title: Numerical Simulation of the Wake Structure and Thrust/Lift Generation of a Pitching Airfoil at Low Reynolds Number Via an Immersed Boundary Method

description: ABSTRACT: In this study, an accurate computational algorithm in the context of immersed boundary methods is developed and used to analyze an incompressible flow around a pitching symmetric airfoil at Reynolds number (Re = 255). The boundary conditions are accurately implemented by an iterative procedure applied at each time step, and the pressure is also updated simultaneously. Flow phenomena, observed at different oscillation frequencies and amplitudes, are numerically modeled, and the physics behind the associated vortex dynamics is explained. It is shown that there are four flow regimes associated with four wake structures. These include three symmetric flow regimes, with adverse, favorable and no vortex effects, and an asymmetric flow regime. The phenomena associated with these flow regimes are discussed, and the critical or transitional values of the Strouhal (St) and normalized amplitude (AD) numbers are presented. It is shown that, at the fixed pitching amplitude, AD = 0.71, the transition from adverse (drag generation) to favorable (thrust generation) symmetric flow regime occurs at St = 0.23. Moreover, at this particular amplitude, transition from symmetric to asymmetric regime occurs at St = 0.48. It is also shown that, at St = 0.22, the wake is always deflected and the flow is asymmetric for large enough amplitudes AD &gt; 2. The dipole vortices and lift generation are two characteristics of asymmetric vortex street. This numerical study also reveals that the initial phase angle has a dominant effect on the appearance of dipole vortices and vortex sheet deflection direction. Numerical results are in good agreement with the available experimental data.

title: RECONFIGURATION OF THE LANDSCAPE IN THE AMAZONIAN SAVANNAS

description: ABSTRACT The occupation process of the savannahs in Roraima which is reflected in an outstanding way in the modification of its landscapes. This study is aimed at analyzing the expansion of agricultural activities and the changes to the landscapes of the savannas in the municipality of Boa Vista (RR), known by the local name "Lavrado", between the years 2000 and 2014. To reach the objectives, the methodology of Environmental Analysis by Geoprocessing, was adopted, with diagnostic procedures such as inventories, signatures, and environmental assessments. The results indicated that intensification of the use and modification of land cover, occurring in the production of grains (soybean), is occurring. The historical process of occupation and intensification of use occurred as a result of the actions of the State, like the measures of the state government, which guide its strategies in the strengthening of agriculture and livestock. In this scenario, the conversion of the savannas became strategic to the productive process, like that which occurred in the Cerrado biome of Central Brazil, mainly during the 1970s.

title: VERSES IN MACHADO DE ASSIS’S COMPLETE POETRY

description: Abstract This paper surveys the verses employed by Machado de Assis in his four published poetry books. When Machado grouped his first three books of poetry, Crisálidas (1864), Falenas (1870) and Americanas (1875), with his fourth book, Ocidentais, in his Poesias completas (1901), the poet removed several poems from the first three books. This paper compares the verses that were kept in Poesias completas with those cut out of the collection. A comparative approach is also taken in studying the verses used in the four books in their definitive forms. The objective of this analysis is to show the prominent verses in each book over the course of the poet’s career.

title: Amplification of DNA Brownian Motion Using Electrokinetic Noise

description: This dataset was collected to study the effects of applied white Gaussian electrokinetic noise on the diffusivity of single DNA molecules inside a nanofluidic slit. Our raw data consists of image sequences in FITS format (Flexible Image Transport System). Each image shows a fluorescent Lambda DNA molecule stained by YOYO-1 dye at a 10:1 base-pair to dye ratio diffusing inside a 110 nm deep nanoslit under specified amounts of applied noise. An imaging system comprising an inverted Nikon TE2000U microscope, an ANDOR iXon 897 EMCCD camera, an X-Cite UV illumination system, and a 60X, 0.7 NA, water-immersion objective lens with an extra 1.5X magnification factor was used to acquire the images. We applied 8 different noise intensities and recorded about 50-70 molecules per noise intensity. These data can be used to find trajectories of the centers of mass of the molecules and to analyze the radii of gyration and DNA shapes. Sigma represents the standard deviation of the applied Gaussian noise.

title: Efficacy of passive ultrasonic irrigation in removing root filling material during endodontic retreatment

description: Abstract Introduction The aim of endodontic retreatment is to remove the previous root filling materials completely to allow for the subsequent steps of cleaning, canal shaping and filling replacement. Objective To evaluate the efficacy of passive ultrasonic irrigation (PUI) in the removal of residual root filling material after removing the bulk of the root filling with nickel-titanium rotary instruments. Material and method Eighteen mesial isthmus-containing roots of human mandibular molars were prepared and filled. The root canal filling was removed with the ProTaper Retreatment system and K-files. The specimens were randomized into 2 groups (n = 9), both irrigated with 2.5% NaOCl and 17% EDTA. In the conventional group, an irrigation syringe was used. In the PUI group, the PUI technique was used. The roots were sectioned longitudinally and evaluated under stereomicroscopy. Student’s t test was used to compare groups and the general linear model was used to compare the apical, cervical, and middle root thirds within each group, in regard to the percentages of remaining residual filling material. Result There was no statistically significant intergroup difference, irrespective of which root third was evaluated (P &gt; 0.05). In the PUI group, the apical third showed a significantly higher percentage of residual filling material, in comparison with the cervical (P = 0.038) and middle (P = 0.029) thirds. Conclusion The PUI technique was not more effective than the conventional irrigation technique in removing residual root filling material during endodontic retreatment in root canals with a complex anatomy.

title: Training watershed committee members to aid on the decision-making process for the execution program of the framework of water bodies

description: ABSTRACT According to the National Water Resources Council 91/2008, the approval of the action plan of the framework of water bodies should be carried out through a decision-making process along the participation of the Watershed Committee (CBH). However, decision-making processes involving multiple stakeholders are vulnerable to flaws that can lead to mistrust among members and lack of commitment with the decisions taken. Some of these failures refer to the absence of information, transparency and lack of knowledge of the object of decision. In this context, the use of technological tools as a means to expand social participation has increased considerably. Among these, it is possible to mention the Information and Communication Technologies (ICTs). This paper presents a study about the use of Information and Communication Technologies (ICTs) to aid watershed committee members on deciding about the set of actions for the execution of the framing of water bodies, having the Salitre River Watershed as a study case. To support the decision on selecting the best action plan the Analytic Hierarchy Process (AHP) multi-criteria analysis method was used, for which a Distance Learning course (DL) within the free platform of “facebook” was developed. The analysis of the results showed that through the expansion of online communication and the creation of open forums through websites and social networks, the discussions among the watershed committee members may extend beyond the plenary meetings that occur not very often throughout the year. The application of ICTs presented some advantages regarding to the decision-making process within the CBH, such as: more time to discuss and obtain consensus; increasing access and exchange of information and experiences; transferring of technical information more clearly; and solving problems like inability to travel by the CBH members.
