In the US, agriculture rapidly expanded beginning in the 1850s, influenced by homesteader policies and new technologies.With increased production also came widespread land-use/land-cover change.We analyze historical agricultural policies and associated land and water use trajectories with a focus on the Southern Great Plains (SGPs).Rapid changes in
Hand Wash This study compares the pre- and postprivatization financial and operating performance of 61 companies from 18 countries and 32 industries that experience full or partial privatization through public share offerings during the period 1961 to 1990.Our results document strong performance improvements, achieved surprisingly without sacrifici
There are approximately 200,000 households living in detached houses and gers (yurts) with small coal stoves that burn raw coal in Ulaanbaatar city.A proper heating system and improvement of the energy efficiency of residential dwellings are vitally important for Ulaanbaatar city to reduce air pollution as well as for the operation of the Cable Ent
The new quantum era is expected to have an unprecedented social impact, enabling the research of tomorrow in several pivotal fields.These perspectives require a physical system able to encode, process and store for a sufficiently long amount of time the quantum Cable Entry Wallplate information.However, the optimal engineering of currently availabl
The terminal-connected series dynamic braking resistor (SDBR) is applied to assist the low-voltage ride-through (LVRT) of the doubly-fed induction generator (DFIG).With the fault current and switch-in of the SDBR, the stator voltage oscillates, thus the constant stator voltage drop assumption is invalid and the effect Cleaners of the converter curr
