Published: October 2017

Abstract. Natural iron fertilization downstream of Southern Ocean island plateaus support large phytoplankton blooms and promote carbon export from the mixed layer. In addition to sequestering atmospheric CO2, the biological carbon pump also supplies organic matter (OM) to deep-ocean ecosystems. Although the total flux of OM arriving at the seafloor sets the energy input to the system, the chemical nature of OM is also of significance. However, a quantitative framework linking ecological flux vectors to OM composition is currently lacking. In the present study we report the lipid composition of export fluxes collected by five-moored sediment traps deployed in contrasting productivity regimes of Southern Ocean island systems (Kerguelen, Crozet and South Georgia) and compile them with quantitative data on diatom and fecal pellet fluxes. At the three naturally iron fertilized sites, the relative contribution of labile lipids (mono- and polyunsaturated fatty acids, unsaturated fatty alcohols) is 2–4 times higher than at low productivity sites. There is a strong attenuation of labile components as a function of depth, irrespective of productivity. The three island systems also display regional characteristics in lipid export. The diversity of sterols is greater in the relatively warm waters of the Polar Frontal Zone when compared to the Antarctic zone, reflecting the transition from mixed phytoplankton communities to principally diatom-derived OM. An enrichment of zooplankton dietary sterols, such as C27Δ5, at South Georgia is consistent with high zooplankton and krill biomass in the region and the importance of fecal pellets to POC flux. There is a strong association of diatom resting spore fluxes that dominate productive flux regimes with energy rich unsaturated fatty acids. At the Kerguelen Plateau we provide a statistical framework to link seasonal variation in ecological flux vectors and lipid composition over a complete annual cycle. Our analyses demonstrate that ecological processes in the upper ocean, e.g. resting spore formation and grazing, not only impact the magnitude and stoichiometry of the Southern Ocean biological pump, but also regulate the composition of exported OM and the nature of pelagic-benthic coupling.

Published: October 2017

Abstract. The Tatuoca magnetic observatory (IAGA code: TTB) is located on a small island in the Amazonian delta in the state of Pará, Brazil. Its location close to the geomagnetic equator and within the South Atlantic Anomaly offers a high scientific return of the observatory's data. A joint effort by the National Observatory of Brazil (ON) and the GFZ German Research Centre for Geosciences (GFZ) was undertaken, starting from 2015 in order to modernise the observatory with the goal of joining the INTERMAGNET network and to provide real-time data access. In this paper, we will describe the history of the observatory, recent improvements, and plans for the near future. In addition, we will give some comments on absolute observations of the geomagnetic field near the geomagnetic equator.
GPU-accelerated atmospheric chemical kinetics in the ECHAM/MESSy (EMAC) Earth system model (version 2.52)
Authors: Alvanos Michail , Christoudias Theodoros
Published: October 2017

Abstract. This paper presents an application of GPU accelerators in Earth system modeling. We focus on atmospheric chemical kinetics, one of the most computationally intensive tasks in climate–chemistry model simulations. We developed a software package that automatically generates CUDA kernels to numerically integrate atmospheric chemical kinetics in the global climate model ECHAM/MESSy Atmospheric Chemistry (EMAC), used to study climate change and air quality scenarios. A source-to-source compiler outputs a CUDA-compatible kernel by parsing the FORTRAN code generated by the Kinetic PreProcessor (KPP) general analysis tool. All Rosenbrock methods that are available in the KPP numerical library are supported.Performance evaluation, using Fermi and Pascal CUDA-enabled GPU accelerators, shows achieved speed-ups of 4. 5 ×  and 20. 4 × , respectively, of the kernel execution time. A node-to-node real-world production performance comparison shows a 1. 75 ×  speed-up over the non-accelerated application using the KPP three-stage Rosenbrock solver. We provide a detailed description of the code optimizations used to improve the performance including memory optimizations, control code simplification, and reduction of idle time. The accuracy and correctness of the accelerated implementation are evaluated by comparing to the CPU-only code of the application. The median relative difference is found to be less than 0.000000001 % when comparing the output of the accelerated kernel the CPU-only code.The approach followed, including the computational workload division, and the developed GPU solver code can potentially be used as the basis for hardware acceleration of numerous geoscientific models that rely on KPP for atmospheric chemical kinetics applications.
Atmospheric inverse modeling via sparse reconstruction
Authors: Hase Nils , Miller Scot M. , Maaß Peter , Notholt Justus , Palm Mathias , Warneke Thorsten
Published: October 2017

