The concept of circular business models has been identified as an important enabler for companies moving towards circular practices. Circular business models help to prolong lifetimes of products and parts through successive cycles of reuse, repair, remanufacturing and closing material loops. To realise economic viability and reductions in environmental impacts from innovating towards a circular b

Shortcomings of current techniques used for the intracerebral transplantation of ventral mesencephalic dopamine neurons include low graft survival, high variability, considerable implantation trauma and suboptimal graft integration. In order to overcome these limitations, we have adopted a microtransplantation approach which allows precise and reproducible implantation of ventral mesencephalon cel

Popular Abstract in Swedish Denna avhandling diskuterar hur en föreställning om enhet har präglat västerländskt politiskt tänkande om politisk gemenskap. Den visar att ett antagande om likhet, återspeglad i tid, rum, språk och rationalitet, har setts som en förutsättning för politisk gemenskap. Antagandet om likhet innebär att varje försök att utvidga gemenskapen ger upphov till nya exkluderingar This thesis argues that the Western thinking of political community has assumed the community to require a unity or unifying principle that serves as delineation. It suggests that sameness, reflected in history, space, language, or reason, has been assumed as the condition of possibility of the political community. Consequently, a particular identity is made a prerequisite for membership and vouch

A methodology was developed and tested in six case studies at four medium-sized manufacturing companies within the machine engineering industry. Existing and planned work environments and production processes were described with the aid of computer-generated pictures. The pictures were used within the framework of an action research methodology in which managers and those employees affected, toget

Wrap Your Troubles into Dreams, är ett praktikbaserat forskningsprojekt. Undersökningen berör stadsomvandlingsprocesser i Stockholmsområdet, speglade genom två politiska förhållningssätt gestaltat i staden: genomförandet av det funktionsseparerade Stockholms City (under 1960-talet) och de senaste decenniernas privatisering av stadsrummet. I forskningen har jag utgått från två platser som i motreakWrap Your Troubles into Dreams is a practice-based artistic research project. The study investigates city transformation processes in the Stockholm area, by viewing them through two political attitudes expressed in the city; the introduction of the function-separated Stockholm City area (during the 1960s) and the privatisation of urban space during the last few decades. I have based my research on

Popular Abstract in SwedishDenna avhandling studerar relationer mellan film och historia. Tesen som drivs är följande: Film utgör ett i stora delar outnyttjat historiskt källmaterial som alltid säger mer av empiriskt värde om sin produktionskontext än det gör om perioden som skildras. Denna tes bygger vidare på resonemang kring film och historia som genom åren har framlagts av företrädesvis historThe hypothesis put forward in this thesis stipulates that films always say more of empirical value about the time in which they are produced than they do about the periods they depict. The aim is not only to prove that such an idea is valid, but also that it might be transformed into a new and applicable theory in studies of film and history. Here, this is done in contextualized analyses of the pr

Dataharmonisering är en förutsättning för smarta städer, för ett mer effektivt informationsflöde i samhällsbyggnadsprocessen och för många andra tillämpningar i en stadsmiljö. Vid ett bästa tänkbart scenario kommer dataharmonisering att resultera i ett digitalt informationsflöde som inkluderar information från ett objekts hela livscykel, till exempel för byggnader, vägar och tunnlar. Alla aktörer Data harmonisation is a prerequisite for smart cities, for a more efficient information flow in the planning and building process and for many applications in the urban environment. Ideally, data harmonisation will result in a digital information flow that include information from the whole lifecycle of a feature, for example for buildings, roads and tunnels. All actors and applications involved i

A multigene phylogenetic study was carried out to test current, mostly morphology-based hypotheses on Sterrhinae phylogeny with additional material included from further geographical areas and morphologically different lineages. A maximum likelihood analysis (11 molecular markers and 7665 bp) was conducted on 76 species and 41 genera using iq-tree software. The resulting phylogenetic hypothesis is

Popular Abstract in Swedish I avhandlingen behandlas de rättsregler som kan tillämpas när banker erbjuder kunder att kommunicera via Internet och lämna betalningsinstruktioner avseende kredittransfereringar på detta sätt. Den här typen av banktjänster benämns i avhandlingen Internet Banking. Betalningar och betalningsinstruktioner är inget nytt fenomen men i avhandlingen behandlas de utifrån ett eThis thesis deals with legal issues arisen from consumer-activated payment orders, regarding credit transfers, which are initiated via the Internet under an agreement (about using Internet-services) previously entered into between the bank and the payer (or the originator). This Internet-service is in the thesis called Internet banking. More and more customers, both consumers and others, activate

The overall purpose of this paper is to contribute to the development of an internal crisis communication perspective. More precisely, we want to discuss and illuminate the need for an emergent, co-worker-oriented perspective on crises. Such a perspective implies a broader view on crises and a need to include change communication as an allied re-search field to crisis communication, and not at lea

This contribution seeks to demonstrate how recently developed 3D GIS platforms can help archeologists in relating to the original context legacy data that can be employed to digitally reconstruct the sequence of arbitrary layers as it was observed and then excavated in the end of the nineteenth century. This research has been conducted on the prehistoric cave of Stora Förvar, located on the small

Exoplanet interior modelling usually makes the assumption that the elemental abundances of a planet are identical to those of its host star. Host stellar abundances are good proxies of planetary abundances, but only for refractory elements. This is particularly true for terrestrial planets, as evidenced by the relative differences in bulk chemical composition between the Sun and the Earth and othe

In the present study the time-course of DNA fragmentation following insulin-induced hypoglycemia was examined. In situ localization of DNA breaks were studied by the terminal deoxynucleotidyl transferase-mediated biotin- deoxyuridine triphosphate nick-end labelling method, and the temporal profile of DNA-fragmentation by agarose gel electrophoresis. Cell nuclei displayed terminal deoxynucleotidyl

The main challenge in predicting structure-borne sound in wood buildings is to accurately model the vibration transmission between the source and the receiving room. Large variations in model parameters make it difficult to predict absolute vibration levels and to make conclusions regarding the relative effects of different designs. A step towards establishing reliable models is to investigate the

Electronic dynamics takes place on the attosecond timescale and can thus only be studied using a tool with attosecond temporal resolution. High harmonic generation (HHG) provides coherent attosecond pulses in the extreme ultraviolet spectral region. The work presented in this thesis focuses on generating and characterizing ultrashort femtosecond pulses and using them for HHG, together with a gatin

Tundra soils account for 50% of global stocks of soil organic carbon (SOC), and it is expected that the amplified climate warming in high latitude could cause loss of this SOC through decomposition. Decomposed SOC could become hydrologically accessible, which increase downstream dissolved organic carbon (DOC) export and subsequent carbon release to the atmosphere, constituting a positive feedback

"A brief history of sound art is, in a nutshell, a history of sonic forms of expression that throughout the twentieth century can be traced within music, the visual arts, and contemporary dance, as well as in performance art, conceptual art, and media art. Attempts to capture sound art as a detached and isolated art form or artistic phenomenon have been made, but this is definitely not the approac

The Sectra MicroDose Mammography system is based on direct photon counting (with a solid-state detector), and a substantially lower dose to the breast than when using conventional systems can be expected. In this work absorbed dose measurements have been performed for the first unit used in routine mammography screening (at the Hospital of Helsingborg, Sweden). Two European protocols on dosimetry
