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 ...
Estimation of global monthly irradiation from sunshine duration data at Sivas, Turkey
(2002)
Sivas'ta 1992-1994 yıllarında yatay düzleme gelen toplam günlük güneş ışınımının aylık ortalama değerleri üç ayrı metotla hesaplanarak aynı zaman aralığında ölçülen mütekabil değerleri ile karşılaştırılmışım Hesaplamada ...
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 ...
Jordan left derivations on completely prime gamma rings
(2002)
Bu çalışmada $\Gamma$ halkaları üzerinde Jordan sol türev tanımı verilmiş ve tamamen (completely) asal bir $\Gamma$ halkası üzerinde bir Jordan sol türev varsa,$\Gamma$ halkasının belirli bir koşulu sağlaması halinde değişme ...
On statistical rotation shadowing property for homeomorphism maps
(2000)
Bu çalışmada istatistiksel yakınsaklık kavramı ve bir x dizisinin istatistiksel limit noktaları, x'in istatistiksel rotasyon aralığının tanımını veriyoruz. Daha sonra, homeomorfizm dönüşümleri için rotasyon kümelerinin ...
A solar domestic hot water system simulation study in Sivas, Turkey
(2004)
Sivas'ta konut içi kullanım amaçlı sıcak su temini için tasarlanan güneş enerjisi destekli bir sistemin simülasyonu yapılmıştır. Bu amaçla, MATLAB dilinde bir bilgisayar programı geliştirilmiştir. Sistem verimi ve optimum ...
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 ...
Theoretical investigation of the E/Z isomerization and molecular geometries of enamines
(1999)
The E/Z İsomerization of some simple enamines (H2NCH=CHR, R=NO2, CHO, CN, COCH3, COOH) has been investigated by means of quantum-chemical calculations at the HF level using 6-31G* and 6-31+G** basis sets. The single- point ...
Kinetics of reduction of Maxilon blue-SG by sulfide ion: Kinetic salt effect in elucidation of reaction mechanism
(2002)
The reaction between Maxilon blue $(MB^+)$ and the sulfide ion is an ideal kinetic experiment in order to show the dependence of the reaction rate on the concentrations of reactants, ionic strength and temperature. By using ...