Abstract. Many applications in atmospheric science involve ill-posed inverse problems. A crucial component of many inverse problems is the proper formulation of a priori knowledge about the unknown parameters. In most cases, this knowledge is expressed as a Gaussian prior. This formulation often performs well at capturing smoothed, large-scale processes but is often ill equipped to capture localized structures like large point sources or localized hot spots. Over the last decade, scientists from a diverse array of applied mathematics and engineering fields have developed sparse reconstruction techniques to identify localized structures. In this study, we present a new regularization approach for ill-posed inverse problems in atmospheric science. It is based on Tikhonov regularization with sparsity constraint and allows bounds on the parameters. We enforce sparsity using a dictionary representation system. We analyze its performance in an atmospheric inverse modeling scenario by estimating anthropogenic US methane (CH4) emissions from simulated atmospheric measurements. Different measures indicate that our sparse reconstruction approach is better able to capture large point sources or localized hot spots than other methods commonly used in atmospheric inversions. It captures the overall signal equally well but adds details on the grid scale. This feature can be of value for any inverse problem with point or spatially discrete sources. We show an example for source estimation of synthetic methane emissions from the Barnett shale formation.

Abstract. The objectives of the study are to explore the changes in water balance components (WBC) by co-utilizing discrete wavelet transformation (DWT) and different forms of Mann–Kendal (MK) test; and to develop wavelet autoregressive moving average (ARIMA) models for forecasting the WBC. Trend test results reveal that the most of the trends (about 73 %) identified in potential evapotranspiration (PET) show decreasing tendency during the hydrological year 1981–82 to 2012–13 in the western part of Bangladesh, however most of the changes (about 82 %) are insignificant at 5 % significant level. Actual evapotranspiration (AET), annual deficit and annual surplus also show the almost similar tendency. Rainfall and temperature show increasing trends, but WBC show inverse of this tendency and suggesting that traditional concept of changes in PET associated with changes in temperature cannot explain the changes in WBC. Moreover, it is found that generally 8-years (D3) to 16-years (D4) periodic components are the effective components and are responsible for trends found in original data of WBC in western part of Bangladesh. Wavelet denoising of WBC time series has been done to improve the performance of models as actual data affected by noise and show unsatisfactory performances. The quality of denoised data has been ensured by relevant statistical analysis. Performance of wavelet ARIMA models have been assessed by Nash–Sutcliffe Efficiency (NSE) coefficient and coefficient of determination (R2). The obtained results indicate that performances of wavelet ARIMA models of WBC are acceptable to very good and clearly demonstrate the advantages of denoising over actual data. The models validation results reveal that the forecasted values are very close to actual values with acceptable mean percentage error and residuals also follow normally distribution. Performances and validation results indicate that models can be used for short term forecasting of WBC. Further studies on different combinations of wavelet analysis would be facilitated to develop better models for WBC in context of climate change and findings of study can be used to improve water resources management in highly irrigated western part of Bangladesh.
Topography significantly influencing low flows in snow-dominated watersheds

Published: October 2017

Abstract. Watershed topography plays an important role in determining the spatial heterogeneity of ecological, geomorphological, and hydrological processes. Few studies have quantified the role of topography on various flow variables. In this study, 28 watersheds with snow-dominated hydrological regimes were selected with daily flow records from 1989 to 1996. The watersheds are located in the Southern Interior of British Columbia, Canada and range in size from 2.6 to 1,780 km2. For each watershed, 22 topographic indices (TIs) were derived, including those commonly used in hydrology and other environmental fields. Flow variables include annual mean flow (Qmean), Q10%, Q25%, Q50%, Q75%, Q90%, and annual minimum flow (Qmin), where Qx% is defined as flows that at the percentage (x) occurred in any given year. Factor analysis (FA) was first adopted to exclude some redundant or repetitive TIs. Then, stepwise regression models were employed to quantify the relative contributions of TIs to each flow variable in each year. Our results show that topography plays a more important role in low flows than high flows. However, the effects of TIs on flow variables are not consistent. Our analysis also determines five significant TIs including perimeter, surface area, openness, terrain characterization index, and slope length factor, which can be used to compare watersheds when low flow assessments are conducted, especially in snow-dominated regions.
Impacts of Changing Hydrology on Ravine Growth: Experimental Results
Authors: Day Stephanie S. , Gran Karen B. , Paola Chris
Published: October 2017

