Large-scale Hydrogen Production

There is a growing need for hydrogen and a future hydrogen economy is high on the political agenda. But where should the hydrogen come from? The “sustainable” routes are still too expensive. Steam reforming of hydrocarbons is the most feasible route today. If CO2-sequestration is accepted, fossil fuels may play an important role in a starting future “hydrogen economy”. This will happen by use o...

construction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers

the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...

The large-scale bias of the hard X-ray background

Recent deep X-ray surveys combined with spectroscopic identification of the sources have allowed the determination of the rest-frame 2− 8 keV luminosity as a function of redshift. In addition, an analysis of the HEAO1 A2 2 − 10 keV full-sky map of the X-ray background (XRB) reveals clustering on the scale of several degrees. Combining these two results in the context of the currently favored ΛC...

Gravity and Large-Scale Nonlocal Bias

For Gaussian primordial fluctuations the relationship between galaxy and matter overdensities, bias, is most often assumed to be local at the time of observation in the large-scale limit. This hypothesis is however unstable under time evolution, we provide proofs under several (increasingly more realistic) sets of assumptions. In the simplest toy model galaxies are created locally and linearly ...
