Thermal Energy Investments in Catalagzi Region (Zonguldak)

Celikoglu, Saban

Makale | 2016 | MARMARA GEOGRAPHICAL REVIEW ( 33 ) , pp.510 - 533

As the most prominent instrument for power in modern world, energy is of a vital importance for the development of countries. Industrial development in Turkey, which is one of the developing countries, undergoes increase in energy demand due to rising levels of life standards and tehcnological developments. This rapid demand growth brings about problems such as external energy dependence and deficit in our country, which disposes of limited energy resources. Approximately half of electricity generation in Turkey is obtained by natural gas. Additionally, natural gas is important as an implement for home heating. According to EMRA (En . . .ergy Market Regulatory Authority) data, nearly 85% of the natural gas has been supplied from 3 countries. Building thermal reactors which working with stone coal and lignite, is considered important in order to reduce the impact of a probable difficulty in energy supply. Catalagzi Region in Zonguldak Province is also one of the areas which glare as investment grade. Two active thermal reactors in Catalagzi Region with installed power of 1690 mW, are producing electricity of 12,5million mW on annual basis. With the inclusion of a third thermal reactor planned for the autumn of 2016, electricity generation grade is expected to reach almost 20 million mW on annual basis with an installed power of 3090 mW. In this study it is aimed to emphasize on the partake of Catalagzi Region within electricity generation in Turkey, and to remark the sustainable energy production as well as measures taken for improving the life quality of locals Daha fazlası Daha az

Previous reports of plant regeneration of natural tetraploid T. pratense L. 'Elci' could be realized only through the apical meristem calli. In order to proceed to the production stage, other regeneration methods need to be tried. Aseptic seedlings were used for the production of somatic embryos through various 2,4-D and kinetin trials. Nonuniform external callus cells with translucent cytoplasm were observed in various developmental stages of somatic embryos. Beneath these cells, there were uniformly aligned, dark-stained embryo cells with dense cytoplasm. Despite the similar developmental stages and cell characteristics of zygotic . . . and somatic embryos, the walls of somatic embryo cells revealed a highly wavy pattern. The nucleus generally contained only one nucleolus, which was spherical, dark stained, and electron-dense. Electron-dense droplets were seen in vacuoles. The cytoplasm consisted of starch-containing amyloplasts, mitochondria, plastids, ribosomes, endoplasmic reticulum, dictyosomes, lipid, and protein bodies. In some of the somatic embryos at the globular and heart stages, vacuole or electron-translucent zones were observed in the nucleolus. Additionally, a few embryo degenerations were recorded during developmental stages of the zygotic embryo. For the first time, the somatic embryos of natural tetraploid T. pratense were produced from hypocotyl (85%), cotyledon (75%), and apical meristem (60%) explants in 0.3 mg/L 2,4-D and 2 mg/L kinetin-containing MS medium. Our study developed an effective and efficient in vitro production method for using natural tetraploid T. pratense in biotechnological studies Daha fazlası Daha az

Makale | 2016 | Journal of Spatial Science61 ( 1 ) , pp.119 - 131

Since 2007, the revolutionary X-band synthetic aperture radar (SAR) satellites Cosmo-SkyMed (CSK) and TerraSAR-X (TSX) have been collecting high-resolution images that are convenient for digital surface model (DSM) acquisition by the interferometric SAR (InSAR) technique. In this study, the potential of DSMs derived from CSK and TSX high-resolution spotlight (HS) images is thoroughly analysed regarding the basic accuracy metrics absolute vertical accuracy (AVA) and relative vertical accuracy (RVA). Utilising convenient InSAR pairs, 2 m gridded DSMs are generated in Istanbul and validated with model-based comparisons using an actual . . .airborne laser scanning (ALS) DSM. Results show that CSK and TSX DSMs are compatible in open, built-up and forest land forms. The AVAs are between 8 m and 10 m based on standard deviation of height discrepancies against the ALS model. The RVAs, calculated by the coherence of neighbouring pixels for each DSM, are superior to AVAs for both CSK and TSX. © 2016 Mapping Sciences Institute, Australia and Surveying and Spatial Sciences Institute Daha fazlası Daha az

Entropy generation analysis of a microchannel-condenser for use in a vapor compression refrigeration cycle

Turkakar, Goker | Okutucu-Ozyurt, Tuba | Kandlikar, Satish G.


Dimensionless entropy generation number in the microchannel condenser of a vapor compression refrigeration cycle is investigated. An air cooled, brazed aluminum parallel flow heat exchanger is considered as the condenser with R-134a as the refrigerant. While the effects of the fin pitch, fin height, louver angle and the air mass flow rate are investigated for the air side, the effect of the channel diameter is examined for the refrigerant side. The analysis is performed segment by segment for the superheated, two phase and subcooled regions using well-established empirical correlations. A mapping study is presented for the variation . . . of entropy generation number with the mentioned parameters. The optimum air mass flow rate interval is found to be between 0.055 and 0.1kgs(-1) for a given fin pitch interval of 1-1.6 mm. This range is within the operating limits of air fans in the market for this size. In this operating range, the optimal dimensions giving the minimum entropy generation numbers are presented. The entropy generation number distribution is given based on the pressure drop, heat transfer or the refrigerant state in the heat exchanger considering superheated, two phase, and subcooled regions. The entropy generation number due to pressure drop on the air side becomes dominant after a mass flow rate around 0.08kgs(-1). Hence, an optimum air mass flow rate generating the minimum entropy generation number is sought for different sizes of the condenser. The condenser length is variable in the range of 84.3-80.6 mm for the mentioned optimal air mass flow rate interval. The condenser height changes depending on desired operational conditions, and it is determined to be 112.5 mm for the fixed values given in the study. The study is unique in the literature in pursuing an entropy generation number mapping study for microchannel two-phase flow in air cooled heat exchangers. (C) 2016 Elsevier Ltd and IIR.

