Abstract Using the second law of local thermodynamics and the first-order Palatini formalism, we formulate relativistic spin hydrodynamics for quantum field theories with Dirac fermions, such as QED and QCD, in a torsionful curved background.We work in a regime where samsung a71 price toronto spin density, which is assumed to relax much slower than

This paper analyzes the interactions between typhoons (TYs) Parma and Melor (2009) in the North West Pacific (NWP) Ocean.The TY Parma (2009) is chosen for investigation because it has a unique track with multiple U-turns and 3 landfalls over the Luzan Island of Philippines that are extremely difficult, if not impossible, to forecast by numerical we

In the last half of the 2010s, we saw an upswing in antiscience movements and unprecedented attacks on scientists in the United States and elsewhere.All indications suggest that this trend will not slow or reverse anytime soon, and it 15lb nitrous bottle is now increasingly apparent that it will fall to the scientists themselves to respond, engage
