The effect of reaction parameters on lipase-mediated chemo-enzymatic epoxidation of linoleic acid was investigated. Hydrogen peroxide was found to have the most significant effect on the reaction rate and degree of epoxidation. Excess of hydrogen peroxide with respect to the amount of double bonds was necessary in order to yield total conversion within a short time period, as well as at temperatur
The ATLAS experiment has performed extensive searches for the electroweak production of charginos, neutralinos, and staus. This article summarizes and extends the search for electroweak supersymmetry with new analyses targeting scenarios not covered by previously published searches. New searches use vector-boson fusion production, initial-state radiation jets, and low-momentum lepton final states,
Background and objectivesDarkness is a significant barrier to children’s independent mobility (Shaw et al., 2015) affecting the perception and use of outdoor environments, making them less attractive, and increasing social fears (Cele, 2019). This literature review addresses the question of how artificial outdoor lighting may serve to provide children independent mobility after dark.Process and meBackground and objectivesDarkness is a significant barrier to children’s independent mobility (Shaw et al., 2015) affecting the perception and use of outdoor environments, making them less attractive, and increasing social fears (Cele, 2019).

The visual appearance of an object is a function of stimulus properties as well as perceptual biases imposed by the observer. The context-specific trade-off between both can be measured accurately in a perceptual judgment task, involving grouping by proximity in ambiguous dot lattices. Such grouping depends lawfully on a stimulus parameter of the dot lattices known as their aspect ratio (AR), whos
To clarify the misfire mechanism is important for stabilizing combustion in partially premixed combustion (PPC) under low load. Fuel-tracer planar laser-induced fluorescence (PLIF), formaldehyde PLIF, flame and OH* natural luminosity imaging were utilized to qualify the local equivalence ratio, low-temperature reaction and the high-temperature flame features in an optical engine. Results show that
In small systems with large fluctuations, the classical description of thermodynamics is no longer sufficient which has led to the development of stochastic thermodynamics. One important result from stochastic thermodynamics is that with measurement and feedback it is possible to use those fluctuations to extract work from a single heat bath coupled to the system. This is thanks to the connection
Swedish National Board of Housing, Building and Planning reported in "Energi i bebyggelsen"that 80 % of the detached houses in Sweden were under-ventilated, and had a flow of 0.23 l/(s·m2) on average instead of, by the code, required 0,35 l/(s·m2). Well known concerns here are lacking indoor environmental quality and a risk of moisture problems in certain rooms and in the envelope. The naturally v
Silicon pixel detectors are at the core of the current and planned upgrade of the ATLAS experiment at the LHC. Given their close proximity to the interaction point, these detectors will be exposed to an unprecedented amount of radiation over their lifetime. The current pixel detector will receive damage from non-ionizing radiation in excess of 1015 1 MeV neq/cm2, while the pixel detector designed
Although Singapore, a linguistically and ethnically diverse city–state, uses four official languages, namely Malay, Mandarin, Tamil, and English, which are supposed to enjoy equal status, there appears to be a pecking order to these languages. English seems to be the dominant language when taking into consideration the bilingual education policy, numerous campaigns promoting its use in terms of sp
Background: the European Union of Medical Specialists (UEMS-GMS) recommendations for training in Geriatric Medicine were published in 1993. The practice of Geriatric Medicine has developed considerably since then and it has therefore become necessary to update these recommendations.Methods: under the auspices of the UEMS-GMS, the European Geriatric Medicine Society (EuGMS) and the European Academy
Large software organizations with a product line development approach face many challenges regarding testing. Test managers need to make tradeoffs along three dimensions of repeated testing (abstraction level, time and product space) and consider a range of goals and constraints. In order to keep pace with the decreased development time for new products, which is enabled by the systematic reuse, s
The purpose of this study was to investigate the early alterations of retinal function, assessed with electrophysiology, in newly onset type 2 diabetes patients without vascular retinopathy. Seventeen patients with newly diagnosed type 2 diabetes (duration 7 ± 3 months), without any vascular retinopathy in fundus photographs, were examined with full-field electroretinogram (ERG) and multifocal ERG
As a social worker you often meet children that are exposed to harmful environments in one way or another. Children who grow up in these circumstances could easily be forgotten, there-fore it is vital that these children are brought to attention. In these situations it´s necessary to find which positiv measures would be benefitial for these children. The internet is an expan-sive resource due to t
Company X Equipment division is a mature organization that has experienced a desire to broaden the knowledge about the market potentials of the Canadian markets. There is also an ambition within the organization to improve the sales in Canada by exploring previously unknown market opportunities. The needs for increased knowledge are experienced both at the Canadian sales office and at the Lund hea
In conventional design of pile foundations, all loads are taken by the piles, i.e. the contact pressure between the raft and the soil is neglected. In the last decades geotechnical engineers have started to take this pressure into account in design of pile foundation. Such a foundation, where the raft and the piles interact to transfer the loads to the ground, is in this dissertation called piled
The industry of engineered nanoparticles (ENPs) has grown rapidly during the last decade, with for example carbon nanotubes (CNTs) incorporated in high-tech composites and nanosized TiO2 in sunscreens and paint. With an increased potential of human exposure to these novel ENPs, especially during production and handling of nanoparticles, the concern of risks when people become exposed has increased
This is a project in product development made for ASSA ABLOY Entrance Systems which is a manufacturer of sliding doors among other products. The objective of this project is to come up with a solution which offers an improved air sealing capability for a set of sliding doors all while the friction remains either the same or lower compared to before. The development process began with collecting in
Civilrättsliga processregler aktualiseras i samtliga tvistemål i allmän domstol och utgör därför en central del av den svenska rättsordningen. Ofta utvecklas reglerna i doktrin och genom praxis. Den successiva relevansens princip har fått en tydlig innebörd i och med NJA 2019 s. 802 och påverkar även andra processrättsliga regler som åberopsbördan. Uppsatsens syfte är att utreda innebörden av desProcedural rules in civil law are relevant in all civil law cases in public court and are therefore a central part of the Swedish legal system. Often these rules are developed in legal science and by court practice. The principle of succes-sive relevance has gotten a clear meaning through NJA 2019 s. 802 and fur-ther affects other procedural rules such as the burden of call. The purpose of the es
Artificial neural networks are, again, on the rise. The decreasing costs of computing power and the availability of big data together with advancements of neural network theory have made this possible. In this thesis, LSTM (long short-term memory) recurrent neural networks are used in order to perform financial time series forecasting on return data of three stock indices. The indices are S&P
