Geometrical characteristics of eggs from 3 poultry species

open access: yesPoultry Science, 2021
We studied the correlations between egg geometrical parameters (i.e., egg shape index, sphericity, geometric mean diameter, surface area, and volume) and eggshell qualities, or the organic matrix in eggshell.

Comparison between three static mixers for emulsification in turbulent flow [PDF]

open access: yes, 2011
This paper deals with comparing performances of three different static mixers in terms of pressure drop generated by both single-phase flow and liquid–liquid flow in turbulent flow regime and in terms of emulsification performances.

Unravelling intermittent features in single particle trajectories by a local convex hull method [PDF]

open access: yes, 2017
We propose a new model-free method to detect change points between distinct phases in a single random trajectory of an intermittent stochastic process. The local convex hull (LCH) is constructed for each trajectory point, while its geometric properties ...

Load estimation from photoelastic fringe patterns under combined normal and shear forces [PDF]

open access: yes, 2009
Recently there has been some spurt of interests to use photoelastic materials for sensing applications. This has been successfully applied for designing a number of signal-based sensors, however, there have been limited efforts to design image-based ...

Crop Residue Return Rather Than Organic Manure Increases Soil Aggregate Stability under Corn–Soybean Rotation in Surface Mollisols

open access: yesAgriculture, 2022
Fertilization practices change soil organic carbon content and distribution, which is relevant to crop rotation and soil aggregates. However, how fertilization management under corn–soybean rotation affects soil organic carbon and aggregate stability at ...
