The Intensity 7 ( 震度7, Shindo 7) is the maximum intensity in the Japan Meteorological Agency seismic intensity scale, covering earthquakes with an instrumental intensity (計測震度) of 6.5 and up. [ 15] At Intensity 7, it becomes impossible to move at will. [ 13] The intensity was created following the 1948 Fukui earthquake.
This is especially true for Healthy life expectancy, the definition of which criteria may change over time, even within a country. For example, Canada is a country with a fairly high overall life expectancy at 81.63 years; however, this number decreases to 75.5 years for Indigenous people in the country. [4]
Chromium is the 21st [38] most abundant element in Earth's crust with an average concentration of 100 ppm. It is also the seventh most abundant element on earth. [39] Chromium compounds are found in the environment from the erosion of chromium-containing rocks, and can be redistributed by volcanic eruptions.
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or current flowing to another powered conductor.
Rare-earth element. Refined rare-earth oxides are heavy, gritty powders usually brown or black, but can be lighter colors as shown here. The rare-earth elements ( REE ), also called the rare-earth metals or rare earths or, in context, rare-earth oxides, and sometimes the lanthanides (although scandium and yttrium, which do not belong to this ...
List of chemical elements. 118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z ). [1]
Beta blocker. Skeletal formula of propranolol, the first clinically successful beta blocker. Beta blockers, also spelled β-blockers, are a class of medications that are predominantly used to manage abnormal heart rhythms ( arrhythmia ), and to protect the heart from a second heart attack after a first heart attack ( secondary prevention ).

On 28 November 2016, it was officially named after the Moscow Oblast, in which the JINR is situated. [ 8][ 9][ 10] Moscovium is an extremely radioactive element: its most stable known isotope, moscovium-290, has a half-life of only 0.65 seconds. [ 7] In the periodic table, it is a p-block transactinide element.
