Background: The environment where we humans live provides the fundamental requirements we need to survive – food to eat, water to drink, and air to breathe. The quality of these elements has a major impact on human health, as they can contain substances that are detrimental to health. These we call environmental pollutants. This thesis explores the effects of exposure to air pollutants in particul
Decreasing CO2 emissions in the building sector by improving energy efficiency isan essential part of the goal to reduce global CO2 emissions, as the sector accountedfor nearly 40 percent of the energy-related CO2 emissions in 2017.There are six main parameters that affect a building's energy use. These areoutdoor climate, building envelope properties, building services and energysystems, operatio
“The Covid 19 pandemic took the meetings industry from top to bottom in one move”. These were the introducing words from the CEO of a large Swedish network of meetings firms, in their annual report for 2020. In the beginning of that year, one of the most challenging crises in the history of the meetings organizations emerged. Now, two years on the pandemic has changed the conditions for the entire
The brown bear population in Scandinavia has substantially increased the last 30 years, in-creasing the probability of interactions between humans and bears. This environmental change is evident to many who live in brown bear areas and to them it is important to feel safe when engaged in nature based activities. This research project aimed to, further develop and evaluate two specific intervention
Currently biofuels have strong political support, both in the EU and Sweden. The EU has, for example, set a target for the use of renewable fuels in the transportation sector stating that all EU member states should use 10% renewable fuels for transport by 2020. Fulfilling this ambition will lead to an enormous market for biofuels during the coming decade. To avoid increasing production of biofuel
Background: Haematopoietic stem cells expressing the CD34 surface marker have been posited as a niche for Mycobacterium tuberculosis complex bacilli during latent tuberculosis infection. Our aim was to determine whether M tuberculosis complex DNA is detectable in CD34-positive peripheral blood mononuclear cells (PBMCs) isolated from asymptomatic adults living in a setting with a high tuberculosis
In nuclear medicine, radiopharmaceuticals can be administered for both diagnostic and therapeutic purposes. In recent years, there has been an increasing interest in theragnostics, a strategy that combines both diagnosis and therapy. This can be achieved by using similar radiopharmaceuticals for imaging and radionuclide therapy, which enables highly personalised disease management. One theragnosti
Streams, rivers and lakes across wide areas of the Northern hemisphere have been subject to an increase in water color over the last decades. This increase, also known as browning, is a result of rising dissolved organic matter (DOM) and iron (Fe) concentrations in the water. Over the years, browning has received ample attention due to its impact on the structure and function of freshwater ecosyst
AbstractBackground: Non-communicable diseases are the number one killer worldwide and the leading one,cardiovascular disease (CVD), is responsible for more than 30% of all deaths. CVD is a progressive disease whichalso makes it economical, easy and effective to prevent. There are many stages of CVD that ultimately can lead tocoronary atherosclerosis, measurable as coronary artery calcification (CA
Purpose: Despite the significant role of varicocele in the pathogenesis of male infertility, the impact of varicocele repair (VR) on conventional semen parameters remains controversial. Only a few systematic reviews and meta-analyses (SRMAs) have evaluated the impact of VR on sperm concentration, total motility, and progressive motility, mostly using a before-after analytic approach. No SRMA to da
The damage caused by the dramatic worldwide increase in ‘natural’ disasters is staggering, with the poor in developing countries being most at risk. Disasters make their already precarious living conditions worse, creating a vicious circle of poverty from which they find it hard to escape. To achieve sustainable poverty reduction, more and more attention has thus been given to the need to reduce d
Popular Abstract in Swedish Kontaktallergi är en vanlig orsak till eksem i arbetslivet. Ett av de viktigaste arbetsrelaterade allergenen är epoxiharts. Det allergiframkallande ämnet i det vanligaste epoxihartset visades på 1970-talet vara det ämne, diglycidyleter av bisfenol A (DGEBA), som hartset är uppbyggt av. Dessa epoxihartser är sedan decennier med i den standardserie med allergiframkallandeEpoxy resins based on bisphenol A are well-known contact allergens and often cause occupational contact allergy. The most important allergen is the monomer diglycidyl ether of bisphenol A (DGEBA). Epoxy resins of the bisphenol F-type contain 3 isomers of the diglycidyl ether of bisphenol F; p,p'-DGEBF, o,p'-DGEBF, and o,o'-DGEBF, whereas epoxy resin(s) based on bisphenol A (DGEBA-R) contain virtua
