Nonlinear problems in flight dynamics involving aerodynamic bifurcations [PDF]
Aerodynamic bifurcation is defined as the replacement of an unstable equilibrium flow by a new stable equilibrium flow at a critical value of a parameter.

Analytical study of the origin and behavior of asymmetric vortices [PDF]
An hypothesis advanced originally to explain computational observations is supported by theoretical considerations: The asymmetric mean flow observed on bodies of revolution at moderate to high angles of attack is the result of a convective instability ...

Socialmedicinsk tidskrift, 2016 Danskerne var i en længere årrække i 1990’erne kendt som et af de mest rygende folk i verden. Cirka 43 procent af den voksne befolkning røg og andelen af rygere var en af de højeste i verden både blandt mænd og kvinder. I flere år var danske kvinder faktisk de mest rygende kvinder i verden.

Nonlinear problems in flight dynamics [PDF]
A comprehensive framework is proposed for the description and analysis of nonlinear problems in flight dynamics. Emphasis is placed on the aerodynamic component as the major source of nonlinearities in the flight dynamic system.

Three-dimensional flows about simple components at angle of attack [PDF]
The structures of three dimensional separated flow about some chosen aerodynamic components at angle of attack are synthesized, holding strictly to the notion that streamlines in the external flow (viscous plus inviscid) and skin friction lines on the ...

Socialmedicinsk tidskrift, 1989 Senare års forskning har genom ett otal rapporter fastslagit tobaksbrukets hälsodestruerande effekter. Detta gäller både genom direkt påverkan hos tobaksbrukande personer men även indirekt genom effekten av sk passiv rökning. Detta drabbar även icke rökande personer i rökiga miljöer, där barn anses vara en speciellt utsatt grupp.Ingen känd ...

Bruk och missbruk: alkohol, narkotika, sniffning och tobak
Socialmedicinsk tidskrift, 1980 Drygt 1/3 av ungdomarna har åtminstone någon gång prövat narkotika. De flesta använde det som 15-åringar. Vid 18 år har 60 % slutat. 30 % har sniffat någon gång, sniffningen kulminerar vid 14 årsåldern. Tobaksbruket tilltar däremot från 15 till 18 år.Vårt intryck är att ungdomarna i sorgligt liten utsträckning är medvetna om alkoholens skadeverkningar

On the Lagrangian Method for Steady and Unsteady Flow [PDF]
A new and general Lagrangian formulation of fluid motion is given in which the independent variables are three material functions and a Lagrangian time, which differs for different fluid particles and is distinct from the Eulerian time.
