The most widespread magnolia on the Southern coast of the Crimea and, in particular, in the Arboretum of the Nikitsky Botanical Gardens is the evergreen Magnolia grandiflora L., introduced in 1817. Currently, 28 generative specimens of Magnolia grandiflora of different ages grow in the Arboretum, including garden forms with different vital state. There are very few data on the relation of this species to soil conditions. For this reason, we have studied the influence of edaphic factors on the vital state of Magnolia grandiflora growing in the Arboretum of the Nikitsky Botanical Gardens. A number of limiting edaphic factors have been identified, the main of which is the high skeletal structure of the soil. The humus reserves in the soil have a positive effect on the vital state of trees. A high level of agricultural technology is the main method of improving the vital state of Magnolia grandiflora .

As a result of instrumental diagnostics of the state of trunk wood, the level of phytopathogenic damage of the most old-age specimens of Magnolia grandiflora L. in the Arboretum of the Nikitsky Botanical Gardens is estimated. Digital two-dimensional images of the trunk wood were obtained, and the relative indicators of the degree of its destruction were characterized. The results of the research allowed us to identify some patterns in the nature of the distribution of destructions in the trunk wood of M. grandiflora . It was found that of the six studied specimens of M. grandiflora , the greatest destruction of trunk wood was found in two 130-year-old trees growing in The Upper Arboretum Park. There was no correlation between the presence and degree of destruction of M. grandiflora trunk wood and the age of the trees examined. The use of the ultrasound tomography method expands the possibilities of diagnostics of phytopathogenic lesion of the trunk wood. The combination of visual assessment and instrumental diagnostics of trunk wood allows us to obtain more complete information about the vital state of trees.

В статье приводятся результаты исследований 2017-2019 гг., проведенных в почвенно-климатических условиях Крыма, по контролю неинфекционного хлороза винограда на технических сортах путем применения железосодержащих минеральных удобрений. Экспериментально доказано, что использование препаратов Омекс Микромакс, Секвестрен Турбо и Хелат Fe при внекорневых подкормках виноградной лозы сортов Пино нуар и Алиготе привели к существенному снижению распространения и развития хлороза, в среднем на 10,5 и 5% соответственно. В ходе настоящих исследований при высоком уровне развития неинфекционного хлороза доказано положительное влияние минеральных удобрений на продуктивность виноградных растений: четырехкратное использование препарата Омекс Микромакс (сорт Пино нуар) позволило увеличить урожайность винограда на 10,9%; двукратное применение удобрения Секвестрен Турбо (сорт Алиготе) - на 12,9% в условиях Юго-западного Крыма. В условиях Южного берега Крыма внекорневые обработки микроудобрением Хелат Fe в фенологические фазы «после цветения» и «мелкая горошина» способствовали повышению урожайности винограда сорта Алиготе на 7,4%. The article presents the results of studies, conducted in soil-climatic conditions of the Crimea in 2017-2019, on the control of non-infectious chlorosis of wine grape varieties by using iron-containing mineral fertilizers. The use of Omex Micromax, Sequestrene Turbo and Chelate Fe preparations for foliar dressing of ‘Pinot Noir’ and ‘Aligote’ vines led to a significant decrease in the expansion and progression of chlorosis, on average by 10.5 and 5%, respectively. During the studies and considering the high level of development of non-infectious chlorosis, the positive effect of mineral fertilizers on the productivity of grape plants was proved: four-time use of preparation Omex Micromax (‘Pinot Noir’ variety) increased the crop yield of grapes by 10.9%; two-time application of Sequestrene Turbo fertilizer (‘Aligote’ variety) - by 12.9% in the conditions of the south-west part of Crimea. In the conditions of the South Coast of Crimea foliar treatments with micronutrient fertilizer Chelate Fe in phenological phases “after flowering” and “berries pea-size” contributed to an increase in the yield of ‘Aligote’ grape variety by 7.4%.

