The interactive effects of inorganic carbon status, temperature and light on chlorosis induced by nitrogen deficiency, and the roles of Clp proteases in this process were investigated. In wild-type cultures grown in high or ambient CO(2), following transfer to media lacking combined nitrogen, phycocyanin per cell dropped primarily through dilution of the pigment through cell division, and also suf
Forskarskolorna erbjuder unika möjligheter för dig som är doktorand och postdoktor. De ordnar kurser, seminarier och workshops. Vissa erbjuder även forskningsuppdrag. Forskarskolorna fokuserar på specifika ämnen eller teman och för samman unga forskare från olika akademiska bakgrunder som har gemensamma ambitioner och intressen. De drivs ofta i nära samarbete med näringslivet, den offentliga sekto

Interest in the use of renewable raw materials for the production of various compounds that can replace fossil-based products is steadily increasing. In this study, the extraction and separation of hemicellulosic oligomers from spruce, to be used for the production of polymers such as hydrogels, was investigated. The focus of the study was on gel filtration of the solution from steam treatment of
Biomass provides the largest reduction of carbon dioxide (CO2) emission when it replaces coal, which is the dominating fuel in heat and electricity production in Poland. One means of replacing coal with biomass is to co-fire biofuels in an existing coal-fired boiler. This paper presents an analysis of the strengths and weaknesses of co-firing biofuels in Poland with respect to technical, environme
Local factors influencing the rate of diffusion of residential photovoltaic (PV) systems are insufficiently understood. This multiple-case study explored five Swedish municipalities which have had a particularly high PV density in terms of number of installations per capita, compared to other municipalities. The aim was to identify and assess local factors that could explain these relatively high
As automatic sensing and Information and Communication Technology (ICT) get cheaper, building monitoring data is easier to obtain. The abundance of data leads to new opportunities in the context of energy efficiency in buildings. This paper describes ongoing developments and first results of data-driven grey-box modelling for buildings. A Python toolbox is developed based on a Modelica library wit
This report compiles the findings of two business experiment surveys, conducted under CIRCUSOL Task 2.4. The experiments investigated customer preferences for two relatively novel market segments for circular photovoltaics, specifically (1) solar-powered charging stations for shared micro-mobility services, and (2) PV-systems for home-charging of electric vehicles. The experiments used the method
Halide perovskite solar cells (PSCs) have emerged as a transformative photovoltaic technology, achieving unprecedented power conversion efficiencies. However, the development of electron-transport materials (ETMs), particularly organic ETMs, has significantly trailed behind the rapid progress in hole-transport materials (HTMs). Among the organic ETMs, naphthalene diimide (NDI)-based systems stand
Bröstcancer är en heterogen sjukdom med varierande kliniskt förlopp och behandlingskänslighet. Val av behandling efter operation (strålning, antikroppar, endokrin och cytostatika) baseras på prognostiska (risk för återfall) och behandlingsprediktiva (val av behandling) faktorer. Cirka två av tre patienter är botade efter operation, och ändå får ca 90 % ytterligare behandling. Detta innebär att visBreast cancer is a heterogeneous disease with differences in clinical outcome and sensitivity to treatment. The choice of treatment after surgery (radiotherapy, antibodies, endocrine or chemo) is based on prognostic (risk of recurrence) and treatment predictive (choice of treatment) factors. About two thirds are cured after surgery, and still about 90% receive additional treatment. This means that
The Swedish energy sector has gone through a number of major changes over the last 15 years. In 1996, the electricity market was deregulated, and at the same time the prerequisites for district heating were changed, as the heat was now supposed to be sold at market price rather than self-cost price. In this chapter we analyse the process of market transformation in the district heating sector foll
Industriell bearbetning av råmaterial till användbara material bidrar väsentligt till klimatförändringar, energianvändning och andra hållbarhetsfrågor. För att bli hållbar måste industrin snabbt förändras och förändras längs hela leveranskedjan. Detta är särskilt utmanande för energiintensiv industri som kännetecknas av långa investeringscykler, hög kolintensitet och hög handelsintensitet och somIndustrial processing of feedstock into usable materials significantly contributes to climate change, energy use and other sustainability concerns. To become sustainable, industry needs to rapidly transform and change all along the supply chain. This is especially challenging for energy intensive industry that is characterised by long investment cycles, high carbon intensity, and high trade inten
Hydraulic balancing is key to ensure proper operation of the heating system. When the heating system is not hydraulically balanced, heat is unevenly distributed across dwellings resulting in a wide temperature spread, overheating, and consequently, wastage of energy. In this paper, we study to which extent hydraulic imbalance affects the thermal energy demand of buildings. Furthermore, key variabl
Vår forskning syftar till att förbättra hälsan för mödrar och spädbarn, både i Sverige och globalt. Vi fokuserar på att skapa jämlik tillgång till mödrahälsovård, höja vårdens kvalitet, driva innovation genom nya teknologier och stärka hälsosystem, särskilt i resursbegränsade miljöer. Kärnan i vårt arbete är att förstå hur mödrars hälsa och välbefinnande under graviditet och förlossning påverkar bOur research is dedicated to improving health outcomes for mothers and newborns, both in Sweden and globally. We focus on advancing equitable access to maternity care, enhancing the quality of maternal and newborn services, driving innovation through new technologies, and strengthening health systems, particularly in resource-limited settings. Central to our work is understanding how maternal heal
Altered microbial composition of the intestine, commonly referred to as dysbiosis, has been associated with several autoimmune diseases including primary Sjögren’s syndrome (pSS). The aims of the current study were to study the intestinal microbial balance in pSS and to identify clinical features associated with dysbiosis.
