Effect of a Local Absorber in Absorber Theory

open access: yes, 1973
IN a recent experiment Partridge1 found a null result to 1 part in 108 for the effect of a local absorber on the power emitted by a source. This result is interpreted in the framework of absorber theory as setting some constraints on the absorptive ...

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

open access: yes, 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 ...

Spectrum Absorbency of Metamaterial Perfect Absorber

open access: yesThe International Journal of Integrated Engineering, 2022
A triple-band metamaterial perfect absorber was introduced. The single and simple structure based on gold-bar shaped was designed on the 0.018λ Taconic TLY-5. The gold-bar shaped was designed horizontal initially was then being rotated anti-clockwise from0oto 90oto analyze and understand the change of absorption graph.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Economic Shocks and Exchange Rate as a Shock Absorber in Indonesia and Thailand [PDF]

open access: yes
This study investigates the requirement for the exchange rate to be a shock absorber in Indonesia and Thailand from 1986 to 2007. In general, we find that the economic shocks have predominantly been asymmetric relative to the US and the Japanese ...

Numerical and Experimental Modelling of a Wave Energy Converter Pitching in Close Proximity to a Fixed Structure

open access: yesJournal of Marine Science and Engineering, 2019
Free-floating bodies are commonly modelled using Cummins’ equation based on linear potential flow theory and including non-linear forces when necessary.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Optimisation of dynamic vibration absorbers to minimise kinetic energy and maximise internal power dissipation

open access: yes, 2011
The tuning of a dynamic vibration absorber is considered such that either the kinetic energy of the host structure is minimised or the power dissipation within the absorber is maximised.

Design of novel broadband absorber based on resistive film

open access: yesZhongguo Jianchuan Yanjiu, 2021
Objectives In order to improve the performance of traditional absorbing materials, a high-absorptivity broadband absorber is designed. Methods The absorber consists of a resistive film, dielectric substrate and metal ground plate. The element unit of the

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.
