Electrochemical effects in flotation of a Turkish complex sulphide ore
(1995)There are many reported studies of selective flotation based on control of redox potential (Eh). Most of the studies show that flotation of chalcopyrite, pyrite, sphalerite and galena with xanthate collector show a strong ... -
Relation with the age of the histological variations in the compact layer of the long bones [Uzun kemiklerin kompakt tabakasindaki histolojik degişimlerin yaş ile olan i·lişkisi]
(1996)This research has been made on the long bones of the extremities of the rabbits, Lepus capensis. It has been established in which indicated correlation in very high values the age of this numerically change by optaining ... -
Histogram based fuzzy Kohonen clustering network for image segmentation
(IEEE, Los Alamitos, CA, United States, 1996)In this study, a Fuzzy Kohonen Clustering Networks (FKCN) algorithm is proposed for image segmentation. The large image sizes are in general required for various types of imaging applications. For large amounts of data, ... -

(1996)[No abstract available] -
Purification and characterization of dog-rose (Rosa dumalis Rechst) polyphenol oxidase
(AMER CHEMICAL SOC, 1996)Polyphenol oxidase (PPO) of dog-rose fruit was extracted and purified through (NH4)(2)SO4 precipitation, dialysis, gel filtration, and DEAE-Sephacel ion-exchange chromatography. The sample obtained from ammonium sulfate ... -
Gain and noise figure characterisation of a 68 km long distributed erbium doped fibre amplifier
(Institution of Engineering and Technology, 1996)The authors report the detailed gain and noise figure characterisation of a 68km long distributed erbium doped fibre amplifier (DEDFA) using a fibre design optimised for this application. The results, representing significant ... -
A cosmological approach to a high-order effective field theory
(1996)A class of cosmological solutions is found to the vacuum field equations of an effective field theory derived from string theory in a (10 - ?)-dimensional spacetime. This effective field theory concerns only the massless ... -
New Floristic Records for the Fern Flora of Turkey
(1996)New records are given for 23 fern species in Turkey. -
Seasonal Variations in the Chemical Compositions of Essential Oils of Selected Aromatic Plants Growing Wild in Turkey
(American Chemical Society, 1997)The summer leaves of Thymbra spicata var. spicata and Satureja thymbra, two Labiatae aromatic shrubs growing wild in the East Mediterranean region of Turkey, and, in addition, the leaves of Salvia fruticosa, Mentha pulegium, ... -
Influences of thermal annealing, the electrolyte pH, and current density on the interface state density distribution of anodic MOS structures
(Springer Verlag, 1997)An investigation of the effect of thermal annealing and anodization parameters, such as the electrolyte pH and current density, on capacitance-voltage and interface state density distribution characteristics has been made. ... -
Effect of high-temperature and salt (NaCl) stresses on polyphenoloxidase activity during seed germination
(1997)The ability of the polyphenoloxidase (PPO) enzyme in the embryos and food tissues of the seeds of bean (Phaseolus vulgaris L. cv. Magnum) and corn (Zea mays L. cv. Merit) to oxidize the substrates of dopa and catechol was ... -
Spectral characteristics of long span distributed erbium doped fibre amplifiers (DEDFAs) for soliton transmission
(Institution of Engineering and Technology, 1997)The authors present a detailed spectral characterisation of an optimally designed 60km long DEDFA for soliton transmission. From this, the optimum wavelength for single channel and WDM soliton transmission in such systems ... -
