Synthesis and characterization of poly(N-Vinyl-2-pyrrolidone) grafted sodium alginate hydrogel beads for the controlled release of indomethacin
(Wiley, 2008)
Graft copolymers of sodium alginate (NaAlg) with N-vinyl-2-pyrrolidone were prepared using azobisisobutyronitrile as initiator. The graft copolymers (NaAlg-g-PVP) were characterized with Fourier transform infrared spectroscopy, ...
A model for initial-stage sintering thermodynamics of an alumina powder
(Elsevier Science Sa, 2008)
A model was proposed to calculate several thermodynamic parameters for the initial-stage sintering of an alumina powder obtained after calcinations at 900 degrees C for 2 h of a precursor. The precursor was synthesized by ...
Computerized tomography scout view for determining distal femoral resection angle in intramedullary instrumentation of total knee arthroplasty
(Springer, 2007)
This study aims to investigate the results of distal femoral resection by determining the difference between mechanical and anatomical axes of femur using computerized tomography (CT) scout views in pre-operative planning ...
Effect of powder size on infiltration height in producing MgO reinforced Al matrix composite by vacuum infiltration method
(Trans Tech Publications Ltd, 2007)
The vacuum infiltration method is one of the composite producing methods. There are several parameters in composite production by vacuum infiltration. One of them is particle size of reinforcement in particulate reinforced ...
Treatment of radius-ulna and tibia fractures with circular external skeletal fixator in 19 dogs
(Polska Akad Nauk, Polish Acad Sciences, Univ Warmia & Mazury Olsztyn, 2007)
This study was carried out on 19 dogs of different breed, age and sex. 10 different types of radius-ulna and 9 tibia fractures were treated by circular external skeletal fixator. The cases were followed by clinical and ...
P50 variations in Behcet's patients without neurologic findings
(Riyadh Armed Forces Hospital, 2007)
Objective: In the present study, subclinical lesion involvement was investigated using the P50 component in Behcet's patients without neurological manifestation. Methods: We performed this clinical research in Erciyes ...
Artificial neural network application to the friction-stir welding of aluminum plates
(Elsevier Sci Ltd, 2007)
An artificial neural network (ANN) model was developed for the analysis and simulation of the correlation between the friction stir welding (FSW) parameters of aluminium (Al) plates and mechanical properties. The input ...
Molecular dynamics simulation of melting behaviour of small gold clusters: Au-N (N=12-14)
(Iop Publishing Ltd, 2007)
We have investigated the melting behaviour of AuN (N = 12 - 14) clusters by means of molecular dynamics simulation on the basis of the Voter - Chen version of the embedded-atom method. The melting behaviour of the clusters ...
Studies of Al-Ti AHoys by SEM
(Amer Inst Physics, 2007)
Al-Ti (1, 2 wt. %) alloys were investigated by Scanning Electron Microscopy (SEM). SEM observations and energy-dispersive x-ray analyses (EDX) showed that the phase structure of Al-Ti (1 %) alloy at 165 mu m/s is composed ...
Evaluation of Ankara-Istanbul high speed train project
(Vilnius Gediminas Tech Univ, 2007)
Many countries have been carrying out some changes in their transportation policies for the sake of environmental and economical considerations. These circumstances have also affected Turkey to change the national ...
