Small bowel carcinoid tumor (SBC) is a rare disease of unknown etiology bill with all age-, sex-, and place-specific occurrence that may indicate an occupational origin. A European multicenter population-based case-control study was conducted from 1995 through 1997. Incident SBC cases between 35 and 69 years of age (n = 101) were identified, together with 3335 controls sampled from the catchment a

Birds appear to use their tails during flight, but until recently the aerodynamic role that tails fulfil was largely unknown. In recent years delta-wing theory, devised to predict the aerodynamics of high-performance aircraft, has been applied to the tails of birds and has been successful in providing a model for the aerodynamics of a birds tail. This theory now provides the conventional explanati

Non-radiative decay of core excitations at the B 1s and N 1s absorption edges of bulk hexagonal boron nitride (h-BN) has been studied with resonant Auger spectroscopy. In order to reproduce the bulk properties of the sample while keeping it electrically conducting, we have grown reasonably thick (more than 20nm) polycrystalline films of h-BN on a Ni(111) surface by thermal cracking of borazine vap

Popular Abstract in Swedish Den sedimentära lagerföljd som bygger upp Gotland avlagrades för drygt 400 miljoner år sedan (under silurperioden) i ett varmt tropiskt innanhav strax söder om ekvatorn. Innanhavet sträckte sig som en vid bukt in över dagens södra Skandinavien, Baltikum och vidare mot sydost, till Ukraina. Avhandlingen behandlar primärt hur sedimentationsmönster utvecklades under cirka The Silurian foreland of Scandinavia included a vast epicontinental carbonate platform system of which the island of Gotland (Sweden) is an erosional remnant. This thesis treats the Late Wenlock succession (Cyrtograptus lundgreni, Pristiograptus dubius parvus, Gothograptus nassa, Colonograptus(?) praedeubeli, and the Co(?) deubeli zones), and emphasises the sedimentology and biostratigraphy of the

High spin states in the nucleus Tc-91 have been studied via the fusion evaporation reaction Ni-58(Ar-36,3p)Tc-91, at 149 MeV and 140 MeV beam energy. The OSWS spectrometer, an additional high purity Ge detector at 162 degrees, and several particle detectors were used to measure gamma gamma- and particle-gamma coincidences, directional correlations of oriented states, and line shapes due to Doppler

The title compound, [ RhCl( PBz(3))(2)( CO)] [ PBz(3) = tribenzylphosphine, P(C7H7)(3)], which is the first reported tribenzylphosphine - rhodium( I) structure, has pseudo- square- planar coordination geometry, with Rh - P bond distances of 2.3164 ( 15) and 2.3156 ( 16) Angstrom. The Rh - Cl, Rh - C and C - O bond distances are 2.3654 ( 15), 1.783 ( 6) and 1.162 ( 6) Angstrom, respectively, and th

Significance of eco-friendly materials based on easily renewable natural resources, and the finite nature of petrochemical resources, has necessitated the development of polymers from agricultural processing by products such as soy proteins from oil processing. Although, considerable work was done in the early part of last century on polymers based on soy protein, there was almost no activity in t

Breast ducts contain two types of epithelial cells, inner luminal cells and outer basal/ myoepithelial cells. These cells can be distinguished by their immunophenotype. Cytokeratins ( CKs) 8 and 18 are expressed in the luminal layer, whereas CK5/ 14 and the transcription factor p63 characterize the basal epithelial layer. We studied a population- based cohort of 288 sporadic ductal invasive cancer

Information on the effects of thyroid hormone on smooth muscle contractile protein expression and mechanical properties is sparse. We have addressed the following questions. (1) Can thyroxine hormone alter myosin isoform composition in smooth muscle? (2) Can a change in myosin isoform composition lead to altered mechanical properties in smooth muscle? (3) Are alterations, if occurring, equal in fa

Trilobites from the Middle and Upper Ordovician Andersön Shale Formation in Jämtland, central Sweden, and the Middle Ordovician Killeröd Formation in Skåne (Scania), southern Sweden, are revised and discussed. These formations have several genera and a few species in common, e.g. Botrioides efflorescens (Hadding, 1913a) and Pseudomegalaspis patagiata (Törnquist, 1884). The regional and vertical di

A group of Swedish oncologists and hospital physicists have estimated the number of patients in Sweden suitable for proton beam therapy. The estimations have been based on current statistics of tumour incidence, number of patients potentially eligible for radiation treatment, scientific support from clinical trials and model dose planning studies and knowledge of the dose-response relations of dif

Blood group ABO polymorphism was analysed in genomic DNA isolated from 150 blood donors by restriction endonuclease digestion of three polymerase chain reaction-amplified exons in the ABO genes and by sequencing of randomly selected samples. An anomalous O1 allele first described in a cancer cell line is now shown to account for approximately 40% of the O alleles described to date. This is 10 time

Popular Abstract in Swedish Reformationens budskap brukar karakteriseras med hjälp av några "allena": Kristus allena, tron allena, nåden allena och Skriften allena. I denna studie undersöks hur Martin Chemnitz (1522-86) behandlar dessa teman och hur han sätter dem i relation till Augustinus teologi. Martin Chemnitz var en av de mest framstående evangeliska teologerna i generationen efter Martin LuAs a co-author of the Formula of Concord, Martin Chemnitz (1522-86) codified the sola scriptura principle of the Reformation, that the prophetic and apostolic Scriptures are the only rule for all Church doctrine. This principle is clearly expressed in Chemnitz' own theological treatises as well, but in his argumentation one is also confronted with an astonishing number of quotations from the Churc
