The recent decline in the Baltic cod Gadus morhua L. has been accompanied by an increase in population variability. Small population size, poor recruitment, and high population variability may be factors contributing to their imminent (commercial) extinction. Here we show that variable harvest rate, rather than variable recruitment, is the plausible cause of the increased variance in Baltic cod st

Purpose. The purpose was to evaluate the health-related quality of life (HRQL) of patients with pharyngeal carcinoma at diagnosis and after 1 and 5 years in relation to tumor location and treatment modality in a prospective multi-center study. Methods. Eighty-nine patients with pharyngeal carcinoma (mean age, 60.0 years; 76% men) were evaluated using the European Organization for Research and Trea

Leaf area index (LAI) of boreal ecosystems were estimated with optical instruments at the Laxemar and the Forsmark investigation areas in Sweden. The aim was to study the relationship between LAI and the normalized difference vegetation index (NDVI) from Landsat-5 and SPOT and evaluate the applicability of the MODIS (Moderate Resolution Imaging Spectroradiometer) LAI product for small boreal regio

At the University Hospital of Malmo, Sweden, standardized trauma charts were used for registration of all jaw fractures from 1972 to 1976. During the year 2005 the aim was to interview all patients treated non-surgically for unilateral mandibular condylar fractures during this period. In total, 49 patients with unilateral condylar fractures were treated non-surgically in 1972-1976. Of these, 23 pa

Bone disease is an important feature of multiple myeloma, and hypercalcaemia is a frequent complication of this disease. We examined the association between serum calcium and quality of life (QOL) scores of 686 multiple myeloma patients at the time of diagnosis. Data from two Nordic studies using the EORTC QLQ-C30 questionnaire were analysed by means of linear regression analysis and a curve fitti

Phobic postural vertigo patients might rely more on proprioceptive than visual cues to regulate stance. We tested 14 phobic postural vertigo patients and 24 healthy subjects with posturography during quiet stance and periods of vibratory proprioceptive calf muscle stimulation, both with eyes open and closed. During quiet stance phobic postural vertigo patients showed higher torque variance than he

This article presents data from an on-going project comparing L1 and L2 acquisition of Swedish syntax. Within the L1 group, normal as well as specifically language impaired (SLI) children are included; the L2 group consists of pre-school immigrant children. The analyses of the data are made within a second language acquisition perspective with a focus on word order. One basic issue within second l

[Context and motivation] In market-driven software development it is crucial, but challenging, to find the right balance among competing quality requirements (QR). [Problem] In order to identify the unique challenges associated with the selection, trade-off, and management of quality requirements an interview study is performed. [Results] This paper describes how QR are handled in practice. Data i

Time-resolved spectroscopy is a powerful technique permitting the separation of the scattering properties from the chemical absorption properties of a sample. The reduced scattering coefficient and the absorption coefficient are usually obtained by fitting diffusion or Monte Carlo models to the measured data using numerical optimization techniques. However, these methods do not take the spectral d

P>Studies have shown that familial risk contributes to aetiology of lymphomas. Using large population registries from Sweden, we evaluated risk of lymphoma subtypes among first-degree relatives of 2668 follicular lymphoma (FL) patients, 2517 diffuse large B-cell lymphoma (DLBCL) patients, and 6963 Hodgkin lymphoma (HL) patients compared to first-degree relatives of controls. Relatives were at the

Background: The importance of early life conditions and current conditions for mortality in later life was assessed using historical data from four rural parishes in southern Sweden. Both demographic and economic data are valid. Methods: Longitudinal demographic and socioeconomic data for individuals and household socioeconomic data from parish registers were combined with local area data on food

If u is a sufficiently smooth maximal plurisubharmonic function such that the complex Hessian of u has constant rank, it is known that there exists a foliation by complex manifolds, such that u is harmonic along the leaves of the foliation. In this paper, we show a partial analogue of this result for maximal plurisubharmonic functions that are merely continuous, without the assumption on the compl

In this prospective study, mortality, rehabilitation, and new amputations on the same or on the contralateral leg were studied in 189 patients with diabetes who had achieved healing of an index amputation. Ninety-three patients had achieved healing after an index minor (below the ankle) and 96 after an index major (above the ankle) amputation, precipitated by a foot ulcer. The healing time was 29

Shikimic acid, which is produced in the aromatic amino acid pathway in plants and microorganisms, is an industrially interesting chiral starting material for the synthesis of many chemical substances, e.g. the influenza medicine Tamiflu (R). When produced by genetically modified Escherichia coli it has previously been found that carbon-rich conditions (e.g. phosphate-limitation) favors production

BACKGROUND: Representing is about theories and theory formation. Philosophy of science has a long-standing interest in representing. At least since Ian Hacking's modern classic Representing and Intervening (1983) analytical philosophers have struggled to combine that interest with a study of the roles of intervention studies. With few exceptions this focus of philosophy of science has been on phys

We investigate the possibility to use coated metallic nanoparticles for single-molecule surface-enhanced spectroscopy by extending the Mie theory. The aggregates of metallodielectric spheres of Au and Ag show a strong local intensity enhancement in the cavity between particles, which can result in up to a 10(14)-fold increase for surface-enhanced Raman scattering. We also examine the thickness of

The European procedural guidelines for radionuclide imaging of myocardial perfusion and viability are presented in 13 sections covering patient information, radiopharmaceuticals, injected activities and dosimetry, stress tests, imaging protocols and acquisition, quality control and reconstruction methods, gated studies and attenuation-scatter compensation, data analysis, reports and image display,
