(author) Pulp chemistry in calcite flotation. : Modelling of oleate adsorption using theoretical equilibrium calculations 1989 In: Mining engineering. - 0026-5187. ; 2:1, s. 93-109 Journal article (peer-reviewed)abstract This paper considers the conditions required for direct flotation of calcite. Flotation experiments have been performed with oleate as the collector reagent and water glass as the dispersant and modifier. To be able to explain what happens in the flotation, solubility and adsorption experiments have been conducted parallel to, and under the same conditions as, the flotation experiments. Theoretical equilibrium calculations have been made with the help of data from the practical experiments for the purpose of modelling the adsorption experiments. With theoretical equilibrium calculations it is possible to predict that silicate ions will form complexes with calcium ions at the mineral surface.
24.	Antti, Britt-Marie, et al. (author) Pulp chemistry in industrial mineral flotation. Studies of surface complex on calcite and apatite surfaces using FTIR spectroscopy 1989 In: Mining engineering. - : Elsevier BV. - 0026-5187. ; 2:2, s. 217-227 Journal article (peer-reviewed)abstract Flotation experiments in a Hallimond tube have been performed on calcite and apatite at pH levels and oleate concentrations judged to be interesting from the point of view of adsorption isotherms. For the calcite system, adsorption isotherms indicate precipitation of calcium oleate after monolayer formation at pH 9, 10 and 11. In the apatite system, a double layer of oleate is formed. This means that apatite, unlike calcite, is sensitive to collector reagent overdosage. With the aid of FTIR techniques it is possible to demonstrate the existence of a surface complex in the apatite system with a calcium-oleate ratio of 1:1 at monolayer coverage of the surface. In conditions corresponding to bulk precipitation of calcium oleate, this compound can be detected by FTIR analysis of unfloated material.

(author) Aberrant eating behavior in elderly parkinsonian patients with and without dementia : analysis of video-recorded meals 1989 In: Research in Nursing & Health. - : Wiley. - 0160-6891 .- 1098-240X. ; 12:1, s. 41-51 Journal article (peer-reviewed)abstract Aberrant eating behavior among 14 elderly, non-demented and 10 demented patients with Parkinson's disease was studied by means of video-recordings. The findings revealed problems in handling food on the plate, transporting food into the mouth, manipulating food in the mouth, and swallowing. Interpretations were performed based on impairments of autonomic processes, perception, cognition, emotion, and motor performance that occur in the disease.
