Temporal variation of dissolved oxygen in a mountain stream plunge pool: An example from northern Turkey

Kucukali S. | Cokgor S. | Kartal B.

Conference Object | 2007 | Examining the Confluence of Environmental and Water Concerns - Proceedings of the World Environmental and Water Resources Congress 2006

In this paper, a forested-mountain stream (Harmankaya) with a drainage basin about 12 km 2 located in Zonguldak (41°N-31°E) on the NW of Turkey has been studied associated with its plunge pools during April and November 2004. In the stream, 22 plunge pools were detected and plunge pools drop heights had a variation of 0.7-20 m, whereas average pool depths had a range of 0.53-1.59 m. In a selected pool, the variation of dissolved oxygen (DO) concentration and temperature (T w) through the pool depth have been investigated at different time intervals. The data indicated the seasonal dependence of dissolved oxygen concentration in the . . .plunge pool related with the water temperature and when the pool exposed to sunlight thermal stratification occurred through the pool depth. Besides, in all seasons DO levels had a downward trend from pool surface to pool bottom. Riparian vegetation significance has been emphasized in terms of the regulating the temperature and dissolved oxygen levels of a pool especially during the summer. Moreover, pool well-shaded site had relatively low degree of thermal stratification compared to waterfall impact site because of the canopy cover. © 2006 ASCE Daha fazlası Daha az

Article | 2016 | ANATOLIAN JOURNAL OF CARDIOLOGY16 ( 8 ) , pp.554 - 562

Objective: To analyze health-related cost of heart failure (HF) and to evaluate health-related source utilization aiming to provide data on the economic burden of HF in actual clinical practice in Turkey. Methods: The study used the Delphi process of seeking expert consensus of opinion including 11 cardiologists who are experienced in HF. The standardized questionnaire comprised items to reflect the opinion of the expert panelists on the distribution of the HF patients in terms of demographic and clinical characteristics and background disease states. Costs related to out-patient follow-up, in-patient follow-up, medications, and oth . . .er therapies were also evaluated. Results: 34.1% of the HF patients were in the age range of 60-69 years, and 62.3% were males. Coronary heart disease was the leading cause of HF (59.6%); 63.6% of the HF patients had reduced ejection fraction (rEF) and 42.3% were in New York Heart Association (NYHA)-II class. Approximately 75 % of the patients were followed up by a cardiology unit. The total annual visit number was estimated as 3.41. Approximately 32% of HF patients were hospitalized 1.64 times a year, for an average of 6.77 days each time. The total annual costs of all HF patients and HF-rEF patients were estimated as 1.537 TL and as 2.141 TL, respectively. Conclusion: The analysis demonstrating the magnitude of the economic impact of HF management on Turkey's healthcare system may help facilitate health and social policy interventions to improve the prevention and treatment of HF Daha fazlası Daha az

Public participation in forestry in Turkey

Atmis, Erdogan | Ozden, Sezgin | Lise, Wietze

Article | 2007 | ECOLOGICAL ECONOMICS62 ( 2 ) , pp.352 - 359

Recently public participation in forestry has been seriously considered in Turkey. Participation is however quite a challenge for a country with a long tradition of top-down management and a strong bottom-up dependence on public provisioning. in such a setting, it may not be surprising that the experiences with public participation in forestry in Turkey are mixed. There are some positive initiatives like the creation of farmer's cooperatives and NGOs, but their role is quite limited and small of scale. This paper is bringing together different views based on existing studies in Turkish related to Turkey's experience with implementin . . .g public participation in forestry. (c) 2006 Elsevier B.V.

Demi·Rhan K. | Onur İNce F.H.

Review | 2018 | Amme Idaresi Dergisi51 ( 3 ) , pp.61 - 87

Civil society organizations have some public roles. These roles are getting in contact with local, regional and global public actors, finding sources, affecting public opinion, improving civic culture, and leading decision making processes. Internet and social media platforms may contribute to civil society organizations realizing their public roles and improving their institutional potentials. Civil society organizations should have access to the information technologies and should develop a specific strategy towards the use of information technologies. This research analyzes the access level of civil society organizations to infor . . .mation technologies, the usage level of information technologies in the activities of organizations, and organizations’ approach to the use of these technologies. © 2018 TURKIYE ORTADOGU AMME IDARES IENSTITUSU.

