Espectroscopia no infravermelho e método quimiométrico para a pesquisa de antimicrobianos em leite da microrregião de Pato Branco - PR

Considering the social and economic importance that the milk has, the objective of this study was to evaluate the incidence and quantifying antimicrobial residues in the food. The samples were collected in dairy industry of southwestern Paraná state and thus they were able to cover all ten municipalities in the region of Pato Branco. The work focused on the development of appropriate models for the identification and quantification of analytes: tetracycline, sulfamethazine, sulfadimethoxine, chloramphenicol and ampicillin, all antimicrobials with health interest. For the calibration procedure and validation of the models was used the Infrared Spectroscopy Fourier Transform associated with chemometric method based on Partial Least Squares regression (PLS - Partial Least Squares). To prepare a work solution antimicrobials, the five analytes of interest were used in increasing doses, namely tetracycline from 0 to 0.60 ppm, sulfamethazine 0 to 0.12 ppm, sulfadimethoxine 0 to 2.40 ppm chloramphenicol 0 1.20 ppm and ampicillin 0 to 1.80 ppm to perform the work with the interest in multiresidues analysis. The performance of the models constructed was evaluated through the figures of merit: mean square error of calibration and cross-validation, correlation coefficients and offset performance ratio. For the purposes of applicability in this work, it is considered that the models generated for Tetracycline, Sulfadimethoxine and Chloramphenicol were considered viable, with the greatest predictive power and efficiency, then were employed to evaluate the quality of raw milk from the region of Pato Branco . Among the analyzed samples by NIR, 70% were in conformity with sanitary legislation, and 5% of these samples had concentrations below the Maximum Residue permitted, and is also satisfactory. However 30% of the sample set showed unsatisfactory results when evaluating the contamination with antimicrobials residues, which is non conformity related to the presence of antimicrobial unauthorized use or concentrations above the permitted limits. With the development of this work can be said that laboratory tests in the food area, using infrared spectroscopy with multivariate calibration was also good, fast in analysis, reduced costs and with minimum generation of laboratory waste. Thus, the alternative method proposed meets the quality concerns and desired efficiency by industrial sectors and society in general.

El reverso del sujeto: provocaciones de Foucault para pensar en derechos humanos

Este ensayo pretende discutir los modos de subjetivación propuestos por Michel Foucault y los derechos humanos. Tomando esas implicaciones Faucaultianas del cuidado de sí mismo y de una estilización de la existencia de la constitución en nuestras vidas, es posible substituir el llamado a lo universal y lo esencial por formas más disonantes de subjetivación, significativamente más singulares. Este ensayo se enfocó en un referencial bibliográfico que contempla obras de Foucault y obras sobre el autor, sobre derechos humanos, sin perder de vista las implicaciones practicas y las experiencias del campo jurídico. Sin embargo, la percepción de las insuficiencias de la teoría tradicional de los derechos humanos de encarar las diferencias de la subjetividad y de promover la autonomía y la emancipación de los sujetos, evidencia el motivo por el cual buscamos elementos nuevos de la subjetividad en la filosofía de Foucault y en una teoría critica de los derechos humanos..

Gestão Técnica Centralizada em Edifícios da Força Aérea

A investigação centra-se na aplicação da Gestão Técnica Centralizada como instrumento para a melhoria da eficiência energética dos edifícios e infraestruturas da Força Aérea Portuguesa e diminuição de pessoal afeto à sua manutenção, tendo por base, dois casos de estudo, o edifício QC12 do Centro de Formação Militar e Técnica da Força Aérea e o ECOTERMOLAB, pertencente ao Instituto de Soldadura e Qualidade. Da análise desenvolvida conclui-se que o funcionamento dos edifícios ECOTERMOLAB e QC12, com controlo por GTC, representam anualmente uma diminuição de consumo energético em 30% e 44% respetivamente e, uma redução de 50% nos recursos humanos afetos à instalação do QC12. Da viabilidade económica obtiveram-se as métricas de Valor Atual Líquido e a Taxa Interna de Rentabilidade positivos e um Período de Recuperação do Investimento, de 11,5 anos para ECOTERMOLAB e 10,7 anos para QC12. Por fim, teceram-se algumas recomendações, dirigidas à Força Aérea Portuguesa, com o intento de melhorar a eficiência energética elétrica e a redução de recursos humanos afetos. Abstract: The research is focused in the application of the Centered Technique Management as an instrument to improve the Portuguese Air Force buildings and infrastructures’ energetic efficiency and to reduce the staff in charge of its maintenance, based on two study cases, QC 12 building in The Air Force Military and Technique Training Center and ECOTERMOLAB, which belongs to Instituto de Soldadura e Qualidade (Quality and Welding Institute). From the analysis, one can conclude that the functioning of the ECOTERMOLAB and QC12 buildings, with GTC control, represents an annual consumption of less 30% and 44% respectively and a 50% reduction in the human resources of the QC 12. From the economical viability, it was possible to get the figures of the Net Present Value and the Internal Rate of Return and a Period of Return on Investment of 11,5 years for ECOTERMOLAB and 10,7 years for QC 12. Finally, some recommendations to the Portuguese Air Force were made, aiming the improvement of the electrical energetic efficiency and a reduction in human resources.

