We use new and archival Chandra data to investigate the X-ray emission from a large sample of compact hot spots of FR II radio galaxies and quasars from the 3C catalog. We find that only the most luminous hot spots tend to be in good agreement with the predictions of a synchrotron self-Compton model with equipartition magnetic fields. At low hot spot luminosities inverse Compton predictions are...

Respirator performance rating tables have been constructed for hot, humid (29 degrees C, 95% RH); hot, dry (49 degrees C, 30% RH); and cold, dry (-32 degrees C, 70% RH) conditions. These tables convey expected wearer performance percentages compared to unmasked workers for various mask elements and work rates. The hot, humid condition was found to be the most severe overall. Many table entries ...

in this work, effects of homogenization time of 3 to 13 h at 1200 °c on the grain refinement of as-cast aisi 301 stainless steel after different hot rolling conditions were investigated. the results showed that the minimum grain size of 16±7 mm was achieved when homogenization took place at 1200 °c for 9 h followed by hot rolling at temperature range of 1000–1200 °c with strain of 0.8 and strai...

We present the first high-resolution three-dimensional simulations of the deflagration phase of Type Ia supernovae that treat the entire massive white dwarf. We report the results of simulations in which ignition of the nuclear burning occurs slightly off-center. The subsequent evolution of the nuclear burning is surprisingly asymmetric with a growing bubble of hot ash rapidly rising to the ste...

The ongoing characterization of hot Jupiters has motivated a variety of circulation models of their atmospheres. Such models must be integrated starting from an assumed initial state, which is typically taken to be a wind-free, rest state. Here, we investigate the sensitivity of hot-Jupiter atmospheric circulation models to initial conditions. We consider two classes of models—shallow-water mod...

Wireless networks are now proliferating due to the success of the IEEE 802.11b protocol, also known as “Wi-Fi” (Wireless Fidelity). A Wi-Fi network is characterized by a set of base stations (also called access points) placed throughout the environment and connected to the traditional wired LANs. This technology allows nomadic users a broadband access to the Internet if they are in the transmis...
