The metropolitan region of São Paulo is the most populous of the country, this happens because of its great importance in the national economy and the job opportunities that are offered to the population. These factors result in intense population growth and urban expansion, reaching some non-habitable places of the metropolis, as areas of pipelines, which are very important for the transportation of natural gas, oil and its derivatives. Before the population growth of the region, these sites were unoccupied, do not presenting problems for the population. However, with the disorderly occupation is generated great anthropogenic pressure on the pipeline stitches, causing risks to people who are around them. Therefore it is extremely important to monitor the strip of pipelines through products and techniques of remote sensing and geoprocessing, enabling, through high spatial resolution images, identification of objects or phenomena that occur on Earth's surface that can alter the functioning and safety of pipelines. Therefore, this study aims to monitor a stretch of the area of the pipeline mesh GASPAL/OSVAT and Capuava Refinery (RECAP), located on the outskirts of the metropolitan area of São Paulo in the city of Mauá, who suffer great human pressure, proving thus the techniques of remote sensing and geographic information system (GIS) as effective tools for monitoring phenomena occurred in urban areas of great complexity. The monitoring was done by object-based classification applied in orbital images Ikonos II and RapidEye, of high spatial resolution and, image processing, detection of objects, segmentation, classification and editing were developed through the eCognition and ArcGis softwares. To determine the statistical accuracy of the mapping of the land cover of the stretch of pipeline in Maua, the results were analyzed by error matrix...

A consequence of population growth is the increased generation of solid waste, which requires environmentally and economically viable suitable disposal sites. The scarcity of such sites makes necessary to adopt non-generation measures, reduction, reuse , recycling and treatment of solid waste before final disposal of waste. This paper presents the quantification and qualification of organic waste generated in each sector of the University Restaurant (UR) , by proposing indicators of waste generation per meal (index of waste) . Then, from the characterization of the waste management practices adopted internally, evaluates the potential deployment of the composting process for organic waste, with signaling for opportunities to improve waste management. The diagnosis of waste generation was made based on data collected during the period of 10 days. The waste were classified into 3 groups (organic, recyclable and waste) in each sector of the restaurant ( pre preparation , kitchen and tray return) . The results reveal that 33 % of the waste generated in the UR currently has the potential to be composted in a suitable place on campus. Every meal served generat approximately 124g of waste, of which 35g are organic waste of the pre preparation sector, 49g are remnants of food in the tray’s return and 40g are other kinds of waste, including recyclable and non recyclable. You can still get a higher percentage of compostable if the trays pre-wash is not performed with detergent and water. To minimize the generation of waste trays can be replaced by plates and skimmers and ladles can be replaced by smaller ones. The food exposed in the counter but not consumed, can be distributed to students after the restaurant is closed so this material would not be disposed in the garbage

O ensino básico elementar e complementar é um elemento primordial para o desenvolvimento humano (aluno) e é a fonte da sabedoria e da ampliação do conhecimento científico. Para desenvolvimento e crescimento populacional de um país é fundamental o investimento, ou ampliação da rede educacional. A falta do número suficiente das escolas e professores nos últimos anos tem sido a maior preocupação dos alunos e também do Ministério da Educação Nacional em Bissau, mas com a falta das condições financeiras e da coordenadoria dos projetos educacionais o País acaba de abarcar tais situações. A procura do ensino básico elementar e complementar (liceu) no interior do País foi e ainda é até hoje, uma das causas do êxodo rural. Antigamente o enquadramento dos filhos dos agricultores na escola era visto para os pais como o abandono da família principalmente nos trabalhos domésticos e do campo/lavora; devido a falta das escolas eles são obrigados de abandonar regiões deles a fim de procurar as escolas, ou seja, escola que atende os seus níveis escolares, mas hoje em dia com mentalidade diferente em relação ao passado todas as pessoas querem adquirir ensino, ou seja, a formação educacional. Com as experiências vividas ao longo do período em Guiné-Bissau nos últimos anos, a rede de ensino não cresce proporcionalmente em relação ao crescimento populacional, muitas das vezes as suas ampliações sempre foram feitas através de uma forma provisória e desconfortável aos seus usuários. Então a idéia da criação de um novo complexo, ou projeto do Edifício Escolar para a República da Guiné-Bissau ajudará futuramente para o desenvolvimento do País, isto é, se for implantados em Bissau e multiplicados no interior da Guiné-Bissau. O objetivo deste Trabalho de Conclusão de Curso foi desenvolver o projeto... (Resumo completo, clicar acesso eletrônico abaixo)

