In Sweden, energy utilities face the double challenge of complying with the Kyoto protocol targets and increasing renewable energy capacity to make use of the electricity certificates system. Sydkraft AB and Vattenfall AB, two of the largest players in the Nordic electricity market, have different expectations regarding the future development of the two mechanisms and, therefore, have different ap
With population aging, more adults across Europe face competing demands of working for pay and caring for elderly family members. Associated tradeoffs are expected to be negative, gendered, and vary across contexts with different levels of gender equality, public support for eldercare, and work-family balance. Using SHARE data from 2004–20, this study investigates how unpaid caregiving to independ
Biases in animal behaviour research are inevitable consequences of our societal and cultural standpoint. To remove our biases, the first stage is to identify them. We call on individual researchers to adopt a more active approach to addressing bias within their research. We propose that biases exist within a matrix defined by the general acceptance of a bias's existence and the understanding of th
Despite significant efforts to reconstruct the Holocene glacial history in Scandinavia, evidence of glacier fluctuations in Sweden has mostly been limited to palaeoclimatic proxies, while dating of direct geological evidence from glacier forelands is still rare. This is the first study in Sweden that has attempted to fully reconstruct dynamics, chronology and palaeoclimate of a glacier throughout
With the rapid development of blood biomarkers (BBMs) related to amyloid-β (Aβ) pathology in Alzheimer's disease (AD), the question arises whether these can replace the accepted reference standard, positron emission tomography (PET), for assessing Aβ burden. BBMs can differentiate Aβ status reliably in cognitively impaired patients, but two-threshold strategies to further improve their performance
Ouagadougou is a city with three million inhabitants and an increasing demand for water of sufficient quality. New boreholes are drilled to match demand, but their protection from anthropogenic contamination is insufficient. To assess the quality of urban groundwater in Ouagadougou for the first time, a total of 32 borehole water samples were collected and assessed for bacteriological and physicoc
Lentic water bodies (lakes and reservoirs) offer favorable conditions for silica (SiO2) burial in sediments. Recent global estimates suggest that (1) lentic SiO2 trapping is a globally important SiO2 flux, and (2) through reservoir construction, humans have dramatically altered river dissolved SiO2 (DSi) transport and coastal DSi delivery. However, regional to global scale patterns and controls of
Nutritional stability – a food system’s capacity to provide sufficient nutrients despite disturbance – is an important, yet challenging to measure outcome of diversified agriculture. Using 55 years of data across 184 countries, we assemble 22,000 bipartite crop-nutrient networks to quantify nutritional stability by simulating crop and nutrient loss in a country, and assess its relationship to crop
Despite medical, technical, and pedagogical advances, the risk for language impairment is still much higher in deaf and hard-of-hearing (DHH) children than in hearing peers. Research on linguistic, cognitive, and communicative development in DHH children has found a range of basic spoken language deficits. Twenty percent to 50% of deaf children still meet criteria for language impairment. Tests of
Aim A key component of library management is meeting the needs of our users. This requires continuous analysis of user experience followed by library development. The aim of this study was to better understand the use and effect of general user surveys (GUS) and other methods of gathering user input for quality assessment and improvement of library activities. Methods Data collection was done via
Many companies have introduced initiatives to achieve environmental sustainability and improve the wellbeing of the producers. This is the goal of the Era of We – an online platform that strives to disrupt the current market practices, promote environmentally sound coffee production and empower farmers. This thesis explores the perceived power dynamics between different stakeholders and how are th
AbstractThe uptake of different nitrogen forms by understory species was studied in field and laboratory. Species of the understory in deciduous forests have previously been thought to take up and assimilate only inorganic nitrogen sources. However, species also have the opportunity to assimilate amino acids, usually in low rates compared with ammonium, according to solution culture studies, but m
Popular Abstract in Swedish Kolhydrater är viktiga inte bara som bränsle och strukturgivande egenskaper, vilket var uppfattningen för 25 år sedan. De ingår även som en mycket viktig del i hur celler kommunicerar med varandra. Det har de senaste åren visat sig vara kolhydrater inblandade i en mängd signalering- och igenkänningsmekanismer. Några exempel: när bakterier angriper en cell är det oftast Artificial, amfiphilic, and biomimetic receptors soluble in water were synthesized via attaching polar amino acids to hydrophobic back-bones possessing a surface suitable for hydrophobic interactions. The hydrophobic back-bones chosen in this thesis were anthracene and dibenzobarrelene structures. A route to an efficient synthesis of a dibenzobarrelene backbone with two sets of orthogonal reactivi
