Abstract: Nous d\'ecrivons les singularit\'es de feuilletages holomorphes dicritiques de petite multiplicit\'e en dimension $3$. En particulier nous relions l'existence de d\'eformations et de d\'eploiements non triviaux \`a des probl\`emes d'int\'egrabilit\'e liouvillienne. We describe the singularities of dicritical holomorphic foliations of small multiplicity in dimension $3$. In particular we connect the existence of non trivial deformations and deployments to problems of liouvillian integrability.

Abstract: colorectal neoplasm is one of the most common cancers in developed countries and its incidence has grown progressively. the currently used attempts to prognostic assessment are limited, since they are restricted to the observation of tumor morphology, such as the tnm staging. the quantification of free dna in peripheral blood aims to find a way to relate it to the clinical status of patients with cancer. objective: to evaluate the prognosis of patients with colorectal cancer with the quantification of alu247 fragments in peripheral blood and tnm staging. methods: we evaluated 79 patients in the following groups: operated, and non-operated and control as to the alu247 fragment dosage and its correlation with tumor staging. results: the amount of alu247 fragments revealed very different results when comparing the different groups. the mean quantity in the non-operated group was 14.62 pg, while the mean was 0.48 pg for the control group and 0.93 pg for the operated group. serum levels of alu247 were higher in more advanced morphofunctional classes of the tnm staging. conclusions: we suggest there is a relation between the advanced tnm stage and high doses of free dna in peripheral blood with worse prognosis.

Abstract: the objective of this work was to estimate the coefficient of repeatability for production of fruits and solid albumen in coconut palm (cocos nucifera) using statistical methods of the variance analysis (anova), main components (covariance and correlation) and structural analysis (covariance). significant variability was detected between hybrids for fruits and solid albumen productions. repeatability coeficients obtained by the variance analysis and structural analysis (correlation) showed the smallest values. if the level of 90% is considered sufficient to select hybrids with relative superiority for fruit and solid albumen productions based on the estimation of repeatability by the main components method (covariance), then it would be recommended to perform five and three evaluations for fruit and solid albumen productions, respectively.

Abstract: INTRODU O: O presente trabalho analisou 150 casos consecutivos de tratamento da hidrocefalia com DVP no Hospital das Clínicas de Ribeir o Preto entre mar o de 1997 e julho de 2000. OBJETIVO: Tra ar as principais características dos pacientes e dos procedimentos, com ênfase nas etiologias, diagnóstico, complica es, seqüelas e fatores associados. MéTODOS: Prontuários médicos como fonte para quantificar as variáveis selecionadas. RESULTADOS: As etiologias congênitas e adquiridas tiveram a mesma incidência, destacando-se a mielomeningocele no primeiro grupo e a prematuridade e a meningite no segundo. As principais complica es foram o mal funcionamento da válvula (33%) e a infec o (15%). Incluídas as cirurgias devido às complica es, houve 2,5 procedimentos por paciente em média. No último retorno, 40% dos pacientes apresentavam algum grau de retardo do desenvolvimento neuro-psico-motor (RDNPM). As principais etiologias relacionadas a RDNPM foram prematuridade, meningite e malforma es complexas. Discuss o: O trabalho serviu como ferramenta para ajudar a caracterizar a história natural da hidrocefalia e de seu tratamento em nosso meio, fornecendo base para uma melhor compreens o da mesma e para compara o com a literatura e com outros servi os. A taxa de RDNPM está condizente com a literatura. A taxa de infec o está mais elevada, podendo haver rela o com o fato de ser este um hospital-escola. Maior tempo de seguimento seria necessário para compara o da incidência de complica es mecanicas.
