16. Directional aggressive pulse sounds in the bottlenose dolphin (Tursiops Truncatus) : technical aspects and social implications
Sammanfattning : The ability of dolphins to produce pulse sounds with a bandwidth of up to 150 kHz, has been intensively studied with focus on their sonar capabilities, i.e. the detection, ranging and discrimination of objects of various shapes, textures and material. LÄS MER
17. Molecular methods in malaria control in the era of pre-elimination
Sammanfattning : Increased funding combined with effective malaria control methods for prevention, diagnosis, and treatment, has resulted in a 30% reduction of the global malaria burden over the last decade. As malaria prevalence declines in areas of successful malaria control, the proportion of subpatent infections that fall below the detection level of malaria rapid diagnostic tests (RDTs) and microscopy increases.

18. Plants as Sources of Natural and Effective Acaricides : Against Ixodes ricinus (Acari: Ixodidae)
Sammanfattning : Ticks and tick-borne diseases are major health hazards worldwide, with increasing numbers of cases of Lyme disease and tick-borne encephalitis reported yearly. Meanwhile, concerns about the environmental impact and safety of chemical acaricides are driving research into alternative control methods, such as plant-based acaricides. LÄS MER
19. Control of Voltage Source Converters for Voltage Dip Mitigation in Shunt and Series Configurations
Sammanfattning : Custom Power is the application of power electronics to improve the quality of power distribution for sensitive industrial plants. Industries reporting production stops due to voltage disturbances, like short interruptions and voltage dips, include paper mills, semiconductors facilities and other industries with fully automated production.

20. Functional Layer-by-Layer films and aerogels of cellulose nanofibrils
Sammanfattning : This thesis deals with the preparation of functional Layer-by-Layer (LbL) films of cellulose nanofibrils (CNFs) and polyelectrolytes. LbL films ranging in thickness from 10 nm to 5 μm were deposited onto both solid surfaces and porous nanocellulose aerogels in order to prepare functional surfaces and materials. LÄS MER
