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 ...
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 ...
The determination of some heavy metal cations by TLC/ photodensitometry
(1996)
The samples having complex matrices were analyzed for some heavy metal cations by using a thin layer chromatography/photodensitometry (TLC/PD) system. The rock samples were dissolved by suitable methods. Nickel, Cobalt and ...
Catalytic-oxidative destruction of benzo-b-thiophene by Fenton' s reagent
(1999)
In order to determine the oxidation behaviour of benzo-b-thiophene, destructive oxidation using Fenton's reagent was studied. Benzo-b-thiophene was converted to benzo-b-thiophene-S,S-dioxide but oxidation resulted mainly ...
