The term environmental flows has become widely used to define the hydrological regime required to sustain freshwater and estuarine ecosystems and the human livelihoods and well-being that depend on them. A large range of frameworks and methods has been developed to assess environmental flow needs and many authors have identified subtleties in the approaches needed for different situations and r...

background: sellick's maneuver (cricoid pressure) may make laryngoscopic view and tracheal intubation more difficult. this study compared the different techniques of cricoid pressure (cp) regarding to the laryngoscopic view and time to intubation. methods: in142 anesthetized patients, 4 types of cp was randomly applied; a) one-handed cp using thumb, index and middle fingers, b) one-handed cp us...

Abstract We use fluctuating magnetic helicity to investigate the polarization properties of Alfvénic fluctuations at ion-kinetic scales in solar wind as a function β p , ratio proton thermal pressure pressure, and θ vB angle between flow local mean field, B 0 . Using almost 15 yr Wind observations, we separate contributions from with wavevectors, k quasi-parallel oblique finding that is consist...
