Chandra observations of radio galaxies have demonstrated a wide range of complex interactions between their jets and the ambient interstellar/intracluster medium (ISM/ICM). In this paper, we discuss results from Chandra observations of jet/ISM interactions in three nearby radio galaxies: Centaurus A (3.4 Mpc), M87 (16 Mpc), and NGC507 (66.7 Mpc). We present observational details for each object...

This work presents the dynamical and thermal behaviors of a turbulent natural convection flow occurring in cubic cavity with an inner partially heated obstacle. The top, bottom, front back walls are adiabatic other side at imposed uniform temperature. Velocity temperature measurements carried out using Particle Image Velocimetry micro-thermocouples. Boundary layer flows observed both vertical c...

The leakage of hydrogen in a room is key issue safety, and ventilation plays an important role dispersion. usually builds thermal stratification environment due to the low temperature liquid or throttling effect. This study attempts develop fast-computational theoretical model dispersion motion indoor based on classical buoyant jet carry out experimental verify model. research results show that...

A three-dimensional turbulence model was used to determine the effects of animal-generated buoyant forces on the airflow patterns and temperature and airspeed distributions in a ceiling-slot, ventilated, swine grower facility. The model incorporated the Lam-Bremhorst turbulence model for low-Reynolds Number airflow typical of slot-ventilated, livestock facilities. The predicted results from the...

Cutting-edge observations with the 1.6-meter telescope at Big Bear Solar Observatory (BBSO) in California have taken research into the activity of the Sun to new levels of understanding of the structure and evolution of the solar atmosphere at high-resolution spatial and temporal scales. On August 7, 2013 the NST observed active region NOAA 11810 in photospheric and chromospheric wavelengths. T...

We present cosmological magnetohydrodynamic simulations of the formation of a galaxy cluster with magnetic energy feedback from an active galactic nuclei (AGN). We demonstrate that X-ray cavities can be produced by the magnetically dominated jet-lobe system that is supported by a central axial current. The cavities are magnetically dominated and their morphology is determined jointedly by the m...

Inorganic precipitation reactions are known to self-organize a variety of macroscopic structures, including hollow tubes. We discuss recent advances in this field with an emphasis on experiments similar to 'silica gardens'. These reactions involve metal salts and sodium silicate solution. Reactions triggered from reagent-loaded microbeads can produce tubes with inner radii of down to 3 μm. Dist...
