Adsorption of some textile dyes by hexadecyltrimethylammonium bentonite
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 2001)In this study, hexadecyltrimethylammonium (HDTMA) bentonite was synthesized by placing alkylammonium cation onto bentonite. Adsorption of some textile dyes such as Everdirect Supra Yellow PG, Everdirect Supra Orange 26 CG, ... -
A comparison of adsorption isotherms of crosslinked poly(N-vinylpyrrolidone) basic brown 1 binding system
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1996)In this study, the binding of a basic dye such as basic brown 1 [BB 1] onto a crosslinked poly(N-vinylpyrrolidone) [CPVP] was investigated. Adsorption of the azo dye onto the CPVP was studied by the batch adsorption technique ... -
Determination of calcium, magnesium and aluminium in magmatic rocks after ultrasonic leaching by flame AAS
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 2002)A method of ultrasonic leaching has been developed for the destructive analysis of magmatic rock samples'. This method was applied to determine three new elements, Ca, Mg and Al, in magmatic rock samples. The accuracy of ... -
The determination of same heavy metal cations by TLC/photodensitometry
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1996)The samples having complex matrices were analyzed for some heavy metal cations by using a thin layer chromatography/photodensitometry (TLC/PD) system, The rack samples mere dissolved by suitable methods. Nickel, Cobalt and ... -
Determination of trace amounts of iodide by an inhibition kinetic spectrophotometric method
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 2004)In this study, the reaction between Co(III)-EDTA and hypophosphite ion, catalyzed by Pd(II), was chosen as the indicator reaction. The inhibition kinetics of this catalytic reaction were investigated in the presence of ... -
Epidermal growth factor receptor (EGFR) immunolocalization in the male rat reproductive tract during pre- and postnatal periods
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 2000)A number of recent studies suggest the effects of several growth factors as well as genetic factors on the development and differentiation of the testes and excretory ducts. One of the most important growth factors affecting ... -
The first Giardia infection in cattle gall bladder
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 2003)Giardia is a ubiquitously distributed flagellate protozoon that inhabits the small intestine of its host. In this paper, Giardia infection is reported in the gall bladder of an adult cow. Faecal samples from asymptomatic ... -
Influence of some crosslinkers on the swelling of acrylamide crotonic acid hydrogels
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1997)Acrylamide-crotonic acid hydrogels in the form of rods are prepared by gamma-irradiation of quaternary mixtures of acrylamide-crotonic acid-crosslinker-water with 2.6 and 5.2 kGy gamma-rays. The influence of the applied ... -
Investigation of acid sites on V2O5/Nb2O5 catalysts by FTIR
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1995)In this study the V2O5/Nb2O5 catalysts were prepared using grafting and impregnation techniques. Both the V2O5/Nb2O5 prepared catalysts and the adsorption of pyridine on V2O5/Nb2O5 have been studied with FTIR spectroscopy. ... -
Investigation of acid sites on V2O5/TiO2(A) catalysts by FTIR with adsorption of pyridine
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1996)The V2O5/TiO2(A) catalysts were prepared by the grafting and their Bronsted and Lewis acid sites were investigated with pyridine adsorption by using FTIR Spectroscopy. The results obtained showed that monolayer or less ... -
Karyotype analysis in Alburnus heckeli (Battalgil, 1943) from Lake Hazer
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 2004)Karyotype analysis was performed on Alburnus heckeli (Battalgil, 1943) (Earn: Cyprinidae) by investigating the number and structures of its chromosomes. The fish used in this study were caught with fishing nets in Lake ... -
Removal of water-soluble cationic dyes with TriSyl silicas
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1998)In this study, the adsorption of certain water-soluble cationic dyes, (basic blue 9, basic blue 12, basic blue 17, brilliant cresyl blue, janus green B, basic green 4, basic violet 1, basic violet 3, and thionin) onto ... -
Renal morphogenesis of rat fetus
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1997)The Kidneys, during pro-, meso-, and metanephros stages of the development of the nephrotome, display different structural features. In this work, the renal tissue samples obtained from prenatal 10-, 13-, 14-, 15-, 16-, ... -
