Nature has been recognized as a rich source of potentially useful chemicals. Throughout the years, phytochemical studies have led to the discovery of an enormous number of natural products, their chemical diversity is unique and many of them possess various biological activities. As a contribution, this thesis presents the results obtained from the phytochemical study of four Bolivian plants. Sene
Popular Abstract in Swedish Fordons körmönster, dvs deras hastighets- och accelerationsprofiler, påverkar avgasutsläpp och bränsleförbrukning avsevärt. Detta projekt syftade till att undersöka körmönster i tätort genom att behandla följande delområden: 1) Hur kan körmönster mätas?, 2) Hur kan körmönster beskrivas? – dvs att finna mått för att karakterisera olika egenskaper hos körmönster., 3) Vad Driving patterns, i.e. the speed and acceleration profiles of vehicles affect exhaust emission and fuel consumption considerably. This project was aimed at investigating urban driving patterns by focusing on the following issues: 1) how to measure driving patterns, 2) measures for the description of driving patterns, 3) identification of characteristics of driving patterns that have significant ef
Popular Abstract in Swedish Bose-Einsteinkondensat är de kallaste system människan känner till, och de styrs helt av kvantmekaniska lagar. Därför har de många speciella egenskaper, som bland annat visar sig under rotation. De kan till exempel inte rotera med vilken hastighet som helst, utan bara vissa specifika hastigheter är tillåtna. Vidare kan man - under vissa omständigheter - få ett Bose-EinsIn this thesis, I explore the behavior of rotating ultra-cold Bose gases, by diagonalizing the Hamiltonian. This method has the advantage of being exact in the limit of weak interactions, and thus is a useful complement to the more commonly used Gross-Pitaevskii (GP) equation, which relies on a mean-field approximation. It is generally known that an ultra-cold Bose gas shows some remarkable proper
Energy-intensive processing industries (EPIs) such as iron and steel, aluminum, chemicals, cement, glass, and paper and pulp are responsible for a large share of global greenhouse gas emissions. To meet 2050 emission targets, a transition to low carbon, often radical innovations is required, but this process is going slow. Insights from sociotechnical and innovation systems perspectives are theref
Increased understanding of the context and context adaptation is needed since effective change implementation and context are connected. This thesis begins to explore the role of context and context adaptation in traffic management change processes to increase knowledge on how organizational change can be managed more successfully.The empirical context for this thesis is The Swedish Transport Admi
1. Grassland is an important habitat for butterflies and many other pollinating insects. Over half of the 501 European butterflies use grasslands as one of their main habitats.2. The Grassland Butterfly Index has been adopted by the EU as a key measure of progress towards the target of halting biodiversity loss, restoring nature in agro-ecosystems and reversing the decline in pollinators by 2030,
Purpose To explore associations between perceived loneliness, social isolation, and health complaints among older people. Methods 5804 participants from the Swedish population study “Good Aging in Skåne” were included. Structured interviews and questionnaires were used to assess perceived loneliness, social isolation, 30 somatic and mental-health related symptoms, socio-demographics, lifestyle, an

Real-life aircraft evacuation drills can cost up to 2 million USD and may not at the same time be able to represent a real emergency scenario. with the use of evacuation models as a complement to the testing may reduce this cost. The aim of this thesis is to test the capabilities and limitation of two continuous evacuation models, namely Pathfinder and FDS + Evac in representing aircraft evacuatio
In this article portrayed experiences of former inmates that were placed in the concentration camps in the beginning of the war in Bosnia and Herzegovina in the 1900s are being analyzed. The article is based on 13 interviews with former inmates and close relatives that currently live in Sweden, Denmark and Norway. The purpose with the article is to describe the social interaction rituals that are
Popular Abstract in Swedish Akrylatallergi Plastmaterial består av stora molekyler som kallas polymerer samt tillsatsämnen som tillsätts för att modifiera materialets egenskaper. Polymerer bildas när det sker en stegvis reaktion mellan monomerer så att större molekyler bildas. Allergiframkallande ämnen i plastsystem kan vara monomererna, härdarna, modifierarna eller andra tillsatsämnen. AkrylaterAcrylate contact allergy has been frequently reported since the 1970s, with hundreds of articles published in dermatology journals so far. The purpose of this thesis was to investigate the frequency of contact allergy to acrylates / methacrylates in patients with exposure to industrial, dental and nail uses of these substances. We also aimed to investigate the clinical and chemical aspects of pa
