Konsten i nätverket lever sitt egna liv

Konst på internet för en undangömd tillvaro så länge som vi inte riktar blicken mot de mest framgångsrika objekten som lever i detta nya medium, nämligen spelen. Artikeln placerar in spel och visuella objekt i spel inom ramen för samtida offentlig konst.

Studies on the alpha-recoil implantation of 214Pb and 210Pb in glass surfaces,Implications for retrospective radon measurements

Popular Abstract in Swedish Glas kan användas för retrospektiva radon mätningar på grund av radondöttrars förmåga att implantera i glasets översta skikt. Mängden implanterad aktivitet blir lätt påverkad av en rad olika faktorer i den omgivande luften. Experimentella metoder har därför utvecklats för att bestämma djupfördelningen av alfarekyl-implanterat 210Po i glas. Detta göres genom gradvis etsnGlass sheets are often used in radon surveys to estimate retrospective radon concentrations, as radon progenies are embedded in the upper surface layer. The implanted activity is influenced by a variety of different environmental conditions. In this work, experimental methods based on etching to determine the depth distribution of recoil-implanted 210Po in glass from radon decay in air were develo

Earwitnesses: The effect of voice differences in identification accuracy and the realism in confidence judgments

Individual characteristic features in voice and speech are important in ear witness identification. A target-absent lineup with six foils was used to analyze the influence of voice and speech features on recognition. The participants’ response for two voice foils were particularly successful in the sense that they were most often rejected. These voice foils were characterized by the features’ arti

The Valuable Body

The development of organ transplantation technology is an extraordinary achievement that has saved the lives of many, but which also has created an endless need for body parts. In focus for this article is the trade in organs - especially organ trafficking in Moldova.

A novel method for rapid design and evaluation of photovoltaic concentrators

The electrical output of low concentration systems with standard pv cells is heavily impaired by non uniform irradiation distribution on the cells. In order to design new concentrators that improve the system efficiency by homogenizing the light, a new method of evaluation has been developed. It is based on simulations, and generates an estimated annual output. The method consists of three steps,
