Emancipation in the net : theatre spectators and the "agency" of network
No full textIn a lecture given during the 49th Counterpoint Review of Small Theatrical Forms in Szczecin, Meike Wagner focuses on the emancipation of the theater viewer and the “agency of the Web.” The author's point of departure are some of Jacques Rancière's theses concerning the viewer as a “storyteller” and a “translator,” as well as a theory of the Internet by Bruno Latour. Using these concepts, Wagner performs an insightful analysis of the audience protests at Covent Garden in 1809 (the Old Price Riots) and the Situation Rooms project (2013) by the Rimini Protokoll group. The author considers the course and efficiency of the emancipation process in institutionalized theaters open to this sort of initiative, or the contrary, those which block the viewers' striving toward freedom

Reuse of scrap wood: in a building product
No full textClimate is changing. The average temperature on earth is rising due to excessive emissions of greenhouse gasses such as CO2. In the meantime the economy is a linear economy where a produced from exhaustive materials are consumed and turned into waste. In order to fight climate change and exhaust the earth less the greenhouse gas emissions need to decrease and less waste needs to be produced. The government has set goals to have a circular economy by 2050. A circular economy means the elimination of waste, instead all materials are reused and recycled to its final potential and new materials come from renewable sources.One commonly used renewable material in the built in environment is wood. Besides, wood sequesters CO2, has a low environmental impact and can be reused and recycled. When more wood is used and forests keep growing, more CO2 is sequestered, especially when it is substituted for product that emit a lot of CO2. Wood can so contribute to the overall decrease in CO2 emissions.But at the moment there is also a huge waste production of wood, with a annually production of 1,8 Mton waste wood, of which 435 kton is scrap wood (waste wood from the construction and demolition industry) (Sloopcheck, 2021). Most is incinerated or otherwise recycled. Only a small portion is reused. In order to contribute to the circular economy goals scrap wood should therefore be reused and recycled. This thesis aims to research why the portion of reusing scrap wood is so small and tries to find a suitable building product to show that scrap wood can and should be reused. The suitable building product is CLT, due to the used lamellae consisting of varying dimensions, mechanical properties and possibly wood species. This research shows that scrap wood can be implemented into scrap wood, although the portion of scrap wood into a panel depends on the availability of certain required properties. The substitution of scrap wood in CLT panels always results in extra CO2 savings, and therefore the reuse of scrap wood into CLT panels can contribute to reducing CO2 emissions.Architecture, Urbanism and Building Sciences | Building Technology | Sustainable Desig
Designing SeaBubble docks: A handbook for guidance on the design process for a SeaBubble dock
No full textThe project that is performed is for the master thesis of the master study ‘Integrated Product Design’ at the faculty of Industrial Design Engineering at the TU Delft. The final product is a handbook that functions as a tool to create a dock for SeaBubbles, and it is developed for the company Advier. The process started with exploring the scope. The scope can be split up in three directions: the business direction in which the company Advier and its stakeholders is analysed. It becomes clear that Advier will give the handbook to a design agency that will create the actual dock design. The second direction is the analysis of the location. The network is situated in the area of Dordrecht, also known as Drechtsteden. The effect of the weather and tide on this area is analysed and the conclusion is drawn that the design of the dock must deal with changing water levels. The third direction focuses on the SeaBubble, in which the SeaBubble for seven passengers and twelve passengers are presented. The reservation system is mapped out and shows that the SeaBubble will define its route on the demand, in between it is possible that the SeaBubble will change its route. This has a large impact on the passenger journey. In the passenger journey, two types of passengers are presented: a prepared and an unprepared passenger. The prepared passenger has bought a ticket at home, while the unprepared passenger must buy a ticket at the dock. From this point in the process, the focus will be on the experience of the passenger. By creating a building that fulfils the needs of the passenger when the passenger is being guided, is waiting, and is boarding, the experience of the passenger will be good. The next part that is being analysed is the elements that is needed for guiding, waiting and boarding. For guiding, first the crowd flow is analysed. Based on this crowd flow, a general layout of the building is created for the location of ticket vending machines, waiting areas and potential one-way systems. Secondly, the needed information is analysed and tested in an online 3D environment. The location and the initial way of communication for several information elements is determined. For waiting, literature is analysed, and people are interviewed and observed. The passengers will find distraction on a smartphone or while enjoying the view, having a seat is preferred. For creating a comfortable boarding experience, two supports are needed in an area with even floor and no gaps. By getting inspired from the results, different configurations of docks were created. By determining the principles behind the configurations, the design choices are mapped out. These design choices are structured with a morphological map and explained in the handbook, which is the final product of this master thesis. After finalising the handbook, interviews were held with the client and an architect to evaluate the final product.Integrated Product Desig
