Update on the current situation with respect to COVID-19 in UK.
Authors: Khan Aamir
Published: April 2021

Currently, UK is experiencing a second wave of the Covid-19 virus. A new strain of the Covid-19 coronavirus has emerged in the UK, which is spreading more quickly than previous strains. The relative hazard of death within 28 days of a test in infected people compared to people with the original variant was 1.35 (95% confidence interval 1.08 to 1.68). That suggests it is more contagious. So, it's particularly important to be strict about social distancing, wearing a face mask in enclosed spaces, and frequently washing your hands. There is no evidence to suggest whether this strain is more deadly than before. Initial findings from a study conducted by Imperial College London and Ipsos MORI show infections increased by 50% from early December, with 1 in 63 people infected. The interim findings from the eighth report of Real-time Assessment of Community Transmission (REACT), one of the country's largest studies into COVID-19 infections in England, suggest that infections in England have plateaued at the highest level with suggestions of a potential uptick. The report does not yet reflect the impact of national lockdown.

Authors: Zehra Nazneen , Naz Lubna
Published: April 2021

Background: Carica papaya seeds are regarded as waste or by-product of the fruit since it is the inedible part of the plant. However, it holds a diversified range of phytochemicals that anticipate their therapeutic role in different types of ailments. The seed extract has been proven for the presence of multiple health benefiting contents and some toxic agents. Studies evaluating the toxicity of the Papaya seed extract are still scarce to support its safe use as a therapeutic agent. Therefore, the undertaken study is to explore the safe dose of the aqueous extract of Papaya seeds.

Methodology: This study is designed to examine the toxic potential of Papaya seed aqueous extract on Wistar rats for 42 days by oral administration at dose regimens of 100, 200 and 400 mg/kg body weight in the liver. The groups (n=6) allotted include control untreated and group I (100 mg/kg), group II (200 mg/kg) and group III (400 mg/kg). The liver toxicity was assessed using liver enzymes as toxicity markers. The morphology of liver cells was observed by histology.

Results: Our results showed no mortality or signs of toxicity. The body weights were observed to be declining with increasing doses. However, other biochemical parameters displayed no significant alterations in treated groups as compared to the controls.

Conclusion: This study supports the evidence that chosen doses of aqueous extract of papaya seeds are safe for normal liver functioning. This evidence endorses the use of the extracts of the seeds as a therapeutic intervention.

Authors: Abbas Jaffri Samar , Syed Muhammad Irfan  , Sultana Sadia , Syed Muhammad Usman  , Nadeem Sheeza
Published: April 2021

Background: Beta-thalassemia is an autosomal recessive hemoglobinopathy with frequent skeletal complications, often debilitating in adolescent patients. We aim to evaluate the bone mineral density (BMD) by dual-energy x-ray absorptiometry (DEXA) and ascertain osteoporosis/osteopenia frequency in patients with β-thalassemia major.

Methodology:  In this cross-sectional study, 36 adolescent patients with β-thalassemia major were enrolled from June 2015 to March 2017.  BMD was measured in the anteroposterior lumbar spine (L1-L4) and femoral neck by DEXA. For the biochemical estimations, blood and urine samples were obtained and analyzed. The results of a bone density test were presented as T and Z scores.

Results: There were 20 male and 16 female patients with a mean age of 21.33 ± 3.7 years. The mean bone mineral content (BMC) was 20.10 ± 6.0 gm, and the mean BMD was 0.65 ± 0.07 gm/cm2. The mean T score was -3.17 ± 1.04, and the Z score was -3.06 ± 1.06. All patients had low BMD, as depicted by their T or Z scores. The reported frequency of osteoporosis and osteopenia was 77.7% and 22.2%, respectively.

Conclusion: All Beta-thalassemia major patients had low BMD with a remarkable incidence of osteoporosis. It is recommended to perform an annual BMD among thalassemic patients to prevent fatal consequences and achieve an optimal bone density among such patients.

