Simultaneous Analysis of Nitrates and Major Organic Acids in Spinach Using Capillary Electrophoresis
Organic Acids Nitrates Capillary Electrophoresis
2009/7/10
It is necessary to decrease the concentrations of nitrate and oxalate in spinach for human health. This analytical method was developed to simultaneously determine nitrate, oxalate and other major org...
Effect of Nutrient Composition Used in the Closed Hydroponics System with Capillary Uptake Method on Nutrient Element Concentrations in the Organic Substrates and Yield of Tomato
electric conductivity organic substrates ratio of nutrient absorption per water consumption
2009/7/9
A modified nutrient solution formula was evaluated for tomato production in a new closed hydroponics system aimed to reduce emission. The new system is a closed organic substrates (cryptomeria bark) c...
Scaling of two-phase capillary pressure-saturation relationships: water-air and oil-air systems
immiscible phases capillary pressure-satura- tion relationship interfacial tension scaling
2008/12/2
Solutions of various problems related to soil contamination by nonaqueous phase liquids (NAPL) require a knowledge of capillary pressure-saturation relationships. In soil-water-air systems, this rela...
Effect of peat decomposition on the capillary rise in peat-moorsh soils
capillary rise peat moorsh unsaturated hy- draulic conductivity
2008/11/20
The paper shows the application of the steady state soil moisture flow theory for three different peat-moorsh (Ferric Histosols) soil profiles from the Biebrza River Valley. The unsaturated hydraulic ...
