Of geographic location

In the United States, kaolin is the principal clay product and about 9 million metric tons were reported mined and processed during 1991 (25). Bentonite production was reported as being 2 million tons for the same year. World production data for clays, often as a function of geographical location, use, or specific producer, are available (26). 

Organisms assigned to the genus Cycloclasticus have been isolated from a number of geographical locations and display a considerable metabolic versatility as follows ... 

The intensity of the C-T iridium anomaly as a function of geographical location along with the mineralogical and chemical studies of the boundary layers may suggest an impact location when considerably more data are obtained. 

Soil populations and aflatoxin contamination are influenced by weather patterns, with hot dry soils favoring the Aspergillus section Flavi. In terms of geographic location, A. flavus incidence is correlated with high minimum temperatures and inversely correlated to latitude. For example, corn ears that develop at temperatures of 28 to 32°C are far more likely to be contaminated by aflatoxin than ears grown later in the season at lower temperatures. However, late planting is not economically feasible due to lower crop yields. Besides hot dry weather, the level of insect and rodent activity in an area may also substantially favor colonization and aflatoxin production. Plant fertility, density, and disease also play roles in the level of aflatoxin contamination. 

Field evaluation of bromethalin. Both indoor and outdoor field trials against Norway rat and house mouse populations were conducted under an EPA experimental use permit in a number of geographical locations in the U.S.( 15,16) In all cases 0.005% bromethalin was used in a bait containing 65% corn meal, 25% rolled oats, 5% sugar and 5% corn oil(E.P.A. diet). 

It has been estimated that 1.4-7.4 times as many streams in the eastern United States undergo episodic acidification than are chronically acidic (108). Similarly, the number of episodically acidic Adirondack lakes is estimated to be 3 times higher than the number of chronically acidic lakes (108). Wigington et al. (109) reported that acidic episodes occur in a wide range of geographic locations in the northeastern, southeastern, and western United States, as well as in Scandinavia, Europe, and Canada. 

Where to Retire Preliminary Analysis of Geographical Locations... 

The collaboration of professional geochemists which has resulted in this field manual has been widespread both in terms of geographical location and experience. Most of the contributors have been acknowledged as co-authors, but there are many others who have contributed to the preparation of this document. This process has been extremely successful and an active network of European geochemists has developed as a direct result, with a biennially rotating leadership. 

A DISTRIBUTED APPROACH TO THE RECOGNITION OF GEOGRAPHICALLY LOCATED IP DEVICES... 

Large time delays can occur in certain cases because of geographical locations. Suspects should be taken to the nearest sampling location irrespective of divisional boundaries. After sampling they could then be transferred to the appropriate premises if necessary. Although this may generate extra paperwork and inconvenience, obtaining evidence should be the paramount consideration. 

Selected Yield Data for Jerusalem Artichokes and Products Derived Therefrom for a Cross Section of Geographical Locations... 

Greenland, conversely, is characterised by the fact that it is in the northern hemisphere, which contains the largest part of the landmass of the whole Earth (about 67%) and most of the population of our planet. This location, rather close to the industrialised areas of north America, western Europe and northern Russia, does not prevent pollution from easily reaching the ice cap. These opposite peculiarities in terms of geographical location and atmospheric regimes underline why scientists are so interested in conducting parallel research programmes on both ice caps. 

Site coverage the wide variety of geographical locations for the articles suggests an even-handed approach. 

The amathamides (Scheme 10), alkaloids from the Tasmanian marine bryozoan Amathia wilsoni, have been investigated as a function of geographical location of the collected material (152). Populations from the same location did not exhibit qualitative variations in alkaloid content. However, collections from different, geographically proximate locations gave widely varying alkaloid patterns (Table 1.).

The Cenozoic volcanic rocks of the Transantarctic Mountains form the McMurdo Volcanic Group which is subdivided on the basis of geographic location into four provinces (LeMasurier and Thomson 1990) ... 

The initial activity is a known constant through the past 70,000 years independent of passing time and with a value independent of geographical location and the species of dead plant or animal from which the relevant tissues are taken. It is assumed that the sample to be dated was not contaminated by modern radiocarbon and that its observed activity is unaffected by radioactive impurities. Research has shown that the initial carbon-14 activity of modern plant and animal tissues is constant to a first approximation and also that the radiocarbon activity in archeological materials of known age is measurable with sufficient precision to provide radiocarbon dates that agree satisfactorily with the known historical ages.
