Abstract: The world maritime transportation is suffering a large increase in recent years and as a result of this increased on global trade, there is a consequent increase in waterway transportation and demand for fossil fuels, resulting in emissions of air pollutants. Consequently, the impact of transport emissions on climate change was put on the list of priorities. It has a high fuel demand as a result of continuous use of main engines for propulsion, electricity and heat production. The highest exposure levels of air pollution are found in ports and near them because most of the world fleet is positioned in these areas. The port of Rio de Janeiro city, in the Southeast Brazilian coastal, is inserted in the Guanabara Bay (GB), where the breezes recirculate pollutants in Metropolitan Region of Rio de Janeiro (MRRJ). Therefore, the aim of this research was to use the Brazilian Regional Atmospheric Modeling System (BRAMS) to generate the wind fields in the MRRJ and to calculate the trajectories of pollutants emitted on GB related to the waterway transportation, using a 3D kinematic trajectories model. Results demonstrated that for the periods analysed, the Central and west areas in the coastal region of the Rio de Janeiro city were the local most affected in the summer. In winter the trajectories reached the cities of the Rio de Janeiro and Duque de Caxias. Both in summer and winter, the trajectories followed towards the South Atlantic Ocean in the morning. Conclusions about this study show the need of decision-making process for better management of waterway transportation sector, improving the harmful effects on air quality in cities located in coastal regions.

Abstract: this paper analyzes supplemental education in brazil, taking into account two basic aspects: level of coverage and personal economic results. the program has a low degree of coverage, even among those who could benefit from the program. the estimates of economic results have shown that 2nd level supplemental program produced lower gains than the regular program, but the 1st level supplemental program, when compared to the 1st level regular system, demonstrated the same absolute gains and an income growth rate twice higher for each additional year of study. this paper highlights the need for better understanding of why the 1st level supplemental education program has a low degree of coverage in the presence of such a high economic return.
Multivariate Analysis of Extreme Physical, Biological and Chemical Patterns in the Dynamics of Aquatic Ecosystem  [PDF]
Marilia Mitidieri Fernandes de Oliveira, Gilberto Carvalho Pereira, Nelson Francisco Favilla Ebecken, Jorge Luiz Fernandes de Oliveira
Journal of Environmental Protection (JEP) , 2015, DOI: 10.4236/jep.2015.68080
Abstract: This study is a part of the research in monitoring systems of environmental impacts in coastal re-gions in order to develop trophic dynamic models to be used in the aquatic systems management. Meteorological influences in the variability of the nutrients, larvae concentration, dissolved oxygen (DO) and chlorophyll a were investigated in a region where upwelling occurs. Extreme seasonal variations of reanalysis, QuikSCAT, and surface stations from the southeast coast of Brazil, as well as, surface seawater data collected in Anjos Bay, Arraial do Cabo city northeast of Rio de Janeiro state, are analyzed. Seasonality and correlations are applied to verify the relationship between them, considering minimum values of sea surface temperature (SST) and sea level variation and maximum values of the other variables. Principal Component Analysis (PCA) and Hierarquical Cluster Analysis (HCA) are applied to verify spatial and temporal variances and to describe more clearly the structure of the local ecosystem. The seasonality of northeasterly extreme wind stress follows the seasonal pattern expected for the study area with peaks during spring. The SST has a well-defined seasonal pattern with maximum peaks from February to July and minimum peaks from September to January. Chlorophyll a presents higher seasonal peak in February, being in accordance with DO; both are related to the maximum primary productivity. Correlations of the physical variables (local and remote) with nutrients and larvae present a relatively similar pattern around 0.5, showing these variables have a reasonable interaction with the meteorological forcing. PCA shows a strong variability in pressure data around 0.9, which may be related to the seasonal variations in South Atlantic subtropical anticyclone (SASA) and consequently to the occurrence of upwelling in the region. HCA shows the twenty-five parameters into two big clusters with predominance of biotic variables in one side and abiotic ones at the other. The degree of refinement of similarities allowed a division into six clusters of samples, giving the most satisfactory results at forming distinct clusters with more accurate regarding physical and biological elements.

Cadernos de Saúde Pública , 2004, DOI: 10.1590/S0102-311X2004000100034
Abstract: this survey is part of a more comprehensive study on the health consequences of pesticide exposure. in the county (municipality) of paty do alferes, rio de janeiro state, brazil, 55 agricultural workers were interviewed on the use of pesticides, use of personal protective equipment, data on health status, and symptoms related to pesticide exposure, disposal of agrochemical containers, and technical assistance. the most widely used pesticides were insecticides such as abamectin, organophosphate compounds, and pyrethroids, and fungicides such as mancozeb, chlorothalonil, and copper products. as a rule, pesticides are handled carelessly, and 92% of workers involved in the mixing, loading, and spraying of insecticides and fungicides used no protective clothing or equipment whatsoever. some 62% of workers reported at least one illness associated with mixing or spraying pesticides. the most frequently reported symptoms were headache, nausea, vomiting, dizziness, skin irritation, and blurred vision, and 21% of affected workers required medical care. in more than half (51%) of the cases, workers reported using organophosphate insecticides from toxicological class i when they felt sick.

