Structural Characterisation of a Polysaccharide from Radix Ranunculus ternati

A water soluble polysaccharide, HB-1, with a molecular weight of 23,930, was isolated from radix Ranunculi ternati. by hot water extraction, ethanol precipitation, deproteination，ultrafiltration and gel-filtration column chromatography. Its sugar composition was determined by GLC as Glc, Ara, and Gal in a molar ration of 16.071: 2.722: 1. And the absolute configuration of Glc was identified as ...

Preparation and Characterisation of Immunoadsorbents for High Performance Liquid Affinity Chromatography (HPLAC)

The efficacy of activation methods and coupling were studied in the context of performance in batch and fixed bed binding experiments utilizing cell culture fluids or blood plasma as feedstock. Conclusions were drawn regarding selection of solid phase according to pore size, rigidity, pH stability, Chemistry of derivation and activation, and gross concentration of immobilized ligand require...

Attitudes towards English Language Norms in the Expanding Circle: Development and Validation of a new Model and Questionnaire

This paper describes the development and validation of a new model and questionnaire to measure Iranian English as a foreign language learners’ attitudes towards the use of native versus non-native English language norms. Based on a comprehensive review of the related literature and interviews with domain experts, five factors were identified. A draft version of a questionnaire based on those f...

$Z_k$-Magic Labeling of Some Families of Graphs

For any non-trivial abelian group A under addition a graph $G$ is said to be $A$-textit{magic}  if there exists a labeling $f:E(G) rightarrow A-{0}$ such that, the vertex labeling $f^+$  defined as $f^+(v) = sum f(uv)$ taken over all edges $uv$ incident at $v$ is a constant. An $A$-textit{magic} graph $G$ is said to be $Z_k$-magic graph if the group $A$ is $Z_k$  the group of integers modulo $k...