Abstract. Ravines grow through head cut propagation in response to overland flow coupled with incision and widening in the channel bottom leading to hillslope failures. Altered hydrology can impact the rate at which ravines grow by changing head-cut propagation, channel incision, and channel widening rates. Using a set of small physical experiments, we tested how changing overland flow rates and flow volumes alter the total volume of erosion and resulting ravine morphology. Ravines were modeled as both detachment-limited and transport-limited systems, using two different substrates with varying cohesion. In both cases, the erosion rate varied linearly with water discharge, such that the volume of sediment eroded was a function not of flow rate, but of total water volume. This implies that efforts to reduce peak flow rates alone without addressing flow volumes entering ravine systems may not reduce erosion. The documented response in these experiments is not typical when compared to larger pre-existing channels where higher flow rates result in greater erosion through non-linear relationships between water discharge and sediment discharge. Ravines do not respond like pre-existing channels because channel slope remains a free parameter and can adjust relatively quickly in response to changing flows.
VEGETATION ANALYSIS AND LAND USE LAND COVER CLASSIFICATION OF FOREST IN UTTARA KANNADA DISTRICT INDIA USING REMOTE SENSIGN AND GIS TECHNIQUES
Authors: Koppad A. G. , Janagoudar B. S.
Published: October 2017

Abstract. The study was conducted in Uttara Kannada districts during the year 2012–2014. The study area lies between 13.92° N to 15.52° N latitude and 74.08° E to 75.09° E longitude with an area of 10,215 km2. The Indian satellite IRS P6 LISS-III imageries were used to classify the land use land cover classes with ground truth data collected with GPS through supervised classification in ERDAS software. The land use and land cover classes identified were dense forest, horticulture plantation, sparse forest, forest plantation, open land and agriculture land. The dense forest covered an area of 63.32 % (6468.70 sq km) followed by agriculture 12.88 % (1315.31 sq. km), sparse forest 10.59 % (1081.37 sq. km), open land 6.09 % (622.37 sq. km), horticulture plantation and least was forest plantation (1.07 %). Settlement, stony land and water body together cover about 4.26 percent of the area. The study indicated that the aspect and altitude influenced the forest types and vegetation pattern. The NDVI map was prepared which indicated that healthy vegetation is represented by high NDVI values between 0.1 and 1. The non- vegetated features such as water bodies, settlement, and stony land indicated less than 0.1 values. The decrease in forest area in some places was due to anthropogenic activities. The thematic map of land use land cover classes was prepared using Arc GIS Software.
TOWARDS THE IMPLEMENTATION OF SEMI-DYNAMIC DATUM FOR MALAYSIA

Published: October 2017

Abstract. A semi-dynamic datum provides positions with respect to time while taking into account the secular and non-secular deformations, making it the best approach to adapt with the dynamic processes of the earth. Malaysia, as yet, employs a static datum, i.e., GDM2000, at epoch 2000; though Malaysia has evidently been affected by seismic activity for the past decade. Therefore, this paper seeks to propose a design for implementing a semi-dynamic datum for Malaysia. Methodologically, GPS time series analyses are carried out to investigate the seismic activity of Malaysia, which essentially contributes to the proposed design of the semi-dynamic datum for Malaysia. The implications of implementing a semi-dynamic datum for Malaysia are discussed as well. The results indicate that Malaysia undergoes a complex deformation; whereby the earthquakes – primarily the 2004 Sumatra-Andaman, 2005 Nias and 2012 Northern Sumatra earthquakes – have affected the underlying secular velocities of Malaysia. Consequently, from this information, the proposed design, particularly the secular and non-secular deformation models, is described in detail. The proposed semi-dynamic datum comprises a transformation, temporal, and spatial module, and utilizes a bilinear interpolation method. Overall, this paper aims to contribute to the feasibility of a semi-dynamic datum approach for Malaysia.

