Centrifugal governor - Semantic Scholar

A centrifugal governor is a specific type of governor with a feedback system that controls the speed of an engine by regulating the amount of fuel (or working fluid) admitted, so as to maintain a near-constant speed, irrespective of the load or fuel-supply conditions. It uses the principle of proportional control.

Aug 16, 2021 One hundred forty-seven soil samples were collected from corn fields located within 63 Illinois counties during the 2018 and 2020 corn growing seasons. The soil samples were analyzed for frequency and population density of plant-parasitic nematodes. A total of 10 plant-parasitic nematode taxa were identified. Spiral nematode (Helicotylenchus spp.) was the …

Soil samples of 100 to 500 ml. are washed through a 20-mesh sieve into a 2-gallon bucket. After half filling with water, the mixture is well stirred and then allowed to stand for about 30 sec. before decanting through a 270- or 325-mesh sieve. This is done twice and the residue on the sieve collected in a beaker; the remaining soil is discarded.
