This study aims to analyze the enteroparasitic occurrence in children from 0 to 12 years old consulted at the University of western São Paulo Clinical Laboratory, Presidente Prudente, SP, Brazil, in relation to the socioeconomic profile of the attended children. Stool samples were examined and a questionnaire was applied with the objective of knowing the patient's age, sex, medical attendance, characteristic of the habitation, provisioning of water, dejection and domestic waste fates, use of footwear and clinical signs. The software EPI INFO 6 (Version 6.04b) was used for the elaboration of the data bank structure and analysis after previous data codification. Among 1,000 children analyzed, as many as 21.3% presented some kind of parasite. The most frequent protozoan was Giardia lamblia (7.3%) followed by Entamoeba coli (3.9%). The most frequent helminth was Enterobius vermicularis (1.9%) followed by Hymenolepis nana (0.5%). The most frequent protozoan association was Giardia lamblia / Entamoeba coli (0.9%).

Cyclospora cayetanensis causes watery diarrhea in tropical countries, among travelers and after ingestion of contaminated water and food. Very little is known about its epidemiology, pathogenic aspects and reservoirs. In Brazil, its prevalence is unknown and to date there have been reports of three outbreaks. We report here a retrospective study of 5,015 stool samples from 4,869 patients attended at Clinical Hospital of the University of São Paulo Medical School, SP, Brazil between April 1996 and January 2002, with 14 cases of Cyclospora cayetanensis being detected there was a prevalence of 0.3%. Of the 14 infected patients, the mean age was 38 years and 71.4% were female. Ten patients presented symptoms; six presented levels of immunological markers and five patients were immunodeficient.

Cryptosporidium isolates identified in fourteen stool samples, collected from five HIV-infected patients and nine immunocompetent children, living in the Sate of São Paulo, Brazil, were submitted to a molecular analysis using a nested PCR followed of restriction fragment length polymorphism (RFLP), for genetic characterization. The analysis was based on digestion with RsaI restriction enzyme of a DNA fragment amplified from the Cryptosporidium oocyst wall protein (COWP) gene. Based on this analysis, four samples were identified as Cryptosporidium parvum, eight as Cryptosporidium hominis and two presented a profile that correspondedto Cryptosporidium meleagridis when compared to the standards used in the analysis. The use of molecular methods can be helpful to identify source of infections and risk factors related to Cryptosporidium infection in our communities.

The University of São Paulo, founded in 1934, started under the influence of important foreigners academicians in our campuses. The beginning of our university was the result of a fusion of the already existing colleges – Law School, School of Engineering, School of Pharmacy and Dentistry, College of Agriculture, Medical School, and School of Veterinary Medicine. In addition, in 1934, the School of Philosophy, Sciences and Letters was created being responsible for human sciences – Philosophy, History, Geography, Sociology – and hard sciences – Mathematics, Physics, and Chemistry – that academically amalgamated the professional existing colleges. In the thirties, we benefited from the instabilities in Europe and important professors came to the University of São Paulo contributing remarkably to our successful trajectory.[...]

CARACTERIZAÇÃO HIDRÁULICA DE GOTEJADORES AUTOCOMPENSANTES EXPOSTOS À APLICAÇÃO DINÂMICA DE CLORO LIVRE (Parte II)  Rubens Duarte Coelho1; Marconi Batista Teixeira1; Ralini Ferreira de Mélo1; Meiby Carneiro de Paula21Departamento de Engenharia Rural, Escola Superior de Agricultura Luiz de Queiroz, Universidade de São Paulo, Piracicaba, SP,  [email protected] genético e reprodução animal, IAPAR – Estação Experimental da Faz. Modelo, Ponta Grossa, PR  1 RESUMO Este trabalho teve como objetivo avaliar a caracterização hidráulica de 14 modelos de gotejadores autocompensantes, quanto ao efeito do cloro na redução de vazão, causada pela aplicação dinâmica de 100 mg L-1 de cloro livre, e o efeito linear de redução de vazão para dosagens e tempos de aplicação calculados a partir da dosagem padrão de 100 mg L-1 de cloro livre. Utilizou-se uma bancada de ensaios em estrutura metálica com 11,0 m x 4,0 m, instalada no Laboratório de Irrigação do DER– ESALQ/USP. Semanalmente, foi feita a coleta de água utilizando o método gravimétrico para todos os emissores presentes na linha gotejadora de cada um dos modelos estudados. Os modelos de gotejadores ensaiados apresentaram sensibilidade variável à aplicação de cloro livre. Ocorreu um decréscimo de 10 a 20% em média da vazão (L h-1) para a maior parte dos emissores, com exceção do modelo E que apresentou aproximadamente 90% de redução de vazão com 2688 h de funcionamento e redução drástica de vazão na ordem de 100% em virtude do bloqueio total do orifício para o emissor I. Embora o efeito da dosagem de cloro tenha sido linear, não se observaram alterações na vazão dos gotejadores com a aplicação de 10 mg L-1 de cloro livre. UNITERMOS: cloração, emissores autocompensantes, entupimento de emissores.  COELHO, R.

