Sn-seeded GaAs nanowires grown by MOVPE

It has previously been reported that in situ formed Sn nanoparticles can successfully initiate GaAs nanowire growth with a self-assembled radial p–n junction composed of a Sn-doped n-type core and a C-doped p-type shell. In this paper, we investigate the effect of fundamental growth parameters on the morphology and crystal structure of Sn-seeded GaAs nanowires. We show that growth can be achieved

Lika ideal, skilda uttryck : cistercienserna och premonstratenserna i östra Danmark

Under 1100-talet kom cistercienserna och premonstratenserna att utgöra bland de mest spridda och inflytelserika religiösa ordnarna . Även om cistercienserna var en monastisk orden och premonstratenserna en klerikal orden var båda ett resultat av reformrörelser som strävade efter striktare ideal enligt deras respektive regler. För att möjliggöra detta hade de förlagt sina moderkloster i isolerade o

Residual stress analysis of machined lead-free and lead-containing brasses

Legislations demand low lead content in drinking water and low lead leaching from the water supply facilities. Lead-free brass (LFB) can fit in. The benefits of such alloy are acknowledged in both functional and environmental points of view. The relatively high strength of LFB means that the process condition and residual stress generation can be different as compared to the conventional brass. In

Corrosion of bed joint reinforcement in faced single-leaf brick facades - field survey

Bed joint reinforcement consisting of unprotected carbon steel was widely used to bridge windows and other openings in post-war brick buildings in the Scandinavian countries. Today, cracking caused by reinforcement corrosion constitute an increasing technical and economic problem, since removal of the corroding reinforcement can be both labour intensive and costly. Retrofitting measures are usuall

Clay brick masonry facades with cracks caused by corroding bed joint reinforcement – Findings from field survey and laboratory study

Cracking due to corrosion in bed joint reinforcement over openings in masonry facades in the Scandinavian post-war building stock generates increasing retrofitting needs. Removal of the reinforcement can be both costly and labor intensive. The results of retrofitting works are often sub-optimal due to casual inspection practices and lack of knowledge concerning the actual corrosion damage. The obj

Offender Characteristics : A Study of 23 Violent Offenders in Sweden

Twenty-three offenders convicted of homicide or attempted murder/manslaughter, and their respective crimes, were examined to identify any common characteristics. Court documents were assessed, and the most prominent information of the offenders was that they were often single, most of them had no psychiatric diagnoses, the most frequent modus operandi was a knife or sharp weapon (although firearms

Restaurant practices – time, planning, knowledge and dreams

This paper contributes to research on restaurant work, which plays an important role in culinary arts research. The aim of this study was to make visible and elucidate the daily work practices in eight small restaurants in a seasonal tourist destination on the Southeast coast of Sweden. The central methods used were observations and participant observations and interviews, along with an e-mail que

Gammalt folk, hederligt folk eller bara folk – blir ordet folk ett pronomen?

The Swedish word folk (‘people’) is normally considered an ordinary noun. Some sources, however, state that folk is turning into a generic pronoun. This article investigates this assumption. Occurrences of folk in a corpus made up of 45 plays from the period 1730–1997 are analyzed with respect to both syntactic and semantic characteristics, and it is shown that folk is indeed more and more often u

Visual event-related potentials to novel objects predict rapid word learning ability in 20-month-olds

In an event-related potentials (ERP) study, twenty-month-old children (n = 37) were presented with pseudowords to map to novel object referents in five presentations. Quicker attenuation of the visual Negative central component (Nc) to novel objects predicted a larger difference in N400 amplitude between congruous and incongruous presentations of pseudowords at test. Furthermore, better initial re

The QUASAR reproducibility study, Part II : Results from a multi-center Arterial Spin Labeling test-retest study

Arterial Spin Labeling (ASL) is a method to measure perfusion using magnetically labeled blood water as an endogenous tracer. Being fully non-invasive, this technique is attractive for longitudinal studies of cerebral blood flow in healthy and diseased individuals, or as a surrogate marker of metabolism. So far, ASL has been restricted mostly to specialist centers due to a generally low SNR of the
