In turtles, genetic and morphometric data have often been combined to resolve taxonomic uncertainties (e.g., [18], [19], [20]).
However, open-label placebos have often been combined with positive suggestions such as "we are unsure how placebos work when given honestly, but we have found that they help many people with your condition".
Where there are multiple items they have often been combined into a single measure (Gubernskaya 2010; Liefbroer and Fokkema 2008), a strategy that improves on measurement reliability and facilitates explication but may obscure differences in change across attitudes.
In addition, THAs in hips after pediatric hip diseases have often been combined with predictors of inferior outcome such as young age and inferior uncemented prostheses (Sugano et al. 1998, Furnes et al. 2001).
In recent randomized controlled trials, risk assessment tools and intervention plans have often been combined and studied as part of multifactorial intervention programs which include various modalities, including exercise, medication modification, vitamin D supplementation, environment/assistive technology, and both staff and patient education [ 6- 10].
In previous research, BA has often been studied combined with other waste as substitution materials used for concrete or mortar formulation; e.g., FA+BA (Ginés et al. 2009), contaminated soil+BA (Sorlini et al. 2011), colemanite waste+BA+FA (Kula et al. 2001), FA+scrubber BA+glass frit (Lee et al. 2008), and BA+recycled aggregate (Juric et al. 2006).
The solution to those multi-objective problems has often been searched over the combined strategy space and thus requires the simultaneous optimization of multiple parameters.
To avoid this, perinatal mortality has often been used as measure, combining the stillbirth rate with the early neonatal mortality rate.
Built on a geologically unstable hill of London clay, the castle has often been subject to subsidence; this, combined with the sale of its stonework in the 16th century, has led to it now being ruined.
