O grupo escolar de São Luiz do Paraitinga: contexto histórico (décadas de 1930 a 1970)

The present work has as its theme the group of St. Louis School of Paraitinga: historical context (the 1930 to 1970). This work has the distinction the subject rarely addressed in academic, school groups in the region of Vale do Paraiba, these schools are not constant theme of research, making this differentiation materials present little used, but extremely important for understanding of education present in the region of Vale do Paraíba. For the realization was made to read the legislation in the period 1930 to 1970, the documentation provided by the Department of Education, reading and analysis of documentation presented, one can understand the historical context of the school group to be targeted by the study: School Group Colonel Domingues de Castro. Objective of this study was to understand how the group of the school of St. Louis was shaping up Paraitinga laws and guidelines in the historical context of the decades from 1930 to 1970, contextualizing historical events general and the specific events of São Luiz do Paraitinga. The methodology used is studies of educational phenomena along with the narrative-biographical study of respondents to this survey

Avaliação comparativa in vivo da eficácia do óleo de melaleuca, clorexidina e listerine sobre streptococcus mutans e microrganismos totais na saliva

Objective: To compare the efficacy of the mouthwashes 0.12% chlorhexidine, Listerine, and 0.5% and 2% Melaleuca Alternifolia oil against the salivary levels of Streptococcus mutans and total microorganisms. Methods: This study was double-blind controlled and paired clinical assay. Twenty-six volunteers aged 21 to 35 years old were enrolled. At baseline, 1 mL of unstimulated saliva was collected from each subject, 1 and 15 min after mouthrinsing with the following solutions: sterile distilled water, 0.12% chlorhexidine digluconate, Listerine (©Johnson & Johnson do Brasil), 0.5% and 2% concentrations of Melaleuca Alternifolia (Sigma-Aldrich). The volunteers used all the evaluated mouthrinses with a 15-day interval between the solutions. Immediately after rinsing, saliva was collected and serial dilutions were performed, followed by plating in blood agar culture medium for growth of total microorganisms and SB-20 (Sucrose-Bacitracin agar) for growth of S. mutans, and incubation at 37 °C for 48 h in microaerophilia. After incubation, the number of colonies was counted and expressed as colony forming units (UFC/mL). Results: Chlorhexidine showed antimicrobial action by reducing total microorganisms and S. mutans, while the action of 0.5% Melaleuca Alternifolia was similar to that of distilled water. Listerine and 2% Melaleuca Alternifolia oil reduced total microbial counts by 11% and 9% respectively, and S. mutans by 20% and 11%. Conclusion: A single rinse with 0.12% chlorhexidine is effective in reducing the levels of total microorganisms and S. mutans present in saliva. Under the same testing conditions, Listerine and 0.5% and 2% Melaleuca Alternifolia oil presented lower efficacy than chlorhexidine.

Book Review of Laud Humphreys: Prophet of Homosexuality and Sociology by John F. Galliher, Wayne H. Brekhus, and David P. Keys

As an undergraduate sociology major, the only thing I learned about Oklahoman Laud Humphreys's classic, Tearoom Trade (1970) was how it violated standards of informed consent in social science research. As Galliher, Brekhus, and Keys recount in their biography, Laud Humphreys: Prophet of Homosexuality and Sociology, sociology graduate student Laud Humphreys needed to supplement his (quite likely, participant) observational research of men who had sex in public bathrooms (i.e., tearooms) in St. Louis in the mid-1960s with a formal questionnaire. Knowing that these men would never agree if they knew they were selected because of their participation in highly stigmatized and criminal behavior, Humphreys recorded their license plates, got their home addresses, and interviewed them as part of a "community health survey." Herein lies the deception and the major source of the controversy. What I didn't fully appreciate when I was a student, however, and what the authors so deftly illuminate is the importance of this work not only for debates around ethical issues of social science research, but more importantly, perhaps, for the study of sexuality, deviance, and urban life.

Radiation balance at the surface in the city of So Paulo, Brazil: diurnal and seasonal variations

The main goal of this work is to describe the diurnal and seasonal variations of the radiation balance components at the surface in the city of So Paulo based on observations carried out during 2004. Monthly average hourly values indicate that the amplitudes of the diurnal cycles of net radiation (Q*), downwelling and upwelling shortwave radiation (SW(DW), SW(UP)), and longwave radiations (LW(DW), LW(UP)) in February were, respectively, 37%, 14%, 19%, 11%, and 5% larger than they were in August. The monthly average daily values indicate a variation of 60% for Q*, with a minimum in June and a maximum in December; 45% for SW(DW), with a minimum in May and a maximum in September; 50% for SW(UP), with a minimum in June and a maximum in September; 13% for LW(DW), with a minimum in July and a maximum in January; and 9% for LW(UP), with a minimum in July and a maximum in February. It was verified that the atmospheric broadband transmissivity varied from 0.36 to 0.57; the effective albedo of the surface varied from 0.08 to 0.10; and the atmospheric effective emissivity varied from 0.79 to 0.92. The surface effective emissivity remained approximately constant and equal to 0.96. The albedo and surface effective emissivity for So Paulo agreed with those reported for urban areas in Europe and North America cities. This indicates that material and geometric effects on albedo and surface emissivity in So Paulo are similar to ones observed in typical middle latitudes cities. On the other hand, it was found that So Paulo city induces an urban heat island with daytime maximum intensity varying from 2.6A degrees C in July (16:00 LT) to 5.5A degrees C in September (15:00 LT). The analysis of the radiometric properties carried out here indicate that this daytime maximum is a primary response to the seasonal variation of daily values of net solar radiation at the surface.

MICROSATELLITE LOCI FOR TUCUMA OF AMAZONAS (ASTROCARYUM ACULEATUM) AND AMPLIFICATION IN OTHER ARECACEAE

Premise of the study: Microsatellite loci were developed for tucuma of Amazonas (Astrocaryum aculeatum), and cross-species amplification was performed in six other Arecaceae, to investigate genetic diversity and population structure and to provide support for natural populations management. Methods and Results: Fourteen microsatellite loci were isolated from a microsatellite-enriched genomic library and used to characterize two wild populations of tucuma of Amazonas (Manaus and Manicore cities). The investigated loci displayed high polymorphism for both A. aculeatum populations, with a mean observed heterozygosity of 0.498. Amplification rates ranging from 50% to 93% were found for four Astrocaryum species and two additional species of Arecaceae. Conclusions: The information derived from the microsatellite markers developed here provides significant gains in conserved allelic richness and supports the implementation of several molecular breeding strategies for the Amazonian tucuma.
