AbstractStudy of the synergistic inhibition properties of the combined admixture of 4-methyl-norvalin and 2-methoxy-4-formylphenol (non-toxic organic compounds) on the corrosion of P4 low carbon mold steel in 1.5 M H2SO4 and HCl solution was performed with weight loss measurement, potentiodynamic polarization and optical microscopy analysis. Results obtained showed the inhibition efficiency of the admixed compound performed above the value for effective corrosion inhibition at very low concentrations in H2SO4 solution. However, from mid concentration to the highest concentration studied, the inhibition efficiency of the compound was above 85% from electrochemical tests. In HCl solution the inhibition efficiency of the compound was well above 80% and 90% for weight loss and polarization tests at all concentration studied. Anodic corrosion inhibition mechanism was determined for the compound in H2SO4 according to Freundlich and Frumkin adsorption isotherms due to weak Van der Waals attraction between the inhibitor molecules and the steel’s surface. The mechanism of corrosion inhibition in HCl was calculated to be cathodic type according to Langmuir isotherm model.Morphological images of inhibited and non-inhibited steel surfaces significantly contrast each other though the extent of deterioration was much severe for the steel from H2SO4 solution.

AbstractThe challenge related to waste management has become a serious worldwide environmental problem. Highly sustainable solutions, which do not involve reworking the material and are based on waste utilization, are sought. Such waste as used casting compounds, which so far has been used, among others, in construction, road construction, mining and cement production. Descriptions of the use of various waste moulding compounds, such as waste quartz compounds with water glass, quartz chamotte and quartz bentonite can be found in the literature. Due to the high content of quartz and low toxicity of bentonite sandmix, an attempt was done to use them for the production of sand-lime products.The aim of this article is to determine the suitability of the waste material as a substitute for quartz sand in the production of sand-lime products. The usability of waste was determined by laboratory tests of physicochemical characteristics of the finished silicates. Sand, which is a carrier of silica, was replaced with used moulding compounds with fractions up to 0.5 mm, in the weight amounts of 5.5, 11 and 16.5%. Applying up to 11% of used casting materials as a substitute for quartz sand with a lime content of 5.5% in the raw material mixture has a clearly positive effect on compressive strength. However, the higher share of sand substitution in the mixture weakens the mechanical features of the obtained materials. The absorptivity of the finished products increases with the increase of the inserted additions’ amounts. The influence of significant amounts of casting compound additives on the microstructure of calcium-silicate products was studied as well. It was stated, that they affect the location of the tobermorite in the volume of the autoclaved material.

Full textAbstract:
N-Nitrosodimethylamine (NDMA) is a highly hepatotoxic compound and classified as group 2A according to IARC, which is probably carcinogenic to humans. The habit of consumption of grilled meat-based foods may lead to a health risk, especially in children. In this study, a food consumption survey was conducted in 4 districts (2 in urban and 2 in suburban areas) in Hanoi, Vietnam. Food samples in the diet of children from 6 to 36 months was collected and tested for NDMA by GC-MS/MS method. Total exposure dose was calculated and compared to the proposed tolerable daily intake (TDI) to characterize the risk. Among the food tested, NDMA was detected in canned puree, grilled meat and sausage. The average contents of NDMA were 1.50 μg/kg, 1.18 μg/kg and 0.20 μg/kg in grilled meat, sausage and puree, respectively. The average total daily exposure dose of NDMA was 8.23 ng/kg bw/day in all studied group, which were within the upper recommended TDI (9.3 ng/kg bw/day). With a certain assumption, the cancer risk caused by exposure to NDMA were higher than the recommended value of WHO.

This study concentrates on compound pronouns in English and Albanian. Compounding is considered as one of the most prolific word formation techniques in both languages. The study is made up of three basic parts: compounding is analysed theoretically; compound pronouns collected by the Dictionary of Contemporary Albanian Language and Oxford Student’s Dictionary are analysed; conclusions are drawn as of their similarities and differences. Albanian language provides interesting results as it includes a specific category of pronouns under a different heading than compounding and that is agglutinated pronouns. Compound pronouns are analysed quantitatively and qualitatively in both languages. Quantitative analysis deals with their positioning in relation to all compound words per each dictionary. Qualitative analysis deals with the elements constituting the compound pronouns. The study also pinpoints the differences and similarities between compound pronouns when translated from English into Albanian and vice versa. The study is illustrated with abundant examples in both languages. Statistic results of the study show that Albanian compound (agglutinated) pronouns outnumber the English compound pronouns→ 81: 18; also constituent structures of Alb. vs Eng. pronouns are →9:2. Translation of pronouns from one language into the other: one English pronoun – different Albanian pronouns and vice versa.

Abstract In order to better reflect the actual ecological performance of vehicles in traffic conditions, both the emission standards and the applied emission tests are being developed, for example by considering exhaust emissions for a cold engine start. This article presents the research results on the impact of ambient temperature during the cold start of a gasoline engine in road emission tests. The Real Driving Emissions (RDE) tests apply to passenger cars that meet the Euro 6 emissions norm and they are complementary to their type approval tests. A portable emissions measurement system was used to record the engine and vehicle operating parameters, as well as to measure the exhaust emissions during tests. This allowed for parameters such as engine load, engine speed and vehicle speed to be monitored. The cold start conditions for two different temperatures (8°C and 25°C) were compared in detail. Moreover, the engine operating parameters, exhaust concentration values and road emissions for the 300 s time interval, were compared. The summary of the article presents the share of a passenger car’s cold start phase for each exhaust compound in the urban part of the test and in the entire Real Driving Emissions test depending on the ambient temperature.

To determine the variability of the abnormalities found in the electroneurography (ENG) of the facial nerve in cases of Bell's palsy during the initial two week period was one of the objectives of the authors. A second one was to investigate the value of ENG as a tool to determine an early prognosis of recovery utilizing two different methods. In the first one the amplitude of the compound muscular action potential (CMAP) obtained on the paralyzed side was compared to this potential on the opposite (normal) side. The second method compared the CMAP on the paralyzed side to normal standardized data from normal individuals. A group of 33 patients with Bell's palsy was followed until total recovery or for at least 4 months, if the recovery was not achieved earlier. It was observed that amplitude of the CMAP become stable towards the sixth day of palsy and this is a good time to establish the prognosis. Another conclusion is that both methods were equivalent to determine the prognosis in Bell's palsy.

