Micromechanical Simulation of Fatigue in Nodular Cast Iron
… mechanism. The strain-life, stress-life, notch support effect, and fatigue crack growth are studied using the micromechanical simulations. In all these studies, matrix material is defined as an elastic-plastic with isotropic/kinematic hardening. No damage law is used to define material …

A meta-analysis of the effects of social support on adaptation in Roy's four modes
… was to determine the health outcomes of social support as reported in the published and dissertation nursing research for the years 1984-1989. Meta-analytic methods were utilized in order to determine the effects of social support in the nursing studies. Twenty-one subject-studies comprised the …

The Nucleation and Growth of Nanoparticles for Heterogeneous Catalysis
… nanoparticles and how their interaction with a support affects their reactivity as a heterogeneous catalyst. As capabilities in both synthesis methods and characterization methods advance, the use of nanoparticles and sub-nanometer species are more commonly used. These small particles introduce …

Laminar flame propagation in a stratified charge
… equivalence ratio. Both thermal and chemical effects were crucial for explaining the mechanism of the flame speed enhancement in the transition period. Because of the presence of this 'back-support' effect, the usual concept of specifying the burning velocity as a function of the end gas state …

Assessment of Rib Failure Mechanisms Using Discontinuum Mechanics Based Modeling Approach
… This knowledge is also vital to determine support requirements.</p> <p>The rib control practices used in the 21st Century in most countries originated in roof control techniques. Understandably, applying roof control methods to coal rib does not yield desirable results. The geology of …

Band engineering of metal oxide heterostructures for catalysis applications
Supported metal oxides are used as catalysts for a wide variety of industrially and environmentally important reactions such as the selective oxidation of hydrocarbons and alcohols and the selective catalytic reduction of nitrogen oxides. The support often plays an important role in the activity …
