Chemoenzymatic synthesis of 2-brorno-6-hydroxy-3-methoxy-2-cyclohexen-1-one
(Scientific Technical Research Council Turkey-Tubitak, 2007)
A chemoenzymatic synthesis of 2-bromo-6-hydroxy-3-methoxy-2-cyclohexen-1-one starting from cyclohexane-1,3-dione is reported. Manganese (III) acetate-mediated acetoxylation followed by the enzyme-mediated hydrolysis of ...
Application of Smeed and Andreassen accident models for Turkey: Various scenario analyses
(Gazi Univ, Fac Engineering Architecture, 2008)
In this study, accident prediction models for Turkey were developed by using the historical data, between 1986 and 2005, including population (P), the number of vehicles (N), accidents (C), injuries (I), and fatalities ...
Is Cervicotomy Enough for Removal of Retrosternal Goiters?
(Tubitak Scientific & Technical Research Council Turkey, 2008)
Aim: The aim of this study was to evaluate the surgical approaches in retrosternal goiters. Materials and Methods: We reviewed 23 patients operated with the diagnosis of retrosternal goiter. Twelve (52%) of the cases were ...
Minimizing the maximum lateness in a scheduling problem with a time-dependent learning effect: A non-linear programming model
(Gazi Univ, Fac Engineering Architecture, 2008)
In traditional scheduling problems, most literature assumes that the processing time of a job is fixed. However, there are many situations where the processing time of a job depends on the starting time or the position of ...
Second Order Elastic Constants and some thermoelastic properties of alkali halides using Woodcock potential
(2001)
Second Order Elastic Constants (S.O.E.C) of NaCl-type crystals have been calculated using the Woodcock potential. Short-range repulsive interactions have been included up to second-nearest neighbors. This potential form ...
Modeling of the vibrations caused by ball bearing defects
(2003)
In this study a shaft-ball bearing system is modeled in order to investigate the vibrations of ball bearings with running surfaces defects. Shaft and bearing was modeled as mass-spring system and balls were assumed have ...
Primary repair of a sternal cleft in an infant with autogenous tissues
(2003)
A cleft sternum is a rare congenital anomaly often diagnosed as asymptomatic at birth. Clinical outcome may be unfavorable when an associated anomaly, particularly an intracardiac anomaly coexists with the defect. Primary ...
Respiratory findings in gun factory workers exposed to solvents
(W.B. Saunders Ltd, 2004)
Objective: Gun factory workers are exposed to many solvents (toluene, acetone, butanol, xylene, benzene, trichloroethylene). We investigated whether chronic exposure to solvents had adverse effect on respiratory system. ...

(2005)
Purpose: The purpose of the study was to describe-computed tomography (CT) and ultrasonography findings in superior mesenteric artery syndrome (SMAS). Materials and methods: The study was performed on 89 CT examinations. ...
Column of bertin: Normal sonographic findings
(2005)
Introduction: We aimed to describe the normal and pathologic sonographic (US) findings of column of Bertin (CB). Materials and methods: The study was performed on sixty-six patients who had CB on CT. CB was found to be ...
