Abstract:

This paper provides a description of the articulated species of the Tribe Janieae (Corallinales, Rhodophyta) in the Pacific coast of Baja California and Gulf of California, Mexico. This taxonomic report is based on newly collected data in the study area and material currently housed at several herbaria. As a result of the present study, the record of the tribe Janieae is represented at the Pacific coast of Mexico for one genus: Jania J. V. Lamouroux with nine species. Morphological, reproductive and anatomical descriptions are provided in detail. In addition, keys for determination are included, as well as habitat, nomenclature, comparisons with other species and information on distribution. Instead of eleven species of Jania currently recorded for the study area, we recognize only nine. Jania verrucosa is restricted to the occidental coast from the Peninsula of Baja California. The remainder of the species commonly occurs in the Gulf of California and the Pacific coast of Baja California’s Peninsula. On the other hand, the gametangial thalli of J. adhaerens and tetrasporangial conceptacle in J. longiarthra are reported for the first time in Mexico.

Abstract: Con el fin de identificar y caracterizar la composición de especies de la zona submareal de la bahía de Todos Santos, Baja California, México; se realizaron muestreos de macroalgas marinas bentónicas en 7 sitios durante 1995-2000. Como resultado de 25 buceos Scuba entre 3 y 33 m de profundidad se encontraron 150 especies de macroalgas para el área de estudio; 10 son Chlorophyta, 26 Phaeophyta y 114 Rhodophyta. Del total, 47 son registros nuevos para el área de estudio y 2 de éstos, Faucheocolax attenuata Setchell y Minium parvum R.L. Moe, son nuevos para la flora marina del Pacífico de México. Se incluye una revisión de las investigaciones en las que se han considerado las macroalgas presentes en la bahía de Todos Santos y una discusión sobre la composición de las especies encontradas, su distribución vertical y reproducción, así como sobre las especies epífitas y parásitas del área. In order to identify and characterize the species composition of the subtidal zone of the Todos Santos Bay, Baja California, Mexico, benthic marine macroalgae were sampled at 7 sites from 1995 to 2000. As a result of 25 scuba at derds for the study area, of which Faucheocolax attenuata Setchell and R.L Moe Minium parvum are new to the marine flora of Pacific Mexico. We include a research that consider the macroalpths between 3 and 33 m we found a total of 150 species of macroalgae for the study area, of which 10 are Chlorophyta, 26 Phaeophyta and 114 Rhodophyta; 47 species represent new recogae in the Todos Santos Bay and a discussion on the composition of species found, its vertical distribution and reproduction, particularly the species epiphytes and parasites present in the study area.

Abstract: Polyembryony is the formation of several embryos in a seed and is present in many plants, included maize. In the present study the chemical, physical and rheological properties of nixtamalized maize flour, masa and tortilla of maize kernel with high polyembryony levels and brachytic population were evaluated and compared to three control populations. The nixtamalized maize flour and tortillas of brachytic population were similar to the control population in most of the tests. The retrogradation in nixtamalized maize flour of brachytic population was lower than the control nixtamalized maize flour showed 191.77 RVU; the protein content of nixtamalized maize flour of brachytic population was greater and content of ash in tortilla was lower than the controls. The flour made from maize brachytic population is an option for the flour and tortilla industry.

Abstract: Se realizaron muestreos de Amphiroa beauvoisii (Corallinales, Rhodophyta) en diversas localidades de las costas del Pacífico y Caribe mexicano de 1994 a 2007 y se efectuó una extensa revisión bibliográfica de los trabajos en los que se cita Amphiroa beauvoisii. Asimismo, se revisaron los ejemplares depositados en herbarios nacionales y extranjeros, con el propósito de determinar la distribución latitudinal, y la variación morfológica y reproductiva de esta especie. El análisis de la información nos indica que se encuentra ampliamente distribuida en la costa del Pacífico desde islas Coronados, Baja California hasta La Ventosa, Oaxaca, siendo muy frecuente en el golfo de California y en los estados de Jalisco, Guerrero y Oaxaca, mientras que en la costa atlántica su distribución se encuentra restringida a los arrecifes coralinos de Yucatán y Quintana Roo. Se describen en forma detallada los caracteres morfo-anatómicos y reproductivos. En general se observó que los talos tetrasporangiales y bisporangiales son frecuentes, de mayor talla y más ramificados que las plantas gametangiales. El material examinado mostró que en la costa del Pacifico se encuentran los talos tetrasporangiales, bisporangiales y gametangiales, mientras que en la costa del Caribe mexicano sólo se presentan poblaciones tetrasporangiales. Se registra por primera vez la fase gametofitica masculina y femenina de A. beauvoisii en poblaciones mexicanas.

