The article discusses the dependences of carbon monoxide (II) grandpas best concentrations on the height of the building façade based on the results of in situ tests with the goal of preventing the inflow of pollutants into the ventilation system.Carbon oxide (II) may enter the premises when the inlet ventilation system is working through the inle
A numerical method for the prediction of noise of the internal vegas golden knights background combustion engine exhaust system is presented in the paper.The engine has been modelled by the system of nonlinear differential equations while the exhaust system has been modelled by linear differential equations.The correlation between the engine mathem
Measurements of rotational lines emitted by middle atmospheric trace gases have been carried out from the Alpine station of Testa Grigia (45.9°N, 7.7°E, elev.3500 m) by means of a Ground-Based Millimeter-wave Spectrometer (GBMS).Observations of species such as O3, HNO3, CO, N2O, HCN, and HDO took place during 4 winter periods, from
Gene duplication generates extra gene copies in which mutations can accumulate without risking the function of pre-existing genes.Such mutations modify duplicates and contribute to evolutionary novelties.However, the vast majority of duplicates appear to be short-lived and experience duplicate silencing within a few million years.Little is known ab
