O livro Geografia em Foco: Teorias e Práticas traz uma coletânea de artigos científicos com reflexões teóricas e, também, estudos de casos e experiências pedagógicas sobre uma grande diversidade de temas dentro da ciência geográfica. Esta obra surge a partir da necessidade de oportunizar que o conhecimento elaborado por diversos pesquisadores do Brasil possa alcançar não somente a comunidade acadêmica, mas também todos aqueles que se interessem pelas discussões que permeiam o espaço geográfico. Assim, por meio da variabilidade temática e metodológica da Geografia esta obra aponta perspectivas no âmbito educacional, econômico, ambiental, cultural e social.
A arborização urbana exerce um papel fundamental para o bem-estar social e qualidade de vida da população. Além de fornecer conforto térmico, vários serviços ecossistêmicos que interferem diretamente na vida da sociedade são maximizados pela presença de áreas verdes. Os espaços com árvores minimizam vários dos impactos ambientais do crescimento urbano, trazendo melhorias econômicas, ambientais, sociais, culturais e para a saúde humana. Em relação ao aspecto ambiental, as árvores plantadas podem absorver o calor envolvente, diminuindo assim a temperatura local. Em termos sociais, as vantagens são o conforto de pedestres e motoristas, além de gerar benefícios econômicos...
Diante da importância e da intensificação da degradação dos recursos hídricos, é fundamental identificar o modo como as pessoas os percebem. Nesse sentido, o presente livro traz resultados de uma investigação minuciosa sobre como esses recursos são percebidos por estudantes do ensino médio, oriundos de distintas instituições de ensino do Estado de Goiás, bem como seus conhecimentos sobre a temática. A partir da interpretação de distintas charges pelos estudantes, evidenciamos que suas percepções foram pouco abrangentes e que seus conhecimentos acerca de aspectos ligados aos recursos hídricos são superficiais. Nesta obra também será possível contemplar uma avaliação dos conteúdos referentes à temática "recursos hídricos" presentes em livros didáticos de Biologia do ensino médio.
This is the third edition of this manual which contains updated practical guidance on biosafety techniques in laboratories at all levels. It is organised into nine sections and issues covered include: microbiological risk assessment; lab design and facilities; biosecurity concepts; safety equipment; contingency planning; disinfection and sterilisation; the transport of infectious substances; biosafety and the safe use of recombinant DNA technology; chemical, fire and electrical safety aspects; safety organisation and training programmes; and the safety checklist.
Micro(nano)plastics in the Aquatic Environment: Fate, Toxicology, and Management Volume 11 explores a wide breadth of chapters, reflecting the experiences of groups of researchers from different countries on essential aspects of the context of plastic pollution. The book provides insights in chapters relating to plastic pollution in the aquatic ecosystems, the behavior of MNPs in the aquatic environment and influencing factors, characteristics of MNPs in the water environment, ecology and MPs, metals and MPs, biofilms and MPs, MNPs pollution in the global mangrove ecosystem, ecotoxicity MPs in amphibian, fishes and snails, and MPs in mariculture.
A comprehensive reference for assessing the antioxidant potential of foods and essential techniques for developing healthy food products Measurement of Antioxidant Activity and Capacity offers a much-needed resource for assessing the antioxidant potential of food and includes proven approaches for creating healthy food products. With contributions from world-class experts in the field, the text presents the general mechanisms underlying the various assessments, the types of molecules detected, and the key advantages and disadvantages of each method. Both thermodynamic (i.e. efficiency of scavenging reactive species) and kinetic (i.e. rates of hydrogen atom or electron transfer reactions) asp...
For most Western audiences, Cuba is a touristic paradise stuck in time and virtually detached from world technology networks by the US embargo – anything but a hub of industrial innovation and high value-added biotechnology. However, a closer look reveals more subtle but equally powerful stories that challenge the homogenizing assumptions of conventional economics and open up scope for more sophisticated reflections on Cuban economy and industry. From this kind of enquiry emerges the case of the internationally respected Cuban biotech industry as the most successful case of science and technology policy in the country’s economic history. The book takes an interdisciplinary approach, exploring issues such as interdependency, purpose and history as natural constituencies of the innovation process. It also examines the dynamic and crucial role played by the state in the formation of innovative business enterprises. This book will be of interest to academic researchers in the fields of innovation and economic development.
At first glance, studying behavior is easy, but as every budding ethologist quickly realises, there are a host of complex practical, methodological and analytical problems to solve before designing and conducting the study. How do you choose which species or which behavior to study? What equipment will you need to observe and record behavior successfully? How do you record data in the dark, in the wet, or without missing part of the action? How do you analyse and interpret the data to yield meaningful information? This new expanded edition of the Handbook of Ethological Methods provides a complete step-by-step introduction to ethological methods from topic choice and behavioral description to data collection and statistical analysis. This book will be a must for beginning students and experienced researchers studying animal behavior in the field or laboratory.
