Context and question: From early Christian times, hunting has been forbidden to Roman Catholic Church clerics. Thus the Corpus Juris Canonici (C. ii, X, De cleric. venat.) says, "We forbid to all servants of God hunting and expeditions through the woods with hounds; and we also forbid them to keep hawks or falcons." The Fourth Council of the Lateran, held under Pope Innocent III, decreed (canon xv): "We interdict hunting or hawking to all clerics." The decree of the Council of Trent is worded more mildly: "Let clerics abstain from illicit hunting and hawking" (Sess. XXIV, De reform., c. xii), which seems to imply that not all hunting is illicit, and canonists generally make a distinction declaring noisy (clamorosa) hunting unlawful, but not quiet (quieta) hunting.
What forbid hunting in the woods with hounds and keeping hawks or falcons?
Answer: Corpus Juris Canonici
Context and question: High-altitude clouds on Neptune have been observed casting shadows on the opaque cloud deck below. There are also high-altitude cloud bands that wrap around the planet at constant latitude. These circumferential bands have widths of 50150 km and lie about 50110 km above the cloud deck. These altitudes are in the layer where weather occurs, the troposphere. Weather does not occur in the higher stratosphere or thermosphere. Unlike Uranus, Neptune's composition has a higher volume of ocean, whereas Uranus has a smaller mantle.
On Neptune, which clouds cast shadows on the cloud deck below it?
Answer: High-altitude clouds
Context and question: The production for sulfidic zinc ores produces large amounts of sulfur dioxide and cadmium vapor. Smelter slag and other residues of process also contain significant amounts of heavy metals. About 1.1 million tonnes of metallic zinc and 130 thousand tonnes of lead were mined and smelted in the Belgian towns of La Calamine and Plombieres between 1806 and 1882. The dumps of the past mining operations leach significant amounts of zinc and cadmium, and, as a result, the sediments of the Geul River contain significant amounts of heavy metals. About two thousand years ago emissions of zinc from mining and smelting totaled 10 thousand tonnes a year. After increasing 10-fold from 1850, zinc emissions peaked at 3.4 million tonnes per year in the 1980s and declined to 2.7 million tonnes in the 1990s, although a 2005 study of the Arctic troposphere found that the concentrations there did not reflect the decline. Anthropogenic and natural emissions occur at a ratio of 20 to 1.
Why does the Geul River contain heavy metals in a significant amount?
Answer:
mining operations leach significant amounts of zinc and cadmium
