Popular Abstract in Swedish Ser man bakåt i historien har människan alltid försökt reparera eller ersätta vävnader i kroppen vid skador. En av de äldsta rapporterna om användande av biomaterial är runt 4000 år gammalt. I detta fall användes linnefibrer som suturmaterial. Från början användes naturliga material som collagen, silke, hår, bomull och olika cellulosamaterial. Under senare hälften av 19The aim of the this thesis was surface modification of a biomedical polyurethane (PUR), Pellethane 2363-80AE*, to improve the biocompatibility. Surfaces modified by poly(ethylene oxide) (PEO) were prepared either by grafting PEO covalently at the PUR surface by a two-step reaction, or by using amphiphilic polymers containing PEO as the hydrophilic part. The amphiphilic polymers consisted of one co

Preface to the new Swedish translation of Friedrich Engel's The Origin of the Family, Private Property, and the State.

Primary osteoporosis in children often leads to vertebral fractures, but it remains unknown whether these fractures associate with changes in bone composition. This study aimed to determine the differences in bone composition in fracture‐prone children with and without vertebral fractures, as assessed by Fourier transform infrared spectroscopic imaging (FTIRI) and bone histomorphometry. Iliac cres

The thesis considers the effects of electron correlation by studying the two opposite limits of atoms in the ground state and atoms in strong laser pulses. Computational methods and theoretical approaches differ significantly due to the different physical processes that are studied in these two cases. The thesis has an introductory chapter with a brief discussion of the problem of describing elec

This chapter describes various kinds of artificial light sources of interest to the photobiologist (natural light is described in separate chapters), starting with incandescent lamps and their properties, and continuing with gas discharge lamps, flashlamps and lasers. After a section on light filters the chapter concludes with a treatment of monochromators, in which the mode of action of a grating

Finger tapping to isochronous pacing stimuli is a well established experimental paradigm first described in the late 19th century. Two variables of common interest in rhythmic tapping tasks are timing variability and constant error. However, a difficulty when estimating these variables is that at interstimulus intervals longer than 2 seconds participants regularly overshoot the target interval and

Popular Abstract in Swedish Växternas respirationskedja innehåller protonpumpande enzymer, som konserverar energi i form av en protongradient, samt alternativa icke-protonpumpande enzymer. I det mitokondriella innermembranet finns ett protonpumpande NADH dehydrogenas, komplex I, och alternativa typ II NAD(P)H dehydrogenaser som kan oxidera NADH och NADPH från matrixen eller cytosolen. I ArabidopsiThe respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. The seven gene homologues of typ
