Abstract:
Abstract Polymer-based nanofibers are good candidates for medical textiles due to their excellent properties including high surface area, breathability and flexibility. Doping polymer nanofibers with different nanoparticles enhances their existing properties. In this study, electrospun polyamide 6,6 (PA6,6) composite nanofibers containing ZnO nanoparticles (<50 nm) in different amounts (1%, 3% and 5%) were first produced by electrospinning technique; then, these nanofibers were coated with sol-gel ZnO solution (0.5 m) via dip coating method at 1000, 3000 and 5000 μm/s speeds. The sol-gel coating process increased the breaking strength of nanofiber mats, while the incorporation of ZnO nanoparticles into the polymer nanofibers reduced. Compared to pure PA6,6 nanofiber mats, the ZnO sol-gel coated samples and doped nanofibers had lower reflectance values. In addition, the reflection values decreased as the additive and coating speed increased.

Abstract:
Purpose: of this research was examination Al2O3 thin film obtained with two different method, by sol-gel and ALD, and comparison the surface morphology and structure of deposited thin films. The films deposited on the monocrystalline silicon were tested for their suitability for use in silicon solar cells. Design/methodology/approach: Trimethylaluminum (TMA) was used as a precursor of Al2O3 which is reacted with water enabled the deposition of thin films by ALD method. By the sol-gel method the aluminium tri-sec butoxide (TBA) was used as a precursor to obtain Al2O3 thin films. The aluminium oxide solutions prepared by sol-gel method were deposited by spin coating technique. Examination of the structure and morphology of the surface of the Al2O3 thin films deposited by sol gel and ALD method were performed using atomic force microscope and transmission electron microscope. For the analysis of surface topography deposited thin films atomic force microscope XE-100 from Park Systems was used. Qualitative analysis of the chemical composition was carried out using an energy dispersion spectrometer (EDS). The detailed structural studies were conducted using a Titan 80-300 scanning-transmission electron microscope S/TEM from the FEI Company. Detailed research on the structure of the deposited Al2O3 thin films were performed. The HRTEM images and diffraction SAED were recorded. Findings: The small atoms clusters of a width less than 20 nm were documented. The thin film deposited by spin-coating technique on silicon substrate with 3000 rpm is characterized by RMS and Ra values of, respectively, 0.26 and 0.2 nm. RMS was defined as rough mean square parameter and Ra was defined as the arithmetic mean deviation of the profile from the mean line. An analysis of the frequency histograms of irregularities of the thin film obtained by the spin coating on a silicon substrate at 3000 rpm shows that a large part of them does not exceed 0.5 nm, and the single irregularities reach up to 2.2 nm. When comparing the AFM pictures with the thin films deposited by ALD technique and spin-coating it has been found that the thin films obtained on polished silicon substrates are similar in morphology. The EDS spectra shows the characteristic for oxygen (0.525 keV) and aluminum (1.486 keV) reflections derived from the thin film. In Al2O3 thin film obtained by ALD method the occurrence of α phase of aluminum oxide with a hexagonal structure was identified, just like in the case of thin film deposited by sol-gel. Practical implications: Known aluminium oxide properties and the possibility of obtaining a uniform thin layer show that it can be good material for different application. Precise description of the properties of Al2O3 is very important, since this material is one of the most frequently used in catalyst industry, in medicine, electronics and photovoltaics, as well as a protective layer. The Al2O3 thin film can act as passive and anti-reflective layer simultaneously in silicon solar cell. Using this thin film can simplify the technology of manufacturing silicon solar cells Originality/value: The paper presents researches of aluminium oxide thin films deposited by sol-gel and atomic layer deposition method on monocrystalline silicon.

Abstract:

Uppsatsen syftar till att undersöka hur värdegrundsbegreppen mångfald och tolerans implementerats i SO-ämnenas läroböcker. Uppsatsens didaktiska strävan är att skapa gott innehåll i undervisningen att motverka främlingsfientlighet och rasism.

De metoder som använts för att uppnå syftet och den didaktiska strävan är dels en kvantitativ mätning av värdegrundsbegreppens frekventa förekomst samt karaktäristiska framställning i Natur & Kulturs läromedel

Undersökningen av läroböckerna har visat att de normativa och värderande formuleringarna fått stå tillbaka till förmån för en deskriptiv framställning av skolans värdegrund samt att värdegrundsbegreppen har marginell omfattning i förhållande till läroböckernas totala text. Undersökningen visar också, att en didaktisk strävan att förbättra undervisningen kring värdegrundsfrågorna faller på lärarens medvetna val av studiematerial i undervisningen om etnicitet, rasism och främlingsfientlighet. Dessutom för att skapa en djupare förståelse krävs tvärvetenskapliga studier.