Published: April 2021

Background: Every year, 2.7 million stillbirths occur worldwide, mostly in developing countries. The United Nations Sustainable Development Goals (SDGs) include reducing childhood mortality under five years of age. Perinatal death audit is an intervention to reduce preventable neonatal mortality. The aim of this study was to determine the Perinatal Mortality Rate (PMR) and the factors responsible for perinatal deaths at a Tertiary Care Hospital in Karachi-Pakistan.

Methodology: This was a prospective study of all the stillbirths and early neonatal deaths in Abbasi Shaheed Hospital Karachi, Gynecology Unit I. Details of each perinatal death were filled in the standard form. We used Aberdeen Obstetric classification to classify causes of perinatal deaths.

Results: There were 1627 deliveries and 43 perinatal deaths during the study period. Our study's perinatal mortality rate was 27.14/1000 births, and the stillbirth rate was 13.25/1000 births. Antepartum hemorrhage (APH), pregnancy-induced hypertension (PIH) and anemia were the common causes of perinatal deaths.

Conclusion: Antepartum hemorrhage, pregnancy-induced hypertension and anemia are the leading causes of perinatal deaths. Most of these complications can be reduced by educating women and providing effective antenatal care.

Published: April 2021

Background: Developing countries encounter a change in lifestyle, which establish novel risk factors for cardiovascular disease, leading to an explosion in cardiovascular disease risk all through the developing nations. Dietary therapies and physical activity are the first lines of treatment in hyperlipidemia, and several dietary components with such effects have been identified. This study is intended to assess the potential of Salvia Rosmarinus (SR) leaves powder consumption on diet-induced hyperlipidemia. The main objective of this study is to show that plant products could be equivalent to the available medicines.

Methodology: In this experimental study, 4 to 5 weeks old mice were used with an average weight of 200 gm. Baseline values of all parameters were observed & animals were administered an atherogenic diet for two weeks. 0.11 gm/day rosemary leaves powder was fed by these hypercholesterolemic rats for another two weeks. At the end of the experimental duration, blood samples were collected and evaluated for alterations in plasma lipid profile, glucose, liver enzymes and kidney biomarkers. 

Results: According to the research results, oral supplementation of 0.11 gm/day rosemary effectively reduced dietary hyperlipidemia in experimental mice. Significant (p<0.05) reduction in body weights, total plasma cholesterol (TC), glucose, alkaline phosphate (ALP) and urea levels were analysed, and a non-significant decrease in triglyceride (TG), low-density lipoprotein (LDL), uric acid and creatinine was observed. 

Conclusion: It is concluded that Rosemary can be utilized beneficially for primary prevention trials of cardiovascular disease, but of course, further investigations are required to find out an effective dose of rosemary.

Authors: Ahmed Ibrar , Sabir Ali Sobia , Ali Zafar , Muhammad Nawaz  , Ghaffar Tahir
Published: April 2021

Background: Diabetic ketoacidosis (DKA) is an acute metabolic healthcare crisis in patients with diabetes mellitus. The current study aimed to compare the effectiveness of rapid-acting insulin analog administered subcutaneously with regular insulin infused intravenously among the DKA patients.

Methodology: In this prospective open labelled study, 100 consecutive DKA patients were randomly assigned to two groups. Group 1 patients were admitted to the intensive care unit (ICU) and treated with intravenous regular insulin infusion. Group 2 patients were managed in the emergency medical ward with subcutaneous rapid-acting insulin. Response to the therapy was assessed by the follow-up investigations of the biochemical parameters, including blood glucose concentration, serum ketones, pH, serum electrolytes including bicarbonates, sodium and potassium concentration until the resolution of DKA. Furthermore, the overall duration of therapy (blood glucose level < 250 mg/dl), time and amount of insulin administered until the resolution of DKA, were also assessed.

