Service-oriented models for audiovisual content storage
No full textWhat are the important topics to understand if involved with storage services to hold digital audiovisual content? This report takes a look at how content is created and moves into and out of storage; the storage service value networks and architectures found now and expected in the future; what sort of data transfer is expected to and from an audiovisual archive; what transfer protocols to use; and a summary of security and interface issues
The preparation of C-3 building blocks and their use in heterocyclic synthesis
No full textThis work concerns the investigation of new synthetic routes to heterocycles via a building block strategy. Three classes of heterocycle are targeted - pyrimidines, pyrazoles and isoxazoles. These classes cover both five- and six-membered ring systems and are representative of a much wider range of target molecules, having possible bioactivity. All three classes of heterocycle can also be produced from the same type of building block by altering the nature of the bisnucleophile used to close the ring (a 2- or 3-atom unit).The building blocks employed contain a 1,3-dicarbonyl structure with a protected carbonyl group at the 2-position. The first building blocks prepared have a protected ester by way of a ketene dithioacetal. The reduction of this group (by dissolving metal) leads to a dithiane, equivalent to a formyl group. Both the ketene dithioacetals and the dithianes are subsequently cyclised to the five- and six-membered heterocycles. Ketene dithioacetal building blocks generate heterocycles that bear a novel mercapto thioether side chain. Building blocks based on dithianes show complex cyclisation patterns by offering multiple reaction sites.The incorporation of fluorine into this class of building block proved to be troublesome so attention was focused on the use of vinyl ethers and enamines as masked formyl equivalents. By adapting the work of Schreiber and developing a novel procedure to form fluorinated building blocks, it is possible to isolate three heterocyclic precursors - a bis(trifluoroacetyl)-and mono)trifluoroacetyl)-enamine and an analogous compound containing a dithiane-masked formyl unit. These building blocks have then been converted into all three classes of heterocycle described earlier.By comparing the data of molecules generated by this route with those in recent literature it is possible to gain a much more complete view of the cyclisation processes. For example, many of the building blocks used in this work contain more than two sites for reaction which lead to complex mechanistic possibilities which can be rationalised.The initial objective of merging an intrinsically bioactive molecule (the classes of heterocycle chosen) with a bioactive enhancer (the inclusion of fluorine into these molecules) has proven successful.</p
AC-6-U.S. Naval Planes Flying in Formation, Langley Field, VA/Thank-You Card from Stephen Tury to the Hungarian Defense Council.
No full textThis postcard, which depicts U.S. Naval planes flying in formation, was sent to the Hungarian Defense Council by Private Stephen Tury. The Council was organized in New Brunswick by leaders of local Hungarian churches and societies. During the Second World War it sent supplies, such as the carton of cigarettes Tury is thanking it for, to members of the military of Hungarian descent from the New Brunswick area
