An entity is described which is characterized by low back pain and increased radionuclide uptake in the sacrum at bone scintigraphy in postmenopausal women having received radiotherapy towards the pelvis because of gynaecological malignancy. The findings stimulate bone metastases, but are in all likelihood caused by insufficiency fractures of the sacrum promoted by bone weakness induced by postmen
We have developed high-throughput tests for the detection of the insulin gene region SNPs -23HphI and -2221MspI. The potential of these markers to enhance the efficiency of type I diabetes risk screening was then evaluated by analyzing them in Finnish and Swedish populations. Blood spots on filter paper were analyzed using PCR followed by sequence- specific hybridization and time-resolved fluorome
Naturgas är ett rent bränsle som endast innehåller små mängder föroreningar, [1]. Jämfört med kol är föekomsten av föroreningar i naturgas vanligen 1000 ggr mindre. Man får därför inga problem med svaveldioxid, tungmetaller, klorerade föroreningar etc i avgaserna. Vid normal drift bildas mycket lite sot och de huvudsakliga förbränningsprodukterna är vatten och koldioxid. Vatten ställer normalt int
OBJECTIVE: To determine if the frequency of alpha 1AT deficiency (PiZ) is increased in patients with abdominal aortic aneurysm (AAA), and, to investigate whether aneurysmal stiffness and other clinical characteristics differ in AAA patients with and without alpha 1AT deficiency. METHODS: We identified alpha 1AT-deficient individuals by a monoclonal-antibody ELISA technique, in 102 consecutive pati
Biotechnological leaching has been proposed as a suitable method for extraction of vanadium from spent catalysts and oil ash. In the biological leaching process, the vanadium(V) can be reduced to vanadium(IV), which is a less toxic and more soluble form of the vanadium. The present investigation showed that Acidithiobacillus ferrooxidans efficiently reduced vanadium(V) in the form of vanadium pent
An on-line microdetector containing amperometric biosensors was used for high temporal resolution (t(90%) approximate to 120 s) monitoring of glucose and ethanol concentrations during small scale fermentations. ne ability of the microdetector to report on the effect of different experimental conditions was tested in fermentation processes carried out at 30 and at 37 degrees C. An increased ethanol
Popular Abstract in Swedish Huvudsyftet med studien har varit att ta fram matematiska samband för dimensionering av processutrustning – dimensionering är ett klassiskt ingenjörsproblem. Korrekt dimensionering är viktig för att utrustningen skall fungera tillfredsställande och dessutom inte resultera i onödiga investerings- och driftskostnader. Den matematiska modell (en uppsättning ekvationer) soA study concerning closure relations pertinent to the design of sorption equipment of absorption heat pumps has been undertaken. Specifically, thermosiphon and vertical falling film arrangements were studied. For the thermosiphon, experimental data on the void fraction, the friction and orifice pressure drops, and the heat transfer coefficient at sub-atmospheric pressures were obtained for vapori
The aim of this study was to describe first-time mothers' views of satisfaction with their first encounter with the nurse, in order to investigate differences between home visits and clinic visits and between high/middle and low socioeconomic classification (SEC). A nation-wide postal questionnaire sent to 800 first-time mothers yielded the data for statistical analysis. Data were collected using

Eighteen groups of guinea pigs were exposed to a simulated impact noise for periods of 1.5-24 h. The peak level was kept constant at 131.5 dB and the repetition rate was varied to give seven different equivalent levels (Leq) between 96 and 117 dB. The auditory thresholds were assessed by electrocochleography after 1 month and compared with those of a control group. Significant damage occurred even
Background: Several countries are discussing new legislation on the ban of smoking in public places, and on the acceptable levels of traffic-related air pollutants. It is therefore useful to estimate the burden of disease associated with indoor and outdoor air pollution. Methods: We have estimated exposure to Environmental Tobacco Smoke (ETS) and to air pollution in never smokers and ex-smokers in
Infrared and collinear safe event shape distributions and their mean values are determined in e(+)e(-) collisions at centre-of-mass energies between 45 and 202GeV. A phenomenological analysis based on power correction models including hadron mass effects for both differential distributions and mean values is presented. Using power corrections, alpha(s) is extracted from the mean values and shapes.