Background: In recent years, great progress has been made in reducing the high level of malaria suffering worldwide. There is a great need to evaluate drug resistance reversers and consider new medicines against malaria. There are many approaches to the development of antimalarial drugs. Specific concerns must be taken in to account in these approaches, in particular there requirement for very in expensive and simple use of new therapies and the need to limit drug discovery expenses. Important ongoing efforts are the optimisation of treatment with available medications, including the use of combination therapy. The production of analogs of known agents and the identification of natural products, the use of compounds originally developed against other diseases, the assessment of overcoming drug resistance and the consideration of new therapeutic targets. Liver and spleen are the important organs which are directly associated with malarial complications. Aim: An analysis the Activity of Adenosine Triphosphatase, Aryl Hyrocarbon Hydroxylase Enzymes and Malondialdehyde in spleen Explant Culture. Objective: To determine in-Vitro Effect of Chlorquine and Picroliv on Plasmodium Berghei Induced Alterations in the Activity of Adenosine Triphosphatase, Aryl Hyrocarbon Hydroxylase Enzymes and Malondialdehyde in spleen Explant Culture. Material and method: 1-Histological preparation of spleen explants for paraplast embedding 2-Biochemicalstudies (Enzymes (Atpase, ALP&GST) and the level of protein, Malondialdehyde (MDA). Result: Splenomegalyis one of the three main diagnostic parameters of malaria infection besides fever and anaemia. Many enzymes present in the liver and spleen may also be altered or liberated under different pathological conditions. Enzymes (ATPase, ALP&GST) and the level of protein, Malondialdehyde (MDA) content was found to increase in the liver and spleen explants during malarial infection. In the liver and spleen derived from parasitized CQ treated animals, the activity of all the above enzymes (ATPase, ALP&GST) and the level of protein & MDA of liver/spleen reversed towards the normal for all the 4or3 days of incubations. Picroliv efficacy decreased with the increment of parasitaemia and at 60%parasitaemia. Conclusion: Alkalinephosphatase (ALP) was found to increase with increasing parasitaemia. After the addition of Picroliv to the medium, a decrement in the activity was observed up to day 4 of culture.A similar positive effect of Picroliv was observed on the ATPase and ALP activity of spleen explants.DNA and protein contents also increased in the parasitized liver cultured in the presence of picroliv.On the contrary, in the spleen explants DNA, protein and MDA content were found to decrease after Picroliv supplementation to the culture medium.

During the operation of the negative electrode, some critical processes take place, which are limiting factors for the operation of lead–acid batteries. To improve the efficiency of the negative active material and minimize these processes, external application of multivector field is proposed. Two applications of the multivector field are studied: during negative paste preparation and during formation. It is established that, when applying multivector field during negative paste preparation, the chemical processes proceed more efficiently. The results are better phase composition and crystallinity of the cured paste, thus increasing the capacity of the consequently built lead batteries by 12% on average. The application of a multivector field during the formation of negative active materials in lead batteries has a positive effect on the skeletal structure, the size and shape of the Pb crystals. This ensures longer service life, which is confirmed by the 17.5% Depth of Discharge continuous tests on 12 V/75 Ah batteries. The batteries formed under the influence of external multivector field showed 20% longer cycle life. Based on the experimental result, a most probable mechanism of the influence of the multivector field on the chemical and electrochemical processes in lead batteries during negative paste preparation and formation of negative active masses is proposed.

The crystallographic orientations of echinoderm skeletal elements can supplement standard morphological comparisons in the exploration of echinoderm evolution. At a coarse scale, many echinoderms share a crystallographic pattern in whichcaxes radiate away from the axis of pentaradial symmetry. Within this common pattern, however,caxes of different taxa can differ dramatically in their degree of variability, angles of inclination, and relationships to the external morphology of skeletal elements. Crystallographic data reflect a variety of taxon-specific influences and therefore reveal different information in different taxa. In echinoids, orientations ofcaxes in coronal plates correlate well with high-level taxonomic groupings, whilecaxes of apical plates record modes of larval development. In blastoids,caxes of radial plates have a structural interpretation, with thecaxis oriented parallel to the orientation of the surface of the radial plate during its initial growth stages. In crinoids,caxes do not correlate with taxonomic group, plate morphology, or developmental sequence, but instead correlate with relative positions of skeletal elements on the calyx. Although their full potential has yet to be explored, the varied crystallographic patterns in echinoderms have been used to clarify skeletal structure, characterize developmental anomalies, and infer homologies of skeletal plates both within specimens and between groups. A axes are less constrained in their orientations thancaxes and offer less promise of revealing novel paleobiological information.

