Popular Abstract in Swedish Ett antal optiskt aktiva metalloorganiska Phe-AAn-Phe subenheter har syntetiserats via intramolekulär cyklisering av motsvarande bis(aminosyra)derivat. Bis(aminosyra)derivaten var i sin tur erhållna från en förbättrad multistegssyntes, vars nyckelsteg är Horner-Wadswort-Emmons olefinering av metalloorganiska aldehyder med fosfonylglycin-reagens, enantioselektiv hydrogenSeveral optically active organometallic Phe-AAn-Phe peptidomimetics and macrocyclic Phe-(Phe)n peptides have been synthesized by either intra- or intermolecular peptide bond formation of the corresponding bis(amino acid) derivatives. The key bis(amino acid) derivatives were available from an improved multi-step synthetic route, utilising Horner-Wadswort-Emmons olefination of organometallic aldehyd

Christopher Polhem (1661-1751), called the father of Swedish mechanics, is the most famous figure in Swedish history of technology and our nation's foremost inventor ever. Remarkably enough, a close survey in a monograph has never been written on this inventor who in many ways initiated the technical and industrial development of Sweden. In this project will Polhem for the first time get a broad a

Popular Abstract in Swedish Spårbarhet av livsmedel för att garantera ursprung, kvalitet och säkerhet i samband med produktion och transport har blivit alltmer uppmärksammat i samhället. Kraven på att livsmedel skall vara kvalitetsmässigt säkerställda samt miljömässigt hållbara har vuxit sig starkare från konsumenter såväl som från myndigheter. En bidragande orsak är den ökade fokuseringen kring bFood traceability is gaining increased attention in food companies and governmental authorities. This is because of the increase in legal and consumer requirements on ensuring food safety, quality and preservation of living resources. These requirements especially apply to the management of food traceability in regulated fresh food supply chains. Several studies have shown that management of food

This chapter takes its departure in the persistent mythology surrounding the so-called forest Finns who migrated from Finland to Sweden and further on to America in the seventeenth century. The forest Finns have traditionally been regarded as a clear-cut and bounded ethnical group, represented by a specific suit of material culture and practices. However, by comparing archaeological remains and wr

Mahler var under sin korta livstid en omstridd gestalt och hans musik har kämpat sig genom 1900-talets omvälvande historia för att idag utgöra en självklar del av repertoaren hos orkestrar världen över. Mahlers karriärväg gick genom ett omstörtande och dynamiskt Centraleuropa och arvet efter Mahler skulle komma att präglas av politiska och estetiska rågångar med rötterna i hans egen tid. I denna a

One of the greatest challenges for the archaeology of ritual and religion is to find ways to connect theoretical developments with the archaeological record. This article explores the possibilities of synchronizing archaeological methods and theories in our search for understanding ritual in the past through a concrete case study of a Mesolithic cemetery in Southern Scandinavia. The author argues

Popular Abstract in Swedish Vävnadskallikrein (VK) är ett äggvitespjälkande protein som dels kan aktivera vävnadsnedbrytande enzymer som kollagenas och gelatinas och dels spjälkar kininogen till kininer (bradykinin och kallidin). Via bindning till speciella kininreceptorer (B2 receptorer) som finns överallt i kroppen, styr kininerna olika processer i de flesta av kroppens organ och vävnader såsom Tissue kallikrein releases pharmacollogically highly active kinins from kininogen. Many other enzymes may also release kinins. The aim of the study was to clarify the pathophysiological role of tissue kallikrein in acute pancreatitis. Two sensitive and specific radioimmunoassays for porcine and human tissue kallikrein were developed. A large release of tissue kallikrein from the pancreatic gland

In this paper we present analytical expressions for the angle-of-arrival (AOA) power density function (PDF) and its application in geometrically based channel models for urban environments. We make comparisons with experimental results for wideband channel models, published in the open literature, in order to evaluate the theoretical clusters PDF in angle domain proposed. The comparison with exper

Since year 2000 a number of national energy management systems (EnMS) standards and specifications have been developed. To support EnMS implementation in industry some governments have launched agreements centered around energy management practices. National experiences show that such policy programs can achieve significant energy efficiency improvements. Implementation of industrial EnMSs has gra
