With the high perception of visitors and the value of economic use of Situgunung Nature Tourism objects, a more professional management is needed without reducing the concept of natural sustainability.

Comparative characteristic between European and Ukrainian legal mechanisms for regulating the discharges of pollutants

The article examines and compares the structures and basic norms of legal mechanisms for controlling the discharge (CD) of polluting substances (PS) from point technogenical sources into surface waters of EU and Ukrainian legislation. To analyze the systemic construction of the European CDPS and a meaningful study of its main elements, a tool has been identified, which is the chain of spreading of restrictive (limiting) legal influence, its legislative links and regulative norms. The structure and composition of this chain of European CDPS are identified, PS flows and information links between restrictive standards are studied. It is noted that the main branches of the structure of the European CDPS are technological and environmental legal influences. The second branch is additional. It complements the first one for some priority substances and it uses to limit the discharge of PS properties of the area of the water body which adjacent to the discharge of PS, the so-called mixing zones (MZ). The place and significance of the CDPS subinstitution in the European water legislation are investigated. The peculiarities of the European regulatory standards of the CDPS are determined. The comparison of the European and Ukrainian CDPSs using the scale of features that characterize the links in the chain of limiting legal influence is fulfilled. The concordance of the features of the Ukrainian CDPS to the European one was assessed by the categories: “fully compliant”, “partially compliant”, “does not contradict”, “does not comply”, “not regulated by EU legislation”. The distribution of concordance assessments testifies to the fundamental difference between the European CDPS and the Ukrainian one. The most important differences of legal discordance are investigated. It is concluded that the main difference between the two CDPS subinstitutions is that Ukrainian regulation is based only on the economic use of the assimilative capacity of the MZ. It is emphasized that the concept of MZ for more than 60 years of its actual use has not received proper legal justification in Ukrainian law. In contrast to the Ukrainian regulation, the main influence of the European CDPS is aimed at directly limiting the sources of PS. The priority changes in the water legislation of Ukraine for the implementation of the requirements of the EU legislation on CDPS, have been proposed.

Improving the methodology of cadastral land assessment

Methodological tools for improving the existing methods of cadastral land valuation are described. The basis of its development and improvement of objectivity is the ecological paradigm, the conceptual novelty of which consists in the cost accounting of changes in productive properties and at the same time the ecological state of arable land as a result of annual cycles of economic use. A conceptually new way of forecasting the potential costs associated with the cultivation of crop products has also been developed. It is based on the economic and mathematical models created by the author.

Efficacy of Cicer arietinum L. & Vigna mungo L. in remediation of Hexavalent Chromium

Hexavalent Chromium is a major soil pollutant; thus, its remediation from soil deserves due attention. Phytoremediation is an area of active current research which is eco-friendly and economic. Use of leguminous plants for phytoremediation will improve soil quality, fertility and nutrient balance and would help in restoration of natural soil ecosystem. The present study focuses on the use of two commonly growing legumes; Cicer arietinum (RP1) and Vigna mungo (RP2) to explore their remediation potential towards Cr(VI) with concentration ranging from 100-900 mg kg−1 with the growth up to three weeks and were assessed for remediation potential and toxicity parameters. Higher percentage of decrease in root and shoot length was observed in RP2 as compared to RP1. Chlorophyll content was also found to be decreasing with increasing Cr stress in both the species. RP2 recorded higher BCF than RP1. Highest bioaccumulation factor 4.32 was observed in RP2 at 400 mg kg−1 concentration. Translocation factor >1 was observed in both the plants with highest as 1.67 at 600 mg kg−1 in RP2 and 1.93 at 400 mg kg−1 in RP1. Remediation percentage of 72.25% in RP2 at 600 mg kg−1 and 73.13% at 400 mg kg−1 in RP1 was observed. Both the plants showed high tolerance and remediation potential towards Cr(VI) therefore has a great phytoremediation prospect, however, RP2 can be preferred over RP1.

Genetic factor affecting the milk production of mares

The article presents the results of studies to establish the influence of the record productivity of mothers’ mares on milk yield and the duration of productive life of mares-daughters of the Lithuanian heavy draft breed. It was found that the high level of milk productivity of mothers during the period of highest lactation (up to 4000 kg of milk) enabled their daughters to become leaders already during the first lactation. With an increase in the record milk yields per lactation in mothers, the heritability coefficient in mother-daughter pairs decreased and turned into negative values. The daughters of mares with record milk yields of up to 8000 are the most dairy among their contemporaries. The research results indicate that intensive milk production of mares during the first lactation can cause a reduction in the terms of their economic use due to the large loads on the developing fragile animal organism. The highest rates of productive life, number of lactations and life-long milk yield were obtained from daughters whose mothers had record milk yields per lactation from 7000 kg to 8000 kg of milk.

Influence of the type of higher nervous activity on milk yield and the productive longevity of mares

The presented work is the result of studies of the influence of the type of higher nervous activity on the dairy productivity of mares of the Russian heavy draft horse breed on stationary koumiss farms. To determine the types of higher nervous activity, a motor-food technique developed by the All-Russian Research Institute of Horse Breeding was used. The milk yield was counted at animals for the first lactation, for the highest lactation, on average for one lactation and a lifelong milk yield of mares. The milk yield on average for lactation is almost the same in mares with a strong balanced mobile type and with a strong unbalanced type of higher nervous activity. Animals of a weak type and a strong balanced inert type of higher nervous activity lag behind them in this indicator by 11-13%. Horses with a strong balanced mobile type, a strong unbalanced type and a weak type of higher nervous activity are most suitable for the duration of economic use and lifelong milk production. The mares with a strong balanced inert type of higher nervous activity are the least productive in terms of duration of economic use and lifelong milk yield on koumiss farms.

