(Table 1) Stable isotope ratios of Globigerinoides ruber and pore water, and Cl measurement at ODP Hole 133-817C

The oxygen isotopic composition of pore waters squeezed from sediments in Hole 817C co-varies with the oxygen isotopic composition of Globigerinoides ruber below 8 mbsf. The magnitude of the variation in the pore water d18O is approximately 30% of the variation in the foraminifers. Overall, the d18O of the pore waters increases down the core, a trend that is also present in the Cl- concentrations. The variations in the d18O of pore waters may be the result of either of two phenomena. First, these may reflect original variations in the waters, the magnitude of which has been subsequently reduced by process of diffusion. Second, these may reflect recrystallization of the precursor sediment and isotopic exchange between the fluids and the recrystallized sediment. At the moment data are not available to ascertain which process is responsible although the correlation between the Cl- and the d18O data suggests that these values reflect the original composition modified by diffusion.

La jerarquía normativa en la interpretación del artículo 133 de la Constitución Política de los Estados Unidos Mexicanos

La perspectiva constitucional sobre la jerarquía normativa de las fuentes de derecho en el sistema jurídico mexicano, ha suscitado muy interesantes y variadas controversias que han llegado hasta la emisión de criterios, tanto jurisprudenciales como no jurisprudenciales, por la Suprema Corte de Justicia de la Nación. En correspondencia con ello y la necesidad que en la academia existe para aclarar a los estudiantes de derecho, de qué manera puede interpretarse la disposición constitucional que por excelencia refiere dicha temática, se presenta una propuesta de exégesis del Artículo 133 de la Constitución Política de los Estados Unidos Mexicanos, a la luz de una investigación cualitativa sustentada explícitamente en una epistemología orientada a producir conocimiento basada en la coherencia paradigmática de las posturas existentes en el ámbito del principio de supremacía constitucional y la jerarquización normativa y en la inteligencia de que no se pretende establecer reglas fijas e inmutables, sino por el contrario, se trata de una construcción donde las ideas, conjeturas, puntos de vista y reflexiones estén en constante y estrecha relación con el contexto y con los contenidos de la producción teórica sobre el tema.

The mutable nature of particle-core excitations with spin in the one-valence-proton nucleus Sb-133

The gamma-ray decay of excited states of the one-valence-proton nucleus Sb-133 has been studied using cold-neutron induced fission of U-235 and Pu-241 targets, during the EXILL campaign at the ILL reactor in Grenoble. By using a highly efficient HPGe array, coincidences between gamma-rays prompt with the fission event and those delayed up to several tens of microseconds were investigated, allowing to observe, for the first time, high-spin excited states above the 16.6 mu s isomer. Lifetimes analysis, performed by fast-timing techniques with LaBr3(Ce) scintillators, revealed a difference of almost two orders of magnitude in B(M1) strength for transitions between positive-parity medium-spin yrast states. The data are interpreted by a newly developed microscopic model which takes into account couplings between core excitations (both collective and non-collective) of the doubly magic nucleus Sn-132 and the valence proton, using Skyrme effective interaction in a consistent way. The results point to a fast change in the nature of particle-core excitations with increasing spin. (C) 2016 The Authors. Published by Elsevier B.V.

Polinização por Apis mellifera em soja em soja transgênica [Glycine max (L.) Merrill] Merrill] Roundup ReadyTM cv. BRS 245 RR e convencional cv. BRS 133.

RESUMO: O objetivo deste estudo foi verificar a influência de Apis mellifera na produção de grãos e qualidade de sementes da soja transgênica Glycine max (L.) Merrill Roundup ReadyTM e convencional. A soja transgênica foi plantada intercalada com a convencional, em 18 parcelas, em três tratamentos: gaiolas com abelhas A. mellifera, gaiolas sem abelhas e áreas descobertas, com livre visitação de insetos. Na soja transgênica, em três parcelas de cada tratamento, foi aplicado glifosato, 30 dias após a emergência. Os parâmetros analisados foram: produção de grãos; número de vagens por planta; peso de 100 sementes e porcentagem de germinação das sementes. Não houve diferença entre as cultivares, entretanto a produção de 2.757,40 kg ha-1 obtida na área coberta por gaiola com abelhas, e 2.828,47 kg ha-1 na área livre para visitação de insetos foram superiores a 2.000,53 kg ha-1 da área coberta por gaiola sem abelhas. O número de vagens por planta foi maior na área coberta por gaiola com abelhas (38,28) e área livre (32,65), quando comparado com o da área coberta por gaiola sem abelhas (21,19). O peso médio de 100 sementes e a germinação das sementes não foram diferentes entre as cultivares e nem entre os tratamentos. Conclui-se que, para as cultivares estudadas, houve benefício na produção de grãos de 37,84%, quando foi permitida a visita de abelhas. ABSTRACT. Pollination by Apis mellifera in transgenic soy (Glycine max (L.) Merrill) Roundup Ready? cv. BRS 245 RR and conventional cv. BRS 133. This research was carried out to evaluate the influence of Africanized honeybees in grain production and seed quality of Glycine max (L.) Merrill Roundup Ready? transgenic soy, as well as of conventional soy. Transgenic soy was interposed with conventional soybean, in 18 plots and three treatments: covered area with Africanized honeybees, covered area without honeybees, and uncovered area with free insect visitation. The herbicide Glyphosate was applied on three plots of each treatment of transgenic soy, 30 days after emergence. Grain production, number of pods/plant, weight per 100 seeds, and seed germination percentage were evaluated. There was no difference among cultivars; however, the production in the covered area with honeybees (2757.4 kg ha-1) and in the uncovered area (2828.47 kg ha-1) were higher than in the covered area without honeybees (2000.53 kg ha-1). The number of pods/plant was greater than in the covered area with honeybees (38.28) and in the uncovered area (32.65) as compared to the covered area without honeybees (21.19). The weight per 100 seeds seed germination did not differ among cultivars or treatments. It can be concluded that, for these cultivars, there was a rise in grain production of 37.84% when honeybee visits were allowed.
