Advantages of application of the backscattered electron scanning image in the determination of soil structure and soil constituents
backscattered electron scanning image soil structure soil components
2008/11/26
Submicroscopic techniques can be broadly subdivided into the study of micromorphology and imaging of the arrangement of the soil particles and voids, and the microchemical analysis of soil components....
Adsorption of water vapour on montmorillonite: grand canonical ensemble monte carlo simulations
water vapour montmorillonite Grand Canonical Ensemble Monte Carlo simulation
2008/11/26
The Grand Canonical Ensemble Monte Carlo simulation method is applied to study adsorption of water vapour on external and internal surfaces of sodium montmorillonite. The model uses MINDO water-clay a...
Acoustic emission as a method for the detection of fractures in the plant tissue caused by the external forces
acoustic emission stress strain plant tissue
2008/11/26
In order to detect fractures in the plant tissue resulting from deformations, the method of acoustic emission has been applied. Simultaneous measurements of the mechanical parameters and the acoustic ...
Accuracy of soil moisture measurement by tdr technique
time domain reflectometry soil moisture measurement error
2008/11/26
The error in the measurement of volumetric water content by the TDR technique results from the correlation imperfections between the directly measured values of soil refractive index, n, and the real ...

2008/11/26
ACCESS-II contains a detailed model of crop growth and soil water use, for use within small areas and with detailed soil and cropping data. The principles behind the detailed model are described. Vali...
A comparison of oxygen diffusion rates in sand moistened with water or peg 20000 solution
ODR PEG solutions water/sand/air mixtures
2008/11/26
Oxygen diffusion rates (ODR) were measured in water/sand/air and PEG solution/sand/air mixtures, spanning a range of liquid/solid/air volume ratios. Replacement of water with PEG solution as the liqu...
A method for estimation of enzymatic browning and its suppression in apple slices
apple slices reflectance browning oxalate sulphite
2008/11/26
A described method is based on diffuse light reflectance in the spectral region 400-720 nm for the examination of enzymatic browning of apple slices. In this method apples are sliced as directly dippe...
About the biophysical mechanisms of the long-distance water translocation in plants
plant s water minera components assimilates transport mechanisms
2008/11/26
The present work discusses the basie mechanisms of water translocation on the so-called long distances. The translocation includes: transfer of water and minera?components across the root (from the so...
Accessibility of most frequently used physical parameters of soil structure, reliability of measured values, lack of replicates andways out of this dilemma
bulk density saturated hydraulic conductivity limited data-sets outflanking techniques
2008/11/26
Assessment of soil structure and still more its changes is impeded by peculiarities of sampling and measurement. Unavoidable local destructions tend to advance use of small numbers of replicates, samp...
