Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

FEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Performance of a Detonation Driven Shock Tunnel

, 2005
A detonation driven shock tunnel is useful as a ground test facility for hypersonic flow research. By attaching a convergent section ahead of the primary diaphragm in the driver section, the downstream operation mode became available to generate a high ...

Experimental investigation on converting commercial shock absorber into regenerative shock absorber

Results in Engineering
Commercial shock absorbers dissipate vibration energy induced by road roughness in order to maintain ride quality. However, an appropriate regenerative shock absorber can recover a portion of input energy without changing the initial performance of ...

Effects of hydraulic oil and lubricant additives on dynamic friction properties under various reciprocating sliding conditions

Friction, 2019
The friction characteristics of a shock absorber are very complex because the reciprocating motion is not always identical. In this study a device was developed and used to analyze the dynamic friction characteristics under various reciprocating sliding ...

Performance of a Compact Absorption Heat Pump Containing Microchannel Absorber Components [PDF]

, 2012
Novel microchannel absorbers have been scaled-up and incorporated into a 5-kW-scale ammonia-water absorption heat pump. The planar microchannel absorbers operate with thin wick structures to enhance mass transfer in the absorption channels which are ...
