Fabrication of binder-free pencil-trace electrode for lithium-ion battery : Simplicity and high performance

(Graph Presented) A binder-free and solvent-free pencil-trace electrode with intercalated clay particles (mainly SiO2) is prepared via a simple pencil-drawing process on grinded Cu substrate with rough surface and evaluated as an anode material for lithium-ion battery. The pencil-trace electrode exhibits a high reversible capacity of 672 mA h g-1 at 100 mA g-1 after 100 cycles, which can be attrib

Effects of soil resources on expression of a sexual conflict over timing of stigma receptivity in a mixed-mating plant

While environmental factors strongly influence plant growth and reproduction, less is known about environmental effects on sexual selection and sexual conflict. In this study on mixed-mating Collinsia heterophylla we investigated whether soil resource environment affected traits associated with sexual conflict. In C. heterophylla a sexual conflict over timing of stigma receptivity occurs. Early st

Försörjningskedjans framväxt och framtid

Dagens moderna samhälle är ett i många avseenden sårbart samhälle. Det har inte varit någon medveten strävan utan är en konsekvens av att samhället till stor del kommit att bli uppbyggt kring försörjningskedjor (supply chains). I dessa hårt integrerade kedjor med ett flertal ofta globalt utspridda led flyter en ständig ström av fysiska varor, tjänster samt kombinationer av varor och tjänster.I den

A new method of random environmental walking for assessing behavioral preferences for different lighting applications

Accurate assessment of people’s preferences for different outdoor lighting applications is increasingly considered important in the development of new urban environments. Here a new method of random environmental walking is proposed to complement current methods of assessing urban lighting applications, such as self-report questionnaires. The procedure involves participants repeatedly walking betw

Surface-sensitive X-ray diffraction across the pressure gap

In this chapter surface-sensitive X-ray diffraction is introduced as an important crystallographic tool for the investigation of surfaces and nanostructures under high pressure reaction conditions and elevated temperatures which are relevant for industrial catalysis. After the introduction surface-sensitive X-ray diffraction methods are briefly explained and specialized instrumentation developed f

Lock-in as make-believe : Exploring the role of myth in the lock-in of high mobility systems

All human practices are, ultimately, set and defined by limits; be they social, economic, physical, or environmental. Yet even in the face of such realities, practices which transgress the confines of possibility remain remarkably obdurate. This thesis addresses the issue of one such practice, i.e. the escalation of personal mobility across time and space which pushes above and beyond systemic bou

An independent evaluation of a new method for automated interpretation of lung scintigrams using artificial neural networks

The purpose of this study was to evaluate a new automated method for the interpretation of lung perfusion scintigrams using patients from a hospital other than that where the method was developed, and then to compare the performance of the technique against that of experienced physicians. A total of 1,087 scintigrams from patients with suspected pulmonary embolism comprised the training group. The

Delayed maximum northern European summer temperatures during the Last Interglacial as a result of Greenland Ice Sheet melt

Here we report a new quantitative mean July temperature reconstruction using non-biting midges (chironomids) from the Danish Last Interglacial (LIG) site Hollerup (spanning 127-116 ka). We find that peak mean July temperatures of 17.5 °C, similar to those of the present day (1961-1990 CE), were reached shortly before the onset of the regional Carpinus pollen zone. Through comparison to terrestrial

Surface science at the PEARL beamline of the Swiss Light Source

The Photo-Emission and Atomic Resolution Laboratory (PEARL) is a new soft X-ray beamline and surface science laboratory at the Swiss Light Source. PEARL is dedicated to the structural characterization of local bonding geometry at surfaces and interfaces of novel materials, in particular of molecular adsorbates, nanostructured surfaces, and surfaces of complex materials. The main experimental techn

Islet autoantibodies present in association with Ljungan virus infection in bank voles (Myodes glareolus) in northern Sweden

Bank voles are known reservoirs for Puumala hantavirus and probably also for Ljungan virus (LV), a suggested candidate parechovirus in type 1 diabetes etiology and pathogenesis. The aim of this study was to determine whether wild bank voles had been exposed to LV and if exposure associated to autoantibodies against insulin (IAA), glutamic acid decarboxylase 65 (GADA), or islet autoantigen-2 (IA-2A
