Singlet fission is the spin-allowed conversion of a spin-singlet exciton into a pair of spin-triplet excitons residing on neighbouring molecules. To rationalize this phenomenon, a multiexcitonic spin-zero triplet-pair state has been hypothesized as an intermediate in singlet fission. However, the nature of the intermediate states and the underlying mechanism of ultrafast fission have not been eluc
To avoid eutrofication and excessive algal bloms it is necessary to reduce the phosphorus contents in wastewater. Previous wastewater treatment systems often have a good process for phosphorus reduction but in general not the ability to recycle the material and phosphorus for further utilisation after its use in wastewater treatment. Polonite® is a material with large content of calciumoxide wh
Aims: To describe and compare perceptions of collaboration between care providers on the part of three groups of Registered Nurses working in municipal care and having particular responsibility concerning the care of frail older people with intellectual disability (ID); and, furthermore, to investigate the presence of and compliance with guidelines for the coordination of care. Design: National su
Objective: To evaluate sick leave after meniscal repair vs arthroscopic partial meniscectomy (APM) and, for comparison, vs the general population. Method: Using Swedish register data we included all employed persons aged 19–49 years in the general population of Skåne region and identified those having had meniscus repair or APM in the period of 2005–2012. We retrieved data on sick leave during 1 y
Brain injury rehabilitation is a long and difficult process that includes training of so-called instrumental activities of daily living (IADL). This type of training involves activities like preparing meals, doing housework, grocery shopping etc. and it is often used by occupational therapists when they teach brain injury patients how to manage their daily life. A computer-generated Virtual Envir
Graphene presents unique optoelectronic properties, making it attractive for the development of a wide range of new and advanced technological applications such as high-speed photodetectors and all-optical modulators. The study and control of the generated carriers in graphene, namely their ultrafast relaxation dynamics, are of great importance for these applications. Here, we report the ultrafast
Exposure to aerosol nanoparticles has always been present in the evolution of humans, and thus has the human body developed ways of dealing with particles that enters the body. However with the emerging nanotech industry, new types of nanoparticles are being produced and used. Many of these particles have properties never seen before and this rise concern about how exposure to them might cause unw
We present an efficient, low-cost implementation of time-hopping impulse radio that fulfills the spectral mask mandated by the FCC and is suitable for high-data-rate, short-range communications. The system was proposed to the IEEE 802.15.3a group for standardization as high-datarate personal-area network (PAN). Key features are: (i) all-baseband implementation obviates the need for local oscillato
People’s obsession over objects and constantly renewing them was the initial core of the project. This led us in the direction of the fast fashion industry. The unrelenting change of trends forces the consumer to continuously update their wardrobe, while the time spans for new trends keep decreasing. The textile industry is one of the largest environmental issues of today. By focusing on outdoor e
Digitaliseringen i samhället breder ut sig i allt större omfattning. Utvecklingen öppnar upp för en mängd möjligheter men kommer även med en hel del utmaningar. Processer som tidigare varit beroende av manuella förfarande kan nu hanteras helt automatiskt. Detta gäller exempelvis möjligheten att fatta automatiserade beslut inom den offentliga förvaltningen. AI möjliggör för mer komplicerade uppgiftDigitalization in our society is rapidly extending into new areas. The development opens up for many possibilities but also brings a number of challenges. Processes that were earlier dependent on manual procedures can now be managed automatically. This can for example be carried out through automated decision-making within the public administration. For more complicated tasks AI can extend the pos
This thesis is a study of the public social life of children in an urban environment and of implementation of techniques and tools that would transform urban spaces in a typically large metropolitan city into a child friendly space. The common conception of children as the future citizen rather than as active citizens have lead to completely ignoring the needs of children during the designing proc
Bakgrund: Fotboll är en av världens största idrotter och i Sverige står fotbollen för ca en tredjedel av den samlade svenska idrottsrörelsen. Andelen damfotbollsspelare ökar ständigt. Man har sett att damfotbollsspelare löper en ökad risk för att drabbas av knäskador och då framförallt främre korsbandsskada. Denna skada är allvarlig då den innebär stora konsekvenser för både spelaren och samhället
Bakgrund: Inom läraryrket utgör stillasittandet en stor del av arbetsdagen, en riskfaktor som kan påverka den fysiska och psykiska hälsan negativt. Självskattningsfrågor är ett kostnadseffektivt sätt att skatta stillasittande. För att kunna dra tillförlitliga slutsatser gällande en persons stillasittande från självskattningsfrågor krävs det att dessa är valida. Syfte: Syftet med undersökningen var
