Abstract It is shown that in some non-discrete topological spaces, discrete subspaces with certain cardinality are C-embedded. In particular, this generalizes the well-known fact that every countable subset of P-spaces are C-embedded. In the presence of the measurable cardinals, we observe that if X is a discrete space then every subspace of υ X (i.e., the Hewitt realcompactification of X) whose cardinal is nonmeasurable, is a C-embedded, discrete realcompact subspace of υ X. This generalizes the well-known fact that the discrete spaces with nonmeasurable cardinal are realcompact.

Previous issue date: 2010-04-09This research intended to answer to the question: how was the implementation of the extension of the obligedness politics of the fundamental schooling given for the six year-old population in municipal schools of Dourados, Mato Grosso do Sul. The objective was to know the local configuration of that politics in relation to municipal and national regulations and orientations, with special attention to the measures taken by the schools concerning the organization of time, space and curriculum. For so much, it was accomplished a qualitative investigation in the three municipal schools that obtained the largest numbers of registrations in the first year in the fundamental teaching during the years of 2007 to 2009. It was used information obtained through interviewing pedagogic coordinators and responsible technicians for the fundamental teaching in the Municipal Bureau of Education of Dourados submitted to content analysis. Those information were compared with national and municipal official legislation, regulation and orientations, by document analysis. The qualitative approach was enriched with statistical data from INEP and by consultation to bibliographical sources about the subject. The results showed that in the observed municipal schools the implementation of the politics in focus is recent, being marked by the improvisation, for the lack of infrastructure and pedagogic conditions that difficult the organization of space, time and curriculum in consonance with national orientations. Few were the changes in the school atmosphere to assist the six year-old child. Thus, the educational installment propitiated by the extension of the fundamental teaching politics implemented in Dourados hasn t been effecting the child's fundamental rights assured in the legal sphere and evidence the scarce local consequence of MEC initiatives
Esta pesquisa buscou responder à pergunta: como se deu a implementação da política de extensão da obrigatoriedade do ensino fundamental para a população de seis anos de idade em escolas municipais de Dourados estado de Mato Grosso do Sul? O objetivo foi conhecer a configuração local dessa política vista em relação às regulamentações e orientações municipais e nacionais, com especial atenção às medidas tomadas pelas escolas no tocante à organização do tempo, espaço e currículo. Para tanto, realizei investigação qualitativa em três escolas municipais, que obtiveram maior número de matrículas no primeiro ano no ensino fundamental entre os anos de 2007 e 2009. Utilizei informações obtidas por meio de entrevistas a coordenadores pedagógicos e técnico responsável pelo ensino fundamental na Secretaria Municipal de Educação de Dourados valendo-me da análise de conteúdo. Essas informações foram cotejadas com legislação, regulamentação e orientações oficiais nacionais e municipais, por meio de análise de documento. A abordagem qualitativa foi enriquecida com dados estatísticos do INEP e pela consulta a fontes bibliográficas que tratam da questão. A pesquisa mostrou que nas escolas municipais observadas a implementação da política em foco é recente, sendo marcada pela improvisação, pela falta de condições infraestruturais e pedagógicas que entravam a organização do espaço, do tempo e currículo em consonância com orientações nacionais. Poucas foram as mudanças ocorridas no ambiente escolar para atender à criança de seis anos de idade. Desse modo, a prestação educacional propiciada pela política de extensão do ensino fundamental implementada no município tem deixado de efetivar direitos fundamentais da criança assegurados na esfera legal e evidenciado a escassa consequência local das iniciativas do MEC.

Texto completo da fonteResumo:
A Serra da Bodoquena constitui um planalto carbonático desenvolvido nas rochas do Grupo Corumbá (Neoproterozóico III - Faixa Paraguai), que se ressalta topograficamente das planícies do estado do Mato Grosso do Sul. A análise morfológica em escala 1:60.000 permitiu compartimentar o carste da Serra da Bodoquena em três unidades principais. A primeira corresponde a um carste de recarga mista (predominantemente autogênica) com formas de carste labiríntico e carste poligonal desenvolvidas em calcários, situada no Planalto da Bodoquena. A segunda corresponde a um carste de recarga essencialmente autogênica, com morfologia de morros residuais e planícies cársticas com dolinas, composta principalmente de dolomitos, situada na Depressão do Rio Miranda. A última consiste de um carste interestratal desenvolvido sob os arenitos da Formação Aquidauana da Bacia do Paraná, no extremo sul da Serra da Bodoquena, situada na Depressão do Rio Miranda, com a presença de dolinas em arenitos. Apesar do sistema cárstico da Serra da Bodoquena possuir um aqüífero de condutos bem desenvolvido, evidenciado pelas nascentes cársticas, vales cegos no setor noroeste, dolinas e poços de abastecimento produtivos, as cavernas são pouco freqüentes e com pequeno desenvolvimento. Observam-se quatro padrões principais de cavernas, que ocorrem associados aos compartimentos de relevo: 1) salões de abatimento irregulares em planta e formando planos inclinados em seção longitudinal, as vezes se estendendo por até 90 m abaixo do nível d\'água, na unidade dos morros residuais dolomíticos; 2) cavernas em rede anastomosada em planta, com condutos circulares a elípticos e ramificações anastomosadas em seção transversal em calcários, na unidade do carste labiríntico e carste poligonal e raramente em morros residuais e planícies; 3) cavernas meandrantes em planta, as vezes associados a sumidouros ativos ou inativos, com injeção alogênica na maioria dos casos em calcários na Unidade do carste labiríntico e carste poligonal; 4) Nascentes do tipo vauclusiana nas planícies de calcários, principalmente junto a escarpa leste do Planalto da Bodoquena. A existência de tectônica recente na Serra da Bodoquena foi constatada a partir de feições como: espeleotemas subaéreos submersos pelo menos a 16 m de profundidade abaixo do nível d\'água mínimo da variação sazonal; planalto escarpado sustentado por calcários e planícies por dolomitos; porção norte do planalto com rios mais entalhados que o sul; estrutura linear relacionada à borda do Pantanal, que cruza a Serra da Bodoquena, observada em escala 1:250.000.The Bodoquena plateau, developed over the Corumbá Group (Neoproterozoic III - Paraguai Fold Belt), is a carbonate rock highland relative to the non carbonate lowlands of the Mato Grosso do Sul State, mid-western Brazil. Based on 1:60.000 scale morphological analysis of the karst topography, three main compartments were defined. The first one is a mixed recharge karst landforms, developed over limestone of the Bodoquena plateau. The second unit is characterized by essentially autogenic recharge, residual hills and karstic plains with dolines, developed mainly over dolomites of the Miranda river depression (lowlands). The third one, characterizes an interstratatl karst system in proterozoic limestones overlain by sandstones of the Aquidauana Formation of the Phanerozoic Paraná basin. This geomorphological unit is localized at the southern extremity of the Bodoquena plateau, exhibiting flat topography, with frequent dolines in sandstone, of up to 700 m in diameter. Although the Bodoquena karst system is well developed, as can be inferred based on the presence of several vauclusian springs, blind valleys in the northwest border, dolines and a deep conduit aquifer evidenced through productive water wells, the cave incidence is low as are their dimensions, considering the large carbonate rock exposure. Four cave patters were recognized, which are related to the above geomorphological units: 1) large irregular breakdown halls in plain view and dipping planes in longitudinal section (following bedding and joint surfaces), which frequently reach up to 90 m beneath the water table, sometimes with large lakes, as for example, the Lago Azul cave (Bonito municipality). This pattern is the most frequent cave type of the second unit, occurring at the dolomitic residual hills with karst plains; 2) network caves with anastomotic pattern in plan view and circular to elliptical conduits with lateral anastomosis in cross section. They occur mostly associated with the labyrinth and polygonal karst topography of the first morphological unit and rarely with the unit of residual hills and plains; 3) caves with meandering conduits in plan view, sometimes with active or inactive allogenic stream sinks, associated with the polygonal and labyrinth karst topography; 4) Steep dipping phreatic conduits, characterizing vauclusian springs, occurring at the limestone plain along the base of the eastern escarpment of the Bodoquena plateau. The recent tectonic activity along the Bodoquena plateau area was detected by the following features: vadose speleothems submerged at least 16 m beneath the lowest seasonal water level stage; limestone highland with the escarpment beside dolomitic lowlands; northern part of the carbonate plateau with deep entrenched river valleys in contrast with the southern sector of open valleys and less entrenchment; linear structure observed in 1:250.000 scale which marks the border of the Pantanal basin and crosses the Bodoquena plateau.

