Anthropogenic greenhouse gas emissions need to be cut limit climate change. Thus, universities, in the same way as citizens and companies, are starting raise awareness about this issue take action reduce their carbon footprint. Centrale Nantes, a French “Grande école”, initiated low transition with calculation of 2018 footprint university. This report presents an individual estimator developed ...
The means by which homing pigeons determine the direction to their home loft when released in unfamiliar territory remains a mystery. Hypotheses involving the sun (Matthews, 1953, 1955), Coriolis force and the earth's magnetic field (Yeagley, 1947, 1951), inertial cues (Barlow, 1964, 1966), infrasound (Kreithen & Quine, 1979), have been advanced but currently there is no strong empirical suppor...
A portion of the Fly's Eye II detector has been recording Cherenkov flashes since 1987 in the declination band 10° < ä < 50°. This band includes Cyg X-3, Her X-1, the Crab nebula, and Cyg X-1. The threshold energy is approximately 70 TeV. Observed and expected shower counts are available for all points in this declination band on a nightly basis. Searching for steady, transient, or sporadic poi...

Abstract. The historical magnetic observatory Clementinum operated in Prague from 1839 to 1926. data the yearbooks that recorded observations at have recently been digitized and were subsequently converted, this work, into physical units of International System Units (SI). Introducing a database geomagnetic source is part our paper. Some controversial are also analysed here. In original sources...
