Warframe / Game Breaker - TV Tropes
The base Nukor's gimmick is that it has an amazing base status chance, while having one of the lowest critical chances in the game at only 3%— but has a 4x critical damage multiplier. The Kuva Nukor has a still not-great 7% critical chance, but also has a 5x critical multiplier, which can go up to 10.5x before Rivens.

Stoichiometric ratios of the starting materials were mixed and milled for 96 h by a mechanical ball milling (SPEX 8000D with speed of 875 rpm). In this step, we used stainless- steel balls and vial. The starting materials were put in a vial (vo- lume 65 cm3), here the weighted ratio between balls and sample was about 8:1.

About the same time Captain Towers built his mill, Mr. Silas Levering erected his hotel-the first hotel in Manayunk; and the captain built a small house, in which he resided, on the lower side of the canal adjoining his mill. When he had completed his mill he rented the third story to Isaac Baird, who was the first cottonspinner of Manayunk.

Speed-Flow-Density Relationship - University of Idaho
Under uninterrupted flow conditions, speed, density, and flow are all related by the following equation: q = k*v. Where. q = Flow (vehicles/hour) v = Speed (miles/hour, kilometers/hour) k = Density (vehicles/mile, vehicles/kilometer) Because flow is the product of speed and density, the flow is equal to zero when one or both of these terms is zero.
