Projeto Político-Pedagógico: uma possibilidade de gestão democrática
Authors: Costa Daianny Madalena 
Published: April 2017

Neste artigo, partimos da promulgação da Constituição Federal (1988), enquanto um marco a favor da democracia, a qual estabeleceu a educação como direito social (art 6º), que visa o pleno desenvolvimento humano (art. 205) e que tem a gestão democrática como princípio (art. 206, VI). Dela decorreu o conjunto de legislações posteriormente. Porém, por mais que uma lei aponte para um fim, é inegável a participação da sociedade para que efetivamente se consolide. Assim, por meio de uma metodologia dialógica, entre ação-reflexão-ação, analisaremos a construção dos projetos políticos-pedagógicos (PPPs) enquanto uma possibilidade viável de gestão democrática, realizada numa rede municipal de educação, de uma cidade da região Metropolitana do Vale do Paraíba, no estado de São Paulo. Bobbio (1986) afirma que “para o regime democrático, o estar em transformação é seu Estado natural: a democracia é dinâmica, o despotismo é estático e sempre igual a si mesmo” (p. 9). Desse modo, buscar princípios democráticos, significa compreendê-los em transformação e permanente negação aos autoritarismos e despotismos que fazem parte dos jogos do poder. Consideramos, portanto, que os PPPs podem ser a proposta enunciada para um planejamento participativo e democrático e, ao mesmo tempo, seu guardião. Ou seja, da mesma forma que o convite realizado para sua preparação seja por meio de uma construção coletiva, democrática e participativa, a gestão democrática será pautada enquanto “um capítulo”, construída no cerne do documento, que remeta a uma constante apropriação, amadurecimento e sustentação da vida escolar como princípio democrático.

Authors: Carvalho Filho Josué José de , Brasileiro Tânia Suely Azevedo 
Published: April 2017

Este artigo e parte de uma dissertação de mestrado e traz reflexões sobre o Estágio Curricular Supervisionado na Amazônia. Com isso, o objetivo consistiu em analisar o estágio curricular supervisionado na formação do professor de Educação Física em uma IFES da região norte, levando em consideração seu currículo. A pesquisa foi descritiva/qualitativa, a partir de um estudo de caso no curso de Educação Física da UNIR. O marco teórico adotado dialogou com autores como: Bianchi, Alvarenga e Bianchi (2009), Contreras (2012), D’Avila (2013), Dourado (2015), Libâneo (2013), Pimenta (2012a, 2012b), Pimenta e Lima (2011) e Veiga (2010, 2004), entre outros que discutem a temática abordada. Os participantes e instrumentos do estudo foram dois docentes, um deles foi coordenador de curso e o outro o supervisor de estagio, e quatorze discentes, sendo aplicação de entrevista aos primeiros e questionário semiestruturado com os segundos. O tratamento e discussão das informações coletadas se deram à luz da análise de conteúdos de Bardin (2009). Os resultados revelaram que o estágio na formação do professor de Educação Física contribui para a mobilização de saberes e implica na decisão em “ser ou não ser” um professor. Trata-se, portanto, de uma proposta de estágio realimentada pelos sujeitos que vivem a teoria e a prática a partir do currículo vivido, pela profissão exercida e pelo compromisso com o futuro campo de trabalho.

BONE MARROW HOMING AND ENGRAFTMENT DEFECTS OF HUMAN HEMATOPOIETIC STEM AND PROGENITOR CELLS
Authors: Caocci Giovanni , La Nasa Giorgio 
Published: April 2017

Homing of hematopoietic stem cells (HSC) to their microenvironment niches in the bone marrow is a complex process with a critical role in repopulation of the bone marrow after transplantation. This active process allows for migration of HSC from peripheral blood and their successful anchoring in bone marrow before proliferation. The process of engraftment starts with the onset of proliferation and must therefore be functionally dissociated from the former process. In this overview we analyse the characteristics of stem cells (SCs) with particular emphasis on their plasticity and ability to find their way home to the bone marrow. We also address the problem of graft failure which remains an important contributor to morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). Within this context, we discuss non-malignant and malignant hematological disorders treated with reduced intensity conditioning regimens or grafts from human leukocyte antigen (HLA)-mismatched donors.
Swiss International School Dubai: Design and simulation of a Minergie building in Dubai
Authors: Bourdoukan Paul 
Published: April 2017

