A vila do Morro: fragmentos de uma jornada sustentável

The ecology and sustainability have never been in question as they are today, this is because the planet has reached a situation in which problems related to consumption and waste production can not be ignored. Cities have become unhealthy and quality of life of urban man is increasingly impaired. As a form of escapism from the major centers, a significant number of people are looking for isolated communities and ecological order that there, in those isolated places, they are able to rescue the idea of community. The journalistic product The Village of the Mountain shows the daily life in an ecovillage and describes the challenges and ideologies of these people trying to build a more suitable place to live

Simplificação de malhas visando representações em multirresolução

The representation of real objects in virtual environments has applications in many areas, such as cartography, mixed reality and reverse engineering. The generation of these objects can be performed through two ways: manually, with CAD (Computer Aided Design) tools, or automatically, by means of surface reconstruction techniques. The simpler the 3D model, the easier it is to process and store it. However, this methods can generate very detailed virtual elements, that can result in some problems when processing the resulting mesh, because it has a lot of edges and polygons that have to be checked at visualization. Considering this context, it can be applied simplification algorithms to eliminate polygons from resulting mesh, without change its topology, generating a lighter mesh with less irrelevant details. The project aimed the study, implementation and comparative tests of simplification algorithms applied to meshes generated through a reconstruction pipeline based on point clouds. This work proposes the realization of the simplification step, like a complement to the pipeline developed by (ONO et al., 2012), that developed reconstruction through cloud points obtained by Microsoft Kinect, and then using Poisson algorithm

Um estudo sobre a resolução de problemas e suas relações com a afetividade

This research aims at examining the relationship between the performance of elementary school students Cycle I in problem solving and attitudes toward mathematics. For this, a research was conducted at a state school in the city of Bauru which was selected for convenience. Participants were randomly selected consisting of 75 students, of whom 21 were third years and 57 were of three classes of fifth year. The instruments used for data collection were: a informative questionnaire to characterize the students in age, grade, favorite subjects and the least liked, among others, an attitude scale, Likert type, to examine the attitudes toward mathematics; a interviews with 11 selected students according to scores on the attitudes and mathematical problems to be solved through the method of thinking aloud. The results showed that the major difficulties encountered by students in solving problems were: to understand the problems, formalizing the reasoning, recognize in the problem the algorithms needed for its resolution, make calculations with decimal numbers, do combinatorics, using the sum of equal portions instead of multiplying, self-confidence and autonomy in what he was doing, and others; participants with positive attitudes towards mathematics showed greater confidence to solve problems as well as a greater understanding on what was required by them, but were not detected significant relation between the attitudes and performance, since it was unfavorable

Tratamento de efluentes provenientes de abatedouro de bovinos por meio de reator enzimático seguido de reator aeróbio operado em bateladas sequenciais

Brazil has one of the largest cattle herds in the world, so the cattle slaughter is one of the most important economic activities in the Brazilian market. But this activity requires a high demand of water, resulting in serious problems about the correct disposal of wastewater generated in the process. This effluent has a high pollution load, becoming its receiving bodies (streams and rivers) unfit for various activities such as public water supply, recreation, fisheries. To minimize the environmental impacts of its industrial wastewater and fallow the local environmental legislation, refrigerators must make the treatment of these effluents. This study aimed to verify the efficiency of a enzymatic reactor, when occur hydrolysis of lipids present in the effluent industrial of an cattle slaughter industry. The treatment system used was composed of two separate reactors: one being the anaerobic fluidized bed reactor (AFBR), inoculated with immobilized enzymes on the matrix support, and the other by sequential batch reactor (SBR) inoculated with activated sludge. Whereas, the reactors have been developed and installed at the Wastewater Treatment Laboratory, Faculdade de Ciências e Tecnologia, UNESP, campus Presidente Prudente. The procedure operating occurred differently for each reactor: preparation and inoculation of enzyme granules, filling the reactor, hydrolysis, and AFBR emptying, filling, aerobic reaction, sedimentation, and emptying the SBR. We performed three experimental stages, with the first and second stage of the work were done reactor analyzes separately, and the third step of the analysis were made with the interconnected reactors...

