Production of virus occlusion bodies that occlude virions comprising genomes of different species of baculoviruses that can be used to combat insect pests. A method is presented for the production of occlusion derived virions (ODVs) that simultaneously comprise genomes of different baculovirus species, occluded in a viral occlusion body (OB) with the structural and morphological features characteristic of baculoviruses. Mixed genome ODVs and OBs can be produced by co-infecting insect cells or insect hosts using two or more different baculoviruses species. Co-infection may be achieved by simultaneous inoculation of the different baculoviruses or with a time interval between inoculations, which results in different proportions of each species' genomes in the ODVs and OBs that are produced. The produced OBs can be used either directly for preparing an insecticide, or to infect susceptible insects to produce larger quantities of mixed genome ODVs and OBs, also useful for combating pest insects.

The representation of content, in a scene representation, is enriched with a view to the adaptive use of the latter according to a set of common parameters. A subgraph of the scene graph, which is suitable for variable processing, is identified. For this purpose, it is possible to define two new types of scene element one of which allows the identification of the subgraph and the second of which allows the set of common parameters to be imposed in conjunction with the subgraph. An example of the first type consists of a node of the so-called "AdaptivityControl" type which encompasses the entire subgraph, a list of the nodes describing the set of common parameters and a group of fields allowing a dynamic updating of the content of this node. An example of the second type consists of a node of the so-called "CompressedlmageStrategy" type which comprises information relating to the object to be coded and the parameters of the coding.

A process is presented which produces at least one block of dense material constituted by hard particles dispersed in a binder phase, it being possible for the dense material to be enriched locally with binder phase by imbibition. The process includes bringing at least one imbibition area of a surface of the block, preferably coated with a coating material, into contact with an imbibiting material which locally enriches the block with binder phase. The block in contact with the imbibiting material is then subjected to a suitable thermal cycle constituted by heating, temperature maintenance and cooling. This serves to bring some or all of the imbibiting material and the binder phase of the block into the liquid state in such a manner that the enrichment with binder phase takes place solely through the imbibition area. The block is used in connection with the building of a drill bit or tool.
