Structural mapping of chloroplast coupling factor

Biochemistry, 1984
Fluorescence resonance energy transfer measurements have been used to investigate the spatial relationships between the nucleotide binding sites and the gamma-subunit of the H+-ATPase from chloroplasts and the orientation of these sites with respect to the membrane surface.

EFFECTIVE INTERNAL LOSS FACTORS AND COUPLING LOSS FACTORS FOR NON-CONSERVATIVELY COUPLED SYSTEMS

Journal of Sound and Vibration, 1998
Abstract What causes negative loss factors in measuring SEA parameters by the power injection method? Analytical results in this paper show that negative loss factors are caused by non-conservative coupling, and non-conservative coupling does not always increase the effective internal loss factors (EILFs).

Coupling factor of H-plane coupled rectangular microstrip antennas

1988 IEEE AP-S. International Symposium, Antennas and Propagation, 2003
Mutual coupling between rectangular half wavelength microstrip antennas fed by a coaxial line at the center of one of the radiating edges is investigated. A closed-form expression for the mutual coupling is developed for the H-plane configuration by which the coupling factor of these antennas may be accurately computed.

Parametrically tunable coupling factor for the weakly coupled resonators

2016 IEEE 11th Annual International Conference on Nano/Micro Engineered and Molecular Systems (NEMS), 2016
In this paper, we presented the electrostatic tuning functions of the coupling factor for the weakly coupled resonators (WCRs) for the first time. A WCRs system with two mechanical coupled double-ended-tuning-fork (DETF) resonators is designed, fabricated and tested to verify the tuning theory.

Coupled Biogeochemical Cycling and Controlling Factors

2003
The changing climate of the planet is closely linked to biogeochemical processes in the oceans with important feedbacks between oceanic, atmospheric and terrestrial components of the earth system. This chapter identifies key processes that mediate the response of marine ecosystems to a changing environment and recommends implementation strategies for ...

[85] Coupling factor 4 (F4)

1967
Publisher Summary This chapter discusses the coupling factor 4 (F 4 ). A- and P-particles require the addition of F 4 for respiratory chain phosphorylation and for all reactions associated with oxidative phosphorylation that involve a transphosphorylation step with ATP.

Coupling Factors in Oxidative Phosphorylation

1978
A classical approach to the study of the mechanism of multienzyme systems involves resolution of the constituent parts and reconstitution of the system from the purified components. Application of this approach to the study of the mechanism of oxidative phosphorylation was first initiated in David Green’s laboratory.

[47] Coupling factors—An overview

1979
Publisher Summary Attempts to fractionate the mitochondrial oxidative phosphorylation system have met with some success and hold promise of contributing further significant and decisive data to the understanding of the mechanism of energy transduction in mitochondria. The reconstituted systems have two parts. One is the submitochondrial particle (SMP)

[84b] Coupling factor 3 (F3)

1967
Publisher Summary This chapter discusses the coupling factor 3 (F 3 ). F 3 is measured with A-particles by the stimulation of the ATP-linked reduction of DPN by succinate in the presence of F 1 or by the increase of the P:O ratio in the presence of F 1 and F 2 . F 3 , 1-50 μl of the enzyme solution is used for assay.
