(Elsevier, 2007-02)Normal faults contained in multilayers are often characterised by dip refraction which is generally attributed to differences in the mechanical properties of the layers, sometimes leading to different modes of fracture. ...
-
(Elsevier, 2009-02)Empirical rock properties and continuum mechanics provide a basis for defining relationships between a variety of mechanical properties, such as strength, friction angle, Young’s modulus, Poisson’s ratio, on the one hand ...
-
(American Geophysical Union, 2007)The growth of normal faults in periodically layered sequences with varying strength contrast and at varying confining pressure is modeled using the Distinct Element Method. The normal faulting models are comprised of strong ...
-
(Elsevier, 2006-05)Existing conceptual growth models for faults in layered sequences suggest that faults first localise in strong, and brittle, layers and are later linked in weak, and ductile, layers. We use the Discrete Element Method (DEM) ...

(2009-09)This is the second year in which a team from University College Dublin has participated in the Multi Agent Contest. This paper describes the system that was created to participate in the contest, along with observations ...

(The Geological Society of America, 2007-11)The Pb isotopic composition of detrital K-feldspar grains can be rapidly measured using laser ablation MC-ICPMS. The feldspar Pb signal can survive weathering, transport and diagenesis, and careful targeting avoids problems ...
-
(John Wiley and Sons, 2009-11)Sandstone provenance studies can help constrain palaeogeographic reconstructions and ancient drainage system scales and pathways. However, these insights can be obscured by difficulties in geochemically distinguishing or ...

(Elsevier, 2009-11-20)Thromboxane plays an essential role in haemostasis, regulating platelet aggregation and vessel tone. In humans, it signals through the TPalpha and TPbeta isoforms that are transcriptionally regulated by distinct promoters, ...
-
(Elsevier, 2006-04-28)The human thromboxane (TX)A2 receptor (TP) gene encodes two TP isoforms, TPalpha and TP beta that are regulated by distinct promoters designated promoter (Prm) 1 and Prm3, respectively. Previous studies established that ...

(Elsevier, 2001-05-28)Both thromboxane (TX) A2 and 8-epi prostaglandin (PG) F2alpha have been reported to stimulate mitogenesis of vascular smooth muscle (SM) in a number of species. However, TXA2 and 8-epiPGF2alpha mediated mitogenic signalling ...
