O Programa de Desenvolvimento Sustentável da Produção Familiar Rural na Amazônia PROAMBIENTE, traz em sua proposta alternativas de uso dos solos e das florestas para a produção familiar. A comunidade de Monte Sião situada no município de São Domingos do Capim e participante do PROAMBIENTE foi a área escolhida para este estudo que trata das práticas sócio-culturais associadas as técnicas de produção de sistemas agroextrativistas de dez famílias que apresentam um histórico de utilização dos recursos biofísicos, tais como a extração do látex de seringais nativos, exploração madeireira lenhosas e sistemas intensivos de produção agrícola que a partir dos anos de 1990 adotaram os Produtos Florestais Não Madeiros PFNM como um elemento diferencial para a reprodução da agricultura familiar enquanto unidade de produção e consumo.

Apresenta uma investigação realizada junto aos habitantes de dois assentamentos produzidos informalmente em áreas pertencentes ao poder público municipal e ao governo federal em Belém, denominados Riacho Doce e Pantanal, a respeito do impacto na área resultante da implantação de um projeto de melhoria física e de desenvolvimento social, denominado Plano de desenvolvimento local, financiado pelo programa Habitar Brasil BID. A pesquisa identificou cinco grupos de moradores (não remanejados, em remanejamento, remanejados, indenizados, moradores de um assentamento em formação) definidos a partir do perfil sócio-econômico intra-domiciliar, e de sua localização relativa no assentamento. Os impactos do plano foram bastante diversos, os moradores com maior experiência acumulada nesse tipo de processo, e aqueles que não foram remanejados foram os mais beneficiados. Dentre remanejados destaca-se a satisfação com a melhoria física, e através do grupo em remanejamento e dos novos assentados observamos as limitações do processo, decorrentes de mudanças na gestão municipal, e da desarticulação do PDL com políticas setoriais aplicáveis ao tema.

O objetivo desta dissertação é analisar a implementação da política pública de ecoturismo para a região amazônica, com recorte no Programa de Desenvolvimento do Ecoturismo na Amazônia Legal (PROECOTUR), no pólo Belém/Costa Atlântica. Objetiva-se, ainda, analisar a participação dos atores sociais neste processo bem como a contribuição do Programa para o desenvolvimento sustentável na área em questão. Este estudo tem por base levantamentos bibliográficos, documentais incluindo fotografias e mapas e pesquisa de campo para a coleta de dados. Com base nestes procedimentos, descreve-se o processo de implementação deste Programa e os fatores que contribuíram para sua descontinuidade. A análise de políticas públicas de turismo, notadamente de ecoturismo, revela que estes são realidades raramente analisadas. Procura-se, então, contribuir para a ampliação dos conhecimentos sobre as mesmas. E, também, colaborar para que os atores sociais envolvidos compreendam a importância de sua participação no processo de implementação destas políticas, de tal sorte que se possa promover o desenvolvimento sustentável tão almejado.

O conceito de desenvolvimento sustentável e sua operacionalização emergem como uma necessidade de pensar em novas formas de mensurar o crescimento, daí o surgimento dos “Indicadores de Sustentabilidade”, criados para medir a sustentabilidade de um sistema, baseado em índices de diversas variáveis que apontam para a sustentabilidade ou não de uma região. Na Amazônia e no Estado do Pará, pouco se tem aplicado ferramentas de análise de sustentabilidade em suas mais diversas dimensões. Recentemente nesta região, foram criados os “Pólos de Produção do Biodiesel” através da Política Nacional de Produção do Biodiesel – PNPB e neste sentido, destaca-se o Município de Moju, no Pará, como um dos maiores produtores de dendê. Apesar da enorme expansão de cultivo de dendezeiro neste município, há dúvidas sobre a capacidade de Moju de receber uma política pública como essa, que se configura em novas territorialidades e novas dinâmicas sociais, econômicas e ambientais e trazem imensos desafios, que requerem uma capacidade de gestão ambiental forte. Dessa forma, o estudo dedica-se a analisar o nível de sustentabilidade do município de Moju e a capacidade de gestão ambiental deste município. Foram realizadas entrevistas e busca de dados secundários e para a análise de sustentabilidade usou-se como ferramenta de avaliação o Barômetro da Sustentabilidade. Observou-se que este município tende a baixa sustentabilidade com poucos avanços socioeconômicos e ambientais, o que denota a fragilidade do município nas questões socioambientais. Em geral, o município possui habilitação para exercer a gestão ambiental plena, ou seja, apresenta uma estrutura administrativa considerada desejável, porém sua estrutura operacional ainda é deficitária ou ineficaz, o que trará certamente problemas para a condução do PNPB.

