The density of quartz is around 2.65 g/cm 3 but the dry bulk density of a soil can be less than half that value. Most soils have a dry bulk density between 1.0 and 1.6 g/cm 3 but organic soil and some porous clays may have a dry bulk density well below 1 g/cm 3.
After an introduction, possibly explaining how to identify the first nagu, the next seven nagu are each introduced by the clause "To the n-th region [nagu], where you travel 7 leagues" (the distance of 7 leagues seems to indicate the width of the Ocean, rather than the distance between subsequent nagu).

[3] The novel Daantjie Dreamer (1993) is about a family from the 1950s. The narrator is the daughter Bubbles, who wants to free herself from the environment in which she grew up. Through her conversations with her philosophically inclined brother Daantjie Dreamer, she comes to new insights about political matters and she is aware of her own ...
Clay cannot be resolved by optical microscopes as its particles are 0.002 mm (7.9 × 10 −5 in) or less in diameter and a thickness of only 10 angstroms (10 −10 m). [ 16 ] [ 17 ] In medium-textured soils, clay is often washed downward through the soil profile (a process called eluviation ) and accumulates in the subsoil (a process called ...
Daniel Charl Stephanus Oosthuizen (also known as Daantjie Oosthuizen; 15 January 1926 – 4 April 1969) was a South African philosopher, and an early Afrikaner voice against Apartheid. The main direction of his philosophical work lay in the field of epistemology and the philosophy of mind.
Other units include the schoenus (from the Greek for "rush rope") used for the distances in Isidore of Charax's Parthian Stations (where it had a value around 5 km or 3 miles) [8] [9] and in the name of the Nubian land of Triacontaschoenus between the First and Second Cataracts on the Nile (where it had a value closer to 10.5 km or 6 + 1 ⁄ 2 ...
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
The Hausdorff distance is the longest distance someone can be forced to travel by an adversary who chooses a point in one of the two sets, from where they then must travel to the other set. In other words, it is the greatest of all the distances from a point in one set to the closest point in the other set.
