title: Assessing the physiological quality of common bean seeds using the Vigor-S® system and its relation to the accelerated aging test

description: Abstract: Automated analysis of seed vigor stands out by allowing greater accuracy, standardization, objectivity, and speed in evaluation of the physiological potential of seed lots. The objective of this study was to evaluate the efficiency of the Vigor-S® system in assessing the physiological quality of common bean seeds compared to the information provided by the traditional vigor tests recommended for this species. Four genotypes of common bean were used, each one represented by four seed lots. Characterization of the physiological potential of the lots was carried out by the following tests: germination, first count of germination, seedling emergence, accelerated aging, and electrical conductivity. The results of these tests were compared with the data obtained from the image analysis technique, specifically the Vigor-S® system, which was used to evaluate seedling growth at two, three, and four days after the beginning of the germination test. Shoot length, primary root length, and seedling length were measured, as well as the growth index, uniformity index, and vigor index were calculated. Computerized analysis of seedling images using the Vigor-S® software is a reliable alternative for evaluation the physiological potential of bean seeds, and it produces information similar to evaluations traditionally used for that purpose.

title: Grounded Theory: methodology applied in education research

description: Abstract: It is identified that the grounded theory is little used in research in the area of Education. It presents different modes of interpretation according to whether it is Straussian or constructivist. It is questioned: how to characterize the GT steps and the possible applications in education research. It was delimited to describe the steps for the collection and analysis of the data in the research carried out with the grounded theory. Theoretical exploratory basis was used because it allows a deepening in the object of study and the establishment of bases for future researches. The experience with this methodology allowed to make the communication in a reflected way that could be of great value to the researchers in the area of education.

title: Modified NRCS-CN-TUH methods for distributed rainfall-runoff modeling

description: ABSTRACT Due to the relative ease of application, the CN and the Triangular Unit Hydrograph (TUH) methods are commonly used in hydraulic facilities design. This work adapts these methods to incorporate the spatial variability of the physical characteristics of the catchment. The flow travel time (tv) is computed from the DEM and the CN and TUH methods are adapted to produce results on a pixel basis. This methodology is applied to the Cascata I catchment (Porto Alegre - RS), considering two variants: i) TUHout - tv calculated from each pixel up to the catchment outlet; ii) TUHdown - tv computed from one pixel to the immediate downstream. The proposed methodology showed potential to be used for hydrologic modeling of rainfall events in small catchments, as an alternative for providing information useful for urban drainage management, as the characterization of catchment areas with distinct behavior regarding velocities and potential for runoff generation. On the other side, the results showed an underestimation of peak discharges and time to peak. Initial abstraction losses of the CN method lower than the one originally prescribed provided more realistic results, in agreement to recent studies. There is the need for an improvement of the methodology for the characteristics of the Brazilian catchments besides the simple adaptation of the classical equations of the CN method to its distributed form.

title: Spatial discretization influence on flood modeling using unit hydrograph theory

description: ABSTRACT The Unit Hydrograph (UH) is the most popular method for flood related applications. There are several conceptual and geomorphological models based on UH and coupled with different spatial discretizations. However, there are few studies concerning the evaluation of UH models according to semi-distributed approaches. This study aimed to assess the influence of lumped and semi-distributed modeling on the applicability of Soil Conservation Service UH (SCS UH) and Clark’s Instantaneous UH (Clark’s IUH) for estimation of flood hydrographs. The methodological procedures were conducted in the Hydrological Modeling System (HEC-HMS) using rainfall-runoff events of a gauged watershed in Southern Brazil. The main conclusions were: a) CIUH under the semi-distributed approach provided slightly superior performance; b) CIUH was able to effectively estimate the direct surface runoff hydrographs even for long duration rainfall events; c) SCS UH presented more accurate hydrographs for lumped modeling; d) the Nelder and Mead algorithm may have limited application.

title: A population-based study of cognitive impairment in socially vulnerable adults in Argentina. The Matanza Riachuelo Study. Preliminary Results

description: Population aging has taken place intensively worldwide, even in developing countries. These countries have population groups with low resources and basic unmet needs that are frequently omitted from epidemiological studies. OBJECTIVE: The purpose of this study was to determine the prevalence of cognitive impairment (CI) and dementia in an economic and socially vulnerable population from Argentina. METHODS: A door-to-door observational population-based survey among adults over 60 years of cognitive impairment and dementia in the social vulnerable area of the Matanza Riachuelo Basin, in the suburban area of Buenos Aires, Argentina was conducted. Trained psychologists interviewed subjects and a proxy informant. A standardized protocol including a socio-demographic questionnaire, the Mini-Mental State Examination, the Geriatric Depression Scale and a functional inventory for IADL and ADL was administered. Diagnoses were divided into three general categories: normal cognitive function, cognitive impairment-no dementia (CIND) and dementia. RESULTS AND CONCLUSIONS: A total of 2437 elderly persons were assessed, of which 73.6% fulfilled inclusion criteria. The prevalence of CI among those over 60 was 26.4% (18.1% CIND and 8.3% dementia) with higher prevalence of dementia in younger individuals than rates reported in developed counties, probably due to low control of vascular risk factors. This information can help inform health public decisions in the generation of programs and plans for the prevention, diagnosis and treatment of cognitive impairment in this type of socially vulnerable population.