Persona , 2001,
Abstract: Se ha explorado 62 estudiantes universitarios en la comprensión de tres tipos de exto: narrativos, argumentativos y expositivos. Se utilizó un instrumento que aplica la técnica de neologismos para medir el rendimiento diferencial en los tres tipos de superestructura textual. Se halló que el tipo de texto que presenta mayor 8dificultad es el expositivo, siguiéndole el argumentativo y el narrativo. Se da una explicación evolutiva a este resultado. Además se ha encontrado que factores muestrales como género, edad, tipo de estudio, rendimientos tanto escolares como de ingreso a la universidad, y el nivel educativo de los padres no presentan diferencias significativas entre sí. Finalmente, la técnica de neologismos probada presenta un buen nivel de confiabilidad y validez.

Abstract: sorghum (sorghum bicolor (l) moench) is one of the main basic foods forthe poorest people in the world, suffering from a situation of increased food insecurity. this crop is adapted to a warmer and drier agro-ecological environment, where it's difficult to grow other cereals. the formation of outstanding genotypes requires to evaluating the genetic materials in different environments and determines their genotype-environment interaction. the objective was to detect and analyze the genotype-environmentofagroup of recombinant inbred lines and select the highest potential to be used in the production of biofuels. 135 recombinant inbred lines of sorghum were evaluated at different locations during the years 2006, 2007 and 2008. data from seven variables were analyzed as corresponding to an experiment in randomized block design in each of several environments. genotype-environment interaction was analyzed using the ammi model. it was highly significant, scoring the recombinant inbred lines, selecting them by its size and selecting those with less magnitude, the best environment forthe proper development of recombinant inbred lines were determined and, 13 lines with higher sugar content were selected measured in °bx.
Lo local en la teoría y en la política
González Meyer,Raúl;
Polis (Santiago) , 2009, DOI: 10.4067/S0718-65682009000100005
Abstract: in this article it is supported and it promotes the need for comprehension the 'local' as scale of the 'social', and as a resultant social production of the action and interaction of agents who act from different scales, interests and objectives. it also argues that it has been an analytic field of low development in chile and latin america, although several approximations can be inventoried that direct or indirectly have been referred to it in the past. on the other hand, a political orientation is encouraged and is made problematic that within a level of "styles of development", would value local endogenous dynamics, that is to say, with local agents as protagonists. lhis is supported in the necessity of making visible and to project peripheral powers shadowed by an"intellectual centralism", because of the importance that local territories have in our lives, because of the need to settle counts with the construction of "the national" which opressed diversities and, finally, to avoid the imposition of rationalities and global agents who, under a speech of universality, will impose private interests.
Rigorismo ascético y polémica antijudía en el presbítero Eutropio (siglo V)
González Salinero, Raúl
Hispania Sacra : Revista de Historia Eclesiástica , 2004,
Abstract: The fifth century presbyter Eutropius, ecclesiastical writer probably native of Hispania or Aquitaine, was a paradigmatic example of how Late Antique patristic literature linked the ascetic ideal with the anti-Jewish polemics. His spiritual interpretation of the true circumcision> as a kind of fuga mundi demands, at the same time, an absolute repulse of the Jewish circumcision and any Judaizing influences. El presbítero Eutropio (siglo V), escritor eclesiástico de probable origen hispano o aquitano, constituye un ejemplo paradigmático de la literatura patrística tardoantigua que vincula el ideal ascético con la polémica antijudía. Su interpretación espiritual de la verdadera circuncisión como una especie de fuga mundi exige, al mismo tiempo, un rechazo absoluto de la circuncisión judía y de todas las influencias judaizantes.