Abstract:
Le démarrage de l’irrigation basé sur un seuil de tension de l’eau dans le sol (SWTI) permet à la canneberge de se maintenir dans une zone de confort hydrique idéale à sa croissance. Ce seuil pourrait atteindre 6.5 voire 8.0 kPa selon différents auteurs. Afin de valider ces recommandations, une étude au champ était nécessaire. L’objectif principal de ce projet était de déterminer la valeur de SWT¬I permettant de maximiser la productivité de l’eau (WP) sans affecter le rendement. En 2011-2012, un dispositif expérimental aléatoire en blocs complets a été mis en place dans trois sites au Québec et dans un site au Wisconsin. Le sol des quatre sites était un sable fin. Ce dispositif a permis de tester des valeurs de SWTI variant de 5.5 à 10.0 kPa. Des traitements humides et des traitements secs ont été comparés à des traitements témoins. Les précipitations ont maintenu la tension de l’eau dans le sol inférieure à 8,5 kPa dans le site où ce traitement était prévu, l’empêchant ainsi d’être testé. La WP a été significativement supérieure de 15 à 79 % dans les traitements secs et significativement inférieure de 21 à 50 % dans les traitements humides. Le traitement sec ayant une valeur SWTI de 10.0 kPa a connu une baisse de rendement significative de 11 %. Aucun autre traitement n’a présenté de différence significative au niveau du rendement. Le sol peut fournir l’eau nécessaire aux besoins de la canneberge jusqu’à une tension de 8.0 kPa. Lorsque ce seuil est dépassé, le flux capillaire ne semble pas suffisant pour combler les besoins de la plante, ce qui entraîne une baisse de rendement. Basée sur les présents résultats, la valeur SWTI recommandée pour démarrer l’irrigation dans les sables fins est de 8.0 kPa afin de maximiser la productivité de l’eau sans affecter le rendement. En utilisant ce seuil, les producteurs de canneberge pourraient augmenter leur productivité en économisant de l’énergie et en réduisant les coûts de main d’œuvre associés à l’irrigation.
The onset of irrigation based on a soil water tension threshold (SWTI) allows cranberry plants to grow in a comfort zone. According to different authors, this threshold could be 6.5 kPa, or 8.0 kPa. A field study was required to confirm these recommendations. This study was conducted to determine the optimum SWTI value that would optimize water productivity (WP) without decreasing yield. A randomize complete block design has been set up during the 2011 and 2012 growing seasons in three sites in Québec and one site in Wisconsin. In all cases the soil was fine sand. Values of SWTI ranged from 5.5 to 10.0 kPa and dry and wet treatments were compared to control treatments. The treatment with a SWTI value of 8.5 kPa has never been irrigated because the rain kept soil water tension under this threshold. The WP was significantly greater from 15 to 79 % in dry treatments and significantly lower from 21 to 50 % in wet treatments. The dry treatment with a SWTI value of 10.0 kPa had a significant yield depletion of 11 %. It was the only treatment with a significant yield difference. Fine sands seem to have sufficient capillary flux to the cranberry uptake for a soil water tension up to 8.0 kPa. After this threshold, capillary flux seems to be too low to feed cranberry plants and results in yield depletion. Based on the current results, a SWTI value of 8.0 is recommended to maximise water productivity without affecting yield. With this threshold, cranberry growers could improve their productivity with energy and labor savings.

Este trabalho teve como objetivo avaliar os atributos químicos do solo, a produção, teor de proteína bruta e a concentração de macronutrientes em forrageiras de estação fria e quente sob adubação com vermicomposto bovino em um Luvissolo Háplico órtico típico no município de Bagé-RS. O experimento foi desenvolvido no Centro de Ciências Rurais da URCAMP, em duas épocas: estação fria (azevém) e estação quente (milheto). O experimento foi instalado em uma área de 136,5m2. O delineamento experimental foi de blocos ao acaso com cinco tratamentos e quatro repetições, sendo 4m2 o tamanho de cada parcela, e o espaçamento entre parcelas foi de 0,5m. Os tratamentos utilizados foram: (T1) sem vermicomposto e com calcário (testemunha); (T2) vermicomposto bovino (VB) 25% da recomendação total da Comissão de adubação e calagem do RS e SC (ROLAS) + calcário; (T3) VB 50% da recomendação total da ROLAS + calcário; (T4) VB 100% da recomendação total da ROLAS + calcário; (T5) VB 125% da recomendação total da ROLAS + calcário. As variáveis analisadas foram: fitomassa fresca e seca, proteína bruta e macronutrientes (N, P, K, Ca e Mg) da parte aérea das plantas e análise química do solo antes da instalação do experimento e após o ciclo de cada cultura. Os resultados foram: a adubação orgânica de forrageiras é uma excelente opção para as pequenas propriedades rurais; a utilização de 125% de vermicomposto bovino + calcário permite respostas significativas para as variáveis fitomassas fresca, seca e proteína bruta da parte aérea das culturas estudadas; os teores foliares dos nutrientes N, P, K na cultura do azevém respondem de forma crescente à aplicação da adubação orgânica. A concentração destes nutrientes diminui com o aumento da idade da planta em todos os tratamentos. Em relação ao solo, de uma maneira geral, é possível concluir que após a cultura do azevém há uma melhora na qualidade do mesmo, exceto para as variáveis: Mg, CTCpH7, Soma das bases, CTCefetiva e P nos tratamentos T1, T2 e T3. Após a cultura do milheto, há um acréscimo nos teores de P, Mg, CTCpH7 e diminuição dos teores de K; a cultura do azevém é mais responsiva à adubação orgânica do que cultura do milheto.
The aim of this study was to evaluate the yield, crude protein content and macronutrients concentration of winter and warm, chemical soil properties season forage crops under bovine manure fertilization in a Luvissolo Háplico órtico típico. The experiment was carried out at the Centro de Ciências Rurais da URCAMP, Bagé, RS, Brazil in two distinct seasons: ryegrass was cultivated during the winter and millet was cultivated during the summer. The experiment was conduced in a randomized block design, with five treatments and four replications. The size of each plot was 4m2 and the spacing between them was 0.5m, with a total area of 136.5m2. The treatments used were: (T1) no bovine manure vermicompost, only lime (control); (T2) bovine manure vermicompost (VB) at 25% of its total recommended rate by Manual de Adubação e Calagem do RS e SC (ROLAS) + lime; (T3) VB at 50% of Its total recommended rate by ROLAS + lime; (T4) VB at 100% of Its total recommended rate by ROLAS + lime; (T5) VB at 125% Its total recommended rate + lime. The variables analyzed were: green and dry biomass, crude protein content and macronutrients (N, P, K, Ca, Mg) of the aerial parts of the plants. Soil chemical analysis tests have also been performed before the experiment starts and after each crop cycle. The results were: the organic fertilization of forage crops is an excellent alternative for small farms; the use of bovine manure vermicompost at 125% of Its total recommended rate by ROLAS + lime increases considerably the variables: fresh and dry fitomass as well as the crude protein content of the aerial parts of the crops studied; foliar levels of N, P, K in the culture of ryegrass respond increasingly to the application of bovine manure vermicompost. The concentration of these nutrients decreased progressively with the aging of the plants in all treatments. In regards to the soil, it can be concluded that after the cultivation of ryegrass there was an improvement in quality thereof, except for the following variables: Mg, CTCpH7, Sum of Bases, effective CTC and P in T1, T2 and T3. After the cultivation of millet, It has been observed an increase in the levels of P, Mg, CTCpH7 and a decrease in the levels of K; The ryegrass crop is more responsive to organic fertilization than millet.