title: Automatic calibration of a large-scale sediment model using suspended sediment concentration, water quality, and remote sensing data

description: ABSTRACT Calibration and validation are two important steps in the application of sediment models requiring observed data. This study aims to investigate the potential use of suspended sediment concentration (SSC), water quality and remote sensing data to calibrate and validate a large-scale sediment model. Observed data from across 108 stations located in the Doce River basin was used for the period between 1997-2010. Ten calibration and validation experiments using the MOCOM-UA optimization algorithm coupled with the MGB-SED model were carried out, which, over the same period of time, resulted in 37 calibration and 111 validation tests. The experiments were performed by modifying metrics, spatial discretization, observed data and parameters of the MOCOM-UA algorithm. Results generally demonstrated that the values of correlation presented slight variations and were superior in the calibration step. Additionally, increasing spatial discretization or establishing a background concentration for the model allowed for improved results. In a station with high quantity of SSC data, calibration improved the ENS coefficient from -0.44 to 0.44. The experiments showed that the spectral surface reflectance, total suspended solids and turbidity data have the potential to enhance the performance of sediment models.

title: São Paulo Curricular Mathematics Material: using option by teachers of a São Paulo municipality

description: Abstract This paper analyzes the material concerning the Mathematics Curriculum of the State of Sao Paulo, in force since 2008, and the perceptions of teachers regarding its use. It is a qualitative, analytical-descriptive research, grounded on the material analysis and in a questionnaire applied to 80 Mathematics teachers from the public school network of Presidente Prudente municipality (SP). The material does not indicate significant changes in the contents in relation to previous curricula, but it establishes learning situations as teaching organizers. Results highlight that most teachers would not use the material in a spontaneous way. The rationale presented by the teachers refer mainly to the lack of theory in the material and to the students’ lag of knowledge.

title: The Diffusion Network of the School without Party project on Facebook and Instagram: conservatism and reactionarism in the Brazilian conjuncture

description: Abstract: This article discusses how conservative thought has been widespread through social networks from supporters of the Movement "Escola sem Partido" (ESP, School Without Party). We start with the analysis of the social medias Facebook and Instagram, seeking to verify who are the supporters of the ESP and the way in which their discourse is structured in social networks. The analysis carried out indicates who the proponents and supporters of ESP are, and states that this proposal is not non-partisan because it has strong links with reactionary groups who seeks to gain power. In addition to that, we find that ESP supporters act militantly in social media, openly disseminating conservative values, especially against debates on gender issues.

title: Evaluation of vigor and tolerance of sweet corn seeds under hypoxia

description: Abstract: Evaluation of the physiological potential of seeds by fast and efficient methods is an important step in the process of production and commercialization of sweet corn seeds. The aim of this study was to discriminate sweet corn seed lots by applying multivariate methods regarding the usual vigor tests to verify the sensitivity of these seeds to flood conditions and to verify if the submersion test has potential for classifying lots of this species regarding vigor. Five seed lots of sweet corn were tested for moisture content and physiological potential. Cluster analysis and principal component analysis were performed on the data to discriminate the seed lots regarding initial vigor. Subsequently, two of these lots were selected for the water submersion test, performed with four replicates of 150 seeds, which were submerged in 100 mL of distilled water for 0, 24, 48, 72, and 96 hours at 25 ºC, and they then underwent the germination test. Discrimination of sweet corn seed lots is possible through multivariate analysis. Sweet corn seeds are sensitive to submersion in water; however, the test did not allow seed lots to be differentiated for vigor.

title: Neighbourhood unity: a case study of the transformations of a planning idea

description: Abstract This paper discusses the outcome of the neighborhood unit as a North-American planning idea applied to the layout of three Brazilian new towns: Goiânia – the new capital of Goiás state planned in 1933 and reshaped in 1937; Brasília, whose pilot plan was selected through a 1957 national design competition; and Rurópolis, one of the several new towns planned and built along the Transamazonian highway in early 1970s. In distinct contexts, Brazilian town planners recurrently adopted the configuration of small residential communities grouped around the elementary school settled amid open spaces, apart from vehicles and within abundant greenery, as a modern way to constitute urban cells and thus foster the community sense. However, by analyzing the configuration of the neighborhood unit in these three case studies and report their eventual construction, occupation and use, this paper unveils the transformations of the original idea as a result of the residents’ reactions, due to mismatching or rejection of a certain predetermined life style; thus the paper also points to issues as modern town planning utopia and ideal urban forms.
