Lifejackets, categorized as personal protective equipment, are subject to meticulous regulation. In Europe, the commercialization of a lifejacket necessitates its compliance with various requirements, notably the successful completion of field tests. The objective of this project is to digitally recreate the primary tests employed for product validation. The numerical simulation employs the child

Dynamic mode I fracture initiation in impact loaded single edge bend specimens with a quarter notch is investigated by numerical modelling and the results are compared with sets of experimental data from two different steel qualities. The finite element analysis include 2D (two-dimensional) plane strain, 2D plane stress and 3D models. No crack growth is included in the calculations. The impact vel

Title: Million Boost, renovation and energy upgrade of an apartment building from the old Swedish residential development. Authors: Eszter Faludi, Victor Tuvesson Tutors: Laura Liuke, Housing Development & Management, Faculty of Engineering, Lund University. Examiner: Erik Johansson, Housing Development & Management, Faculty of Engineering, Lund University. Issue: The many apartments that

The authors are intending to investigate if theoretical arguments for misalignments from compensation structures go for Swedish firms. Attempting to bring research forward, the frameworks on M&A and compensation literature will be combined to investigate the interdependence between CEO compensation and M&A behaviour. An empirical research is made utilizing a multiple panel regression stud

In recent years a lot of criticism against the main assumptions of economic modeling has come to up, this has led to physicists entering the field of economics. By applying models originally developed for physics to economics, especially finance, analyzing methods with a different approach can be used. Inspired by earthquakes Didier Sornette created a model that analyze financial market crashes. W

The thesis aims at supplementing a critique of the existing international instruments, regional responses and national legislation of the Arctic related to marine environmental protection. With this aim in view, the thesis satisfies its objective by proposing a Bipartite “Arctic Council” acting as a conglomeration of the Arctic States and the Flag States with a hybrid “Arctic treaty”, which is an

Syftet med denna tvärsnittsstudie var att undersöka barns förståelse för empatiska reaktioners relationella innebörd och om denna skiljer sig beroende på ålder, samt undersöka om samband fanns mellan denna förmåga och förmåga till socialt perspektivtagande. Undersökningen jämförde barn i grundskolans årskurs 2 (n = 15, M = 8:7 år), årskurs 5 (n = 17, M = 11:8 år) och årskurs 8 (n = 13, M = 14:10 åThis cross-sectional study explored children’s understanding of empathic reactions relational meaning and if this understanding increases with age. It also explored an association between this ability and ability for social perspective taking. Comparisons were made between second graders (n = 15, M = 8:7 years), fifth graders (n = 17, M = 11:8 years) and eighth graders (n = 13, M = 14:10 years). T

The aim of this study is to understand how crowdsourcing campaigns in an online environment can change brand perceptions and behavioral intentions of non-participating customers. Therefore, the thesis connects two major concepts. First the phenomenon of crowdsourcing will be discussed with emphasis an emphasis on its use in marketing. Then crowdsourcing will be lined to the theoretical concept of

The HIE-ISOLDE post accelerator at CERN has recently come online, en- abling the use of radioactive ion beams with energies of up to 10 MeV/u. An active target gaseous detector is under development for use in some of the experiments. The first investigation of the electron amplification stage with gas electron multipliers has been performed. To this end, a small prototype GEM detector was built an

The impact of fouling on the performance of Reverse Electrodialysis operated with highly concentrated brine is a poorly investigated area. In this work, the fouling propensity and stability of Ion Exchange Membranes (IEMs), developed by Fujifilm Manufacturing Europe BV (The Netherlands), is investigated under the condition of seawater and brine. The fouling propensity of the IEMs was depicted by t

The continuous fabrication via membrane emulsification of stable microcapsules using renewable, biodegradable biopolymer wall materials keratin and chitosan is reported here for the first time. Microcapsule formation was based on opposite charge interactions between keratin and chitosan, which formed polyelectrolyte complexes when solutions were mixed at pH 5.5. Interfacial complexation was induce

Background: Patients with oesophageal and gastric cancer face a poor prognosis and multiple symptoms and problems that negatively affect their quality of life. In view of the prognosis and extensive illness burden, an early palliative care approach is of importance.Aim: The overall aim of this thesis was to describe and compare symptoms, problems and care needs in relation to the initial treatment

In 2009, the BergaåsenWater Supply Scheme was put into operation to ensure the future drinking water supply of two municipalities in southern Sweden. Bergaåsen replaced two vulnerable water treatment plants. It was implemented in an environment that was characterized by sensitive recipients and limited access to water. This article aims to analyze how strategies were developed to meet sustainabili

A planar millimeter-wave shared-aperture array antenna is proposed and designed in this paper. By composing the substrate integrated waveguide (SIW) and the stripline, the K-band antenna is embedded inside the Ka-band antenna to achieve a smaller size and a low profile by sharing an aperture. The Ka-band antenna radiates through the parallel slot pairs on the surface of the SIW cavities with horiz

PbS quantum dots (QDs) are some of the most attractive QDs used to develop novel optoelectronic devices such as solar cells, photodetectors and biological labels. However, identifying an appropriate method to access high quality QDs with a wide size range employing lower cost, less toxic and safer precursors is not trivial. Here, we demonstrate the diffusion controlled synthesis of size-tunable Pb

Successful implementation of plasma-assisted combustion in applied thermal processes heavily relies on how the plasma can be formed as it interacts with the reactive flow and what the effects are of such a plasma on the combustion process. The current study is an experimental investigation of a plasma-assisted lifted flat methane–air flame by a nanosecond pulsed discharge at atmospheric pressure.

Background Orthognathic surgery addresses facial aesthetics and function in patients with dentofacial deformities. It is associated with changes in upper airway volume (UAV). If changes in UAV is perceived by asymptomatic patients is unclear. Purpose The purpose was to measure associations between changes in UAV and patient-reported benefits using patient-reported outcome measures (PROM). Study de
