OBJECTIVE To assess the results of an upper pole nephrectomy technique on 5 children. MATERIALS AND METHODS Upper pole nephrectomy was performed on 5 children, including 4 females and 1 male. Age ranged from 3 to 6 years old. The technique was performed without initial dissection of the renal pedicle. The upper pole is incised and removed. Upon its complete dissection, the segment that drains...

The concept of a pole-sitter has been under investigation for many years, showing the capability low-thrust propulsion system to maintain spacecraft at static position along planet’s polar axis. From such position, view regions equivalent that low- and mid-latitudes from geostationary orbit. Previous work hinted existence pole-sitters would only require solar sail provide necessary propulsive t...

We describe the first combined variability-proper motion survey for QSOs on Schmidt plates. 85 Tautenburg Schmidt plates covering about 9 square degrees near the north Galactic pole were digitised by means of the APM facility in Cambridge. Variability indices have been derived from U and B data, both with a time-baseline of three decades. Structure function analysis has been applied to search f...

Polar mesospheric clouds (PMCs) were observed by a ground-based Fe Boltzmann temperature lidar for 65 h on 17-19 and 24-26 January 2000 above the geographic South Pole. The mean PMC backscatter ratio, volume backscatter coetficient, total backscatter coetficient, layer centroid altitude, and layer rms width are 53.5, 2.9x10 -9 m-Xsr -x, 4.3x10 -6 sr -x, 85.37 km, and 0.78 km, respectively. Stro...

The rapid crossing of the solar equatorial region by Ulysses as it returned from the south pole resulted in 7 crossings of the heliospheric current sheet between 10“S and 20”N and 10 distinct solar wind interaction regions between 18“S and 22”N. Both the extent of the current sheet and the latitude interval containing the interaction regions are a f~ctor of= 2 less than were observed by Ulysses...

The Mars Polar Lander (MPL) mission was the first planetary mission to use Internet-based distributed ground operations where scientists and engineers collaborate in daily mission operations from multiple geographically distributed locations via the Internet. This paper describes the operations system, the Web Interface for Telescience (WITS), which was used by the MPL mission for Internet-base...

[1] Although diverse measurements have indicated H, OH , or H2O species in the lunar polar regions, pinpointing its location, form, and abundance in specific reservoirs has proven elusive. Here we report on the first orbital radar measurements of Shackleton crater near the lunar south pole. Mini-RF observations indicate a patchy, heterogeneous enhancement in CPR (circular polarization ratio) on...

Surface and aircraft measurements show large amounts of reactive nitrogen over the Antarctic plateau during the ANTCI 2003 experiment. We make use of 1-D and 3-D chemical transport model simulations to analyze these measurements and assess the photochemical impact of snow NOx emissions. Boundary layer heights measured by SODAR at the South Pole were simulated reasonably well by the polar versio...