Cette thèse présente l’édition critique du Mystère des trois doms (1509), d’après un manuscrit unique aujourd’hui conservé à la Bibliothèque nationale de France sous la cote n.a.f 18995. Ce texte dramatique en moyen français d’environ 11000 vers raconte la conversion puis le martyre des trois saints patrons de la ville de Romans, Séverin, Exupère, et Félicien ; il a été composé en vue d’une représentation, qui eut lieu trois jours durant dans cette même ville les 27, 28 et 29 mai 1509. Notre travail comporte plusieurs aspects distincts et complémentaires : une analyse philologique et historique, une présentation littéraire et une étude linguistique. Après avoir présenté les objectifs de notre travail, nous analysons la préparation de la représentation de 1509, tant du point de vue de l’écriture du mystère (analyse du manuscrit et des différentes étapes de sa composition) que du point de vue de la réalisation matérielle de l’entreprise (construction du théâtre et des décors). Nous possédons en effet également le livre des comptes du mystère, qui contient de précieuses informations sur les modalités d’organisation de sa représentation : il s’agit d’un cas unique, ce texte est donc d’une grande importance pour l’histoire du théâtre en France. Nous proposons ensuite une présentation du texte du mystère, une analyse des sources, de la mise en scène, et quelques éléments de versification et de stylistique. La langue du mystère étant d’une grande richesse, notre étude linguistique s’intéresse à plusieurs aspects : les systèmes graphiques des différents scribes, la régionalité de la langue et la représentation de l’oralité. Nous présentons enfin les principes qui ont guidé l’édition critique des trois journées du mystère. Celle-ci est suivie d’un relevé des nombreuses variantes et corrections contenues dans le manuscrit, de notes portant sur le texte, d’un glossaire et d’une bibliographie ; le volume contient enfin en annexes plusieurs planches du manuscritThis thesis presents a critical edition of the Mystère des Trois Doms (1509), from a single manuscript now kept in the National Library of France under the reference n.a.f 18995. This drama play in Middle French contains approximately 11,000 verses, and tells the conversion and martyrdom of the three patron saints of the town of Romans, Séverin, Exupère and Félicien; it was composed for a performance, which took place in the city during three days, on 27, 28 and 29 May 1509. Our work includes several distinct and complementary aspects: philological and historical analysis, literary presentation and linguistic study. After presenting the objectives of our work, we analyze the preparation of the 1509 performance, from a writing point of view (analysis of the manuscript and the various stages of its composition) as well as from the material realization of the representation (construction of the theater and scenery). Indeed, we also have the book of accounts of the mystery play, which contains valuable informations on organizational modalities of its representation: it is a unique case, making this text of great importance for the history of the theater in France. We then propose a presentation of the text of the mystery, an analysis of sources, staging, and some elements of versification and stylistics. The language of the mystery being very rich, our linguistic study focuses on several aspects: graphics systems of the different scribes, regionality of the language and representation of orality. Finally, we present the principles that guided our critical edition of the three days of the play, followed by an account of the various variants and corrections contained in the manuscript, some notes on the text, a glossary and a bibliography. The appendices of the volume also contain several boards of the manuscript

Texto completo da fonteResumo:
O objetivo principal desse trabalho foi a análise dos fósseis, no contexto temporal e paleoambiental, em unidades sedimentares da Faixa Paraguai (grupos Jacadigo e Corumbá, formações Araras e Raizama), nas regiões de Corumbá e Bonito- serra da Bodoquena, MS, e de Cáceres Bauxi/Jangada, MT. O conjunto paleontológico destas sequências é de grande importância para o melhor entendimento cronológico da transição Proterozóico/Cambriano em território brasileiro. Os fósseis presentes incluem megafósseis (metazoários e metáfitas), microfósseis e estromatólitos, embora de ocorrência restrita. No Grupo Jacadigo foram encontrados microfósseis (melanocirilídeos) em clastos carbonáticos, que, no registro mundial estão limitados ao intervalo entre 950 e 700 Ma. A maior diversificação fossilífera está presente na Formação Tamengo, a unidade superior do Grupo Corumbá, com metazoários (Cloudina Iucianoi e Corumbella Werneri), metáfitas (Tyrasotaenia sp.), microfósseis (Sphaerocongregus variabilis) que, em conjunto apontam para uma idade vendiana superior para esta sequência sedimentar. Na Formação Araras, unidade considerada equivalente ao Grupo Corumbá, os quatro tipos de estromatólitos encontrados não fornecem indicações de idade, apenas informações de cunho paleoambiental. Os icnofósseis, pouco conhecidos no registro paleontológico do Pré-Cambriano do Brasil, foram descritos, pela primeira vez, nos sedimentos arenosos da Formação Raizama, e incluem formas horizontais, simples, semelhantes aos assinalados no final do Proterozóico. As análises isotópicas de \'delta\'\'ANTPOT.13 C\' mostraram valores coerentes com os de sequencias mundiais do final do Vendiano e também puderam complementar os estudos paleoambientais, ao lado das evidências fornecidas pelo conjunto litológico e de estruturas sedimentares, e algumas análises de \'delta\'\'ANTPOT.18 O\'. As composições isotópicas de Sr isoladamente concordaram com valores registrados no Proterozóico Superior, mas, associadas às evidências paleontológicas podem sugerir um intervalo de idade mais restrito ao final desse eon.This dissertation describles fossils and their temporal and paleoenvironmental contexts from the Jacadigo and Corumbá Groups and Araras and Raizama Formations of the Paraguai Belt in the regions of Corumbá and Bonito/serra da Bodoquena, Mato Grosso do Sul, Cáceres and Bauxi/Jangada in Mato Grosso, in Central-Western Brazil. The paleontologic record of these sequences is of great importance for a better understanding of the Proterozoic Cambrian transition in Brazil. The fossils studied include metazoans, metaphytes, organic-walled microfossils, ichnofossils and stromatolites, all of rather limited occurrence. Within the Jacadigo Group, vase-shaped microfossils apparently restrict the age of the carbonate clasts in which they occur to the interval between 700 and 950 Ma. Greater paleontological diversity is displayed by the overlyng Corumbá Group in the form of metazoans (Cloudina Lucianoi and Corumbella werneri), metaphytes (tyrasotaenia sp.) and microfossils (Sphaerocongregus variabilis), that together point to a latest Vendian age at least for the uppermost part of this sedimentary sequence. In the Araras Formation, a lateral equivalent of the Corumbá Group, stromatolites provide no significant indication of age but are of considerable paleoenvironmental interest and may be useful in local correlation. Above the Araras Formation, in the Raizama Formation, simple, horizontal ichnofossils are here registered for the first time in the Paraguai Belt and are forms known elsewhere from the end of the Proterozoic although not necessarily restricted to this eon. Isotopic analyses of the stable isotopes of C in limestone of the Corumbá Group and Araras Formation furnished \'delta\'\'ANTPOT.18 C\' values consistent with those exhibited by other terminal Vendian sequences in the world, they also complement paleoenvironmental studies, together with evidence derived from study of lithologies, sedimentary structures and a few analyses of \'delta\'\'ANTPOT.18 O\'. Isotopic compositions of Sr for many of the same samples analysed for C and O fall within the general range of values known for the Late Proterozoic, in conjunction with the associated fossil evidence, however, they appear to be consistent with a more restricted interval at the end of this eon.

