Avhandlingen handlar om samtida föräldraskap och skärmtid. Skärmtid används ofta i vardagligt språkbruk för att beteckna aktiviteter på och kring skärmteknologier, men det har även blivit ett fenomen som ofta beskrivs i termer av konfrontation, osäkerhet och frustration i hemmet (Livingstone & Blum-Ross 2020; Sandberg et al. 2024a). Föräldrar förväntas hantera och kontrollera deras barns skärmThe dissertation is about modern-day parenting in relation to what is commonly known as screen time. While screen time in everyday language is used to connote activities on screen technologies, it has become a phenomenon which often describes a site of struggle, uncertainty and frustration in the domestic space (Livingstone & Blum-Ross 2020; Sandberg et al. 2024a). Parents are expected to mana

To address global food security challenges caused by population growth and climate change, accurate prediction of crop yield is essential for sustainable agriculture. Winter wheat, a key global crop, faces production instability in regions like Sweden and Morocco due to extreme weather conditions. This study employed unmanned aerial vehicle (UAV)-based multispectral imagery and digital surface mod

The Journal of Clinical Investigation     R e s e a r c h a r t i c l e 1jci.org Introduction Upon inflammation, an array of brain-mediated responses occurs. They are collectively referred to as the sickness syndrome and include fever, decreased food intake, inactivity, social withdrawal, and corticosteroid secretion (1, 2). These objective symptoms are accompanied by feelings of malaise and disco

During the course of this three-year project, we have studied aeolian deposits at 70 sites within sixteen areas in south-central Sweden. Inland dunes have been the focus, but some sites with coversand and coastal dunes have also been investigated. We have mapped dune morphology, mainly by LiDAR-based remote sensing, studied the internal sediment architecture by ground-penetrating radar profiling a

Developing high-temperature proton exchange membranes (HT-PEMs) that simultaneously achieve high proton conductivity, strong phosphoric acid (PA) retention, and long-term chemical stability remains a major challenge, particularly due to PA-induced plasticization and radical-induced oxidative degradation. Here, we develop a side-chain engineering strategy to decouple PA-binding sites from the polym

This thesis presents structural and morphological studies of semiconductor nanostructures, namely quantum dots, nanowires and a dilute ferromagnetic semiconductor. These nanostructures are investigated on the atomic scale using cross-sectional scanning tunneling microscopy (XSTM). Indium arsenide (InAs) quantum dots in both an indium phosphide (InP) and GaAs matrix are studied. The InAs/InP quantu

Popular Abstract in Swedish Som ett skepp uti vilda havet, den kristna församlingen i ärkebiskop Laurentius Petris verk I 1593 års Uppsala mötes "förening om läran, ceremonier och kyrkotukt" finns följande avsnitt : Thernäst bejake och vederkännes vi oss alldeles vele holle vidh the Apostoliske, Niceniske och Athanasii symbola, såsom och vidh then äldste, rätte och oförrandrede Ausburgiske confeThe aim of this thesis is to present the ecclesiology of Laurentius Petri, a former student at Wittenberg who was archbishop of Uppsala from 1531 to his death 1573. He had a decisive role in the founding of the Church of Sweden, especially through his Swedish Church Ordinance(1571). Nevertheless most of his seventy-three writings are little known and have been rarely studied. Chapter one st

Questions Can the model performance of the landscape reconstruction algorithm (LRA) for small forest hollows be validated through comparison to inventory-based vegetation reconstructions from the last 150yrs? Does the application of LRA and the comparison to historical data enhance interpretation of the pollen record? Location Denmark. The Gribskov-Ostrup small forest hollow (56 degrees N, 12 degr

Questions: To what extent does the long-term process of grassland succession reflect changes in nutrient availability or other effects of grassland history? Plant communities in ancient, semi-natural pastures include many species associated with nutrient-poor soils. However, semi-natural pasture communities can also develop on previously arable sites — as nutrient levels decline over time. In Euro

The research area of climate field reconstructions has developed strongly during the past 20 years, motivated by the need to understand the complex dynamics of the earth system in a changing climate. Climate field reconstructions aim to build a consistent gridded climate reconstruction of different variables, often from a range of climate proxies, using either statistical tools or a climate model

Construction in rock is associated with risks because knowledge of the geology and ground conditions is limited. Unforeseen rock conditions involve a large risk to the project and can in the end entail delays and extra costs. To minimize the risks, an optimized pre-investigation program has to be conducted where essential information is gathered in order to make the best decisions throughout the c

Oilseed rape fields are a very common crop in the agricultural landscape of southern Sweden, and they can harbour surprisingly many insect species. Some of them are herbivores that feed on various parts of the oilseed rape plant, others are natural enemies of the herbivores, and even more species are tourists from the surrounding landscape. In my thesis I have studied these insects and how their pOilseed rape fields are a very common crop in the agricultural landscape of southern Sweden, and they can harbour surprisingly many insect species.

Catalytic breakdown of polysaccharides can be achieved more efficiently by means of the enzymes lytic polysaccharide monooxygenases (LPMOs). However, the LPMO mechanism has remained controversial, preventing full exploitation of their potential. One of the controversies has centered around an active site tyrosine, present in most LPMO classes. Recent investigations have for the first time obtained

An evaluation has been made of the capability of rapeseed oil to dissolve polycyclic aromatic hydrocarbon (PAH) crystals in a biphasic system and of its capability to extract PAHs from polluted soil in a two-liquid-phase (TLP) slurry system. Up to 220 g l(-1) of the crystalline hydrocarbons could be dissolved in the organic phase, indicating oil/water-partitioning coefficients of 10(5). When soil

Anthropogenic activities such as hydropower exploitation have been one of the main drivers of anadromous fish biodiversity loss during the past century. This has led to genetic homogenization and to the reduction of positive mechanisms such as the “portfolio effect”. In this study we propose the first comprehensive analysis of the genetic differences in Salmo salar and Salmo trutta populations in

The present thesis investigated using the random forest machine learning algorithm for wind power forecasting. Meteorological prognoses for wind speed, wind direction, gust winds, and humidity were used. For historical data, wind minimum and temperature was also included. The results were evaluated using root means square error (RMSE), mean absolute error (MAE), normalized mean absolute error (NMA

The conservation value of sandy habitats for a flora and fauna adapted to open, light, dry, warm, and often nutrient-poor conditions, is well recognized. Today this environment is threatened by lack of disturbance, fragmentation and exploitation, acidification and increased levels of nitrogen and phosphorus. Traditional management such as mowing and grazing have proven unsuitable for restoring pop
