Book (other academic/artistic)abstract
- Att undervisa i de naturvetenskapliga ämnena (NO) i de tidiga skolåren är ett utmanande, spännande och roligt uppdrag. Dessa ämnen spänner dock över stora innehållsområden och därför kan det vara svårt att få en överblick och välja ett innehåll som är lämpligt för åldersgruppen.Den här boken hjälper läraren att få grepp om det viktigaste innehållet i de naturvetenskapliga ämnena. Naturvetenskapens grundläggande och bärande idéer förklaras detaljerat och belyses med en rad konkreta och vardagliga exempel. Innehållet diskuteras i förhållande till Läroplan för grundskolan, förskoleklassen och fritidshemmet (Lgr 11).Boken kan, gärna i kombination med boken Naturvetenskapens bärande idéer i praktiken, användas både som kurslitteratur för blivande lärare och som ämnesfördjupning för verksamma lärare.Den 3:e upplagan har reviderats i förhållande till ändringarna i kursplanerna 2020.

Newly trained operating room nurses' experiences of nursing care in the operating room
- 2020

Journal article (peer-reviewed)abstract
- There is limited research on nurses' experiences of nursing care in the operating room. The operating room nurses' responsibility is to ensure good nursing care before, during and after surgery. In an increasingly technological health care environment, there is always a risk of turning the focus away from nursing care towards technology and medicine. Integration of past experiences into the role as an operating room nurse becomes a challenge for those who recently worked as general nurses. The present study aimed to explore newly trained operating room nurses' experiences of nursing care in an operating room. Semi-structured interviews were performed with ten operating room nurses with a maximum three years' work experience from an operating room. The interviews were subjected to qualitative content analysis. The findings revealed three themes describing operating room nurses' searching for their new role. They experienced a gap between theory and practice, felt alone and insignificant and had to find their own place. The operating room nurses' experienced threats to safe nursing when they lacked time for the patients as well as for their own recovery, and they lacked feedback in order to improve care. They ensured security for patients by establishing one-to-one contact, protecting patients' well-being and working in teams for the patients' best interest, participants also focused on the task at hand instead of the patient as a person. New ways of organising work in operating units, and well-functioning teams can be a key to a successful integration of experiences from ward nurse to an operating room nurse, and provide support so that they feel more visible, at ease and safe in their new profession.

Using a look-up table technique and finite element calculations for quick detection of stiff inclusions in silicone rubber
- 2020

Journal article (peer-reviewed)abstract
- Purpose: The aim of the study was to show that a new method, using a look-up table technique, can be used to detect the presence and position of an inclusion embedded in a tissue-like material. Due to the time-consuming nature of the finite element (FE) method or FEM, real-time applications involving FEM as part of a control loop, are traditionally limited to slowly varying systems. By using a simplified two-dimensional FE model and a look-up table, we show by simulations and experiments that it is possible to achieve reasonable computational times in a tactile resonance sensor application.Design/methodology/approach: A piezoelectric disk was placed in the center of a silicone rubber disk (SRD) with viscoelastic properties, where it acted as both sensor and actuator and dissipated radial acoustic waves into the silicone. The look-up table was constructed by calculating the radial Lamb wave transition frequencies in the impedance frequency response of the sensor while varying the position of an inclusion. A position-matching algorithm was developed that matched measured and calculated Lamb wave transitions and thereby identified the presence and position of an inclusion.Findings: In an experiment, the position of a hard inclusion was determined by measuring the Lamb transition frequencies of the first radial resonance in two SRDs. The result of the matching algorithm for Disk 1 was that the matched position was less than 3% from the expected value. For Disk 2, the matching algorithm erroneously reported two false positions before reporting a position that was less than 5% from the expected value. An explanation for this discrepancy is presented. In a verifying experiment, the algorithm identified the condition with no inclusion present.Originality/value: The approach outlined in this work, adds to the prospect of developing time-sensitive diagnostic instruments. This approach has the potential to provide a powerful technique to quickly present spatial information on detected tumors.

Medtech innovation guide : an empiric model to support medical technology innovation
- 2022

Journal article (peer-reviewed)abstract
- Innovation has become increasingly important for most industries to cope with rapid technological changes as well as changing societal needs. Even though there are many sectors with specific needs when it comes to supporting innovation, the medical technology sector is facing several unique challenges that both increases the lead-time from idea to finished product and decreases the number of innovations that are developed. This paper presents a proposed innovation guide that has been developed and evaluated as a support for the innovation process within medical technology research. The guide takes the unique characteristics of the medical technology sector into account and serves as a usable guide for the innovator. The complete guide contains both a structure for the process and a usable web application to support the journey from idea to finished products and services. The paper also includes a new readiness level, Sect. 4.2 to provide support both when developing and determining the readiness for clinical implementation of a medical technology innovation.
