title: LOWER CIRCUIT OF THE URBAN ECONOMY AND LOCAL CITIES-HYBRIDS

description: Abstract In the current period, marked by processes of globalization and fragmentation, endows fluidity space, science, technique, information and rationality, in which part, also, the increase of unemployment, the precariousness of labour relations and structural poverty. In this context, the theory of the two circuits of the urban economy further strengthens as a possibility of seizure of contemporary urban dynamics. In this sense, in this article we discuss the theory of circuits of urban economics to three local cities socio-spatial reality - hybrid-, located in the extreme west of the State of São Paulo - Brazil. Our analyses are, mainly, in the understanding of the dynamics of the lower circuit of the urban economy, the possibility of dialectical reading between both circuits and, in an analysis that includes the interurban division of labor. Finally, think of the urban economy lower circuit for socio-spatial reality of local cities - hybrids, allows us to understand the relation between poverty and lower circuit.

title: Mobility index for urban freight transportation

description: Abstract This paper proposes a mobility index for urban freight transportation (UFT), with the purpose of subsidizing decisions related to the implementation of actions and measures that may lead to improvements in the mobility level in a certain city area. Mobility indices have been priory proposed for assessing and monitoring the movement of people within city borders, but this topic has been understudied in the context urban freight transportation. Therefore, in order to develop a mobility index for UFT, we carried a literature review to identify the main actions that could be implemented by the government in order to mitigate externalities caused by urban freight transportation. Based on the result of this literature review, a set of indicators to compose an mobility index for freight transportation was proposed. We used the principle of aggregating indicators to formulate the proposed index and, to define the weight of each indicator, we opted to use a multicriteria decision aid method. The proposed index was applied in the city center of Niterói/RJ. The resulting value for the UFT mobility index, in this application, indicates that this area does not have a good mobility level for urban freight transportation, lacking implementing measures to reverse this situation.

title: Comparison between traditional project appraisal methods and uncertainty analysis applied to mining planning

description: Abstract Long-term mining planning is a complex process which involves a large number of variables and uncertainties. Traditional discount cash flow (DCF) is usually used in the evaluation of mining projects. DCF includes net present value (NPV), internal rate of return (IRR), and profitability index (PI). A sensitivity analysis is usually carried out to evaluate the impact of the main variables on the project. Another way to measure uncertainties is through the Monte Carlo simulation (MCS). The objective of this study is to evaluate and compare the DCF methods and measure uncertainties through sensitivity analysis and MCS in the evaluation of mine sequencing. A case study of a phosphate mine project was used to chart the comparative study. In the results, NPV and uncertainty analysis through MCS were more consistent.

title: Smart Cities: Insights and Contributions from Brazilian Research

description: Abstract The aim of this study was to identify the network of Brazilian researchers studying smart cities and describe their main contributions to the debate on the theme. Representation of relationship networks was carried out to obtain a photograph of the nuclei of research in "smart cities" and a systematic review of the literature of the existing national productions. The results show that there is a conceptual and empirical predominance of smart cities that bring together aspects related to Information and Communication Technology and people's quality of life, connecting them and enabling them in order to promote constant interactions in cities and public governance . Researchers who study the subject are located mainly at USP, PUC Campinas, UFPE and UNINOVE, however, networks of relations between universities in the conduction of the research were not evidenced. The article assists in the general analysis of the research carried out in Brazil on intelligent cities as well as contributes to the discussion of the need for a broader view of the concept of intelligent cities, which goes beyond the creation of ICTs evidenced in this study.

title: WINTER COVER CROPS ON WEED INFESTATION AND MAIZE YIELD

description: ABSTRACT The establishment of commercial crops in succession to winter cover crops that leaves a dense straw layer provides significantly suppression of weeds. The objective of this work was to evaluate the suppressive potential of winter cover crops on weed infestation in maize and its effect on the yield of the maize sown in succession. The experiment was conducted in the 2012/2013 crop season, in an area of the UFSM Campus Frederico Westphalen, State of Rio Grande do Sul. Four different species of cover crops (black oat, ryegrass, vetch and forage radish) were seeded and a fallow area was used as control. Evaluations to quantify the dry matter and chemical desiccation were performed at the full flowering period of the cover crops. Maize was sown in no-tillage system, in succession to the cover crops. The incidence and shoot dry matter of weeds (g 0.25 m-2) was evaluated 15 days after the maize emergence. The main weed species in the area were: morning-glory (Ipomoea grandifolia), wild poinsettia (Euphorbia heterophylla), large crabgrass (Digitaria sanguinalis) and purple nutsedge (Cyperus rotundus). In general, vetch and ryegrass were the winter cover crops that better suppressed the weeds evaluated. The best maize yield was found in the area previously covered with ryegrass, inferring a relation between the cover crop and suppression of weeds and crop yield.