Published: October 2017

Abstract. Solar energy modelling is increasingly popular, important, and economic significant in solving energy crisis for big cities. It is a clean and renewable resource of energy that can be utilized to accommodate individual or group of buildings electrical power as well as for indoor heating. Implementing photovoltaic system (PV) in urban areas is one of the best options to solve power crisis over expansion of urban and the growth of population. However, as the spaces for solar panel installation in cities are getting limited nowadays, the available strategic options are only at the rooftop and façade of the building. Thus, accurate information and selecting building with the highest potential solar energy amount collected is essential in energy planning, environmental conservation, and sustainable development of the city. Estimating the solar energy/radiation from rooftop and facade are indeed having a limitation - the shadows from other neighbouring buildings. The implementation of this solar estimation project for Istanbul uses CityGML LoD2-LoD3. The model and analyses were carried out using Unity 3D Game engine with development of several customized tools and functionalities. The results show the estimation of potential solar energy received for the whole area per day, week, month and year thus decision for installing the solar panel could be made. We strongly believe the Unity game engine platform could be utilized for near future 3D mapping visualization purposes.

Abstract. Studies have shown that mangrove forests in the Philippines have been drastically reduced due to conversion to fishponds, salt ponds, reclamation, as well as other forms of industrial development and as of 2011, Iloilo’s 95 % mangrove forest was converted to fishponds. In this research, six (6) Landsat images acquired on the years 1973, 1976, 2000, 2006, 2010, and 2016, were classified using Support Vector Machine (SVM) Classification to determine land cover changes, particularly the area change of mangrove and aquaculture from 1976 to 2016. The results of the classification were used as layers for the generation of 3D visualization models using four (4) platforms namely Google Earth, ArcScene, Virtual Terrain Project, and Terragen. A perception survey was conducted among respondents with different levels of expertise in spatial analysis, 3D visualization, as well as in forestry, fisheries, and aquatic resources to assess the usability, effectiveness, and potential of the various platforms used. Change detection showed that largest negative change for mangrove areas happened from 1976 to 2000, with the mangrove area decreasing from 545.374 hectares to 286.935 hectares. Highest increase in fishpond area occurred from 1973 to 1976 rising from 2,930.67 hectares to 3,441.51 hectares. Results of the perception survey showed that ArcScene is preferred for spatial analysis while respondents favored Terragen for 3D visualization and for forestry, fishery and aquatic resources applications.

Published: October 2017

Abstract. Developing and implementing a quick response post-storm survey protocol has the potential to improve impact assessments of coastal storms. Pre- and post-event surveys are essential to properly quantify the storm impacts on the coast. In this study, a combination of traditional RTK GPS and Unmanned Aerial Vehicle drone platform was utilized as part of a coordinated storm response workflow. The comprehensive approach employed in this pilot case study was conducted on the Emilia-Romagna coast (Italy), in the immediate aftermath of an extreme storm event that impacted the shoreline on the 5th–6th February 2015 called the Saint Agatha Storm. The activities were supported by timing information on the approaching storm provided by the regional early warning system. We collected aerial photos from a commercial off-the-shelf drone immediately after the Saint Agatha Storm and generated both orthomosaic and digital elevation models utilizing structure-from-motion photogrammetry techniques. The drone- based survey approach allowed us to quickly survey an area of 0.25 km2 within a 10-minute flight resulting in a ground sampling distance of 2.5 cm/pixel. Flooding and erosion impacts are analyzed and presented for the target study area. Limitations and possible applications for coastal management of the quick response post-storm surveying protocol are highlighted.
Estimation of oceanic sub-surface mixing under a severe cyclonic storm using a coupled atmosphere-ocean-wave model
Authors: Prakash Kumar Ravi , Nigam Tanuja , Pant Vimlesh
Published: October 2017

