- The cryptic lifestyle of most fungi necessitates molecular identification of the guild in environmental studies. Over the past decades, rapid development and affordability of molecular tools have tremendously improved insights of the fungal diversity in all ecosystems and habitats. Yet, in spite of the progress of molecular methods, knowledge about functional properties of the fungal taxa is vague and interpretation of environmental studies in an ecologically meaningful manner remains challenging. In order to facilitate functional assignments and ecological interpretation of environmental studies we introduce a user friendly traits and character database FungalTraits operating at genus and species hypothesis levels. Combining the information from previous efforts such as FUNGuild and Fun(Fun) together with involvement of expert knowledge, we reannotated 10,210 and 151 fungal and Stramenopila genera, respectively. This resulted in a stand-alone spreadsheet dataset covering 17 lifestyle related traits of fungal and Stramenopila genera, designed for rapid functional assignments of environmental studies. In order to assign the trait states to fungal species hypotheses, the scientific community of experts manually categorised and assigned available trait information to 697,413 fungal ITS sequences. On the basis of those sequences we were able to summarise trait and host information into 92,623 fungal species hypotheses at 1% dissimilarity threshold.

- The Multi-Blade is a boron-10-based gaseous detector developed for neutron reflectometry instruments at the European Spallation Source in Sweden. The main challenges for neutron reflectometry detectors are the instantaneous counting rate and spatial resolution. The Multi-Blade has been tested on the CRISP reflectometer at the ISIS Neutron and Muon Source in the UK. A campaign of scientific measurements has been performed to study the Multi-Blade response in real instrumental conditions. The results of these tests are discussed in this paper.

Tidskriftsartikel (refereegranskat)abstract
- The Multi-Blade is a Boron-10-based gaseous thermal neutron detector developed to face the challenge arising in neutron reflectometry at neutron sources. Neutron reflectometers are challenging instruments in terms of instantaneous counting rate and spatial resolution. This detector has been designed according to the requirements given by the reflectometers at the European Spallation Source (ESS) in Sweden. The Multi-Blade has been installed and tested on the CRISP reflectometer at the ISIS neutron and muon source in U.K.. The results on the detailed detector characterization are discussed in this manuscript.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Over the last decades, the field of thermal neutron detection has overwhelmingly employed He-3-based technologies. The He-3 crisis together with the forthcoming establishment of the European Spallation Source have necessitated the development of new technologies for neutron detection. Today, several promising He-3-free candidates are under detailed study and need to be validated. This validation process is in general long and expensive. The study of detector prototypes using neutron-emitting radioactive sources is a cost-effective solution, especially for preliminary investigations. That said, neutron-emitting sources have the general disadvantage of broad, structured, emitted-neutron energy ranges. Further, the emitted neutrons often compete with unwanted backgrounds of gamma-rays, alpha-particles, and fission-fragments. By blending experimental infrastructure such as shielding to provide particle beams with neutron-detection techniques such as tagging, disadvantages may be converted into advantages. In particular, a technique known as tagging involves exploiting the mixed-field generally associated with a neutron-emitting source to determine neutron time-of-flight and thus energy on an event-by-event basis. This allows for the definition of low-cost, precision neutron beams. The Source-Testing Facility, located at Lund University in Sweden and operated by the SONNIG Group of the Division of Nuclear Physics, was developed for just such low-cost studies. Precision tagged-neutron beams derived from radioactive sources are available around-the-clock for advanced detector diagnostic studies. Neutron measurements performed at the Source Testing Facility are thus cost-effective and have a very low barrier for entry. In this paper, we present an overview of the project.

- Background: Sportsman's hernia/athletic pubalgia is a recognized cause of chronic groin pain in athletes. Both open and laparoscopic surgical repairs have been described for treatment, but there are no comparative studies. The hypothesis here was that relief of pain would be achieved earlier in patients treated with open minimal suture repair than totally extraperitoneal repair. Methods: A randomized multicentre trial in four European countries was conducted to compare open minimal suture repair with totally extraperitoneal repair. The primary endpoint was complete relief of pain (visual analogue scale (VAS) score 20 or less on a scale from 0 to 100 mm) at 1 month. Secondary endpoints included complications, time to return to sporting activity, and number of patients returning to sport within 1 year. Results: A total of 65 athletes (92 per cent men) with a median age of 29 years were enrolled (31 open repair, 34 totally extraperitoneal repair). By 4 weeks after surgery, median preoperative VAS scores had dropped from 70–80 to 10–20 in both groups (P < 0·001). Relief of pain (VAS score 20 or less) during sports activity 4 weeks after surgery was achieved in 14 of 31 patients after open repair and 24 of 34 after totally extraperitoneal repair (P = 0·047). Return to full sporting activity was achieved by 16 and 18 patients respectively after 1 month (P = 0·992), and by 25 versus 31 after 3 months (P = 0·408). Conclusion: Totally extraperitoneal repair was less painful than open repair in the first month, but otherwise both procedures were similarly effective in treating chronic pain due to sportsman's hernia.
