As average packet sizes in wireless networks shrink and data rates increase, the fundamental CSMA mechanism in the 802.11 protocol family is put under stress. With the emerg- ing 802.11ax standard, the carrier sensing mechanism is low- ering the efficiency of the protocol to the level of random access (ALOHA), and as future-generation 802.11 standards emerge, CSMA-based protocols will fall below t
Popular Abstract in Swedish Ledgångsreumatism (reumatoid artrit) är en allvarlig inflammatorisk led- och systemsjukdom som drabbar ungefär 1% av befolkningen. Den är sannolikt den vanligaste behandlingsbara orsaken till invaliditet i västerlandet. Under de senaste 10 åren har allt fler forskare uppmärksammat sjukdomens dåliga prognos och manat till en tidigare och mera effektiv behandling så snartRheumatoid arthritis (RA) is probably the most common source of treatable disability in the Western world. There are several disease-modifying antirheumatic drugs (DMARDs), which have proven to be of therapeutic efficacy in RA, but the lack of a potent, reliable treatment for early RA is a major problem in modern medicine. An obvious line of approach in the quest for better antirheumatic drugs is
This paper attempts to address the failings of a predominant paradigm in IS research and practice that emphasises technological determinism. This paradigm makes use of a false belief in the power of rationality in organizational decision-making, and a mythology in which organizational actors can be viewed as passive ‘users’ of technology. We wish to create a discussion of the nature and role of pr
The optical design for the proposed Euro50 extremely large telescopewith integrated adaptive optics (AO) is presented. For atmosphericturbulence correction, we propose using single and dual-conjugate AOsystems working with natural and laser guide stars. The corrective shapeof the deformable mirrors (DMs) is derived from an analytical algorithmbased on minimization of the sum of the residual power

While contemporary international law is often understood as teleological, encompassing notions such as progress, development, and prosperity for all of human kind, in this essay the field of the international law of belligerent occupation is read as katechonic, as embodying the figure of the katechon within international law’s eschatology. The essay considers Carl Schmitt’s political theology thro
Popular AbstractStudien är ett försök att analysera den sociala konstruktionen av "medievåld" i den svenska pressdebatten 1980-1995. Totalt analyserades 1029 artiklar ur sju av Sveriges största dags- och kvällstidningar. Många artiklar refererar till vetenskapliga "bevis" att våld i medierna föder faktisk aggression. En närmare analys av medieeffektforskningen avslöjar dock att det påstådda sambanThis study is an attempt to analyze the social construction of media violence in the Swedish press debate 1980-1995. Altogether, 1029 articles from seven of Sweden's biggest daily and evening papers were qualitatively analyzed. Numerous claims refer to scientific 'proof' that media violence breeds personal aggression. However, a critical examination of the media effects research reveal that the al
Del 1, "Skandinaviske engagementer 1945–1967": I et internationalt avantgardelogisk perspektiv kan man betragte det tyvende århundredes kultur i forhold til to klynger af “begivenheder”, en klassisk heroisk (høj)modernisme i kunstarterne fra begyndelsen af århundredet og en begyndende postmodernisme i både kunst og teori fra ca. 1970, der begge først blev navngivet og kortlagt senere. Den nordisk
Highly sensitive biosensors were developed for environmental and medical applications. The biosensors were based on bioengineered proteins as biorecognition elements coupled to a highly sensitive capacitive transducer. Heavy metal binding proteins like the metallothionein SmtA, regulatory protein MerR, periplasmic protein MerP and the synthetic phytochelatin EC20 were used for designing, construc
Andra världskriget utgör den mest genomforskade perioden i svensk historia. Med några få undantag har emellertid hittillsvarande undersökningar undvikit en av de viktigaste ingångarna till en djupare förståelse för dessa unika år – bilderna. Med Sveriges statligt sanktionerade bildpropaganda i fokus studerar denna bok hur nationens frihet och oberoende konsoliderades visuellt perioden 1939–1945. I
