Electronic ion energy loss calculations on the basis of the binary encounter approximation
(Elsevier, 1999)
Electronic ion energy loss calculations on the basis of the binary encounter approximation are presented for protons in oxygen, nitrogen and silicon. Calculations using both an analytical approach as well as a Monte Carlo ...
A faraway quasar in the direction of the highest energy Auger event
(IOP PUBLISHING LTD, 2010)
The highest energy cosmic ray event reported by the Auger Observatory has an energy of 148 EeV. It does not correlate with any nearby (z<0.024) object capable of originating such a high energy event. Intrigued by the fact ...
Desalination of water by reverse osmosis using gravitational potential energy and wind energy
(ELSEVIER SCIENCE BV, 2009)
This paper proposes ail alternative configuration to conventional reverse osmosis (RO) desalination systems by incorporating the use of gravitational potential energy. The proposal suggests a model that can be viewed as ...
On the possibility of neutrino flavor identification at the highest energies
(American Physical Society, 2012-12)
High energy astrophysical neutrinos carry relevant information about the origin and propagation of cosmic rays. They can be created as a by-product of the interactions of cosmic rays in the sources and during propagation ...
Total Hadronic Cross-Section Data and the Froissart-Martin Bound

Confusing the extragalactic neutrino flux limit with a neutrino propagation limit
(Iop Publishing Ltd, 2011-10-01)
We study the possible suppression of the extragalactic neutrino flux due to a nonstandard interaction during its propagation. In particular, we study neutrino interaction with an ultra-light scalar field dark matter. It ...
Anisotropy and chemical composition of ultra-high energy cosmic rays using arrival directions measured by the Pierre Auger Observatory
(Institute of Physics - IOPBristol, 2011-06)
The Pierre Auger Collaboration has reported evidence for anisotropy in the distribution of arrival directions of the cosmic rays with energies E > Eth = 5.5 × 1019 eV. These show a correlation with the distribution of ...
Free availability of high-energy foods led to energy over-ingestion and protein under-ingestion in choice-fed broilers
(Wiley, 2015-12)
The objective of this study was to compare energy and protein content of the diet selected by choice-fed broilers with thatof broilers fed a balanced diet. One hundred and eighty 1-day-old male broilers were randomly ...
The flux suppression at the highest energiesLa suppression du flux aux plus hautes énergies
(Elsevier Masson, 2014-03)
Almost half a century ago, Greisen, Zatsepin and Kuz’min (GZK) predicted a “cosmologically meaningful termination” of the spectrum of cosmic rays at energies around 1020 eV due to their interaction with the cosmic microwave ...
The KASCADE-Grande energy spectrum of cosmic rays and the role of hadronic interaction models
(ElsevierAmsterdam, 2014-05)
Previous results obtained by KASCADE-Grande using the QGSjetII-02 hadronic interaction model have shown that the energy spectrum of cosmic rays between '10 POT. 16' eV and '10 POT. 18' eV exhibits a significant hardening ...
