Many chemicals to which animals or plants are exposed undergo metabolism prior to storage in, or excretion by, the organism. In some cases, measurement of the levels of metabolites in tissues or excretion products can be used as an indicator of exposure to such chemicals. Measurement of metabolites as a means of monitoring exposure may be especially valuable when practical difficulties exist in...

Aggregative data infrastructures (ADIs) are information systems where organizations can find the tools to integrate their data sources to form uniform and richer information spaces of object metadata descriptions. Novel sustainable approaches for the realization of ADIs are based on the adoption of ADI enabling technologies which support the realization, maintenance and upgrade of ADIs and prom...

NMR analysis of GI-20 in three micelles revealed that arginine side-chain H resonances are well resolved in dioctanoylphosphatidylglycerol (D8PG), allowing observations of peptide-lipid interactions. Structural differences in SDS and D8PG underscore caution with the use of SDS. Peptide chemical shifts are proposed to be a useful indicator of mi-

The Zarivar Lake a freshwater lake in west of Kurdistan Province is home for large number of native plant and animal species therefore water quality and health of the lake are vital for conservation of these species. The present study aimed at evaluation of the Zarivar Lake using NSF- WQI as an indicator of water quality. WQI is a suitable tool to examine and classify spatial and temporal varia...

better understanding and recognizing the amount of cultural development in iranian provinces and comparing them, causes a particular attention and helps to recognize their weaknesses, strengths, potentialities and deficiencies. the purpose of this paper is to analyze cultural development indicators in iran. the writers of this article present an applied research and use a comparative method. us...

We apply rule induction to mine for knowledge in a database which stores data obtained by monitoring the water quality of the rivers in Slovenia. The database contains measurement data about the physical and chemical properties of the water at different measurement sites, as well as data about the presence of living organisms. Taken together, the above data reflect the quality of the water: the...

In traditional herbal medicine, comprehensive understanding of bioactive constituent is important in order to analyze its true medicinal function. We investigated the chemical properties of medicinal and edible ginger cultivars using a liquid-chromatography mass spectrometry (LC-MS) approach. Our PCA results indicate the importance of acetylated derivatives of gingerol, not gingerol or shogaol,...

The chemical shift difference (delta[13C(beta)]-delta[13C(gamma)]) is a reference-independent indicator of the Xaa-Pro peptide bond conformation. Based on a statistical analysis of the 13C chemical shifts of 1,033 prolines from 304 proteins deposited in the BioMagRes database, a software tool was created to predict the probabilities for cis or trans conformations of Xaa-Pro peptide bonds. Using...
