N. Ó Murchadha** Physics Department University College Cork Cork, Ireland Fax: +353-21-276949, E-mail: [email protected] Abstract In this article we show that one can construct initial data for the Einstein equations which satisfy the vacuum constraints. This initial data is defined on a manifold with topology R with a regular center and is asymptotically flat. Further, this initial data will...

Dolores Dooley Clarke describes how the course in medical ethics at University College, Cork is structured, how it has changed and how it is likely to change as time goes on. Originally, the students seemed to view it as an intrusion 'to be tolerated' in their programme of 'strictly medical' studies. However, having moved on from that and away from the lecturer always being a Roman Catholic pri...

Agglomerated cork composites production has been arising as an alternative eco-friendly to stoppers use and attracts interest create sustainable products materials. A cork-bamboo-latex composite was developed by compression-molding the interaction between three interfaces well their mechanical properties were evaluated density measure, immersion test, FTIR, compression microbial analysis aiming...

Composites are used in a wide range of engineering applications, as result, exposure to hostile environments is rather common and its mechanical properties degradation unavoidable. It necessary have complete understanding the impact on performance, namely critical solicitations low velocity impacts. Therefore, this work intends analyse response carbon fibre/epoxy composite, similar architecture...

systems possess can serve both as havens for bacterial colonization and portals for the extension of endodontic disease. Figure 1 is a cone beam computed tomography (CBCT) rendering of a lateral lesion of endodontic origin. As usual, the portal of exit from this diseased pulpal system is found in the center of the lesion. Many have documented the vast array of anatomical possibilities of pulpal...

Cork granules (Quercus suber L.) were slowly pyrolyzed at temperatures between 400-700 °C and under N2 flow. While preserving its structure, some cells of the cork biochar became interconnected, allowing such carbon residue to be used as templates for manufacturing ceria redox materials. The pyrolytic char morphology was similar that natural precursor. produced belonged Class 1 (C > 60%) pos...

Suppose that X,X′ are simply-connected closed exotic 4-manifolds. It is well-known X′ obtained by an order 2 cork twist of X. We give infinite family 4-manifolds not generated any cork. This the first example admitting such a condition. prove necessary condition 4-dimensional Ozsváth-Szabó invariants for to be and as application non-contractible relatively never induced Furthermore, we estimate...
