Abstract: A wind turbine includes a hub, at least one blade and at least one pitch bearing to connect the at least one blade to the hub. The at least one pitch bearing has at least an inner ring and an outer ring, and at least a rolling race. The wind turbine further includes at least a tensioning system configured to exert a radial compression force to at least a part of the outer ring of the at least one pitch bearing, thus increasing the resultant stiffness of the at least one pitch bearing.

Abstract: Wind turbine comprising at least a pitch bearing comprising at least two rings, each of the at least two rings attached to a wind turbine component, being a first wind turbine component a blade and a second wind turbine component a hub, and further comprising at least one bearing reinforcement attached to at least one of the two rings. The invention also relates to the pitch bearing of the wind turbine.

Abstract: The present invention relates to methods for producing polyketide synthase variants, and for altering the activity and/or substrate specificity of putative native and variant polyketide synthases. The present invention further relates to compositions comprising said polyketide synthase variants, compounds prepared using said polyketide synthase variants, and uses of said polyketide synthase variants. In one embodiment, said polyketide synthase variant is 2-pyrone synthase.

Abstract: The present invention relates to a portable electric generator comprising a heating plate and cooling means between which there is arranged at least one thermoelectric plate where the electric current generated between the heating plate and the cooling means when the plate is at a temperature greater than that of the cooling means is collected, a potential difference being established as a result.

Abstract: Methods for identifying strains of bacteria, particularly methods for serotyping Streptococcus pneumoniae in a sample, methods for detecting and/or classifying S. pneumoniae infection by serotype, array devices and kits for use in such methods are disclosed. Array devices comprise a set of capture antibodies immobilised on a substrate at pre-determined array positions, wherein the set of capture antibodies comprises serotype-distinguishing antibodies which differ in their binding specificity for different S. pneumoniae serotypes. Serotyping methods may employ whole cell detection utilising one or more detectable labels, including in situ labelling of array-bound cells.