Minergie is a Swiss quality label for buildings developed to ensure comfort, low energy consumption, and healthy indoor environment. It was introduced in 1995, and, today, about 30% of new buildings are Minergie compliant. The campus of the Swiss International Scientific School of Dubai (SISD) is designed to be Minergie compliant. The campus includes a primary school building, an administrative building, a middle high school (MHS)–library–auditorium building, a sport center, and a boarding house. The primary and the administrative building are built. The sport center is under construction while the MHS building is under development.Except the sport center, the campus is designed to be Minergie compliant. SORANE SA, along with the design team, conducted the preliminary design of primary school and administrative building to be Minergie compliant. We are currently assisting the design team of the MHS, the library and the auditorium building to achieve Minergie certification.The design is based on achieving comfort and low energy demand through efficient sun protection, highly insulated and tight envelope, heat and moisture recovery on the ventilation system, as well as optimized daylighting of the occupied space.The primary school building and the administrative building were built and are the first buildings to be certified as Minergie in the Middle East. The simulation of the primary school building showed that the building following the Minergie standards consumed 80% less than a conventional building in Dubai. Moreover, the building ensured a healthy indoor environment, with stable thermal, visual comfort, and low draught conditions due to the low speed ventilation. More importantly, designing the school following the Minergie requirements did not increase the systems' complexity, but rather resulted in low energy demand that reduced the size of the installations.In this paper, we describe the design procedure of the buildings from the energy perspective and the challenges that we faced to achieve Minergie certification. Advanced simulations were performed to design the envelope and HVAC systems in order to minimize energy consumption. Daylight calculations and dynamic thermal simulations are also discussed in detail. First, the Minergie label is described briefly, followed by the description of its prerequisites and energy targets. Then, the building envelope design procedure is presented. Finally, the HVAC system design is detailed, and the simulation results of the building consumption are presented.

Published: April 2017

AbstractReal‐time assessment of the state of a volcano plays a key role for civil protection purposes. Unfortunately, because of the coupling of highly nonlinear and partially known complex volcanic processes, and the intrinsic uncertainties in measured parameters, the state of a volcano needs to be expressed in probabilistic terms, thus making any rapid assessment sometimes impractical. With the aim of aiding on‐duty personnel in volcano‐monitoring roles, we present an expert system approach to automatically estimate the ongoing state of a volcano from all available measurements. The system consists of a probabilistic model that encodes the conditional dependencies between measurements and volcanic states in a directed acyclic graph and renders an estimation of the probability distribution of the feasible volcanic states. We test the model with Mount Etna (Italy) as a case study by considering a long record of multivariate data. Results indicate that the proposed model is effective for early warning and has considerable potential for decision‐making purposes.
Mineralogy and stratigraphy of the Gale crater rim, wall, and floor units

Published: April 2017

AbstractThe Curiosity rover has detected diverse lithologies in float rocks and sedimentary units on the Gale crater floor, interpreted to have been transported from the rim. To understand their provenance, we examine the mineralogy and geology of Gale's rim, walls, and floor, using high‐resolution imagery and infrared spectra. While no significant differences in bedrock spectral properties were observed within most Thermal Emission Imaging System and Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) scenes, some CRISM scenes of rim and wall rocks showed olivine‐bearing bedrock accompanied by Fe/Mg phyllosilicates. Hydrated materials with 2.48 μm absorptions in Gale's eastern walls are spectrally similar to the sulfate unit in Mount Sharp (Aeolis Mons). Sedimentary strata on the Gale floor southwest of the landing site, likely coeval with the Bradbury units explored by Curiosity, also are hydrated and/or have Fe/Mg phyllosilicates. Spectral properties of these phyllosilicates differ from the Al‐substituted nontronite detected by CRISM in Mount Sharp, suggesting formation by fluids of different composition. Geologic mapping of the crater floor shows that the hydrated or hydroxylated materials are typically overlain by spectrally undistinctive, erosionally resistant, cliff‐forming units. Additionally, a 4 km impact crater exposes >250 m of the Gale floor, including finely layered units. No basement rocks are exposed, thus indicating sedimentary deposits ≥250 m beneath strata studied by Curiosity. Collectively, the data indicate substantial sedimentary infill of Gale crater, including some materials derived from the crater rim. Lowermost thin layers are consistent with deposition in a lacustrine environment; interbedded hydrated/hydroxylated units may signify changing environmental conditions, perhaps in a drying or episodically dry lake bed.
On the feasibility and use of teleseismic P wave coda autocorrelation for mapping shallow seismic discontinuities
Authors: Phạm Thanh‐Son , Tkalčić Hrvoje 
Published: April 2017

