Wind-induced circulations of the Black Sea
(Pergamon-Elsevier Science LTD, 1995)A two-dimensional single layer hydrodynamic model of the Black Sea is constructed in which currents are driven by the forcing effect of the wind. An explicit finite difference scheme was used where the equations were ... -
Fluoride injury in some regional plants grown in the vicinity of Bozuyuk ceramic factories and fumigation chamber studies
(1996)Within the scope of this study, the culture plants barley (TOKAK) and wheat (GEREK 79) species grown in the agricultural fields nearby Akpinar Region in the vicinity of Bozuyuk Ceramic factories, were planted in flowerpots. ... -
Electron microscopy studies of petroleum contaminated marine clay
(IOP Publishing LTD, 1997)The effects of crude oil on physico-chemical and microstructure properties of laboratory prepared marine clays were studied. Crude oil significantly influenced clay microstructure and physico-chemical properties such as ... -
Optimum conditions for the precipitation of chitosan oligomers with DP 5-7 in concentrated hydrochloric acid at low temperature
(Elsevier Sci LTD, 1999)Chitosan was partially hydrolysed with 35% hydrochloric acid for 2 h at 80 degrees C and the hydrolysate stored at - 20 degrees C after dilution with water to precipitate higher molecular weight (MW) chitosan oligomers. ... -
Identification of the different sources of chlorides in streams by regression analysis using chloride-discharge relationships
(Water Environment Federation, 1999)Chloride-discharge relationships at several stations on Turkish streams are investigated, both qualitatively and quantitatively, to identify natural and anthropogenic sources of chloride. Simple expressions are used to ... -
Trikloroetilenin elementel demir üzerinde indirgenmesi ve yeraltında suya doygun olmayan katmanlarda uygulanışı
(2001)Bu çalışmada, uçucu ve klorlu organik çözücü maddelerin yeraltında suya doygun olmayan bölgelere yayılmaları sonucu oluşan kirliliğin kontrolünde elementel demirin (Fe°) kullanımı önerilmiştir. Böylelikle reaktif bariyer ... -
Comparison of methods for estimating carbonaceous BOD parameters
(Selper LTD, Publications Div, 2001)The performance of seven different methods (Differential, Fujimoto, Thomas, Graphical, Integral, Log-Difference, and Nonlinear Regression) for estimating first-stage, carbonaceous biochemical oxygen demand (CBOD), curve ... -
Impacts of a chronic high-level exposure to HF on Nicotiana tabacum L.: Morphological and physiological changes
(Inst Lebensmitteltechnologie Analytische Chemie, 2002)A long-term plant-exposure study was conducted to quantify the observed damages of Nicotiana tabacum L. cv. St. Karabaglar 6265, caused by fluoride-rich atmosphere in the field. Individual effects of hydrogen fluoride on ... -
Fluoride emission factors
(2002)An attempt was made to generate fluoride emission factor data for a fast- and single-fired ceramic floor-tile kiln located in Turkey. Desired emission factors were calculated from stack-gas measurements and mass-balance ... -
The removal of salinity from produced formation water by conventional and electrochemical methods
(Inst Lebensmitteltechnologie Analytische Chemie, 2002)The produced formation water (PFW) which is extracted together with the petroleum is highly saline. In this study the removal of the ions causing salinity, namely Na+, Ca2+, Mg2+, Cl-, SO42- and HCO3- has been investigated. ... -
Electroadsorption of acilan blau dye from textile effluents by using activated carbon-perlite mixtures
(Water Environment Federation, 2002)The feasibility of the removal of dye stuffs from textile effluents by electroadsorption has been investigated. An activated carbon-perlite mixture with a ratio of 8:1 for bipolarity has been used as the adsorbent. ... -
Removal of nitrate from aqueous solutions by electrodialysis
(2002)In this work the removal of the nitrate from water was carried out by electrodialysis. In the experiments the effect of the applied voltage, pH value, initial nitrate concentration and duration of treatment on the removal ... -
Statistical analysis of water quality trends: An application to the Porsuk Stream
(2002)Bu çalışmada, su kalitesi zaman serilerinde eğilimlerin saptanması için parametrik olmayan eğilim analizi uygulanmıştır. Analizler için, diğer istatistiksel testlerin yanısıra, Mevsimsel Kendall Eğilim Testi kullanılmıştır. ... -
Laboratory development and field evaluation of a new diffusive sampler to collect nitrogen oxides in the ambient air
(Springer-Verlag Berlin, 2002)Diffusive samplers for the determination of NOx and NO2 based on collection on a coated carbon paper filter have been developed. NO is first oxidized to NO2 and then collected on the reactive surface. When NO2 and NOx ... -
Validation and use of a new diffusive sampler for ozone assessment in the Lazio Region, Italy
(2002)To monitor the effect of control measures for ozone it is desirable to map the concentrations for this pollutant at regional level, in agreement with the aims of the European Framework Directive on ambient air quality ... -
Modeling the effects of diffuse nitrogen sources on a small stream using QUAL2EU
(Wit Press, 2003)In this study, a regulated stream draining the Seydi Suyu watershed where intensive agriculture is practiced has been modeled with respect to nitrogen. Nitrogen is added to the stream from diffuse sources due to agricultural ... -
