Popular Abstract in Swedish Mikroorganismer finns runt omkring oss i miljön och mycket tyder på att de påverkar oss mer, och delvis på ett annat sätt, än vi tidigare trott. Vi vet alla att infektioner kan spridas genom inandning av luftburna patogena mikroorganismer. Men luftburna mikrober kan även ge andra sjukdomar. Det är t.ex välkänt att lantbrukare riskerar att drabbas av symptom i luftvägarnMicroorganisms are ubiquitous in indoor air and epidemiological data suggest that inhalation of microbes and/or their products adhered on air–borne dust particles can impair well–being and health. In the present thesis microbial volatile organic compounds (MVOCs) and cellular markers were studied by gas chromatography–mass spectrometry (GC/MS). By using solid phase microextraction (SPME) combined

Popular Abstract in Swedish På utsidan av insidan - slemmet i tarmen Kroppens slemhinnor, till exempel de i magsäcken och tarmen, täcks av ett slemlager. Slemmet skyddar cellerna i slemhinnan från skadliga ämnen och mikroorganismer genom att ‘fånga’ dem och därmed hindra dem från att nå fram till cellerna. Slemmet är uppbyggt av stora, trådlika och ’klistriga’ molekyler, så kallade muciner, som gHighly glycosylated glycoproteins – mucins – are the major constituents of the mucus layer and glycocalyx that cover mucosal surfaces. Twelve human mucin genes have been identified, and the mucins may be divided into those that are membraneassociated and those that are secreted. Among the latter, the oligomeric mucins are responsible for mucus formation. The various tissues have characteristic muc

In this thesis, a critical investigation is presented about the role of mechanical strain for the electron-transfer properties of the blue copper proteins. It has been found that the structure of a realistic model complex of the oxidised blue-copper active site, optimised in vacuum with the B3LYP method, has the same trigonal cupric geometry as in the protein. Thus, the protein does not strain the

Joint property units and joint facilities are an integral part of the Swedish cadastral system. They are a result of the 19th century land reforms, where the units guaranteed a common resource system (roads, mills, drainage systems etc.) for externalities of the individual property. Today, several of these joint property units are unused and constitute land of low value. Joint facilities exist wit

Software architecture is recognized as a critical factor for successful products, but few have studied how organizations decide on architectural changes. In this paper we study the topic through several case studies. The changes are in all cases changes to the quality attributes of the system, and follow the same general process. We find that architectural changes have aspects of both functional a

How do readers interact with net papers? Does the new medium influence our way of searching for news? Does net-paper reading differ from newspaper reading? 12 users were asked to read 2 net-papers at their own pace. The aim of the study was partly to analyse reading behaviour on the Internet, partly to understand some of the underlying rationale and motivation of the behaviour. To achieve this aim

Conversation of Lithuanian philosopher and writer Tomas Kavaliauskas with Niklas Bernsand and Andreas Johansson Heinö about Swedish identity, multiculturalism and historical memory. Text in Lithuanian.

Measurement results of an analog channel decoder in 65 nm CMOS are presented. We target ultra compact and low power applications with low to medium throughput requirements. The decoding core is designed for (7,5)(8) convolutional codes and takes 0.104 mm(2) on silicon. The degrading effects of analog imperfections are investigated and the presented results allow power, performance and throughput t