Esta tese interpreta experiências educativas na Extensão das Faculdades EST e as relações de Gênero, a partir da perspectiva da hermenêutica e da metodologia feministas. São apresentados os conceitos de indissociabilidade entre ensino, pesquisa e extensão, de acordo com os pressupostos do Fórum de Extensão. Traz os conceitos de opressão, de gênero e de patriarcado, advindos da teoria feminista em diálogo com os conceitos de in-exclusão social. A primeira parte da tese constitui o caminho metodológico da pesquisa, os contextos e os conceitos que se entrecruzam no estudo e mostra a complexidade que envolve a temática. A hermenêutica feminista é apresentada, a partir de Ivone Gebara e Wanda Deifelt, com destaque à metodologia feminista. É apresentada a noção de cotidiano e de experiência em diálogo com o conceito fazer-pensar, de Richard Senett. A segunda parte enfoca aspectos históricos da Extensão Universitária e o conceito de indissociabilidade como pano de fundo para o diálogo com o conceito de Gênero e Exclusão, trazendo a interface das perspectivas feministas para a trama dialógica. A análise a respeito da indissociabilidade e as relações de Gênero no contexto da EST são problematizadas pela hermenêutica feminista. O conceito de cativeiro, apresentado por Marcela Lagarde, desassossega os lugares e as práticas e mostra a ambiguidade das ações das mulheres na extensão. A extensão mostrou-se como zona de conforto e de reforço do patriarcado. Mas, também pode ser zona de rebeldia, de criatividade e de possibilidades para as mulheres. Concluí-se que há um contraponto entre teoria, metodologia e prática que, a partir de diferentes abordagens que dialogam e interagem, possibilita outras práticas extensionistas e baliza novas relações de gênero na instituição
This dissertation interprets educational experiences within the Extension program of the Faculdades EST and Gender relations, based on the perspective of feminist hermeneutics and methodology. The concepts of the indissociability of teaching,research and extension, are presented here according to the presuppositions of the Extension Forum. They bring with them the concepts of oppression, gender and patriarchy from the feminist theory in dialog with the concepts of social in-exclusion. The first part of the dissertation presents the methodological research path, the contexts and the concepts which cross each other in the study and show the complexity involved in the theme. Feminist hermeneutics is presented based on Ivone Gebara and Wanda Deifelt, highlighting feminist methodology. The notion of the quotidian and experience in dialog with the concept of to make think of Richard Senett is presented. The second part focuses on historical aspects of the University Extension Program and the concept of indissociability as the background for the dialog with the concept of Gender and Exclusion, bringing the interfacing of the feminist perspectives to the dialogical plot. The analysis with regard to indissociability and the relations of Gender in the context of EST is problematized by the feminist hermeneutics. The concept of captivity presented by Marcela Lagarde, disquiets the places and practices and shows the ambiguity of women?s actions in extension programs. The extension program presents itself as a zone of comfort and of reinforcement of the patriarchy. But it can also be a zone of rebelliousness, of creativity and of possibilities for the women. The conclusion is that there is a counterpoint between theory, methodology and practice which, based on different approaches which dialog and interact, makes possible other extension practices and sets apart new gender relations in the institution

