Clinimetrics in rehabilitation medicine: current issues in developing and applying measurement instruments 1

Clinimetrics in rehabilitation medicine, i.e. the field of developing, evaluating and applying measurement instruments, has undergone considerable progress. Despite this progress, however, several issues remain. These include: (i) selection of an instrument out of the wide range available; (ii) using an instrument in a variety of diagnostic groups; (iii) using an instrument in individual patients, as opposed to a group of patients; and (iv) the use of instruments in clinical practice. This paper reviews these issues, as well as current attempts at resolving them. Illustrative examples are given. It is concluded that solutions seem to be available, but considerable research effort is required to make these a reality. Clinimetrics in rehabilitation medicine remains a field with challenging opportunities for researc

Bunnfaunaundersøkelser i Tvedestrandsfjorden

Rapporten bygger på prøvetaking i nov. 1983 og des. 1984. De dypere deler av Tvedestrandsfjorden ut til Sagesund viste en ekstremt utarmet fauna og til dels døde bunnområder. Stasjonen utenfor Sagesund hadde også et lavt artsmangfold. Situasjonen i fjorden er relatert til stagnerende dypvannmasser pga terskler, store deponier av sagflis samt utledning av urenset spillvann på grunt vann fra Tvedestrand b

Undersøkelser i Sørsalten og Kolvereidvågen i Nærøy kommune, Nord- Trøndelag. Resipientundersøkelse

Kolvereidvågen og Sørsalten er undersøkt m.h.p. forurensningssituasjonen og nødvendigheten av overføring av utslipp fra Sørsalten til Kolvereidvågen, eventuelt en samling av utslippene begge steder til ett felles utslipp utenfor Korsnesstrømmen. Det konkluderes med at utslippene kan samles til ett felles dyputslipp i Kolvereidvågen. Overføring av utslippet fra Sørsalten til Kolvereidvågen anses ikke påkrevd ut fra en økologisk vurdering av forurensningen i Sørsalten

Further evidence for closed, nonspherical aggregates in the cubic I(1) phase of lysolecithin and water

Measurements of time-resolved fluorescence quenching have been performed in the binary lauroyllysophosphatidylcholine (LaLPC)/water system. The aggregation numbers, N, are determined for the micellar solution phase (N(micelle) ≈ 80) and the cubic liquid crystalline I(1) phase (N(cub) ≈ 90) at 298-303 K. When a quencher is present, the fluorescence decays for the hexagonal phase of the LaLPC/water system and for the bicontinuous cubic phase of monooleoylglycerol/water system are nonexponential, as expected for phase structures having long-range continuous apolar regions. Nuclear magnetic resonance (NMR) measurements of the lipid translational diffusion conclusively show that the cubic I(1) phase consists of closed micelles. NMR spectra of (31)P obtained at 202.4 MHz of this cubic phase exhibit a characteristic line shape, which is compatible with a phase structure containing short nonspherical micelles. A comparison between electron spin resonance (ESR) spin-label spectra recorded for a micellar solution and the cubic phases of the LaLPC and monooleoylglycerol systems are also shown to support a structure of closed micelles in the cubic I(1) phase of the lysolecithin system
