Geochronological and isotopic constraints on the Mesoproterozoic Namaqua–Natal Belt: evidence from deep borehole intersections in South Africa
, 2000
"... Mesoproterozoic lithologies of the Namaqua–Natal Belt are exposed in the west and east of South Africa but the central section of the belt is obscured by younger sedimentary cover. This belt is one of several Grenvillian-aged belts world-wide and is of importance in reconstructions of the Meso- to N ..."

- to Neo-Proterozoic supercontinent of Rodinia. Zircons from granite and biotite gneiss in two deep boreholes which penetrated the Phanerozoic cover provide SHRIMP U–Pb dates of 1053+29/−25 Ma and 1134+15/−15 Ma. Sm–Nd model dates for whole-rock samples from these and two other boreholes range from ∼2400
Teaching at the Intersections of Urban Communication and Public Place and Space
"... Interdisciplinary is a word that has been picked up by institutions of higher edu-cation, research foundations, and even popular culture as a way to articulate the need to move beyond the traditional disciplinary boundaries within which we cat-egorize knowledge about the world. While disciplinary si ..."

silos in higher education often reflect structures within which teaching and learning are engaged, we con-tend that critical pedagogy provides an opportunity for innovative thinking and creativity to emerge via Giroux’s (1981) critical notion of praxis. We discuss how Penny’s (2009) notion of deep
Fracture and fault systems characterising the intersection between the Lower
"... Abstract: The 2544 m deep geothermal well “RWTH-1”, drilled in 2004 in the city centre of Aachen, is located geologi-cally in a key position between the Variscan Ardennes-Rhenish Massif and the active rift zone of the Lower Rhine Embay-ment close to the early Palaeozoic London-Brabant Massif. The bo ..."

Contemporary Mathematics Intersection cohomology invariants of complex algebraic varieties
"... Abstract. In this note we use the deep BBDG decomposition theorem in order to give a new proof of the so-called “stratified multiplicative property” for certain intersection cohomology invariants of complex algebraic varieties. 1. ..."

ALTERATION AND DEEP FLUID SOURCES
"... State-of-the-art MT array measurements in contiguous bipole deployments across the Dixie Valley thermal area have been integrated with regional MT transect data and other evidence to address several basic geothermal goals. These include 1), resolve a fundamental structural ambiguity at the Dixie Val ..."

. The appended MT soundings help to substantiate a deep, subvertical conductor intersecting the base of Dixie Valley from the middle crust, which appears to be a hydrothermal conduit feeding from deep crustal magmatic underplating. This may supply at least part of the high temperature fluids and explain enhanced
RAY-TRACED COLLISION DETECTION FOR DEFORMABLE BODIES
"... This paper presents a new approach to collision detection and modeling between deformable volumetric bodies. It allows deep intersections while alleviating the difficulties of distance field update. A ray is shot from each surface vertex in the direction of the inward normal. A collision is detected ..."

The Hubble Deep Field-South QSO
, 1998
"... Abstract. The Hubble Deep Field-South was chosen to have a QSO (RA 22:33:37.6 Dec −60:33:29 J2000 and B=17.5) in the field to allow for studies of absorption systems intersecting the sight line to the QSO. To assist in the planning of HDF-S observations we present here a ground-based spectrum of the ..."

Intersecting Sets: A Basic Abstraction for Asynchronous Agreement Problems

This paper introduces a basic and particularly simple distributed computing abstraction suited to asynchronous distributed agreement problems. This a ..."

Image-based Collision Detection and Response between Arbitrary Volume Objects
"... We present a new image-based method to process contacts between objects bounded by triangular surfaces. Unlike previous methods, it relies on image-based volume minimization, which eliminates complex geometrical computations and robustly handles deep intersections. The surfaces are rasterized in thr ..."
