In order to be able to draw inferences about real world phenomena from a representation expressed in a digital computer, it is essential that the representation should have a rigorously correct algebraic structure. It is also desirable that the underlying algebra be familiar, and provide a close modelling of those phenomena. The fundamental problem(More)
Recently we demonstrated that a member of the neuregulin-1 (NRG-1) family of growth factors is a mitogen and survival factor for olfactory ensheathing cells (OECs). OECs are specialized glial cells within the olfactory system that are believed to play a role in the continual nerve re-growth of this tissue. OECs share properties with both astrocytes and(More)
The olfactory ensheathing cell (OEC) is a unique glial cell able to support neurite outgrowth in the CNS throughout life. The OEC has been described as having both Schwann cell-like and astrocyte-like characteristics. The purpose of this study was to compare gap junctional communication and connexin (Cx) expression in cultured olfactory ensheathing cells(More)
In the search for a rigorous closed algebra for the query and manipulation of the representations of spatial objects, most research, apart from a few exceptions, has focused on defining and refining the mathematical model, whereby the representation is assumed to be defined by real-numbered coordinates in 2D or 3D space. The realization of this theory in(More)

The purpose of this talk is to discuss an implicit numerical method for the solution of a class of Stefan problems. The method is efficient in the sense that, although the location of the moving boundary is determined by solving a sequence of problems, the amount of computation done to advance the solution one time step is little more than would be required(More)
SUMMARY The Land Administration Domain Model (ISO 19152) (ISO-TC211 2012) defines a specific geometry form which allows the clean and simple mixing of 3D cadastral objects such as volumetric parcels with the more common 2D parcels. It does this by introducing a concept of boundary surfaces, known as " face strings ". The unbounded nature in the vertical(More)
