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

Sense of coherence (SOC), e.g. meaningfulness of life, is according to the sociologist A. Antonovsky a health-promoting construct, which has been used in a number of descriptive studies in various populations. The aim of this population-based cross-sectional study was to investigate if middle-aged women with a self-reported low level of SOC also differed in biological variables, e.g. related to gl

A number of finite element (FE) models have been developed, starting with a purely magnetic one. The magnetic model was verified against analytical solutions and the commercial FE-programme ANSYS. The magnetic model was then coupled to the wave-equation, resulting in a model governing linear magnetostriction. In the magnetostrictive model a property of two degrees of freedom, that is, displacement
