Statistical Review of the Italian Gas Transmission System Operator under Conditions of the COVID-19 Pandemic and the Supply Restriction from the Russian Federation

open access: yesGases, 2022
The coronavirus pandemic caused a crisis in industrial economies, enforcing public concern. The first case of the infection in Europe occurred in Italy.

Modulational Instability of Ion-Acoustic Waves and Associated Envelope Solitons in a Multi-Component Plasma

open access: yesGases, 2021
A generalized plasma model with inertial warm ions, inertialess iso-thermal electrons, super-thermal electrons and positrons is considered to theoretically investigate the modulational instability (MI) of ion-acoustic waves (IAWs).

Uniform electron gases

open access: yes, 2012
We show that the traditional concept of the uniform electron gas (UEG) --- a homogeneous system of finite density, consisting of an infinite number of electrons in an infinite volume --- is inadequate to model the UEGs that arise in finite systems.

Thermodynamics of sustaining gases in the roughness of submerged superhydrophobic surfaces

open access: yes, 2015
Rough surfaces submerged in a liquid can remain almost dry if the liquid does not fully wet the roughness and gases are sustained in roughness grooves. Such partially dry surfaces can help reduce drag or enhance boiling.

Inflation and Brane Gases [PDF]

open access: yes, 2004
We investigate a new way of realizing a period of cosmological inflation in the context of brane gas cosmology. It is argued that a gas of co-dimension one branes, out of thermal equilibrium with the rest of the matter, has an equation of state which can

Many-Body Physics with Ultracold Gases

open access: yes, 2007
This article reviews recent experimental and theoretical progress on many-body phenomena in dilute, ultracold gases. Its focus are effects beyond standard weak-coupling descriptions, like the Mott-Hubbard-transition in optical lattices, strongly ...

An investigation of the accuracy of numerical solutions of Boltzmann's equations for electron swarms in gases with large inelastic cross sections [PDF]

open access: yes, 1979
Copyright @ 1979 CSIROA Monte Carlo simulation technique has been used to test the accuracy of electron energy distribution functions and transport coefficients calculated using conventional numerical solutions of Boltzmann's equation based on a two-term

Rapidly Rotating Fermi Gases

open access: yes, 2000
We show that the density profile of a Fermi gas in rapidly rotating potential will develop prominent features reflecting the underlying Landau level like energy spectrum.

The Role of Invasive Procedures in the Treatment of Complicated Gastrointestinal Graft‐Versus‐Host Disease in Pediatric Patients

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Gastrointestinal graft‐versus‐host disease (GI GVHD) following hematopoietic stem cell transplant is typically managed with medical therapy, but surgery and angioembolization may be warranted in selected cases with life‐threatening complications.

Competition between Vortex Unbinding and Tunneling in an Optical Lattice

open access: yes, 2007
We study a system of two-dimensional Bose gases trapped in minima of a deep one-dimensional optical lattice potential. Increasing the tunneling amplitude between adjacent gases drives a deconfinement transition to a phase where coherence is established ...
