      he work described in this paper has demon- strated that chemically modified Corsican pine sapwood with a homologous series of linear chain carboxylic acid anhydrides provided bioprotection against the subterranean termites ...

    • Systematization of basic divergent integrals in perturbation theory and renormalization group functions 

      Brito, L.C.T.; Fargnoli, H.G.; Scarpelli, A.P. Baêta; Sampaio, Marcos; Nemes, M.C. (Elsevier, 2009-02)
      We show that to n loop order the divergent content of a Feynman amplitude is spanned by a set of basic (logarithmically divergent) integrals I (i) log(λ2), i = 1, 2,...,n, λ being the renormalization group scale, which ...

    • Chemistry in Second Life 

      Lang, Andrew SID; Bradley, Jean-Claude (Springer Open, 2009-10)
      This review will focus on the current level on chemistry research, education, and visualization possible within the multi-user virtual environment of Second Life. We discuss how Second Life has been used as a platform ...

    • Uniqueness of moving boundary for a heat conduction problem with nonlinear interface conditions 

      Wei, T. (Elsevier, 2010-01)
      In this paper, based on the maximum principle and the unique continuation theorem, we present a uniqueness result for a moving boundary of a heat problem in a multilayer medium with nonlinear interface conditions.
