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 ...

Monomer concentration profile in the depletion region

open access: yesJournal de Physique, 1988
We study by Monte Carlo simulation the monomer concentration profile of the dilute solution of linear chain polymers in the depletion region near an impenetrable but otherwise non-interacting wall. Only the case of a good solvent is treated here but we allow both for flexible and semi-flexible chains.

THE DEPLETION OF WATER DURING DISPERSAL OF PLANET-FORMING DISK REGIONS [PDF]

open access: yesThe Astrophysical Journal, 2017
ABSTRACT We present a new velocity-resolved survey of 2.9 μm spectra of hot H2O and OH gas emission from protoplanetary disks, obtained with the Cryogenic Infrared Echelle Spectrometer at the VLT (R ∼ 96,000). With the addition of archival Spitzer-IRS spectra, this is the most comprehensive spectral data set of water vapor emission from ...

Nano-grain depletion in photon-dominated regions

open access: yesAstronomy & Astrophysics, 2022
Context. Carbonaceous nano-grains play a fundamental role in the physico-chemistry of the interstellar medium (ISM) and especially of photon-dominated regions (PDRs). Their properties vary with the local physical conditions and affect the local chemistry and dynamics. Aims.

Impact of Silicon Substrate with Low Resistivity on Vertical Leakage Current in AlGaN/GaN HEMTs

open access: yesApplied Sciences, 2019
The role of low-resistivity substrate on vertical leakage current (VLC) of AlGaN/GaN-on-Si epitaxial layers has been investigated. AlGaN/GaN high-electron-mobility transistors (HEMTs) grown on both p-type and n-type Si substrates with low resistivity are

Imaging and EISCAT radar measurements of an auroral prebreakup event [PDF]

open access: yesAnnales Geophysicae, 1996
The results of coordinated EISCAT and TV-camera observations of a prebreakup event on 15 November 1993 have been considered. The variations of the luminosity of two parallel auroral arcs, plasma depletion on the poleward edge of one of these arcs as ...

Massive crop expansion threatens agriculture and water sustainability in northwestern China

open access: yesEnvironmental Research Letters, 2022
Northwestern China (NWC) is among the major global hotspots undergoing massive terrestrial water storage (TWS) depletion. Yet driver(s) underlying such region-wide depletion remain controversial, i.e.
