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...

2008/11/24
The authors developed a sorting line for sizing and sorting of apples. Different size apples were taken from storage and were sorted to improve fruit quality. Apples from the outlets of sorter were ca...
Some physical parameters in relation to water extraction by roots of two pigeonpea genotypes
physical parameters pigeonpea
2008/11/24
In modeling water extraction by roots and in whole crop modeling, careful selection of the factors for their parameterization which could differ from genotype to genotype is a prerequisite. Some physi...

The present study reviews results of research on the quantitative determination of cell structural parameters such as: surface area, perimeter, Ferret's diameters, elongation, compac- tion, for the pa...
Effect of hydraulic press parameters on crude palm oil yield
palm oil processing oil yield parameters design optimisation
2008/11/21
An investigation was carried out on the effect of hydraulic press parameters such as press cage diameter (D) (80, 120, and 150 mm) and wall pore diameter (H) (4, 6, and 10 mm) and expression pressure ...
Effect of stress on stereological parameters of polished sections of soil samples*
stereology image analysis histogram grain size distribution soil aggregate
2008/11/20
Subjecting soil to uniaxial stress causes its compaction and, at the same time, a change in its structure. So, it is important to find methods allowing to estimate such changes. The present study prop...