Abstract. A coupled atmosphere-ocean-wave model used to examine mixing in the upper oceanic layers under the influence of a very severe cyclonic storm Phailin over the Bay of Bengal (BoB) during 10–14 October 2013. Model simulations highlight prominent role of cyclone induced near-inertial oscillations in sub-surface mixing up to the thermocline depth. The inertial mixing introduced by the cyclone played central role in deepening of thermocline and mixed layer depth by 40 m and 15 m, respectively. A detailed analysis of inertial oscillation kinetic energy generation, propagation, and dissipation was carried out at a location in northwestern BoB. The peak magnitude of kinetic energy in baroclinic and barotropic currents found to be 1.2 m2 s−2 and 0.3 × 10−2 m2 s−2, respectively. The power spectrum analysis suggested a dominant frequency operative in sub-surface mixing was associated with near-inertial oscillations. The peak strength of 0.84 m2 s−1 in zonal baroclinic current found at 14 m depth. The baroclinic kinetic energy remain higher (> 0.03 m2 s−2) during 11–12 October and decreased rapidly thereafter. The wave-number rotary spectra identified the downward propagation, from surface up to the thermocline, of energy generated by inertial oscillations. A quantitative analysis of shear generated by the near-inertial baroclinic current showed higher shear generation at 40–80 m depth during peak surface winds. Analysis highlights that greater mixing within the mixed layer take place where the eddy kinetic diffusivity was high (> 6 × 10−11 m2 s−1). The turbulent kinetic energy dissipation rate increased from 4 × 10−14 to 2.5 × 10−13 W kg−1 on approaching the thermocline that dampened mixing process further downward into the thermocline layer.
Behavioral genetics and thumb sucking in adolescents
Authors: Hatala Jessica
Published: October 2017

Thumb sucking is a common habit developed by children and begins as early as in utero. However, it becomes problematic when a child continues to suck their thumb past the age of 4 years, when their secondary dentition is developing and preparing to erupt. Prolonged thumb sucking into adolescence can have deleterious effects on dental and skeletal structures based on the duration and how frequent the child engages in this nonnutritive sucking habit.  Thumb sucking can lead to various types of effects such as increased overjet, anterior open bite, posterior cross bite, maxillary arch constriction, high palatal vault, and Class II malocclusion. This paper presents a case study, which focuses on chronic thumb sucking in a family, the dental and skeletal changes that the family members experienced, and whether or not this prolonged behavior can be genetically influenced. Based on this case study and the field of behavioral genetics it is possible that there can be a genetic component to the duration of thumb sucking into adolescence.
Familial inheritance of TMD: a case report
Authors: Genello Maria
Published: October 2017

The TMJ is a joint that can perform both hinge and sliding motions and whose proper functioning depends on the actions of the joint and joint capsule, the muscles of mastication, and the condition and action of the mandibular condyle. If any of these components deviate from their normal structure or function, then TMD can result. There have been many reported contributing factors to TMD development, many of which include environmental influences such as bruxism, trauma, and other oral habits. However, a genetic component can also play a role. This paper reports a case of TMD occurring within three consecutive generations of a family and explores the possibility of this disorder exhibiting familial inheritance. Members of the family affected all displayed manifestations of joint laxity in other areas of the body, migraines, pain, and had smaller craniofacial dimensions with a narrower mandible. These factors were found to have a genetic influence and these genes can also be tied to TMD, thus supporting the argument that the cases of TMD seen in this family are in fact due to inheritance. If TMD can be shown to have a genetic component and be inherited, then dental practitioners would be able to identify high risk patients and help to modify environmental factors early on in order to help prevent the onset of TMD in those individuals.
Class III malocclusion: an argument for early orthodontic treatment
Authors: Moe Eric
Published: October 2017

Class III malocclusion is a complex multifactorial condition with many genetic and environmental influences. Most often the condition is inherited in a Mendelian autosomal dominant pattern. Early referral and treatment can lead to better outcomes in orthodontic therapy. The subject presented for an early orthodontic referral at age 5.5 and showed signs of future Class III malocclusion. A rapid maxillary expander was given as interventional treatment for one year. At age 11.5 the subject was treated with braces for 2 years. The outcome was a normal Class I occlusion. The subject’s mother had Class III malocclusion but was not evaluated early and was only able to establish an edge-to-edge Class III malocclusion as the best treatment outcome without orthognathic surgery. The subject’s grandmother was also Class III, establishing an autosomal dominance pattern of inheritance in the family. This case demonstrates the importance of the general dentist educating families about malocclusion and making orthodontic referrals as early as possible so the best treatment outcomes can be reached through orthodontic therapy.

