- A liquid-xenon-jet laser-plasma source for extreme-ultraviolet (EUV) and soft-x-ray generation has been characterized. Being a source candidate for EUV lithography (EUVL), we especially focus on parameters important for the integration of the source in EUVL systems. The deep-ultraviolet (DUV) out-of-band radiation (=120–400 nm) was quantified, to within a factor of two, using a flying-circus tool together with a transmission-grating spectrograph resulting in a total DUV conversion efficiency (CE) of ~0.33%/2sr. The size and the shape of the xenon plasma was investigated using an in-band-only EUV microscope, based on a spherical Mo/Si multilayer mirror and a charge-coupled device detector. Scalability of the source size from 20–270 µm full width at half maximum was shown. The maximum repetition-rate sustainable by the liquid-xenon-jet target was simulated by a double-pulse experiment indicating feasibility of >17 kHz operation. The xenon-ion energy distribution from the plasma was determined in a time-of-flight experiment with a Faraday-cup detector showing the presence of multi-kilo-electron-volt ions. Sputtering of silicon witness plates exposed to the plasma was observed, while a xenon background of >1 mbar was shown to eliminate the sputtering. It is concluded that the source has potential to meet the requirements of future EUVL systems.

- Augmented Reality (AR) has developed rapidly inrecent years and it is about to become a mainstream technology.We are witnessing how emerging technologies such as AR has been introduced and today widely applied in engineering education.The turmoil caused by the COVID-19 pandemic has in many ways highlighted the importance of AR technology for collaboration and remote assistance of frontline workers. Enabling experts to be much more productive in helping to debug problems and resolve production issues remotely. This kind of hands-on support and tutoring opportunities play well into the possibilities embedded in a more digitalized approach to engineering education. Still, both industries and universities are exploring ways to enhance the value-added credentials that come along with an integration and investment of AR. This paper set out to understand what type of assessment that are used to drive learning performance amongstudents in engineering education.

- The purpose of this study was to Survey the prevalence of pain in the cervical and thoracic spine (C2-T7) in persons with and Without lateral elbow pain. Thirty-one subjects with lateral elbow pain and 31 healthy controls participated in the study. The assessment comprised a pain drawing, provocation tests of the cervical and thoracic spine, a neurodynamic test of the radial nerve, and active cervical range of motion. Seventy percent of the subjects with lateral elbow pain indicated pain in the cervical or thoracic spine, as compared to 16% in the control group (p< ;0.001). The frequency of pain responses to the provocation tests of the cervical and thoracic spine was significantly higher (p< ;0.05) in the lateral elbow pain (LEP) group, as was the frequency of pain responses to the neurodynamic test of the radial nerve (p< ;0.001). Cervical flexion and extension range of motion was significantly lower (p< ;0.01) in the LEP group. The results indicate a relation between lateral elbow pain and pain in the vertebral spine (C2-T7). The cervical and thoracic spine should be included in the assessment of patients with lateral elbow pain.

Intended Involvement – How Public Organizations Struggle to Become Co-producers of New Public Values
- 2024

Tidskriftsartikel (refereegranskat)abstract
- The paper is guided by the question of how public organizations can adapt to include citizens as co-producers of public values. To answer it, eleven researchers and civil servants, all involved in the transformation of a collaborative platform encompassing a university and four different public organizations, formed a collaborative and boundary-spanning author. Building on personal expertise and situated organizational experiences we conclude that public organizations do not adapt except for specific confined areas where they can still control and command outcomes important to them. Hence, public organizations struggle to become co-producers of new public values. From the process, we also conclude that academics and civil servants together writing an academic article cannot be viewed as a fertile common ground for equal collaboration and co-production. Nevertheless, it might still work as an interesting boundary-spanning activity for arriving at shared understandings and important insights on for instance why organizational moves from intended to actual involvement appear difficult.