In this work was developed a program capable of performing automatic counting of vehicles on roads. The problem of counting vehicles is using expensive techniques for its realization, techniques which often involve manual counting or degradation of the pavement. The main motivation for this work was the importance that the vehicle counting represents to the Traffic Engineer, being essential to analyze the performance of the roads, allowing to measure the need for installation of traffic lights, roundabouts, access ways, among other means capable of ensuring a continuous flow and safe for vehicles. The main objective of this work was to apply a statistical segmentation technique recently developed, based on a nonparametric linear regression model, to solve the segmentation problem of the program counter. The development program was based on the creation of three major modules, one for the segmentation, another for the tracking and another for the recognition. For the development of the segmentation module, it was applied a statistical technique combined with the segmentation by background difference, in order to optimize the process. The tracking module was developed based on the use of Kalman filters and application of simple concepts of analytical geometry. To develop the recognition module, it was used Fourier descriptors and a neural network multilayer perceptron, trained by backpropagation. Besides the development of the modules, it was also developed a control logic capable of performing the interconnection among the modules, mainly based on a data structure called state. The analysis of the results was applied to the program counter and its component modules, and the individual analysis served as a means to establish the par ameter values of techniques used. The find result was positive, since the statistical segmentation technique proved to be very useful and the developed program was able to count the vehicles belonging to the three goal..

In this paper we investigate the quantum phase transition from magnetic Bose Glass to magnetic Bose-Einstein condensation induced by amagnetic field in NiCl2 center dot 4SC(NH2)(2) (dichloro-tetrakis-thiourea-nickel, or DTN), doped with Br (Br-DTN) or site diluted. Quantum Monte Carlo simulations for the quantum phase transition of the model Hamiltonian for Br-DTN, as well as for site-diluted DTN, are consistent with conventional scaling at the quantum critical point and with a critical exponent z verifying the prediction z = d; moreover the correlation length exponent is found to be nu = 0.75(10), and the order parameter exponent to be beta = 0.95(10). We investigate the low-temperature thermodynamics at the quantum critical field of Br-DTN both numerically and experimentally, and extract the power-law behavior of the magnetization and of the specific heat. Our results for the exponents of the power laws, as well as previous results for the scaling of the critical temperature to magnetic ordering with the applied field, are incompatible with the conventional crossover-scaling Ansatz proposed by Fisher et al. [Phys. Rev. B 40, 546 (1989)]. However they can all be reconciled within a phenomenological Ansatz in the presence of a dangerously irrelevant operator.

The current study is a piece from the original project entitled "Diagnosis of the Artistic Gymnastics Development Program in Brazil". Among others issues, the coaching philosophy of coaches who are developing gymnasts that may be representative of the national team was a matter of analysis. We interviewed 46 coaches from 29 sports institutions in Brazil. As data collection we used a semi-structured interview and for data treatment we adopted the content analysis method of Bardin (2010). We have found out that there is an inconsistent philosophical basis, and in many institutions this has been mixed up with the objectives of the training program or just doesn't exist. This fact needs consideration and criticism, but we know that the coaching philosophy is not developed during the coaching education courses.

Abstract Background Vampire bat related rabies harms both livestock industry and public health sector in central Brazil. The geographical distributions of vampire bat-transmitted rabies virus variants are delimited by mountain chains. These findings were elucidated by analyzing a high conserved nucleoprotein gene. This study aims to elucidate the detailed epidemiological characters of vampire bat-transmitted rabies virus by phylogenetic methods based on 619-nt sequence including unconserved G-L intergenic region. Findings The vampire bat-transmitted rabies virus isolates divided into 8 phylogenetic lineages in the previous nucleoprotein gene analysis were divided into 10 phylogenetic lineages with significant bootstrap values. The distributions of most variants were reconfirmed to be delimited by mountain chains. Furthermore, variants in undulating areas have narrow distributions and are apparently separated by mountain ridges. Conclusions This study demonstrates that the 619-nt sequence including G-L intergenic region is more useful for a state-level phylogenetic analysis of rabies virus than the partial nucleoprotein gene, and simultaneously that the distribution of vampire bat-transmitted RABV variants tends to be separated not only by mountain chains but also by mountain ridges, thus suggesting that the diversity of vampire bat-transmitted RABV variants was delimited by geographical undulations.

Em sua dimensão político-societal, competência começa a fazer parte da agenda dos modelos de desenvolvimento de pessoas nas organizações, sobretudo, sob o mote da sustentabilidade. Partindo dessa premissa, este artigo investiga se há conteúdo relevante por trás dessas propostas educativas ou se elas, simplesmente, tornam os pressupostos da sustentabilidade funcionais ao sistema corporativo sem que alguma mudança substancial esteja de fato em curso. Mais especificamente, este estudo se apoia em dois eixos: primeiro, procura discutir o conceito de competência societal; segundo, busca analisar uma experiência de educação executiva de desenvolvimento de gestores em questões relacionadas à sustentabilidade, o Programa de Desenvolvimento de Líderes para Sustentabilidade (PDLS). O estudo, de natureza qualitativa, foi conduzido em uma instituição financeira que se tornou destaque na mídia e passou a ser reconhecida como ator social destacado, por levar à frente a ideia de inserir a sustentabilidade na prática dos negócios. Os resultados revelam um programa impactante que se, por um lado, permitiu que o discurso dos gestores se tornasse competente, por outro, nem sempre correspondeu a uma ação que atingisse o mesmo patamar de excelência. Os gestores participantes adquiriram conhecimento e visão crítica, mas, ainda, enfrentam dificuldades para harmonizar os objetivos do negócio com princípios de sustentabilidade. Mesmo com formação avançada sobre o tema, os paradoxos da ação permanecem presentes quando se trata de dar vida a esta ideia força chamada sustentabilidade.

