soil and sludge samples based on it, in addition to the total elemental concentrations (Vercoutere et al., 1995; It is important to evaluate different digestion methods to accurately Quevauviller et al., 1993). In many countries (excluding determine elemental concentrations in soils. Three commonly used digestion procedures, hotplate aqua regia, microwave aqua regia, and the USA), this procedur...

This paper describes a method to obtain state model parameters for an infinite series of Links–Gould link invariants LG, based on quantum R matrices associated with the (0̇m | α̇n) representations of the quantum superalgebras Uq [gl(m|n)]. Explicit details of the state models for the cases n = 1 and m = 1, 2, 3, 4 are supplied. Some evaluations of the new link invariants are provided, as are some...

Significant amounts of ursodeoxycholic acid (UDCA) used for the treatment of patients with primary biliary cirrhosis (PBC) become epimerized at C-3 to isoUDCA. We investigated the metabolism of isoUDCA and a possible pharmacologic effect in five patients (51.4 5.8 years old; 3 females, 2 males) with PBC and persistent elevations of -glutamyl transpeptidase ( -GT) and alkaline phosphatase despit...

Aim of present study is to prepare PLGA nanoparticle. Nanoparticles were prepared by double emulsification solvent evaporation method. Various formulation and process variable which could affect the preparation and properties of nanoparticles. These formulation variables were identified and optimized to get uniform preparation with highest encapsulation efficiency. Formulation variables include...
