This study focuses on the presence of radon (Rn-222) and volatile organic compounds (VOCs) in soil gases at a gas station located in the city of Rio Claro, Sao Paulo, Brazil, where a fossil fuel leak occurred. The spatial distribution results show a correlation between Rn-222 and VOCs, consistent with the fact that radon gas has a greater chemical affinity with organic phases than with water. This finding demonstrates that the presence of a residual hydrocarbon phase in an aquifer can retain radon, leading to a reduced radon content in the soil gas. The data in this study confirm the results of previous investigations, in which the method used in this study provided a preliminary fingerprint of a contaminated area. Furthermore, the data analysis time is brief, and only simple equipment is required. (C) 2014 Published by Elsevier Ltd.

This research focuses on methods and strategies for educational-based digital tools, aimed at the public school. Thus, we present possibilities, and the main actions of the national museum institutions in several online educational services that exemplify some forms of virtual mediation in order to verify the relevance of using these tools. The study discusses the need for museums to follow the advance of new technologies to engage and retain the public school, consisting of a highly connected generation with new technologies. It also brings a brief overview of the evolution of the museum in the Western world and presents the formation and nature of art collections that comprise the Artistic-Cultural Collection of the Governmental Palaces of the State of São Paulo, focusing on the management policy of each period, highlighting the educational program and the relationship with the website. As a practical exercise, the research presented suggests applying a form of mediation for the virtual site of Artistic-Cultural Collection of the Governmental Palaces to extend relations sector educational institution for the virtual context

On November 26 th, 2005, Rhea, one of Saturn's moons, is found by Cassini spacecraft approximately at 5.105 km from Saturn. Observations in situ reveal that electrons are depleted in the moon's vicinity. However, Rhea is considered massive enough to retain a thin atmosphere. Assumption was that the atmosphere of Rhea was not composed exclusively of gas, its likely contains solid material that can absorb magnetospheric particles. According to Jones et al. (2008), these particles were in a speci c position so that at the moment of observation the electrons could not be detected. In opposition to this idea there is a group, Tiscareno et al. 2010, Cornell University Library, that underwent intensive search for any material that might be orbiting Rhea using Cassini images, however the could not identify any. Second recommendation made by American researchers and other countries, and accepted by the National Board of Research the Cassini Equinox Mission will continue in orbit around Saturn until 2016.The probe will perform several maneuvers with high inclination to delve into the main ring system, and then enter in Saturn's atmosphere and collide with planet. This research is of great importance because until today no rings were found orbiting satellites. The goal of this work is to analyze the orbital evolution of a set of particles around Rhea disturbance of Saturn, J2 e J4 and check results by the numerical simulations and the possibility of a stable ring orbiting Rhea.

In the present study aimed to study the use of radio and television in Brazil by the various Christian aspects rooted in the country. The main objective was to analyze how the churches define the orientation or the use of strategies of both comprehensive and traditional media vehicles, which are still the most popular mass media, both for the formation of culture and national public opinion in both states and municipalities, which demarcate and retain regional traits that differentiate culturally, economically and socially diverse Brazilian populations. Christian churches are increasingly seeking loopholes and legal facilities, public spaces and broadcast media to facilitate the achievement of followers of their theological ideologies. On the radio, on television and also through social networks of the Internet, pastors, priests, bishops and lay Christians to seek their potential both in public space and home individually, using old and new individual devices and portable reception of audiovisual content. All preachers fiercely competing for space leased the open television networks, in national and local radio stations and invest in the organization of broadcasters Community legalized or informal. The work also aims to study the radio and television concessions in Bauru, to show the failures that occur in broadcasting spectrum management by the federal government and also for the reader to understand what the Constitution says about the use of these vehicles public concession by religious institutions

In Brazil, Eucalyptus grandis Hill ex Maiden is widely used for commercial reforestation, especially for production of pulp, paper and energy. Its genetic variability is being explored in tree improvement programs for over 30 years. The objective of this work was to estimate genetic parameters and compare genetic gains by multi-effects index in a breeding population of E. grandis. Progeny tests were established using open-pollinated seeds from ten provenances ranging from 153 to 160 progenies established in a completely randomized block design in four sites of Sao Paulo State (Anhembi, Avere Itarare e Pratania). At 24 months of age the traits diameter at breast height (DBH), height (ALT) and volume (VOL) were measured. The individual site analyses indicated significant genetic differences among progenies, height genetic variability and the mean progeny heritability (> 0.70). For joint analyses of sites, significant differences in genotype x environmental interaction effects were detected, showing differences of performance of the progenies in different sites. The Itarare site gave high genetic gains, effective size and genetic diversity. The genetic diversity and low effective size are unviable factors; considering that the progeny tests studied should retain adequate levels of genetic variability in order to be transformed in future seedling seed orchards.

Aim: The aim of this report is to describe a quick and simple method of positioning retention magnets when deformed patients are rehabilitated with an oculopalpebral prostheses attached to a maxillary denture/obturator. Background: In patients with deformities requiring complex rehabilitations, the use of magnets is the most efficient means of providing combined prostheses with retention quality and stability. Usually prostheses with magnets are in sections and have a magnet in each section. When the sections are put together properly, the magnets are attracted to each other and retain the sections. Report: An edentulous patient presented for a post-surgical evaluation of a maxillofacial prosthesis used to repair a partial maxillectomy and left orbital exoneration which removed all adjacent tissues leaving an open communication between the oral, nasal, and orbital cavities. The proposed treatment plan included construction of a maxillary complete denture with a palatal obturator and a mandibular complete denture. Magnets were used to attach the oculopalpebral prosthesis to the maxillary denture/obturator. Summary: Use of retention magnets simplify the clinical and laboratorial phase, retains the denture, and makes it stable and comfortable for the patient. This treatment is one successful approach to the restoration of oral function and increases the patient’s quality of life.
