Pathways to Children’s Behavioral Problems during the COVID-19 Pandemic: Fathers’ Parenting Stress and Parenting Approaches

open access: yesChildren, 2023
Although the family stress model theoretically focuses on the roles of both mothers and fathers as predictors of children’s outcomes, studies generally have focused on mothers.

Molecular responses of mouse macrophages to copper and copper oxide nanoparticles inferred from proteomic analyses [PDF]

open access: yes, 2013
The molecular responses of macrophages to copper-based nanoparticles have been investigated via a combination of proteomic and biochemical approaches, using the RAW264.7 cell line as a model.

On fatigue life predictions for notched members by the nominal stress-based and the local strain-based methods

open access: yesApplied and Computational Mechanics, 2022
Traditional engineering models for addressing fatigue issues are based on empirical relations between the necessary number of cycles for fatigue failures N_f and either, the nominal stress σ_an or the local strain ε_a amplitudes.

Quantifying the Contribution of Crystallographic Texture and Grain Morphology on the Elastic and Plastic Anisotropy of bcc Steel [PDF]

open access: yes, 2019
The influence of grain shape and crystallographic orientation on the global and local elastic and plastic behaviour of strongly textured materials is investigated with the help of full-field simulations based on texture data from electron backscatter ...

The Use of Dietary Additives in Fish Stress Mitigation: Comparative Endocrine and Physiological Responses [PDF]

open access: yes, 2019
In the last years, studies on stress attenuation in fish have progressively grown. This is mainly due to the interest of institutions, producers, aquarists and consumers in improving the welfare of farmed fish.

On the use of the Peak Stress Method for the calculation of Residual Notch Stress Intensity Factors: a preliminary investigation [PDF]

open access: yes, 2017
Residual stresses induced by welding processes significantly affect the engineering properties of structural components. If the toe region of a butt-welded joint is modeled as a sharp V-notch, the distribution of the residual stresses in that zone is ...

Triple-deck and direct numerical simulation analyses high-speed subsonic flows past a roughness element [PDF]

open access: yes, 2015
This paper is concerned with the boundary-layer separation in subsonic and transonic flows caused by a two-dimensional isolated wall roughness. The process of the separation is analysed by means of two approaches: the direct numerical simulation (DNS) of

Annular shear of cohesionless granular materials: from inertial to quasistatic regime [PDF]

open access: yes, 2008
Using discrete simulations, we investigate the behavior of a model granular material within an annular shear cell. Specifically, two-dimensional assemblies of disks are placed between two circular walls, the inner one rotating with prescribed angular ...

Time-frequency analysis of financial stress and global commodities prices: Insights from wavelet-based approaches

open access: yesCogent Economics & Finance, 2022
We examine the time-frequency lead–lag relationships and the degree of integration between the US financial stress index and global commodity prices (i.e., oil, gold, silver, and cocoa) with data covering over 47 decades (January 1975 to December 2021 ...

Generic and rhetorical structures of texts : two sides of the same coin? [PDF]

open access: yes, 2005
Two major approaches to textual macro-structures have been developed during the last decades: Register & Genre Theory (R>) and Rhetorical Structure Theory (RST).
