This thesis is a concept study performed at Caran AB by order of Volvo Car Corporation, VCC. The background is a market research performed by VCC. From the research, a need for a product that facilitates reaching the trunk level in Volvo’s SUV, XC90, was recognized. It was also found, that dogs seem to find it difficult to get up in the trunk, why dogs have been accounted for during the developmen
Frequent land-use changes in urban areas require an efficient and dynamic approach to reform and update detailed plans by re-arrangement of surrounding land-uses in case of change in one or several urban land-uses. However, re-arrangement of land-uses is problematic, since a variety of conflicting criteria must be considered and satisfied. This paper proposes and examines a two-step approach to re
Evacuation planning is an important activity in disaster management to reduce the effects of disasters on urban communities. It is regarded as a multi-objective optimization problem that involves conflicting spatial objectives and constraints in a decision-making process. Such problems are difficult to solve by traditional methods. However, metaheuristics methods have been shown to be proper solut
European rivers experience increased loading of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, little is known about how increased TOC is linked to changes in the bioreactivity of organic matter in these rivers on a continental scale. We compiled paired measurements of TOC and biological oxygen demand in 5‐day 20
Framväxten av digitala plattformar håller för närvarande på att förändra hur kulturarbete förmedlas och utförs. Trots detta finns det en brist på forskning, inte minst i en svensk kontext, som studerar kulturarbete som ett typexempel på det som kommit att kallas gigarbete. Den här avhandlingen analyserar frilansande kulturarbetares erfarenheter av att navigera den digitala plattformsekonomin för aCultural industries are currently being transformed by processes of platformization and precarization. Despite being among the sectors where platformization has already had the most pronounced effects, there remains a lack of research on cultural work as a prototypical example of so-called gig work. This dissertation analyzes the working experiences of what I call digital freelancers — solo self-e
A Slow Sand Filter (SSF) consists of biofilm attached to saturated packed sand with supernatant water on top, through which water flows by gravity. SSFs are used in the production of drinking water to improve water quality and remove pathogens, and, as they use biological filtration via the microbes present in the biofilm, they are simple and cheap to construct. A drawback of SSFs is that the diff
Background and Hypothesis: Social cognition training (SCT), an intervention for social cognition and social functioning, might be improved by using virtual reality (VR), because VR may offer better opportunities to practice in a potentially more realistic environment. To date, no controlled studies have investigated VR-SCT. This study investigated a VR-SCT, "DiSCoVR". We hypothesized that DiSCoVR
An improvement in photosynthetic rate promotes the growth of crop plants. The sink-regulation of photosynthesis is crucial in optimizing nitrogen fixation and integrating it with carbon balance. Studies on these processes are essential in understanding growth inhibition in plants with ammonium ((Formula presented.)) syndrome. Hence, we sought to investigate the effects of using nitrogen sources wi
The cortico-basal ganglia system is instrumental in the construction of movement, through its involvement in aspects such as action selection, initiation/termination and sequencing, though the precise role of the different structures and how they collaborate on a network level to allow us to fluidly change from one behavior to another has long proven to be elusive.We have here recorded neuronal acti
This paper considers instantaneous impulses in multibody dynamics. Instantaneous impulses may act on the multibody from its exterior or they may appear in its interior as a consequence of two of its parts interacting by an impact imposed by a unilateral constraint. The theory is based on the Euler laws of instantaneous impulses, which may be seen as a complement to the Euler laws for regular motio
We present a radial velocity (RV) analysis of TOI-1136, a bright Transiting Exoplanet Survey Satellite (TESS) system with six confirmed transiting planets, and a seventh single-transiting planet candidate. All planets in the system are amenable to transmission spectroscopy, making TOI-1136 one of the best targets for intra-system comparison of exoplanet atmospheres. TOI-1136 is young (∼700 Myr), a
Soil microbes play an important role in governing global processes such as carbon cycling, but it is challenging to study them embedded in their natural environment and at the single cell level due to the opaque nature of the soil. Nonetheless, progress has been achieved in recent years towards visualizing microbial activities and organo-mineral interaction at the pore scale, especially thanks to
Protein aggregation is a key process in the development of many neurodegenerative disorders, including dementias such as Alzheimer's disease. Significant progress has been made in understanding the molecular mechanisms of aggregate formation in pure buffer systems, much of which was enabled by the development of integrated rate laws that allowed for mechanistic analysis of aggregation kinetics. Ho

Rapid urbanization in Guangdong Province has severely impacted river systems due to limited understanding of the sustainability of river connectivity and functions. This study applies the Minimum Cumulative Resistance Model (MCRM) to quantify expansion costs of natural and social processes, with their difference defined as the River Ecological Sensitivity (RES) index. Higher RES values indicate th
Populärvetenskaplig sammanfattning: Rassepautasjtjåkka är ett litet bergsmassiv beläget i norra Lappland. I massivet återfinns fyra stora nischer strax under glaciationsgränsen. Dessa nischer har en gång blivit uteroderade av glaciärer, men idag återfinns endast perenna snölegor i området. Skillnaden mellan en glaciär och en perenn snölega är att en glaciär har intern rörelse. En tjocklek på cirkaSince the mid 1970s the general retreating trend for glacier in Scandinavian have ceased and some glaciers have even started to advance. This is due to a more maritime influence on the climate, which means increased precipitation in winter and lower summer temperature. A more maritime climate can be said to be favourable for glacier growth. Under such climate conditions is it possible that new gla
In this work we have critically reviewed the processes in high-temperature sublimation growth of graphene in Ar atmosphere using closed graphite crucible. Special focus is put on buffer layer formation and free charge carrier properties of monolayer graphene and quasi-freestanding monolayer graphene on 4H–SiC. We show that by introducing Ar at higher temperatures, TAr, one can shift the formation
The operation of next-generation particle accelerator facilities with increased beam power parameters and emphasis on performance and reliability signifies the need for experimental studies on material property degradation. Literature is particularly scarce regarding the effects of ionizing radiation damage on cavity components at applicable radiation conditions, with even less extant work studyin
Heavy metal pollution from untreated industrial wastewater has become a major concern to the environment and public health in many rapidly growing cities in low-income countries. Previous studies on heavy metals of urban wastewater systems have focused on long-term (weekly or seasonal) variations, while only few studies investigated short-term (daily) variation to capture potential bulk discharges
