Two-liquid flotation of sulphides: An electrochemical approach
(PERGAMON-ELSEVIER SCIENCE LTD, 2007)
The roles of pulp potential, collector and depressants on the flotation of pyrite, chalcopyrite and galena were studied by using two-liquid flotation technique. The potential was adjusted by reducing (Na2S and Na2S2O4) and ...
Fine dry grinding of zeolite in a laboratory ball mill
(WILEY-V C H VERLAG GMBH, 2003)
This paper presents the importance and usage of natural zeolites, which was recently recognized in the industry. Therefore, the grinding properties of natural zeolite were studied with the emphasis on a kinetic study in a ...
Spontaneous renal laceration as the presenting feature of polyarteritis nodosa in a patient with familial Mediterranean fever after hepatitis A infection
(SPRINGER, 2005)
We report a life-threatening spontaneous renal laceration with no history of bleeding diathesis or any trauma in a patient with FMF after acute hepatitis A virus (HAV) infection. Right nephrectomy was inevitable and ...
Force constant calculations for octahedral complexes of the type M(CO)(5)L, based on the CO-factored force field
(ELSEVIER SCIENCE SA, 2001)
Using the maximum value of the sum of the interaction constants, the CO-factored force field of octahedral M(CO)(5)L molecules was solved to give the relations which allow direct calculation of force constants from C-O ...
Swelling characterization of gamma-radiation induced crosslinked acrylamide/maleic acid hydrogels in urea solutions
(ELSEVIER SCI LTD, 2006)
Swelling behaviors of crosslinked acrylamide/maleic acid (CAMA) hydrogels synthesized by gamma-radiation crosslinking of acrylamide and maleic acid in aqueous urea solutions were investigated. CAMA hydrogels containing ...
Evaluation of cerebral vasospasm with transcranial magnetic stimulation: an experimental study
(SPRINGER-VERLAG, 2001)
Despite the current use of several different methods for diagnosis and follow-up of cerebral vasospasm after subarachnoid hemorrhage, an easy, quick, reliable, and noninvasive method is still needed for evaluation of this ...
Relationship between neutrophil functions and severity of periodontitis in obese and/or type 2 diabetic chronic periodontitis patients
(QUINTESSENCE PUBLISHING CO INC, 2008)
Objectives: Obesity and diabetes are the most common nutritional and endocrine disorders in developed and developing countries and are related to immune response alterations. Recent studies suggest an association among ...
FINITE ELEMENT ANALYSIS OF VALENCE BAND STRUCTURE OF SQUARE QUANTUM WELL UNDER THE ELECTRIC FIELD
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
Valence band structure with spin-orbit (SO) coupling of GaAs/Ga1-xAlxAs square quantum well (SQW) under the electric field by a calculation procedure based on a finite element method (FEM) is investigated using the multiband ...
Screening of the antioxidative and antimicrobial properties of the essential oils of Pimpinella anisetum and Pimpinella flabellifolia from Turkey
(ELSEVIER SCI LTD, 2006)
The aerial parts of two endemic Pimpinella [Pimpinella anisetum Boiss. & Ball. and Pimpinella flabellifolia (Boiss.) Benth. ex Drude] were hydro-distilled to produce oils in the yields of 2.07% (v/w) and 2.61% (v/w), ...
Swell potential and shear strength estimation of clays
(ELSEVIER SCIENCE BV, 2009)
This paper deals with the indirect estimation of the two main parameters of cohesive soils (swell percent and shear strength) that play an important role in the deformation of structures. While the literature contains ...
