Multichannel seismic-reflection data show that the Victoria Land-basin, unlike other sedimentary basins in the Ross Sea, includes a rift-depression 15 to 25 kilometers wide that parallels the Transantarctic Mountains and contains up to 12 kilometers of possible Paleozoic to Holocene age sedimentary rocks. An unconformity separates the previously identified(More)
We have investigated the localization of Kex1p, a type I transmembrane carboxypeptidase involved in precursor processing within the yeast secretory pathway. Indirect immunofluorescence demonstrated the presence of Kex1p in a punctate organelle resembling the yeast Golgi apparatus as identified by Kex2p and Sec7p (Franzusoff, A., K. Redding, J. Crosby, R. S.(More)
Address standards have been developed and are still being developed by a number of countries (e.g. and the Organization for the Advancement of Structured Information Standards. (OASIS)). More recently, these standards have tended to include geospatial components and to cater for other forms of service delivery and not just postal, such as goods delivery,(More)
The Internet has spawned the development of virtual communities or virtual social networks which generate and share information with one another, and with the public at large. Volunteered geographical information (VGI) refers to user-generated content that is made available as base data on public mapping websites or as third party data overlaid on virtual(More)
The Commission on Spatial Data Standards of the International Cartographic Association (ICA) is working on defining formal models and technical characteristics of Spatial Data Infrastructures (SDI). To date, this work has been restricted to the Enterprise and Information Viewpoints from the ISO Reference Model for Open Distributed Processing (RM-ODP)(More)
Addresses come in many forms as they have a variety of uses. In our paper we illustrate the need for standardized addresses in South Africa by describing scenarios where standardized addresses are required, or where standardized addresses would improve the current situation. We present the eleven address types described in the current draft South African(More)
1. Abstract The Commission on Spatial Data Standards of the International Cartographic Association (ICA) is working on defining formal models and technical characteristics of Spatial Data Infrastructures (SDI). The Commission has already presented models of the Enterprise and Information Viewpoints from the ISO Reference Model for Open Distributed(More)
International Cartographic Association (ICA) is working on defining models of spatial data infrastructures (SDI). SDI models from the enterprise and information viewpoints of the Reference Model for Open Distributed Processing (RM-ODP) have already been presented. Our model from the computational viewpoint identifies the main computational objects of an SDI(More)
Online social spaces have become very popular in the past couple of decades. With the great numbers of users in the online environments it becomes obvious that the human factor plays an important role in the social structure of such environments. In online virtual worlds such as Second Life one may encounter not only civil, but even criminal offenses such(More)