Texto completo da fonteResumo:
En premier lieu, nous evoquons le cadre conjonctuel dans lequel ces miracles ont ete representes : il ne peut etre indifferent qu il s agisse de pieces d inspiration religieuse, qu elles aient ete jouees de 1339 a 1382 et que leurs commanditaires aient ete la riche confrerie des orfevres de paris. Aussi evoquerons nous la conjoncture dans laquelle ils sont nes : la guerre de cent ans, la situation economique et surtout le contexte religieux, la montee en puissance de la bourgeoisie parisienne et plus particulierement, la corporation des orfevres. Nous presentons ensuite le recueil du cange et ses principales caracteristiques. Ces quarante mircles possedent un point commun qui apparait d emblee : dieu et ou nd interviennent toujours - quoique a des degres divers - dans leur dramaturgie. Ces interventions divines apparaissent motivees par les liens existant entre createur et creature, par le regard que porte le createur sur l attitude de sa creature : vis a vis du respect qu elle lui doit, mais aussi envers ses semblables, autres creatures de dieu, dont la vie interfere avec la sienne. Il doit toujours avoir a l esprit que son salut eternel est en jeu ; les interventions divines sont destinees a le lui rappeler. Entre eux existe un contrat : l eternel contrat. Nous definissons ensuite la methodologie adoptee pour l analyse individuelle des miracles en vue d etablir les liens existant entre leur dramaturgie et leur propos religieux enfin, a la suite de ces etudes individuelles, nous determinons la nature de la spiritualite qui aOur purpose is to establish the kinds of bonds existing between the dramatic art of the forty miracles de notre dame par personnages and the spiritual conception of their sleeping partners. At first, we recall the conjoncture space in wich those miracles were played : the religious theme is not unimportant in the plays, as they were stage from 1339 to 1382 and that their sleeping partners were the rich confrerie des orfevres de paris. Thus we evoke the conjoncture in which they were born : the one hundrerd years war, the economic situation and especially the religious context, the increasing power of the parisian burgesses and, more particulary the corporation of goldsmiths. After, the main characteristics of the recueil du cange are presented. Those forty miracles have a striking common point : god and or the virgin always break in - although in varied degrees - on their dramatic art. Those divine interventions always appear justified because of the bonds between creator and creature, by the creator's sight of his creature's attitude : about the respect it should have towards creator and about the others god's creatures from whom life interfere with its one's it always must have in its mind that its eternal salvation is at stake ; the divine interventions are intended to remind them for it. Between them, exist a contract : the eternal contract. Then we define the methodology used for the individual analysis of miracles with a view to

Texto completo da fonteResumo:
A região da serra da Alegria, parte do extremo sul do Cráton Amazônico, com extensão de cerca de 830 \'km POT.2\', foi estudada com métodos geológicos de campo, fotogeológicos e laboratoriais, mineralógico-petrográfico e litogeoquímicos, visando o mapeamento regional de reconhecimento (esc. 1:100.000), contribuições à evolução precambriana e verificações iniciais do potencial metalogenético. A área compreende de W para E a transição do Complexo Rio Apa, em partes de sua porção denominadas de Associação Metamórfica do Alto Tererê. A área é constituída em seus setores W e Central por um segmento crustal siálico, regionalmente contínuo, de gnaisses polimetamórficos de alto grau e metagranitóides intrusivos de tipo TTG, incluindo ainda rochas supracrustais compreendidas na Seqüência Metavulcano-Sedimentar Básica com características de tipo greenstone belt, tectonicamente inseridas nas rochas graníticas. Destacam-se nas porções basais dessa seqüência, metabasitos/anfibolitos com estruturas de lavas almofadadas bem preservadas e características geoquímicas de toleiitos de fundo oceânico, associados com xistos de metatufos básicos. A Intrusão Diferenciada Gabro-Anortosito-Granofírica da Serra da Alegria é parte de um vasto corpo magmático e o principal marco geomórfico da área de estudo, localizada no setor Central com extensão além dos seus limites N. Compreende duas séries magmáticas anorogênicas independentes, entretanto envolvidas em processos de mistura e contaminação. A primeira série, de gabros e anortositos predominantes, é toleiítica manto-derivada e sofreu processos de fracionamento durante a ascenção, assim como de diferenciação por cristalização fracionada em câmara magmática crustal relativamente rasa. A segunda compreende granofiros diversos, apresenta tendências alcalinas e é considerada de derivação crustal profunda. Metavulcanitos e Subvulcanitos e Subvulcanitos Ácidos e Metadiabásicos complementam o quadro petrográfico regional. A petrogênese dos metavulcanitos ácidos, dacitos/riodacitos e riolitos é problemática, existindo apenas indícios não-inequívocos, quanto as suas relações mútuas e com os metagranofiros da Intrusão da Serra da Alegria. Os metadiabásios encontrados em duas ocorrências apenas são considerados as rochas precambrianas mais jovens da região. O setor E constitui-se numa associação de gnaisses graníticos e xistos, incluindo possíveis equivalentes de rochas dos setores Central e W, com características tectônicas por excelência. Forma um bloco parautóctone e alóctone transportado de E para W, por processos orogênicos proterozóicos mais jovens de formação de faixa móvel. O metamorfismo regional progressivo (de W para E) de grau médio atingiu no extremo E condições máximas de facies anfibolito média transicionais para superior. Os principais metalotectos regionais são a Seqüência Metavulcano-Sedimentar Básica, com indícios isolados de Cu e potencial para Au emetais base, e a Intrusão Diferenciada da Serra da Alegria em sua parte magmato-estratigráfica inferior, de rochas básico-ultrabásicas e ultramáficas, com ocorrências isoladas de platinóides em gabros heterogêneos mais ricos em Cr e possíveis cromititos estratiformes e sulfetos magmáticos de tipo Ni-Cu-Fe, entre outros. A evolução geotectônica precambriana compreende quatro eventos principais incluindo três ciclos orogenéticos: (1) - formação dos gnaisses polimetamórficos TTG e eventualmente dos metagranitóides TTG intrusivos, em um ou mais processos metamórficos de alto grau e anatexia crustal arqueanos; (2) - formação e colapso tectono-metamórfico da bacia oceânica, possivelmente de tipo retro-arco da Seqüência Metavulcano-Sedimentar Básica arqueana ou paleoproterozóica; (3) - intrusão e diferenciação do complexo magmático gabro-anortosito-granofírico da serra da Alegria, paleo a mesoproterozóico, em regime de ) estabilidade crustal, incluindo eventualmente como fase final as rochas metavulcânicas ácidas, e (4) - desenvolvimento regional da faixa móvel de Associação Metamórfica do Alto Tererê constituindo o setor E da área, com idades mínimas mesoproterozóicas segundo dados geocronológicas da literatura.The Serra da Alegria region with an area of 830 km² is a part of the southernmost extremity of the Amazon Craton (Cráton Amazônico) located in Mato Grosso do Sul State, Brazil. It was studied by fieldwork and photogeology as well as by mineralogical, petrographical and geochemical laboratory methods. A regional lithostructural reconnaissance map at a scale of 1:100.000 and results concerning the Precambrian geological evolution and metallogenesis are presented. From W to E the study area encopasses the transition from stable Archean parts of the Craton to the adjoining portions of the Proterozoic mobile belt comprising the Alto Tererê Metamorphic Association (Associação Metamórfica do Alto Tererê) of the Rio Apa Complex (Complexo Rio Apa). According to the main lithostrutural features, the area was subdivided in into Western, Central and Eastern sectors. The Western and Central sectors are composed a regionally continuous major sialic crustal segment of high-grade polymetamorphic TTG-gneisses and intrusive TTG-metagranitoids. As minor tectonic inliers they host supracrustal rocks having greenstone-belt characteristics named the Basic Metavulcano-Sedimentary Sequence (Seqüência Metavulcano-Sedimentar Básica). Basal portions of the supracrustal sequence include basic metavolcanics, now amphibolites, with well-preserved pillow lava structures and geochemical properties of ocean floor tholeiites, associated with mafic schists derived from basic to intermediate tuffs. The differentiated plutonic to hypabyssal igneous intrusion of the Serra da Alegria forms the most prominent geomorphological marker of the study area. It intruded the sialic basement rocks throughout the northern half of the Central Sector, extending regionally to the north far beyond this sector. There occur two genetically unrelated anorogenic magmatic series locally involved in magmatic mixing and contamination processes. The first one comprises major cumulate and layered gabbros and anorthosites as well as minor felsic differentiates (as veins intruding the gabbros). These rocks formed by magma chamber differentiation through fractional crystallization under rather shallow crustal conditions (as shown by Sr-fractionation in the anorthosite plagioclases), from upper mantle tholeiitic gabbroic parental magmas subjected to the fractionation processes during mantle ascent. The second series consists of a huge amount of younger granophyres. These are felsic rocks of alkaline affinities inferred to have originated from lower-crust magmas. Acid metavolcanics and subvolcanics and metadiabases complete the regional petrographic spectrum. The petrogenesis of the acid metavolcanics, which include decites/rhyodacites and rhyolites, is still problematical, since only ambiguous evidence was found regarding their mutual relationships and those with the metagranophyres of the Serra da Alegria Intrusion. The metadiabases were observed in only two occurrences; they are low-grade metamorphic rocks considered to be the youngest Precambrian rocks of the region. Throughout the Eastern Sector occurs an intimate association of granitic gneisses and metapelitic to quartzose schists prominently tectonized, also including probable equivalents of rocks of the adjoining Central and Western sectors. The Eastern Sector represents a parautochtonous to allochtonous, E-to-W transported block, structured and amplaced in the course of the younger orogenic processes of the Proterozoic mobile belst. Progressive regional metamorphism from W to E in this sector is medium grade and reached - in the extreme E in this sector - maximum conditions, transitional from medium to upper amphibolite facies. The main regional matallotects are the Metabasic Volcano-Sedimentary Sequence of greenstone-belt characteristics and the Differentiated Layered Cu anomalies and an inferred potentiality for gold and base metals. The latter shows traces of platinum minerals in heterogeneous Cr-richer gabbros and an inferred potentiality for stratiform chromities and magmatic sulphides of the Ni-Cu-Fe type, among others, related to basic-ultrabasic and ultramafic lower portions of the intrusion. The Precambrian geotectonic evolution comprises four major events including three orogenic cycles: 1)-formation of the polymetamorphic TTG-gneisses and possibly the intrusive TTG-metagranitoids in the course of one or more Archean processes of high-grade metamorphism and crustal anataxis; 2)-generation and tectiono-metamorphic collapse of the oceanic (possibly back-arc) basin of the Metabasic Volcano-Sedimentary Sequence of greenstone-belt characteristics of Archean or Palaeoproterozoic age; 3)-emplacement and magmatic evolution of the layered intrusion of the Serra da Alegria in a period of crustal stability and tectonic calm of Paleo- to Mesoproterozoic age, including perhaps, as a final stage, the acid metavolcanics, and (4)-regional mobile belt development of the Alto Tererê Metamorphic Association affecting mainly the rocks of the Eastern Sector of the study area, with a Mesoproterozoic minimum age (of 1.7-1.6 Ga), as reported in geochronological studies in the literature.

