The term 'synergy' - from the Greek synergia - means 'working together'. The concept of multiple elements working together towards a common goal has been extensively used in neuroscience to develop theoretical frameworks, experimental approaches, and analytical techniques to understand neural control of movement, and for applications for neuro-rehabilitation. In the past decade, roboticists have s
Difficulties in attracting student teachers have resulted in research focusing on student teachers' motives for studying to join the profession. Because previous findings are mixed, the first aim of this study was to explore motives for students to become teachers. A second aim was to explore the relationship between teachers' motives and their academic engagement and dropout rates at the end of t
Dyskinesia and motor fluctuations affect up to 90% of patients with Parkinson's disease (PD) within ten years of L-DOPA pharmacotherapy, and represent a major challenge to a successful clinical management of this disorder. There are currently two main treatment options for these complications, namely, deep brain electrical stimulation or continuous infusion of dopaminergic agents. The latter is ac
PurposeThe aim of this study was to analyse prescription refill, re-hospitalisation, total mortality, mortality because of suicide and attempted suicide among patients who were taking various types of antipsychotics. MethodsA population-based cohort study analysed all patients (n=26046) in Sweden who had been treated for schizophrenia from 2006 to 2009 with regard to re-hospitalisation and prescri
In the paper we present a research model for evaluating determinants of ERP value in small and medium-size enterprises (SMEs). The model is grounded in the diffusion of innovation (DOI) model and resource-based view of the firm (RBV) theory. The research model links six DOI determinants to explain ‘ERP use’ linked with two additional determinants to explain ‘ERP value’, on which nine hypotheses ar
The Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) in 2013–2014 was the most comprehensive analysis of anthropogenic climate change, its impacts, and potential responses. It concluded that climate change is “unequivocal” and human activities are the dominant cause. Avoidance of “dangerous” climate change will require sustained substantial reductions of emissi
Popular Abstract in Swedish Kolhydrater är viktiga inte bara som bränsle och strukturgivande egenskaper, vilket var uppfattningen för 25 år sedan. De ingår även som en mycket viktig del i hur celler kommunicerar med varandra. Det har de senaste åren visat sig vara kolhydrater inblandade i en mängd signalering- och igenkänningsmekanismer. Några exempel: när bakterier angriper en cell är det oftast Artificial, amfiphilic, and biomimetic receptors soluble in water were synthesized via attaching polar amino acids to hydrophobic back-bones possessing a surface suitable for hydrophobic interactions. The hydrophobic back-bones chosen in this thesis were anthracene and dibenzobarrelene structures. A route to an efficient synthesis of a dibenzobarrelene backbone with two sets of orthogonal reactivi
Temperature limitations of Solid Oxide Fuel Cells (SOFC) in transient single operation and steady-state Hybrid System (HS) operation with Gas Turbines (GT) are presented. For transient SOFC simulations, an unsteady-state SOFC model was developed by upgrading a detailed validated steady-state model. As critical SOFC single operation modes, concerning the risk of material cracking due to exceeding S
Popular Abstract in Swedish Allteftersom kraven på kvalité och prestanda hos dagens produkter ökar används alltmer avancerade material som en del av modern produktion. Problemet som uppstår är dock att dessa material ställer nya krav på tillverkningsprocessen och då inte minst vid skärande bearbetning. Trots att en betydande mängd forskning redan har publicerats vad gäller skärande bearbetning av As quality and performance demands on today’s products increases, more and more advanced materials are being used during modern production. The problem is however that this in turn place new demands on the machining processes utilized. Even though a significant amount of research has been published on the machining of these materials knowledge is still limited in several crucial areas. A problem w
Desalination can be a cost-effective way to produce fresh water and possibly electricity. The Gaza Strip has had a complex hydro-political situation for many years. Gaza is bordered by the Mediterranean in the west, by Israel in the north and east and by Egypt in the south. Water and electricity consumption in the Gaza Strip is expected to increase in the future due to the increasing population.
Popular Abstract in Swedish Transplantation av nervvävnad till hjärnan är inte en ny idé. Redan 1890, publiserade Thompson de första försöken att transplantera vuxen hjärnvävnad till det vuxna centrala nervsystemet och han rapporterade att vävnaden överlevde i sju veckor "without wholly losing its identity". Trots detta var det först under 1970-talet som metoderna för intracerebral nervcellstranspIntracerebral neuronal transplantation have been shown to ameliorate symptoms of brain dysfunction in both animals models and Parkinson's disease, although problems still remain. The newly introduced technique of ex vivo gene transfer could serve as an alternative approach, possible avoiding some of the draw-backs of the embryonal tissue used in neuronal grafting. We have investigated the feasibli
Manufacturing is an industry in which the effects of globalization are obvious. Manufacturing costs are a key factor in this respect and affect, for example, decisions about offshoring, i.e., moving production abroad. If Sweden and other Western countries are to maintain large manufacturing sectors, they must be competitive, making cost one of the most critical parameters. The work presented here
Stable isotopes of nitrogen (delta(15) N) and carbon (delta C-13) were measured for Atlantic salmon Salmo salar and their intestinal cestode, Eubothrium crassum, sharing the same diet. Atlantic salmon muscle tissues were enriched in N-15 and depleted in C-13 compared to their prey (sprat Sprattles sprattus sprattus) and their intestinal cestode. There was no significant difference in delta N-15 or
The objective of this study was to investigate the feasibility of the Aerodynamic Particle Sizer (APS) and the Electrical Low-Pressure Impactor (ELPI) to study mass weighted particle size distributions. Unimodal and bimodal liquid test aerosols were produced to a small chamber. Simultaneous measurements were performed with an APS 3320, an APS 3321, an ELPI and a Dekati Low-Pressure Impactor (DLPI)
There are considerable biomass resources in the European Union (EU) and mature conversion technologies to exploit the potentials of bioenergy. The challenge confronting the EU and member states is how to accelerate the implementation of bioenergy systems. This paper contributes to the identification, analysis, and discussion of barriers for bioenergy in the EU. Adopting an innovative methodology i
Multiangle light scattering (MALS) is a well-established technique used to determine the size of macromolecules and particles. In this study, different extrapolation procedures used in MALS were investigated with regard to accuracy and robustness in the obtained molar mass and rms radius. Three different mathematical transformations of the light scattering function referred to as the Debye, Zimm,
This paper presents the coupled cluster/molecular mechanics (CC/MM) and self-consistent field/molecular mechanics (SCF/MM) approaches for wavefunctions, energies and response properties. Two physically different theories are derived, the mean-field and the direct-field interaction approaches, together with expressions for the optimization condition of both variational and non-variational wavefunct