Results: The baseline clinical and biochemical parameters were similar between the two treatment groups except for blood glucose and sodium concentration. The mean random blood sugar (RBS), acid-base parameters and concentration of ketone bodies were significantly improved from admission until the resolution of DKA. There was no significant difference in the duration of therapy (p=0.07). While the time and amount of insulin therapy required until resolution of DKA were significantly reduced among the patients treated subcutaneously with rapid-acting insulin, i.e. 16.36 ± 6.92 hrs and 59.28 ± 30.05 units (p<0.05).

Conclusion: The patients with less complicated DKA can be managed with rapid-acting insulin analog in the medical wards obviating the need for admission to the ICU. With relatively better outcomes, it is an effective alternative to regular intravenous insulin infusion for DKA resolution.

CONSIDERING THE STATE OF THE UKRAINIAN ECONOMY IN THE ENTERPRISES FINANCIAL SUSTAINABILITY MODELING
Authors: Debunov Leonid , Yakovenko Aleksandr
Published: April 2021

Construction of a model for predicting the bankruptcy of the enterprise is an urgent and popular task. Using this model will provide an opportunity to make quick and accurate assessment of financial sustainability, predict possible bankruptcy advance and take the necessary action to avoid it. Obviously, bankruptcy can occur both under the influence of internal factors (in particular, financial management errors) and when the economic environment changes. The inclusion of all possible en-vironmental factors influencing into the model is a difficult task and causes an over-load of such a model with a large number of input signals. A more realistic option is to build a model using internal financial indicators only, but under a relatively con-stant external environment. The subject of the study described in the article is the general homogeneity of the Ukrainian economy over time in the context of the possibility of using companies’ reports for these periods to build a neural network model of financial sustainability of enterprises using only internal financial indicators. To separate stable periods from unstable ones, a review of the dynamics of macroeconomic indicators of Ukraine for the period 2010–2019 is used. Graphical analysis of the dynamics of macroeconomic indicators is used as a methodology. The purpose of this study is to identify periods of Ukraine’s economy, the conditions of which are quite stable to take reports of enterprises of these periods for a dataset formation. The article considers the dynamics of the following indicators of Ukraine’s economy: gross domestic product, hryvnia exchange rate, employment, consumer price index, total net profit (loss) of enterprises by size of enterprises, levels of profitability of operating activities, foreign trade indicators by geographical areas (imports and exports of goods and services) etc. The study pays special attention to the economic crisis of 2014–2015 and to changes in the economic environment, which distinguish the conditions before and after the crisis. The main conclusions of the article are the recognition of the existence of crisis phenomena in the period 2014–2015 and the recognition of the difference between the post-crisis period and the pre-crisis period. In order to build an up-to-date model of financial sustainability, it is recommended to use report data for periods not earlier than 2016.

Published: April 2021

Alat-alat paleolitik seperti yang ditemukan pada aliran Sungai di lingkungan Pegunungan Serayu di Wilayah Kabupaten Banyumas yang terdiri dari kapak perimbas, kapak penetak, dan serpih merupakan alat yang bersifat teknis yaitu peralatan yang digunakan dalam kehidupan sehari-harinya. Hingga saat ini diyakini bahwa jenis artefak tersebut berkaitan dengan aktivitas perburuan dan pengumpulan makanan manusia pendukungnya. Fungsi masing-masing tipe alat-alat paleolitik tersebut secara pasti berkaitan dengan aktivitas tersebut belum dapat diketahui. Berdasarkan ukurannya, diperkirakan alat yang cukup besar dipergunakan untuk pekerjaan yang cukup berat seperti untuk memotong dan membelah benda-benda yang cukup keras. Sementara alat-alat yang beruk:uran relatif kecil dan tipis digunakan untuk memotong, mengiris, maupun menyayat benda-benda yang cukup lunak. Ada kemungkinan bahwa alat-alat paleolitik tersebut tidak berfungsi spesifik namun multi fungsi. Disamping berfungsi langsung sebagai alat perburuan, pengumpulan dan pengolahan makanan, alat-alat tersebut juga digunakan untuk membuat alat lain dari bahan berbeda, seperti kayu atau bambu misalnya.

