6墨西哥城环境文化中心显示文摘“环境文化中心”作为墨西哥城Bosquede Chapultepec第二部分的全新文化、景观和环境节点,是由Gabriel Orozco操刀的“查普特佩克自然与文化”总体规划的一部分。该项目方案在墨西哥城政府与联邦政府共同举办的公开竞赛中脱颖而出,得以落成。环境文化中心是一座被植物花园包围的展馆,展现出自然主义设计与民族植物学相结合的理念。设计参考了墨西哥盆地山谷的多样化生态系统和自然景观,包括温带森林、草原、湿地和植被等,并与查普特佩克现有的植被、地形和设施进行细致整合,由此最大化地增加环境文化中心作为城市森林的巨大潜力。Rafael Ponce Ortiz Margarita Gorbea Angeles Cesar Avila OscarDiaz Gaspar Abigail Esparza Diego Buenode la Paz Valerio Lopez Acevedo Margarita Gorbea(摄影) Marcos Betanzos(摄影) 范嘉苑(编译) 2023现代装饰2023,,4:0

8Optimization of the Design of Structures in Coverage Using the Genetic Algorithm Method显示文摘In this research work,an optimization of the design of steel structures is developed through Genetic Algorithms(Gas)with the objective of reducing the amount of material and with them the cost,for which the programming of the GAs tool in the Fortran programming language with the SAP2000 Application Programming Interface(API)v.19 using Visual Studio Professional 2015-Intel?Visual Fortran with Parallel Studio XE.The GAs method consists of randomly searching the Objective Function(OF)of the optimal variables with restrictions.The OF defined by the weight of the structure,the variables in relation to the cross sections of the structural elements and the constraints are the design of resistance using the method of Load and Resistance Factor Design(LRFD),restriction of displacements and restriction of the ratio of slenderness considered in the National Building Regulations(RNE),whose GAs search parameters are given by probability of crossing 70%by simple crossing strategy,probability of mutation 20%,elitism of 5%and maximum number of generations according to the profile.The examined metal structure is a cover with five double-body warren arches with 32 m light connected with 24 joists both with welded connections,that is,rigid.The metal structure was evaluated on demand for loads(dead load,live load,snow load,wind load and earthquake loads).The structural design was carried out with the following profiles:circular,tubular,square,angular and Normal Profile with I-shaped section(IPN)of which the most optimal was the tubular profile.The outer diameters of the cross section are:diagonal with a diameter of 1 in,lower flange with a diameter of 23/8 in,upper flange with a diameter of 11/2 in,inner belt with a diameter of 1 in and belt.outside with a diameter of 11/2 in.Marco Lopez Barrantes Ivan Ayala Bizarro Kevin Escobar Curasma Rocky Ayala Bizarro Pedro Palomino Pastrana Cesar Jurado Mancha 2019Journal of Environmental Science and Engineering(A)2019,8,5:0

10Assessment of the Sensitivity of Soil Parameters in Sediment Production in the Ichu River Experimental Basin显示文摘This research aims to determine how much is the sensitivity of soil parameters in the production of sediments through the model distributed at the level of cells in the Ichu River Basin,which is located in the Andes of Peru,with an approximate surface area of 1,380.17 km2,corresponding to the control section and tributary to the Mantaro River.Also,for the evaluation of sensitivity determine the amount of sediments of the textures:silt,clay and sand.To achieve the objectives that have been raised in this research has been used the conceptual distributed hydrological model TETIS v9.1,which has been calibrated and validated using the climatic variables that are recorded at the hourly level in six weather stations and a hydrometric station,synthetic precipitation was also used withsatellite stations(CHIRPS)of the Climate Hazards Group that has registered with a grid of 0.05 degrees of resolution,from 1981 to the present.To determine the solid component,the TETIS v9.1 model uses the equations developed in the CASCade 2 Dimensional SEDimentation model(CASC2D-SED)that presents conceptual approaches with physical basis.The sediment processes on slopes this CASC2D-SED model simulates in two dimensions,as well as helps to determine the quantification of sediments at any point in the basin considering all physical processes.On the other hand,the OpenLandMap data portal has been used for land cover data of the K factor corresponding to the susceptibility of the soil that can suffer losses due to erosion.Also,the Moderate Resolution Imaging Spectroradiometer(MODIS)observation system to determine the Normalized Difference Vegetation Indices(NDVI)for the culture factor C.The parameter P corresponding to the conservation technique applied,has been developed using remote sensing techniques using the Google Earth Engine(GEE)platform.Finally,the results obtained from the evaluation of the sensitivity of the parameters are significant,in this way the hypothesis that is raised is approved.Ivan A.Ayala Bizarro Yunior AHuaman Paitan Marco Lopez Barrantes Jorge Ortega Vargas Omar Caballero sanchez Abdon Olivera Quintanilla Cesar Jurado Mancha Jessica Zuniga Mendoza Cesar Lifonzo Salcedo 2023Journal of Environmental Science and Engineering(A)2023,12,1:0
11Assessing stakeholders'perceptions and values towards social-ecological systems using participatory methods显示文摘Introduction:Many conservation initiatives for managing social-ecological landscapes factor in the best available biophysical information.However,insufficient consideration of social aspects can render such initiatives ineffective.By incorporating stakeholders'perceptions and values,and by involving stakeholders(transparently)in decision-making processes,conservation plans and efforts can better achieve desired goals and targets.Results:In this paper,we present and analyze three case studies within different ecological and land use contexts.Each case study uses different participatory approaches to elicit stakeholders'perceptions and values,while seeking to involve stakeholders in the decision-making process.The case studies are the following:(1)participatory scenario planning for a protected area in Doñana coastal wetland in Southwestern Spain;(2)assessment of ecosystem services trade-offs and social responses on rewards for agro-biodiversity in the rubber agroforest landscape in Jambi,Indonesia;and(3)socio-cultural evaluation,through visual stimuli,of ecosystem services provided by transhumance cultural landscapes in Central Spain.We discuss how stakeholders perceive and value their environments and to what extent participatory approaches are useful for capturing information relating to land use and ecological processes.Conclusions:Social-ecological systems are inherently complex,having a variety of interacting actors with different types of ecological knowledge,interests,and values.Different participatory tools or approaches are appropriate for various and specific contexts and objectives.Determining and integrating the various types of knowledge and values of different actors can contribute to a more comprehensive understanding of social-ecological systems.Grace B Villamor Ignacio Palomo Cesar A Lopez Santiago Elisa Oteros-Rozas Joe Hill 2014Ecological Processes2014,3,1:0