Alper, Baris | Erdogan, Baris | Erdogan, Mehmet Ozgur | Bozan, Korkut | Can, Andmurat

Makale | 2016 | MEDIATORS OF INFLAMMATION , pp.71 - 83

We investigated the associations of injury severity scores (ISSs) with the mean platelet volume, the serum levels of two interleukins (IL1 beta and IL6), and the serum levels of tumour necrosis factor-alpha (TNF alpha) and C-reactive protein (CRP). We sought to identify biochemical parameters that could be used as components of a new biochemical parameter-based ISS system. The levels of CRP, TNF alpha, IL1 beta, and IL6 differed significantly (all p values < 0.05) between severely injured patients and controls. The mean platelet volume (MPV) did not correlate with the ISSs (p > 0.05). The TNF alpha and IL6 levels were useful for det . . .ermining the severity of injury, and the CRP level was elevated in all trauma patients but did not correlate with the ISS. The IL1 beta level was higher in the study group but did not increase as the ISS increased. IL6 and TNF alpha levels were higher in the study group and increased as the ISS increased. We found no significant difference between the trauma group and healthy individuals in terms of MPV values. IL6 and TNF alpha levels can be used to assess trauma severity. However, neither the MPV nor the CRP or IL1 beta level is useful for this purpose Daha fazlası Daha az

Bu makalede PISA Türkiye verisi kullanılarak yazılan akademik makalelerde PISA verisinin yöntembilimsel olarak ne kadar doğru kullanılabildiği sınanmaktadır. ISI Web of Knowledge, Scopus ve ULAKBİM dizinlerinde PISA Türkiye verileri/sonuçları üzerine yazılmış 97 makaleye ulaşılmıştır. Bu makalelerin sadece 46'sında PISA Türkiye verisi kullanılarak özgün bir analiz yapıldığı tespit edilmiştir. Yöntembilimsel olarak incelenen 46 makalenin büyük çoğunluğunda ise örneklem ağırlıkları, olası değerler ve analizler için kullanılan yazılım gibi özelliklerden bahsedilmediği görülmüştür. Sadece 5 makalede örneklem ağırlıklarının doğru kullanı . . .mı rapor edilirken, olası değerler de sadece 10 makalede istatistiksel olarak uygun şekillerde kullanılmıştır. Bu sonuçlar PISA Türkiye verilerinin akademik yazında kullanımının çok sınırlı olduğunu göstermektedir. Dahası, PISA Türkiye verisi ile özgün analizler yapan makalelerin de büyük çoğunluğunda yöntembilimsel gerekliliklere uyulmadığını ve yapılan analizlerin büyük çoğunluğunun bu haliyle güvenilir olmaktan uzak olduğunu söylemek mümkündür. Bu haliyle PISA Türkiye verilerinin Türkiye'de eğitim politikalarına yön verme potansiyelinden hayli uzakta olduğunu söylenebilir This article methodologically reviews the scientific articles based on PISA Turkey data. 97 articles were reached using ISI Web of Knowledge, Scopus and ULAKBIM indices. Among these articles, only 46 are found to have employed original analysis of PISA Turkey data. Moreover, most of the 46 reviewed articles are failed to report methodological issues such as sampling weights, the use of plausible values and the software employed in the analyses. Only 5 articles are found to use and report sampling weights properly, only 10 used plausible values in a methodologically acceptable way. These results show that the use of PISA Turkey data in scientific articles is very limited. Moreover, most of the articles that employ original analyses with PISA Turkey data fail to meet methodological necessities. Thus, their results are far from being reliable. In this manner, it is hard to claim that the potential of PISA Turkey data to guide education policies in Turkey can be realized Daha fazlası Daha az

In this study, it was intended to evaluate the effect of childhood trauma on the anger status of university students. A total of 323 students who were studying in a University, Department of Nursing were included in this cross-sectional study. Data were collected by using Descriptive Information Form, Childhood Trauma Questionnaire and Trait Anger and Anger Expression Scale. Data were analyzed by using numerical and percentage values, Mann-Whitney U test, Kruskal-Wallis test and Spearman Correlation Analysis. It was f ound thatmean total score of Childhood Traumatic Events Scale was 102.26, mean score of emotional abuse and neglect . . .was 59.96, mean score of physical abuse was 33.18 and mean score of sexual abuse was 9.11. Mean trait anger score of students was found to be 22.67; and mean scores of anger-out, anger-in and anger control, that are the subdimensions of anger expression styles, were found to be 17.16, 16.58 and 21.57, respectively. When the relationship between childhood traumatic events of the students and their trait anger and the forms of anger expression was examined, it was determined that their trait anger levels increased (p=0.000, r=0.203), and they reflected their anger more (p=0.000, r=0.217) as their exposure to traumatic events increased. According to the results of this study,it was found that mean score of Childhood Traumatic Events Scale was was high. © GATA Daha fazlası Daha az
