The Panama Canal expansion is an external factor on the tanker freight market that is made to change cargo volumes, channel fee income, the average transit time and might also change or create new profitable transportation routes. Shipowners operating in the region will, in one way or another, be affected by this. For tanker shipping companies like Stena Bulk the challenge is to create robustness
In today’s dynamic market the use of knowledge about Human Factors is becoming a competitive mean to drive development and enhance usability. This Master Thesis is an attempt to study how increased machine reliance will affect the usability of equipment at Tetra Pak and also how Human Factors methods can affect and improve the development of new products and processes. The object of study is a n
Iggesund Paperboard Limited works in an increasingly competitive and cost-focused industry. The production is very customised and besides the different product variants some customers also have special requests, which mean activities that fall out of the normal process. The contribution system does not identify the additional costs that depend on the special customer requests. The purpose with th
Interactions between metals and natural organic matter (NOM) are of great environmental importance and one of the key factors influencing hydrolysis, solubility, and speciation of the metals. However, studying geochemically relevant metals like Al, Fe, and Cu is sometimes associated with analytical problems; for example Fe and Cu are both redox active. Gallium (Ga) is a non-redox active metal that
Background: Climate change and increasing threats that come with it fosters a need for changing from fossil sources of energy to renewable ones. Sweden aims to have net zero greenhouse gas emissions by the year of 2045. One of the sectors that need to take part in this shift towards fossil free energy is the transport industry. Electrification of vehicles is an important part of this shift. As a r
Shopping malls are becoming more prevalent throughout the world. They have been identified as having high energy use, which is less explored than other building types. There are 357 shopping centers in Sweden, which has doubled in the last five years. Regardless of national differences in shopping mall tenants' demands, shopping malls always tend to have high lighting loads, high population de
This master thesis is carried out in collaboration with the company Scania which is a provider of transport solutions. The thesis is carried out at Scania’s production unit Engine Assembly where engines are assembled, tested and painted. All engines proceed through a standard test procedure while some of the engines also proceed through special test procedures carried out in the ”Audit Area”. The
Utvecklingen av samhällsfastigheter har under de senaste åren gått från att vara en kommunal angelägenhet till något som allt fler aktörer fått upp ögonen för. Ett stort behov av skolplatser och särskilda boenden för äldre har inneburit att flera svenska kommuner avyttrat sin mark till både privata och kommunala bolag som får stå för utvecklingen av morgondagens skolor och äldreboenden. Försäljnin
The increasingly rapid urbanization has led to vast impervious surface areas in the urban environment. This situation of impervious surfaces has increased the surface temperature and interrupted the natural water circle, which has negatively impacted the urban environment. Human activities' continuous greenhouse gas emission has contributed to global climate change, which has caused some atmos
Suddträsket är ett internationellt erkänt våtmarksområde av stor betydelse som ligger beläget längst Vita Nilen i Sydsudan. Våtmarkens unika ekologiska miljöer har lett till skapandet av flera naturskyddsområden för bevarandet av de naturliga habitaten och dess ovärderliga ekosystemtjänster. Tillsyn av skyddsområdena bidrar i allmänhet till deras bevarande. Däremot har de pågående politiska osäkerThe Sudd wetland, situated along the White Nile in the Republic of South Sudan, is recognized internationally for its unique environmental features. The distinctive ecological characteristics have resulted in the creation of numerous nature reserves in efforts to conserve the habitats and ecosystem services provided. Monitoring changes within the nature reserves usually contributes to their protec
Lipids in the presence of a solvent can through the process of self-assembly form a number of phases referred to as Lipid Liquid Crystalline (LLC) phases. The inverse hexagonal, inverse bicontinuous cubic phases and sponge phase are examples of LLC structures that have been studied and used in drug delivery settings or food applications. For this project the focal point will be the sponge (L3) pha
Implant loosening is a recurring problem in the field of orthopedics, typically resulting in a physical and financial burden for the patient. Proper integration of orthopedic implants within host bones is a fundamental requirement for the successful function and limited risk of failure of implants which, in-vivo, must support various loading conditions. This implant fixation is highly dependent on
The aim of the project was to develop a methodology for the chromatographic analysis able to identify the key odorants in meaty food products. The approach was based on the analysis of an already in market product and the theoretical background of the meaty flavors sensorially. Firstly, a custom-made flavor was created for the experiments covering as much as possible a broad area of compounds prec
Tunnel structures play an important role in Sweden’s infrastructure. At shallow depths, a common construction method is the so-called “Cut-and-Cover” tunnel, where the tunnel placement is excavated, cast in concrete on-site, and then backfilled. Such tunnels are typically subjected to constant water pressure, which yields high demands on crack control. Cracking in elongated concrete structures oft
Uppsatsen analyserar lagförslaget om särskilda provokativa åtgärder och för-slaget om ändring i LUL som aktualiserar åtgärderna för barn under 15 år i SOU 2025:109. Förslagen analyseras mot barns rättigheter enligt barnkon-ventionen. De centrala artiklarna i barnkonventionen är 3.1, 16, 19, 33, 36 och 40. Syftet är att undersöka lagförslagens förenlighet med barnkonventionen ur ett barnrättsperspThis thesis analyses the legislative proposal on a new act regarding special provocative measures and the proposed legislative change in the act concern-ing specific provisions on young offenders (LUL), which makes such pro-vocative measures applicable to children under 15 years of age, in the official report SOU 2025:109. The proposals are analysed against children’s rights under the Convention o
Background: There is increasing recognition of stroke as an important contributor to childhood morbidity and mortality. Current estimates of global childhood stroke burden and its temporal trends are sparse. Accurate and up-to-date estimates of childhood stroke burden are important for planning research and the resulting evidence-based strategies for stroke prevention and management. Objectives: T
AbstractThe overall aims of this thesis were to use echocardiography to non-invasively, delineate early structural andfunctional changes following orthotopic heart transplantation (OHT), and to define reference values in the contextof gender and bridging with mechanical circulatory support.Several factors might affect myocardial function in OHT patients rendering the use of normal values fortranst
BACKGROUND: Breast cancer in young adults has been implicated with a worse outcome. Analyses of genomic traits associated with age have been heterogenous, likely because of an incomplete accounting for underlying molecular subtypes. We aimed to resolve whether triple-negative breast cancer (TNBC) in younger versus older patients represent similar or different molecular diseases in the context of g
Introduction Episodic memory allows us to revisit our past and recollect inter-related elements that characterize life events (Tulving, 1983). When forming such relational memories, we only apprehend a small part of our visual field in full acuity at a time. This limitation is overcome by shifting visual attention over a sequence of eye movements. We bind these visual “samples” of the world into
Increasing CO₂ emission is considered as the main reason for global warming in the world. One of the reasons for producing CO₂ is using of fossil-based materials in the construction projects. This study intends to assess the using bio-based materials instead of fossil-based materials for the thermal insulation layer of the external walls and roofs. Another focus of this project is using green conc
