Despite the benefits for communal property, the situation with introduction of energy saving technologies in higher educational institutions of state ownership, directly subordinated to the Ministry of Education and Science of Ukraine or other profile ministries, remains unclear.
Main reasons are the use of outdated materials and technologies for the construction of buildings.

In this sense, one of the most important points in geochemical prospecting is the selection of threshold values to separate the regional background (understood as the mean content of each element considered in a geological material) and the positive geochemical anomalies, i.e. unusually high contents of those elements in that particular geological context.

This value has been confirmed through experimental calibration using a range of material types, stress histories and stress levels [5,6].
During the consolidating procedure of soil deposits, the nozzle can be replaced with sample profile or trimming tools if a specific surface or material removal is required.

Combining the numerical simulations and calibration on realistic materials, the plastic work can be estimated and the irreversible work can be easily calculated from the load-displacement curve.
The interfacial toughness can be estimated by treating the interface as a homogeneous material with the Young's modulus and hardness as composite parameters of the coating and substrate so that linear fracture mechanics for brittle materials can be applied.
Marshall et al [43] proposed a model to relate the toughness of brittle bulk materials to the depth where lateral cracks occur and the crack driving force Pr due to the residual stress during unloading.
