A three-dimensional model to predict acid treatment processes and its application in complex well-reservoir coupled problems
In the present work, we propose a model to predict treatable size zones for acid reservoir stimulation coupled with the flow in the well. We considered that the lower size scale details are modeled using the P...

The use of a general convected time derivative to compute the Reynolds stress tensor for a compressible turbulent flow
This paper deals with the turbulence closure problem associated with the Reynolds-averaged Navier–Stokes equations for compressible flows. Due to the known limitations faced by the turbulent closure model base...

Acceleration of global N2O emissions seen from two decades of atmospheric inversion
Nitrous oxide (N2O) is the third most important long-lived GHG and an important stratospheric ozone depleting substance. Agricultural practices and the use of N-fertilizers have greatly enhanced emissions of N2O....

Model analysis of the turbulent flows in a convergent–divergent channel and around a sphere
The turbulence closure problem where the objective is to find a model that captures the behavior of the Reynolds stress tensor has proved to be a huge challenge. The commonly employed Boussinesq hypothesis is ...

Observations of atmospheric methane and its stable isotope ratio (δ13C) over the Russian Arctic seas from ship cruises in the summer and autumn of 2015
The results of experimental measurements of atmospheric methane concentrations and its isotopic composition in the Russian Arctic seas in the summer and autumn of 2015 are discussed. The Keeling plot method an...

Quantitative evaluation of evaporation rate during spin-coating of polymer blend films: Control of film structure through defined-atmosphere solvent-casting
Thin films of polymer mixtures made by spin-coating can phase separate in two ways: by forming lateral domains, or by separating into distinct layers. The latter situation (self-stratification or vertical phas...

Prevalence of risk of undernutrition is associated with poor health status in older people in the UK
Objective: To establish the prevalence of the risk of undernutrition, using criteria similar to those used by the Malnutrition Advisory Group (MAG), in people aged 65 y and over, and to identify relationships bet...

Film thickness effects on the distribution of high-molecular-weight heterotelechelic polymers
High-molecular-weight heterotelechelic deuteriopolystyrene, NDPSF, possessing an amine functional group at one end of the chain and a fluorocarbon group at the other was tethered to a silicon substrate by its ...

Partitioning of a heterotelechelic polystyrene to separate interfaces of thin films
Heterotelechelic deuteropolystyrenes have been synthesised with a tertiary amine functionality at one end and a fluorocarbon group at the other end of the polymer chain. A layer of this polymer, circa 120 Å thick...