Este trabalho aborda mapeamento geológico e a estratigrafia dos depósitos associados ao rio Paraná no segmento compreendido entre Porto Primavera (MS), a montante da foz do rio Piquiri. A metodologia empregada para sua elaboração compreendeu as técnicas tradicionais de fotointerpretação geológica adaptadas para formas deposicionais, tendo sido utilizadas imagens MSS e RADAR, e fotografias aéreas. Os trabalhos de campo foram concentrados na metade superior do segmento estudado, no trecho situado a montante da ilha dos Bandeirantes; as informações obtidas originaram-se de descrição de afloramentos, de sondagens a trado e a \"vibro-core\", e de perfis de sondagens fornecidos pela CESP e DALCON. Os dados foram analisados por meio de perfis topográficos, geológicos e estratigráficos, dispostos em posição perpendicular e longitudinal em relação ao traçado do rio. Os depósitos estudados ocorrem em diferentes níveis de terraço e nacalha fluvial. O terraço alto e constituído por níveis seixosos da sequencia fluvial SFa, depositada por canais entrelaçados do tipo Scott, e por camada de areia maciça da sequencia coluvial SCa. O terraço médio é constituído por níveis seixosos da sequencia fluvial SFb, depositados por canais entrelaçados do tipo Donjek; e por camada de areia maciça com \"ponds\" argilosos da sequencia coluvial SCb. O terraço baixo é constituído por corpos de areia de forma acanalada ou tabular, da sequencia fluvial SFc, depositados por canais entrelaçados do tipo Platte. A planície fluvial corresponde ao terraço mais próximo do nível do rio, e compreende uma sucessão de depósitos seixosos, arenosos e argilo-arenosos; esses sedimentos compreendem parte da sequencia fluvial SFd, e foram depositados respectivamente por canais entrelaçados do tipo Donjek, do tipo Platte e por canais anastomosados. O terraço médio o baixo e a planície encontram-se parcialmente cobertos por depósitos coluvio-aluviais da sequencia SCc. Os depósitos ativos são constituídos por areia fina á média, acumulados no leito ou sob forma de barras transversais; tais corpos podem no centro do canal, na sua margem, na parte frontal de ilhas, ou fazendo a ligação entre ilhas e/ou as margens do rio. As características hidrológicas do rio Paraná e de seus depósitos ativos permitem compará-los aos canais entrelaçados do tipo South Saskatchewan. A evolução sedimentar dos depósitos ocorreu por meio da alternância de climas úmidos e de climas secos, quando se desenvolveram respectivamente as sequencias fluviais e as coluviais. Durante esse período de tempo esteve ativa uma tectônica que promoveu basculamento e movimentação diferencial entre blocos estruturais, definidos por meio de critérios geomorfológicos limitam os depósitos ao Pleistoceno e Holoceno, e uma correlação com depósitos do rio Tibagi (PR) permite que a sedimentação tenha-se iniciado pelo menos no Plioceno.This research deals with geological mapping and stratigraphy of the Parana river deposits on the reach between Porto Primavera (MS) and Guaira (PR). The geological mapping was based on MSS and RADAR image interpretation and aerial-photo analysis, besides field work in which outcrops and cores were analysed. Field work had been concentrated in the area between Porto Rico and Porto Camargo (PR). Additional data have been supplied by well records from CESP (Porto Primavera) and DALCON (Porto Camargo). The available data were analysed through longitudinal and transversal topographic profiles and geological and stratigraphic crossections. The studied deposits occur in four different levels of terraces and in the active channel. The \"high terrace\" is constituted of gravel deposits of braided channel of Scott type (fluvial sequence SFa) covered with massive sands of colluvial sequence SCa. The \"medium terrace\" is constituted of gravel deposits of braided channel of Donjek Type (fluvial sequence SFb) covered with massive sands and mud ponds of colluvial sequence SCb. The \"low terrace\" is constituted of channel shape and tabular sand bed forms deposited by braided channel of Platte type. The fluvial plain is the lowest terrace and contains pebble deposits of Donjek braided channels covered with sand bed forms deposited by Platte braided channels which have been covered by mud and sand deposited in flood plain, channel and natural levee of anastomosed fluvial system. All the terraces may show alluvial fan and colluvial deposits covering parts of their surface (colluvial bars and lag deposits distributes in two levels into the channel). The hydrologic and faciologic present day characteristic of Parana river enable us to compare them South SasKatchewan braided river. The sedimentary deposits have developed through cyclic climatic changes (humid and dry phases) and under tectonic influence. Active than the alluvial systems. On the other hand, in dry periods the situation was reverted. Tectonic events have tilted the block confined by fault strutures and controlling the valley slope. According to geomorphological correlations the deposits are Quaternary in age, but palinological evidence suggests Pliocene age for the oldest deposits.

