Popular Abstract in Swedish Många forskningsprojekt inom materialvetenskap, medicin eller grundläggande fysik kräver smala strålar av laddade partiklar som fungerar som provtagare för att undersöka materiens egenskaper. Dessa partiklar kan vara protoner, elektroner lättare joner. Relativt ofta, behöver de accelereras nästan upp till ljusets hastighet för att kunna tränga in tillräckligt djupt i prLaser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments. The major problem concerning substrate is washboard. This phenomena can be limited if one can control and min

Whilst research on climatic effects on fungal populations and communities (particularly of soil and litter-specialised species) has been done extensively, empirical examples of the impacts of climate change on airborne fungi are still lacking. Using a hot-air balloon to sample fungal spores during the winters of 2022 and 2023, here, we show the effects of warmer winter temperatures on airborne fun

Leaf area index is an important metric for characterising the structure of vegetation canopies and scaling up leaf and plant processes to assess their influence on regional and global climate. Earth observation estimates of leaf area index have increased in recent decades, providing a valuable resource for monitoring vegetation changes and evaluating their representation in land surface and earth

The extent to which different magnitudes and directions of temperature fluctuations explain long-term trends in aquatic invertebrate body size is largely unknown. Using elevational gradients and paleolimnological reconstructions, we tested the hypotheses that the size of subfossil chironomid (non-biting midges) head capsules (HCs) will covary with temperature changes, with opposite morphometric ch

A searchable database of speech samples from more than 100 Swedish dialects is being established for use in research and education. Each dialect is represented by at least 12 speakers. Recordings are made of spontaneous speech as well as words and phrases elicited with a number of specific research goals in mind. This paper summarizes one of these goals, a prosodic typology for the Swedish dialect

The clitoris contributes to the normal female sexual response cycle. A significance of cyclic guanosine monophosphate (GMP) has been assumed in the control of clitoral vascular smooth muscle. As only a few investigations on the physiology of the vascular and non-vascular clitoral tissue have been carried out, knowledge on the mechanisms controlling this particular female genital organ is still vag

A biologically active protein fraction was isolated from rabbit intestine, purified by one-dimensional SDS-PAGE and stained with Coomassie Brilliant Blue. A predominant band of approximately 110-130 kDa was excised and digested in-gel with trypsin. The resulting peptides were extracted then separated by microbore reversed-phase high-performance liquid chromatography (HPLC). Mass spectrometric data

An aim of the present paper is to examine changes in the magnitude and direction of time-order effects with changes in the physical magnitude of the stimuli, overall levels of performance, and with changes in load processing capacity. Increments and decrements in performance are gauged by means of the steepness of psychometric and chronometric functions. Load processing capacity is assessed by div

Exemplifying a rather widespread attitude among Pauline scholars, it has recently been argued on the basis of Rom. 12 that Paul differed sharply from the Stoics in his moral teaching. The present article aims to show that such a claim does not hold if and when the sources of Roman Stoicism are taken into consideration. A comparison of Paul’s moral teaching in Rom. 12 and contemporary Stoic ethics
