Transient direct and inverse scattering for inhomogeneous viscoelastic media:Obliquely incident SH mode

A stratified viscoelastic medium in the time domain is characterised by two creep compliances that are functions of time and depth, and a density that is a function of depth. In this paper the direct scattering problem of a plane horizontal shear wave obliquely incident on a stratified viscoelastic medium is treated in detail. A general discussion of the corresponding inverse problem is given. A s

E-business and e-supply strategy in small and medium sized businesses (SMEs)

The purpose of this research was to investigate e-business and e-supply strategies in Scottish small- and medium-sized enterprises (SMEs). The paper reviews academic literature and recent survey reports on the degree of e-business adoption in the UK and Republic of Ireland. The qualitative methodology undertaken is described, findings are discussed and implications from this study for e-business s

A biomechanical study on fixation stability with twin hook or lag screw in artificial cancellous bone

The twin hook has been developed as an alternative to the conventional lag screw to be combined with a barrelled side-plate in the treatment of trochanteric hip fractures. With two oppositely directed apical hooks introduced into the subchondral bone of the femoral head, the twin hook provides different stabilising properties to the lag screw. The femoral head purchase of the twin hook and the lag

God in the Fourth Gospel : A Hermeneutical Investigation of the History of Interpretations

Popular Abstract in Swedish Bibeln, och framför allt Nya Testamentet, har präglat det västerländska tänkandet i en utsträckning som inte alltid noteras i nyare historieskrivning. En ledande roll har spelats av de uppfattningar av Gud som förmedlas av de fyra evangelierna. Inte minst har läsningar av Johannesevangeliet genomsyrat de kristna tänkarnas försök att formulera synen på Guds väsen, egenskThis book presents an exhaustive and systematic investigation of six representatives of three important periods of New Testament interpretation: Martin Luther, John Calvin, Brooke Foss Westcott, Heinrich Julius Holtzmann, Rudolf Bultmann and Raymond E. Brown. They serve as dialogue partners in an investigation of the notion of God in the Fourth Gospel, a topic that has been called “the neglected f

Carbon allocation in mycelia of arbuscular mycorrhizal fungi during colonisation of plant seedlings

The direction of carbon (C) allocation in mycorrhizal mycelia is of fundamental importance to coexistence of individual plants. We therefore investigated the transfer of C from established plants to plant seedlings through fungal mycelia. C allocation by the arbuscular mycorrhizal (AM) fungus Glomus intraradices, from 'donor' plants to mycelia in soil and two different species of introduced 'recei

Essays on Sickness Insurance, Absence Certification and Social Norms

Popular Abstract in Swedish Avhandlingen består av ett inledande kapitel och tre essäer, som studerar sjukpenningförsäkringen, sociala normer och sjukskrivning. Den första essän, Group-Specific Social Norms and Economic Incentives in a General Welfare System, behandlar interaktionen mellan ekonomiska och sociala drivkrafter i ett generellt bidragssystem. Vi anknyter resultaten till sjukpenningförThe thesis consists of an introductory chapter and three essays, considering sickness insurance, social norms and absence certification. The first essay, Group-Specific Social Norms and Economic Incentives in a General Welfare System, investigates the interaction between economic incentives and social influences in a general welfare system. We relate the results to sickness insurance. The model i

Prediction of upper respiratory tract bacteria in acute otitis media

Conclusions. Thorough otomicroscopical examination of the tympanic membrane in acute otitis media (AOM) might distinguish AOM episodes caused by different bacteria. It thus might be a way to select appropriate treatment for each patient without raising the number of dangerous complications. Objectives. The aim of this study was to see if it might be possible to predict the causative bacterium by j

C-36 peptide, a degradation product of alpha1-antitrypsin, modulates human monocyte activation through LPS signaling pathways.

alpha 1-Antitrypsin (AAT), a major endogenous inhibitor of serine proteases, plays an important role in minimizing proteolytic injury to host tissue at sites of infection and inflammation. There is now increasing evidence that AAT undergoes post-translational modifications to yield by-products With novel biological activity. One Such molecule, the C-terminal fragment of AAT, corresponding to resid

Intra- and extracellular forms of lipoprotein lipase in adipose tissue

The location of lipoprotein lipase activity in rat adipose tissue was studied using intact epididymal fat pads, isolated adipocytes, and lipoprotein lipase activity secreted from adipocytes as enzyme sources. The enzyme activities of these preparations were characterized by gel filtration. The method used for isolation of adipocytes had been modified to minimize activation of lipoprotein lipase du

Concentrations of retinoids in early pregnancy and in newborns and their mothers.

Background: Retinoids are vital for embryonic development; both excesses and deficiencies of vitamin A are known to give similar patterns of birth defects. Concentrations of retinol in newborns and in pregnant women have been investigated, but concentrations of the biologically active metabolite all-trans retinoic acid and its isomer 13-cis retinoic acid have not. Objective: We measured serum conc

Trypanocidal diarylheptanoids from Aframomum letestuianum K. Schum (Zingiberaceae).

Three new diarylheptanoids, (4Z,6E)-5-hydroxy-1-(4-hydroxy-3-methoxyphenyl)-7-(4-hydroxyphenyl)hepta-4,6-dien-3-one, letestuianin A (1), (4Z,6E)-5-hydroxy-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-4,6-dien-3-one, letestuianin B (2), and 1,7-bis(4-hydroxyphenyl)heptan-3,5-dione, letestuianin C (3), as well as the known (4Z,6E)-5-hydroxy-1,7-bis(4-hydroxyphenyl)hepta-4,6-dien-3-one (5) were isolated f