Texto completo da fonteResumo:
AbstractWith the increasing demand for infrastructure construction as the global economy progresses, the need for exploration and utilization of deep underground space becomes more crucial. Microseismic (MS) monitoring technology has been widely used in deep underground tunnel projects for safety monitoring in China in recent years. In this paper, four aspects of MS monitoring technology developments, i.e. distribution of projects, environment and system characteristic, purpose, and effect of MS monitoring in deep tunnel projects in China were analyzed and summarized. The results show that the technology was mainly applied in the west of China with a wide range of project types. The maximum buried depth of the tunnels monitored reached 2525 m. The tunnel construction method was mainly drilling and blasting method. The lithologies of the tunnels were mainly marble, granite and basalt. The monitoring purpose was for disaster warning and mechanism understanding. In addition, the future development of MS monitoring technology in deep tunnels in China is prospected. The results will be helpful for a rapid development of MS monitoring technology in deep tunnels in China.

AbstractMagnetic resonance imaging (MRI) has quickly established itself as the reference imaging tool for the management of patients suffering from multiple sclerosis (MS), both for the diagnosis and the follow-up of the evolution and evaluation of the impact of new therapies.The treatment of multiple sclerosis does not cure the disease, but it slows its progression and can help to space out attacks. In this paper, tumor segmentation is treated as a problem of classification using the Ant Colony optimization algorithm (ACO) combined with a proposed protocol based on BrainSeg3D tools. Many studies and many existing approaches tend the multiple sclerosis (MS) which is a chronic inflammatory anomaly of the central nervous system.The aim of this work is to evaluate and to verify the effectiveness of the proposed protocol on a public longitudinal database which contains 20 MS patients. This study is concerned with comparing these results against the ground truth performed by two experts and against other methods namely Dissimilarity Map (DM) creation and segmentation in terms of Dice Similarity Coefficient (DSC).

Texto completo da fonteResumo:
AbstractWe assessed the execution of European Regional Development Funds (ERDF) allocated to promote a Low-carbon economy (LCE) in 23 EU Member States (MS). Each MS is evaluated using the Value-Based Data Envelopment Analysis (VBDEA) method. In the first stage, the efficient MS were identified, and the major reasons that might affect the efficient performance of the ERDF. From the results obtained, 43% of the MS were deemed efficient in the application of ERDF committed to fostering an LCE, and these results were mostly justified by their financial spending rate. At the second stage of the analysis, the changes that needed to be done by inefficient MS to “try and replicate” their efficient counterparts were computed. Furthermore, from the robustness assessment conducted it was possible to show that with thresholds of δ = 5% and δ = 10%, 22% of the MS managed to attain a robust efficiency. While Spain is the leading country in terms of robustness efficiency, Romania (robustly inefficient for δ = 5%), Hungary, and the Czech Republic (the worst in the ranking of inefficient MS) could not apply these funds properly. Given this information, the EU should continue to push policies that secure financial opportunities from engaging in LCE, particularly for MS with limited financial capacities, while still supplying them with improved funding mechanisms and technical expertise.

AbstractMultiple sclerosis (MS) is the most important inflammatory demyelinating disorder that affects both the brain and spine. Dissemination in space and time on MRI is not limited to MS and can occur in neuromyelitis optica spectrum disorder (NMOSD) with aquaporin 4 antibodies, myelin oligodendrocyte glycoprotein-related antibody disease (MOGAD), and a series of other (inflammatory) demyelinating disorders. Spinal cord imaging is an important element of MS (differential) diagnosis and especially relevant in case of possible age-related vasculo-ischemic brain white matter lesions; a negative scan will help to rule out MS. Increasingly, MRI is used to monitor treatment and their complications such as progressive multifocal leukoencephalopathy (PML).

Texto completo da fonteResumo:
Abstract Transported and geologically stored CO2 contains several impurities that depend on its source and associated capture technology. Impurities in anthropogenic CO2 can have damaging impacts on the different elements of a CCS system, which must be considered when developing a CO2 specification (Table 1). Thus, characterising all the impurities and determining the required purity of the CO2 mixture is critically important for the safe design and operation of CCS transport and storage systems. It is important to note that CO2 specifications relate to normal operations. Short-term excursions outside of the recommended maximum concentrations for each impurity may be permissible provided they do not lead to health and safety risks and / or risks to the mechanical integrity of the asset.

Texto completo da fonteResumo:
Abstract The paper considers issues of determining the direction of filtration for oil deposits by means of complex study of the geochemical composition of formation fluids and the dynamics of bottomhole pressure and flow rates, and further use of this information in geological and reservoir simulation models. This integrated technology is not expensive and makes it possible to identify geological uncertainties in the reservoir for intelligent management of development processes, such as waterflooding optimization, reservoir simulation models improvement, water cut source definition, etc. Improving the reliability of information about the reservoir and the presented fluids is undoubtedly relevant and significant task. To solve this problem, fluid samples were taken and complex studies of the composition of the produced water was carried out, including the determination of hydrogen and oxygen isotopes and element composition. The authors note that the isotopic composition of formation waters for a number of wells differs from the analogical parameters for injected water, which is probably associated with the area of uneven reservoir distribution and the existence of a stagnant undrained zone. The result of the calculations is an estimate of the impact coefficient of the injected water on the water composition in the surrounding producer wells. In addition to this, the work included the analysis of the dynamics of fluid flow rate, oil flow rate, bottomhole and reservoir pressures, the influence of injection on the pressure in the drainage area of producer wells. Basing on the results obtained the recommendations were given for changing the injection patterns as it is noted that a number of wells are not affected by injection. Recommendations have been developed for carrying out workovers in order to prevent a decrease in pressure and an increase in oil production.

