What We Know About Stemflow's Infiltration Area

Frontiers in Forests and Global Change, 2020
A portion of precipitation drains to the surface down plant stems, as “stemflow.” Although per observations to date, stemflow rarely represents >2% of gross precipitation in forests, it can result in larger water fluxes to near-stem soils that are ...

Partitioning of Ca to Metastable Precipitates in a Mg-Rare Earth Alloy

SSRN Electronic Journal, 2022
The potential effect of the element Ca on the precipitation behavior was investigated in an Mg-rare earth alloy. A combination of metastable β′′′ and β′ precipitates was observed for the peak aging condition at 200°C. Ca addition was found to have no significant effect on the precipitating phases and evolution sequence. Composition analysis showed that

Partitioning of microbial cells between clouds and precipitation [PDF]

, 2020
<p>It is known that microorganisms are present in the outdoor atmosphere, in clouds and precipitation. These microorganisms originate from various local and distant sources and consist of very diverse and ephemeral communities. The most abundant bacterial taxa typically include Alpha-, Beta- and Gamma-Proteobacteria, with notably

Large impact of extreme precipitation on projected blue–green water partitioning [PDF]

Earth System Dynamics
Precipitation partitioning into blue (runoff) and green water (transpiration) flows is a fundamental hydroecological process shaping freshwater availability across vegetated and hydrologically active land areas.

Localized Augmentation of Net Precipitation to Shrubs: A Case Study of Stemflow Funneling to Hummocks in a Salinity-Intruded Swamp

Frontiers in Forests and Global Change, 2021
The interception of precipitation by plant canopies can alter the amount and spatial distribution of water inputs to ecosystems. We asked whether canopy interception could locally augment water inputs to shrubs by their crowns funneling (freshwater ...

Decomposition characteristic of austenite retained in GCr15 bearing steel modified by addition of 1.3 wt.% silicon during tempering

Journal of Materials Research and Technology, 2019
The decomposition characteristic of austenite retained in a GCr15 bearing steel modified by the addition of 1.3 wt.% silicon during tempering was investigated by microstructural observation, X-ray determination, and dilatometric experiment.

Precipitation Versus Partitioning Kinetics during the Quenching of Low-Carbon Martensitic Steels [PDF]

Metals, 2020
Low-carbon, low-alloy steels undergo auto-tempering and carbon partitioning to austenite during quenching to martensite. The microstructures of two such steels quenched at two cooling rates have been evaluated using electron microscopy to characterise lath and carbide precipitate morphologies, and the results have been compared with theoretical ...

Precipitation and evapotranspiration partitioning on the Three-River Source Region: A comparison between water balance and energy balance models

Journal of Hydrology: Regional Studies, 2021
Study Region: Three-River Source Region, Qinghai-Tibetan Plateau, China. Study Focus: Evapotranspiration (ET) is often the largest loss of water from grassland ecosystems and consists of two constituents: evaporation (E) and transpiration (T), but it is ...

Tropical Continents Rainier Than Expected From Geometrical Constraints

AGU Advances, 2022
Abundant rainfall over tropical land masses sustains rich ecosystems, a crucial source of biodiversity and sink of carbon. Here, we use two characteristics of the observed tropical precipitation distribution, its distinctive zonal arrangement and its ...
