Interstellar extinction from photometric surveys: application to four high-latitude areas
Open Astronomy, 2018 Information on interstellar extinction and dust properties may be obtained from modern large photometric surveys data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys. It yields a

AutoCal: A software application for calibrating photometric data
South African Journal of Science, 2016 We present a software application for the calibration of stellar magnitudes in the absence of standard stars. It uses an existing algorithm to match stars in the target’s field of view to catalogue entries and computes the average offset between the two ...

Veterinary Clinical Pathology, EarlyView.ABSTRACT Background Monitoring the metabolic changes during the periparturient period is crucial. Objective We aimed to establish reference intervals (RIs) of several serum and plasma biochemical variables in multiparous periparturient Holstein dairy cows. Methods A total of 238 multiparous dry cows from six commercial dairy farms were enrolled.