This article describes the results of comparative analysis of the dynamics of incidence of pulmonary tuberculo-sis (TBP), extrapulmonary extrarespiratory tuberculo-sis (TBER) and respiratory extrapulmonary tuberculosis (TBREP) in St. Petersburg (Leningrad) from 1970 to 2019. Throughout the 50 years of observation, epidemiological situation for TBP, especially for TBER, hasmuch improved, with incidence of the latter going down 30 times. Five stages (decades) were identified, within which the factors demonstrate practically the same impact, the growth rate of indicators was calculated for each stage (the value of indicators at the beginning of each stage taken as 100%).The first stage was a simultaneous reduction in the inci-dence rate in all categories of TB localization against the background of socio-economic factors positive effect and organization of effective and comprehensive an-ti-TB measures. In the second stage (1980ies, a period of growing socio-economic problems), the positive dynam-ics of TB incidence stopped and switched to stabilization at a low level. Indicators became more volatile, while TB dynamics by localization more and more desynchro-nized. Тhe third stage (1990iеs, a period of social and economic crisis) was char-acterised by a sharp increase of TB incidence, especially TBREP, with a switch to stabi-lization at a high level. The fourth stage (2000 through 2009, the beginning of TB control system restoration) demonstrated the indicators’ dynamics desynchroniza-tion: the incidence of TBP and TBREP has stabilized, and TBER continued to decline. The fifth stage (2009 through 2019, complete restoration of TB control system) showed a steady trend of incidence rate reduction and return of uniformity in incidence rate of various localizations.There is no increase in the proportion of extrapulmonary TB expected for the incidence decline. TBER incidence had been declining in most stages, with the exception of the 90ies, which could be explained by substandard work in identifying patients, and the rarity of TBER etiological verification. It is necessary to raise the clinical awareness of narrow specialists and general practitioners in the di-agnostic problems associated with TBER.The coincidence of the rate of TB incidence decrease in main localizations in the 1970ies and 2010s proves that a comprehensive state strategy to combat tuberculosis can provide a high rate of TB incidence decrease in various social layers with positive social and economic conditions of life of the population.

This study analyzes corruption and economic growth. The method of analysis uses literature studies. This literature study was carried out by searching scientific research articles about corruption through Google Scholar and journals about corruption. After the identification of several articles, the results show different results about the effect of corruption on economic growth. From each journal shows Corruption has a negative effect on economic growth in Indonesia and those that have a positive effect. This shows several factors that underlie the influence of corruption on economic growth, namely due to cultural differences, policies, economic freedom and the rules of each region. The diversity of each region in Indonesia makes a different level of influence of corruption so that if a region has a high level of economic freedom and rules and bureaucracy that are not difficult, corruption has a positive effect on economic growth. In general, the effect of corruption on economic growth is negative, where the cleaner the region or region is from corruption, the more it will encourage the growth of the region.

The article presents the results of a long-term research on the introduction study and evaluation of cultivars of tea-hybrid roses introduced and selected by the Nikitsky Botanical Gardens to determine the possibilities of their use in floriculture of the Southern Coast of the Crimea. The research was conducted in the period from 1955 to 2014. The material for the study was 679 cultivars of garden roses from the tea-hybrid garden group of the collection of the Nikitsky Botanical Gardens. As a result of a comprehensive study, 400 cultivars are recommended for use in the floriculture of the Crimea. The main options for this use becomes the growing of tea-hybrid roses in the open ground for gardening purposes in bush and tree-shaped forms, as well as the growing cultivars for cutting in both open and protected ground. The biological features of the cultivars, which determine the possibility of different types of the use and the cultivars, that have these features were identified: 400 cultivars were recommended for use in landscaping in bush form, 45 cultivars - also in tree-shaped form, 226 cultivars are promising for cutting in the open ground and 107 cultivars - for forcing and cutting in greenhouses. The main methods of propagation of cultivars of tea-hybrid roses under the conditions of the Southern Coast of the Crimea are budding and rooting of green and hardwood cuttings. The optimal timing for propagation by each of these methods is indicated. The best rootstocks for budding were identified, depending on the type of their use in floriculture.