Resumo: O desenvolvimento dos centros urbanos tem conduzido a um aumento desordenado na geração de resíduos e conseqüente poluição ambiental. Tendo em vista o potencial agronômico dos resíduos gerados pelas cidades, o presente trabalho teve por objetivo verificar a influência do composto de lixo (CL), composto de poda de árvore (CP) e substrato comercial (SC), associados a diferentes lâminas de irrigação no desenvolvimento de porta-enxerto (limão-cravo) de citros. O delineamento experimental adotado foi em blocos casualizados em um esquema fatorial 6x3, sendo seis diferentes combinações de substratos: S1 - 100% SC; S2 - 80% SC + 20% CP; S3 - 60% SC + 30% CP + 10% CL; S4 - 40% SC + 40% CP + 20% CL; S5 - 20% SC + 50% CP + 30% CL e S6 - 60% CP + 40% CL associados a três lâminas de irrigação: 50% (I1), 100% (I2) e 150% (I3) da evapotranspiração diária medida pelo atmômetro. Os parâmetros avaliados das plantas foram: altura, número de folhas, diâmetro do caule, matéria fresca aérea e matéria seca aérea. Os resultados permitiram concluir que a irrigação abaixo da evaporação medida pelo atmômetro causaram efeito negativo no desenvolvimento das plantas e que a reposição de água com 150% (I3) foi a que favoreceu o desenvolvimento. Os substratos S2, o qual se utilizou 80% de SC associado à 20% CP foi os que proporcionou melhor desenvolvimento dos porta-enxertos. Os substratos com porcentagem de composto de lixo superior a 30% mostraram-se inadequados para o desenvolvimento dos porta-enxertos
Abstract: The development of urban centers has led to an inordinate increase in the generation of waste and consequent environmental pollution. Considering the agronomic potential of the waste generated by cities, the present work objective was to check the influence of garbage compound (GC), pruning of tree (PT) and commercial substrate (CS), associated to different irrigation blades in the rootstocks (Rangpur Lime) citros development. The experimental delineation adopted was in random blocks in a fatorial scheme 6x3, being six different substrates combinations: S1 - 100% CS; S2 - 80% CS + 20% PT; S3 - 60% CS + 30% PT + 10% GC; S4 - 40% CS + 40% PT + 20% GC; S5 - 20% CS + 50% PT + 30% GC e S6 - 60% PT + 40% GC associated to different irrigation blades: 50% (I1), 100% (I2) e 150% (I3) of the daily evapotranspiration measured by the atmometer. The evaluated plants parameters were: height, leaves number, stem diameter, fresh matter and dry matter of the air part. The results allowed to conclude that the irrigation below the evaporation measured by the atmometer caused negative effect in the plants development and the water replacement with 150 % (I3) was the one that favored the development. The substrates S2, which is used 80% of SC associated with 20% CP was that the enhanced growth of the rootstocks. The substrates with garbage compound percentage superior to 30 % appeared unsuitable for the rootstocks development

Resumo: Em todo processo, é presumível a condição da geração de resíduos, sendo cada vez mais premente a busca de alternativas para destinação correta destes resíduos. Neste sentido, foi realizado um experimento com a compostagem de diferentes resíduos sólidos industriais provenientes do processo de extração do princípio ativo de plantas medicinais. O experimento constitui-se na mistura, em proporções diferentes dos resíduos: a) Resíduo orgânico - gerado a partir do esmagamento da planta de jambú (Spilanthes oleracea), após a extração do princípio ativo, b) lodo físico-químico, gerado a partir do processo de tratamento de água e c) lodo biológico, oriundo do esgoto da empresa. Este trabalho teve como objetivos gerar uma alternativa, ambientalmente correta, para o reaproveitamento do lodo físico-químico e verificar o efeito agronômico dos compostos resultantes na produção da alface. O processo de compostagem deu-se no período de 120 dias. A temperatura das pilhas foi medida diariamente, em três diferentes profundidades. Ao final, o composto foi pesado e avaliou-se, em média, o rendimento. Na segunda fase do experimento, buscando avaliar o efeito agrônomico dos compostos sobre a produção da alface (Lactuca sativa L.), os materiais compostos foram dispostos em vasos, em casa de vegetação, formando um delineamento inteiramente casualizado (DIC), com fatorial 4 x 4, sendo o fator 1 formado por 4 tratamentos: composto 1 (C1 - 0% lodo - 100% jambú), composto 2 (C2 - 7% lodo - 93% jambú), composto 3 (C3 - 13% lodo - 87% jambú), composto 4 (C4 - 26% lodo - 74% jambú) e o fator 2 formado por 4 diferentes doses de compostos: (0, 45, 90 e 135 t ha-¹ ) e quatro repetições, totalizando 64 unidades experimentais.

Abstract: It is assumed that there is generation condition in every production process. Alternative ways for the correct destination of the residues has become essential. Therefore, an experiment on different industrial solid residues compound from medicinal plants active principle extration has been performed. The experiment was based on the mixture of the residues in different proportions: a) organic residue generated from jambu (Spilanthes oleracea) smashing after active principle extraction, b) physiochemic mud generated from water treatment process and c) biologic mud originated from the company sewage. This work aimed at generating an environmentally correct alternative for phisiochemic mud reutilization and verify the agronomic effects of the resulting compounds in lettuce production. The compounding process lasted 120 days. Piles temperature was measured in three different depths. At the end, the compound was weighed and the average yield was evaluated. In the second phase of the experiment we aimed at evaluating the compound agronomic effects on lettuce (Lactuca sativa L.) production. The compounded materials were placed ins vases in greenhouses in an entirely randomized order, with factorial 4 x 4. Factor 1 was formed by 4 treatments: compound 1 (C1 - 0% mud - 100% jambu), compound 2 (C2 - 7% mud - 93% jambu), compound 3 (C3 - 13% mud - 87% jambu), compound 4 (C4 - 26% mud - 74% jambu). Factor 2 was formed by 4 differente compound dosages: (0,45, 90 e 135 t ha-¹) and hour repetitions, totaling 64 experomental unities. Treatment C1, dosage 3 (90 t ha-¹) presented the best results in the evaluation 45 days after lettuce transplantation. In the remaining treatments there was alinear decrease in lettuce production. However, C4 that 26% mud in its composition was superior than those with 0 dosage of organic matter. Compound can be considered an environmentally correct alternative for these residues with the possibility of agronomic utilization.

