- Mannequin properties desired for ergonomic evaluation of car interiors Lars Hansson, Kenneth Holmqvist, Simon Sjölander, Giovanni Distante, Guiseppe Andreoni, Nicholas Colford, Tomas Engström, Gert-Åke Hansson, Roland Kadefors, Patric Petersson, Camilla Rigotti, Lena Sperling, Anders Sundin, Per Östman, Roland Akselsson The aim of this study was to simulate a future mannequin with real people in order to find characteristics necessary for ergonomic evaluation of comfort in car interiors. We argue that the mannequin should ideally perform natural movements, collision detection, a biomechanical model, and eyes. Optional improvements to the mannequin involve muscles and a heart. We also discuss the user interface to the mannequin and means to present mannequin data.

- A study of the detection limits for the elements with Z = 15-92 in thick target steel surfaces using proton-induced X-ray technique has been performed. Samples were irradiated with a broad proton beam of 2 mm diameter and the X-rays were detected by a Si(Li) detector. Detection limits at levels down to the order of 10 ppm were achieved with simultaneous measurement of several elements. Mylar and chromium absorbers were introduced in front of the semiconductor detector and irradiations at two different proton energies (1.0 and 2.5 MeV) were carried out in order to elucidate their effects on detection limits. The results are valid for microbeam analysis.

Proton-Induced X-Ray Emission in the Trace Analysis of Human Tooth Enamel and Dentine
- 1976

Ingår i: International Journal of Applied Radiation and Isotopes. ; 27:5-6, s. 279-290
-
Tidskriftsartikel (refereegranskat)abstract
- In this study the feasibility of applying proton-induced X-ray emission spectroscopy (PIXE) to the trace element analysis of human tooth enamel and dentine is investigated. Detection limits on the order of 1–10 ppm are obtained. Depth yields for different elements and proton energies are discussed. Enhancement calculations show that the effect for PIXE analysis is less important than for X-ray induced X-ray analysis. However, for elements with an absorption edge just below an intense X-ray line from a major element the enhancement effect is significant, and, due to the 40% calcium in the enamel matrix, it is estimated to be 15% for potassium. The importance of a smooth sample surface is discussed.

Aerosol Sampling and Samplers Matched to PIXE Analysis
- 1984
-
Ingår i: Nuclear Instruments and Methods in Physics Research B. ; 3:1-3, s. 425-430
-
Tidskriftsartikel (refereegranskat)abstract
- The PIXE method constitutes a tool for fast, reliable multi-elemental analysis of small samples. These properties are very attractive in aerosol sciences and in aerosol monitoring programmes. Thus PIXE allows the use of small samplers which are easy to deploy and could be operated for long periods even at more or less remote sites. For working environment aerosols, samplers with time resolution can be, and in a few cases are, designed for personal continuous sampling in the breathing zone. For both practical and economical reasons, PIXE, in many applications, facilitates the gathering of multi-elemental information about aerosols with more detailed size, site and time resolution when compared with conventional techniques. Conditions for maximum exploitation of the PIXE technique in aerosol research are development of suitable samplers, optimal sampling strategies and adequate analytical procedures taking the unique properties of PIXE into consideration. These developmental tasks require intense interactions between several research and development disciplines. In this paper, the state of the art of samplers matched to the PIXE method is reviewed.
