    Herbarium collections of the genus Camelina preserved at the Institute of General and Experimental Biology of the Academy of Sciences of Mongolia (UBA) and the Komarov Botanical Institute of the Russian Academy of Sciences (LE) were studied. The collections of these Herbaria contain materials of 3 species from Mongolia (C. caucasica (Sinsk.) Vass., C. sativa (L.) Crantz, C. sylvestris Wallr.) and 4 from China (C. sativa, C. linicola Schimp. et Spenn., C. microcarpa Andrz., C. sylvestris)

    Objective: to study perioperative humoral immunity (IgA, IgM, IgG, and CD19+) during nutritive maintenance in patients with acute destructive calculous cholecystitis.Subjects and methods. The study was based on the results of studying probe nutritive maintenance in patients with acute destructive calculous cholecystitis intraoperatively and on days 1—3 after cholecystectomy. In the study group, nutritive maintenance using a polymer balanced lactose-free dry Berlamine-Modular formula (Berlin-Chemie, Germany) was made in 34 patients. A control group comprised 29 patients. An option of intermittent administration of the feeding formula was chosen for nutritive maintenance.Results. Perioperative nutritive maintenance in patients with acute destructive calculous cholecystitis improved humoral immunological parameters and reduced the incidence of postoperative and pyoinflammatory complications and the length of hospital stay. Цель исследования — изучить гуморальный иммунитет (IgA, IgM, IgG, CD19+) в периоперационном периоде на фоне нутриционной поддержки у больных с острым деструктивным калькулезным холециститом.Материалы и методы. В основу работы положены результаты изучения зондовой нутриционной поддержки у больных с острым деструктивным калькулезным холециститом интраоперационно в 1—3-и сутки после холецистэктомии. Нутриционную поддержку проводили в основной группе полимерной сбалансированной безлактозной сухой смесью Берламин-Модуляр (Berlin-Chemie, Германия) 34 больным. Контрольную группу составили 29 больных. Для нутриционной поддержки был выбран метод дробного введения питательной смеси.Результаты. Применение нутриционной поддержки в пе-риоперационном периоде у больных с острым деструктивным калькулезным холециститом позволило улучшить показатели гуморального иммунитета, снизить частоту послеоперационных и гнойно-воспалительных осложнений и уменьшить длительность пребывания больного в стационаре.

    Magnetic phase diagram and transport properties of FeGe_2

    We have used resistivity measurements to study the magnetic phase diagram of the itinerant antiferromagnet FeGe_2 in the temperature range from 0.3->300 K in magnetic fields up to 16 T. In contrast to theoretical predictions, the incommensurate spin density wave phase is found to be stable at least up to 16 T, with an estimated critical field \mu _0H_c of ~ 30 T. We have also studied the low temperature magnetoresistance in the [100], [110], and [001] directions. The transverse magnetoresistance is well described by a power law for magnetic fields above 1 T with no saturation observed at high fields. We discuss our results in terms of the magnetic structure and the calculated electronic bandstructure of FeGe_2. We have also observed, for the first time in this compound, Shubnikov-de Haas oscillations in the transverse magnetoresistance with a frequency of 190 +- 10 T for a magnetic field along [001].Comment: 13 pages, RevTeX, 7 postscript figures, to appear in Journal of Physics: Condensed Matte

    Dissipative Van der Waals interaction between a small particle and a metal surface

    Full text link
    We use a general theory of the fluctuating electromagnetic field to calculate the friction force acting on a small neutral particle, e.g., a physisorbed molecule, or a nanoscale object with arbitrary dispersive and absorptive dielectric properties, moving near a metal surface. We consider the dependence of the electromagnetic friction on the temperature TT, the separation dd, and discuss the role of screening, non-local and retardation effects. We find that for high resistivity materials, the dissipative van der Waals interaction can be an important mechanism of vibrational energy relaxation of physisorbed molecules, and friction for microscopic solids. Several controversial topics related to electromagnetic dissipative shear stress is considered. The problem of local heating of the surface by an STM tip is also briefly commented on.Comment: 11 pages, No figure
