ERRATUM A third possible explanation for the X-ray emission from the z = 2.156 radio galaxy 1138−262 is thermal emission from a very dense, sub-cluster 'halo', perhaps associated with the (forming) cD galaxy on a scale ≤ 100 kpc. For instance, increasing the gas density from 0.01 cm −3 to 0.1 cm −3 would decrease the required hot gas mass by the same factor, and could possibly alleviate constra...

Hot pressing process is very popular for thin plates in metal forming. However, the process mechanism for thick plates of high strength steel at high temperature deserves more investigations. The process is characterized by thermo-mechanical behaviors, three-dimensional unsteady deformations and high nonlinearity. In this paper, the model of the process for manufacturing large and thick blades ...

Cosmological hydrodynamic simulations predict that the low redshift universe comprises a web of warm–hot intergalactic gas and galaxies, with groups of galaxies and clusters forming at dense knots in these filaments. Our own Galaxy being no exception is also expected to be surrounded by the warm–hot intergalactic medium, filling the Local Group. Some theoretical models also predict the existenc...

The incremental sheet metal forming (ISMF) process is a new and flexible method that is well suited for small batch production or prototyping. This paper studies the use of the finite element method in the incremental forming process of AA1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...

We investigate the role of supernova (SN)-driven galactic winds in the chemical enrichment of the intracluster medium (ICM). Such outflows on galactic scales have their origin in huge star forming regions and expel metal enriched material out of the galaxies into their surroundings as observed, for example, in the nearby starburst galaxy NGC 253. As massive stars in OB-associations explode sequ...

For modern Gas sensors, high sensitivity and low power are expected. This paper discusses design, simulation and fabrication of new Micromachined Thermal Converters (MTCs) based on GaAs developed for Gas sensors. Metal oxide gas sensors generally work in high temperature mode that is required for chemical reactions to be performed between molecules of the specified gas and the surface of sensin...

the growth of the electrical energy consumption form one side and the bounded available fossil fuel and other limitations from the other side, makes the thermal power plants upgrading as a main demand in the world. decreasing the internal energy consumption, increasing the performance and the output power with the minimum costs are the important targets of the power plants retrofitting. nowaday...

An obligatory heterofermentative lactic acid bacterium Lactobacillus wasatchii sp. nov. isolated from gassy Cheddar cheese was studied for growth, gas formation, salt tolerance and survival against pasteurization treatments at 63°C and 72°C. Initially, Lb. wasatchii was thought to only use ribose as a sugar source and we were interested in whether it could utilize galactose. Experiments to dete...

We review the evidence for cosmic ray acceleration in the superbubble/hot phase of the interstellar medium, and discuss the implications for the composition of cosmic rays and the structure and evolution of the interstellar medium (ISM). We show that the bulk of the galactic supernovae, their expanding remnants, together with their metal-rich grain and gas ejecta, and their cosmic ray accelerat...
