La aproximación o la divergencia entre aprendizaje en la escuela y la actividad profesional, siempre es un tema recurrente en la docencia de Proyectos. Si bien es cierto que las metodologías docentes no tienen por qué coincidir con objetivos profesionales, este hecho y su acumulación durante los sucesivos cursos de Proyectos, hacen que la divergencia sea la gran protagonista en esta controversia. Con el objetivo de aproximar estas dos situaciones, se ha planteado un curso de Proyectos en el que mediante el trabajo en equipo y la búsqueda de sinergias entre distintos grados universitarios (Grado en Arquitectura de la Universidad Politécnica de Cartagena, y Grado en Publicidad y Relaciones Públicas de la Universidad de Murcia) y diferentes agentes sociales se puedan compatibilizar y converger. Todo ello, enmarcado en un convenio con el Excmo. Ayuntamiento de Alhama de Murcia, a través de un Proyecto de Innovación Docente.
The approximation or the divergence between the learning at university and the professional activity is always a recurrent issue in Project teaching. Although it is true that the teaching methodologies don’t have to coincide with professional objectives, this fact and its accumulation during the successive courses of Projects, make that the divergence is the great protagonist in this controversy. With the aim of approaching these two situations, a Project course has been proposed in which, through teamwork and the search for synergies between different university degrees (Degree in Architecture of the Universidad Politécnica de Cartagena, and Degree in Advertising and PR of the Universidad de Murcia) and different social agents can be compatible and converge. All this, framed in an agreement with the Alhama de Murcia Council, through a Teaching Innovation Project.
Batismo de Sangue: literatura testemunhal como ferramenta do reconhecimento histórico da dor.
Authors: Rovai Marta Gouveia de Oliveira , Teixeira Eduardo Augusto Carvalho 
Published: November 2017

Resumo: Este artigo discute e busca compreender a literatura de testemunho como fonte histórica importante para o entendimento da ditadura civil-militar e do processo de redemocratização no Brasil, por meio da obra do Frei Carlos Alberto Libânio Christo, o Frei Betto, intitulada Batismo de Sangue e publicada em 1982. Entende-se que as produções testemunhais de sobreviventes de grandes catástrofes não são reflexos da realidade, mas produtos históricos de uma sociedade específica e de agentes discursivos que interferem no próprio processo histórico, como o gênero testemunhal. A adoção de perspectivas e linguagens diferenciadas sobre a leitura do passado, o possível choque de conteúdos e interpretações entre a memória coletiva de militância de grupos distintos e a construção da memória relativa à participação de setores da Igreja Católica na resistência armada ao regime militar são preocupações abordadas neste texto. Palavras chave: Batismo de Sangue – ditadura – literatura - testemunho – dominicanos Abstract: This article discusses and seeks the comprehension of witness testimony as an important historical source to understand the civil-militar dictatorship and the process of democratization of Brazil, through the literary work of the priest Carlos Alberto Libânio Christo, Frei Betto, called Batismo de Sangue, published in 1982. It is understood that the testimonial productions of survivors of great catastrophes, aren’t the reflexes of reality, but the historical products of a specific society and of discursive agents that interfere in the historical process itself, as a testimonial gender. The choice of perspectives and different languages about the analysis of the past, the possible shock of interpretations and contents between the collective memory of militancy of different groups and the construction of relative memory to the participation of sectors of the Catholic Church in the armed resistence to the military regime are some of the concerns addressed in this article.

Leukemias are malignant neoplasms that affect blood cells and originate in bone marrow. These are cancers of high incidence and are difficult to treat and there is a constant search for more efficient therapies. The present work investigated the cytotoxic action of the hydroalcoholic extract of Croton urucurana in human leukemia cells U937 and THP-1. The U937 and THP-1 cell lines were plated in a 100 μL/well volume (1x106 cells/mL) in 96-well plates, treated with extracts at final concentrations of 50 μg/mL, 100 μg/mL, 200 μg/mL and 400 μg/mL and 800 μg/mL for cell viability tests with MTT(-3- (4.5-dimethyl-2-thiazole) 2.5-diphenyl-2H-tetrazolium bromide). After 48h, viability was assessed by MTT and the supernatant was used for determination of the Lactate Dehydrogenase (LD) enzyme. Fluorescence microscopy was used to evaluate apoptosis. The extract was able to reduce cell viability by the MTT assay, increase LD release and induce apoptosis in both cell lines tested at concentrations of 400 and 800 μg/ mL (p≤0.05). The C. urucurana extract presented cytotoxic activity against human leukemic cell lines U937 and THP-1, presenting itself as promising in the search for new antineoplastic agents.

