title: Microcystin-LR removal from Microcystis aeruginosa using in natura sugarcane bagasse and activated carbono

description: Abstract Microcystin-LR is a type of toxin released by the Microcystis aeruginosa cyanobacteria found in water sources used for human consumption. It can cause illness and even death if not completely removed in conventional water treatment. The retention of this toxin is often accomplished by the adsorption process in activated carbon in water treatment plants. In this study, a comparison was made between the retention of microcystin-LR by activated carbon and by sugarcane bagasse in natura applied as a bio-adsorbent. Adsorption experiments were performed after the physical and chemical properties of the bio adsorbent and the activated carbon were characterized. The adsorption performance was evaluated by the toxin removal efficiency and the maximum adsorption capacity. Average removal efficiencies of the toxin resulted in 65.25; 41.74 and 11.75% for the activated carbon and 24.15; 18.92 and 12.27% for the sugarcane bagasse for concentrations of 2.36, 3.33 and 3.83 µg L-1, respectively. The bio adsorbent presented removal efficiency for the toxin similar to that observed in the activated carbon for the concentration of 3.83 µg L-1. Maximum adsorption capacity obtained with better linear adjustment to the Freundlich isotherm was 6,047.84 µg g-1 (toxin concentration of 3.83 µg L-1) for sugarcane bagasse and 338.61 µg g-1 (toxin concentration of 2.36 µg L-1) for activated carbon.

title: Listeria ssp. in beef carpaccio and resistance profile to antimicrobial agents

description: The present study was conducted to verify the occurrence of Listeria spp. in 50 samples of beef carpaccio sold in bars and restaurants; and to evaluate the resistance profile to antimicrobial agents used in the routine treatment of infections. It was found that 20% of samples from restaurants and 35% from bars were contaminated with Listeria spp. Among the species, L. welshimeri was most frequently isolated (81.82%), followed by L. grayi, (13.66%) and L. monocytogenes(4.55%). The Oxford agar plating medium was the most efficient. The resistant behavior occurred to all antimicrobial agents tested, except tetracycline, to which 95.5% of the strains were sensitive. Multidrug resistance was observed in 68.75% of the strains analyzed. Thus, it is concluded that the consumption of beef carpaccio represents a potential risk, and a serious public health problem, especially due to the confirmation of pathogenic strains that are resistant to major antimicrobial agents used in the treatment of listeriosis.

title: Occurrence of anti-Brucella abortus agglutinins in small ruminants in Sergipe

description: ABSTRACT: The objective this study was to evaluate the occurrence of small ruminants seropositive for Brucella abortus in Sergipe, Brazil. Samples of sheep (1,200) and goats (675) serum blood was collected from 101 farms of 25 counties of the three mesoregions of the state. The technique of Acidified Buffered Acid stained with Rose Bengal (RB) was used and all samples confirmed a positive result using the 2-Mercaptoethanol technique. Four (0.21%) seropositive animals were diagnosed by technique AAT stained with RB, three sheep’s (0.25%) and a goat (0.15%), were confirmed by the 2ME test. In all the positive properties, the intercropping of small ruminants with cattle was adopted, favoring the contact with the agent. The prevalence of anti-B. abortus antibodies in herds of small ruminants in Sergipe is described for the first time, and is low, however, it is important to identify seropositive animals to be discarded due to their zoonotic potential.

title: Analysis of notifications of acute intoxication, by agrochemicals, in 38 municipalities of the state of Paraná

description: ABSTRACT Paraná is the second largest consumer of agrochemicals in Brazil, and its notification of acute intoxications doesn't correspond to this reality. It was aimed to verify the correlation between the consumption of agrochemicals in the municipalities of Paraná and the notification of acute intoxications. Databases were analyzed on the consumption of agrochemicals and occurrence of intoxications. Interviews with epidemiological surveillance agents were conducted, to understand the process of identification and notification of cases. There was no evidence of correlation between consumption and notification of acute intoxication. It was concluded that there is underreporting of agrochemicals intoxications in Paraná, due to structural fragilities in health services.

title: Knowledge and Use of the Flora in a Quilombola Community of Northeastern Brazil

description: ABSTRACT An ethnobotanical survey was carried out in the Quilombola Community of Serra do Evaristo in the municipality of Baturité, Ceará state, Brazil. We interviewed 41 residents who provided information on the plants used, the types of use, the preparation methods, the purchase location of the plants and their knowledge source. One hundred and fourteen species belonging to 53 botanical families were recorded. Six types of use were reported, with most species being used for medicinal purposes (43% of the species), followed by food (25%), decoration (23%), construction (5%), domestic fuel (3%) and ritualistic purposes (3%). The most cited species were Musa paradisiaca L. (banana), Zea mays L. (corn), Phaseolus vulgaris L. (bean), Citrus sinensis (L.) Osbeck (orange), Melissa officinalis L. (common balm), Aloe vera (L.) Burm.f. (aloe vera), Cymbopogon citratus Stapf. (lemon grass), Mentha sp.(mint) and Psidium guajava L. (guava). The knowledge and use of the plants is part of a cultural heritage passed down through families, and has been helping the survival and maintenance of the Quilombola identity in the studied community.