Resumo: Na produção de hortaliças é fator determinante a adubação aplicada nas dosagens corretas e a reposição de água no solo em quantidades ideais. A adubação com compostos orgânicos pode diminuir o custo da produção e proporcionar aumento da produtividade. O presente trabalho teve como objetivos determinar os efeitos das reposições de água de irrigação na produtividade, e a dosagem do composto de lixo a ser utilizada na cultura do pimentão quando cultivada em ambiente protegido. O experimento foi conduzido em estufa modelo arco com 280 m2. O delineamento experimental foi em blocos casualizados com 24 tratamentos em esquema fatorial de 6 x 4 (formas de adubação e reposição de água no solo, respectivamente). Quanto à adubação, foram seis formas: adubação mineral e adubação com composto de lixo orgânico (4 t ha-1, 8 t ha-1, 12 t ha-1 e 16 t ha-1), mais uma testemunha sem adição de adubos. Quanto às reposições de água no solo foram de 70%, 100%, 130% e 160% da lâmina necessária para elevar o solo à capacidade de campo. Foram determinados o número de frutos, altura das plantas, diâmetro do caule, eficiência do uso da água e a produtividade da cultura. Dentre os resultados, verificou-se que quando a reposição de água no solo foi efetuada integralmente (100% de reposição) a produtividade foi similar entre as adubações com composto de lixo orgânico de 16 t ha-1, 12 t ha-1 e 8 t ha-1
Abstract: In vegetables production, the correct dosages of applied fertilizer and replacement of water in the soil in optimal amounts is a determining factor. The fertilization with organic compounds can decrease the production cost and provide increased productivity. This study aimed to: determine the effects of different replacement of irrigation water in crop yield, and optimal dosage of organic compound to be used in sweet pepper when grown in a greenhouse. The experiment was conducted in a bow model greenhouse with 280 m2. The experiment was designed in randomized blocks with 24 treatments in a factorial arrangement of 6 x 4 (types of fertilization and water replacement in the soil, respectively). As for fertilization, it's used six forms: fertilization with mineral fertilizer and organic compound (4 t ha-1, 8 t ha-1, 12 t ha-1 and 16 t ha-1) and one as control, without addition of fertilizers. For the water replacement in the soil, it's used 70%, 100%, 130% and 160% of the blade to raise the soil at field capacity. It was determined the number of fruits, plants height, stalk diameter, efficiency of water use and crop productivity. Among the results, it was found that when the replacement of water in the soil was made in full (100% replacement) the productivity was similar between the fertilizer with organic waste compound of 16 t ha-1, 12 t ha-1 and 8 t ha-1

Abstract: The need to study the use of waste pruning of trees is of great importance to solve the environmental problems of solid waste in the urban areas along with the waste of household waste. The study of these materials was evaluated with the development of seedlings of yellow-ipe [Tabebuia chrysotricha (Mart. ex DC.) Sandl.] in mixtures of different substrates and types of water for irrigation. The experiment was installed at the Department of Rural Engineering of de São Paulo University State, Campus of Jaboticabal. Two experiments were conducted, evaluated together with experimental design in randomized blocks of 8 substrates, 2 qualities of water and 4 repetitions, totaling 64 parcels. Each parcel was composed of 30 plants (5 rows of 6 plants) and is regarded as useful, the 3 lines of 4 plants of the central plot. Eight substrates were tested, resulting from the combination of commercial substrate, composed of household waste and composed of pruning of trees with 2 types of irrigation water (clean water and residuary) and 4 repetitions. To observe the development of seedlings of yellow-ipe, were evaluated the height of the shoots of plants, diameter of the stem, dry material and leaf analysis. The characteristics were evaluated at 21, 42, 63 and 84 days after the emergency. The analysis of results allowed to conclude that the substrates studied promoted significant differences in average height of the plants, stem diameter, dry material and leaf analysis in all periods of assessment. The interaction between substrate and water for irrigation were to average height and diameter of the plant stem at 42, 63 and 84 days after emergency and in all of leaf analysis nutrients. The substrates 3, 4 and 5 with residuary water showed the best results in the development of seedlings of yellow-ipe.

Luengo, Arratta S. "Intramolecular ene reactions of functionalised nitroso compounds." Thesis, University College London (University of London), 2010. http://discovery.ucl.ac.uk/20237/.
Full textAbstract:
This thesis concerns the generation of geminally functionalised nitroso compounds and their subsequent use in intramolecular ene reactions of types I and II, in order to generate hydroxylamine derivatives which can evolve to the corresponding nitrones. The product nitrones can then be trapped in the inter- or intramolecular mode by a variety of reactions, including 1,3-dipolar cycloadditions, thereby leading to diversity oriented synthesis. The first section comprises the chemistry of the nitroso group with a brief discussion of the current methods for their generation together with the scope and limitations of these methods for carrying out nitroso ene reactions, with different examples of its potential as a powerful synthetic method to generate target drugs. The second chapter describes the results of the research programme and opens with the development of methods for the generation of functionalised nitroso compounds from different precursors including oximes and nitro compounds, using a range of reactants and conditions. The application of these methods in intramolecular nitroso ene reactions is then discussed. Chapter three presents the conclusions which have been drawn from the work presented in chapter two, and provides suggestions for possible directions of this research in the future. This work concludes with a formal account of the experimental procedures.

