In summer 1987 most of the multibody dynamics community met at the JPL, Pasadena, to discuss the needs and the open problems in multibody system simulation, especially for space applications. P. W. Likins stated in his survey [16]: “Computational questions focused initially on the selection of subroutines for numerical integration, matrix inversion, or eigensystem analysis,and lately have shifted
Popular Abstract in Swedish Enterostatin är en peptid (en liten del av ett protein) som bildas i magsäcken och tarmen under en måltid. I djurförsök då råttor behandlas med enterostatin har man funnit att både aptiten och kroppsvikten minskade. Den minskade aptiten gällde speciellt för fett. Enterostatin fungerar som en mättnadssignal för fett och kan därför vara viktig för att hindra uppkomsten avThe presence of procolipase and enterostatin in the rat gastrointestinal tract has been investigated. Procolipase was identified, using in situ hybridization and immunohistochemistry, in exocrine cells of the pancreas as well as in chief cells of the fundus region of the stomach. Enterostatin is the activation peptide of procolipase and it has been found to act as a satiety signal for fat. Using a
The most common situation connection with freshwater production from sea water (desalination) is producing a brine waste stream, usually discharged back into sea water. The purpose of this study is to explore the behavior of a dense jet and bottom plume, composed of brine water of heavier effluent into a quiescent homogeneous ambient, discharged into a receiving body of lighter fresh water (tank).
Popular Abstract in Swedish Den mänskliga arvsmassan består bara till en begränsad del av gener som kodar för proteiner som används för livsnödvändiga funktioner. Så mycket som 50 % eller mer består av repetitiva sekvenser, dvs sådana DNA element som finns i 100-100.000-tals mer eller mindre identiska kopior. Man kan säga att dessa är genetiska parasiter som använder sig av den mänskliga cellens eHuman endogenous retroviruses (HERVs) are remains of ancient retroviral infections of the germ line and constitute as much as 3 % of the human genome. HERVs are genetic elements that potentially may provide important biological functions by several different mechanisms. The ability to transpose long after the initial insertion into the germ line may provide a potent source of insertional mutagenes
Popular Abstract in Swedish Den enorma variationen av beteenden och utseenden som återfinns i djurriket har i alla år fascinerat och länge förbryllat biologer. Rovdjurens skoningslösa utgallring är en av de stora drivkrafterna bakom evolutionen av alla dessa karaktärsdrag. Rovdjuren är såklart även en viktig strukturerande kraft i sötvattensmiljöer och har där lett till utvecklingen av mängder av The varieties of prey phenotypes that have been revealed in nature are vast and many of these phenotypes are the result of the selective force that predators have had on prey traits in the past. Even within species and populations we see variations due to both differences in the selection forces they live under but also due to individual trait variation. In this thesis I investigate both the direc

Popular Abstract in Swedish Hemolytiskt uremiskt syndrom (HUS) och trombotiskt trombocytopen purpura (TTP) är allvarliga sjukdomar hos barn och vuxna. HUS kännetecknas av mikroangiopatisk hemolytisk anemi (blodbrist med nedbrytning av röda blodkroppar), trombocytopeni (låga blodplättar) och akut njursvikt. Det är den vanligaste orsaken till akut njursvikt hos barn. Typisk HUS utlöses av tarminfektThis study investigated the pathogenesis of hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP). (1) The relative roles of lipopolysaccharide and Shiga-like toxin-2 were studied in a mouse model of Escherichia coli O157:H7 infection. Both factors were found to be important for the virulence of the strain and contributed in an additive manner. The mouse model mimicked cert

Leukotrienes are membrane derived bioactive lipids that play an important role in immune responses by initiating and maintaining the inflammatory responses. Leukotriene B4 (LTB4) released at the site of an inflammatory response attracts, activates and prolongs the life of leukocytes and lymphocytes. LTB4 can bind to two recently cloned cell surface G-protein coupled receptors named BLT1 and BLT2.
This study investigates the topic of forgiveness of sins in the mission of the historical Jesus. Gospel material that pertains to the question is authenticated by the use of criteria for historicity and interpreted within the wider context of first-century Judaism as part of a broader reconstruction of Jesus’ career as a healer and prophet. Questions posed and answered concern the historical plaus
Popular Abstract in Swedish Växternas respirationskedja innehåller protonpumpande enzymer, som konserverar energi i form av en protongradient, samt alternativa icke-protonpumpande enzymer. I det mitokondriella innermembranet finns ett protonpumpande NADH dehydrogenas, komplex I, och alternativa typ II NAD(P)H dehydrogenaser som kan oxidera NADH och NADPH från matrixen eller cytosolen. I ArabidopsiThe respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. The seven gene homologues of typ
As a result of the globalisation of the world economy, many enterprises that previously confined their business activities to national markets are now focusing on broader international markets, thus forming the basis for the establishment of global enterprises. In addition to the extension of markets, these global companies also seek cost reductions through scale economics in logistics, marketing,
