21. Regulation of protein synthesis in eukaryotes : control of elongation factor 2 phosphorylation
Sammanfattning : .... LÄS MER
22. The genetics of antibiotic production and the role of antibiotics in biological control of Erwinia amylovora by Erwinia herbicola
Sammanfattning : Erwinia herbicola is an epiphyte of apple and pear with potential as a biocontrol agent of Erwinia amylovora, which causes fire blight. This research aimed to assess the relative role of antibiotics produced by E. herbicola, Eh318 as a mechanistic basis for biocontrol. LÄS MER
23. Get in tune : chloroplast and nucleus harmony
Sammanfattning : Photosynthetic eukaryots emerged as a result of several billion years of evolution between proeukaryotic cell and ancestral cyanobacteria that formed modern chloroplasts. The symbiotic relationship led to significant rearrangements in the genomes of the plastid and the nucleus: as many as 90 % of all the plastid genes were transferred to the nucleus. LÄS MER
24. Urban water management : Modelling, simulation and control of the activated sludge process
Sammanfattning : During the last few decades, wastewater treatment processes in urban water management have become more and more efficient and complex. Several factors such as urbanization, stricter legislations on effluent quality, economics, increased knowledge of the involved biological, chemical and physical processes as well as technical achievements have been important incentives for the development of more efficient procedures for wastewater treatment plants.

25. Externally positive systems : Analysis and control based on combinatorial polynomials
Sammanfattning : Monotonic tracking is required in many control systems, including those that cannot tolerate any overshoots and undershoots in their closed-loop responses. Classical examples are found in vehicle cruise control and liquid tank level control. LÄS MER
