Cementbaserade material, såsom murbruk och betong, är världens mest använda byggnadsmaterial. Cement är en viktig delkomponent; det reagerar med vatten och bildar ett lim, kallad cementpasta, som får materialet att hårdna. Idag står cementproduktion för en betydande del av världens årliga koldioxidutsläpp. Genom att byta ut delar av cementet mot andra material med cement-lika egenskaper, till exemCement-based materials, such as mortar and concrete, are the most employed construction materials in the world. Cement is an important component; it reacts with water to form a glue, called cement paste, which causes the material to harden. Today, cement production accounts for a significant portion of the world’s annual carbon dioxide emissions. Replacing parts of cement with other materials that

Image quality measures are becoming increasingly important in the field of computer graphics. For example, there is currently a major focus on generating photorealistic images in real time by combining path tracing with denoising, for which such quality assessment is integral. We present FLIP, which is a difference evaluator with a particular focus on the differences between rendered images and co

Wood is a porous, hygroscopic material with engineering properties that depend significantly on the amount of water (moisture) in the material. Water in wood can be present in both cell walls and the porous void-structure of the material, but it is only water in cell walls that affects the engineering properties. An important characteristic of wood is therefore the capacity for water of its solid

Stroke är en mycket vanlig sjukdom och idag räknar man med att det finns över 140 000 drabbade i Sverige som lever med varierande grad av funktionell nedsättning. Prognosen efter stroke påverkas av många olika faktorer varav flera tidigare inte fått så mycket uppmärksamhet. Den här avhandlingen ämnar ge en heltäckande bild av långtidsprognosen och varje delarbete fokuserar på olika viktiga aspekteBackground: Stroke is a major cause of mortality and disability. Prognosis is constantly evolving and is affected by multiple factors, many of which have not previously been thoroughly analyzed. This thesis aims to provide an updated and comprehensive description of long-term prognosis after stroke, specifically exploring key factors such as comorbidity (Study II), pre-stroke functional dependency

The use of the structural similarity index (SSIM) is widespread. For almost two decades, it has played a major role in image quality assessment in many different research disciplines. Clearly, its merits are indisputable in the research community. However, little deep scrutiny of this index has been performed. Contrary to popular belief, there are some interesting properties of SSIM that merit suc

Digital technology plays an important role in our work places, and much time is spent in the virtual environments that technol-ogy provides. However, today’s digital work environments are often cumbersome and hard to use, and contribute to stress and ill-health with subsequent cost to the individual, to their employ-ers and to society. Our long-term aim is to facilitate the develop-ment of IT syst

A new project based on continuous bi-annual surveys of hectare plots is introduced with the aim to monitor future floristic changes as well as environmental conditions that may be assessed based on species-specific plant traits or ecological indicator values. As a trade-off between the needs for representativeness at the landscape scale and field work efficiency, the hectare plots have been placed

Prostatacancer är den vanligaste cancern bland män i Sverige. Varje år insjuknar ca 10 000. Sjukdomen är starkt åldersberoende och är mycket vanlig bland äldre män. Latent cancer (icke kliniskt signifikant) förekommer ofta. Sjukdomen klassificeras som låg, mellan eller högrisk baserat på Gleason summa (tumörens aggressivitet), stadium och PSA. Val av behandling sker utifrån riskgrupp och ålder. LåAbstract Backgound Prostate cancer is the most common form of cancer in men in Sweden. Radiotherapy, including external beam radiation therapy (EBRT) and brachytherapy (BT), is important treatment alternatives to surgery and active surveillance. Precise delivery of the prescribed absorbed dose to the prostate with minimal irradiation of normal tissue, specifically organs at risk, is crucial for op

Ceria-based heterostructure composite (CHC) has become a new stream to develop advanced low-temperature (300–600 °C) solid oxide fuel cells (LTSOFCs) with excellent power outputs at 1000 mW cm−2 level. The state-of-the-art ceria–carbonate or ceria–semiconductor heterostructure composites have made the CHC systems significantly contribute to both fundamental and applied science researches of LTSOFC

By focusing on recent water struggles in rural Turkey against run‐of‐the‐river hydropower plants (SHPs), the research delves into the societal and economic factors that enable or inhibit the emergence of strong mobilizations through a comparison of four localities of the Eastern Black Sea region. The main aim of the cross comparison is to determine whether there is a relationship between the forms

Det här kapitlet fokuserar på relationen mellan arbetsliv och övrigt liv och ett antal digitala strategier som används för att hantera denna. Tidigare forskning har visat att kvinnor i jämförelse med män möter en större utmaning i hanterandet av denna gränsdragning, givet att kvinnor, traditionellt sett, har haft ansvaret för barn samt utfört mer av det obetalda arbetet i hemmet (Hochschild &

Technical universities is an omnibus concept, which may conceal variations. This is the fundamental assumption of this chapter, which deals with three technical universities in three European countries: KTH in Sweden, DTU in Denmark, and EPFL in Switzerland. Based on an analysis of scientific impact profiles and their alignment with government steering, funding and internal organisation and leader

Vår slutsats är att vi finner att det finns viss evidens för att det kan finnas ett orsakssamband mellan Preemraff’s utsläpp och en ökad risk för leukemi, även om man aldrig helt kan utesluta slumpen, så är den ganska osannolik i detta fall. Eftersom det finns en stor osäkerhet för hur mycket bensen som befolkningen redan utsatts för historiskt och det är den kumulativa dosen som kan vara skadlig
