Evaluation of venous ulcers
(1999)
Alt ekstremitenin venöz staz ülserleri yaygın olarak görülür ve nüfusun %1'ini potansiyel olarak etkiler. Kronik venöz yetmezliği olan hastaların yaklaşık olarak üçte birinde on yılı aşkın bir sürede alt ekstremite ülserleri ...
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 effect of lead inhalation on rat lung morphology
(1999)
Lead may exert toxic effects on several organ systems, but those in the lung are the most insidious. Therefore the aim of the present study was to investigate the morphological alterations caused by lead intoxication in ...
Binding energies of excitons in symmetric and asymmetric coupled double-quantum well structures in a magnetic field
(1999)
The binding energy of excitons in the symmetric and asymmetric coupled double GaAs/$Ga_{1-x}Al_xAs$ quantum wells is calculated by using variational approach. Results have been obtained as a function of the potential ...
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 ...
The orbit center dependence of the energy levels in a multiple quantum wells under external tilted magnetic and electric fields
(1999)
An analytical solution to the Schrödinger equation for a multiple quantum well system subjected to an externally applied electric field the growth direction and an externally applied tilted magnetic field are obtained ...
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 ...
Heat transfer and flow structures around circular cylinders in cross-flow
(1999)
Şaşırtılmış boru demeti ve tek sıralı borular içerisine yerleştirilmiş olan bir borudan ısı transferi ve akış yapılarının araştırılması için deneysel bir çalışma yapılmıştır. Sırasıyla $S_t$ ve $S_l$ düşey eksenel boşluk ...
