Vad är ett ord? Hur många ordklasser finns det egentligen? Finns det några begränsningar på vilka nybildningar som kan göras? Hur lär sig ett barn hur orden ser ut i det egna modersmålet? Ovanstående frågor är några av de som Ord försöker ge svar på. Boken är en modern ordbildningslära som kombinerar klassisk ordbildningsteori med de senaste rönen inom grammatisk forskning. Ett brett spektrum av

My thesis focuses on magnetic orientation in migratory birds, i.e. how they can perceive information from the Earth’s magnetic field and use it for orientation. To examine magnetoreception and the function of the light-dependent magnetic compass in birds, I performed behavioural orientation experiments with European robins, Erithacus rubecula, under different spectra and intensities of light. The

Colorectal cancer is one of our most common malignancies and the second leading cause of cancer death worldwide. About 1/3 of the tumors are located in the rectum. Treatment advances such as the introduction of the standardized surgical technique total mesorectal excision (TME), pre-operative radiotherapy, and adjuvant chemotherapy have reduced the previously high local recurrence rates and improv

The striatum is part of the telencephalon, the most anterior part of the vertebrate brain. From when it first can be identified, telencephalic morphology is highly complex and a wide range of mechanisms has been suggested to participate in its induction, patterning and neurogenesis. Sonic hedgehog (shh), a gene coding for a secreted protein has been suggested to be required for ventral telencephal

En diskussion kring hur satser av typen "(samma bil) som jag har" skall analyseras: de har ibland uppfattats som attributiva relativsatser men numera vanligen som adverbiella komparativsatser (till det attributiva "samma"). En undersökning av ett par lagtexter på forndanska - där det fanns en lexikal åtskillnad mellan relativt "er" och komparativt "sum" - ger stöd för detta senare, om än inte helt

Protein kinase C (PKC) is a serine/threonine kinase family with 10 identified isoforms. The contribution of PKC isoforms to cell growth and differentiation, with focus on neurite outgrowth, was investigated, using neuroblastoma and immortalised neural cells as model systems. In neuroblastoma cells one or several of the classical PKC isoforms are of importance for driving proliferation, protecting

This thesis covers 12 years of experience in treating patients with congenital capillary malformations, so called port wine stains (PWS). The wide variation in treatment response to laser therapy has developed a profound need for the development of objective devises to measure treatment outcome, so that the maximum effectiveness of therapy can be achieved without unnecessary treatments. The purpos

Abstract The electrophysiological properties of insulin-secreting b-cells, glucagon-releasing a-cells and somatostation-producing d-cells in intact mouse pancreatic islets were investigated using the perforated patch whole-cell technique. It is demonstrated that it is possible to functionally identify the different cell types in situ. The ?-cells have a cell capacitance of 7.4 pF and differ from