The portion of the Hydrographic Region of Uruguay River situated between the Rio Grande do Sul and Santa Catarina states are being evaluated as potential of hydric resources for hydroeletric enterprises. The City of Erechim is located between the coordinates 27° 29’ 20” S; 52° 10’ 03”W and 27° 47’ 15”S; 52° 21’ 52” W, northwest region of the state, is part of the volcanic spills of the Serra Geral Formation, Fácies Paranapanema in the Paraná basin. The uses of ground waters in the Hydrografic Region of Uruguay are multiple: human, animal supplying, hydrothermal waters, irrigation, mineral water bottling. However, the risk of contamination of ground waters comes together with its growing demand, fact that indicates the necessity of this resource management. This work has as objective to evaluate and to spatialize in cartograms GOD system for evaluation of aquifer pollution vulnerability of the Serra Geral Aquifer System/SASG, forming one unconfined fissural aquifer at outcrops near surface. Of a total of 99 tubular wells registered in cadastre in the System of Ground Water Information SIAGAS/CPRM, the GOD system for evaluation ofaquifer pollution vulnerability was applied in 55 wells. The cartograms had been generated in the software 8.0 Surfer and ArcGIS 9.3, represented in the Universal System Transversa de Mercator/UTM. The GOD system for evaluation of aquifer pollution vulnerability showed 47 wells inserted in the class of average vulnerability, representing about 85.5% of the total area evaluated of 430.76 km ². The class low occupied 12.7% of the area and only 1.8% were inserted in the negligible class. The layer of variation of the potenciometric quota was between 416 and 780 meters, being observed the occurrence of high regional potenciometrics and low potenciometrics locals. The regional direction of underground flow was in the direction southeast - northeast, for the gutter of the Uruguay River. .

This work aimed to evaluate the biogas production potential of swine manure (SM) under different temperatures through the use of experimental biodigesters (EB), investigating the physical, chemical and microbiological parameters of the process. The experiment consisted of three treatments a) with solid fraction separation (WSSF), b) without solid fraction separation (W-SSF) and c) solid fraction only (OSF). The assays were performed in triplicate and submitted to room temperature (RT) (13.36 to 23.71° C) and to controlled temperature (30.00ºC), during 28 days. The average biogas production in the EB was 390.41 ml (WSSF), 390.53 ml (W-SSF) and 400.53 ml (OSF), at RT and 393.00 ml (WSSF), 393.00 ml (W-SSF) and 390.67 ml (OSF) at 30.00ºC. The results showed that significant differences occurred in the biogas production due to the different treatments and temperatures. The highest average reduction of parameters as a function of treatment and temperature was 53.22% for total solids in WSSF (30°C), 10.73% for nitrogen in W-SSF (RT), 27.50% for phosphorus in the WSSF (TA), 63.55% for the COD in the W-SSF (TA), 99,10% for the total coliforms in the W-SSF (TA) and 99.59% for the thermotolerant coliforms in the WSSF (30°C).
High‐Resolution Dynamical Downscaling Ensemble Projections of Future Extreme Temperature Distributions for the United States

Published: November 2017

AbstractThe aim of this study is to examine projections of extreme temperatures over the continental United States (CONUS) for the 21st century using an ensemble of high spatial resolution dynamically downscaled model simulations with different boundary conditions. The downscaling uses the Weather Research and Forecast model at a spatial resolution of 12 km along with outputs from three different Coupled Model Intercomparison Project Phase 5 global climate models that provide boundary conditions under two different future greenhouse gas (GHG) concentration trajectories. The results from two decadal‐length time slices (2045–2054 and 2085–2094) are compared with a historical decade (1995–2004). Probability density functions of daily maximum/minimum temperatures are analyzed over seven climatologically cohesive regions of the CONUS. The impacts of different boundary conditions as well as future GHG concentrations on extreme events such as heat waves and days with temperature higher than 95°F are also investigated. The results show that the intensity of extreme warm temperature in future summer is significantly increased, while the frequency of extreme cold temperature in future winter decreases. The distribution of summer daily maximum temperature experiences a significant warm‐side shift and increased variability, while the distribution of winter daily minimum temperature is projected to have a less significant warm‐side shift with decreased variability. Using “business‐as‐usual” scenario, 5‐day heat waves are projected to occur at least 5–10 times per year in most CONUS and ≥95°F days will increase by 1–2 months by the end of the century.
Mantle Flow as a Trigger for Subduction Initiation: A Missing Element of the Wilson Cycle Concept
Authors: Baes M. , Sobolev S.V. 
Published: November 2017

