title: Multivariate index of soybean seed vigor: a new biometric approach applied to the effects of genotypes and environments

description: Abstract : The objective of this work was to apply a multivariate index of vigor in soybean seeds to identify the differential effects of the genotypes x environments interaction on the quality of the seeds produced in the 2016/2017 harvest season. The experiment was conducted in a randomized block design, organized in the factorial scheme, with five seed production environments x 20 soybean genotypes, arranged in four replications. The seed production environments of Tenente Portela - RS and Santa Rosa - RS soybeans are characterized as the environments that express the highest magnitude for seed vigor index, however biometrically Sarandi - RS has been defined as the optimal environment for the production of high vigor seeds according to the tested genotypes. High seed vigor index were expressed for the genotypes TMG 7161 RR, AMS Tibagi RR, BMX Magna RR, Fepagro 37 RR and NA 5909 RG. The differential effects of the genotypes x production environments interaction of soybean seeds influenced by more than 68% the vigor index of the seeds produced.

title: Interpretive route of the historic center of Cáceres/MT, for tourism and heritage education purposes

description: Abstract The objective of this study is to develop an interpretative route to the historic center of Cáceres/MT, which can be both a tourism product and an educational resource for activities related to heritage education. The tools used to collect data were document and field research, photography record and collection of geographic coordinates through DGPS. Th data collected in the field were spatialized, and associated with textual information, enabling the creation of products: satellite-map image, themed-map and pocket guide. Three experimental visits, with visitors (tourism event) and students, were carried out in order to validate the route; and at the end of the visit the participants rated the route in terms of itinerary, relevance of historical and cultural information of the twelve stopovers along the way. The comments and suggestions made by the participants were taken into account in the final proposal. The assessment made by the target segments led us to conclude that the product proposed contributes to the development of tourism and heritage education. The key role of Cáceres in the demarcation and protection of border between Portuguese and Spanish colonies, in 1778, is highlighted. The product put forward is part of a wider research project called"Tourism and geographic information system of Cáceres, MT: contributions on planning and local development", funded by the Fundação de Amparo à Pesquisa do Estado de Mato Grosso - FAPEMAT

title: Attitudes towards physician-assisted suicide and euthanasia in Spanish university students

description: Abstract Attitudes toward physician-assisted death among medical students differ between populations. The aim of this study was to explore attitudes towards euthanasia and physician-assisted suicide among Spanish university students. A cross-sectional survey was conducted by asking undergraduate students (Medicine, Nursing and Law) of the University of Santiago de Compostela to complete an anonymous 17-item questionnaire. Most participants exhibited a positive attitude towards physician-assisted suicide (54%) and euthanasia (75%), as well as towards their legalization. Attitudes were consistent with the underlying ethical reasoning, with no differences in terms of age, gender or academic degree. In addition, consistency was found between attitudes and willingness to participate in physician-assisted suicide and euthanasia, should they be legal. The results showed that the attitudes of medical students towards euthanasia and physician-assisted suicide were positive and similar to non-medical students.

title: The Cogollo Group and the oceanic anoxic events 1a and 1b, Maracaibo basin, Venezuela

description: ABSTRACTCarbonates of Cogollo Group (Apón, Lisure and Maraca formations) constitute the broader calcareous platform system originated during Aptian and Albian of Cretaceous in north-western South America, Maracaibo Basin, Venezuela. On the shallow shelf, a variety of calcareous sedimentary facies were deposited during marine transgressive and regressive cycles. Some of them developed porosity and constitute important hydrocarbon reservoirs. Due to some major marine transgressions, from early Aptian, the anoxic environment and characteristic facies of a pelagic environment moved from the outer slope and basin to the shallow shelf, during specific time intervals, favouring the sedimentation of organic matter-rich facies, which correspond to the oceanic anoxic events (OAEs) 1a and 1b. The source rock of Machiques Member (Apón Formation) was deposited during early Aptian OAE 1a (~ 120 Ma). The source rock of Piché Member, located at the top of the Apón Formation, was deposited during late Aptian OAE 1b (~ 113 Ma). Finally, La Luna Formation, from Cenomanian, that covers the OAE 2 (~ 93 Ma), represents the most important source rock in the Maracaibo Basin. In this way and based on sedimentological and organic geochemistry results from the determinations performed on 247 samples belonging to six cores in the Maracaibo Basin, we propose these two organic-rich levels, deposited on the shallow shelf of the Cogollo Group, as "effective source rocks", additional to La Luna Formation, with oil migration in relatively small distances to the porosity facies.