Resumo: O cupim subterrâneo Coptotermes gestroi (WASMANN, 1896) é uma das principais pragas responsável por danos econômicos em estruturas de madeira nas áreas urbanas do litoral e interior do sudeste brasileiro. A metodologia mais empregada no controle de cupins subterrâneos é a aplicação direta de inseticidas no solo, porém esse tipo de tratamento não é destinado à eliminação da colônia e sim a formar uma barreira química entre a fonte de alimento que está sendo consumida e a colônia dos cupins. Essa barreira química também não evita que alados infestem prédios na época da revoada, pois eles não terão contato com os inseticidas. Essas infestações podem continuar sendo subterrâneas em porões de edificações ou podem ser aéreas, onde os cupins nidificam em espaços entre os andares dos edifícios, pois estes locais oferecem o ambiente ideal para os cupins com água, abrigo e alimento. Uma estratégia alternativa que visa à eliminação da colônia dos cupins subterrâneos é a utilização da metodologia de isca. Nas iscas o ingrediente ativo é incorporado a substratos que contenham celulose, sendo assim, a quantidade de inseticida usado é mínima, pois ele não pode ser repelente e precisa ter ação lenta e as partes não consumidas das iscas podem ser removidas depois do tratamento. No presente estudo foram realizados bioensaios laboratoriais com C. gestroi para avaliar a toxicidade de cinco substâncias que foram sintetizadas tendo como modelo a molécula da sesamina, sendo duas amidas e três compostos piperonílicos. Adicionalmente, foi analisado um inibidor de síntese de quitina, representado pelo bistrifluron. Os resultados revelaram que para as duas amidas e composto piperonílico 1, apesar de serem tóxicos, seriam necessários novos bioensaios com concentrações acima de 10 000 ppm para verificar se ocorre o aumento da dose ingerida pelos cupins.
Abstract: The subterranean termite Coptotermes gestroi (WASMANN, 1896) is a major urban pest that attacks wooden structures throughout southeastern Brazil. The most widely employed method to control subterranean termites is the direct application of insecticides on soil, however this method does not eliminate the colonies, but creates a chemical barrier between termites and their food. Moreover, this chemical barrier does not preclude infestation of buildings by alate reproductives during the reproductive season as they don't come in contact with the insecticides. The infestation may remain underground at basements or in the spaces between the stories of the buildings, as these sites offer the ideal habitat for termites with water, protection and food. An alternative strategy eliminating subterranean termite's colonies is the use of baits. In baits the insecticide is embedded in cellulose substrates, thus minimizing, the amount of insecticide used, which can't be repellent and has to have slow mode of action, generating easily removable unconsumed wastes. In this study, we performed laboratory bioassays with C. gestroi to evaluate the toxicity of five substances that were synthesized with a model of the molecule of sesamine, being two amides and three piperonyl compounds. Additionally, was analyzed a chitin synthesis inhibitor, represented by bistrifluron. The results showed that the two amides and piperonyl compound 1, although toxic, would have to be tested at concentrations above 10 000 ppm to verify if there is an increase in the uptake of insecticide. Piperonyl compounds 3 and 5 shown to be effective at the concentration of 10 000 ppm, but new bioassays would be needed to confirm this results. Bistrifluron proved efficient to be used in baits, although causing a reduction in the intake of food by termites, but didn't influence the effect of the insecticide...

Resumo: A terapia ADEPT (antibody-directed enzyme prodrug therapy) tem sido caracterizada, em vários estudos experimentais focalizados na destruição de células tumorais, como uma alternativa à fármacos citotóxicos sistêmicos (anti-proliferativos). Nesta técnica, o pró-fármaco é ativado por enzimas exógenas que são levadas à célula tumoral por meio de anticorpos monoclonais (Mab). Neste contexto, horseradish peroxidase (HRP) e ácido 3-indolacético (IAA) constituem um dos sistemas mais citados de enzima e pró-fármaco aplicados à destruição de células tumorais com conjugados HRP-Mab. Peroxidases são enzimas inespecíficas e várias moléculas podem ser oxidadas pela suas formas ativas HRP-l e HRP-ll no ciclo clássico da peroxidase, que é dependente de peróxido de hidrogênio ou hidroperóxidos orgânicos. Por outro lado, somente NADH, dihidroxifumarato e a auxina de planta IAA, têm sido descritos como substratos para HRP em reação independente de peróxido de hidrogênio. O objetivo deste trabalho foi estudar o mecanismo pelo qual compostos β-dicarbonílicos são oxidados por HRP e explorar suas aplicações. Foi demonstrado que os compostos dicarbonílicos 2,4-pentanodiona (PD) e 3-metil-2,4-pentanodiona (MePD) são eficientemente oxidados pela HRP, na ausência de peróxido, em tampão fosfato pH 7,4, consumindo oxigênio presente em solução, o que não ocorreu com outros compostos β-dicarbonílicos testados (dimedona e acetoacetato). Observou-se também, via espectrofotometria, durante a reação com PD e MePD, que a enzima nativa passou à sua forma HRP-lll, além disso, a reação produziu espécies reativas de oxigênio (ERO), detectadas por quimiluminescência dependente de luminol e fluorescência dependente de diclorofluoresceína. Também foram realizadas reações de consumo de oxigênio com outros compostos que possuem grupamento...

In this technique, the prodrug is activated by exogenous enzymes delivered to tumor cells via monoclonal antibodies (MAb). In this context, horseradish peroxidase (HRP) and indole-3-acetic acid (IAA) constitute one of the most often cited systems of enzyme and prodrug applied to destroy tumor cells with HRP - MAb conjugates. Peroxidases are unspecific enzymes and several molecules can be oxidized by the active forms HRP-I and HRP-II in the classic peroxidase cycle, which depends on hydrogen peroxide or organic hydroperoxides. On the other hand, only NADH, dihydroxyfumarate and the plant auxin IAA have been described as substrates for HRP in a reaction independent of hydrogen peroxide. The objective of this work was to study the mechanism by which β-dicarbonyl compounds are oxidized by HRP and explore possible applications. We demonstrated by measuring oxygen uptake, that the dicarbonyls PD (2,4-pentanedione) and 3-MePD (3-methyl-2,4-pentanedione) can also be oxidized by HRP in the absence of peroxide, in phosphate buffer pH 7.4, consuming the oxygen present in solution, what didn't occur with other β-dicarbonyl compounds (dimedon and acetoacetate), under the same conditions. It was also observed, in the absorption spectrum during the reaction course with PD and 3-MePD, that the native enzyme was transformed to HRP-III; moreover, the reaction produced reactive oxidant species (ROS), detected by luminol-dependent chemiluminescence and dichlorofluorescein-fluorescence dependent. Reactions of oxygen uptake with other heme-compounds (cytochrome C, hemin, myoglobin and myeloperoxidase) had been carried to detect the especificity of the HRP in the oxidation reaction...

