One of the greatest problems nowadays is the correct management of solid waste produce in every human activity. On 2010, the “Política Nacional de Resíduos Sólidos” was approved, this law brings directives and instruments to deal with the solid waste issue. The objective of this work is to make a Strategic Assessment on a Solid Waste Management Plan applied to a medium size city. Based on general data about the situation of the solid wastes in Brazil, a first scenario was described. After that, likely scenarios were proposed, taking segregation, treatment and final disposal on account. Finally, those scenarios were compared, mainly in the final volume disposed and costs involved

Este trabalho tem como objetivos principais identificar se a prática da atividade física produz uma sensação de bem-estar; analisar os elementos psicofisiológicos que conduzam a esta sensação de bem-estar e verificar a existência de indicadores psicofisiológicos que apontem uma dosagem ideal para a prática saudável de atividade física para a dita sensação de bem-estar. Este tema foi escolhido, pois não existem muitos estudos com resultados concretos nesta área e a preocupação com o bem-estar e com a saúde tem sido cada dia mais freqüente graças ao aumento de doenças e sintomas do stress, depressão, dentre outros. Na literatura encontramos muitos autores e estudos que se preocupam em abordar tanto o tema de atividade física quanto o de bem-estar, mas quando juntamos estes dois assuntos os estudos ficam mais difíceis de ser encontrados, o que nos motiva a abordar estes dois temas em conjunto. (PROCEDIMENTOS METODOLÓGICOS) Pesquisa qualiquantitativa, com uso de instrumento do tipo questionário, sendo 11 perguntas abertas, além de 5 perguntas com o caráter de identificação. O público foi composto por 30 pessoas da cidade de Rio Claro/SP com idades entre 17 e 29 anos, sendo 11 do sexo masculino e 19 do sexo feminino; 28 estavam cursando o ensino superior, enquanto 2 já haviam completado o ensino superior e estavam fazendo pós-graduação. Os dados serão analisados através de categorização e os resultados deverão ser publicados em artigos ou similares.

Health Care Waste (HCW) represents 1%, and it has presently gained a lot of importance. Adequate management is one of the great challenges to be faced by health care centers. It has gained distinction and been widely discussed by members of the sectors involved with sanitation, public health and environmental issues due to waste physical, chemical biological characteristics, which pose potential risk to the environment and public health. The present study aims at evaluating HCW internal management by following all its phases, determining indicators, classifying and quantifying, establishing production rates (kg /patient/day) for the sector and designing materials to disseminate appropriate HCW disposal in the Emergency Room of the UNESP University Hospital in the city of Botucatu according to the guidelines presently in force. : From June to October 2011, the waste flow was observed from its production to final disposal. Four weight measurements were performed on four consecutive days in the month of August by using a properly calibrated (in grams) digital scale at the times scheduled for collection of the produced waste. Hence, the daily and monthly amounts were estimated according to their classification. All the waste packaged in the bags in garbage cans in the Emergency Room for a 24-hour period was considered to be a sample. Separation was not adequately performed in that sector, and waste from Group A was mixed with that from Group D. The amount of infectious waste produced in the sector corresponded to 87.80 %, common waste to 10.93 % and recyclable waste to 1.27%. The mean daily HCW production was of 123.300 kg/day, and the total monthly production was of 3,822 kg/month, which was distributed as follows: Group A 3,355,750 kg/month; Group D 417,570 kg/month and recyclables 48,670 kg/month. The production rate corresponded to 0.47 kg/patient/day, thus showing... (Complete abstract click electronic access below)

The problem of solid waste has caused discussions about the huge amount that is generated in Brazilian cities, in particular the waste from construction and demolition (CDW), called spoil. In many cases these wastes are disposed of improperly and even criminally in urban areas, causing serious economic, social and environmental problems. Due to the lack of public policies and appropriate management of such waste came up with the CONAMA, in its resolution nº 307 of 2002, the obligation of municipalities in deploy the integrated management of construction and demolition wastes for the resolution of problems caused by inadequate management and disposal of such waste. By following a methodology suggested by Pinto & González (2005), with adaptations of other authors, it is proposed in this work the lifting of a diagnosis of the CDW in the municipality of Guaratinguetá-SP, through theoretical analysis and field research, with purpose to guide the public servants in the elaboration and implementation of integrated management. The results must contain information necessary for that end, such as the knowledge of generators, agents, collectors and transporters, disposition areas and the disposal of waste