Texto completo da fonteResumo:
Abstract The objective of this paper is to demonstrate and discuss the implementation of an automated workflow that calculates and manages the Operating Limits of Oil and Gas wells, particularly HPHT. The workflow is primarily based on representative well data and equipment inventory. It runs reliable engineering calculations (including tubular triaxial stress and sensitivity analyses) to define the well operating envelopes. It is aimed to 1) maximize the operating envelopes of well tubulars and downhole packers -compared to other conventional methods- and 2) prevent costly failures of critical well barrier elements (WBE). Results of this automation were encouraging. 100s of SME time hours are saved. Reliable and consistent analysis are performed for MAASP/MAWOP and overall well Operating Envelopes. Millions of dollars are saved by preventing potential and costly unnoticed tubular and/or downhole packer failures that could have been prevented. HSE/ESG is better served. Furthermore, this paper initiates a discussion to review implementation and compare feasibility industry applied methods that calculate wells’ operating envelopes. Important Note: All well data, engineering analysis, operating limits and well information etc., displayed or referred to in this publication, are not necessarily actual and only used for illustration purposes.

Texto completo da fonteResumo:
Abstract Most waterfloods in California target sandstone formations that are unconsolidated in nature with high porosities and high permeabilities. These formations are also characterized by high Poisson ratios and low values of Young's Moduli. There has been a concern if, during the waterfloods of these types of formations, fracturing takes place at high-injection gradients. The influence of various factors on leak-off is studied in detail, indicating that with an increase in rock permeability, the leak-off velocity increases. This study included a comprehensive analysis of the characteristics of such soft formations and their responses to high injection gradients. We show that if the leak-off factors are adjusted to reflect high permeability and proper geomechanical properties, the probability of fracture formation is nil at injection gradients up to 0.9 psi/ft, for unconsolidated rooks. We computed estimated fracture width, fracture height, fracture length and noted for all three calculations, it takes gradients approaching 1psi/ft to note a non-trivial estimated value for these characteristics. This study shows that for unconsolidated formations like those in California targeted for waterfloods, the probability of fracture formation under pressure gradients of 0.9 psi/ft. is nil, and high injectivities can be exercised without the fear of fracture formation.

Abstract To explore the opportunity for maximum utilization for a Sales Gas Compression Facility (SGCF) in line with ADNOC strategy to enhance profitability and asset utilization. A technical study was conducted to increase the processing capacity up to 133% of its design limit by utilizing the available design margins. This was to identify the potential bottlenecks in the facility and suggest debottlenecking options (if bottlenecks are there). The Technical study covered the following activities: Simulation: Process simulation was performed and H&MB (Heat and Material Balance) was generatd. Engineering: Compressor adequacy checks on increased plant throughputs. Static Equipment rating and adequacy checks performed with the concurrence of original equipment menufacturerers. Line sizing adequacy checks and detailed evaluation of the piping. Adequacy check for In-line instruments like control valves, flow elements/transmitters (Note 1) Relief, blowdown and flare system adequacy check. Utilities adequacy checks. Risk assessment workshop was conducted before the capacity test run. Preparation of Test Run procedure before the actual test run. Actual plant capacity test run to verify the study findings. Note 1: Adequacy check of thermowells had been peformed separately prior to the study. It had already been established that the thermowells were adequate for the increased plant throughputs. The study has concluded the following observations for processing 133% of the design capacity Theoratically, the Sales Gas Compression Plant is adequate to handle the sales gas throughput up to 600 MMSCFD (2 running machines) considering the facts that Sales Gas Compressor suction pressure must always be kept at 32 barg through close monitoring by the operaters.If compressor suction pressure starts dropping below 32 barg, the study outcome would no more valid and the plant throughput would be reduced back to the original design capacity of 450 MMSCFD. Moreover, it was recommended to perform a field test run to validate the study outcome by following the Manageement of Change Procedure as applicable. Based on the successful 48 hours test run, it was established that the facility could handle the increased plant throughput of 600 MMSCFD by following the instructions given in the adequacy study.

Abstract Gravity settling represents the main oil-water separation mechanism. Many separation plants rely only on gravity settling with the aid of demulsifiers (direct or reverse breakers) and others chemicals such as water clarifiers if they are required. Yet, other complementary separation methods exist including filtration, flotation, and centrifugation. In terms of results and more specifically with respect to the separated produced-water, the main threshold on its quality is the dispersed oil content. Even with zero discharge and reinjection into hydrocarbon formations, the presence of residual oil in the aqueous phase represents a concern. High oil content results into formation damage and losses in injectivity which necessitates formation stimulations and hence additional operational expenses. In this work, we investigated the effects of different separation techniques on separated water quality. Based on the results, we identified potential improvements to the existing separation process. We used synthetic well-characterized emulsions. The emulsions were prepared at the forecast water:oil ratio using dead crude oil and synthetic representative brine. To clearly delineate and distinguish the effectiveness of different separation methods, we exacerbated the conditions by preparing very tight emulsions compared with what is observed on site. With that, we investigated three separation techniques: gravity settling, centrifugation, and filtration. First, we used jar tests to study gravity settling, then a benchtop centrifuge at two speeds to evaluate centrifugation potential. Finally, for filtration, we tested two options: membrane and deep-bed filtrations. Concerning the water quality, we performed solvent extraction followed by UV analyses to measure the residual oil content as well as light transmission measurements in order to compare the efficiency of different separation methods. The results of analyses suggest that gravity settling was not efficient in removing oil droplets from water. No separation occurred after 20 minutes in every tested condition. However, note that investigated conditions were severe, tighter emulsions are more difficult to separate compared to those currently observed in the actual separation plant. On the other hand, centrifugation significantly improved light transmission through the separated water. Accordingly, we can conclude that the water quality was largely improved by centrifugation. In terms of filtration, very good water quality was obtained after membrane filtration. However, significant fouling was observed. With deep-bed filtration, produced water quality remained good and fouling was no longer observed. On the basis of those results, we conclude that for our case study, centrifugation and deep-bed filtration techniques can significantly improve quality of the separated and eventually reinjected water. Thereby, integration of any of the two methods in the separation plant will lead to more efficient produced-water reinjection, eliminating formation damage and frequent stimulations. Yet, it is important to note that economics should be further assessed.

Johra, Hicham. Simple uncertainty budget and assessment with the Kragten method: Examples for building physics. Department of the Built Environment, 2024. http://dx.doi.org/10.54337/aau633631860.
Texto completo da fonteResumo:
The aim of this lecture note is to present and exemplify the Kragten method to calculate the combined uncertainty (uncertainty budget) of a measurand from the standard uncertainty estimates of individual inputs of that measurand, and the mathematical formulation of that measurand. If these two elements are not available, the Kragten method cannot be applied. The method also provides sensitivity (significance) assessment of the different components (inputs) in the combined uncertainty budget. The Kragten method for uncertainty calculation is very simple yet a robust and accurate alternative to the more complex GUM or Monte Carlo simulation methods. It can be performed with a simple spreadsheet tool (e.g., MS Excel) with minimum risks of mistakes. This method is adequate for the field of building physics, energy in buildings and indoor environmental engineering. This lecture note also provides examples of uncertainty calculations (budgets) for common measurands and metrics in the field of building physics, energy in buildings and indoor environmental engineering. These examples are attached to the present lecture note document (Excel spreadsheet documents). One should note that this lecture note does not cover the process of estimating the standard uncertainty of the individual inputs of the measurand. Those standard uncertainties should be obtained from technical documentation, models, or estimates from measurements (e.g., 1σ standard deviation of a set of repeated measurements on measurand that is assumed to remain constant over the monitoring period), and converted into standard uncertainties (1σ confidence interval assuming a normal probability distribution or the errors).