AbstractSeismic body waves from distant earthquakes, which propagate near vertically beneath recording stations, provide tools for imaging shallow Earth structures with high vertical resolution. The most commonly used techniques such as P and S wave receiver functions utilize mode conversions from P to S waves or vice versa to retrieve information on the gradients of elastic properties in the crust and upper mantle. Here we demonstrate the feasibility and advantage of utilizing reflection signals through an improved method of teleseismic P wave coda autocorrelation. We recover clear reflections independently on vertical and radial components, which provide complementary constraints on the subsurface structures. Field data from two stations from different geological settings are analyzed, one of which is an ice station in Antarctica and the other is a bedrock station on the Kaapvaal craton in South Africa. The results from both analyses show the feasibility of the method to unveil P and S wave reflection signals from the ice‐rock interface and the Moho discontinuity. Extensive synthetic experiments are set up to corroborate our results.
Improving climate projections by understanding how cloud phase affects radiation
Authors: Cesana Gregory , Storelvmo Trude 
Published: April 2017

AbstractWhether a cloud is predominantly water or ice strongly influences interactions between clouds and radiation coming down from the Sun or up from the Earth. Being able to simulate cloud phase transitions accurately in climate models based on observational data sets is critical in order to improve confidence in climate projections, because this uncertainty contributes greatly to the overall uncertainty associated with cloud‐climate feedbacks. Ultimately, it translates into uncertainties in Earth's sensitivity to higher CO2 levels. While a lot of effort has recently been made toward constraining cloud phase in climate models, more remains to be done to document the radiative properties of clouds according to their phase. Here we discuss the added value of a new satellite data set that advances the field by providing estimates of the cloud radiative effect as a function of cloud phase and the implications for climate projections.
The primacy of doubt: Evolution of numerical weather prediction from determinism to probability
Authors: Palmer Tim 
Published: April 2017

AbstractOver the last 25 years, the focus of operational numerical weather prediction has evolved from that of estimating the most likely evolution of weather to that of estimating probability distributions of future weather associated with inevitable uncertainties in both initial conditions and model equations. This evolution from determinism to uncertainty has not only increased the scientific rigor of weather prediction, it has also increased the value of weather forecasts for users. In addition, it has opened up a new approach to solving the equations of motion, likely to be of importance for both weather and climate prediction in an age where high‐performance computing is limited by power consumption. However, despite all this, the numerical weather prediction community has yet to embrace fully the concept of the primacy of doubt. It is now time to take the final step in this direction.
The importance of international collaboration in space research
Authors: Greenwald Raymond A. 
Published: April 2017

AbstractOver the past four decades, international collaborations in space plasma science have led to rapid growth in our understanding of the physical processes that control the transport of energy and plasma through the Earth's magnetosphere‐ionosphere system and the processes that transfer energy from the solar wind to the Earth's magnetosphere. These collaborations have also enabled more complex missions to be flown and more multipoint observations to be made in both the magnetosphere and ionosphere. In this commentary, we present some examples of these collaborations and discuss how they have improved our understanding of the Earth's plasma environment.
Slamming
Authors: Faltinsen Odd M. 
Published: April 2017

