Message Sequence Chart (MSC) speci cations have found their way into many software engineering methodologies and CASE tools, in particular in the area of telecommunications and concurrent real-time systems. MSC Speci cations often represent early life-cycle requirements and high-level design speci cations. We are considering iterating and branching MSC speci cations according to ITU-T Recommend...

A reverse Monte Carlo analysis of neutron and x-ray total scattering data from two ceria-zirconia samples composition Ce0.75Zr0.25O2 is performed to analyze the distribution cations examine possibility oxide-ion disorder. For first material, heated in air under moderate conditions (800 °C), structure a single-phase solid-solution with statistical cations, but local tetragonal symmetry found, co...

A number of biological responses to angiotensin II have been demonstrated to be modulated acutely by cations, but the exact mechanism has not been elucidated. We have utilized a radioreceptor assay for angiotensin II to determine whether this acute regulatory mechanism could be related to a change in either number or affinity of angiotensin II binding to receptors. Three target tissues were use...

brane uptake of IFB, were completely reversible. These findings are consistent with the concept that the formation of calcium salt bridges is essential for attachment of IFB,2 to the ileal-absorptive surface.

A proton NMR method for the drtermination of salvation numbers of alkaline earth cations with hexamethyl phosphoramide (HMPA) in nitromethane (NM) as diluents is described. The method is based on monitoring the resonance frequency of HMPA protons as a function of HMPA / metal ion molar ratio at constant metalion concentration. The average salvation number of cations,  , at any HMPA / metal ...

We describe the qualitative and quantitative analysis of the complexation properties towards cations of a cyclic peptoid hexamer composed of alternating α- and β-peptoid monomers, which bear exclusively chiral (S)-phenylethyl side chains (spe) that have no noticeable chelating properties. The binding of a series of monovalent and divalent cations was assessed by 1H NMR, circular dichroism, fluo...

Abstract Background and purpose: According to the reported problems in area of the inappropriateness of water quality which used for washing and staining of car apparatuses in a car factory, this research was carried out for identification of physical, chemical, and microbiological characteristics of the consumed water in Babol car factory, Iran. Materials and Methods: Physical and chemical par...

We study the complexity of various combinatorial problems when instances are speci ed using one of the following succinct speci cations: (1) the 1-dimensional nite periodic narrow speci cations (denoted 1-FPN-speci cations) of Ford et al. and Wanke [FF58, Wa93]; (2) the 1-dimensional nite periodic narrow speci cations with explicit boundary conditions (denoted 1-FPN(BC)-speci cations) of Gale [...

Introduction Rivers are one of the most important water resources and it is very important to study their water quality. Therefore, in this study, sampling was done from 15 permanent waterway stations of Pirbadush and Gashun of Qolyan River in Lorestan province, which are located in the path of oil shales.   Materials and Methods  Hydro-geochemical parameters were calculated by analyzing t...
