Evolution of collective and noncollective structures in Xe 123
An experiment involving a heavy-ion-induced fusion-evaporation reaction was carried out where high-spin states of Xe123 were populated in the Se80(Ca48,5n)Xe123 reaction at 207 MeV beam energy. Gamma-ray coincidence events were recorded with the Gammasphere Ge detector array. The previously known level scheme was confirmed and enhanced with the addition of five new band structures and several inte
Nanowire Solar Cells : A New Radiation Hard PV Technology for Space Applications
Radiation hard thin-film solar cell technologies are necessary in order to achieve a step forward in the specific power of solar arrays for space applications. In this article, we analyze the degradation of nanowire (NW) solar cells under high energy particles. GaAs NW solar cells have been irradiated with protons of 100 and 350 keV at different fluences. The radiation hardness of the NW solar cel
Electric bike navigation behaviour in pedestrian crowds
This study investigates the influence of pedestrian crowdedness on e-bike navigation behaviour in a controlled field experiment. The dataset includes a total of 1520 trajectories, including 18 pedestrians and one e-bike at a time. Based on the e-bike navigation through the pedestrians, the so-called “hindrance” concept was used to classify the data into two phases: passing (same-direction encounte
Development and initial testing of a new instrument to measure the experience of eczema control in adults and children : Recap of atopic eczema (RECAP)
Background: Eczema control has been identified as an important outcome by key stakeholders in eczema research (including patients, carers, healthcare professionals and researchers) but no validated instruments for the domain have been identified. Objectives: To develop a measurement instrument to capture a patient's perspective of eczema control that is suitable for use in eczema clinical trials.

LL-37 and Double-Stranded RNA Synergistically Upregulate Bronchial Epithelial TLR3 Involving Enhanced Import of Double-Stranded RNA and Downstream TLR3 Signaling
The human host defense peptide LL-37 influences double-stranded RNA signaling, but this process is not well understood. Here, we investigate synergistic actions of LL-37 and synthetic double-stranded RNA (poly I:C) on toll-like receptor 3 (TLR3) expression and signaling, and examine underlying mechanisms. In bronchial epithelial BEAS-2B cells, LL-37 potentiated poly I:C-induced TLR3 mRNA and prote
Annie Marion Maclean : Kvinnan i industrisamhället
För att sociologi skulle kunna vara ett eget ämne och utvecklas behövde det en empirisk ansats. Annie Marion MacLean påbörjade sina doktorandstudier på Chicago universitet 1896. Med över 200 publicerade manuskript var MacLean en pionjär i utvecklingen av Chicagoskolans etnografiska arbete och utvecklingen av både sociologisk arbetslivsforskning och urban sociologi. Hennes arbete är högst relevant
A Randomised Controlled Trial of Consent Procedures for the Use of Residual Tissues for Medical Research : Preferences of and Implications for Patients, Research and Clinical Practice
BACKGROUND: Despite much debate, there is little evidence on consequences of consent procedures for residual tissue use. Here, we investigated these consequences for the availability of residual tissue for medical research, clinical practice, and patient informedness.METHODS: We conducted a randomised clinical trial with three arms in six hospitals. Participants, patients from whom tissue had been
Trends in cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for the treatment of synchronous peritoneal carcinomatosis of colorectal origin in the Netherlands
BACKGROUND: Population-based data on the percentage of colorectal cancer (CRC) patients with synchronous peritoneal carcinomatosis (PC) being treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are currently lacking. The current population-based study describes trends in the use of CRS-HIPEC in the Netherlands, one of the first countries where CRS and HIP
Stability of oxaliplatin in chloride-containing carrier solutions used in hyperthermic intraperitoneal chemotherapy
PURPOSE: Oxaliplatin is increasingly becoming the chemotherapeutic drug of choice for the treatment of peritoneal malignancies using cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). Oxaliplatin is unstable in chloride-containing media, resulting in the use of 5% dextrose as the carrier solution in these procedures. Exposure of the peritoneum to 5% dextrose during pe
Spinal cord grey matter segmentation challenge
An important image processing step in spinal cord magnetic resonance imaging is the ability to reliably and accurately segment grey and white matter for tissue specific analysis. There are several semi- or fully-automated segmentation methods for cervical cord cross-sectional area measurement with an excellent performance close or equal to the manual segmentation. However, grey matter segmentation
Phobos base : Concept of operations and architecture for a permanent human presence on the Martian moon Phobos
This paper is based on the work done for the 2017 AIAA Student Design Competition-Human Spaceflight: Phobos Base. One of humanity's major challenges when travelling to Mars is represented by the existence of an atmosphere around the red planet. In fact, even though the Martian atmospheric density is only about 1% of that of Earth, the entry, descent and landing (EDL) procedure for large payloads i
Physiotherapy interventions encouraging frequent changes of the body position and physical activity for infants hospitalised with bronchiolitis : an internal feasibility study of a randomised control trial
BACKGROUND: The effect of a treatment that includes frequent changes of the body position for infants with bronchiolitis has not been evaluated, although it is often used in Swedish hospitals. Because of this, a randomised control trial (RCT) has begun with the aim to evaluate this treatment, comparing the effect of an individualised physiotherapy intervention, a non-individualised intervention, a
Perspektiv på offentlig förvaltning : Teori i praktiken
Resultatet av politiska beslut påverkas i stor utsträckning av vad som sker i den offentliga förvaltningen. Att studera hur förvaltningen styrs och hur den fungerar är därför helt centralt inom samhällsvetenskaperna. För att analysera den offentliga förvaltningens komplexitet och mångfald behövs ett brett spektrum av teorier, men beroende på vilken teori som används kommer både frågeställningar oc
Seeing lockdown through the eyes of children from around the world : Reflecting on a children's artwork project
The COVID-19 pandemic created new challenges for children including access to education and limiting social and emotional connections to extended family, friends, and the community. Globally, opportunities for sharing children’s self-reported experiences during lockdown were limited. The primary aim of this project was to create an art-eBook that reflects children’s experiences of life during the
Outcomes of the Tree Theme Method versus regular occupational therapy : A longitudinal follow-up
Introduction: Depression and anxiety disorders affect individuals' everyday lives, and treatments that can help them to perform everyday occupations are needed. Occupational therapy for this group has been evaluated from a short-term perspective but not from a long-term perspective; further research is thus warranted. The aim of the study was to investigate the longitudinal outcomes of the Tree Th
Reduced fracture incidence in patients having surgery for primary hyperparathyroidism
Objective: The indication of surgery in primary hyperparathyroidism has been controversial, as many patients experience mild disease. The primary aim was to evaluate fracture incidence in a contemporary population-based cohort of patients having surgery for primary hyperparathyroidism. The secondary aim was to investigate whether preoperative serum calcium, adenoma weight or multiglandular disease

Changes in Vitamin D Status in Overweight Middle-Aged Adults with or without Impaired Glucose Metabolism in Two Consecutive Nordic Summers
Background. Sun exposure is the main driver of vitamin D synthesis. High latitude, obesity, and type 2 diabetes mellitus (T2DM) are all risk factors for vitamin D deficiency. However, the seasonal variation in vitamin D concentrations (25[OH]D) in such populations before and after sun exposure during the summer is unknown. Therefore, we investigated 25[OH]D status before and after two consecutive
