First Time

In this article, the framework and architecture of a Subsurface Camera (SAMERA) are envisioned and described for the first time. A SAMERA is a geophysical sensor network that senses and processes geophysical sensor signals and computes a 3D subsurface image in situ in real time. The basic mechanism is geophysical waves propagating/reflected/refracted through subsurface enter a network of geophysical sensors, where a 2D or 3D image is computed and recorded; control software may be connected to this network to allow view of the 2D/3D image and adjustment of settings such as resolution, filter, regularization, and other algorithm parameters. System prototypes based on seismic imaging have been designed. SAMERA technology is envisioned as a game changer to transform many subsurface survey and monitoring applications, including oil/gas exploration and production, subsurface infrastructures and homeland security, wastewater and CO2 sequestration, and earthquake and volcano hazard monitoring. System prototypes for seismic imaging have been built. Creating SAMERA requires interdisciplinary collaboration and the transformation of sensor networks, signal processing, distributed computing, and geophysical imaging.

AbstractThis paper outlines recent developments in regional cooperation within the Gulf of Guinea region leading to the recent establishment of the Gulf of Guinea Commission. The huge interest generated among the major oil-producing multinational corporations, the newer independent producers and the participating States in the Gulf of Guinea necessitates a critical assessment of the Treaty Establishing the Gulf of Guinea Commission. This paper adopts a comparative analysis with pre-existing regional and institutional bodies having similar aims and objectives. The aim is to ascertain whether and to what extent the emergent regime can facilitate a sustainable and responsive regime for the anticipated explosion of exploitative activities in this resource-rich and strategic littoral zone. This paper, thus, places the existing regime in the context of international best practices for multinationals and governments involved in oil and gas exploration and production. The author identifies certain imperatives for the consideration of both the corporate and sovereign interests in the world's newest resource Eldorado.

The Native Title Act 1993 (NTA) introduces a new dimension to Australia's land tenure systems; new property rights are established for native title parties via the creation of a 'right to negotiate' (RTN) with respect to future acts on land where native title might be determined. There is growing recognition that, legal uncertainties about the potential co-existence of native title on pastoral leases aside, there are elements of the NTA that are resulting in sub-optimal outcomes for the petroleum industry. Within a Coasian analytical framework it is demonstrated that owing to unclear property rights, transactions costs for negotiating exploration and production with native title parties are high. Recognising this, the Commonwealth government has proposed a package of amendments that attempt to address industry concerns while balancing these against indigenous interests. These recommendations include a once-only RTN, a higher threshold for registration of claims, automatic renewal of existing production leases and mandatory statutory functions for Native Title Representative Bodies (NTRBs) that will require them to resolve competing native title claims and to sign-off agreements with resource developers. Noting that strategic behaviour by industry, indigenous parties and especially State governments have hampered effective operations of the NTA, the paper ends by considering the choices available to the petroleum industry to ensure that statutory amendments are in its best interests.

Primary Electrons

The physical foundations for the use of electron energy loss spectroscopy towards analytical purposes, seem now rather well established and have been extensively discussed through recent publications. In this brief review we intend only to mention most recent developments in this field, which became available to our knowledge. We derive also some lines of discussion to define more clearly the limits of this analytical technique in materials science problems.The spectral information carried in both low ( 0<ΔE<100eV ) and high ( >100eV ) energy regions of the loss spectrum, is capable to provide quantitative results. Spectrometers have therefore been designed to work with all kinds of electron microscopes and to cover large energy ranges for the detection of inelastically scattered electrons (for instance the L-edge of molybdenum at 2500eV has been measured by van Zuylen with primary electrons of 80 kV). It is rather easy to fix a post-specimen magnetic optics on a STEM, but Crewe has recently underlined that great care should be devoted to optimize the collecting power and the energy resolution of the whole system.

At the light microscope level the recent developments and interest in antibody technology have permitted the localization of certain non-microtubule proteins within the mitotic spindle, e.g., calmodulin, actin, intermediate filaments, protein kinases and various microtubule associated proteins. Also, the use of fluorescent probes like chlorotetracycline suggest the presence of membranes in the spindle. Localization of non-microtubule structures in the spindle at the EM level has been less rewarding. Some mitosis researchers, e.g., Rarer, have maintained that actin is involved in mitosis movements though the bulk of evidence argues against this interpretation. Others suggest that a microtrabecular network such as found in chromatophore granule movement might be a possible force generator but there is little evidence for or against this view. At the level of regulation of spindle function, Harris and more recently Hepler have argued for the importance of studying spindle membranes. Hepler also believes that membranes might play a structural or mechanical role in moving chromosomes.

In recent developments, the ASU HB5 has been modified so that the timing, positioning, and scanning of the finely focused electron probe can be entirely controlled by a host computer. This made the asynchronized handshake possible between the HB5 STEM and the image processing system which consists of host computer (PDP 11/34), DeAnza image processor (IP 5000) which is interfaced with a low-light level TV camera, array processor (AP 400) and various peripheral devices. This greatly facilitates the pattern recognition technique initiated by Monosmith and Cowley. Software called NANHB5 is under development which, instead of employing a set of photo-diodes to detect strong spots on a TV screen, uses various software techniques including on-line fast Fourier transform (FFT) to recognize patterns of greater complexity, taking advantage of the sophistication of our image processing system and the flexibility of computer software.

Twist Boundaries

Recent developments in specimen preparation, imaging and image analysis together permit the experimental determination of the atomic structure of certain, simple grain boundaries in metals such as gold. Single crystal, ∼125Å thick, (110) oriented gold films are vapor deposited onto ∼3000Å of epitaxial silver on (110) oriented cut and polished rock salt substrates. Bicrystal gold films are then made by first removing the silver coated substrate and placing in contact two suitably misoriented pieces of the gold film on a gold grid. Controlled heating in a hot stage first produces twist boundaries which then migrate, so reducing the grain boundary area, to give mixed boundaries and finally tilt boundaries perpendicular to the foil. These specimens are well suited to investigation by high resolution transmission electron microscopy.
