The Impact of Calcium Depletion on Proliferation of Strain DSCG150.

This study analyzed the effects of Ca metal ions among culture medium components on the strain DSCG150 strain cell growth. The strain DSCG150 grew based on a multiple fission cell cycle and growth became stagnant in the absence of metal ions in the medium, particularly Ca. Flow cytometry and confocal microscopic image analysis results showed that in the absence of Ca, cell growth became stagnant as the cells accumulated into four autospores and could not transform into daughter cells.

Detection of cracks on tomatoes using a hyperspectral near-infrared reflectance imaging system.

The objective of this study was to evaluate the use of hyperspectral near-infrared (NIR) reflectance imaging techniques for detecting cuticle cracks on tomatoes. A hyperspectral NIR reflectance imaging system that analyzed the spectral region of 1000-1700 nm was used to obtain hyperspectral reflectance images of 224 tomatoes: 112 with and 112 without cracks along the stem-scar region. The hyperspectral images were subjected to partial least square discriminant analysis (PLS-DA) to classify and detect cracks on the tomatoes.
