Test av litiumheparinplasma fo?r analys av folat med Siemens Advia Centaur® XP samt effekt av inomhusbelysning o?ver tid

Background: Folate is a water - soluble vitamin necessary for normal DNA synthesis among  other mechanisms. Folate deficiency can cause megaloblastic anemia resulting from abnormal erythrocyte d evelopment. At the Department of Clinical Chemistry, Linköping, analysis of folate is performed with Siemens ADVIA Centaur® XP which uses an immunochemical method with chemiluminimetric detection. Currently, the assay is conducted on serum, is poured off and frozen after 48 h and treated with light protection because folate is considered to be light sensitive.Methods: This study tested lithium heparin plasma for analysis of folate with Siemens ADVIA Centaur® XP with the aim to be able to perform a package of analyzes in anemia investigation from the same collection tube. Furthermore, the stability of folate was studied for up to 168 h and examined regarding light sensitivity.Results: Statistically significant higher values were obtained in the analysis of folate in lithium heparin plasma than folate in serum (p < 0,001).

Kontext, utvärdering och användarupplevelse : En studie om kontextens påverkan på användarnas respons vid utvärdering av användarupplevelse

In this paper we explore the relations between context and feedback generated in three user-centered evaluations of a flash-based game. Whether it?s the social context, the physical context or the degree of intrusion from the evaluator, they all contribute to the quality of the feedback received. The selection of test subjects is a narrow process, which gives the above mentioned factors different meaning. Contextual factors have shown to influence the feedback given within both usability and user-experience.

Simulering av filtrerade skärmfärger

This report present a working model for simulation of what happens to colors displayed on screens when they are observed through optical filters. The results of the model can be used to visually, on one screen, simulate another screen with an applied optical filter. The model can also produce CIE color difference values for the simulated screen colors. The model is data driven and requires spectral measurements for at least the screen to be simulated and the physical filters that will be used. The model is divided into three separate modules or steps where each of the modules can be easily replaced by alternative implementations or solutions.

Bloggen - socialt medium med makt potential : En kvalitativ studie om konsumtionsideal bland svenska och internationella bloggar

Today, we live in a consumption society. We buy products to soothe our needs and desires.

With dialogical analysis and semiotic analysis we wanted to see if we could find a specific consumption culture in the content of six blogs we did our studies on. We found that the blogs showed us that there is normal to have everyday luxury and spoil oneself with expensive things.
