[Cases of pyogenic iliopsoas abscesses in military men].

Four cases of pyogenic inflammation of the iliolumbar muscle were analyzed and 3 clinical cases of this disease in military men are described. A rare case of abscess of the iliolumbar muscle complicated by secondary appendicitis is also described. A hematogenic way of infection against the background of microtraumas and hematomas with m.

Study of temperature effect on far-infrared spectra of liquid H2O and D2O by analytical theory and molecular dynamic simulations.

The results of a combined study of dielectric loss (epsilon"(nu)) and power-absorption coefficient (alpha(nu)) are reported. The epsilon"(nu) and alpha(nu) values are obtained for liquid water (H2O) and heavy water (D2O) using analytical modeling and the molecular dynamics (MD) simulations method. The calculated spectra span the microwave and far-infrared (FIR) region.

Basic molecular mechanisms underlying complex permittivity of water and ice.

Four dielectric-loss frequency dependences epsilon''j(nu), j = 1-4, which constitute a basis for underlying far-infrared (FIR) spectra of water and ice, are briefly analyzed. The relevant molecular mechanisms are (a) free-like libration of a permanent dipole in a hat potential, (b) elastic vibration of a nonrigid dipole along the H-bond (HB), (c) elastic reorientation of a permanent dipole around this bond, and (d) vibration of HB water molecules transverse to the HB direction. A semiphenomenological (SP) approach, based on analytical calculation of the spectrum of autocorrelation function, is applied.
