Abstract:
Abstract The Microfilm™ Test System is intended for quantitative microbiology and consists of three types of Microfilms for aerobic plate count (Microfilm APC), total coliform and Escherichia coli count (Microfilm TCEc), and yeast and mold count (Microfilm YMC). This study evaluated the performance of the Microfilm Test System against International Organization for Standardization (ISO) methods on 20 food matrixes and 2 environmental surfaces. Ruggedness, robustness, and stability were also determined, while inclusivity and exclusivity studies were performed on Microfilm TCEc and YMC. An independent laboratory evaluated the performance on four food matrixes and one environmental surface. No significant differences and high correlation coefficients were observed between the Microfilm Test System and the corresponding ISO methods (ISO 4833-1:2013 for APC, ISO 4832:2006 for total coliform count, ISO 16649-2: 2001 for E. coli, and ISO 21527 Part 1 and Part 2 for YMC) in spiked food matrixes and environmental samples. These results were corroborated by the independent laboratory. Inclusivity and exclusivity studies for Microfilm TCEc showed expected results for all the E. coli strains tested (blue-violet or violet color), while the related coliforms showed the expected blue-green colonies on the Microfilm. Similarly, all 100 fungal strains tested showed typical growth on Microfilm YMC. Exclusivity testing on Microfilm TCEc and YMC showed no growth of nontarget organisms. Robustness and ruggedness studies showed no significant differences in mean difference counts at varying incubation temperatures and times. Stability studies on three lots of the Microfilm Test System showed that it is stable at 2–25°C for 12 months and at 45°C for 6 weeks.

Abstract:
We integrated the determinant persuasive messages of microfilms with the elaboration likelihood model to examine consumers' affective and cognitive attitude change and purchase intention. Participants were 316 Taiwanese consumers who had seen "House of Little Moments," a successful microfilm marketing campaign in Taiwan. The empirical results of confirmatory factory analysis with structural equation modeling revealed that argument quality predicted cognitive responses and story plot predicted affective responses; celebrity effect and microfilm popularity had positive effects on both affective and cognitive responses; and purchase intention was affected by both cognitive and affective responses, with affective responses having the stronger effect. These results imply that the extent of consumers' emotional reaction to persuasive messages has a particularly important influence on purchase intention in story-based advertising. Therefore, understanding the effect of persuasive messages in microfilm marketing is essential for both advertisers and marketers.

Abstract:
Abstract Background The Enterobacteriaceae and generic Escherichia coli are routinely enumerated in foods as part of product release criteria, or in the case of swabs, for environmental monitoring. Objective Microbiologique Microfilm™ EBEc is intended to provide a rapid and easy-to-use method for simultaneous enumeration of Enterobacteriaceae and E. coli on foods and environmental surfaces. Methods: This study evaluated the performance of Microfilm™ EBEc against ISO methods (ISO 21528-2:2017 for Enterobacteriaceae and ISO 16649-2: 2001 for E. coli) in 20 food matrixes and two environmental surfaces. Inclusivity, exclusivity, lot-to-lot reproducibility, ruggedness and stability studies were also performed on Microfilm™ EBEc. Results No significant differences and high correlation coefficients (R2) were observed between the Microfilm™ EBEc and the corresponding ISO methods in spiked food matrixes and environmental samples. Inclusivity studies showed expected results for all the E. coli and Enterobacteriaceae strains tested. In terms of exclusivity testing, all the strains tested failed to grow on Microfilm™ EBEc. A lot-to-lot study showed no significant differences in mean difference (log10) counts among the three lots of the Microfilm™ EBEc. Ruggedness studies showed no significant differences in mean difference (log10) counts at varying incubation temperatures and times. Stability studies on the Microfilm™ EBEc showed that it is stable at 2–25°C for 12 months, and at 45°C for 6 weeks. Conclusions The results of this study indicate that the Microfilm™ EBEc is equivalent to the corresponding ISO methods for enumeration of Enterobacteriaceae and E. coli. Highlights: Microfilm™ EBEc offers a convenient and relatively fast test method for simultaneous enumeration of Enterobacteriaceae and E. coli in 24 h and has an advantage over the corresponding ISO methods that require two assays on the same sample for enumeration of Enterobacteriaceae and E. coli Gram-negative indicator groups.

