The aim of this thesis was to reveal details of the interspecific hybridization among bryophytes as exemplified by Sphagnum capillifolium and S. quinquefarium. I used a combination of morphometric and molecular methods, and cultivation experiments to (1) identify hybrid gametophytes, (2) reveal the contribution of each of the parents to the genomes of hybrids, (3) study the fertility of primary hy
Popular Abstract in Swedish Retrovirus är en stor grupp av virus som infekterar djur och människor och kan ge upphov till olika slags sjukdomar. Hos människa finns tre olika grupper av retrovirus. Det mest kända är HIV (humant immunbrist virus) och infektion av detta leder i många fall till AIDS. Andra mänskliga retrovirus är HTLV, humant T-cells leukemi virus, och humant spumavirus. Förutom dessaEndogenous retroviruses (ERVs) are believed to be remains of germ-line infections that have become fixed in the population. They are involved in pathophysiological conditions, in mechanisms leading to infection protection, and directly in the physiology of the organism by participating in the regulation of cellular gene expression. It has been estimated that human ERVs (HERVs) make up about 0.6% o
Abstract in UndeterminedIn today's technology generations, e.g. 90 and 65 nm, the static power consumption becomes a major contributor to the total power consumption. This paper focuses on the arithmetic level and shows a methodology for a substantial reduction of the static power consumption. Simulations are done in a typical 130 nm technology. Based on the simulation results, the static power in

Popular Abstract in Swedish Avhandlingen diskuterar den sakramentala kyrkosynen hos den franske, romersk-katolske, teologen Henri de Lubac (1896-1991). Utgångpunkt är hans formulering (i ?Catholicisme? 1938): ?Om Kristus är Guds Sakrament, så är Kyrkan för oss Kristi sakrament. Hon (kyrkan) re-presenterar honom (Kristus), med detta ords hela urgamla kraft: hon gör honom i sanning närvarande.? ForThe thesis provides a discussion of the ecclesiology of the French Roman-Catholic theologian Henri de Lubac SJ (1896-1991) by showing how this is determined by his method of fundamental theology. I establish the term ?fundamental ecclesiology? for this inter-dependance of form and content, subject and object in theology; this is why his ecclesiology is sacramental in structure. I primarily use tex
The impact of the quantization of SNR measurements on the throughput of a multiuser diversity scheme for constant-rate transmission is investigated under a block-Rayleigh fading assumption. In the downlink, each user measures its SNR, quantizes it, and feeds it back to the transmitter, which transmits a packet to the user with the highest quantized SNR. In the case of several users having the same
Popular Abstract in Swedish HIV-2 isolerades första gången 1986, fem år efter att de första fallen av AIDS (orsakade av HIV-1) hade upptäckts i USA. Undersökningar har visat att HIV-2-infekterade individer också kan utveckla AIDS på samma sätt som HIV-1-infekterade personer, men smittsamheten är lägre och inkubationstiden från smitta till symtom förefaller vara längre för HIV-2 jämfört med HIV-1. We have followed a cohort of police officers in Guinea-Bissau between 1990 and 1997 for the study of clinical, immunological and epidemiological aspects of HIV-2 infection. Initially the prevalence of HIV-2 was high (11.6 %) and HIV-1 infection was rare (0.4 %), but over the study period the prevalence of HIV-1 increased significantly whereas the incidence of HIV-1 was relatively stable. For HIV-2
Carton board packages are often closed with an adhesive. The adhesive joint thus formed has to meet the demands during the entire product life from converting to end-use. The adhesive joint has to be characterized if it is good or bad for the actual application. Today such characterization is done by manually peeling the joint, immediately after the adhesive application in the gluing machine. The