AbstractThe classical Wilson Cycle concept, describing repeated opening and closing of ocean basins, hypothesizes spontaneous conversion of passive continental margins into subduction zones. This process, however, is impeded by the high strength of passive margins, and it has never occurred in Cenozoic times. Here using thermomechanical models, we show that additional forcing, provided by mantle flow, which is induced by neighboring subduction zones and midmantle slab remnants, can convert a passive margin into a subduction zone. Models suggest that this is a long‐term process, thus explaining the lack of Cenozoic examples. We speculate that new subduction zones may form in the next few tens of millions of years along the Argentine passive margin and the U.S. East Coast. Mantle suction force can similarly trigger subduction initiation along large oceanic fracture zones. We propose that new subduction zones will preferentially originate where subduction zones were active in the past, thus explaining the remarkable colocation of subduction zones during at least the last 400 Myr.

AbstractWe present statistical results from the Cassini Radio and Plasma Wave Science (RPWS) Langmuir probe measurements recorded during the time interval from orbit 3 (1 February 2005) to 237 (29 June 2016). A new and improved data analysis method to obtain ion density from the Cassini LP measurements is used to study the asymmetries and modulations found in the inner plasma disk of Saturn, between 2.5 and 12 Saturn radii (1 RS=60,268 km). The structure of Saturn's plasma disk is mapped, and the plasma density peak, nmax, is shown to be located at ∼4.6 RS and not at the main neutral source region at 3.95 RS. The shift in the location of nmax is due to that the hot electron impact ionization rate peaks at ∼4.6 RS. Cassini RPWS plasma disk measurements show a solar cycle modulation. However, estimates of the change in ion density due to varying EUV flux is not large enough to describe the detected dependency, which implies that an additional mechanism, still unknown, is also affecting the plasma density in the studied region. We also present a dayside/nightside ion density asymmetry, with nightside densities up to a factor of 2 larger than on the dayside. The largest density difference is found in the radial region 4 to 5 RS. The dynamic variation in ion density increases toward Saturn, indicating an internal origin of the large density variability in the plasma disk rather than being caused by an external source origin in the outer magnetosphere.
Ion Friction and Quantification of the Geomagnetic Influence on Gravity Wave Propagation and Dissipation in the Thermosphere‐Ionosphere
Authors: Medvedev Alexander S. , Yiğit Erdal , Hartogh Paul 
Published: November 2017

AbstractMotions of neutrals and ions in the thermosphere‐ionosphere (TI) do not, generally, coincide due to the presence of the geomagnetic field and associated electromagnetic forces affecting plasma. Collisions of ions with gravity wave (GW)‐induced motions of neutrals impose damping on the latter. We derive a practical formula for the vertical damping rate of GW harmonics that accounts for the geometry of the geomagnetic field and the direction of GW propagation. The formula can be used in parameterizations of GW effects developed for general circulation models extending from the lower atmosphere into the mesosphere and thermosphere. Vertical damping of GW harmonics by ion‐neutral interactions in the TI depends on the geometry of the geomagnetic field but not the strength of the latter. The ion damping of harmonics propagating in the meridional direction (in the geomagnetic coordinates) maximizes over the poles and reduces to zero over the equator. Waves propagating in the zonal direction are uniformly affected by ions at all latitudes. Accounting for the anisotropy produces changes in the GW drag in the F region of more than 100 m s−1 d−1, cooling/heating rates of more than 15 K d−1, and in GW temperature variance of disturbances by more than 5 K.
The Influence of Sediment Isostatic Adjustment on Sea Level Change and Land Motion Along the U.S. Gulf Coast

