The paper describes the results of a research programme, carried out at the Department of Aerospace Engineering of the University of Pisa, for the assessment of the influence of plasma cutting on the physical and mechanical properties of Fe510 D1, a low carbon steel widely used in carpentry. The activity started by observing that several industries rework plasma cut edges, particularly in the case of fatigue structures, in spite of the good quality of the plasma cut edges in a fully automatic process. Obviously, reworking is very expensive and time-consuming. Comparative fatigue tests demonstrated that the fatigue resistance of plasma cut specimens in Fe510 steel was fully comparable to that of milled specimens, as the consequence of the beneficial residual stresses which formed in the plasma cut edges.

Carbon capture is getting increased attention recently due to the fact that it seems to be the only answer to decrease emissions. Gas turbines exhaust have 3–5 % concentration of CO2 which is very low to be captured by an amine carbon capture plant effectively. The amine based plants are most effective at around 10 – 15% CO2 in the flue gas. In order to increase the concentration of CO2 in the exhaust of the gas turbine, part of the exhaust gas needs to be recycled back to the air inlet. On reaching the concentration of CO2 around 10% it can be fed to the amine capture plant for effective carbon capture. A 100 kWe (plus 150 kW hot water) CHP gas turbine Turbec T100 is installed at the Low Carbon Combustion Centre of the University of Sheffield. The turbine set up will be modified to make it CO2 capture ready. The exhaust gases obtained will be piped to amine capture plant for testing capture efficiency. Preliminary calculations have been done and presented in this paper. The thermodynamic properties of CO2 are different from nitrogen and will have an effect on compressor, combustor and turbine performance. Preliminary calculations of recycle ratios and other performance based parameters have been presented in this paper. This paper also covers the aspects of turbine set up machinery which needs to be modified and what kind of modifications may be needed.

Carbon Economy

Abstract In this work, the network data envelopment analysis (DEA) model was used to divide the transformation of scientific and technological achievements in colleges and universities into two stages, which makes up for the lack of process measurement in a single DEA model. Also, the relationship between the transformation efficiency of scientific and technological achievements in universities and the development of a low-carbon economy was quantitatively analyzed. The research results show that: (1) the transformation efficiency of scientific and technological achievements of universities in China is increasing year by year and which is significantly higher in the eastern region than that in the central and western regions. (2) The efficiency of the transformation of scientific and technological achievements of the university promotes the reduction of carbon emission intensity and the development of a low-carbon economy, indicating that the improvement of the transformation efficiency of scientific and technological achievements of the university has a good role in promoting the ecological environment protection. However, compared with the developed countries, the quantity and quality of science and technology supply and ecological environment protection in China’s universities are still insufficient. In this regard, the development suggestions are put forward from the aspects of government policy guidance, professional talent cooperation and strengthening the docking between universities and industrial low-carbon economic development. The purpose of this paper is to promote the development of a low-carbon economy by improving the efficiency of scientific and technological achievements transformation in universities, to achieve the goal of ecological environment protection.

This study investigates 200 kWp roof-mounted solar photovoltaic system in a country where there is no legal, policy, and institutional framework to de-risk the solar energy market but present naturally conducive environment in the sun-drenched semi-arid country. The analysis of quantitative and qualitative data subject to interpretivist and positivist approaches paves the way to find out that the university, though created financial and environments values, has not addressed the risk associated with illiquid capital intensive investment and conventional financial metrics such as net present value, internal rate of return. Hence, it is recommended to manage the risk with four strategies including maintaining economic value added at 5% or more, leveraging the investment, and withdrawing a part of equity for reinvesting in diversified investment. The findings are significant for low carbon investors to identify opportunities and manage the risk in solar energy market. Energy engineers enable designing a system that meets the fundamentals of the business and environmental value.

To avert the upcoming crisis of climate change, significant changes on different scales and sectors are necessary. The knowledge and research of the higher education sector is an essential part in the fight against climate change already. Many universities admit the urgency of acting within their institution as well and have started to measure their impact on the environment to formulate emission-reduction goals. As part of its sustainability strategy, the University of Graz launched the Institutional Carbon Management (ICM) project to calculate its emissions via a greenhouse gas emissions inventory. In comparison to other inventories, the ICM also includes the gastronomy services on and around the campus of the University of Graz, which is also the focus of this paper. It was found that especially energy- and carbon-intensive food products such as meat and dairy contribute to the emissions of a gastronomy service. In total, the gastronomy service emissions contribute 1.1% to the total emissions inventory of the university. Although the contribution is a rather small portion, the University of Graz sees itself responsible for all its emissions and therefore also aims to gain comprehensive insights into all sub-areas of its institution to formulate validated reduction pathways. The changes to a more sustainable gastronomy and low-emission diets can therefore be seen as part of a wider change towards more environmentally friendly behaviour in general with the overall aim to meet the Paris climate goal.

