In Chile, the school's graduates ran Pinochet's secret police and three principal concentration camps.
Continental margins provide the Earth's principal concentration of hydrocarbon and mineral resources, earthquakes, landslides, and volcanic and climatic hazards.
The principal concentration of research is, of course, to be found in the regions with the longest history in semiconductor research that is, North America, Europe, and Japan.
Regarding the principal macroelements concentrations from Turulung soil genetic type, it can be observed (Table 1) that the highest Na and Ca concentration were found in 20 40 cm horizon (6737.44 mg/kg respective 6699.34 mg/kg).
The highest principal stress concentration was seen at the buccal concavity of the maxillary implant; this may play a role in osseointegration with highly angled implants in the posterior maxilla.
The reaction kinetics were studied by producing more than 300 solution samples during which the principal heavy metal concentrations, pH and Eh were measured.
Despite much speculation, the principal factors controlling concentrations of polycyclic aromatic hydrocarbons (PAH) in settled house dust (SHD) have not yet been identified.
The principal controls on concentrations of DO in the Kirkwood-Cohansey aquifer and other unconfined aquifers are the volume of recharge reaching the water table, concentrations of DOC and DO in aquifer recharge, and the amount and bioavailability of POC in the aquifer.
At surgical concentrations their principal effects are on ligand-gated (rather than voltage-gated) ion channels, with potentiation of postsynaptic inhibitory channel activity best fitting the pharmacological profile observed in general anaesthesia.
Concentrations of principal stress and plastic strain occur beneath the pipeline bend and both the principal compressive stress and resulting plastic strain become very small away from the pingo.
