1. Decaimento dos autovalores de operadores integrais positivos gerados por núcleos Laplace-Beltrami diferenciáveis / Eigenvalue decay of positive integral operators generated by Laplace-Beltrami differentiable kernels
Neste trabalho obtemos taxas de decaimento para autovalores e valores singulares de operadores integrais gerados por núcleos de quadrado integrável sobre a esfera unitária em \ R POT. m+1\ , m 2, sob hipóteses sobre ambos, certas derivadas do núcleo e o operador integral gerado por tais derivadas. Este tipo de problema é comum na literatura, mas as hip

2. Números de Lê e classes de Milnor de hipersuperfícies analíticas complexas / Lê numbers and Milor classes of complex analytic hypersurfaces
Este trabalho está dividido em duas partes distintas. Na primeira parte caracterizamos os números de Lê de polinômios que são rodutos de polinômios de Pham-Brieskorn de mesmo tipo, que denominamos de arranjos de Pham-Brieskorn, obtendo fórmulas para estes números somente utilizando o número de variáveis, os pesos e o grau de homogeneidade destes po

5. Auxin Transport Synchronizes the Pattern of Cell Division in a Tobacco Cell Line1
The open morphogenesis of plants requires coordination of patterning by intercellular signals. The tobacco (Nicotiana tabacum cv Virginia Bright Italia) cell line VBI-0 provides a simple model system to study the role of intercellular communication in patterning. In this cell line, singular cells divide axially to produce linear cell files of distinct polari

6. Functional domains are specified to single-cell resolution in a Drosophila epithelium
Specification of pattern is fundamental to the development of a multicellular organism. The Malpighian (renal) tubule of Drosophila melanogaster is a simple epithelium that proliferates under the direction of a single tip cell into three morphologically distinct domains. However, systematic analysis of a panel of over 700 P{GAL4} enhancer trap lines reveals

7. Birth season glucocorticoids are related to the presence of infants in sifaka (Propithecus verreauxi)
The responses of plural breeding mammals to environmental stressors are little understood in free-ranging populations, but recent studies of singular breeders suggest that ecological factors and social milieu influence the variable physiological stress responses observed among individuals. Our previous studies examining faecal glucocorticoid (fGC)–behaviou
