Experimental evidence of strong phonon scattering in isotopical disordered systems: The case of LiH_xD_{1-x} crystals

The observation of the local - mode vibration, the two - mode behavior of the LO phonons at large isotope concentration, as well as large line broadening in LIH - D mixed crystals directly evidence strong additional phonon scattering due to the isotope - induced disorder.Comment: 9 pages, 4 figure

Clinical-microbiological characteristics of stationary urinary tract infections in capable people in conditions of north

Urgency of the research was determined by insufficiency of information in modern literature about microbiological structure antibiotic sensitivity of main pathogens of urinary tract infection among capable people in conditions of hospital. The aim. of the research was to increase effectiveness of antibiotic therapy of stationary infections of urinary tract in conditions of north. The results of stationary examination of 1109 capable patients (males and. females) with infections of urinary tract from 1998 to 2009 years were studied. Data of microbiological examination is based on 700 bacteriological urine analyses. Antibiotic sensitivity of uropathogens was determined by disc-diffuse method. Structure of stationary infections of urinary tract in groups of patients of one sex was quite equal, but at the same time there are significant differences between groups of males and. females. Lately infections of urinary tract caused by intrahospital pathogens that are non-sensitive to common antibiotics (Proteus, KIebsieIIa and. Pseudomonas родов) started to be revealed, in patients arriving from other hospitals. It demands using reserve antibiotics. This underscores urgency of monitoring of uropathogens spectrum, and. their antibiotic-sensitivity for each hospital that has respective possibiIities. It was reveaIed. that chronic pyelonephritis with concomitant urolithiasis is the main nosoform in capable peopIe in conditions of north, in the structure of stationary infections of urinary tract. Acute and uncomplicated chronic pyeIonephritis and. aIso acute and. chronic cystitis more than twice prevaiI among femaIes in comparison, with males. The most important pathogens of stationary infections of urinary tract are: S. epidermidis, S. saprophyticus S. aureus for men; E. coIi, S. еpidermidis S. saprophyticus and. S. aureus for women at uncompIicated infections of urinary tract and. E. coli, S. saprophyticus, S. epidermidis for women at compIicated infections of urinary tract. Main uropathogens in researched, contingent had. higher sensitivity in vitro for gentamycin ofIoxacin, and Iower sensitivity — for cefotaxime, ceftriaxone and. ciprofloxacin. The most of resistant cuItures for antibacterial preparations that are the most frequently used for the treatment of infections of urinary tract is among E. coli, the Ieast part — among S. aureus

Modern approaches to complex therapy of chronic nonspecific endometritis (review of literature)

The article presents the review of modern Russian and foreign literature devoted to a problem of treatment of chronic endometritis. It was shown that treatment of this pathology should be conducted in two stages. The basis of the first stage is antibacterial therapy, the basis of the second stage is complex treatment with application of vascular preparations, vitamin therapy, endocrinotherapy, physiotherapy. In addition the article brings up several debatable questions of treatment of chronic endometritis and expediency of application of hormones, probiotic, immunomodulators in particular. Also the article presents the estimation of various methods of medical products introduction. The positive effect is received from local application of medical products. It was noticed that the search of new medical products is proceeding
