Laminar burning velocities for methanol, ethanol, and binary and quaternary mixtures of these with isooctane and n-heptane, have been determined using the heat flux method on a flat flame adiabatic burner. Measurements were done for an equivalence ratio range between 0.7 and 1.5 and for a range of temperatures between 298 K and 358 K at atmospheric pressure. The present study expands the available
Popular Abstract in Swedish Omkring 16% av alla cancerfall i världen beräknas vara orsakade av infektioner och omkring 5% av dessa orsakas av humant papillomvirus (HPV). HPV har etablerats som orsak till livmoderhalscancer och kondylom (könsvårtor). HPV-typer som förekommer på hud har förknippats med icke-melanom hudcancer såsom skivepitelcancer (SCC) men också ofarliga hudhudförändringar som aktiAround 5% of all cancer cases worldwide are caused by human papillomavirus (HPV) which has been established as the cause of cervical cancer and genital warts (condylomas). Cutaneous HPV types have been weakly associated with non-melanoma skin lesions such as squamous cell carcinoma (SCC) and actinic keratosis (AK). We have analyzed skin and genital lesions for presence of HPV-DNA in order to searc
The micro-mechanisms of fracture in a laminate composed of an aluminium foil and a polymer film are considered in this study. The laminates as well as the individual layers, with and without premade centre-cracks, were tensile tested. Visual inspection of the broken cross-sections shows that failure occurs through localised plasticity. This leads to a decreasing and eventually vanishing cross-sect
Rheumatoid arthritis (RA) is a systemic disease not only restricted to the joints, but can also be associated with the development of extra-articular manifestations. Extra-articular RA (ExRA) is of clinical importance because of the associated morbidity and increased risk of premature mortality compared with RA patients in general. The aims of this work were to identify patients with ExRA in early
The effect of the antibiotic sulfamethoxazole (SMX) on soil bacteria was studied using two methods (leucine incorporation and Biolog plates) of estimating pollution-induced community tolerance (PICT). SMX was added to an agricultural soil in a microcosm setup. The addition of different substrates (manure and alfalfa), and a non-amended soil, were also studied over 5 weeks. PICT measurements were v
Positron emission tomography combined with computed tomography (PET/CT) is a quantitative technique used for diagnosing various diseases and for monitoring treatment response for different types of tumours. However, the accuracy of the data is limited by the spatial resolution of the system. In addition, the so-called partial volume effect (PVE) causes a blurring of image structures, which in turn
Motivation: Proteomics is the large-scale study of all the proteins found in a cell, tissue or organism. In the last few years, and thanks to the development of mass spectrometry and bioinformatics, proteomics has led the research in several fields, ranging from medicine to agriculture. In order to reconstruct the amino acid sequence de novo protein sequencing can be used. It uses the protein’s mo
This is a bachelor thesis on how requirements are communicated within projects at IKEA IT Delivery and if a common requirement tool can facilitate the communication. The question formulations of the thesis were: • How are requirements communicated within projects at IKEA IT Delivery? • How can a common tool facilitate or aggravate the communication of requirements at IKEA IT Delivery? To see patte
Measurements of the hygroscopic properties of sub-micrometer atmospheric aerosol particles were performed with hygroscopic tandem differential mobility analysers (H-TDMA) at 5 sites in the subtropical north-eastern Atlantic during the second Aerosol Characterization Experiment (ACE-2) from 16 June to 25 July 1997. Four of the sites were in the marine boundary layer and one was, at least occasional
The concern related to the environmental degradation and to the exhaustion of natural resources has induced the research on biodegradable materials obtained from renewable sources, which involves fundamental properties and general application. In this context, we have fabricated thin films of lignins, which were extracted from sugar cane bagasse via modified organosolv process using ethanol as org
In this study a novel comparison of CFD, measured data and a ID-model is presented for a Twin-scroll turbocharger turbine stage. Both full and single admission flow divisions were taken into consideration and shown to represent "on-engine" conditions in the high and low engine rpm range respectively for a heavy-duty 6-cylinder diesel engine. With this in mind, the turbine stage was evaluated for e
Through time a woman’s right to abortion has been an emotionally and morally issue all over the world. The ethical complexity of abortion questions affects individual, political, cultural and religious levels in communities. The purpose of this study was to achieve a deeper understanding of abortion contexts, and compare how abortion context appears in the Swedish and Kenyan communities from Kenya
Human trafficking is a transnational phenomenon and it has been one of the most hotly debated issues in the development agenda for the last decade. This thesis focuses the attention on the phenomenon of women trafficking for the purpose of sexual exploitation and takes as a case study the Republic of Albania. Albania has been, especially during the 90s, widely touched by the phenomenon, and since
Purpose: The aim of this study is to unravel consumer motives for enrolling in multiple programs and explore the consumer experience of multiple memberships in the highly competitive loyalty program market. Methodology: We have conducted a qualitative research with a hermeneutic approach. A sample group of nine women in the ages 47-62 were selected based on a snowball sample. Through detailed acco
Vid tunnelbygget genom Hallandsås i nordvästra Skåne har man stött på tre större vittringszoner och har periodvis haft problem med stort inflöde av vatten till tunnlarna. Detta vatten kommer från de ovan– och omkringliggande akvifärerna och dräneringen registreras som sjunkande grundvattennivåer i kontrollbrunnar på åsen. För att försöka skapa en bild av sprickakvifärernas utbredning i området ovaDuring the tunnel boring project through Hallandsås in the northwestern part of Skåne, large-scale weathering zones have been encountered and there have periodically been problems with great amounts of water leaking into the tunnels. This water comes from the above and surrounding aquifers and the drainage is registered as sinking groundwater levels in control wells on the ridge. In an attempt to
This paper examined and identifies the important determinants of Fertility decline in East Africa countries using a panel data set from world development indicator data base (WDI) for eight selected East African countries between 1998 and 2010. Panel regression methods were used to determine the impact of socioeconomic determinants on fertility. Fertility rate reduced in a slow pace during the per
The purpose of this essay was to study factors that influence some youth to use narcotics. I wanted to increase my understanding and knowledge about these factors. I believe it is good to have such knowledge when you are working with youth who are using narcotics but also for a good drug-prevented work. It is a literary study, which covers the most frequently quoted results in the field of researc
The purpose of this paper was to study the various organisations that work with drug abusing homeless people in Lund. We have tried to compare the possibilities they have to change the way the homeless people look at themselves. The organisations that we have studied are Aluma, Diakonicentralen, the shelter Piletorp and the social welfare office. The methods used to collect data were interviews w
In this study the efficiency of a pre-treatment method planned to treat wastewater produced at a waste treatment facility in Rönneholm (Skåne, Southern Sweden) was evaluated. At this waste treatment facility, operated by the publicly owned waste recycling company MERAB, a treatment is needed to lower concentrations of potentially environmentally detrimental contents in the wastewater to an extent
Photoionisation dynamics occurring in Ar and N2O upon the absorption of soft X-ray radiation, have been studied through the extraction of the beta parameter from the angular distributions of Ar 2p 3/2 and N2O Nt 1s photoelectrons by a means of Velocity Map Imaging Spectroscopy. The results of beta determined in the dipole approximation for N2O at different photon energies, coincided with pre-docu
