Background: The Child and Adolescent Twin Study in Sweden (CATSS) is an on-going, large population-based longitudinal twin study. We aimed (1) to investigate the reliability of two different versions (125-items and 238-items) of Cloninger's Temperament and Character Inventory (TCI) used in the CATSS and the validity of extracting the short version from the long version, (2) to compare these person

Popular Abstract in Swedish Diarré är ett vanligt symptom i befolkningen och det finns många differentialdiagnoser bakom orsaken till detta. En är inflammatorisk tarmsjukdom, något som har ökat kraftigt de senaste decennierna. Idag beräknar man att ca 1% av befolkningen har någon form av inflammatorisk tarmsjukdom och den klassas därför som en folksjukdom i Sverige. De inflammatoriska tarmsjukdomCollagenous colitis (CC) affects middle-aged women and results in chronic watery non-bloody diarrhoea. The incidence of CC has increased but has never been determined in southern Sweden. During the period 2001-2010 the mean annual incidence was stable; 5.4/105 (median age 71 years). The female: male ratio was 2.8:1, lower than in previous reports. The association between smoking and classic IBD is

The aim of this study was to find models for turbulent fragmenting forces in the high-pressure homogeniser from data available in Computational Fluid Dynamics (CFD) simulations with Reynolds Averaged Navier Stokes (RANS) turbulence models. In addition to the more common RANS k-epsilon turbulence models, a Multi-scale k-epsilon model was tested since experimental investigations of the geometry impl

The rapidly growing collection of diverse genome-scale data from multiple tumor types sheds light on various aspects of the underlying tumor biology. With the objective to identify genes of importance for breast tumorigenesis in men and to enable comparisons with genes important for breast cancer development in women, we applied the computational framework COpy Number and EXpression In Cancer (CON

The Price of Democracy and the Value of Literature : Books, Politics, and the Literary Market with Respect to the 2002 Reduction in VAT on Books in Sweden In 2002 the VAT (value added tax) on books in Sweden was reduced from 25% to 6 %. The reduction was effected in response to a cultural policy, whose aim was to ”improve the conditions for literature and reading” and ”stimulate a diversifed out

MRI diffusion tensor imaging (DTI) studies of white matter integrity in behavioral variant frontotemporal dementia have consistently shown involvement of frontal and temporal white matter, corresponding to regional loss of cortical volume. Volumetric imaging has a suboptimal sensitivity as a diagnostic tool and thus we wanted to explore if DTI is a better method to discriminate patients and contro

Popular Abstract in Swedish Personlighetspsykologer har i mer än ett århundrade försökt att identifiera och beskriva observerbara skillnader mellan individer. Bland dessa indiduella skillnader har intelligens och personlighet fått stor uppmärksamhet inom skolvärlden, liksom elevers förhållningssätt till sitt lärande. Kunskapen om vilka faktorer som påverkar studieresultat har viktiga praktiska konThe aim of the present doctoral thesis was to examine to what extent personality traits and approaches to learning contribute to academic performance in upper secondary school (high school), after controlling for the well-known fact that general intelligence accounts for a large part of the variance. The general proposition of the thesis is that personality traits are stable dispositons and theref

A numerical model was developed of beach morphological evolution in the vicinity of coastal structures. The model includes five sub-models for random wave transformation, surface roller development, nearshore wave-induced currents, sediment transport, and morphological evolution. The model was validated using high-quality data sets obtained during experiments with a T-head groin and a detached bre

A characteristic feature of non-muscle-invasive bladder cancer (NMIBC) is the high risk of recurrent disease after primary treatment. Although only a minority of cases eventually progress to a life-threatening muscle-invasive tumour, it is necessary to conduct long-term follow-up with repeated cystoscopies. In addition to the negative mental and physical impact that this has on the patient, the ex

Aim and objectives. This article explores relatives' experiences of receiving soft tissue massage as a support supplement while caring for a dying family member at home. Background. In palliative home care, relatives play an important role as carers to seriously ill and dying family members. To improve their quality of life, different support strategies are of importance. Complementary methods, su

Pressurized Hot Water Extraction (PHWE) is a quick, efficient and environmentally friendly technique for extractions. However. when using PHWE to extract thermally unstable analytes, extraction and degradation effects occur at the same time, and thereby compete. At first, the extraction effect dominates, but degradation effects soon take over. In this paper, extraction and degradation rates of ant

The surface structure of Pd(100) during CO oxidation was measured using a combination of a flow reactor and in situ surface X-ray diffraction coupled to a large-area 2-dimensional detector. The surface structure was measured for P-O2/P-CO ratios between 0.6 and 10 at a fixed total gas pressure of 200 mbar and a fixed CO pressure of 10 +/- 1 mbar. In conjunction with the surface structure the react

Ankylosing Spondylitis (AS) is a chronic, potentially disabling, inflammatory disease that poses a longstanding burden on the patient and the society. The epidemiology of AS in Sweden has not been extensively studied previously. Radiographic and self-perceived health information from 1,005 men aged 69-81 years, showed a prevalence of moderate to severe radiographic sacroiliitis of 1.4% (95% Confid

Weld residual stress (RS) measurements are often undertaken on test-pieces which have been Cut Out from large components, yet it remains unclear to what extent the RSs in test-pieces are representative of those present in the original component. Similarly weld mechanical performance tests are frequently undertaken on cross-weld test-pieces without a proper understanding of the level or influence o

The effect of a supercritical carbon dioxide (scCO(2)) treatment on the free volume of poly[1-(trimethylsilyl)-1-propyne] (PTMSP) and PTMSP-silica nanohybrid membranes was investigated with positron annihilation lifetime spectroscopy (PALS) and correlated with their performance in pervaporation. Treatment of dense unfilled PTMSP and silica filled PTMSP (2.5, 10 and 20 wt.% silica) membranes with s

This Letter presents the results of a search for a heavy particle decaying into an e(+/-)mu(+/-), e(+/-)tau(+/-), or mu(+/-)tau(+/-) final state in pp collisions at root s = 7 TeV. The data were recorded with the ATLAS detector at the LHC during 2011 and correspond to an integrated luminosity of 4.6 fb(-1). No significant excess above the Standard Model expectation is observed, and exclusions at 9

In the robotic manipulation context, end-effector contact forces may be difficult to measure mainly due to the tool dynamic interferences Such as the inertial forces. In this paper, a whole methodology is proposed to estimate these forces. The new approach is based oil a sensor fusion technique that integrates the information of a wrist force sensor. of a 3D accelerometer placed at the robot tool

Objective. The association between smoking and idiopathic inflammatory bowel disease is well known; smoking seems to have a diverse effect. Crohn's disease is associated with smoking, while ulcerative colitis is associated with non-smoking. Data on smoking in microscopic colitis of the collagenous type (CC) are lacking. The aim of this investigation was to study smoking habits in CC and to observe

Systemic lupus erythematosus (SLE) is an autoimmune rheumatic disorder characterized by inflammation in several organ systems. SLE patients have an impaired ability to clear dying cells which leads to the exposure of several nuclear antigens which might break self tolerance. Autoantibodies directed against the nuclear antigens will form large immune complexes (ICs) which are central in the immunop

Twelve fossil species of Proteaceous pollen, predominantly attributable to Proteacidites and Beaupreaidites, were recovered from the Maastrichtian-Paleocene sedimentary succession of the Garden Cove Formation on Campbell Island, the southernmost landmass of the Zealandia continent. Among these are two new species, Proteacidites campbellensis and Proteacidites hortisinus. The high diversity of Prot
