The role of rainfall variability in reservoir storage management at Shiroro hydropower dam, Nigeria
Authors: Suleiman YM , Ifabiyi IP 
Published: July 2014

Reservoir operation and management is usually patterned after the background of long standing water resources management experience. Reservoir management for optimum power production at any hydropower station requires constant assessment of the quantity of available water. The hydrographic responses of flow monitoring and statistical analysis of instrumental hydro-met records, especially rainfall and stream flow provide the necessary springboard for soundoperational decisions. Statistical analysis of hydrometeorological data (rainfall, inflow, reservoir storage and turbine release) at Shiroro dam was carried out with the aim of detecting spatio - temporal trends. Correlation and regression analysis were used to develop models for the variables. The correlation of between 0.120 and 0.774 revealed favourable relationships between the variables. This has invariably affected reservoir storage at the dam as excess water is released from the dam to sustain power generation over the years. It is recommended that dam operators optimize the release of water from Shiroro dam and ensure continuous monitoring of changes in hydrometeorological variables to provide early warning systems for effective performance of the dam and to protect downstream environment.

Infertility, as a social and cultural problem affecting individuals and families, makes People Living with Infertility (PLWI) to seek solution through different pathways, but with little or no information on patriarchal barrier(s) militating against counselling in the course of treatment. The study, therefore, investigated infertility treatments and counselling in the context of patriarchy among Ijebu, south western Nigeria. The study utilized Ecology Model as theoretical guide and cross-sectional survey design was adopted for data gathering. Two local government areas were purposively selected: Ijebu North and Ijebu-Ode LGAs. Infertile females were purposively selected in the churches and other care centres. Questionnaires were administered on snowball basis. Eight in-depth interviews (IDIs) were conducted for two medical doctors, two Traditional Birth Attendants (TBAs), two opinion leaders and two clergy. Quantitative data were analysed with simple percentage. Content analysis was used for qualitative data. Assisted reproductive technologies - ARTs were not acceptable. 62% agreed that government should intensify legislation, health education; legal and medical counselling centres that would provide level playing ground for PLWI. PLWI to have easy access to the treatments, social and financial costs should be de-emphasized and the need for counselling should be emphasized in case of ARTKey words: Patriarchy, Infertility, Health-seeking behaviour, Counselling, Gender inequality.

Authors: Raju Minu 
Published: July 2014

ABSTRACT

Background and objectives
This in vitro study compared and determined the temperature increase in the pulp chamber of permanent maxillary first premolar teeth placed in contact with different resins used for the fabrication of provisional resto- rations.

Materials and methods
Polymethyl methacrylate (DPI), poly- ethyl methacrylate (SNAP), polyvinylethyl methacrylate (TRIM), bis-acrylic composite (Protemp II) were compared with respect to their exothermic properties during polymerization. Eighty freshly extracted maxillary first premolars were prepared for complete coverage restoration were placed in an acrylic resin block. A thermal probe connected to a digital thermometer was placed into the pulp chamber. Specimens were submerged in a water bath to simulate intraoral conditions. The provisional materials were manipulated according to manufacturer's instructions. The resin mix was placed into template and was then positioned on the prepared tooth. The temperature was recorded during the polymerization at 30-second intervals until it was evident that the peak temperature had been reached.
After complete polymerization, the template was removed from the tooth and the provisional crown was retrieved. Data was analyzed with one-way ANOVA and Bonferroni multiple comparisons test.

Results
Mean temperature increase for the provisional crown fabrication ranged from 38.78°C, 37.79°C, 37.71°C and 35.88°C for polymethyl methacrylate, polyethyl methacrylate, polyvinyl- ethyl methacrylate and bis-acrylic composite respectively.
Polymethyl methacrylate, polyethyl methacrylate and bisacrylic composite were highly significant.

Interpretation and conclusion
All the materials used were in the safer limit. Hence, by comparing all the four material, Bis-acrylic composite showed least temperature rise in pulp chamber.