Light polarization sensitive photodetectors with m- and r-plane homoepitaxial ZnO/ZnMgO quantum wells

Homoepitaxial ZnO/(Zn,Mg)O multiple quantum wells (MQWs) grown with m- and r-plane orientations are used to demonstrate Schottky photodiodes sensitive to the polarization state of light. In both orientations, the spectral photoresponse of the MQW photodiodes shows a sharp excitonic absorption edge at 3.48 eV with a very low Urbach tail, allowing the observation of the absorption from the A, B and C excitonic transitions. The absorption edge energy is shifted by ∼30 and ∼15 meV for the m- and r-plane MQW photodiodes, respectively, in full agreement with the calculated polarization of the A, B, and C excitonic transitions. The best figures of merit are obtained for the m-plane photodiodes, which present a quantum efficiency of ∼11%, and a specific detectivity D* of ∼6.4 × 1010 cm Hz1/2/W. In these photodiodes, the absorption polarization sensitivity contrast between the two orthogonal in-plane axes yields a maximum value of (R⊥/R||)max ∼ 9.9 with a narrow bandwidth of ∼33 meV.

La réaction de Gorgias au Poème de Parménide : élaboration d'une rhétorique comme fuite de l'ontologie.

L’objectif principal de ce mémoire de maîtrise sera d’examiner en détails les arguments que Gorgias avance dans le Traité sur le non-être pour supporter sa thèse de l’impossibilité de la connaissance. Ces arguments sont au nombre de trois : a) rien n’est; b) Si quelque chose est, c’est inconnaissable; c) Si c’est connaissable, c’est indémontrable aux autres. En plus de s’attaquer à la thèse parménidienne de la correspondance entre le « penser » (noein) et « l’être » (einai), ces arguments viennent justifier l’art rhétorique. En effet, sans la connaissance qui nous permettrait de départager le vrai du faux, l’être humain n’a plus rien d’autre que ses intérêts personnels et les moyens rhétoriques de les faire triompher. Dans un tel contexte, la rhétorique devient, à proprement parler, la seule science véritablement légitime.

La Escuela de Administración viene desarrollando proyectos de investigación encaminados a identificar las oportunidades de las empresas colombianas frente al Tratado de Libre Comercio con Estados Unidos. Por lo que este estudio busca entender por qué Estados Unidos es el principal socio de Colombia en términos de exportaciones. Dentro del presente estudio se presentan cifras de Colombia y Estados Unidos desde el año 2012 hasta el año 2015, los cuales permitieron identificar, analizar y estudiar la relación económica, el comportamiento en el tiempo y la evolución de ambos países. Con la entrada que tenía el TLC, el gobierno de Colombia y EE.UU. trataron de construir la confianza a mediano y largo plazo para los empresarios. Así que el trabajo se centró en analizar paso a paso las principales características que hicieron el TLC una de las relaciones más importantes que ha tenido hasta ahora el país, sin dejar de lado el contexto económico global y el contexto bilateral. Mediante WISER Trade la cual es una base de datos de flujos de comercio internacional, se recopilo la información necesaria para determinar cuáles son las principales oportunidades comerciales y se determinó que el sector agropecuario, y el sector industrial reflejan una alta competitividad con los Estados Americanos de Illinois, Indiana e Idaho, reflejando en las cifras de 2012 a 2015 un incremento en las exportaciones.