Resumo: Os compostos sulfurados no petróleo têm causado diversos problemas como os correlacionados à corrosão de equipamentos, envenenamento de catalisadores em processo de refino, qualidade dos produtos, além de liberação de gases tóxicos diretamente ao meio ambiente. Os compostos sulfurados em especial (enxofre elementar, difenil dissulfeto e 1-butanotiol) podem agravar estes problemas, sendo os principais causadores de corrosão de equipamentos nas refinarias de petróleo. Devido a tais considerações, a proposição deste trabalho é o desenvolvimento de metodologias eletroanalíticas para determinação de compostos sulfurados em gasolina, utilizando os eletrodos de filme de mercúrio, amálgama sólido e hexacianoferrato de cobre. No primeiro trabalho desenvolvido utilizou-se o eletrodo filme de mercúrio juntamente com as técnicas eletroanalíticas de voltametria de varredura linear (VVL), onda quadrada (VOQ) e pulso diferencial (VPD) em solução de acetato de sódio 1,4 mol L-1 e ácido acético 2% em metanol, como eletrólito suporte. O método apresentou limites de detecção na ordem de 10-9 a 10-4 mol L-1 para as técnicas eletroanalíticas de VVL, VOQ e VPD, inferiores aos já relatados na literatura usando método análogo. A quantificação dos compostos de enxofre em amostras de gasolina, a partir do monitoramento do sinal de redução sobre a superfície do eletrodo filme de mercúrio, utilizando a técnica de voltametria de onda quadrada, foi possível sem tratamento prévio da amostra, cujo procedimento mostrou ser bastante eficiente não provocando qualquer interferência associada aos constituintes da matriz, exibindo valores de 3,5x10-8, 3,7x10-7 e 4,2x10-8 mol L-1 para enxofre elementar, difenil dissulfeto e 1-butanotiol, respectivamente.

Abstract: The presence of sulfur compounds in petroleum has caused several problems including those related to the corrosion of equipments, and the quality of final products, as well as the emission of toxic gases to the environment. Sulfur compounds (elemental sulfur, diphenyl disulfide and 1-butanethiol), can increase these problems, being the main causes of corrosion of equipments in the refineries of petroleum. Based on these assumptions, the principal proposal of this work is the development of electroanalytical methodology for determination of sulfur compounds in gasoline using the electrodes of mercury film, amalgam solid and copper hexacyanoferrate. In the first developed work the mercury film electrode was used together with the electroanalytical techniques of linear scan voltammetry (LSV), square wave voltammetry (SWV) and differential pulse voltammetry (DPV) in solution of 1.4 mol L-1 sodium acetate and acetic acid 2% in methanol. The method presented detection limits in the order from 10-9 to 10-4 mol L-1 for the electroanalytical techniques of LSV, SWV and DPV. These limits are inferior to the previous related in the literature using similar method. The quantification of the sulfur compounds in gasoline samples, starting from the monitoring of the reduction sign on the mercury film electrode surface using the technique of square wave voltammetry was possible without previous sample treatment, whose procedure showed to be efficient, it not provoking any interference associated to the sample, exhibiting values of 3.5x10-8, 3.7x10-7 and 4.2x10-8 mol L-1 for elemental sulfur, diphenyl disulfide and 1-butanethiol, respectively. The quantification in the samples of gasoline in recovery terms showed that the methodology electroanalytical supplied quite acceptable results with recovery levels and precision compatible to the found by other techniques.

Resumo: Neste trabalho pesquisamos variações das propriedades elétricas de filmes ultrafinos de diferentes materiais, utilizados como unidades sensoriais de uma "língua eletrônica", simulando os resultados obtidos em diferentes paladares com um modelo de circuito elétrico equivalente, visando uma melhor compreensão do mecanismo de transdução envolvido. Foram utilizados filmes ultrafinos de quitosana, ftalocianina, polipirrol e perileno, que serviram de elementos transdutores do dispositivo, similar às papilas gustativas na língua humana, pois a diferença de resposta entre eles pode ser utilizada como uma impressão digital dos líquidos analisados. Esses materiais foram depositados sobre lâminas de quartzo e eletrodos interdigitados através das técnicas Langmuir-Blodgett (LB), automontagem e evaporação a vácuo. Inicialmente o trabalho foi na fabricação de filmes ultrafinos para familiarização das técnicas e equipamentos de medidas. Pôde-se verificar boa adesão dos materiais depositados sobre os eletrodos interdigitados mesmo após excessivas lavagens em água Milli-Q, permitindo sua reutilização na "língua eletrônica". Os eletrodos cobertos com filmes ultrafinos foram imersos em soluções 1 mM e 1μM ácidas, salgadas, doces, amargas e umami utilizando medida de impedância elétria e um modelo de circuito elétrico equivalente já existente na literatura. Analisamos a sensibilidade de resposta a uma temperatura de aproximadamente '20 GRAUS', avaliando como os parâmetros envolvidos no circuito elétrico equivalente variam de acordo com o tipo de solução analisada, nas concentrações 1 mM e 1μM, e ainda como esses parâmetros são afetados em um mesmo material na presença de diferentes analitos. Os resultados obtidos foram também analisados pelo método estatístico de Análise de Componentes Principais (PCA, do inglês "Principal Component Analysis") e Espectroscopia Raman.
Abstract: In this work we study variations in the electrical properties of ultra-thin films of different materials, used as individual sensing units in an "electronic tongue", simulating the results obtained in distinct tastants with an equivalent electric circuit, envisaging a better comprehension of the transducing mechanism involved. Ultra-thin films of chitosan, copper phtalocyanine, polypyrrole and perylene were used as transducers in the device, similar to the gustative papilae in the human tongue, as their electrical differences can be used as a fingerprint of the liquids analysed. The materials were deposited onto quartz plates and interdigitated electrodes through Langmuir-Blodgett (LB), layer-by-layer and vacuum evaporation techniques. Initially, we start the fabrication of the ultra-thin films to a better familiarization with equipments and tecniques. There was a good adhesion of the deposited films onto the interdigitated electrodes, even after excessive washings in Milli-Q water, allowing the re-use of the "eletronic tongue" system. The electrodes covered with ultra-thin films were have been soaked in 1mM and 1μM solutions of acidic, sweet, sour and bitter substances, using impedance spectroscopy as the measured technique and an equivalent circuit model already existent in the literature. The sensitivity of response at '20 GRAUS' was evaluated investigating seeking of how the involved parameters in the equivalent electric circuit varied according to the sort of solution analysed at mM and μM concentrations, and how they are affected by each material due to the presence of distinct analytes. The obtained results were also analysed by Principal Component Analysis and Raman Spectroscopy.

