Species composition affects the carbon turnover and the formation and emission of the greenhouse gas methane (CH4) in wetlands. Here we investigate the individual effects of vascular plant species on the carbon cycling in a wetland ecosystem. We used a novel combination of laboratory methods and controlled environment facilities and studied three different vascular plant species (Eriophorum vagina
The effect of the anionic surfactant SDS (sodium dodecyl sulfate) on the adsorption behavior of cationic hydroxyethyl cellulose (Polymer JR-400) and hydrophobically modified cationic cellulose (Quatrisoft LM-200) at hydrophobized silica has been investigated by null ellipsometry and compared with the previous data for adsorption onto hydrophilic silica surfaces. The adsorbed amount of LM-200 is fo
The excited-state processes of protochlorophyllide a, the precursor of chlorophyll a in chlorophyll biosynthesis, are studied using picosecond time-resolved fluorescence spectroscopy. Following excitation into the Soret band, two distinct fluorescence components, with emission maxima at 640 and 647 nm, ore observed. The 640 nm emitting component appears within the time resolution of the experiment
Various ecosystems, including shallow lakes, are suggested to possess alternative stable state dynamics. The response of such systems to environmental change is non-linear and not fully reversible, which calls for identification of feedback mechanisms and subtle changes connected to structural stability. Here, we used a 25-year data series on water chemistry to make inferences on processes prior t
Popular Abstract in Swedish Denna avhandling undersöker hur vi använder visuell kontextinformation i samtal. Alla modeller över språkprocessning och kommunikation är ense om att visuell kontextinformation har en positiv nettoeffekt på förståelse och kommunikation. Trots detta är det inte klart genom vilka mekanismer denna kontextinformation verkar, eller om dessa mekanismer fungerar i situationer This dissertation is about the role of visual context information in communication. All accounts of language processing and communication agree that visual context is beneficial for understanding. Despite this, it is not clear through which mechanisms visual context works and whether these mechanisms also work in communication outside the lab setting. This dissertation aims to provide answers to t
Families living with a person with mental illness can experience distress requiring therapeutic interventions. Web-based mindfulness interventions have shown beneficial health outcomes for both clinical and healthy populations, and may help families cope and overcome barriers that can otherwise hinder a help-seeking process. Aims: To develop and assess outcomes of a web-based mindfulness intervent
To be a caregiver while also being next of kin is emotionally charged. This article discusses narratives of care that goes beyond what Amelia DeFalco calls “caregiving at the limit”, i.e. care necessary for basic survival. In these narratives of what we call desperate care, not only is life at stake, but the care is anxious and urgent, partly done against the will of the care recipient, and the ca
Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. A look to the future reveals that vanadium may play a role in renewable
The master thesis was done at QPharma to investigate a processing problem during production of tablets, where an excessive volume expansion during dry mixing of three ingredients occurred from time to time. A volume expansion (dilation) is needed for particles, within a powder, to become mixed with other particles. However, the extent of the dilation is dependent on intermolecular forces between p
Creative agency acquisitions by leading management consulting firms is a phenomenon that was recently discovered. Therefore, very few studies have explored M&As within this specific context. This lack of research is surprising because in today’s highly competitive environment businesses increasingly have started acquiring external creative capabilities to be able to provide end-to-end solution
The aim of this study was to look into the discretion that the probation officer executes in cooperating with lay supervisors. In Sweden about fifty percent of the offenders sentenced to probation or on parole have lay supervisors and these supervisors are appointed by the probation officers. I asked the officers what they were looking for in a lay supervisor, certain qualifications or personaliti
Datalagring och integritetsskydd är två föränderliga lagstiftningsområden inom EU-rätten. Myndigheters tillgång till konfidentiella personuppgifter har under det senaste decenniet varit både mer och mindre långtgående än idag. Uppsatsen har till syfte att ge en kronologisk överblick över datalagringens framväxt och tillbakagång inom EU-rätten, från dataskyddsdirektivet och datalagringsdirektivet tGovernment data retention and privacy laws are two areas of legislation where the EU has been very active. The access to private information for governmental agencies has been both more and less advanced during the last decade. This paper aims to give a chronological overview of the larger changes to EU government data retention laws; from the secondary law of the Data Protection Directive and the
Barnets bästa ska vara avgörande vid alla beslut som rör vårdnad, boende och umgänge. Vid bedömningen av barnets bästa skall hänsyn tas till barnets vilja med beaktande av barnets ålder och mognad. Det framgår tydligt av såväl FN:s konvention om barnets rättigheter (barnkonventionen) och av svensk lag. Lagtexten ger endast vägledande riktlinjer när det gäller bedömningen av barnets bästa för att uThe best interest of the child should always be decisive in all decisions concerning custody, accommodation, and relations of the child. When assessing what is best for the child the will of the child should be considered. Moreover, the will of the child should be evaluated according to two affecting factors; age and maturity. This clearly appears in the Convention on the Rights of the Child prese
Iceland is known for its remote location and rough beauty. In their seclusion, the Icelanders have built an independent and peaceful country. They are undeniably a very unique nation, where police officers are not allowed to carry guns, except on special occasions. The society displays a relaxed attitude towards prisons, which are built without concrete walls around. However, faced with the immens
The purpose of this study was to examine the Minnesota model and the meaningful moments experienced by people who have gone through the Minnesota treatment. Our aim was also to analyze this treatment from an interactionist perspective using the turning points theory, the labeling theory, Ervin Goffman’s dramaturgical perspective and, the interactionist perspective view on the emotion shame. We hav
Kiviks Musteri AB has a vision to maintain a good environmental profile with a sustainable production. To achieve this, the aim is to decrease the product wastage and water consumption. Apart from the increased sustainability, this also leads to an increased income and is essential for the growth of the company. The main aim with this master thesis is to identify and chart the product wastage and
A 3D model is developed to describe an anode-supported planar solid oxide fuel cell (SOFC), by ANSYS/Fluent evaluating reactions including methane steam reforming (MSR)/water-gas shift (WGSR) reactions in thick anode layer and H-2-O-2/CO-O-2 electrochemical reactions in anode active layer, coupled with heat, mass species, momentum, and ion/electron charges transport processes in SOFC. The predicte
Background: S100A9 has been shown to be important for the function of so called Myeloid Derived Suppressor Cells (MDSC). Cells with a similar phenotype are also involved in pro-inflammatory processes, and we therefore wanted to investigate the gene expression and function of these cells in animals that were either subjected to chronic inflammation, or inoculated with tumors. Methods: CD11b(+)Ly6C(
The thesis discusses closed-loop control of the hypnotic and the analgesic components of anesthesia. The objective of the work has been to develop a system which independently controls the intravenous infusion rates of the hypnotic drug propofol and analgesic drug remifentanil. The system is designed to track a reference hypnotic depth level, while maintaining adequate analgesia. This is complicat
