Juliana Carvalho de Arruda Caulkins 05 December 2008 (has links) Os polihidroxialcanoatos (PHAs) são poliésteres acumulados por microrganismos como material de reserva. O conhecimento das vias bioquímicas e enzimas envolvidas na biossíntese e degradação dos PHAs é uma importante ferramenta para auxiliar na produção industrial. A linhagem Burkholderia cepacia IPT64 é capaz de acumular uma blenda composta de P(3HB) e P(3H4PE) a partir de sacarose. Este trabalho está focado em duas das principais enzimas envolvidas na biossíntese de PHAs: a b-cetotiolase (phaA) e a PHA sintase (phaC). A primeira está associada à especificidade pelo substrato, e a segunda é considerada a enzima chave na síntese de PHAs. Neste trabalho a linhagem mutante phaC foi avaliada quanto à atividade enzimática de PHB sintase, que se constatou ter sido perdida. A presença de mais de uma tiolase no genoma de B. cepacia foi detectada. A inativação do gene phaABc identificado anteriormente, bloqueou totalmente a síntese de P(3HB), e não promoveu o aumento da quantidade total de polímero. Este resultado indica que a tiolase identificada é responsável direta do acúmulo de P(3HB). Outra indicação é que não há uma competição das vias de síntese dos dois polímeros P(3HB) e P(3H4PE), já que não houve alteração na quantidade de P(3H4PE) acumulado, mesmo quando P(3HB) deixou de ser acumulado. / The polyhydroxyalkanoates (PHAs) are polyesters accumulated by microorganisms as storage compounds. Knowing the biochemistry pathway and enzymes involved in the biosynthesis and degradation of PHAs is an important tool to help industrial production. The Burkholderia cepacia IPT64 strain is able to accumulate a blend of P(3HB) and P(3H4PE) from sucrose. The focus of this work is on the two main enzymes involved in PHA biosynthesis: the b-ketothiolase (phaA) and the PHA synthase (phaC). The first one is associated with substrate specificity, and the second one is considered the key enzyme in PHA synthesis. In this work a mutant strain phaC was evaluated on its PHB synthase enzymatic activity, that was discovered to have been lost. The presence of other thiolases in the B. cepacia genome was detected. The inactivation of phaABc gene identified previously, blocked totally the P(3HB) synthesis, and didnt increase the polymer content. This result indicates that the identified thiolase is directly responsible for P(3HB) accumulation. Another indication is that the synthesis pathways of the two polymers, P(3HB) and P(3H4PE), dont compete with each other, because the content of P(3H4PE) was not altered, even when the P(3HB) was not accumulated. b-cetotiolase Burkholderia cepacia Biotecnologia Genética bacteriana PHA- Sintase PHB Polihidroxialcanoatos Polímeros biodegradáveis Burkholderia cepacia Biodegradable polymers Biotechnology Genetics bacterial PHA-synthase PHB Polyhydroxyalkanoates
92	Design jednotného vizuálního stylu výrobce traktorů. / Corporate identity of a tractor manufacturer Hopfingerová, Ivana January 2010 (has links) This diploma thesis deals with corporate identity of a tractor manufacturer. For this purpose fictive company called Haart was created. The endeavour of this corporate identity is to make an image of a reliable company which specialises in the production of high-quality agricultural machines. This is accomplished by an orange-grey colour scheme where orange stands for living (agricultural production) and grey refers to lifeless (tractor is a machine). The final corporate identity is presented next to company stationery, merchandise, orientation graphics and web page also on the tractor designed within the pre-diploma project. For advertising graphics needs typeface Haart was created. Part of this diploma project is also the creation of a design manual. It describes all elements of Haart‘s corporate identity.
93	Originální a převzatý zdroj v síti internet / Original and Assumed Sources on World Wide Web Svatý, Michal January 2011 (has links) The thesis focuses on problem of authorship of the Internet content. It considers the question whether we can analyze the artwork purely as a closed structure of the symbols or whether it is necessary to take work as a broader structure. The first part of the thesis shows the Internet in general and its specifics it as a medium. The second part is devoted to the problem of authorship. It explains traditional view of Nelson Goodman, who examined the authenticity of artwork with regard to the internal arrangement of the elements structure of the object. The third part shows the later theories inconsistent with the views of Nelson Goodman, views of different contemporary authors who present the changes of authorship aspects in the environment which is under constant development, quickly sharing ideas and resources. New theories suggest to look beyond the authorship of the artwork domain, apply broader focous. The conclusion provides a synthesis of these views.
94	Visuellt typinstrument : en metrologisk studie / Visual type instrument : a metrological study of typography Möller, Kristian January 2014 (has links) Visual Type Instrument - VTI, is a tool containing a typeface and a set of geometric calculations that generates numerical data in spreadsheets. The data is determined from the typefaces visual dimensions and is used to calculate leading, type size, margins and format. The aim is to offer, for all of those working with typography and design, a practical way to manage text, image and format in relationship to visual size. Instead of using point measurements, VTI uses a new device called Edo. An Edo is the same as one twelfth of a millimetre. This makes VTI compatible with the metric system and helps us to set text in relation to our own formats which applies namely in millimetres. VTI uses logical arithmetic and geometry that is set in an automated process, and many choices that normally postpone the working process can be excluded. Simultaneously VTI is meant to discreetly make the user aware that more settings can be activated in line with the users own development, which makes the creative flow unaffected. Using a metrics based on simple fractions, a mnemonic awareness is developed with the user and an understanding of how every detail fits together becomes more obvious. The typography becomes the key to any design choices that follows. The user becomes aware of the visual size, and in a cognitive way stimulated to recreate a font size regardless of the fonts limitations.

