conclusions the presence of bft gene in b. fragilis isolates wouldnot certainly result in diarrheaamong patients. there is not enough accordance between ddm and swedish e tests for antimicrobial susceptibility of b. fragilis for some antibiotics, although in other cases a good agreement was observed. background enterotoxigenic bacteroides fragilis (etbf) are one of the most important anaerobic ...

Perrin et al. (1995) and Geubelle and Rice (1995) have introduced a spectral method for numerical solution of twoand three-dimensional elastodynamic fracture problems. The method applies for ruptures confined to a plane separating homogeneous elastic half spaces. In this method, the physical variables, such as the traction components of stress and displacement discontinuity on the rupture plane...

In this paper we introduce a variant of the three-field formulation where we use only two sets of variables. Considering, to fix the ideas, the homogeneous Dirichlet problem for −∆u = g in Ω, our variables are i) the approximations uh of u in each sub-domain Ωs (each on its own grid), and ii) an approximation ψh of u on the skeleton (the union of the interfaces of the sub-domains) on an indepen...

Based on the concept of discontinuity displacement, an analytical solution for cracked thin plates has been derived in which displacements and stresses in a solid can be expressed by the linear distributed discontinuity displacements on the whole boundary. By way of the potential variational principle and the analytical solution newly developed, a boundary element model for 2D multiple crack pr...

Geothermal energy is one of the most stable and clean solutions to replace traditional fossil fuel resource. The South Meager geothermal prospect, located in southwestern British Columbia, contains large resources due recent volcanic activities. in-situ stress state prospective area that influences characteristics fractures, thus affecting productivity, remains unknown. In this paper, we presen...

in this paper, the interface crack of two non-homogenous functionally graded materials is studied. subsequently, with employing the displacement method for fracture of mixed-mode stress intensity factors, the continuous variation of material properties are calculated. in this investigation, the displacements are derived with employing of the functional graded material programming and analysis o...

The Data Distribution Management (DDM) services, one category of HLA management services, control filters for data transmission and reception of data volume among simulators. In this paper, we propose design concept of DDM and show its implementation for RTI. The design concept of DDM is to minimize total amount of message that each federate and a federation process generate using the rate of R...

Distributed Data Mining (DDM) is the process of mining distributed and heterogeneous datasets. DDM is widely seen as a means of addressing the scalability issue of mining large data sets. Consequently, there is an emerging focus on optimisation of the DDM process. In this paper we present cost formulae for estimating the communication and computation time for different distributed data mining s...

static deformation modulus is recognized as one of the most important parameters governing the behavior of rock masses. predictive models for the mechanical properties of rock masses have been used in rock engineering because direct measurement of the properties is difficult due to time and cost constraints. in this method the deformation modulus is estimated indirectly from classification syst...