Abstract:
The use of microfilm converters provides information in the field of processing, storage, transmission and presentation of information, especially in the process of control and measurement of physical quantities, as well as in the technology of manufacturing high technology products. Microfilm transducers form an equivalent output signal, which is a function of the measured quantity; their design and manufacturing technology are interrelated and highly correlated. Microfilm transducers are manufactured using microelectronic technology, in which group methods are used in the formation of a structure, which increases the reproducibility of parameters, are characterized by high sensitivity, low inertia, low power consumption, high reliability, and are combined with measuring signal processing devices. When creating microfilm converters, a structure is determined that most closely meets the requirements, design parameters, modes of manufacturing operations, the effect of operating conditions on characteristics, and optimal modes of operation. Structurally, a microfilm transducer consists of a base, an insulated structure, heat-generating and temperature-sensitive elements that provide the transmission of electrical signals, film conductors and contact pads, which provide a specified function of converting the measured value into an output signal. In microfilm converters, film thermocouples are used as thermosensitive elements, and adhesive sublayers are used in their manufacturing technology. The use of technological methods of microelectronics when creating microfilm converters can significantly improve their operational parameters.

Abstract:
The microfilm as a medium for long term preservation is still alive. Especially in archives the microfilm is part of the strategies. But also libraries are using microfilm until today – although it’s not a user-friendly media type and the access to information is very limited and uncomfortable. Examples of the German State Archives and from other countries show these strategies. Standards for microfilming are settled and well accepted. In the digital long term preservation standards are missing. The presentation will give an overview of ››Current status of analogous Long Term Preservation (examples, standards, tendencies) ››Current status of digital long term preservation (examples, tools, standards, tendencies) ››Analogous equipment ››Risk management ››Cost comparison digital vs. analogous ››Resume and practical hints

Abstract:
This thesis is a career biography, and chronicles the life and service of Stephen Clegg Rowan, an officer in the United States Navy, and his role in the larger picture of American naval history. The author has utilized mainly primary sources, including a journal kept by Rowan himself (transcribed from a microfilm copy of a handwritten journal, 900+ pages), and the Official Records of the United States military branches that were kept during the course of the Civil War. Rowan's wartime experiences and the contributions he made during the Second Seminole War, the Mexican War, and the Civil War form the framework of this paper. It also covers the interim periods, during which Rowan participated in other pursuits of the US Navy, including exploration and diplomatic ventures. It concludes with a brief overview of Rowan's accomplishments while serving in the Navy, and his family's continued military service. This thesis outlines the larger role played by the Navy in each engagement, with particular emphasis on the theaters of war in which Rowan participated (the Californian and Mexican west coast during the Mexican War, and his riverine and coastal services during the Civil War). It also examines the broader impact and influence that these experiences had on Rowan as an individual and on the navy as a whole.

Abstract:
HURDAT is the main historical archive of all tropical storms and hurricanes in the North Atlantic Basin, which includes the Caribbean Sea and Gulf of Mexico, from 1851 to the present. HURDAT is maintained and updated annually by the National Hurricane Center at Miami, Florida. Today, HURDAT is widely used by research scientists, operational hurricane forecasters, insurance companies, emergency managers and others. HURDAT contains both systematic biases and random errors. Thus, the reanalysis of HURDAT is vital. For this thesis, HURDAT is reanalyzed for the period of 1954-1963. The track and intensity of each existing tropical cyclone in HURDAT is assessed in the light of 21st century understanding and previously unrecognized tropical cyclones are detected and analyzed. The resulting changes will be recommended to the National Hurricane Center Best Track Change Committee for inclusion in HURDAT.

