Deflocculation is the opposite of flocculation, sometimes known as peptization. Sodium silicate (Na 2 SiO 3) is a typical example. Usually, in higher pH ranges, in addition to low ionic strength of solutions and domination of monovalent metal cations, the colloidal particles can be dispersed. [21]
Since absolute aggregation rates are difficult to measure, one often refers to the dimensionless stability ratio W, defined as = where k fast is the aggregation rate coefficient in the fast regime, and k the coefficient at the conditions of interest. The stability ratio is close to unity in the fast regime, increases in the slow regime, and ...
Negative utilitarianism is a form of negative consequentialism that can be described as the view that people should minimize the total amount of aggregate suffering, or that they should minimize suffering and then, secondarily, maximize the total amount of happiness.
In the above formulation, the paradox is that the two procedures do not necessarily lead to the same result; the two procedures can even lead to opposite results. Pettit believes that the lesson of this paradox is that there is no simple way to aggregate individual opinions into a single, coherent "group entity".
In biology, hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. Hemostasis involves three major steps: vasoconstriction; temporary blockage of a hole in a damaged blood vessel by a platelet plug
If you're interested in maintaining your hormonal levels, you might wonder if there are certain foods that kill testosterone. After all, testosterone naturally decreases with age, so it's ...
This duplicate derivation went unnoticed for years because the two scientific papers were published on opposite sides of the Iron Curtain in 1961. [ citation needed ] It was not until 1975 that Kahlweit addressed the fact that the theories were identical [ 11 ] and combined them into the Lifshitz-Slyozov-Wagner or LSW theory of Ostwald ripening.
