A Review Of The Effects Of Dietary Restriction, Dehydration, And Caffeine Withdrawal On Cognition: Implications For A Disabled Submarine Scenario, Sarah Chabal
Journal of Human Performance in Extreme Environments
In the event that submariners become trapped aboard a disabled submarine (DISSUB), they must perform a multitude of cognitively demanding tasks in order to maximize their likelihood of survival. During this time, submariners will also be forced to endure poor living conditions, including drastic changes to their nutrition. These nutritional changes have the potential to impair submariners’ cognitive functioning and affect operational performance, which could jeopardize survival; however, the effects of DISSUB nutrition on cognitive performance are not well understood. This review first describes the unique nutritional conditions that submariners will experience in a DISSUB scenario, including the change to …

Impact Of Excessive Pumping On Groundwater Quality: The Arsenic Problem Of The Ganges–Meghna–Brahmaputra Delta In Southeast Asia, Rhitwik Chatterjee, Mousumi Chowdhury
Journal of Environmental Science and Sustainable Development
This review of the impact of large-scale pumping on arsenic distribution reveals that groundwater-fed irrigation and domestic withdrawal impart tremendous stress on the limited groundwater resource base and disrupts the dynamic equilibrium of the groundwater system of the Ganges–Meghna–Brahmaputra (GMB) delta in Southeast Asia. Excessive groundwater extraction through pumping affects the groundwater quality in three major ways. First, excessive pumping transports atmospheric oxygen and organic-rich surface water to the subsurface. Second, it promotes arsenic build up in surface soil irrigated with arsenic-laced groundwater. Finally, it shifts groundwater replenishment zones lying at various depths near extraction points, thus, carrying dissolved arsenic …

What Can We Learn About Research Narratives From Professional Storytellers?, Kim Wilkins, Helen Marshall
What Can We Learn About Research Narratives From Professional Storytellers?, Kim Wilkins, Helen Marshall
The STEAM Journal
This short note on practice reflects on how “research narrative” is a much-used, but misunderstood term. Compelling stories about our research are important: for public-facing communications and for academic tenure confirmation and promotion. They are also important for researchers to gain a clearer sense of their own vision and values in the research process: they are not just a communication skill, they’re a career skill. But often researchers in STEM disciplines do not have the practical skills to write stories. We draw on our own practice as creative writers to share some simple and effective methods to bring arts expertise …
