Popular Abstract in Swedish Denna avhandling beskriver vissa funktionella syntetiska modeller av non-hem mononukleära järn oxygenas-enzymer. Sådana enzymer katalyserar ett brett spektrum av oxidationsreaktioner av biologisk relevans, som utnyttjar molekylärt syre. Dessa reaktioner utförs i regio- och stereoselektivt sätt och med hög verkningsgrad. Föreslås oxidationsreaktionerna ske via mellan högNon-heme mononuclear iron oxygenases catalyze a large number of oxidation reactions in biological systems. The reactions are often proposed to proceed via the intermediacy of high valent Fe(IV) oxo (ferryl) or, Fe(V) oxo (perferryl) intermediates. Therefore, in order to mimic the high valent Fe(IV) oxo chemistry as well as the catalytic processes exhibited by those enzymes, new functional model co

Worldwide, disasters and climate change pose a serious risk to sustainable urban development, resulting in escalating human and economic costs. Consequently, city authorities and other urban actors face the challenge of integrating risk reduction and adaptation strategies into their work, although related knowledge and expertise are still scarce. Cities, Disaster Risk and Adaptation explores ways

A lower bound on the free distance of LDPC convolutional codes defined by syndrome former matrices comprised of MtimesM permutation matrices is derived. We show that asymptotically, i.e., as Mrarrinfin, for almost all codes in the ensemble the free distance grows linearly with constraint length

An introduction to an anthology on Öresund region research.

Under senare år har religion kommit att återigen spela en framträdande roll i svensk och internationell kontext. Mer eller mindre dagligen konfronteras vi med frågor som relaterar till religion och mänskliga rättigheter. Detta ställer högre krav på kunskaper om och förhållningssätt till det som sker runt omkring oss. I den här antologin skriver svenska forskare om religion och mänskliga rättighet

A model catalyst system with a loading range between 1/4 to 10 theoretical layers of vanadium oxide on TiO2(B ) support was tried for selective ammoxidation and oxidation of toluene. In the case of ammoxidation, a peak in conversion rate per unit surface area was found for a catalyst with a coverage of about 2 theoretical layers, indicating a strong interaction between the catalyst and the otherwi

Enterprise resource planning (ERP) systems have originally been developed for large enterprises (LEs). However, market saturation, integration of supply chains and technology improvements have led to small and medium-sized enterprises (SMEs) have started adopting ERP systems. Though there is a focus shift from LEs to SMEs in the ERP market, most academic literature on ERP systems is based on findi

The ambitious goal of the upcoming IEEE 802.11ax (HEW) standard for wireless LANs (WLANs) to enhance throughput by four times (and beyond), compared with IEEE 802.11ac, demands a radical improvement of present medium access control (MAC) functionality. To this end, a promising paradigm would be a graceful migration towards new MAC protocols which incorporate higher certainty in their decisions. Ho
