A major drawback underlying the relatively low light harvesting ability and the concomitant reduced photocurrents in quantum dot sensitized solar cell devices is the amount of QDs adsorbed on the TiO2 electrode.
In this study we review not only the various approaches used for such conversion but we also carefully look at the advantages, the drawbacks and underlying assumption of each approach.
Barriers have to be identified and may relate to guidelines themselves (when unclear or too difficult to implement) but also to physicians (inertia,lack of awareness, familiarity, agreement, self-efficacy, outcome expectancy, ease of prescription, anticipated drawbacks), patients (underlying the importance of taking their preferences into account) or healthcare systems ("external barriers").
Although Hadoop can support large-scale parallel data processing, there are still drawbacks to its underlying architecture and processing model in product environments, which caused the bottleneck in processing efficiency and performance.
In addition, however, wireless mesh networks add the drawbacks of the underlying wireless medium.
Some of these methods are termed to be effective; also they possess underlying drawbacks such as high cost, intensive energy requirements, and formation of hazardous byproducts and generation of sludge which causes secondary pollution [ 3].
One drawback of AM is that the underlying population stratification due to breeding history, selection, genetic drift, or founder effects can lead to false associations [ 26, 27].
The principal drawback is that no inference to the underlying target population is possible.
The TNM-based staging systems have an important drawback: these systems do not account for underlying liver disease [ 40].
