Radial velocity eclipse mapping of exoplanets [PDF]

open access: yes, 2015
Planetary rotation rates and obliquities provide information regarding the history of planet formation, but have not yet been measured for evolved extrasolar planets.

Goaf gas flow modelling in 6km long longwall panel [PDF]

open access: yesPodzemni Radovi, 2017
Understanding the goaf gas distribution in the start-up areas and in 6km long retreat panel is critical for developing gas management and spontaneous combustion (sponcom) control strategies.

Large Eddy Simulation of Rotationally Induced Ingress and Egress around an Axial Seal between Rotor and Stator Disks

open access: yesEnergies, 2023
In gas turbines, the hot gas exiting the combustor can have temperatures as high as 2000 °C, and some of this hot gas enter into the space between the stator and rotor disks (wheelspace).

UBVRI photopolarimetry of the long period eclipsing AM Herculis binary V1309 [PDF]

open access: yes, 2002
We report simultaneous UBVRI photo-polarimetric observations of the long period (7.98 h) AM Her binary V1309 Ori. The length and shape of the eclipse ingress and egress varies from night to night. We suggest this is due to the variation in the brightness

Numerical Investigation of Unsteady Interaction between Rim Seal Flow and Upstream Vane

open access: yesXibei Gongye Daxue Xuebao, 2019
To investigate unsteady interaction mechanism between the rim seal flow in turbine stator-rotor cavity and main flow, detailed unsteady numerical simulations of the flow field and unsteady characteristic of the vane were conducted under different rim ...

Mass Transfer, Transiting Stream and Magnetopause in Close-in Exoplanetary Systems with Applications to WASP-12

open access: yes, 2010
We study mass transfer by Roche lobe overflow in close-in exoplanetary systems. The planet's atmospheric gas passes through the inner Lagrangian point and flows along a narrow stream, accelerating to 100-$200\kms$ velocity before forming an accretion ...

Relativistic Fermi acceleration with shock compressed turbulence [PDF]

open access: yes, 2005
This paper presents numerical simulations of test particle Fermi acceleration at relativistic shocks of Lorentz factor Gamma_sh = 2-60, using a realistic downstream magnetic structure obtained from the shock jump conditions.

Psychological Safety Among Interprofessional Pediatric Oncology Teams in Germany: A Nationwide Survey

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Psychological safety (PS) is essential for teamwork, communication, and patient safety in complex healthcare environments. In pediatric oncology, interprofessional collaboration occurs under high emotional and organizational demands. Low PS may increase stress, burnout, and adverse events.

Quantitative NMR monitoring of liquid ingress into repellent heterogeneous layered fabrics [PDF]

open access: yes, 2008
Fabrics which are water repellent and repellent to other liquids are often constructed using multiple layers of material. Such a construction is preferable to a single layer of a liquid-repellent textile because, under the action of an applied pressure ...