Le Corbusier (1887–1965)

Le Corbusier was a Swiss architect and urbanist who acquired French nationality in 1930, having set up his studio (“the atelier of patient research”) in that country. Just as he assumed an unconditional continuity in relation to the past, he also clearly confronted the circumstances of his time. Many of his works became icons of Modernism, like the Villa Savoye (1928), the Marseilles Housing Unit (1945), the Ronchamp Chapel (1950), the Convent of Sainte-Marie de la Tourette (1953) and the Chandigarh Capitol Complex (1950-55), to mention just a few examples. His architecture reflected the development of a modern industrialized economy, a western avant-garde society and a vibrant political and social context. He made a mark not only with his constructed work, but also with designs that were never built (and which were progressive in character), his painting (which reflected his experimentalist nature) and with his theoretical texts, which today bear witness to his modernist doctrine. Le Corbusier was above all one of the most prolific thinkers of Modernism, and one of the greatest figures of the 20th century.

Una proposta di edizione digitale semantica della vita di Federico da Montefeltro di Vespasiano da Bisticci

Il patrimonio culturale è l’espressione della comunità a cui si riferisce e il digitale può essere un valido strumento per raccontare le storie relative ai beni culturali affinché siano, non solo studiati, ma anche recepiti nel loro significato più profondo da più pubblici. L’inserimento di testi manoscritti sul web utilizzando le tecnologie dei Linked Data facilitano la fruizione del testo da parte dell’utente non specializzato e la creazione di strumenti per la ricerca. La proposta di digitalizzazione della tesi ha come oggetto la vita di Federico da Montefeltro scritta da Vespasiano da Bisticci utilizzando i vocabolari schema.org, FOAF e Relationship per la marcatura del testo e i Content Management System per la pubblicazione dei dati. In questo modo sarà possibile avere un sito web in cui potrà essere curato anche l’aspetto grafico seguendo le regole della user experience e dell’information achitecture per valorizzare le figure del duca di Urbino e del cartolaio fiorentino.

Hairpin windings for high reliability and high power density electrical machines

In the last years the increasing demand of higher torque and power densities has led to the adoption of hairpin windings (HWs) in electrical machines, mainly in those intended for automotive applications. However, this winding topology is quite sensitive to AC losses, hence one of their main challenges is represented by their reduction. This work deals with different design aspects related to the enhancements of some performance figures of rotating electrical machines for traction applications, above all power density and reliability, mainly through the adoption of HWs.

Enhanced switchgear connection testing through augmented reality: early developments

Augmented reality is an emerging field of interactive design in which virtual material is seamlessly blended with displays of real world environments. The tremendous potential of augmented reality has begun to be explored with the emergence of personal mobile devices capable of constructing engaging augmented reality experiences. This work is part of a project aiming at using augmented reality goggles to bring advance information to the user interacting with switch-gear during automation cabling. In particular we will be focusing on the recognition and definition of the figures of the component on the AR device. In this part we are using standard camera that allows us to get real images and helps us to localize the gearbox in space through ARUCO marker and we can exploit in order to re-project the actual shape of the component that are currently interested in manipulation by exploiting the data provided by the database. The experiments are carried out using the camera to get the images of the real world switch-gear and re-project those images with the component superimposed on it. Using transforms of the database we did localization to re-project the rendered image of component exactly on the real world component, which can be further integrated in AR goggles to see the component superimposed in real-time.

Women, sources, and rhetoric in George Pettie’s A petite pallace of Pettie his pleasure

Ce mémoire, Women, Sources, and Rhetoric in George Pettie’s A Petite Pallace of Pettie his Pleasure, étudie la collection de romans courts de l’anglais moderne intitulée A Petite Pallace of Pettie his Pleasure (1576) et l’identifie comme une collection pour les femmes et comme un précurseur du style euphuistique. Le mémoire est constitué de trois chapitres. Dans le premier chapitre, j’analyse la position des femmes au début de l’Angleterre moderne, alors que A Petite Pallace est dédié aux femmes. Le deuxième chapitre traite des éléments structuraux de chaque histoire comprise dans la collection. Je relève également les modifications faites par l’auteur à des histoires d’origine afin de les adapter à ses lecteurs et afin d’attirer davantage d’attention. Le dernier chapitre porte principalement sur les figures de style utilisées par Pettie pour éblouir ses lecteurs et démontrer toute la richesse de la langue anglaise