According to data from the World Health Organization, the older population will grow sixteenfold from 1950 to 2025 in comparison to a fivefold population growth in the same period, which is referred to by UNO as the “Ageing Era”. This places Brazil in the sixth position in the contingent of older individuals worldwide, with a number that is higher than 32 million. Considering how topics such as quality of life and social vulnerability are important in face of the growing older population, these topics must be furthered studied so that they can be understood as important variables for both better clinical practice and scientific research. To describe the social vulnerability and evaluate the quality of life of older individuals in a population hospitalized in the internal medicine ward of Bauru State Hospital. This is a descriptive qualitative study that was conducted by means of interviews and using Bardin’s discourse analysis. The inclusion criteria used in this study were: individuals at 60 years of age who were mentally capable of answering the proposed questions. Two categories concerning Quality of Life and Social Vulnerability emerged from the interviews. The following emerged from the theme Quality of Life: “Life as something important” and subcategories that involved feeling useful in society, having a supportive family, independence, optimism and joy and survival. Also, the following emerged from the theme Social Vulnerability: “Negative recognition of older individuals in society” and subcategories that involved lack of respect, functional disability, family indifference, housing-related insecurity, an inefficient health care system and loneliness. Quality of Life and Social Vulnerability are largely discussed themes in the present scenario. In this study, it was possible to perceive that the older population needs social support, effective public... (Complete abstract click electronic access below)

Population growth, together with the gradual social ascent in Brazil, reflects at the growing need for better use of urban spaces. In this context, the amount of new buildings to meet the demand in property market, the needs for creating new roads and highways, among others, make the use of geotechnical works and, more specifically, retaining walls, more and more common. One of the simplest solutions for underground works is the use of retaining structures using tie back walls for soil support, therefore, the present work deals with this kind of structures. This paper proposes the use of FTOOL software testing in predicting deformations in tie back walls, by comparing simulations of the presented model to a real and measured deformation case in Guabirotuba Formation (PR). The results showed the importance of defining the parameters such as stiffness and curtain geometry, as well as the definition of representative loads acting on it. Also, it was pointed out that the passive response of the steel rods depends on the horizontal displacement of the wall. The study concluded that the program generates very representative results when compared to field data and seems to be a promising tool for tie back structures displacement predictions

The research shows that increasing the consumption of energy by households is growing rapidly and without adequate planning, due to population growth and therefore an increase in energy consumption. With the current concerns of sustainability and energy efficiency by industry, there is the need to prove to population that there are many ways to incorporate sustainable practices to their daily lives, starting from by their own residence. The quality certification of the energy efficiency level in residential buildings, shows how one can influence and improve housing issues on sustainable actions as rooted in our country

Mobility and accessibility are terms that are related to each other. Large urban centers now face problems arising from rapid population growth and among them are problems inherent to mobility and accessibility. The aim of this paper was to conduct a literature review, from a review in journals and books on the issue of mobility in urban centers, showing how mobility is associated with accessibility. A key finding was that the new social reality is the challenge for the future planning of cities and in these cases should be used the knowledge of design, architecture, urbanism and urban planning to address these problems.

The rising in greenhouse gases emission as consequence of industrial expansion especially in developing countries is appointed as one of those reasons responsible for global warming. High-level temperatures are set as responsible for low productivity and high levels of discomfort. With the increase of worldwide energy demand, due to the population growth, this work aims to be an introductory text revising the current ventilation (mechanical and natural) and refrigeration technologies as well as low energy cooling techniques and architectural alternatives that seeks offering good ventilation and ideal buildings temperatures, making them sustainable. In addition, the text deals with the measurement instruments used to evaluate the parameters defined by international and national standards. At last, a case of study applies few concepts and technologies described in the text, introducing the results achieved, the limitations and suggestions to future works