Gandini, Camilla, Andrea Monje Silva e Pablo Guerrero. Gender and Transport in Haiti: Gender Diagnostic and Gender Action Plan. Editado por Amanda Beaujon Marin. Inter-American Development Bank, fevereiro de 2021. http://dx.doi.org/10.18235/0003069.
Texto completo da fonteResumo:
This technical note encompasses Haiti's gender assessment, evaluates the success of gender specific actions implemented between 2011-2017, and presents a Gender and Transport Action Plan (GAP). The GAPs main aim is to guide investments in Haiti's transport sector in conceptualizing and designing gender-sensitive transport projects. By proposing specific gender actions and outcomes, the GAP establishes a clear path to integrate a gender dimension into operations design, implementation and, monitoring and evaluation. The GAP presents an overall plan to support the development of Haitian women. However, it focuses in the needs of women as transport services users and devotes specific attention to two female sub-groups, comprised by Haitian women engaged in informal trade of local and regional products. These women are known as Madan Sara (MS), and local female mango producers and traders (MPT). The decision of focusing on MS is related to their vital role in the Haitian local labor market and the peculiarity of their work, which has specific transport needs. Understanding and addressing these female groups transport constrains could strategically improve the outcomes of upcoming transport investments and bring more benefits to its beneficiaries.

Dunbar, Joseph. Vertical and horizontal datums used in the Lower Mississippi Valley for US Army Corps of Engineers projects. Engineer Research and Development Center (U.S.), janeiro de 2022. http://dx.doi.org/10.21079/11681/42781.
Texto completo da fonteResumo:
Six geodetic datums have been used by the US Army Corps of Engineers (USACE), Mississippi River Commission (MRC), for river surveys in the Lower Mississippi Valley (LMV). These legacy elevation datums are the Cairo datum, the Memphis datum, the Mean Gulf Level (MGL), the Mean Sea Level (MSL), the National Geodetic Vertical Datum (NGVD) 1929, and the North American Vertical Datum 1988 (NAVD88). The official geodetic datum currently prescribed by the USACE is NAVD88 (USACE 2010). In addition to these different geodetic datums, hydraulic datums are in use by the USACE for rivers, lakes, and reservoir systems. Hydrographic surveys from the Mississippi River are typically based on a low water pool or discharge reference, such as a low water reference plane (LWRP), an average low water plane (ALWP), or a low water (LW) plane. The following technical note is intended to provide background information about legacy datums used in the LMV to permit comparison of historic maps, charts, and surveys pertaining to the Mississippi River in the LMV. The purpose of this report is to provide background information and history of different published horizontal and vertical datums used for presentation of hydrographic survey data from the Mississippi River. The goal is to facilitate understanding of differences with comparison to other historic surveys for change-detection studies along the river. Conversion values are identified herein for the earlier surveys where appropriate, and methods are presented here to evaluate the differences between earlier and later charts and maps. This report is solely intended to address the LMV area and historic surveys made there. This note is not applicable to areas outside of the LMV. Throughout this technical note, historic hydrographic surveys and data from the Memphis, TN, to Rosedale, MS, reach will be used as examples of features of interest for discussion purposes. Selected historic hydrographic survey sheets at Helena, AR, are included as Plates 1 to 3 (Appendix C) of this document and will be used as examples for discussion purposes.

Abdolmaleki, Kourosh. PR-453-134504-R05 On Bottom Stability Upgrade - MS III. Chantilly, Virginia: Pipeline Research Council International, Inc. (PRCI), novembro de 2021. http://dx.doi.org/10.55274/r0012195.
Texto completo da fonteResumo:
The extension of the PRCI on bottom stability (OBS) software's applicability to shallow water is assessed. Version 3 of the software has a limitation on water depth; only depths greater than 6 m (20 ft) are accepted. This limitation is likely related to the increasing inaccuracy of linear wave theory as the wave height to water depth ratio increases, as well as caution about breaking wave limits. The usage of linear wave theory inside the software can be categorized into two different types: � Linear regular waves - these are used in the Level 1 module to determine the motions of the water particles as part of the calculation of the hydrodynamic forces; � Linear irregular waves - these are present in the Level 2, Level 3 and ASM modules, where the surface wave energy spectra are converted to the near-seabed wave velocities through the use of a transfer function based on linear wave theory. It is noted that for irregular waves, all wave spectral formulations currently implemented in the OBS software, do not account for water depth. This document addresses the finite water depth and shallow water restrictions and presents a discussion and investigation in two categories: 1. The direct use of the linear theory to describe waves in the Level 1 calculation module; and 2. The direct use of linear spectral transfer functions in the Level 2, Level 3, and ASM modules. The scope of this activity is to prepare a solution for consideration by PRCI and implement the agreed course of action. The solution proposed will be based on the continued use of the linear wave theory. It is noted that higher order wave theories would be more appropriate for shallow water conditions, but due to the currently established methodology in the software, implementation of higher order wave theory is not included within this scope.

Texto completo da fonteResumo:
The “shrimp mushroom”, Russula xerampelina, has a strong cooked shellfish odour. Headspace volatiles from fresh sporocarps of this mushroom were analysed using solid phase microextraction (SPME) and gas chromatography–mass spectrometry (GC–MS). Trimethylamine and trimethylamine N-oxide were the only volatile compounds detected emanating from the fruiting body. Trime- thylamine is noted for its fishy, cooked crab or cooked shrimp-like odour.

Texto completo da fonteResumo:
The overall theme of this project was to increase the speed of analysis for monitoring pesticide residues in food. Traditionally, analytical methods for multiple pesticides are time-consuming, expensive, laborious, wasteful, and ineffective to meet critical needs related to food safety. Faster and better methods were needed to provide more cost-effective detection of chemical contaminants, and thus provide a variety of benefits to agriculture. This overarching goal to speed and improve pesticide analysis was successfully accomplished even beyond what was originally proposed by the investigators in 1998. At that time, the main objectives of this project were: 1) to further develop a direct sample introduction (DSI) device that enables fast sampling and introduction of blended-only agricultural products for analysis by gas chromatography (GC); 2) to evaluate, establish, and further develop the method of simultaneous pulsed flame photometric detector (PFPD) and mass spectrometry (MS) detection for enhanced pesticide identification capabilities; and 3) to develop a new and novel MS pesticide analysis method, based on the use of supersonic molecular beams (SMB) for sampling and ionization. The first and third objectives were successfully accomplished as proposed, and the feasibility of the second objective was already demonstrated. The capabilities of the GC/SMB-MS approach alone were so useful for pesticide analysis that the simultaneous use of a PFPD was considered superfluous. Instead, the PFPD was investigated in combination with an electron-capture detector for low-cost, simultaneous analysis of organophosphorus and organochlorine pesticides in fatty foods. Three important, novel research projects not originally described in the proposal were also accomplished: 1) development of the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for pesticides in foods; 2) development and optimization of a method using low-pressure (LP) GC/MS to speed pesticide residue analysis; and 3) innovative application of analyte protectants to improve the GC analysis of important problematic pesticides. All of the accomplishments from this project are expected to have strong impact to the analytical community and implications to agriculture and food safety. For one, an automated DSI approach has become commercially available in combination with GC/MS for the analysis of pesticide residues. Meanwhile, the PFPD has become the selective detector of choice for the analysis of organophosphorus pesticides. Great strides were made in SMB-MS through the manufacture of a prototype "Supersonic GC/MS" instrument, which displayed many advantages over commercial GC/MS instruments. Most notably, the QuEChERS method is already being disseminated to routine monitoring labs and has shown great promise to improve pesticide analytical capabilities and increase lab productivity. The implications of these developments to agriculture will be to increase the percentage of food monitored and the scope of residues detected in the food, which will serve to improve food safety. Developed and developing countries alike will be able to use these methods to lower costs and improve results, thus imported/exported food products will have better quality without affecting price or availability. This will help increase trade between nations and mitigate certain disputes over residue levels in imported foods. The improved enforcement of permissible residue levels provided by these methods will have the effect to promote good agricultural practices among previously obstinate farmers who felt no repercussions from illegal or harmful practices. Furthermore, the methods developed can be used in the field to analyze samples quickly and effectively, or to screen for high levels of dangerous chemicals that may intentionally or accidentally appear in the food supply.

