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
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
Egyptology in the 19th and early 20th centuries developed simultaneously with increased imperial presence in Egypt by the European imperial powers, which would have influence on how the discipline was practised. The history of Egyptology has for this reason primarily focused on the big four – Great Britain, France, Germany and USA – and on Egypt itself. The aim of this study is to examine how Egyp
Fjärrvärme är en teknologi som har stor potential att bidra till att möjliggöra ett fossilfritt samhälle. För att uppnå denna potential, finns det dock en del förbättringar som måste göras för att förbättra fjärrvärmeverksamheten i stort, minska förlusterna från systemen och därmed öka konkurrenskraften hos fjärrvärme som teknologi. Ett flertal studier har visat att ett sätt att göra detta, och däDistrict Heating is a technology with the potential to enable a fossil-free society. However, to realize this potential, some improvements need to be made in order to improve District Heating operation at large, decrease losses in the systems, and thus increase the competitiveness of District Heating as a technology. Several have shown that a possible solution, to increase the efficiency of Distri
Abstract The blue gum psyllid, Ctenarytaina eucalypti (Homoptera: Psylloidea), is an economic threat to Eucalyptus plantations worldwide. To date, no efficient control method is available for this pest and the potential for semiochemical-based monitoring or control methods have not yet been investigated. Hence, I conducted the first study on the olfactory sense of C. eucalypti, investigating the
Abstract: Background: Breast cancer is the most common kind of cancer among women in Sweden. While the short- to mid-term survival chances are good, the long-term survival chances are poor, and a large number of women are also likely being overtreated and thus suffer from unnecessary side effects. The South Sweden Cancerome Analysis Network - Breast (SCAN-B) Initiative aims at improving breast ca
The eminent dilemma around the relationship between the increasing world population, the need of new fuel sources and environment issues has raised great awareness in the last decades. The European Parliament has set common goals such as the reduction of the greenhouse gases by 20 % by the year of 2020, followed by the requirement of at least 10 % of the fuel has to be biofuel. An adjacent issue i
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. The questions addressed are: - Does the behaviour of pharmaceutical companies in relation to traditional knowledge infringe on the right to culture of original knowledge holders? - What regulation of bioprospecting a
Over the years, technological developments and societal changes have forced companies to modify their organizing practices. Companies operating in the construction sector are no exception, but due to their project-based structure, it is more difficult to coordinate change initiatives. Indeed, the construction sector is often described as conservative and unwilling to adopt change. However, there i
Background. Persistent intolerable pain is still an unsolved issue with a huge socioeconomic impact. To develop appropriate treatments, it is crucial to understand the complex mechanisms underlying pain and how they change during sustained pain stimuli or during pathological conditions. In particular, it is essential to clarify how the endogenous analgesic centres which are present in the brain, s
Tau accumulation starts during the preclinical phase of Alzheimer's disease and is closely associated with cognitive decline. For preventive purposes, it is important to identify factors associated with tau accumulation and spread. Studying genetically identical twin-pairs may give insight into genetic and environmental contributions to tau pathology, as similarities in identical twin-pairs largel
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
Plant-based diets are the main source of nutrients for vegetarians worldwide and for low-income inhabitants of developing countries, such as in rural areas of Bolivia. These diets may contain high levels of mineral inhibitors such as phytate that impairs mineral absorption in the human gut. Low intake of minerals in combination with mineral inhibitors is a critical factor leading to mineral defici
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
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
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
