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, ...
Photocatalytic oxidative degradation of 2-methylthiophene in suspensions of TiO2: identification of intermediates and degradation pathways
(ELSEVIER SCIENCE SA, 2001)
The photocatalytic oxidative degradation of 2-methylthiophene has been investigated in aqueous suspensions of TiO2. The nature of the degradation products was investigated using GC/MS. The effects of the nature of the ...
Solvent effects on dimeric self-association of 2-pyrrolidinone: An ab initio study
(KLUWER ACADEMIC PUBL, 2001)
Full geometry optimizations were carried out for 2-pyrrolidinone (2-Py) and its dimer structures at the DFT (B3LYP) and HF levels in the gas phase and in solution. Additionally, single-point MP2/6-31G** calculations were ...
Differential effect of cold acclimation on blood composition in rats and hamsters
(SPRINGER HEIDELBERG, 2001)
Male rats and hamsters were exposed to a progressively lower air temperature and shorter photoperiod to simulate the onset of winter. Normothermic hamsters had a higher haematological oxygen carrying capacity (OCC) and ...

"Petrol sistemi" kavramı, petrol ve gazın oluşumuyla başlayan, göçen ve sonuçta kapanlanan bir dizi jeolojik olaylara dayanır. Bu terim, hidrokarbon birikimi sağlayabilecek oluşumlara yeni bir bakışı kapsar. Bir petrol ...
Total lipid content and fatty acid composition of the seeds of some Vicia L. species
(ELSEVIER SCI LTD, 2001)
The seed oils of eight Vicia species (Leguminosae) were investigated for their total lipid contents and fatty acid compositions. The seed lipid contents were found to be between 2.30 and 3.91%. The fatty acid compositions ...
Poly(hydroxamic acid) hydrogels from poly(acrylamide): preparation and characterization
(SPRINGER-VERLAG, 2001)
Poly(hydroxamic acid) (PHA) hydrogels from crosslinked poly(acrylamide) (PAAm) hydrogels, containing different type crosslinkers such as such as N, N'-methylene bisacrylamide (N) and ethyleneglycol dimethacrylate (E). The ...
Inhibitor effect of omeprazole in isolated human myometrial smooth muscle
(PERGAMON-ELSEVIER SCIENCE LTD, 2001)
The aim of the present study was to investigate the effect of omeprazole, an H+-K+-ATPase inhibitor, in myometrial smooth muscle strips from women undergoing elective caesarean section at term. Isolated myometrial strips ...
Radiation induced superabsorbent hydrogels. Acrylamide/itaconic acid copolymers
(WILEY-V C H VERLAG GMBH, 2001)
Acrylamide/itaconic acid hydrogels in the form of rods are prepared by gamma -irradiation of ternary mixtures of acrylamide/itaconic acid/water with 2.00-5.71 kGy gamma -rays. Spectroscopic and thermal characteristic the ...
Koyulhisar heyelanlarına yapısal ve jeomorfolojik açıdan bakış
