Drop Test Release Mechanism [PDF]

, 2023
Many boxes for shipping undergo drop tests by the manufacturer to ensure their durability. Certain constraints are necessary to successfully carry out these tests such as not damaging the box prior to the drop and maintaining consistency throughout every

Numerical estimation of errors in drop angle during drop tests of IP-Type metallic transport containers for radioactive materials

Nuclear Engineering and Technology, 2021
For industrial package (IP)-type transport containers for radioactive materials, a free drop test should be conducted under regulatory conditions. Owing to various uncertainties observed during the drop test, errors in drop angles inevitably occur. In IP-

The poisonous truth about the mercury drop test: the effect of elemental mercury on Pd(0) and Pd(II)ArX intermediates [PDF]

, 2023
The mercury drop test is a widely used method for distinguishing between homogeneous and heterogeneous catalysis in organometallic systems. However, recent research has highlighted the limitations of this test due to the intrinsic reactivity of some ...

A sock for foot-drop: A preliminary study on two chronic stroke patients [PDF]

, 2014
Background: Foot-drop is a common motor impairment of chronic stroke patients, which may be addressed with an ankle foot orthosis. Although there is reasonable evidence of effectiveness for ankle foot orthoses, user compliance is sometimes poor.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