The current ecological hypothesis states that the soil type (e.g., chemical and physical properties) determines which microbes occupy a particular soil and provides the foundation for soil provenance studies. As human profiles are used to determine a match between evidence from a crime scene and a suspect, a soil microbial profile can be used to determine a match between soil found on the suspect’s shoes or clothing to the soil at a crime scene. However, for a robust tool to be applied in forensic application, an understanding of the uncertainty associated with any comparisons and the parameters that can significantly influence variability in profiles needs to be determined. This study attempted to address some of the most obvious uncertainties of soil provenance applications such as spatial variability, temporal variability, and marker selection (i.e., taxa discrimination). Pattern analysis was used to validate the ecological theories driving the soil microbial biogeography. Elucidating soil microbial communities’ spatial and temporal variability is critical to improve our understanding of the factors regulating their structure and function. Microbial profiling and bioinformatics analyses of the soil community provided a rapid method for soil provenance that can be informative, easier to perform, and more cost effective than approaches using traditional physico-chemical data. This study also showed that stable profiles may allow comparison between evidence and a possible crime scene despite the time lapse (4 years) between sample collections, however, this is dependent on the analysis method, site, vegetation, and level of disturbance. Marker selection was also an important consideration for profiling. Even though Fungi look promising for single taxon soil discrimination, the additional markers can help discriminate between a wide variety of soil types. As in human identification, the more DNA markers queried the greater the discrimination power. Lastly, this study illustrated a novel method to query the iron relating genes and ability to design a novel marker that can easily be used to profile the functional diversity of a soil community to enhance soil classification. Overall this research demonstrated the potential and effectiveness of using microbial DNA from soil, not just for comparison, but also for intelligence gathering to pinpoint the geographic origin of the soil.

Abstract:
Devido às altas tensões envolvidas nos mecanismos de fadiga por contato, o uso de aços de alta dureza é uma exigência na fabricação de mancais de rolamento. Se a dureza de uma das partes em contato é baixa (sendo menor que 58 HRC), a ocorrência da descamação de camadas superficiais torna-se iminente no material menos duro. Estes defeitos superficiais podem, eventualmente, levar o componente a fraturar na direção radial se as tensões circunferenciais trativas forem relativamente elevadas. Os rolamentos que apresentam estes tipos de falhas são fabricados com o aço SAE 52100 temperado e revenido, com têmpera total. Recentemente tem sido sugerida a utilização do aço SAE 52100 processado por tratamento isotérmico para a obtenção de bainita inferior já que esta microestrutura apresenta boa tenacidade e resistência à fadiga associadas a uma alta dureza. Neste trabalho, foram realizados tratamentos térmicos utilizando o aço SAE 52100 a fim de obter microestruturas cujas matrizes fossem, predominantemente, martensita revenida ou bainita inferior. Para a condição martensítica, utilizou-se o tratamento térmico convencional de têmpera e revenido com três temperaturas de revenido para a obtenção de diferentes quantidades de austenita retida na matriz martensítica. Para a condição bainítica, utilizou-se o tratamento de austêmpera para a obtenção de bainita inferior com alto nível de dureza O comportamento mecânico do aço SAE 52100, tratado termicamente nas quatro condições, foi avaliado através de ensaio de tração e ensaio de impacto Charpy. O comportamento em fadiga, por sua vez, foi avaliado através de ensaios de propagação de trinca por fadiga realizados em corpos de prova tensão compacto. Para a determinação da influência da razão de carregamento (R=Kmin/Kmax) sobre o comportamento em fadiga este parâmetro foi variado entre 0,1 e 0,5. Foram realizadas análises fractográficas em todas as superfícies de fratura e de fadiga. Os resultados dos testes indicaram um melhor comportamento em fadiga para o aço SAE 52100 com microestrutura bainítica. No entanto para um R = 0,5, este material apresentou comportamento semelhante ao martensítico de mesmo nível de dureza na região limiar de fadiga. Observou-se o fenômeno de fechamento de trinca nos testes realizados com R de 0,1 e 0,3, sendo este efeito mais pronunciado para o menor valor de R.

Abstract:
Silica gels containing incorporated heteropolyacids (HPAs) were synthesized in acidic media by co-condensation of tetraethoxysilane (TEOS) with phosphotungstic or phosphomolybdic acids using sol-gel technique. Effect of the synthesis conditions on their structure and morphology was studied. Yields of modified materials were some lower as compared to non-modified silica gels. All materials were mesoporous but contained micropores in their structures. Presence of bands of Keggin’s structures in FT-IR spectra along with absence of XRD patterns of crystalline HPAs confirmed their fine incorporation into silica network. Particle sizes of modified materials were 800-1100 nm excepting for W-containing sample obtained with trimethylstearylammonium chloride. This unusual effect was attributed to stabilization of primary silica nanoparticles by interaction between surfactant and HPA. High ratio HPA/TEOS resulted in partial loss of porosity. Obtained results might be used for optimization of synthesis of effective catalysts and adsorbents containing HPAs in mesoporous structure.