AbstractSlamming associated with external ship flow, green water on ship decks, and sloshing in ship tanks is discussed. A brief overview of relevant numerical and theoretical hydrodynamic methods is given. Verification and validation are emphasized. It is advocated that slamming must be coupled with structural mechanics in order to find important timescales of the many physical effects associated with slamming and in order to make proper simplifications. Hydroelasticity may matter for both local and global slamming effects. Experimental drop results of horizontal elastic plates show no correlation between maximum slamming pressure and maximum stresses, that is, if the timescale of slamming impact is very small relative to the structural natural periods associated with maximum structural stress, hydrodynamic details do not matter. Both water‐entry and exit phases matter in describing the global wetdeck slamming effects. The influence of gas cavity oscillations and nonviscous flow separation (ventilation) is discussed. Sloshing‐induced slamming in prismatic liquefied natural gas tanks is perhaps the most complicated slamming problem within marine applications because many fluid mechanic and thermodynamic parameters as well as hydroelasticity may have influence. Furthermore, violent sloshing causes complicated in‐flow scenarios of slamming. The consequence is that both computational tools and model‐test scaling are limited.
Flow Around Ships and Underwater Vehicles
Authors: Iafrati Alessandro 
Published: April 2017

AbstractIn this contribution, some aspects of the flow generated by surface or underwater vehicles are discussed. The content is a synthetic review of the literature in the field. The basic features, which are already well established, are briefly recalled, whereas attention is mainly devoted to the most recent research advances on those hydrodynamic phenomena that are not yet fully understood or are at the research frontier of the field. These are the breaking of the bow wave and the subsequent vorticity generation, the separated turbulent flow at the stern, the effect of the scale on the flow characteristics, the flow about propellers and the mutual interaction of the propeller with ship hull and rudders, and the flow about ships in maneuver or in unsteady motion. For underwater vehicles, the discussion concerns the flow generated by a submarine in steady motion in open water or close to the free surface, the flow about the propeller and the interaction with hull, sail, and rudder. Finally, some considerations are given for supercavitating vehicles.
Wave and Crest Height Distributions
Authors: Forristall George Z. 
Published: April 2017

AbstractWave measurements, forecasts, and hindcasts generally describe waves by their power spectrum. However, information on individual wave and crest heights is needed in many applications. In this article, we describe methods for estimating wave and crest height distributions based on the information contained in the spectrum. A first‐order description is sufficient for trough to crest wave heights because the second‐order correction raises both crest and trough. For good accuracy, it is, however, necessary to account for the variation in the wave envelope between trough and crest. Second‐order theory gives a good approximation to nonlinearity crest heights. Equations for practical calculation of all the distributions are listed. Finally, we consider the evidence that physics beyond second order are necessary to account for extremely large waves, often called rouge or freak waves.
Geophysical Techniques for Offshore Site Investigation
Authors: Tyler Steve , Vanneste Maarten , Butler David 
Published: April 2017

AbstractGeophysics is an essential tool for the detection and understanding of variations in the properties of the Earth, geological structure, and for the identification of potential geohazards. The understanding of the geology and geological processes active within an area can have significant implications for locating infrastructure, for safety in its design and design optimization, and for potential time and cost savings associated with its installation. In‐depth knowledge of the active geological processes will also provide added confidence in the success of engineering projects over their operational lives.The advantage of using geophysical techniques in the marine environment is that large areas of the seafloor can be mapped relatively easily and in a relatively short time. Geotechnical boreholes are an effective means of investigating subsurface shallow geology but are expensive to conduct and only provide information at discrete locations. Nevertheless, boreholes (and wells) are essential to provide calibration and ground truthing of geophysical data.The applications of marine geophysics are as varied as the techniques and instruments that have been developed for surveying the sea floor. In the context of engineering, marine geophysics is an essential component of data integration and the development of a detailed geological model. The platforms from which data are acquired have evolved rapidly. Survey vessels are still the mainstay of site investigations but there is now much greater utilization of vehicles such as autonomous underwater vehicles (AUVs) to acquire data with higher resolution.The properties required to be measured, accurate positioning and coverage, adequate penetration, and sufficient resolution of geophysical data are of primary concern when planning and executing a geophysical survey.Seafloor variability is typically mapped using acoustic techniques such as echo sounding, side scan sonar, and seismic reflection. Subseafloor variability is most commonly mapped using seismic reflection methods, and to a lesser degree with magnetic methods, seismic refraction, seismic converted waves and shear waves, electrical methods, and electromagnetic methods. The various geophysical techniques yield complementary information, and as such there is a trend toward multidisciplinary approaches for obtaining improved seafloor and seabed characterization. The subsequent processes of integration and interpretation of these datasets is essential to the development and refinement of a geological model, which can be applied to engineering requirements.
