The objective of this research was to determine the relationship between inefficiency furrow irrigation, geometric characteristics agricultural plots and depletion aquifer conditions Laguna Bustillos basin (Chihuahua, Mexico) in recent decades (1991-2012). main results were: a) analysis showed that Mennonite properties have least favorable for use irrigation; b) index irrigation demonstrated existence exceed 2.5 13 times maximum allowed length; c) spatial temporal evolution areas with higher...
This work compares the landscapes built by Mennonites and Mestizos of Chihuahua, Mexico. comparison was made through characterization land cover use, obtaining landscape ecology metrics in plots both social groups. The results show that have more intensive agricultural landscapes, a process organization appropriation space linked to their history religion. These findings help understand evolution cultural Mexico elsewhere Latin America, where there are colonies Mennonite population, or...
This paper analyzed the temporal and spatial evolution of vegetation dynamics in various land covers basin Laguna Bustillos, Region Cuauhtémoc, Chihuahua, Mexico. We used an NDVI time series for months March to April (early spring). The was constructed from Landsat TM images period 1986-2011. results show increase vegetated areas, especially conifer cover, while shrub grassland showed a positive trend but with lower statistical significance. minimum temperatures early spring, during study...
The objectives of this work were to identify areas in probability being deforested the west Chihuahua, Mexico, and their causal variables, using a logistic regression model. was developed Geographic Information System, through deployment statistical between ten layers geographic information (biophysical socioeconomic) related deforestation four municipalities state during period 2007-2013. results indicate good predictive power technique (McFadden's Pseudo-R2 0.26), degree marginalization,...
Actualmente la exploración espacial está convirtiéndose en una actividad cada vez más importante desde que permiten aumentar el conocimiento cuanto a formación de planetas, actividades económicas (minería espacial) así como un mejor entendimiento fenómenos geológicos y biológicos permitan futuro creación hábitats humanos fuera del planeta Tierra. En este sentido, uno los principales problemas asociado al aterrizaje seguro las sondas espaciales. A partir lo anterior presente artículo propone...
Introduction: Triatoma recurva is a Trypanosoma cruzi vector whose distribution and biological development are determined by factors that may influence the transmission of trypanosomiasis to humans.Objective: To identify potential spatial recurve, as well social determining its presence.Materials methods: We used MaxEnt software construct ecological niche models while bioclimatic variables (WorldClim) were derived from monthly values temperature precipitation generate biologically...
The study of bending behaviour thin-walled structures has gained importance since lateral impact is the second most common scenario in automobile crashes. current paper analyses an effect partition plates on energy absorption (E a ) circular profiles under loads. For this purpose, several numerical using Abaqus/Explicit finite element software were carried out. evaluated specimens have cross-sections reinforced by different arrangement plates. In order to get reliable outcome, special...
The current paper analyzes the effect of cross-section on energy absorption capabilities sandwich structures under compressive loads. For this purpose, several including triangular, square, hexagonal and circular shapes were analyzed using Abaqus software. According to results shape is most favorable increase crashworthiness performance up 700% CFE with respect square arrangement.
Cuando un choque automotriz ocurre, la energía de impacto se transfiere a los pasajeros lo cual provoca lesiones graves y decesos. Con el objeto analizar efecto las cargas dinámicas en cuerpo humano, uso maniquíes está incremento. Sin embargo, su costo es demasiado alto, así como accesibilidad. Por tanto, presente artículo propone diseño desarrollo modelo discreto que representa cabeza cuello maniquí para pruebas utilizando software elemento finito Abaqus. El conformado por cabeza, región...
Actualmente la aplicación de patrones biológicos dentro del diseño sistemas mecánicos está en incremento debido a su éxito evolutivo. En este sentido tras millones años evolución naturaleza ha proveído estructuras optimizadas los seres vivos para asegurar supervivencia ante cambios climáticos o depredadores. A partir lo anterior el presente artículo describe y evaluación numérica tipo panal abeja basadas caparazón un armadillo. Las fueron construidas con aluminio 6063-T5 evaluadas través...
In this paper finite element software Abaqus was used to analyse the effect of cross-sectional shape on crashworthiness performance multi-cell profiles. An emphasis placed modelling damage initiation criteria and its evolution during crash event. The structures evaluated included square circular cross-sections fabricated with aluminium alloy EN AW-7108 T6. During simulations, were subjected axial impact loads using a 500-kg rigid body striker an initial velocity 10 m/s. Accordingly our...
