Lunds senmiddelalderlige mønt

Artikeln diskuterar den senmedeltida myntningen i Lund med anledning av en arkeologisk undersökning utförd av Kulturen i kv. Myntet, Lund. I kvarteret har det senmedeltida myntverket varit lokaliserat. I undersökningen påträffades rikliga mängder med deglar efter metallhantverk.

Normal visual fields as assessed by computerized static threshold perimetry in patients with untreated primary hypothyroidism

In this prospective study, 25 consecutive patients with untreated primary hypothyroidism were tested with a highly sensitive perimetric technique, since a high prevalence of visual field defects has been described in this condition. All patients had clinical hypothyroidism, a serum TSH value greater than 20 mU/l (reference range 0.4-4.0) and decreased/low normal serum total T4 concentration. Visua

Faster algorithms for finding lowest common ancestors in directed acyclic graphs

We present two new methods for finding a lowest common ancestor (LCA) for each pair of vertices of a directed acyclic graph (dag) on n vertices and m edges. The first method is surprisingly natural and solves the all-pairs LCA problem for the input dag on n vertices and m edges in time 0 (n m). The second method relies on a novel reduction of the all-pairs LCA problem to the problem of finding max

Increased presence of eosinophilic granulocytes expressing transforming growth factor-beta1 in collagenous colitis

BACKGROUND: Collagenous colitis is a disease characterized by chronic watery diarrhea, and on microscopic examination of colonic tissue, a typical thickening of the subepithelial collagen layer is seen. The etiology and pathophysiology behind this disease state are largely unknown. METHODS: We have used in situ hybridization and immunohistochemistry to study the expression of transforming growth f

Market Structure and Integration - Essays on Trade, Specialisation and Foreign Direct Investment

Popular Abstract in Swedish Avhandlingen studerar olika aspekter av internationell ekonomi knutna till utländska direktinvesteringar, produktionsmönster och handelsflöden. Dessa behandlas i ljuset av en globalt tilltagande internationalisering såväl som fördjupad ekonomisk integration på regional nivå. I kapitel två studeras effekten av utländska direktinvesteringar av multinationella företag på vThe study analyses various aspects of international economics related to foreign direct investment, trade and specialisation. These issues are considered in view of the increased internationalisation - through trade and foreign direct investment - in recent decades. Special interest is devoted to the effects of economic integration. Chapter two examines the importance of FDI and country capabiliti

Solid state quantum memory using complete absorption and re-emission of photons by tailored and externally controlled inhomogeneous absorption profiles

We present a scheme for storage and retrieval of the quantum state of a single-photon or a weak classical or non-classical optical wave-packet, in a solid-state medium. We describe how the spectral absorption profile of a material such as a rare-earth-ion-doped crystal can be manipulated to efficiently absorb and subsequently reemit a wave-packet, in a photon echo-like process. We discuss how the

Laser light scattering in turbid media part I: Experimental and simulated results for the spatial intensity distribution

We investigate the scattering and multiple scattering of a typical laser beam (lambda= 800 nm) in the intermediate scattering regime. The turbid media used in this work are homogeneous solutions of monodisperse polystyrene spheres in distilled water. The two-dimensional distribution of light intensity is recorded experimentally, and calculated via Monte Carlo simulation for both forward and side s

InP quantum dots in GaInP

InP quantum dots grown on GaInP by the Stranski-Krastanow technique are less well studied than InAs quantum dots grown on GaAs. We here give a review of the main experimental evidence for the InP dots being charged when grown in between n-type barriers.

Prevalence of asthma in young cross-country skiers in central Scandinavia: differences between Norway and Sweden

An increased prevalence of asthma in cross-country skiers has been reported previously. This study was conducted in order to evaluate the prevalence of asthma among young, elite cross-country skiers in Trondelag, Norway and Jamtland, Sweden. These two regions in central Scandinavia have different climates during the winter season, with a coastal type in Trondelag while Jamtland is characterized by

A critical appraisal of the use of umbilical artery Doppler ultrasound in high-risk pregnancies: use of meta-analyses in evidence-based obstetrics

Objectives To reanalyze randomized controlled trials on the use of umbilical artery Doppler velocimetry in high-risk pregnancies and determine which high-risk pregnancies benefit from the use of Doppler velocimetry, Methods Searching Medline, the Cochrane Library and Embase we found 13 randomized controlled trials on the use of Doppler velocimetry in high-risk pregnancies. Of these, six included p

Bioinformatics in proteomics

Several genome sequencing projects have recently been completed and the majority of human coding regions have been sequenced. In the next step many of the further studies will concentrate on proteins. Proteomics methods are essential for studying protein expression. activity, regulation and modifications. Bioinformatics is an integral part of proteomics research. The recent developments and applic

Inter- and intramolecular potential for the N-formylglycinamide-water system. A comparison between theoretical modeling and empirical force fields

An intramolecular NEMO potential is presented for the N-formylglycinamide molecule together with an intermolecular potential for the N-formylglycinamide-water system. The intramolecular N-formylglycinamide potential can be used as a building block for the backbone of polypeptides and proteins. Two intramolecular minima have been obtained. One, denoted as C5, is stabilized by a hydrogen bonded five

The 39-item Parkinson's disease questionnaire (PDQ-39) revisited: implications for evidence-based medicine.

Background: The 39 item Parkinson's disease questionnaire (PDQ-39) is the most widely used patient reported rating scale in Parkinson's disease. However, several fundamental measurement assumptions necessary for confident use and interpretation of the eight PDQ-39 scales have not been fully addressed. Methods: Postal survey PDQ-39 data from 202 people with Parkinson's disease (54% men; mean age 70

Kin competition and the evolution of dispersal in an individual-based model

The evolution of dispersal was investigated in an adaptive individual-based metapopulation model, which allowed for demographic and environmental stochasticity. The individual dispersal behaviour was determined by a one-locus genotype subjected to simple inheritance and mutation. Dispersal behaviour could therefore evolve through the genotype–phenotype mapping and the selection regimes stemming fr

Expression and biological role of laminin-1.

Of the approximately 15 laminin trimers described in mammals, laminin-1 expression seems to be largely limited to epithelial basement membranes. It appears early during epithelial morphogenesis in most tissues of the embryo, and remains present as a major epithelial laminin in some adult tissues. Previous organ culture studies with embryonic tissues have suggested that laminin-1 is important for e

Augmentation mammaplasty--psychiatric and psychosocial characteristics and outcome in a group of Swedish women

Thirty-eight women undergoing augmentation mammaplasty, consecutively operated on at the Department of Plastic and Reconstructive Surgery, Malmo, Sweden, were studied preoperatively regarding medical history, personality, psychosocial and psychiatric characteristics. Thirty-six of these patients were interviewed one year postoperatively. Thirty-three age-matched women operated on with minor surgic
