A.de AZEVEDO FILHO and published by . This book was released on 1992 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Procurou se conhecer a potencialidade de algumas cultivares de feijao (Phaseolus vulgaris L.) para o melhoramento visando a tolerancia as condicoes quimicas dos solos acidos de baixa fertilidade e identificar a(s) populacaoes segregante(s) mais promissora(s) para a selecao de progenies adaptadas a estas condicoes de cultivo. Para isto sete cultivares de feijao, diferindo quanto a tolerancia as condicoes quimicas dos solos acidos e outros atributos, foram intercruzadas em esquema dialelico completo. As 21 populacoes e os sete parentais foram avaliados no campo nas geracoes F2 e F3. Em cada geracao, conduziu-se dois experimentos no delineamento blocos casualizados, com tres repeticoes, nos niveis de 4 e 26% de saturacao do aluminio. Foram obtidos dados da producao de graos (kg/ha) e producao de biomassa (peso seco da parte aerea + peso seco da raiz). Os efeitos de capacidade geral de combinacao (CGC) e capacidade especifica de combinacao (CEC) foram obtidas conforme metodo 4/modelo I de GRIFFING (1956). Constatou-se diferenca entre os progenitores com relacao a tolerancia as condicoes prevalecentes dos solos acidos de baixa fertilidade, evidenciando em mais essa oportunidade variabilidade genetica para a tolerancia ao aluminio toxico. Foi evidenciado que o controle genetico da producao de graos tanto na maior como na menor saturacao de aluminio foi predominantemente aditivo, embora fosse detectada significancia para capacidade especifica de combinacao que mostra tambem a ocorrencia de pais; (...).

Available in PDF, EPUB and Kindle. Book excerpt: There is widespread consensus in the international scientific community that climate change is happening and that abrupt and irreversible impacts are already set in motion. What part does education have to play in helping alleviate rampant climate change and in mitigating its worst effects? In this volume, contributors review and reflect upon social learning from and within their fields of educational expertise in response to the concerns over climate change. They address the contributions the field is currently making to help preempt and mitigate the environmental and social impacts of climate change, as well as how it will continue to respond to the ever changing climate situation. With a special foreword by Desmond Tutu, Archbishop Emeritus of Cape Town.

Hoch through to Timothy Beatley; Jonathan Barnett, Alex Garvin, Tom Daniels, Andres Duany and Barbara Faga. The variety and wide selection of readings offers one of the most innovative amalgamations of planning research and practice. The Reader lays out the context, range of concerns, history, methods and key topics for twenty-first century urban and regional planning. Sections on the world of planning, history and theory, classic readings, practice and current issues include writings with a focus on the distribution of space and place, essays on housing, transportation design, environment, community development, the effects of cultural diversity and information technology on land use and other topics. It displays the techniques used to direct and control growth, including zoning, master planning, public budgeting and citizen participation. It explores different types of plans distinguished by their scale and reference type. It references analytical and presentation techniques and outlines ethical issues confronting planners. This Urban and Regional Planning Reader provides an essential resource, for students of planning, drawing together important but widely dispersed writings and the associated bibliography is a resource which enables deeper investigations. The synthesis is also valuable for lecturers and researches in the area and the pertinent editorial commentaries preceding each entry not only demonstrate its significance, but also outline the issue surrounding the topic.
