Many elements emit gamma rays at multiple, often widely spaced energies, so gamma-ray measurements can in principle also be used to identify depth-dependent variations in subsurface composition.
To identify depth-specific changes in proteoglycan due to loading, the outcome measures were mean integrated value of proteoglycan in the superficial zone of cartilage, mean integrated value of proteoglycan in the mid zone of cartilage, and mean integrated value of proteoglycan in the deep zone of cartilage.
Cox regression multivariate analysis identified depth of tumour invasion (P=0.0091), lymph node metastasis (P=0.0003), and positive surgical margin (P=0.0375), as independent unfavorable factors.
Univariate analysis performed by Cox regression identified depth of tumour invasion (P<0.0001), distant metastasis (P=0.0002), lymph node metastasis (P<0.0001), lymphatic invasion (P=0.0021), positive surgical margin (P<0.0001), and High HIF-1 α expression (P=0.0011) as correlating with survival (Table 4>).
By comparing Fig. 5 with the previously identified depths of the water and hydrocarbon-bearing horizons (Figs. 3, 4), good matching can be observed between both.
By this strategy, minimum and maximum horizontal stress profiles are determined in such a way that the stress concentration at the wellbore wall at the tensile fracture identified depths, exceeds the formation tensile strength, while at the breakouts identified depths it exceeds the compressive strength of the formation.
"It effectively says we can identify the depth of racial inequality without doing anything about it," she said.
Sulfate and methane profiles from core porewaters were analyzed to identify the depth where sulfate and methane approached minimum concentrations.
Although we lack the data necessary to identify the depth of a faunal break between rariphotic reef fishes and deep-sea fishes at Curaçao, the lower limit of the rariphotic may lie below 309 m.
The acceleration record of the beam tip was sufficient to detect the existence of the crack and to identify crack depth and site.
The parameters of a typical deep mine winder are used to identify the depth locations of the resonance regions during the ascending cycles with various winding velocities.
