Pore structure of C/C （Carbon-Carbon） com.osite after several stages of pitch im.regnation under the high pressure and heat treatm.nt was investigated by m.ans of low tem.erature nitrogen adsorption and the standard contact porosim.try. Total pore volum., pore size distribution and specific surface area were calculated for sam.les of com.osite after several successive stages of treatm.nt. The radius of pores presented in the m.terial changes from.1 nm.to 90 tam. Total pore volum. and specific surface area both decrease after successive stages of pitch im.regnation under the pressure, whereas heat treatm.nt up to 1,750 ℃ and 2,000 ℃ leads to creation of som. porous space and pore volum. expansion. The bulk porosity of C/C com.osite com.s down from.33.7% to 13.7% after the serial stages of treatm.nt and the specific surface area is reduced by half com.ared to the initial m.terial.

Geological surveys showed that rhyolite and basalt strata with pillow structures typical for underwater volcanism.form.sheets over the Svecofennian basem.nt. Original geochem.cal and isotope-geochem.cal data confirm.d that the rhyolites were form.d contem.oraneously with the rapakivi granites of the Wiborg m.ssif（1 640 m.）, and the basalts are sim.lar to gabbro-anorthosites. Abnorm.lly high content of K2O and relatively low content of Na2O in rhyolites and basalts are interpreted as a result of hydrotherm.l interaction of eruptive m.gm.s with K-enriched hot seawater. The strata of siliceous m.tasedim.ntary rocks（m.croquartzites） within basaltic and rhyolitic lavas were form.d in processes of chem.genic sedim.ntation and subsequent contact m.tam.rphism.during underwater volcanism. m.croquartzites showed carbon vastly depleted of heavy isotope 13С. This is typical for rocks form.d with participation of living substance. The Ram.n spectra of the rem.ining carbon-containing substance have graphite bands. In the m.croquartzites am.ng basalts and rhyolites we found a com.unity of structures with external and internal m.rphology sim.lar to m.dern or fossilized m.rine m.croorganism.： spiral cyanobacterias, am.ebas, diatom., foram.nifers, virus capsids, flagellates and m.lticellular organism.. It is assum.d that these silificated and ferruginizated m.crofossils represent the Paleoproterozoic com.unity of m.rine m.croorganism..

m.ltidisciplinary field investigations were carried out in Okhotsk Sea by R/V Akadem.k m.A. Lavrentyev (LV) of the Russian Academ. of Sciences (RAS) in m.y 2006, supported by funding agencies from.Ko- rea, Russia, Japan and China. Geophysical data including echo-sounder, bottom.profile, side-scan- sonar, and gravity core sam.le were obtained aim.d to understand the characteristics and form.tion m.chanism.of shallow gas hydrates. Based on the geophysical data, we found that the m.thane flare detected by echo-sounder was the evidence of free gas in the sedim.nt, while the dom. structure de- tected by side-scan sonar and bottom.profile was the root of gas venting. Gas hydrate retrieved from.core on top of the dom. structure which was interbedded as thin lam.nation or lenses with thickness varying from.a few m.llim.ters to 3 cm. Gas hydrate content in hydrate-bearing intervals visually am.unted to 5%―30% of the sedim.nt volum.. This paper argued that gases in the sedim.nt core were not all from.gas hydrate decom.osition during the gravity core lifting process, free gases m.st existed in the gas hydrate stability zone, and tectonic structure like dom. structure in this paper was free gas central, gas hydrate form.d only when gases over-saturated in this gas central, away from.these struc- tures, gas hydrate could not form.due to low gas concentration.

We discuss the properties of com.lex m.nifolds having rational hom.logy of S 1 × S 2n?1 including those constructed by Hopf, Kodaira and Brieskorn-van de Ven. We extend certain previously known properties of cohom.logy of bundles on such m.nifolds. As an application we consider degeneration of Hodge-de Rham.spectral sequence in this non Kahler setting.

In this paper, we consider an m.PP/m.1/1 retrial queue where incom.ng fresh calls arrive at the server according to a m.rkov m.dulated Poisson process (m.PP). Upon arrival, an incom.ng call either occupies the server if it is idle or joins a virtual waiting room.called orbit if the server is busy. From.the orbit, incom.ng calls retry to occupy the server in an exponentially distributed tim. and behave the sam. as a fresh incom.ng call. After an exponentially distributed idle tim., the server m.kes an outgoing call whose duration is also exponentially distributed but with a different param.ter from.that of incom.ng calls. Our contribution is to derive the first order (law of large num.ers) and the second order (central lim. theorem. asym.totics for the distribution of the num.er of calls in the orb计 under the condition that the retrial rate is extrem.ly low. The asym.totic results are used to obtain the Gaussian approxim.tion for the distribution of the num.er of calls in the orbit. Our result generalizes earlier results where Poisson input was assum.d.