Future Greenland Melt on Multi-Century and Multi-Millennial Time Scales assessed with the Community Ice Sheet Model version 2.1
No full textThe Greenland Ice Sheet is the world’s second largest ice sheet, storing an equivalent of 7.3 meters of sea level rise. Due to climate change, the Greenland ice sheet is currently losing mass at an accelerated rate. Ice sheet models are used to project long term melt of the ice sheet, which are often forced by output from climate models. Most of the multi-millennium time scale ice sheet simulations conducted in the past used SMB calculations based on empirical relationships between melt and temperature (Positive-Degree Day schemes). In this thesis, I address the question of the future evolution of the Greenland ice sheet by means of an ice sheet model forced with an elevation dependent SMB field that accounts for the energy available for melt. This work focuses on key variables such as ice thickness, ice area, velocity and contribution to eustatic sea level rise, and assesses the reversibility of the mass loss. For this thesis, I performed uncoupled CISM2.1 simulations which were forced by the elevation- SMB field from a coupled CESM-CISM simulation. The coupled simulation used to force the ice sheet has a length of 160 years and a CO2 concentration that is increased with 1% per year from pre-industrial levels and capped at 4 times CO2. Time segments with 2x, 3x and 4x pre-industrial CO2 concentrations of this CESM-CISM run were used to force the ice sheet on multi-millennium time-scales. In addition, a Recovery from 4x CO2 was conducted in which the pre-industrial forcing from a coupled CESM-CISM simulation is re-introduced after 55% mass loss. The 2x, 3x and 4x CO2 scenarios resulted in a cumulative sea level rise of 0.49 m, 3.0 m, and 8.2 m by year 4,000. The 2x CO2 scenario resulted in limited retreat and stability within 4,000 years. No stability of the ice sheet was attained by year 8,000 in the 3x CO2 simulation, with a final Mass Balance of -108.8 Gt/yr (0.30 ± mm/yr). The 4x CO2 simulation resulted in the complete deglaciation of the ice sheet within 3,000 years. Despite the lower initial topography compared to the pre-industrial ice sheet, the Recovery from 4x CO2 simulation resulted into expansion of the ice sheet. Within 4,000 years, the mass increased from 46% to 67% relative to the pre-industrial ice sheet.Geoscience and Remote Sensin
Sustainable endoscopy: Redesigning the polyp trap
No full textThis project aims to reduce the environmental impact of an endoscopic product, the Polyp trap. The polyp trap is a single use device, that is used during endoscopy to catch removed polyps. Endoscopy is a department that has a relatively high reliance on single-use devices. This is one of the reasons why endoscopy has a high carbon footprint. Through observations in hospitals, literature and product research, the context of endoscopy, the polyp trap and other single-use devices are analysed. Additionally, circular frameworks and strategies specific to the medical context were explored, to identify circular opportunities for the polyp trap. A fast-track LCA of the current polyp trap is used to estimate its current environmental impact and analyse how interventions in design, function or material could influence its carbon footprint. The insights from this research are used to generate ideas aimed at decreasing the polyp traps environmental impact. The resulting idea directions are presented to various healthcare professionals, such as nurses and infection prevention specialists during interviews. During these interviews, opportunities and risks for the redesign are discussed. Insights from the interviews are used to further develop the idea direction into the final design.The final design consists of two concepts: The first concept is more conceptual, and reduces its impact by using some components for a longer amount of time; one day rather than per patient. The second concept is more traditional, and decreases its CF through minimising the required amount of material, leading to a smaller design that uses lower-impact materials. The environmental footprint of the final concepts is evaluated with a fast-track LCA.Integrated Product Desig
Das Thema “Altern” in Arno Geigers Roman «Alles über Sally»
No full textAlles über Sally (All about Sally) is the fifth novel of the successful Austrian author Arno Geiger. While it was both praised and criticized for being a contemporary adaption of the adultery novel, little importance was attached to the theme of ageing, which pervades the whole novel. Moreover, adulterous female characters over fifty are rare in contemporary German literature. Given these premises, this essay examines the composition of the ageing characters in the novel and provides a discussion of the social construction of images of ageing
3D Printing Metal Spare Parts On-board: The Implementation of Additive Manufacturing on-board Heerema Vessels
