Prompt proton decay lines in Cu-58 have been studied by means of high-resolution in-beam particle-gamma coincidence spectroscopy using the GAMMASPHERE Ge-detector array in conjunction with a dedicated set of ancillary detectors including four DeltaE-E silicon-strip telescopes. High-spin states in Cu-58 have been populated via the heavy-ion fusion-evaporation reaction Si-28(Ar-36, 1alpha1p1n) at 14
High-spin states in Cs-123 were populated in the Ni-64(Ni-64,p4n) reaction at a beam energy of 265 MeV. Gamma-ray coincidences were measured using the Gammasphere spectrometer. Two additional bands have been placed in the level scheme and the four previously known bands have been extended to higher spin. At the highest spins, two of the bands show irregular level sequences. These structures of non
Hyaluronan is a free glycosaminoglycan which is abundant in the extracellular matrix of the developing brain. Although not covalently linked to any protein it can act as a backbone molecule forming aggregates with chondroitin sulfate proteoglycans of the lectican family and link proteins. Using neurocan-GFP as a direct histochemical probe we analyzed the distribution and organization of hyaluronan
Popular Abstract in Swedish Numeriska methoder har används för att beräkna turbulent strömning och värmeöverföring i komplexa kanaler med olika turbulens modeller.Th need for a reliable and reasonable accurate turbulence model without specific convergence problem for calculating duct flows in industrial applications has become more evident. In this study a general computational method has been developed for calculating turbulent quantities in any arbitrary three dimensional duct. Four different turbulence models for predicting the turbulent Reynolds stresse
En analys av ett par av Torsten Anderssons målningar.
Most of the Scandinavian members of the orchid genus Dactylorhiza are included in the D. incarnata/D. maculata polyploid complex. Molecular data obtained during the last decade have given a better understanding of evolutionary patterns in this complex and explain why it is taxonomically difficult. The data reveal that allotetraploids have been formed repeatedly by hybridization between the same pa
Development of type-II collagen (CII)-induced arthritis (CIA) is dependent on a T-cell mediated activation of autoreactive B cells. However, it is still unclear if B cells can present CII to T cells. To investigate the role of B cells as antigen-presenting cells (APCs) for CII, we purified B cells from lymph nodes of immunized and nonimmunized mice. These B cells were used as APC for antigen-speci
The aim of this study was to assess persistent organochlorine pollutant (POP) levels in serum collected from children (11-15 years old) working and sometimes also living at the municipal waste-disposal site in Managua, located at the shore of Lake Managua, and in nonworking children living both nearby and also far away from the waste-disposal site. The influence of fish consumption was further eva
Research into press reporting on young people has tended to concentrate on young people as offenders. In contrast, this article focuses on press coverage of teenagers as victims. Reports in two Swedish newspapers (a morning broadsheet and an evening tabloid) were studied over a period of four months and subjected to a qualitative analysis of discourse on teenagers as victims of various forms of vi
The potential use of in vitro-expanded precursor cells or cell lines in repair includes transplantation of such cells for cell replacement purposes and the activation of host cells to provide "self-repair." Recently, we have reported that cells from the brain-derived cell line RN33B (derived from the embryonic rat medullary raphe and immortalized through retroviral transduction of the temperature-
We present a search for excited neutrinos using e(-) p data taken by the H1 experiment at HERA at a center-of-mass energy of 318 GeV with an integrated luminosity of 15 pb(-1). No evidence for excited neutrino production is found. Mass dependent exclusion limits are determined for the ratio of the coupling to the compositeness scale, f/Lambda, independently of the relative couplings to the SU(2) a
Popular Abstract in Swedish Formstabilitet, dvs. förmågan för träet att behålla sin form, är en av de viktigaste parametrarna när trä används som byggnadsmaterial eller för andra ändamål. I allmänhet ändras träets dimensioner och form när dess fuktkvot ändras. Detta är dock inte önskvärt i konstruktioner, varför det behövs metoder som förbättrar formstabiliteten. I denna avhandling har inverkan aShape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. However, this can often not be tolerated in constructions and thus, methods to improve the shape stability have to be found. In th
The thermal insulation of a clothing ensemble can be measured with a thermal manikin or estimated according to ISO 9920. In ISO 9920 there are insulation tables for a number of clothing ensembles with specified garments and other tables for a variety of single garments. The insulation of single garments can be summated to estimate the insulation for a clothing ensemble. However, when a clothing en
A body of evidence points towards a close connection between susceptibility to fractures and osteoporosis. The incidence of osteoporotic fractures, both in absolute figures and in age-specific figures, has increased worldwide throughout this century. Although some reports show that the age-specific incidence is levelling-off, there will be a continuously increasing number of individuals with such
M2-type phases M3TeO10 (M = Mo and V), belonging to the Mo-V-Nb-Te-oxide system, were prepared by substituting to various degrees the M-metal with W, Ti, Nb or Fe, and Te with Ce. The compositions were characterized by BET, XRD and XPS and were studied for propene ammoxidation. The variations of the unit cell parameters with substitution reveal that the orthorhombic, pseudo-hexagonal M2 structure