title: Visibility of scientific journals: A study based on the Website of Scientific Journals at Universidade Federal do Rio Grande do Sul

description: The study addresses the visibility of electronic scientific journals, as well as the characteristics that promote, especially focusing on those hosted on the Portal of Scientific Journals of the Universidade Federal do Rio Grande do Sul. The study assesses the degree of visibility of these journals on the Internetby means of their presence in information sources. The theoretical reference addresses the following themes: scientific communication; scientific journals; visibility and searchability; information sources on portal; bibliographic databases and open access. This is a descriptive and exploratory study that combines qualitative and quantitative data. The corpus of research was composed of 34 titles. Essential information about the journals was collected, giving emphasis to the characteristics that promote their visibility. It was found that Human Sciences is the area with the greatest number of journals at the University, 29.4% of all publications. Open access is adopted by all journals in the sample. Once the information sources had been mapped, it was found that the majority of journals appear in the information source Latin American Periodicals Tables of Contents, followed by Latindex.Despite thelimitedpresence of the journals in international information sources, it was concluded that the journals hosted on the Website of Scientific Journals seek to adapt to characteristics that promote their visibility. The study suggests a number of new studies, deepens the analyses, and addresses other themes related to visibility and, especially, bibliometric studies.

title: Antibiotic resistance in surface waters from a coastal lagoon of Southern Brazil under the impact of anthropogenic activities

description: Abstract Wastes arising from human activities can reach water bodies and contribute significantly to the presence of antibiotic resistant bacterial populations in aquatic environments. The objective of this study was to evaluate the cultivable antibiotic resistant bacterial populations from a coastal lagoon impacted by agriculture and urbanization activities. Water samples were collected in low and peak season and characterized regarding physicochemical variables, microbiological indicators and the presence of antimicrobial residues. In order to analyze the presence of resistant bacterial populations, the samples were grown in the presence of nalidixic acid, ceftazidime, imipenem and tetracycline. Genes associated with β-lactamic resistance (bla CTX-M-like, bla GES-like, bla OXA-51, bla OXA-23-like, bla SHV-like, bla TEM-like and bla SPM-1), class I integron and efflux systems (tetA, tetB, acrA, acrB, tolC, adeA, adeB, adeR, adeS, mexB, mexD, mexF and mexY) were analyzed by conventional in vitro amplification. Although antimicrobials residues were below the detection limit, resistant bacteria and resistance determinants - bla GES, class I integron, adeS, acrA, acrB, tolC, mexB, mexF - were present at almost all points, in both seasons and for all antimicrobials assessed. The high numbers of resistant bacteria counts observed after the antibiotic treatment were positively correlated to the urbanization effects on the Lagoon. Some resistant populations were even higher in the low season samples, indicating the importance of a systematic evaluation of antibiotic resistance on water resources.

title: Development of a low cost force platform for biomechanical parameters analysis

description: AbstractIntroduction: The maintenance of balance and body orientation during standing is essential to perform different activities. One of the devices used to measure balance them is the force platform. This device measures the ground reaction force (GRF) and displacement of the center of pressure (COP), both biomechanical parameters involved in human motion. This article proposes a new design for non-commercial low-cost force platforms for scientific research purposes. Methods for calibration and validation are also described. Methods A force platform, developed according to International Standards of Measurement and dedicated to measuring feet contact forces was built for approximately one tenth of the cost of commercial platforms. Calibration was performed by loading known masses, centralized or distributed, on the platform. An experimental study was conducted with four volunteers in different conditions to validate and verify the practical applicability of the device. Results The platform calibration showed an adequate connectivity, linearity and reliable measurement of the variables proposed in this research, being suitable for studies of human postural behavior. Conclusion Based on the validation results, we believe the low-cost platform can be used as stabilometric device to measure postural control and balance in clinical or sports experiments. However future studies will be required to provide a final validation and compare its performance with other force platforms.
