An undiscovered facet of hydraulic redistribution driven by evaporation—a study from a Populus tomentosa plantation
Populus shallow root system drought stress lateral roots (LRs) Populus tomentosa EDHR
2023/12/6
Maintaining the activity and function of the shallow root system of plants is essential for withstanding drought stress, but the associated mechanism is poorly understood. By investigating sap flow in...
Grooving of a grain boundary by evaporation–condensation below the roughening transition
grain boundary evaporation–condensation below roughening transition
2015/10/16
The development of surface grooves at grain boundaries that intersect a planar surface is analyzed for the case that the evolution occurs below the thermodynamic roughening transition by evaporation–c...
DISCRETE AND CONTINUUM RELAXATION DYNAMICS OF FACETED CRYSTAL SURFACE IN EVAPORATION MODELS
crystal surface evaporation facet Burton–Cabrera–Frank model subgradient formalism free-boundary problem shock
2015/10/16
We study linkages of two scales in the relaxation of an axisymmetric crystal with a facet in evaporation-condensation kinetics. The macroscale evolution is driven by the motion of concentric circular,...

Stable isotope estimates of evaporation : inflow and water residence time for lakes across the United States as a tool for national lake water quality assessments
inflow water residence
2014/11/28
We used water d2H and d18O from ca. 1000 lakes sampled in the 2007 U.S. Environmental Protection Agency’s
National Lakes Assessment (NLA) to assess two hydrological variables—evaporation as a percent...
A regime shift in Lake Superior ice cover, evaporation, and water temperature following the warm El Nin˜ o winter of 1997–1998
ice cover evaporation water temperature
2014/11/28
Significant trends in Lake Superior water temperature and ice cover have been observed in recent decades, and
these trends have typically been analyzed using standard linear regression techniques. Al...
Thermodynamic Limits of Work and Pressure Gain in Combustion and Evaporation Processes
Work and Pressure Gain Combustion Evaporation Processes
2014/11/13
Combustion and evaporation processes occurring in a closed chamber can result in significant pressure rise and direct work transfer. The pressure and volumetric changes that accompany such processes a...

Geostatistical Analysis of Rainfall Temperature and Evaporation Data of Owerri for Ten Years
Evapotranspiration Rainfall Temperature Oscillations
2013/2/26
Rainfall, evaporation and temperature data of Owerri for ten years (Figure 1) (1998-2007) were acquired. The data were analyzed using standard statistical measures and climatological normal (Figure 2)...

Our project concentrates on manufacture of light panels based on available natural materials (expanded perlite, sawdust and refuse of wood, vegetable coal.) mixed with a natural resin not toxic (resin...
New Constraints from Pb-Evaporation Zircon Ages of the Méiganga Amphibole-Biotite Gneiss, Central Cameroon, on Proterozoic Crustal Evolution
Metasediment 207Pb/206Pb Ages Crustal Evolution
2013/3/6
The amphibole biotite gneiss (ABGn) in the Méiganga area forms part of a meta volcano-sedimentary sequence of the Adamawa Yade domain (AYD), Central African Fold Belt (CAFB). This sequence shows affin...
Global land-surface evaporation estimated from satellite-based observations
Global land-surface satellite-based observations evaporation estimated
2011/3/14
This paper outlines a new strategy to derive evaporation from satellite observations. The approach uses a variety of satellite-sensor products to estimate daily evaporation at a global scale and 0.25 ...
We present a detailed analysis of results from a new study of the quantum evaporation of Callan-Giddings-Harvey-Strominger (CGHS) black holes within the mean field approximation. This semi-classical t...
覆膜开孔蒸发条件下土体高度对水盐运移的影响（Effects of Soil Column Heights on Movement of Soil Water and Soil Salt-during Evaporation under Perforated Plastic Mulch）
覆膜开孔率 土体高度 单位深度累积蒸发量
2010/12/29
通过不同高度土体在不同覆膜开孔率条件下的室内蒸发试验，研究了土体高度变化时水盐分布的差异与相互联系。试验结果表明，不同高度土体的单位深度累积蒸发量与时间变化符合Gardner理论关系，单位深度累积蒸发量与时间和土体总高度存在二元线性函数关系；单位深度累积蒸发量和单位膜孔面积单位深度累积蒸发量均与土体高度和覆膜开孔率存在较好的函数关系；土体高度越小，单位深度含盐量和盐分浓度变化幅度越大，土体高度是影...
