Genomic organization of EDSV strain AA-2

The genomic organization of egg drop syndrome virus strain AA-2 isolated in China is reported here. The genome was found to be 32 838 bp in length, approximately 2 kb shorter than those of the human subgenus C adenoviruses. Analysis of open reading frames indicated that the genes for major viral structural proteins (55 K, Penton base, pⅦ, pⅩ, pⅥ, Hexon, 100 K, pⅧ and Fiber), as well as EP, DNA polymerase and ⅣaⅡ are present in the expected locations in the genome. EDSV possesses no identifiable E3 and E4 regions and most proteins encoded by E3 and E4 regions of other adenoviruses genome were not presented in EDSV.     

Carbazole-type compounds in crude oils

Carbazole-type compounds were analyzed using GC and GC-MS-MS. A relatively high concentration of carbazole-type compounds was detected in crude oils of different types (marine and non-marine) and different maturities (low mature and mature) in Tarinl. Liaohe and Keilu basins. The results suggest the ratios of 1, 8-dimethyl-/2, 7-dimethylcarbazole and benu, [a] carbazole/benzo [e] carbazole might be taken as petroleum migration parameters.     

Explicit analytical solutions of non-Fourier heat conduction equation for IC chip

Four basic explicit analytical solutions of non-Fourier heat conduction equation simulating IC chip thermal condition are derived. Some other analytical series solutions can also be derived with the above-mentioned basic solutions. Analytical solution has its own irreplaceable important meaning in theory. In addition, as the standard solution to check the accuracy, convergence and effectiveness of various numerical computational methods and their differencing schemes, grid generation ways and so on, the analytical solution is very useful also for the newly rapidly developing computational heat transfer.     

The discovery of early Permian reef belt in east Kunlun and its significance

The early permian reef belt is distributed in the southern side of eastern Kunlun, north area of Qinghai-Tibet Plateau. The core-reef facies of thc reel extends from Tuosuo Lake to Huashixia. Lots of reef breccia was found at the southern slope of the mre-reef belt, and to the north of the reef belt there is back-reef limestone. Cacisponges, hydrozoa, bryozoa,Tabulozoa, Tubiphytes and red algae are the main frame-building organisms.Archaeolithoporella, laminated blue-green algaes,Tabulozoa andTubiphytes played a role of binding or encrustating. There are many kinds of epibiont in the mf, including brachiopod, gasterid, foraminifera, echinoderm and simple coral. The type and the characteristics of the reef-building organisms in eastern Kunlun and Animaqing are basically thr same as those in the south of Chi     

Stability of the Sarcin/Ricin domain of 28S RNA in rat ribosome under hydrostatic pressure

Under 2 100 bar of hydrostatic pressure, KNA N-glycosidase can still cleave the N-C bond of adenosine at position 4324 in R/S domain of 28S RNA in rat ribosome, demonstrating that high pressure has no effect on the tertiary structure of S/R domain.
