dynamical systems, the α-continued fraction transformations Tα and unimodal maps. This correspondence identifies bifurcation parameters in the two families, and allows one to transfer topological and metric properties from one setting to the other. As an application, we recover results ab...

Ochratoxin A (OTA) – secondary metabolite of fungi from genera Aspergillus and Penicillium may mainly contaminate cereal-based food. Thermal processing (including baking) reduce the levels OTA, but also produce racemic mixtures with 2′R-ochratoxin (2′R-OTA) isomer. In this study, stability OTA during rye bread production processes pizza wheat base dough kneading, fermentation, was investigated....

Several attempts have been made to improve the solubility of water insoluble drugs. Over the years, inclusion complexation of drugs with β-cyclodextrin has emerged as a viable attempt to improve the dissolution of water insoluble drugs. The aim of the present work was to improve the dissolution rate of lovastatin, a water insoluble drug, by inclusion complexation with β-cyclodextrin. The stoich...

The present research work was focussed on the preparation as well as the evaluation of Aceclofenac solid dispersions for analgesic, anti-inflammatory and immunosuppressant activities. Solid dispersions were formulated using cros-carmellose sodium as polymer in different ratios. The solid dispersions were prepared using physical mixture, solvent evaporation and kneading techniques. The solid dis...

The objective of this work was to improve aqueous solubility of poorly water soluble drugs by a modified porous starch as solid dispersion carrier. The yield of the porous starch was found to be 80%. The flow property of the prepared porous starch was found to be good, with good compressibility index. The particle size of the prepared porous starch were found to be in the range of 53–130μ. Ther...

The terminal root branch orders composed mainly of primarily-developed tissues are increasingly recognized as an ephemeral module specialized for resource absorption. This root module is crucial in driving a range of ecosystem processes such as belowground productivity, carbon and nutrient cycling. Traditionally, acquisition of the ephemeral root module is achieved by separating these primarily...

The competition between thermal fluctuations and potential forces governs the stability of matter in equilibrium, particular proliferation annihilation topological defects. However, driving out equilibrium allows for a new class that are neither attractive nor repulsive, but rather transverse. possibility activating transverse raises question how they affect basic principles material self-organ...
