Using protons in the MeV range as excitation source and a high resolution Si(Li) detector,X-ray emission spectroscopy is shown to be capable of analyzing many elements with Z > 15 simultaneously at the 10-12 g level. This work discusses a theoretical lower limit of detection at moderate proton energies and gives examples of possible applications: analysis of the elemental composition of air-borne

Om "Sorgen" i Vilhelm Ekelunds Melodier i skymningen 1902

Popular Abstract in Swedish Sår som inte läker utgör ett betydande problem för dem som drabbas och för sjukvården i stort. Utebliven eller defekt läkning är ofta ett led i en bakomliggande sjukdom som exempelvis diabetes, förlamningstillstånd eller olika bindvävs- och kärlsjukdomar. Förutom en mycket stor ekonomisk belastning för sjukvården, så innebär det ett stort fysiskt och psykiskt lidande föBackground: A large number of different wound coverings have been used in order to improve the wound microenvironment, and thus accelerate repair. Since almost two centuries, clinicians and researchers have developed techniques for skin transplantation. In the past several decades, growth factors have been used as tools for accelerating and modifying skin wound repair. The experimental work in thi

The aim of the study was to review studies concerning single-set and multiple-set resistance training. Twenty-six articles were found, 19 randomized controlled trials and seven studies without randomization process. Out of the 26 articles, 11 showed similar increases in strength when comparing number of sets, mostly one set compared with three sets. Eight of the articles showed a greater increase

Homogeneous Charge Compression Ignition (HCCI) combustion lacksdirect ignition timing control, instead the auto ignition depends on the operatingcondition. Since auto ignition of a homogeneous mixture is very sensitive tooperating condition a fast combustion timing control is necessary for reliableoperation, the ignition timing control design requiring appropriate modelsand system output variables

Popular Abstract in Swedish I denna avhandling har morfologin och kristallstrukturen av epitaxiellt växta nanotrådstrukturer undersökts med hjälp av svepelektronmikroskopi (SEM), transmissionselektronmikroskopi (TEM) och multi-slice (MS) simuleringar. Bland annat har vi funnit att de lamellära tvillingar som ofta observeras i III-V nanotrådar växta i B riktningarna tenderar att begränsas av enbartIn this work, the morphology and crystal structure of epitaxial semiconductor nanowire structures grown by metal-organic vapour phase epitaxy (MOVPE) are studied by electron microscopy methods. In particular, the three-dimensional structure of nanowires and nanotrees has been characterised by scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM) and multi-sli

Field experiments with ISA (Intelligent Speed Adaptation) has been carried out in the city of Debrecen, Hungary. Twenty vehicles were equipped with two kinds of ISA systems: 1) support via an active accelerator pedal and 2) warning via beep signals and flashing red light when exceeding the speed limit. Speed was continually logged in all vehicles and the test drivers were interviewed. The results

What kind of indispensable cognitive ability is needed for intelligence, sociability, communication, and technology to emerge on a habitable planet? My answer is simple: intersubjectivity. I stress the significance of intersubjectivity, of shared cognition, for extraterrestrial intelligence and interstellar communication, and argue that it is in fact crucial and indispensable for any successful in

The new library Modelica.StateGraph is a freeModelica package providing components to modeldiscrete event and reactive systems in a convenientway. It has a similar modeling power as Statecharts,but avoids some deficiencies of Statecharts by usingelements of JGrafchart and by using Modelica as an“action” language. An overview of the StateGraphlibrary is given, the available components and anapplica

Popular Abstract in Swedish Under 9 år (1989-1997) studerades individuellt märkta mindre hackspettar i ett undersökningsområde i södra Smålands ädellövskogar. De flesta studierna gjordes i 17 potentiella revir, vilka undersöktes årligen. Följningar av hackspettar försedda med radiosändare visade att fåglarna rörde sig inom ett, i medeltal, 742 ha stort hemområde under vintern. Under häckningstideOver 9 years, 116 breeding attempts made by individually marked lesser spotted woodpeckers (Dendrocopos minor) were followed in a study area in southern Sweden. The home-range area decreased from on average 742 ha in winter to a defended territory of 103 ha prior to breeding and 43 ha during nesting. The annual timing of the breeding varied between years but was each year synchronized with the bu
