Evolutionary genomics has recently entered a new era in the study of host-pathogen interactions. A variety of novel genomic techniques has transformed the identification, detection, and classification of both hosts and pathogens, allowing a greater resolution that helps decipher their underlying dynamics and provides novel insights into their environmental context. Nevertheless, many challenges to
There is increasing pressure on freshwater systems due to excessive nutrient loading by anthropogenic sources. In Sweden, freshwaters have become browner due to increasing exports of organic matter from soils into streams, rivers, and lakes. This study aimed at detecting temporal patterns in Total Organic Carbon (TOC) and Total Organic Nitrogen (TON) concentrations in 44 Swedish rivers, and to lin
An analysis of particle formation (PF) events over a subarctic mire in northern Sweden was performed, based on number size distributions of atmospheric aerosol particles (10-500 nm in diameter) and ions (0.4-40 nm in Tammet diameter). We present classification statistics for PF events from measurements covering the period July 2005- September 2006, with a break over the winter period. The PF event
The purpose of this study is to assemble information of costs per fatal casualty in traffic accidents, adopted by authorities in different countries. analyse and compare these figures as well as the methods used for estimating these values. A questionnaire was sent to 19 countries from which 11 gave information on cost per fatality and methods of valuation. The costs per fatality, usually defined
Popular Abstract in Swedish Fjärrvärme är en väletablerad teknik som främst används för uppvärmning av byggnader och varmvatten. I Sverige värms över 80% av flerbostadshusen med fjärrvärme, vilket innebär att de flesta svenskar faktiskt bor i ett fjärrvärmeuppvärmt hus. Fjärrvärme är inte enbart en svensk teknik, utan används över hela värden där behov av uppvärmning finns. Länderna i Norden och ÖThe objective of this thesis is to contribute to improved performance of district heating systems by focusing on three items. Item 1: Study of three methods for improving the performance of sub-systems within buildings connected to the distribution network. The methods can be considered as more or less innovative. Results from two of these measures are quantified in terms of so-called Primary Ener

In recent decades, a significant advancement in the Global Navigation Satellite System (GNSS) has been adopting the vector tracking (VT) technique, particularly in environments where stable and reliable positioning is essential. It facilitates rapid reacquisition and continuous tracking of GNSS signals by linking the data processing and signal processing modules. In challenging environments affect
Chlorophyll a concentration is a crucial indicator of marine primary productivity and its accurate prediction is vital for the early warning systems in marine ecosystem. Present work focused to examine the relationship between chlorophyll a concentration and environmental factors in Lake Vänern and to predict the chlorophyll a concentration using Random Forest model and Generalized linear model du
Climatic factors and water and land use management mainly impact dust storm frequency and intensity. Water scarcity and a drier climate will lead to more severe and frequent dust storms in the near and far future. This makes dust storm susceptibility a dynamic phenomenon requiring spatiotemporal analyses. Regarding the complexity of this phenomenon, this chapter discusses AI-based methods for spat
P. F. Strawson's 1962 essay ‘Freedom and Resentment’ has been enormously influential for the contemporary responsibility discussion. It nevertheless remains contested how the essay is to be understood, and what the central argument is, if there even is any such. In her recent book Freedom, Resentment, and the Metaphysics of Morals (2020), Pamela Hieronymi argues that what is, in fact, the central
Drylands account for a disproportionate share of the world’s armed conflicts, a pattern frequently interpreted through the lens of resource scarcity– where climate change and water stress are seen as primary drivers of violence. While this framing underscores critical environmental pressures, it risks simplifying the complex social, ecological and political realities of these regions. This article
The magnesium, calcium, strontium and barium ions bind six, eight, eight and nine water molecules in the first hydration shell, and ca. 12, 16, 16 and 18 water molecules in the second one, in dilute aqueous solution, respectively. With increasing concentration of alkaline earth metal halides, water molecules in the second hydration shell are exchanged for hydrated chloride and bromide ions forming
