The mean corpuscular hemoglobin concentration (MCHC) is a measure of the concentration of hemoglobin in a given volume of packed red blood cell. It is calculated by dividing the hemoglobin by the hematocrit. Reference ranges for blood tests are 32 to 36 g/dL (320 to 360g/L), [1] or between 4.81 and 5.58 mmol/L. It is thus a mass or molar ...
Polycythemia is defined as serum hematocrit (Hct) or hemoglobin (HgB) exceeding normal ranges expected for age and sex, typically Hct >49% in healthy adult men and >48% in women, or HgB >16.5 g/dL in men or >16.0 g/dL in women. [8]
Mecca has been referred to by many names. As with many Arabic words, its etymology is obscure. [24] Widely believed to be a synonym for Makkah, it is said to be more specifically the early name for the valley located therein, while Muslim scholars generally use it to refer to the sacred area of the city that immediately surrounds and includes the Ka'bah.
Winters are cold, with 22 days where the high temperature is at or below 32 °F (0 °C) and 2.5 nights with a low at or below 0 °F (−18 °C). [51] The official record highest temperature is 113 °F (45 °C), set on August 14, 1936, at Downtown Airport, while the official record lowest is −23 °F (−31 °C), set on December 22 and 23, 1989 ...
Frost usually occurs in the early winter mornings, and there is a slight wind chill in the city at elevated areas that causes the cold mornings to be bitter, including low humidity. The sun warms the city to the high 20–22 °C (68–72 °F) during the noontime but it drops drastically after nightfall to a low around 3–4 °C (37–39 °F).
The mean age at childbearing indicates the age of a woman at their childbearing events, if women were subject throughout their lives to the age-specific fertility rates observed in that given year. [1] In countries with very high fertility rates women can have their first child at a much younger age than the mean age at childbearing.
A 2022 study in PNAS found that earnings inequality in the United States did not increase over the preceding decade, marking the first reversal of rising earnings inequality since 1980. The reversal was due to a shrinking wage gap between low-wage workers and median-wage earners, which was due to broadly rising pay in low-wage professions.
A standard wire gauge. American Wire Gauge (AWG) is a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire.
