The purpose of this thesis is to determine how electric vehicle trucks can meet the needs of customers in the urban building and construction sector. This sector contributes significantly to greenhouse gas (GHG) emissions, and also creates noise and other disturbances in urban environments. There are multiple benefits that come with electric trucks, which can address these issues if they are used
Förenta Nationernas fredsbevarande operationer har under nästan två decennier besvärats av anklagelser om sexuellt utnyttjande av och sexuella övergrepp på civilbefolkningar. Flera rapporter visar inte bara att organisationens fredsbevarande styrkor begår dessa brott mot just de människor de fått i uppdrag att beskydda, utan också att de undgår ansvar och straff. Denna uppsats undersöker och utvärUnited Nations peacekeeping operations have, for the better part of two decades, been plagued by allegations of sexual exploitation and abuse of local civilian populations. Several reports indicate not only that peacekeepers exploit and abuse the very people they were sent to protect, but also that these crimes routinely go unpunished. This thesis examines and evaluates the different methods of ho
Due to the focus of their study program, environmental and sustainability students are vulnerable to experience negative emotional impacts, potentially affecting their mental health. This thesis contributes to increased understanding of emotions and emotional resilience in relation to the climate crisis by examining experienced emotions, studying the power students have over their emotions, and po
As the need to adapt to a changing climate and the political rhetoric in this regard are growing, Berlin’s Senate has issued strategic policies – complemented by an increase of funding. Berlin’s socio-cultural features and place-based factors seem predisposed for so-called “Nature-based Solutions” (NbS) that can support the achievement of adaptation efforts. This encouraging context seems to be co
Climate change is the greatest challenge of our time. Despite efforts to reduce greenhouse gas (GHG), the emissions contribution from global aviation is set to increase. Electric aviation has emerged as an alternative which could form part of the solution. Sweden, which is on the path to carbon neutrality and has a long history in aviation, could contribute to the global efforts in mitigating clim
Smart City is a paradigm for the development of urban spaces through the implementation of state-of-the-art ICT. There are two main approaches when developing Smart Cities: top-down and bottom-up. Based on the bottom-up approach, the concepts of Smart People and Smart Communities have emerged as dimensions of the Smart City, advocating for the engagement of citizens in Smart People initiatives. Th
Randomized, double-blind, controlled studies have shown that treatment with risedronate reduces the risk of vertebral fracture in postmenopausal women with established vertebral osteoporosis. They also show that the drug decreases the risk of non-vertebral fractures in women with osteoporosis. The aim of this study was to investigate the cost-effectiveness of risedronate in postmenopausal women wi
Cells continuously export, import, and recycle molecules over the plasma membrane. Internalization, i.e. cellular import of extracellular material, is a fundamental process, which provides cells with nutrients and enables the immune cells of higher organisms to remove debris, sample their surroundings for antigens and to fight microbes. Moreover, internalization regulates complex cellular signalli
New radiative lifetimes for 20 levels of Pr II have been measured using the time-resolved laser-induced fluorescence (LIF) technique. The combination of these experimental values with theoretical branching fractions (BF) obtained with the pseudo-relativistic Hartree-Fock (HFR) approach has allowed us to determine oscillator strengths and transition probabilities for about 150 lines appearing in th
The aim of this study was to determine the threshold of fracture probability at which interventions became cost-effective in men and women, based on data from Sweden. We modeled the effects of a treatment costing $500 per year given for 5 years that decreased the risk of all osteoporotic fractures by 35% followed by a waning of effect for a further 5 years. Sensitivity analyses included a range of
A resistivity and time-domain induced polarization (IP) survey was conducted at a landfill Site under restoration at Harlov in Southern Sweden. The covering of the landfill had begun some years ago, without keeping precise records of the work done, as is usual in such procedures. The survey was conducted in two steps, on two adjacent areas. First, a number of geoelectrical sections were made on a
Hexahydrophthalic anhydride (HHPA) and methylhexahydrophthalic anhydride (MHHPA) are highly allergenic compounds used in the chemical industry. The aim of this study was to characterize the protein adducts in erythrocytes following exposure to HHPA and MHHPA. Blood and urine samples were obtained from 51 HHPA- and MHHPA-exposed workers. Erythrocytic proteins from HHPA- and MHHPA-exposed workers we
OBJECTIVE: To evaluate the effects of the three commercially available colloid solutions, 6% dextran 70, 6% hydroxyethyl starch (HES) 200/0.5, and 3.5% urea-linked gelatin on permeability for human albumin in a skeletal muscle in vivo model by evaluating their effects on the reflection coefficient for albumin. DESIGN: Controlled laboratory study. SETTING: University research laboratory. SUBJECTS:
Cellulases hydrolysing the interior parts of cellulose, also called endoglucanases, were immobilised in micro-immobilised enzyme reactors (RIMER) made of porous silicon with the purpose of investigating the use of such mu IMERs for hydrolysis of cellodextrins and soluble cellulose derivatives. The endoglucanases Trichoderma reesei Cel 12A (TrCel 12A) and Bacillus agaradhaerens Cel 5A (BaCel 5A) we
Background: In most clubfoot studies, the outcome instruments used are designed to evaluate classification or long-term cross-sectional results. Variables deal mainly with factors on body function/structure level. Wide scorings intervals and total sum scores increase the risk that important changes and information are not detected. Studies of the reliability, validity and responsiveness of these i
High-spin terminating bands in heavy nuclei were first identified in nuclei around Er-158(90). While examples of special terminating states have been identified in a number of erbium isotopes, almost nothing is known about the states lying beyond band termination. In the present work the high-spin structure of Er-157 has been studied using the Gammasphere spectrometer. The subject of triaxial supe
