The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

The aim of this essay is to study and show the contents of the music repertoire that is used in live action role plays in Sweden and study how this repertoire is spread between participants in the culture of live action role playing.Four informants have been chosen and interviewed, three men and one woman of different ages from different places in Sweden.

BakgrundStamcellsforskning har utvecklats de senaste årtiondena och är idag ett behandlingalternativ, för flertalet sjukdomar. Stamceller är ursprungsceller för alla typer av blodceller och vid transplantation används stamceller tagna från benmärg, navelsträngsblod och/eller perifert blod. Transplantationen kan antingen ske autologt, där personens egna stamceller används, eller allogent, där stamcellerna härstammar från en donator. Om kroppen avstöter de donerade stamcellerna sker en immunologisk reaktion kallad graft-versus-host disease.I samband med transplantationen genomgår personerna i regel cytostatikabehandling med eller utan kroppsbestrålning, vilket kan medföra negativa följder som bland annat påverkar personens förmåga att inta oral nutrition. För en sjuksköterska är det viktigt att uppmärksamma och lindra en persons sjukdomsupplevelse samt motverka komplikationer.

The purpose of this paper is to find more understanding for pupils in compensatory educational situations and get an idea about how they place themselves in the social hierarchy. In my study I have interviewed four pupils with different experiences from school with the common denominator of being placed in a special class during some hours of the week. The purpose of this placement is to get them to achieve better results in various subjects depending on their grade but this also means a social separation from friends in the ordinary class and this doesn't correspond well with the democratic idea of "one school for all".What I found was that these pupils categorize themselves different from each other and while two of the pupils find themselves very included in the school's social network the remaining two had problems functioning satisfactory in a social matter according to their own liking. The feeling of exclusion though can not be connected to their participation in the special class but rather to their earlier social experiences..

Vårt syfte med examensarbetet har varit att undersöka hur förskollärare och föräldrar arbetar med barnlitteratur och högläsning i förskola och hem. Vi intervjuade därför fyra förskollärare samt lät föräldrarna till de barn som går på intervjupersonernas avdelningar fylla i en enkät. För att få kunskap om varför och hur man kan arbeta med barnlitteratur och högläsning använde vi oss av litteraturundersökning. Genom vårt intervjumaterial fann vi att förskollärarna arbetar med barnlitteratur och högläsning i olika grad och med olika metoder. Alla föräldrar i vår enkätundersökning läser högt för sina barn.
