Public transportation gets paralyzed every year when winter conditions occur and the purpose of this thesis has been to summarize experiences from tram cities, mainly in Scandinavia, and suggest solutions to the problems identified. Material was collected from Stockholm, Gothenburg, Norrköping, Oslo, Trondheim, Helsinki and Budapest. Operating the tramway during winter leads to problems specific t
En studie utförd för att kartlägga en eventuell korrelation mellan ett varumärke på B2B-marknaden och en större benägenhet hos kunderna till fallföretaget att förlänga sin affärsrelation.
This project (Enzymatic degradation of arabinoxylan and phytic acid as a method to increase yield and bioavailability of nutrients in liquid oat base) evaluates the degradation of phytic acid, of the insoluble fraction from Oatly’s existing production process, with the aim of increasing available nutrients such as minerals and proteins. Previous studies have shown that phytic acid from this fracti
The Great East Japan earthquake and tsunami hit coastal cities in Iwate, Miyagi and Fukushima Prefectures of Tohoku Region devastating the energy supply system in the region. Following electricity outage and fuel shortages caused severe problems in the city of Kamaishi varying from lack of mobility, communication, heating to reduced health conditions. It is important to build resilience of commun
Sysav incinerates more than half a million ton of waste every year. A metallic fraction is filtered out from the material that is left after the incineration. This metallic fraction is then divided into one part containing larger objects and one part containing smaller objects. The latter fraction is hard to sell and gives rise to problems with dust at the site of storage. Since the fraction most
Röstvilans funktion och effekt är något som under de senaste åren har ifrågasatts allt mer. Syftet med den här studien är att undersöka om det finns någon skillnad när det gäller sjukskrivningslängd och patientens upplevelser av den postoperativa tiden, mellan patienter som har ordinerats röstvila respektive patienter som tillåtits tala direkt postoperativt. Beslut togs om att enbart ta med patien
The present study adds to the sparse published Swedish literature on the performance of the Fama and French Three-Factor model on the Swedish stock market. The ability of the model to measure the cost of equity is compared with that of the CAPM. The tests are conducted in time periods with and without financial turmoil. The Fama and French Three-Factor Model is found to provide improved explanator
This thesis investigates local civil society organizations in Bosnia-Herzegovina (BiH) and their perceptions on what human rights are, what causes human rights abuses and human rights violations in BiH, and what role they perceive themselves to have in transforming the current human rights situation. The methodology used was semi-structured interviews collected in the field and later explored wit
“Porn is not for girls” – a qualitative study concerning how pornography affect young women in shaping their identities The aim of this study is to enrich the understanding of how pornography affects young women. What does it mean to be female? How do young women relate and communicate about pornography? What kind of influence does pornography have on young women’s identity development? Is pornog
Background: The individual contribution of genes in the HLA region to the risk of developing type 1 diabetes (T1D) is confounded by the high linkage disequilibrium (LD) in this region. Using a novel approach we have combined genetic association data with information on functional protein-protein interactions to elucidate risk independent of LD and to place the genetic association into a functional
In recent years, the mutational status of the KRAS oncogene has become incorporated into standard medical care as a predictive marker for therapeutic decisions related to patients with metastasized colorectal cancer. This is necessary, because these patients benefit from epidermal growth factor receptor (EGFR)-targeted therapy with increased progression-free survival only if the tumor does not car
The World Health Organization has a standardized tool to assess surgical capacity in low- and middle-income countries (LMICs), but it is often resource- and time-intensive. There currently exists no simple, evidence-based measure of surgical capacity in these settings. The proportion of cesarean deliveries in regard to the total operations (C/O ratio) has been suggested as a way to assess quickly
A search is presented for a high-mass Higgs boson in the , , , and decay modes using the ATLAS detector at the CERN Large Hadron Collider. The search uses proton-proton collision data at a centre-of-mass energy of 8 TeV corresponding to an integrated luminosity of 20.3 fb. The results of the search are interpreted in the scenario of a heavy Higgs boson with a width that is small compared with the
Purpose: To what extent active surveillance and deferred treatment for localized risk prostate cancer are used is unclear. We assessed the use of surveillance and of deferred treatment in a population based, nationwide cohort in Sweden. Materials and Methods: In the National Prostate Cancer Register of Sweden, with a 98% coverage vs the compulsory Swedish Cancer Registry, we identified 8,304 incid
Radial velocities measured from near-infrared (NIR) spectra are a potentially powerful tool to search for planets around cool stars and sub-stellar objects. However, no technique currently exists that yields NIR radial velocity precision comparable to that routinely obtained in the visible. We are carrying out an NIR radial velocity planet search program targeting a sample of the lowest-mass M dwa
We report the first experiment carried out on an in situ setup, which allows for detection of CO(2) from catalytic CO oxidation close to a model catalyst under realistic reaction conditions by the means of planar laser-induced fluorescence (PLIF) in the mid-infrared spectral range. The onset of the catalytic reaction as a function of temperature was followed by PLIF in a steady state flow reactor.
In this study doctoral students in psychology and social anthropology/ethnology were interviewed as to their selection of research problem for their Ph.D. thesis. From the perspective of activity theory it is suggested that the research problem can profitably be seen as the object of activity in research. Graduate students’ selection of a research problem was analyzed as a process occurring over t
The purpose of this project was to find an understanding for why public agents working with introduction of immigrants have decided to co-operate and co-ordinate their efforts. Another purpose was to gain insights in what characterizes this co-operation. Seven interviews were made with practitioners working with these questions on national-, regional- and local levels. The material gathered in th
The essay discusses the so called perforated vessels and especially the cylindrical vessels without any bottom found in among others Skåne. The main question is whether these could be used within craftsmanship requiring high temperatures such as bronze-melting. To do this I have undertaken a number of experiments on witch this essay is based on. Three different kinds of crafts were tested: bronze-
Syftet med denna uppsats är att undersöka om staten Marocko är skyldig till att arbetande marockanska flickors rätt till utbildnings kränks genom otillräckliga åtgärder mot barnarbete i hemmet. Obligatorisk och gratis grundskoleutbildning är garanterad i marockansk lag, men denna uppsats visar att det i praktiken förekommer ekonomiska och sociala hinder för marockanska flickor att gå i skolan.
