Transverse spin dynamics in a spin-polarized Fermi liquid
The linear equations for transverse spin dynamics in weakly polarised
degenerate Fermi liquid with arbitrary relationship between temperature and
polarization are derived from Landau-Silin phenomenological kinetic equation
with general form of two-particle collision integral. The temperature and
polarization dependence of the spin current relaxation time is established. It
is found in particular that at finite polarization transverse spin wave damping
has a finite value at T=0. The analogy between temperature dependences of spin
waves attenuation and ultrasound absorption in degenerate Fermi liquid at
arbitrary temperature is presented. We also discuss spin-polarized Fermi liquid
in the general context of the Fermi-liquid theory and compare it with "Fermi
liquid" with spontaneous magnetization.Comment: 10 page
Electromagnetic waves in an axion-active relativistic plasma non-minimally coupled to gravity
We consider cosmological applications of a new self-consistent system of
equations, accounting for a nonminimal coupling of the gravitational,
electromagnetic and pseudoscalar (axion) fields in a relativistic plasma. We
focus on dispersion relations for electromagnetic perturbations in an initially
isotropic ultrarelativistic plasma coupled to the gravitational and axion
fields in the framework of isotropic homogeneous cosmological model of the de
Sitter type. We classify the longitudinal and transversal electromagnetic modes
in an axionically active plasma and distinguish between waves (damping,
instable or running), and nonharmonic perturbations (damping or instable). We
show that for the special choice of the guiding model parameters the
transversal electromagnetic waves in the axionically active plasma,
nonminimally coupled to gravity, can propagate with the phase velocity less
than speed of light in vacuum, thus displaying a possibility for a new type of
resonant particle-wave interactions.Comment: 19 pages, 9 figures, published versio

The relationship between disorders of iron metabolism and alopecia, in particular telogen hair loss (THL), remains poorly understood and requires further research.
Goal. To assess changes in the dynamics of growth and hair condition in women with an iron deficiency state during systemic therapy with iron supplements in combination with and without physiotherapy.
Methods. An open-label, randomized, comparative interventional study with a duration of 6 months included 26 female aged 19 to 54 years (38.8 8.9 years) with complaints of hair loss, changes in their structure, dryness and / or hair brittleness; with preserved menstrual cycle and mild iron deficiency anemia (IDA, Hb 101120 g/l). Trichoscopy and phototrichogram were performed with processing of the results in the TrichoScienceProv1.1 program. The changes in the dynamics of hair growth and condition were assessed against the background of the use of iron supplements in combination with physiotherapy and without physiotherapy. Pulsed alternating sinusoidal current of high frequency, high voltage and low strength was chosen as a physiotherapeutic method for the treatment of THL.
Results. Against the background of the therapy, an increase in the Hb level (p 0.001) and a positive dynamics of trichological parameters in all patients were noted, the severity of which was higher when the therapy with iron supplements was combined with physiotherapy.
Conclusion. Our findings confirm that the complex treatment of patients with telogen alopecia on the background of an iron deficiency state may achieve positive dynamics of trichological indicators.ΠΠ·Π°ΠΈΠΌΠΎΡΠ²ΡΠ·Ρ Π½Π°ΡΡΡΠ΅Π½ΠΈΡ ΠΎΠ±ΠΌΠ΅Π½Π° ΠΆΠ΅Π»Π΅Π·Π° ΠΈ Π°Π»ΠΎΠΏΠ΅ΡΠΈΠΈ, Π² ΡΠ°ΡΡΠ½ΠΎΡΡΠΈ ΡΠ΅Π»ΠΎΠ³Π΅Π½ΠΎΠ²ΠΎΠ³ΠΎ Π²ΡΠΏΠ°Π΄Π΅Π½ΠΈΡ Π²ΠΎΠ»ΠΎΡ (Π’ΠΠ), ΡΠΎΡ
