Development of In Vitro Three-Dimensional Microvascular Tissues

Chang, Carlos January 2008 (has links)
Microvasculatures may become damaged by a variety of acute and chronic diseases. In many cases, microvessel function is irreversibly compromised, leading to the dysfunction and even death of surrounding tissues. Currently, there are few therapies that directly address the treatment of microvascular insufficiency. Responding to this need, researchers are developing methods to fabricate in vitro blood vessels. Typical strategies include; cellular sodding within polymers and/or biopolymers, the formation of cylindrical cellular monolayers around polymer mandrels, and the modification of biocompatible surfaces for cellular adhesion. Using currently available techniques, simple, individual vessel conduits have been engineered with internal diameters down to 150μm. However, no evidence has been provided illustrating the formation of patent, interconnected microvessel networks without the aid of a host circulatory system. In response to this challenge, it is hypothesized that a novel flow-based experimental system will support the in vitro development of three-dimensional microvascular tissues. Addressing this hypothesis, the presented work focused on three specific aims: Specific Aim 1. Pattern planar in vitro three-dimensional microvasculatures. Specific Aim 2. Engineer a Dynamic In vitro Perfusion Chamber (DIP Chamber) for microvascular investigation. Specific Aim 3. In vitro perfusion of microvessel fragments within the DIP Chamber. Through the supporting experiments, directed endothelial sprouting from parent isolated microvessel fragments was achieved. In addition, patent in vitro microvessel networks were successfully developed. The presented experiments are the first to achieve these experimental results. In addition, the described experimental model will provide a unique method for future investigations of microcirculatory phenomena. Since no exogenous growth factors or cell signals were introduced into the constructs, it is believed that this system presents a physiological platform for future investigations into angiogenesis, angioadaptation, and network remodeling. Moreover, this model may offer a useful platform for vascular therapeutic testing and a foundation for future tissue engineering applications.

The merit of environmental impact assessment for civil engineers in South Africa.

Pienaar, Melanie January 2012 (has links)
Environmental Impact Assessment (EIA) has been successfully adopted in South Africa in line with international trends. A number of international scholars found that EIA offers distinct advantages to a proposed project (Bartik, 1988; Porter & van der Linde, 1995; Annandale & Taplin, 2003). The widespread successful adoption of EIA could be an indication that the benefits of conducting EIAs outweigh the potential economic loss due to delays and costs related to the EIA. However, there are negative perceptions about EIA and its influence on development. But the question is whether South African engineers are experiencing these benefits at project level? South African civil engineers are faced with the legislative requirements of EIAs on a daily basis. Through a survey of professionally registered civil engineers this research examined the merits that EIA has for civil engineers. It was found that EIA helps engineers to ensure that they have all the legal aspects of the development in place before the development starts. Furthermore EIA creates the opportunity for the engineers to design out the most significant adverse environmental impacts. It was found that since the implementation of EIA engineers are observing a shift towards more environmentally sound design alternatives. Therefore, if the EIA process is influencing engineers to review their designs from an environmental point of view, it could significantly minimise environmental impacts. According to engineers it was found that, EIA is assisting them in taking all the potential impacts of a new development into account during the design process. The engineering design normally determines the true environmental impact of a development. According to the respondents, the majority were aware of projects where the design was changed as a result of potential impacts highlighted by the EIA. It was found that for the majority of the respondents the environmental review of the design was a key component of the design process. According to the engineers that took part in the survey, they were aware of projects where the EIA improved the sustainability of the design by effecting a change to the design or to the construction materials. Since the implementation of EIA they have become more aware of, not only the life cycle, but also the sustainability of the development. EIA is therefore creating awareness about sustainability in the engineering fraternity. The engineers experienced EIA as a useful tool for improving the sustainability of the design. However, it was found that EIA also caused a significant delay in the majority of the projects where the respondents were involved. The delays were sometimes so severe that it jeopardised the economic feasibility of the projects in question. According to the respondents, the delays are mainly due to slow decision making by the competent authority. Due to this slow decision making process, the engineers blame the competent authority if they start with the construction of the project before authorisation. However, in spite of these delays, the engineers are still of the opinion that EIA is doing more good to the environment than harm to the economy. It was found that what the majority of the engineers knew about the EIA process was what they had learned from their own experience. They agreed that there was very little focus on environmental sustainability during their undergraduate studies and that EIA training during their undergraduate study would have been useful. But in spite of this, the majority of respondents did not complete any environmental short courses or post graduate studies. It was found that EIA does in fact have a positive influence on the work of civil engineers and that they experience these benefits at project level. The engineers have a positive attitude towards EIA and it is increasingly influencing their work positively. / Thesis (M. Environmental Management)--North-West University, Potchefstroom Campus, 2013.

