Orientador: Antonio Leão Castilho / Resumo: Os siriboias são crustáceos pertencentes à ordem Stomatopoda e conhecidos pelo segundo toracópode modificado em garra raptorial, capaz de golpear e quebrar conchas de moluscos, e capturar suas presas. Podem ser separados em dois grupos de acordo com a morfologia das garras: o grupo esmagador, que desfere golpes em sua presa similares a socos de alta potência, e o outro grupo, perfurador, que perfura a presa com as projeções pontiagudas localizadas no dáctilo, último segmento da garra. Existem frequentes relatos anedóticos sobre acidentes em humanos causados por esses crustáceos, mas as informações são imprecisas e muitas vezes o animal não é corretamente identificado pelas vítimas. Este estudo apresenta o relato de 23 pescadores de Ubatuba - São Paulo, que afirmam considerar o siriboia perigoso e que evitam contato direto por conhecerem o risco que o animal oferece, e que os acidentes costumam acontecer com pessoas pouco familiarizadas com o crustáceo. Inclui um relato de lesão causada pelo urópode, informação não documentada anteriormente, e quatro relatos documentados de lesões causadas pelas garras em seres humanos. O estudo resultou ainda em um material informativo sobre os siriboias e prevenção dos acidentes. / Abstract: Siriboias are crustaceans belonging to the order Stomatopoda that are known for the second thoracopods modified to raptorial claws, capable of striking and breaking shells of molluscs and capturing their prey. They can be classified in two groups according to the morphology of the claws: the smasher group, which strikes its prey similar to high-powered punches, and the spearer, which pierces the prey with pointed projections located in the dactyl, last segment of the claw. There are frequent anedoctal reports of human injuries caused by these crustaceans, but the information is inaccurate and often the animal is not correctly identified by the victims. This study presents tertimony of 23 fishermen from Ubatuba - São Paulo, which claim to consider the siriboia as dangerous animals and avoid direct contact, due to know the risk offered. The injuries usually happen in people unfamiliar with the crustacean. It includes one report of an injury caused by the uropod, previously undocumented information, and four documented reports of human injuries caused by the claws. The study proposes informative material about the siriboias and the prevention of injuries. / Mestre

Climate change is one of the most important factor determining species ranges. In Europe there is now evidence for northward areal expansion in many Mediterranean insects including the praying mantis (Mantis religiosa). This species is the only representative of the order Mantodea inhabiting central Europe. The northern edge of the species distribution currently reaches latitude 53ř North. Although, the praying mantis is well known insect there is not enough evidence about its phylogeography. In this work three mitochondrial genes (COI, COII, Cyt b) were selected for phylogenetic study. Results indicate three statistically supported distinct lineages in Europe: Eastern European, Central European and Western European. Presumably these lineages are consistent with isolation during the last glacial and re-colonization from glacial refugia. Reduced haplotype diversity on the northern edge suggests currently established populations at the northern distribution border. To validate mtDNA results it was also considered four microsatellite loci. Due to different type of inheritance mtDNA and nuclear DNA it is possible to compare two independent genetic datasets. Microsatellite analysis confirmed results obtained on mitochondrial data. Three major genetic clusters were found: east, west and central. Spatial...

This thesis describes implementation process of issue tracking systém in company Audatex Systems s.r.o. An analysis of company's processes has been performed and ideal state after implementation is proposed. The implemented system is going to be used not only for software defect tracking, but also for company's other needs like project management and internal communication. Output of company's analysis is a list of requirements for said system and a tender is performed -- along with setting up of test environments. Process of implementation and configuration is described along with experience from implementation proces. Each of shotlisted applications is configured for company's specific needs and is evaluated with an evaluation systém, that has been created for this specific tender. Situation after implementation is descibed in conclusion of this thesis. Main benefit of this thesis lies in comparision of applications and presenting their configurations for company's needs. Two free solutions are compared along with a comercial one. In conclusion this thesis answers a question, whether a comercial solution is really needed for this specific case.

<p> There is a current interest in exploring novel microstructural architectures that take advantage of the response of independent phases. Current guidelines in materials design are not just based on changing the properties of the different phases but also on modifying its base architecture. Hence, the mechanical behavior of composite materials can be adjusted by designing microstructures that alternate stiff and flexible constituents, combined with well-designed architectures. One source of inspiration to achieve these designs is Nature, where biologically mineralized composites can be taken as an example for the design of next-generation structural materials due to their low density, high-strength, and toughness currently unmatched by engineering technologies.</p><p><br></p> <p>The present work focuses on the modeling of biologically inspired composites, where the source of inspiration is the dactyl club of the Stomatopod. Particularly, we built computational models for different regions of the dactyl club, namely: periodic and impact regions. Thus, this research aimed to analyze the effect of microstructure present in the impact and periodic regions in the impact resistance associated with the materials present in the appendage of stomatopods. The main contributions of this work are twofold. First, we built a model that helped to study wave propagation in the periodic region. This helped to identify possible bandgaps and their influence on the wave propagation through the material. Later on, we extended what we learned from this material to study the bandgap tuning in bioinspired composites. Second, we helped to unveil new microstructural features in the impact region of the dactyl club. Specifically, the sinusoidally helicoidal composite and bicontinuous particulate layer. For these, structural features we developed finite element models to understand their mechanical behavior.</p><p><br></p> <p>The results in this work help to elucidate some new microstructures and present some guidelines in the design of architectured materials. By combining the current synthesis and advanced manufacturing methods with design elements from these biological structures we can realize potential blueprints for a new generation of advanced materials with a broad range of applications. Some of the possible applications include impact- and vibration-resistant coatings for buildings, body armors, aircraft, and automobiles, as well as in abrasion- and impact-resistant wind turbines.</p><br>
