A Comparison of the Mathematical Skills of First Graders with and without Preschool Education
(EDAM, 2009)
The purpose of this study is to compare the mathematical skills of first grade elementary students who had or had not taken preschool education. The sample of the study consists of 150 elementary students, those with and ...
Effects of experimental obstructive jaundice on contractile responses of dog isolated blood vessels: Role of endothelium and duration of bile duct ligation
(BLACKWELL SCIENCE ASIA, 2000)
1. We examined the effects of experimental obstructive jaundice caused by bile duct ligation (BDL) on vascular smooth muscle function, as well as the underlying mechanisms involved, by recording responses to noradrenaline ...
Chlorhexidine gluconate: An ideal scolicidal agent in the treatment of intraperitoneal hydatidosis?
(SPRINGER, 2005)
Hydatid disease is a parasitic disease that is treated primarily by surgery. The most important complication of surgical treatment is spillage of the contents of the cyst, leading to secondary dissemination. In this study, ...
Rapid maxillary expansion and surgically assisted rapid maxillary expansion effects on nasal volume
(E H ANGLE EDUCATION RESEARCH FOUNDATION, INC, 2006)
The purpose of this study was to compare the effects of rapid maxillary expansion (RME) and surgically assisted rapid maxillary expansion (SARME) on nasal volume using acoustic rhinometric methods. Two groups of subjects ...
Dependence of film thickness on the structural and optical properties of ZnO thin films
(ELSEVIER SCIENCE BV, 2009)
ZnO thin films are prepared on glass substrates by pulsed filtered cathodic vacuum arc deposition (PFCVAD) at room temperature. Optical parameters such as optical transmittance, reflectance, band tail, dielectric coefficient, ...
Assessment of Alveolar Bone Levels from Bitewing, Periapical and Panoramic Radiographs in Periodontitis Patients
(UNIV WEST INDIES FACULTY MEDICAL SCIENCES, 2008)
The aim of this study was to determine the relationship between loss of radiographic crestal bone height in panoramic, bitewing and periapical radiography and to probe the attachment loss after periodontal treatment. ...
Periodontal Healing of Marginal Flap Versus Paramarginal Flap in Palatally Impacted Canine Surgery: A Prospective Study
(W B SAUNDERS CO-ELSEVIER INC, 2009)
Purpose: The aim of the present study was to compare the influence of 2 mucoperiosteal flaps, marginal and paramarginal, on the periodontal healing of adjacent maxillary teeth after extraction of palatally impacted canines. ...
Multi-objective optimization of some process parameters of a multi-gravity separator for chromite concentration
(ELSEVIER SCIENCE BV, 2008)
The multi-gravity separator (MGS) is one of the fine particle mineral concentration machines based on gravity separation. Concentration performance, indicators such as grade and recovery, depends on appropriate selection ...
Adsorption of some textile dyes by hexadecyltrimethylammonium bentonite
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 2001)
In this study, hexadecyltrimethylammonium (HDTMA) bentonite was synthesized by placing alkylammonium cation onto bentonite. Adsorption of some textile dyes such as Everdirect Supra Yellow PG, Everdirect Supra Orange 26 CG, ...
Sulfotransferase 1A1 (SULT1A1) polymorphism and susceptibility to primary brain tumors
(SPRINGER, 2008)
Purpose Sulfotransferase 1A1 is a member of sulfotransferase family that plays an important role in the biotransformation of numerous carcinogenic and mutagenic compounds through sulfation. The present study has investigated ...
