Under de senaste tio åren har intresset för studier i internationell politik ökat kraftigt. Samtidigt har forskningsområdet breddats både avseende vad som studeras, exempelvis kapprustning, miljörörelser eller historisk utveckling, och hur det studeras. Perspektiv på världspolitik tar fasta på dessa förändringar och betonar ämnets bredd samt ger en nyanserad och djuplodande presentation av såväl

A new approach to negative feedback is proposed and applied to active mixer cells based on Gilbert multiplier. The feedback can be exploited in several ways, and different configurations are derived. A dual-loop topology provides a solution for inductor-less broad-band receiver stages. The nature of the dual loop ensures controlled gain and input matching, and a first-order linearity analysis is p

Abstract in Undetermined Women and feminists about disktinktionen between women's theater and feminist theater.

Human cystatin C is a cysteine proteinase inhibitor belonging to the cystatin superfamily, which previously has been shown to inhibit bone resorption in bone organ culture. The aminoterminal segment, Arg8-Leu9-Val10-Gly11 (RLVG), of the single polypeptide chain of cystatin C constitutes an essential part of its inhibitory center. In the present study, the effect of benzyloxycarbonyl-Arg8-Leu9-Val1

Video-on-Demand (VoD) and video sharing services account for a large percentage of the total downstream Internet traffic. In order to provide a better understanding of the load on these services, we analyze and model a workload trace from a VoD service provided by a major Swedish TV broadcaster. The trace contains over half a million requests generated by more than 20000 unique users. Among other

Popular Abstract in Swedish En växt är under hela sin livstid utsatt för angrepp från organismer som helt eller delvis försöker äta den. Allt växtmaterial äts faktiskt upp förr eller senare. När växten är död ser nedbrytare till att inget av det kol som växten under sin livstid tagit upp från luften går till spillo. En intressant ekologisk fråga är varför vår värld (i allmänhet) är grön när det fiThis thesis discusses aspects of feeding habits of moose (Alces alces) and their impact on forest development. The development of forage that is available to moose was studied by sampling the amount of edible biomass on pine and birch trees. A strong relationship was found between foliage (and twig) biomass and tree diameter, which corroborates the hypothesis that sapwood area limits the amount of

Bound to Be Modern is the most comprehensive study to date on the emergence and function of publishers' cloth bindings. It brings together issues of aesthetics, technique, economy, and social change in order to explain why publishers in the 19th century began to have their books bound, and why decorated clothbindings were so successful as the Western world transitioned into modernity. This study

Sheep's fescue, Festuca ovina, is a common grass found all over Eurasia. In populations in southern Sweden some individuals were found to have two copies of the gene for cytoplasmic phosphoglucose isomerase, PgiC. The second copy, PgiC2, was first believed to be a duplicate of the original gene, PgiC1, but comparisons showed that this is not probable. The PgiC2 locus comprises two PgiC2 genes that

Popular Abstract in Swedish Denna avhandling handlar om modeller inom partikelfysik, vilka beskriver naturens minsta beståndsdelar. För att studera dessa små grundläggande byggstenar behöver man hög energi. Desto st ¨orre energi ju mindre avstånd kan man studera. Med höga energier kan man se atomerna, och med ännu högre energier kan man se kärnan och elektronerna, som atomerna består av. Sedan 60-This thesis dealswith the field of high-energy particle physics. It ismainly concernedwith two issues: the “renormalization of effective field theories” and the “detection of hidden sectors”. The first two papers are dedicated to the renormalization issue while the second two deal with the hidden sectors. Renormalization is crucial when one calculates physical observables to a high degree of preci
