In the search for renewable vehicle fuels several different gasoline additives have been discussed and reviewed. Today bioethanol is the most commonly used option, but isobutanol is being proposed as a better alternative by many stakeholders, due to its superior fuel characteristics, e.g. energy density, oxygen content and vapor pressure. The research project “Glycerol-based isobutanol” has invest
Synthesis of case studies is different from synthesis of purely quantitative studies, for example, in that sampling and analysis in primary studies have been carried out differently, and that primary results are of a different nature. The objective of this research is to identify what challenges should be considered when choosing and using a method for synthesis of case studies. We collected exper
In the last few years, many vehicle manufacturers have introduced advance driver support in some of their automobiles. One of those new features is adaptive cruise control (ACC), which extends the conventional cruise control system to control of relative speed and distance to other vehicles. In order to design an ACC controller, it is suitable to have a model of drivers' behavior. Our approach to
If you want to become “teacher of the year“ - how do you do? The easy answer is to get yourself a group of “students of the year“! But, if you don't have that – how do you help your average students to become “students of the year“? In order to do that we must be active and take pedagogical leadership. In this roundtable we want to discuss questions like: • How can we stimulate the students’ inte
Popular Abstract in Swedish Den globala uppvärmningen av vår jord påverkar inte bara lufttemperaturen, utan även haven blir varmare. Dessutom förespås en ökning i nederbörd vilket kommer att göra havens ytvatten mindre salta. Temperaturförändringen och den ökade nederbörden kan leda till att skiktningen, den s.k. vertikala stratifieringen, som finns naturligt i haven blir skarpare och starkare. StIncreasing precipitation and surface water temperature due to global change may strengthen stratification in coastal regions, which could influence the behavior of dinoflagellate diel vertical migration (DVM). DVM is a behavioral mechanism by which dinoflagellates can access photosynthetically active radiation near the surface, and nutrients at depth. During this process, cells may need to cross b
It is often assumed that a main function of gestures is to compensate for expressive difficulties. This predicts that gestures should mainly occur with disfluent speech. However, surprisingly little is known about the relationship between gestures and fluent vs. disfluent speech. This study investigates the putative ompensatory role of gesture by examining competent speakers’ and language learners
This paper investigates the treatment of antonymy in Collins COBUILD Advanced Learner’s English Dictionary (2003) in order to find out what kinds of headwords are provided with antonyms as part of their definitions and also discusses the principles for antonym inclusion in the entries. CCALED includes canonical antonyms such as good/bad and dead/alive, as well as more contextually restricted pairi
Despite the popularity of the social investment approach, there remain ambiguities regarding how to design an effective social investment policy. We review evaluations of conditional cash transfers (CCTs) in Latin America in order to draw out lessons for how to improve the effectiveness of social investment. CCTs share many of the objectives of the social investment approach and are targeted at po
We used a proboscis extension reflex (PER) to study the olfactory discrimination capability in the moth Spodoptera littoralis. Already after a single experience, moths were capable to discriminate a rewarded from an unrewarded odor. In the first experiment, when rewarded and unrewarded odors were substituted for each other, moths were able to undergo reversal conditioning already after two experie
Popular Abstract in Swedish Formålet var at undersøge samspillet mellem pårørende til svækkede ældre patienter og sygeplejepersonalet i akutte hospitalsafdelinger, samt at udvikle og teste et instrument til at undersøge, udfra pårørendes perspektiv, samspillets dimensioner i denne kontekst og associationen mellem samspil og tilfredshed med patientforløbet. Den underliggende antagelse for studiet vThe aim was to investigate collaboration between relatives of frail elderly patients and nurses in acute hospital wards, and to develop and test an instrument to investigate, from the relatives? perspective, dimensions of collaboration in this context and the association between collaboration and satisfaction with the hospital care trajectory. The underpinning assumption for the study was that rel
Providing "always-on" Internet connectivity is crucial for mobile networks in automobiles and personal area networks. The Network Mobility (NEMO) protocol provides such a support involving a bi-directional tunnel between a gateway for the mobile network and a Home Agent. However, the routing path between them is hardly optimal. In this paper, we investigate the use of ad-hoc routing protocols for
Soils contain highly diverse communities of microorganisms and invertebrates. The trophic interactions between these species are largely unknown. Collembolans form an abundant part of the invertebrate community in soils. A prevailing view is that soil collembolans are generalist feeders on fungi, lichens, fragmented litter and bacteria. However, in laboratory food choice experiments, it has been s
This paper explores the concept of organizations as complex human activity systems, through the perspectives of alternative systemic models. The impact of alternative models on perception of individual and organizational emergence is highlighted. Using information systems development as an example of management activity, individual and collective sense-making and learning processes are discussed.
The purpose of safety systems is to reduce dangers to human life or environment to acceptable levels. In order to aid companies in this when developing safety systems for functional safety of machinery, the standard IEC 62061 has recently been released. The standard proposes an outlined design method to follow requirements specification. However, companies that use the standard have to implement a
The influence of added colloidal particles on the phase stability of polymer solutions is investigated theoretically. The polymer has an affinity to the particle surface. A mean-field lattice theory based on the Flory-Huggins theory is used to calculate the phase behavior in solutions containing a single polymer component and particles. The particles are described in two different ways. The first

Given electronic wave functions generated by the grasp2K relativistic atomic structure package, this program calculates diagonal magnetic dipole A(J) and electric quadrupole B-J hyperfine interaction constants and Lande g(J) factors. In addition the program computes diagonal and off-diagonal reduced hyperfine and Zeeman matrix elements and constructs the total interaction matrix for an atom in an
This thesis is about the patient and the professionals' experiences of participation and recovery in forensic psychiatric care. The purpose of the study was to investigate patients' and professionals' experiences of participation and what is considered to contribute to recovery from severe psychiatric illness. The study is based on a qualitative method and the empirical material consis
This thesis presents the results of an investigation into BIM standardisation needs and procedural supporting mechanisms that may enable design, construction and operating (DCO) organisations to advance their deployment of Building Information Modelling (BIM) technology, and improve construction project outcomes. To achieve sustainable development requires effective information management. Buildi
