Fluoride in the groundwater of the Tubarao and Crystaline aquifers, Salto-Indaiatuba region (SP)

Anomalous concentrations of fluoride in groundwater were identified in 19 drilling wells in the Salto-Indaiatuba region, Sao Paulo State, with an average concentration of 3.03 mg dm(-3) and a maximum of 6.95 mg dm(-3), which constitute a restriction for the water`s usage in terms of human consumption. The wells exploit water from the Tubarao Aquifer (sedimentary, granular) and Crystalline Aquifer (granitic, fractured), used for sanitary or industrial purposes. These groundwaters are typically HCO(3) and HCO(3)-SO(4) types, with high concentrations of HCO(3) -and Na(+) and high pH-values between 7.5 and 10.0. The highest concentrations of F-are associated to the Tubarao and Tubarao/Crystalline aquifer drilling wells. The presence of F-in groundwater is controlled by these high pH-values, alkalinity, and fluorine availability. The source of fluoride in the Tubarao and Crystalline Aquifers can be related to the percolation of hydrothermal fluids associated with Mesozoic lava flow, emplaced due to the opening of Atlantic Ocean and/or hydrolysis of fluorine-rich minerals and clay minerals.

Picosecond Dynamics of Proton Transfer of a 7-Hydroxyflavylium Salt in Aqueous-Organic Solvent Mixtures

The intermediacy of the geminate base proton pair (A*center dot center dot center dot H(+)) in excited-state proton-transfer (ESPT) reactions (two-step mechanism) has been investigated employing the synthetic flavylium salt 7-hydroxy-4-methyl-flavylium chloride (HMF). In aqueous solution, the ESPT mechanism involves solely the excited acid AH* and base A* forms of HMF as indicated by the fluorescence spectra and double-exponential fluorescence decays (two species, two decay times). However, upon addition of either 1,4-dioxane or 1,2-propylene glycol, the decays become triple-exponential with a term consistent with the presence of the geminate base proton pair A*center dot center dot center dot H(+). The geminate pair becomes detectable because of the increase in the recombination rate constant, k(rec), of (A*center dot center dot center dot H(+)) with increasing the mole fraction of added organic cosolvent. Because the two-step ESPT mechanism splits the intrinsic prototropic reaction rates (deprotonation of AH(+)*, k(d), and recombination, k(rec) of A*center dot center dot center dot H(+)) from the diffusion controlled rates (dissociation, k(diss) and formation, k(diff)[H(+)], of A*center dot center dot center dot H+), the experimental detection of the geminate pair provides a wealth of information on the proton-transfer reaction (k(d) and k(rec)) as well as on proton diffusion/migration (k(diss) and k(diff)).

Aumento da jornada de trabalho :qual a repercussão na vida dos trabalhadores da enfermagem?

The worker of the public service is loosing your acquisitive power by means of the politics of fiscal settlement. The ways out that were found in the health sector, especially in nursing, is being the increasing workday for beyond 40 or 20 hours established in the link of the work with the state. This survey has the object to identify the possible repercussion of the increasing workday in daily life workers from nursing in the public service of Rio Grande do Norte. The theory reference used was the work of Marx (1982) and Antunes (2000,2001) and the daily living in Heller (1991,1992). The methodology used was a qualitative survey in the exploration kind. The informations were gathered through interviews with open questions almost structured with workers of nursing, managers and representatives of entity. The analysis of informations were made through general categories, work, and daily life, using elements from dialetics-hermeneutics according to Minayo (1992,2002). In the analysis, it was identified that the ways that were found for the overcoming of the loss of acquisitive power were the many-employment; the extra scale of shift; the subletting of work posts and the substitution of friends in scales of work, and all of them being changed in increase. Other aspect realized was the move of rights, like vacation and medical license for the workers that act in extra scale. The tiredness, stress, and bad humor are influents factors in the development of work.. The reduction of free time makes in the workers ahguish because of the familiarity decreasement just as time to dedicate themselves to the technical-scientific improvement and for the cultivation of other aspects of subjectivity, as leisure, care and culture. The low salary and the non reajustment are the reasons for the adoption of part workers for the increasing workday, and government has been responsible for this situation. The conclusion was that the increasing workday has strong repercussions in the professional and personal daily life workers that made part of the survey

Um estudo sobre a utilização de sistemas, programas e ferramentas da qualidade em empresas do interior de São Paulo

O desenvolvimento e implantação de sistemas de gestão da qualidade e o uso de programas e ferramentas da qualidade são algumas das opções mais utilizadas pelos gestores para aumentar a competitividade de suas empresas. Nesse contexto, o objetivo deste artigo é apresentar o resultado de uma pesquisa tipo survey em que se verificaram e analisaram as principais características do processo de certificação ISO 9001, seus benefícios, suas dificuldades e quais programas e ferramentas da qualidade são utilizados em 236 empresas do interior do Estado de São Paulo. A pesquisa revelou que a certificação ISO 9001 gera benefícios significativos às organizações, tais como: melhoria dos processos internos e nos seus produtos; aumento da satisfação dos clientes; diminuição do número de não conformidades e de devoluções; aumento da produtividade e do lucro; melhoria no gerenciamento dos recursos e valorização da imagem da empresa no mercado. Ela também ratificou a importância da utilização dos programas e ferramentas da qualidade como forma de as empresas se adequarem melhor aos requisitos da norma ISO 9001. As dificuldades de desenvolvimento e implantação desses sistemas não se confirmaram para a amostra pesquisada. Apenas a resistência à mudança, dentre todas apresentadas, mereceu destaque para os pesquisados.

