We report on the use of a sacrificial AlAs segment to enable substrate reuse for nanowire synthesis. A silicon nitride template was deposited on a p-type GaAs substrate. Then a pattern was transferred to the substrate by nanoimprint lithography and reactive ion etching. Thermal evaporation was used to define Au seed particles. Metalorganic vapour phase epitaxy was used to grow AlAs-GaAs NWs in the
The fabrication of complex nanoscale electronics with reduced dimensions poses challenges on novel techniques to accurately determine fundamental electronic parameters. In this article, we present a universal contactless method based on Raman scattering for measuring the mobility and hole concentration independently in GaAs:Zn and Mn ion-implanted GaAs:Zn nanowires, potentially of great interest f
This article aims to critically analyse established integration models and look into how migrants/diasporas actively create practices of encounter, dialogue and mutual learning within host societies. This paper is based on fieldwork in a Swedish local space (Malmö) and explores the diversity of artistic activism of the Palestinians in Sweden in order to analyse its consequences on the concept of i
Landscape is an important public interest with social, cultural, ecological, and environmental dimensions. It is central to the formation of local cultures and contributes to human well-being. Some areas are protected by supranational agreements that have significant international value. The European Landscape Convention (ELC) calls for integrating landscape considerations into other policy areas
Background Coronary artery disease is the primary etiology for sudden cardiac arrest in adults, but potential differences in the incidence and utility of invasive coronary testing between resuscitated men and women have not been extensively evaluated. Our aim was to characterize angiographic similarities and differences between men and women after cardiac arrest. Methods and Results Data from the
OBJECTIVES: To assess whether the triage model Sepsis Alert for Emergency Departments results in improved initial care of patients with severe infections. DESIGN: Interventional study comparing patient care before and after the start of a new triage model, including 90-day follow-up. SETTING: Eight emergency departments in Skåne County, Sweden. SUBJECTS: Patients with suspected severe infection. I
Background: A circumferential resection margin (CRM) of 1·0 mm or less after rectal cancer surgery is thought to increase the risk of local recurrence (LR). This retrospective population-based study examined how CRM distance affects the LR risk. Methods: Data from the Swedish Colorectal Cancer Registry were used in a retrospective analysis of rectal cancers resected between 2005 and 2013. The prim
Combatting human smuggling and human trafficking has been one of the priority objectives of the EU and its Member States in their efforts to decrease the number of migrants arriving in EU territory. The development of strong cooperation with third-countries has been considered indispensable to the effectiveness of what is often described in EU documents as the ‘fight’ against human trafficking and
Backgrounds and Purpose- Although new methods for genetic analyses are rapidly evolving, there are currently knowledge gaps in how to detect Mendelian forms of stroke. Methods- We performed whole-exome sequencing in 22 probands, under 56 years at their first ischemic stroke episode, from multi-incident stroke families. With the use of a comprehensive stroke-gene panel, we searched for variants in
Statligt stöd till arbetsgivare för att anställa arbetssökande har genom tiderna haft olika namn. När denna undersökning gjordes kallades de bland annat nystartsjobb, instegsjobb och lönebidrag. Bidragen har ständigt diskuterats och reformerats. Kvantitativa effektundersökningar om hur flest sökande kommer i arbete är vanliga. Denna bok har en annan ingång. Här återges material från
Plasma phosphorylated tau181 (P-tau181) might be increased in Alzheimer’s disease (AD), but its usefulness for differential diagnosis and prognosis is unclear. We studied plasma P-tau181 in three cohorts, with a total of 589 individuals, including cognitively unimpaired participants and patients with mild cognitive impairment (MCI), AD dementia and non-AD neurodegenerative diseases. Plasma P-tau18
The first ab initio aspherical structure refinement against experimental X-ray structure factors for polypeptides and proteins using a fragmentation approach to break up the protein into residues and solvent, thereby speeding up quantum-crystallographic Hirshfeld atom refinement (HAR) calculations, is described. It it found that the geometric and atomic displacement parameters from the new fragHAR
Objectives: This study aimed to investigate the occurrence of suicidal ideation and associated factors in older persons with dementia living at home in eight European countries, and its association with quality of life. Furthermore, changes in suicidal ideation over time were investigated. Methods: This cohort study (n = 1,223) was part of the European “RightTimePlaceCare” project conducted in 201
Over the last 50 years, the production and consumption of chicken meat have soared in Bolivia. This paper analyzes the political, economic, and cultural developments that have led to the popularity of chicken meat in this country. It also asks who has benefitted from this success story. The author uses data from one year of multi-sited ethnographic fieldwork in Bolivia in order to give an account
The Kumamoto area includes 11 municipalities and a population of about one million. The area represents the largest total use of groundwater in Japan. The main recharging area for this groundwater used to be paddy fields for rice production located along the mid-stream section of the Shirakawa River. In the past few decades, the area of paddy fields has rapidly decreased due to the Japanese govern
The electric field response of the lead-free solid solution (1-x)Bi0.53Na0.47TiO3-xBaTiO3 (BNT-BT) in the higher BT composition range with x = 0.12 was investigated using in situ synchrotron X-ray powder diffraction. An introduced Bi-excess non-stoichiometry caused an extended morphotropic phase boundary, leading to an unexpected fully reversible relaxor to ferroelectric (R-FE) phase transformatio
