High-Throughput Identification and Screening of Novel Methylobacterium Species Using Whole-Cell MALDI-TOF/MS Analysis
(Public Library Science, 2012)Methylobacterium species are ubiquitous alpha-proteobacteria that reside in the phyllosphere and are fed by methanol that is emitted from plants. In this study, we applied whole-cell matrix-assisted laser desorption/ionization ... -
Methylobacterium gnaphalii sp nov., isolated from leaves of Gnaphalium spicatum
(Soc General Microbiology, 2012)A pink-pigmented, facultatively methylotrophic bacterium, strain 23e(T), was isolated from the leaves of Gnaphalium spicatum (cudweed). The cells of strain 23e(T) were Gram-reaction negative, motile and non-spore-forming ... -
Bernstein Series Solution of a Class of Lane-Emden Type Equations
(Hindawi Ltd, 2013)The purpose of this study is to present an approximate solution that depends on collocation points and Bernstein polynomials for a class of Lane-Emden type equations with mixed conditions. The method is given with some ... -
The effective presentation of inquiry-based classroom experiments using teaching strategies that employ video and demonstration methods
(Australasian Soc Computers Learning Tertiary Education-Ascilite, 2013)This study was conducted in the light of the philosophical framework of inquiry-based science education. The research involved the presentation of experiments on basic science concepts that have been tested for validity ... -

Azorhizobium oxalatiphilum sp nov., and emended description of the genus Azorhizobium
(Microbiology Soc, 2013)A Gram-negative, motile, non-spore-forming rod, designated NS12(T), was isolated from macerated petioles of Rumex sp. after enrichment with oxalate. On the basis of 16S rRNA gene sequence similarity, strain NS12(T) was ... -
Methylobacterium haplocladii sp nov and Methylobacterium brachythecii sp nov., isolated from bryophytes
(Microbiology Soc, 2013)Pink-pigmented, facultatively methylotrophic bacteria, strains 87e(T) and 99b(T), were isolated from the bryophytes Haplocladium microphyllum and Brachythecium plumosum, respectively. The cells of both strains were ... -
Investigation of pre-service science teachers' attitudes towards laboratory safety
(Elsevier Science Bv, 2015)The purpose of the current study is to investigate the pre-service science teachers' attitudes towards laboratory safety in relation to variables such as gender, the state of participating in laboratory applications during ... -
Effect of Two-tier Diagnostic Tests on Promoting Learners' Conceptual Understanding of Variables in Conducting Scientific Experiments
(Routledge Journals, Taylor & Francis Ltd, 2015)Taking a test generally improves the retention of the material tested. This is a phenomenon commonly referred to as testing effect. The present research investigated whether two-tier diagnostic tests promoted student ... -
THINKING IN TERMS OF VARIABLES: THE CONCEPT OF THE SHADOW
(Sci Methodical Ctr-Sci Educologica, 2015)The aim of the research was to explore the ideas prospective science teachers (N=51) had about the variables of object size, shape and light transmission that have an impact on shadow formation, using a scientific activity ... -
ENVIRONMENT EDUCATION THROUGH OUTDOOR SCIENCE ACTIVITIES: LIGHT POLLUTION CASE
(Scibulcom Ltd, 2015)Although many environmental issues are included in 'Environmental Problems and Their Impacts' topic in the Science curriculum in middle schools in Turkey, light pollution is not mentioned. Yet, light pollution is an important ... -
PRE-SERVICE SCIENCE TEACHERS PERCEPTION OF GREENHOUSE EFFECT
(Scibulcom Ltd, 2015)The purpose of the present study is to investigate the pre-service science teachers perception of greenhouse effect in terms of its effects, causes and possible solutions on the basis of the variables of gender, grade level ... -
PRE-SERVICE SCIENCE TEACHERS OPINIONS ABOUT ETHICAL PRINCIPLES AND THE INVESTIGATION OF THEIR MORAL VALUES
(Scibulcom Ltd, 2015)In this study were investigated the opinions of pre-service science teachers about some ethical principles and their moral values that were acknowledged by them. For this purpose, this study has been carried out with ... -
Pre-service Science Teachers' Understanding of One-Dimensional Motion Graphs in the Kinematic Context
(Elsevier Science Bv, 2015)The aim of this study is to examine pre-service science teachers' understanding of graphs in kinematic context. This study focuses on one-dimensional motion graphs. The participants in this study are 115 pre-service science ... -
Turkish Students' Science Performance and Related Factors in PISA 2006 and 2009
(Springer, 2015)The OECD's Programme for International Student Assessment (PISA) enables participating countries to monitor 15-year old students' progress in reading, mathematics, and science literacy. The present study investigates ... -
Primary Pre-Service Teachers' Epistemological Beliefs and their Teaching and Learning Experiences
(Modestum Ltd, 2015)The epistemological beliefs of pre-service teachers influence both their teaching experiences and their students' content understanding. Little research has been devoted to the interaction between teachers' epistemological ... -
Methylobacterium Species Promoting Rice and Barley Growth and Interaction Specificity Revealed with Whole-Cell Matrix-Assisted Laser Desorption/Ionization-Time-of-Flight Mass Spectrometry (MALDI-TOF/MS) Analysis
(Public Library Science, 2015)Methylobacterium species frequently inhabit plant surfaces and are able to utilize the methanol emitted from plants as carbon and energy sources. As some of the Methylobacterium species are known to promote plant growth, ... -
Demonstrating the Direction of Angular Velocity in Circular Motion
(Amer Assn Physics Teachers, 2015)Rotational motion is ubiquitous in nature, from astronomical systems to household devices in everyday life to elementary models of atoms. Unlike the tangential velocity vector that represents the instantaneous linear ... -
Taylor collocation approach for delayed Lotka-Volterra predator-prey system
(Elsevier Science Inc, 2015)In this study, a numerical approach is proposed to obtain approximate solutions of the system of nonlinear delay differential equations defining Lotka-Volterra prey predator model. By using the Taylor polynomials and ... -
Turkish preservice science teachers' socioscientific issues-based teaching practices in middle school science classrooms
