    Efecto de la competencia en el crecimiento de variables dasométricas de Pinus pseudostrobus Lindl. en el sur de Nuevo León, México. por Rodríguez Alemán, Analí Celene

    Publicado 2017
    “…The data were obtained from 53 random sampling sites of 400, 500 and 1000 mts 2 from which the dasometric variables were obtained: normal diameter, total height, clean shaft height and cup diameter as well as distance between trees and The competition effect was analyzed by 6 distance-dependent competition indices, and the 3 criteria for selecting competing trees were also evaluated. It was found that the best results were provided by the IC1 competition index Alemdag (1978), for the two selection criteria used since it was the index that best explained the growth-index relationship of competence with a coefficient of determination that ranges between 0.20 and 0.42%, followed by the index developed by Braathe (1980) which explains between 0.14 and 0.33% the effect of competition on growth in basal area (GI) and finally the lowest and therefore less reliable results were obtained Index of Daniels et., To 1989 which provided only between 0.11 and 0.18% to explain such relationship.…”

    Mathematical formulations and optimization algorithms for solving rich vehicle routing problems. por Palomo Martínez, Pamela Jocelyn

    Publicado 2018
    “…Computational results over small-sized instances show that the heuristic is competitive with the ǫ-constraint method. Also, computational tests over large-sized instances were carried out in order to study how the characteristics of the instances impact the algorithm performance. …”

    Clonación y expresión del ADNc que codifica para la enzima endo-β-1,4-glucanasa de Coptotermes formosanus en Pichia pastoris por Jara Ochoa, Javier Omar

    Publicado 2017
    “…Recombinant cellulases could be useful in a bioethanol production program based on sugar, it could also have another applications such as the treatment of products in fermentation industry; besides provide extra information that could facilitate cellulolytic understanding in termites and therefore to the development of biopesticides.…”

    Aislamiento y caracterización de un inmunógeno asociado al linfoma L5178Y por Caballero Hernández, Diana Elia

    Publicado 2008
    “…Through this approach it was detected an immunogenic form of alpha-2-HSglycoprotein, also known as fetuin-A, on LY-R lymphoma cells. Fetuin-A was recognized by antibodies present in the serum of LY-R tumor-bearing and immunized mice, but not by sera of mice immunized with the non-tumorigenic variant LY-S or by healthy mouse serum. …”

    Diversidad de especies arbóreas y arbustivas en áreas con distinto historial antropogénico en el matorral espinoso tamaulipeco por Alanís Rodríguez, Eduardo

    Publicado 2006
    “…Results were different for different land use histories, given that species composition was also different. Jaccard and Sorensen Similarity indices showed that the community formerly used for intensive grazing was the most different from other land use histories. …”
