Experimental investigation of fatigue crack initiation from notch for 2024 T351 Al-alloy

open access: yesFracture and Structural Integrity, 2020
In this investigation, fatigue criterion was established to predict crack-initiation at the tip of a notch in aged hardening aluminum alloy. This criterion was used to predict the residual lifetime in aeronautical structures using concept of local stress

Residual stress field of HIPed silicon nitride rolling elements [PDF]

open access: yes, 2002
The residual stress field of HIPed Si3N4 rolling elements were studied. Two kinds of HIPed Si3N4 ball blanks self-finished at different nominal lapping loads ranging from 1.3 to 10.87 kgf/ball and four kinds of commercially finished 1/2 in (12.7 mm ...

Kaluza-Klein Reduction of a Quadratic Curvature Model [PDF]

open access: yes, 2010
Palatini variational principle is implemented on a five dimensional quadratic curvature gravity model, rendering two sets of equations which can be interpreted as the field equations and the stress-energy tensor.

Genotypic variation in morpho-physiological and stomatal response to salinity in white mustard (Sinapis alba L.)

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca
Salinity negatively affects plant growth by inhibiting germination, emergence, yield, and quality; therefore, it is important to select salt-tolerant plants.

Magnetostrictive behaviour of thin superconducting disks

open access: yes, 2003
Flux-pinning-induced stress and strain distributions in a thin disk superconductor in a perpendicular magnetic field is analyzed. We calculate the body forces, solve the magneto-elastic problem and derive formulas for all stress and strain components ...

Cyclic electric field stress on bipolar resistive switching devices [PDF]

open access: yes, 2013
We have studied the effects of accumulating cyclic electrical pulses of increasing amplitude on the non-volatile resistance state of interfaces made by sputtering a metal (Au, Pt) on top of the surface of a cuprate superconductor YBa$_2$Cu$_3$O$_{7 ...

Modeling of torsion stress giant magnetoimpedance in amorphous wires with negative magnetostriction

open access: yes, 2007
A model describing the influence of torsion stress on the giant magnetoimpedance in amorphous wires with negative magnetostriction is proposed. The wire impedance is found by means of the solution of Maxwell equations together with the Landau-Lifshitz ...

Genome-Wide Association Studies of Agronomic and Quality Traits in Durum Wheat

open access: yesAgriculture
Durum wheat is mainly used for products for human consumption, the quality of which depends on the content of protein and yellow pigments in the semolina.

Electromagnetic Fields, Oxidative Stress, and Neurodegeneration [PDF]

open access: yesInternational Journal of Cell Biology, 2012
Electromagnetic fields (EMFs) originating both from both natural and manmade sources permeate our environment. As people are continuously exposed to EMFs in everyday life, it is a matter of great debate whether they can be harmful to human health.
