Spatial DNS of an Isothermal Flat Plate Supersonic Turbulent Boundary Layer with/out Impinging Shock Wave

open access: yesJournal of Fluid Science and Technology, 2011
Spatial direct numerical simulation results are presented for transitional/turbulent supersonic isothermal flat plate boundary layers at M = 2.0 and impinging shock wave-boundary layer interactions.

A DNS, mint bizonyíték felhasználása a büntetőeljárás során

open access: yes, 2014
"Az igazságügyi genetika, mint különálló tudományterület, nagykorú lett. Ez a nagykorúság nemcsak abból fakad, hogy törvényszéki eljárásban genetikai vizsgálatot először 28 évvel ezelőtt, 1985-ben alkalmaztak Angliában, hanem abból is, hogy mára a világ ...

Hevea brasiliensis seeds: A novel sustainable feedstock for ethanol production

open access: yesVietnam Journal of Chemistry, EarlyView.
Abstract The rubber tree (Hevea brasiliensis) is cultivated on a large scale mainly for the extraction of latex in Brazil and Southeast Asia, also generating large quantities of seeds. These seeds currently do not have large‐scale applications and may thus be considered as a residue.

Large-Scale Flow Structure in Turbulent Poiseuille Flows at Low-Reynolds Numbers

open access: yesJournal of Fluid Science and Technology, 2012
Direct numerical simulations of a spectral method are performed to study the turbulent channel flow at the low-Reynolds numbers, where the quasi-laminar and turbulent regions simultaneously appear and form the stripe pattern, which is floated downstream ...

Affordances, dread, and online fraud: Exploring and advancing social learning theory in online contexts

open access: yesCriminology, EarlyView.
Abstract We investigate how the affordances of an online context shape the processes of social learning. Using a dataset of more than 11,000 posts from the fraud subdread on the dark web forum Dread, we examine how affordances of platform governance, connectivity, anonymity, invisibility, asynchronicity, and limited oversight influence the components ...

Salivary Alpha Amylase Enzyme as a Stress Parameter: Establishment and Comparison of Laboratory Methods

open access: yesNamık Kemal Tıp Dergisi
Aim: Salivary alpha (a)-amylase enzyme is a biomarker used to measure sympathetic nervous system activity. This study aimed to establish three existing methods for measuring salivary a-amylase enzyme activity in the laboratory and to compare these ...

Study of Transition to Turbulence in a Supersonic Boundary Layer Using DNS and Transition Prediction

open access: yesJournal of Fluid Science and Technology, 2007
The current understanding of supersonic boundary layer transition is reviewed in this paper. The material focuses on bypass transition in a plane supersonic boundary layer. Recent advances in DNS and engineering prediction of transition are discussed. It

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

The effect of upstream disturbance on the angle of sound emission in a supersonic round jet

open access: yesJournal of Fluid Science and Technology, 2014
The three-dimensional time-dependent compressible Navier-Stokes equations are numerically solved to study acoustic emission mechanisms in a supersonic round jet at high convective Mach numbers. A 5th-order compact upwind algorithm developed by Deng et al.
