Capture into mean motion resonance (MMR) is an important dynamical mechanism because it shapes the final architecture of a planetary system. We simulate systems of two or three planets undergoing migration with varied initial parameters such as planetary mass and disk surface density and analyse the resulting resonant chains. In contrast to previous studies, our results show that the disk properti

Purpose of the studyIn this paper, we discuss the unexploited possibilities of user-orientation to promote sustainable governance and management of value co-creation in innovation projects within welfare service ecosystem. The paper’s theoretical framework takes the outset in public service logic (PSL) and its user-oriented perspective. As such, we test the thesis that service-innovation seriously

The need for information about climate change is great. This information is usually based on climate model data, which often have systematic biases. Furthermore, climate information is based on ensembles of climate models, which raises the question about how such ensembles are affected by the choice of models and emission scenarios. Here, we aim to describe climate change in Sweden and neighbourin

Lifetimes of photoexcited charge transfer (CT) states in transition metal chromophores are influenced by low-lying ligand field (LF) excited states, especially for 3d metal complexes. To manipulate interactions between LF and CT states, it is important to be able to control LF excited state energies using tunable synthetic variables. In this report, we use Fe 2p3d L3-edge resonant inelastic X-ray

The growing vulnerability of cities to extreme heat underscores the urgency of effective urban adaptation policies. Despite the progress in developing urban climate policies and strategies, there remains a significant disparity between intended goals and actual outcomes. This could entrench social and climate vulnerabilities that are costly and challenging to address, potentially resulting in rein

Popular Abstract in Swedish Denna avhandling analyserar frågor som berör tillfälliga jobb på den svenska arbetsmarknaden under perioden 1990-1999. Ett viktigt bidrag i avhandlingen är att den stora gruppen tillfälliga jobb delas upp i mindre undergrupper för att ta i beaktande den heterogenitet som finns mellan olika former av tillfälliga jobb. En röd tråd som löper genom hela avhandlingen är fokuThis thesis analyses different aspects of temporary jobs in the Swedish labour market during 1991-1999. Throughout the thesis we put special focus on differences between the genders, and differences between native-born and foreign-born workers. In chapter 1, An Introduction to Temporary Jobs in Sweden, we describe the evolution of different types of temporary jobs in Sweden during the 1990s, we re

Popular Abstract in Swedish Cykeln som transportmedel har många fördelar för individ och samhälle. Det är ett mycket energisnålt transportmedel, det förorenar inte, bullrar inte, tar liten plats och ger dem som cyklar välbefinnande och motion. Om fler cyklade istället för att åka bil skulle detta medföra trevligare stadsmiljöer. Ökad cykling hade också kunnat bidra till en ökad folkhälsa. För närThis work presents an evaluation of bicycle lane effects on cyclist safety and the ability of bicycles to compete with car traffic. Thirteen Swedish urban streets were studied before and after bicycle lanes were introduced. Data was collected using video recordings, speed studies, road side questionnaires/interviews with cyclists/car drivers, conflict studies and accident analysis. Results showed

Cellulose, a polysaccharide consisting of beta-1,4-linked glucose, is the major component of plant cell walls and consequently one of the most abundant biopolymers on earth. Carbohydrate polymers such as cellulose are molecules with vast diversity in structure and function, and a multiplicity of hydrolases operating in concert are required for depolymerisation. The bacterium Rhodothermus marinus,

We consider a distribution system consisting of a central warehouse and a group of retailers facing independent stochastic demand. The retailers replenish from the warehouse, and the warehouse from an outside supplier with ample supply. Time is continuous. Most previous studies on inventory control policies for this system have considered stock-based batch-ordering policies. We develop a time-base

Couplings of microscopic stochastic models to deterministic macroscopic ordinary and partial differential equations are commonplace in numerous applications such as catalysis, deposition processes, polymeric flows, biological networks and parametrizations of tropical and open ocean convection. In this paper we continue our study of the class of prototype hybrid systems presented in [8]. These mode

The cGMP-dependent protein kinase (PKG) is the main mediator of nitric oxide-induced relaxation of smooth muscle. Although this pathway is well established, the cellular action of PKG, nitric oxide, and cGMP is complex and not fully understood. A cross-talk between the cGMP-PKG and other pathways (e.g. cAMP-protein kinase A) seems to exist. We have explored cGMP- and cAMP-dependent relaxation of s

The interaction and hierarchy of celestial and magnetic compass cues used by migratory songbirds for orientation has long been the topic of an intense debate. We have previously shown that migratory Savannah sparrows, Passerculus sandwichensis, use polarized light cues near the horizon at sunrise and sunset to recalibrate their magnetic compass. Birds exposed to a +/-90 deg. shifted artificial pol

Recombinant adeno-associated viral (rAAV) vector-induced neuropeptide Y (NPY) overexpression in the hippocampus exerts powerful antiepileptic and antiepileptogenic effects in rats. Such gene therapy approach could be a valuable alternative for developing new antiepileptic treatment strategies. Future clinical progress, however, requires more detailed evaluation of possible side effects of this tre

This study examines fuel use and metabolism in a group of long-distance migrating birds, red knots Calidris canutus (Scolopacidae), flying under controlled conditions in a wind tunnel for up to 10 h. Data are compared with values for resting birds fasting for the same time. Plasma levels of free fatty acids, glycerol and uric acid were elevated during flight, irrespective of flight duration (1-10h

Community mobility, defined as "moving [ones] self in the community and using public or private transportation", has a unique ability to promote older peoples' wellbeing by enabling independence and access to activity arenas for interaction with others. Early predictors of decreased community mobility among older men and women are useful in developing health promoting strategies. However, long-ter

The purpose of this study was to explore neuroretinal transplantation in a large animal model of severe retinitis pigmentosa and to establish graft development, long-term survival, graft-host integration, and effects on the host retina. Methods Rhodopsin transgenic pigs, aged 6 months, received in one eye a fetal full-thickness neuroretinal sheet in the subretinal space by means of vitrectomy and

Theoretical work on intraguild predation suggests that if a top predator and an intermediate predator share prey, the system will be stable only if the intermediate predator is better at exploiting the prey, and the top predator gains significantly from consuming the intermediate predator. In mammalian carnivore systems, however, there are examples of top predator species that attack intermediate

The purpose of this work was to study if enriched housing conditions and fetal neocortical transplantation could enhance the functional outcome after focal brain ischemia in adult rats. The right middle cerebral artery (MCA) was ligated in 34 inbred, spontaneously hypertensive male rats, which were then randomly divided into three groups. Groups A and B were transferred to an enriched environment,
