Abstract This paper carried out the environmental and economic evaluation for hydrogen storage technologies on sedan with Type 3 4 high-pressured cryogenic vessels based life cycle analysis (LCA) method. It is found that vessel manufacture emits minimum greenhouse gas (GHG) 5539 kgCO2 eq, which lower than of 7219 eq 135 000 in their whole cycle. The shows high-pressure has lowest cost 10.4 US$/...

This paper presents a " man on the street " view of the current status of the spectral cross calibration between the XMM-Newton EPIC, Chandra ACIS-S3, ASCA SIS and GIS, and ROSAT PSPC instruments. Using publicly released software for the extraction of spectra and the production of spectral redistribution response matrices and effective areas, the spectral fits of data from three astronomical ob...

We present new proper motion measurements of optically emitting oxygen-rich knots supernova remnant 1E 0102.2-7219 (E0102), which are used to estimate the remnant's center expansion and age. Four epochs high resolution Hubble Space Telescope images spanning 19 yr were retrieved analyzed. found a robust alpha=1:04:02.48 delta=-72:01:53.92 (J2000) with 1-sigma uncertainty 1.77 arcseconds using 45...
