X-ray crystallography showed that the title compound, C(6)H(12)O(5), crystallizes in the α-pyran-ose form with the six-membered ring in a chair conformation. The crystal structure exists as a three-dimensional hydrogen-bonded network of mol-ecules with each mol-ecule acting as a donor and aceptor for four hydrogen bonds. The absolute configuration was determined by the use of l-fucose as starti...

BACKGROUND Clinical and epidemiological studies have given discordant results on the usefulness of the level of circulating elastin peptide (EP), a potential marker of both elastin destruction (a key phenomenon in pulmonary emphysema) and neosynthesis, for assessing structural changes in the lung extracellular matrix. The aim of the present study was to explore the relationship between levels o...

Background: Ectopic pregnancy (EP) is a common condition which presents a major health problem for women of childbearing age. This study aims to analyze and identify risk factors that have the potential for EP and evaluating the contribution of the risk factors associated EP. Materials and Methods: In this case control study, performed from 2006 to 2011 at Arash hospital, the casepatients were ...

Lignocelluloses residues from the post-harvest crop are receiving great scientific attention nowadays. Generally, composite materials based on lignocelluloses waste present low density and weight, better insulation properties compared with those petroleum-based. This study presents results of experimental investigations regarding soundproofing capabilities for a material expanded perlite (EP) n...

In this paper, we introduce a new generalized inverse, called MPWG inverse of complex square matrix. We investigate characterizations, representations, and properties for inverse. Then, by using the core-EP decomposition, discuss relationships between other inverses. A variant successive matrix squaring computational iterative scheme is given calculating The Cramer rule solution singular equati...

ectopic pregnancy (ep) and miscarriage are important differential diagnosis of first trimester vaginal bleeding. in first trimester, serum progesterone value can be 5-20 ng/ml in ep and miscarriage. since delay in diagnosis of ep could have high mortality and morbidity, the aim of this study was comparison of serum progesterone value in ep and miscarriage in order to differentiate these conditi...

background: ectopic pregnancy (ep) is a prevalent problem and the most common cause of maternal mortality at the first trimester. results from different studies are not consistent regarding the risk factors associated with ep. the current study aimed to investigate about risk factors associated with ep in kermanshah-iran. methods: a case–control study conducted to compare risk factors of ep amo...

Linear Complementarity Problems (LCPs) belong to the class of NP-complete problems. Therefore we can not expect a polynomial time solution method for LCPs without requiring some special property of the coefficient matrix. Following our recently published ideas we generalize affine scaling and predictor-corrector interior point algorithms to solve LCPs with general matrices in EP-sense, namely, ...

A k x k matrix A = [aU lover a field F is called circulant if aij = a (j-i) mod k' A [2k ,k l linear code over F = GF (q) is called double-circulant if it is generated by a matrix of the fonn [I A l, where A is a circulant matrix. In this work we ftrst employ the Fourier transform techJ nique to analyze and construct se:veral families of double-circulant codes. The minimum distance of the resul...
