Indirect estimation of the swelling percent and a new classification of soils depending on liquid limit and cation exchange capacity
(ELSEVIER SCIENCE BV, 2006)
This paper describes the dependence of the swell percent (%S) on the soil properties, namely, liquid limit (LL) and cation exchange capacity (CEC). This study provides the statistical model that can be used to obtain an ...
Prediction of the wettability characteristics of some minerals from their breakage parameters
(ELSEVIER SCIENCE BV, 2003)
In this contribution, the breakage and wettability properties of calcite and barite minerals were presented and some correlations were established between these experimentally determined parameters. The gamma(c) relates ...
Target peptide recognition by S100P protein and role of central linker region and dimer interface
(BENTHAM SCIENCE PUBL LTD, 2006)
Interaction between S100P and its target protein is an essential step in several cellular functions. The amphiphatic mellitin peptide binds tightly to S100P protein in the presence of calcium cation. Since little is known ...
The limits of the family Evaniidae (Insects : Hymenoptera) and a new genus from Lebanese Amber
(BRILL ACADEMIC PUBLISHERS, 2002)
The definition of the family Evaniidae is revised and Cretevaniidae are synonymised with Evaniidae based on evidence derived from recently described Mesozoic taxa and a new genus and species, Lebanevania azari, described ...
A case study of crushing resistance of Anatolian sands at lower and higher density
(SPRINGER HEIDELBERG, 2008)
Particle breakage occurs when the stresses imposed on soil particles exceed their strength. In order to determine the crushing resistance, Anatolian sands were collected from three different locations in Turkey. Mineralogical, ...
Nifedipine Enhances the Relaxant Effects of Cyclo-Oxygenase Inhibitors on the Bovine Ciliary Muscle
(MARY ANN LIEBERT, INC, 2008)
Background/Aims: The inhibition of cyclo-oxygenase (COX) enzymes and the blockade of Ca2+ channels play an important role in the regulation of smooth muscle relaxation. This study was designed to investigate the relaxant ...
A prospective study on the clinical performance of polysiloxane soft liners: One-year results
(JAPANESE SOC DENTAL MATERIALS DEVICES, 2008)
Objective: The aim of the present study was to evaluate the clinical performance of four denture soft liners up to 12 months. Materials and methods: Thirty-three edentulous patients who experienced difficulties when using ...
The Retrospective Annual Surgical Incidence of Cystic Echinococcosis in Sivas, Turkey
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Cystic echinococcosis is an important public health problem in our region. The aim of this study was to assess the surgical incidence of cystic echinococcosis in Sivas, Turkey. A retrospective follow-up study was carried ...
4-(9-Anthryl)-1-(3-bromophenyl)spiro[azetidine-3,9 '-xanthen]-2-one
(WILEY-BLACKWELL, 2009)
In the title molecule, C35H22BrNO2, the four-membered ring of the beta-lactam unit is nearly planar [maximum deviation = 0.003 (3) angstrom] and makes dihedral angles of 87.07 (15), 59.80 (16) and 20.81 (19)degrees, ...
A study on friction and wear behaviour of carburized, carbonitrided and borided AISI 1020 and 5115 steels
(ELSEVIER SCIENCE SA, 2003)
The friction and wear characteristics of AISI 1020 and 5115 steel surfaces improved by various thermochemical heat treatments such as carburizing, carbonitriding and boronizing were determined. Samples prepared from the ...
