title: Urban Occupation and its Hydrologic Impacts in the Upper Mineirinho Watershed

description: This work aimed to establish and compare different scenarios of urban occupation and analyze their hydrologic effects. It evaluates downstream flood risks caused by upstream urban growth surrounding the implantation of the new Campus of the University of Sao Paulo - USP in the municipality of Sao Carlos, Sao Paulo state, Brazil. Four scenarios of urban occupation have been depicted: preurbanization (1972); scenario 2000; prospective scenario with Master Plan (until 2025, “CPD”); and expected situation without Master Plan (until 2025, “SPD”). The comparison of the different scenarios was outlined using the hydrologic model IPH II. Hydrologic modeling simulations showed that maximum stream flow discharges of scenario 2025 “SPD” would present an increase of 388.0% compared with the preurbanization scenario of 1972 and of 319.4% compared with the scenario 2000. Maximum stream discharges and peak timing of the scenario with Master Plan of 2025 (CPD) would present, respectively, a reduction of 22.3% and an increase of 50 minutes compared with the scenario without Master Plan of 2025 (SPD).

title: GerminaQuant: a new tool for germination measurements

description: Abstract:The seed technologies related with germination and seed research has provided unprecedented opportunities for the biologic research community. Researchers require such information to rapidly determine the speed of seedling emergence. However, an immense amount of data must be analyzed to achieve this goal. In this paper, we introduce a computer software designed for broad use to facilitate the understanding of germination processes and their analysis. GerminaQuant 1.0 was written in the C++ programming language and presents a user-friendly interface. The accuracy of the software was tested using fifty different matrices, whose output values were compared with other spreadsheets available on the web. With data analysis, we showed that the GerminaQuant is capable of generating mathematical calculations with extreme accuracy, besides have a good performance and wide ease of use in any kind of computer. In addition, the new software has been tested by at least eighty users, which compared functionality, designer and accuracy of the output data. In all variables, the GerminaQuant was evaluated as superior compared to other spreadsheets available on the web. The full GerminaQuant package (for Windows(r), Macintosh(r) and Linux(r)) is freely available to the scientific community and can be easily downloaded from the website (http://www.ufpe.br/lev).

title: Germination inhibits the growth of new roots and seedlings in Eugenia uniflora and Eugenia brasiliensis

description: Abstract:Seeds of Eugenia species can produce new roots and whole plants even when much of its reserves is removed. However, new roots and seedlings rarely are formed spontaneously, and after cutting, each seed fragment usually produces only one new seedling, suggesting some control of the formation of several seedlings. It is possible, therefore, that germination leads to the production of inhibitory substances avoiding the development of new embryonic tissues. In the present work we have analyzed the potential of germinating seeds of Eugenia uniflora and Eugenia brasiliensisto inhibit new roots and seedling growth. Seeds were germinated after totally or partially fractionated. This last one was also totally fractionated after the development of a seedling, and the halves were also germinated. The results showed that the germination of the E. uniflora and E. brasiliensis seeds have inhibited the formation of new roots and seedlings.

title: The position of pronominal clitics in Brazilian Portuguese: the contribution of language perception investigation

description: Abstract: This paper aims to bring evidence – from the comparative analysis of investigations about the order of pronominal clitics based on Variationist Sociolinguistics and Experimental Phonology (VIEIRA, 2002; CORRÊA, 2009; 2012) – of the contribution of studies that combine description of linguistic production and perception, aided by speech resynthesis. Associating methodologies, the researches show that it is possible to define (i) the phonological direction of the unstressed pronouns, to the right (like pretonic syllables) or to the left (like post-tonic syllables); (ii) the acoustic parameters responsible for this direction; and, consequently, to specify, in sociophonetic terms, the characteristics which can be associated with certain structures and varieties.

title: Modeling and validation of a 3D premolar for finite element analysis

description: Abstract Introduction The development and validation of mathematical models is an important step of the methodology of finite element studies. Objective This study aims to describe the development and validation of a three-dimensional numerical model of a maxillary premolar for finite element analysis. Material and method The 3D model was based on standardized photographs of sequential slices of an intact premolar and generated with the use of SolidWorks Software (Dassault, France). In order to validate the model, compression and numerical tests were performed. The load versus displacement graphs of both tests were visually compared, the percentage of error calculated and homogeneity of regression coefficients tested. Result An accurate 3D model was developed and validated since the graphs were visually similar, the percentage error was within acceptable limits, and the straight lines were considered parallel. Conclusion The modeling procedures and validation described allows the development of accurate 3D dental models with biomechanical behavior similar to natural teeth. The methods may be applied in development and validation of new models and computer-aided simulations using FEM.

title: Diagrammatic reasoning: the art of good thinking to think about the greater good

description: Abstract Models are conceptual constructions, with some degree of simplification, that keep a partial match with the phenomena they aim to address. The Principialist model, which is based on a matrix formed by four principles: Beneficence, Non-Maleficence, Autonomy and Justice, stands out in the Bioethical field. When addressing a conflict between ethical guidelines, this model makes it possible to evaluate those guidelines that are more appropriate to the specific concrete situation. Based on the logical diagram, we sought to deepen the theoretical-conceptual foundation of bioethics, considering the standard Principialist model, which is an important heuristic tool. Logical relationships underlie all thoughts, and diagrams show such relationships in integrated spatial structures, representing the topology of concepts. The logical relationships, present in the structure of the models, allow one to understand the conceptual field of principles that operate within bioethical reasoning. The diagrammatic reasoning thus allows us to observe that, in the face of problem situations, there is no incompatibility between the Principialist and Personalist concepts - on the contrary, they complement one another and have synergy.

