Modeling Hypersonic Flow over a Spiked Blunt Body Using Adaptive Mesh Refinement on an Overset Grid [PDF]

open access: yesJournal of Applied Fluid Mechanics
In comparison to conventional single-grid methods, grid-adaptive overset techniques offer a strong, flexible, and efficient solution approach for computational fluid dynamics in the modeling of flows with complex interactions.

Acute Neurological Events in Children With Hemoglobin SC Disease: A Multicenter Retrospective Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neurological manifestations in children with hemoglobin SC (HbSC) disease remain insufficiently characterized, particularly regarding acute events. The aim of this study was to describe the spectrum and frequency of acute neurological events in a multicenter cohort of children with HbSC disease.

Ewing Sarcoma in Infants and Children Under 2 Years of Age: A French Retrospective Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Ewing sarcoma, the second most common primary bone cancer in children, requires intensive treatment that may lead to significant long‐term sequelae, particularly in infants. We retrospectively analyzed data from 1621 French patients treated between 1988 and 2015 within the EW88/93/97 or EE99 trials, focusing on 17 infants diagnosed before 24 ...

Heat Convection of Compressible Viscous Fluids. I. [PDF]

open access: yes, 2012
The stationary problem for the heat convection of compressible fluid is considered around the equilibrium solution with the external forces in the horizontal strip domain z_0 < z < z_0 + 1 and it is proved that the solution exists uniformly with

On large bending deformations of transversely isotropic rectangular elastic blocks [PDF]

open access: yes, 2007
In this paper we examine the classical problem of finite bending of a rectangular block of elastic material into a sector of a circular cylindrical tube in respect of compressible transversely isotropic elastic materials.

The Complete Model of Wet Air Analysis in Mine Ventilation Design (CMWAA Method) [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering
The ventilation design of mines is based on fluid dynamics. Air is the main fluid in mining ventilation. This fluid is analyzed by two models: incompressibility and compressibility.
