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...
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...
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,...
Simulating condensational growth, evaporation, and coagulation of aerosols using a combined moving and stationary size grid.
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...
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...
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...
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. Alt...
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...
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...
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...
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...
设计了一种基于蒸发量的简易灌溉预警装置,并建立了基于水量平衡原理的灌溉预警模型。通过田间试验,确定了适宜供水条件下新疆膜下滴灌棉花各生育阶段的蒸发皿—作物系数,并建立了适宜的灌溉预警指标,提出了降雨条件下的指标修正方法。田间应用表明,在北疆棉花膜下滴灌条件下,苗期、蕾期、花铃期和吐絮期分别以累计蒸发量达到140、75、50和120mm来控制灌水时间,以0.15、0.4、0.7和0.25倍的累计蒸...