May, David, David Biedenharn, Tate McAlpin e Ty Wamsley. Hydraulic dike effects investigation on the Mississippi River : Natchez to Baton Rouge. Engineer Research and Development Center (U.S.), maio de 2021. http://dx.doi.org/10.21079/11681/40539.
Texto completo da fonteResumo:
This report documents an investigation of the hydraulic effects of dikes on water levels in the Mississippi River between Natchez, MS, and Baton Rouge, LA, conducted for the U.S. Army Corps of Engineers, Mississippi Valley Division, Vicksburg, MS. The investigation was conducted using a previously calibrated Natchez-to-Baton Rouge Adaptive Hydraulics numerical model. The objectives were to alter roughness and height variables associated with the dikes and overbanks encompassed in the numerical model and evaluate their effects on water surface elevations. This academic exercise provides an indication of the relative level of impact associated with modifications to the dikes and overbanks for this portion of the Mississippi River and does not represent future plans or recommendations by the U.S. Army Corps of Engineers. Steady flow simulations were simulated for 12 May 2011 to investigate the variation in model results during the peak of the 2011 flood on the Mississippi River.

Texto completo da fonteResumo:
The Geological Survey of Canada undertook a mineral resource assessment for a proposed national park in northern Canada (~ 33,500 km2) spanning the transition from boreal forest to barren lands tundra. Bedrock geology of this region is complex and includes the Archean Slave Craton, the Archean and Paleoproterozoic Rae domain of the Churchill Province, the Paleoproterozoic Thelon and Taltson magmatic-tectonic zones, and the Paleoproterozoic East Arm sedimentary basin. The area has variable mineral potential for lode gold, kimberlite-hosted diamonds, VMS, vein uranium and copper, SEDEX, as well as other deposit types. A comparison of analytical methods was carried out after processing the field collected samples to acquire both the < 2 mm and for the < 0.063 mm size fractions for 241 surficial sediment (till) samples, collected using a 10 x 10 km grid. Analytical methods comprised: 1) aqua regia followed by ICP-MS analysis, 2) 4-acid hot dissolution followed by ICP-ES/MS analysis, 3) lithium metaborate/tetraborate fusion methods followed by ICP-ES for major elements and ICP-MS for trace elements and, 4) portable XRF on dried, non-sieved sediment samples subjected to a granular segregation processing technique (to produce a clay-silt proxy) for seventeen elements (Ba, Ca, Cr, Cu, Fe, K, Mn, Ni, Pb, Rb, Sr, Th, Ti, U, V, Zn, and Zr) Results indicate that pXRF data do not replicate exactly the laboratory 4-acid and fusion data (in terms of precision and accuracy), but the relationship between the datasets is systematic as displayed in x-y scattergrams. Interpolated single element plots indicate that till samples with anomalies of high and low pXRF concentration levels are synonymous with high and low laboratory-based analytical concentration levels, respectively. The pXRF interpolations thus illustrate the regional geochemical trends, and most importantly, the significant geochemical anomalies in the surficial samples. These results indicate that pXRF spectrometry for a subset of elements is comparable to traditional laboratory methods. pXRF spectrometry also provides the benefit of rapid analysis and data acquisition that has a direct influence on real time sampling designs. This information facilitates efficient and cost-effective field projects (i.e. where used to identify regions of interest for high density sampling), and to prioritize samples to be analyzed using traditional geochemical methods. These tactics should increase the efficiency and success of a mineral exploration and/or environmental sampling programs.

Geochemical evidence for a magmatic contribution to the metal budget of the Windy Craggy Cu-Co(±Zn) volcanogenic massive-sulfide deposit, northwestern British Columbia. Natural Resources Canada/CMSS/Information Management, 2022. http://dx.doi.org/10.4095/328018.
Texto completo da fonteResumo:
Volcanogenic massive-sulfide (VMS) deposits may have had metal contributions from magmatic degassing and leaching of footwall rocks. The Windy Craggy Cu-Co-Zn VMS deposit in northwestern British Columbia may include magmatic contributions, based on laser-ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) of fluid inclusions (enriched in Sb, Sn, and Bi) and lithogeochemistry. Sulfide-mineral trace-element abundances in the massive-sulfide orebody, underlying stockwork zone, gold zone, and altered and unaltered mafic rock and argillite were analyzed by LA-ICP-MS. Elevated Au, W, As, Bi, Sb, Se, Te, Tl, Ag, Co, and Mo contents occur within the gold and/or stockwork zones. Increasing 'magmatic metals' with increasing Co/Ni values suggest direct magmatic contribution to the deposit. Covariation of Co with these so-called 'magmatic elements' indicates that it, too, may be of magmatic origin, sourced via fluids exsolved from a crystallizing magma; however, evidence from the composition of rocks and sulfide minerals from Windy Craggy and other VMS deposits suggests that there is probably no meaningful distinction between hydrothermal leaching and direct magmatic contributions and that most - if not all - fluids that form VMS deposits should be termed 'magmatic-hydrothermal'.

Texto completo da fonteResumo:
Les granites peralumineux sont reconnus à l'échelle mondiale comme le produit magmatique final des cratons archéens. Cependant, leur durée, les conditions thermiques de leur mise en place, leur séquence de cristallisation, ainsi que les liens avec l'évolution tectonométamorphique des roches encaissantes et les systèmes minéralisés en métaux précieux, de base, et rares sont peu connus. Le Batholite de Decelles (c. 2670-2620 Ma) exposé dans le sud-est du craton du Supérieur au Québec, Canada est l'un des plus volumineux de la région, offrant une opportunité unique dmp;gt;'améliorer notre compréhension des conditions thermiques et de la mobilité des magmas et des fluides dans la croûte moyenne et supérieure. Nous présentons des nouvelles datations Lu-Hf et des cartes dmp;gt;'éléments traces sur grenat de trois échantillons de granite du Batholite de Decelles. Les nouvelles dates de 2668 ± 4 Ma, 2663 ± 5 Ma, 2656 ± 7 Ma sont indifférenciables (considérant les incertitudes) des dates Lu-Hf sur grenat et U-Pb sur monazite des unités métasédimentaires encaissantes. La cartographie des éléments traces in situ par LA-ICP-MS révèle une zonation compositionnelle systématique. Les grenats présentent un cur avec une zonation oscillatoire concentrique en Li, P, Sc, Ti, Y, Zr, REE, Hf, Th et U; et une surcroissance marquée par des concentrations relativement élevées en MREE, HREE et V, et de faibles concentrations en Li, Ti, P, Sm, Zr, Hf et U par rapport aux curs. Les résultats indiquent une origine magmatique des grenats par opposition aux grenats métamorphiques de la source avec une histoire de cristallisation complexe. Le contenu en éléments traces du grenat semble être contrôlé par des variations cinétiques de croissance et de diffusion à l'interface grenat-matrice, ainsi que par la cristallisation de phases majeures et accessoires telles que la muscovite, la monazite, l'apatite et le zircon. Dans l'ensemble, le grenat du Batholite de Decelles date le début de la cristallisation magmatique et son contenu en éléments traces enregistre son histoire complète. Les archives géochronologiques régionales indiquent une évolution commune des niveaux de croûte moyenne et supérieure avec un refroidissement progressif entre c. 2640 et c. 2620 Ma, associé à la migration et au refroidissement de fluides minéralisateurs.
