I jakten på förnyelsebara energikällor är solceller en av de mest lovande teknikerna. Idag dominerar kisel-solcellen marknaden men även den har begränsningar och därför är det motiverat att utveckla andra sorters solceller. En solcellsteknik på utvecklingsstadiet som försöker efterlikna fotosyntesen är Grätzelsolcellen. Precis som i fotosyntesen är det en färgämnesmolekyl i solcellen som ska absorIn the hunt for fossile-free energy-harvesting techniques, solar cells constitute one of the most promising techniques. Today, silicon-based solar cells are the dominant technique on the market but even the Silicon solar cell has limitations which means that there is a motivation for developing new solutions. One of those techniques is the dye-sensitized solar cell. Just as in photosynthesis, the

När ett barn är sjukt påverkas hela familjen. Syskon löper risk att få mindre uppmärksamhet av sina föräldrar, och att ta på sig ett större ansvar när föräldrarnas fokus behöver inriktas på att hantera vardagen runt barnet som är sjukt. Vi genomförde en systematisk litteraturstudie av vetenskapliga artiklar med kvantitativ ansats, för att undersöka familjeterapeutiska interventioner med fokus på sWhen a child suffers from chronic illness, the whole family becomes affected. When the parents' focus needs to be on managing everyday life around the ill child, siblings are at increased risk of receiving less attention from their parents, and to take on more responsibility. A systematic literature review with a quantitative approach was conducted to investigate family therapeutic interventio

This thesis examines multiple ARCH-family models' volatility forecasting performance on the London Bullion Market Gold price, the OMXS30, and the USD/EUR exchange rate. Further, this thesis uses two different time periods to exploit differences and similarities in the forecast accuracy among the conditional variance models. The models we examine are the ARCH, the GARCH, the IGARCH, the EGARCH,

Geografiska data är all data som är knutna till ett geografiskt läge och används inom många olika områden i samhället såsom all form av samhällsbyggnad och samhällsplanering, klimat och miljö, kultur och natur, krishantering samt transporter och logistik. För att geografiska data ska kunna användas över läns- och kommungränser samt i olika organisationer krävs ett enhetligt system och standarder fGeographic data are data that is linked to a geographic location and is used in many different areas of society, such as all types of community and community planning, climate and environment, culture and nature, crisis management, transport and logistics. In order for geographic data to be used across county and municipal boundaries as well as in different organisations, a uniform system and stan

Water scarcity can have severe implications for society; endangering human health and food security whilst also exacerbating social conflict around the world. These issues are exemplified in the case of the Ferghana Valley in Central Asia, where much of the valley suffers from water scarcity and conflicts despite having adequate water sources. This scarcity is primarily due to how water is used, m

International and national carbon reduction plans and targets have constituted the subject of a copious amount research in recent years. Concurrently, the number of cities, regions, companies and communities that have set ambitious targets for renewable energy and energy efficiency has been growing. Among these actors, rural communities in the developed world and their efforts toward the transitio

Poor survival and differentiation of grafted dopamine neurons limits the application of clinical transplantation in Parkinson’s disease. The survival of grafted dopamine neurons is only improved by a factor of 2–3 by adding neuroprotectants during tissue preparation. We used dye exclusion cell viability and electron microscopy to investigate the effects of the caspase inhibitor ac-YVAD-cmk and the

Popular Abstract in Swedish Genom att studera forna inlandsisar kan vi få en inblick i hur en inlandsis påverkar och påverkas av till exempel klimatförändringar och havsnivåvariationer i tidsperspektiv från hundratals till hundratusentals år. I Skandinavien är det framförallt spåren efter nedisningar under den senaste istiden, Weichsel-istiden, som bevarats. I den här studien fokuserar vi på ÖstIn this thesis the Weichselian glaciation history of southernmost Sweden and the southwestern Baltic Basin is discussed, with special emphasis on Middle and Late Weichselian ice advances and subsequent deglaciations. The main study area was Kriegers Flak in the southwestern Baltic Sea where pre-Late Weichselian sediments were identified. We suggest that the lowermost till on Kriegers Flak, dated t

The active participation of scientific trusts, including CISO (Centro Italiano Studi Ornitologici), in applied conservation actions plays a crucial role in addressing the challenges faced by natural and semi-natural landscapes, which are increasingly impacted by improper land-use and land-cover. This is particularly true for those landscapes where Large Infrastructures and Big Events (LIBEs) are p

The authors of this policy brief are contributors to the research project Infrastructuring Libraries in Transformation (ILIT). ILIT’s objective is to examine public libraries’ role in this era beset by social challenges such as segregation, discrimination, austerity measures, and unemployment. ILIT began conducting research in three urban communities in 2022: Malmö, Sweden; Rotterdam, the Netherla

Background: The existence of a “minority tax,” defined as the burden of extra responsibilities placed on minorities relative to non-minorities of the same position, has been documented across various fields, including and beyond medicine. This study sought to quantify the types and extent of the minority tax faced by minority orthopaedic surgeons, as well as evaluate the degree to which this work

Older and normally more low-scale buildings are from a historical and cultural perspective in need to be preserved. But these older buildings are often also perceived as contributing to more beauty-oriented values to an urban environment, so called charm. For these reasons, new building development projects should be designed in such a way that these qualities are not destroyed. This study has thr

Lattice Boltzmann method (LBM) is alternative computational method to the traditional computational fluid dynamic (CFD) methods. LBM has the ability to with straightforward computational procedure to handle the detail activity at microscale well for simulation of different transport processes. In this study the focus is on the effects of electrochemical reactions and transport processes in an anod

Objective. The aim of the study was to survey existing research about fatigue among older people with chronic non-malignant pain. Method. A structured literature review was carried out using the Medline database. The terms ‘fatigue’ and ‘tiredness’ were used synonymously. These subject headings were combined with pain. A literature search was made in 2004 and included articles back to 1995. Resu

Numerical simulations coupled with LDV experiments were carried out to investigate a slot jet issued into a cross flow, which is relevant in the film cooling of gas turbine combustors. The film cooling fluid injection from slots or holes into a cross-flow produces highly complicated flow fields. In this paper, the time-averaged Navier-Stokes equations were solved on a collocated body-fitted grid s

Abstract in UndeterminedSubject-specific finite element models have been used to predict stress-state and fracture risk in individual patients. While many studies analysed quasi-axial loading configurations, only few works simulated sideways load configurations, such as those arising in a fall. The majority among these latter directly predicted bone strength, without assessing elastic strain predi

We have reported that epidermal Langerhans cells possess an H+-extruding mechanism signalling their existence in an anaerobic environment. This study highlights the energy metabolism of human epidermis. In their habitual state the keratinocytes contain more lactate than do most other cell types. Their lactate production in vitro is vigorous and independent of oxygen and most of it is released to t

The runoff from real 3 cm thick sedum-moss roofs and from laboratory roof plots in southern Sweden is measured and analysed. Real rains and artificial storms are used for the analysis. The probability of high runoff is compared with the probability of high precipitation intensity. Intensity-duration-frequency curves for runoff are derived and it is found that the runoff of 1.5 year return period c
