What was important to preachers?, Context: Doctrinal development has had an important place in the restoration of the Preachers. Several institutions, besides those already mentioned, played important parts. Such is the Biblical school at Jerusalem, open to the religious of the order and to secular clerics, which publishes the Revue Biblique. The faculty of theology at the University of Fribourg, confided to the care of the Dominicans in 1890, is flourishing, and has about 250 students. The Pontificium Collegium Internationale Angelicum, the future Pontifical University of Saint Thomas Aquinas, Angelicum established at Rome in 1908 by Master Hyacinth Cormier, opened its doors to regulars and seculars for the study of the sacred sciences. In addition to the reviews above are the Revue Thomiste, founded by Père Thomas Coconnier (d. 1908), and the Analecta Ordinis Prædicatorum (1893). Among numerous writers of the order in this period are: Cardinals Thomas Zigliara (d. 1893) and Zephirin González (d. 1894), two esteemed philosophers; Alberto Guillelmotti (d. 1893), historian of the Pontifical Navy, and Heinrich Denifle, one of the most famous writers on medieval history (d. 1905).[citation needed]

What is the area of expertise of scientists who want to measure radiance from vegetation canopies?, Context: Oxygen presents two spectrophotometric absorption bands peaking at the wavelengths 687 and 760 nm. Some remote sensing scientists have proposed using the measurement of the radiance coming from vegetation canopies in those bands to characterize plant health status from a satellite platform. This approach exploits the fact that in those bands it is possible to discriminate the vegetation's reflectance from its fluorescence, which is much weaker. The measurement is technically difficult owing to the low signal-to-noise ratio and the physical structure of vegetation; but it has been proposed as a possible method of monitoring the carbon cycle from satellites on a global scale.

Who was related to Ancilla?, Context: His sister Ancilla would soon be diagnosed with stomach cancer in the early 1950s. Roncalli's last letter to her was dated on 8 November 1953 where he promised to visit her within the next week. He could not keep that promise, as Ancilla died on 11 November 1953 at the time when he was consecrating a new church in Venice. He attended her funeral back in his hometown. In his will around this time, he mentioned that he wished to be buried in the crypt of Saint Mark's in Venice with some of his predecessors rather than with the family in Sotto il Monte.
