The 1,3-dipolar cycloaddition between glycine-derived azlactones with maleimides is efficiently catalyzed by the dimeric chiral complex [(Sa)-Binap·AuTFA]2. The alanine-derived oxazolone only reacts with tert-butyl acrylate giving anomalous regiochemistry, which is explained and supported by Natural Resonance Theory and Nucleus Independent…

CONTEXTE : La mortalité infantile a diminué au Canada depuis les
années 1990 et 2000 mais nous ignorons si toutes les classes socioéconomiques
ont bénéficié également de ce progrès.
OBJECTIFS : La présente étude portait sur les différences entre les…

This is the pre-peer reviewed version of the following article: The potential of parasitoid Hymenoptera as bioindicators of arthropod diversity in agricultural grasslands 2011, 48 (2):382 Journal of Applied Ecology, which has been published in final form at: http://doi.wiley.com/10.1111/j.1365-2664.2010.01937.x, 1. As…

This paper describes two in vitro regeneration systems through direct and indirect organogenesis in Pinus brutia using fascicles aseptic cultures as explants. Mechanical scarification and gibberellic acid (GA3) were evaluated on in vitro seed germination. Scarification was the treatment that…

This paper mainly concerns the study of a large class of variational systems governed by parametric generalized equations, which encompass variational and hemivariational inequalities, complementarity problems, first-order optimality conditions, and other optimization-related models important for optimization theory and applications. An…

In this interview, Adrian Lee talks candidly about the current challenges facing police and public sector leadership. The Chief Constable's studies of theology, philosophy and law prior to him joining the police service have shaped and formed his sense of…

Silver halide sensitized gelatin (SHSG) is one of the most promising techniques for the fabrication of transmission holographic optical elements, achieving relatively high sensitivity of photographic material with the low scattering and high light stability of dichromated gelatin. In this…

In this work we present a discrete event model to design and implement a real time system simulator. This kind of software is useful to verify and evaluate algorithms and models, and to compute performance metrics. The discrete event model…

The main purpose of this book is to present the contents of an introductory course in databases. In this regard, one can find a number of material validity and recognized different scopes. This work is developed under the guidelines that…

There are few practical tools for how we can develop the trust needed to be able to work with ourselves and our colleagues, nor on how
we can develop the organisational conditions that enable us to trust ourselves and others,…
