A model for extended bench casting in dipping coal seam
(NATL INST SCIENCE COMMUNICATION, 2007)
This paper deals with extended bench casting with draglines in surface coalmines. A computer model, developed for panel design, covers three fundamental operating modes: i) level casting for flat-lying coal seam; ii) ...
Platinum-group element, stable isotope, and fluid inclusion investigation of the ultramafic rock-hosted Gunes-Sogucak Ni-Cu-sulfide mineralization in the Gunes ophiolite, East-Central Turkey
(TAYLOR & FRANCIS INC, 2007)
Cunes-Sogucak Ni-Cu-sulfide mineralization in the Divrigi district of Sivas Province is genetically related to I.ate Cretaceous ultramafie rocks. Disseminated mineralization is scattered through the ultramafic rocks, whereas ...
Concentration of heavy metals in water and chub, Leuciscus cephalus (Linn.) from the river Yildiz, Turkey
(TRIVENI ENTERPRISES, 2007)
The concentration of heavy metals (Cu, Fe and Zn) were determined by atomic absorption spectrophotometry in the river water and the edible muscle tissues of chub, Leuciscus cephalus, from river Yildiz, Turkey and in the ...
Pb-207-(206) Pb single-zircon evaporation ages of some granitoid rocks reveal continent-oceanic island arc collision during the Cretaceous geodynamic evolution of the central Anatolian crust, Turkey
(PERGAMON-ELSEVIER SCIENCE LTD, 2007)
(207) Pb-Pb-206 single-zircon evaporation age determinations carried out on nine different granitoid units of central Anatolia, Turkey have yielded three distinct granitoid groups with different emplacement ages. These are ...
Evaluation of chewing muscles in patients with Parkinson using electromyography-interference pattern analysis
(UNIVERSITATSVERLAG ULM GMBH, 2007)
Electrical activity of muscles is defined in a spectrum varying from poor to maximal effort with EMG-Interference Pattern Analysis (IPA) methods. This method provides information about changes in motor units in all levels ...
Investigation of relaxant effects of propofol on sheep sphincter of Oddi
(KARGER, 2007)
Background/Aims: Intravenous anesthetics are often used for conscious sedation in endoscopic retrograde cholangio-pancreatography ( ERCP) and endoscopic sphincter of Oddi ( SO) manometry. This study was designed to investigate ...

(BLACKWELL PUBLISHING, 2007)
Background: The purpose of this study was to emphasize the clinical and imaging findings of 19 child cases of cerebral hemiatrophy. Methods:A total of 11 male and eight female patients underwent assessment with computed ...
The modification and characterization of maleic anhydride-styrene-methyl metacrylate terpolymer by poly(ethylene adipate)
(ELSEVIER SCIENCE BV, 2007)
In this study, the functionality of maleic anhydride was utilized in the maleic anhydride-styrene-methyl metacrylate (MAStMMA) terpolymer. First, the polyester of poly(ethylene adipate), PEA, polycondensation copolymer was ...
Investigation of effects of reactive copolymer containing maleic anhydride on thermomechanical properties of ternary blends of poly(methyl metacrylate) (PMMA)
(MANEY PUBLISHING, 2007)
In the present paper, the effects of reactive copolymer containing maleic anhydride on the thermomechanical properties of poly(methyl metacrylate) (PMMA) were investigated. Maleic anhydride-styrene (MA-St) and aniline ...
A kinetic study on the conversion of celestite (SrSO4) to SrCO3 by mechanochemical processing
(ELSEVIER SCIENCE BV, 2007)
The direct conversion of celestite (SrSO4) to Strontium carbonate by mechanochemical processing was studied under wet milling conditions by varying the amount of sodium carbonate with respect to the stoichiometric amount ...
