Injuries to the upper gastrointestinal tract occurring over a 30-year period in a geographically well defined region were analyzed. The incidence was low in comparison with other abdominal injuries, but duodenal and pancreatic injuries were increasingly common in the study's last decade. The stomach injuries were mainly caused by penetrating trauma. The duodenal and pancreatic injuries most common

Local research units. this article argues, play a very important role for the scientific field they belong to, for example by mobilizing financial support, offering job opportunities, attracting talented recruits, and providing adequate training. Little is known, however, about such units, at least in the fields under study here, i.e., studies of innovation, entrepreneurship and related phenomena.

A new energy and angle resolved analyzer for photoelectron spectroscopy is described. This analyzer is based on combining an advanced focusing electron lens system with time-of-flight measurements. A position sensitive detector gives time and position for the electron events. From this information the kinetic energy and start direction are obtained through a transformation procedure, giving both a

Background: As more people reach older age, there is a growing interest in improving old person's health, activity, independence and social participation, thereby adding quality to the extended years. Preventive home visits (PHV) programs for old people have received much attention in recent decades. A large body of research shows mixed effects, and argues that a home visit is a complex social pro

Popular Abstract in Swedish I vår egen tid finns ett stort intresse för släktforskning och historia hos många. Men man tänker sällan på att även människor i gångna tider kunnat blicka tillbaka på sitt förflutna och fundera på sin egen plats i släktleden. Vad var de ville minnas och hur mindes de i en tid utan skriv- och läskunnighet? Det är frågor som ställs i avhandlingen och där svaren söks i deThis thesis examine how farm-dwellers in the Mälaren region during the late Iron Age and early Middle Ages created, transferred, and preserved memory by deliberately placing new houses and graves on the houses and graves of previous generations. Focus is on memory as a social phenomenon and culture-specific resource created by these deliberate practices. The culture-specific element is oral cultur

Rubidium concentrations in tissues of organisms (vascular plants, fungus, insect, bird, rodents) were closely related to soil chemical properties (K+ saturation as % cation exchange capacity, and pH) at repeated sampling of 30 beech forest sites in south Sweden. The Rb+ concentration of organisms, representing a variety of tropic levels, was a sensitive measure of the K+ status of acid soil ecosys

Popular Abstract in Swedish Interaktionen i fyra olika utvecklingssamtal från åldringsvård, industri och skola beskrivs i den här avhandlingen. Till grund ligger kritisk analys av samtalens situationella kontext, organisation och språkliga uttrycksformer. Resultaten jämförs också med hur samtalsdeltagarna själva bedömer interaktionen. Utvecklingsamtalen visar sig inte vara så ömsesidiga som de tiThis dissertation is an investigation into Swedish “utvecklingssamtal”, i.e. a kind of annual, re-curring staff development talk. The investigation consists of four empirical analyses. The first analysis concerns the situational context. The second analysis concerns the structure of the talks, the content and informal organisation. In the third analysis, I have worked quite closely to the theoreti

Absorption, reflection and emission polarization spectra of CdWO4 crystals have been studied in the region 3.5-30 eV in order to distinguish the excitonic and electron-hole processes in the vicinity of the band gap. The following parameters have been defined from the Urbach tail study at 6-300 K: E-0 = 5 eV, sigma(0) = 0.31, homega = 70 meV (565 cm(-1)). Excitonic processes have been shown to domi

Results from a Monte Carlo investigation are presented for the application of the dual photopeak window (DPW) scatter correction method to phantom geometries of varying shapes, sizes, and densities as well as to several collimators. A Monte Carlo program was used to simulate a Tc-99m point source at locations of 0.5 cm from the phantom surface, at the center, 0.5 cm from the bottom, and 4/5 the di

In this report we present an extension of the pooled analysis of the prognostic impact of urokinase-type plasminogen activator (uPA) and its inhibitor PAI-I in breast cancer patients. We analyzed a different endpoint, metastasis-free survival (MFS). We checked the consistency of the estimates for uPA and PAI-I for relapse-free survival (RFS) and MFS exploring possible sources of heterogeneity. Nod

Inspired by biomolecular motors, as well as by theoretical concepts for chemically driven nanomotors, there is significant interest in constructing artificial molecular motors. One driving force is the opportunity to create well-controlled model systems that are simple enough to be modeled in detail. A remaining challenge is the fact that such models need to take into account processes on many dif

We report on measurements of the light absorption efficiency of InSb nanowires. The absorbed 70 fs light pulse generates carriers, which equilibrate with the lattice via electron-phonon coupling. The increase in lattice temperature is manifested as a strain that can be measured with X-ray diffraction. The diffracted X-ray signal from the excited sample was measured using a streak camera. The amoun

Popular Abstract in Swedish Högt blodtryck (hypertoni) är en folksjukdom. Omkring 1,8 miljoner personer i Sverige, motsvarande 25 % av den vuxna befolkningen över 20 år, lider av hypertoni. I 90 % av fallen är orsaken okänd och klassificeras då som essentiell/primär hypertoni. Vid sekundär hypertoni finns det en eller flera bakomliggande orsaker till det höga blodtrycket, till exempel: förträngninArterial hypertension is a very common disorder. In most cases the cause is unknown and therefore classified as essential or primary hypertension. Primary aldosteronism (PA), characterized by an inappropriate aldosterone secretion, has traditionally been estimated to account for approximately 1 % of all hypertensive cases. By using the aldosterone to renin ratio (ARR) as a screening tool, the dete

In this work, we discuss the possibility of a new approach to measuring oxygen isotope ratios in fossil meteorite samples, specifically one based on nuclear reaction analysis (NRA). Variations of oxygen ratios within meteoritic chromite grains can help to determine the type of meteorite to which the grains originally belonged. In this work, we have evaluated the possibility to use the reaction O-1

OBJECTIVE:: To investigate the effects of physical exercise during work hours (PE) and reduced work hours (RWH) on direct and indirect costs associated with sickness absence (SA). METHODS:: Sickness absence and related costs at six workplaces, matched and randomized to three conditions (PE, RWH, and referents), were retrieved from company records and/or estimated using salary conversion methods or

Turbulent flow through 90 degrees pipe bends, for four different curvatures, has been investigated using large eddy simulations. In particular, the origin of the so-called swirl switching phenomenon, which is a large scale oscillation of the flow after the bend, has been studied for different bend curvature ratios. A classification of the phenomenon into a high and a low frequency switching, with

Recent studies have shown that activation of the complement and contact systems results in the generation of antibacterial peptides. Streptococcus pyogenes, a major bacterial pathogen in humans, exists in more than one hundred different serotypes due to sequence variation in the surface-associated M protein. Cases of invasive and life-threatening S. pyogenes infections are commonly associated with

As high resolution instruments are becoming standard in proteomics laboratories, label-free quantification using precursor measurements is becoming a viable option, and is consequently rapidly gaining popularity. Several software solutions have been presented for label-free analysis, but to our knowledge no conclusive studies regarding the sensitivity and reliability of each step of the analysis p

After their local extinction in 1954, White Storks (Ciconia ciconia) were reintroduced to Sweden in 1989. The founder Population for the reintroduced birds originated in North Africa, rather than from the closest breeding population in northeastern Europe (defined here as native). A number of wild storks have immigrated spontaneously, and a few others of native origin have been acquired for captiv