During the last centuries, the human being have been considered the center of the universe. The man believed that nature was at his disposal. Appropriated their processes, their cycles changed, redefined their spaces. Today, when faced with an environmental crisis which threatens the planet life, including the human life, the Science Education can contribute to a reconstruction of man-nature relationship in other terms. The transformation of teaching practices in the school environment, to be reflective, it is still a process that challenges the vast majority of teachers. As has been indicated by Guerra (2004), among others, the traditional teaching of content delivery is still very strong and certainly more deeply embedded in ideas and activities of the teachers who focus on environmental education. With it, a theory and pedagogical discourses in critical-reflexive actions is still a major obstacle. Therefore, new proposals for education and continuing education activities need to be formulated and presented based on the characteristics and needs breathing. Therefore propose changes in the way of teaching, where there is more room for a theory and praxis alone or with a only scientific truth. The scenery of society requires that knowledge is constructed to interconnect all disciplines, joining theory and practice so we can understand the whole and their relations in an integrated manner. It was proposed here a way to build a school and applying theoretical and practical activities involving experimental and seeking to meet the principles of Environmental Education for the training of citizens aware and critical. At the same time cares to use textbooks very rich in its pedagogical character that are present in schools and often are, forgotten and unused by teachers. From this way, I chose to Experimentoteca, ...(Complete abstract click electronic access below)

The use of polymeric materials has grown in recent years due to its high durability features, atoxicity, shaping versatility and environment resistance. However, while these features represent good advantages to several industry sectors, it results in one of the most serious environmental problems of contemporary society: the rising accumulation of these material, mainly due to the inadequate disposal of waste. Meanwhile, in order to minimize this problem, some mitigation techniques comes up (arises), among which the use of biodegradable polymers has been gaining attention. Because of their easily action of microorganisms, such material degrade more rapidly, becoming integrated to nature. Furthermore, due to the fact of biodegradation is a natural process, occurring through the action if micro-organisms in the environment itself, it is considered the “cleaner” alternative found so far to plastic components reincorporation in the nature. Among the micro-organisms capable of biodegradation process are the filamentous fungi. These micro-organisms have many advantages over the others, the major one being the capacity to produce a range of enzymes capable of degrading different materials. In this context, the present review made it possible to see the importance of this process as an agent of environmental preservation, suggest the use of blends to minimize the problems of cost and flexibility of biodegradable polymeric materials, as well as noting the lack of studies related to this subject nowadays

Taking as starting the environmental, social and economic impact of construction and demolition waste in Brazilian cities were created legal mechanisms for management and administration, seeking to minimize the impacts to the maximum, since the irregular deposition can be characterized as environmental crime. CONAMA Resolution No. 307 of 2002 establishing the mandatory implementation of an Integrated Management System Construction Waste and Demolition, guiding the classification and designation of the waste generating agents, collection agents and transporters, and the areas of culling and disposal of waste. The technical partnership between the Ministry of Cities, the Environment Ministry and the Caixa Econômica Federal, coordinated by Pinto & Gonzales (2005) Management in the work and management of construction waste, proposed a guidance manual to guide the implementation of a System Integrated Management of Construction Waste in Municipalities. The municipality of Guanambi in the state of Bahia, in full economic rise, lacks a waste management of construction and demolition, since there has areas for the disposal of waste being proposed in this paper the diagnosis of waste generation in the municipality as part of the methodology proposed by the work of Pinto & Gonzales (2005).

As new technologies improve, people’s lives gain in comfort and accessibility. However, along with these technologies comes a growth in “soon to fall into disuse” product consume, either because they have reached the end of their life cycle, or because they were substituted by newer and more advanced models. These electronic wastes are still with no certain destination, and could be donated to welfare companies, but the majority is thrown in wide open dumping grounds or landfills, where they can contaminate water and soil with their toxic components. This work seeks to evaluate the e-waste concept, their impacts in the environment and human life, as well as the current national and international e-waste management and destination, finally reflecting on international decisions that would be appropriate for the Brazilian system.

The inadequate disposal of municipal waste is one of the biggest environmental problems. The lack of long public politics makes this problem a challenge to their administrators. Finding a place for the disposal of waste is an easy task and the present work looks forward to a better understanding about the concepts involved in order to choose favorable areas for the development of sanitary landfills, minimizing environmental impacts. In this line of thought several areas in Rio Claro`s region were evaluated according to the environmental terms. The areas which were classified as good or almost good will have a more elaborated study such as field works, evaluation and understanding of the concepts analyzed so that there aren’t any waste of money, work, social and environmental waste in the area. These areas were analyzed according to secondary data such as geological and pedological formation and primary studies such as the assumption of the reality as showed in the map will be made in order to acquire better results.

