1. A Detector System for Light–Element Analysis using a Nuclear Microprobe : for Applications in Geoscience
Sammanfattning : I detta arbete har två analysmetoder med mycket hög känslighet för att mäta väte och bor utvecklats. Dessa har tillämpats på geologiska material där de kan vara ett verktyg i att svara på frågeställningar gällande b.la. jordskorpans utveckling och flödet av vatten på jorden. LÄS MER
2. Compton Scattering from the Deuteron at Low Energies
Sammanfattning : A series of three Compton scattering experiments on deuterium have been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 50 < Eg < 70 MeV tagged photons were scattered from a liquid deuterium target and detected simultaneously in three (10"x10") NaI detectors. LÄS MER
3. Being active in working life at older ages
Sammanfattning : The overall aim of the thesis was to examine factors associated with (Study 1), predictors (Study II), and experiences (Study III) involved with being active in working life after the expected retirement age and the experiences of exiting working life before the expected retirement age (Study IV). In Studies I and II, a quantitative approach was used, with data derived from the Swedish National Study on Aging and Care (SNAC). LÄS MER
4. Upper Extremity Musculoskeletal Disorders In Female Machine milkers - An Epidemiological, Clinical and Ergonomic Study
Sammanfattning : The aims of the thesis were to investigate the prevalence of the upper extremity musculoskeletal disorders in female milkers in relation to other occupational groups; to clarify the relationship between disorders and work environment, psychosocial and life style factors; to compare in a prospective study, pain, ache and discomfort reported by a questionnaire with clinical symptoms and sign; to examine milkers with wrist and hand disorders with regard to type and localization of the tissue injury; to quantify the work load on forearms, wrists and hands during machine milking. An increased risk developing symptoms in wrists and hands was noted in the active milker group compared to the non-milker and the nursing assistant group. LÄS MER
5. Spectroscopic Investigations of Highly Charged Tungsten Ions - Atomic Spectroscopy and Fusion Plasma Diagnostics
Sammanfattning : The spectra of highly charged tungsten ions have been investigated using x-ray and extreme ultraviolet spectroscopy. These heavy ions are of interest in relativistic atomic structure theory, where high-precision wavelength measurements benchmark theoretical approaches, and in magnetic fusion research, where the ions may serve to diagnose high-temperature plasmas.
