15.	Johansson, B., et al. (author) Detection thresholds : Effect of stimulus presentation order and addition of blanks I. Odor of pentanal and hexanol 1973 In: Lebensmittel-Wissenschaft + Technologie. - 0023-6438 .- 1096-1127. ; 6:4, s. 115-122 Journal article (peer-reviewed)abstract Detection thresholds for the odor of pentanal and hexanol were determined using a method of constant stimuli with single sample presentations. The effects of addition of blanks and of order of sample presentation (ascending, descending, randomized) were studied for grouped threshold values. Moreover, differences between groups of subjects with different frequencies of false alarm, and between males and females were studied. Preceding blanks, added to the ascending series, but unknown to the subjects, caused a significant decrease in threshold values for all groups of subjects. The decrease was probably mainly an anticipation effect caused by the information to the subjects. For pentanal, the ascending concentration order gave a significantly lower threshold value than the descending or randomized orders, between which there was no significant difference. For hexanol, in general, the differences among presentation orders were not significant. A sufficient explanation for this unexpected difference between the two compounds cannot be given. For each compound, subjects with lower frequencies of false alarm had, in all experimental series, significantly higher threshold values than subjects with higher frequencies. Females had significantly lower threshold values than males. © 1973 Forster-Verlag AG, Zürich.

18.	Johansson, Thomas B, et al. (author) Analytical Use of Proton-Induced X-Ray Emission 1976 In: Journal of Radioanalytical and Nuclear Chemistry. - 0236-5731. ; 32:1, s. 207-217 Journal article (peer-reviewed)abstract Proton-induced X-ray emission, PIXE, is capable of simultaneous quantitative determination of 10-15 elements. An introduction to the physical properties of the method is given and detection limits are shown for a routine analysis of a thin aerosol sample. Examples of applications to both thick and thin samples are presented. Human tooth dentine is analysed for lead, with simple sample preparation, indicating lead values of a few ppm for Swedish children. Quantitative analyses of several other elements are obtained simultaneously. Cascade impactors axe used for sampling aerosols in work environment during welding operations giving information of size distribution and concentrations of the elements present. The aerosol is dominated by particle sizes between 0.5 and 2 um as measured by the impactor, but the size distributions are different for different elements and welding techniques and depend on the distance from the welding source. The relative abundance of the elements found in the aerosol indicates the presence of fractionation mechanisms.

20.	Johansson, Thomas B, et al. (author) Proton-Induced X-ray Emission Spectroscopy in Elemental Trace Analysis 1972 In: Advances in X-Ray Analysis. - Boston, MA : Springer US. ; 15, s. 373-387 Journal article (peer-reviewed)abstract Using protons in the MeV range as excitation source and a high resolution Si(Li) detector,X-ray emission spectroscopy is shown to be capable of analyzing many elements with Z > 15 simultaneously at the 10-12 g level. This work discusses a theoretical lower limit of detection at moderate proton energies and gives examples of possible applications: analysis of the elemental composition of air-borne particles as a function of particle size, oil slick identification, and analysis of water and blood serum.
