The thermal effects related to wearing a bicycle helmet are complex and different studies have investigated single parts of this topic. A literature review was produced and published (Bogerd et al., 2015) summarizing the different findings to give a complete overview on this topic as well as to suggest new perspectives. Headgear increases head insulation and therefore is mainly problematic under w

Popular Abstract in Swedish En central frågeställning inom ekologin handlar om hur och varför organismers utbredning och antal varierar i tid och rum. Detta forskningsfält går under namnet populationsdynamik och är ämnet för min avhandling. Populationsdynamik handlar om mönster, slumpmässighet, förändringar; helt enkelt matematik! Av den anledningen är det inte bara önskvärt, utan faktiskt nödvändPopulation dynamics in space and time are manifested as changes in the distribution and abundance of organisms. To couple such patterns to the underlying processes is a central question in ecology and also key to successful management. In this thesis, I use theoretical models as well as time series data to analyze population dynamics in environments that are variable in space or time. An example o

It is the aim of this thesis to contribute to a research-based understanding of researchers’ use of blogs as a part of scholarly communication. The following research questions guide the investigation: (1) How are scholarly blogs constructed and used as sociotechnical systems in scholarly communication? (2) Which roles do scholarly blogs play in relation to other forms of scholarly communicati

Accumulated carbon uptake, apparent quantum yield (AQY) and light-saturated net CO2 assimilation (A(sat)) were used to assess the responses of photosynthesis to environmental conditions during spring for three consecutive years. Whole-tree chambers were used to expose 40-year-old field-grown Norway spruce trees in northern Sweden to an elevated atmospheric CO2 concentration, [CO2], of 700 mu mol C

Popular AbstractDenna rättssociologiska avhandling studerar "law in progress" genom att undersöka de normbildningsprocesser som framkommer i en interaktion mellan aktörer över tid. Avhandlingen har en empirisk utgångspunkt och illustrerar dessa processer utifrån ett empiriskt exempel, ett Europeiskt "Earth Observation" (EO) initiativ: Global Monitoring for Environment and Security (GMES). AvhandliThis PhD-thesis in Sociology of Law studies ”Law in Progress” by investigating norm-generating processes, which emerge through an interaction between actors over time. The thesis has an empirical approach, thus illustrates these processes through an empirical example, a European “Earth Observation” (EO) initiative: Global Monitoring for Environment and Security (GMES). The main research questions

Popular Abstract in Swedish Den dramatiska samhällsomvandlingen i Öst- och Centraleuropa 1989-91 förändrade radikalt förutsättningarna för Europas politiska och ekonomiska liv. Den politiska och militära uppdelningen upphörde, gamla stater föll sönder och nya tillkom. I vårt närområde, Östersjöområdet, har förändringarna varit mer genomgripande än på många andra håll. Interaktionen mellan områdetsThe geopolitical transformation after 1989 had radical territorial consequences in almost all parts of East-Central Europe. In the Baltic Sea Area alone, five new states were formed. The process of European integration became a priotity on the agenda. The concept of integration describes a process of uniting two or more entities. Interaction (flows of goods, people and messages) must be seen as a

Popular Abstract in Swedish Författaren utarbetar och försvarar en version av kantiansk etik som utgår från Kants tanke att det enda som har absolut värde är den goda viljan och att det högsta goda för människor därmed består i dygd samt lycka i proportion till dygd. Avhandlingen består av två huvudsakliga delar, dels en allmän genomgång av vad det innebär att vara en person, dvs en varelse som inThis work seeks to develop a Kantian ethical theory in terms of a general ontology of values and norms together with a metaphysics of the person that makes sense of this ontology. It takes as its starting point Kant’s assertion that a good will is the only thing that has an unconditioned value and his accompanying view that the highest good consists in virtue and happiness in proportion to virtue.

This doctoral thesis is comprised of five parts in the field of biomedical signal processing with focus on methods for use in hemodialysis as well as in cardiac applications. The problem of predicting hypotension is the main concern in the parts were data from patients undergoing hemodialysis are used. In Part I, a newly developed method for heart rate variability (HRV) analysis in the presence of

Popular Abstract in Swedish Varför är arbetslösheten bland ungdomar i Sverige tre gånger högre än arbetslösheten bland 25-64 åringar? Har kontakter och nätverk betydelse för ungdomsarbetslösheten? Den tes som drivs i denna avhandling menar att kontakter i form av överbryggande socialt kapital har betydelse för ungdomars möjlighet att få jobb och att ungdomars brist på socialt kapital leder till atYouth unemployment in Sweden has reached record levels during the first decade of the 21st century. In 1970, the unemployment rate for 20-24 year olds was approximately 2%. Now, forty years later, this rate has risen to 20%. Relative youth unemployment (youth unemployment in relation to unemployment for the 25-64 year olds) has also risen. Today, the unem¬ployment rate for 20-24 year olds is three

To model aerosol-cloud interactions in general circulation models (GCMs), a prognostic cloud scheme of cloud liquid water and amount is expanded to include droplet number concentration (N(d)) in a way that allows them to be calculated using the same large-scale and convective updraft velocity field. In the scheme, the evolution of droplets fully interacts with the model meteorology. An explicit tr

The aim of this study is to extend the traffic safety assessment concept to also include normal road user behaviour, thus not only exceptional behaviours such as accidents and serious conflicts. The goal is to provide a framework for a more thorough description and analysis of safety related road user behaviour in order to better understand the traffic safety processes. The traffic safety process

Competence in supply chain management (SCM) is a key factor for achieving superior business performance. The top 25 companies identified as having excellent competence in SCM in the annual research reports by AMR Research/Gartner have displayed substantially higher financial results than their competitors. In line with this cognizance, human resources are increasingly viewed as enablers of SCM and

Breast cancer is one of the most common cancers in women. It is most commonly treated by the surgical removal of the tumour in combination with (neo)-adjuvant therapy (hormone, chemo- or radio- therapy before or after surgery). However, a large number of patients are over treated, with approximately 60% being given adjuvant therapy when already cured by surgery alone. This causes many undesirable

Traditionally, automatic control techniques arose due to need for automation in mechanical systems. These techniques rely on robust mathematical modelling of physical systems with the goal to drive their behaviour to desired set-points. Decades of research have successfully automated, optimized, and ensured safety of a wide variety of mechanical systems. Recent advancement in digital technology ha

Design: A retrospective observational database study. Setting: Routine primary health care registration networks in Belgium, the Ne

Hydrogen embrittlement is often a catastrophic phenomenon of machine elements failure under cyclic stresses. This hydrogen is generated as a result of tribo-chemical and mechanical actions on the working surfaces. This hydrogen can have three different zones or stages of behaviour under tribo-mechanical actions. Firstly, it can strongly adsorb on the mating surfaces at a shallow subsurface zone an

This research explores how blue-green solutions (BGS) take part in various everyday situations in the Augustenborg neighborhood of Malmö, Sweden, where BGS were introduced over twenty years ago to control urban flooding. The research applies a relational perspective, looking at everyday life as something that is contextually formed and given meaning in relation to the socio-materiality of the envi

Wood is a porous, hygroscopic material that can take up water both within cell walls (cell-wall water) and in the macrovoid structure (capillary water). Therefore, moisture transport in wood occurs through multiple pathways and phases of water, that is, both cell-wall water, liquid water, and water vapor can be transported through the material structure. The amount of water in wood is quantified b
