Internal auditing in the turkish banking sector
(1989)The origins of modern commercial banking in Turkey are closely interwoven with the problems of public finance in the 1840s. The first paper note issue of 1840 produced instability in the foreign exchange markets. So, in ... -
Epoxidation of Styrene with Aqueous Hypochlorite Catalyzed by a Manganese (III) Porphyrin Bound to Colloidal Anion-Exchange Particles
(1991)Epoxidation of styrene in aqueous sodium hypochlorite solution was catalyzed by the tetrasodium salt of 5,10,15,20-tetrakis(2,6-dichloro-3-sulfonatophenyl)porphinatomanganese(III) chloride (1). Manganese porphyrin 1 was ... -
Designing instructional materials with desktop publishing software: The effect of white-space variations on learning
(1992)As more and more people gain access to personal computers and powerful desktop-publishing software, many teachers and trainers are producing their own instructional materials using desktop publishing. The new desktop-publishing ... -
Alkaloids and a lignan from Aristolochia ponticum
(1991)A methanolic extract of the roots of Aristolochia ponticum has yielded two aristolochic acid derivatives, three aristolactams and a 2,3,4,5-substituted furan lignan. The known compounds aristolochic acid I, aristolochic ... -
Modeling and applications of space manipulators
(Publ by ASME, New York, NY, United States, 1992)To control robot or teleoperated manipulators in space, the motion of the satellite (which is actually the base of the manipulator) which will move due to the force exerted by the moving manipulator, must be considered. ... -
Decentralized optimal control for uncertain systems
(Publ by American Automatic Control Council, Green Valley, AZ, United States, 1992)Performance robustness problem for decentralized control systems is discussed within a state-space framework. The performance is measured with a quadratic index. Both structured and unstructured perturbations of the system ... -
Froth washing technology in mechanical flotation machines
(1992)This paper concentrates on the five recent plant trials/applications of froth washing in mechanical flotation cells in North America. Increased froth cleaning yielded better upgrading and some cases slightly improved ... -
Studies on the extraction of Pinus brutia bark using the Gulbaran extractor-diffuser
(1990)In this study, extraction of Pinus brutia bark is performed using a new extractor-diffuser system. This new extraction system uses a moving bed of bark which is continuously washed with fresh solvent sprayed from mobile ... -
Studies on the synthesis of some 2-(1',3'-benzodioxol-5'yl)-benzimidazole, benzothiazole and benzoxazole derivatives

A-type proanthocyanidins from Prunus spinosa
(1991)The range of natural dimeric A-type proanthocyanidins is extended by identification of ent-epicatechin-(4? › 8; 2? › O › 7)-catechin and ent-epiafzelechin-(4? › 8;2? › O › 7)-epicatechin. They are accompanied in the flowers ... -
Aristolochic acids and aristolactams from Aristolochia auricularia
(1991)A methanolic extract of the roots of Aristolochia auricularia was found to contain seven known compounds, aristolochic acids I, II, III and IV and aristolactams I, II and III. In addition, four novel compounds, the methyl ... -
Prediction of ripping machine performance in terms of rockmass properties
(1991)The rockmass parameters that affect the productivity of tractor mounted ripping are briefly reviewed. The results of a number of field ripping trials in a variety of sedimentary rocks on the Western Lignite opencast mines ... -
Essential oil composition of four Origanum vulgare subspecies of Anatolian origin
(1993)Essential oil composition of four subspecies of Origanum vulgare L. (Labiatae, Sect. Majorana); subsp. hirtum (Link) Ietswaart, subsp. gracile (C. Koch) Ietswaart, subsp. vulgare and subsp. viride (Boiss.) Hayek growing ... -
Decentralized routing controller for congested highways
(IEEE, Piscataway, NJ, United States, 1995)A decentralized controller for dynamic routing in multi-destination transportation networks is presented. The proposed algorithm is especially suited for congested networks, where the traffic demand is close to or more ... -
Robust controller design for flexible robot manipulators: an optimal output feedback controller design approach
(IEEE, Piscataway, NJ, United States, 1994)A robust optimal output feedback controller design approach is proposed and applied to the controller design problem for one-link flexible robot manipulators. The flexible dynamics of a robot manipulator is represented by ... -
Minimax optimal control for uncertain systems
(American Automatic Control Council, Green Valley, AZ, United States, 1994)The issue of performance robustness is considered in a dynamic game framework where the goal is to find a feedback controller which stabilizes the system under all plant perturbations and which minimizes the value of a ... -
Composition of the essential oils of Turkish Origanum species with commercial importance
(1993)In Turkey Origanum is represented by 23 species comprising 31 taxa. Commercially important Origanum species include O. onites, O. majorana, O. minutiflorum, O. vulgare and O. syriacum. These species are annually exported ...
