We present a method to produce small pitch gratings for X-ray interferometric imaging applications, allowing the phase sensitivity to be increased and/or the length of the laboratory setup to be minimized. The method is based on fabrication of high aspect ratio silicon microstructures using deep reactive ion etching (Bosch technique) of dense grating arrays and followed by conformal electroplating

Electronic coherence signatures can be directly identified in the time–frequency maps measured in two-dimensional electronic spectroscopy (2DES). Here, we demonstrate the theory and discuss the advantages of this approach via the detailed application to the fast-femtosecond beatings of a wide variety of electronic coherences in ensemble dimers of quantum dots (QDs), assembled from QDs of 3 nm in d

Chemical conversion of carbon dioxide (CO2) into value-added products is an attractive industrial process because it offers several economic and environmental advantages. This review presents advances and challenges in the CO2 and propylene oxide (PO) co-polymerization using heterogeneous catalysts to form poly (propylene carbonate) (PPC), an environmentally friendly polymer with several applicati

This text deals with the analysis of the removal of the monument to Soviet Marshal Ivan Konev from the Prague 6 district, an important part of the capital of the Czech Republic. The given monument was built during the Soviet occupation of Czechoslovakia in 1980 and removed in 2020. The primary reason for the removal was the dissatisfaction of the political representation of Prague 6 and the leader

Library assessment and external intelligence is important for tracking and improving library activities. Quality assurance and strategic planning are intricate parts in sustainably developing better and more effective services. Gothenburg University Library has implemented a process with the goal to join these activities. The process has both bottom-up and top-down features designed to generate st

Background: Evidence-based guidelines are needed for effective delivery of home oxygen therapy to appropriate patients with chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD). Methods: The multidisciplinary panel created six research questions using a modified Delphi approach. A systematic review of the literature was completed, and the Grading of Recommendations Asse

The aim of the NavMem project is to develop a mobile navigation companion for elderly persons with memory decline (MCI). The project is intended for a wide range of target users – e.g. persons with memory problems due to early dementia, stroke but also elderly persons in general. In the following we report results from studies made together with the Swedish Stroke Association. We describe the earl

Background: Alzheimer’s disease (AD) is an insidiously progressive neurodegenerative disorder that is characterized by multiple cognitive impairments and gradual loss of independence in carrying out activities of daily living (ADL). Currently, the predominant therapy for mild-to-moderate AD is cholinesterase inhibitors (ChEIs), which have been shown to have positive effects on symptoms compared wi

For developers of automotive control, prototyping and initial tests are a hassle. Commercial solutions are available but the price and especially the price/performance ratio opens the field for more cost effective solutions. Automotive rapid prototype systems seen so far are mainly processor based systems with standard interrupt driven measurement and actuation. Control systems based on high time

To manage risks in Western society is increasingly seen as a process of including the public in different deliberative and/or participatory projects. This is sometimes done via civil society organisations (CSOs) that also have a second role as gatekeepers, managing or constraining flows of knowledge and information. This paper aims to analyse the dual role of CSOs in the management of chemical ris

The purpose of this study was to investigate how different service delivery systems for assistive devices were associated with the service delivery process (SDP) and user satisfaction in two national contexts when electric powered scooters were provided. Method: The study had a follow-up design based on a consecutive inclusion of 50 Danish and 86 Norwegian adults as they were about to be provided

(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

Abstract: Nanoplasmas resulting from the ionization of nano-scale particles by intense laser pulses are typically described by quasiclassical models, where electron emission is understood to take place via thermal processes. Recently, we discovered that, following the interaction of intense near-infrared (NIR) laser pulses with molecular oxygen clusters, electron emission from nanoplasmas can also

COSMO-RS (conductor-like screening model for real solvents) and three different group-contribution methods were used to compute saturation (subcooled) liquid vapor pressures for 16 possible products of ozone-initiated α-pinene autoxidation, with elemental compositions C10H16O4-10 and C20H30O10-12. The saturation vapor pressures predicted by the different methods varied widely. COSMO-RS predicted r

The thesis discusses the licensing system of the Creative Commons from the perspective of the theory of the commons mostly as formulated by Elinor Ostrom. The work starts by describing the concepts and theory of common pool resources and regime of the commons for production and distribution of these resources. The main characteristics for successful traditional commons – efficiency, equity and sus

Ferroelektricitet upptäcktes först 1921 av professorn Joseph Valasek i kaliumnatriumtartrat, ett ämne som är mer känt som "Rochelle salt". Valasek beskrev likheten mellan ferroelektricitet och det redan då väl beskrivna ferromagnetismen. Likt ferromagnetiska material och deras permanenta magnetiska poler uppvisar ferroelektiska material en permanent elektrisk polarisation, en separation The ferroelectric tunnel junction FTJ is a rather old concept but has recently been in the spotlight for its promising properties in computer memory technology and neuromorphic computing. The device consists of a ferroelectric insulator sandwiched between two electrodes, and by polarisation switching the resistance along the heterostructure can drastically be adjusted. The optimisation possibili

Syftet med studien var att undersöka hur personlighet med utgångspunkt från Femfaktorsmodellen förhåller sig till hur en hypotetisk idealpartner uppfattas utifrån Attraction Similarity Theory och Complementary Needs Theory. I tillägg till detta gjordes en jämförelse mellan olika sexuella läggningar för att undersöka eventuella skillnader. Metoden som valdes var en kvantitativ survey-studie som förThe purpose of the study was to investigate how personality based on the The Big Five Model relates to how a hypothetical ideal partner is perceived based on Attraction Similarity Theory and Complementary Needs Theory. In addition to this, a comparison was made between different sexual orientations to investigate possible differences. The method chosen was a quantitative survey study that was dist

Under åren 1965-1974 genomfördes en omfattande bostadsproduktion i Sverige som betecknas miljonprogrammet. Då byggdes en miljon bostäder runtom i landet. Idag finns behov av att renovera dessa bostäder. I samband med det kan energisparåtgärder genomföras för att minska energianvändningen. Detta kan uppfyllas genom att åtgärda otäta väggar och byta ut äldre fönster som medför oönskade värmeförlusteIn order to maintain a good indoor environment, air pollutants such as moisture need to be removed by the ventilation. Among the Swedish Public Health Agency's general advices for ventilation and indoor environment, 3 g/m3 is a guideline value for moisture excess during winter months to not pose a risk to human health. The indoor climate parameters moisture excess, relative humidity and air va
