Unidirectional Tape‐Based Composites from Hemp and Pineapple Leaf Fiber: Mechanical Performance in Conventional and Bio‐Based Matrices

open access: yesAdvanced Engineering Materials, EarlyView.
The study investigates novel semi‐finished products made of unidirectionally arranged hemp or pineapple leaf fiber‐reinforced composites produced from different matrices. The materials are analyzed in terms of their mechanical and interfacial properties and void content.

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

open access: yesAdvanced Engineering Materials, EarlyView.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

The mass function and dynamical mass of young star clusters: Why their initial crossing-time matters crucially

open access: yes, 2012
We highlight the impact of cluster-mass-dependent evolutionary rates upon the evolution of the cluster mass function during violent relaxation, that is, while clusters dynamically respond to the expulsion of their residual star-forming gas.

3D‐Printed Giant Magnetoresistive (GMR) Sensors Based on Self Compliant Springs

open access: yesAdvanced Engineering Materials, EarlyView.
This work explores 3D‐printed GMR sensors utilizing self‐compliant spring structures and conductive PLA composites. By optimizing arm width, we achieved high piezoresistive (0.34%/mm) and magnetoresistive (0.77%/mT) sensitivities. Demonstrated through Bluetooth‐integrated pressure and magnetic position sensing, these full printed low‐cost, customizable

Immigration et criminalisation au Canada : état des lieux

open access: yesCriminologie, 2019
Les intersections entre immigration et criminalisation sont nombreuses. Au Canada, près de 20 ans après l’entrée en vigueur de la Loi sur l’immigration et la protection des réfugiés (LIPR) et à la suite de plusieurs arrêts importants de la Cour suprême ...

Flux penetration and expulsion in thin superconducting disks

open access: yes, 1999
Using an expansion of the order parameter over the eigenfunctions of the linearized first Ginzburg-Landau (GL) equation, we obtain numerically the saddle points of the free energy separating the stable states with different number of vortices.

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

The key to Nigerian prostitution

open access: yesOñati Socio-Legal Series
This paper evidences how prostitution is a process of permanent dehumanization of women. This process is built and reproduced as one place where neoliberalism coincides with the patriarchal exploitation of female bodies.

Medical expulsive therapy

open access: yesIndian Journal of Urology, 2014
The objective of this review article is to present the current literature on medical expulsive therapy (MET) and help guide practitioners in the appropriate use of MET for treatment of stone disease. Kidney stones can be treated with multiple modalities including medical therapy, ureteroscopy, shock wave lithotripsy (SWL), percutaneous ...

The influence of gas expulsion and initial mass-segregation on the stellar mass-function of globular star clusters

open access: yes, 2008
Recently de Marchi, Paresce & Pulone (2007) studied a sample of twenty globular clusters and found that all clusters with high concentrations have steep stellar mass-functions while clusters with low concentration have comparatively shallow mass ...
