Theoretical calculations have been carried out to investigate the possible dissociation channels of isoprene. We focus on the major fragment ions of c5H7＋, c5H5＋, c4H5＋, c3H6＋, c3H5＋, c3H4＋, c3H3＋ and c2H3＋, which were observed experimentally from the isoprene dissociative photoionization. The energy.c.lculations were performed with the cBS-QB3 model. All the geometries and energies of the fragments, intermediates and transition states involved in the dissociations channels were determined. Finally, the mechanisms of the dissociation pathways were discussed on the comparison of theoretical and experimental results.

The studies of uplift and glaciations of the Tibetan Plateau are summarized, and a series of recent case studies of the endemic species based on DNA sequences are detailed. In general, these molecular data show that all the organisms originated from Early Pliocene to Late Miocene, and then multi-stages of divergence/speciation occurred within each taxa following their original occupation on the plateau, mainly as a result of periodic glacial cycles and geographic isolation. The regional fauna may have undergone several range contractions and expansions during the Pleistocene glaciations. However, the population expansion and refugia may vary in space, time, and extent. The regional fauna of the Tibetan Plateau may be combinations of ancient movement from adjacent zoogeographical regions, speciation in situ, and postglacial colonization from adjacent areas. Geomorphic and climatic changes on the plateau definitely have a remarkable influence on the regional and adjacent biogeographic patterns, and the mechanism is very.c.mplex.

We have investigated the photoinduced decomposition of formaldehyde （cH2O） on a rutile TiO2（100）-（1×1） surface at 355 nrn using ternperature-prograrnrned desorption. Products, formate （HcOO）, methyl radical （cH3.）, ethylene （c2H4）, and methanol （cH3OH） have been detected. The initial step in the decomposition of cH2O on the futile TiO2（100）-（1×1） surface is the formation of a dioxyrnethylene intermediate in which the carbonyl O atom of cH2O is bound to a Ti atom at the five-fold-coordinated Ti4＋（Tisc） site and its carbonyl c atom bound to a nearby bridge-bonded oxygen （Oh） atom, respectively. During 355 nrn irradiation, the dioxymethylene intermediate can transfer an H atom to the Ob atom, thus forming HcOO directly, which is considered as the main reaction channel. In addition, the dioxyrnethylene intermediate can also transfer methylene to the Ob row and break the c-O bond, thus leaving the original carbonyl O atom at the Tisc site. After the transfer of methylene, several pathways to products are available. Thus, we have found that Ob atoms are intimately involved in the photoinduced decomposition of cH2O on the futile TiO2 （100）-（1× 1） surface.

In this paper, the kinetics of pressure leaching for purification of metallurgical grade silicon with hydrochloric acid was investigated. The effects of particle size, temperature, total pressure, and concentration of hydrochloric acid on the kinetics and mechanism of iron removal were studied. It was found that the reaction kinetic model followed the shrinking core model, and the apparent activation energy of the leaching reaction was 46.908 kJ/mol. And the apparent reaction order of iron removal with pressure leaching was 0.899. The kinetic equation was obtained and the mathematical model of iron removal from metallurgical grade silicon （MG-Si） was given as follows：The values calculated from the equation were consistent with the experimental results.

Two controversies exist in the phylogeny of the derived millipedes(Diplopoda).The first is whether millipedes with a fusion ring,including Polydesmida,Spirobolida,Spirostreptida and Julida,form a monophyletic group(the ring-forming group).The second concerns the phylogenetic relationship within the three orders of Juliformia,***,Spirostreptida and *** resolve these phylogenetic controversies,we sequenced 18S and 28S rDNA from six millipede orders and retrieved several homologous sequences from *** results give robust support to the monophyly of the ring-forming group based on maximum parsimony methods,max-imum likelihood methods and Bayesian *** monophyly of the ring-forming group suggests that the fusion of segment sclerites might have occurred only once during millipede evolutionary *** also established a sister-group relationship between Spirobol-ida and Spirostreptida within Juliformia after eliminating a short-branch attraction phenomenon,which is consistent with that from the mitochondrial genome analysis.
