Automatic video surveillance system has been a frequent topic of research due to the large number of promising applications. In this research, we developed a tracking and counting people system, as well as suspicious activities detector. The model tracks individual objects as they pass through the field of vision of the camera using vision algorithms to classify the activities of each person, and according to this features, detect dangerous situations. This dissertation includes a review of several techniques trying to develop a robust and low computacional costs system to be used in glass door barrier turnstiles avoiding fraud

This study will focus on one part of Traditional Chinese Medicine (TCM), acupuncture - utilized as therapy method for pathologies treatment in humans and animals - , as well as its main techniques. Acupuncture is one branch of TCM, originated from theoretical and empirical knowledge accumulated by popular medicine. Currently, researches performed in humans and animals have shown the effectiveness of this method as an assistance or alternative in illnesses treatment. Besides that, professionals are not merely looking for orthodox medicine knowledge, but also specializations and improvement over the complementary therapies area. There are diverse studies and researches which were and are being done in veterinary, relating the effectiveness of acupuncture in small and large animals. In comparison, in the wild animals’ area the numbers of studies is smaller. However, it is expected that this number increases over the fact that some of these animals’ species are entering the pet market and also because of the possibility of using these methods for treatment and prevention of diseases on zoo animals or other animals kept in captivity

A formação de mosaicos de habitats em regiões de reflorestamento e outras atividades antrópicas acabam influenciando na comunidade de mamíferos silvestres, de diferentes formas. Os mamíferos de médio e grande porte têm importantes funções como dispersores de sementes, polinizadores e predadores. Concomitantemente, este grupo de animais vem se tornando cada vez mais ameaçado na Mata Atlântica, especialmente no estado de São Paulo. O presente estudo realizou a caracterização da comunidade de mamíferos silvestres de médio e grande porte, presente em dois ambientes: fragmentos de vegetação natural e talhões de eucalipto. Para tanto, foram utilizados métodos indiretos de registro: observação de pegadas em transectos lineares e em armadilhas de areia. De acordo com a curva acumulativa de espécies, o esforço amostral se mostrou suficiente para registrar as espécies que vivem no ambiente de mata e eucalipto. A riqueza de espécies na mata foi maior que a riqueza nos eucaliptos, sendo este último, um ambiente preferencialmente de passagem, enquanto a mata é um habitat natural para os mamíferos. Entretanto, o ambiente de eucalipto se mostra importante para diversas espécies de mamíferos, que utilizam este ambiente como abrigo e para busca de recursos

Estima-se que anualmente, em função do tráfico de animais silvestres, cerca de 12 milhões de espécimes sejam retirados de nossas florestas, sendo que apenas uma ínfima porcentagem de indivíduos é recuperada e destinada à soltura com o devido rigor técnico. O tráfico de animais silvestres constitui um dos fatores mais relevantes da destruição da fauna, acarretando em um desequilíbrio na estruturação e manutenção dos ecossistemas. Este comércio ilegal constituise o terceiro maior do mundo, perdendo apenas para o tráfico de narcóticos e armas. Assim, para otimizar o processo de soltura da fauna como estratégia para conservação de espécies torna-se necessário uma análise quantitativa e qualitativa da fauna atendida e dos procedimentos realizados nos Centros de Triagem de Animais Silvestres (CETAS). Nesse sentido, o presente trabalho teve como objetivo fazer uma caracterização da fauna recebida e uma avaliação dos procedimentos realizados em dois CETAS, além de discutir sobre a importância desse órgão na triagem, reabilitação e conservação de animais silvestres. O presente estudo é justificado pela escassez de informações sobre a fauna retirada da natureza. Estas são necessárias para servir de base científica para a adoção de políticas públicas para o combate ao tráfico de animais silvestres; elaborar um programa de fauna que contemple a triagem e destinação adequada e contribuir para o desenvolvimento de trabalhos educativos com o fim de esclarecimento da sociedade. Foram analisados o “Livro de Registro” do CETAS da Fundação Animália e o “Livro de Plantão” do CETAS DEPAVE – 3, bem como os “Relatórios CETAS” que esses dois Centros enviaram ao IBAMA. O período escolhido foi do ano de 2003 a 2008. Os dados foram compilados e organizados em planilhas do Microsoft Office Excel e foram elaborados tabelas e gráficos para análise dos resultados.

This work presents the development of a graphical interface to the Lock-in Amplifier, which is used in physiological studies on the motility of the gastrointestinal tract in rats and signal processing. With a simple and low cost instrumentation, the resources offered by the virtual interface of LabVIEW software allows the creation of commands similar to the actual instrument that, through communication via standard serial port, transmits data between a PC and peripheral device performing specific and particular needs in the amplifier. Created for the lock-in amplifier model SR830 Stanford Research Systems, the remote manipulation gives the user greater accessibility in the process of configuration and calibration. And, since the software is installed, there is the advantage of eliminating the need of purchase new devices to upgrade the system. The commands created were made to perform six basic modifications that are used in routine of the Biomagnetism Laboratory. The instrumentation developed has the following controls: Amplitude, Frequency, Time Constant, slope low pass filter, sensitivity and offset

Abstract : The objective of this study was to evaluate quantitatively and to describe qualitatively the process of bone repair in the interface of receptor bed and graft autogenous bone block with or without a e-PTFE membrane, in osteopenia induced rats. To this end, we used forty-eight Wistar rats weighing about 300g, in which, with the aid of 4.1 mm trephine a graft was removed from the parietal bone and fixed to the surface of the left mandibular ramus. The animals were randomly divided into four experimental groups: Group 1 (n=12): SHAM operated and autogenous bone graft only; Group 2 (n=12): SHAM and autogenous bone graft covered by e-PTFE membrane; Group 3 (n=12): ovariectomized rats (OVX) and autogenous bone graft only; Group 4 (n=12): OVX and autogenous bone graft covered by e-PTFE membrane. The animals in each group were sacrificed at three time periods: 21, 45 and 60 days, each time with 4 animals per group. The specimens were decalcified and included, the sections were stained with HE and subjected to histological and histomorphometric analysis in light microscopy. The results of the ANOVA showed that the variables on the condition (OVZ and SHAM), and the time (21, 45 and 60 days) were statistically significant, and can be established with the Tukey test (5%) that the period 21-day differs significantly from the periods of 45 and 60 days, which did not differ among themselves. The descriptive histological analysis showed integration of the graft in all animals. It was concluded that the initial integration of the graft bed was negatively affected in the presence of induced osteopenia, and that the use or not of a e-PTFE membrane did not interfere in the process of integration

The aim of this study was to evaluate the clinical, tomographic, and histological similarity within the use of HA+β-TCP (Boneceramic) alone or associated with enamel matrix derived (EMD) proteins in sinus lifting procedures with subsequent dental implant placement. We selected two patients with residual bony ridges between 3 mm and 5 mm in height in need of bone grafts. Six months later, eight implants were installed (two implants at each site). Biopsies were made, and the tissue was processed and stained with HE solution. Tomographic evaluation showed bone height gain up to 10.0 mm on average. Histology showed new bone formation for both groups, with similar bone density and trabecular interconnectivity. It can be concluded that the HA+β-TCP graft isolated or associated to EMD provided bone height gain in sinus lifting procedures, with similar clinical, tomographic and histological characteristics.
