Abstract

The article features a systemic approach to digitalization in mining, covering the production process, supervision and management. Business continuity management of a critical infrastructure was characterized with respect to an industrial facility, i.e. a mine. The “SILESIA” Integrated Security System was described. This solution, offered by CNP EMAG, is an example of a systemic approach successfully implemented in industry. The article includes information about the development of technological hardware solutions as well as software which is able to assess the solutions developed in the SecLab Information Security Technology Development Laboratory in the EMAG Institute.

Abstract

A novel herbicidal controlled release formulation composed of (2,4-dichlorophenoxy) acetic acid (2,4-D) chemically bonded to biodegradable (R,S)-3-hydroxybutyric acid oligomers was investigated. The synthesis of (R,S)-3-hydroxy butyric acid oligomers was carried out via the ring opening polymerization of β-butyrolactone initiated by 2,4-dichlorophenoxy acetic potassium salt in the presence of complexing agents. The formed oligomers were characterized by size exclusion chromatography, proton magnetic resonance and electrospray mass spectrometry in order to fi nd out their molar mass distribution and molecular structures. An assessment of biological effectiveness of the obtained herbicidal formulation was carried out in the greenhouse vs. Sinapis alba var. Nakielska. A promotion of the controlled release formulation with decreased water solubility and with low vapor pressure of the active ingredient, instead of traditional formulations of 2,4-dichlorophenoxy acetic acid may help to ensure a greater safety for workers and reduce the risk of dissemination of the active ingredient in the soil profi le.
