The fate and effects of 2,4,6-trinitrotoluene (TNT) at marine ammunition dumping sites are essentially unknown. The objective of this study was to examine the release from solid TNT to seawater when covered by sediment of two different types (sandy and fine-grained) and thickness (0, 1 2, and 4 cm), under different temperatures (5, 10, and 20 degrees C), and light conditions (ambient daylight and

In order to search for novel giant-magnetoresistance systems, we fabricated and investigated narrow constrictions in the layers of the ferromagnetic semiconductor (Ga,Mn)As. We found that constrictions a few hundred nanometers wide, tailored by means of the electron-beam lithography and wet etching, were not conducting at liquid helium temperatures unless illuminated, probably due to the trapping

Popular Abstract in Swedish Yrsel är ett vanligt förekommande symtom hos patienter som besöker primärvården. Det är det vanligaste symtomet hos äldre patienter och har identifierats som en riskfaktor för fall och nedsatt funktion i innerörats balansorgan har hittats hos patienter med höftfrakturer och handledsfrakturer. Man har också påvisat att 25 % av patienterna med kvarstående besvär efter whiDizziness is a common reason for visits to primary health care, especially among elderly patients. From a physiotherapeutic perspective, this thesis aims to study the assessment and treatment of dizzy patients in primary health care. Interventions in papers I, III and IV comprised a vestibular rehabilitation programme. In paper I, patients with multisensory dizziness were randomized to interventi

Ozone in the atmosphere, mainly in the stratosphere, absorbs most of the ultraviolet-B (wavelength 280-315 nm) radiation from the sun, which can destroy DNA and other biologically important molecules and, thereby, damage living organisms. Due to the pollution of the atmosphere by humans, the ozone layer is presently being depleted, more rapidly at higher latitudes than at lower, and more rapidly o

BACKGROUND: Severe alpha 1-antitrypsin (AAT) deficiency (PiZZ) is associated with an increased risk of lung emphysema, especially in smokers. The aim of this study was to identify risk factors other than smoking for declining lung function. METHODS: Lung function was studied in 225 self-reported never-smoking PiZZ individuals included in the Swedish AAT deficiency register. RESULTS: Lung function

Bacterial infection and inflammation result in massive changes in serum glycoproteins. These changes were investigated by the interaction of the saccharide glycoprotein moiety with lectins. A panel of eight lectins (Canavalia ensiformis, Bandeiraea simplicifolia BS-I, Arachis hypogaea, Phytolacca americana, Phaseolus vulgaris, Artocarpus integrifolia, Triticum vulgaris and Pisum sativum) was used

The aim of this study was to evaluate the efficacy and toxicity of paclitaxel given at the same dose intensity and administered weekly (arm A) or every 3 weeks (arm B), and to assess the safety of intravenous steroids versus standard peroral premedication. Two hundred and eight patients with advanced ovarian cancer previously treated with no more than one platinum-containing regimen were randomize

The emission of NOx and-N2O were studied experimentally in a fluidized bed biomass combustor. To investigate effectively the influence of different parameters on the NOx formation with a limited number of experiments, an orthogonal experimental design was adapted. Four biomass fuels, three NOx-repressing additives, four bed materials, and four alkali-capturing additives were tested in a temperatur

A set of fossil bones from Romania has been analysed by accelerator mass spectrometry and by neutron activation analysis in order to estimate their age. The temporal attributing of Malu Rosu archaeological settlement has been extensively analyzed. The radiocarbon age, determined by accelerator mass spectrometry, for this site is 5510+/-200 BP. This is in agreement with the age of 6000+/-2000 BP, o

The objective of this investigation was to examine the relationship between leisure-time occupations, quality of life disease activity among patientswith rheumatoid arthritis. Fifty patients with rheumatoid arthritis-39 females and 11 males, age 30-45 years and belonging to functional class I-III according to Steinbrocker er al (1949)-were recuited from the register at a hospital clinic and from a

Popular Abstract in Swedish Ämnet för föreliggande avhandling är filosofisociologi. Filosofisociologin är en underavdelning till kunskapssociologin. Som framgår av namnet intresserar sig denna disciplin för det sociologiska studiet av filosofin. I och med att detta område är tämligen outforskat är denna avhandling i hög grad explorativ till sin karaktär. Betraktad som en helhet syftar avhandlingenThe subject matter of the present doctoral thesis is the sociology of philosophy, a sub-discipline within the general field of sociology. As the term clearly indicates, the sociology of philosophy concerns the sociological study of philosophy. As this domain is still, to some extent, virgin territory, my thesis is mainly explorative in nature. Viewed as a whole, it aims at investigating what a soc
