Conformación geo-histórica de las actividades económicas en el Estado de Guerrero, México

NEFTALI GARCIA CASTRO (2018)

This research synthesizes a series of geo-historical events around the economic-productive configuration of the state of Guerrero. This document presents the following: 1) the sequence that must be followed to prepare a matrix with the relevant events for an analysis from the geo-historical point of view; 2) at the same time, the document addresses the fundamental reasons that support the selection of this approach and the methodological solution proposed; and 3) it shows the historical stages based on the preponderant economic form of occupation of the territory of Guerrero

Productive response of creole lambs fed integral diets with Samanea saman (Jacq.) Merr. pods.

JERONIMO HERRERA PEREZ ULISES CARBAJAL MARQUEZ NICOLAS TORRES SALADO PAULINO SANCHEZ SANTILLAN OMAR RAMIREZ REYNOSO ADELAIDO RAFAEL ROJAS GARCIA MARCO ANTONIO AYALA MONTER (2021)

Objective: To evaluate the productive variables and the digestibility of the nutrients of an integral diet for lambs with

increasing inclusion of Samanea saman pods. Design/methodology/approach: 24 creole lambs (initial weight of 20.6¿0.3 kg) distributed in a completely randomized experimental design were used. The treatments were: T1, 0%, T2, 12.5%, and T3, 25% of Samanea saman pod inclusion. The productive variables and the digestibility of the nutrients were evaluated and compared with the Tukey test (¿¿0.05); meanwhile, the response to the increasing content of Samanea saman was evaluated by orthogonal contrasts. The variables dry matter intake (DMI), daily weight gain (DWG) and feed conversion (FC) showed no differences (p¿0.05)between treatments.

Áreas potenciales para plantaciones de Agave angustifolia Haw en Guerrero, México.

JORGE HUERTA ZAVALA JUAN ELIAS SABINO LOPEZ AGUSTIN DAMIAN NAVA HECTOR RAMON SEGURA PACHECO ELIAS HERNANDEZ CASTRO (2019)

Objective: To determine optimum and suboptimal areas for the establishment of plantations of Agave angustifolia Haw,

in Guerrero, Mexico. Design/methodology/approach: A collection of 139 specimens of A. angustifolia was carried out, obtaining for each specimen phenotypic, agroclimatic and agroecological data. The information of 30 specimens of herbarium was consulted. Interviews were conducted with the representatives of the state council of mezcal in Guerrero, the company Sanzekan Tinemi and Mezcalli del Sur, to complement the information of the areas. A database was created where the information of each copy was included, as well as the information obtained from the interviews. Criteria for selecting potential areas of A. angustifolia were defined, after which a Geographic Information Systems (GIS) was constructed, generating mapping areas with agroclimatic and agro potential, wherein the optimal suboptimal and marginal areas for the establishment of A.

A Classroom Experience: Vector Concept.

Viana Nallely Garcia Salmeron FLOR MONSERRAT RODRIGUEZ VASQUEZ (2020)

According to several studies, working with vectors is a problem for students from different educational levels. In this document we propose a Planeacion Didáctica Argumentada (PDA) to address the vector concept at lower secondary school level, emphasizing its features (magnitude, direction and sense) such that, it facilitates the formalization of the mentioned concept in a mathematical context. After implementing the PDA, we evidence that with the right instruction,

students can develop skills to work with vectors. After analyzing the results, is possible to establish some aspects that must be considered while teaching vectors, for example: the aspects of the teacher, students, curriculums and the previous physics and math necessary contents.
