Two lesions, actinic keratosis (AK) and squamous cell carcinoma in situ (CIS), are believed to be precursors of squamous cell carcinoma (SCC) of the skin. These lesions can serve as an excellent model system for studying genetic changes associated with the inception of skin SCC. In the present study, five such lesions of the skin, three AKs and two AK+CIS, from three patients were short-term cultu
Den här uppsatsen handlar om dopundervisning i Svenska kyrkan. Undersökningen börjar med en genomgång av hur dopundervisningen har sett ut från Jesus tid fram till idag. Därefter görs först en komparativ innehållsanalys av äldre katekeser, Luthers lilla och stora katekes samt av tre andra katekeser som företrädare för Svenska kyrkan gav ut fram till 1980-talet. I dessa undersöker jag vad de grundThe subject of this essay is the pre- and post-baptismal education in the Church of Sweden. My method of investigation is a comparative content analysis. The documents analyzed are catechisms, different documents approved by the Church of Sweden, 27 pastoral instructions about baptism, 3 pastoral instructions about confirmation and 60 so-called parish instructions (the Church Ordinance of 1999 req
Popular science summary: Non-invasive genetic monitoring of large carnivores Proper conservation planning of endangered wildlife populations is closely tied to availability of scientifically-sound abundance and distribution data. However, inquiring high quality data for rare or elusive carnivore species inhabiting remote habitats is extremely challenging. Non-invasive collection of DNA sources (
The mechanomyogram (MMG) is a mechanical oscillations observable on the surface of the skin as a muscle contracts. Measurement of the MMG utilizing contact sensors with a weight greater than 6 g has proved to interfere with the measurement. Use of optical displacement sensors without direct contact to the skin would remove this deficiency. A Michelson interferometer, an intensity shift set-up and
Sweden is striving to fulfill Vision Zero, a road traffic safety project that aims to prevent people from getting killed or seriously injured in traffic. To further improve safety and accessibility of the existing roads, widening of roads can be performed. The purpose of this thesis is to identify and summarize different variants of construction for road widening, using the existing data and exper
Research needs: Glass has been used for a long time, mostly in the window and packaging industry, but lately architects and design engineers have become more and more interested in glass as a load-bearing (building) material. It has become a challenge to use less other materials in the glass-structures or at least not to let it show too much. One area of big interest is bolt fixings. Design engine
Är en sur vattenmiljö dålig för bakterier? Bakterier finns överallt på vår planet och är bland annat viktiga för nerbrytningsprocesser i naturen. De bakterier som klassificeras som heterotrofa livnär sig genom att bryta ner döda växt-och djurdelar och omvandla detta till energi. I sjöar och vattendrag utgör dessa bakterier en central del, då de kan utnyttja resurser som är otillgängliga för andraAbstract The environmental pH is an important factor affecting bacterial physiology and function as well as community composition in soil and marine ecosystems. However, studies of the effect of pH on bacterial function in limnic systems have been scarce. Considering studies in soil where it has been conclusively confirmed that bacterial growth rates (μ) are considerably lower in a low pH environ
Sammanfattning Vi har gjort en kvalitativ studie och intervjuat individer med en tidigare missbruksproblematik och kriminellbakgrund. Alla utom en av intervjupersonerna har deltagit i ett 12-stegsprogram. Det finns hjälp att få som missbrukare genom behandling, men det är ändå inte alla som klarar av att sluta fast den hjälpen finns. Det är viktigt och intressant att undersöka varför det är så. VWe have made a qualitative study that started from interviewees with substance abuse problems. All of the interviewees have a background as criminals and addicts and three of them have participated in twelve-step program. There is treatment that is intended to support and help addicts, but it's still not all that manage to get out of their addiction. That makes it important and interesting to
Mögel som växer inomhus har påvisats orsaka ohälsa som andningsbesvär, allergi och eksem. Eftersom vi tillbringar större delen av våra liv i inomhusmiljöer är det viktigt att hitta lösningar på detta problem. Eftersom det finns mögelsporer i luften och går det inte att undvika att få in dem i våra byggnader. Det som går att göra är att förhindra sporerna från att gro. Syftet med detta projekt har Mould growing indoors has been shown to cause health problems such as respiratory disorders, allergies and eczema. Since we spend most of our lives in indoor environments, it is important to find solutions to this problem. As mould spores are present in the air one cannot avoid getting them into buildings, but it is possible to prevent the spores from germinating. The purpose of this project was t
