Algebraic topology from a homotopical viewpoint by M. A Aguilar ( )
16 editions published between 1899 and 2011 in English and held by 668 WorldCat member libraries worldwide
"The purpose of this book is to introduce algebraic topology using the novel approach of homotopy theory, an approach with clear applications in algebraic geometry as understood by Lawson and Voevodsky. This method allows the authors to cover the material more efficiently than the more common method using homological algebra. The basic concepts of homotopy theory, such as fibrations and cofibrations, are used to construct singular homology and cohomology, as well as K-theory. Throughout the text many other fundamental concepts are introduced, including the construction of the characteristic classes of vector bundles. Although functors appear constantly throughout the book, no previous knowledge about category theory is expected from the reader. This book is intended for advanced undergraduate and graduate students with a basic background in point set topology as well as group theory and can be used in a two-semester course."--Jacket

Trapping Triatominae in silvatic habitats by Francoise Noireau ( )
2 editions published in 2002 in English and held by 3 WorldCat member libraries worldwide
Large-scale trials of a trapping system designed to collect silvatic Triatominae are reported. Live-baited adhesive traps were tested in various ecosystems and different triatomine habitats (arboreal and terrestrial). The trials were always successful, with a rate of positive habitats generally over 20 percent and reaching 48.4 percent for palm trees of the Amazon basin. Eleven species of Triatominae belonging to the three genera of public health importance (Triatoma, Rhodnius and Panstrongylus) were captured. This trapping system provides an effective way to detect the presence of triatomines in terrestrial and arboreal silvatic habitats and represents a promising tool for ecological studies. Various lines of research are contemplated to improve the performance of this trapping system (AU)

Consumo de sustancias toxicas y tabaco entre la poblacion estudantil de 14 a 18 anos by E Castro Sariana ( )
1 edition published in 1982 in Spanish and held by 1 WorldCat member library worldwide
En este estudio se presentan los resultados obtenidos en una investigacion sobre el consumo de sustancias toxicas entre la poblacion estudiantil de 14 a 18 anos del area metropolitana de Mexico, D.F.; se investigo el consumo de 12 sustancias toxicas, incluidos el alcohol y el tabaco, asi como los problemas asociados a su consumo. La muestra estuvo constituida por un total de 3.408 estudiantes pertenecientes a 89 escuelas, que fueron seleccionadas mediante un diseno estratificado. Los resultados mas importantes fueron los siguientes: no hay cambios significativos en comparacion con una encuesta de 1978, con excepcion del tabaco, que disminuyo alrededor de 6.3% en la categoria de consumo ocasional y las anfetaminas que tienden a aumentar 1.1%. El uso de solventes, antes privativo de estudiaantes de escuelas de nivel economico bajo o marginado, ahora se extiende a todas las zonas socioeconomicas El procentaje de estudiantes que manifiesta haber tenido problemas legales a causa de su consumo de drogas aumento significativamente entre dos encuestas, una en 1978 y otra en 1980. Las sustancias de mayor consumo fueron en orden de importancia, el alcohol, el tabaco, los inhalables, las anfetaminas y la marijuana

Gerador de funções com microprocessador 8085 e interface digital/analógica by M. A Aguilar ( )
1 edition published in 1984 in Portuguese and held by 1 WorldCat member library worldwide
Foi desenvolvido "software" com o objetivo especifico de gerar sinais, tais como triangular, senoidal, quadrada, trapezoidal, dente de serra e pulsos. Esses sinais podem apresentar variacoes de frequencia e de amplitude, definidas pelo usuario. Foi utilizada a porta 22H do circuito integrado 8155 (PPI) e por essa razao houve a necessidade de programa-lo inicialmente como porta de saida. A interface digital/analogica e constituida por dois circuitos integrados SN74LS08, uma malha de resistores R-2R e dois amplificadores operacionais BIMOS CA3140 de alto slewrate e impedancia de entrada da ordem de 1 T ohm. Os circuitos integrados SN74LS08 foram utilizados como chaves entre a porta 22H do 8155 (PPI) e a entrada do conversor digital/analogico. Essas chaves desemp
