This study investigates the last two centuries sedimentation dynamics in four high-altitude lakes located in Southern Carpathians, Romania. Furthermore, a novel approach is proposed for identifying the anthropic or natural ...
Cím: Symmetry Breaking and Dynamic Transition in the Negative Mass Term Klein–Gordon Equations
Szerző: ;
Dátum: 2024
Feltöltve: 2024-02-08
(2024)
Through the discussion of three physical processes, we show that the Klein–Gordon equations with a negative mass term describe special dynamics. In the case of two classical disciplines—mechanics and thermodynamics—the ...
Cím: Comparison of plant biostimulating properties of Chlorella sorokiniana biomass produced in batch and semi-continuous systems supplemented with pig manure or acetate
