The Alfvenic cascade(AC ) mode is a branch of sheared Alfvenic modes localized at the magnetic surface with minimum safety factor(q ).Usually,a strong gradient region so-called internal transport barrier(ITB ) appears around the minimum q surface[1].The effect of pressure gradient on AC modes has been investigated by different authors,but their conclusions are contradictory to each other[2.3..In this

AT present, the main source of germanium includes two types of ore deposits: some sulfide-rich Pb, Zn,Cu, Ag and An deposits and some coal deposits. Germanium occurs as an associated element in these oredeposits. The Lincang germanium deposit discovered recently in china occurs in a basin where there areexposed the Neogene coal-bearing clastic rocks with Indosinian Ge-rich (（1.9-5.0）×10-6) granitesas the basement in Lincang County, Yunnan Province. Germanium is mainly concentrated in the coalseams of the first coal-bearing horizon (Nth2./sup>) and in regard to its grade (normally n×100×10-6 with themaximum over 1000×10-6) and scale （the proven reserve about 800 t）, no such germanium mineralization has been reported so far in other parts of the world. What is the reason? The available studies have indicated that this germanium deposit is of epigenetic origin, whichdetermines that germanium must have been transferred into coal with the help of a kind of medium. It isnoticed that （i） organic germanium in natural waters is stable and it is never involved in its

The changes of microbial biomass carbon (MBC) and nitrogen (MBN) and microbial community in the topsoil of the abandoned agricultural land on the semi-arid Loess Plateau in china during the natural succession were evaluated to understand the relationship between microbial community and soil properties. MBC and MBN were measured using fumigation extraction, and microbial community was analyzed by the method of fatty acid methyl ester (FAME). The contents of organic C, total N, MBC, MBN, total FAME, fungal FAME, bacterial FAME and Gram-negative bacterial FAME at the natural succession sites were higher than those of the agricultural land, but lower than those of the natural vegetation sites. The MBC, MBN and total FAME were closely correlated with organic C and total N. Furthermore, organic C and total N were found to be positively correlated with fungal FAME, bacterial FAME, fungal/bacterial and Gram-negative bacterial FAME. Natural succession would be useful for improving soil microbial properties and might be an important alternative for sustaining soil quality on the semi-arid Loess Plateau in china.

A new chlorine-containing neo-clerodane diterpene, teupernin D, was isolated from the aerial parts of Teucrium pernyi. The structure for teupernin D was established as (12.) -15, 16-epoxy-8β-hydroxy-17-chloro-19-nor10α-neo-cleroda-4, 13.16), 14-triene-18,6β;2.,12.diolide on the basis of spectral evidence. The absolute configuration was established by CD spectrum and confirmed by X-ray crystallographic analysis.

In this article, we study the rate of convergence of the polygonal approximation to multiple stochastic integral Sp （f） of fractional Brownian motion of Hurst parameter H 〈 1/2.when the fractional Brownian motion is replaced by its polygonal approximation. Under different conditions on f and for different p, we obtain different rates.

We reported in this manuscript that TGF-β1 induces apoptosis in AML12.murine hepatocytes, which is associated with the activation of p3. MAPK signaling pathway. SB2.2.90, a specific inhibitor of p3. MAPK, strongly inhibited the TGF-β1-induced apoptosis and PAI-1 promoter activity. Treatment of cells with TGF-β1 activates p3.. Furthermore, over-expression of dominant negative mutant p3. also reduced the TGF-β1-induced apoptosis. The data indicate that the activation of p3. is involved in TGF-β1-mediated gene expression and apoptosis.