The guarana cultivation has great social and economic importance in Maués City. Aimed at increasing crop yields, studies are needed on the plant population per unit area. This work aimed to evaluate the effects of different plant stands in the cultivation of guarana on aspects of vegetative growth, diseases, soil fertility and productivity, to improve the productive use of areas with the culture of guarana and reducing the impact of the implementation of the culture in new areas, providing an economic return for producers of guarana in Maués City, Amazonas State. We studied two clones BRS-Amazonas (CMU-300) and BRS-Maués (CMU-871) in booths of 625, 833, 1,111, 1,666, 2,500 and 5,000 plants per hectare. The experimental design for the analysis was completely randomized in factorial arrangement 2x6 and the number of replicates ranged from 3 to 10 according to the variables studied. The increase in the plant stands showed the economic viability for all indicators, with low risk of obtaining unfavorable results in the region analyzed when the used clones show high resistance to major diseases affecting the crop. There is need for continued evaluation to define the better stand of plants per unit area, which should be set at the end of at least five years of evaluation, after the stabilization of yield per plant.
O cultivo do guaranazeiro tem grande importância social e econômica na região do município de Maués. Visando o aumento da produtividade da lavoura, são necessários estudos sobre a população de plantas por unidade de área cultivada. Este trabalho teve como objetivo avaliar os efeitos de diferentes estandes de plantas no cultivo do guaranazeiro sobre aspectos de crescimento vegetativo, doenças, produtividade e fertilidade do solo, possibilitando uma melhor utilização das áreas utilizadas com a cultura do guaranazeiro, reduzir o impacto da implantação da cultura em novas áreas apresentando um retorno econômico aos produtores de guaraná do município de Maués, Estado do Amazonas. Foram estudados duas cultivares BRS-Amazonas e BRS-Maués em estandes de. 625, 833, 1.111, 1.666, 2.500 e 5.000 plantas por hectare. O delineamento experimental adotado para a análise foi o inteiramente casualizado em arranjo fatorial 2 x 6, sendo que o número de repetições variou de 3 a 10, de acordo com as variáveis estudadas. O aumento do estande de plantas mostrou viabilidade econômico-financeira para todos os indicadores, com baixo risco de obter resultados desfavoráveis na região analisada quando utilizadas cultivares que apresentem alta resistência às principais doenças que afetam a cultura. Existe a necessidade de se definir o estande ideal de plantas por unidade de área, considerando o tempo de estabilização da produção que ocorre a partir do quinto ano.

No sistema de Integração Lavoura Pecuária, o nitrogênio é o nutriente que mais limita o desenvolvimento, produtividade e biomassa da maioria das culturas. Sendo assim, é necessário desenvolver estratégias de manejo que contribuam para aumentar a eficiência de aproveitamento do nitrogênio. O objetivo do trabalho é avaliar, em condições de campo, as produtividades do milho cultivado sob pastagem de capim Braquiária com aplicação em pré-semeadura de níveis de nitrogênio. O trabalho foi desenvolvido na Fazenda Água Limpa da Universidade de Brasília, em um Latossolo Vermelho-Amarelo Distrófico típico, utilizando a pastagem do capim Braquiária como cultura antecessora. Foram realizados a adubação corretiva de 1448 Kg ha-¹de Calcário dolomítico, 120 Kg ha-¹ de P2O5, 100 Kg ha-¹ de K2O. O nitrogênio, na forma de uréia, foi aplicado em sulcos feitos na pastagem com 5 níveis de nitrogênio em pré-semeadura do milho: 0; 30; 60; 90 e 120 Kg ha-1 de N. Após a aplicação dos níveis de N no capim foi feita a dessecação da parte aérea com herbicida de contato na dose de 3 litros por hectare. Na semeadura do milho acrescentou-se mais 30 Kg ha-1 de N perfazendo os níveis: 0, 30, 60, 90, 120, 150 Kg de N ha-1 e a adubação de 120 Kg ha-¹ de P2O5, 100 Kg ha-¹ de K2O e 50 Kg ha-¹ de sulfato de zinco recomendada para o plantio da cultura do milho nos Cerrados. Os atributos analisados foram: massa seca do grão de milho a 13% de umidade; a massa seca da parte aérea do milho aos 90 dias após a semeadura; o teor de nitrogênio na folha do milho, o teor de nitrogênio no grão, o teor de clorofila nas folhas no momento da inflorescência com o auxilio do equipamento SPAD e a massa seca da parte aérea do capim Braquiária aos 45 dias após a aplicação das doses de N em pré-semeadura do milho. Os resultados obtidos tanto do milho como do capim Braquiária foram submetidos a analise de variância, aplicados o teste de significância e curvas de respostas. Na dose de 150 Kg ha-1de N aplicado antecipadamente proporcionou uma produção de 8 ton de massa de grãos a 13% de umidade, 10 t de massa seca da parte aérea, uma concentração de 3,2% de N nas folhas do milho e 0,8% de N no grão do milho. No capim Braquiária observou-se uma produção de 34 ton ha-1 na dose de 120 Kg ha-1de N. Os atributos avaliados mostraram que todos os resultados tiveram respostas lineares e significativas ao aumento das doses de N e observou-se, pelo teor de N nas folhas e na leitura do SPAD, que as planta de milho apresentaram estados normais de nutrição com a adubação antecipada. _________________________________________________________________________________________ ABSTRACT
Regarding the Crop Livestock integration system, nitrogen is the nutrient that most limits the development, productivity and biomass of most crops. Therefore, the development of management strategies which contribute to a higher efficiency of nitrogen are necessary. The objective of this study is to evaluate, under field conditions, within the Crop Livestock integration system, the corn productivity grown under pasture with application in pre-sowing with different levels of nitrogen.The work was developed at the University of Brasilia`s Farm, in a typical Dark Yellow Latosol, using the pasture of Braquiária grass as predecessor culture.A corrective fertilization was made using 1448 kg ha-¹ Limestone, 120 Kg ha-¹ P2O5, 100 kg ha-¹ of K2O and nitrogen was applied in the form of urea in grooves made in the pasture with 5 levels of nitrogen corn`s in pre-sowing: 0, 30, 60, 90 and 120 kg ha-1 of N. After the application of the different levels of N, the drying of the aerial part was made with contact herbicide in the dose of 3 litres per hectare. In the corn sowing were added other 30 kg ha-1 of N, comprising the levels: 0, 30, 60, 90, 120, 150 kg N ha-1 and fertilization of 120 Kg ha-¹ P2O5, 100 kg ha-¹ K2O, and 50 kg ha-¹ zinc sulfate, as recommended for the Cerrado. The attributes analyzed were: net weight of the corn grain under moisture of 13%, the net weight of the aerial part of the corn 90 days after sowing, the amount of nitrogen in the corn leaves, the amount of nitrogen in the grain, the amount of chlorophyll in the leaves at the time of inflorescence, measured with the SPAD equipment and net weight of the aerial part of Braquiaria grass 45 days after the application of the N in corn pre-sowing. The results of both the corn and the Braquiaria grass went through analysis of variance, test of significance and curves of answers. The dose of 150 kg ha-1 N applied beforehand provided a production of 8 tons net weight of grains at 13% moisture, 10 tons of net weight of aerial part, a concentration of 3.2% of N in the leaves of corn and 0.8% of N in corn grain. In braquiaria grass there was a production of 34 kg ha-1 at the dose of 120 kg ha-1 of N. The attributes evaluated showed that all results had significant and linear responses to the increase of N rates, and it was observed, by the content of N in the leaves and readings from SPAD, that the corn presented normal state of nutrition with the early fertilization.

