It is well documented that invasive species could have significant impacts on the native ecosystem in its introduced range. Recently the Baltic Sea has been invaded by the North American Harris mud crab, Rhithropanopeus harrisii (Gould 1841). This crab could potentially have big impacts on the ecosystem since there is a lack of crabs in the Baltic Sea. This study aimed to evaluate what impacts R.
is an important area of study with implications for pharmaceutical development. Asymmetric catalysis is one way to perform enantioenriched products. To study this subject, enantiomerically pure Rh(I) complexes were synthesized to be applied as catalysts in these kinds of reactions. A new C2 symmetric dibenzo[a,e]cyclooctatetraene-ligand, 5,11-bis(3,5-bis(trifluoromethyl)phenyl dibenzo[a,e]cyclooc
This thesis aims to investigate the use of the Chilean voseo, which is a special form of the more broadly used voseo, a type of treatment that is used in many of the Spanish speaking countries on the American continent. The aim of this thesis is to investigate in which context and what parts of the interviews the voseo is used, in contrast to the more established form of treatment, tuteo. The rese
A particle accelerator consists of a large number of components, which among other things includes several acceleration modules, which consists of one or several cavities. A cavity is a complex and essential part in the accelerations process and is usually made of oxygen-free copper (OFC) or niobium. These two materials are special when it comes to metal cutting, it´s hard to find information abou
Sustainability is frequently communicated throughout the society as it’s perceived to represent something positive and desirable. Sustainable actions are supposed to serve for the good of society but the fact that the term is difficult to comprehend is problematic. Multinational corporations can adjust the term after their own intentions and aims, rather than aligned with what sustainability shoul
Since the year 2000, achieving the Millennium Development Goals (MDGs) has become the central focus of the international community. Using an empowerment framework, this study assessed the impacts of the four projects associated with Poverty Reduction Strategy Papers (PRSPs) or its Nigerian blueprint, National Economic Empowerment and Development Strategy (NEEDS). It gathered data with semi-structu
The aim of this master thesis is to evaluate energy balances for the production of liquid biogas, LBG.LBG can be produced in two main ways and these are by means; cryogenic upgrading technology andconventional technologies connected with a small-scale liquefaction plant. A third alternative is to injectbiogas into the gas grid and then liquefy a part-flow at a pressure letdown station.The cryogeni
For Chinese economy, the relationship between ownership and company performance is an important theoretical and practical topic. My research question is how ownership affect company performance and what is the basis determinant. In the view of macro, it relates to whether the economy system need further reform or not and if the economy could remain a sustainable growth. In the view of micro, it re
Recent high quality printers pose interesting questions on how to reproduce images taken by a video camera. A modern ink jet plotter has typically a resolution four times better than a good video camera. Pixel replication and bilinear interpolation give reasonable results, but have a tendency to blur the image. In contrast to these blurring phenomena, it is well known that the apparent visual qual
With the increasing importance accorded to environmental performance of buildings, the goal of this master thesis is to study the Dutch assessment method for evaluating the environmental impact caused by the material of an office building project with the Dutch version of the BREEAM certification scheme. After doing a literature review to comprehend the current state of affair concerning the asse
The aggregation of proteins into amyloid fibrils via erroneous folding, also known as misfolding, occurs in several diseases. As a consequence, the study of the kinetics and thermodynamics of this process is currently intensely pursued. Here, we study a minimalistic lattice-based model for amyloid formation using Monte Carlo techniques to sample the grand canonical ensemble, where the chemical pot
The 2008 Global Financial Crisis has come and gone. Since then, worldwide interest rates remain at an all-time low, yet economic growth remains sluggish. Theories have been put forward to explain the phenomena, two of which take a secular perspective, detached from the recent crisis. This paper employs an explorative style of examining two historical datasets with the staging point of the real int
The cell phone industry is one of the most linear sectors, which means high resource consumption in the production of telephones and difficulties in repair. In addition, only 10-12% take-back of used units takes place, the rest are often forgotten in drawers or handled incorrectly. An interesting area of research is how companies can make their choices to reduce the life cycle environmental impact
Coastal floodplains are at risk for combined high discharge and sea level events. Consequences when they occur can be several magnitudes greater than the impact from any isolated event. In this thesis the compounding of different river and coastal flood combinations at three case study sites were studied through the use of 1D/2D-hydraulic modelling software LISFLOOD- FP. The areas were; Henån, Äng
This study aims to examine how local governments originated from the global South, through Urban Food System Strategies (UFSS), are realizing global sustainability priorities as outlined by the Sustainable Development Goals (SDGs). This study is based on the policy analysis of three Latin American UFSS, with the aim to detect synergies and connections between the UFSS and the SDGs. The primary c
In this thesis, the subject of data-driven control of Unmanned Surface Vehicles (USVs) is explored. The control task is formulated through Nonlinear Model Predictive Path Following Control (NMPFC). System identification (SYSID) and Reinforcement Learning (RL) are employed to improve performance in a data-driven manner. The objectives were to assess the resulting controller’s path-following ability
The first-past-the-post electoral system employed in British general elections has remained virtually unchanged for over a century. It is therefore of historical relevance that a referendum on the Alternative Vote is planned for May 2011. This report sets out to explain why the Liberal Democrats were more successful in pushing for electoral reform after the UK general election 2010 than the Libera
An attempt to assemble play and dissociation through their common base, attachment, is presented. The Adult Playfulness Scale (APS) was given to 60 university students whereby eight with high scores on the APS and nine with low scores on the APS were selected for the second part of the study. The subjects completed the Dissociation Experience Scale C (DES-C), the Depression Anxiety Stress-Scale (D
Brain-machine interfaces are expected to play an important role in medicine – if a sustainable solution can be found – and so this study was performed to determine the biocompatibility of the photoresist SU-8 as well as a thin film needle design.This was done by histochemical staining with a collection of antibodies and mass spectrometry. The staining was performed on the perfused brains of four r
