    Variações composicionais de olivinas do complexo alcalino-carbonatítico de Salitre, MG
    (2012-12) Barbosa, Elisa Soares Rocha; Brod, José Affonso; Cordeiro, Pedro Filipe de Oliveira; Brod, Tereza Cristina Junqueira
    Compositional variation of olivines from Salitre alkaline-carbonatite complex, MG. The Salitre alkaline-carbonatite-phoscorite complex belongs to the Alto Paranaíba Igneous Province and consists of three separate bodies. Salitre I is a central, kidney-shaped body composed dominantly of bebedourites, with swarms of ring dykes of carbonatites and phoscorites; Salitre II and III are bebedourite-dominated smaller intrusions, respectively to the north and to the south of Salitre I. Olivine occurs in bebedourites, phoscorites and carbonatites, with forsterite content ranging from 83 to 98 mol. %. The least evolved rocks (bebedourites) show lower forsterite content than the more evolved members (phoscorites and carbonatittes), and olivine from carbonatites have the highest forsterite content. The compositional range of forsterite content observed in bebedourites is related to crystal fractionation. In phoscorites, forsterite content increases with decreasing whole-rock MgO, and in carbonatites it decreases, with the decreasing whole-rock MgO. Variations in CaO and MnO may occur in Salitre olivines. The controls of their distribution are unclear and may suggest local variations in the concentration of these elements in the magma, rather than a crystallographic control of olivine. NiO contents show differences between olivines from bebedourites, and olivines from phoscorites and carbonatites. This discrepancy may be related to the removal of Ni from the system by early fractionation of Ni-rich olivine from a silicate parental magma or, alternatively, by Ni removal in an immiscible sulfide liquid.

    Análise do tema economia solidária nas produções dos programas de pós-graduação em Geografia
    (2015-07) Severino, Maico Roris; Barbosa, Janete Costa Ribeiro; Ribeiro, Marina Pires
    The Solidarity Economy experiences have grown exponentially in Brazil since the start of the 21st century. To that extent, the various areas of knowledge have been developing studies to better understand this phenomenon, among them, Geography. The purpose of this paper is, therefore, to perform a quantitative and qualitative analysis of graduate programs productions (theses and dissertations) on geography and the solidarity economy topic. Hence, a literature review was conducted in order to gather all theses and dissertations up to the year of 2014, that addressed the topic. It was perceived that the geography research on the topic is still limited and regionally concentrated, but on the other hand, the studies analyzed show interesting analysis and broad scopes. The main contribution of this paper is the diagnosis of how the solidarity economy theme has been studied in geography, as well as to point out other research opportunities.

    Guidelines to devise a multimodal freight transportation network in developing regions under economic growth approach
    (2014-12) Almeida, Cristiano Farias; Gularte, Juliana Gomes; Yamashita, Yaeko
    In Brazil, especially at the Amazon Region, the relationship between transport and economic development has been studied since 70s with elaboration of several plans. However, due to many factors, such as the incompatibility between the proposed models of transport planning and territorial planning, the expected results were not reached. Under these aspects, the goal of this paper is to define guidelines in order to devise a multimodal freight transportation network that allows efficient transport of products in a developing region. This network was developed using natural resources and it stimulates the economic growth and development based on the Growth and Development Poles Theory and Graphs Theory. As result three networks related to three different scenarios – status quo, investment in transport infrastructure by the governmental programs, and the strategy scenario – have been elaborated and analyzed considering the operational transport costs and their spatial configuration.

    Identification of development poles on Brazilian Amazon region and analysis of the geographic accessibility
    (2020-10) Santos, Alex Mota dos; Almeida, Cristiano Farias; Soares, Daniel de Oliveira; Silva, Carlos Fabricio Assunção da
    Identification of development poles within the regional planning is important for defining the nodes of a given transport network and plays the role of driving economic growth in a region. Nevertheless, such proceedings are complex, especially in some areas where there is a lack of data that could support studies of this nature, for example in the case of the Amazon region. Thus, this study aims to identify development poles using spatial analysis of production values of soya, coffee, wood, and mineral products like cassiterite, aluminum ore, iron ore and copper. In addition, the geographic accessibility analysis was carried out at these poles in order to identify the potential of the transport network to be structured. Results demonstrated that it is possible to build a dense transport network by identifying more development poles, which would increase the connectivity, allowing more intense exchange of flows and development of the region.

    Exploring the relationship between transportation infrastructure and regional economic growth using Losch’s location theory
    (2021-05-14) Almeida, Cristiano Farias; Silva, Francisco Gildemir Ferreira da; Araujo, Paulo Henrique Cirino
    There are some knowledge gaps regarding the relationship between transportation infrastructure and economic development, especially about economic impacts that occur due to implementation of infrastructure in a given region, albeit various studies have addressed the issue. This paper aims to identify variables that affect economic development in order to contribute to the development of a theoretical model that could explain the relationship between transportation infrastructure and economic development. The theoretical model is satisfactory because it begins by analyzing the actions generated by the transportation infrastructure. Moreover, the model is based on the Location Theory considering the economic development and taking into account variables such as transportation costs, gain, product value, consumption, competition between companies and lastly monopoly. Finally, an econometric procedure, Spatial Panel Auto Regressive Vector Model (PVAR), was used to evaluate the relationship between economic development and investments in transportation infrastructure.

    (2017-12) Perim, Thiago Marcell Pires; Caetano, Mauro; Costa, Sérgio Henrique Barroca; Pimenta, Daiana Paula; Almeida, Cristiano Farias
    Understanding the elements that potentiate the economic development of a certain locality becomes necessary in the managerial sciences and planning of touristic destinations. Collaborating with theoretical gaps related to the particular analysis of transport activities and their impact on tourism, this study seeks to identify the economic relations between tourism and road transportation of people in tourist cities, being adopted as a reference the case of Caldas Novas / Goiás / Brazil, one of the main tourist destinations in the country. From the use of economic data and the characteristic of people transportation, statistical models has been used to analyze, for example, the impact of the increase of vehicles to public transport at the gross domestic product of the municipality, demonstrating the levels of impact between the variables considered. Such results can be used to manage the transport activities and for the planning of tourism.

    Metodologia para avaliação de rotas cicloviárias sob o enfoque da psicologia ambiental
    (2021-12) Almeida, Cristiano Farias; Hamer, Luciana Joyce; Cools, Mario
    This study aimed to develop a methodology for evaluation of cycle routes through indicators and based on Environmental Psychology and the physical characteristics of the urban space. For the study of the people behavior in the urban environment, the legibility and apprehension parameters of the "place" were adopted in addition to the foundations presented by Environmental Psychology: personal space, territoriality, privacy and density/crowding in its relation with cycling. The variables presented were measured through the Hierarchical Analysis in order to evaluate the Via Condition Index, which enabled the definition of a more efficient segment in a road network1 to compose the cycling system. The methodology is composed of the following steps: area delimitation, characterization of the area of study, identification of the segments with greater potential for trips with bicycles, evaluation of the condition index of the route, analysis of intervention opportunities and choice of the stretch of implementation. A case study was carried out in the city of Goiânia in order to validate the presented methodology. Thus, it is intended to assist managers and professionals in decision making regarding the implementation of cycle routes within a behavioral perspective.
