The ability of five imidazol(in)ium-2-carboxylates and dithiocarboxylates bearing cyclohexyl, mesityl, or 2,6-diisopropylphenyl substituents on their nitrogen atoms to act as NHC precursors for in situ catalytic applications was probed in ruthenium-promoted ring-opening metathesis and atom transfer radical polymerizations. Results obtained with 1:2 mixtures of [RuCl2(p-cymene)]2 and NHC•CO2 adducts were in line with those reported previously starting from preformed [RuCl2(p-cymene)(NHC)] complexes, whereas the NHC•CS2 zwitterions were almost completely inactive. To account for this dichotomy, the preparation of preformed ruthenium‚àíarene complexes from [RuCl2(p-cymene)]2 and NHC•CX2 inner salts was thoroughly investigated. As expected, imidazolium-2-carboxylates lost their CO2 moiety and afforded [RuCl2(p-cymene)(NHC)] complexes in high yields, whereas the NHC•CS2 betaines retained their zwitterionic nature and led to cationic complexes of the [RuCl(p-cymene)(NHC•CS2)]PF6 type. These stable, 18-electron species are the first examples of well-defined transition-metal complexes bearing chelating NHC•CS2 ligands. They were characterized by various analytical techniques, and the molecular structure of [RuCl(p-cymene)(IMes•CS2)]PF6 was determined by X-ray diffraction analysis. [less ▲]

Bottom friction modeling is an important step in river flows computation with 1D or 2D solvers. It is usually performed using empirical laws established for uniform flow conditions or a modern approach based on turbulence analysis. Following the definition of the flow validity field of the main friction laws proposed in the iterature, an original continuous formulation has been developed. It is suited to model river flows with a high variability of properties (water depth, discharge, roughness…). The efficiency of this new formulation, theoretically established and numerically adjusted, is demonstrated through various practical applications. [less ▲]

En numerosas novelas, Vargas Llosa aborda los mismo temas que en sus ensayos de manera que se establecen ecos entre ficción y no ficción, ecos que, de una u otra manera, apoyan implícitamente la verdad de los textos literarios por la de los ensayos historiográficos. También el hecho de que el narrador en sus novelas a menudo tenga rasgos autobiográficos evidentes de su autor contribuye a borrar las fronteras entre universo de ficción interno y universo externo. Además, en varias novelas Vargas Llosa tiende a borrar las fronteras entre los géneros, y acerca la novela al ensayo Al comparar El hablador, novela que publicó en 1987, con el ensayo José María Arguedas o las ficciones del indigenismo, de 1996, nos interrogamos acerca de la relación que existe entre las ideas sobre el indigenismo expresadas por Vargas Llosa en la ficción y fuera de ella.

The objective of this paper is to examine nonlinear normal modes and their bifurcations in cyclic periodic structures. The nonlinear normal modes are computed using a numerical technique that combines shooting and pseudoarclength continuation. Unlike perturbation techniques, the resulting algorithm can investigate strongly nonlinear regimes of motion. This study reveals that modal interactions may occur without necessarily having commensurate natural frequencies in the underlying linear system. In addition, a countable infinity of such modal Q2 interactions are shown to exist in the system. [less ▲]

We investigate the flux pinning and dynamic properties of superconducting vortices in an Al film with an array of magnetic bars deposited on top. The dimensions of each bar are chosen in such a way that they host a single magnetic domain. These micromagnets are distributed periodically in a rectangular array with 0.5 mu m separation parallel to the longest side of the bars and displaced laterally by a distance w. We show that, for w > Lambda, where Lambda is the effective field penetration depth, the pinning strength is almost independent of w whereas the critical temperature at zero field, T(c)(0), decreases as similar to w(-1). For w < Lambda the opposite behavior is observed, i.e. T(c)(0) seems to saturate to a nearly w-independent value and the transition from large to small w is accompanied by a large suppression of the critical current j(c) together with a clear change in the shape of the current-voltage characteristics. In particular, the substantial weakening of the pinning potential for w < Lambda gives rise to an unexpected flux flow response. The field evolution of this regime allows us to determine whether the magnetic bars induce vortex-antivortex pairs in the system. The present findings suggest that practical application of magnetic pinning centers are restricted to low field values. [less ▲]

The study was conducted at the Rukoko station located at 21 km North-Western of Bujumbura in the Imbo natural region, in the South of Rusizi River. The objective was to assess the effects of year of lactation, genetic group, lactation length, season and parity on the Daily Milk Yield (DMY) of Jersey (J) x Sahiwal (S) x Ankole (A) crossed cows. Milk yields were obtained from cows that have been both Suckled and Milked (SM) or only Milked (M). Data were analyzed using the procedure GLM in SAS on SM and M cows, separately. All factors affected significantly DMY (p<0.001). A significant increase was observed from 1989-1991 due to the improvement of management techniques. During this period, the production raised from 10.07 +/- 0.22 L-11.50 +/- 0.17 L day(-1) for SM cows. Unfortunately, the 1993 civilian war destabilized the managerial techniques and consequently, the milk production decreased. Highest milk yields were observed in crossed cows with 50% of Jersey and 50% of Sahiwal inheritances. Peak yields occurred at the 43rd (12.67 +/- 0.42 L) and 56th (6.42 +/- 0.45 L) days in milk for SM and M cows, respectively. Milk production was significantly higher in January (11.04 +/- 0.23 L day(-1)), in the middle of the rainy season, than in July (7.02 +/- 0.18 L day(-1)), in the middle of the dry season. Milk yield in SM cows increased from 8.15 +/- 0.17 L-9.46 +/- 0.16 L day(-1) during the 1st and the 2nd lactation, respectively. [less ▲]

In birds, corticosteroid-binding globulin (CBG) binds corticosterone, progesterone and testosterone. The concentration of each ligand can alter the binding of the other ligands through competitive interactions. Thus, an increase in corticosterone or progesterone may displace testosterone bound to CBG, leading to an increase in bioactive free testosterone levels without affecting total testosterone levels in the circulation. Aggressive interactions increase plasma total testosterone levels in some birds but not in others. Here, we tested the hypothesis that aggressive encounters in the late breeding season would not increase total testosterone levels in plasma, but would alter CBG, total corticosterone or total progesterone levels in such a way as to modify the number of available binding sites and therefore occupancy by testosterone. A marked decrease in CBG occupancy by testosterone would indirectly suggest an increase in free testosterone levels in plasma. Wild male white-crowned sparrows were exposed to a simulated territorial intrusion (STI) or control for 30 min. Subjects were then caught and bled. We measured CBG using a ligand-binding assay and corticosterone, progesterone and testosterone using highly sensitive radioimmunoassays. STI significantly increased aggressive behaviors but did not affect plasma total testosterone levels. STI significantly increased plasma CBG and total corticosterone levels and decreased plasma total progesterone levels. We predict that CBG occupancy by corticosterone will increase slightly following an aggressive encounter. However, this small change is unlikely to increase free testosterone levels, because of the large number of seemingly unoccupied CBG binding sites in these subjects. [less ▲]