The Impact

At all stages of food production and consumption, resources are utilized in an inefficient manner and at an unprecedented rate, clearly affecting urban food systems. This raises future concerns in terms of climate change, and in terms of long-term food security and availability for growing urban populations. A supply-side solution to these issues - with particular potential in megacities - is Vertical Farming (VF), a high-yield form of controlled environment agriculture with promised potential to produce fruits and vegetables within cities, ultimately reducing their resource intensity. This research builds on an Urban & Regional Planning MSc thesis conducted at the University of Amsterdam. The research aims to provide a practical guide for planners, who aim to integrate Vertical Farming into urban food planning. Through this, an indication of whether and how VF can contribute to reducing the impact of food systems in terms of anthropogenic climate change is provided, and ultimately, it helps to understand if and how VF can be up-scaled for further impact. The research utilized an abductive approach with a qualitative design, where 17 experts working in the field were interviewed. These experts represent academia, consultancy, municipal officers, entrepreneurs, and investors. The findings are particularly applicable to planning with VF in cities in and integrative manner. The findings relate to 26 separate factors, along the lines of categories developed by van Doren et al. (2018). These categories include: Measures for Low-Carbon Urban Development, Operational Arrangements, Policy Context, Market Context, Social-Cultural Context, and Natural and Built Context.

E-mail: [email protected], [email protected], [email protected] Keywords: energy landscape, periphery, urban history, urban form, Madrid Conference topics and scale: City transformations     The promotion or access to certain energy technologies has changed the humanized landscape throughout history; cities have been born around, and because of an energy source, or have been displaced in order for energy-related infrastructures to take their spot. However, and for any city from its very beginning, energy paradigm shifts have deeply altered their morphology.  Not only extraction, but especially transformation and transport of resources materializes in artefacts, often controversial and soon-to-be obsolete. This is especially patent in the ever-changing city boundaries; the fringe of ‘proximity’, where the collision between the countryside and the urban mesh embodies the relations and contradictions between urban growth, energy demand and landscape protection. In a context of growing cities (both in terms of expansion of its artificial land and in terms of energy demand), we are facing two paths which not always converge: an inevitable low carbon transition and a growing sensitivity towards ordinary landscapes. This article, within the framework of the project ‘Proximity landscapes of the city of Madrid. From the 19thC to the present’, studies the development of the city of Madrid in relation to its energy access and management, in a series of key stages: mid-19thC (before the bourgeois enlargement plan approved in 1860), early 20thC (when the introduction of electricity powered a deep urban transformation and outlaying urban cores were annexed), mid-late 20thC (when a rural exodus took place and the peripheries of Madrid grew rapidly) and today.   References Ivancic, A.

Anthropogenic greenhouse gas emissions need to be cut to limit climate change. Thus, universities, in the same way as citizens and companies, are starting to raise awareness about this issue and to take action to reduce their carbon footprint. Centrale Nantes, a French “Grande école”, initiated a low carbon transition with the calculation of the 2018 carbon footprint of the university. This report presents an individual carbon footprint estimator developed within the scope of the university, based on the new open-source French national simulator called “Nos Gestes Climat” proposed by ABC (Association Bilan Carbone (Association for the implementation of Carbon footprint assessment)) and ADEME (French Environment and Energy Management Agency). Development context and important features of the national version are described. Then, to meet university user’s expectations, feedback from a panel of testers has been collected in order to guide the declination development and promote good practices ensuring user engagement. The transparency of the data model, the accurate explanations, the variety of actions have been found to be key success factors for the development and the adoption of such a simulator. Results also suggested that users are keen to involve themselves in the university initiative to reach carbon neutrality.

UK universities have been successively declaring a climate emergency, following the University of Bristol’s lead in 2019. Universities are key actors in climate change education, and potentially progressive organisations researching, teaching and implementing low carbon futures. Using universities’ sustainability strategies, we present a secondary analysis identifying neoliberalism’s significant role in influencing universities’ sustainability policies and practices. This plays out through university boosterism where universities use their sustainability work to claim sustainability leadership, representing a form of sustainability capital to attract funding and potential students. Furthermore, we suggest a cognitive-practice gap exists between those <em>researching</em> sustainability and those <em>implementing</em> sustainability in universities. Thus, we conclude that there are inherent tensions in universities’ sustainability governance, with universities embodying contradictory sustainability discourses and advancing a form of green capital. Entrenched neoliberal ideologies present challenges for those declaring a climate emergency and how such declarations are subsequently operationalised.

Can Flecks of charcoal in soils and hearths be concentrated into a usable sample for radiocarbon dating? It is impracticable to ship large volumes of soil with low carbon content from distant sites, yet dating them may be most important. This question was informally discussed following the Wenner-Gren Conference on African Prehistory held at the University of Chicago in February, 1953, and as a result Robert J. Braidwood proposed that an experimental field laboratory be established that summer at an excavation where water and electricity were available if needed. The Department of Anthropology of the University of Chicago and the Illinois State Museum were sponsoring the excavation of a rock shelter near Modoc, Illinois, and I was invited to conduct experiments there, trying out any technics that I wished. It was hoped that these experiments would result in establishing a simple procedure that could be used in many parts of the world for procuring radiocarbon samples.
