Every year the Brazilian sugarcane industry generates up to 10 million tons (dry matter) of ash from the combustion of sugarcane bagasse, which is a fibrous plant material that remains after sugarcane juice extraction. Bagasse ash is alkaline and contains minerals, including phosphorus (P) and potassium (K). [...]

Photosystem I (PSI) from the thermophilic cyanobacterium Thermosynechococcus elongatus is a membrane-bound, multipigment protein supercomplex. It converts light to electrochemical energy with a quantum efficiency of almost 100 %. [...]

Vegetation plays an important role in the hydrological cycle, as it governs the partitioning of water fluxes and therewith affects the functioning of the system. Deforestation can cause a highly non-linear response of the natural system and may change the interaction between the land surface and the atmosphere, flow conditions, groundwater recharge and soil moisture storage, which in turn affects the quality and amount of available water resources [...]

A future European energy system that primarily relies on variable renewable energy sources (VRES) such as wind turbines and photo-voltaic (PV) modules is becoming increasingly conceivable. Nevertheless, the role that VRES could play in future energy systems is still uncertain. [...]

The principle of detailed balance forms the basis of the present thesis. It states that all microscopic processes in thermodynamic equilibrium are equal to their respective counter processes [...]

AD is a neurodegenerative disorder leading to brain atrophy and severe dementia. Thirtyfive million people are affected worldwide and the number is rapidly increasing. [...]
