Popular Abstract in Swedish Stjärnhimlen har genom tiderna fascinerat människan och man har under historiens gång upprepade gånger försökt förklara vad stjärnorna består av samt hur de skapats. Många av dessa förklaringar har varit fantasifulla, men så här i efterhand sett ganska orealistiska. Till exempel var den medeltida bilden av stjärnhimlen att denna utgjordes av en sfär som roterade kring jThe relationship between the HgMn and Am classes of chemically peculiar stars has been investigated primarily by observing abundances of heavy elements, including Pr, Nd, Hg, Tl and Bi. The main objective of the investigation has been to gather observational evidence to provide a better understanding of the mechanisms producing the abundance anomalies of these stars, and to establish the relations

Det här kapitlet diskuterar och analyserar digitaliseringen av det vetenskapliga publiceringssystemet, framförallt i relation till peer review-processen och Open Access (OA). I vilken utsträckning är exempelvis tillit till vetenskaplig forskning, uttryckt i publikationer, rättfärdigat och hur kan den bedömas? Kapitlet använder sig av exemplet där vetenskapsjournalisten John Bohannon avslöjade bris

Some colours might have different connotations depending on people’s cultural backgrounds. When talking about evacuation, the colour employed for exit signs and flashing lights plays a significant role because it is responsible for conveying a message to the evacuees, either danger or safety. The aims of this study are to evaluate the influence of red and green emergency way-finding systems on the

The chapter is a discussion of the limitations and possibilities of digital film archives with reference to the specific needs of experimental film culture. Some films by filmmakers Reinhold Holtermann and Hans Nordenström are discussed in the framwork of the Swedish digital film archive "filmarkivet.se".

Popular Abstract in Swedish Den mänskliga arvsmassan består bara till en begränsad del av gener som kodar för proteiner som används för livsnödvändiga funktioner. Så mycket som 50 % eller mer består av repetitiva sekvenser, dvs sådana DNA element som finns i 100-100.000-tals mer eller mindre identiska kopior. Man kan säga att dessa är genetiska parasiter som använder sig av den mänskliga cellens eHuman endogenous retroviruses (HERVs) are remains of ancient retroviral infections of the germ line and constitute as much as 3 % of the human genome. HERVs are genetic elements that potentially may provide important biological functions by several different mechanisms. The ability to transpose long after the initial insertion into the germ line may provide a potent source of insertional mutagenes

Phosphonated polymers may show high intrinsic proton conductivities at low water contents provided that the local concentration of phosphonic acid groups is very high [1,2]. Moreover, the lower acidity of aryl- and alkylphosphonic acids in relation to sulfonic acids requires higher acid contents to reach high conductivities also at higher water contents. In this context, poly(vinylphosphonic acid)

This report is part of the National evaluation of the Swedish compulsory school. The evaluation was conducted by the National Board of Education in 2003. The present report deals with pupils' attitudes to History as a subject and to history education in the 9th grade. We have also made an evaluation of pupils' knowledge of history. The survey shows that a majority of the pupils have positive views
