Design optimization of cutting parameters when turning hardened AISI 4140 steel (63 HRC) with Al2O3+TiCN mixed ceramic tool
(Elsevier Sci Ltd, 2007)
Due to their high hardness and wear resistance, Al2O3-based ceramics are one of the most suitable cutting tool materials for machining hardened steels. However, their high degree of brittleness usually leads to inconsistent ...
Designing of a powder compressing device with vibration and investigation of compressibility of MgO powders with this device
(Elsevier Sci Ltd, 2007)
One of metal matrix composite (MMC) production methods is infiltration of liquid metal into preformed reinforcement. In this method, MMCs are produced by infiltration of liquid metal into preformed reinforcement using one ...
Determination of residual stresses based on heat treatment conditions and densities on a hybrid (FLN2-4405) powder metallurgy steel using artificial neural network
(Elsevier Sci Ltd, 2007)
This paper presents a new approach based on artificial neural networks (ANNs) to determine the residual stresses in PM steel based nickel (FLN2-4405). This study consists of two cases: (i) The experimental analysis: The ...
Modelling of yield length in the mould of commercial plastics using artificial neural networks
(Elsevier Sci Ltd, 2007)
According to the yield length of a plastic, whether a mould is filled fully or not can be estimated. In this study, a new formula based on various injection parameters was developed to determine the yield length in plastic ...
The role of sensory nerve conduction study of the palmar cutaneous nerve in the diagnosis of carpal tunnel syndrome in patients with polyneuropathy
(Neurol Soc India, 2007)
Background: Conventional methods in the diagnosis of carpal tunnel syndrome (CTS) in patients with polyneuropathy (PNP) are insufficient. Aims: We suggest that the comparison of the conduction of the median nerve with that ...
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 ...
Cephalaria duzceensis (Dipsacaceae), a new species from the western Black Sea region, Turkey
(Wiley, 2007)
A new species, Cephalaria duzceensis N. Aksoy & R. S. Gokturk (Dipsacaceae) from western Black Sea region of Turkey is described. It is illustrated in line drawings and the morphology of the new species is compared with ...
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 ...
Risk of respiratory distress in the patients who were applied nasal packing at the end of nasal surgery
(Elsevier Sci Ltd, 2008)
Objective: This prospective study investigated the risk of respiratory distress in the patients who were applied nasal packing at the end of nasal surgery; and effects of nasal packing on consciousness level while the ...
Venous vascular malformations of the craniofacial region: pre-operative embolisation with direct percutaneous puncture and N-butyl cyanoacrylate
(British Inst Radiology, 2008)
Craniofacial venous vascular malformations cause severe cosmetic problems and yet these lesions are not candidates for transcatheter embolisation owing to the lack of arterial feeders. The purpose of this study was to ...
