Determination of the melanin and anthocyanin content in barley grains by digital image analysis using machine learning methods.

The pigment composition of plant seed coat affects important properties such as resistance to pathogens, pre-harvest sprouting, and mechanical hardness. The dark color of barley (Hordeum vulgare L.) grain can be attributed to the synthesis and accumulation of two groups of pigments.

Image-based classification of wheat spikes by glume pubescence using convolutional neural networks.

Introduction: Pubescence is an important phenotypic trait observed in both vegetative and generative plant organs. Pubescent plants demonstrate increased resistance to various environmental stresses such as drought, low temperatures, and pests. It serves as a significant morphological marker and aids in selecting stress-resistant cultivars, particularly in wheat.

[The choice of antibiotic according the results of standard bacteriological analysis and express-method without isolation of pure cultures.].

The efficiency of choosing antibiotics using two methods was analyzed. The first method is based on standard laboratory analysis including isolation of pure cultures of prospective agent and detection of their individual sensitivity to antibiotics. The second method is based on a new express-technique permitting to simultaneously evaluate effect of pharmaceuticals on cultivated and not cultivated yet bacteria without isolation of pure cultures.

Effects of Multicide, Antibacterial Drug, on Staphylococcus Biomembranes.

Drug penetration into bacterial biomembranes is one of the most important factors determining the efficiency of antibacterial therapy. Multicide, antibacterial drug, is a nanomolecule 1.3-2.

Characteristics of bacterial biofilms during long-term culturing.

We studied properties of bacterial biofilms during long-term culturing. The biofilms were preserved for more than 90 days under the chosen conditions. At the same time, amounts of matrix and cells underwent periodic changes.
