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 ...
Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
Coffee is a beverage brewed from roasted, ground coffee beans.Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content.
While a rising birth rate is contributing to population growth, it remains considerably below the baby boom peak of 2.95 children per woman in 1964, [351] or the high of 6.02 children born per woman in 1815, [352] below the replacement rate of 2.1, but higher than the 2001 record low of 1.63. [353]
Violent crime rates vary significantly by area of the city, with more economically developed areas having low rates, but other sections have much higher rates of crime. [302] In 2013, the violent crime rate was 910 per 100,000 people; [ 304 ] the murder rate was 10.4 per 100,000 – while high crime districts saw 38.9 murders, low crime ...
Here, h signifies low-latitude climates (average annual temperature above 18 °C (64.4 °F)) while k signifies middle-latitude climates (average annual temperature less than 18 °C). In addition, n is used to denote a climate characterized by frequent fog and H for high altitudes.
During the first four years of Chávez's presidency, the economy initially grew between 1999 and 2001 but contracted from 2001 to 2003, returning to GDP levels similar to those of 1997. The early decline was influenced by low oil prices and later exacerbated by the events surrounding the 2002 coup attempt and the 2002–2003 general strike.
The number π (/ p aɪ /; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.
