Betong är ett av byggsektorns mest använda material, men cementproduktionen står för stora koldioxidutsläpp. Ett sätt att minska klimatpåverkan är att reducera andelen cementklinker genom att använda alternativa bindemedel. Vulkanisk puzzolan från Island, VPI är ett tillsatsmaterial från Heidelberg Materials Cement Sweden som kan användas tillsammans med cement som bindemedel i betong. TillsatsmatConcrete is one of the most widely used materials in the construction sector, but cement production is associated with a significant climate impact. One way to reduce this impact is to decrease the proportion of cement clinker by using alternative binders. Volcanic pozzolan from Iceland, VPI, is a supplementary material supplied by Heidelberg Materials Cement Sweden that can be used together with

This study aims to deepen the understanding of how automated tipping systems affect guests' restaurant experiences and service interactions in the context of limited bar service in Sweden. Specifically, the study examines how social norms and moral perceptions shape tipping behaviour, what level of service is considered sufficient to warrant a tip and how the design of automated tipping reques

Automated pollen classification is challenging because visually similar species may differ only by subtle morphological characteristics. This thesis investigates deep-learning models for classifying microscopic pollen-grain images from ten plant species using RGB image crops together with two segmentation-derived size measurements: the major and minor axes of the pollen grain. The study builds on

Bolivia, a country located in the center of South America, has in the west part an Andean region, where the Poopó Lake is located. The area has many mineral resources, and thus since thousands of years,mining activity has had a large importance; however, mainly since colonial times, the extraction of these resources has been indiscriminate and the region of the Poopó Lake, has suffered the consequ

The present study addresses the question why there is a positive relationship between nitrogen deposition and potential net nitrogen mineralisation and nitrification in oak (Quercus robur L.) forest soils in south Sweden (Falkengren-Grerup et al., 1998), and how this is related to the carbon mineralisation. We tested three hypotheses based on European studies (Persson et al., 2000a,b) that postula

Popular Abstract in Swedish Den vanligaste dödsorsaken i västvärlden är hjärt-kärlsjukdom. Därför finns det ett stort intresse att undersöka vilka faktorer som är av avgörande betydelse för att vi ska utveckla t.ex ateroskleros (åderförkalkning). Spelar livsstil och matvanor någon roll eller är det helt och hållet genetiskt betingat? Utvecklingen av förebyggande åtgärder, operationsteknik och postMigration and proliferation of smooth muscle cells (SMC) are important events in the development of atherosclerosis and restenosis following angioplastic surgery. It is important to gain further knowledge about the mechanisms regulating SMC form and function in order to understand the underlying disease process. In this thesis I have used cultured rat aortic SMC and analysed how these cells respon

Rationale, Aims and Objectives: Colonoscopy, though common, can be uncomfortable, necessitating routine assessment of patient experience per European guidelines. Positive patient experiences are crucial as they influence willingness for repeat procedures. Patient-reported experience measures (PREMs) effectively capture patient perspectives through surveys, empowering patients to influence healthca

Objectives: Breast-fed (BF) have lower risk of infections during infancy compared to those formula-fed (FF). A higher content of alpha-lactalbumin (α-lac) in breast milk, which may promote a more favorable gut microbiota, could be one reason. In this study, we evaluated whether increased concentration of α-lac in low-protein infant formula affects the immune response and the incidence of infection

Systemic Lupus Erythematosus (SLE) is an autoimmune disease where the immune system is attacking the body and its tissues. This leads to a chronic inflammation that can affect different parts of the body and therefore present itself in a vast variety of symptoms. Depending on the activity of the disease it can go up in flares where the patients experience symptoms and then go down into recession.

Gender diversity has gained a lot of attention in the corporate governance literature, reaching conflicting results whether board gender diversity has an impact on financial performance. As a consequence, we set out to investigate how board gender diversity affects financial performance through innovation using a mediation technique. We constructed three hypotheses grounded in the resource depende

The aim of this study was to examine attitudes surrounding the needle exchange program in Malmö and Lund in Sweden. More specifically the aim was to examine how the staff of the needle exchange program experience the attitudes surrounding the needle exchange program and if/how these attitudes affect them in their work. The analysis of nine interviews with staff members revealed similarities in how

Nanoscience is an emerging field of technology where the bottom-up fabrication techniques are utilized instead of the traditional top-down approaches for enhancing the performance of di erent optoelectronic devices. One such material is a semicon- ductor nanowire (NW) which holds immense potential in nanophotonic applications, such as solar cells, LEDs, lasers, sensors and photodetectors. In parti

Utsläpp av kväve i naturen är ett stort problem eftersom det till exempel kan bidra till övergödning och så kallade döda bottnar i sjöar i akvatiska och marina miljöer. Förmågan att kunna avlägsna kväve från avloppsvatten har därför blivit ett viktigt medel för att bevara och skydda miljön. Kväveavskiljning från kommunala avloppsvatten sker vanligtvis med hjälp av nitrifikation och denitrifikationEmissions of reactive nitrogen to the environment is of major concern, e.g. since it is known to contribute to eutrophication and dead sea floors in water bodies. The capability to remove nitrogen from wastewater has therefore become a critical means of preserving and protecting the environment. Conventional nitrogen removal from municipal wastewaters usually includes nitrification together with d
