Cardoso Island, settled in the south of paulista region, is characterized by its ecological importance due to the great biodiversity of Mata Atlântica and for accommodating several kinds of ecosystems as mangroves, which were considered by UNESCO as human natural ownership. The mangroves are among the most important marine ecosystems, known as warranty of biological productivity and diversity and supply of food and economical resources to the local population. Although the island has been transformed in a state park for preservation, it hasn’t become free from environmental impacts made by antropical activities. This way it was proposed a rebuilt of an evolutionary process in the region, having as an objective to subsidize programs of environmental conservation and planning , aiming to a sustainable development. For this it was used a isobasis methodological analyses where by the drainage channels and its confluences makes relative maps to the different base levels represented by the isobasis, characterizing itself by an attempt to rebuilt the preterit local landscape. There were elaborated eight maps referring to four orders of confluences met in the region of Cardoso Island and round it where you can conclude it is about an appropriate methodology to rebuilt preterits environments that specially aim to actions of environmental planning and conservation.

This academic work has as its objective to demonstrate the fundamental role of communication as a tool towards implantating an environmental management project in organizations, aswell as familiarizing with the complex relashionship be-tween green businesses and its publics. The concern involving environmental prob-lems are increasing and it directly affects the consumer’s choice and their requests on organizations’ behavior. The integration with all sectors of economy is necessary as a part of a developing process that has as its main objective the environmental conservation and therefore the quality of human life on planet. There is also the question of how in the process of communication there is not an only way of interven-tion, but a continuous reciprocal action. The work is accomplished with an analyses of the green management communication of the business Grupo Abril

The porcine activity is characterized by its great pollution capacity, generally produce loads of waste that usually are released in superficial water or soil without concern for the consequences to the environment. With this in mind, this study aimed to adjust the porcine production to the protection of water resources, in particular, Ribeirão dos Pinheirinhos in the town of Torrinha (SP), through inventory and diagnosis of the environmental impacts already present and environmental hazards linked to the activity in question. To achieve the proposed objectives, the productions of porcine on the studied area were raised and georeferenced, viewed and analyzed according to the technical and scientific literature. The production visited showed to be at odds with the protection of water resources due to lack of technical criteria in the development of treatment systems and waste handling, indiscriminate use of effluent and waste in the fertilization of crops and the lack of knowledge of producers on the influence of porcine waste into the environment. Based on these results, were set guidelines for action in the environmental awareness of farmers, to stimulate voluntary and conscious initiatives of environmental conservation in the direction of settlement of the activity.

One of the ways to minimize the effects of unproductive time caused by tool wear can be achieved by introducing an efficient system of lubrication and cooling in the process. However, in the last decade the research had the goal to restrict the maximum use of refrigerants and / or lubricants in metal-mechanical production. The important factors that justify this procedure include the operational costs of production, ecological issues, and the legal requirements of environmental conservation and preservation of human health. The purpose of the proposed work is the study of machining by turning with the focus on the influence caused by the application of cutting fluid in several ways of application (abundant and MQF) and also by comparing the results obtained by machining without the presence of fluid . For this purpose, the turning tests are conducted using an aluminum alloy (AA 7075). The response variables to be analyzed were obtained from the roughness (Ra and Ry), the stresses presented (VB) and their progression in relation to the cutting length achieved, the type of chip formed, in addition to changes in the degree of finish (roughness) presented by the turned parts. The results of this study should provide more detailed information about the actual influence of cutting fluids in turning this alloy, which are characterized by high rates of deformation when the formation of damaging your chip machining and also the quality of surface generated. Therefore, it is expected to provide subsidies to promote the optimization of machining this alloy making the most of the role of cutting fluid

The present work aims to conduct a study of the economic feasibility of the implementation of variable frequency inverters in pump systems with variable flow rates. The concern with the reduction of energy expenditure in industries raised in 2001 due to the energy crisis that hit Brazil at that time, forcing industries to reduce their electric costs under penalty of fines if this were not done (MOREIRA, 2008). Frequency inverter is an electronic device that allow greater control in the operation of pumping systems and also a reduction in electrical consumption, being a viable solution to achieve a reduction in energy consumption. For the development of this work, approaching important topics in pumping systems was necessary in order to make a correct choice of hydraulic pumping and also other components responsible for the operation of the system , such as electric motors and frequency inverters. In the case study, a theoretical analysis of the behavior of electrical consumption in systems with variable flow rates was performed, comparing when the system is operated via frequency inverters and when the system is operated without such a device. As expected, the result of the implantation of the device was quite satisfactory, and the primary goal of reducing energy expenditure was achieved. Also important to highlight the environmental issue of this work, as all forms of energy production affects nature in some way, achieving a reduction in consumption also contributes indirectly in environmental conservation