title: Decision support model applied to the recognition of non-adherent individuals to antihypertensive therapy

description: This study aimed at developing a decision-making support model to identify the individuals that do not adhere to the antihypertensive therapy. A decision tree is proposed to be applied on a database of treatment adherence involving 118 hypertensive patients from a Basic Unit of Health. The deciding variable was the adherence to the treatment. Among the variables related to the adherence, 15 predictor attributes were selected. The results arrived to a tree able to correctly classify 87,28% of the individuals. The decision tree model proposed helps in the recognition of non-adherent patients in a way to collaborate with health staff in approaching these individuals.

title: Validation of the Formal Quality Index as a model for assessing websites: The case of the local Portuguese e-Administration

description: Abstract The results derived from a content analysis applied to websites from 308 municipalities in Portugal are discussed. Despite the name of the method (which could possibly lead to confusion), the study has exclusively focused on the formal parameters of online communication; that is, audiovisual appearance, information architecture, usability, accessibility, and features of Web 2.0 present in the websites of the sample. As the main strategy for data processing, a Formal Quality Index was created from the computation of certain items in the codebook; a procedure adapted from previous research was satisfactorily replicated in the present study. This indicator was used to make interregional comparisons, which showed statistically significant differences, and it was also correlated with factors such as population, budget, purchasing power, or technological development of municipalities; all these were predictors of the formal status of the local Portuguese e-Administration.

title: Remoras and Spontaneous Echocardiographic Contrast

description: Abstract The term "Remora" (hindrance) - re (again)/mora (delay) -originally designated a family of fishes - the suckerfishes. In ancient Greece and Rome and up to the early 19th century, these fishes were believed to slow down ships by attaching to them. Medicine adopted the term "remora" to describe fluid/blood stasis. Intracardiac blood stasis, or remora, especially in the left atrial appendage, is associated with thrombogenesis and responsible for cardioembolic phenomena. The slow and swirling movement of blood causes the appearance of spontaneous echocardiographic contrast (SEC). I briefly narrate the Naval Battle of Actium, whose result was mythically attributed to the remora fishes, and make a short review of remoras. I also describe Laennec's discussion about intracardiac blood stasis and give a short account of SEC, its original descriptions and importance.

title: Biventricular Arrhythmogenic Cardiomyopathy: A New Paradigm?

description: Abstract Arrhythmogenic right ventricular dysplasia is a classic form of chronic myocardial disease with a broad phenotypical spectrum. We report an atypical case of a patient with biventricular arrhythmogenic cardiomyopathy. Although the current diagnosis criteria are the most widely accepted ones, they focus solely on the right ventricular phenotype. The use of late gadolinium enhancement in cardiac magnetic resonance in this patient was essential for the diagnosis and assessment of the left ventricular involvement extent. This tool allows a broader use of current diagnosis criteria for this disease.

title: Comparative analysis of niobium and vanadium carbide efficiency in the high energy mechanical milling of aluminum bronze alloy

description: Abstract This study aims to analyze the efficiency of niobium and vanadium carbides in the high energy mechanical milling of aluminum bronze alloy. Two series of experiments were made following the same steps for both niobium carbide (NbC) and vanadium carbide (VC) additions: 30 g of chips were weighed and placed in a stainless steel jar with 3 % of carbide and 1 % of stearic acid for a mass/sphere relationship of 1:10. The milling was realized using a planetary ball mill for 10, 30 and 50 hours in an inert argon atmosphere at 300 rpm. Results shown in laser diffraction indicate a great reduction in the particle sizes of powders when VC is used. For 30 hours milling, D50 values ranged from 1580 µm with NbC to 182.3 µm with VC addition. The D50 values ranged from 251.5 µm with NbC to 52.26 µm with VC addition, for 50 hours milling. The scanning electron microscopy showed that in 10 hours of milling, the energy was not sufficient to achieve the shear of chips in both cases. For 30 hours, it's possible to observe particles with sizes between 100 µm and 800 µm with NbC addition while for the same milling time, with VC it's possible to see particles with different sizes, but with many shapes of fine particulates. For 50 hours milling, particles achieved the smaller sizes between 50 and 200 µm with NbC and ranging from 5 until 50 µm with VC addition.

title: WATERMELON YIELD AND EFFICIENCY OF USE OF WATER AND NITROGEN

description: ABSTRACT The evaluation of the yield of crops and their efficiency of use of water and nitrogen is essential to optimize the management of production factors. The objective of this study is to evaluate the effect of irrigation regimes and nitrogen doses in fertigation on fruit yield and efficiency of use of water and nitrogen by the Top Gun watermelon hybrid. The study was conducted in Bom Jesus, Piauí, Brazil, from August 4 to October 15, 2015. The study used a completed randomized block design with four repetitions, five irrigation depths (110.17, 156.86, 221.16, 268.87, and 317.09 mm), and five doses of nitrogen in fertigation (0, 50, 100, 150, and 200 kg ha-1 applied as urea). Fruit yield and water use efficiency were not affected by nitrogen doses; however, there was a significant interaction of the factors for the efficiency of nitrogen use. The highest yield (39,549.45 kg ha-1) was obtained using 233.48 mm of water during the growth cycle. The water depth that promoted the maximum efficiency of water use was 110.42 mm, and nitrogen use was most efficient using 232.21 mm of water and 50 kg ha-1 of nitrogen.
