This study examines the factors affecting the possibility of owning a house in Turkey using probit models. Moreover, it focuses on the heteroscedasticity problem that is ignored in most of the probit applications. The results obtained from the study indicate that besides the demographic characteristics of the head of the household, education, employment, and income are also influential factors in regard to home ownership. Besides these things, evidence indicates that the choice to live in either rural or urban areas has a significant impact on home ownership.
In this study, West Nile Virus antibody presence (WNV) in white leghorn chickens located in various commercial domestic chicken establishments in Konya was studied serologically. Blood sampling from 380 white leghorn chickens within the age range of 20-40 weeks was carried out. Blood serum samples were studied by West Nile Competition ELISA kit. All samples were found seronegative.
Previous studies in our lab and elsewhere showed that different microbial gene groups are obtained from geographically distant sites. Alkane monooxygenases activate terminal carbon-carbon bonds in the first step of alkane degradation with the addition of an oxygen to the compound, resulting in an alcohol product. The aim of this study was to test the hypothesis that unique microbial populations and alkane monooxygenase (alkB and Cytochrome P450) genes can be recovered from geographically distinct sites, with varying degrees of anthropogenic impact. Sediment was collected from six river and stream sites with various levels of human i . . .mpact located in Bishkek, Kyrgyzstan as well as Dushanbe and Khorog, Tajikistan, in Central Asia. The sites included rural and mountain streams, as well as rivers near or in cities. All sediments were enriched in media containing hexadecane as a carbon source and subcultured into fresh media with the alkane two times. DNA was extracted from each enrichment culture at various points throughout the enrichment for 16S rRNA and alkB clone library construction. The enrichment cultures were also analyzed by terminal restriction fragment length polymorphism (TRFLP) analysis of both 16S rRNA and alkB genes. The alkB and P450 genes, as well as 16S rRNA, were targeted with 454 pyrosequencing to obtain an estimate of microbial and alkane hydroxylase diversity at the sample locations and enrichments. The data show that distinct populations of alkB and P450 genes can be enriched from different locations and countries in Central Asia confirming that there is a wide diversity of alkane degrading genes in the environment

Within FATIH Project, it's aimed to use information technology more effectively in learning environments and targeted to make technological infrastructure improvements in schools. For this process information technology teachers play a key role. Thus, Information Technologies (IT) pre-service teachers' computer self-efficiency perceptions were examined. In the study, a survey model was used and the sample included 200 Computer Education and Instructional Technologies (CEIT) students in two different universities. Relationships between the perceptions of computer self-efficacy of CEIT students and variables such as gender, graduated . . .high school type, place of department preference, grade level and university type were examined by using computer self-efficacy scale that was developed by Orhan ve Akkoyunlu (2003). As a result, it's indicated that; Male pre-service teachers have higher computer self-efficacy perceptions than female pre-service teachers, Pre-service teachers that were graduated from vocational high school have higher computer self-efficacy perceptions than pre-service teachers that were graduated from general high school, Junior and senior pre-service teachers have higher computer self-efficacy than freshmen. Finally, the research indicated that place of department preference have no effect on the computer self-efficacy perceptions, also there isn't a significant difference in computer self-efficacy perceptions among pre-service teachers from different universities.-
Fatih Projesi kapsamında Bilişim Teknolojilerinin, öğrenme ortamlarında daha etkin kullanımı amaçlanmaktadır. Ayrıca tüm okullarda teknolojik altyapı iyileştirmelerinin yapılması hedeflenmektedir. Söz konusu sürecin işletilebilmesi için Bilişim teknolojileri öğretmenleri kilit rol oynayacaktır. Bu nedenle, araştırmada Fatih projesini sürdürecek olan Bilişim teknolojileri öğretmenliği adaylarının bilgisayar öz yeterlik algıları tarama modeli kullanılarak incelenmiştir. Çalışma grubunu iki farklı üniversitenin Bilgisayar ve Öğretim Teknolojileri Eğitimi bölümünde (BÖTE) öğrenim gören 200 öğrenci oluşturmuştur. Araştırmada Akkoyunlu ve Orhan (2003) tarafından geliştirilen “Bilgisayar öz yeterlik ölçeği” kullanılarak, öğrencilerin bilgisayar öz yeterlik algıları ile cinsiyet, mezun olunan ortaöğretim türü, bölüm tercih sırası, devam edilen sınıf ve okuduğu üniversite değişkenleri arasındaki ilişkiler incelenmiştir. Araştırma sonucunda, erkek öğrencilerin kız öğrencilere göre, meslek lisesi mezunu öğrencilerin, genel lise mezunu öğrencilere göre, 3 ve 4. sınıfa devam eden öğrencilerin 1. sınıf öğrencilerine göre daha yüksek bilgisayar öz yeterlik algısına sahip olduğu görülmüştür. Bölüm tercih sırasının bilgisayar öz yeterlik algısını etkilemediği bulgularına ulaşılmıştır

A new calix[4]pyrrole functionalized vic-dioxime, 3-(4-methyl-9,9,14,14,19,19-hexaethylcalix[4]pyrrole)benzoaminoglyoxime (LH2) was synthesized from anti-chloroglyoxime and 3-aminophenyl-calix[4]pyrrole at room temperature. The mononuclear complexes {nickel(II), copper(II) and cobalt(II)} of this vic-dioxime ligand were prepared and their structures were confirmed by elemental analysis, IR and UV–Vis spectrophotometry, magnetic susceptibility; the MS, 1H and 13C NMR spectra of the LH2 ligand and its Ni(II) complex were also recorded. The experimental results indicated that the ligand:metal ratio was 2:1 in the cases of Ni(II), Cu(II . . .) and Co(II) complexes as is with most vic-dioximes. Electrochemical properties of the ligand, and its complexes were investigated in DMSO solution by cyclic voltammetry at 200 mV s−1 scan rate. -

This study reports the electrochemical modification of glassy carbon (GC) surface with etodolac (ETO), the characterization of this ETO modified glassy carbon (ETO/GC) electrode and its electroanalytical application for the determination of Pb(II) ions. Binding type of the etodolac with the glassy carbon surface was investigated and found that it was through the etheric linkage revealed from the reflection–absorption infrared spectroscopy (RAIRS). The ETO/GC electrode was characterized by cyclic voltammetry (CV), reflection–adsorption IR spectroscopy, electrochemical impedance spectroscopy (EIS), X-ray photoelectron spectroscopy (XP . . .S) and atomic force microscopy (AFM). The ETO/GC electrode was found to be suitable for selective determination of Pb(II) by adsorptive stripping voltammetry in the solutions of the mixture of heavy metal ions, such as Cu(II) and Cd(II) and showed high stability and reproducibility. The stability and the potential range of the ETO/GC electrode were also studied. The developed method was validated according to the ICH guideline and found to be linear, sensitive, selective, precise and accurate. The linearity range of Pb(II) was 5.0 × 10−10 to 1.0 × 10−8 M with the detection limit (S/N = 3) of 1.67 × 10−10 M. The validated method was applied successfully for the determination of Pb(II) in real samples. -
