INQUIRY-BASED SCIENCE LABORATORIES: AN ANALYSIS OF PRESERVICE TEACHERS' BELIEFS ABOUT LEARNING SCIENCE THROUGH INQUIRY AND THEIR PERFORMANCES
(SCI METHODICAL CTR-SCI EDUCOLOGICA, 2012)
This study investigated the effects of inquiry-based instruction on preservice teachers' beliefs concerning learning science through inquiry and their performance to apply a scientific inquiry process. A case study design ...
Study of direct and indirect exciton states in GaAs-Ga1-xAlxAs quantum dots under the effects of intense laser field and applied electric field
(SPRINGER, 2012)
The effects of intense laser radiation on the exciton states in GaAs-Ga1-xAlxAs quantum dots are studied with the inclusion of applied dc electric fields oriented along the growth direction of the system. The calculations ...
Diagenetic and very low-grade metamorphic characteristics of the Paleozoic series of the Istanbul Terrane (NW Turkey)
(SPRINGER BASEL AG, 2012)
The Istanbul Terrane along the Black Sea coast in NW Anatolia, is a Gondwana-derived continental microplate, comprising a well-developed Paleozoic succession. Petrographic and X-ray diffraction studies were performed on ...
Amoebicidal activity of the rhizomes and aerial parts of Allium sivasicum on Entamoeba histolytica
(SPRINGER, 2012)
Amebiasis is a severe illness caused by Entamoebachistolytica. The aim of this study is to evaluate the in vitro amebicidal activity of the rhizomes and aerial parts of Allium sivasicum, an endemic plant species from the ...
Alendronate enhances osseous healing in a rat calvarial defect model
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)
Aim: The aim of this study was to evaluate the effect of alendronate on osseous wound healing in an experimental model. Methods: Critical size defects were created in calvaria of 40 male Wistar rats. The animals were divided ...
Allgrove syndrome
(SINGAPORE MEDICAL ASSOC, 2012)
Allgrove syndrome is a rare autosomal recessive disorder. It is also known as the 3A syndrome and characterised by the triad of achalasia, alacrima and adrenal insufficiency. The AAAS gene is encoded on chromosome 12q13. ...
Primary Malignant Melanoma of the Nasal Cavity
(LIPPINCOTT WILLIAMS & WILKINS, 2012)
Primary malignant melanoma of the nose and paranasal sinus mucosa is a rare disease and seen in less than 1% among all melanomas. Malignant melanomas have 2 origins: cutaneous and mucosal. The mucosal form has a worse ...
The effect of intravenous pamidronate treatment for type i osteogenesis imperfecta patients have on their bone mineral density, fracture rate, and mobility
(DRUNPP-SARAJEVO, 2012)
Objective: Osteogenesis imperfecta (OI) is a genetic disorder caused by the mutation in encoding collagen type I, and characterised by fragile bone and reduced bone mineral density. The purpose of this study was to analyse ...
Thermodynamic parameters of TI+, Ra2+, Bi3+ and Ac3+ adsorption onto polyhydroxyethylmethacrylate-hydroxyapatite composite
(SPRINGER, 2012)
In this research, a new composite, poly (hydroxyethylmethacrylate-hydroxyapatite) [P(HEMA-Hap)], was synthesized and its adsorptive features for natural radionuclides (TI+, Ra2+, Bi3+ and Ac3+ in a leaching solution) were ...
Synthesis and characterization of a new low-cost composite for the adsorption of rare earth ions from aqueous solutions
(ELSEVIER SCIENCE SA, 2012)
We synthesized and characterized a novel composite, poly(acrylamide-expanded perlite) [P(AAm-EP)] and investigated its adsorptive features for Tb3+. We achieved the synthesis by using free-radical polymerization and a ...