Published: July 2014

ABSTRACT
High intake of fluoride causes developmental disturbances of tooth enamel leading to dental fluorosis. It produces mottling of enamel and its occurance depends upon the quantity of fluoride ingested and the stage of tooth development. Esthetic management of mottled teeth is planned according to the severity of discoloration and the extent of surface aberrations. A combination of different techniques makes the teeth lighter in shade with a smoother surface. This case report describes the management of fluorosed teeth which is discolored and pitted on the surface by minimally invasive procedures.

Em um crescente processo de inclusão escolar, o ingresso de pessoas com deficiência intelectual tem representado um número significativo não somente no ambiente escolar como também no atendimento educacional especializado. A inclusão desses alunos tem despertado uma atenção especial assim como a necessidade de fazer ajustes ereflexões. Uma contribuição nesse sentido é a prática da consultoria colaborativa, que pode ser considerada como uma parceria entre professor de educação especial, ensino comum e outros profissionais. A efetivação dessa parceria pode trazer importantes contribuições para a família, para a escola epara a comunidade. Neste sentido, a consultoria colaborativa pode ser uma alternativa para a inclusão de pessoas com deficiência intelectual, não apenas no âmbito da intervenção mas também no âmbito da prevenção, da reflexão e da transformação do meio escolar.

Concordâncias/Discordâncias acerca do processo inclusivo no ensino superior: um estudo exploratório.
Authors: Marques Lígia Da Silva , Gomes Cláudia 
Published: July 2014

http://dx.doi.org/10.5902/1984686X8842 Com objetivo de caracterizar a concordância docente acerca da inclusão no ensino superior de alunos com deficiências, transtornos globais do desenvolvimento e superdotação; bem como a avaliação que os próprios docentes fazem quanto à preparação profissional e institucional necessária a este processo, foram participantes deste estudo 20 professores de uma universidade federal da região sul mineira, que responderam a um questionário sobre a temática investigada. Após analise quantitativa dos dados, obteve-se os seguintes resultados: os professores têm conhecimento da necessidade de se instaurar um cenário inclusivo eficaz na instituição e confirmam a necessidade de preparação física e de funcionários para fazê-lo; porém indicam não se sentirem capacitados para tanto. Em relação à concordância com a inclusão de pessoas com deficiências sensoriais, pôde-se evidenciar que os professores refletem concordância total ou parcial; já no caso de necessidades vinculadas aos distúrbios comportamentais, déficits intelectuais ou deficiências múltiplas, é indicada discordância. Isto parece denotar que quanto maior a necessidade de comprometimentos e ações profissionais diferenciadas, bem como adaptações curriculares e pedagógicas; menor a concordância com a inclusão, principalmente para professores que lecionam na área de Ciências Exatas. Como considerações finais, ressaltamos a necessidade de avançarmos para discussões e práticas educacionais que sustentem a atuação profissional inclusiva, ações estas consideradas pelos docentes participantes do estudo como de suas responsabilidades e competências profissionais e que são concepções alinhadas e propicias para a instauração e/ou fortalecimento de ações que garantam condições atitudinais, pedagógicas e institucionais que embasem a construção de uma universidade com o intuito de garantir acesso, permanência e desenvolvimento à todos os seus alunos.
(Des)continuidade nos estudos de alunos com deficiência na trajetória do Ensino Fundamental ao Médio: uma análise inicial dos microdados MEC/INEP

http://dx.doi.org/10.5902/1984686X9132 Este estudo visa colaborar com as discussões das políticas públicas de educação especial, principalmente, no que tange ao alunado com deficiência, matriculado no ensino médio. Para tanto, discorreu-se sobre as conquistas legais que denotam a garantia e obrigatoriedade dessa etapa de ensino na educação básica, bem como suas vicissitudes no contexto da inclusão educacional. Na sequência, a partir apreciação dos Microdados do Censo Escolar, que considera o número total de matrículas e, especificamente, do alunado com deficiência, apresentaram-se os cinco grupos que foram organizados para a análise de dados referentes aos anos: 2007, 2008 e 2010. Sendo que, optou-se por contabilizar as matrículas dos alunos com: cegueira, baixa visão, surdez, deficiência auditiva, surdocegueira, deficiência física, deficiência mental, síndrome de Down e deficiência múltipla (terminologia usada pelo MEC/ Inep). Concluiu-se que houve, marcadamente, maior queda nas matrículas de alunos com deficiência em relação ao total de matrículas efetivadas na educação básica, desvelando, o quanto o acesso e a permanência desse alunado no ensino médio, última etapa da educação básica, ainda são negligenciados e carecem de pesquisas, avaliação e acompanhamento. A descontinuidade de estudos desta parcela da população demonstra que ainda estamos distantes da garantia do direito à educação a todos e que o engajamento estatal é fundamental para que isso ocorra.

