The behavioural phase state and coloration of hatchling Schistocerca gregaria were examined in a series of experiments to determine the means by which phase characteristics are passed between generations. Both crowding of solitary-reared females at the time of oviposition and high egg pod densities promoted behavioural gregarization, although the former appeared to be a rather more potent factor. In contrast, egg pod density alone appeared to promote the development of hatchlings with dark patterns characteristic of the gregarious phase. The phase characteristics of hatchlings were unaffected when sand previously used for oviposition was used to collect further egg pods. Early separation of presumptive gregarious eggs from egg pods laid by crowd-reared females led to solitarization of the hatchlings, indicating that a factor, either in or around the eggs, removed by early separation promoted gregarization. Both the eggs and foam plugs of egg pods from crowd-reared, gregarious females appeared to be a source of this gregarizing factor. In contrast, there was no evidence for a solitarization factor in egg pods from solitary-reared S. gregaria. Saline extracts of egg pod foam plugs produced an active factor which promoted gregarization both in eggs from solitary-reared females and in eggs from gregarious females which were separated and washed to removed the factor. Solitary eggs were influenced by the gregarizing factor in foam plug extracts for up to 1 day after oviposition. Saline extracts of foam plug retained their activity for up to 1 day. Initial studies on the properties of this factor were made. We conclude that the foam plugs of egg pods from crowd-reared, gregarious locusts contain a small (<3 kDa), hydrophilic gregarizing factor which is produced at the time of oviposition and which predisposes hatchlings to attain characteristics of the gregarious phase.

In order to assess the risks and determine the optimal actions to ensure the safety of work at chemical and petrochemical plants, a method has been developed that allows identifying operations that require optimization and the introduction of additional protective measures. A brief overview of the key factors that affect the safety and effectiveness of operations is provided. The method is based on the concept of zero injuries — Vision Zero, which assumes that absolutely all accidents at work can be prevented. This method is necessary for a deeper analysis of production operations and improving the level of safety protection.

The article is devoted to the analysis of scientific approaches to the interpretation of the concepts of "state regulation", "state regulation of banking", "banking regulation" and the measures on which the state regulation of banking is based. An analysis of the scientific literature in various fields allows us to conclude that scholars ambiguously interpret the term "state regulation of banking." Most often, state regulation of banking is seen as a system of measures by which the state through authorized bodies regulates the activities of banks. The domestic legislator considers the concept of "banking regulation" as one of the functions of the National Bank of Ukraine, which is to create a system of norms governing the activities of banks, determine the general principles of banking, banking supervision, liability for violations of banking legislation. The main purpose of banking regulation is security and financial stability of the banking system, protection of the interests of depositors and creditors. The importance of state regulation of banking as an integral part of public policy is emphasized. Effective state regulation of banking activities should ensure stable and uninterrupted operation of the banking system, guarantee the provision of quality services by banks to depositors and borrowers and protect their interests. Preventive and protective measures on which the state regulation of banking activity in Ukraine is based are considered. Preventive measures should be implemented through the approval of mandatory regulations. The application of protective measures should provide protection against the already threatening situation for the bank. Attention is also paid to the forms in which state regulation of banks by the National Bank is carried out. Such forms are administrative regulation and indicative regulation.

<div>Acid-driven multiphase chemistry of isoprene epoxydiols (IEPOX), a key isoprene oxidation product, with inorganic sulfate aerosol yields substantial amounts of secondary organic aerosol (SOA) through the formation of organosulfur. The extent and implications of inorganic-to-organic sulfate conversion, however, are unknown. Herein, we reveal that extensive consumption of inorganic sulfate occurs, which increases with the IEPOX-to-inorganic sulfate ratio (IEPOX:Sulf<sub>inorg</sub>), as determined by laboratory and field measurements. We further demonstrate that organosulfur greatly modifies critical aerosol properties, such as acidity, morphology, viscosity, and phase state. These new mechanistic insights reveal that changes in SO<sub>2</sub> emissions, especially in isoprene-dominated environments, will significantly alter biogenic SOA physicochemical properties. Consequently, IEPOX:Sulf<sub>inorg</sub> will play a central role in understanding historical climate and determining future impacts of biogenic SOA on global climate and air quality.</div>

As a result of the studies carried out, a complex of diseases on soybeans was identified: ascochitis, peronoscrosis and root rot. The studies carried out indicate a wide spread of diseases in the studied culture and the need to develop a set of protective measures to combat them. The greatest biological effectiveness was selected in the variant when using a complex of fungicides Redigo Pro + Prozaro, which averaged 93.7% for diseases.
