San Francisco Estuary and Watershed Science, 2008 Although there is substantial information about the benefits of managed seasonal wetlands to wildlife, little is known about whether this habitat can help support “at risk” native fishes. The Sacramento splittail Pogonichthys macrolepidotus, a California

An Enterprise Control Assessment Case Study of the Energy-Water Nexus for the ISO New England System [PDF]
arXiv, 2019 The electric power generation mix of ISO New England (ISO-NE) is fundamentally changing. Nuclear, coal, and oil generation facilities are retiring while natural gas, solar, and wind generation are being adopted to replace them. Variable renewable energy (VREs) such as solar and wind present multiple operational challenges that require new and ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background Volumetric modulated arc therapy (VMAT) requires an accurate patient‐specific quality assurance (PSQA) program. In clinical practice, this is usually performed using the γ‐index and the two‐dimensional gamma passing rate (2D %GP). A three‐dimensional (3D) index incorporating the patient anatomy could be more useful for the 3D dose ...

Instream ecological flow and reservoir ecological operation in the upper reaches of Irtysh River
MATEC Web of Conferences, 2018 Instream ecological flow (IEF) and flow-related variations were important for healthy river systems. However, water conservancy projects such as reservoirs altered the processes of IEF and thereby posed considerable threat to the health of river systems ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background The dose‐averaged linear energy transfer (LETD) in proton therapy (PT) has in pre‐clinical studies been linked to the relative biological effectiveness (RBE) of protons. Until recently, the most common PT delivery method in prostate cancer has been double‐scattered PT, with LETD only available through dedicated Monte Carlo (MC ...

The Influence of Urban Morphology on Water Scarcity [PDF]
arXivCities play a vital role in providing water to vast populations. Due to an increasing population and the urbanization process, urban water demand is expected to double by 2050. However, some cities are expanding in locations with limited water retention capacity, scarce rainfall and unfavourable shape.
