The effect of strontium-containing silicon-doped hydroxyapatite ceramics on bone defect healing
Kerman, Gözde; Korkusuz, Feza; Volkan, Mürvet; Department of Biotechnology (2011)
Hydroxyapatite (HA) based bioceramics have been developed to treat bone defects for the last 30 years. Doping HA with elements is a common approach to increase mechanical strength, biocompatibility and osteointegrity. Bone morphogenetic protein (BMP)-containing bioceramic composites enhance osteointegrity and induce bone formation. Strontium (Sr) is currently used to treat osteoporosis clinically as this element inhibits bone resorption and stimulates bone formation. In this study, HA was doped with silicon...
The effect of 7E learning cycle model on the improvement of fifth grade students’ critical thinking skills
Mecit, Özlem; Öztekin, Ceren; Department of Secondary Science and Mathematics Education (2006)
The main purpose of the present study was to investigate the effect of 7E learning cycle model as an inquiry-based learning on the improvement of 5th grade students’ critical thinking skills. This study was conducted during 2005-2006 spring semester in a private primary school in Sakarya. A total of 46 fifth grade students from two different classes of the same science teacher was involved in the study. Two classes were randomly assigned as experimental group and control group. While students in the control...
The Effects of Biostimulants on Nutrient Uptake of 'Syrah' Vine Saplings Grafted on SO4 Rootstock
Polat, A.; GÜRSÖZ, SADETTİN; BENGİSU YAVUZER, AYŞE GÜLŞAH; Polat, I. H. (2012-03-31)
This study was conducted to determine the effects of two different biostimulants (Agrozym and Almina) with their four different concentrations (0, 5, 10, 20 g per pot), for plant characteristics of 'Syrah' vine saplings and soil structure in 2006. The experiment was done with 5 repetitions and each replica consisted of 3 plants. Plant and soil samples were collected and analyzed two months after budding. According to results obtained, while macro plant nutrient of levels (N, P, K, Ca, Mg, S) did not change,...
The Heuristic role of questions in the formation of research programmes: Copernicus’s heliocentric system
Altuğ, Sezen; Bağçe, Samet; Department of Philosophy (2016)
The aim of this thesis is to develop a critical view about the notion of the heuristic in Lakatos’s methodology of research programmes. The heuristic is tried to be sterilized from its defects with an insight derived from different forms of theories dealing with questions. For that reason, a short survey which includes Socratic dialogues, Hintikka’s theory of interrogative games, van Fraassen’s theory of why-questions, and Laudan’s analogy between science and problem-solving activity is introduced. As a res...
Properties of light emitting diodes following cobalt-60 irridiation
Özcan, Şafak; Günal, İbrahim; Department of Physics (2004)
The main purpose of this study is to investigate the effects of gamma radiation on the properties of the light emitting diodes. GaP and GaAsP LEDs are used in the study. It is observed that the exposure of a light emitting diode affects its various properties. A cobalt-60 gamma-cell is used to irradiate the selected light emitting diodes. For the different total doses of gamma pre-irradiation and post-irradiation I-V characteristics and spectral responses are recorded. The capacitance characteristics are me...