The prevalence of Ventilated Improved Pit (VIP) latrines in Ghana suggests that the design must have a high user acceptance. The two key factors attributed to user acceptance of a VIP latrine over an alternative latrine design, such as the basic pit latrine, are its ability to remove foul odors and maintain low fly populations; both of which are a direct result of an adequate ventilation flow rate. Adequate ventilation for odorless conditions in a VIP latrine has been defined by the United Nations Development Program (UNDP) and the World Bank, as an air flow rate equivalent to 6 air changes per hour (6 ACH) of the superstructure’s air volume. Additionally, the UNDP determined that the three primary factors that affect ventilation are: 1) wind passing over the mouth of the vent pipe, 2) wind passing into the superstructure, and 3) solar radiation on to the vent pipe. Previous studies also indicate that vent pipes with larger diameters increase flow rates, and the application of carbonaceous materials to the pit sludge reduces odor and insect prevalence. Furthermore, proper design and construction is critical for the correct functioning of VIP latrines. Under-designing could cause problems with odor and insect control; over-designing would increase costs unnecessarily, thereby making it potentially unaffordable for benefactors to independently construct, repair or replace a VIP latrine. The present study evaluated the design of VIP latrines used by rural communities in the Upper West Region of Ghana with the focus of assessing adequate ventilation for odor removal and insect control. Thirty VIP latrines from six communities in the Upper West Region of Ghana were sampled. Each VIP latrine’s ventilation flow rate and micro-environment was measured using a hot-wire anemometer probe and portable weather station for a minimum of four hours. To capture any temporal or seasonal variations in ventilation, ten of the latrines were sampled monthly over the course of three months for a minimum of 12 hours. A latrine usage survey and a cost analysis were also conducted to further assess the VIP latrine as an appropriated technology for sustainable development in the Upper West Region. It was found that the average air flow rate over the entire sample set was 11.3 m3/hr. The minimum and maximum air flow rates were 0.0 m3/hr and 48.0 m3/hr respectively. Only 1 of the 30 VIP latrines (3%) was found to have an air flow rate greater than the UNDP-defined odorless condition of 6 ACH. Furthermore, 19 VIP latrines (63%) were found to have an average air flow rate of less than half the flow rate required to achieve 6 ACH. The dominant factors affecting ventilation flow rate were wind passing over the mouth of the vent pipe and air buoyancy forces, which were the effect of differences in temperature between the substructure and the ambient environment. Of 76 usable VIP latrines found in one community, 68.4% were in actual use. The cost of a VIP latrine was found to be equivalent to approximately 12% of the mean annual household income for Upper West Region inhabitants.

Methods of heat detection were compared in the Mid- Crest Area Cattle Evaluation Program (MACEP) heifer development program in the 1998-breeding season. A total of 189 heifers from thirteen consignors entered the program on November 10, 1997. These heifers were condition scored, hip height measured, weighed, disposition scored, booster vaccinated, and treated for parasites at the time of arrival. Determination of the heifer’s mature weight was made and a target of 65% of their mature weight at breeding was established. The ration was designed to meet this goal. The heifers were kept in a dry lot until all heifers were AI bred once. The heifers were periodically weighed and condition scored to monitor their gains and the ration was adjusted as needed. The estrus synchronization program consisted of an oral progesterone analog for 14 days; 17 days after completion of the progesterone analog treatment a single injection of prostaglandin was given and the heifers were then estrus detected. Two concurrent methods of estrus detection were utilized: 1) Ovatec â electronic breeding probe (probe), 2) HeatWatchâ estrus detection system (HW), and 3) a combination of probe and HW. Probe readings were obtained each 12 hours and the heifers were continuously monitored for estrus activity using the HW system. The probe was used as the primary estrus detection method and the HW system was used as a back-up system. Those heifers that did not demonstrate any estrus signs prior to 96 hours post prostaglandin treatment were mass inseminated at 96 hours. Post AI breeding, 151 of the heifers were placed on pasture and ran with clean-up bulls for 60 days. The remaining heifers left the program after the AI breeding was completed. Pregnancy to the AI breeding was determined by ultrasound on June 29, 1998. Results from using both probe and HW were 60% pregnant by AI, probe alone was 32% pregnant by AI, and HW alone was 27% pregnant by AI. The result of mass insemination was 20% pregnant by AI.
