Temperature dependence of ZnO rods produced by ultrasonic spray pyrolysis method
(Elsevier Science Sa, 2007)
Zinc oxide (ZnO) microrods were prepared at different substrate temperatures by ultrasonic spray pyrolysis technique on glass substrates. The X-ray diffraction patterns show that obtained rods are composed of wurtzite-type ...
A customer threshold property for closed finite queueing networks
(Elsevier Science Bv, 2006)
We present a new class of finite queues in cyclic networks with production blocking. We show that with a threshold property related to the number of customers in the network, these queues are insensitive to the allocation ...
Contemporary techniques and safety of cardiovascular procedures in the surgical management of renal cell carcinoma with tumor thrombus
(Mosby-Elsevier, 2006)
Objective: Renal cell carcinomas often form venous thrombi that extend into the vena cava. Frequently, cardiovascular consultation is necessary for complete surgical excision. We sought to investigate the risk factors, ...
Effect of zirconium-oxide ceramic surface treatments on the bond strength to adhesive resin
(Mosby-Elsevier, 2006)
Statement of problem. Surface treatment methods used for resin bonding to conventional silica-based dental ceramics are not reliable for zirconium-oxide ceramics. Purpose. The aim of this study was to compare the effects ...
Protective effects of trapidil in ischemia-reperfusion injury due to testicular torsion and detorsion: An experimental study
(Blackwell Publishing, 2006)
Objective: We aimed to detect the preventive effects of trapidil in ischemia reperfusion (IR) injury due to testicular torsion and detorsion. Methods: Forty prepubertal albino rats were used. In the IR group, torsion was ...
Some aspects of thermally induced martensite in Fe-30% Ni-5% Cu alloy
(Elsevier Science Bv, 2007)
Kinetical, morphological, crystallographical and several thermal properties of thermally induced martensite in the austenite phase of Fe-30% Ni-5% Cu alloy were investigated. Scanning electron microscope (SEM), transmission ...
The estimates of approximation by using a new type of weighted modulus of continuity
(Pergamon-Elsevier Science Ltd, 2007)
In this paper, we introduce a new type modulus of continuity for function f belonging to a particular weighted subspace of C (0, infinity) and show that it has some properties of ordinary modulus of continuity. We obtain ...
Catalytic enantioselective addition of diethylzinc to aldehydes using aziridine based chiral ligands
(Pergamon-Elsevier Science Ltd, 2007)
The readily available ferrocenyl substituted aziridinylmethanol 1 (FAM-1) was used as a chiral catalyst in the diethylzinc addition reaction to aromatic and aliphatic aldehydes to give secondary alcohols in high yields and ...
Delayed orbital subperiosteal hemorrhage after blunt trauma
(Lippincott Williams & Wilkins, 2007)
A 21-year-old man presented with sudden-onset orbital hemorrhage, vision loss, and epistaxis 4 days after experiencing blunt trauma. Computed tomography revealed a subperiosteal hematoma in the medial orbit, extending to ...
