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 (EI ...Более
The convective oven ring cake baking process was investigated experimentally and numerically as a simultaneous heat and mass transfer process. The mathematical model described previously by the authors for cup cake baking was modified to simulate ring cake baking. The heat and mass transfer mechanisms were defined by Fourier’s and Fick’s second laws, respectively. The implicit alternating direction finite difference technique was used for the numerical solution of the representative model. Prior to the utilization of the developed model in predicting the temperature and moisture profiles for r ...Более
New sensing platform based on modified glassy carbon (GC) suitable for design of heavy metal-ion sensor is reported in this study. GC-based electrodes were electrochemically modified by poly-5-nitro-1,10-phenanthroline (poly-5NP) and poly-5-amino, 6-nitro-1,10-phenanthroline (poly-5A6NP) layers. Grafting of electrochemically formed poly-5NP and poly-5A6NP layers at the GC electrode surface was confirmed by electrochemical reduction of nitro groups into amine groups. Presence of grafted poly-5NP and poly-5A6NP layers and formation of their reduced forms on the GC electrode surface were verified ...Более
Twenty-six rabbits were used in this study. Two of them served as control subjects, and the remaining 24 underwent DO procedures in their left mandibular bodies. After a latency period of 5 days, 5 mm lengthening was performed at a rate of 1 mm/d. The rabbits in the experimental group were randomly divided into 4 subgroups and killed after 1, 2, 4, and 6 months. TMJs from both sides were harvested and prepared with hematoxylin and eosin stain for histomorphometric examination under an optical microscope.
The main objective of this article is to study self-sufficiency level of foreign language teachers in Foreign Languages High School of Kyrgyzstan-Turkey Manas University (KTMU). In this regard the significance of age, gender and nationality on self- efficacy is investigated. This study was conducted with the participation of Turkish, Kyrgyz, Russian and English teachers (citizens of Kyrgyzstan and Turkey) of High School of Foreign Languages, working in fall semester of 2011-2012 academic years. The total number of respondent is 110. The data obtained through Ohio Teacher Efficacy Scale (2001), ...Более
