We screened 150 olfactory sensilla in single-sensillum recordings to unravel the mechanisms underlying host selection in the spruce bark beetle, Ips typographus (Coleoptera: Curculionidae: Scolytinae). Odor stimuli comprised of pheromone (various bark beetle spp.), host, and non-host compounds elicited strong and selective responses from 106 olfactory receptor neurons (ORNs), 45 of which were tune

Christian theology is in favour of interreligious dialogue without proselytism. At the same time, all religious institutions do seem to have a drive to convert those who are not already inside. Hence there is a tension. Redefine the terms seems insufficient to me. The question to deal with is rather when, how, and why is conversion allowed or even praised even though the character of dialogue with

Background: Psoriasis is one of the most frequent skin diseases world-wide. The disease impacts enormously on affected patients and poses a huge financial burden on health care providers. Several lines of evidence suggest that the nuclear hormone receptor peroxisome proliferator activator (PPAR) beta/delta, known to regulate epithelial differentiation and wound healing, contributes to psoriasis pa

Popular Abstract in Swedish Proteiner är nödvändiga beståndsdelar i en levande cell. Dels bygger de upp viktiga strukturer och dels katalyserar de kemiska reaktioner. Proteiner kodas av gener. Varje protein motsvaras av en gen. Vägen från gen till protein är densamma i alla organismer på jorden. Först transkriberas en gen till en molekyl kallad mRNA (budbärar-RNA, eng. messenger RNA). Detta mRNA aDegradation of mRNA is a controlled process which is as important for gene regulation as the synthesis of mRNA. This thesis focuses on mechanisms of mRNA stability and degradation in Bacillus subtilis, the model of Gram-positive bacteria. The aprE mRNA, encoding an exported protease named subtilisin, is extremely stable with a half-life of more than 25 minutes. Average mRNA half-lives in B. subtil

Popular Abstract in Swedish Deponeringsavgifterna för slam utgör en betydande och stadigt stigande andel av driftkostnaderna för de kommunala reningsverken runtom i landet, inom EU och i resten av världen. Kostnaderna uppstår i samband med att slammet komposteras, körs till deponi eller till förbränning. Dessutom har det under de gångna årtiondena skett en drastisk omvärdering av reningsverksslam The reduction of sludge volumes for disposal is a topic of high interest for wastewater treatment plants (WWTP) all over the world. Steadily increasing volumes for disposal create an economic, environmental, legislative and technological challenge. Researchers and process developers try to minimise the sludge during its genesis or in the downstream treatment. Due to rising costs and scarcity of fo

One of the goals pursued in the present research was to understand the nuclear phenomena (such as rotational bands, their backbending and termination, deformation, pairing correlations, etc.) using different views provided by different nuclear models. The employed models complement each other: spherical shell model provided the laboratory frame description, the intrinsic frame description was prov

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Vår arvsmassa består av tre olika typer av DNA; kodande, reglerande och ofunktionellt DNA. Det kodande DNA:t används som ritning för hur våra proteiner ska sättas ihop. Proteinerna är de stenar som bygger upp våra celler och ger dem dess specifika funktion, en hudcell är t ex uppbyggd av andra proteiner än en muskelcell. Det är viktigtThe neutrophil store its effector proteins in several distinct types of cytoplasmic granules, developed sequentially during cell maturation. The different subtypes of granules have unique protein content and functional characteristics. The formation of each granule subtype coincides with the biosynthesis of its content. Granule proteins synthesised during the formation of a granule subtype are thu

Against the deeply ingrained belief that technology is instrumental and neutral, this thesis argues that our relation to technology is inextricably bound up with fantasies. But what is the nature of these fantasies and where do we find them? Are they strictly reserved to the domain of Science Fiction, or can we also find them in more mundane contexts, like the business organization? These are som

After four years of queuing on the Swedish list for transplant kidneys, Sam was tired of waiting – he went to Pakistan and bought a new kidney. But where did the new kidney come from? And was the donation of the organ he received really voluntary? In this book, Susanne Lundin explores the murky world of organ trade, where desperate patients like Sam are small pieces in a big puzzle. In her ethnogr

As a form of reflectivist critique of the scientific approach to the study of social sciences, constructivism was initially developed as a mostly interpretive metatheory. Its substantial and wide-ranging influence perhaps derives from the fact that what it says seems to be just common sense. Its insights apply to our individual experiences in life; as individuals our identities change over time an

Industry participation in teaching is often appreciated and inquired for by many students as it connects theory of academia with the reality of practitioners in industry. However, the industry involvement is often delimited to occasional guest lecturers or study visits and as such, it supplements the traditional, academic, teaching activities. The course, which is the subject of this paper, provid

Brenner hade tidigt blivit berömd för sin lärdom och sin diktning på fem språk, svenska, tyska, latin, franska och italienska. Redan samtiden (t. ex. Magnus Gabriel Block) lade märke till att hon alltmer favoriserade svenskan. I artikeln analyseras Brenners val av språk och hennes inställning och betydelse i tidens livliga språkpolitiska debatt.
