The only pre-existing studies on the effect of storage on vermicompost [3, 4], have been based on the use of 2-month-old press-mud as feed for earthworms, and assessment of the changes in major nutrients (N, P and K), microbial activity and enzyme activity of the vermicast that was generated.
The main difference of our study population to that of pre-existing studies [ 7- 18, 19] 19] on bronchoscopy under noninvasive ventilatory support is that NIV had already been established in our patients irrespective of a planned bronchoscopy.
This large population-based epidemiological study adds to the existing pre-clinical studies on serum iron and development of specific cancer types.
But many existing studies are methodologically weak; most intervention studies relied on simple pre/post evaluations and only a minority used randomized controlled designs (RCTs) [ 18].
The microstructural and empirical correlations presented in this study can be applied to new wells drilled in geothermal environments and can help refine studies on pre-existing wells, if our correlations hold true at the reservoir scale.
It may not be possible to rely on such pre-existing data in many studies.
To collect cancer-associated proteins, we used a text-mining method and examined experimental applications of 15,663 human proteins to cancer studies based on the pre-existing literature on cancer pathogenesis.
The socioeconomic patterning in hospital admissions is well known from routine data, but this study uses pre-existing morbidity data on a variety of risk factors including blood pressure, smoking and cholesterol, which can assess the degree to which the patterning might be influenced by these risks.
In order to study the influence of pre-existing dislocations on the pop-in phenomenon in magnesium oxide, an original experimental protocol, based on low-rate cleavage, has been developed to introduce a controlled dislocation density in MgO single crystals.
To systematically review studies measuring the influence of pre-existing disability on the risk of sustaining an injury.
Data from this study shows the large impact of pre-existing disease on HRQoL and the importance of accounting for pre-existing disease when the HRQoL of ICU survivors is studied.
