Based on how the mushroom Lactarius vellereus converts an inactive precursor into the cytotoxic dialdehyde isovelleral (1) via a cyclic enol ether, as part of a binary chemical defense system that protects the fruit bodies against parasites, a synthetic way to obtain analogous dialdehydes masked in the same way has been developed. As isovelleral analogues (e.g. 2 and 3) possess extremely potent cy
We present the characterization results of a new high resolution negative electron beam resist mr-L 6000.1 XP. The resist can also be used as imprintable polymer in nanoimprint lithography with sub-100 nm resolution. The feature size achieved after e-beam exposure was about 50 nm with sensitivity of 2-4 μC/cm2. Studies of the resist properties as a function of chemical composition and d
Popular Abstract in Swedish Moderns rökning under graviditet och risk för medfödda missbildningar. Ungefär två procent av alla nyfödda föds med någon missbildning såpass allvarlig att den rapporteras till missbildningsregistret och/eller till det medicinska födelseregistret. Trots alla samhälleliga insatser för att minska rökningen (speciellt i samband med graviditet) så röker (1996) 16% av de grAbout two percent of Swedish newborn infants are born with a significant congenital malformations which is reported to the Swedish Registry of Congenital Malformations (RCM), and/or the Swedish Medical Birth Registry (MBR). In spite of persistent public health recommendations, about 16% of the Swedish pregnant women are smoking during pregnancy (1996). It is well known that maternal smoking during
Popular Abstract in Swedish På senare tid har ett stort antal receptorer för extracellulära nukleotider (P2 receptorer) klonats vilka förmedlar en mängd effekter i hjärtkärlsystemet: inotropa effekter på hjärtat, trombocytaggregation, blodtrycksreglering, frisättning av endoteliala faktorer och stimulering av glatt muskeltillväxt. Redan idag står det klart att P2-receptorer är fysiologiskt och patP2 receptors mediate the actions of the extracellular nucleotides ATP, ADP, UTP and UDP regulating several physiological responses including cardiac function, vascular tone, smooth muscle cell (SMC) proliferation, platelet aggregation, and the release of endothelial factors. The aim of the present study was to investigate the mRNA and protein expression of P2 receptors in human SMCs, endothelial c
Gift-for-sex (GFS) barters are a niche practice potentially representing the commodification of everyday dating practices. We inquire how GFS exchanges are practiced and understood in contemporary Russia. Second, we situate these in relation to contemporary economic culture. Our project provides answers in two steps based on online content. First, we identify GFS exchange practices within a major
Fantasy är en tvärmedial genre. Det innebär att det som är typiskt för fantasy-genren och dess ”outworldliness” (Mackay 2001), det vill säga karaktärer med magiska krafter, talande djur, andar och älvor, geografiskt hisnande sagovärldar inspirerade av historiska och litterära myter och legender – inte bara återfinns i böcker utan även i film, brädspel, LAJV/LARP (rollspel med kostymer där du själv

En genomgång av hur de grammatiska delarna av ordboksartiklar om prepositioner har behandlats terminologiskt i Svenska Akademiens grammatik (1893–).

This thesis is about the conceptualization of persistence of physical, middle-sized objects within the theoretical framework of the revisionary ‘B-theory’ of time. According to the B-theory, time does not flow, but is an extended and inherently directed fourth dimension along which the history of the universe is ‘laid out’ once and for all. It is a widespread view among philosophers that if we acc