Resumo: Várias pesquisas realizadas com compostos a base de lítio tem mostrado resultados satisfatórios na redução da expansão associada à reação álcali-sílica (RAS), mas ainda existem muitas dúvidas sobre seus mecanismos de ação. A presente pesquisa avaliou os efeitos de uma adição química a base de nitrato de lítio (LiNO3) na redução da expansão associada a RAS, utilizando várias dosagens. Os estudo dos efeitos do LiNO3 na RAS foi feito pelo método acelerado das barras de argamassa (ASTM C-1260) utilizando dois tipos de agregado reativo. Também foram realizados ensaios de expansão com uma adição mineral a base de cinza volante a fim de correlacionar os efeitos de uma adição mineral com uma química na redução da expansão devido a RAS. Ensaios de resistência à compressão e trabalhabilidade foram realizados também buscando algum efeito do LiNO3 nestas propriedades. Os resultados do ensaio ASTM C-1260 indicaram que as adições de lítio foram efetivas na redução da expansão para os dois tipos de agregados reativos, sendo que para as condições e materiais utilizados na presente pesquisa foi necessário uma de adição de LiNO3 com relação molar (Li2O/Na2Oeq) de 7,00 para reduzir a expansão ao valor aceitável pela norma de 0,10% aos 16 dias. Foi observado também intensidades de redução da expansão diferentes entre os dois tipos de agregados estudados devido a diferença de reatividade dos mesmos. Verificou-se um limite de adição de lítio para o basalto, onde não havia mais redução significativa de expansão com o aumento da dosagem de adição. Observou-se também que as misturas contendo LiNO3 reduziram a expansão ao longo dos 30 dias, enquanto nas misturas contendo FA a expansão continuou a aumentar ao longo do teste. Os ensaios de condição de trabalhabilidade e de resistência à compressão mostraram que o LiNO3 não afeta consideravelmente estas propriedades.Abstract: Lithium compounds have been shown satisfactory results for the reduction of the expansion due to alkali-silica reaction (ASR), but there are many doubts about its mechanisms of action. The present research evaluated the effects of a chemical addition to lithium nitrate based (LiNO3) on the reduction of expansion associated with ASR, utilizing several dosages. For the study of the effects of the LiNO3 on the ASR it was used the accelerated mortar bar method (ASTM C-1260), with two kinds of reactivate aggregate. Mortar bars were molded also with a mineral addition of fly ash based (FA) with the objective to compare the effects of a mineral addition with a chemistry on the expansion due ASR. Compressive strength and consistence index tests had been carried also for searching some effects of the LiNO3 at these properties. The results from ASTM C-1260 showed that the addition of LiNO3 were effective on the expansion reduction for two kinds of reactive aggregate, which current conditions and materials on this research required a LiNO3 addition with (Li/Naeq) of 7,00 molar ratio to decrease the expansion to an acceptable value of 0,10% on 16 days. Also, the intensity of the expansion reduction was observed between two kinds of studied aggregates by their reactivity difference. A lithium additive upper bound was verified for the basalt, where it did not have more significant reduction of expansion with the increase of the dosage of addition. Also, was observed that admixtures that contained LiNO3 have reduced the expansion trough 30 days, while on the admixtures that contained FA the expansion grew up. The results obtained for the compressive strength and consistence index tests showed no significant differences between mixtures with and without LiNO3 admixture.

Full textAbstract:
This volume contains the first Italian critical edition with introduction, translation and commentary of Euripides’ Iphigenia in Aulis. The tragedy, exhibited posthumously in 405 BCE, stages the first mythical segment of the Trojan War, namely the sacrifice of Iphigenia, daughter of king Agamemnon, head of the Greek army, in order to propitiate the winds that should lead the navy to Troy. A tragedy of intrigue and unveiling, in which all the characters try to oppose the sacrifice, judged to be an impiety despite its sacred essence. It is therefore a tragedy without gods, in which characters of modest moral stature move, unstable, ready to sudden changes of mind, and among whom the protagonist stands out: the girl who, having overcome the dismay for the destiny awaiting her, voluntarily moves towards death on the altar, for a flimsy patriotic ideal and with the illusion of achieving immortal glory. Since the end of the eighteenth century, the text of this tragedy, handed over to us by the manuscript tradition, has been exposed more than others to a rigorous philological criticism that has broken its unity, through considerable expunctions of entire sections and sequences of verses. The volume traces the phases of this critical work, showing its methods – and sometimes its excesses – and choosing a balance line in the constitution of the text. The overall exegesis of the tragedy, which I propose in this study, consists in the belief that, despite the exodus being spurious, the finale, in view of which the entire dramaturgy was composed, still had to contemplate Iphigenia’s salvation. In fact, if the Panhellenic ideal of defence against the barbarians is now meaningless, and if a war of destruction, to begin with, needs the death of an innocent person, then this death must be transcended and the horror of human sacrifice must dissolve. It therefore seems that, once political current events become opaque, the poet’s research tends to create situations of great patheticism in an aesthetic setting of refined beauty.

