Research of the corrosion resistance of experimental steel alloys in a seawater environment for the construction of ballast tanks on board of merchant navy vessels
Abstract
The degree of corrosion in ballast tanks on board of merchant navy vessels is very variable and influenced by the chemical composition and crystal structure of the alloy used. This project will determine in an experimental way the differences between the steel alloys used on board and some experimental steel compositions. The conclusions will be used for the development of a new steel alloy that is more resistant to the aggressive seawater environment in ballast tanks. The project is build on fysico-chemical measurements and automated image evaluation of the microscopic structures.Researcher(s)

Follow-up study of chemical, microbial and metallurgic factors affecting the corrosion in ballast tanks on board of merchant navy vessels
Abstract
Corrosion in ballast tanks is a very specific issue, influenced by numerous circumstances. As a consequence, many types of corrosion exist, each having its own influences and mechanisms. The project is divided in 3 work packages. First, on board sampling will be done. Chemical parameters and metallurgic characteristics of the ships will be identified. Based thereupon, a set of hypotheses regarding the cause of corrosion will be constructed, with the help of multivariate statistics. These will then be tested in an experimental setup.Researcher(s)

Construction of a soil bioreactor for degradation of the gaseous pollutant sulfur hexafluoride
Abstract
Sulfur hexafluoride (SF6) is a strong greenhouse gas that occurs in albeit low concentrations in the atmosphere. A useful method for the degradation of this gas is so far not known. In this project we construct a reactor to test the capacity of different polluted soils to break down SF6. In parallel, we determine different physical and chemical parameters of the soils during SF6 treatment.Researcher(s)

Phytotechnical use of bamboo for biomass production and soil sanitation.
Abstract
The aim of this project is to evaluate the use of bamboo plants in biomass production and soil sanitation. Plants will be grown on three different fields and will thus exposed to different levels of pollution. Assessment of biomass production and tolerance towards the pollutant includes growth analysis, carbon assimilation and chlorophyll fluorescence. Based upon these data, an existing growth model (FORUG) will be parametrised for bamboo.Researcher(s)

Study of chemical and microbial factors affecting the corrosion in ballast tanks on board of merchant navy vessels.
Abstract
Corrosion in ballast tanks is a very specific issue, influenced by numerous circumstances. As a consequence, many types of corrosion exist, each having its own influences and mechanisms. The project is divided in 3 work packages. Te first package intends to formulate a protocol for survey, a data form and a do it yourself kit for sampling. During the second package, on board sampling will be done. Chemical parameters and microbiological consortia will be identified. The third package tends to formulate a hypothesis regarding the cause of corrosion with the help of multivariate statistics.Researcher(s)

Role of auxin in the induction of stress-induced somatic embryogenesis.
Abstract
Previous research indicated that a mild stress treatment stimulates isolated plant cells to dedifferentiate and to transform into somatic embryos, and this through an interaction with auxin and auxin metabolism. This project uses Arabidopsis mutants in hormone metabolism and stress responsiveness to investigate this interaction further.Researcher(s)

Redox status of plant cells after exposure to cadmium : a comparison between cellular defence, toxicity and tolerance mechanisms.
Abstract
In this project plant cell cultures as well as whole Arabidopsis plants are chronically exposed to low Cd concentrations and the effect studied using physiological and biochemical techniques (e.g. measurements of ascorbate/dehydroascorbate, etc...). Also the effect on the development of whole plants from the seed are studied with physological and biochemical tools as well as the morphological impact. In another part the effect of Cd challenge on the changing proteome is studied.Researcher(s)

Functional genetic analysis of ascorbate and glutathione-mediated growth regulation in Physcomitrella patens.
Abstract
In this project we want to set up a model system for both physiological and molecular purposes and use Physcomitrella for a functional genetic analysis of the regulation of the physiology of cell division and elangation by ASC and GSH.Researcher(s)

The role of photorespiration in heavy metal adaptation.
Abstract
Preliminary data from a genetic analysis point at an increased photorespiratory activity in tomato plants treated with a low dosage of cadmium. To confirm of contradict th is hypothesis, we will study photosynthesis, phÇ)torespiration, anti-xenobiotic defences (glutathione and phytochelatins) in intact plants, or through a combination of biochemical and molecular techniques, in function of cadmium stress.Researcher(s)

Ascorbate mediated control of cell cycle and redox state in plant cells.
Abstract
Due to its antioxidant properties, ascorbate (Asc) has a crucial function in the plant cell defence agains oxidative processes. Asc and its oxidised counterpart dehydroascorbate (DHA) are shown to be involved in the regulation of cell division and cell elongation. The ratio between Asc and DHA might be a link of great importance between these phenomena. The nature of this link, and the effect the Asc redox state might have on the plant cell physiology, is the subject of this research.Researcher(s)