Abstract:
This research focuses on the microfilm collection preservation, in the reproduction laboratory of the University of Santa Maria which is part of the documentary heritage of the institution. The intention was to answer the question referring to the appropriate way of keeping safely the microfilm collection of the Laboratory Reproduction, maintaining the preserved information. The exposition to constant climatic changes, characteristic of the region, associated to dirtiness and micro-organisms can cause damage which leads to losing the stored information. The objective general was study the requirements for the correct storing of microforms, aiming the preservation and durability of the micrographic collection of the Federal University of Santa Maria, and ending with the elaboration of Manual with recommendations for the preservation of the micrographic collection. The research was defined as applicable and the approach was qualitative, which included the descriptive analysis of the study of the environment. The first step was the organization of a bibliographic study of the works referring to the subject, along with a study of the history of the Federal University of Santa Maria and all the departments involved with the reproduction laboratory. The research was structured in phases, the first had the objective to investigate the adopted practice in the laboratory referring the keeping and preservation of the cultural heritage, the data resulted into a diagnosis of the Safety Archive of the reproduction laboratory, in which it was possible to identify the preservation needs of the microform cultural heritage. On the second phase of the research, samples of the microfilms and the environment of the Safety Archive were collected. During the research some species of fungi were found in the storage cultural heritage, which is risky for the institution employees and, as well, to the microfilms, in case there are no immediate measures to solve the problem. On the third phase the temperature variation and relative humidity of the Safety Archive were followed. From the obtained date graphics were structured to indicate the different climatic variation in the microfilm storage room, therefore, the use of equipment that guarantees a stable climatic control is necessary, otherwise, the cultural heritage will be vulnerable to fungi proliferation. The research showed that the collection of microforms of the Laboratory Reproduction is contributing some actions to ensure the preservation of information. By studying and knowing the main measures which must be adopted for the preservation it was possible to elaborate the development and the structuration of a Recommendation Manual for the preservation of the micrographic heritage, contributing for the safeguarded of the documental patrimony of the Federal University Of Santa Maria.
Esta pesquisa aborda a preservação do acervo de microformas no Laboratório de Reprografia da Universidade Federal de Santa Maria, o qual faz parte do patrimônio documental da instituição. Pretendeu-se responder a problemática referente ao armazenamento de forma adequada do acervo micrográfico do Laboratório de Reprografia, garantindo a preservação da informação. A exposição às constantes alterações climáticas, características da região, associados a sujidades e microrganismos, podem danificar o suporte, perdendo toda a informação armazenada. O objetivo geral foi estudar quais os requisitos para o armazenamento correto das microformas, visando à preservação e a durabilidade do acervo micrográfico da Universidade Federal de Santa Maria, finalizando com a elaboração de um Manual com recomendações para a preservação de acervos micrográficos. A pesquisa definiu-se como aplicada e de abordagem qualitativa, sendo necessária a análise descritiva do ambiente em estudo. A medida inicial adotada para a elaboração desta pesquisa foi à organização de um estudo bibliográfico de obras referentes ao assunto, conjuntamente com um estudo da história da Universidade Federal de Santa Maria e dos departamentos envolvidos com o Laboratório de Reprografia. A pesquisa foi estruturada em etapas, sendo que a primeira teve por objetivo investigar as práticas adotadas no laboratório referente ao acondicionamento e a preservação do acervo, os dados resultaram em um diagnóstico do Arquivo de Segurança do Laboratório de Reprografia, no qual foi possível identificar as necessidades para preservação do acervo de microformas. Na segunda etapa desta pesquisa, foram coletadas amostras de material nos microfilmes e no ambiente da sala do Arquivo de Segurança. Nesta verificação foram encontradas algumas espécies de fungos no ambiente de armazenamento do acervo, que põem em risco a saúde dos servidores da instituição e o acervo de microfilmes, caso não haja medidas imediatas quanto à remoção destas espécies. Na terceira etapa houve o acompanhamento das variações de temperatura e umidade relativa na sala do Arquivo de Segurança. A partir dos dados obtidos foi possível à estruturação de gráficos que indicam as diferentes variações climáticas na sala de armazenamento dos microfilmes, logo, torna-se necessário a utilização de equipamentos que garantem um controle climático estável, caso contrário o acervo fica vulnerável a proliferação de fungos. A pesquisa evidenciou que o acervo de microformas do Laboratório de Reprografia está contribuindo com algumas ações para garantir a preservação da informação. Através do estudo e conhecimento das principais medidas que devem ser adotadas para a preservação do acervo, foi possível o desenvolvimento e a estruturação de um Manual com recomendações para a preservação de acervos micrográficos, contribuindo para salvaguarda do patrimônio documental da Universidade Federal de Santa Maria.

Abstract:
Um modelo circuital equivalente para o cálculo da função diádica de Green espectral transversal de estruturas multicamadas esféricas e planas é proposto neste trabalho. São estudadas estruturas multicamadas planas constituídas não só por meios isotrópicos, mas também por meios uniaxiais, biaxiais e quirais. Uma antena Yagi-Uda impressa é analisada via MoM para ilustrar a potencialidade do modelo circuital equivalente quando associado às ferramentas de cálculo simbólico e numérico do software Mathematica. Também são analisadas algumas topologias canônicas de antenas de microfita esféricas através do método da corrente elétrica superficial e do modelo da cavidade ressonante. Expressões para o cálculo da impedância de entrada, do campo elétrico distante irradiado, da diretividade, do fator de qualidade de meia potência e da eficiência de irradiação destas antenas são derivadas de forma analítica. Um programa que analisa e sintetiza estes irradiadores esféricos, que utiliza o modelo teórico desenvolvido, é implementado em Mathematica. Emprega-se a técnica do sistema de coordenadas global para avaliar o diagrama de irradiação de redes de antenas de microfita esféricas. Os resultados obtidos a partir do modelo de análise proposto são comparados com os dados de saída das simulações dos irradiadores no software de análise de onda completa HFSS. Por fim, são confeccionados e qualificados dois protótipos com o objetivo de validar a teoria apresentada ao longo do trabalho.