Article | 2018 | Turkish Journal of Biochemistry43 ( 4 ) , pp.435 - 446

Objective: Cupressaceae pollen has commonly been reported to be an important aeroallergen and causal factor of spring, autumn and winter pollinosis in many countries. The aim of this study was to compare of the structure and allergenic protein content of Cupressus arizonica Greene., Cupressus sempervirens L. and Juniperus oxycedrus L. pollen in detail and contribute to Cupressaceae pollen allergen diagnosis and therapy studies in Turkey. Methods: The pollen structure were examined by LM and SEM. Pollen protein content was investigated by Bradford protein assay, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), We . . .stern blot analysis and two-dimensional polyacrylamide gel electrophoresis (2DE PAGE), respectively. Pectate lyase (PL) enzyme activities were compared. Immunoblotting was carried out by using extracts of the three taxa pollen collected from Turkey. Results: All three taxa was found very similar in terms of pollen morphology however, intine thickness was prominently different. Cupressus arizonica pollen extracts showed the lowest PL activity. Five sera specific IgE of all allergic subjects showed reaction with only C. arizonica pollen extracts. Conclusions: As a conclusion, the pollen structure, protein function or protein structure and isoforms of allergens could affects allergenic properties of the pollen. This study also may help to improve the Cupressaceae pollen allergen diagnosis and therapy. © 2018 Turkish Biochemistry Society. All rights reserved Daha fazlası Daha az

Genetic variability among Turkish pop, flint and dent corn (Zea mays L. spp. mays) races: Morphological and agronomic traits

Ilarslan R. | Kaya Z. | Kandemir I. | Bretting P.K.

Article | 2002 | Euphytica128 ( 2 ) , pp.173 - 182

32 Turkish corn accessions representing different climatic, geographic and topographic areas in Turkey were identified. Genetic variation and its pattern in three corn races (pop, flint and dent) included 32 accessions were investigated using 25 morphological and agronomic traits. Vegetative, ear and kernel related traits were significantly varied both among races and accessions within races. Variance component due to races and accessions within race were statistically significant, but the variance components due to accessions were generally made up large component of total variance and ranged from 17.17% in kernel length to 82.75% . . .in tassel length. There were also strong and mostly positive correlations between studied agronomic traits as well as between agronomic traits and isoenzyme loci. These correlations were explained by the traditional farming practices and enzyme specificity with flint accessions since the enzyme systems such as Alcohol dehydrogenase (locus 1), Malate dehydrogenase enzyme (loci 2-3) and 6-phospho-gluconate dehydrogenase (locus-1) are generally considered to be the characteristics of flint corn race. Canonical discriminant function analysis with twenty-five morphological and agronomic traits revealed that first two canonical discriminant variables explained 68% of total variation among accessions. Two Canonical variables, in which kernel related traits were heavily weighted, correctly classify the three corn races - indicating that Turkish corn accessions maintained their racial characteristics with agronomic and morphological traits Daha fazlası Daha az

Fuat Dündar and the Deportation of the Greeks

Efiloglu A.

Review | 2014 | Middle East Critique23 ( 1 ) , pp.89 - 106

A review of the controversial book by Turkish historian Fuat Dündar, Modern Türkiye'nin Şifresi, İttihat ve Terakki'nin Etnisite Mühendisligi [The Code of Modern Turkey: The Committee of Union and Progress' Ethnic Engineering], published in 2008. The main thesis of the book is that the fundamental aim of Committee of Union and Progress (CUP) government was to Turkify Anatolia through the deportation and re-settlement of its non-Turkish population. Dündar deals primarily with the deportation of the Armenians. He believes that the Unionists had been exerting their utmost effort toward Turkifying Anatolia since 1913.1 The CUP master pl . . .an was to deport the Armenians, thus cleansing them from Anatolia. Dündar claims that in 1915 the CUP even found it necessary to massacre the Armenians in some regions.2 However, this review examines only the section of his book on the deportation of the Greeks, a topic that does not garner as much attention as the Armenian deportations. This review attempts to show how Dündar addressed this topic, how he used the documents, and how well he managed to deliver on his aim of interpreting the documents in a way that sheds new light on the deportations of Greeks. He views the deportation and resettlement of the Greeks as a development that came about after the beginning of World War I, when the CUP entered into an alliance with Germany, and references documents that he studied in the Ottoman archives to support his argument. © 2014 © 2014 Editors of Middle East Critique Daha fazlası Daha az

Geniş M. | Sakız U. | Çolak Aydıner B.

