Equatorial F-region plasma depletion drifts: latitudinal and seasonal variations [PDF]

open access: yesAnnales Geophysicae, 2003
The equatorial ionospheric irregularities have been observed in the past few years by different techniques (e.g. ground-based radar, digisonde, GPS, optical instruments, in situ satellite and rocket instrumentation), and its time evolution and ...

Oil Price and Energy Depletion Nexus in GCC Countries: Asymmetry Analyses

open access: yesEnergies, 2020
Oil price has played a prominent role in oil exporter economies and may also affect energy depletion in oil-dependent countries. Considering asymmetry, the relationship between oil price (OP) and energy depletion has been investigated in the Gulf ...

Luminous Infrared Galaxies With the Submillimeter Array. III. The Dense Kiloparsec Molecular Concentrations of Arp 299 [PDF]

open access: yes, 2012
We have used high resolution (~2.3") observations of the local (D = 46 Mpc) luminous infrared galaxy Arp 299 to map out the physical properties of the molecular gas which provides the fuel for its extreme star formation activity. The 12CO J=3-2, 12CO J=2-

Characterization ofProchlorococcusclades from iron-depleted oceanic regions [PDF]

open access: yesProceedings of the National Academy of Sciences, 2010
Prochlorococcusdescribes a diverse and abundant genus of marine photosynthetic microbes. It is primarily found in oligotrophic waters across the globe and plays a crucial role in energy and nutrient cycling in the ocean ecosystem. The abundance, global distribution, and availability of isolates makeProchlorococcusa model system for understanding marine
