Electrical Penetration Graph (EPG) is a well-established technique for studying the feeding behavior of stylet-bearing insects. Here we show a new application of EPG as a non-invasive tool for the acquisition of intracellular electrophysiology recordings of sieve elements (SEs), the cells that form the phloem vasculature in plants.

Sieve Analysis and Grading Curves

Sieve analysis is a method used to determine the particle size distribution of aggregate materials. This process involves the following steps: The required quantity of dried sample of aggregate is weighed. The weighed aggregates are sieved through a set of sieves with square openings arranged in descending order of aperture size, with the largest mesh on top (Column 1 of Table 1). The stack of sieves is shaken or vibrated to facilitate the sorting of particles by size. After sieving for a...

The main focus of this protocol is to efficiently isolate viable primary glomeruli cultures with minimal contaminants for use in a variety of downstream applications. The isolated glomeruli retain structural relationships between component cell types and can be cultured ex vivo for a short time.
FAQs
The descending mesh sequence separates a sample into ordered size fractions rather than producing only a coarse and fine split. Larger particles remain on upper sieves, while smaller particles continue downward until an opening excludes them. This arrangement preserves size information across the sample and supports detailed assessment of grading, uniformity, and material behavior.
Mechanical agitation repeatedly moves particles across the sieve surfaces, increasing their opportunities to encounter and pass through suitable openings. Controlled shaking helps maintain a consistent separation process, while the retained material on each sieve represents particles that could not pass that mesh. The resulting fractions provide a basis for comparing particle sizes within the sample.
Weighing the material retained on each sieve shows how the sample is distributed among different particle-size ranges. The combined fraction data reveal whether the material is relatively uniform or broadly graded, information that can support evaluation of handling and compaction behavior. In engineering analysis, these results also help guide material selection and process decisions.
Particle-size distribution results help engineers evaluate material uniformity and anticipate how granular materials may behave during handling and compaction. A distribution spread across several sieve fractions indicates the relative presence of different size classes, while the measured fractions provide evidence for comparing materials. These comparisons can inform processing conditions and engineering design choices.
A typical analysis places the granular sample in a stack of sieves arranged from larger to smaller mesh openings, then applies controlled mechanical shaking. After separation, the material retained on each sieve is collected or assessed by mass. The fraction weights are then used to characterize the sample’s particle-size distribution and evaluate its suitability for the intended use.
Engineers use sieve shaking for aggregate grading, soil characterization, and powder quality control when particle-size information is needed. The method supports research as well as manufacturing and construction decisions, including assessment of material uniformity and selection of processing conditions. Its results can also contribute to process design by linking size distribution with expected handling or compaction behavior.
