1. Ecology and evolution of coastal Baltic Sea 'dead zone' sediments
Abstract : Since industrialization and the release of agricultural fertilizers began, coastal and open waters of the Baltic Sea have been loaded with nutrients. This has increased the growth of algal blooms and because a portion of the algal organic matter sinks to the sea floor, hypoxia has increased. READ MORE

2. Excessive Seas : Waste Ecologies of Eutrophication
Abstract : This dissertation researches how perspectives in western industrial societies communicate about and give meaning to environmental degradation through case studies on the causes and effects of cultural eutrophication—namely nutrient pollution, algal blooms, and dead zones—in the Baltic Sea. Utilizing this approach, this dissertation addresses the ecological problems of cultural eutrophication in marine ecosystems by exposing normative claims humans make about the Baltic Sea and its contents as well as detailing how seas that exceed human expectations may offer insights into negotiating differing perspectives, discrepancies in power, and ways of being among humans and non-humans in marine environments.

3. Tools for protective lung ventilation. The elastic pressure-volume curve and aspiration of dead space
Abstract : Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. READ MORE

4. Phytoplankton and bacterioplankton dynamics in a polymictic tropical lake
Abstract : Phytoplankton and bacterioplankton dynamics in lakes are regulated by a multitude of factors such as light, temperature, water column mixing, nutrients, organic substrates, grazing, and food web structure. Tropical lakes are especially interesting to study because of the relative constancy of several of these factors. READ MORE

5. Turbulence-Assisted Planetary Growth : Hydrodynamical Simulations of Accretion Disks and Planet Formation
Abstract : The current paradigm in planet formation theory is developed around a hierarquical growth of solid bodies, from interstellar dust grains to rocky planetary cores. A particularly difficult phase in the process is the growth from meter-size boulders to planetary embryos of the size of our Moon or Mars. READ MORE
