Characterization of CrMnNi Steel Powders Obtained via Gas Atomization
steel research international, EarlyView.In this research article, the dependence of the properties of stainless‐steel powders obtained by gas atomization on the particle size is shown. Also, in this article, the morphology, particle size distribution, microstructure, and phase composition, as well as the change in chemical composition and surface tension of various powders fraction, are ...

From Galileo to Hubble: Copernican principle as a philosophical dogma defining modern astronomy [PDF]
, 2018 For centuries the case of Galileo Galilei has been the cornerstone of every major argument against the church and its supposedly unscientific dogmatism.

steel research international, EarlyView.The effect of austenite reversion treatment (ART) on the phase transformation behavior and the mechanical properties of the martensitic–austenitic stainless X16CrNiMnN15‐3‐1‐transformation‐induced‐plasticity‐cast steel is investigated. It is further shown that an ultrahigh‐strength steel with good ductility can be achieved by subsequent partitioning at

Increase in Road Transport Safety - Way to Reduction of External Costs
Communications, 2005 Satellite navigation and prepared navigation system Galileo is the key technology that has to open the gate to new applications. It has to ensure Europe to not be too dependent (in term of economic and safety) on nonmember states of EU, to establish new ...

Empirical consequences of symmetries [PDF]
, 2011 `Global' symmetries, such as the boost invariance of classical mechanics and special relativity, can give rise to direct empirical counterparts such as the Galileo-ship phenomenon. However, a widely accepted line of thought holds that `local' symmetries,

Relativistic positioning: four-dimensional numerical approach in Minkowski space-time
, 2012 We simulate the satellite constellations of two Global Navigation Satellite Systems: Galileo (EU) and GPS (USA). Satellite motions are described in the Schwarzschild space-time produced by an idealized spherically symmetric non rotating Earth.

Infrared spectroscopy of the largest known trans-neptunian object 2001 KX76 [PDF]
, 2002 We report complete near-infrared (0.9-2.4 $\mu$m) spectral observations of the largest know trans-neptunian objects (TNO) 28976 = 2001 KX$_{76}$ taken in two different nights using the new Near Infrared Camera Spectrometer (NICS) attached to the 3.56m Telescopio Nazionale Galileo (TNG).
