Cephalexin is an important antibiotic. It is very significant to determine an appropriate method for the extraction of this valuable antibiotic for industrial applications. Aiming at developing an efficient method for the extraction of cephalexin, the partitioning of cephalexin has been evaluated in aqueous two-phase system, including cholinium chloride and potassium phosphate. The effect of th...

the aim of this study was to evaluate the effects of mentha longofolia plant (mlp) and its essential oils (mle) on ruminal fermentation and protozoa population in goat. the mlp at six levels 0, 25, 35, 55, 75 and 100 mg/30 ml, and the essential oil at six levels 0, 1700,3000,6700,8300 and 10000 mg/l plus monensin (as positive control, 50 mg and dissolved in ethanol) added to rumen fluid respect...

We consider the problem of estimating the partition function of the two-dimensional ferromagnetic Ising and Potts models in an external magnetic field. The estimation is done via importance sampling in the dual of the Forney factor graph representing the models. We present importance sampling schemes that can efficiently compute an estimate of the partition function in a wide range of model par...

A tree-partition of a graph G is a proper partition of its vertex set into ‘bags’, such that identifying the vertices in each bag produces a forest. The treepartition-width of G is the minimum number of vertices in a bag in a tree-partition of G. An anonymous referee of the paper by Ding and Oporowski [J. Graph Theory, 1995] proved that every graph with tree-width k ≥ 3 and maximum degree ∆ ≥ 1...

We propose an importance sampling scheme to estimate the partition function of the two-dimensional ferromagnetic Ising model and the two-dimensional ferromagnetic q-state Potts model, both in the presence of an external magnetic field. The proposed scheme operates on the dual Forney factor graph and is capable of efficiently computing an estimate of the partition function under a wide range of ...

the partition coefficients (p-values) of certain new potential, stereoselective, reversible, long-acting local anesthetics have been determined in an n-octanol/ phosphate buffer system. these are derivatives of 2-phenoxyethyldialkylamine hydrochloride, and almost all of them are readily soluble in water. their aqueous solutions have shown different absorption maxima, and these have been used qu...

Statistics of distinguishable particles has become relevant in systems of colloidal particles and in the context of applications of statistical mechanics to complex networks. In this paper, we present evidence that a commonly used expression for the partition function of a system of distinguishable particles leads to huge fluctuations of the number of particles in the grand canonical ensemble a...