RESUMO: O presente trabalho tem como objetivo comparar a capacidade de carga de fundações rasas, tipo sapata, usando os valores de resistência à penetração dinâmica do ensaio PANDA 2 em solo tropical compactado, em substituição aos parâmetros obtidos pelos ensaios CPT e SPT, que implementam os métodos de dimensionamento tradicionais, bem como de fundações profundas, tipo estaca. Além disso, o trabalho abrange a análise do recalque em cada uma das situações propostas. A comparação foi feita a partir do cálculo da capacidade de carga de sapata e de estaca de dimensões predefinidas por meio de métodos teóricos e semi-empíricos. Os resultados para uso do PANDA 2 foram satisfatórios, apresentando pouca variabilidade quando comparado ao uso do SPT e CPT para dimensionamento de fundações no solo estudado. Quanto aos recalques, como esperado, o recalque previsto para a estaca foi relativamente menor que o recalque para a sapata. A principal contribuição deste trabalho foi a aplicação de nova tecnologia disponível para investigação geotécnica de campo, o ensaio Panda 2, em métodos de cálculos de previsão de capacidade de carga e de recalque de fundações.ABSTRACT: This study aims to compare the load capacity of shallow and deep foundations, spread footing and piles, using dynamic penetration resistance values of PANDA 2 test in tropical compacted soil, replacing the parameters obtained by CPT and SPT that implement the traditional methods of capacity of design load. Furthermore, this research includes also the settlements analysis in each of the situations proposed. The comparison of the load capacity of footing and pile with predefined dimensions was made through theoretical and semi-empirical methods. The PANDA 2 results use were satisfactory, with little variability when compared to SPT and CPT use for foundations design in the studied soil. With regard to settlements, as expected, the settlement for pile was relatively lower than the settlements on footing. The main contribution of this paper was the practical application of Panda 2 results use, through methods of estimate foundations load capacity and settlements.

Published: October 2017

RESUMO: Na inexistência dos projetos executivos é possível determinar a armadura da estrutura e o seu respectivo cobrimento a partir de aparelhos denominados pacômetros. O presente trabalho tem como objetivo analisar as leituras de equipamentos de dois modelos, o Profometer 5+ e o Wallscanner D-Tect 150, utilizados na detecção das armaduras e cobrimento de um dos pilares do viaduto em Curitiba. A metodologia desenvolvida foi dividida em três etapas, a primeira, para calibração dos equipamentos, realizada em pilares pré-moldados de concreto armado. Na segunda fase, foram executadas leituras em um pilar de um edifício comercial e finalmente, na terceira etapa foram realizadas medições em um pilar com armação desconhecida localizado no viaduto. As leituras realizadas mostraram a eficiência dos equipamentos na localização das armaduras, porém, apresentaram pouca precisão na determinação dos diâmetros das barras. Não foram detectadas armaduras localizadas em camadas mais profundas. Os dois aparelhos permitiram a estimativa do cobrimento das barras detectadas, contudo, a leitura foi bastante afetada em zonas de alta concentração de armadura. Os resultados obtidos, aliados à leveza e facilidade de uso dos equipamentos, permitiram concluir que é recomendável a utilização de pacômetros em inspeções preliminares de pilares de estruturas de concreto armado.ABSTRACT: In the absence of the executive projects it is possible to determine the armature of the structure and its respective covering from devices called pacemakers. The present work has the objective of analyzing the equipment readings of two models, Profometer 5+ and Wallscanner D-Tect 150, used in the detection of the reinforcement and covering of one of the columns of the bridge in Curitiba. The methodology developed was divided into three stages, the first one, for equipment calibration, performed on precast concrete columns. In the second phase, readings were performed on a column of a commercial building and finally, in the third stage measurements were made on a column with unknown frame located on the viaduct. The readings showed the efficiency of the equipment in the location of the reinforcement, but presented little precision in the determination of the bar diameters. No reinforcement was found located in deeper layers. The two devices allowed the estimation of the covering of the detected bars, however, the reading was very affected in zones of high concentration of reinforcement. The results obtained, combined with the lightness and ease of use of the equipment, allowed us to conclude that the use of pacometers in preliminary inspections of pillars of reinforced concrete structures is recommended.