Strategi yang diterapkan oleh para tokoh penyebar Islam, di daerah pesisir utara Jawa berbeda dengan strategi yang diterapkan di beberapa daerah di pedalaman Jawa, yaitu strategi perdagangan merupakan langkah yang dominan, disamping juga dilakukan dengan pendidikan, perkawinan dan rnengadopsi kesenian lokal dengan dimasuki muatan-muatan Islam. Akan tetapi pada periode berikutnya setrategi yang dominan diterapkan oleh para tokoh penyebar Islam di beberapa daerah pedalaman Jawa adalah melalui pendidikan dengan lembaga-lembaga seperti pesantren dan organisasi-organisasi tarekat yang rnerupakan aktualisasi dari ajaran-ajaran tasawwuf. Meskipun demikian, telah berlangsung suatu proses sinkretisasi yang menitik beratkan pada aspek kognitif dan aspek perilaku rnasyarakat jawa, sebagai akibat adanya dua budaya (pra-Islam dan Islam) yang sating bersentuhan, kemudian diolah sedemikian rupa sehinga tidak terjadi adanya pertentangan atau konflik. Dan pada akhirnya Islam dapat diterima oleh sebagian besar masyarakat Jawa.
Bahaya Disintegrasi Bangsa Akibat Otonomi Daerah Pada Masa Mataram Islam
Authors: Widodo Sambung
Published: April 2021

Pada masa pemerintahan Kerajaan Mataram Islam, pemerintahan raja sebenarnya merupakan hubungan yang hierarkis antara satuan-satuan kekuasaan yang berdiri sendiri, sangat otonom dan dapat mencukupi kebutuhan sendiri, yang secara vertical dihubungkan oleh ikatan-ikatan perorangan diantara beberapa pemegang kekuasaan (bupati). Selain dari ikatan-ikatan penghubung berupa pengabdian dan kesetiaan kepada satu orang yang sama, yaitu raja, nampaknya tidak ada hubungan administrative secara horizontal yang dapat memastikan atau melindungi kemerdekaan para bupati dari satu sama lainnya. Dalam kenyataannya tindakan sewenang-wenang terhadap sesama pejabat raja mudah terjadi bila daya pengawasan pemerintah pusat menjadi lemah. Keadaan yang demikian menggoda para pejabat raja (para bupati) untuk bertindak sewenang-wenang terhadap sesamanya, sebab otonomi yang diberikan kepada para pejabat (bupati) itu disertai dengan hak untuk memiliki Angkatan bersenjata sendiri.

Published: April 2021

This study examines the need/importance for ground validation of Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) observation at 2 gas flaring sites in Rivers State of Niger Delta, Nigeria. 12 Landsat imageries (3 Landsat 5 TM and 9 Landsat 7 ETM+) acquired from 25/03/1987 to 08/03/2013 with < 5 % cloud contamination were used. Both sites are located within a single Landsat scene (Path 188, Row 057). Fieldwork measurements and observations at both sites took place from (04/08/2012-21/09/2012) and (05/08/2019-22/09/2019). The parameters measured are coordinates of points and features, air temperature and relative humidity; and photographs of locations and features were taken. Both air temperature and relative humidity were measured at 3 different levels above the ground surface at 1 minute interval. The closer the distance to the flare stack, the higher the air temperature measured and vice versa. Land Surface Temperature (LST) retrieved from Landsat 5 TM and Landsat 7 ETM+ also shows that the closer the distance to the flare stack, the higher the LST and vice versa. The locational error of points obtained from Landsat 5 TM and Landsat 7 ETM+, and fieldwork measurements give negligible difference of 1.0 × 10-6 to 7.3 × 10-6. Several features, and 4 land use and land cover (LULC) within the sites were clarified. The pattern of plumes from the flare stacks moves outwardly at both sites. Results show that the spatial variability in ground air temperature and derived LST from Landsat 5 TM and Landsat 7 ETM+ differs within 0.8 to 6.0 K because air temperature is different from LST. The results of locational error, LULC, air temperature, LST, and the pattern of plumes observed at both sites show that ground validation through measurement of in-situ data is indispensable to the use of Landsat 5 TM and Landsat 7 ETM+ data and remote sensing technology in the Niger Delta.

