Implications of Variability Patterns observed in TeV Blazars on the Structure of the Inner Jet [PDF]

, 2002
The recent long look X-ray observations of TeV blazars have revealed many important new features concerning their time variability. In this paper, we suggest a physical interpretation for those features based on the framework of the internal and external

Restricted fluid bolus versus current practice in children with septic shock: the FiSh feasibility study and pilot RCT

Health Technology Assessment, 2018
Background: There has been no randomised controlled trial (RCT) of fluid bolus therapy in paediatric sepsis in the developed world despite evidence that excess fluid may be associated with harm.

Merger of binary neutron stars of unequal mass in full general relativity [PDF]

, 2003
We present results of three dimensional numerical simulations of the merger of unequal-mass binary neutron stars in full general relativity. A $\Gamma$-law equation of state $P=(\Gamma-1)\rho\epsilon$ is adopted, where $P$, $\rho$, $\varep$, and $\Gamma$

XMM-Newton X-ray Observations of the Wolf-Rayet Binary System WR 147 [PDF]

, 2007
We present results of a 20 ksec X-ray observation of the Wolf-Rayet (WR) binary system WR 147 obtained with XMM-Newton. Previous studies have shown that this system consists of a nitrogen-type WN8 star plus an OB companion whose winds are interacting to ...

Effect of the fluidic injection on the flow of a converging-diverging conical nozzle

International Journal of Energetica, 2020
The flow in an Over-Expanded Nozzle is subjected to shock waves leading to the unsteady separation of the boundary layer. Free detachment may be followed by a restricted detachment.

On Reflection of Shock Waves from Boundary Layers [PDF]

, 1952
Measurements of the reflection characteristics of shock waves from a flat surface with a laminar and turbulent boundary layer are presented. The investigations were carried out at Mach numbers from about 1.3 to 1.5 and a Reynolds number of 0.9 x 10^4.
