A novel algorithm for detection of saccades and postsaccadic oscillations in the presence of smooth pursuit movements is proposed. The method combines saccade detection in the acceleration domain with specialized on- and offset criteria for saccades and postsaccadic oscillations. The performance of the algorithm is evaluated by comparing the detection results to those of an existing velocity-based
Background: Meat intake may be related to weight gain because of its high energy and fat content. Some observational studies have shown that meat consumption is positively associated with weight gain, but intervention studies have shown mixed results. Objective: Our objective was to assess the association between consumption of total meat, red meat, poultry, and processed meat and weight gain afte
The EU strategy for rural development 2014-2020 proposes a focus on tourism as a solution to bring economic, environmental and social aspects of sustainable development together. Using the case of fishing tourism in Sweden, we discuss the marketization of sustainable development on a destination market. We focus on the discursive and practical tension between ambitions for development and maintena
For construction in rock a thorough pre-investigation is important in order to avoid unforeseen conditions which may delay the work. It is crucial to remember the results from this investigation in the further work, and use the experience from the construction to update the geological prognosis and reduce the uncertainties. Different geophysical methods have proved valuable tools in such investiga
We measured H2O and CO2 fluxes at a boreal forest floor using eddy covariance (EC) and chamber methods. Maximum evapotranspiration measured with EC ranged from 1.5 to 2.0 mmol m(-2) s(-1) while chamber estimates depended substantially on the location and the vegetation inside the chamber. The daytime net CO2 exchange measured with EC (0-2 mu mol m(-2) s(-1)) was of the same order as measured with
Using constant-effort catch data, causes of annual variation in the timing of migration of Curlew Sandpipers (Calidris ferruginea) migrating through Ottenby, Sweden, as well as the trend in timing of migration from 1946-2005, was investigated. Variation in the timing of autumn migration of adult and juvenile Curlew Sandpipers was influenced by breeding success connected to predation pressure on th
We have synthesized hematite cube-shaped nanoparticles using different synthesis paths to examine the effect of the intermediate product akaganeite (beta-FeOOH) on the size and shape of the final hematite particles. Akaganeite spindles and hematite nanocubes are prepared using forced hydrolysis of iron chloride (FeCI3) salt. We use a combination of transmission electron microscopy (TEM), high reso
The aim of this thesis was to explore the impact of meniscal injury and meniscectomy on joint and muscle function, physical activity and perceived health in middle-age subjects and to evaluate the effect of a functional exercise program. Male and female post meniscectomy patients participated in Studies I-IV (n=45 in Studies I-III, n=99 in Study IV) and Study IV also included 94 controls. Outcome
Event-by-event fluctuations of the mean transverse momentum of charged particles produced in pp collisions at root s = 0.9, 2.76 and 7 TeV, and Pb-Pb collisions at root S-NN = 2.76 TeV are studied as a function of the charged-particle multiplicity using the ALICE detector at the LHC. Dynamical fluctuations indicative of correlated particle emission are observed in all systems. The results in pp co
Aims. We attempt to derive accurate transition probabilities for astrophysically interesting spectral lines of Nb II and Nb III and determine the niobium abundance in the Sun and metal-poor stars rich in neutron-capture elements. Methods. We used the time-resolved laser-induced fluorescence technique to measure radiative lifetimes in Nb II. Branching fractions were measured from spectra recorded u

Scandinavian Journal of Psychology.Relations between results of the Stress Strategy Test (SST), a computerized test the first author developed partly involving the Stroop effect, and of an interview and an intelligence test used by the Swedish armed forces as
This thesis assesses aspects of the wetland development, permafrost dynamics and associated changes in carbon and nutrient cycling of the Stordalen Mire in northern Sweden. Various ecological and biogeochemical analyses of one peat and two lake sediment sequences were conducted, including analyses of organic matter and carbonate content, mosses, diatoms, testate amoebae, pigments, carbon and nitro
It is important to understand the role that different predators can have to be able to predict how changes in the predator assemblage may affect the prey community and ecosystem attributes. We tested the effects of different stream predators on macroinvertebrates and ecosystem attributes, in terms of benthic algal biomass and accumulation of detritus, in artificial stream channels. Predator richne
The age specific patterns of reproduction and mortality dictated by the life history of an organism apply to potential invaders as well as resident species of an area, but whether certain life history traits are more invasive than others is an unresolved issue. We analyze a two-population system of an invading and a resident species and test the effects of age on the probability to invade when the
The solids-flux theory has been used for half a century as a tool for estimating concentration and fluxes in the design and operation of secondary settling tanks during stationary conditions. The flux theory means that the conservation of mass is used in one dimension together with the batch-settling flux function according to the Kynch assumption. The flux theory results correspond to stationary
Background: Fragility fractures are a major health problem world wide and the numbers are growing due to ageing populations. Early identification of individuals at risk for osteoporosis and fracture, enabling preventive measures and treatment is essential. Bone strength is partly dependent on lifestyle but genetic factors account for approximately 70-80%. Parathyroid hormone (PTH) is the key regul
Popular Abstract in Swedish Grundvatten, det vatten som förekommer i hålrum i underjorden, är en av våra allra viktigaste naturresurser. Grundvattnet utgör den absolut största andelen för oss tillgängligt färskvatten och används för att producera mat och som processvatten inom olika industrier. Ungefär hälften av jordens dricksvattenförsörjning baseras på grundvattenuttag och ekosystem världen övePesticides are known to occur in groundwater worldwide. However, long-term pollution concerns and cause-effect relationships for specific regions remain limited. This thesis explores the occurrence of pesticides in south-Swedish groundwater, with the aims of providing a better knowledge basis for assessment and management of present-day and future pollution risks. The investigations are restricted
Popular Abstract in Swedish Tumörer i ben och mjukdelar är vanliga men utgör endast 1 % av alla maligna neoplasier. De elakartade tumörerna är ofta utmanande att diagnostisera pga deras relativt likartade morfologi samt att de är ovanliga. Således är all tilläggsinformation värdefull och genetiska analysmetoder kan bidra med information som är användbar och i vissa fall tom avgörande för diagnostiTumors of bone and soft tissue are common but only constitute 1 % of all malignant tumors. The malignant tumors are often difficult to diagnose due to their rarity and morphological resemblance between subtypes. This makes the diagnostic process challenging. Thus, there is a need for ancillary techniques, such as genetic analyses, not only for diagnostic purposes, but also for obtaining informatio
Ship-generated waves were investigated in the Gota alv river, which is a major waterway on the Swedish west coast between the sea and Lake Vanern. Ships with a typical size of 85x15x5 m (lengthxwidthxdraft) travel at speeds between 5 and 10 knots, generating waves that cause sediment transport and erosion along the river bed and banks. Field measurements of the wave properties and turbidity were c