Ecological-and-economic aspects of city-planning

The purpose of this research is to consider ecological-and-aspects of the land use during arrangement and planning of the urban areas on the basis of the assessment of city-planning components of various districts of the city. The authors offer some measures for the improvement of nature protection activity in the structure of the urban area management. The factors, determining planning of the city structures, key indicators of information support for the adoption of the city-planning decision, the principles of engineering-and-ecological zoning were revealed in the articles. The authors offered to carry out management of the territory and granting the land plots step by step, for the purpose of their effective ecological-and-economic use. The provisions, offered by the authors in this article, can be applied for ecological-and-economic justification of projects of the use of city lands as well as for the development of methodical recommendations on the effective arrangement of the built-up territories.

Selection and breeding work with a modern population of Sarboyan carp

Carp breeding in Western Siberia has been going on for about 1960. Here two breeds of Sarboyan and Altai mirror carp were bred and put into economic use. The Sarboyan carp is a cross with 1/8 of the blood of the Amur carp. The Sarboyan carp has now disappeared in the fish farm, there are its descendants who have not been subjected to selection for 4 generations. To work on the selection of a new intra-breed type, specimens corresponding to classes 1 and 2 were selected from the head reservoir of the fish farm. Specimens of class 1 accounted for 2.6% of all selected fish. The analysis of the exterior showed that as a result of the lack of selection and mating disorderly, the physique of the fish changed. It deviated and is closer to the wild Amur carp. In males, the length index increased by 21.30%, the body became longer and smaller. In females, the same changes are observed in exterior, in addition, there is a decrease in fertility, since in the studied population the correlation between progenity and fecundity is 0.42-0.72. The relative growth of the main exterior features has decreased.

INDIVIDUAL AND GROUP INDICES OF VELVET ANTLER PRODUCTION OF MARALS FOR THE PERIOD OF THEIR ECONOMIC USE

Maral breeding is a promising direction of animal hus-bandry in the Altai Region and the Republic of Altai. Breed-ing of highly productive maral stags is based on the proper organization of breeding work which is not possible without an accurate evaluation of individual and group indices of velvet antler weight. In this regard, the research goal is to study individual and group indices of velvet antler produc-tion of marals for the period of their economic use depend-ing on the age. It was found that the velvet antler weight increased by 6.3 kg over the entire study period, and there was a decreasing tendency of the productive index in thir-teen-year-old marals by 800 g. It was found that in the maral stag herd in 2021, the maral stag born in 2008 with velvet antler weight of 18.8 kg became the record holder. The main criteria for culling were decreased velvet antler production and fatness; the age of those animals was from eleven to fourteen years. In this regard, it was found that individual highly productive thirteen-year-old maral stags could consistently produce high-weight velvet antlers dur-ing the period of their economic use. To improve the quali-tative composition of marals, at breeding time, it is neces-sary to evaluate and select high-productive stags from six to twelve years old individually in dynamics and cull low-productive ones regardless of age.

The remarkably frequent use of EQ-5D in non-economic research

Introduction EQ-5D is an instrument which has been utilized for a variety of purposes, including in health-economic appraisals as an input into quality-adjusted life year (QALY) calculations. Indeed, it is the most-widely applied instrument for health-economic appraisal worldwide, and is recommended for use in QALY calculations by many national Health Technology Assessment (HTA) agencies. There is also a growing body of evidence for its usefulness in a variety of settings other than economic appraisals, but such use has not been well-documented. This study addresses this issue and documents how EQ-5D has been applied in both the non-economic and economic contexts. Methods The PubMed database was searched using the terms ‘EQ-5D’, ‘EQ-5D AND cost’, and ‘EQ-5D AND cost AND QALY’ from 1 January 1980 to 31 December 2019. We concentrated on 2019 publications for more detailed analyses. All the data collected for 2019 were downloaded and collected in EndNote. For 2019 only, we classified economic and non-economic use based on the inclusion of ‘cost’. We also checked by manual inspection whether the search terms were suitable in correctly identifying economic and non-economic use. Variants of the non-economic use of EQ-5D were classified as follows: (a) as a quality of life outcome measure; (b) as a tool for methodological research; (c) methodological issues of EQ-5D itself; (d) comparisons with other quality of life questionnaires; (e) mapping studies; (f) value sets; (g) alongside costs but no QALY calculated; and (h) other. Results The first publication found was from 1990. Up to and including 2019, 10,817 publications were identified, of which more than two in three did not contain any reference to costs or QALYs. In 2019, a total of 1409 manuscripts were identified, of which 239 were specifically for EQ-5D-5L. Four hundred and seven (28.9%) included some form of ‘costs’ and 157 (11.1%) both ‘costs’ AND ‘QALYs’ terms. For EQ-5D-5L, the corresponding numbers were 104 (43.5%) and 29 (12.1%), respectively. After manually checking all the 1409 papers, three were duplicated records, which were omitted. In the remaining 1406 papers, only 40 (2.8%) contained the term ‘cost’, but not ‘cost per QALY’, and only 117 (8.3%) were identifiable as economic evaluations using the term ‘cost per QALY’. Most non-economic use of EQ-5D was as a quality-of-life outcome measure (72.8%). Other applications were: as a tool for methodological research (6.7%); comparison studies (3.7%); EQ-5D methodological issues (3.5%); containing costs but not QALYs (2.8%); mapping (1.3%); value sets (0.4%); and other papers (0.4%). Conclusions The majority of the studies retrieved, covering a wide variety of research areas, reported upon the non-economic use of EQ-5D. Despite being the most-used instrument worldwide for QALY calculations, economic appraisal accounted for only a small, but important, part of published use.
