The histamine- and pancreastatin- containing ECL cells in the acid-producing mucosa of the rat stomach operate under the control of circulating gastrin. The present work examines how cholecystokinin (CCK)-B/gastrin receptors regulate the activity of the ECL cells. The oxyntic mucosal histidine decarboxylase (HDC) activity and the circulating pancreastatin concentration are two markers for the acti

Popular Abstract in Swedish Operation för ljumskbråck är den vanligaste operationen inom kirurgin. Sjukdomen drabbar främst män och till största delen de som är i arbetsför ålder. Årligen utförs ca. 20.000 operationer i Sverige. Allt sedan den berömde italienske kirurgen Edoardo Bassini introducerade sin operationsmetod för över 100 år sedan har återfalls-frekvensen varit ca. 15%-20% förutom vid sInguinal hernia repair is the most common operation in general surgery and the main challenge has been to lower the recurrence rate. With the introduction of endoscopic repair in the beginning of the 1990´s, the demand for randomised controlled studies has increased resulting in a growing interest in this surgical field. Standardised techniques with a growing use of tension free mesh repairs, teac

In a paper by Dai and Molisch (see Proc. IEEE VTC 2002 Spring, Birmingham, AL, May 2002), space-time layered architectures (BLAST) and turbo coding/processing techniques, which are effective for single-link transmission, are combined with multiuser detection (MUD) methods for combating intercell interference. It is shown that, depending on the channel configuration, linear MMSE or successive inter

Automatic construction of shape models from examples has recently been the focus of intense research. These methods have proved to be useful for shape segmentation, tracking, recognition and shape understanding. In this paper we discuss automatic landmark selection and correspondence determination from a discrete set of landmarks, typically obtained by feature extraction. The set of landmarks may

Understanding the risk management system is very important in studying and managing risks. In this report, attempts have been made to provide “state-of-the-art” knowledge and contribute to enhancing understanding in the field of risk management and methodology. Numerous risk assessment frameworks and risk analysis techniques, and some of the world’s best practices employed in shipping and other in

Digital forensic investigators experience a need for support in their everyday struggle to overcome boundary problems associated with cyber crime inves-tigations. Traditional methods are socio-culturally and physically localised and dependent on strict and historically prescriptive political management. The new internet-worked cyber-world creates unprecedented difficulties for digital forensic inv

Popular Abstract in Swedish I denna avhandling studeras europaskildringarna i James Weldon Johnsons The Autobiography of an Ex-Colored Man (1912), Jessie Fausets There Is Confusion (1924) och Nella Larsens Quicksand (1928) och hur dessa speglar afrikansk-amerikanernas roll i den västerländska civilisationen. I 1800-talets afrikansk-amerikanska litteratur figurerar Europa ofta som symbol för frihetThis thesis investigates the relationship between the “New Negro” moment of the early twentieth-century America and the Old World of Europe, as represented in James Weldon Johnson’s The Autobiography of an Ex-Colored Man (1912), Jessie Fauset’s There is Confusion (1924), and Nella Larsen’s Quicksand (1928). In the nineteenth century, Europe functioned as a symbol of freedom, education and art in t

Female religious communities, and later also convents, accompanied the return of the Roman Catholic Church to the Nordic countries in the middle of the nineteenth century. These religious communities were mostly so-called active orders or congregations, who helped in parishes or ran private schools, orphanages or nursing homes. In the 1930s there were nearly 1,400 Catholic sisters working in Scand

Popular Abstract in Swedish I det moderna samhället är vi helt beroende av polymera material, från barndomen med blöjor och nappflaskor till ålderdomen med artificiella ögonlinser och höftleder. Dagens sjukvård skulle inte klara de höga hygieniska kraven om inte engångsartiklar såsom gummihandskar, påsar för blodtransfusion och katetrar fanns. I många applikationer är polymerernas ytegenskaperna mThis thesis describes the preparation, characterisation and properties of poly(ethylene-graft-ethylene oxide) (PE-PEO). The grafting reaction was carried out with the grafting onto method using the carboxylic acid groups of poly(ethylene-co-acrylic acid) (PEAA) as reactive sites in an esterification reaction with poly(ethylene oxide) mono-methyl ethers (MPEO) of varying molecular weights: 750, 200
