Construction of ferrocene modified conducting polymer based amperometric urea biosensor

DERVISEVIC, Muammer | DERVISEVIC, Esma | ŞENEL, Mehmet | ÇEVİK, Emre | YILDIZ, Hüseyin Bekir | ÇAMURLU, Pınar

Herein, an electrochemical urea sensing bio-electrode is reported that has been constructed by ﬁ rstly electropolymerizing 4-(2,5-Di(thiophen-2-yl)-1H-pyrrol-1-yl)aniline monomer (SNS-Aniline) on Pencil Graphite Electrode (PGE), then modifying the polymer coated electrode surface with di-amino-Ferrocene (DAFc) as the mediator, and lastly Urease enzyme through glutaraldehyde crosslinking. The e ﬀ ect of pH, temperature, polymer thickness, and applied potential on the electrode current response was investigated besides performing storage and operational stability experiments with the interferenc ...Daha fazlası

Tagging accuracy analysis on part-of-speech taggers

YUMUŞAK, Semih | DOĞDU, Erdoğan | KODAZ, Halife

Part of Speech (POS) Tagging can be applied by several tools and several programming languages. This work focuses on the Natural Language Toolkit (NLTK) library in the Python environment and the gold standard corpora installable. The corpora and tagging methods are analyzed and compared by using the Python language. Different taggers are analyzed according to their tagging accuracies with data from three different corpora. In this study, we have analyzed Brown, Penn Treebank and NPS Chat corpuses. The taggers we have used for the analysis are; default tagger, regex tagger, n-gram taggers. We h ...Daha fazlası

The Relationship of Emotional Intelligence and Breastfeeding Self-Efficacy in Mothers in the Early Postpartum Period

KARAKOÇ, Hediye | MUCUK, Özlem | ÖZKAN, Hava

Introduction: Women have widespread breastfeeding problems in postpartum period. Emotional intelligence (EI) is thought to be important in problem-solving related to breastfeeding. Research Aims: The study was conducted to investigate the correlation between the EI and breastfeeding selfefficacy (BFSE) of women in the early postpartum period and the associated factors. Materials and Methods: A cross-sectional study was conducted in cesarean-postpartum service of a hospital in Erzurum between May 2015 and May 2016. The sample of the study consisted of 271 women. The dependent variables constitu ...Daha fazlası

An evaluation of the relationship between violence exposure status and personality characteristics among infertile women

COŞKUNER POTUR, Dilek | ONAT, Güliz | DOĞAN MERİH, Yeliz

In this descriptive study, our aim was to examine the relationship between violence exposure status and personality characteristics among infertile women. The researchers collected data from 315 infertile women at an in vitro fertilization unit of the Woman and Child Disease Training and Research Hospital in Istanbul, Turkey. An introductory information form, the Eysenck Personality Questionnaire Revised-Abbreviated Form (EPQR-A), and the Infertile Women’s Exposure to Violence Determination Scale (IWEVDS) were used as data collection tools. When the relationship between the IWEVDS and EPQR-A s ...Daha fazlası

Three spirals: Breastfeeding problems, growth spurts, and postpartum depression

ONAT, Güliz | KARAKOÇ, Hediye

Purpose: The inadequacy experienced in maintaining breastfeeding was tried to be understood within the framework of Meleis' theory, and its relationship with growth spurts and postpartum depression was attempted to be revealed. Design and Methods: The study was planned in a case‐control type web‐based descriptive research design. Mothers (n = 572), who thought that they experienced breastfeeding problems, constituted the case group of the study, and mothers (n = 524), who thought that they did not experience breastfeeding problems, constituted the control group. Findings: A statistically signi ...Daha fazlası

Nonexistence results for parabolic equations involving the p-Laplacian and Hardy–Leray-type inequalities on Riemannian manifolds

GOLDSTEIN, Gisèle Ruiz | GOLDSTEIN, Jerome Arthur | KÖMBE, İsmail | BAKIM, Sümeyye

The main goal of this paper is twofold. The first one is to investigate the nonexistence of positive solutions for the following nonlinear parabolic partial differential equation on a noncompact Riemannian manifold M, ⎧ ⎪⎨ ⎪⎩ ∂u ∂t = Δp,gu + V(x)u p−1 + λuq in Ω × (0, T ), u(x, 0) = u0(x) ≥ 0 in Ω, u(x, t) = 0 on ∂Ω × (0, T ), where 1 < p < 2, V ∈ L1 loc(Ω), q > 0, λ ∈ R, Ω is bounded and has a smooth boundary in M and Δp,g is the p-Laplacian on M. The second one is to obtain Hardy- and Leray-type inequalities with remainder terms on a Riemannian manifold M that provide us concrete potentials ...Daha fazlası

Relationship of modernism, postmodernism and reflections of it on education

KAHRAMAN, Ayşe Derya

Making Modernism and Postmodernism a different sense of social life caused creation of different life and thinking styles. Modernism as a result of enlightening after the 18th century has taken its place in every area of the society. Post modern word has been defined as the further level of modernism. Every two kind of thinking styles have been effective at every point of life, also it affected education.

The aim of this study is to conduct validity and reliability study of the Environmental Awareness and Attitude Scale for Preschool Children .This study is conducted with 310 children who are having preschool education. At the end of the factor analysis results, there are three factors that explain 44.02% of the total variance in Environmental Attitude subscale. In the Environmental Awareness subscale, 3 factors that explain 40.94% of total variance were found. The correlation coefficients between the factors of the Environmental Awareness subscale were r =.80, .78 and .83 and for the Environme ...Daha fazlası
