Manipulation, separation and trapping of particles and cells are very important tools in today's bioanalytical and medical field. The acoustic no-contact trapping method presented at earlier MSW 2004 provides a flexible platform for performing cell and particle assays in a perfusion-based microsystem. To further develop the system microfabricated glass channels are now used, resulting in shorter f
A framework for accurately modeling fatigue crack growth in ductile crystalline solids is necessarily multiscale The creation of new free surface occurs at the atomistic scale, where the material's cohesive strength is controlled by the local chemistry On the other hand, significant dissipation during fatigue crack growth takes place at a size scale that can be modeled appropriately by conventiona
Intentional or accidental introduction of species to new locations is predicted to result in loss of genetic variation and increase the likelihood of inbreeding, thus reducing population viability and evolutionary potential. However, multiple introductions and large founder numbers can prevent loss of genetic diversity and may therefore facilitate establishment success and range expansion. Based o
We present a comparison of experimentally and theoretically determined osmotic pressures for various colloidal dispersions. Experimental data is collected from several different silica and polystyrene dispersions. The theoretical pressure determinations are based on the primitive model combined with the cell model, and the physical quantities are calculated exactly using Monte Carlo simulations in
The Boston Psychiatric Rehabilitation Approach (BPR) is person-centered and characterized by being based entirely on the individual's unique needs and preferences in the areas of working, learning, social contacts, and living environment. Nevertheless, the person-centered approach is lacking firm evidence regarding outcomes, and empirical studies regarding clients' experiences of this particular m
The literature on universities' contributions to regional development is broad and diverse. A precise understanding of how regions may draw advantages from various university activities and the role of public policy institutions in promoting such activities is still missing. The aim of this paper is to provide a framework for analysing universities' contributions to regional economic and societal
By incorporating magnetism into semiconductors, it may possibly be viable to enhance the functionality of materials. An exceptionally important material in this context is GaAs, which can be doped with Mn atoms. (GaMn)As has fascinated research community as a promising candidate for spintronic application. It is quite appealing due to both its compatibility with existing III-V technology and great
The intermetallic compound Cu3Sn has previously been described as a long-period antiphase boundary superstructure of the Cu3Ti structure type. While the compound itself has been reported as a tenfold and an eightfold superstructure, ternary doped alloys show shorter repetitions. Interestingly, the diffraction patterns of these compounds show non-crystallographic absences that cannot be explained u
The menisci are internal structures that are of central importance for a healthy knee joint; they have a key role in the structural progression of knee osteoarthritis (OA), and the risk of the disease dramatically increases if they are damaged by injury or degenerative processes. Meniscus damage might be considered a signifying feature of incipient OA in middle-aged and elderly people. As approxim
Exoplanets have been observed at many stages of their host star's life, including the main-sequence (MS), subgiant and red giant branch stages. Also, polluted white dwarfs (WDs) likely represent dynamically active systems at late times. Here, we perform three-body simulations which include realistic post-MS stellar mass-loss and span the entire lifetime of exosystems with two massive planets, from
This master thesis explores four television plays written and directed by Samuel Beckett: Eh Joe, Ghost Trio, ...but the clouds..., and Night and Dreams. The plays are read in accordance with the film-philosophical approach to cinema outlined in Gilles Deleuze's books on cinema. The master thesis attempts to position these plays as images in relation to the movement- and time-image as well as to t
Background and purpose Can an increased focus on values in working life be a factor in stress prevention? Values are defined as the shared principles which guide behaviour in an organisation. The purpose of this study was to describe how patients with musculoskeletal pain perceive the importance of values in relation to coping with daily stress and in relation to health. Methods Patients receivi
The article investigates the notion of 'Christian Europe' by tracing some of its ideological roots. In particular, it engages with the Romantic era of German philosophy. If the idea of Europe from its very earliest stage was closely linked to Christianity, this gesture also became an important element in the attempts of a number of Romantic poets and philosophers to seek the foundations for a new
A classroom guide to teaching the case, “The Swedish Academy #MeToo Scandal and the Reputation of the Nobel Prize” (HBS No. 5-919-410). A fictional case protagonist must present his evaluation to the Nobel Foundation of the scandal affecting one of the Nobel independent network members and its implications for the Foundation. Key issues include the reputational effects of the Swedish Academy scand
Ammonium-nitrogen (NH4+) nutrition is linked to metabolic over-reduction for plants. The characteristic symptom of sole NH4+ nutrition is growth suppression, signifying this condition as the ammonium syndrome. In the present study, we investigated the mechanism of perception of high NH4+ conditions in Arabidopsis thaliana plants by examining apoplastic reactive oxygen species (ROS) metabolism. Maj
Many important scientific questions in physics, chemistry and biology rely on high-speed optical imaging techniques for their investigations. These techniques are either passive, relying on the rapid readout of photoactive elements, or active, relying on the illumination properties of specially designed pulse trains. Currently, MHz imaging speeds are difficult to realize; passive methods, being di
By a combination of Monte Carlo simulations and analytical calculations, we investigate the effective interactions between highly charged planar interfaces, neutralized by mobile counterions (salt-free system). While most previous analysis have focused on pointlike counterions, we treat them as charged hard spheres. We thus work out the fate of like-charge attraction when steric effects are at wor
Quantitative measurements of blood flow based on magnetic resonance imaging (MRI) using conventional multiple spin echo sequences were evalutated in vivo in healthy young volunteers. Blood flow was measured using MRI in the femoral vein. The initial slope of the multiple spin echo decay curve, corrected for the T2 decay of non-flowing blood was used to calculate the blood flow. As a reference, the
