The research paper demonstrates a comprehensive comparative analysis of the state of coniferous plantations in Minsk in areas with a favourable and predominantly unfavourable ecological situation and control trees growing in relatively clean territories. The morphological-anatomical and bilateral (in terms of fluctuating asymmetry) patterns of needles of Scots pine (Pinus sylvestris L.) change were revealed, reflecting the severity of anthropogenic press on the urban environment. The possibility of using the FTIR spectroscopy method combined with chemometric analysis algorithms for the differentiation of needles is shown. Using the method of principal components, the test samples were divided into clusters reflecting the extent of their anthropogenic load.

Scots Pine Needles

Phenolic compounds distribution was studied along the length of Scots pine needles from trees in a polluted and a control site. There is no significant difference in the content of total phenols between the studied sites. There are significant differences in distribution of phenolics along the length of needles. The highest content is in the tip part of the needle and the lowest at the base. This kind of distribution suggests a role of these compounds in the processes of necroses formation. The content of phenolic compounds is positively correlated with the toxic elements - fluorine and aluminium and negatively with the macroelements - phosphorus, potassium and magnesium.

Five treatments were established: wood ash (10 000 and 5000 kg/ha), peat and wood ash mixture (10 000 and 5000 kg/ha) and control (unfertilized field). Results of analysis showed that the pH of peat in the cutaway peatland was before treatment 3.5 and it rose after fertilization by up to 0.7 units by the end of the first growing season. The treatment with 10 000 kg/ha of wood ash gave the best results: the annual height increment of Silver birches during the first growing season after fertilization was 4.5 times higher and that of Scots pines 1.1 times higher than control. In the second growing season after fertilization the increment was respectively 16.3 and 3.3 times higher than control. The root collar diameters of Silver birches were 4.4 time larger these of Scots pines 2.1 times larger than control. Scots pine needles were 2.2 times longer than control and the leaf area of the Silver birches was 6 times larger than control, which also shows a positive effect of fertilization. Peat ash treatment was also favourable, although its effect was much smaller than the effect of wood ash.

This paper explores the comparative analysis of the financial controlling, who is a result from the common controlling concept and the financial management. In the specialized literature, financial controlling is seen as an innovative approach to financial management. It is often presented as the most promising instrument of financial diagnostics. Generally speaking, financial controlling is seen as a process of managing the company`s assets which are valued in monetary measures. The difference between the financial management and the financial controlling is that the second covers all functions of management, analysis and control of finances, aiming at maximizing their effective use and increasing the value of the enterprise. Financial controlling is often seen as a function of the common practice of financial management. Its objective is to preserve the financial stability and financial sustainability of enterprises operating in a highly aggressive business environment.

The aim of the work is to establish effective state instruments of development of entrepreneurial activity in the agrarian sector of Ukraine. For the realization of the purpose was used a number of economic-mathematical methods of analysis by panel data of EU and OECD countries for the period 1986-2020: regression modeling of relationships between the total value of agrarian production and total support, rendered to agrarian sector, types and structural volumes of such support; regression dependence statistics, methods of comparative analysis and graphics analysis. The results allowed us to establish that the change in the total production value of the agrarian sector by 96,79% is determined by the types and structural volumes of state support provided to the agrarian sector. For the development of entrepreneurial activity in the agrarian sector of Ukraine it is advisable to activate state support of knowledge and innovation system, infrastructure of agrarian sphere and optimize measures of inspection and control, significantly prevail among the tools of domestic regulation of the agrarian sphere.

The article considers the probability of the intensity of the erosion process and the prerequisites for its mitigation and control. The results of the research prove that soil erosion is based on natural and anthropogenic factors. The main objectives of the study were to determine the amount and level of development of worn and erosion-prone soils in the foothills of the country, where it is very difficult to develop on the slope soils of Upper Shirvani. Therefore, in this connection, the tasks are solved, taking into account the requirements of preserving the ecological situation in the example of the Shamakhi district of the Upper Shirvan zone of the Republic of Azerbaijan, where the areas of its potential danger are identified and the preconditions for its prevention are given.

Fungus G. abietina is one of the most dangerous pathogenic fungi occurring in conifer plantations and Pinus species are especially at risk. Among pines, the most susceptible species is Austrian pine, and particularly endangered plantations are between 8 and 25 years of age. This fungus was found in Serbia and Montenegro on Austrian pine, Scots pine and spruce, but it was only in mountainous regions (Kopaonik, Vlasina, Goc, Durmitor). G. abietina forms both stages (anamorph and teleomorph) in its development. The imperfect form is far more significant for the infection process, i.e. the pycnidial stage and generally all infections are caused by conidia (pycnospores). Apothecia will be formed on the bark only two years after tree dying. In the severely infected plantations, all dead trees should be felled and removed, and the remaining trees should be treated with copper fungicides.

Importance. Despite the improvement of diagnostic methods and the introduction of new technologies in the treatment of pathology of the oral mucosa, it is difficult to achieve stable remission, since 70 % of cases are based on somatic and bodily suffering factors. The article presents data from a comparative analysis of the use of the traditional treatment regimen for patients with pathology of the oral cavity and the inclusion of the latest generation of antipsychotics in the treatment regimen. It was established that, when applied, a tendency towards normalization of psychological and autonomic status was observed. The inclusion of anxiolytics and antioxidants in the complex of general therapy for patients with pathology of the oral mucosa contributed to a more pronounced positive dynamics of achieving and prolonging the phase of remission. Objectives — to evaluate the effectiveness of introducing drugs of the latest generation of antipsychotics into the traditional treatment regimen for patients with pathology of the oral cavity. Methodology. Under our supervision, there were 30 patients aged 40 to 60 years with a diagnosis of pathology of the oral mucosa and pathology of the periodontium. All examined were divided into 2 groups: the main (15 people) and control (15 people). Results. Clinical well-being, manifested in a subjective decrease in pain in the tongue, feelings of rawness, tingling, numbness, awkwardness, in the tongue, was noted already at the 5th visit in 67 % of patients of the main group, while in the control group in 17 % of patients. Conclusions. The inclusion of anxiolytics and antioxidants in the complex of general therapy for patients with pathology of the oral mucosa contributed to a more pronounced positive dynamics of achieving and prolonging the phase of remission. Our data allow us to implement this treatment regimen in practical healthcare.