This project summarizes the results from 2000–2020and evaluates the trueness andthequality control (QC) procedures of the ongoing polycyclic aromatic hydrocarbon (PAH)and trace element measurements in Finlandrelating to Air Quality (AQ) Directive 2004/107/EC. The evaluation was focused on benzo(a)pyrene and other PAH compounds as well as arsenic, cadmium and nickel in PM10and deposition. Additionally, it included lead and other metals in PM10and deposition, gaseous mercury and mercury deposition, andbriefly other specificAQ measurements such as volatile organic compounds (VOC)and PM2.5chemical composition. This project was conducted by the National Reference Laboratory on air quality and thiswas the first time these measurements were assessed. A major part of the project was field and laboratory audits of the ongoing PAH and metal measurements. Other measurements were briefly evaluated through interviews and available literature. In addition, the national AQ database, the expertise of local measurement networks and related publications were utilised. In total, all theseven measurement networks performing PAH and metal measurements in 2019–2020took part in the audits. Eleven stations were audited while these measurements are performed at 22 AQ stations in Finland. For the large networks, one station was chosen to represent the performance of the network. The audits included also six laboratories performing the analysis of the collected samples. The audits revealed the compliance of the measurements with the AQ Decree 113/2017, Directive 2004/107/EC and Standards of the European Committee for Standardization(CEN). In addition, general information of the measurements, instruments and quality control procedures were gained. The results of the laboratory audits were confidential,but this report includes general findings, and the measurement networks were informed on the audit results with the permission of the participating laboratories. As a conclusion, the measurementmethodsusedwere mainly reference methods. Currently, all sampling methods were reference methods; however, before 2018 three networks used other methods that may have underestimated concentrations. Regarding these measurements, it should be noted the results are notcomparable with the reference method. Laboratory methods were reference methods excluding two cases, where the first was considered an acceptable equivalent method. For the other, a change to a reference method was strongly recommended and this realized in 2020. For some new measurements, the ongoing QC procedures were not yet fully established, and advice were given. Some networks used consultant for calibration and maintenance, and thus theywere not fully aware of the QC procedures. EN Standards were mostly followed. Main concerns were related to the checks of flow and calculation of measurement uncertainty, and suggestions for improvement were given. When the measurement networks implement the recommendations given inthe audits, it can be concluded that the EN Standards are adequately followed in the networks. In the ongoing sampling, clear factors risking the trueness of the result were not found. This applies also for the laboratory analyses in 2020. One network had concentrations above the target value, and theindicative measurementsshould be updated to fixed measurements.

Under the current IDBG Corporate Results Framework (CRF) 2020-2023 (https://crf.iadb.org/en), the IDB committed to reach 30% of the total amount approved (including all lending operations) of climate finance during this period. In 2020, the IDB Group - composed of the IDB, IDB Lab (formerly the Multilateral Investment Fund) and IDB Invest - approved US$3.9 billion in climate finance as per the MDB climate finance tracking methodology. This resource is aimed at development activities carried out by the public and private sectors that reduce greenhouse gas (GHG) emissions and thus mitigate climate change, and/or that reduce vulnerability to climate change and contribute to an adaptation process. This amount represented 19.5% of the IDB Groups total approved amount for 2020. The IDB only climate finance in 2020 was 15%, equivalent to US$ 2 billion. If the COVID-19 related investments are excluded, the IDB climate finance reached 30%. Changes in demand from countries to respond to the pandemic affected the overall climate finance results by shifting the priority to social and fiscal sectors and to projects that could provide faster liquidity.

Full textAbstract:
Multiple oil discoveries reveal the global scale and economic importance of a distinctive reservoir type composed of possible microbial lacustrine carbonates like the Lower Cretaceous pre-salt reservoirs in deepwater offshore Brazil and Angola. Marine microbialite reservoirs are also important in the Neoproterozoic to lowest Cambrian starta of the South Oman Salt Basin as well as large Paleozoic deposits including those in the Caspian Basin of Kazakhstan (e.g., Tengiz field), and the Cedar Creek Anticline fields and Ordovician Red River “B” horizontal play of the Williston Basin in Montana and North Dakota, respectively. Evaluation of the various microbial fabrics and facies, associated petrophysical properties, diagenesis, and bounding surfaces are critical to understanding these reservoirs. Utah contains unique analogs of microbial hydrocarbon reservoirs in the modern Great Salt Lake and the lacustrine Tertiary (Eocene) Green River Formation (cores and outcrop) within the Uinta Basin of northeastern Utah. Comparable characteristics of both lake environments include shallowwater ramp margins that are susceptible to rapid widespread shoreline changes, as well as compatible water chemistry and temperature ranges that were ideal for microbial growth and formation/deposition of associated carbonate grains. Thus, microbialites in Great Salt Lake and from the Green River Formation exhibit similarities in terms of the variety of microbial textures and fabrics. In addition, Utah has numerous examples of marine microbial carbonates and associated facies that are present in subsurface analog oil field cores.

