This study aimed to determine the number of taxa that will be discovered in Uzbekistan from 1993 to 2023. As a result of the analysis of various scientific journals, monographs, and flora books from 1993 to 2023, it was found that 114 new vascular plant taxa were described for Uzbekistan during this period: 1 new genus, 80 new species, 28 new combinations, 2 new subspecies, 4 new names, and 1 new variety. The process of discovering new vascular plants in Uzbekistan will continue in coming years. In the process of preparing a new national flora of Uzbekistan, it is very important to study the composition of the national flora and conduct taxonomic research. Major work is being carried out in this regard, especially over the next 10 years. Sometimes, newly discovered taxa by scientists are cited in local scientific journals or monographs. This creates difficulties in disclosing these taxa to the global scientific community. From these results, it can be concluded that if newly discovered taxa are regularly included in scientific databases (such as IPNI), it will be easier for the world community to determine the floristic composition of individual countries or specific geographical regions.
This article aims to develop scientific and methodological proposals and practical recommendations to improve the methodology for assessing the effectiveness of investment activities of insurance organizations. The work uses scientific methods for studying the processes of economic reality - systematic analysis, generalization, grouping, observation, logical and comparative methods of analysis, abstract logical thinking, comparative analysis, mathematical modeling, econometric analysis, actuarial calculations, etc. Based on the systematization of information on investment activities, investment policies, and experience of insurance companies in developed countries, the use of statistical and mathematical methods of data processing, diversification of the financial and investment activities of insurance companies, recommendations, and indicators used to assess the effectiveness of insurance companies have been developed, identified and classified into individual areas, external and internal factors influencing the financial stability of insurance organizations, the possibilities of increasing the amount of profit they receive are substantiated, proposals are given to improve the methodology for managing the investment portfolio of insurance companies, and prospects for the development of modern options for investment activities are identified. The effective organization of the mechanism for monitoring the financial stability of insurance companies allows for minimizing the level of missed opportunities in achieving the company’s strategic goals based on econometric forecasting of financial stability and assessment of financial risks. In order to strengthen the role of insurance companies in increasing the investment potential of the country Uzbekistan, it is proposed to develop the securities market, the market for government, corporate, and municipal bonds.
The article examines the features of the criteria for the strength of continuous encryption algorithms. The general properties of the models of algorithms of the continuous encryption class are revealed. On their basis, the corresponding requirements are formulated in the form of criteria that determine the necessary conditions for cryptographic resistant. The totality of these criteria is formulated as a statement.
This article provides information on the methods of obtaining activated adsorbents based on oil-oil waste gossypol tar and local benonites and their various physical properties. In addition, the effect of temperature change on the yield of activated adsorbents from gossypol resin was analyzed. As a result, when Logon bentonite is modified with activated gossypol resin, the hydrophilic properties decrease and the hydrophobic properties increase. Compared to coke obtained from gossypol, it was known that the density of adsorbents obtained as a result of its modification with local bentonite increases. At the end of the study, it was concluded that by adding bentonite as a binder to gossypol resin, its strength increases several times.
