The improvement in technology of rectification column calculation
IOP Conference Series: Earth and Environmental Science, 2020 Abstract The task of automation and increasing the efficiency of calculating the parameters of the rectifying column for the needs of chemical production is being solved. Rectification is one of the most time-consuming chemical-technological processes responsible for the separation of liquid mixtures into practically pure components ...

Gas isotope thermometry in the South Pole and Dome Fuji ice cores provides evidence for seasonal rectification of ice core gas records [PDF]
The Cryosphere, 2022 Gas isotope thermometry using the isotopes of molecular nitrogen and argon has been used extensively to reconstruct past surface temperature change from Greenland ice cores. The gas isotope ratios δ15N and δ40Ar in the ice core are each set by the amount

Analysis of the Dynamic Characteristics of the Distillation Column of Plate Type
EAI Endorsed Transactions on Energy Web, 2017 The relevance of the study related to the necessity to convert to “unmanned” production in a refinery and, as a consequence, we must derive a mathematical model of the high-octane gasoline process.

Population-scale organization of cerebellar granule neuron signaling during a visuomotor behavior. [PDF]
, 2017 Granule cells at the input layer of the cerebellum comprise over half the neurons in the human brain and are thought to be critical for learning. However, little is known about granule neuron signaling at the population scale during behavior.

Model $I$--$V$ curves and figures of merit of underdamped deterministic Josephson ratchets
, 2016 We propose simple models for the current-voltage characteristics of typical Josephson ratchets. We consider the case of a ratchet working against a constant applied counter force and derive analytical expressions for the key characteristics of such a ...
