Efficiency of Electron Transfer Initiated Chemiluminescence [PDF]

open access: yesPhotochemistry and Photobiology, 2013
AbstractAlthough the mechanisms of many chemiluminescence (CL) reactions have been intensively studied, no general model has been suggested to rationalize the efficiency of these transformations. To contribute to this task, we report here quantum yields for some well‐characterized CL reactions, concentrating on recent reports of efficient ...

Planktonic food web structure and trophic transfer efficiency along a productivity gradient in the tropical and subtropical Atlantic Ocean

open access: yesScientific Reports, 2019
Oligotrophic and productive areas of the ocean differ in plankton community composition and biomass transfer efficiency. Here, we describe the plankton community along a latitudinal transect in the tropical and subtropical Atlantic Ocean. Prochlorococcus

Solvent Transfer—Efficiency of Risk Management Measures [PDF]

open access: yesAnnals of Work Exposures and Health, 2017
A series of laboratory simulations were conducted in order to determine the airborne protection that might be afforded by different combinations of workplace exposure controls typically encountered when handling volatile solvents (e.g. solvent transfer). These conditions, referred to as risk management measures (RMMs) under the Registration, Evaluation

Optimal design method of public transit network considering transfer efficiency

open access: yesIET Intelligent Transport Systems, 2023
Improving the sharing rate of public transport and reducing operation costs are key factors affecting the sustainable development of the public transport system. After quantifying the impact of transfer, this study proposes a multi‐objective optimization

Comparison on cooling performance of pre-cooled natural draft dry cooling towers using nozzles spray and wet medium

open access: yesCase Studies in Thermal Engineering, 2021
Evaporative pre-cooling technology improves the cooling performance of natural draft dry cooling towers (NDDCTs) by introducing a certain amount of water into the air entrance. This paper compares the effects of different evaporative pre-cooling systems (

Effects of system-bath entanglement on the performance of light-harvesting systems: A quantum heat engine perspective [PDF]

open access: yes, 2015
We explore energy transfer in a generic three-level system, which is coupled to three non-equilibrium baths. Built on the concept of quantum heat engine, our three-level model describes non-equilibrium quantum processes including light-harvesting energy ...

Extending Oblivious Transfers Efficiently [PDF]

open access: yes, 2003
We consider the problem of extending oblivious transfers: Given a small number of oblivious transfers “for free,” can one implement a large number of oblivious transfers? Beaver has shown how to extend oblivious transfers given a one-way function. However, this protocol is inefficient in practice, in part due to its non-black-box use of the underlying ...

Trophic web structure and ecosystem attributes of a temperate estuarine system (Ria de Aveiro, Portugal)

open access: yesFrontiers in Marine Science, 2015
Estuaries are among the most productive ecosystems and simultaneously among the most threatened by conflicting human activities, which damage their ecological functions.
