Experimental Neuroretinal Transplantation

Embryonic full-thickness rabbit neuroretinal sheets were transplanted to the subretinal space of adult hosts. This was accomplished by using a new transplantation technique involving vitrectomy and retinotomy. The grafts were followed from 10 to 306 days after surgery, and were then examined by different histological techniques. In the light microscope, the transplants were seen to develop the nor

Language and Literacy : Some fundamental issues in research on reading and writing

Abstract in Norwegian Hovudlina i forskinga på lesing og skriving byggjer på tanken om at talt språk på alle vesentlege punkt er primært i høve til skrive språk. Omgrepsapparatet for studiet av språk og lese- og skrivedugleik er også bygd kring denne tanken. Dette er problematisk frå eit vitskapsteoretisk standpunkt sidan tanken om det talte språket sin dominans ikkje er tilstrekkeleg empirisk undMainstream research on reading and writing is based on the assumption, common in modern linguistics, that spoken language is primary to written language in most important respects. Unfortunately, the conceptual framework for the study of language and 'literacy' (encompassing both reading and writing skills) is built around this assumption. This is problematic with regard to the philosophy of scien

Real-time real-sky dual-conjugate adaptive optics experiment

The current status of a real-time real-sky dual-conjugate adaptive optics experiment is presented. This experiment is a follow-up on a lab experiment at Lund Observatory that demonstrated dual-conjugate adaptive optics on a static atmosphere. The setup is to be placed at Lund Observatory. This means that the setup will be available 24h a day and does not have to share time with other instruments.
