In the context of long-term degradation porous media, coupling between fracture mechanics and reactive transport is investigated. A model in a cracked discontinuous heterogeneous medium proposed. The species through along crack network are taken into account multibody approach. dedicated geochemistry solver developed allows to take significant number chemical reactions. validated via benchmark ...

The local plasticity and associated microstructure evolution in Fe-5Mn-0.1C medium-Mn steel (wt.%) were investigated this study. Specifically, the micro-deformation mechanism during Lüders banding was characterized based on multi-scale electron backscatter diffraction measurements channeling contrast imaging. Similar to other steels, showed discontinuous macroscopic deformation, preferential pl...

background and objectives: virosomes are virus like particles (vlp) assembled in-vitro. influenza virosomes maintain the cell binding and membrane fusion activity of the wild type virus but are devoid of viral genetic material or internal proteins. influenza virosomes mimic the natural antigen presentation route of the influenza virus. materials and methods: virosomes were prepared by membrane ...

studies relating form and functions of cities indicate sprawl as an intriguing research issue, especially for certain typologies of cities. although with inherent differences on a local scale, mediterranean cities offer a kaleidoscopic overview of sprawl morphologies that require dedicated monitoring tools. the present study provides an original assessment of recent urbanization processes in th...

By generalizing the notion of location of a constituent to allow discontinuous Ioctaions, one can describe the discontinuous constituents of non-configurational languages. These discontinuous constituents can be described by a variant of definite clause grammars, and these grammars can be used in conjunction with a proof procedure to create a parser for non-configurational languages.

We study the problem of estimating the size of an inclusion embedded inside a two dimensional body with discontinuous conductivity by one voltage-current measurement. This problem is practically important because the conductivity of a human body is discontinuous. The proofs rely on quantitative uniqueness estimates for the conductivity equation with discontinuous coefficients.

We present the semidiscrete and the backward Euler fully discrete discontinuous mixed covolume schemes for parabolic problems on triangular meshes. We give the error analysis of the discontinuous mixed covolume schemes and obtain optimal order error estimates in discontinuous H(div) and first-order error estimate in L(2).

In this paper we give stability analysis and error estimates for the recently introduced central discontinuous Galerkin method when applied to linear hyperbolic equations. A comparison between the central discontinuous Galerkin method and the regular discontinuous Galerkin method in this context is also made. Numerical experiments are provided to validate the quantitative conclusions from the a...

DNA polymerases catalyze the synthesis of DNA using a continuous uninterrupted template strand. However, it has been shown that a 3'-->5' exonuclease-deficient form of the Klenow fragment of Escherichia coli DNA polymerase I as well as DNA polymerase of Thermus aquaticus can synthesize DNA across two unlinked DNA templates. In this study, we used an oligonucleotide-based assay to show that disc...

Intuitively, discontinuous changes can be seen as very rapid continuous changes. A couple of alternative methods based on this ontology are presented and compared. One, called the approximation method, approximates discontinuous change by continuous function and then calculates a limit. The other, called the direct method, directly creates a chain of hypothetical intermediate states (mythical i...