Tratamento de recessões gengivais múltiplas: uma abordagem mais conservadora

Periodontal therapy has undergone significant changes in recent decades. While in the past the only goal was to restore gingival health, with no concern about the possible consequences of the disease treatment, currently the procedures are performed in a less invasive manner, to maintain aesthetic periodontal results or even recover them. Gingival recession is an alteration frequently found in patients and may be a complaint for causing various complications. For their treatment, several surgical techniques are reported in the literature. The techniques that are more predictable are those that associate a subepithelial connective tissue graft and a coronally repositioned flap. The original technique consists in performing two vertical incisions for an extensive release of the flap and its stabilization in a coronal position. Although this procedure is extremely widespread in the literature, the search for less invasive surgeries without the use of vertical incisions are the current aim of periodontal plastic surgeries, since they present several advantages. The aim of this paper is to demonstrate a case where adjacent, deep and multiple recessions were present resulting in aesthetic problems, which was resolved by a less invasive approach using a surgical technique in envelope and a subepithelial connective tissue graft.

Energetic exploitation from a hybrid PV-wind power micro-generation rural electrification

Hybrid system micro-generation integration of PV-wind power is presented by a form of energy in which problems resulting from variability in the intensity of wind and solar intensity are possible mitigation either by complementation between one source to another or the largest stability configured by the generate the system. Based on this context, this work aims to assessing the performance of a hybrid system PV-wind power energy small of a rural property for their electrification. The study has been developed at the Rural Laboratory Powering from Engineering Department of UNESP. In order to present this research, a hybrid system has been installed PV-wind power, composed of one 400Wp windmill and a 300 Wp PV-system. The results obtained allowed us to evaluate the solar and wind energy supplied ranked among 285 and 360 kWh electric power generated by the PV-wind power hybrid system stood between 25,5 and 31 kWh. At is to say achieving yield of approximately than 10% during one year observation period, i.e., it was concluded that the performance of the hybrid system depended essentially the energy received and generated by the PV-system and that there was complementation between generating wind power and PV-systems with regard to time of day and the annual seasons by confirming the technical feasibility of this kind system of micro-generation in small rural properties.

Multidisciplinary treatment ofadult patients with Class III malocclusion

This article describes the multidisciplinary treatment of an adult patient presenting with Angle Class III malocclusion, alteration of the mandibular position, vertical alveolar bone loss and absence of teeth in the lower posterior region. With advancing age the existence of occlusal interference due to loss of teeth or tooth structure is very common, resulting in periodontal problems due to occlusal trauma. The options for treatment of Class III malocclusion in adolescent and adult patients include compensatory orthodontic treatment in mild to moderate cases and orthognathic surgery for moderate to severe cases. The combination of various dental specialties enabled improvement in the social circumstances of the patient. This can be observed objectively by the final dental relationship and by the skeletal and tegumentary cephalometric comparison between the situation at the beginning and at the end of the treatment. The compensatory treatment performed permitted the successful correction of a Class III malocclusion in the clinical case presented.

Responsabilidad profesional del cirujano odontólogo: ¿qué piensan los abogados?

The number of lawsuits against dental surgeons has increased considerably in the recent years. Probably this is due to a change in the behavior of the patients, from a passive role in the past to a more demanding stance now. A transversal study was carried out to evaluate the point of view of lawyers in Araçatuba, SP, Brazil, about the professional liability of dentist, the major reasons for treatment failure, the dental specialties more involved in legal actions, their attitudes if they were submitted to an unsuccessful dental treatment, their opinion on what the dentist should do when a patient does not accept the treatment provided, and, finally, what a dentist should do when facing a civil liability action. A questionnaire was sent to 318 lawyers, and 151 of them answered it. The results show that for most lawyers an occasional failure in the treatment occurs due to professional incompetence and, in their opinion, the specialty more involved in legal problems is orthodontics (64.7%). Of the lawyers interviewed, 27.0% affirmed they would seek another dentist and also a lawyer, if they were subjected to an unsuccessful dental treatment. For 36.5% of them, the dentist should give further information and explain the reasons why the treatment did not meet the patient's expectations. According to 36.1% of the interviewees the best policy to be adopted by the dentist in case of a civil liability action would be an extra judicial settlement.
