Influence of curing conditions on mechanical properties and microstructure of magnesium potassium phosphate cement

open access: yesCase Studies in Construction Materials, 2022
This study investigated the effects of curing conditions such as dry air curing, moist air curing, water curing, and water-bath curing (30 °C, 50 °C) on hydration performance and mechanical properties of magnesium potassium phosphate cement (MKPC).

Oceanic moisture sources contributing to wintertime Euro-Atlantic blocking [PDF]

open access: yesWeather and Climate Dynamics, 2021
Although conventionally attributed to dry dynamics, increasing evidence points to a key role of moist dynamics in the formation and maintenance of blocking events. The source of moisture crucial for these processes, however, remains elusive.

Moisture origin, transport pathways, and driving processes of intense wintertime moisture transport into the Arctic [PDF]

open access: yesWeather and Climate Dynamics, 2022
A substantial portion of the moisture transport into the Arctic occurs in episodic, high-amplitude events with strong impacts on the Arctic's climate system components such as sea ice.

Numerical Investigation of the Chemical Effect and Inhibition Effect Improvement of C3H2F3Br (2-BTP) Using the Perfectly Stirred Reactor Model

open access: yesEnergies, 2018
The overall chemical rate and chemical effect of CF3Br, 2-BTP and 2-BTP/CO2 with hydrocarbon flames are calculated using the perfectly stirred reactor (PSR) model. The chemical effects of CF3Br with CH4/air flames always inhibit combustion.

CO2 flux estimation errors associated with moist atmospheric processes [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
Vertical transport by moist sub-grid scale processes such as deep convection is a well-known source of uncertainty in CO2 source/sink inversion. However, a dynamical link between vertical transport, satellite based retrievals of column mole fractions of ...

Can climate models capture the structure of extratropical cyclones? [PDF]

open access: yes, 2009
Composites of wind speeds, equivalent potential temperature, mean sea level pressure, vertical velocity, and relative humidity have been produced for the 100 most intense extratropical cyclones in the Northern Hemisphere winter for the 40-yr ECMWF Re ...

Convection of Moist Saturated Air: Analytical Study

open access: yesAtmosphere, 2016
In the present work, the steady-state stationary thermal convection of moist saturated air in a lower atmosphere has been studied theoretically. Thermal convection was considered without accounting for the Coriolis force, and with only the vertical ...