http://dx.doi.org/10.5902/1984686X9633 Este trabalho tem como objetivo apresentar os achados de uma investigação que buscou reconstruir a história de vida de Walkírio Ughini Bertoldo, considerado o primeiro cego brasileiro que concluiu a educação superior no país, no ano de 1957. Essa história será narrada enfatizando os obstáculos por ele enfrentados, ao longo da trajetória por essa etapa da sua escolarização, e analisando as estratégias por ele utilizadas para sua superação. O processo investigativo, que resultou na história de vida do sujeito, foi guiado pelos procedimentos relativos ao método biográfico. Os dados foram coletados por meio de entrevistas com três informantes que estiveram imersos na realidade de Bertoldo durante a realização de seu curso de graduação: dois colegas de faculdade, que depois passaram a ser, também, colegas de trabalho, e sua irmã. O corpus da investigação foi complementado com fontes documentais relativas à vida do sujeito. Os resultados evidenciaram que a trajetória de Bertoldo pela educação superior foi marcada por sua grande dedicação e empenho relativos a tal atividade; ainda, mostraram as resistências da instituição de ensino superior em aceitar o graduando cego e as estratégias utilizadas por ele para estudar, ainda que sem material adaptado.

Published: July 2014

AbstractA high‐resolution realistic numerical model of the Solomon Sea, which exhibits a high level of variability at mesoscales and submesoscales, is used to explore new avenues for data assimilation. Image data assimilation represents a powerful methodology to integrate information from high‐resolution observations such as satellite sea surface temperature or chlorophyll, or high‐resolution altimetric sea surface height that will be observed in the forthcoming SWOT mission. The present study investigates the feasibility and accuracy of the inversion of the dynamical submesoscale information contained in high‐resolution images of sea surface temperature (SST) or salinity (SSS) to improve the estimation of oceanic surface currents. The inversion method is tested in the context of twin experiments, with SST and SSS data provided by a model of the Solomon Sea. For that purpose, synthetic tracer images are built by binarizing the norm of the gradient of SST, SSS or spiciness. The binarized tracer images are compared to the dynamical image which is derived from the Finite‐Size Lyapunov Exponents. The adjustment of the dynamical image to the tracer image provides the optimal correction to be applied on the surface velocity field. The method is evaluated by comparing the result of the inversion to the reference model solution. The feasibility of the inversion of various images (SST, SSS, both SST and SSS or spiciness) is explored on two small areas of the Solomon Sea. We show that errors in the surface velocity field can be substantially reduced through the inversion of tracer images.
Normal faulting sequence in the Pumqu‐Xainza Rift constrained by InSAR and teleseismic body‐wave seismology

Published: July 2014

AbstractNormal faulting earthquakes play an important role in the deformation of continents, and pose significant seismic hazard, yet important questions remain about their mechanics. We use InSAR and body‐wave seismology to compute dislocation models and centroid moment solutions for four normal‐faulting earthquakes (Mw5.7–6.2) that occurred in the Pumqu‐Xainza Rift (PXR), southern Tibet, a region where low‐angle normal faulting has previously been inferred. We also use the fault locations and slip to investigate the correlation between earthquakes and surface topography, and to calculate stress interactions between the earthquakes. The InSAR and body‐wave models give consistent focal mechanisms except for the magnitude of the 1996 event, which may be overestimated due to postseismic deformation in the long‐interval interferograms. We calculate the static stress changes due to coseismic slip and find that the 1993 event was too distant to cause triggering of the later events, but that the 1998 event pair occurred in regions of increased Coulomb stress resulting from the 1996 event. All the fault planes found here dip at 40–60°, reinforcing the absence in observations for low‐angle normal faulting earthquakes (dip < 30°) whose focal planes can be determined unambiguously. The fault planes of the 1993 and 1996 events are not associated with any obvious surface geomorphology, suggesting that sometimes it is unreliable to resolve the focal plane ambiguity by geomorphology, even for Mw6.2 events. Furthermore, these events occurred outside the center of the rift, indicating that the active faulting is more distributed and over a length‐scale at least 25–50 km east‐west in extent, rather than confined to the 20 km width seen in the current mapped faulting and topography. These results suggest that seismic hazard in other extensional zones worldwide might also be more broadly distributed than suggested by geomorphology.
An analysis of aeolian dust in climate models
Authors: Evan Amato T. , Flamant Cyrille , Fiedler Stephanie , Doherty Owen 
Published: July 2014

