Forskningsöversikt (refereegranskat)abstract
- This article suggests algorithms for diagnosis and treatment of scaphoid fractures. A clinical suspected scaphoid fracture without signs of fracture on conventional radiographs should have a supplementary MRI done within 5-7 days. Displaced fractures and all proximal fractures should be classified by CT. Fracture union should be evaluated by CT. 90 procent of non- or minimally displaced waist fractures are healed after 6 weeks of conservative treatment. Non- or minimally displaced fractures with signs of instability can be treated conservatively, but require prolonged immobilisation. Fractures with a displacement ≥1,5 mm as well as the majority of proximal scaphoid fractures should be treated surgically with internal fixation.

- This chapter introduces a selection of novel and emerging concepts in ambient pressure X-ray spectroscopies. Technical considerations and first photoemission experiments performed in and above 1 bar pressure are described. Then, X-ray spectroscopy experiments that provide high lateral (microscopy) and depth (X-ray standing-waves) resolution in ambient environments are discussed. The final part of the chapter introduces recent developments in multimodal instrumentation, such as the combination of ambient pressure X-ray Photoelectron Spectroscopy with Infrared spectroscopy and X-ray scattering.

- Objective: To compare the outcomes of two emergency treatment procedures to alleviate pain from localised symptomatic apical periodontitis: complete chemo‐mechanical disinfection (CMD) of the root canal system, or removal of necrotic tissue from the pulp chamber (RNT), that is without instrumentation of the root canals. Methods: Fifty‐seven consecutive patients from the emergency clinic at Malmö University met the inclusion criteria: spontaneous pain and/or pain on percussion and palpation, non‐bleeding pulp in the canal orifice, pain ≥4 on a Numeric Rating Scale and ≥18 years of age. The diagnosis was symptomatic apical periodontitis, in the absence of swelling and/or fever. Pre‐operative pain levels and intake of analgesics were registered. The patients were randomised to one of the two treatment groups. Three to five days post‐operatively, the patients were contacted by telephone and asked to grade their current pain level and report any post‐operative intake of analgesics and antibiotics. Results: Of the patients treated with CMD of the root canal system, 26/30 (87%) reported satisfactory pain relief, compared with 22/27 (81%) of those treated by RNT. There was no mean difference in pain relief between the two groups (P = 0.879). Post‐operatively, 37% in each group reported using analgesics and one in each group reported using antibiotics. Conclusion: Three to five days after treatment, a majority (>80%) in both groups reported adequate pain relief, in some cases in combination with analgesics. Removal of necrotic and infected tissue from the pulp chamber might therefore be a cost‐effective emergency treatment alternative to complete chemo‐mechanical disinfection.

- Single-atom catalysts have recently been subject to considerable attention within applied catalysis. However, complications in the preparation of well-defined single-atom model systems have hampered efforts to determine the reaction mechanisms underpinning the reported activity. By means of an atomic layer deposition method utilizing the steric hindrance of the ligands, isolated Fe1O3 motifs were grown on a single-crystal Cu2O(100) surface at densities up to 0.21 sites per surface unit cell. Ambient pressure X-ray photoelectron spectroscopy shows a strong metal-support interaction with Fe in a chemical state close to 3+. Results from scanning tunneling microscopy and density functional calculations demonstrate that isolated Fe1O3 is exclusively formed and occupies a single site per surface unit cell, coordinating to two oxygen atoms from the Cu2O lattice and another through abstraction from O-2. The isolated Fe1O3 motif is active for CO oxidation at 473 K. The growth method holds promise for extension to other catalytic systems.