The isotopic dating of U-Pb by the zircon method of volcanic acid zircons of the Konachan complex (Algansky mountains, northwestern part of the Koryak highlands) confirmed their Late Eocene age (34.6 ± 0.5-38.8 ± 0.4 Ma, Priabon). It has been shown that silicic rocks are represented by moderately potassium, peraluminous (ASI = 1.23–1.30), moderately and high magnesian differences, often with a high content of Cr and Ni. The contents of Sr, Y and Yb are adakite. High ratios of 143Nd/144Nd and low 87Sr/86Sr in the rocks of the complex, the distribution pattern of rare and rare-earth elements suggest that the source of salite melt, to some extent contaminated by sedimentary material, was metabasites. The formation of the Konachan complex is caused by magmatism during accretion of terranes of the Olyutor-East Kamchatka island-arc system [27]; compression processes led to the blocking of the upwelling front of the continental asthenosphere, initiating intense crustal anatexis and silicate magmatism.

The results of the biostratigraphic study based on the radiolarian analysis of the rhythmically layered terrigenous deposits from the Islands of the Rimsky-Korsakov Archipelago (Peter the Great Bay, Japan Sea) have been presented. These deposits are most similar to the medium-grained turbidites. For the first time the distribution and stratigraphic division of the boundary sediments of the upper Triassic and lower Jurassic separated by a marking layer were substantiated in the research area. On the basis of comparisons with isochronous zonal units of the Pacific and Tethyan areas in the upper Triassic sediments of the studied sections, layers with Globolaxtorum tozeri (upper Rhaetian) were established, and in the lower Jurassic zone Pantanellium tanuense Zone (Hettangian) was traced and layers with Parahsuum simplum (Sinemurian – Pliensbachian) were established.

Published: April 2021

Rhythmic gymnastics (RG) is a competitive sport and competition results include multiple components such as difficulty (D) and execution (E) scores. Both coaches and researchers should consider the components of performance scores separately. The aim of the current study was to identify the most indicative apparatus score on total ranking in the individual all-around finals of 37th RG World Championships (WCh), 2019, Baku, Azerbaijan and to determine the most important D and/or E scores on overall ranking. Total of 312 scores of 24 gymnasts competed at individual all-around finals were analyzed. Correlations among total qualification, total D, total E, and total apparatus scores of each apparatus were determined by Pearson correlation analysis. Multiple regression analysis was used and model-fitting performance was assessed by coefficient of determination (R2). When correlations among total qualification score and total D, total E scores of each apparatus were analyzed moderate and strong relationships were found (p < 0.001). The percentages that D and E scores explained the total score ranged between 79.3 and 44%. Total ball D score explained 79.3% of the variability in standings and it was the best predictor score. Total ribbon E score was found to be the second effective score on ranking (71%). Finally, total hoop E score had the least effect by 44%. Apart from these, two different total score estimation models that trainers/gymnasts may use practically were enhanced during this study.

En 1950, Rubén Vargas Ugarte publica las obras de don Lorenzo de las Llamosas (1655-17...) (1), cuyo texto más importante lo constituye el poema Demofonte y Filis. Relata éste cómoDemofonte, hijo de Teseo, luego de haber contribuido a la destrucción de Troya, retoma a Atenas. La escuadra del príncipe victorioso naufraga y se refugia en Tracia. Demofonte es socorrido porFilis quien, habiendo muerto sus padres —Licurgo y Cristumena— gobierna en la región. Ligados amorosamente, los dos jóvenes vivenjuntos hasta que Demofonte se ve obligado a partir hacia Atenas, prometiendo un pronto retorno. Filis, desesperada por los celos ante la creciente demora del amante, cuya traición supone, se suicida. Alrededor de esta trama se agrupan diversos episodios secundarios: percances amorosos entre acompañantes de Demofonte y su consorte; escenas de cacería; luchas, etc.