title: ACCESSIBILITY INDEX ELABORATION BY NETWORK GEOSPATIAL ANALYSIS

description: ABSTRACT The objective of this study is, by means of geoprocessing techniques, to prepare an accessibility index and use it to evaluate the suitability of the public transport network offered to the various regions and social classes present in the metropolitan area of Rio de Janeiro (RMRJ). This study starts from the premise that there is a socio-spatial segregation, which is unlikely to change. Thus, the proposed accessibility index aims to assess the quality of the public transport structure offered regarding its connectivity to different locations and jobs as well as the ease (or difficulty) of access to different public transport modes. The results indicate that the public transport system i is ineffective as an instrument for overcoming socio-spatial segregation, as there is a tendency for individuals with lower incomes to occupy areas with the lowest level on the proposed accessibility index. This tendency can be explained by the higher quality of public transport in the central regions and the increased value of areas with a better supply of transport, even in peripheral areas.

title: The Influence of Corporate Governance on the Mitigation of Fraudulent Financial Reporting

description: Abstract Purpose: This study analyzes the influence of the corporate governance structure in terms of mitigating the likelihood of fraudulent financial reporting (FFR) by firms in Brazil. Design/methodology/approach: For this, we analyze the data of 314 publicly traded companies to estimate the likelihood of bankruptcy and the possibility of earnings manipulation, for subsequent identification of . Findings: Our results show that in 5.5% of cases there is an indication that FFR is likely, bankruptcy is predicted in 16.9% of cases, and the likelihood of earnings manipulation is identified in 17.7%. The corporate governance structure of the firms influences FFR mitigation, either directly or indirectly by reducing the chances of bankruptcy or earnings manipulation. We note that board-related governance practices are more effective against predicted bankruptcy, and audit-related practices are more related to reducing earnings manipulation. Originality/value: The main contributions of this study lie in it identifying the probabilities of reporting fraud, bankruptcy, and earnings manipulation for companies in Brazil, as well as it verifying that corporate governance has been effective in mitigating these problems, either directly or indirectly. Thus, this information is useful for investors and regulators in this market.

title: Conditional Cash Transfer Programs: Brazil and Mexico in a comparative perspective

description: ABSTRACT In the 1980s, Latin America experienced economic crises, with structural adjustment programs and rising unemployment, which accentuated poverty and social inequalities. Subsequently, several countries adopted Conditional Cash Transfer Programs, in a scenario of emphasis on social policies in the fight against poverty. In Mexico and in Brazil, programs were preceded by other income transfer initiatives for the poor, initiated respectively in the 1980s and 1990s. The objective of the study was to analyze the programs Bolsa Família in Brazil (created in 2004) and Oportunidades in Mexico (created in 2002). The analysis reference was based on the historical-comparative perspective and literature review, documental analysis, analysis of secondary data analysis and semi-structured interviews were used as research techniques. Differences were observed between the programs in terms of objectives, design and conditionalities, including health. Despite some positive effects on income, health and education indicators, such programs are limited for the fight against poverty.

title: Geological modeling of a stratified deposit with CAD-Based solid model automation

description: Abstract The planning stages of mining activities require many comprehensive and detailed analyses. Determining the correct orebody model is the first stage and one of the most important. Three-dimensional solid modeling is one of the significant methods that can examine the position and shape of the ore deposit. Although there are many different types of mining software for determining a solid model, many users try to build geological models in the computer without knowing how these software packages work. As researchers on the subject, we wanted to answer the question "How would we do it". For this purpose, a system was developed for generating solid models using data obtained from boreholes. Obtaining this model in an AutoCAD environment will be important for geologists and engineers. Developed programs were first tested with virtual borehole data belonging to a virtual deposit. Then the real borehole data of a cement raw material site were successfully applied. This article allows readers not only to see a clear example of the programming approach to layered deposits but also to produce more complicated software in this context. Our study serves as a window to understanding the geological modeling process.

title: Is there any association between vitamin D levels and polycystic ovary syndrome (PCOS) phenotypes?

description: ABSTRACT Objective The aim of this study was to assess the serum vitamin D level in a retrospective study in women with polycystic ovary syndrome (PCOS), according to the different phenotypes of the disease. Subjects and methods In this retrospective study, the records of 351 infertile women who were diagnosed with PCOS were examined, and 200 of them were enrolled in the study randomly in 4 PCOS phenotypes. Fifty normal ovulatory women with the history of male factor were selected as the control group. Parameters, including age, infertility duration, body mass index (BMI), hormone profile, as well as the serum vitamin D level were compared among the 4 phenotypes, with the P-value ≤ 0.05 considered statistically significant. Results The findings showed a higher serum vitamin D level in the control group than in PCOS patients, which was statistically significant (P &lt; 0.001). In addition, there was no significant difference in the serum vitamin D level among the four phenotypes of PCOS. Conclusions No significant difference was found in the serum vitamin D level of the different phenotypes of PCOS. Further studies with larger sample sizes are recommended to be done to establish the role of the serum vitamin D level in PCOS patients.
