Materials in particulate form for tissue engineering. 1 Basic concepts

For biomedical applications, materials small in size are growing in importance. In an era where ‘nano’ is the new trend, micro- and nano-materials are in the forefront of developments. Materials in the particulate form aim to designate systems with a reduced size, such as micro- and nanoparticles. These systems can be produced starting from a diversity of materials, of which polymers are the most used. Similarly, a multitude of methods are used to produce particulate systems, and both materials and methods are critically reviewed here. Among the varied applications that materials in the particulate form can have, drug delivery systems are probably the most prominent, as these have been in the forefront of interest for biomedical applications. The basic concepts pertaining to drug delivery are summarized, and the role of polymers as drug delivery systems conclude this review

OCULUS RIFTS PÅVERKAN PÅ IMMERSIONEN KRING MORALISKA VAL : En studie kring modern VR-teknologi och desspåverkan på en användares spatiala immersioni en virtuell miljö

This report is about VR and the effects the VR technology Oculus Rift may or may not have on the different kinds of immersion possible in virtual environments, or games. The report is based on the premise that modern games have evolved into more story based adventures with better graphics, often with moral choice as gameplay, and theories regarding new mediums and the dangers of not fully understanding them. It is also done in cooperation with a research team at Högskolan i Skövde, with a focus on moral dilemmas, and is using a virtual environment to test this combined effort. The game engine Unity is used to create a realistic environment and together with the Oculus Rift, is testing what kinds of effects the VR technology has on the users. 20 test participants have shared their experiences and the majority, independent of gaming experience, claims it has a positive effect

Vikingatida runbleck : Läsningar och tolkningar

Föreliggande avhandling syftar till att utveckla läsningen och tolkningen av inskrifterna på de i dagsläget 46 kända vikingatida runblecken. Målet är att ge en så tydlig bild som möjligt av inskriftsgenren vikingatida runbleck. I detta syfte har upprepade fältundersökningar av runblecken genomförts med stereomikroskop. På grundval av på så vis etablerade nya läsningar föreslås nya tolkningar till de mest problematiska ställena i de tidigare tolkade runblecksinskrifterna. Nya tolkningsförslag ges även för runblecksinskrifter som tidigare har ansetts vara olexikaliska. Utöver nya läsningar och tolkningar resulterar denna studie i en kartläggning av relationen mellan runblecksinskrifternas innehåll och form å den enda sidan och runbleckens fyndmiljöer och utseende å den andra.The aim of this dissertation is to represent as clearly as possible the genre of Viking-Age runic plates by developing readings and interpretations of the inscriptions on the 46 metal plates with runes from the Viking Age known today. Several investigations of the runic plates have been conducted with a stereomicroscope for this purpose. On the basis of the new readings thus established, new interpretations have been proposed for the most problematic sections of previously interpreted inscriptions. New interpretations are also offered for inscriptions on runic plates which have previously been considered non-lexical. As well as providing new readings and interpretations, this study has resulted in clarification of the relationship between the form and content of the inscriptions on the runic plates on the one hand and on their find circumstances and appearance on the other.

En nytolkning av Birka-amuletten

The aim of this paper is to provide a new reading and interpretation of the runic inscription on a silver capsule pendant from Birka which has been dated to the early Viking Age, 775–900 CE. It was found in a female grave and in the runological literature is conventionally known as the Birka amulet. The circum­stances of the find are first discussed in order to establish the exact location of the pendant in the grave. This is followed by a discussion of the possible identity of the woman in the grave and the possible location of the amulet on her body. As regards the function of the pendant, it has been determined that it was repurposed from another object in order to serve as a scent box and it was at that time that the runic inscription was carved on the reverse side. Earlier readings and interpretations are then discussed, followed by an analysis of the reading order of the inscription. A new reading based on three separate exami­nations with stereo microscope is subsequently suggested and illustrated with photo­graphs. To conclude, having established both reading order and reading, a new interpretation is suggested for the entire inscription.https://doi.org/10.33063/diva-438136</p

Attention guidance in horror games : Can lighting be used effectively as a player guiding technique through a game world?

Rapporten handlar om uppmärksamhetsstyrning inom skräckspel och huruvida olika ljussättningstekniker kan påverka spelarens navigation. Rapporten grundas i kognitionsvetenskapsteorier om visuell perception och olika typer av uppmärksamhet. Problemformuleringen är att moderna spel innehåller effektiva guidningsmetoder och dessa passar inte alltid i skräckspel då spelarens immersion lätt bryts med sådana metoder. Ljussättning är viktigt i skräckspel och rapporten har undersökt huruvida olika tekniker kan användas effektivt som substitut för mer traditionella guidningsmetoder. Spelmiljön är en sci-fi-miljö utan något statiskt gränssnitt. Miljön är skapad med UDK och innehåller åtta ljussättningstekniker/rum som spelaren går genom. 18 deltagare observerades och 34 deltagare gjorde en nätundersökning. Spelarbeteenden sammanställdes utefter resultatförväntningar kring ljussättningsteknikerna. Ingen grupp betedde sig helt som förväntat med stora procentskillnader mellan grupperna. Resultaten hamnade ofta kring 50 % eller lägre vilket tyder på att förväntningarna inte stämde överens med verkligheten. Framtida arbete kan handla om annorlunda konstruktioner av ljussättningsteknikerna samt undersöka vägvalsbeslut och höger-/vänsterhänthet

Korpuskatalog till Viking-Age Runic Plates: Readings and Interpretations

The present catalogue is in Swedish and it is a companion volume to Viking-Age Runic Plates. Reading and Interpretations. Te aim of this volume is to represent as clearly as possible readings of the inscriptionson the 46 metal plates with runes from the Viking Age known today. Several investigations of the runic plates have been conducted with a stereomicroscope for this purpose. The catalogue provides an argued documentation of these investigations
