Artemisia annua L. is a herbaceous plant native from Asia which is much used as a source of essential oil and artemisinin, a sesquiterpene lactone used as antimalarial active principle. The search in the improvement regarding the production of A. annua is intense due to the high demand for this molecule. The aim of this study was to identify the suitable planting density for a higher yield of biomass, artemisinin and essential oil, and the composition of this, and also compare the performance of three varieties of A. annua for cultivation in the Southwest region of Paraná. In order to this, an experiment was conducted in a randomized block design with four replications. Three different varieties of A. annua were used: Artemis F2, and Artemis F1 (2/39 x 5)x3M. A second experiment was conducted with Artemis F2 variety in a randomized block design with three replications. The treatments were: T1: 16.666 plants ha-1, T2: 55.555 plants ha-1, T3: 94.444 plants ha-1 and T4: 133.333 plants ha-1. The plant material of both experiments was harvested at flowering (approximately 159 days after transplantation) and dried until a constant weight in an oven with air circulation at 35 ° C. The quantification of artemisinin was performed by thin-layer chromatography and detected by densitometry. The separation and quantification of substances present in the essential oil were performed by gas chromatography with a flame ionization detector and the identification of them was performed by gas chromatography coupled to a mass spectrometer. The results were submitted to analysis of variance and Tukey's test at 5% of failure probability for qualitative variables and the regression of the analysis of variance for quantitative treatments.

Biotelemetry is an important technique with many applications in biomedical engineering and other areas. The size of the remote unit or sensor is a major challenge in this area, and, in most cases, a sensor is desired to be as small as possible. Thus, passive sensors are interesting because they allow a smaller dimensions and do not require a power source or battery, which can harm the patient in the event of leakage of its chemical content. Thus, the self-ressonant inductive sensor is a good solution since it can be built with only one component. Due to its small size, this type of sensor has a low stray capacitance, which makes its self-resonance frequency very high. In this case, the bifilar coil, devised by Nikola Tesla, can be a solution, since Tesla's idea was to increase the intrinsic capacitance of his coils. Therefore a physical understanding of the bifilar coil is necessary, since as far as is known, this approach does not exist in the literature. From an analysis of the voltage between adjacent turns, equations of the Tesla's bifilar coil were developed, allowing the prediction of the increase on the internal capacitance and consequent reduction of the resonance frequency. An equivalent electric model was also developed from this analysis. This allowed the project of bifilar coils and the calculation of the internal capacitances and self-resonance frequencies of these coils. Tests were realized in order to compare the calculated and measured self-resonance for various numbers of turns...

Português
Multiphase flows are present in many industrial activities such as in exploration, production and transportation of oil and gas, in which is common to find a mixture of oil, gas and water flowing inside pipes. In many cases this type of flow determines the efficiency and safety of the processes and equipment where they occur. In this way, experimental investigations of multiphase flow are of great value to develop new theoretical models and to validate predictions made by computer simulations, hence increasing the understanding of the flow phenomena. In this work, a new measuring electronics to operate a wire-mesh sensor (WMS) is introduced. Initially proposed for visualization of two-phase flow, the WMS performs the imaging of the phase distribution of a cross section based on the multiplexed measurement of an electrical property of the fluid in contact with the mesh grid of the sensor. With the passage of flow through the sensor, the phase mapping is realized by intrusive electrodes at high temporal and spatial resolution. To allow its use in multiphase flows, the new electronics developed in this work simultaneously measures the electrical permittivity and electrical conductivity of the media in the mesh grid. The basic idea is to activate the electrodes with a signal composed of two distinct frequencies. Besides the development of the electronics' hardware...

This research explicits the ideological character of the speeches and pratices on brazilian's banks, confronting the bank workers' speech with empirical datas about the real conditions of work in these business. The management changes are understood as technologies, and the physical transformations that happened on banks - known as banking automation - as well, both serving as instrument to consolidate the model of "flexible accumulation". While these new technologies seems to create a bigger integration of the workers on the production process, with its corporatist character, we observe a intensification on work's exploration process, evidencing that this flexibility features a stage of despoilment of capitalism's workforce. The banks strategy combines the extreme exploration of workers from outsourced business who provide services for the banks with the intensification of the banks worker's labor. These workers' speeches allow us to comprehend the contradictions of this flexible model of work's organization and the daily conflicts experienced in banks, creating huge suffering to the workers. The collected and crossed datas were analyzed in a social-historical perspective, using Marx's contribution and other Marxists authors, who says that the organizational's changes results from the class struggle in its historical dynamic.; Esta pesquisa explicita o caráter ideológico do discurso e das praticas flexíveis de gestão nos bancos brasileiros...

