Vid användandet av en skivbroms på ett tåg frigörs partiklar i friktionskontakten mellan skiva och belägg. Beroende på den aerodynamiska diametern blir partiklar luftburna, och de anses vara farliga för människans andningssystem. Att fånga upp partiklarna och på så vis förbättra luftkvaliteten är därför fördelaktigt.Olika metoder för uppsamling av de luftburna partiklarna utvärderades och den mest lämpliga valdes för vidareutveckling. En konceptuell lösning, för applicering av denna metod på en Reginaboggi, genererades och utformades.Resultatet är en partikelfångare som renar luft med hjälp av filter med tillräcklig uppsamlingseffektivitet. En central uppsamlingsenhet monteras på boggin, och ansluts med rörledningar till insug monterade vid bromsbeläggen.

The aim of this Masters thesis is to deepen the understanding of how society affects literary criticism by studying the reception of two Swedish dystopian novels and their contemporary anchorage. The questions that we answer here are concerned with how critics have drawn parallels between the novels and events occurring in the contemporary society, and how the critics outlook on the future are connected to ideas about the future in the novels. The first novel, Kallocain 1940 by Karin Boye has been interpreted as a critical statement directed towards totalitarian ideologies. The second novel, After the Flood 1982 by P C Jersild, has been seen as a warning against nuclear warfare. This qualitative study is based on 41 reviews from Swedish daily press.

Amyotrophic lateral sclerosis is one of the major neurodegenerative diseases, causing an ascending paralysis that usually kills the patient within a few years from disease onset. The motor neurons show aggregates of proteins which in approximately 20 % of cases of the familial form contain mutated SOD1 protein. Trehalose is a disaccharide which has been shown to reduce protein aggregation and increase viability in cell models and alleviate symptoms in animal models of several neurodegenerative diseases associated with protein aggregation. When given orally to the SOD1G93A mouse model of ALS, trehalose failed to slow down the disease progression, which has led to questions about the uptake and distribution of the molecule in this mouse strain. The aim of this study was to investigate whether significant levels of trehalose reach the central nervous system of the SOD1G93A mouse after oral administration. This was performed by a trehalose assay of the brain of trehalose treated animals. A glucose assay was optimised for use in small samples of brain lysate after the digestion of trehalose into glucose by trehalase, and the difference in glucose concentration before and after digestion represented the trehalose level.

Attack och farväl är ett historiografiskt arbete. I arbetet presenteras läsaren för grunderna till varför två till synes samstämmigt agerande individer kommer att skildras på högst olikartade vis.

Att eleverna i skolan ska utvecklas och nå de mål och kunskapskrav som finns skrivna i läroplanen är en central del i skolvärlden. Men hur når man då dessa på bästa sätt? Hur ska man som lärare veta vilken undervisning som är bäst för sina elever? I läroplanen står att eleverna ska ges en varierad undervisning där eleverna själva ska få gestalta, prova och utforska (Lgr11). Syftet med denna litteraturstudie är att undersöka om laborativa arbetsätt i matematik är gynnsamt för eleverna. I studien framställs att arbeta laborativt kan vara gynnsamt men till en viss del och att det beror på en del olika faktorer, som exempelvis lärarens roll och hur väl uppgiften och materialet framträder varandra..

The following essay aims at the interplay between regional och municipal growth work, and theway cultural heritage is used in growth work strategies.
