Facets and Typed Relations as Tools for Reasoning Processes in Information Retrieval
Faceted arrangement of entities and typed relations for representing
different associations between the entities are established tools in knowledge
representation. In this paper, a proposal is being discussed combining both
tools to draw inferences along relational paths. This approach may yield new
benefit for information retrieval processes, especially when modeled for
heterogeneous environments in the Semantic Web. Faceted arrangement can be used
as a se-lection tool for the semantic knowledge modeled within the knowledge
repre-sentation. Typed relations between the entities of different facets can
be used as restrictions for selecting them across the facets

Profiling Phospholipids within Atlantic Salmon Salmo salar with Regards to a Novel Terrestrial Omega-3 Oil Source
The development and inclusion of novel oils derived from genetically modified (GM) oilseeds into aquafeeds, to supplement and supplant current terrestrial oilseeds, as well as fish oils, warrants a more thorough investigation into lipid biochemical alterations within finfish species, such as Atlantic salmon. Five tissues were examined across two harvesting timepoints to establish whether lipid isomeric alterations could be detected between a standard commercial diet versus a diet that incorporated the long-chain polyunsaturated fatty acids (LC-PUFA), EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid), derived from the GM oilseed Camelina sativa. Tissue-dependent trends were detected, indicating that certain organs, such as the brain, have a basal limit to LC-PUFA incorporation, though enrichment of these fatty acids is possible. Lipid acyl alterations, as well as putative stereospecific numbering (sn) isomer alterations, were also detected, providing evidence that GM oils may modify lipid structure, with lipids of interest providing a set of targeted markers by which lipid alterations can be monitored across various novel diets
Optical characterisation of polymeric nanocomposites using tomographic, spectroscopic and Fraunhofer wavefront assessment
Polymers are often embedded with specific nanofillers such that the functional characteristics and properties of the
resulting polymeric nanocomposite (PNC) are enhanced. The degree to which these enhancements can be achieved
depends not only on the level of particle loading of nanofillers, but most importantly on the resulting dispersion profile
achieved within the matrix. Agglomeration (often referred to as clustering) is a result of the mixing process and very
much depends on the chemistry between the polymer and nanofiller. Depending on the PNC type, different mixing
processes can be applied but the general consensus is that such processes are not repeatable themselves. Not only it is
quite difficult to achieve the desired level of dispersion, but in addition there is a limited number of characterization tools
that can be employed to routinely check the homogeneity achieved within a produced sample. Transmission electron
microscopy (TEM) and X-ray diffraction (XRD) techniques are usually employed, but they are very time consuming,
expensive, require special sample preparation and treatment, often produce results that are difficult to interpret and can
only analyse very small areas of sample. This work reports on the adaptation and development and three optical
techniques that are non-destructive, can accurately characterize the dispersion achieved as a result of the mixing process
and can analyse larger material areas. The techniques reported are based on static and dynamic visible and infra-red light