The mean age was (52.65 ± 14.80) years, proportion of female and male subjects was equal. All patients received basic drug therapy according to the Order of MoH of Ukraine. The disease duration was 10 to 30 years, the remission stage was established in all patients. Patients were randomized into two groups: main (400 people) and control (50 people) with the same COPD severity distribution. Patients of the main group received additional 30 minutes sessions of interval normobaric hypoxytherapy for 20 days. The examination were performed for the dynamics of clinical symptoms, respiratory function, nonspecific resistance of an organism.

Results. Most patients had symptoms of the disease against the background of basic COPD medication even on the remission stage. Unfavorable and intense adaptive reactions were determined in 71.33 % of COPD patients, and eustress reactions only in 16.89 %. Sanogenetic types of adaptive reactions were found in 28.45 % of subjects, maladaptive types — in 21.78 % of persons, pathogenetic — in 63.33 % of patients. At GOLD 2, tense reactions were diagnosed in 69.6 % of subjects, and in GOLD 3 in 73.0 %. As the severity of the disease increased, there was an increase in the development of intense training and activation responses. Upon completion of the course of hypoxytherapy, the exercise tolerance increased, and shortness of breath appeared only after severe physical activity in 90.25 % of patients in the main group, whereas in the control group similar changes were observed only in 20.0 % of patients. The respiratory function indicators in patients of the main group increased on average by 17.52 %, while in the control group — by 3.3 %.

In the main group, favorable adaptation reactions prevailed in 88.25 % of patients, while in the control group this indicator was 32.0 %. The percentage of adverse reactions in the main group decreased significantly and was 11.75 % after treatment, the proportion of stress reactions — 46.25 %. In GOLD 2, the proportion of pathogenetic reactions decreased to 17.33 % and 56.00 % of the main and control groups, and in GOLD 3 — in 20.44 % and 44.0 %, respectively (p < 0.05).

Conclusions. The use of a course of normobaric hypoxytherapy promoted the reduction of the main clinical COPD symptoms, increase of the frequency of favorable adaptive reactions up to 88.25 %, it raised clinical effectiveness of the treatment, which allowed to avoid disease exacerbations during the year in 80.95 % of patients.

This study investigates determinants of socio-environmental practices, (mandatory and voluntary), as evidenced in southern Brazil’s electric energy distribution companies. It seeks to understand this phenomenon with interdisciplinary protection through theoretical constructs of Social Responsibility, Environmental Management, Evidence, Legitimacy, Reputation, and Institutional. This integration contributes to understanding the reasons why companies undertake and evidence their socio- -environmental practices to external audiences. The literature suggests that socio-environmental practices are explained by various reasons, such as: enforced by legal impositions and/or voluntariness, to strengthen legitimacy, maintain and develop a reputation, and by isomorphism of the competitive operating environment. Given the above, the objective of this work is to investigate factors that determine the disclosure of socio-environmental practices in electricity distribution companies in the south of Brazil. In the methodological aspects, a qualitative approach was used, with descriptive and exploratory objectives. As a research strategy, a multichannel study was applied through two electricity distribution companies in the south of the country, CELESC Distribuição S.A. (Centrais Elétricas de Santa Catarina) and COPEL Distribuição S.A. (Companhia Paranaense de Energia). Data collection took place in two stages, the first one with a search on documentary, physical and virtual basis, and the second stage using a semi-structured interview with professionals from the Social and Environmental Responsibility area of each of the companies surveyed. The information collected was related to the period of 2014, 2015, and 2016. The results showed that the Annual Reports, service stations, and participation in external events constitute the primary means and channels of evidence of socio-environmental practices. There was a greater tendency to develop social practices. However, there are programs focused on climate change, conscious consumption and electricity saving, social inclusion, recovery of citizenship, and people’s quality of life. The COPEL company presented a tendency to evidence voluntary practices with more intensity, also showing consistency and maintenance of the programs during the studied period. Regarding corporate and sustainability policies, it was noted that companies adopt very similar strategies. It is concluded that the age, size, and corporate reputation of companies are the main determinants of socio-environmental practices, highlighting the presence of mimetic isomorphism characterized by the use of the same types of means and channels of evidence and by the symmetry of practices and policies developed by companies CELESC and COPEL.
Historical and textual research and essence analysis of the evolution of Lenin’s “German Spy” case
Authors: Yan Li
Published: April 2021