95	Automatic diagnosis of voltage disturbances in power distribution networks Barrera Núñez, Víctor Augusto 10 April 2012 (has links) This thesis proposes a framework for identifying the root-cause of a voltage disturbance, as well as, its source location (upstream/downstream) from the monitoring place. The framework works with three-phase voltage and current waveforms collected in radial distribution networks without distributed generation. Real-world and synthetic waveforms are used to test it. The framework involves features that are conceived based on electrical principles, and assuming some hypothesis on the analyzed phenomena. Features considered are based on waveforms and timestamp information. Multivariate analysis of variance and rule induction algorithms are applied to assess the amount of meaningful information explained by each feature, according to the root-cause of the disturbance and its source location. The obtained classification rates show that the proposed framework could be used for automatic diagnosis of voltage disturbances collected in radial distribution networks. Furthermore, the diagnostic results can be subsequently used for supporting power network operation, maintenance and planning. / En esta tesis se propone una metodología para la identificación de la localización relativa (aguas arriba/abajo) y la causa de una perturbación eléctrica. La metodología utiliza las ondas trifásicas de tensión y de corriente registradas en redes de distribución radial sin presencia de generación distribuida. La metodología es validada utilizando perturbaciones eléctricas reales y simuladas. La metodología involucra atributos que han sido concebidos basándose en principios eléctricos e hipótesis de acuerdo a cada uno de los fenómenos eléctricos analizados. Se propusieron atributos tanto basados en la forma de onda como en la fecha de ocurrencia de la perturbación. La cantidad de información contenida y/o explicada por cada atributo es valorada mediante la aplicación del análisis multivariante de la varianza y algoritmos de extracción automática de reglas de decisión. Los resultados de clasificación muestran que la metodología propuesta puede ser utilizada para el diagnóstico automático de perturbaciones eléctricas registradas en redes de distribución radial. Los resultados de diagnóstico pueden ser utilizados para apoyar las tareas de operación, mantenimiento y planeamiento de las redes de distribución.

96	Živý font / Live typeface Jiříček, Milan January 2012 (has links) The work describes the theoretical foundations of modern methods of creating new fonts, that is, using information technology, specifically vector programs. It also marginally shows the history of the font, Roman writing, the basic division of its compositions and describes its individual elements. The next part of the project focuses on creating digital fonts and continues with bringing it to live using algorithms and methods that can easily be processed in Matlab programming language. The method of implementation of the bringing the typeface to live is described and presentation of the generated results are then shown in few examples. Attention is also paid to the coordinates system, which is very important to solve geometric transformations, and two-dimensional vector graphics, which are widely used in the design and to render the fonts. Bézier curves and cubic Bézier curves are described in further detail along with vector graphics rasterization. One part of this text describes very important de Casteljau algorithm. The last chapter focuses on implementation in Matlab programming language, the creation of curves, that means single font characters, and the ways of how the algorithm works with transformations. Some sample images showing transformations using different input arguments are displayed in this section as well. There is evaluation of the contribution of this application and the possibilities of further expansion at the end.

99	Tvorba písma OpenType volně dostupnými softwarovými prostředky / Making OpenType fonts with free software Bednár, Peter January 2011 (has links) In thesis themes of typography and computer font of OpenType format is described in details. At the beginning attention is paid to historical development of typeface, where stress is laid mainly on development of Roman and white letter with their characteristics. Having presented basis of typography work is concentrated on topic of digital font with emphasis on possibilities of OpenType format. Further its characteristics and advantages were listed compared to another formats and it was evaluated as format appropriate also for creating font in education process. Letterspacing and kerning were mentioned between basic graphical modifications in creating fonts. In theoretical part of the thesis they were examined in available programs designed for creating font in OpenType format. Except free available means into summary were included also commercial types due to absence of more advanced instruments and functions with free available applications. In evaluation was found that the most convenient for education is Fontlab Fontographer commercial program, free Type lite and Fontforge indicated for Open-source platform. Practical part of the thesis is focused on two chosen programs for creating main font characteristics. The goal was to detect if it is possible to reach identical results when using both programs. Fontographer program enabled to use wide tool palette dedicated to vector graphic processing by means of Adobe Illustrator similar instrument. In the case of Type lite program there were rather less instruments, what is sufficient for elementary work and familiarization with creating of digital typeface. Freeware shortage is basic absence of kerning, spacing or hinting functions. Comparing program possibilities, it falls that freeware programs based on OS Windows with their functionality are sufficient only for entry level users. The best option within free available programs is Fontforge for OS Linux which supports mentioned typographic functions. Fontographer was recommended for teaching of basic characteristics of OpenType font format. Another goal of the thesis was creating of recommended work procedure for creating basic characteristics of OpenType font for students, that is enclosed at the end of the thesis.