Article | 2017 | Bulletin of Engineering Geology and the Environment76 ( 4 ) , pp.1237 - 1248

The stability of rock slopes is an important area of interest in civil and mining engineering. This study investigated rockfall occurring around the Gökgöl tunnel along the Zonguldak-Ankara roadway. Extensive field studies, including determination of geological description of the rock mass, scan-line surveys on discontinuities, identification of slope profiles, measurement of actual fallen block dimensions, and sampling procedures, were carried out. The study area and its surroundings are part of a Lower Carboniferous limestone formation. The assessments based on field studies indicated that two joint sets and a bedding plane were t . . .he main types of discontinuity. Two slope profiles were then created by considering the most frequently encountered rock fall events. The present study aimed to investigate the rockfall potential in this area by means of numerical analyses. For this purpose, RocFall software based on the lumped-mass method was utilized. Based on these analyses, traffic safety is threatened by potential rockfall. In Case I, a 30 % portion of the falling blocks reached the side of the main road, while about 70 % of them remained on the slope. However, falling blocks reached the end of the road in Case II. The study area requires some protection measures, such as the construction of retaining barriers and steel mesh to hold small size rock blocks. As a result, barrier heights to hold falling blocks were calculated as 0.5 m and 4 m for Case I and Case II, respectively. Barrier heights sufficient to hold falling rocks were determined using numerical analysis. In Case II, from such analyses, the energy required for a protection barrier for 1000 kg was found to be 200 kJ. © 2016, Springer-Verlag Berlin Heidelberg Daha fazlası Daha az

Meteorological variations of PM2.5/PM10 concentrations and particle-associated polycyclic aromatic hydrocarbons in the atmospheric environment of Zonguldak, Turkey

Akyüz M. | Çabuk H.

Article | 2009 | Journal of Hazardous Materials170 ( 1 ) , pp.13 - 21

Airborne particulate matter (PM2.5 and PM10) concentrations were measured in Zonguldak, Turkey from January to December 2007, using dichotomous Partisol 2025 sampler. Collected particulate matter was analyzed for 14 selected polycyclic aromatic hydrocarbons (PAHs) by high-performance liquid chromatography with fluorescence detection (HPLC-FL). The seasonal variations of PM2.5 and PM10 concentrations were investigated together with their relationships with meteorological parameters. The maximum daily concentrations of PM2.5 and PM10 reached 83.3 µg m-3 and 116.7 µg m-3 in winter, whereas in summer, they reached 32.4 µg m-3 and 66.7 µ . . .g m-3, respectively. Total concentration of PM10-associated PAHs reached 492.4 ng m-3 in winter and 26.0 ng m-3 in summer times. The multiple regression analysis was performed to predict total PM2.5- and PM10-associated PAHs and benzo(a)pyrene-equivalent (BaPE) concentrations with respect to meteorological parameters and particulate mass concentrations with the determination coefficients (R2) of 0.811, 0.805 and 0.778, respectively. The measured mean values of concentrations of total PM2.5- and PM10-associated PAHs were found to be 88.4 ng m-3 and 93.7 ng m-3 while their predicted mean values were found to be 92.5 ng m-3 and 98.2 ng m-3, respectively. In addition, observed and predicted mean concentration values of PM2.5-BaPE were found to be 14.1 ng m-3 and 14.6 ng m-3. The close annual mean concentrations of measured and predicted total particulate related PAHs imply that the models can be reliably used for future predictions of particulate related PAHs in urban atmospheres especially where fossil fuels are mainly used for heating. © 2009 Elsevier B.V.
