Twenty-four adult patients who had been operated on as infants for isolated cleft lip underwent clinical examination combined with photographic documentation using a digital camera. The same predetermined protocol comprising 20 variables describing nasolabial appearance was used for both the clinical examination and the computerised evaluation of the images. The correlation between the two methods

The purpose of this study was to evaluate the effect of dose reduction in digital mammography on the detection of two lesion types-malignant masses and clusters of microcalcifications. Two free-response observer studies were performed-one for each lesion type. Ninety screening images were retrospectively selected; each image was originally acquired under automatic exposure conditions, correspondin

The first late-glacial lake sediments found in Greenland were analyzed with respect to a variety of environmental variables. The analyzed sequence covers the time span between 14400 and 10500 calendar yr B.P., and the data imply that the conditions in southernmost Greenland during the Younger Dryas stadial, 12800-11550 calendar yr B.P., were characterized by an arid climate with cold winters and m

The J = 0 --> J' = 0 radiative transitions, usually viewed as allowed through two-photon decay, may also be induced by the hyperfine (HPF) interaction in atoms or ions having a nonzero nuclear spin. We compute new and review existing decay rates for the nsnp P-3(J)0 --> nS(2 1)S(J'= 0) transitions in ions of the Be (n = 2) and Mg (n = 3) isoelectronic sequences. The HPF induced decay rates for the

Ur ett hundraårsperspektiv har arbetsmarknaden genomgått avsevärda förändringar. Majoriteten av löntagarna utgörs numera av tjänstemän. I Sverige svarar de även för majoriteten av fackmedlemmarna. De svenska fackföreningarna tillämpade redan tidigt en bred medlemsrekrytering, men till bilden hör också att Sverige har världens mest klassuppdelade fackliga rörelse. Inte minst för tjänstemännen har d

It has recently been recognized that there is declining interest in ornithology among the younger generations. In this paper we analyse the short and long-term dynamics of the Swedish Ornithological Society (SOF) and the Swedish Society for Nature Conservation (SNF) by using analytical tools from population ecology. We first show that the increasing number of SOF and SNF members is not the result

This report contains abstracts of master thesis (examensarbete) made at the Department of Automatic Control, Lund, during the academic year 77/78. During this year 16 theses were made by 23 students. The theses are written in Swedish with an English abstract.

Radiative lifetimes of 6 levels belonging to the4f⁵(⁶H^deg,⁶F^deg)5d configuration of Sm III have beenmeasured for the first time using a time-resolved laser-inducedfluorescence technique. Experimental data have been compared withsemi-empirical calculations. The agreement is excellent for 4 levelswith ⁶F^deg as a parent term

The neuroprotective effect of the antiparkinsonian monoamine oxidase (MAO)-B inhibitor, R-(-)-deprenyl has been under investigation for years. Cytoskeleton, a main component of cell adhesion, is involved in the development of R-(-)-deprenyl-responsive diseases, the effect of the drug on cell adhesion, however, is not known. We examined the effect of R-(-)-deprenyl on cell-cell adhesion of neuronal

1. The impact of the introduced omnivorous signal crayfish (Pacifastacus leniusculus ) on trout fry, macroinvertebrates and algae was evaluated in a brown water stream in southern Sweden using in situ enclosures. We also examined the gut content of all surviving crayfish in the enclosures. Two crayfish densities in addition to a control without crayfish were used in replicate enclosures (1.26 m(2)

Fourteen patients with spinal lymphoma examined by MR imaging were reviewed. Thirteen of them also had extraspinal lymphoma. Vertebral involvement was found in 12 patients, epidural in 10, and paraspinal in 8 patients. On the basis of MR imaging at 0.3 T, spinal lymphoma may be divided into three types of growth pattern according to the main location: paraspinal, vertebral, and epidural. Most freq

High nutrient availability and defoliation generally reduce ectomycorrhizal colonization levels in trees, but it is not known how this affects the functional aspects of mycorrhizal symbiosis. It was therefore investigated whether (1) defoliation or increasing substrate N availability reduce C allocation from the plant to the fungus and N allocation from the fungus to the plant (symbiotic resource
