Abstract in Undetermined This work tackles the problem of interferometric phase estimation in the presence of layover by using nonuniform multibaseline interferometric synthetic aperture radar systems. The effects of nonuniform sampling on Fourier-based and superresolution spectral estimation methods are investigated. The impact on both the spectral properties and on the interferometric phase esti
Popular Abstract in Swedish Störningar i händernas finmotorik, kraft och känsel är vanliga symtom efter långvarigt bruk av handhållna vibrerande verktyg. I gynnsamma och lindriga fall kan dessa besvär gå tillbaka efter upphörande av expositionen för vibrationer. I mer avancerade fall tilltar besvären och ett hand-arm vibration syndrom (HAVS) utvecklas. Detta tillstånd utgör ett av de allvarligare Exposure to vibration is known to cause vasospastic white fingers and/or sensorineural symtoms such as numbness and tingling in fingers and/or musculoskeletal disorders such as reduction in muscle force, fatigue and reduced endurance. Classifications for the vasospastic and sensorineural symptoms are established. The general purpose of this thesis was to test the hypothesis that vibration exposur
Steady flow in axial one-stage turbines is assessed numerically and experimentally. The simulations are performed on coarse meshes using a standard numerical approach (3D, steady state, kε-turbulence model, wall function at solid boundaries). In order to allow for conclusions drawn from these rapid numerical studies, the approach was compared with an explicit LDA (Laser Doppler anemometry) mapping
Amusement parks offer rich possibilities for physics learning, through observations and experiments that illustrate important physical principles and often involve the whole body. Amusement parks are also among the most popular school excursions, but very often the learning possibilities are underused. In this work we have studied different teacher roles and discuss how universities, parks or even
Bolivia has the most varied ecology in South America - the Amazonas rainforests, the dry forests of the Chaco, the mist forests, the punas and high Andean vegetation. Some general studies have been carried out on useful plants; traditional medicine has been practiced in parts of region for thousands of years, recognized and accepted for treatment of various diseases. Some of these widely used medi
The Working Group III Special Report on Renewable Energy Sources and Climate Change Mitigation (SRREN) presents an assessment of the literature on the scientific, technological, environmental, economic and social aspects of the contribution of six renewable energy (RE) sources to the mitigation of climate change. It is intended to provide policy relevant information to governments, intergovernment
Popular Abstract in Swedish Vid omhändertagande av patienter med snarkning och obstruktionsproblematik är det viktigt att beakta alla grader av andningsstörning. Nuvarande utredningsmetoder är väl lämpade för att diagnostisera avancerade sjukdomstillstånd präglade av andningsuppehåll under sömnen (apnéer) men har svårare att identifiera patienter vilkas andnings- och sömnstörning är mindre uttaladSleep-related partial upper airway obstruction may cause increased morbidity and mortality, but diagnosis and treatment of patients is varying and inconsistent. The present studies were aimed to evaluate presently applied indirect methods for assessing respiratory ventilation and to investigate the value and accuracy in estimating upper airway resistance during sleep by measuring intrathoracic pre
Return migration is an important phenomenon that involves a large share of all migrants, and has great potential for the enhancement of economic development, for instance through remittances and investments by migrants who are still abroad, and “brain gain” when migrants return with working experience from their former host countries. This paper deals with return migration, by refugee immigrants a

This paper presents a pilot study of an on-going doctoral study, addressing the knowledge, attitudes and practices of e-resources users. The study was a cross-sectional survey of graduate students, researchers, academic staff, heads of departments and college librarians at the Makerere University School of Public Health. The purpose was to test data collection methods and gain pre-understanding of
Study of Bergman's sarcastic handling of lecherous doctors and evil social workers in a series of films spanning from 1949 to 2000.
