It has been postulated that six co-located orthogonally polarized electrical and magnetic dipoles can offer up to six degrees of freedom (DOFs) in a multipath scattering environment. In other words, a six-fold increase in channel capacity can be achieved in the context of MIMO systems. However, due to the complexity in designing and measuring such a six-port antenna, to our knowledge, no experimen
År 2011 kom det första auktoritära ”soft law” dokumentet inom området företag och mänskliga rättigheter,”UN Guiding Principles on Business and Human rights”. I detta dokument åläggs företag ett ansvar att respektera mänskliga rättigheter genom att använda sig av en s.k."human rights due diligence" (HR DD). Denna ska bl.a. innehålla en "root cause analysis" för att överensstämmaIn 2011, the UN Guiding Principles (UNGPs) became the first authoritative international standard regarding the field of business and human rights. The document states a responsibility for companies to respect human rights. The operational principle of due diligence in the UNGPs is designed as a tool for companies to use in order to be able to respect human rights. However, if the due diligence is
Researchers and practitioners have recognized the need for ‘transforming’ every policy of the company into a competitive advantage tool. Thus, both the pricing approach and the supply chain practices of the firm have emerged as an important determinant of success. In this study, however, we are not only interested in these two aspects, but also in a third one-namely cultural conflicts as an obstac
The purpose of this study was to find out why people choose to be physically inactive when only thirty minutes of exercise a day is sufficient to have a positive effect on one's health. In order to find out the reasons why people do not exercise, we conducted semistructured interviews with twenty people from Malmoe. The participants were between 23 and 63 years of age with the group consisting
Assemblies formed by a well-defined quality of DNA (4331 bp T7 DNA) and the small net-cationic protein lysozyme in dilute aqueous solutions have been characterized using cryo-transmission electron microscopy (cryo-TEM) and dynamic light scattering (DLS) as the main techniques. In a wide range of different DNA to lysozyme ratios in solutions of low ionic strength, dispersions of aggregates with the
Phase diagrams of poly(ethylene glycol)/polyacrylate/Na(2)SO(4) systems have been investigated with respect to polymer size and pH. Plasmid DNA from Escherichia coli can depending on pH and polymer molecular weight be directed to a poly(ethylene glycol) or to a polyacrylate-rich phase in an aqueous two-phase system formed by these polymers. Bovine serum albumin (BSA) and E. coli homogenate protein
Popular Abstract in English Background Palliative care is an approach characterized by a holistic view of the person, which supports the individual for living with dignity and with the best possible level of wellbeing until the end of life. Earlier studies have shown that older people do not have the same access to palliative care as younger people do. One reason for this could be that it is diffiThe aim of this thesis was to study nurse assistants’ experience of palliative care and to investigate how an intervention with a focus on a palliative care approach in residential care facilities influenced the nurse assistants and their work situation. The thesis is based on two qualitative and two quantitative studies, focusing on nurse assistants working at residential care facilities for olde
Travel in the footsteps of cinema is an expanding market, both in Sweden and internationally. Travel habits are changing, and the fact of a good number of people planning their journeys in order to follow in the footsteps of fictitiousn characters, or alternatively follow a particular route in order to experience first-hand something they saw at the cinema or on television, has become an important
The field of labour history has come to increasingly include the study of gender, a social relation that traditionally has been made invisible. At the same time the past decades of theoretical debate within gender studies and history have meant the marginalisation of class studies, at the benefit of other social relations. I wish to contribute to the field of research on the Swedish labour union m
Collaboration projects have the last decade become the new working method within the fragmented and specialised Swedish welfare sector. Collaboration aims to prevent people in need of vocational rehabilitation from ending up in between the responsible organisations. In 2004, a permanent organisation that enables local and national agencies to collaborate within vocational collaboration was made po
In this thesis we study analytical and numerical methods which describe interactions and evolution of complex physical systems modeled by microscopic processes. We focus on two types of systems which are differentiated based on how modeling is taking place at the microscopic level. In that respect we study systems which can be described either by stochastic differential equations or by elementary
The transcription factor WUSCHEL and the peptide CLAVATA3 have key roles to plat in the regulatory network effecting the differentiation of the stem cells at the shoot apical meristem of Arabidopsis. The signal pathway of this network has been under investigation for several years and models utilizing the already identified parts of the network have been developed. Such models have however so fa
Presentation of the problem: How can one optimize and make managers’ working situation more efficient in a time with more severe strain, and at the same time maintain a good psychosocial working environment? What is required to make a manager feel satisfied with his working situation, and at the same time encourage him/her to take an active part in an effective building process? Purpose: The purp
There are many empirical studies that reject the forecasting power of the uncovered interest rate parity condition. This might be due to different reasons, of which one often stated is the existence of a risk premium. In this paper three versions of the conventional UIP model are tested in order to investigate which one that generates the best predictions on the future spot rate. One model without
Vindkraft är en förnyelsebar energikälla som ligger i tiden och är den energikälla som idag växer snabbast i världen. Eftersom Sverige har stor utbredning och långa kustpartier finns det goda möjligheter att utnyttja vind som energikälla. Sveriges riksdag har därför satt ett mål att ungefär tiodubbla energiutvinningen från vindkraft till år 2015. Den generella uppfattningen om vindkraft i Sverige
Detailed information from the Swedish National Forest Inventory was used to simulate the carbon balance for Sweden by the process-based model Biome-BGC. A few shortcomings of the model were identified and solutions to those are proposed and also used in the simulations. The model was calibrated against CO2 flux data from 3 forests in central Sweden and then applied to the whole country divided int
A case study is presented in which two organisations have participated in a benchmarking initiative to discover improvement suggestions for their processes for managing product platforms. The initiative, based on an instrument which consists of a list of questions, has been developed as part of this study and contains eight major categories of questions that guide the participating organisations t