Abstract:
As alterações do uso do solo processam-se de forma natural ou mediante alterações induzidas pelo Homem, tratando-se de um processo evolutivo do desenvolvimento dos ecossistemas e das civilizações. Neste trabalho, desenvolveram-se metodologias que resultaram numa aplicação informática (SIMLU), a qual implementa um modelo de interação espacial do uso do solo, com o propósito de analisar as relações entre o Homem, a economia e o ambiente, de forma a entender como determinados fatores edafoclimáticos, económicos, tecnológicos, demográficos e regulamentares, influenciam a ocupação e o uso do solo. O modelo permite simular a ocupação do solo ao longo do tempo e do espaço, face a cenários de mudanças climáticas, distribuindo emprego por sector de atividade e população pelas diferentes zonas consideradas, gerando repercussões na ocupação do território, na estrutura socioeconómica das populações e no valor da terra. A partir dos cenários de alterações climáticas (RCP4.5 e RCP8.5), previstos no Quinto relatório de avaliação do Painel Intergovernamental para as Alterações Climáticas (AR5- IPCC), aplicou-se o SIMLU a dois casos de estudo com características distintas: Tahaddart no Nordeste de Marrocos e na ilha Terceira no Arquipélago dos Açores. O modelo foi calibrado e validado para cada um dos dois casos de estudo, onde progressivamente foram introduzidas melhorias ao nível da capacidade de cálculo, análise e apresentação dos resultados, passando desde a primeira versão em formato Excel® (SIMLU V1.0), para a versão atual (SIMLU V2.0) numa aplicação autónoma e independente com interface gráfica para utilizadores. Para o caso de estudo de Tahaddart e áreas adjacentes, foram considerados para cada cenário RCP’s (horizonte temporal de 2099) dois tipos de sub-cenários: ocupação do uso do solo com base na estrutura produtiva e das aptidões de referência (2011) e ocupação do território através substituição do uso. Para cada cenário tratado, face à situação de referência, verificou-se uma diminuição da população que variou entre os 6818 e os 14244 habitantes (RCP4.5) e entre 48991 e os 43974 habitantes (RCP8.5). Para o caso de estudo aplicado á ilha Terceira, utilizou-se unicamente o cenário regionalizado RCP8.5 (horizonte temporal de 2099), não sendo admitido a substituição de uso relativamente à variação das normais climatológicas utilizadas (temperatura média anual e precipitação anual acumulada). Foi ainda considerado a redução dos postos de trabalho na Base Área das Lajes - BA4. Estimou-se os impactos na população e no valor da terra, resultante das alterações climáticas e da BA4. Dos resultados obtidos, verificase uma considerável redução da área de pastagem, que resulta na perda direta de cerca de 195 empregos ligados ao sector da pecuária a que se juntam 285 postos de trabalho suprimidos na BA4. O cenário simulado traduz-se numa diminuição de 2599 habitantes (cerca de 4% da população da Terceira em 2011) e um decréscimo global do valor da terra de cerca de 524 milhões de euros. O SIMLU apresenta-se assim como uma ferramenta de apoio à decisão, replicada em regiões e contextos diferentes, numa perspetiva de avaliar impactos na ocupação do uso do solo perante diferentes cenários de alterações climáticas; ABSTRACT: Spatial Interaction Model – A Tool for Land Analysis and Planning Land use changes are a result of natural or human induced changes, being an evolutionary process of ecosystems and civilizations. Methodologies were developed in this work, resulting in computer program (SIMLU) which implements a spatial interaction model of land use, with the aim of analyzing the relations between Man, the economy and the environment, and how edaphoclimatic (that affect land suitability), economic, technological, demographical factors and policies, can influence land use. The model allows us to simulate land use, through time and space, given climatic changes, distributing employment for activities and population for each considered zones, generate impacts in land use, socioeconomic structure of the populations and in the land value. Starting with the land use scenarios (RCP4.5 e RCP8.5), presented in the Fifth report of the Intergovernmental Panel for Climate Change (IPCC), SIMLU was applied in two case study areas with different characteristics: Tahaddart (Morocco) and Terceira island (Azores, Portugal). The model was calibrated and validated for each of the case study areas, improving on the calculation, analysis and outputs, starting from a Excel worksheet until arriving in the current form, an independent application with a user’s graphical interface. For each of the case studies, different outputs were presented allowing analysis of the model, as a decision support tool, which can be replicated for different contexts facing the evaluation of the impact of land use policies. Two types of sub-scenarios were considered in each RCP’s scenario, to Tahaddart basin: field occupation, based on productive structure and reference skills (2011) and occupation of the use replacement. In both scenarios, there was a population decrease raging 6818- 14244 habitants to RCP4.5 and 48991-43974 habitants to RCP8.5 scenario. For the case study applied to Terceira Island, only RCP8.5 was used for the temporal horizon to 2099, not admitting the use replacement relatively to the climatological norms used (average annual temperature and accumulated annual rainfall). The reduction of the working places in Air Base of Lajes- BA4, was also considered. The land values and the impact in population resulting from the climate changes and from the BA-4 was estimated. From the obtained results, a considerable decrease from the pasture area (resulting from the direct loss of the 195 jobs connected to the livestock) in which is added 285 jobs lost in BA-4. The simulated scenario indicates a diminution in the number of habitants, around 2599 (about 4% of the population in 2011) and a global decrease of the land value around 524 million euros. SIMLU presents as a support tool to decision, which can be replicated in different circumstances, concerning different scenarios in a way to evaluate the impacts of territory occupation regarding different climatic changes scenarios.