AbstractAeolian dust is a key aspect of the climate system. Dust can modify the Earth's energy budget, provide long‐range transport of nutrients, and influence land surface processes via erosion. Consequently, effective modeling of the climate system, particularly at regional scales, requires a reasonably accurate representation of dust emission, transport, and deposition. Here we evaluate African dust in 23 state‐of‐the‐art global climate models used in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. We find that all models fail to reproduce basic aspects of dust emission and transport over the second half of the twentieth century. The models systematically underestimate dust emission, transport, and optical depth, and year‐to‐year changes in these properties bear little resemblance to observations. These findings cast doubt on the ability of these models to simulate the regional climate and the response of African dust to future climate change.

ABSTRACTElectrospinning of biodegradable poly(3‐hydroxybutyrate) (PHB)/magnetite and poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV)/magnetite composites in 2,2,2‐trifluoroethanol (TFE) and chloroform are investigated to develop nonwoven nanofibrous structure. Ultrafine PHB/magnetite fibers are obtained and the resulting fiber diameters are in the range of 690–710 nm and 8.0–8.4 µm for the polymer dissolved in TFE and chloroform. The surface of PHB composites fiber fabricated in chloroform contains porous structures, which are not observed for the sample of PHB composites fiber dissolved in TFE. The fiber diameters for PHBV5/magnetite composites are in the range of 500–540 nm and 2.3–2.5 µm, depending on the use of TFE and chloroform. The average diameters of PHBV5/magnetite composite fibers are smaller than those of PHB/magnetite composites fiber. All electrospun PHB/magnetite and composite fibers are superparamagnetic. The degradation behaviors of PHB/magnetite and PHBV5/magnetite composite fibers were investigated using Caldimonas manganoxidans. For the fabricated composite fibers, it is found that the degradation rate increased with the increasing loading of magnetite nanoparticles. © 2014 Wiley Periodicals, Inc. J. Appl. Polym.

The DOPA‐functionalized bioadhesive with properties of photocrosslinked and thermoresponsive

Published: July 2014

ABSTRACTThe unusual amino acid l‐3,4‐dihydroxyphenylalanine (DOPA), which was found in mussel adhesive protein, was recognized as crucial element for the adhesive of mussel. In this work, the synthesis of thermoresponsive and photocrosslinkable bioadhesive with ternary networks prepared by incorporating dopamine acrylamide (DAM) and N‐isopropylacrylamide (NIPAAm) into a crosslinked network based on poly(ethylene glycol)‐triacrylate (PEG‐TA) was reported. The effects of DAM and NIPAAm on polymerization kinetics, swelling kinetics, adhesion strength, thermomechanical properties, and cytotoxicity assays were systematically evaluated. The results showed that DAM could affect photopolymerization kinetics of terpolymer due to inhibitory effects of the catechol. The terpolymer has not only strong adhesion strength which was better than that of the commercial fibrin adhesives (0.05 MPa), but also the good humid‐resistant property. The thermoresponsive properties of the system were investigated by the measurement of swelling kinetics. The equilibrium swelling ratio of gels was obviously higher at 25°C than at 37°C. The thermomechanical properties of terpolymer indicated that the presence of the catechol moiety increased significantly the glass transition temperature (Tg) and crosslink density of ternary network. The results of cytotoxicity of gels indicated that terpolymer were biocompatible and less cytotoxicity towards the growth of mouse fibroblast cells (L929 cells). The obtained products could have the potential to serve as the bioadhesive in the future. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 41102.
