O presente trabalho tem como objetivo avaliar a influência do efeito da corrosão no comportamento geotécnico de condutos enterrados através da utilização de ensaios em modelos reduzidos. Foram empregados diferentes padrões de corrosão, em que se variou o grau e a localização da corrosão. Os resultados do trabalho mostram as localizações mais danosas à estrutura, correlacionando resultados dos tubos corroídos com os de tubos intactos. O duto danificado desencadeou um carregamento assimétrico que deve ser considerado para a prevenção de possíveis deslocamentos. Finalmente, o trabalho avalia a influência conjunta da corrosão e da flexibilidade do conduto no comportamento mecânico das tubulações enterradas. De modo a permitir comparações para averiguar a validade do modelo laboratorial adotado, utilizaram-se simulações numéricas, que possibilitam o estudo do problema de forma mais abrangente. / This work evaluates the influence of corrosion effect on the geotechnical behavior of underground conduits. Small-scale tests were carried out on two different types of pipes, in which the degree and location of the corrosion were changed. The results show the most harmful corrosion locations relative to the intact conduits. The damaged conduits built in and located under asymmetric condition behave as if they were subjected to an asymmetric loading condition and this must be considered to the prevention of possible displacements. Finally, the work evaluates the joined influence of the corrosion and conduit\'s flexibility on the mechanical behavior of underground pipelines. To allow comparisons to inquire the validation of the adopted laboratorial model, numeric simulations were used, which enable the study of the problem considering other corrosion layouts.

The master thesis focuses on the strength calculation of piping with extra consideration given to the local effects of thermal loads. To be recognized as properly functioning, the piping is required to withstand the expected operating conditions in order to enable the continuous transport of the working fluid within the interconnected devices. It is imperative to take into consideration the variable thermal load in the area where the individual pipe branches connect into the main transmission piping. A major part of the thesis is concerned with the assessment of the expected workload influence on the most stressed parts of the system. The data are gathered by employing temperature and stress-strain analyses carried out in the ANSYS Mechanical program using the finite element method. The values based on the analyses are cross-checked with both the permitted values according to the ASME standard B31.3 Process piping and the ASME Boiler and Pressure Vessel Code stress categorization method. Since all the evaluated stresses are below their respective permissible values, the piping strength is concluded as satisfactory according to the standards.

The author of the thesis deals with the issue of the short-term and medium-term rehabilitation plan for selected sewer netwotk. Resolved area for this work is the town of Břeclav. The Contracting Authority selected the area of interest that falls within the cadastral territory of Břeclav - Poštorná. The aim of the thesis is to elaborate a short-term and medium-term strategy of remediation of a selected part of the sewerage network for the need of a recovery plan.

The main goal of the master thesis is an evaluation of a software package Smap 3D Plant Design in design of evaporation technology, specifically 3D of the pipeline network and its subsequent documentation. The thesis describes evaporation technology in general, then the evaporator testing site in Laboratory of Energy Intensive Processes in NETME Centre is presented, where pipeline network needs to be designed. In the next part a reference 3D model was created as well as a documentation using SolidWorks routing. Subsequently, an equivalent 3D model was created using Smap 3D Plant Design – Piping and a documentation was created using Smap 3D Plant Design – Isometric. Finally, these two methods of creating pipeline were compared to each other, and recommended method was chosen.

Settler colonial history underlies much of contemporary industry, including the extraction and transportation of crude oil. It presents itself in a variety of contexts; however, this disquisition applies a traditional Marxist perspective to examine how settler colonialism is present in news media representation of American Indian activists during the Dakota Access Pipeline protest. Rather than focus on the benefit of using colonized labor for financial gain, this disquisition pushes Marxism into settler colonialism in which the goal is to eliminate the Indigenous and continue to widen the gap between social classes. This research is important for two reasons. First, the media are powerful, making it the perfect vehicle to disseminate inaccurate representations of American Indians. These incorrect representations come in the form of media frames that created an altered reality for news audiences. Second, the term settler colonialism, in particular its relationship with American Indian protest, has been little studied in the American field of communication. A comparative qualitative content analysis was applied to media artifacts from the protest that occurred in North Dakota. Artifacts were discovered using a constructed week approach of two online versions of print publications—the Bismarck (ND) Tribune and the New York Times—and one digital only news site, Indian Country Today. One hundred twenty four artifacts were examined in total. Five dominant frames emerged from the analysis: blame, cultural value, water, American Indian stereotypes, and confrontation. These frames were considered dominant due to the number of coded excerpts that appeared in at least 20% of the artifacts. The frames either contribute to or resist settler colonialism based on the publication in which it appears. The Bismarck Tribune contributed the most to settler colonialism; the New York Times neither rejected nor acknowledged it while Indian Country Today resisted through recognition of America’s settler colonial past, sovereignty, and government-directed violence. The implication of this research is that elimination of the American Indian is ubiquitous in American news media. The mainstream media contributes to widening the gap between social classes, ensuring the dominant class stays in power and Indigenous issues are ignored.

The paper provides an overview of the most widely used trenchless technologies and the possibility of their utilization for laying new thermoplastic pipelines. It analyzes the static behavior of thermoplastic water pipes placed into the existing steel pipes using relining technology. The program system ANSYS is used as a tool for static solution of pipelines. Obtained results are compared with conventional approaches.

abstract: The education and criminal justice systems have developed in relation to one another, intersected through specific events, policies, practices, and discourses that have ultimately shaped the experiences and lives of children of color. Racism, white supremacy, and oppression are foundational to the United States and evident in all systems, structures, and institutions. Exploring the various contexts in which the education and criminal justice systems have developed illuminates their coalescence in contemporary United States society and more specifically, in public schools. Public schools now operate under discipline regimes that criminalize the behavior of Black and Brown children through exclusionary practices and zero-tolerance policies, surveillance and security measures, and school police. Children of color must navigate complex and interlocking systems of power in schools and the broader society that serve to criminalize, control, and incapacitate youth, effectively cementing a relationship between schools and prisons. Describing these complex and interlocking systems of power that exclude children from schools and force them into the criminal justice system as the “school-to-prison pipeline” is increasingly insufficient. The “school-prison nexus” more accurately and completely embodies the relationship between education, incarceration, and the political economy. In the United States, where capitalism reigns, the school-prison nexus serves as an economic imperative to further fuel the political economy, neoliberal globalization, and the prison-industrial complex. In both the education and criminal justice systems, Black and Brown children are commodified and exploited through the school-prison nexus as a mechanism to expand free-market capitalism. / Dissertation/Thesis / Masters Thesis Social and Cultural Pedagogy 2020
