O gênero é uma construção social, entretanto, ainda hoje ele é compreendido através de uma visão essencializadora e naturalizadora que se baseia em um aparato de saberes biológicos para reiterar a existência de um alinhamento entre gênero, sexo, prática sexual e desejo. Se enquadrar nesse alinhamento significa estar em consonância com as normas vigentes na nossa sociedade, e todos(as) aqueles(as) que fogem ou provocam nele deslocamentos são tidos(as) como inferiores e indesejáveis, não sendo reconhecidos como seres inteligíveis e estando, então, passíveis de exclusão. O objetivo principal desse estudo constitui em compreender a relação entre a construção parodística das personagens Drag Queens e a construção social dos papéis de gênero, dando prosseguimento à tentativa de desvendar as trajetórias e as compreensões sobre o gênero em pessoas que se encontram fora dos limites impostos pela lógica binária que valida apenas a existência do masculino e feminino, colocando-os como opostos e passíveis de categorização.2 Através do ato estético-político da construção da figura da Drag Queen acredita-se ser possível estar e cruzar a fronteira dos gêneros, tendo uma identidade ambígua ou indefinida e explicitando o caráter artificialmente imposto das identidades fixas, sendo um meio para mapear dispositivos que funcionem em prol da ruptura das ontologias e possibilitem outras formas de vivências que resistam às categorizações socialmente construídas, trazendo potência para a promoção de uma multiplicidade de possibilidades de existência / The term gender is a \"social construction\", however, it\'s still currently understood through an essential and naturalizing vision which is based on an apparatus of biological knowledges to reaffirm the existence of an alignment between gender, sexual orientation, sexual intercourse and desire. Fitting in with such alignment means being in consonance with actual social standards, and all those who avoid or arouse displacements are considered smaller and unwanted, not being recognized as intelligible human beings and, thus, being subject to exclusion. The main goal of this thesis consists on building a relation between the travesty/burlesque construction of the Drag Queens\' characters and the social construction of gender roles, continuing on in the attempt to unravel trajectories and understandings regarding the gender of people who find themselves outside the limits imposed by the binary logic which only validates the existence of male and female genders, placing them as opposites and eligible for categorization3. Through the aesthetic-political act of the construction of the Drag Queen\'s figure it\'s believed it\'s possible to be on and across the genders\' border, possessing an ambiguous or undefined identity and exposing the artificially imposed character of the fixed ones, therefore being a way of mapping devices that work for the rupture of ontologies and enable other ways of living which are able to stand up to socially constructed categorizations, bringing about enough power to promote the plurality of other possible existences

nÃo hà / A prÃtica drag queen diz respeito a um processo de adequaÃÃo que desloca a aparÃncia corriqueira de uma pessoa para uma outra que pode transitar entre gÃneros (masculino, feminino, polimorfo, diversos) e espÃcies (humano e animal, como à o caso de drags que se apresentam como animais e atà alienÃgenas). O presente trabalho tem por objetivo observar e participar dessa prÃtica na cidade de Fortaleza â CE com intuito de absorver seus processos de criaÃÃo, adaptaÃÃo, montagem e desmontagem. Entender as mutaÃÃes as quais essa prÃtica està sujeita, as influÃncias externas e a capacidade de adaptaÃÃo das drag queens estudadas. Usar lentes analÃticas que possibilitem enxergar as prÃticas atravÃs de uma epistemologia da performance que leve em consideraÃÃo a decolonizaÃÃo do pensamento e a apreensÃo crÃtica da tradiÃÃo cientÃfica europeia. O estudo se configura por meio de uma experiÃncia etnogrÃfica embasada no exercÃcio da descriÃÃo densa e de entrevistas pontuais. Os registros foram feitos mediante diÃrio de campo, fotografias, vÃdeos e gravador de voz. Concluiu-se que a prÃtica drag queen na cidade de Fortaleza â CE passou e passa por mudanÃas constantes no que diz respeito à tradiÃÃo e ao surgimento de novas formas de fazer drag. Formas essas impactadas pelo reality show americano RuPaulâs Drag Race e sua tendÃncia de transformaÃÃo da drag queen em um produto passÃvel de ser comercializado mundialmente atravÃs da TV. Observou-se ainda que, ademais da forte influÃncia trazida por esse reality show, o contexto local tem se mostrado resistente Ãs tentativas de suplantaÃÃo da tradiÃÃo, tendo como elementos de resistÃncia o bate- cabelo e o dialeto yorubà que se contrapÃem à forÃa histÃrica de opressÃo conhecida como colonizaÃÃo.

