We measured the absorption spectrum (340-640 nm) of the purest available water with photothermal deflection spectroscopy. Our spectrum exhibits an absorption minimum in the blue region of the spectrum that is deeper than in most previously documented pure-water absorption studies. We attribute this to exceptional sample purity and our technique's inherent freedom from scattering effects. Becaus...

Introduction: As the absorption of radiation in environment is increasing, the present study was performed to evaluate the knowledge and practices of Babol’s dentists about x-ray protection . Materials &Methods: This cross-sectional study was designed to assess the knowledge and practices of dentists. The questionnaires were distributed among 70 dentists in Babol city. Analysis of the ...

We present a novel optimization of evaluating object queries, especially instance queries, over description logic knowledge bases. The method is designed to perform well for large ABoxes and expressive TBoxes, e.g., where background knowledge requires the use of disjunction and negation. The method significantly improves the performance of answering object queries, and particularly so in cases ...

absence of nutritional knowledge is one of the most important reasons of nutritional deficiencies. the aim of this study was to evaluate knowledge, attitude and practices of women about iron deficiency anemia in yazd and orumiyeh. this cross-sectional study was performed on 298 and 242, 15-49 year- old women in yazd and orumiyeh, respectively. questionnaires were prepared to collect the partici...

Good and extensive experimental ADMET (absorption, distribution, metabolism, excretion, and toxicity) data is critical for developing reliable in silico ADMET models. Here we develop a PharmacoKinetics Knowledge Base (PKKB) to compile comprehensive information about ADMET properties into a single electronic repository. We incorporate more than 10 000 experimental ADMET measurements of 1685 drug...
