Normal-incidence multilayer mirrors for the 120-450 å wavelength region

An electron-beam deposition method is used to fabricate spherical and flat mirrors with a peak reflectivity of 20% for wavelengths between 120 and 450 ?. It is experimentally shown that the fabricated mirrors can be employed to form an image with a resolution of 1 μm for ultrasoft x rays. The possibility of producing intense directional high-temperature plasma radiation by spherical multilayer mirrors is demonstrated. A radiation intensity of 107 W/cm2 around 182 ? has been experimentally obtained in the laser plasma image plane.     

Hyperbaric oxygenation in the combined treatment of acute kidney failure]

The paper presents the review of the treatment performed in 183 patients with acute renal failure caused by trauma, myorenal syndrome, surgical, obstetric and urological lesions. All the patients underwent hemodialysis. The majority of the patients manifested hypoxia due to pulmonary edema and abnormal central and visceral hemodynamics, anemia resultant from blood loss and suppression of hemopoiesis, impairment of tissue oxidation-reduction enzymes by uremic toxins. Hemodialysis aggravated hypoxia. A direct relationship existed between arterial hypoxemia and the degree of metabolic acidosis, electrolyte alterations and residual diuresis in oligoanuric stage of acute renal failure. The treatment of 48 relevant patients involved 5-10 sessions of hyperbaric oxygenation (1.5-2.2 atm for 60-90 min). The session usually followed hemodialysis. The response was achieved in arterial hypoxemia, central hemodynamics, peripheral blood, water-electrolyte balance, acid-base equilibrium, uremic intoxication. The frequency of hemodynamic reactions during hemodialysis and pyoseptic complications induced by uremia reduced as well as the need in urgent hemodialysis. The introduction of hyperbaric oxygenation diminished the lethality by 29%.     

Injuries to the musculus quadriceps femoris]

The work gives an analysis of results of operative treatment of 63 patients with different injuries of the musculus quadriceps femoris. Problems of diagnostics, surgical strategy and operative technique are discussed depending on the character of injuries (open and closed), their localization and ways of rehabilitation of the patients in the postoperative period.