The Historical Organizational Memory consists of the main documents that register the trajectory of an institution. It represents the legacy of this organization, available to its stakeholders in a structured and dynamic way. The ontologies aim to make sense of the content of these repositories, using the semantic relationship of the terms that can represent the area. This work establishes the basis for proposing an ontology that serves as a reference model in the Historical Memory Organization field, promoting accurate responses from search engines and information retrieval. The universe of this research is represented by companies participating in the Permanent Forum on Knowledge Management, Communication and Memory of the Brazilian Association of Business Communication (ABERJE), which already have initiatives in Historical Organizational Memory (HOM). It identifies, among other things, whether companies use a standardized instrument of information representation, such as controlled vocabularies, taxonomies and thesauri. As a method for identification of these potential instruments adopted by the institutions used in this study, we used the exploratory research, interviews with data collection, followed by content analysis and description of the results. It is intended that this ontology will serve as a reference model for Historical Organizational Memory projects...

In this master thesis, a performance analysis of an information-theoretic location verification system using directional antennas is performed, considering a vehicular network scenario. Our goal is to develop a method using directional antennas to improve the system performance. First, a recently introduced scheme that uses a simple propagation model is studied, then it is described the modifications needed when a realistic propagation model is considered. Based on the described scheme, it is shown how the use of directional antennas can be introduced into the system, creating a new validation stage called directional verification. Numerical results are used to validate the analytical expressions, showing also the performance differences between the described systems. Using the obtained results, it is shown that the use of directional antennas increase the system performance and that, even when using only the directional verification stage, the performance is satisfactory. An analysis of the relation between the number of samples and the system's error percentage is also performed, when considered a small scale fading model.; CAPES; Nesta dissertação, o uso de antenas direcionais em sistemas de verificação de localização é analisado...

A well established and widely used in the industries of ceramics and polymers, the extrusion process has been also explored by the concrete industry. Although the industry of prefabricated structural concrete using superplasticizers, there are still no specific tests to characterize the behavior in the fresh concrete used for extrusion. Although the industry prefabricated concrete structural use superplasticizers, there're not no specific tests to characterize the behavior of the fresh concrete used for extrusion. It was observed that, even in large companies, the evaluation consists of the slump test in truncated cone and the intuitive experience of an employee to handle the concrete with a shovel manual. However the concrete cast in molds is done by extruding machines that have greater strength and consistency in application. Thus extrudability of concrete is based on the testing of "slump test" and the personal evaluation of the operator, being confirmed in a pilot batch in industrial process itself. This work was based on the manufacturing process of extruded tiles freestanding. Aiming to simulate some of the conditions of the production process, there was an adaptation of the test box-L, which was inserted in the reservoir hose vibrator housing. The test consisted in assessing the behavior of the concrete to be inserted into the reservoir from the L-box and immediately after opening the gate...

Inspired by Michel Foucault, especially in his contributions on the power relations and ethics of self-care, this research aimed to answer the following problem: how is the researcher subject constituted , in the State University of Maringá, from the device of time? The author of this work used the genealogical methodol present in Nietzsche and retaken by the French philosopher to understand the power relations through which the researcher is produced. It is important to remember that the genealogy does not presuppose immutable essences which are given a priori, because, for it, the subject is understood as the effect of a given state forces. Thus, we sought to understand the conditions and circumstances in which the researcher subject was born, developed and changed, or, in other words, we sought his empirical birth. In order to understand the formation of the researcher subject, the category of device had fundamental importance, since it served as methodological operator aiding in the analysis of discursive practices, power practices and subjectivity process. Among the various devices involved in the constitution of the researcher subject, we chose to focus on the device of time. This one was proposed as a theoretical hypothesis by the author of this work and aimed to give visibility to the field of forces in which the researcher is engendered. The analysis of this device used several and heterogeneous elements...

Is in the XVIII century that arises what Foucault will call "disciplinary society". In this,the disciplinary authority is widespread and is present in several institutions - the factory, the workshop, prison, school, etc.. At the factory, for example, the work not only fulfills the productive or psychological function. The work also aims at the production of economically useful and politically obedient subjects. It is from this analysis - the disciplinary function of work - that in this reflection, is to analyze the "nature" of the work in Foucault's theory, comprising the same as constituting subjectivities and the worker's own body, thus rejecting the notion working as a return to the human, typical nature of the Marxist tradition.; É no século XVIII que surge o que Foucault irá denominar de “sociedade disciplinar”.
