Comparative efficiency testing of a composite hydraulic cylinder

Aviation
The paper points to the increasing use of composite materials in hydraulic components. This entails many benefits, such as weight reduction which is particularly important in aviation. However, new problems arise with the use of new materials.

Community Sanctions as Substitutes to Imprisonment in the Nordic Countries [PDF]

, 2014
Vortex-induced vibrations (VIV) and wake interference on circular cylinders have reached a lot of research attention over the years. However, most research is done for relativly low Reynold numbers (sub-critical) and does not correspond to real world ...

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere

Advanced Engineering Materials, EarlyView.
This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.

Investigation of Thermo‐Chemical Processes in Commercial MgO‐C Refractory Bricks With and Without MgO‐C Recyclate at Elevated Temperatures

Advanced Engineering Materials, EarlyView.
This study investigates thermo‐chemical processes during high‐temperature testing of two commercial MgO‐C brick grades, one containing 47.5 wt.% MgO‐C recyclate. Using ETV, DTA/TG‐MS, XRD, and SEM/EDS/EBSD, mechanisms such as carbothermal reduction of magnesia, impurity incorporation into the secondary MgO surface layer, and calcium‐rich phase ...
