Background Most of the studies and interventions are targeted to address undernutrition, but childhood obesity has become a silent killer among children. Developing countries, including Turkey, could recognize the importance of the issue now and have begun to discuss the necessity of studies on this subject. Therefore, this study aims to examine the prevalence of obesity among pre-school children in Turkey. Methods The data source of this study is the Turkey Demographic and Health Survey (TDHS)-2013. The TDHS-2013 was a sample study to gather information about the fertility levels and changes in them, infant and child mortality, family plan-ning, and maternal and infant health at the national level. Results Overweight/obesity for height was 8.6% and 6.6% for age. Overweight/obesity problems are mostly observed in the West and are higher in urban areas. Overweight/obesity decreases with increasing age. There is a positive correlation between overweight/obesity and maternal educational level. As the household welfare level increases, overweight/obesity increases in pre-school children. Female children are at higher risk of overweight/obesity than males. As birth order increases, overweight/obesity decreases. Children living in other regions have overweight/obesity problems more than the pre-school children living in the East. Conclusions This study speculates that obesity appears to be a major problem among pre-school children in Turkey. Based on the findings, the current situation of overweight/obesity among pre-school children is so close to many developing and developed countries, whose obesity levels are a greater concern. This finding demonstrates that effective interventions of obesity should begin as early as infancy in Turkey, as it is a developing country.

Journal of Iron and Steel Research International 2011年第8期18卷 65-72页

作者： fatih Hayat Hüseyin Uzun Metallurgy and Materials Engineering Department Engineering FacultyKarabuk University Metallurgy Education Department Technical Education FacultySakarya University

Grade A （GA） and high strength steel DH36 ship steels possessing different chemical compositions were used, and strength properties of GA steel and DH36 steel were compared. Additionally, 4 types of dual phase （DP） steels with different martensite volume fractions （MVFs） were produced from GA steel by means of heat treatment and they were compared with other steels through conducting mierostructure, microhardness, tensile and impact tests. The fracture surfaces of specimens （DH36, GA and DP steels） exposed to tensile and Charpy impact tests were investigated by scanning electron microscope. Furthermore, it was found that the specimens quenched from 800 and 900℃ had better strength than DH36 steel. The tensile test results indicated that the tensile strength of DP steel water quenched from 900℃ was 3 times that of GA steel and twice that of DH36 steel.

Prediction of Excess Air Factor in Automatic Feed Coal Burners by Processing of Flame Images

引用

Chinese Journal of Mechanical Engineering 2017年第3期30卷 722-731页

作者： Muhammed fatih TALU Cem ONAT Mahmut DASKIN computer engineering department inonu university44280 MalatyaTurkey mechanical engineering department inonu university44280 MalatyaTurkey

In this study, the relationship between the visual information gathered from the flame images and the excess air factor 2 in coal burners is investigated. In conventional coal burners the excess air factor 2. can be obtained using very expensive air measurement instruments. The proposed method to predict ） for a specific time in the coal burners consists of three distinct and consecutive stages; a） online flame images acquisition using a CCD camera, b） extrac- tion meaningful information （flame intensity and bright- ness）from flame images, and c） learning these information （image features） with ANNs and estimate 2. Six different feature extraction methods have been used： CDF of Blue Channel, Co-Occurrence Matrix, L-Frobenius Norms, Radiant Energy Signal （RES）, PCA and Wavelet. When compared prediction results, it has seen that the use of co- occurrence matrix with ANNs has the best performance （RMSE = 0.07） in terms of accuracy. The results show that the proposed predicting system using flame images can be preferred instead of using expensive devices to measure excess air factor in during combustion.

A fast and efficient coordinated vehicle-to-grid discharging control scheme for peak shaving in power distribution system

引用

Journal of Modern Power Systems and Clean Energy 2018年第3期6卷 555-566页

作者： Nuh ERDOGAN fatih ERDEN Mithat KISACIKOGLU Department of Electrical Engineering University of Texas at Arlington Department of Electrical and Electronics Engineering Bilkent University Department of Electrical and Computer Engineering University of Alabama

This study focuses on the potential role of plugin electric vehicles(PEVs) as a distributed energy storage unit to provide peak demand minimization in power distribution systems. Vehicle-to-grid(V2 G) power and currently available information transfer technology enables utility companies to use this stored energy. The V2 G process is first formulated as an optimal control ***, a two-stage V2 G discharging control scheme is proposed. In the first stage, a desired level for peak shaving and duration for V2 G service are determined off-line based on forecasted loading profile and PEV mobility model. In the second stage, the discharging rates of PEVs are dynamically adjusted in real time by considering the actual grid load and the characteristics of PEVs connected to the grid. The optimal and proposed V2 G algorithms are tested using a real residential distribution transformer and PEV mobility data collected from field with different battery and charger ratings for heuristic user case scenarios. The peak shaving performance is assessed in terms of peak shaving index and peak load reduction. Proposed solution is shown to be competitive with the optimal solution while avoiding high computational loads. The impact of the V2 G management strategy on the system loading at night is also analyzed by implementing an off-line charging scheduling algorithm.

Poly[2-（4-chlorophenyl）-l,3-dioxolan-4-yl]methyl acrylate, poly（CPhDMA）, was synthesized with radical polymerization process using 2,2＇-azobisisobutyronitrile as radical initiator in 1,4-dioxane at 60℃. The structure of poly（CPhDMA） was confirmed by means of UV-Vis, FT-IR, 1H-NMR, and 13C-NMR spectral techniques. The molecular weight distribution values of the polymer were determined with gel permeation chromatography （GPC）. The number-average molecular weight （Mn）, weight-average molecular weight （Mw） and polydispersity index （PDI） values of poly（CPhDMA） were determined to be 10300, 21600 and 2.097, respectively. The thermal degradation kinetics of the polymer was investigated by using TG/DTG-DTA and DSC analyses at different heating rates in dynamic nitrogen atmosphere. The apparent activation energy values obtained by Flynn-Wall-Ozawa and Friedman methods were found to be 91.68 and 85.23 kJ mo1-1, respectively, for thermal decomposition of poly（CPhDMA）. Also, the thermal degradation activation energy value of poly（CPhDMA） was calculated by using the Kissinger method based on the DTG, DTA and DSC data. Then the mechanism function of it was determined by master plots method. Finally, electrical and optical properties of poly（CPhDMA） were determined by four-point probe and UV-Vis techniques, respectively.