As vazões de outorga das bacias hidrográficas dos rios Aguapeí e Peixe

This work presents procedures for getting data to estimate grant flow by means of statistical and hydrological methods, acquired during the graduate course, of some streams in the watersheds of Aguapeí and Peixe rivers, in order to make available this data set to Sao Paulo State water and electrical energy department – DAEE and to the Committees of Aguapeí and Peixe watersheds. This study was performed using discharge data and the were a selection process to identify some faults in the historical series. Finally it was calculated the 7-day moving averages, Q7 and some characteristics discharges like Q90 and Q95. Taking into account the average discharge en seven days in a 10-year recurrence interval, it was estimated the grant flow of some streams. Data were generated for six posts inside the Aguapei and Peixe watersheds

Comunicação pública e acesso à informação: análise da atuação da SABESP em plataformas virtuais

This undergraduate research final paper analyzed the communication process carried out by the São Paulo State Water and Sanitation Company - Sabesp from the perspective of public communication, social capital and right to information theories. By monitoring Sabesp's institutional fanpage and website from 24 to 30 August 2015, it sought to assess the performance of Sabesp in disclosing public information on the context of the water supply crisis in São Paulo, concerning the fulfillment of requirements of the Right to Information Law (12.527/2011) and the need for interaction and dialogue between the institution and its stakeholders, taken as principles of public communication. The results suggest that digital media can enhance information flow and contribute to foster public relations and civic participation, but there are opportunities for Sabesp to improve communication and reach greater transparency

The role of youth sports in public health

Study 1: Schools provide a range of opportunities for youth to be active, however, over the past decade, these opportunities have been declining. Sports teams are a promising venue to promote physical activity yet limited research has examined the gender an ethnic differences in sport participation. The purpose of this study is to examine trends in sport participation from 1991-2009 among US high school students. Secondly, we examined the association between gender and ethnicity with sports over time. This serial cross-sectional study used surveillance data from the Youth Risk Behavior Survey, a probability based sample weighted to represent gender and race/ethnic subpopulations of US high school students. The findings of this paper reveal persistent gender and ethnic disparities for sports participation among US youth. Since sports teams may provide a substantial source of physical activity, greater efforts should be undertaken to increase the participation of girls, especially minorities, in sports teams. ^ Study 2: Sports team participation is congruent with teaching and supporting healthy eating, yet limited research has examined the association between sports participation and dietary behaviors. This study aims to determine the association between youth sports participation and dietary behaviors among elementary-aged children. Significant dose-response associations were observed between number of sports teams and consumption of most fruits and vegetables. The likelihood of eating fruit for boys increased with the number of sports teams (1 team: OR=1.89; 3 teams: OR=3.44, p<0.001) and the likelihood of consuming green vegetables for girls was higher with the number of sports teams (1 team: OR=1.50; 3 teams: OR=2.39; p<0.001). For boys, the odds of consuming fruit-flavored drinks was higher ( p=0.019) and the odds of drinking soda was lower (p=0.018) with participation in increasing number of sports teams whereas for girls, sports participation was positively associated with diet soda consumption (p=0.006). ^ Study 3: Parents and peers have been shown to have a strong influence over the physical activity, dietary, and sedentary behaviors of youth. Youth sports teams have the potential to offer physical activity, displace sedentary behaviors, and promote a healthy diet. The purpose of this study is to assess how peer and parental support for physical activity and healthy eating, coupled with sport participation, is associated obesity related risk factors including diet and sedentary behaviors. A secondary analysis of data from the School Physical Activity and Nutrition study, a state-representative survey, was conducted. Eighth (n=3,931) and 11th (n=2,785) grade students were categorized into four groups based upon the level of peer and parental support derived from a three item scale and their participation in sports (sports/high support, sports/low support, no sports/high support, no sports/low support). Linear models were conducted to determine the difference in means between these groups for the following outcome variables: previous day fruit and vegetable intake, scores for an unhealthy and healthy food index, and hours spent watching television, playing video games, and working on a computer. Eighth graders had significantly greater levels of parental support for healthy eating and physical activity compared to 11th grade. Both 8 th and 11th graders in the sport/high support for healthy eating from peers and parents scored significantly higher on the healthy food index than other groups. Eighth and 11th graders in the sport/high support for physical activity from peers participated in fewer hours of sedentary behaviors than any other group (p ≤ 0.032). Although it is thought that sport participation may offer opportunities to support a healthy diet and displace sedentary time by offering providing physical activity, our study found that parental and peer support for activity and healthy eating may further attenuate this association. Parents and peer support should be an important target when developing strategies to improve healthy diets and reduce sedentary time among youth, especially in the context of youth sports.
