Wind farms with counter-rotating wind turbines [PDF]

, 2017
The objective of this study is to assess the effects of using counter-rotating wind turbines on the performance of a wind farm. Large eddy simulations, coupled with the actuator line model, were conducted to investigate flow through a test wind farm with

The Be star o Cas is indeed the primary of a triple system

Astronomy & Astrophysics
Analysis of radial velocities of two narrow absorption components in the Mg II 4481 Å line demonstrated that the secondary of the Be star o Cas is indeed a close binary system composed of two B7 stars orbiting each other with a period of 11.″6604 11

Flux variability of the “10 keV feature” of 4U 0115+63

Astronomy & Astrophysics
Context. X-ray spectra of accretion-powered X-ray pulsars can often be described using a power-law continuum with a high-energy cutoff, which might be further modified by additional spectral components. The Be X-ray binary system 4U 0115+63 is well known

Analysis of mass-transferring binary candidates in the Milky Way

Astronomy & Astrophysics
Mass transfer between stars in binary systems profoundly impacts their evolution, yet many aspects of this process–especially the stability, mass loss, and eventual fate of such systems–remain poorly understood.

Studying the UV Mg II Resonance Lines in 20 Be Stars

Open Astronomy, 2011
Using the GR model, we analyze the UV Mg II resonance lines in the spectra of 20 Be stars of different spectral subtypes, in order to detect the presence of satellite or discrete absorption components. The values of some physical parameters – rotational,

Neurological symptoms among dental assistants: a cross-sectional study

Journal of Occupational Medicine and Toxicology, 2008
Background Dental assistants help the dentist in preparing material for filling teeth. Amalgam was the filling material mostly commonly used in Norway before 1980, and declined to about 5% of all fillings in 2005.

Magnetic field, rotation, and binarity of the first magnetic B[e] star, IRAS 17449+2320

Astronomy & Astrophysics
Context. IRAS 17449+2320 is the first identified magnetic B[e] star. It belongs to a subgroup of peculiar hot B-type stars, called FS CMa stars. All these objects present the B[e] phenomenon, i.e., permitted and forbidden emission lines, and infrared ...