Abstract:
Ce travail de thèse ce focalise sur la croissance et la caractérisation de Nanofils (NFs) et de Microfils (µFs) de GaN. L'élaboration de telles structures est obtenue par épitaxie en phase vapeur d'organométalliques à partir de deux stratégies de croissances: l'une dite auto-organisée, réalisée sur substrat saphir, l'autre appelée sélective ou localisée, obtenue sur template GaN de polarité Ga. Quelque soit la stratégie employée, nous montrons que la croissance de structures verticales suivant l'axe c requièrent l'utilisation d'un flux de NH3 et d'un rapport V/III faible, lorsque nous les comparons avec les valeurs utilisées pour la réalisation de couches planaires de GaN. Les paramètres et les étapes de croissances ayant une influence sur le rapport d'aspect (hauteur/diamètre) sont étudiées et mises en évidence pour chacune des stratégies employées. Par ailleurs, les mécanismes de croissance ainsi que les propriétés structurales et optiques de ces objets sont caractérisés par MEB, MET, CL et µPL. En particulier, les expériences réalisées sur les µFs auto-organisés permettent d'observer et d'expliquer l'origine de la double polarité, de mettre en lueur la différence d'incorporation de dopants/d'impuretés entre les domaines Ga et N, d'identifier la présence de deux sections de propriétés électriques et optiques différentes, et de révéler la présence de deux types de résonances optiques: des Modes de galerie et des Modes de Fabry-Perot. D'autres part, nous étudions la courbure des dislocations vers les surfaces libres des NFs localisés et µFs auto-organisés, et pointons la présence de fautes d'empilement basales dans des régions de faibles dimensions.

This paper presents a theoretical and numerical analysis of the parameters of a rectangular microstrip antenna with metamaterial substrate. The metamaterial (MTM) theory was applied along with Transverse Transmission Line (LTT) method to characterize substrate quantities and obtain the general equations of the electromagnetic fields. A study on metamaterial theory was conducted to obtain the constructive parameters, which were characterized through permittivity and permeability tensors to arrive at a set of electromagnetic equations. Electromagnetic principes are used to obtained parameters such as complex resonance frequency, bandwidth and radiation pattern were then obtained. Different metamaterial and antenna configurations were simulated to miniaturize them physically and increase their bandwidth, the results of which are shown through graphics. The theoretical computational analysis of this work proved to be accurate when compared to other studies, and may be used for other metamaterial devices. Conclusions and suggestions for future work are also proposed

Abstract:
Traditional flood cooling processes can cause problems in micromachining due to the collision force between the fluid stream and the tool being greater in magnitude than the cutting forces. The traditional processes produce insufficient cooling rates and are unable to effectively evacuate chips from the cutting zone. Atomization-based cooling addresses these issues through high evaporative cooling rates, low impact forces, and the use of a high velocity air stream to clear the cutting zone of chips. This paper presents a probabilistic model to determine the thickness of a microfilm forming on a rotating cylindrical surface, such as a microturning workpiece or a microendmill, and the relative importance of system parameters on film formation. The rate of microfilm formation is dependent upon droplet losses in the tube, at the nozzle, and the scatter of the atomized spray. Droplet diameters and Weber numbers in the tube and at the cylinder were experimentally determined and modeled as lognormally distributed. Parameters investigated in this model are fluid and mist properties (surface tension and droplet size) and system parameters (delivery tube air velocity, spray air velocity, spray geometry, cylinder diameter, and cylinder rotational velocity). A maximum film thickness effect was found for the variables of delivery tube velocity, droplet diameter, and surface tension with a value for each variable that provided a thickest film. As the variables increased or decreased from that value the film thickness decreased.

Abstract:
Liquid-vapor oscillating flow and heat transfer in a vertically placed oscillating heat pipe (OHP) with a sintered particle wick structure inside are analyzed in this paper. The evaporation and condensation heat transfer coefficients are obtained by solving the microfilm evaporation and condensation on the sintered particles. The sensible heat transfer between the liquid slug and the channel wall are obtained by analytical solution or empirical correlations, depending on whether the liquid flow is laminar or turbulent. The effects of the maximum evaporation and condensation angles on the oscillatory flow, as well as sensible and latent heat transfer are analyzed.