Arctic foxes as ecosystem engineers: benefits to vegetation and collared lemmings through nutrient deposition

Gharajehdaghipoor, Tazarve 14 January 2016 (has links)
I estimated the non-trophic effects of arctic fox (Vulpes lagopus) denning activities on soil nutrient dynamics, vegetation production and quality, snow cover thickness, and their primary terrestrial prey, collared lemmings (Dicrostonyx richardsoni), near Churchill, Manitoba in April, June and August 2014. Arctic foxes increased soil inorganic nitrogen and extractable phosphorous concentration on their dens. This increase in soil nutrient levels resulted in greater vegetation quantity (measured as biomass and cover) and quality (measured as nitrogen content) on dens. Increased vegetation cover, specifically Salix sp. and Leymus mollis cover, positively affected snow cover thickness on dens by trapping blowing snow. Increased snow cover thickness made dens attractive nesting sites to collared lemmings (measured as lemming nest counts). In addition, dens with lemming nests had greater snow cover thickness compared to dens without lemming nests. Greater vegetation quantity and quality on dens could also attract lemmings to dens for winter nesting. / February 2016

Career anchors of engineers in managerial positions in the South African power utility

Sithole, Ntombizodwa 12 October 2012 (has links)
Due to the introduction of the Employment Equity Act of 1998, the structure of management in South African companies has dramatically changed. This emphasizes the need for managerial generalists, especially now where we are faced with a competitive business environment and rapid changes in technology. Edgar Schein (1978) in the (Academy of Management Journal 1996) maintains that these changes have resulted in people forming what he called “internal careers”. He described an “internal career” as a subjective sense of where one is going in one’s working life. He continued to describe the external career as something that is more about formal stages and roles, well defined by organisational policies and societal concepts regarding what an individual can expect in an occupational structure”. The complexities in the occupational environment have implications for career development, and it has obviously become crucial that people form what Edgar Schein regarded a self-concept, to be a ““career anchor” that holds a person’s internal career together even if they experience intense changes in their external career”. An individual’s “career anchor”, as defined by Schein (1978; 1985; 1990; 1993), comprises of a person’s 1) “self-perceived aptitudes and capacities; 2) basic values; and most important, 3) the evolved sense of motives and desires as they apply to the career”. Using the instrument called the Career Orientations Inventory (COI) developed by Edgar Schein, the objective of this study to systematically examine the primary career anchors of a sample of engineers in management positions at one of the utilities in South Africa. This is a quantitative study which uses a statistical analysis to substantiate engineers’ motivation for pursuing managerial positions instead of remaining specialists. The results from this study will have a major contribution in the field of Psychology and in particular, Career Psychology. / Dissertation (MCom)--University of Pretoria, 2012. / Human Resource Management / unrestricted

Výzkum využití technologie rozšířené reality při práci konstruktérů / Untersuchung des Einsatzes von Augmented-Reality-Techniken auf die Arbeitsprozesse in der Konstruktion

Holešovský, Jiří January 2018 (has links)
This diploma thesis summarizes the principles of augmented reality and the possibilities how this technology could be used in the work of designers. The thesis also describes the possibilities of realizing an augmented reality (AR) program and compares specific AR devices. The process of the designer's work is also analyzed, and concepts how AR could be used during the work process were designed. One concept of use has been implemented. It was a visual-ization of new constructed parts of autonomous robot, developed in project "FOLLOWme". The designers will use this program to detect collisions between parts and verify overall design of the robot.

From Inzhener to ITR: Russian Engineers and the First Five-Year Plan

Vidumsky, John E. January 2010 (has links)
The Russian engineering corps was almost completely transformed during the first five-year plan, which ran from 1928-1932. The purpose of this thesis is to examine the nature of that change, and the forces that drove it. In this paper, I will argue that the corps was transformed in four fundamental ways: class composition, skill level, role in production, and political orientation. This paper begins by examining the old engineering corps on the eve of the first five year plan. Specifically, it examines Russian engineers as a subgroup of the intelligentsia, and how that problematized their relationship with power. I next examine how the Soviet government forcibly reshaped the engineering corps by pressure from above, specifically by a combination of state terror and worker-promotion campaigns. These two phenomena were closely intertwined. Along with collectivization and crash industrialization, they were part of the "Cultural Revolution" that reshaped Russian society in this period. I next examine how the campaign of terror against engineers was used by Stalin and his camp for political gain on a variety of fronts. Lastly, I will examine how engineers became part of the Soviet elite after 1931. For sources, I rely especially on the correspondence between Stalin, Kaganovich, and Molotov, which was published in the Yale University Annals of Communism series. I also draw heavily on The Harvard Refugee Interview Project, memoirs, and the collected works of Joseph Stalin. / History
