Stochastic subspace identification was utilized to extract modal parameters from the structural response signals,by which the modal flexibility curvature (MFC) was constructed to detect structural damage.A numerical model of simple beam using line elements was employed to compare the results between the displacement modes and strain modes by means of the above procedure.In addition,a simple beam model constructed by solid elements was also used to investigate the effect of recorded locations of strain signals on the damage identification.The results show that the strain modes are better than displacement modes in locating damage under the effect of noise;however,the recorded places of strain signals should be near the damaged parts.

A total of 9 bacterial strains were isolated from rhizosphere of Gynostemma pentaphyllum through enrichment on 1-aminocyclopropane-1-carboxylate (ACC) as a sole nitrogen source.ACC deaminase assay showed that all isolates differed in their potential for ACC deaminse activity,among which 3 strains were positive for siderosphere by chrome azurol S (CAS) assay.Inoculation of rice seedlings with 7 ACC deaminase-containing strains had significant effect on root elongation and root fresh weight,among which the strain JDG127 caused 1.6-fold increase in root length and root fresh weight over uninoculated control.Based on the physiological and biochemical characteristics in combination with 16S rRNA gene sequences analysis,the 9 ACC deaminase- containing strains were identified as Stenotrophomonas (1 strain),Paenibacillus (1 strain),Bacillus (1 strain),Enterobacter (2 strains) and Acinetobacter (4 strains).The results indicated that the siderosphere producing ability of rhizobacteria may be correlated with their plant growth-promoting ability when compared to their ACC-deaminase activity.

To observe the pathologic changes and the expression of nuclear factor-kappa B(NF-κB)after diffuse axonal injury(DAI) in rats,its mechanism is firstly explored.The rat DAI model was established.Immunohistochemical SABC method was used to observe the expression of NF-κB,combining Glees-Marsland and Weil staining to observe the pathologic changes in different stage of DAI.Swollen and ruptured axon were found in brain tissue 1 h after DAI,and myelin sheath showed edema,delamination,marked axonal retraction ball and screen shape changes were detected after 24 h,and those morphological changes reached the peak after 72 h.The expression of NF-κB could be detected 1h after injury,the positive cells increased after 3 h,peaked after 24 h,and kept this tendency for 72 h.The positive cells decreased after 7 d.The control group showed negative staining.The findings showed that the expression of NF-κB increased in rat DAI model.The NF-κB may play an important role in secondary axonal injury.

In the past more than 10 years,unique styles of education have been formed and much experience has been accumulated in the Sino-foreign cooperative education projects conducted in the universities or colleges in Hunan province.However,with the development of higher education and the change of study abroad market,there are some problems affecting sustainable development of the projects,including the external and internal factors.The external factors include the decreasing number of college entrance exam candidates,the increasing college entrance rate of the country over the years and the more and more younger-age people going abroad and so on.The internal factors include the lower levels of foreign partners,the inferior quality of the admitted students,the less high quality courses from the foreign partners,the less specialized courses taught in English or bilingual and too much attention to exams in English language.Thus,on the one hand,it is necessary to make the projects fit the new situation,such as offering more specialized courses taught in English or bilingual and paying more attention to students’ communication abilities.On the other hand,it is necessary to expand the projects for exchange students,and establish cooperative education institutions with the famous foreign universities in Hunan Province.
