We describe the detectors for identification of charged particles and fragments in CHICSi, a large solid angle multitelescope system mounted inside an ultra-high vacuum (UHV), cluster-jet target chamber. CHICSi performs nuclear reaction experiments at storage rings. The telescopes consist of a first very thin, 10-14 mum Si detector, a second 300 mum (or possibly 500 pm) ion implanted Si detector s
Results are reported for biosensors based on two different preparations of the same enzyme, laccase from Cerrena unicolor, one lyophilized and one stored frozen at - 18degreesC, for monitoring phenolic compounds. The enzyme was adsorbed on graphite electrodes and these were used in a flow through wall jet cell connected to a flow injection set-up. The electrodes were used at - 50 mV vs. AgAgCl. Th
A cultivation strategy combining the advantages of temperature-limited fed-batch and probing feeding control is presented. The technique was evaluated in fed-batch cultivations with E. coli BL21(DE3) producing xylanase in a 3 liter bioreactor. A 20% increase in cell mass was achieved and the usual decrease in specific enzyme activity normally observed during the late production phase was diminishe
Small-angle two-particle correlation functions, involving neutrons and protons, have been measured for E/A = 61 MeV Ar + Sn-112,Sn-124 collisions, i.e. systems similar in size but with different isospin asymmetry. The correlation strength of neutron-proton (np) and proton-proton (pp) pairs is stronger for the more neutron-rich system, indicating a shorter average emission time for this system. Com
The thesis deals with determination of the post peak behaviour of wood in pure tension and pure shear. Furhermore, the "Fictitious Crack Model" (FCM), which is a nonlinear fracture mechanics model ; originally developed for description of crack propagation in concrete, is employed to demonstrate the advantages of non linear fracture mechanics. A testing arrangement is presented with which the comp
The location of the red edge of the ZZ Ceti instability strip is definedobservationally as being the lowest temperature for which a white dwarfwith a H-rich atmosphere (DA) is known to exhibit periodic brightnessvariations. Whether this cut-off in flux variations is actually due to acessation of pulsation or merely due to the attenuation of anyvariations by the convection zone, rendering them invi
Background Open abdomen (OA) treatment often results in difficulties in closing the abdomen. Highest closure rates are seen with the vacuum-assisted wound closure (VAWC) technique. However, we have experienced occasional failures with this technique in cases with severe visceral swelling needing longer treatment periods with open abdomen. Feasibility and short-term outcome of a novel combination o
Extraction systems for hydrophobically tagged proteins have been developed based on phase separation in aqueous solutions of non-ionic detergents and polymers. The systems have earlier only been applied for separation of membrane proteins. Here, we examine the partitioning and purification of the amphiphilic fusion protein endoglucanase I(core)-hydrophobin I (EGI(core)-HFBI) from culture filtrate
Climate migration is a global phenomenon that arises as a result of climate change. This thesis discusses the emergence of climate migration and what Sweden's contingency plan is for managing external climate migration in the future. The purpose of the thesis is to investigate Sweden's preventive work against international climate migration, and then the topic of climate justice and above
How does anti-tourism affect support for the EU? This question has gained a newly found relevance in recent years, as anti-tourism protests have appeared in many European cities with high levels of tourism. Despite this relevance, some elements of these protests have not received as much attention as they deserve. This thesis will aim to fill one of the gaps in the literature: how anti-tourism soc
Practitioners primarily utilise nonparametric methods when estimating Value-at- Risk (VaR) and Expected Shortfall (ES) for computing capital requirements. However, various researchers assert that there are issues with those estimates, particularly amidst periods of market turmoil. Academia produces novel parametric methods to estimate extreme risk measures to address these deficiencies. Neverthele
The number of supply chain disruptions has increased over the last couple of years. The Covid-19 Pandemic, blockage of the Suez Canal and Russian invasion of Ukraine are some well-known examples of disruptions. Academia seems to have noticed the increasing disruptions and has explored proactive Supply Chain Risk Management (SCRM) as an approach to address this. Consulting firms also suggest compan
Due to a combination of economic challenges as well as uncertain policy conditions in the United States and the European Union, the development of (advanced) biorefineries has been slower than anticipated. This has hampered the transition to a more sustainable and less carbon-intensive economy, namely the bioeconomy. In this thesis, the technological innovation system (TIS) approach is combined wi
Purpose: This article explores the relation between brands and the use of art, and in which way art helps brands in expressing their values and identity. Furthermore, this article will identify the components that characterize Artistic Brands and Brands with Art. Design/Method/Approach: A qualitative approach will be used, and data will be drawn from six different case studies of brands collaborat
The occurrence of climate change will have a significant impact on society and adapting to a more sustainable environment is of key importance. The dangers of climate change will include temperature and precipitation patterns becoming more extreme creating a substantial impact on society. Greece’s location and climate make it particularly vulnerable to a changing climate and climate impact assessm
The present work describes the development of a novel direct screening method, assayed in 96-well format, for evaluation of enzymatic alkyl glycoside production in a hexanol water two-phase system. Alkyl glycosides are surfactants with a range of applications and with good biodegradability and low toxicity. Enzymatic synthesis makes it possible to prepare beta-D-glucopyranosides with high purity.
The purpose of this study was to determine long-term risk factors for substance-induced and primary psychosis after release from prison.
The genes encoding human manganese superoxide dismutase (MnSOD) and Vitreoscilla hemoglobin (VHb) were fused inframe to generate a bifunctional enzyme that possessed MnSOD and peroxidase-like activities. At neutral pH, the coupling of the SOD and peroxidase reactions revealed that the bifunctional enzyme exhibited a 2.5 times shorter transient period and a 1.67 times higher reaction rate at steady
Natural formation of organically bound chlorine is extensive in many environments. The enzymes associated with the formation of chlorinated organic matter are produced by a large variety of organisms. Little is known about the ecological role of the process, the key question being: why do microorganisms promote chlorination of organic matter? In a recent paper we discuss whether organic matter chl
Purpose As pediatric medulloblastoma (MB) is a relatively rare disease, it is important to extract the maximum information from trials and cohort studies. Here, a framework was developed for modeling tumor control with multiple modes of failure and time-to-progression for standard-risk MB, using published pattern of failure data. Methods and Materials Outcome data for standard-risk MB published af