HYDRAULIC CHARACTERIZATION OF COMPENSATING EMITTERS EXPOSED TO FREE CHLORINE DYNAMIC APPLICATION (PART II)  2 ABSTRACT The objective of this work was to evaluate the hydraulic characterization of 14 compensating emitters regarding the effect of chlorine on the reduction of the flow rate and the linear effect of flow rate reduction at different times and dosages. The reduction of the flow rate was caused by the dynamic application of 100 mg L-1 of free chlorine. The experiment was carried out under laboratory conditions in a metal bench (11.0 m x 4,.0 m) at the University of São Paulo Brazil. Emitter flow was evaluated weekly using the gravimetric method. The studied emitter models presented varying sensitivity to the application of free chlorine. An average reduction of 10 to 20% in the flow rate (L h-1) for most   emitters was observed. The “E” model presented a reduction of 90% in the flow rate over 2,688 operation hours. The “I” model presented a sharp reduction of flow rate on the order of 100% (total clogging). Although the linear effect of chlorine dosage was present in all models, changes in the flow rate among the emitters during chlorine application of 10 mg L-1 were not observed. KEY WORDS: chlorination, compensating emitters, emitter clogging.

Resumo O entendimento das causas e as principais razões que influenciam o modo como os pesquisadores se articulam e constroem suas redes de colaboração científica ainda é uma questão em aberto na pesquisa acadêmica. De fundamental importância para o desenvolvimento de novos indicadores e modos de avaliação da produção científica, o conceito de redes sociais permite operar novos planos de análise, contribuindo com seus aspectos estruturais e dinâmicos ao estudo dos mecanismos e gatilhos causais que levam à constituição dessas redes de colaboração científica. A obtenção de atributos individuais dos pesquisadores, de dados de constituição das redes ao longo do tempo e o modo de desambiguação dos nomes que compõem essas redes de colaboração têm se mostrado os principais desafios de estudos das redes. O objetivo deste artigo é descrever como concebemos uma maneira de estudar as redes de colaboração de uma universidade, com foco específico na Universidade de São Paulo, identificando suas principais estratégias de conectividade e mecanismos causais, além de encontrar as relações entre suas redes e diferentes níveis de produtividade científica de seus participantes. Vale frisar que o artigo apenas descreve as questões da pesquisa e o modo de tratá-las, ficando sua execução para os próximos passos deste trabalho de pesquisa. Para tanto, pretende utilizar como base de análise uma Biblioteca de Produção Científica Institucional em desenvolvimento pelo SiBi/USP, que coleta os artigos publicados por membros da universidade em bases de dados de indexação de revistas nacionais e internacionais, tais como Scielo, Web of Science e BioMed, além da utilização da base de dados institucional para obtenção dos atributos individuais dos pesquisadores participantes dessas redes de colaboração.Palavras-chave análise de redes sociais, indicadores, cientometria, modelos causais.Abstract The understanding of the causes that influence how researchers articulate and build their scientific collaboration networks is still an open question in academic research. Of fundamental importance for the development of new indicators and methods of evaluation of scientific literature, the concept of social networking helps operate new levels of analysis, contributing their structural and dynamic aspects to the study of causal mechanisms and triggers that lead to the formation of these networks of scientific collaboration. Obtaining attributes of individual researchers, data on the constitution of networks over time and mode of disambiguation of the names that make up these collaboration networks have been the main challenges in the area of research networks. The purpose of this article is to describe how we designed a way to study a university’s collaboration networks, focusing on the University of São Paulo, and identifying their key strategies, connectivity and causal mechanisms, as well as finding links between their networks and different levels of participants’ productivity. It should be noted that this article only describes the research questions and how to treat them, leaving their implementation to the next steps of this research. The database used for analysis was the Institutional Scientific Production being developed by Sibi/USP, which collects articles published by members of the university indexed in national and international databases such as Scielo, Web of Science and BioMed, as well as an institutional database to obtain the individual attributes of the researchers participating in these networks.Keywords social network analysis, indicators, scientometrics, causal model

Teacher training in higher education has been relatively neglected in Brazilian universities because postgraduate programs are mainly focused on the research that students produce. However, these postgraduate students are expected to become the next university and college professors. Herein, we present the experience of the Zoology Summer Course, a university extension course organized by graduate students from the Zoology Graduate Program at the University of São Paulo, Brazil. This course was created aimed to provide graduate students with an opportunity to develop and practice their teaching skills. To understand the influences, motives, and legacy of the CVZOO on its organizers, we developed a questionnaire and evaluated the responses by focusing on elements of academic formation and prospects for a teaching career, using systematic content analysis procedures as parameters. Our results demonstrate the importance of CVZOO as a space of dialogue and interaction for professional teacher training, as well as an opportunity to exchange experiences and build professional identity. The course has also influenced other academic activities such as the organization of scientific events, mentoring experience, and publications. Lastly, we discuss the importance of teacher training in Brazilian graduate programs and propose initiatives to improve the training of future university teachers.
