Reports (other academic/artistic)abstract
- PIXE-analyser kan utföras med utvecklad analysuppställning med noggrannhet och precision av c:a 10 % och med hög analyskapacitet. Ett dataprogram för evaluering av räntgenspektra presenteras. Inverkan av provtjocklek vid PIXE-analys av inhomogena prov har studerats och korrektioner föreslås. Fluorinnehållet i filterprov har bestämts, samtidigt med PIXE-analys, genom utnyttjande av en kärnfysikalisk reaktion som ger resultat med god noggrannhet och precision. Svetsaerosoler har karakteriserats m.h.a. PIXE, ESCA och TEM/EDAX. En uppställning för insamling av svetsaerosoler under utveckling och hittillsvarande resultat indikerar representativ provinsamling med god reproducerbarhet.

Conference paper (other academic/artistic)abstract
- ‘Close-to-practice research’ has received increased attention across the Nordic countries. Following the British Education Research Association (BERA), the notion of ‘close-to-practice research’ is used to refer to educational research that is based on problems in practice, often involves researchers working in partnership with practitioners in schools and addresses issues of relevance to practitioners. This roundtable focuses on how close-to-practice research can contribute to the knowledge base of the teaching profession by bringing together perspectives from didactics, school improvement and educational policy. More specifically, the interest is directed toward what characterizes the knowledge produced through practice-based research that may have significance for teachers' professional knowledge base and practice. The roundtable conversation builds on a previous analysis of what kinds of knowledge products are generated in didactic close-to-practice research where teachers and researchers work together within the research environment Stockholm Teaching & Learning Studies. As a result of this analysis a typology of knowledge products was proposed including: (i) descriptions of knowing, (ii) teaching design, (iii) didactic examples and (iv) methodological tools. It has been proposed that additional knowledge products may be developed, such as artifacts to be used in teaching (e.g. lesson plans, visual representations). The roundtable will include the following points of discussion: 1) a brief presentation of the typology, 2) challenging and developing the typology of knowledge products proposed by previous research by investigating different cases of close-to-practice research from traditions of action research and practice-developing research within subject-didactics, and 3) discussing how the notion of knowledge products may contribute to advancing the conversation on cumulativity in the field of educational research in general, and in relation to syntheses of close-to-practice research in particular. The participants will be engaged in conversations on the desirability and feasibility of striving towards cumulativity.

Reports (other academic/artistic)abstract
- In a laboratory study the impact of the surrounding light on alertness was study. Two types oflight sources were examined, LEDs and T5 fluorescent tubes. The illuminance level in theworking area was kept constant (500 lx), while the surrounding light was varied between 100och 350 cd/m2. Subjective ratings of the emotional status and the experience of the lightingenvironment as well as physiological measurements of cortisol and melatonin levels in thesaliva were conducted. The results show that the higher the surrounding light the higher thephsysiological cortisol levels. There were no significant differences in the experience of thelight, except that the LED light source were a little bit more bright. It should, however, bestressed that the light sources were very well shielded and no glare were at hand.The resultsshould be interpreted with caution, but with the chosen LED light sources no harmful effectswere seen in comparison to fluorescent tubes. LED may be seen as a good alternative as longas the lighting design is done careful so that glare is avoided. The study comprised 42 subjectsbetween 18-68 years of age, mean age 43 years. Preliminary results have been presented atEnergitinget 2010 and at CEEBELs conference in Katrineholm. During the spring a series ofpresentations will be held.

Mat, hälsa och oregelbundna arbetstider
- 2005

Reports (other academic/artistic)abstract
- Maten, måltiden och ätandet är en av grundförutsättningarna för god hälsa. Ensidigt ätande, oregelbundet ätande och småätande är direkta riskfaktorer för ohälsa på både kort och lång sikt. På kort sikt är övervikt ett stort problem. På lång sikt utvecklas ett livsstilsätande under arbetstid som, utöver övervikt, ökar risken för bland annat diabetes samt hjärt- och kärlsjukdomar. Vad man äter och hur man kan planera sitt ätande hänger samman med utbudet av mat och måltider på arbetsplatsen eller i grannskapet. Måltiderna är ofta stressade av de arbetstider man har. Det måste gå snabbt att skaffa fram maten och snabbt att äta den. Ramen kring måltiden, den goda maten och samvaron reduceras ofta till en fråga om att stilla hungern. Det oregelbundna ätandet kännetecknas av småätande av söta saker, smakportioner eller feta och ensidiga matportioner. Den kunskap denna studie av måltidsituationen lett fram till visar på problemområden som har med arbetsorganisationen, med mat- och måltidsutbudet, med det nödvändiga och det goda ätandet samt med hälsan att göra.