Published: November 2017

AbstractSea level rise presents a hazard for coastal populations, and the Mississippi Delta (MD) is a region particularly at risk due to the high rates of land subsidence. We apply a gravitationally self‐consistent model of glacial and sediment isostatic adjustment (SIA) along with a realistic sediment load reconstruction in this region for the first time to determine isostatic contributions to relative sea level (RSL) and land motion. We determine optimal model parameters (Earth rheology and ice history) using a new high‐quality compaction‐free sea level indicator database. Using the optimal model parameters, we show that SIA can lower predicted RSL in the MD area by several meters over the Holocene and so should be taken into account when modeling these data. We compare modeled contemporary rates of vertical land motion with those inferred using GPS. This comparison indicates that isostatic processes can explain the majority of the observed vertical land motion north of latitude 30.7°N, where subsidence rates average about 1 mm/yr; however, subsidence south of this latitude shows large data‐model discrepancies of greater than 3 mm/yr, indicating the importance of nonisostatic processes. This discrepancy extends to contemporary RSL change, where we find that the SIA contribution in the Delta is on the order of 10−1 mm/yr. We provide estimates of the isostatic contributions to 20th and 21st century sea level rates at Gulf Coast Permanent Service for Mean Sea Level tide gauge locations as well as vertical and horizontal land motion at GPS station locations near the MD.
Quasi‐3‐D Seismic Reflection Imaging and Wide‐Angle Velocity Structure of Nearly Amagmatic Oceanic Lithosphere at the Ultraslow‐Spreading Southwest Indian Ridge

Published: November 2017

AbstractWe present results from 3‐D processing of 2‐D seismic data shot along 100 m spaced profiles in a 1.8 km wide by 24 km long box during the SISMOSMOOTH 2014 cruise. The study is aimed at understanding the oceanic crust formed at an end‐member mid‐ocean ridge environment of nearly zero melt supply. Three distinct packages of reflectors are imaged: (1) south facing reflectors, which we propose correspond to the damage zone induced by the active axial detachment fault: reflectors in the damage zone have dips up to 60° and are visible down to 5 km below the seafloor; (2) series of north dipping reflectors in the hanging wall of the detachment fault: these reflectors may correspond to damage zone inherited from a previous, north dipping detachment fault, or small offset recent faults, conjugate from the active detachment fault, that served as conduits for isolated magmatic dykes; and (3) discontinuous but coherent flat‐lying reflectors at shallow depths (<1.5 km below the seafloor), and at depths between 4 and 5 km below the seafloor. Comparing these deeper flat‐lying reflectors with the wide‐angle velocity model obtained from ocean‐bottom seismometers data next to the 3‐D box shows that they correspond to parts of the model with P wave velocity of 6.5–8 km/s, suggesting that they occur in the transition between lower crust and upper mantle. The 4–5 km layer with crustal P wave velocities is interpreted as primarily due to serpentinization and fracturation of the exhumed mantle‐derived peridotites in the footwall of active and past detachment faults.
A Theoretical Model of Drumlin Formation Based on Observations at Múlajökull, Iceland

Published: November 2017

AbstractThe drumlin field at the surge‐type glacier, Múlajökull, provides an unusual opportunity to build a model of drumlin formation based on field observations in a modern drumlin‐forming environment. These observations indicate that surges deposit till layers that drape the glacier forefield, conform to drumlin surfaces, and are deposited in shear. Observations also indicate that erosion helps create drumlin relief, effective stresses in subglacial till are highest between drumlins, and during quiescent flow, crevasses on the glacier surface overlie drumlins while subglacial channels occupy intervening swales. In the model, we consider gentle undulations on the bed bounded by subglacial channels at low water pressure. During quiescent flow, slip of temperate ice across these undulations and basal water flow toward bounding channels create an effective stress distribution that maximizes till entrainment in ice on the heads and flanks of drumlins. Crevasses amplify this effect but are not necessary for it. During surges, effective stresses are uniformly low, and the bed shears pervasively. Vigorous basal melting during surges releases debris from ice and deposits it on the bed, with deposition augmented by transport in the deforming bed. As surge cycles progress, drumlins migrate downglacier and grow at increasing rates, due to positive feedbacks that depend on drumlin height. Drumlin growth can be accompanied by either net aggradation or erosion of the bed, and drumlin heights and stratigraphy generally correspond with observations. This model highlights that drumlin growth can reflect instabilities other than those of bed shear instability models, which require heuristic till transport assumptions.
