Generation, characterization, and medical utilization of laser-produced emission continua

Intense continua of electromagnetic radiation of very brief duration are formed in the interaction of focused ultra-short terawatt laser pulses with matter. Two different kinds of experiments, which have been performed utilizing the Lund 10 Hz titanium-doped sapphire terawatt laser system are being described, where visible radiation and X-rays, respectively, have been generated. Focusing into wate

A cross-sectional study of the Birmingham Vasculitis Activity Score version 3 in systemic vasculitis.

Objective. Assessment of disease activity in vasculitis can be achieved using the BVAS, a clinical checklist of relevant symptoms, signs and features of active disease. The aim of this study was to revalidate the BVAS version 3 (BVAS v. 3) in a cohort of patients with systemic vasculitis. Methods. A total of 238 patients with vasculitis from seven countries in Europe were evaluated at a single tim

The meniscus in knee osteoarthritis.

The meniscus is a critical tissue in the healthy knee joint because of its shock absorption and load distribution properties. Meniscal damage is a frequent finding on MRI of the osteoarthritis (OA) knee. The damage appears as horizontal, flap, or complex tears; meniscal maceration; or destruction. Asymptomatic meniscal lesions are common incidental findings on knee MRI of the middle-aged or older

Hand deformities are important signs of disease severity in patients with early rheumatoid arthritis.

Objectives. The aim of this study was to investigate the occurrence and significance of hand deformities during the first 10 years of RA. Methods. One hundred and eighty-three early RA patients were included in the study during 1985-89. Mean +/- s.d. of age at onset was 51.4 +/- 12.4 years, and mean duration of symptoms before inclusion 12 +/- 7 months; 64% were women. The patients were followed a

Contract-workers in Swedish agriculture, c. 1890s – 1930s. A comparative study of standard of living and social status

In the political and medial discourse of the 1930s the contract-work system (stat/ar/ systemet) was depicted as a relic of pre-modern society and contract-workers (statare) as the highly exploited lower class with no legal rights, low incomes, miserable housing conditions and a chaotic family life. This picture has dominated Swedish social history ever since, and the main argument of this article

Multivariate and Multiscale Monitoring of Wastewater Treatment Operation

In this work extensions to principal component analysis (PCA) for wastewater treatment (WWT) process monitoring are discussed. Conventional PCA has some limitations when used for WWT monitoring. Firstly, PCA assumes that data are stationary, which is normally not the case in WWT monitoring. Secondly, PCA is most suitable for monitoring data that display events in one time-scale. However, in WWT op

Antiproliferative effects of peracetylated naphthoxylosides.

The antiproliferative activity, and the capability of priming of glycosaminoglycan chains, of two series of peracetylated mono- and bis-xylosylated dihydroxynaphthalenes have been investigated for normal HFL-1 cells, as well as transformed T24 cells, and compared to the unprotected analogs. Our data show increased antiproliferative activity upon peracetylation, but a loss of selectivity towards T2

Psychometric properties of the consumer emergency care satisfaction scale: tested on persons accompanying patients in emergency department.

The aim of this study was to investigate construct validity and internal consistency of a modified version of the Consumer Emergency Care Satisfaction Scale used on persons accompanying emergency department patients. The sample comprised 128 persons. The results showed satisfactory reliability, and an exploratory factor analysis revealed 3 factors: caring, teaching, and clinical competence. The mo

Constraint Programming Methods for Optimization of Single Shortest Path Routing

In this thesis, we propose methods based on constraint programming (CP) for solving an optimization problem in telecommunications, the single shortest path routing problem. The problem is to find optimal values for a set of routing configuration parameters in a shortest path routing protocol, for a given network. With optimal parameters, traffic is routed through the network in a way which is opti

A novel fabrication technique for free-hanging homogeneous polymeric cantilever waveguides

We present a novel bonding technique developed for the fabrication of a cantilever-based biosensing system with integrated optical read-out. The read-out mechanism is based on single-mode waveguides fabricated monolithically in SU-8. For optimal operation of the read-out mode, the cantilever waveguides should be homogenous and this bonding technique ensures free-hanging cantilevers that are surrou