Portable rescue device and a method for locating such a device
- 2007
-
Patent (populärvet., debatt m.m.)abstract
- A portable rescue device and a method for locating, by means of a first rescue device set in a search mode, a second rescue device set in a distress mode. In the method, a distress signal carrying a device identification is received from said second rescue device. A first bearing and a second bearing to the second rescue device are obtained. The first and second bearings are taken from a first and a second position, respectively. A distance between these positions is determined. A current distance and a current bearing to the second rescue device are determined on basis of the first and second bearings and the distance. The current bearing and the current distance are communicated to a user of the first rescue device. The portable rescue device is used for performing the method and for that purpose it includes a first communication unit for distress signal transmission and reception; a compass; a processor; a user interface; and a mode switch for switching between a search mode and a distress signal mode. The first communication device has an antenna structure that provides directional capability.

Unga resenärers upplevelser av kollektivtrafiken
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Syftet med studien var att få en fördjupad kunskap om faktorer som påverkar unga resenärers attityd till och upplevelse av kollektivresan. Kunskap som kan förklara varför resenären fattar sina val att resa eller inte resa kollektivt nu och i framtiden undersöktes genom tre fokusgruppsintervjuer med totalt 24 unga i åldern 18–20 år. Undersökningen gjordes under hösten 2016 och var ett samarbete med Västtrafik i Västra Götalandsregionen.Resultaten kan delas in i två huvudteman: A) upplevelsen av resan och dess relationer, som beskriver situationen, vad som sker och hur det hanteras och B) uppfattningar om resan och dess potential som handlar om resenärens värderingar och behov. Vi vill påstå att ungdomars val att vara kvar eller att lämna kollektivtrafiken efter skoltiden, bland annat påverkas av deras upplevelser och uppfattningar.Resultaten av denna studie lyfter fram behovet av att se resans innehåll och resenärens upplevelse som väsentlig. Resan kan bli värdefullistället för bortkastad tid om upplevelsen kan förbättras så att resenärerna kan koppla av och få vara ifred. Trängseln och resans ryckighet är ett problem och en sittplats behövs då man är trött, vill läsa läxor eller använda bägge händerna med mobilen. Trängseln leder också till ett respektlöst beteende mellan passagerare. Det finns risk för att ökade krav på kostnadseffektivt i kollektivtrafiken leder till ökad trängsel vilket sänker attraktiviteten i framtiden. Föraren har en viktig roll för upplevelsen av resan, de unga önskar en professionell förare som kör mjukt med ett kundorienterat bemötande.Ett förvånande resultat var att de unga resenärerna var så positiva till kollektivtrafiken och att Västtrafik fick ett bra betyg med tanke på att ungdomar ofta lämnar kollektivtrafiken efter skoltiden. Deltagarna hade många förslag på förbättringar som redovisas i rapporten och det framgick att brist på information kunde leda till upplevelser av opålitlighet och negativt bemötande.

Tidskriftsartikel (refereegranskat)abstract
- Two high-k dielectric materials (Al2O3 and HfO2) were deposited on n-type (100) and (110) InAs surface orientations to investigate physical properties of the oxide/semiconductor interfaces and the interface trap density (D-it). X-ray photoelectron spectroscopy analyses (XPS) for native oxides of (100) and (110) as-grown n-InAs epi wafers show an increase in As-oxide on the (100) surface and an increase in InOx on the (110) surface. In addition, XPS analyses of high-k (Al2O3 and HfO2) on n-InAs epi show that the intrinsic native oxide difference between (100) and (110) epi surfaces were eliminated by applying conventional in-situ pre-treatment (TriMethyAluminium (TMA)) before the high-k deposition. The capacitance-voltage (C-V) characterization of HfO2 and Al2O3 MOSCAPs on both types of n-InAs surfaces shows very similar C-V curves. The interface trap density (D-it) profiles show D-it minima of 6.1 x 10(12/)6.5 x 10(12) and 6.6 x 10(12)/7.3 x 10(12) cm(-2) eV(-1) for Al2O3 and HfO2, respectively for (100) and (110) InAs surfaces. The similar interface trap density (D-it) on (100) and (110) surface orientation were observed, which is beneficial to future InAs FinFET device with both (100) and (110) surface channel orientations present.
