A demanda por recursos naturais de parte da sociedade, juntamente com a necessidade de conservação ambiental para as gerações futuras, representa um conflito cada vez mais presente nas relações do homem com a natureza. A avaliação de possíveis impactos e sua mitigação, assim como o estabelecimento de mecanismos de compensação ambiental, se fazem por meio de processos de licenciamento mediados pelo poder público, os quais devem ser embasados em estudos com o maior detalhamento possível. Nesse sentido, este livro busca apresentar informações relevantes para dar subsídio ao processo de licenciamento de mineração de areia no Lago Guaíba, localizado no Rio Grande do Sul.
The ‘Aquatic Habitat Conservation in South America’ Symposium occurred during the XXI Brazilian Society of Ichthyology Meeting. The proceedings were published as a special issue in the Journal of Fish Biology (vol. 89, Number 1, June 2016). In this special issue, authors provided an analytical overview of problems faced by the conservation of fishes and aquatic habitats of South America. Habitat loss emerged as the greatest concern for all South American aquatic ecosystems, with a long list of causes related to unsustainable development models. Based on this finding, we would like to extend this topic to other continents, different climates, fauna and flora around the world. Our goal is to provide a comprehensive and multidisciplinary overview of variables that influence flora and fauna distributions and shape their ecological interactions within aquatic ecosystems
Este livro apresenta, de forma acessível, os temas abordados na disciplina Tópicos Especiais (DERAD 25), oferecida no Curso de Graduação Tecnológica Planejamento e Gestão para o Desenvolvimento Rural (PLAGEDER) da UFRGS, na modalidade a distância. Dividida em quatro partes, esta obra apresenta as bases do conhecimento sobre impacto ambiental, etnoecologia, educação do campo, segurança alimentar e nutricional e turismo rural, bem como as ferramentas aplicáveis à gestão do espaço rural. Busca-se, assim, contribuir para as transformações que conduzam à diversificação das atividades, à valorização dos saberes e práticas locais e ao fortalecimento dos agricultores familiares e das populações tradicionais, ações essas que fortalecem a multiculturalidade brasileira.
Unchaining Nations, Freeing People: The development challenges of the contemporary world is composed of seven chapters with a common theme: the analysis of vicious cycles that hampers the fully development of nations. Each one of the articles approaches a topic of the current international political agenda, including: civil conflicts in Sub-Saharan Africa and the case of the Central African Republic; religious sectarianism and violence in Syria; the corruption-drug trafficking nexus; press freedom; middle-income countries’ challenges on development; the relation between gender and health access; and the legal and social issues between state secularism and religious freedom.
This volume presents the proceedings of the Brazilian Congress on Biomedical Engineering (CBEB 2018). The conference was organised by the Brazilian Society on Biomedical Engineering (SBEB) and held in Armação de Buzios, Rio de Janeiro, Brazil from 21-25 October, 2018. Topics of the proceedings include these 11 tracks: • Bioengineering • Biomaterials, Tissue Engineering and Artificial Organs • Biomechanics and Rehabilitation • Biomedical Devices and Instrumentation • Biomedical Robotics, Assistive Technologies and Health Informatics • Clinical Engineering and Health Technology Assessment • Metrology, Standardization, Testing and Quality in Health • Biomedical Signal and Image Processing • Neural Engineering • Special Topics • Systems and Technologies for Therapy and Diagnosis
The Neotropical Region is one of the most diverse places in the world. In this region are found most of the lineages of bees that collect floral oils, a unique characteristic among insects. The genus Centris is an extensive group of this type of bees, which are distributed from the United States to Patagonia, in the extreme south of South America. The largest, most striking, colorful and beautiful species of the genus are found in the humid forests of South America, all of them forming part of the subgenus Centris (Melanocentris). This book brings a taxonomic review of all the species of this subgenus, including the description of numerous species hitherto unknown to science. Along with the description of these species, the new subgenus Centris (Odontoxys) is also described, which contains species that are distributed from Mexico to Argentina. The book also includes redescriptions and photographs of both sexes of all species, along with distribution maps, an identification key, and lists of material examined and of floral hosts.
Tenth in a series of annual reports comparing business regulation in 185 economies, Doing Business 2013 measures regulations affecting 11 areas of everyday business activity: starting a business, dealing with construction permits, getting electricity, registering property, getting credit, protecting investors, paying taxes, trading across borders, enforcing contracts, closing a business, and employing workers. The report updates all indicators as of June 1, 2012, ranks economies on their overall “ease of doing business”, and analyzes reforms to business regulation – identifying which economies are strengthening their business environment the most. The Doing Business reports illustrate ...
The five volume set LNCS 10960 until 10964 constitutes the refereed proceedings of the 18th International Conference on Computational Science and Its Applications, ICCSA 2018, held in Melbourne, Australia, in July 2018. Apart from the general tracks, ICCSA 2018 also includes 34 international workshops in various areas of computational sciences, ranging from computational science technologies, to specific areas of computational sciences, such as computer graphics and virtual reality. The total of 265 full papers and 10 short papers presented in the 5-volume proceedings set of ICCSA 2018, were carefully reviewed and selected from 892 submissions.
A translated, thoroughly revised, and updated edition of the German work. Part I presents the geographic distribution of seaweeds and seagrasses around the world, environmental factors, floral history, and relevant paleoceanographic considerations, covered geographically. Part II covers seaweed ecophysiology, including the relationships of light, temperature, salinity, and other abiotic factors on seaweed distribution, as well as biotic factors such as competition, herbivory, predation, and parasitism, in order to elucidate the ecophysiologic bases for the distribution patterns examined in Part I.
