As our way of living exploits the resources of the earth and our energy use keeps on increasing, we are now facing a climate crisis never seen before in modern time. To face these consequences and try to ease the harm we need to transform our extraction and use of energy. The use of chemical energy carriers and fuel cells offers the possibility of a completely green solution for energy distributio

This thesis investigates whether freely available, coarse-resolution, Passive Microwave Remote Sensing (PMRS) data (37 GHz) can be effectively used for early warning systems for floods in Malawi. The Shire River Basin in Chikwawa and the smaller-scale North Rukuru River Basin in Karonga were studied using two alternative, ratio-based satellite indices that make use of the signal difference between

The aim of this thesis is to study the self-images built on the social media Instagram by the re-elected Mayor Ko Wen-je and the second place Ting Shou-chung in 2018 Taipei mayoral election. Through conducting a qualitative content analysis as the research method and applying Goffman’s dramaturgy theory as the theoretical framework to analyse every Ko and Ting’s Instagram posting in the duration o

The archival sector of today is geared towards the public more than ever before. Students are now expected to actively participate in a process of life-long learning, to be more conscious about their cultural heritage and to develop an awareness of history. They shall also be able to evaluate different kinds of sources and approach source material critically. The Anglo-Saxon archives are internati

Background: Leading the way in developing digital surveillance camera systems Axis Communications has experienced remarkable growth during the last decade and is now considered the industry leader. Maintaining the core value of high quality is challenging with ever-increasing volumes and a high rate of new product introductions. To find and resolve issues with new products, and ensure a smooth tra

Pollen-based quantitative vegetation reconstructions using multiple sedimentary basins from the same area, along with their quantified relevant pollen source areas, are a powerful means to study how long-term human impact has affected vegetation and shaped the currently protected heritage landscapes at different spatial scales. Our study presents the outcome of a palynological investigation in Kar

Current food systems pose one of the greatest health and environmental challenges of the21st century. A systemic shift in the food sector can be accelerated by technologies and innovations,such as seaweed food applications. However, introducing and expanding seaweed as a food resourceinto Western markets comes with several challenges.These challenges include its microbial, chemical, and sensory qu

Popular Abstract in Swedish När vi ser oss omkring i naturen är det lätt att överväldigas av den otroliga variationen i olika former, färger och mönster som förekommer. Var kommer all denna variation ifrån? Samma fråga ställde sig Charles Darwin för mer än 150 år sedan – svaret publicerade han 1859 i sin bok ”Om arternas uppkomst”. Evolution är den process som genom selektion gynnar vissa egenskapOur knowledge of the evolutionary potential of traits involved in different selective episodes, especially in natural populations, is still limited. This is true for questions such as the genetic basis and inheritance of traits, how natural and sexual selection acts on them, and how selective conflicts influence the evolutionary response to selection. In my thesis, I investigate these questions, u

To study the role of serum testosterone (T), estradiol (E(2)), and SHBG as regulators of peak bone mass and bone turnover rate in males, a cross-sectional study with data on lifestyle factors collected retrospectively was performed in 204 young Finnish men, 18.3-20.6 yr old. One hundred fifty-four men were recruits of the Finnish Army, and 50 were men of similar age who had postponed their militar

Ovarian cancer is the seventh most common cancer in women globally, with approximately 240,000 new cases annually. Although a rare disease, it is the most lethal gynecologic malignancy. Unspecific symptoms result in late diagnosis and a generally poor prognosis. However, ovarian cancer is a heterogeneous disease comprising different disease entities, which is of importance in clinical decision-mak

The urinary bladder is responsible for storage and expulsion of urine. Proper urination depends on an ability of the bladder to adjust to increasing volume and to contract during micturition. A disturbance of bladder contractility may affect continence. In the present thesis I have used genetic, biochemical and physiological approaches to examine the role of caveolae and mircoRNAs in bladder funct

Photosynthesis is performed by a multitude of organisms, but in P nearly all cases, it is variations on a common theme: absorption of light followed by energy transfer to a reaction center where charge separation takes place, This initial form of chemical energy is stabilized by the biosynthesis of carbohydrates. To produce these energy-rich products, a substrate is needed that feeds in reductive

Amorphous Silica (ASi) is present in considerable amounts in most soils and serves as a (micro-)nutrient for many plants. However, our understanding of the response of this important nutrient pool to human or natural disturbances is still very limited. One of the reasons for this is the long time scales involved. This explorative study focuses on the effect of a historical agricultural system, cal

Problem - Skanska Industrial Solutions AB lays asphalt over a wide geographical area, and never in the same place and is also a work that is dependent on the weather. Asphalt is a product with low to no capacity to be stored. These factors contribute to a distribution that has the necessity to follow the JIT-principles. The asphalt production is in of a steady flow of asphalt being transported fro

The Swedish Transport Administration (STA) has begun to expand the two lined tracks that run between Flackarp and Arlöv to four tracks. For STA, it is of high importance to manage aspects such as climate and energy issues in big infrastructure projects, especially since they must meet certain requirements. Furthermore, when performing life cycle assessments (LCA) in projects like these, the possib

Sweden’s substantial building stock from the million programs is in need of renovations. These residential buildings were built without major attention to energy demand or architectural aesthetics. Until now, property owners have hesitated to carry out energy renovations due to the investment cost. The aim of this master thesis was to propose an energy-efficient renovation procedure whilst takin
