Some results on the spectral decomposition of the axial m-index assignment problem
(1999)
In this paper, axial m-index assignment problem is reformulated as a linear programming problem and several algebraic characterizations of the coefficient matrix A of its problem are derived from known characterizations ...
A comparison of adsorption isotherms of crosslinked poly (N-vinylpyrrolidone)/ basic brown 1 binding system
(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 ...
Factors affecting the natural hydrophobicity of coal
(1996)
Flotasyon, agglomerasyon ve flokülasyon gibi birçok proses tekniklerinde kömürün hidrofobik (suyu itme) ve hidrofilik (suyu çekme) özelliklerinin çok önemli bir rol oynadığı bilinmektedir. Proses esnasında partiküllerin ...
Influence of some crosslinkers on the swelling of acrylamide-crotonic acid hydrogels
(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 ...
Some properties of almost continuous multifunctions defined between bitopological spaces
(1996)
Bu çalışmada iki topolojili uzaylar arasında tanımlı çoğul değerli fonksiyonlar için Mukherjee-Ganguly tarafından tanımlanan alttan-üstten almost süreklilik ile Bose-Sinha tarafından tanımlanan zayıf süreklilik kavramlarının ...
On statistically rotation sets for maps of the $C_m$ - class
(1997)
Bu makalede, rotasyon kümeleri ve istatistiksel yakınsaklık altında $C_m$- sınıfının dönüşümlerine göre istatistiksel rotasyon kümeleri ortaya konulmuştur.
Sorption of methylene blue from water by organoclays
(1999)
Isotherms were measured for sorption of methylene blue by organoclays. The organoclays were prepared from kaolinite and bentonite by replacing the natural exchangable cations of the quaternary ammonium ions HDTMA ...
Ab initio study of the protometric tautomerism of adenine
(1999)
Eight tautomers of adenine have been studied by using ab initio theory in the gas phase and in solution. Their stability order has been determined by using the HF/3-21G approximation. The HF/3-21G level calculations predict ...
Some textile dyes adsorption by crosslinked poly (N-vinylpyrrolidone)
(1998)
Bu çalışmada tekstil endüstrisinde kullanılmakta olan Everdirect Supra yellow PG, Everdirect Supra orange 26 CG, Everdirect Supra Rubine BL, Everdirect Supra Blue 4LB, and Everdirect Supra Red BWS gibi bazı boyaların çapraz ...