Abstract:
Las Finanzas Públicas presentan una evolución consistente con la Economía en general. La siguiente cita ilustra esta idea: “si este libro se hubiera escrito hace veinticinco años, se habría titulado Hacienda Pública y habría girado en torno a las fuentes de los ingresos fiscales. El título Economía del Sector Público y el mayor alcance que implica no son, sin embargo, accidentales. En los últimos años, el gasto público ha alcanzado niveles históricos y actualmente representa en países occidentales cifras próximas o superiores a un tercio del producto nacional bruto. […] Durante ese periodo, la teoría económica del sector público ha florecido” (Stiglitz, 1988). Los nuevos desarrollos de la disciplina han dado lugar a nuevas teorías y enfoques, sobre todo en el ámbito del gasto público y tributación óptima. Rosen y Gayer (2010) sostienen que uno de los logros más importantes en el campo de la Hacienda Pública ha sido precisamente la integración más estrecha del análisis del gasto público y de la imposición con la teoría económica básica. El estudio de las Finanzas Públicas comprende (i) el conocimiento de las actividades que realiza el sector público y la forma en que están organizadas; (ii) el entendimiento y la anticipación, en la medida en que ello sea posible, de las consecuencias de las actividades del gobierno; (iii) la evaluación de alternativas de política. Se espera que este libro contribuya con algunos de estos tópicos. Más allá de la teoría, el abordaje de problemas prácticos viene siendo cada vez más relevante, y se refleja en la enseñanza. Como señala Gruber (2010), refiriéndose a su libro, “esta publicación debería ayudar a los estudiantes a entender los problemas de finanzas públicas que son discutidos todos los días en la tapa de los diarios”. La vinculación de los aspectos conceptuales con los prácticos es algo que se viene realizando en la Cátedra Finanzas Públicas II (Argentina) en la Facultad de Ciencias Económicas de la Universidad Nacional de La Plata, mediante la realización de trabajos prácticos que contrastan los tópicos teóricos con casos concretos y actuales, derivados de la implementación de políticas públicas. Por esta vía se busca ilustrar los conceptos y facilitar su mejor comprensión, y especialmente, motivar en el alumno el análisis crítico y la discusión de la realidad.

Abstract:
3000. That's the number of marketing messages the average American confronts on a daily basis from TV commercials, magazine and newspaper print ads, radio commercials, pop-up ads on gaming apps, to pre-roll on YouTube videos and native advertising on mobile news apps. These commercial messages are so pervasive that we cannot help but be affected by perpetual come-ons to keeping buying. Over the last decade, advertising has become more devious, more digital, and more deceptive, with an increasing number of ads designed to appear to the untrained eye to be editorial content. It's easy to see why. As we have become smarter at avoiding ads, advertisers have become smarter about disguising them. Mara Einstein exposes how our shopping, political and even dating preferences are unwittingly formed by brand images and the mythologies embedded in them. Advertising: What Everyone Needs to Know® helps us combat the effects of manipulative advertising, and enables the reader to understand how marketing industries work in the digital age, particularly in their uses and abuses of Big Data. Most importantly, it awakens us to advertising's subtle and not so subtle impact on our lives-both as individuals and as a global society. What ideas and information are being communicated to us-and to what end?

Abstract:
Recent discussion, academic publications and many of the national exhibitions relating to the Great War at sea have focused on capital ships, Jutland and perhaps U-boats. Very little has been published about the crucial role played by fishermen, fishing vessels and coastal communities all round the British Isles. Yet fishermen and armed fishing craft were continually on the maritime front line throughout the conflict; they formed the backbone of the Auxiliary Patrol and were in constant action against U-boats or engaged on unrelenting minesweeping duties. Approximately 3000 fishing vessels were requisitioned and armed by the Admiralty and more than 39,000 fishermen joined the Trawler Section of the Royal Naval Reserve. The class and cultural gap between working fishermen and many RN officers was enormous. This book examines the multifaceted role that fishermen and the fish trade played throughout the conflict. It examines the reasons why, in an age of dreadnoughts and other high-tech military equipment, so many fishermen and fishing vessels were called upon to play such a crucial role in the littoral war against mines and U-boats, not only around the British Isles but also off the coasts of various other theatres of war. The book analyses the nature of the fishing industry's war-time involvement and also the contribution that non-belligerent fishing vessels continued to play in maintaining the beleaguered nation's food supplies.

