Taschenbuch. Condición: Neu. Neuware -This book aims to evaluate the process of immobilising Candida antarctica B (CAL B) lipase in flexible polyurethane. The enzyme polymerisation process was carried out by mixing monomers, surfactants, chain extenders and water. The immobilisation technique, as well as the stability of the immobilised enzyme at different temperatures and the capacity for reaction cycles, were evaluated by the synthesis activity of oleic acid and ethanol. In order to optimise the process of measuring the esterification activity of immobilised D30 and D18, a central composite rotational design (CCRD) was performed using enzyme concentration and reaction temperature as variables. The results of continuous recycling demonstrated the possibility of reusing immobilised D30 and D18 up to 5 times, considering 50% residual activity. The results of the recycling carried out every 24 hours and with washing in organic solvents showed reuse up to 15 times for both immobilised enzymes (D30 and D18). Regarding the thermal stability of the immobilised enzymes, the results were superior to those presented by free Candida antactica B lipase. 68 pp. Englisch.…

Tapa Blanda. Condición: New. Apresenta reflexões sobre os fundamentos e práticas de uma Educação Integral, na perspectiva da Educação Cidadã. Os autores sugerem mudanças nas práticas educativas atuais e apresentam sugestões de como fazê-lo, o que inclui ações no âmbito das unidades educacionais e de outros espaços da comunidade que são potencialmente educativos. Nessa perspectiva, o município ocupa centralidade no ato de educar, pois ampliam-se as possibilidades de fortalecimento da cultura local, à medida que a escola consegue mapear e analisar as necessidades de aprendizagens das crianças e dos adolescentes e, com eles, identificar os espaços potencialmente educacionais que contribuem com a realização de processos educativos mais plenos e integrais. Aqui os autores defendem o resgate do sentido do trabalho docente na era da informação e propõem que a escola se transforme em gestora social do conhecimento que se constrói na comunidade e no âmbito da municipalidade. 123 Páginas. 160 gr.

Condición: Nuevo. O Pequeno Martim está dentro da história e quer sair de lá, porque se sente preso. Para isso, o Martim pede ajuda a meio mundo: a um gafanhoto saltitão, a um avião de papel, a um balão, a uma garrafa, a uma tartaruga a uma baleia, a um ET, e a muitos outros. Será que o Martin vai encontrar quem o liberte da história? Provavelmente sim! Quem será? E como vai o Martim sair da história? Terás de ler o livro para descobrir tudo isto (e muito mais). Oscar Sánchez Requena (ilustrador).…

Hardcover. Condición: new. Hardcover. Latin America represents about 10% of the global population distributed in 33 countries. There is huge social and economic heterogeneity even within and beyond the same country, particularly Brazil being the largest country, where Portuguese is the official language rather than Spanish. Furthermore, several ranking systems have considered Brazil a unique country within the 10 world highest economies. In view of the diversity in Latin America with different possibilities and realities we have found it essential to develop a textbook with focus on the Management of Cancer in Latin America, describing our daily reality, problems to overcome and our huge possibilities. In this volume, we discuss various cancers from melanoma to cost-effectiveness. We hope that this book will serve as a valuable resource of information for health care professionals, practitioners and policy makers. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.…
