Denna rapport redovisar resultat från en genomgång av Småhusskadenämndens arkiv. I genomgången av arkivet studerades uteluftsventilerade krypgrunder som haft fukt- och mögelskador och åtgärdats för dessa med bidrag från nämnden. Småhusskadenämnden inrättades 1986 och har under perioden 1986 - 1997 behandlat 9.227 ärenden av vilka cirka 35 % har beviljats bidrag. Ur detta material valdes 102 grunde
A gene cluster from the white-rot basidiomycete Trametes (Coriolus) versicolor (Tv) PRL 572 containing three structural genes, LPGIII, LPGIV and MPGI, was characterized. The genes are arranged in the same transcriptional direction, within a 10-kb region, and found to encode quantitatively dominant isozymes of lignin peroxidase (LP) and manganese peroxidase (MP). The second gene in sequence, LPGIV,
Erasure of data stored by use of photon echoes has been investigated as a function of data writing time and data storage time. The results clarify the requirements on laser phase and frequency stability for performing photon-echo data erasure. The analysis of phase and frequency stability of a light source by the photon-echo erasure process is illustrated. A theoretical analysis emphasizing the ph
The main motivation for this thesis, however not the only one, is the search for models for traffic in telecommunication networks. Traffic characterization and modeling are of great importance in the analysis and dimensioning of communication systems. During the last decades we have experienced an explosive growth of our telecommunication networks. New important properties, both on macroscopic and
In this article garbage, waste, and disposal are discussed from a cultural theoretical perspective.
A six-year old boy presented with prolonged unexplained fever caused by an infected teratoma of the lower posterior mediastinum. Modern imaging, combining ultrasonography with computed tomography, enabled the correct diagnosis of topography, extension and nature of this rare lesion to be made and explained the clinical features. Follow-up CT showed regression of the abscess after antibiotics thus
Introduction: Endotoxemia developing during cardiosurgery as elevated endotoxin concentrations in patient's serum may prevail over 24 h after operation. A major reason is thought to be increased gut permeability resulting in endotoxin and bacterial leakage. In this study we aimed to measure endotoxin levels on samples obtained during and after cardiovascular procedures and compare them with clinic
Twenty patients who had been treated with a silicone rubber trapezial implant for degenerative changes in the first carpometacarpal joint were evaluated radiologically and clinically. After a mean follow up of 4.5 years, 11 of the 20 required reoperation and removal of the prosthesis for persisting pain and weakness. In all hands in which the prosthesis remained radiographs showed bone resorption
We have demonstrated that nickel adatoms self-assemble into quasi one-dimensional nanowires on vicinal Rh(111) surfaces by decorating their regular monoatomic step arrays, while V adatoms do not. The step decoration process has been followed experimentally by variable-temperature scanning tunnelling microscopy and high-resolution X-ray photoelectron spectroscopy. The physical origin of the differe
INTRODUCTION--Elderly patients with isolated acute vertigo are commonly encountered in clinical practice, but little is known about the underlying cause of the symptoms. MATERIAL & METHODS--We prospectively studied 24 patients aged 50-75 years with the acute onset of isolated vertigo lasting > 48 h and no abnormality on neurological examination other than nystagmus. The study protocol included
Popular Abstract in Swedish Avhandlingen behandlar målgruppsanalysens betydelse för budskapsformning och planering av informationskampanjer. Boken innehåller en genomgång av teorier som kan ligga till grund för målgruppsanalys samt för attityd- och beteendeförändring. Teorierna tillämpas så långt det varit möjligt i en målgruppsanalys av unga trafikanter i åldern 18-24 år. Målgruppsanalysen beståThe empirical work rests on two separate theoretical foundations: theories that form the basis for analyzing the different target groups and theories dealing with persuasion. Theories of the first sort concern life-style, individual values, perceived risk, individual characteristics and self-image. Earlier research on young car drivers is also relevant in this context. Theories on attitudes and at
Fourier transform (FT) spectra of Tl II with resolved hyperfine structure (hfs) have been analyzed in the region 1790-3400 Angstrom. Measured isotope shifts (IS) for two transitions, including the S-1-P-3 intercombination line to the ground state at 1908.6 Angstrom are reported. Accurate Ritz wavelengths for isotope and hyperfine components of the S-1-P-1 resonance line at 1321.6 Angstrom are give
The superior surfactant properties of cationic gemini surfactants are applied to the complex problem of introducing genes into cells. Of almost 250 new compounds tested, of some 20 different structural types, a majority showed very good transfection activity in vitro. The surfactant is shown to bind and compact DNA efficiently, and structural studies and calculations provide a working picture of t
Phase equilibria in ternary systems ionic surfactant-long chain alcohol-water are discussed in relation to Per Ekwall's pioneering contributions to the field. It is described how modeling of the thermodynamic behavior leads to a better understanding of what molecular interactions cause the rich phase behavior of these systems.
Modern sunscreens contain particles like TiO2 having sizes of 25-70 nm and acting as a reflecting substance. For cosmetic reasons the particle size is minimized. Questions have been raised to what degree these nano particles penetrate the skin barrier, and how they do affect the human. The EU funded project "Quality of skin as a barrier to ultra-fine particles" - NANODERM has started with the purp
