Popular Abstract in Swedish Cytokrom P450 är en grupp enzymer som introducerar alkoholgrupper i främst icke-vattenlösliga ämnen. Alkoholgupperna gör dessa föreningar mer vattenlösliga och känsliga för fortsatta reaktioner. Cytokrom P450-enzymer återfinns i de tre domäner allt levande kan indelas i: eukaryoter (djur, växter, svampar, protozoer m.m.), bakterier och arkeér (ett slags bakterier som skCytochromes P450 constitute a super-family of heme containing mixed function mono-oxygenases that is found in all branches of life. They introduce single oxygen atoms, mostly in the form of hydroxyl groups, into lipophilic substances and thereby render them more hydrophilic and susceptible to further reactions. Little is known about the bacterial cytochromes P450. I have in my thesis given an over

Nearfield Radar Cross Section (RCS) measurements and Inverse Synthetic Aperture Radar (ISAR) processing are used in this study to obtain geometrically correct images and farfield RCS. The back projection algorithm is used to determine the amplitudes and locations for the scatterers in a point by point imaging process. Different approximations are used to sum the nearfield RCS recorded at an azimut

This article focuses on a theoretical evaluation of a hybrid excited synchronous machine where the excitation circuit is a combination of electrically magnetized (EM) and permanent magnetized (PM) magnet poles in the rotor. This alternating pole configuration of electrically magnetized (EM) or permanent magnet (PM) poles determines the hybrid magnetization. The target of the analysis is a traction

Sustainable development and engineering ethics as well as social aspects of engineering are emerging issues related to power electronics. Several important topics like environmentally sustainable products and electromagnetic compatibility fit into this description. Therefore, these issues have recently become part of the advanced course on power electronics at Lund University. The authors' intenti

The lichenized ascomycete genus Xanthoria (Fr.) Th.Fr. (Teloschistaceae) in continental United States and Canada is revised. The following 15 species are recognized: Xanthoria borealis, X. candelaria, X. concinna, X. elegans, X. fallax, X. fulva, X. hasseana, X. mendozae, X. montana, X. oregana, X. parietina, X. polycarpa, X. sorediata, X. tenax, and X. ulophyllodes.
