Characterization of Nitinol Produced by Laser Powder Bed Fusion for Mechanical Metamaterial Applications

open access: yesAdvanced Engineering Materials, EarlyView.
Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Artifacts in the Raymond Powell Collection from East Texas [PDF]

open access: yes, 2012
In March 2010, Raymond Powell of Mansfield, Louisiana, allowed the examination and photographic documentation of several artifacts in his possession. The specimens were given to him approximately 60 years ago by a friend who reportedly excavated them ...

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 ...

Fertility as blessing and infertility as curse in the ancient Near East and the Old Testament [PDF]

open access: yes, 1986
Fertility and infertility are amongst the most important subjects in curses and blessings in the Ancient Near East and in the· Old Testament. Fertility was especially linked to three spheres: bumper crops, thriving livestock and a growing family. This

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Exchange Rate Arrangements for East Asia Post-Crisis: Examining the Case for Open Economy Inflation Targeting [PDF]

open access: yes
The infeasibility of a monetary union for East Asia in the near future, as well as the limitations of other forms of super fixes, appears to leave a flexible regime as the only viable policy option.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Development of a qRT - PCR Diagnostic Kit for the Detection of FCoV

open access: yesCyprus Journal of Medical Sciences
BACKGROUND/AIMS: In recent years, feline infectious peritonitis (FIP), which led to the death of more than 3,000 cats on the island of Cyprus, has become a significant concern. FIP is a fatal disease in cats caused by feline coronavirus (FCoV).
