Recent experiments on particle diffusion in bacterial baths indicate the formation of correlated structures in the form of bacterial swirls. Here we predict that such a structural ordering would give rise to the new effect of propagating shear waves in a bacterial bath at length scales of the order of a swirl, which corresponds to time scales of the order of the lifetime of a swirl. Our predict...

A 10% random sample of all bathers at a public swimming bath were examined for tinea pedis and verruca.The overall incidence of tinea pedis was 8.5% and of verruca 4.8%. The incidence of tinea pedis in 205 male adults was 21.5%, in 288 boys 6.3%, in 60 adult females 3.3%, and in 220 girls 0.9%. The incidence of verruca in juveniles ranged from 4.2% in boys to 10.5% in girls.It was clear that bo...

We study a XY model which consists of a spin chain coupled to heat baths. We give a repeated quantum interaction Hamiltonian describing this model. We compute the explicit form of the associated Lindblad generator in the case of the spin chain coupled to one, two and several heat baths. We further study the properties of quantum master equation such as approach to equilibrium, local equilibrium...

Purpose Hot peat baths (40 45 °C) are used in rehabilitation medicine to treat pain, increase perfusion and relax muscles. Because of substantial heat stress (core body temperature increased by 1 1.5 °C within 30 min) patients ́ linear HRV parameters are influenced due to sympathovagal activity. The aim of the observational study was to investigate reactions of the cardiac autonomic nervous syst...

The Carnot theorem, one expression of the second law thermodynamics, places a fundamental upper bound on efficiency heat engines operating between two baths. theorem can be stated in more generalized form for with multiple baths, where maximum is achieved reversible quasistatically In this study, we determine irreversible baths linear response regime, i.e., under small temperature differences a...

The physical treatment most frequently used for the hands in rheumatoid arthritis is the local paraffinwax bath. It was first described by Humphris (1919) and since then has been in general use. The standard textbooks of physical medicine and rheumatology refer to wax baths as being of value, but we have been unable to find any critical attempt to assess this. It is unusual for a patient with r...

We numerically study the hyperfine induced nuclear spin dynamics in a system of two coupled quantum dots in zero magnetic field. Each of the electron spins is considered to interact with an individual bath of nuclear spins via homogeneous coupling constants (all coupling coefficients being equal). In order to lower the dimension of the problem, the two baths are approximated by two single long ...
