Development of a polymer based neural probe - How to record intracortical neural activity while minimizing the tissue response.

Intracortical neural probes have in the last couple of years been developed from stiff single probes to stiff multi-electrode neural probes to flexible multi-electrode neural probes. One reason for the change in design is that more than one recording/stimulation electrode, as in the case with a single wire, is needed for more advanced studies. The stiff multi-electrode probes were fabricated using

A grey-box model for steam pressure dynamics in the drying section of a paper machine

In the drying section of a paper machine, steam heated cylinders are used to control the moisture of the produced paper. In previous work it has been shown that the dynamics from the steam valve to the steam pressure in the cylinder can be described by a linear second order black box process model. In this paper an equivalent model based on first principles is presented. The foundation of this mod

Kristendomens roll i en ny läroplan och ny lärarutbildning : Didaktiska och högskolepedagogiska perspektiv på undervisningen i religionskunskap

I samband med de nya läroplanerna i religionskunskap för grundskolan och gymnasiet har religionen kristendom kommit att fortsatt ha en särställning, trots att detta inte var inskrivet i Skolverkets förarbete. Kristendom är den enda religion som explicit skrivs ut i läroplanerna och därmed ställs specifika krav på lärare i religionskunskap. Undervisning om kristendom har alltid funnits med i läraru

Polyamine analogues inhibit neuroblastoma cell growth

Popular Abstract in Swedish Summary in Swedish Populärvetenskaplig sammanfattning Neuroblastom uppstår ur omogna nervceller i binjurarna eller i nervvävnaden bredvid ryggraden och är den vanligaste extrakraniala solida tumörformen hos barn. Varje år drabbas ca 10-15 barn i Sverige och sjukdomen uppkommer vanligast hos barn under 4 år. Trots enorma framgångar med behandlingsformer, så som cytostatAbstract Neuroblastoma is a highly malignant neoplasm found in children. Although children with high-risk neuroblastoma respond to chemotherapy, relapses are common and an estimated long-time survival prognosis is approximately 15%. Thus, there is a tremendous need for new chemotherapeutic drugs for the treatment for neuroblastoma. Polyamines are needed for cell proliferation and cell survival. Th