Colour vision greatly enhances the discriminatory and cognitive capabilities of visual systems and is found in a great majority of vertebrates and many invertebrates. However, colour coding visual systems are confronted with the fact that the external stimuli are ambiguous because they are subject to constant variations of luminance and spectral composition. Furthermore, the transmittance of the o
Popular Abstract in Swedish Modellsystem för metall-DNA interaktioner Med fokus på anticanceraktiva platina(II) komplex Guld är ett mytomspunnet och fascinerande ämne som ger liv. Ett påstående som kanske förvånar, eftersom guld ofta förknippas med vackra smycken och rikedom. Att guld skulle ge liv var dock en förhoppning i Kina på 600-talet f. Kr. Där använde man nämligen metalliskt guld för medReactions of trans-dicyanodichloroaurate(III) trans-dibromodicyanoaurate(III), trans-diamminedichlorogold(III), cis-diammine(aqua)chloroplatinum(II), cis-ammineaqua-(cyclohexylamine)chloroplatinum(II), chloro(terpyridine)platinum(II) and chloro-(diethylenetriaminepalldium(II) with dimethyl sulfide, thionucleosides, thionucleotides and thione- and guanine-containing 17-mer oligonucleotides have bee
Popular Abstract in Swedish Avhandlingen har flera uppgifter, som på olika sätt hör ihop. Den första uppgiften går ut på att undersöka samvetskonflikter i det svenska samhället. I denna typ av konflikt är samvete och samvetsfrihet centrala begrepp och de är viktiga för att förstå och ta ställning i konflikterna. Den andra uppgiften blir därför att undersöka och förstå begreppet samvete och ge ett The aim of this study is to describe and analyse four conflicts and two concepts. Four conflicts of conscience found in Swedish society are studied in the second chapter. 2.2 - the state’s requirement that all male citizens do military service and the citizen’s right to refuse to do military service. 2.3 - obligatory course requirements and the college student’s right to refuse participation in c
Popular Abstract in Swedish De flesta av Sveriges cirka 15000 större broar är byggda i betong. Ett problem som kan uppkomma i betongbroar är sprickor, vilka kan bidra till att minska broarnas beständighet och säkerhet. I en del broar har fler sprickor uppkommit på sydsidan än på nordsidan vilket antyder att solen har stor påverkan på dessa broar, eftersom det är den enda faktor som skiljer sig väsWhen the temperature changes in the environment the temperature will also change in a structure. Complex interactions of climate factors affect the temperature changes. When the temperature is varied in a material it will expand or contract, and movements will be produced. If the movements are prevented, stresses may be induced which can contribute to cracks in the structure. Severe cracks have be
Katedralen var en av de mest centrala institutionerna i det medeltida samhället. Kring stiftets biskop samlades den kyrkliga makten och dåtidens elit, dygnet runt firades gudstjänster och här utbildades stiftets präster. En viktig roll för livet i och kring katedralen hade domkapitlet eller katedralkapitlet, dvs det organiserade prästerskap som betjänade domkyrkan och bistod biskopen.I mitt avhandThe cathedral was one of the most important institutions in medieval Europe. The local as well as ecclesiastical elite gathered around it and its bishop; the liturgy was celebrated day and night, year after year; the cathedral served as educational institution of the clergy. The cathedral chapter, i.e. the organized clergy that served at the cathedral, played a decisive part in all this.The overar
Abstract Levels of natural radioactivity such as 222Rn (radon) and its long-lived daughters 210Pb and 210Po were measured. The radon gas was trapped on cooled charcoal filters and the long-lived daughter products sampled on fibre filters on a daily basis. In addition, short-lived progenies were followed continuously on the filters in order to achieve a time resolution of about one hour. The ave
The Thesis, which is titled ''Reform of the United Nations Security Council: A Requirement of the Times'', consists of six chapters. Chapter I, ''Overview'', begins with the very brief historical background of the United Nations, the Charter and the UNSC. The focal point in this Chapter is about the functions and powers, the reasons - both objective and subjective -
This thesis examines the impact on traditional knowledge holders' right to culture of corporate appropriation of traditional knowledge for the purpose of developing new medicines.
