Energy consumption-time curvesWe present a new derivation of a key formula for the rate of change of energy consumption with respect to journey time on an optimal train journey. We use a standard mathematical model (Albrecht etal., 2015b; Howlett, 2000; Howlett etal., 2009; Khmelnitsky, ...
Furthermore, for an (NVT) ensemble we have(6)S/kB=lnQ+U/Twhere U is the system's internal energy, which allows us to replace Qa/Qg = eSa/kB under the condition that the process is isothermal and the total energy of the system does not change during a particle jump, which is ...
Energy expenditure correlated with the rate of change in body weight over a two-year follow-up period (r = -0.39, P less than 0.001). The estimated risk of gaining more than 7.5 kg in body weight was increased fourfold in persons with a low adjusted 24-hour energy expenditure (200 kcal...
During power reduction transitions of a fuel cell power plant, the excess electric energy generated by consumption of reactants is extracted, during one or more periods of time, by a voltage limiting device control (200) in response to a controller (185) as i) energy dissipated in a resisti...

The inflation rate for housing and energy in the European Union peaked at 23.3 percent in October of 2022, after which it declined rapidly, passing into deflation (a decline in the absolute price level) by September 2023. In December 2023, the rate of inflation was -1.3 percent. During that...
The rate coefficients of ion charge exchange reactions between atomic oxygen ions and molecules of oxygen and nitrogen have been measured at thermal energies by the afterglow method. This method, described by Dickinson and Sayers, (1) consists of measuring the rate of change of a particular ion ...