No full textIn this Master Thesis the potential of Additive Manufacturing on-board vessels of Heerema Marine Contractors is looked into, with the goal to design a recommendation for implementing this technology. Heerema is an offshore construction company that is intrinsically motivated to improve their sustainability. They transport, install and remove all types of offshore facilities. All Heerema vessels have a warehouse on-board, containing spare parts. Spare parts are parts in-stock that will be used to maintain the vessel or execute projects. In total the warehouse contains 300.000 parts, with an average value of 13.000.000 US$. The total weight of the stored material is 1.400.000 kg. If a needed spare part is not in-stock, it is ordered and brought to the vessel. Both actions take up a lot of time and could risk a project being stopped, which influences the economic pillar of the Triple Bottom Line consisting of people, planet and profit. Having this many parts on-board, and always ordering a ‘new part’ when something breaks, is not seen as a sustainable project execution. Especially taking into account the possibility of repairing. Next to that, extra transports or air freights are needed to get parts on-board, which influences the sustainable pillar of the Triple Bottom Line. In some cases, parts used to be produced by suppliers that do not exist anymore, which makes it hard to order new ones or obligated to purchase packages. The preferred situation for Heerema would be to use Additive Manufacturing as an additional production method for spare parts. For the implementation of this technology, a sufficient quality of the printed parts is desired. Sufficiency for critical parts has to be qualified by external certification organizations. Sufficiency for non-critical parts is reached once it functions within the used application. Next to the quality of the prints, the time it takes to print a part is important. Both quality and time depend on the performance of the 3D printer, which will influence the adoption of the crew. The preferred situation can be seen as the goal Heerema if aiming for. To reach this goal, a Roadmap is recommended. This Roadmap is designed as being the most suitable way of implementing and using 3D printing on-board of their vessels. The Roadmap is based on three different phases: The Research phase, The Printing phase and The Opportunities phase. Within these phases, the printing phase exists of two sub-phases: a plastic and a metal print phase. Each printing phase exists of a testing phase, a limited use phase and an expansion phase. The transition from one phase to another is based on a stepwise approach to lower the risks that could occur while implementing a complex innovation. The stepwise approach is based on the level of trust among the vessel crew towards the level of complexity of the implemented innovation. The conducted research supports the proposed solution that leads to the preferred situation. The solution is assessed according the three aspects of the Industrial Design Engineering domain: Technology, Human Values and Business.The solution is shown to be feasible due to the chosen hardware, the study on printable spare parts, 3D print studies and mechanical tests at the TU Delft.Additionally, the solution is shown to be viable due to relative low investment costs, a decrease in man-hours and transports and a waste reduction based on Value Stream Mapping. Also, the solution is shown to be desirable due to the collaboration with current users, a promising partnership with Layertec and the fit with the sustainability aims of Heerema. The thesis is enclosed by mentioning the research limitations, reflections, recommendations and further research for Heerema.Integrated Product Desig
Meligethes (Odontogethes) scrobescens Chen, Lin, Huang & Yang 2015
No full textMeligethes (Odontogethes) scrobescens Chen, Lin, Huang & Yang, 2015 (Figs. 22, 34– 35) Taxonomic notes. A single female specimen almost certainly belonging to this uncommon and recently described, potentially endemic species to Sichuan (Chen et al. 2015), was recently collected by the author PA (July 2015) by sweeping in a locality of northern Sichuan (Jiuzhaigou Valley; Nanping area, bushy area above the village of Zhangzha, 2200 m a.s.l., 22.vii. 2015). Although no dissected female specimens of the type series of M. scrobescens that are positively associated with males are now available for study, we describe herein the unknown female genitalia (ovipositor) of this taxon (Fig. 22), based on this isolated specimen. The ovipositor of this species is peculiarly shaped (Fig. 22), with subapical portion abruptly widened and bearing a minute but distinct U-shaped excision distad, curiously similar to the shape of ovipositors known to occur in certain W-Asiatic species of the genus Brachyleptus Motschulsky, 1845 (Kateretidae; Audisio 1989, 1993). Ratio STLE / DSIA ≈ 0.14; ratio STLE / CGOW ≈ 0.05; ratio GONL / CGOW ≈ 1.75. Basal portions of gonocoxites transverse, their laterally directed apices bluntly pointed. Ratio OVPL / GONL ≈ 2.41. Based on available external and genitalic characters, M. scrobescens is probably related to M. luteoornatus Audisio, Sabatelli & Jelínek, 2015 and to other members of the recently defined (Audisio et al. 2015) Meligeth es (Odontogethes) bourdilloni/chinensis group, markedly differing from all known species by the peculiar shape of the ovipositor in females and the median lobe of the aedeagus in males.Published as part of Liu, Meike, Yang, Xingke, Huang, Min, Jelínek, Josef & Audisio, Paolo, 2016, Four new species of Meligethes Stephens from China and additional data on other species of the genus (Coleoptera: Nitidulidae: Meligethinae), pp. 101-116 in Zootaxa 4121 (2) on page 115, DOI: 10.11646/zootaxa.4121.2.1, http://zenodo.org/record/25979