Deconstructions, although hardly covered in Civil Engineering courses, are a very important field of study. Due to numerous factors, such as obsolescence, buildings life cycle comes to an end leading to their deactivations. Decommissioning is a process that intends to plan the hole deactivation by providing the cleaning of contaminated areas, avoiding risks to public health, as well as promoting a screening of generated waste, whether dangerous or not, offering their correct disposal or even reuse when possible. Decommissioning must be developed by a plan that covers from the recognition of the area until its releases to other uses. When this procedure is appropriate, attention must be paid to the cost effective of its implementation and to the cleaning standard that the plan intends to reach. The execution of the service allows to reuse the area, becoming productive again

CONAMA Resolution 307 / 02, in Article 4, states that the primary goal of those involved in the reuse process of construction and demolition waste is not the generation of such wastes, secondarily is the reduce, reuse, recycling and proper disposal of such material. The disposal problem of large volumes of waste generated coupled with the scarcity of natural resources and environmental degradation involved in the extraction process of such materials resulted in several studies, that after many analyzes proposed various forms of reuse and recycling . The NBR 15.116/04 provides requirements for the use of recycled aggregates in paving and concrete without structural function. This work aims to show the usage potential of recycled aggregates from waste generated in construction and demolition sampled Group AB Areias, Pindamonhangaba (SP) in order to meet the standards in Brazil, as well as the environmental contribution by reducing the use of raw materials extracted from nature. After stabilization and particle size analysis of the California Bearing Ratio and Proctor, obtained mixtures of recycled aggregates showed higher values submitted by the minimum standards related, with excellent potential for use in paving

The practice of regular physical activity has been considered a protective factor against the degenerative processes of the body, acting as a promoter of health, especially for risk groups such as obese and resistant groups exercise adherence as among the intellectually disabled (ID) . This study involved the administration of a training protocol and the physical parameters of longitudinal health in a subject about 43 years, intellectually deficient, hypertensive, obese and with a strong predisposition to develop diabetes and heart disease. The main objective of long-term program was to reduce body weight and normalize blood pressure (BP) after the student's physical activity and preferentially interfere with BP values at rest (ie before the daily schedule). The other objective was to improve general physical fitness. The protocol involved four meetings per week lasting one hour, in addition to participation in the program PROEFA (twice a week with sessions of one hour each), totaling 57 sessions spread over five months. The evaluation protocol included in each session the following tests: blood pressure measurements and heart rate, and amount of physical activity recorded via pedometer. Tests applied before and after the training included: anthropometric assessment, agility test, flexibility test, test drive through vertical and horizontal jumps and endurance to the test bench. The mass (kg) and BMI corresponded to the initial values of 127.7 kg and 42.05 kg m-2, and 5 months after 113.2 kg and 37.48 kg m-2, respectively. The waist-hip ratio was close to 1 after the intervention and this value corresponded to 0.98. For the test of agility (shuttle run) was not found improvement in performance. To test the values of the horizontal jump in pre-test were 52 cm and 56 cm post-test, vertical jump has been improved and...(Complete abstract click electronic access below)

This work is proposed to evaluate the potential risk of an inert landfill in the city of Rio Claro (SP), and also suggest a source for the contamination. The study was proposed because it is known that there were legal technicalities greetings to guarantee the quality of groundwater. Given the requirements of the Environmental Company of São Paulo (CETESB) were installed monitoring wells in the area; sampled to groundwater and its contamination was found. In addition, we analyzed the main characteristics of the area, the arrangement and characteristics of the waste, the local geology and the hydrogeological system, so that I could find the source of contaminants, and predict the direction of dispersion even in groundwater. At the end of the work presents conclusions, recommendations and proposals for mitigating action

The Guaraní aquifer has relevant importance both as a source of water for several urban centres and the development of agriculture and livestock. In recharge areas the aquifer is free and, therefore, subject to contamination of effluents and tailings deposited on soils that cover it. Thus, it becomes crucial not only its protection at all levels, as the knowledge of its degree of natural vulnerability. The present work used geostatistics modeling techniques to study the natural vulnerability of the Guaraní aquifer in the city of Rio Bonito, State of São Paulo, southeastern Brazil, where the Guarani aquifer is exposed. These techniques, extensively used in evaluation studies of mineral deposits and oil tanks, can be adapted to produce a spatial classification or a regionalisation of probabilistic indices of vulnerability. By ordinary kriging method maps of vulnerability classification were obtained. To determine the vulnerability of the aquifer was employed the Aquifer Vulnerability Index (AVI), which requires knowledge of unsaturated zone thickness and permeability. The final product was a map with probabilistic index of vulnerability of the Guaraní aquifer, which presented values between 0 to 0.33 years, framing the area studied in AVI class extremely high vulnerability

Currently exists a growing concern for the preservation of the environment Around the world, the environmental awareness in Brazil has strengthened during the past two decades. This concern in Brazil arises from the creation of mechanisms of supervision and punishment on the part of the environmental agencies. In order to meet the pertinent legislation many public and private companies have performed dehydration of waste generated in the process of treatment of industrial effluents, waste water and water treatment in order to reduce transport and disposal costs. The use of geotextile tubes has proven technically and economically feasible to be applied in various situations from water treatment to mining tailings. This work presents the solution adopted for an environmental liability in water treatment plant through the use of geotextile tubes to reduce the water content of the disposal. We evaluated the size distribution curves, Atterberg limits, and chemical composition of the residue. Found high concentrations of aluminum in the waste which would characterize environmental pollution if disposed off directly in nature with no treatment
