- Cholesteryl sodium sulphate (CS) crystallizes as the dihydrate, the crystal structure of which is known. On heating the dihydrate, solid state phase transitions are observed at 65 degrees C and 95 degrees C and melting occurs at 165 degrees C. The structure of the high temperature phase has not been determined. Cholesteryl dihydrogen phosphate (CP) is not isostructural with any phases of CS. It undergoes a phase transition at 50 degrees C and melts at 190 degrees C. In systems with water CS is unstable whereas it was possible to determine the phase diagram of CP. In most of the composition range a crystalline hydrate is in equilibrium with a gel-phase. The latter has remarkable properties in that lamellar order exists with the 46 A lipid bilayer interleaved with water layers up to 1000 A. The monofilm behaviour of CS and CP at different pH levels is also reported.

Effects of amount of contact between mother and child on the mother's nursing behavior.
- 1978

In: Developmental psychobiology. - : Wiley. - 0012-1630. ; 11:2, s. 143-50

Journal article (peer-reviewed)abstract
- Short-term effects of different amounts of body contact between mother and newborn on human nursing behavior were studied. Extended contact immediately after parturition was related to an increase in affective components of maternal nursing behavior observed on postpartum Days 2 and 4.

The incidence of diabetes mellitus in Swedish children 1970--1975.
- 1978

In: Acta paediatrica Scandinavica. - 0001-656X. ; 67:2, s. 139-43

Journal article (peer-reviewed)abstract
- We report a retrospective study of diabetic children, 0--14 years of age, from seven Swedish departments of paediatrics. There were 359 new cases in the years 1970--1975. Notification suggested that there was a mean yearly incidence of 19.6 cases per 100 000 with a year to year variation of 10.0--26.4 per 100 000. Consequently about 330 new cases of childhood diabetes would be expected in Sweden every year. Incidence varied considerably between different geographical areas. The age distribution was bimodal with a main peak at about 12 years and another peak at about 7 years. There was some evidence for clustering of new cases in January and the autumn. The mean prevalence of childhood diabetes in the seven districts was 1.3 per 1 000.
