Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Iraq currently faces a significant electricity deficit estimated at approximately 18 000 MW, resulting in frequent and sometimes prolonged power outages that disrupt both economic activities and social life. The widening gap between energy supply and demand, combined with environmental concerns associated with fossil fuel consumption ...

Artificial perturbations of the radiation belts [PDF]
, 1972 A review is given of the properties of the radiation belts which have been produced by high-altitude nuclear detonations. The low-yield, Argus devices, 1, 2, and 3, and the Soviet test of 1 November 1962 injected intense electron fluxes in narrow L-shell

Collisions and drag in debris discs with eccentric parent belts [PDF]
, 2017 Context: High-resolution images of circumstellar debris discs reveal off-centred rings that indicate past or ongoing perturbation, possibly caused by secular gravitational interaction with unseen stellar or substellar companions.

Spatial metrics in fire ecology: seeking consistency amidst complexity
Biological Reviews, EarlyView.ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

The discovery of trapped energetic electrons in the outer cusp [PDF]
, 1998 We report on the POLAR/CEPPAD discovery of a trapped, 60°\u3cθ\u3c120° pitch angle electron population in the outer cusp (7−9+ Re), whose energetic electron component extends from below 30 keV to ∼2 MeV.

Advances in Triboelectric Nanogenerators With Rotating Structure
Carbon Energy, EarlyView.The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

Radiation belt probes launched [PDF]
Eos, Transactions American Geophysical Union, 2012 Storms on Earth delayed by only a few days the launch of NASA's Radiation Belt Storm Probes (RBSP), which blasted off on 30 August for a 2‐year tour to explore the Van Allen radiation belts. The two satellites will help scientists learn about the processes that affect electrons and ions in the donut‐shaped belts and how the belts change in the context ...

Jupiter's Radiation Belts and Upper Atmosphere [PDF]
Symposium - International Astronomical Union, 1974 Models of Jupiter's radiation belts have been constructed to determine the distribution of particles and their energies which will produce the observed decimetric radio emission. Data on the spectrum and the variation of emission with Jovian longitude have been used to show that the relativistic particles have a nearly isotropic distribution with high ...
