Popular Abstract in Swedish I en tid då vi är medvetna om problemen med beroendet av fossila material, både som energi- och råvarukälla, måste vi söka långsiktiga och miljömässigt hållbara lösningar. Katalys kan utgöra ett viktigt bidrag i detta arbete, då det möjliggör reaktioner som annars skulle vara svåra att genomföra på grund av en för hög energibarriär. I takt med den övriga teknologiska ut
Rural development on the island of Gotland has been in decline for years. In the year 2011/12, two uprisings were triggered. The first, the “Countryside Uprisings” was started against the local authority’s move to shut down 11 schools in the countryside and the second, the “Gotlandic Uprising” was against the high cost of ferry travel between Got-land and the Swedish mainland. The undercurrent of
During the biological phosphorus removal (EBPR) process, the phosphorus accumulating organisms (PAOs) accumulates excess phosphorus in the form of polyphosphorus (poly-P) in the aerobic phase. In the following anaerobic zone, PAOs take up volatile fatty acids (VFAs) and simultaneously releases poly-P. Through hydrolysis of the biosludge, the slowly biodegradable organic carbon is degraded into VFA
Alzheimers sjukdom och nanopartiklar – blir vi dementa snabbare? Demenssjukdomar kommer märkbart att påverka vår allt mer åldrande befolkning. Alzheimers sjukdom är den vanligaste av dessa och leder till exempel till minnesförlust och förändrad personlighet. En sak som kännetecknar sjukdomen är bildandet av plack i hjärnan. Plack består av ihopklumpade protein. Proteinet som utgör dessa utgör desAbstract Alzheimer’s disease is a common form of dementia with one of its hallmarks being the formation of plaques in the brain consisting of fibrils formed from the amyloid beta peptide (Aβ). Nanoparticles have in vitro been shown to affect the rate of which these fibrils form. When nanoparticles enter a biological system they will be covered with proteins, a protein corona is formed. In this st
It is estimated that approximately 8-10% of yogurt-based products stick to the carton packaging material surface (Hansson, 2011), and therefore consumers cannot pour the entire product out of the package. This is a multi-dimensional problem since product loss is expensive, because all the resources throughout the supply chain are wasted (European Parliament, 2011; FAO, 2012). In addition, the rema
The energy demand in China is steadily growing and large hydropower dams become more and more common. A major dam failure could cause large environmental, economic and social effects, and work concerning safety in dams is therefore essential in order to keep the utilization of hydropower at as low risk level as possible. This master thesis analyzed Longtan Dam under static and dynamic conditions w
The aim of this study was to describe how families with children, having cognitive disabilities, interacted with portable electronic assistive devices in their daily life. More specifically, its aim was to study the needs for families when they decided to use electronic assistive devices as assistance in their everyday lives, what everyday function they added value to and if they had the same mean
Uppsatsen redogör för rättsreglerna kring omplacering och turordning vid arbetsbristuppsägningar. Det finns ett omfattande regelverk kring anställningsskyddet i Sverige. Det reglerar hur arbetsgivare ska uppträda då uppsägningar ska äga rum. Det krävs saklig grund för att en arbetsgivare ska ha rätt att säga upp en arbetstagare. Detta framgår tydligt ur 7§ anställningsskyddslagen. För att sakligThis essay describes the legal rules regarding relocation and order of priority in connection with termination of employment due to redundancy. There are comprehensive regulations on employment protection in Sweden. It regulates how employers should act when the redundancies will take place. It requires grounds for dismissal for an employer to have the right to terminate an employee. This is evid
The aim of this essay is to find out how the people behind the alcohol abuser (relatives of alcoholics) are able to manage their living situation. We chose to interview six relatives to get answers to our questions. We also chose to interview a drug and alcohol therapist, to get a professional perspective. The questions we asked is were: “Can strategies based on the Coping Theory explain how the r
Cardiac index, systemic and pulmonary arterial pressures, carbon dioxide elimination and ventilation of each lung were studied during thoracotomy. Seventeen patients, placed in the full lateral position, were ventilated mechanically through a Carlens' tube to moderate hypocapnia. Mean cardiac index increased by 12% as the pleura was opened (P less than 0.05), with no further change during surgery
Metal chelate affinity precipitation (MCAP) has been successfully developed as a simple purification process for proteins that have affinity for metal ions. The present lack of widespread applications for this technique as compared to immobilized metal affinity chromatography (IMAC) may be related to the scarcity of well-characterized metal affinity macroligands (AML) and their applications to the
Objectives We determined levels of cognitive functioning in community dwelling men aged 40-79 (n = 3265) from eight European centres and investigated to what extent cognitive performance varied between centres, the association between different cognitive domains and age, educational level, co-morbidity and lifestyle factors and the respective contributions of centre and individual factors to cogni
Cellulose dissolution and regeneration is an increasingly active research field due to the direct relevance for numerous production processes and applications. The problem is not trivial since cellulose solvents are of remarkably different nature and thus the understanding of the subtle balance between the different interactions involved becomes difficult but crucial. There is a current discussion
Climate change is having a discernible effect on many biological and ecological processes. Among observed changes, modifications in bird phenology have been widely documented. However, most studies have interpreted phenological shifts as gradual biological adjustments in response to the alteration of the thermal regime. Here we analysed a long-term dataset (1980-2010) of short-distance migratory r
Open innovation is an emerging innovation paradigm that can greatly accelerate technical knowledge innovation in software companies. The increasing importance and density of software in today’s products and services puts extensive pressure on excelling the discovery, description and execution of innovation. Despite that, software engineering literature lacks methods, tools and frameworks for full
The purpose of this study was to understand how identity could be created in organizations working with microloans. The purpose was also to see how this identity was manifested in term of rules, guidelines and symbolic manifestations. The result of this thesis was analyzed from a symbolic perspective which worked as a tool to understand how identity could be created in an organization working with