We assessed the efficacy of three different forest intervention techniques, in terms of phytosociological and edaphic responses, that were implemented in 2007. In a farm where trees are planted and managed for cellulose production as well as set aside for environmental conservation, four stands were analysed: three of them were considered degraded and were managed using different intervention techniques (transposition, perch, and abandonment), and a fourth stand comprising pristine vegetation was considered a control (reference). Floristic and phytosociology data were collected in three 10 × 10 m plots established in each stand. Also, a total of 48 soil samples were collected to analyse physical and chemical attributes of the topsoil for the different stands. In terms of biodiversity, all the treatments showed significantly lower values when compared to the reference area. However, the soils in all the treatment and reference stands are similar in terms of physical and chemical attributes. Taking into account the specificities of each restoration technique, we verified that the integrated use of a set of management practices, constituted by the (1) abandonment of the area and (2) following a selective killing of the eucalyptus, is the most suitable and promising model to provide fast and effective restoration in terms of environmental indicators.

The permanent preservation areas (PPA) established by Brazilian law are there to protect the natural environment. With the expansion of space occupied by man and development of economic activities in these areas were engaged in conflicts characterized PPA, where the use is other than the natural vegetation. According to these paradigms work aims to raise these conflict areas in the River Basin Capivara, Botucatu (SP) with the help of GIS Ilwis 3.4, topographic maps of IBGE and satellite images CBERS 2B. The map was generated from PPA in the GIS by distance calculation in relation to drainage, springs and break line on Cuesta de Botucatu. The classes of land use and natural vegetation were determined by interpretation of satellite images and field visits to check their veracity. With the cutting of the map of land use and natural vegetation in relation to PPA unit it was determined that the total 44,63% PPA is in conflict occupied by pasture, forest plantation, orange, annual crops, farms and irrigated rice project in lowland. This diagnostic characterizes the degradation of the environment and highlights the need to harmonize the economic and urban development with the preservation of the environment to ensure sustainability of the region.

The aim of the study is to demonstrate the occurrence and usage of the Tucumã (Astrocaryum vulgare Mart.) in rural areas of the Municipality of Irituia, in the State of Pará (Brazil), since the use of the palm part of the traditional culture of communities of farmers, riparian and quilombola, used in curing diseases in human and domestic animals, building shelters, obtaining fibers, production of tools and crafts, hunting and fishing. In addition to the uses reported by the population, tucumã has potential for the production of oil and biodiesel. In this sense, the Federal University of Pará – UFPA, in a partnership with the Irituia’s Municipal Government, is studying the implementation of an oleaginous processing plant in the municipality, among them, and includes the Tucumã as a potential source. Such proposal stipulates the production in the agroforestry system, as an alternative to the slash and burn agriculture in the region, reconciling environmental conservation with territorial rural development. Considering the results obtained in the field, it has been found an average of 9.4 stumps per hectare, each stump having 7.7 stipes and 4.7 racemes with up to 146 fruits. If all the Tucumã’s stumps were kept until they reached their average productivity capacity, it is estimated that the fruit production in the rural area of the municipality would be around 132.060 tons, which could produce up to 12.665,4 tons/year of pulp oil and 4.768,4 tons/year of nut oil, confirming the supply of raw material to move this productive chain.

Attention was focused on the Monk Parakeet (Myiopsitta monachus) in New York State in 1971 when the first successful breeding record was documented for the state although Monk Parakeets had been noticed in New York and New Jersey since 1968 (Bull, 1971). Since 1971 awareness of the bird’s potential for becoming an established species in New York has spread through several segments of the state’s populace. This awareness has been created primarily through two articles in the magazine published by the New York State Department of Environmental Conservation (DEC), The Conservationist (Trimm, 1972) (Trimm, 1973); several articles in popular magazines, Parade, Yankee, Sports Afield; journals, American Birds and Kingbird; county cooperative extension bulletins and newsletters; and in numerous newspapers throughout the Northeast. The Monk Parakeet is about 12 inches long (Mourning Dove size), weighs about 90 grams, and is native to Argentina and other temperate regions of South America. The bird is pale green with a soft gray forehead and breast, some blue on the flight feathers and a flesh-colored bill. They are gregarious throughout the year. The Monk Parakeet differs from other members of the parrot family in that it builds large communal nests of sticks. Each pair of parakeets has its own private compartment with a downward-pointing tunnel entrance from the inner unlined compartment. The nest is used as sleeping quarters year round and live twigs cut by the bird are continually added to the structure (Bump, 1971). A brief review of the bird’s history in New York shows that the bird remained a mere curiosity until 1972. At that time, because the population seemed to be increasing and because information gleaned from the literature and from those with first-hand experience with the bird in its native haunts of South America indicated that the bird posed a serious potential agricultural problem, several prominent individuals, birding and conservation societies, and state and federal agencies took the position that the bird should be retrieved or removed from the wild.
