V̇O 2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. [1] [2] The name is derived from three abbreviations: "V̇" for volume (the dot over the V indicates "per unit of time" in Newton's notation), "O 2" for oxygen, and "max" for maximum and usually normalized per kilogram of ...
Productivity-improving technologies date back to antiquity, with rather slow progress until the late Middle Ages. Important examples of early to medieval European technology include the water wheel, the horse collar, the spinning wheel, the three-field system (after 1500 the four-field system—see crop rotation) and the blast furnace.
The presence of the thin oxide layer on a silicon-sphere mass prototype places additional restrictions on the procedures that might be suitable to clean it to avoid changing the layer's thickness or oxide stoichiometry. All silicon-based approaches would fix the Avogadro constant but vary in the details of the definition of the kilogram.
Conversely, the general consensus is that early action to reduce emissions would help avoid much greater economic costs later, and reduce the risk of catastrophic, irreversible change. [ 102 ] Earlier, climate change deniers' online YouTube content focused on denying global warming, or saying such warming is not caused by humans burning fossil ...
The economy of Japan is a highly developed mixed economy, often referred to as an East Asian model. [24] It is the fourth-largest economy in the world by nominal GDP behind the United States, China, and Germany, and the fifth-largest by purchasing power parity (PPP), below India and Russia but ahead of Germany.

Gregory's calendar reform modified the Julian rule, to reduce the average length of the calendar year from 365.25 days to 365.2425 days and thus corrected the Julian calendar's drift against the solar year: the Gregorian calendar gains just 0.1 day over 400 years. For any given event during the years from 1901 through 2099, its date according ...
Notably, a similar fraction of global crop and livestock production would also experience a large change in HLZ, but in more developed areas which would have better chances of adapting. In contrast, under the low-emissions SSP1-2.6, 5% and 8% of crop and livestock production would leave what is defined as the safe climatic space. [16]
The ideology behind the term, originally used for the less publicized attempts at assimilation of the Pomaks in the early 1970s, was the claim that the targeted minority had originally been Bulgarian before its conversion or assimilation during the period of Ottoman rule. Thus, the assimilation was supposedly justified by it being a restoration ...
