The study of molecular dynamics involves observations of the motion of nuclei and electrons. While nuclear motion is usually on the picosecond or femtosecond timescale, attosecond precision is necessary to directly observe the motion of electrons. Ultrashort laser pulses have become established as a viable tool for probing femtosecond dynamics by irradiating the target for only extremely short tim

This paper reports on studies of multiple-injection strategies of gaseous fuel in a model combustion chamber and the role of jet-jet interactions on the mixing processes in the chamber using large-eddy simulation (LES). A high-pressure non-reacting gas flow injected through a jet with a nozzle diameter of 1.35 mm into a quiescent inert air environment is considered. First, we validate the method a

Most large tidewater glaciers in Svalbard are known to have surged at least once in the last few hundred years. However, very little information exists on the frequency, timing or magnitude of surges prior to the Little Ice Age (LIA) maximum in ∼1900. We investigate the sediment-landform assemblages produced by multiple advances of the Nathorstbreen glacier system (NGS) in order to reconstruct its

This essay reflects on the ”-ology of technology”, pace Brian Arthur (2009), as conveyed in theformal (i.e. mathematical) treatment of technology and innovation in economic theory. In thedecades from the 1970s economists of the evolutionary strand have levied criticism on the way inwhich technology is handled in mainstream economics. Some of this criticism has concerned theassumptions made in part

The aim of this thesis is to analyse how members of the Swedish press were represented in different media from the 1870s to the 1930s, how and why the representations were changed, and the way newspaper staff responded to them. The representations of journalists in novels, short stories, movies, press history, press debates, pictures in the funny papers and so on are analyzed as parts of the publi

There has been a significant interest in the estimation of time and effort in fixing defects among both software practitioners and researchers over the past two decades. However, most of the focus has been on prediction of time and effort in resolving bugs, without much regard to predicting time needed to complete high-level requirements, a critical step in release planning. In this paper, we desc

Soil contamination is a widespread problem and actions need to be taken in order toprevent damage to the groundwater and the life around the contaminated sites. InSweden more than 80.000 sites are potentially contaminated, therefore there is ademand for accurate and efficient methods for site characterization and soilremediation. In the past, the preferred methodology for soil remediation involved

While pipe biofilms in DWDSs (drinking water distribution systems) are thought to affect the quality of distributed water, studies regarding the microbial processes are impeded by the difficulties in accessing biofilm undisturbed by DWDS maintenance. In this study, pipe sections were removed from a fully operational DWDS for biofilm sampling over two years and three months, and before and after st

In the first part of this thesis, three intermetallic compounds are discussed, that were originally thought of as thallium iodide type compounds. Starting from small evidence that there is more than meets the eye, investigations began to find the true structure of AuIn. AuIn emerged to be modulated with various domain sizes over temperatures between room temperature and 400◦C, where at room temper

This a contribution to the cultural semiotics of African cultural encounters seen through the eyes of Swedish naturalists at the end of the eighteenth century. European travellers faced severe problems in understanding the alien African cultures they encountered; they even had difficulty understanding the other culture as a culture. They were not just other cultures that they could relate to, but

This paper examines the Nordic as an ideological, cultural, and geographical site from which to examine place branding. Although a number of studies have addressed Nordic place brands and branding, the peculiarity of branding within the Nordic welfare states remains understudied (Lucarelli et al., forthcoming 2019). The unusual open access to the field of practice granted to researchers (at least

The Drosophila antenna contains receptor neurons for mechanical, olfactory, thermal, and humidity stimuli. Neurons expressing the ionotropic receptor IR40a have been implicated in the selection of an appropriate humidity range [], but although previous work indicates that insect hygroreceptors may be made up by a "triad" of neurons (with a dry-, a cold-, and a humid-air-responding cell []), IR40a

The present thesis investigated how listeners use prosody to rapidly predict upcoming lexical and syntactic structures. In the first three studies, it was shown that listeners take advantage of Swedish word-level tones to pre- activate upcoming word endings. Every Swedish word has a tone on the word stem – known as a ‘word accent’ – which is either low or high, and the tone is assigned to the stem

Contemporary debates on sustainability usually relies on standardised and normative categories, such as ‘social’ and ‘nature’, and on linear notions of time. This study explores a more complex perspective on the delicate borderlands between the ‘un-sustainable’ and the ‘sustainable’. A particular material and a particular place stand at the centre of attention: woollen Merino fibre on the South Am

Energy-intensive processing industries like the concrete industry form the base of the economy and account for a large part of global greenhouse gas emissions. Sectoral transformation to cleaner basic materials is therefore crucial, and institutional pressure to do so is increasing. However, socio-technical studies have not sufficiently addressed these sectors. This paper therefore sets out to ana

Popular Abstract in Swedish I denna avhandling studeras ledningsförmågan hos nanometer-stora kvantprickar tillverkade i halvledarmaterial. Halvledare är material vars ledningsförmåga ligger någonstans mellan ledare (metaller) och isolatorer. I halvledare kan ledningsförmågan ändras med elektriska fält, vilket har möjliggjort utvecklandet av halvledartransistorn. Utvecklandet av halvledartransistorThis thesis focuses on electron transport in single and double quantum dots defined in low-dimensional, narrow-band-gap III-V semiconductor materials. Fabrication schemes are presented for defining single and double quantum dots in lateral InGaAs/InP heterostructures, either by a combination of etching and local gating or solely by local top gating. The quantum dots are here electrostatically conf

BACKGROUND: Empirical knowledge around palliative care provision and needs of people with intellectual disabilities is extremely limited, as is the availability of research resources, including expertise and funding. This paper describes a consultation process that sought to develop an agenda for research priorities for palliative care of people with intellectual disabilities in Europe.METHODS: A

Popular Abstract in Swedish I luftvägarna finns ett sekret, "mukus" eller "slem", som tillsammans med flimmerhårens rörelser förhindrar skadliga ämnen att nå lungorna. Denna sk mukociliära transportmekanism är av yttersta vikt för vår hälsa och överproduktion av mukus tillsammans med försämrad mukociliär transport kan innebära fara för livet. Mukus innehåller till största delen vatten (95-99%) menMucus glycoproteins (mucins) are the principal constituents of respiratory secretions in health and disease. The increased 'acidity' of mucin producing cells in the bronchitic airways is not reflected in a change of negative charge of bronchitic mucins. Furthermore, the size and macromolecular properties of mucins from chronic bronchitic sputa do not differ significantly from those in normal airwa

Electrical machines, chokes and induction heaters are found in most homes,offices and factories all over the world. They are used to create movement, filtrate the power or to generate heat. A typical unit consist of a coil and a flux conductor material. Some of the materials have been established for over 100 years, while others are only a couple of decades old.A new flux conductor material has be
