Binding of some dyes onto crosslinked poly (N-vinylpyrrolidone)
Bindings of some anionic dyes containing sulfonyl group(s), namely, Acid Blue 74 (AB-74), Acid Orange 7 (AO-7), Acid Green I (AG-1), Direct Blue 53 (DB-53), and Calconcarbosylic acid (CCA) onto crosslinked poly(N-vinylpyrrolidone) ...
Swelling studies of copolymeric acrylamide/crotonic acid hydrogels as carriers for agricultural uses
(JOHN WILEY & SONS LTD, 2000)
In this study, highly swollen acrylamide/crotonic acid hydrogels tilt a rod form) containing some inorganic salts such as ammonium nitrate potassium nitrate and ammonium sulphate used as fertilizer, an agricultural drug ...
Increased cell proliferation and R.Msp1 fragmentation induced by 5-aza-2 '-deoxycytidine in rat testes related to the gene imprinting mechanism
(URBAN & FISCHER VERLAG, 2000)
DNA methylation is one of the crucial mechanisms for cellular and tissue differentiation during developmental stages in mammals. 5-aza-2'-deoxycytidine, a specific cytosine DNA Methyltransferase inhibitor, is known to cause ...
Mineralogical and geochemical characteristics of late Cretaceous bentonite deposits of the Kelkit Valley Region, northern Turkey
(MINERALOGICAL SOC, 2000)
Late Cretaceous bentonitic clays in the Kelkit Valley region of Turkey are composed of an alternation of limestone lenses and silicified tuff nodule-bearing pyroclastic rocks and their alteration products. Quartz, feldspar, ...
Generalized statistical convergence and convergence free spaces
(ACADEMIC PRESS INC, 2000)
Many results about statistical convergence in a general setting can be derived by consideration of the convergence free space of null sequences and its related cofilter and filter. We derive algebraic and order properties, ...
Human microphthalmia associated with mutations in the retinal homeobox gene CHX10
(NATURE PUBLISHING GROUP, 2000)
Isolated human microphthalmia/anophthalmia, a cause of congenital blindness, is a clinically and genetically heterogeneous developmental disorder characterized by a small eye and other ocular abnormalities. Three ...

Comparison of body composition analysis methods in clinical routine
Background: Skinfold thickness (SFT) and bioelectrical impedance (BIA) are readily available and commonly used techniques in patient monitoring for body composition analysis (BCA) in clinical practise. Another one, dual-energy ...
Organic facies characteristics of quaternary sediments, Gulf of Izmit, Marmara Sea, Turkey
(V H WINSTON & SON INC, 2000)
The classification of organic facies from samples obtained by submarine drilling between Hersek Burnu and Kaba Burun in the Gulf of Izmit was determined using organic geochemistry methods. The host sediment is composed of ...
An evaluation of the possibilities of using borided GG25 cast iron instead of chilled GG25 cast iron (surface properties)
(ELSEVIER SCIENCE SA, 2000)
In this study, the friction and wear behaviour of chilled and borided GG25 gray cast iron, as used in industry, were investigated. Its surface properties, microstructures, hardness distribution and wear behaviour were ...