Full textAbstract:
For meat and meat products, secondary processes are those that relate to the downstream of the primary chilling of carcasses. Secondary processes include maturation chilling, deboning, portioning, mincing and other operations such as thermal processing (cooking) that create fresh meat, meat preparations and ready-to-eat meat products. This review systematically identified and summarised information relating to antimicrobial resistance (AMR) during the manufacture of secondary processed meatand meat products (SPMMP). Systematic searching of eight literature databases was undertaken and the resultantpapers were appraised for relevance to AMR and SPMMP. Consideration was made that the appraisal scores, undertaken by different reviewers, were consistent. Appraisal reduced the 11,000 initially identified documents to 74, which indicated that literature relating to AMR and SPMMP was not plentiful. A wide range of laboratory methods and breakpoint values (i.e. the concentration of antimicrobial used to assess sensitivity, tolerance or resistance) were used for the isolation of AMR bacteria.The identified papers provided evidence that AMR bacteria could be routinely isolated from SPMMP. There was no evidence that either confirmed or refuted that genetic materials capable of increasing AMR in non-AMR bacteria were present unprotected (i.e. outside of a cell or a capsid) in SPMMP. Statistical analyses were not straightforward because different authors used different laboratory methodologies.However, analyses using antibiotic organised into broadly-related groups indicated that Enterobacteriaceaeresistant to third generation cephalosporins might be an area of upcoming concern in SPMMP. The effective treatment of patients infected with Enterobacteriaceaeresistant to cephalosporins are a known clinical issue. No AMR associations with geography were observed and most of the publications identified tended to be from Europe and the far east.AMR Listeria monocytogenes and lactic acid bacteria could be tolerant to cleaning and disinfection in secondary processing environments. The basis of the tolerance could be genetic (e.g. efflux pumps) or environmental (e.g. biofilm growth). Persistent, plant resident, AMR L. monocytogenes were shown by one study to be the source of final product contamination. 4 AMR genes can be present in bacterial cultures used for the manufacture of fermented SPMMP. Furthermore, there was broad evidence that AMR loci could be transferred during meat fermentation, with refrigeration temperatures curtailing transfer rates. Given the potential for AMR transfer, it may be prudent to advise food business operators (FBOs) to use fermentation starter cultures that are AMR-free or not contained within easily mobilisable genetic elements. Thermal processing was seen to be the only secondary processing stage that served as a critical control point for numbers of AMR bacteria. There were significant linkages between some AMR genes in Salmonella. Quaternary ammonium compound (QAC) resistance genes were associated with copper, tetracycline and sulphonamide resistance by virtue of co-location on the same plasmid. No evidence was found that either supported or refuted that there was any association between AMR genes and genes that encoded an altered stress response or enhanced the survival of AMR bacteria exposed to harmful environmental conditions.

Full textAbstract:
This study leveraged existing data infrastructure and relationships from the Feed the Future Senegal Naatal Mbay (“flourishing agriculture”) project, funded by the US Agency for International Development (USAID) and implemented by RTI International from 2015 to 2019. The research informed and empowered farmer organizations to track and respond to rural households in 2020 as they faced the COVID-19 pandemic. Farmer organizations, with support from RTI and local ICT firm STATINFO, administered a survey to a sample of 800 agricultural households that are members of four former Naatal Mbay–supported farmer organizations in two rounds in August and October 2020. Focus group discussions were conducted with network leadership pre- and post–data collection to contextualize the experience of the COVID-19 shock and to validate findings. The results showed that farmers were already reacting to the effects of low rainfall during the 2019 growing season and that COVID-19 compounded the shock through disrupted communications and interregional travel bans, creating food shortages and pressure to divert seed stocks for food. Food insecurity effects, measured through the Household Food Insecurity Access Scale and cereals stocks, were found to be greater for households in the Casamance region than in the Kaolack and Kaffrine regions. The findings also indicate that farmer networks deployed a coordinated response comprising food aid and access to personal protective equipment, distribution of short-cycle legumes and grains (e.g., cowpea, maize) and vegetable seeds, protection measures for cereals seeds, and financial innovations with banks. However, food stocks were expected to recover as harvesting began in October 2020, and the networks were planning to accelerate seed multiplication, diversify crops beyond cereals, improve communication across the network. and mainstream access to financial instruments in the 2021 growing season. The research indicated that the previous USAID-funded project had likely contributed to the networks’ COVID-19 resilience capacities by building social capital and fostering the new use of tools and technologies over the years it operated.

Development of three-dimensional wetting and drying algorithm for the Geophysical Scale Transport Multi-Block Hydrodynamic Sediment and Water Quality Transport Modeling System (GSMB). Engineer Research and Development Center (U.S.), July 2021. http://dx.doi.org/10.21079/11681/41085.
Full textAbstract:
The Environmental Laboratory (EL) and the Coastal and Hydraulics Laboratory (CHL) have jointly completed a number of large-scale hydrodynamic, sediment and water quality transport studies. EL and CHL have successfully executed these studies utilizing the Geophysical Scale Transport Modeling System (GSMB). The model framework of GSMB is composed of multiple process models as shown in Figure 1. Figure 1 shows that the United States Army Corps of Engineers (USACE) accepted wave, hydrodynamic, sediment and water quality transport models are directly and indirectly linked within the GSMB framework. The components of GSMB are the two-dimensional (2D) deep-water wave action model (WAM) (Komen et al. 1994, Jensen et al. 2012), data from meteorological model (MET) (e.g., Saha et al. 2010 - http://journals.ametsoc.org/doi/pdf/10.1175/2010BAMS3001.1), shallow water wave models (STWAVE) (Smith et al. 1999), Coastal Modeling System wave (CMS-WAVE) (Lin et al. 2008), the large-scale, unstructured two-dimensional Advanced Circulation (2D ADCIRC) hydrodynamic model (http://www.adcirc.org), and the regional scale models, Curvilinear Hydrodynamics in three dimensions-Multi-Block (CH3D-MB) (Luong and Chapman 2009), which is the multi-block (MB) version of Curvilinear Hydrodynamics in three-dimensions-Waterways Experiments Station (CH3D-WES) (Chapman et al. 1996, Chapman et al. 2009), MB CH3D-SEDZLJ sediment transport model (Hayter et al. 2012), and CE-QUAL Management - ICM water quality model (Bunch et al. 2003, Cerco and Cole 1994). Task 1 of the DOER project, “Modeling Transport in Wetting/Drying and Vegetated Regions,” is to implement and test three-dimensional (3D) wetting and drying (W/D) within GSMB. This technical note describes the methods and results of Task 1. The original W/D routines were restricted to a single vertical layer or depth-averaged simulations. In order to retain the required 3D or multi-layer capability of MB-CH3D, a multi-block version with variable block layers was developed (Chapman and Luong 2009). This approach requires a combination of grid decomposition, MB, and Message Passing Interface (MPI) communication (Snir et al. 1998). The MB single layer W/D has demonstrated itself as an effective tool in hyper-tide environments, such as Cook Inlet, Alaska (Hayter et al. 2012). The code modifications, implementation, and testing of a fully 3D W/D are described in the following sections of this technical note.
