Finite Element Analysis of Self-Healing Concrete Beams Using Bacteria.

Deterioration or crack formation in concrete elements is a phenomenon that cannot be easily avoided, and it has a high cost of repair. A modern technology that needs wider study is the use of the bio-precipitation of calcium carbonate using bacteria to increase a structures' capacity. The current research presents an analytical study on self-healing concrete beams using bacteria to enhance the beam's capacity.

Treated livestock wastewater influence on soil quality and possibilities of crop irrigation.

This work aims to investigate how livestock wastewater irrigation affects the quality and agricultural potential of soil. The experiments took place in 2019 on a research station with an area of 10 ha (Moscow region, Russian Federation), divided into two even sites of 5 ha (control, experimental). Eleven germination experiments were carried out to determine the influence of livestock wastewater irrigation on radish seeds (1 - control; 10 - irrigation with liquid and solid phases of wastewater samples mixed with pure water).
