		Although the resistivity survey was successful and all the archaeological features shown on the topographic survey were detected, the resistance signals were weak and discontinuities between grids presented problems for the interpretation and identification of anomalies which were not related to the visible structures.
		The resistivity survey was initially processed by ‘edge matching’ each of the grids, allowing any discontinuities between grids to be removed, as the sampling strategy of this survey had been changed from a 0.5 m to a 1 m traverse.
		The high resistance signal may reasonably be considered to be due to rubble spread around the small structure in the centre.

	"Short Mtn. (2092')"
		This is an important concept because it is the geology of these areas that is largely responsible for their characteristic terrain.
		Rock type and resistance to erosion - When weighing the various influences on the development of a landscape, bedrock composition is one of the most important factors to consider.
		However, due to (1) resistance of these rocks to erosion, (2) uplift associated with the orogenies of the past, and (3) subsequent isostatic movements, the elevation throughout this area is generally 1000's of feet above sea level.

		The discovery that DDT resistance in Drosophila had a polygenic basis led to the inference that resistance in most insect populations had a polygenic basis.
		In one studied example of resistance of Culex (mosquito) to an organophosphate, gene amplification of an esterase was the mechanism by which resistance was achieved.
		In another studied example of resistance of Drosophila to dieldrin, a single amino acid substitution was discovered in a chloride channel pore, reducing the binding of dieldrin.

		Resistance tomography may be used for imaging shallow aquifers.
		It is possible to determine the depth and extent of saturated rock in a shallow aquifer by resistance tomography.
		The sharp discontinuity between the unsaturated zone and the saturated zone is distinguished by varying resistance to seismic vibrations generated at the surface and recorded by a dot matrix computer display.

	CONTROLS ON HYDRAULIC RESISTANCE IN STEP-POOL CHANNELS (Site not responding. Last check: 2007-10-21)
		The variables that were tested for their effect on flow resistance included discharge, slope (0.10, 0.14 m/m), presence/absence of steps and grains, and LWD density, orientation, piece length, and arrangement.
		Calculations of resistance partitioning indicated that spill resistance and debris resistance were responsible for the largest components of total resistance, and that grain roughness was a small component of total resistance when steps and/or debris were present.
		The relative contributions of grain, spill, and debris resistance depended on discharge, with debris resistance dominating at higher discharges, and debris density, with similar contributions from spill and debris components at low debris densities and greater debris roughness at higher debris densities.

	Rheology in structural geology
		In geology this term is commonly equated to a rock acquiring a distortional strain (rather than simply breaking).
		The effect of reducing the frictional resistance in fault zones is to reduce its ability to support loads (stress).
		While it is possible to measure viscosity of rock materials at the surface under laboratory conditions, in practice it is very difficult to extrapolate short-duration experiments to geological time-scales so as to make good estimates of their long-term viscosity.

	Geology
		The bizarre landforms called badlands are, despite the uninviting name, a masterpiece of water and wind sculpture.
		They are near deserts of a special kind, where rain is infrequent, the bare rocks are poorly consolidated and relatively uniform in their resistance to erosion, and runoff water washes away large amounts of sediment.
		Nature's answer to great resistance is to carve steeper slopes, resulting here in incredibly slender spires above knife-sharp ridges and intricately creased slopes.

	History of geology--Wegener (Site not responding. Last check: 2007-10-21)
		Resistance to the hypothesis of continental drift came from two main sources--geophysicists and American geologists.
		American geology was held in high regard in the early 20th century, and such overwhelming rejection of continental drift put an end to serious scientific discussion of the idea for the next four decades.
		Wegener had good information about continental geology for a few regions, but the geology of many continents was poorly known or not even examined in some cases.

		At the time, drug resistance already posed a substantial threat in those countries, and people felt a tremendous need to call attention to the danger.

		When the channel banks are as erodible as the bed, the reach-scale flow resistance is the dominant component of the system adjustment, resulting in a functional relation between the average water surface slope along the channel thalweg and the ratio of the sediment supply and the imposed discharge.
		Independent estimates of resistance partitioning were developed based on calculations of grain resistance, from Keulegan log-law relations, and of debris resistance, based on calculations of drag force associated with the cylinders used here to represent woody debris.
		Calculations of resistance partitioning indicated that spill resistance and debris resistance were responsible for the largest components of total resistance, and that grain roughness was a small component of total resistance.

	Swaziland National Trust Commission - Malolotja Nature Reserve - Geology, geomorphology, hydrology and soils
		The geology of Malolotja is very diverse and includes some granites (Lochiel Granite, estimated to be about 3 000 million years old), but is predominantly made up of metamorphosed sedimentary rock formations of the Barberton Mountains, including the Onverwacht, Fig Tree and Moodies series of rocks.
		Ironstones and quartzites are common and, because of their greater resistance to erosion, give rise to the rugged relief of the region and stand up as high mountain ranges and peaks.
		The mountainous scenery which is the outstanding feature of the reserve results from a combination of the geology of its rocks and the subsequent landshaping erosion which together have produced the most dramatic and varied scenery in Swaziland.

		In progressive metamorphism of a basalt, the course of change is different because the original basalt reacts differently to heat and pressure.
		In fact, it is so stiff and resistent to the squeezing (unlike wimpy shale) that the first reincarnation as a metamorphic rock is simple recrystallization to a rock called greenstone named because it is made of many green metamorphic minerals.
		Rising temperature and continued squeezing causes new minerals to crystallize, and what was formerly basalt becomes amphibolite, a rock that looks like a dark gneiss and is rich in hornblende and feldspar, but with very little quartz.
