In this paper, we have explored the effect of the characteristics of the financial behavior（FB）of the local govern- ment on the upgrading of the industrial structure （UOTIS）. By the comprehensive use of the regional and industrial data between 1998 and 2007, we have discovered that （1） the up and down of the FB of the local government has no- ticeably curbed the UOTIS, which has found the expression in the fact that the greater the fluctuation of the FB, the more the share of those industry with greater degree of complex technology; whether in terms of the absolute share in district where the industry is located or in terms of the relative share in the whole country, this conclusion is valid all the same; that （2）, compared with the expenditure of the capital construction and with the expenditure for sci- ence, education, culture and health, the vacillation of the expenditure of the administration has more negative func- tion; that （3） the rise of the level of commercialization has significantly eased the negative influence of the FB on the UOTIS. Our findings have, from the angle of the economic structure, examined closely the economic effect of the be- havior of the local government in China＇ s style of decentralization, and are a useful complement to the existing re- sults of research.

Correspondence factor analysis （CFA） was employed to study the selectivity of 14 HPLC systems. The tested LC systems were classified as reversed-phase （RP）, ion-exchange （IE） and hydrophilic interaction chromatography （HILIC） modes. It was found that the retentions of the hydrophilic solutes on HILIC column were significantly influenced by the second-order effects besides their hydrophilic properties. Organic modifiers and residue silanol groups on silica surface both participated in retention. HypersilTM amino column performed separation in the HILIC mode at appropriate conditions, and its retention mechanism was more similar to that of HILIC silica column than that of HILIC column coating poly（aspartamide） groups.

Alkoxy-L-serines are useful for peptide syntheses. The demand for alkoxy-L-serines in the pharmaceutical industries continues to increase because of their multiple physiological effects. In this research, an improved method for alkoxy-L-serines synthesis is reported. A series of substrates, DL-fl-alkoxy-a-amino propionamides, was used for the synthesis of alkoxy-serines catalyzed by Escherichia coli cells with peptidase B（PepB） activity. The results show that PepB has a high resolution activity with DL-fl-alkoxy-a-amino propionamides as substrate. Reaction conditions were optimized, i.e., DL-β-methoxy-a-amino propionamide as substrate at pH=9.0, 40 ℃ and 14 h, and the optimal reaction concentration is 400 mmol/L. The results also show that divalent metal cations exhibit different effects on the PepB activity, for example, Zn2＋ and Cu2＋ can obviously inhibit the activity of PepB, whereas Co2＋, Ca2＋, Mn〉 and Mg2＋ at low concentrations can activate PepB. This research provides access to enantiomerically enriched and valuable alkoxy-L-serines from a simple amino-amide racemate.

We revisit the Bastille Day flare/CME Event of 2000 July 14, and demonstrate that this flare/CME event is not related to only one single active region （AR）. Activation and eruption of a huge transequatorial filament are seen to precede the simultaneous filament eruption and flare in the source active region, NOAA AR 9077, and the full halo-CME in the high corona. Evidence of reconfiguration of large-scale magnetic structures related to the event is illustrated by SOHO EIT and Yohkoh SXT observations, as well as, the reconstructed 3D magnetic lines of force based on the force-free assumption. We suggest that the AR filament in AR 9077 was connected to the transequatorial filament. The large-scale magnetic composition related to the transequatorial filament and its sheared magnetic arcade appears to be an essential part of the CME parent magnetic structure. Estimations show that the filament- arcade system has enough magnetic helicity to account for the helicity carried by the related CMEs. In addition, rather global magnetic connectivity, covering almost all the visible range in longitude and a huge span in latitude on the Sun, is implied by the Nan^ay Radioheliograph （NRH） observations. The analysis of the Bastille Day event suggests that although the triggering of a global CME might take place in an AR, a much larger scale magnetic composition seems to be the source of the ejected magnetic flux, helicity and plasma. The Bastille Day event is the first described ex- ample in the literature, in which a transequatorial filament activity appears to play a key role in a global CME. Many tens of halo-CME are found to be associated with transequatorial filaments and their magnetic environment.

Background Irradiation dose and volume are the major investigated the relationships between the irradiation dose model of graded volume irradiation of the rat lung. physical factors of radiation-induced lung injury. The study and volume in radiation-induced lung injury by setting up a Methods Animals were randomly assigned to three groups. The ELEKTA precise 2.03 treatment plan system was applied to calculate the irradiation dose and volume. The treatment plan for the three groups was： group I received a ＂high dose to a small volume＂（25% volume group） with the mean irradiation volume being 1.748 cm^3 （25% lung volume）; the total dose and mean lung dose （MLD） were 4610 cGy and 2006 cGy, respectively （bilateral AP-PA fields, source to axis distance （SAD） = 100 cm, 6MVX, single irradiation）; Group 2 received a ＂low dose to a large volume＂（100% volume group） with the mean irradiation volume being 6.99 cm^3 （100% lung volume）; the total dose was 1153 cGy. MLD was 2006 cGy, which was the same as that of group 1 （bilateral AP-PA fields, SAD = 100 cm, 6MVX, single irradiation）; Group 3 was a control group. With the exception of receiving no irradiation, group 3 had rest steps that were the same as those of the experimental groups. After irradiation, functional, histopathological, and CT changes were compared every two weeks till the 16th week. Results Functionally, after irradiation breath rate （BR） increases were observed in both group 1 and group 2, especially during the period of 6th-8th weeks. The changes of BR in the 100% volume group were earlier and faster. For the 25% volume group, although pathology was more severe, hardly any obvious increase in BR was observed. Radiographic changes were observed during the early period （the 4th week） and the most obvious changes manifested during the mediated period （the 8th week）. The extensiveness of high density and the decreased lung permeability were presented in the 100% volume group, and ground glass opacity and patchy c

Amorphous rare earth-transition metal (RE-TM) alloy films with perpendicular anisotropy have been considered as more suitable materials for high recording density in the erasable magneto-optical disc. In recent years, there are considerable reports describing the magneto-optical read/write characteristics on such amorphous films, e.g. TbFeCo and GdTbFe.
