Lifecycle environmental impacts of electric vehicles are comparatively less well understood and hence studies such as Hawkins et al are needed.
Hence, studies on mechanical strength of PEMFC should focus on that interface.
Hence, studies to predict and improve its behavior continue to be essential.
Hence, studies that avoid such biases are necessary to reveal the mechanisms underlying CM.
Hence, studies involved three factors i.e. Aspects, tillage practices and systems.
Hence, studies concentrated on the design and fabrication of hazard-free lighting sources has been significantly increasing.
Hence, studies on boron nanostructures have become more and more attractive in the recent years[1 13].
Hence, studies of morphology and dynamics of Es, e.g., horizontal shapes and movements, are indispensable to discuss their generation mechanisms.
Hence, studies of tree communities in different forest conservation zones are essential to evaluate the effectiveness of different conservation practices.
Degradation and mortality of corals is increasing worldwide and is expected to have significant effects on coral reef fish; hence studies on these effects are essential.
Hence, studies are performed focusing on real-time traffic which includes video as well as Voice over Internet Protocol (VoIP) transmissions.