Abstract:
This chapter discusses C. Francis Jenkins' life and work, calling him a visionary for his breakthrough inventions in film and television. In a world of dramatic change in motion pictures and television, Jenkins was a pioneer. In film, he sold his controversial Phantoscope projector patent, which led to large-screen movie projection. In television, he bridged mechanical with electronic technology, later experiments related to fiberoptics, and electro-optical receivers. He was the only inventor who participated in the birth of both motion-picture photography and television. Over the period of 1894 through 1933, Jenkins filed nearly 300 patents, several granted after his death. This chapter provides an overview of Jenkins' youth, focusing on how his agrarian upbringing created within him an independent will, an untiring work ethic, and strong character. It then describes Jenkins' traits as a man, his legacy as an inventor, his career as entrepreneur and businessperson, and his works as an author. It also reflects on the relationship between Jenkins' approach of the late 1920s and modern technology.

Abstract:
The development of lead zirconate titanate (PZT) films can be a fairly troublesome process when trying to obtain a viable thick crack-free film. Traditional methods for film fabrication via a pure sol-gel solution provide the best results, but still can have many problems. This paper maps out the specific spin-coating and annealing steps used in order to achieve a PZT film with minimal-to-no cracking and/or delamination. A seed layer of PbTiO3 (PT) was used in order to create nucleation sites for the subsequent PZT layers, virtually eliminating any delamination. All layers, including the PT base layer, were spin-coated at 3000 rpm onto a 100-mm silicon wafer (previously sputtered with Ti and Pt for adhesive and conductive purposes, respectively) and soft-baked at 150 °C for 10 min. Initial annealing procedures produced severe cracking, a result of the relatively high cooling rates through the Curie temperature (∼350 °C). The annealing process was refined, for individual layers, to 550°C for 120 s, with a cooling rate of 0.042 °/s between 400 and 300 °C. Final annealing was conducted at 600 °C for 30 min, with a cooling rate of 0.028 °/s between 400 and 300 °C. The resulting PZT layer was virtually crack-free. Platinum was sputtered again subsequent to PZT deposition in order to pole the piezoelectric material. A PZT/nanoparticle powder mixture was also investigated as the piezoelectric layer. PZT nanoparticles were suspended in the sol-gel precursor solution and then spin-coated also at 3000 rpm onto a 100-mm wafer and soft-baked at 150 °C for 10 min. The relatively slow cooling rate was extended between 500 and 100 °C in order to prevent any cracking that might occur along grain boundaries between the individual PZT nanoparticles. The resulting film was crack-free, however displaying areas of agglomerated nanoparticles.

Abstract:
In the past years, many studies had been carried out in the ITREC Plant, located in ENEA – Trisaia Research Centre, in the field of nuclear fuel reprocessing and with re-fabrication techniques to the Th-233U cycle as an alternative to the U-Pu cycle. During these activities low level solid wastes were produced, containerised, stored into trenches and progressively covered with earth. In the 1980’s the trenches were reclaimed obtaining 3000 drums (200 liter volume) of solid LLW and about 6000 drums of low contaminated soil. In this presentation are described the action of reclamation of the trenches, sealing the low contaminated soil, and the melting campaign of contaminated drums.

Abstract:
The AGN reactor type was supposed to be a workhorse of nuclear education in the sixties, with dozens of units being produced and sold around the USA and overseas. However, nowadays only 4 units are fully operational, the rest has been mothballed or decommissioned. In 2010 Texas A&M University made the AGN-201M again part of its education program, after years of reactor inactivity. This very recent practical experience from Texas A&M shows that AGN-201M can be successfully used for undergraduate and graduate nuclear education and new educational methods can be implemented on the reactor. The paper demonstrates new experimental classes developed for the reactor and may serve as an idea for other mothballed AGNs or training reactors worldwide.

Full text
Abstract:
Metallic residues are distributed heterogeneously onto small-arms range soils from projectile fragmentation upon impact with a target or berm backstop. Incremental Sampling Methodology (ISM) can address the spatially heterogeneous contamination of surface soils on small-arms ranges, but representative kilogram-sized ISM subsamples are affected by the range of metallic residue particle sizes in the sample. This study compares the precision and concentrations of metals in a small-arms range soil sample processed by a puck mill, ring and puck mill, ball mill, and mortar and pestle prior to analysis. The ball mill, puck mill, and puck and ring mill produced acceptable relative standard deviations of less than 15% for the anthropogenic metals of interest (Lead (Pb), Antimony (Sb), Copper (Cu), and Zinc (Zn)), with the ball mill exhibiting the greatest precision for Pb, Cu, and Zn. Precision by mortar and pestle, without milling, was considerably higher (40% to >100%) for anthropogenic metals. Media anthropogenic metal concentrations varied by more than 40% between milling methods, with the greatest concentrations produced by the puck mill, followed by the puck and ring mill and then the ball mill. Metal concentrations were also dependent on milling time, with concentrations stabilizing for the puck mill by 300 s but still increasing for the ball mill over 20 h. Differences in metal concentrations were not directly related to the surface area of the milled sample. Overall, the tested milling methods were successful in producing reproducible data for soils containing metallic residues. However, the effects of milling type and time on concentrations require consideration in environmental investigations.