Published: October 2017

O objetivo do estudo foi analisar a atuação dos profissionais de Educação Física (PEF) nos Centros de Atenção Psicossocial (CAPS) dos municípios que compõe a 10ª Coordenadoria Regional de Saúde – RS. A coleta de dados se deu por meio de um questionário composto de perguntas abertas e fechadas. A amostra foi composta por 6 PEF. Os resultados indicam que os PEF não receberam em sua graduação nenhuma formação relacionada a saúde mental. A atuação dos PEF envolve práticas variadas como atividades esportivas, recreativas, entre outras, ministradas nas dependências dos CAPS e em espaços públicos. Frente ao que é exposto, sugere-se mudanças, iniciando pela grade curricular dos cursos de graduação e no investimento em capacitações, de modo, a ampliar o conhecimento dos profissionais.

Authors: Silva Darlan Ferreira , Oliveira Rezende Maria Olimpia
Published: October 2017

An alternative method for microwave-assisted extraction of organic sulphur in sewage sludge samples was optimized based on response surface methodology. The extraction process was defined by a 23 factorial design. In the factorial design, the temperature, the extraction time and the volume of hydrochloric acid in the solvent mixture were evaluated. The samples were extracted with a mixture of nitric acid and hydrochloric acid. The data obtained for study were based on the concentration of sulphur in the sulfate form (S-SO42-) obtained spectrophotometrically in the sludge samples. The initial extraction parameters were adjusted so that spectrophotometric determination was feasible. According to the levels (minimum and maximum) defined for each parameter, the methodology showed that the best extraction conditions were achieved with an extraction temperature of 150 °C, using a longer extraction time (40 min). This study was carried out to evaluate the efficiency of microwave-assisted extraction in spectrophotometric determination of sulphur in sludge samples.
Strange Stage Fellows? Arthur Miller and Harold Pinter
Authors: Greenfield Thomas A. , Carlo Erin M.
Published: October 2017

The body of critical literature concerned with direct comparison between the drama of Arthur Miller and Harold Pinter divides into two contradictory threads. The older, larger thread sees the work of Miller and Pinter as stylistic and intellectual antonyms for one another, an argument grounded in Pinter's early identification with Esslin's The Theatre of the Absurd (1961) and Absurdism's rejection of the kind of dramatic realism and linguistic coherence associated with Miller's best-known works. More recently a small number of critics have introduced a counter thread of interpretations, exploring the means by which Miller and Pinter represent in selected plays similar political, historical, or sociological ideas. This essay takes inspiration from this later thread, presenting a comparison of similarities between Death of a Salesman's Willy Loman and The Homecoming's Max. The article specifically addresses Willy and Max's self-conferral of a bogus ancestral patriarchic authority over their respective households—an authority that is entirely at odds with the actual conditions of their lives.

Authors: Heros Aguilar Elizabeth , Gómez Pando Luz , Sosa Guillermo
Published: October 2017

Doce genotipos de arroz fueron estudiados en condiciones de campo, en condiciones inundadas y en ambientes de sequía moderada y severa. Se utilizó el diseño de parcelas divididas con dos repeticiones, ubicando en parcelas los tratamientos de manejo de riego (tres) y en sub-parcelas los genotipos (12), con una separación de diez metros para controlar la filtración lateral.La siembra directa se realizó en hileras, utilizando una densidad de 80 Kg ha-1. El rendimiento en grano se ajustó a 14 % de humedad. Para cada genotipo se determinó la tolerancia a sequía utilizando los siguientes índices de selección: Índice de Susceptibilidad al Estrés (ISE), Productividad Media Geométrica (PMG), Productividad Media (PM), Media Armónica (MA), Índice de Tolerancia al Estrés (ITE), Índice de Rendimiento (IR), Índice de Estabilidad de Rendimiento (IER) e Índice de Resistencia a Sequía (IRS).Se observaron diferencias significativas entre rendimientos en condiciones de inundación y estrés en los índices Productividad Media Geométrica (PMG), Media Armónica (MA) y Productividad Media (PM). Los coeficientes de correlación indican que estos índices podrían ser utilizados para la identificación de genotipos de arroz tolerantes a sequía. Los análisis de los gráficos tridimensionales indican que IR71706 es el genotipo más tolerante a sequía y puede sembrarse en condiciones de riego y aridez.Producción Agropecuaria y Desarrollo Sostenible, Vol. 2, 2014: 11-31
