Spatial rationalisation in multi-plant enterprisesRäumliche rationalisierung in mehrwerk-unternehmenRationalisation spatiale dans les entreprises à usines multiples     

H.D Watts 《Geoforum》1974,5(1):69-76

In an old established industrial area spatial rationalisation stratégies of multi-plant enterprises play an important role in modifying the location of industry. The special characteristics of the multiplant enterprise are set out, and the effects of organisational structure, socio-political environment, enterprise inter-action, and merger activity on industrial location is considered. Quantitative techniques available to management are reviewed, but it is shown there is little evidence to indicate they have been used. Three spatial rationalisation strategies are identified, each producing a different location pattern, although most multi-plant enterprises will adopt some form of strategy mix.  相似文献   

High frequency oscillations during magnetar flares     

Anna L. Watts  Tod E. Strohmayer 《Astrophysics and Space Science》2007,308(1-4):625-629

The recent discovery of high frequency oscillations during giant flares from the Soft Gamma Repeaters SGR 1806-20 and SGR 1900+14 may be the first direct detection of vibrations in a neutron star crust. If this interpretation is correct it offers a novel means of testing the neutron star equation of state, crustal breaking strain, and magnetic field configuration. We review the observational data on the magnetar oscillations, including new timing analysis of the SGR 1806-20 giant flare using data from the Ramaty High Energy Solar Spectroscopic Imager and the Rossi X-ray Timing Explorer. We discuss the implications for the study of neutron star structure and crust thickness, and outline areas for future investigation.   相似文献

Geochemistry and petrography of basalt grindstones from the Karak Plateau,central Jordan     

Brandon G. Watts  Marvin E. Bennett  Otto C. Kopp  Gerald L. Mattingly 《Geoarchaeology》2004,19(1):47-69

Seventeen basalt grindstone fragments from central Jordan's Karak Plateau were studied. Most of these artifacts are vesicular or amygdaloidal with calcite as the dominant mineral filling the voids. The major minerals are olivine (with iddingsite rims), plagioclase, clinopyroxene, magnetite, and apatite. Glass is present in some samples. One basalt fragment is quite different in appearance and composition and may have come from flows closer to the Dead Sea. Grindstone fragment compositions plot in the tephrite‐basanite and basalt fields. A plot of the concentrations of niobium, zirconium, and yttrium reveal that the sample compositions plot in the “within‐plate alkali basalt” and “within‐plate tholeiite” fields. The acquisition of basalts for preparing such implements appears to have been random. Some may have been introduced through trade and migration. Archaeological and environmental studies on the Karak Plateau are urgently needed because Jordan's population growth and economic development are destroying many sites and their environmental contexts. © 2004 Wiley Periodicals, Inc.  相似文献   

Future use of tritium in mapping pre-bomb groundwater volumes   总被引：2，自引：0，他引：2  

Eastoe CJ  Watts CJ  Ploughe M  Wright WE 《Ground water》2012,50(1):87-93

The tritium input to groundwater, represented as volume-weighted mean tritium concentrations in precipitation, has been close to constant in Tucson and Albuquerque since 1992, and the decrease in tritium concentrations at the tail end of the bomb tritium pulse has ceased. To determine the future usefulness of tritium measurements in southwestern North America, volume-weighted mean tritium levels in seasonal aggregate precipitation samples have been gathered from 26 sites. The averages range from 2 to 9 tritium units (TU). Tritium concentrations increase with site latitude, and possibly with distance from the coast and with site altitude, reflecting local ratios of combination of low-tritium moisture advected from the oceans with high-tritium moisture originating near the tropopause. Tritium used alone as a tool for mapping aquifer volumes containing only pre-bomb recharge to groundwater will become ambiguous when the tritium in precipitation at the end of the bomb tritium pulse decays to levels close to the analytical detection limit. At such a time, tritium in precipitation from the last one to two decades of the bomb pulse will become indistinguishable from pre-bomb recharge. The threshold of ambiguity has already arrived in coastal areas with a mean of 2 TU in precipitation and will follow in the next three decades throughout the study region. Where the mean tritium level is near 5 TU, the threshold will occur between 2025 and 2030, given a detection limit of 0.6 TU. Similar thresholds of ambiguity, with different local timing possible, apply globally.  相似文献
