The aims of this study was to investigate the persistence and the growth of culturable bacterial indicators （CBI） including total coliforms （TC） and faecal coliforms represented by Escherichia coli, enterococcus （EnT）, and aerobic mesophilic bacteria （AMB） in the surface sediments and the water column of Vidy bay fLake Geneva, City of Lausanne, Switzerland）. The study was carded out for 60 d using microcosms containing Sewage Treatment Plant （STP） effluent and nonsterile water without CBI, as well as contaminated and non-contaminated sediments. The effects of water temperature and of organic matter associated with sediments on the survival of CBI in the sediments and the water column were observed. The number of CBI colonies in the contaminated sediments of Vidy bay and in the STP effluent was almost identical in the order of 10^5-10^7, 10^4-10^6, 10^5-10^5, and 10^4-10^7 CFU/100 g sediment or/100 mL water for TC, E. coli, EnT, and AMB respectively. A degradation of CBI was observed in the sediments where organic mater content was low and in the water column at a temperature of 10℃ after 5 d of experimentation. In addition, a growth of CBI was observed in the sediment which is rich in organic matter at 20℃. The results of this study indicate：（1） the higher concentrations of the CBI observed in different points in the water column of Vidy bay may not be explained only by the recent contribution of the three potential sources of the bay contamination including STP and the Chamberonne and Flon rivers, but also by the persistence, removal from sediment and multiplication of CBI in the sediment and water column; （2） the sediment of Vidy bay constitute a reservoir of CBI and can even support their growth; and （3） the CBI not only survive in sediments, but also can be remobilized and increased in the water column, therefore, it become a permanent microbiological pollution in Vidy bay.

Objective: To investigate the clinical performance of implants with chemically modified surfaces in irradiated bone in a period of five-years. Patients & Methods: 15 (6 females, 9 males, 50.2 years with a range of 38 - 60 years) patients who had been operated for oral tumors and had undergone radiotherapy were enrolled and 40 SLActive surface implants were placed (24 in the maxilla, 16 in the mandible). Implants were allowed to integrate for a period of 90 days and the stability of the implants was measured with resonance Frequency Analyzer/Osstell? Mentor (Integration Diagnostics, Savedalen, Sweden) at implant placement, 30 days later and at the end of the 90th day. Patients follow up periods after the implant placement varied from 20 months to 60 months (mean: 45 months). results: Two implants were lost in maxilla in healing period as a result of osseointegration failure. The survival rate was 95%. During the observation period, totally 4 implants were lost. The overall success rate was 90%. 3 of the lost implants were in maxilla and one was in mandible. The initial ISQ values of the implants differed from 20 - 71;the second values were between 24 - 71 and the last values were between 30 - 89. The implants which were lost could not show a value greater than 35. Conclusion: There was no any complication on the SLActive surface implant placed bones due to irradiation. Within the limitations of this study, it may be concluded that osseointegrated implants can be placed in irradiated bones, unless a careful patient selection and treatment planning is performed.

Partition property plays a central role in domain decomposition methods. Existing theory essentially assumes certain ellipticity. We prove the partition property for prod lems without ellipticity which are of practical importance. Example applications include implicit schemes applied to degenerate parabolic partial differential equations arising from superconductors, superfluids and liquid crystals. With this partition property, Schwarz algorithms can be applied to general non-elliptic problems with an h-independent optimal convergence rate. Application to the time-dependent Ginzburg-Landau model of superconductivity is illustrated and numerical results are presented.

What can routh table offer in addition to stability?

This paper develops a simple structural model of alternative modes of governance of transactions to formalize some distinguishing aspects of the transaction cost *** is shown that each mode of governance is associated with a different degree of incentive intensity,which in turn is attributable to the difference in court access and in the control of *** the model is very simple and stylized with quite intuitive results,it does yield some interesting implications that are not readily clear from reduced-form models.

控制理论与应用（英文版） 2003年第1期1卷 9-16页

routh stability test is covered in almost all undergraduate control texts. It determines the stability or, a little beyond, the number of unstable roots of a polynomial in terms of the signs of certain entries of the routh table constructed from the coefficients of the polynomial. The use of the routh table, as far as the common textbooks show, is only limited to this function. We will show that the routh table can actually be used to construct an orthonormal basis in the space of strictly proper rational functions with a common stable denominator. This orthonormal basis can then be used for many other purposes, including the computation of the H2 norm, the Hankel singular values and singular vectors, model reduction, H∞ optimization, etc. Keywords routh stablity criterion - Orthonormal basis - root-mean-squared value - Hankel operater - nehari problem - Model reduction This work was supported by the Hong Kong research Grants Council.
