The present study was undertaken as part of the first application and evaluation of the BREF (Best Available Techniques; BAT Reference Document) Textile Document within the context of the European Union's Integrated Pollution Prevention and Control (IPPC) Directive to a large scale textile mill in Turkey. The BAT requirements for the denim manufacturing textile mill were selected in cooperation with the factory management. Detailed mass balance calculations were conducted to evaluate the overall effect of the selected BAT options. The initial findings indicated that the adoption of the selected BAT options resulted in considerable savings in water and energy consumption in the mill. Besides the installation of flow meters and use of semi-counter current rinsing in the most water-intensive processes, minimization of wash waters in the water softening plant, reuse of the concentrate stream from the reverse osmosis plant and compressor cooling waters provided a 29.5% reduction in the total specific water consumption of the mill, reaching the lower limits suggested by the BREF Textile Document. In terms of energy consumption, use of waste heat from finishing wastewater streams in heating up the wash waters, heat insulation and maintenance applications in addition to BAT measures taken for water minimization reduced specific energy consumption by 9% achieving the limits set by the BREF Textile Document.


Evaluating microemulsions for purification of beta-galactosidase from Kluyveromyces lactis
Mazı, Bekir Gökçen; Hamamcı, Haluk; Department of Food Engineering (2010)
In this study, we evaluated the potential of water-in-oil microemulsions for the separation of beta-galactosidase (lactase) from other proteins. The ability of beta-galactosidase to break down the milk carbohydrate lactose gives the enzyme considerable commercial importance. The extent of solubilization of a commercial Kluyveromyces lactis preparation of beta-galactosidase into microemulsion droplets formed from 200 mM bis (2-ethylhexyl) sodium sulfosuccinate (AOT) in isooctane was measured as a function of...
Use of cinematherapy in dealing with relationship problems
Egeci, I. Sine; Gençöz, Faruk (2017-04-01)
The main goal of this study was to examine propositions regarding the application procedures of cinematherapy. It compared the contributions to create therapeutic change of viewing (watching a movie with therapeutic aims) and discussion steps (discussing movies with therapeutic aims). Twenty-eight sessions were held with 6 participants seeking professional help for relationship problems (e.g. frequent conflicts, dissatisfaction, sexual problems). Content analyses of questionnaire responses and therapy sessi...
Accuracy of two different voxel sizes for presurgical evaluation of mandibular osteotomy
Bozkurt, P.; Kurt, M.H.; Kolsuz, M.E.; Orhan, K.; Cömert, A.; Vardar Acar, Ceren (2020-04-01)
The aim of this study was to compare the accuracy of two different voxel resolutions for the preoperative assessment of mandibular osteotomies. The study was conducted on 37 dry adult human mandibles. To obtain measurement standardization, heated gutta-percha cones were placed on the dry mandibles to mark 20 anatomical points. These cones were used for all measurement groups. Cone beam computerized tomography (CBCT) scans of the mandibles were made using 0.200 mm(3) and 0.400 mm(3) voxel sizes (Planmeca Pro...
Review of Studies Related to Pedagogical Content Knowledge in the Context of Science Teacher Education: Turkish Case
Aydin, Sevgi; Boz, Yezdan (2012-12-01)
As a review study, the present study was carried out in order to introduce PCK construct to researchers and evaluate which aspects of PCK were studied in our country, and, finally, make recommendations in light of the analysis of the studies for further research. For this purpose, ERIC database, YOK (Higher Education Council) database were searched by using "Pedagogical Content Knowledge" as keyword. Moreover, journals published in Turkey and which are possible to be reached electronically were searched usi...
Design of a new equipment for sesame seed dehulling
Güngör, Uğraş; Esin, Ali; Department of Food Engineering (2004)
In this study, new methods and processing equipments for sesame dehulling were investigated. First, water absorption of sesame seed was studied at 20, 30, and 40°C. The data could be modeled using Peleg equation where it was found that the constant k1 was inversely related to temperature but the effect of temperature on k2 was negligible. In the second phase of the work a lab scale continuous screw conveyor as dehuller and two equipments, (1) fluidized bed dryer and (2) hull separator to function as agitato...
