Background: The COVID-19 pandemic presented families with novel challenges.Mothers were at particular risk for parental burnout, however, there is limited research on self-care behaviors to ameliorate it explicitly for mothers of young children (aged 3 and younger).Moreover, there has been little in-depth analysis on barriers to self-care and how m
Power supply systems of spacecrafts based on controlled converters with intermediate high frequency link
The authors have considered the methods of summing the energy of solar cell and rechargeable battery by invert-transformer converters with intermediate high frequency link which allow matching sufficiently different the levels of source voltages with load.It was shown that the structure with addition of inverter output voltages in general loop allo
Mechanical properties of discarded shield residue improved by calcium carbide slag and fly ash as subgrade filling.
To utilize discarded shield residue and alleviate the shortage of subgrade filling, industrial wastes such as calcium carbide slag (CCS) and fly ash (FA) were considered to enhance the mechanical properties of the shield residue.A series of laboratory tests, including California Bearing Ratio (CBR) tests, unconfined compressive strength (UCS) tests
Hydrodynamic Loads and Overtopping Processes of a Coastal Seawall under the Coupled Impact of Extreme Waves and Wind
Driven by strong winds, huge ocean waves can cause devastating destruction to coastal HERBAMARE SODIUM FREE regions during harsh weather events.There is growing evidence showing that extreme waves can occur in both shallow and deep waters.To protect the coast against the destructive power of huge waves, coastal protection facilities, such as seawal
