The magnet lattice of the MAX IV storage rings
A successor of the present MAX facility is currently being studied. This proposed MAX IV facility will then have two new storage rings operated at 1.5 and 3 GeV respectively. The magnet lattices of the two storage rings are almost identical and the rings are placed coaxially, one on top of the other. A third ring, the MAX III ring, now under construction, should be transferred to the new facility.
A documented amphibian decline over 40 years: Possible causes and implications for species recovery
Amphibians are declining worldwide, but lack of long-term regional data makes identifying possible causes difficult, hindering conservation efforts. We evaluated whether habitat destruction, terrestrial habitat adjacent to ponds and the physico-chemical characteristics of ponds could explain the regional and local decline of the spadefoot toad (Pelobates fuscus) in Sweden. Analyses of aerial photo
A meta-analysis of four European genome screens (GIFT Consortium) shows evidence for a novel region on chromosome 17p11.2-q22 linked to type 2 diabetes.

Validation of Gastrointestinal Quality of Life Index in Swedish for Assessing the Impact of Gallstones on Health-Related Quality of Life
The aim of the present study was to validate a Swedish translation of the Gastrointestinal Quality of Life Index (GIQLI) questionnaire in patients with gallstone disease. Sensitivity to change, internal consistency, and test-retest stability were tested in 187 consecutive patients who underwent planned cholecystectomy. Construct validity was assessed by comparing the GIQLI score with the bodily pa
Effect of different cooking methods on the formation of mutagenic compounds in meat.
Hamburgers and chicken fillets were cooked in convection ovens, deep-fried or contact fried and analysed for mutagenic activity using the Ames test. For the three different convection ovens, the cooking parameters studied included the presence of steam, air velocity, air temperature and holding time. For deep-frying and contact frying, the cooking parameters included cooking temperature and cookin
A non-Newtonian model based on limiting shear stress and slip planes - parametric studies
Parametric studies and corresponding results are presented using a theological model based on the limiting shear stress and possible occurrence of slip planes. The model is applied to elastohydrodynamically lubricated line contacts with smooth surfaces and isothermal conditions. A few investigations are carried out where different parameters are varied. The first study investigates the influence o
Strategy-proof and nonbossy allocation of indivisible goods and money
Which strategy-proof nonbossy mechanisms exist in a model with a finite number of indivisible goods (houses, jobs, positions) and a perfectly divisible good (money)? The main finding is that only a finite number of distributions of the divisible good is consistent with strategy-proofness and nonbossiness. Under various additional assumptions - neutrality, individual rationality, object efficiency,
Duality in $H^infty$ Cone Optimization
Positive real cones in the space $H^infty$ appear naturally in many optimization problems of control theory and signal processing. Although such problems can be solved by finite-dimensional approximations (e.g., Ritz projection), all such approximations are conservative, providing one-sided bounds for the optimal value. In order to obtain both upper and lower bounds of the optimal value, a dual pr
How complete and correct was Linnaeus’ knowledge and classification of the Swedish flora?
The degree to which Carolus Linnaeus managed to describe the vascular plant species diversity of his native country, and the proportion of his taxonomic decisions concerning the rank and generic classification of these same species that are considered correct by present-day taxonomists, is analyzed by comparing the most recent checklist of the Swedish flora, excluding later immigrants, with the wo
High GATA-2 expression inhibits human hematopoietic stem and progenitor cell function by effects on cell cycle
Evidence suggests the transcription factor GATA-2 is a critical regulator of murine hematopoietic stem cells. Here, we explore the relation between GATA-2 and cell proliferation and show that inducing GATA-2 increases quiescence (G(0) residency) of murine and human hematopoietic cells. In human cord blood, quiescent fractions (CD34(+)CD38(-)Hoechst(lo)Pyronin Y-lo) express more GATA-2 than cycling
Prospective malignancy grading of invasive squamous carcinoma of the uterine cervix. Prognostic significance in a long-term follow-up.
A multifactorial grading score (MGS) for invasive squamous cell carcinoma of the uterine cervix has demonstrated its capacity to predict survival in a 5-10 year perspective and metastasis frequencies, and is a valuable tool for treatment schedules. In this study it was shown that the power of prognosis is valid even up to 20 years. In this material from 619 cervical carcinoma patients the MGS scor
Epidemiology of amputations and severe injuries of the hand
In a prospective population-based study, all open hand, wrist, and forearm injuries that were treated during a 10-year period, at hospitals and emergency wards in three Norwegian cities with 225,000 inhabitants, were registered. Injury severity was graded using the abbreviated injury scale (AIS). For moderate injuries (AIS 2) overall incidence (95% CI) was 59 (56-62), incidence among males 92 (86-
Increasing the benefits of eye-tracking devices in divided visual field studies of cerebral asymmetry
A wide range of methods has been proposed for ensuring central fixation in divided visual field studies of cerebral asymmetry. We present some of the problems associated with ensuring central fixation and argue that objectively monitoring fixation location with an eye-tracking device can provide the only accurate and, therefore, acceptable technique. However, the mere use of this equipment does no
The intensity threshold of colour vision in two species of parrot
We have used behavioural tests to determine the intensity thresholds of colour vision in Bourke's parrots (Neopsephotus bourkii) and budgerigars (Melopsittacus undulatus). We have also examined the relationship between these thresholds and the optical sensitivities of single photoreceptors using morphological methods. Bourke's parrots lose colour vision in brighter light (0.4 cd m(-2)) than budger
Neuropathological correlates to clinically defined dementia with Lewy bodies
OBJECTIVES: To analyse the neuropathological changes behind clinically defined dementia with Lewy bodies (clinDLB) compared with clinically diagnosed Alzheimer's disease (clinAD). METHODS: The prevalence of neuropathological findings in 48 clinDLB and 45 clinAD cases was compared. Sixteen clinDLB and 10 clinAD cases were reassessed with alpha-synuclein staining for Lewy bodies (LB). RESULTS: Alzhe
Scandinavian guidelines - "The massively bleeding patient"
Neck pain and dysphagia: MRI of retropharyngitis
OBJECTIVE: Acute neck pain developing over hours or a few days is often an alarming symptom that may be due to an inflammatory process or another process affecting the spine or the spinal canal, nerve roots, or peripheral nerves. MATERIALS AND METHODS: Four patients with acute onset of neck pain and dysphagia are presented. They were examined with MRI and CT, barium swallow, and plain radiography
An investigation of dynamic suface tension, critical micelle concentration, and aggregation number of three nonionic surfactants using NMR, time-resolved fluorescence quenching, and maximum bubble pressure tensiometry
Several physicochemical properties have been determined for N-dodecyllactobionamide (LABA), maltose 6'-O-dodecanoate (C-12-maltose ester), and tetra(ethylene oxide) dodecyl amide (TEDAd). The increase in the flexibility of the sugar headgroup, enabling more possible molecular conformations, reduces the minimum area/molecule at the liquid-vapor interface obtained at the critical micelle concentrati
