A novel rapid cooling assembly design in a high-pressure cubic press apparatus

open access: yesMatter and Radiation at Extremes
In traditional high-pressure–temperature assembly design, priority has been given to temperature insulation and retention at high pressures. This limits the efficiency of cooling of samples at the end of experiments, with a negative impact on many ...

ENGINEERING CONCEPTS IN ANALYSING LUMBOSACRAL LOAD IN POST-OPERATIVE SCOLIOTIC PATIENTS [PDF]

open access: yesJournal of Engineering Science and Technology, 2018
Lumbosacral alignment plays a major role in the mechanical low back pain in normal population. Malalignment causes increased strain to the muscles and ligaments around it which eventually leads to mechanical low back pain and discomfort.

Effect of nose bluntness and afterbody shape on aerodynamic characteristics of a monoplanar missile concept with bodies of circular and elliptical cross sections at a Mach number of 2.50 [PDF]

open access: yes
The tests were performed at a Mach number of 2.50 and at angles of attack from about -4 deg to 32 deg. The results indicate that increasing nose bluntness increases zero lift drag and decreases both the maximum lift-drag ratio and the level of ...

Asymmetric charge distribution boosts hydrogen evolution performance in two‐dimensional MoO2/MoS2 step heterostructure

open access: yesCarbon Energy
Step heterostructures are predicted to hold a profound catalytic performance because of the rearranged electronic structure at their interface. However, limitations in the morphology of heterostructures prepared by hydrothermal reactions or molten salt ...

Evaluation of pressure and thermal data from a wind tunnel test of a large-scale, powered, STOL fighter model [PDF]

open access: yes
A STOL fighter model employing the vectored-engine-over wing concept was tested at low speeds in the NASA/Ames 40 by 80-foot wind tunnel. The model, approximately 0.75 scale of an operational fighter, was powered by two General Electric J-97 turbojet ...
