Detailed particle size distribution of elemental constituents have been determined in the St. Louis aerosol by sampling with cascade impactors for particles >0.25 μm aerodynamic diameter and by analyzing using proton-induced X-ray emission, PIXE, for S, Cl, K, Ca, Ti, Mn, Fe, Zn, Br, and Pb. Two rooftop sites were selected for intensive sampling in industrial and residential locations in St. Louis
As embedded systems become more and more complex, and the time to market becomes shorter, there is a need in the embedded systems community to find better programming languages that let the programmers develop correct code faster. The programming languages used today, typically C and/or Assemblers, are just too error-prone. The Java technology has therefore gained a lot of interest from developers
There are many possible definitions of “technology” and I will discuss some of these in this book. However, in this introduction let me use a definition of Svante Lindqvist who defines technology very intuitively as “those activities, directed towards the satisfaction of human wants, which produce change in the material world.” He says also “the distinction between human “wants” and more limited h
Under livets utveckling på jorden har solljuset med sitt karakteristiska spektrum och sin dygnsvariation haft en avgörande betydelse, t ex att vi har olika hudfärg, att vi blir solbrända, att vi har en 24-timmars dygnsrytm. Detta behandlas under rubrikerna Solljusets inverkan på huden; Årstidsrelaterad nedstämdhet; Skiftarbete och arbete under jord; Belysningsplanering för bättre hälsa; Färgsättni
Cellulose is one of the most abundant biopolymers on earth. Several organisms degrade cellulose, one of the most studied is the fungus Trichoderma reesei which produces seven genetically different cellulases. In this thesis, a thorough study of the hydrolytic characteristics of the less studied endoglucanases Cel12A (EG III), Cel45A (EG V) and Cel61A (EG IV) of T. reesei is presented
Asymptotic iterative decoding performance of low-density parity-check (LDPC) convolutional codes is analyzed. An important role within the analysis is a theorem on the minimal length of cycles in the Tanner graph describing a code
Alla stövsländearter som påträffats i Norden beskrivs med utförliga texter, pedagogiska illustrationer och de flesta med utbredningskarta. Nycklar för artbestämning gör det roligt och möjligt att ta reda på vilka arter man hittat. Volymen omfattar 82 nordiska arter varav 73 är funna i Sverige. Här följs den traditionella systematiska indelningen av stövsländor och därför inkluderas inte djurlössen
How much is democracy dependent upon supportive economic and social conditions? This question, which has occupied political scientists and sociologists for almost half a century, has attracted special attention in the last ten years as more and more countries have engaged in efforts to democratise. This volume is the first collection to take stock of current literature and put it into context. Thi
Kapitel belyser en särskild aspekt av handledningsverksamhet, de överenskommelser som görs mellan handledare och handledda och beskriver hur dessa handledningsöverenskommelser kan konstrueras som kontrakt mellan antingen rationella agenter, diskursiva kommunikationssystem eller moraliska subjekt. Det pekar på konsekvenser detta medför för utveckling av handledningskompetens. Handledning i pedagog
