Market Power and Technological Bias: The Case of Electricity Generation [PDF]

open access: yes, 2006
It is difficult to elminated all market power in electricity markets and it is therefore frequently suggested that some market power should be tolerated: extra revenues contribute to fixed cost recovery,facilitate investment and increase security of ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Reforming Natural Gas for CO2 Pre-Combustion Capture in Trinary Cycle Power Plant

open access: yesEnergies
Today, most of the world’s electric energy is generated by burning hydrocarbon fuels, which causes significant emissions of harmful substances into the atmosphere by thermal power plants. In world practice, flue gas cleaning systems for removing nitrogen

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Hydropower Plants and Their Problems [PDF]

open access: yes, 2017
Approximately 23% of the world electric power is produced by hydroelectric power plants (HPP). This kind of power stations convert the kinetic energy of the falling water into the mechanical energy of the turbine's rotation, and the turbine drives the

Species–area relationships in continuous vegetation : evidence from Palaearctic grasslands [PDF]

open access: yes, 2019
Aim: Species-area relationships (SARs) are fundamental scaling laws in ecology although their shape is still disputed. At larger areas power laws best represent SARs.

Power systems with high renewable energy sources: A review of inertia and frequency control strategies over time [PDF]

open access: yes, 2020
Traditionally, inertia in power systems has been determined by considering all the rotating masses directly connected to the grid. During the last decade, the integration of renewable energy sources, mainly photovoltaic installations and wind power ...

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
