The variations of the surface acidity of the solids, followed by IR of adsorbed pyridine and hammett indicators, indicated a population of Brönsted type sites above 800 μ mol/g, while the surface area increased from 23 up to 105 m2/g.
Two other indicators indicated a similar trend over two years before being withdrawn (registration of fragility fracture and over-75 s with a fragility fracture assessed and treated for osteoporosis risk).
The survey also gave low marks to the V6 Camry's automatic transmission, the V8 Tundra's four-wheel-drive system and the power accessories on the all-wheel-drive Lexus GS. "None of our internal indicators indicated any problems with the three models that didn't get recommended," Mr. McCandless said.
We stress the need of an explicit incorporation of the interactions between climate change and land use dynamics to understand what are current climate change indicators indicating and be able to isolate real climate change impacts.
Therefore, for each participant at each visit, there are fourteen binary indicators indicating the presence or absence of the fourteen HR-HPV genotypes, respectively.
Three models were evaluated: univariate logistic regression using indicators representing alcohol use (Model 1), multivariate logistic regression using indicators indicating alcohol use (Model 2) and multivariate logistic regression using drinking patterns (Model 3).
We used medical records as gold standard when assessing validity of the Obstetric Database and found that sensitivity, specificity, and predictive values generally were high for the selected eleven indicators indicating high validity of the database.
These ice-wedge casts are important as paleoclimatic indicators and indicate a climate of the past with at least a mean annual air temperature of −6 or −8 °C or colder.
Whereas the various geochemical indicators consistently indicate a contrast in redox conditions between I4 and I5, unraveling the underlying hydrogeological factors at this small scale would require further study.
