On the influence of the supporting frame on the nuclear response of the Helium-Cooled Lithium Lead Test Blanket Module for ITER
2006
Abstract Within the European Fusion Technology Programme, very intense research activities have been promoted on the Helium-Cooled Lithium Lead (HCLL) breeding blanket concept with the specific aim of manufacturing a Test Blanket Module (TBM) to be irradiated in ITER. HCLL-TBM is foreseen to be located in an ITER equatorial port, being housed inside a proper steel-supporting frame. In particular, since that frame has been designed to provide two cavities separated by a dividing plate and HCLL-TBM is foreseen to fill just one of them, its nuclear response could vary accordingly to the filling status of the other one, unless the dividing plate is thick enough to isolate the components housed …
The Impact of Ethnicity on an Employee`s Readiness to comply with a Code of Conduct: Differences between German/Austrian and Chinese Employees
2018
The authors assess how ethnicity impacts ethical choices of an employee towards corporate compliance behaviour as part of the ethical decision making process at work. An employee faces an ethical dilemma in business situations when he/she is caught in an ethical conflict between his/her individual moral standards and a Code of Conduct, representing the moral values of the company. The authors investigate potential connections between ethnicity and individual ethical decision making. This study obtained original data to analyze the potential impact of ethnicity on employees in Germany, Austria and the PR China.
Failure analysis of normally-off GaN HEMTs under avalanche conditions
2020
Gallium nitride (GaN) high electron-mobility transistors (HEMTs) are promising devices in the power electronics field owing to their wide bandgap (WBG). However, all the potential advantages provided by their WBG require reliability improvement. In industrial applications, robustness is one of the main factors considered by circuit designers. This study focuses on the observation of the degradation behavior of the main waveforms of unclamped inductive-switching (UIS) test circuits of two different commercial GaN HEMT structures. The relevance of this study lies in the potential applications of these devices to high-voltage applications and automotive systems where they are subjected to many…
The precautionary principle and management of uncertainties in EIAs – analysis of waste incineration cases in Finland
2013
This article examines whether and how the practice of environmental impact assessments (EIAs) serves the idea of the precautionary principle. The article provides an empirical examination and description of how uncertainties and risks were dealt with in conclusive outputs of EIAs of chosen example cases of Finnish waste incineration projects. The analysis focuses on the time when several incineration projects were in the planning phase in Finland and the effects of this development were seen as being controversial. The findings of the analysis are evaluated against a legislative and theoretical framework. The challenges and strengths of the practice are identified. The article suggests that…
Refinement and validation of a comprehensive scale for measuring HR practices aimed at performance-enhancement and employee-support
2019
Abstract The purpose of this paper is to refine and validate a Human Resource practices (HRP) scale to measure employees' perceptions and test a two-tier model structured in eight practices and two bundles. In a sample of 554 employees, an EFA (Exploratory Factor Analysis) offered six factors that explained about 70% of the variance. Then, with 1647 employees (from 41 Spanish organizations), first- and second-order models were tested with Confirmatory Factor Analysis (CFA). The former encompasses eight practices. The latter grouped the practices in two bundles, one on enhancing performance and the other on supporting employees. The Cronbach's alpha, Rho coefficient (Composite Reliability Co…
‘I Got To Answer the Way I Wanted To’: Intellectual Disabilities and Participation in Technology Design Activities
2021
User involvement in technology design processes can have positive implications for the designed service, but less is known about how such participation affects people with intellectual disabilities. We explored how 13 individuals with intellectual disabilities experienced participation in the design of a transport support application. The study is based on qualitative interviews, photovoice interviews, participant observations, and Smileyometer ratings. A thematic analysis generated the following themes: a sense of pride and ownership, an experience of socialization, and a sense of empowerment. The findings suggest that participation in design activities is a primarily positive experience t…
Comparison of the environmental assessment of an identical office building with national methods
2019
The IEA EBC Annex 72 focuses on the assessment of the primary energy demand, greenhouse gas emissions and environmental impacts of buildings during production, construction, use (including repair and replacement) and end of life (dismantling), i.e. during the entire life cycle of buildings. In one of its activities, reference buildings (size, materialisation, operational energy demand, etc.) were defined on which the existing national assessment methods are applied using national (if available) databases and (national/regional) approaches. The ?be2226? office building in Lustenau, Austria was selected as one of the reference buildings. TU Graz established a BIM model and quantified the amou…
Modeling and Analysis of a New Process for Pyruvate Production
2005
Early process development is crucial for the economic and environmental performance of a final production process. A new process for the production of pyruvate is presented as a case study to show how process modeling and an analysis of the results regarding economic and environmental aspects improves the understanding of the process, its cost structure, and its environmental impact. It also enables the quantification of process improvements and the comparison of alternative designs. The model of the pyruvate production shows how strain and fermentation improvements propagate through the process and affect its economic and environmental performance. The comparison of two alternative purific…
Scaling-up processes: Patents and commercial applications
2020
There is currently a great demand for fish and seafood products. However, their high consumption produces large quantities of by-products that can be an ecological problem. That is why it is necessary to look for alternatives to revalue these products and give them a second life, thus reducing their environmental impact. In this sense, several investigations have been carried out in laboratories around the world to extract compounds from marine processing industry for the final high added-value products. Some of these compounds are collagen, omega 3 fatty acids, protein concentrates or chitin/chitosan, among others. Nevertheless, one of the critical steps for obtaining these compounds at th…
