The influence of continious CO2-laser processing on structure, composition and microhadness of plasma sprayed Ni-Cr-Si-B, Fe-C-Cr-V, Ni-Al coatings was studied. The change of chemical and phase compositions of the coatings compared with the initial sprayed ones due to alloying with elements of substrate, depending on the processing operation (input power) was determined. Laser processing of plasma sprayed coatings allows to improve substantially their adhesion and in combination with high speed cooling, gives the possibility to regulate the processes of structure formation, dispersion, phase formation, and hence, the properties of forming coatings by means of processing operation.

Небольшое, распространенное в Старом Свете, семейство Leptopodidae, по данным Schuh et al. (1987) в фауне Индии представлено тремя видами рода Leptopus Latreille 1809 (L. travancorensis Distant 1910, L. decus Drake 1954 и L. scutulus Drake 1955) и одним видом рода Valleriola Distant 1904 (V. cicindeloides Distant 1909). В статье описывается новый вид Leptopus, собранный арахнологом Ю.М. Марусиком в Гималаях. Типовой материал хранится в коллекции Зоологического института РАН, С.-Петербург.

By using data treatment results of mid-latitude geomagnetic variations, the significant increase of the local current system intensity with the eastern direction current system, arising near the meridian of expected substorm center ~10-30 min before the break-up onset, has been found. A comparison of longitudinal sizes of two current system, forming the substorm disturbance before and after the onset of the substorm expansion phase, has been carried out. The longitudinal size of the current loop of the substorm growth phase is nearly twice as small as azimuth scale of the substorm current wedge, and the current strength is as week as 2.7-12 times.

Analysis of the global magnetosphere-ionosphere response to solar wind dynamic pressure variations under the negative IMF Bz has been performed. It is shown that an increase in the dynamic pressure leads to a double response of the ionospheric currents and aurora, i.e. simultaneously (within the accuracy of 1 min) and ~5-7 min afterward. Thereby, the eastward and westward convective electrojets are enhanced in the evening and morning sectors respectively, followed by the intensification of the westward current in the near midnight and evening sectors. The intensification of the electrojets is followed by extension of the diffuse precipitation zone and its high latitude boundary movement to the pole and to the east in the midnight-to-morning sector. In our case, no poleward or westward extension of aurora before midnight is observed. The disturbance triggered by a dynamic pressure increase may be considered as a convection disturbance associated with reconstruction of the DP2 current system.

Large-amplitude morning Pc5 magnetic pulsations during the main phase of intense magnetic storm were registered at magnetic stations of 190-200° magnetic meridians on January 21-22, 2005. Magnetic pulsations in the Pc5 frequency range observed at the GOES 10, 12 satellites in the noon and evening sectors exhibited a high degree of magnetic compessibility. A Los Alamos particle detector on board geostationary satellite observed the occurrence of energetic particle flux oscillations in the Pc5 band. The Pc5 pulsations were followed with the VLF-emission and riometer absorption modulation with the same period. The regions of maximal amplitude of Pc5 geomagnetic pulsations and deep modulation of riometer absorptions shifted to high latitudes in the same way. Significant and long-lasting compression of magnetosphere led, probably, to moderate pitch-angle diffusion of particle into the loss cone even at the middle latitudes. Analysis of coordinated data allowed us to suggest that a modulation effects of precipitating particles are caused by a compressional waves.