Sandvik SRP AB in Svedala has recently made a big investment in a completely new production facility that is called Greenfield. The facility will be ready for production in 2013 and will have eleven top modern axle lathe- and vertical boring milling machines. The machines will process casting to parts for the stone crushers Sandvik SRP in Svedala manufacture. The goal with Greenfield is to get wor
An expectation in soil ecology is that a microbial communities' fungal:bacterial dominance indicates both its response to environmental change and its impact on ecosystem function. We review a selection of the increasing body of literature on this subject and assess the relevance of its expectations by examining the methods used to determine, the impact of environmental factors on, and the expecte
Popular Abstract in Swedish Biologiska organismer har en fantastisk förmåga att anpassa sig till alla möjliga miljöer. Människans aktiviteter på jorden har skapat många nya habitat för olika typer av organismer; t ex kan vissa organismer växa på sten och vertikala klippor och när människor bygger hus så kan dessa organismer flytta över till väggar och tak som blir nya biotoper att leva på. Några aBiological organisms have an incredible ability to adapt to almost any environment and the humans activities on earth have created many new habitats for different kinds of organisms. For example can certain organisms grow on rocks and vertical cliffs, and when humans started building houses with mineral based façades, some organisms found that these were new habitats to live on. Some of these expa
Two-color pump-probe measurements of the peripheral light harvesting complex LH2 of Rb.sphaeroides reveal strong temperature dependence of the annihilation rate. The experimental results were modeled via multi-exciton density matrix theory. Based on available literature data we can set an upper limit for the feasible intramolecular internal conversion rate. We show that this also restricts the pos
In this work, an on-line process for pressurised hot water extraction (PHWE) of antioxidants from plants as well as drying of the extract in one step by particle formation based on the use of supercritical carbon dioxide (SC-CO2) has been developed. This process has been called WEPO (R), water extraction and particle formation on-line. With this process, dried extracts from onion with the same com
Objectives To assess interobserver reproducibility among ultrasound experts and gynecologists in the prediction by transvaginal ultrasound of deep myometrial and cervical stromal invasion in women with endometrial cancer. Methods Sonographic videoclips of the uterine corpus and cervix of 53 women with endometrial cancer, examined preoperatively by the same ultrasound expert, were integrated into a
Postmenopausal overweight women have an increased risk of breast cancer. The link between obesity and breast cancer could be mediated through hyperinsulinemia. Insulin and insulin-like growth factor-1 (IGF-1) stimulate mammary cell proliferation in vitro, and cell proliferation is directly linked to the risk of breast cancer. Our objective was to investigate the relationship between breast cancer
Introduction: In contrast to the intake of sugar-sweetened beverages (SSBs), the evidence linking added sugar intake to the risk of cardiometabolic disease (primarily referring to cardiovascular disease and type 2 diabetes (T2D)) is contradictory. Aim: The aim of this thesis is to elucidate the role of added sugar intake in the risk for cardiometabolic diseases. To obtain further understanding of
This study describes the prevalence of hepatitisG virus (HGV) in Iceland, in blood donors and in persons with parenteral risk factors. Among 370 randomly selected Icelandic blood donors, the prevalence of HGV viraemia was 3.8%, whereas the prevalence of HGV antibodies in the same donor group was found to be 13.2%, thus indicating that at least 17% of blood donors in Iceland had previously been exp
The degradation kinetics of normal and branched chain butyrate and valerate are important in protein-fed anaerobic systems, as a number of amino acids degrade to these organic acids. Including activated and primary wastewater sludge digesters, the majority of full-scale systems digest feeds with a significant or major fraction of COD as protein. This study assesses the validity of using a common k
Several physicochemical properties have been determined for N-dodecyllactobionamide (LABA), maltose 6'-O-dodecanoate (C-12-maltose ester), and tetra(ethylene oxide) dodecyl amide (TEDAd). The increase in the flexibility of the sugar headgroup, enabling more possible molecular conformations, reduces the minimum area/molecule at the liquid-vapor interface obtained at the critical micelle concentrati
