A technique for routinely updating the ITU-R database using radio occultation electron density profiles
(Springer, 2013-06-13)
Well credited and widely used ionospheric models, such as the International Reference Ionosphere or NeQuick, describe the variation of the electron density with height by means of a piecewise profile tied to the F2-peak ...

Uranium isotopes in groundwater occurring at Amazonas State, Brazil
(Elsevier B.V., 2015-03-01)
This paper reports the behavior of the dissolved U-isotopes U-238 and U-234 in groundwater providing from 15 cities in Amazonas State, Brazil. The isotope dilution technique accompanied by alpha spectrometry were utilized ...
Iliac-hepatic arterial bypass for compromised collateral flow during modified Appleby operation for advanced pancreatic cancer
(ELSEVIER SCI LTD, 2009)
Involvement of the celiac trunk and common hepatic artery are two of the most common forms of vascular invasion by tumours of the distal pancreas, and until recently this finding was considered a contra-indication to ...
Probing the properties of Be star discs with spectroastrometry and NLTE radiative transfer modelling: beta CMi
(WILEY-BLACKWELLHOBOKEN, 2012)
While the presence of discs around classical Be stars is well established, their origin is still uncertain. To understand what processes result in the creation of these discs and how angular momentum is transported within ...

Energy dissipation in depth-sensing indentation as a characteristic of the nanoscratch behavior of coatings
(ELSEVIER SCIENCE SA, 2009)
Wear behavior of coatings has usually been described in terms of mechanical properties such as hardness (H) and effective elastic modulus (E*). Alternatively, an energy approach appears as a promising analysis taking into ...
Why goldfish? Merits and challenges in employing goldfish as a model organism in comparative endocrinology research
(Academic Press Inc Elsevier Science, 2018-02)
Goldfish has been used as an unconventional model organism to study a number of biological processes. For example, goldfish is a well-characterized and widely used model in comparative endocrinology, especially in ...
