F or the reader who uses technology numbers all day, the topic of information and communication technology (ICT) rankings and performance indices might seem a bit over the top. Yet, many might not be aware of the amazing variety of detailed, high-quality ICT measurements and analyses — especially telecom-related statistics, charts, and graphs — available. These measurements come in many forms: ...

The market for bone grafts continues to be ever-expanding in products, device categories, and volumes applied. Market analysts consistently see bone graft substitutes as an investment opportunity, quoting our increasingly aging and sicker population and apparent disenchantment with the gold standard— mainly iliac crest graft—as the leading driver for this ongoing development. Spine surgery, and...

SOLAR SIC GRAIN OF TYPE X. E. Zinner, M. Jadhav, F. Gyngard, and L. R. Nittler. Laboratory for Space Sciences and Physics Deparment, Washington University, St. Louis, MO, USA. E-mail: [email protected] Department of Terrestrial Magnetism, Carnegie Institution, Washington, DC, USA. Introduction: Among presolar SiC grains from the LU fraction of the Murchison L separation series [1, 2], we identified...

There are two kinds of chlorites occurred in Anshan area, among which the hydrothermal Fe-chlorite with longer Fe-OH wavelength is spatially related to high-grade magnetite ore, meaning that mapping can be used target BIF-hosted high grade iron ore. In this article, quadratic polynomial, cubic spline, and quartic polynomial method were interpolate absorption near 2250 nm China ZY1-02D satellite...

Industrialization has historically been synonymous with development, while deindustrialization is a well-established trend in mature developed economies as they move towards services-based economies. Yet recent trends show that many developing countries – especially in Africa and Latin America – have witnessed their shares of manufacturing employment and output shrinking long before they have a...

Water encounters various resistances in moving along a path of decreasing potential energy from the soil through the plant to the atmosphere. The reported relative magnitudes of these pathway resistances vary widely and often these results are conflicting. One reason for such inconsistency is the difficulty in measuring the potential drop across various segments of the soil-plant-atmosphere con...

Synthetic aperture radar (SAR) data were acquired over Bonanza Creek Experimental Forest (Alaska) in March 1988 under thawed and frozen conditions. For h e stands analyzed, Cband backscatter at 4 2 O 4 5 " lacidence angle was 2.7-6.9 dB smaller under frozen than under thawed conditions for white spruce and balsam poplar, with the largest difference at HV and the smallest at EM polarization. The...
