The purpose of this paper is to discuss the conceptualisation of bibliometric analyses in terms of the levels on which they are performed, adding contextual factors to the dimension where the size of the unit being analysed is considered. Based on empirical investigations of resource allocation systems and research evaluation practices, as well as the previous literature conceptualising bibliometr

Nanowires and nanotubes are very promising tools for biological applications. Their small dimensions, which are on the same length scale as many cell components, make them an ideal tool to probe and stimulate cells with minimal perturbation. Here, we present a review of our work towards using nanowires and nanotubes for biomedical applications, such as neural implant, mechanosensing, and cell tran

We make Deterministic Lateral Displacement (DLD) flexible by combining it with AC electrokinetics.

We have fabricated a silicon-glass two-phase droplet-based microfluidic system and implemented two-dimensional acoustic focusing prior to droplet generation as well as continuously throughout the whole system to increase particle detectability. Using acoustic focusing we have effectively minimized sedimentation of the encapsulated particles and thereby increased particle detectability by as much a

Direct and precise manipulation of sub-micron particles such as bacteria, platelets, organelles, microvesicles, exosomes or virus particles is challenging. We describe for the first time how acoustic streaming in the bulk can be efficiently reduced by introducing a density or compressibility gradient and that this enables focusing of 500-nm-diameter particles in a standard acoustophoresis channel.

Allt som vi ser och arbetar med i vårt vardagliga liv består av atomer. De är mycket små, omkring 10-10 meter. De syns inte med blotta ögat, utan kräver avancerade elektronmikroskop. Men atomerna själva består av ännu mindrebeståndsdelar, ett elektronmoln som kretsar kring en kärna.Atomkärnan består av neutroner och protoner och är bara cirka 10-15 meter stor. Neutroner och protoner hålls samman This thesis focusses on the results of two experiments employing Penning traps to prepare pure beams of the 213Ra ground state and 127Cd, which were then studied with the decay-spectroscopy setup TASISpec. The experiments were conducted with SHIPTRAP at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany, and JYFLTRAP at the IGISOL Accelerator Facility at the University of Jyvä

G.Fast is a new standard for fixed broadband access that aims at achieving bit rates of 1 Gb/s over short copper loops. In order to give support to simulation, design and performance evaluation tests, the G.Fast recommendation presents examples of some wiring topologies and reference loops describing configurations expected to be found in real G.Fast deployments. Our work describes results of mode

The Swedish army marched 1658 over the ice on the Danish sounds from Jutland to Zealand. An event that led to the foundation of Lund University in 1666. From the loads involved the ice thickness can be determined to have been at least 20 cm. Using data from mid-17 hundreds and forward the ice thickness of every year is computed. Large ice thickness seems to have been more common in the period mid

Svensk hälso- och sjukvård har i ett historiskt perspektiv dominerats av investeringar i specialistvård och sjukhus. Även om intresset för primärvården har ökat kvarstår många frågor om hur man bäst organiserar verksamheten och vilken betydelse primärvården har för hälso- och sjukvårdens samlade kvalitet och effektivitet. Flera internationella bedömningar pekar mot att det behövs mera grundläggandSvensk hälso- och sjukvård har i ett historiskt perspektiv dominerats av investeringar i specialistvård och sjukhus.

Background: The receptors for advanced glycation end products (RAGE) are increased in atherosclerotic plaques. Soluble (s)RAGE decreases, whereas the extracellular newly identified receptor for advanced glycation end products (EN-RAGE) increases inflammatory responses mediated by RAGE. The aims were to explore whether sRAGE, EN-RAGE and the EN-RAGE/sRAGE ratio, were associated with the use of lipi

SKA Construction phase we are now in a transition phase that hopefully will prepare us for the next challenge: start building the SKA. One of the targets of this period is to evaluate the suitability of the Taranta (proper Webjive) Suite for creating engineering User Interfaces (UIs). The Taranta suite is a framework that allows the fast creation of web UIs that directly communicate with TANGO dev

Atmosfäriska partiklar (aerosoler) finns överallt i jordens atmosfär. Masskoncentrationen av dessa varierar kraftigt beroende på i vilken miljö man mäter. I stadsluft kan man uppmäta tiotals mikrogram per kubikmeter medan man i arktiska områden uppmäter nanogram per kubikmeter. Den kolhaltiga aerosolen utgör en betydande del av atmosfärsaerosolens massa och är känd för att påverka människors och dCarbonaceous aerosols are known to affect human health negatively and to affect the climate of Earth. As specific types of aerosols originate from specific sources, it is important to know the amount of aerosols emitted from each source. Aerosol source apportionment is an important tool in mitigating air pollution and improving air quality. The subject of this thesis was the evaluation and develop