Orbital debris poses a serious threat to ongoing operations in space.  Recognising this threat, the European Commission has funded the three-year Technology for Self Removal (TeSeR) project with the goal of developing a standard scalable Post Mission Disposal (PMD) module to remove satellites from orbit following the completion of their mission.  As the project coordinator and key member of the TeSeR Project, Airbus Defence and Space Germany will invest significant resources in achieving this goal over the course of the project. This thesis details the initial analysis of potential PMD module designs conducted by the author during an internship within the AOCS/GNC department of Airbus Defence and Space Friedrichshafen between 1 April 2016 and 31 August 2016.  Three main concepts, drag sails, drag balloons and Electrodynamic Tethers (EDTs), were evaluated during this time with an emphasis on determining the ability of each design to permit passive attitude stabilisation of the satellite during PMD.  Following the required modification of a pre-existing MATLAB/Simulink model, several key findings were made for each device concept.  It was found that no drag sail designs investigated permitted passive aerodynamic attitude stabilisation at orbit heights above 550 km.  When deorbiting from 800 km, however, the lack of the desired and stable attitude was not found to have a significant increase on the deorbit time or the area‑time product. Drag balloon designs were predicted to be comparatively unstable and less mass efficient for deorbiting purposes, with area‑time products up to approximately 50 per cent higher than the equivalent mass drag sail designs.  In spite of this, unstable drag balloons were found to provide shorter deorbit times than stable balloons due to the contribution of the satellite body and solar array to the total frontal area of the satellite.  This indicated that attitude stabilisation is not required for satellites equipped with drag balloon devices. Modelling of bare EDTs suggested that tethers with lengths of 1000 metres or more would not permit passive attitude stabilisation at an orbit height of 800 km.  Simulation of a 500 metre EDT, however, indicated that passive attitude stabilisation can be achieved with EDT devices and proved that EDTs can generate significantly higher drag forces than aerodynamic devices while possessing a significantly lower device mass.  Following the analysis of these results, a recommendation was made for future work to be aimed at improving the EDT model used in this investigation.

Hydrodynamic drag testing was conducted for eleven different configurations of IsoTruss® lattice structures. Flow visualization of prototypical IsoTruss® wind towers was also performed using Particle Image Velocimetry instrumentation. The drag test and flow visualization specimens included 6-node and 8-node configurations, single and double-grid geometries, thick and thin member sizes, smooth and rough surface finishes, a helical-only structure, and a smaller outer diameter test specimen. Three sets of hydrodynamic drag tests were conducted in a closed-circuit water tunnel: 1) orientation drag tests, 2) water velocity drag tests, and 3) height variation drag tests. The orientation drag tests measured the hydrodynamic drag force of the IsoTruss® test specimens at five different orientations with an average water velocity of 1.43 mph (0.64 m/s). The water velocity drag tests measured the maximum drag for each IsoTruss® test specimen at water velocities ranging from 0.0 to an average 1.43 mph (0.64 m/s). Based on the average outer structure diameter of the IsoTruss® specimens, the water velocities corresponded to a Reynolds number range of 7,000 to 80,000. Based on the average member diameter, the corresponding Reynolds number spanned from 600 to 3,000. In addition, the height variation drag tests were performed by vertically extracting the IsoTruss® test specimens from the test section at four different immersed height levels, with a maximum immersed height of 7.22 in (18.1 cm). The height variation testing corresponded to a Froude number range of 0.40 to 0.90. The IsoTruss® specimens exhibited an average lower drag coefficient based on the projected cylindrical area than the smooth circular cylinder data throughout the Reynolds number and Froude number ranges. The drag coefficient based on solid member area showed no correlation when shown as a function of the solidity ratio. However, for the drag coefficient calculated from the solid member projected area, the data for all IsoTruss® test specimens collapsed to a 2nd order polynomial when presented as a function of the Froude number, with an R2 of 0.99. Conversely, no significant relationship was shown when the drag coefficient based on projected cylindrical area was plotted versus the Froude number. The hydrodynamic data was compared to aerodynamic data, and the orientation testing results were identical. The hydrodynamic data differed by an average of 17% compared to the non-dimensional aerodynamic results. The flow visualization research revealed that the velocity returned to 2% of the freestream velocity at 1.24 diameters upstream from the prototypical IsoTruss® wind tower. Likewise, the velocity returned to a maximum 4% of the freestream velocity at 0.94 diameters sidestream of the model IsoTruss® wind tower.

Drag embedment anchors (DEAs, or anchors) are used as foundations to secure mobile offshore drilling units (MODUs) in soft clay soils on the sea floor. In 2004 and 2005, Hurricanes Ivan, Katrina, and Rita caused the mooring failures of 17 mobile offshore drilling units moored with anchors. Since then, a great deal of research has been conducted regarding anchor performance and reliability. This report provides an overview of anchor research and industry practice to date, and discusses the results of two research experiments to assess anchor performance. One experiment investigated the effect that embedding anchors in the same soil path several times had on bearing force. The second experiment investigated what effect changing the direction of the horizontal load vector relative to the anchor shank had on embedded anchor bearing force. The results of these experiments suggest that remolding clay may have an effect on anchor bearing force capacity, and that repeatable results are obtainable when testing the effect of changing the direction of applied horizontal load. / text

Over the past century, resuscitation of victims of hemorrhage with crystalloid or colloid solutions has proven time and again to enhance survival. Recent animal studies have shown even further improvement if drag reducing polymers (DRPs) were added in nanomolar concentrations to these resuscitation fluids. Nevertheless, our fundamental understanding of how the microcirculation responds to hemorrhage is incomplete, as well as how properties of resuscitation fluids may modulate microvascular blood flow and tissue oxygen delivery. In the present study, we examined the systemic and microcirculatory responses to hemorrhage, as they relate to hemodynamics and oxygenation, and how resuscitation fluids modify these responses. Fourteen anesthetized, male Sprague-Dawley rats were subjected to a volume hemorrhage that reduced their blood volume by 30%. After 30 minutes of hemorrhagic hypotension, the animals were resuscitated either with a conventional colloid solution of Hespan (6% hetastarch), or Hespan plus 10 parts per million of the drag reducing polymer polyethylene oxide. A volume of either fluid equal to the shed blood volume was infused over a period of one hour. All the animals were observed for two hours following the initiation of fluid resuscitation or until they expired, with measurements made at 30-minute intervals during this time. Unlike previous studies, this study found no significant improvement in blood flow and tissue oxygenation, and no significant difference between the Control and DRP groups.