Abstract: the aim of this work was to evaluate the effect of slag and limestone, on the available p concentration of the soil planted with sugarcane. a field experiment was conducted in ituverava, sp, brazil, in a red-yellow oxisol. calcitic limestone and the slag were added in order to increase the base saturation to 50%, 75% and 100%, in addition to the control without correction. the linear effect of the slag on the soil available p, contrasting the lack of relationship when the limestone was applied, suggests that the positive effect of the slag is mainly due to the silicate effect than to the ph effect.

Alves, Francisco Selmo Fernandes;Olander, Harvey John;
Pesquisa Agropecuária Brasileira , 1999, DOI: 10.1590/S0100-204X1999000700025
Abstract: ten goats were vaccinated with a 3% toxoid, ten vaccinated with a bacterin and two control groups (five animals each) inoculated with brain heart infusion and saline solution, respectively. all animals were skin tested with a crude antigen of formalin-killed corynebacterium pseudotuberculosis bacterial cells. all goats were challenged with a virulent c. pseudotuberculosis thirty days after vaccination. neither the vaccinated nor control goats responded to the skin test prior to infection. after the challenge, dermal reactions were demonstrated in all animals at one week, five and ten weeks. the diameters increased from the first week, five and ten weeks. the reactions were more proeminent at ten weeks. the results of this study indicate that skin testing with a specific bacterial antigen of c. pseudotuberculosis may be useful in goats for field diagnosis of caseous lymphadenitis or as an experimental tool to monitor progress of the disease.

Abstract: the objective of this work is to identify the mechanisms of risk management currently adopted in investment activities of municipal retirement plans (rpps) of the state of rio grande do sul, brazil. the methodology applied in the research is descriptive (using survey techniques) and quantitative (using probabilistic research). the research was accomplished in the period of december 2007 to february 2008 in the 303 municipal districts of the state of rio grande do sul that maintain constituted rpps. the survey received 84 municipal districts responses, allowing the research to reach a 9% error level in the probabilistic approach. the results of the research demonstrate 58% of the managers of rpps declare not to possess a formalized investment policy; 70% declared not to maintain specific investment management sound practices and 74% informed they not to have investment management specific support systems. the cluster analysis provided the characterization of districts grouped by risk management practices combined with other socio-economic indicators. three distinct clusters were identified, showing, as expected, the best practices among the rpps are adopted by larger districts with larger investment volumes. finally, in spite of brazilian regulation recent advances, the results of the research demonstrate that mechanisms of risk control are not adopted in risk management of the investment activities of municipal retirement plans.
Avalia??o pós-operatória imediata da influência da desinser??o da valva tricúspide no tratamento da comunica??o interventricular
MOREIRA NETO, Francisco Fernandes;Sgarbieri, Ricardo Nilson;

Abstract: although the tricuspid valve and its attachments can sometimes obscure the margins of the ventricular septal defect from the vision of the surgeon, concern for valvular competence has made surgeons hesitate to take down the tricuspid valve. in this paper, the records of 34 patients divided into two groups (comparable by gender, age and associated anomalies) were reviewed retrospectively. treatment of the ventricular septal defect was done without (group i, with 19 patients) and with (group ii, with 15 patients) takedown of the tricuspid valve to determine the degree of the tricuspid regurgitation and also the incidence of residual ventricular septal defects and atrioventricular block. the anterior and septal leaflets of the valve were taken down at the annulus and resuspended after vsd repair with running 6-0 polypropylene sutures. the degree of valvular regurgitation and the presence of residual vsd were determined by echo done on post-operative day one and at the the patient's discharge. valvular regurgitation was graded as none in 12 patients of the group i and in 10 patients of the group ii; trivial regurgitation in 5 patients of group i and 4 of group ii; mild to moderate regurgitation in 2 cases of group i and 1 in group ii. no patient had severe regurgitation. even with a small number of cases, there was no statistically significant difference between the groups. there was only one case of residual vsd in group i with spontaneous closure. the mortality in group i was 10.5% and 6.6% in group ii. the authors conclude that takedown and re-suspension of the tricuspid valve in vsd repair surgery does not adversely affect valve competence neither increases the incidence of residual vsd or the incidence of a-v block.
Promotores de permea??o para a libera??o transdérmica de fármacos: uma nova aplica??o para as ciclodextrinas
Martins, Maria Rita Fernandes Morais;Veiga, Francisco;
Revista Brasileira de Ciências Farmacêuticas , 2002, DOI: 10.1590/S1516-93322002000100004
Abstract: the present work is a short revision about transdermal permeation enhancers, their mechanism of action including some examples. routes of permeation across the skin and transdermal delivery are also described. we focus cyclodextrins and their derivatives, structure, chemical properties, formation of inclusion complexes and their action as excipients in transdermal drug delivery systems. cyclodextrins are a very important group of excipients used in pharmaceutical technology. one of the most extraordinary properties of cyclodextrins is their ability to increase transdermal drug delivery without affecting the barrier function of the skin.