title: Assessment of efficiency in privatized airports

description: Abstract Since the mid-1990s, and in several temporary phases, the main Colombian airports have been privatized. Based on this, it is of great interest to know, analyze and even measure the technical efficiency of airports in a context of structural reform, that is, to evaluate the influence of the privatization of airports on efficiency and a relationship ''before-after''. The methodology used to carry out the study is the Data Envelopment Analysis (DEA). This methodology is used to estimate the relative efficiency of 16 airports (now privatized) in Colombia and at a comparative level, that is, in three specific consecutive scenarios: public management, transition, private management. The methodology uses typical ''technical variables'' (used in similar investigations). The main results of the research reveal much higher global efficiency rates when the management of airports is completely private (that is, carried out 100% by a private operator) with respect to when they were managed by the public sector.

title: DRY FOREST DEFORESTATION DYNAMICS IN BRAZIL’S PONTAL BASIN

description: ABSTRACT Reliable information on vegetation cover and its dynamics over time is essential for managing life, resources, and supporting policies. Although many related initiatives have been undertaken in Brazil since the 1980s, knowledge about its dry forests is still limited. In this study, we address the drivers of deforestation and their threat to the Brazilian dry forest called Caatinga. We evaluated the land cover dynamics and landscape metrics in the watershed of the Pontal River, as it has become one of the most socially and environmentally important areas in Brazil. The overall process consists of a systematic sampling grid of hydrological samples, where Landsat images (1975 to 2013) combined with the FRAGSTATS package were used to evaluate landscape metrics indices for the Caatinga. Data showed that the relative area (RA) decreased from 90.25% to 60.98% over the 38-year period, while fragmentation (PD) presented an increasing bias. In addition, the spatial distribution of both indices became more heterogeneous and clustered in the north. We suggest that appropriateness of land for farming was the leading cause of deforestation; rainfall is 112% more intense in the north of the watershed than in the south. Therefore, the northern fauna and flora have been significantly altered and reduced. The relationship between deforestation and time shows an increasing threat. Further studies evaluating these causes are needed to improve our understanding of the vegetation dynamics in this region.

title: Physiological quality and expression of genes in seeds of Handroanthus serratifolius subjected to drying

description: Handroanthus serratifolius seeds are considered orthodox and have some mechanisms that assist in desiccation tolerance, like heat-resistant proteins and the presence of protective systems against free radical production. In order to investigate the drying effect on the quality of Handroanthus serratifolius seeds collected with 28% water content two methods were used: slow drying (30 °C) and fast drying (45 °C) until water contents equaled 20%, 15%, 10% and 5%. Seed quality was assessed by germination test, first count of germination, speed germination, emergence and speed emergence. The expression of heat-resistant proteins and enzymes catalase, esterase and isocitrate lyase was assessed by electrophoresis. The gene expression of sHSP17.5, CAT3 and ICL6 was quantified by real time PCR. Higher values of germination and vigor were obtained in seeds with 20% water content, subjected to fast drying. There was induction of heat-resistant proteins expression for both drying methods. There was variation in the electrophoretic pattern of catalase, esterase and isocitrate lyase in seeds subjected to different treatments. The gene expression in Handroanthus serratifolius seeds varies depending on methods of drying and water content of seeds. The drying of Handroanthus serratifolius seeds until the water content between 15 and 10% compromises their physiological quality.

title: Identification of sources of solid waste generation in a food and nutrition unit

description: Collective food service is considered a major source of food waste. In order to acquire detailed data of food loss and waste generation in this sector, the waste of one Food and Nutrition Unit (FNU) was classified into categories: inventory losses and storage losses in food processing, distribution and return. The study sought to identify and quantify the waste generated over five days at a FNU located inside an automobile parts manufacturing shop in the city of Taubaté, SP, and we proposed an action plan to reduce the environmental impact based upon the three r's principle. In order to serve 2,740 meals, 486.6 kg of solid waste were generated, resulting in an average per capita of 0.177 kg / day of waste. The waste was distributed as follows: 58.0% in food processing, 31.9% in returns and 10.1% in stock and storage. Of the total solid waste, 85% was organic compounds of unwanted portions of vegetables and meat, food scraps, leftovers from dinners, expired food and food samples, and 15% was composed of waste paper/cardboard, plastics and cans. The largest waste generation was due to the disposal of inedible food, food scraps produced and rest-intake, these results are related to waste food, 100% intended for composting. As for the other waste, 80% was destined for recycling and 20% was taken to the landfill.

