Oltu-stone (Jet Stone), also known as black amber, is a fossilized, organic, and natural material formed by the transformation of certain trees under high pressure. It is called Oltu-stone because its occurrences are primarily located in the Oltu district of Erzurum. Generally, it is mined by small miners from nearby villages using rather primitive methods. After a rough sorting at the mine site, Oltu-stone is mainly used in manufacturing worry beads, tespih, and to a lesser extent, certain ornamental goods...
Determination of optimum hazelnut roasting conditions
Saklar, S; Katnas, S; Ungan, S (2001-03-01)
The objective of this study was to test the hypothesis that the roasting conditions used for hazelnuts, such as the air temperature, air velocity and roasting time (independent variables), could be optimized by using Response Surface Methodology. Effects of independent variables on sensory and physical characteristics were determined. A consumer test was used to determine the acceptable samples. Very dark and very light roasted samples, corresponding to 165 degreesC, 3 m/s, 25 min and 125 degreesC, 1 m/s, 1...
Determination of optimum values for voltage setpoints of power stations in Turkey
Elma, İsmail; Güven, Ali Nezih; Tör, Osman Bülent; Department of Electrical and Electronics Engineering (2014)
Voltage control is performed in three hierarchical levels in Turkish power system: primary, secondary and tertiary voltage control. Primary and secondary voltage controls are defined as the regulation of the voltage at the generator terminal and at the high voltage busbar of the power plant according to the pre-determined setpoints. The determination of the voltage setpoints for the power plants, which is defined as the tertiary voltage control, is performed by the operators in National and Regional Load Di...
Determination of optimum overall slope angle for an open pit iron mine
Akdağ, Selahattin; Başarır, Hakan; Department of Mining Engineering (2015)
Currently, vast majority of the mineral extraction is conducted by open pit mining operations. With the improvements in mining industry, mines have become progressively deeper leading to slope stability problems. Therefore, slope stability assessment has gained more significance for geotechnical engineering. Moreover, deepening the open pit mines has revealed the necessity of designing optimized slopes with regard to the economic viability. Steepening the ultimate slope of an open pit as much as possible mi...
Determination of environmental quality standard -based discharge limits and mixing zones for tersakan sub-basin of Yeşilirmak river
Çelebi, Sarp; Ünlü, Kahraman; Department of Environmental Engineering (2019)
The control of point source discharges to rivers has become more elaborate since the establishment of environmental quality standards (EQSs). Many countries including Turkey have set EQS values for various contaminants of concern (CoCs) i.e. maximum concentration limits that would not cause detrimental effects on the health of the human-beings or the overall environment. One important challenge of achieving these EQSs is to reconcile the effluent limits that are technically and economically achievable with ...
