Buckling behavior and compressive failure of composite laminates containing multiple large delaminations
(ELSEVIER SCI LTD, 2009)
In this paper, the effects of the delaminations size on the critical buckling load and compressive failure load of E-glass/epoxy composite laminates with multiple large delaminations are studied. A numerical and experimental ...
An investigation into stainless-steel/structural-alloy-steel bimetal produced by shell mould casting
(ELSEVIER SCI LTD, 2009)
Bimetal consisting of stainless steel (316L) and structural steel (30CrNiMo8) was produced by shell mould casting technique and interface region between two metals was characterized by metallographic examination and ...
Impact toughness and microstructure of continuous steel wire-reinforced cast iron composite
(ELSEVIER SCIENCE SA, 2009)
In this study, improvement of impact toughness of gray cast iron by reinforcing steel fiber was investigated. The composite material was produced by sand mould casting technique. Then, normalizing heat treatment was applied ...
Gingival recession: epidemiology and risk indicators in a university dental hospital in Turkey
(WILEY, 2009)
Objective: Gingival recession is a common manifestation of periodontal disease, but is also associated with several risk factors. In this study, we investigated prevalence of gingival recession and assessed various risk ...
Interpretation of Magnetic Anomalies and Estimation of Depth of Magnetic Crust in Slovakia
(SPRINGER BASEL AG, 2009)
The magnetic map of Slovakia used in the paper was compiled as part of a project titled Atlas of Geophysical maps and profiles in 2001. The residual magnetic data were analyzed to produce Curie point estimates. To remove ...
ELECTRONIC STRUCTURE AND BAND BENDING OF MODULATION-DOPED GaAs/Al-x Ga1-xAs SYMMETRIC AND ASYMMETRIC DOUBLE QUANTUM WELLS UNDER AN APPLIED ELECTRIC FIELD
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
In this study, we have calculated theoretically the effects of the electric field and doping concentration on the sub-band energies, the electron population, and total charge density in modulation-doped symmetric and ...
Diagnostic Value of DNA Hybridization Test for Gardnerella vaginalis, Candida spp., and Trichomonas vaginalis in Women with Vaginal Discharge
(ORTADOGU AD PRES & PUBL CO, 2009)
Objective: The aim of this study was to determine the efficiency of DNA hybridization in women with vaginal discharge evaluated by conventional laboratory methods including wet mount, whiff test, and Gram stain used in ...
Magnetic-field effect on the diamagnetic susceptibility of hydrogenic impurities in quantum well-wires
(ELSEVIER SCIENCE BV, 2009)
We have studied the magnetic field effects on the diamagnetic susceptibility and binding energy of a hydrogenic impurity in a quantum well-wire by taking into account spatially dependent screening. Using the effective-mass ...
Binding energies of donor impurities in modulation-doped GaAs/AlxGa1-xAs double quantum wells under an electric field
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
In this study, we have investigated theoretically the binding energies of shallow donor impurities in modulation-doped GaAs/Al0.33Ga0.67 As double quantum wells (DQWs) under an electric field which is applied along the ...
Effect of the intense laser field on the valance band for Ga1-xAlxAs/GaAs heterostructure
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
The energy levels of holes in symmetric single quantum well under the laser field are theoretically calculated within the framework of the effective mass approximation. Results obtained show that the potential profile and ...
