The City of God is marked by people who forgo earthly pleasure to dedicate themselves to the eternal truths of God, now revealed fully in the Christian faith. The Earthly City, on the other hand, consists of people who have immersed themselves in the cares and pleasures of the present, passing world. [4]
Actium. Coordinates: 38.953°N 20.768°E. A map showing the Battle of Actium. Actium or Aktion (Ancient Greek: Ἄκτιον) was a town on a promontory in ancient Acarnania at the entrance of the Ambraciot Gulf, off which Octavian gained his celebrated victory, the Battle of Actium, over Antony and Cleopatra, on September 2, 31 BCE.
Actinium is a chemical element; it has symbol Ac and atomic number 89. It was first isolated by Friedrich Oskar Giesel in 1902, who gave it the name emanium; the element got its name by being wrongly identified with a substance André-Louis Debierne found in 1899 and called actinium. The actinide series, a set of 15 elements between actinium ...
The actinide series is a group of chemical elements with atomic numbers ranging from 89 to 102, [note 1] including notable elements such as uranium and plutonium.The nuclides (or isotopes) thorium-232, uranium-235, and uranium-238 occur primordially, while trace quantities of actinium, protactinium, neptunium, and plutonium exist as a result of radioactive decay and (in the case of neptunium ...
Actinium-227 (half-life 21.77 years) occurs in all uranium ores, but in small quantities. One gram of uranium (in radioactive equilibrium) contains only 2 × 10 −10 gram of 227 Ac. [30] [57] Actinium-228 is a member of the radioactive thorium series formed by the decay of 228 Ra; [60] it is a β − emitter with a half
Actinium-227 is the most stable isotope of actinium, with a half-life of 21.772 years. It mainly (98.62%) undergos beta decay, but sometimes (1.38%) it will undergo alpha decay instead. [1] 227 Ac is a member of the actinium series. It is found only in traces in uranium ores – one tonne of uranium in ore contains about 0.2 milligrams of 227 Ac.
Yes. Mashkan-shapir (modern Tell Abu Duwari, Al Qadisyah Governorate, Iraq) was an ancient tell roughly 30 kilometres (19 mi) north of Nippur and around 90 miles (140 km) southeast of Baghdad. The city god of Mashkan-shapir was Nergal and a temple named Meslam dedicated to him was built there. It is about 20 kilometers south of ancient Malgium.
Cobá took its place in Maya culture no earlier than 100 B.C., and enjoyed a continuous life as a city until about 1,200 A.D. Known as the “city of chopped water,” the site may have had up to ...
