Sammanfattning Detta arbete har delats in i två delar. Den första delen handlar om olika energilagringstekniker. Den andra delen handlar om att lagra egenproducerad elenergi i ett flerbostadshus. Syftet med första delen har varit att samla information om olika energilagringstekniker i en kunskapssammanställning genom att studera dess funktion, aktuella status och framtidsutsikter. Den andra delen Abstract This master thesis is divided into two parts. The first part deals with a general study of different energy storage systems. The second part deals with the possibility to store own-produced electricity from solar panels in a multifamily residential area. The purpose of the first part was to collect information about different energy storage systems in a general study, and examine their di

SiS särskilda ungdomshem är institutioner där barn och unga i behov av särskild tillsyn placeras, till största del sker detta med stöd av lagen (1990:52) med särskilda bestämmelser om vård av unga (LVU). Uppsatsen syftar till att utreda i vilken utsträckning rätten till hälsa enligt artikel 24 i Förenta nationernas konvention om barnets rättigheter (barnkonventionen), är uppfylld för flickor med SiS youth homes are institutions which provides compulsory care for young people with psychosocial problems, with legal support usually found in the act (SFS 1990:52) with special provisions on the care of young people (LVU). The purpose of the thesis is to examine whether the right to health as established in art. 24 of the UN Convention on the Rights of the Child, is respected for girls with men

Aktivt kol har identifierats som en av de mer effektiva metoderna när det kommer till att avlägsna organiska mikroföroreningar (OMF) från avloppsvatten. Aktivt kol är ett poröst material med stor ytarea som kan adsorbera andra ämnen. Det är inget som existerar naturligt utan behöver framställas. Framställningen kan ske från i princip vilket material som helst som har en hög kolhalt. En stor del avActivated carbon has been identified as one of the more effective methods of removing organic micropollutants (OMP) from wastewater. Activated carbon is a porous material with a large surface area that allows adsorption of other substances. The material does not exist naturally and therefore has to be produced. The production can be done from any carbon-rich material and today the precursor is mai

Rennet coagulation ability of milk is of utmost importance in cheese manufacturing industry since it is directly related to cheese quality and yield, then translated into economic benefit. This study examined the rennet coagulation ability and composition of milk from individual Swedish Red (SR) cows, the second most common dairy breed in Sweden. Additionally, the study explored how the presence o

The purpose of this research is to achieve a deeper insight of the emulsifying, suspending, and gelling properties of the meat proteins and see the possibility to use them to produce reduced-salt emulsion-type sausages. Sarcoplasmic and myofibrillar proteins were extracted from pork (longissimus dorsi, LD). Firstly, their aggregation behaviors in different salt concentrations – namely, 0.15 M, 0.4

Buildings from the so called Million programme has a high use of energy and in addition, there are many such houses. The need for them to be retrofitted is big. The City of Helsingborg has set a climate goal which states that the city in 2035 should be neutral in energy use which put a lot of pressure on the real estate owners in the city. All new buildings has to be energy efficient and older bui

Electrical machines in electrical vehicles are sometimes put under a lot of stress when for example climbing an uphill road. In order for the machine to cope with the heat generation that comes of running extended periods of time near or at peak power one needs a highly developed cooling system. At the division of Industrial Electrical Engineering and Automation (IEA), located at Lunds Tekniska Hö

Miljöproblemen vet inga gränser och påverkar hela mänskligheten kollektivt. Historiskt har dock tillgången till rättslig prövning i svensk rätt kretsat kring individuella intressen. Århuskonventionen, som både Sverige och EU sedan år 2005 är parter till, introducerar en bindande mekanism där miljöorganisationer ges rätt att företräda det kollektiva intresset genom att väcka talan mot myndighetsåtgEnvironmental challenges know no borders and collectively impact all of humanity. Historically, access to judicial review in Swedish law has centered around individual interests. The Aarhus Convention, to which both Sweden and the EU have been parties since 2005, introduces a binding mechanism granting environmental organizations the right to represent collective interests by initiating lawsuits a

This study used the urban context of Brunnshög, Sweden as a real case study to assess non-visual daylight conditions in urban environments. More precisely, the work was focusing on how the light spectrum – through surrounding façade colour and window type – can have an impact on the circadian potential. A one-bedroom apartment opening onto a courtyard on the ground floor and the same apartment on

Background Previous studies of minimally invasive liver surgery described results and experiences in high-volume centres and early adopters, but data on national levels are lacking. This study evaluated the implementation and outcomes of minimally invasive liver surgery in Sweden over a 15-year period, with a focus on colorectal liver metastases. Methods Data from patients undergoing liver surgery

Background. Climate change is the greatest threat to human health in the 21st century and healthcare contributes to approximately 5% of global greenhouse gas emissions. Intensive and perioperative care are particularly resource intensive. This thesis aimed to assess the climate and environmental impacts of perioperative and intensive care (Papers I–III) and to explore how environmental outcomes an

Background The dura mater has a permeable vasculature similar to that of peripheral organs, and is separated from the brain, which is enclosed within the arachnoid barrier. Fluid and solute transport across the arachnoid barrier between the subarachnoid space (SAS) and dura is crucial for brain waste clearance and immune surveillance, but few neuroimaging approaches can capture this dynamic proces

Background and purpose: Stereotactic radiosurgery (SRS) requires high positional accuracy to safely deliver large doses. This study evaluated an integrated surface- and image-guided radiotherapy (SGRT-IGRT) system by analysing (1) the agreement between thermo-optical and stereoscopic X-ray positioning, and (2) the impact of intra-fractional workflows on treatment accuracy and time. Materials and m

This thesis is built upon four research projects, in which we investigated different aspects of increasing the diagnostic yield of blood cultures. Blood culture sampling using a single venipuncture (single-sampling strategy, SSS) is non-inferior to sampling from two separate venipunctures when sensitivity is considered. The effect of SSS on blood culture contamination rate is less known. In Study

Premise: Flower color, a key trait influencing plant–pollinator interactions, may be influenced by abiotic factors such as soil. We investigated association between pollinators, soil characteristics, and flower color variations in Digitalis purpurea across native populations in Sweden and introduced populations in Bolivia. Methods: We measured floral traits, reflectance of petals and nectar-guide

Taurine, an amino sulfonic acid abundant in seafood and meat, has been proposed to have a potential role in the prevention of metabolic dysfunction-associated steatotic liver disease (MASLD) due to its antioxidant and anti-inflammatory properties. However, the association between dietary taurine intake and MASLD remains unclear in human populations. Also, data on dietary taurine intake among adult

Design A nationwide cohort study based on linked healthcare register data encompassing patient characteristics, prescription data and cases of aortic and mitral valve regurgitation. Setting Sweden, 2006–2018. Participants Study participants were a
