Size Effects on Mechanical Properties of Copper Thin Sheet in Uniaxial Tensile Tests

Medžiagotyra, 2014
Microforming offers a reliable method for mass production of micro parts with low cost and high precision. However, to form micro parts is more difficult than macro parts because of size effects.

Study on Manufacturing Technology of Ag-8.5Au-3.5Pd Fine Alloy Wire

Micromachines, 2021
The performance of Ag-8.5Au-3.5Pd alloy wire after cold deformation and annealing were analyzed by SEM (scanning electron microscope), strength tester and resistivity tester. The processing process and performance change characteristics of Ag-8.5Au-3.5Pd

Effect of defects and specimen size with rectangular cross-section on the tensile properties of additively manufactured components

Virtual and Physical Prototyping, 2020
To evaluate specimen size dependence on the tensile properties of additively manufactured (AM) components, various rectangular specimens, ranging from miniaturised to ASTM standard specimens, are machined from electron beam melted Ti-6Al-4V and used for ...

Speed-mediated properties of schooling [PDF]

Royal Society Open Science, 2019
Collectively moving animals often display a high degree of synchronization and cohesive group-level formations, such as elongated schools of fish. These global patterns emerge as the result of localized rules of interactions.

Microscopic observation of the effects of elongation on the polymer chain dynamics of crosslinked polybutadiene using quasi-elastic γ-ray scattering

Journal of Synchrotron Radiation, 2022
A synchrotron-radiation-based quasi-elastic γ-ray scattering system has been developed that uses time-domain interferometry to observe microscopic polymer dynamics under uniaxial deformation.

Docosahexaenoic acid synthesis from n-3 polyunsaturated fatty acids in differentiated rat brain astrocytes

Journal of Lipid Research, 2001
DHA, the main n-3 PUFA in the brain, is synthesized from n-3 PUFA precursors by astrocytes. To assess the potential of this process to supply DHA for the brain, we investigated whether the synthesis in astrocytes is dependent on DHA availability.

De novo lipogenesis in the differentiating human adipocyte can provide all fatty acids necessary for maturation

Journal of Lipid Research, 2011
The primary products of de novo lipogenesis (DNL) are saturated fatty acids, which confer adverse cellular effects. Human adipocytes differentiated with no exogenous fat accumulated triacylglycerol (TG) in lipid droplets and differentiated normally.

T‐armless tRNAs and elongated elongation factor Tu [PDF]

IUBMB Life, 2007
AbstractMost tRNAs share a common secondary structure containing a T arm, a D arm, an anticodon arm and an acceptor stem. However, there are some exceptions. Most nematode mitochondrial tRNAs and some animal mitochondrial tRNAs lack the T arm, which is necessary for binding to canonical elongation factor Tu (EF‐Tu).
