The flow of Ricci is an analytical tool, and a similar equation for heat geometry, a diffusive process which acts on a variety of metrics Riemannian and thus can be used in mathematics to understand the topology of varieties and also in the study geometric theories. Thus, the Ricci curvature plays an important role in the General Theory of Relativity, characterized as a geometric theory, which is the dominant term in the Einstein field equations. The present work has as main objectives to develop and apply Ricci flow techniques to general relativity, in this case, a three-dimensional asymptotically flat Riemannian metric as a set of initial data for Einstein equations and establish relations and comparisons between them.

The use of mobile robots in the agriculture turns out to be interesting in tasks of cultivation and application of pesticides in minute quantities to reduce environmental pollution. In this paper we present the development of a system to control an autonomous mobile robot navigation through tracks in plantations. Track images are used to control robot direction by preprocessing them to extract image features, and then submitting such characteristic features to a support vector machine to find out the most appropriate route. As the overall goal of the project to which this work is connected is the robot control in real time, the system will be embedded onto a hardware platform. However, in this paper we report the software implementation of a support vector machine, which so far presented around 93% accuracy in predicting the appropriate route.

This paper aims to discuss and reflect the trajectory of inclusive education in Brazil, for such it is important to bring as she is becoming. The notion of inclusion is directly related to the right to equal that from the eighteenth century marks the social constructions and political ideas and social relations stuck on democracy and / or equality in the world, as well as in Brazil. But what is presented in the practice of social relations today is as an equal and non-homogeneity and recognition of identities, cultures and specific needs of each. Inclusion and integration are being discussed all over the country, but it's still a fact that deserves more involvement by all actors of society. She was raised primarily in the form of laws, decrees, documents, and now gaining ground in academic research showing the differences between the two terms, and finally is reaching the school, although it is still insufficient participation, with regard to transformation of the trader concerned with working in a school for all, along the lines of an egalitarian society with respect for diversity. To this end this paper argues the importance of continuing education in all areas of knowledge for the implementation of public policies actually everyone regardless of their differences.

This paper presents a case report with the use of short dental implants and immediate prosthesis placement. After 13 months of follow-up, peri-implant probing values are near 1.87 mm and ISQ values around 78.56.

The rehabilitation of edentulous areas with osseointegrated dental implants is a well-documented, predictable procedure in the literature, with high success rates. However, the lack of bone at the recipient bed or proximity to anatomic structures limits the rehabilitation procedure especially at the posterior mandible. Thus, short implants are an alternative treatment for such cases of severe bone resorption. The purpose of this study was to review the success rate of short implants, especially those based in the posterior mandible and to show a clinical case. A literature review was made on electronic databases PubMed and Bireme with articles published between the years 2005 to 2012, using the keywords "short dental implants". It was concluded that the success rates of short implants are similar to those presented by conventional implants but still related to their geometry and surface treatment. Also, short implants can be considered as a viable alternative for the rehabilitation of severely resorbed jaws. However, many authors consider that more research is necessary when a short implant is compared to a long dental implant.

Jaws atrophy represents a great challenge to Implantology regarding rehabilitation of edentulous areas. This paper reports an extreme mandibular atrophy with only 9mm of height between the mental foramina. In these situations, treatment options include bone augmentation techniques, transmandibular, or short dental implants. It is well accepted that bone grafts to improve height do not have good predictability. Besides, osteogenic distraction is associated with a great patient discomfort and transmandibular implants are related with high failure rates. Also, surgical-prosthetic rehabilitations with short dental implants had been associated to good success rates. The purpose of this clinical case is to report a severe mandibular atrophy, successfully treated with four short dental implants between mental foramina for implant-supported prosthesis.

The contemporary implant dentistry is in constant technological development, improving the oral rehabilitation process of partial or totally edentulous patients. On the other hand, anatomical limitations, such as the maxillary sinus and the mandibular canal in the posterior region of the jaws can limit the implant placement. Furthermore, due to the absence of dental elements, alveolar ridge atrophy is frequently observed. This aspect represents a loss either in quantity or quality of the bone tissue available for the dental implant rehabilitation. To make possible the dental implant rehabilitation even in adverse conditions, some solutions have been considered, such as the use of short implants (≤ 10 mm length) and/or small diameter implants (2,8; 3,3 and 3,5 mm width). The aim of this study is to present a literature review considering the use of short implants in oral rehabilitation, presenting the currently view of the matter. Based on the literature review, the use of short implants produced similar clinical success to conventional implants (greater than 10 mm in length). Therefore, its use can be considered a viable alternative, where anatomical limitations are present.

Abstract This paper discusses the quality of basic education legitimized by the external evaluation and publicized by the Basic Education Development Index (IDEB) - an index that combines the performance of students in the assessment and the school flow, culminating with the establishment of an objective parameter (grade) that aims to reflect the Brazilian educational quality. The arguments are based on the premise that these two elements are incipient to determine the quality of education in the country without taking into account other factors that affect quality, namely: socio-economic and cultural level of the students, teacher training, enhancement of teaching, tangible and intangible working conditions, school management, school infrastructure, supplies, etc. The reflection leading to the debate on the lack of evidence to establish the quality of education travels the ways of the external evaluation in Brazil, the technical rationality of the school management referenced primarily by the IDEB and its governance to achieve the goals determined by this index. The purpose of this essay is to contribute to the current debate on the IDEB as a proposer and mobilizer of policies for the Brazilian public schools.
