Evacuation experiments in a smoke filled tunnel

Evacuation experiments were performed to investigate the walking speed and the behaviour in smoke filled road tunnels. Three types of wayguidance systems, namely flashing lights, rows of flashing lights and floor markings, were tested in the experiments. A thermal imaging infrared camera was used to observe human behaviour during evacuation. The results show a relationship between the walking spee

Social sårbarhet utifrån ett medborgarperspektiv.

När extraordinära händelser inträffar, handlar de akuta insatserna för de drabbade om livräddning och akutsjukvård. Annan praktisk hjälp t.ex. att åtgärda vattenförsörjning och återställa infrastruktur ingår i kommunernas och andra myndigheters insatser. Sedan slutet av 1980-talet har även det psykologiska och sociala stödet uppmärksammats. I samband med s.k. Kistaolyckan 1988, då skolelever dog i

Regulation of photosynthesis -Cytochrome b6f in redox regulation -Two novel proteases acting on an N-terminal peptide of LHCII

Popular Abstract in Swedish I växter sker fotosyntesen i kloroplasten. Vid fotosyntes omvandlas vatten och koldioxid, med hjälp av solljus, till energirika molekyler. Dessa molekyler används dels för att bygga upp andra viktiga molekyler i växten men också för att växten skall kunna utföra kontrollerade kemiska reaktioner. En viktig del i fotosyntesen är själva ljusinsamlandet. Ljusinsamlandet skeIn higher plants photosynthesis takes place in the chloroplast. This work focuses on two different processes that effects photosynthesis. Firstly, we studied the events occurring prior to the phosphorylation of LHCII. Secondly, we also studied two novel proteases, with the potential to degrade LHCII. In oxygenic photosynthesis two different photosystems partake in the gathering of light, PSI and

A Two-Front Battle. On the Justification of Empirical Beliefs.

Popular Abstract in Swedish I dag konfronterar människor en större mångfald än någonsin. Begreppssystem av olika struktur och innehåll utmanar föreställningen om universell kunskap och skapar spänning mellan olika kulturella och lingvistiska kommuniteter. Denna bok argumenterar för att det sätt på vilket vi rättfärdigar våra trosföreställningar har implikationer för det meningsfulla i att söka uniThe question of what justifies empirical beliefs is traditionally answered either by reference to basic empirical beliefs that receive justification from something outside of the epistemic subject’s conceptual sphere or by reference to justification through coherence, in the sense that empirical beliefs are justified through their semantic relations to other beliefs. Typical of both kinds of answe

Relaxed Optimal Control of Piecewise Linear Systems

This paper applies a dynamic programming relaxation methodpreviously proposed by the authors to optimal control of piecewise linearsystems. The method gives an algorithm to find a sub-optimal valuefunction and control law within a user-specified distance from theoptimal solution. For computational reasons, the value function usedin this paper is piecewise quadratic and continuous. It cannot, ingen

Ethylene dissociation on flat and stepped Ni(111): A combined STM and DFT study

The dissociative adsorption of ethylene (C2H4) on Ni(1 1 1) was studied by scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. The STM studies reveal that ethylene decomposes exclusively at the step edges at room temperature. However, the step edge sites are poisoned by the reaction products and thus only a small brim of decomposed ethylene is formed. At 500 K dec

The impossibility of an ethical consumer

The thesis of this article is that the notion of an ethical food consumer is untenable unless it is coupled with a conception of food citizenship. The main arguments delivered against the notion of ethical food consumption are that consumption does not take the operations of moral psychology into account, nor afford means to tackle structural problems inherent in the relation between consumer and

Photoreceptors in experimental retinal cell transplants

Popular Abstract in Swedish Näthinnan (retina) spelar en central roll för vår förmåga att se. Den sitter längst bak i ögat och precis på samma sätt som objektivet i en kamera fokuserar en bild på filmen, fokuserar ögats "objektiv", dvs. hornhinnan och linsen, en bild på näthinnan. Denna bild, bestående av ljus av olika färg och intensitet, omvandlas av näthinnan till elektriska nervsignaler som skThe main objective of this thesis was to investigate the fate of photoreceptor cells when using different strategies for retinal cell transplantation. Comparing transplantation of fragments of embryonic retina with cell suspensions of the same tissue we found that transplantation of fragments of embryonic retina result in mature transplants with a higher degree of cellular organization than transp

The Escalation of Hostilities in Manchuria, 1945-47: A Study of Strategic Realities and Normative Guidelines in Military Conflict in the Context of the Chinese Civil War

This dissertation is a revisionist study of the early stages of the Chinese Civil War with a focus on the conflict in the Manchurian theatre. The military operations in Manchuria during the late 1940s were pivotal to the outcome of the Chinese Civil War, which in turn determined the political landscape of contemporary China. Clarifying the strategies employed by both sides, this study advances bey

Globalization Theory, Technological Discourses and Gendered Work – The Case of New Information Technology in Indian Banking

This article is based on a research in the project "The Employment Effects of Computer- Based Technologies in the Office-Service Sector of Developing Countries: a Comparative Study of Banking in India, Malaysia and Singapore", supported by SAREC (Swedish Agency for Research Cooperation with Developing Countries). At the time of this study (1987 to 1990) , Indian bank management was in the process

Tre städer, två broar och ett museum : minne, politik och världsarv i Bosnien och Hercegovina

The thesis deals with ritual remembrance ceremonies enacted in the three towns of Mostar, Jajce and Višegrad in BiH. The Old Bridge in Mostar, the Bridge over the Drina in Višegrad and the AVNOJ Museum in Jajce all carry a material presence that influences everyday life in these localities. Through ethnographic fieldwork, insights into local practices in relation to those World Heritage Sites are

New Challenges for Participation in Participatory Design in Family, Clinical and Other Asymmetrical, Non-work Settings

Participatory design (PD) has taken as its ideal that designers and users should engage in an equal language game. When we apply PD in contexts where some of the users involved are weak, ill, or have impairments, this assumed equality can no longer be an ideal. The workshop explores new ideals for participatory design in non-work settings with highly heterogeneous user constellations.