title: Access to breast cancer care in a municipality in Bahia: the perspective of users, workers and managers

description: ABSTRACT This study aimed to evaluate the access of women with breast cancer to health care services in a medium-sized municipality in the interior of Bahia, from the perspective of users, workers and managers. This is a case study with a qualitative approach, carried out with women diagnosed with breast cancer, both in urban and rural areas. In addition, primary health care workers of medium and high complexity and municipal managers participated. The results were presented in two categories: Organization of the breast cancer care network and Access to breast cancer care in the health care network. In the first, the lack of a line of care for breast cancer stands out, insufficient health financing and fragility in the mechanisms of integration of the care network. In the second, ineffective mammographic screening, focusing on breast cancer care in the Pink October and difficulty accessing the exams and specialized procedures, such as consultation with a mastologist and breast puncture/biopsy. The plurality of evaluated perspectives allowed observing important gaps in the constitution of the care network for women with breast cancer, in which organizational problems feedback with those related to the care provided.

title: Selection of priority areas for payment of environmental services: an analysis at the watershed level

description: Abstract In this study, we selected priority areas for conservation of water resources to support programs for environmental services (PSA) payment. The proposal will be used for the implementation of the PSA pilot project in the watershed of the Murundu, Ibiúna-SP, to support PSA public policy to foster sustainability. To do so, land use information layers, vegetative cover and slope were organized in a GIS environment in order to allow through cross tabulation the selection of priorities to generate a thematic map. From this map, we performed qualitative and a quantitative analysis, as well as priority setting ranges. The tools used have shown to be useful in supporting decision-making and research and public policy in PSA, focusing on increasing the governance of water resources. It is clear that remuneration for "standing forest" definitely represents the major prospect in the watershed of the river's Murundu, as well as the possibility of converting monetary values of the payment into other forms of support to providers of the service according to their priorities.

title: Inequalities as sources of urban dynamics in the historic center of Lisbon

description: In the 1980s, the historic center of Lisbon became a major challenge for local public actors who have tried to make it the window of the capital city and one of the drivers of the urban dynamics. Unlike what was described by the Anglo-Saxons in the 1960s, socio-spatial gentrification never appears as a goal. Instead, public policies clearly seek to maintain and help the long-established population in the historic neighborhoods of the capital city. This effort is reflected in the statistics or in the persistent inequalities observed in the territory. Far from being a handicap, it seems that these policies are a driving force of the urban dynamics in the old city center.

title: Territory as an urban mediation technology: the territorial customization of apps

description: Abstract Information and communication technologies have changed the context in which we live on the most varied scales. For this reason, they have also become an important management tool for the problems of contemporary cities. This article aims to investigate the relationship between territory and technology, noting that technology is a producer of territories, but not all territory produces the same technology. This relationship will be explained by the analysis of the territorial customization of the mobile applications AlertaBlu (Blumenau/SC) and Onde Tem Tiroteio (Rio de Janeiro/RJ). The methodology consists of a bibliographic review and comparative analysis. The results show that these applications are territorial creators because they demarcate the safe and insecure places of the cities where they work. We conclude that these territories function as an urban mediation tool.

title: Image segmentation and particles classification using texture analysis method

description: Introduction: Ingredients of oily fish include a large amount of polyunsaturated fatty acids, which are important elements in various metabolic processes of humans, and have also been used to prevent diseases. However, in an attempt to reduce cost, recent developments are starting a replace the ingredients of fish oil with products of microalgae, that also produce polyunsaturated fatty acids. To do so, it is important to closely monitor morphological changes in algae cells and monitor their age in order to achieve the best results. This paper aims to describe an advanced vision-based system to automatically detect, classify, and track the organic cells using a recently developed SOPAT-System (Smart On-line Particle Analysis Technology), a photo-optical image acquisition device combined with innovative image analysis software. Methods The proposed method includes image de-noising, binarization and Enhancement, as well as object recognition, localization and classification based on the analysis of particles’ size and texture. Results The methods allowed for correctly computing cell’s size for each particle separately. By computing an area histogram for the input images (1h, 18h, and 42h), the variation could be observed showing a clear increase in cell. Conclusion The proposed method allows for algae particles to be correctly identified with accuracies up to 99% and classified correctly with accuracies up to 100%.
