The Robinson annulation is a three-step process involving a Michael addition followed by an internal aldol condensation and a dehydration. Under appropriate experimental conditions, it is possible to stop the reaction after every step and to isolate the three products separately. This feature is particularly attractive in the frame of an organic chemistry course. It allows students to confirm experimentally the validity of the stepwise mechanism and to get a more thorough understanding of the whole process. It also permits them to synthesize a rich set of related molecules that can be compared and characterized through various analytical techniques. Thus, a stoichiometric mixture of chalcone and ethyl acetoacetate was reacted in ethanol. Depending on the quantity of barium hydroxide monohydrate used as catalyst, the reaction time, and the temperature, three different products were obtained. Their full IR, 1H, 13C, COSY, NOESY, and HETCOR NMR spectra are supplied. Examination of the spectroscopic data helps uncover many challenging structural analysis problems. Among them, the diastereoselective formation of chiral centers during the annulation process, the distinction between axial and equatorial substituents on a cyclohexane ring, and the possibility of a keto-enol tautomerism are extensively discussed.

Purpose - The paper seeks to develop dual 3D finite element (FE) formulations for modeling both inductive and capacitive effects in massive inductors, in particular micro-coils. The paper aims to build circuit relations relating the voltages and the currents in such inductors to be used in circuit coupling. Design/methodology/approach - A circuit relation involving a unique voltage and complementary inductive and capacitive currents is defined for each inductor. the inductive circuit relation is first classically obtained by a FE magnetodynamic model. Then, the capacitive relation is obtained through a FE electric model, using sources evaluated from the first model. The conformity is defined on one hand for the magnetic flux density and the electric field, and on the other hand for the magnetic field and the electric flux density. Mixed FE, i.e. nodal, edge and face elements, are used to satisfy each chosen conformity level for the unknown fields and to naturally define the involved global quantities, i.e. the voltages, currents and charges. Findings - This contribution points out the interest of satisfying conformity properties for the coupled magnetic and electric problems. An accurate computation of these effects is obtained in the critical frequency range of their strong interaction. In addition, the complementarity of dual solutions gives the possibility to estimate the discretisation error. Originality/value - The mathematical and discretisation tools for any wished conformity level are unified for naturally coupling magnetic and electric problems. The global quantities basis functions involved in the FE circuit relations benefit from a significant support reduction, which facilitates their evaluation and gives them direct physical interpretations.

Au Cameroun, le processus de la gestion durable des forêts a conduit une société d'exploitation forestière industrielle à procéder depuis quelques années, en partenariat avec des institutions de recherche locales ou internationales, à des études scientifiques d'espèces identifiées comme vulnérable dans ses concessions. A ce titre, la détermination de techniques d'interventions sylvicoles pragmatiques ainsi que l'écologie d'espèces telles que l'iroko, Milicia excelsa sont étudiées afin de comprendre et de remédier au faible niveau de régénération naturelle. Les observations portent d'une part sur les performances de fructification (phénologie, pluie de graine, germination) et de dispersion des semences, et d'autre part, sur la dynamique de populations naturelles de juvéniles. Etant donné qu'une faible performance de régénération peut être due à la consanguinité, elle-même résultant de la raréfaction des populations, il est prévu également une analyse de la diversité génétique locale. Parallèlement, des essais de plantations permettent de juger des effets de différents facteurs abiotiques ou biotiques sur la dynamique des plantules. [less ▲]

A method for gaining information about the phonon-number moments and the generalized nonlinear and linear quadratures in the motion of trapped ions (in particular, position and momentum) is proposed, valid inside and outside the Lamb-Dicke regime. It is based on the measurement of first time derivatives of electronic populations, evaluated at the motion-probe interaction time tau = 0. In contrast to other state-reconstruction proposals, based on measuring Rabi oscillations or dispersive interactions, the present scheme can be performed resonantly at infinitesimal short motion-probe interaction times, remaining thus insensitive to decoherence processes.

The development, the establishment and the embryonic survival at early stages of gestation are depending on an intimate dialogue between the embryo and his mother. For the embryo part, it is especially the trophoblast, or the future placenta, which plays a key role in initializing pregnancy. The placenta emits many signals of various chemical natures ( steroids, prostaglandins, peptides, proteins), some of them, e. g. the interferon tau, determine the maintenance of the corpus luteum at the beginning of gestation. Until now, although having raised many speculations, the earliest of these signals were not identified in peripheral circulation. Consequently, they cannot be used as a pregnancy diagnosis or to indicate embryonic mortality. However, since the eighties, the specific proteins "associated with pregnancy", produced by the trophoblastic cells are used as tool for breeding management. Most of these molecules are present in peripheral circulation. In this review, we will describe the major mechanisms associated with the maternal recognition of the gestation and their possible applications as pregnancy diagnosis tool in the cow. [less ▲]