The rumors that Lenin was a “German spy” first appeared in Petrograd after the February revolution in Russia. During the Soviet period, the “Sisson documents” (papers) were fabricated in the United States and other Western countries, and other evidence was sought that Lenin was allegedly an “agent” of the German government. However, all the evidence presented were convincingly refuted. V. I. Lenin’s “German spy” case was discussed again during the collapse of the Soviet Union and in post-Soviet Russia. In some Russian media, political and academic circles, this “case” was reproduced in various forms, but new materials and new evidences were not found.
МУТАГЕННА ДЕПРЕСІЯ ПШЕНИЦІ ОЗИМОЇ (TRITICUM AESTIVUM L.) ПРИ ДІЇ ГАММА-ПРОМЕНІВ
Authors: Назаренко М. М.
Published: April 2021

Метою наших досліджень було виявити особливості депресивних наслідків післядії різних доз гамма-променів у сортів пшениці озимої місцевої селекції за показниками схожості, виживання, морфометрії, врожайності. Досліджено показники схожості та виживання, проходження основних фаз онтогенезу в рослин пшениці озимої сортів місцевої селекції (Комерційна та Співанка) у першому поколінні. Встановлено вплив мутагенної депресії на показники структури врожайності (морфометрію стиглих рослин) та встановити рівень їх мінливості. 2019–2020 рр. експерименти проводили на дослідних полях науково-дослідного центру Дніпровського державного аграрно-економічного університету. У дослідах використовували насіння сортів Співанка та Комерційна, опромінене гамма-променями в дозах 100, 150, 200, 250, 300 Гр. Контроль – сухе насіння. Встановле-но, що вища депресія за всіма дослідженими ознаками проявилась у сорту Співанка, крім дози 250 Гр, що свідчить про специфічність взаємодії депресійної активності гамма-променів із геноти-пами окремих сортів та складний характер розвитку депресивних наслідків на рівні організму. Най-більш інформативними показниками щодо мутагенної депресії в М1 поколінні рослин сортів пшениці озимої м’якої були: схожість та виживання рослин, фертильність пилку та такі показники струк-тури врожайності, як висота рослин, вага зерна з головного колосу, маса тисячі зерен. Усі ці показ-ники з високим рівнем значущості пов’язані з показником доза мутагену. Генотипи сортів місцевої селекції (Комерційна та Співанка) виявилися високочутливими до дії гамма-променів, що проявилось у напівлетальності навіть початкових, помірних доз (100 Гр). Дисперсійний аналіз показав, що насамперед на формування показників структури врожайності впливав фактор «доза мутагену», потім генотип вихідного сорту. Виявлено, що може відбуватися стрімке зниження окремих пара-метрів у першому поколінні при досягненні окремих граничних доз, причому ці дози визначаються генотипом суб’єкта мутагенної дії.
ПРОДУКТИВНІСТЬ ПОЛЬОВОЇ СІВОЗМІНИ У РАЗІ КАЛІЙДЕФІЦИТНОЇ СИСТЕМИ УДОБРЕННЯ

Висвітлено результати досліджень впливу тривалого (8 років) застосування калійдефіцитної системи удобрення в умовах Правобережного Лісостепу України на зміну параметрів фізико-хімічних і агрохімічних показників чорнозему опідзоленого важкосуглинкового та продуктивність польової сі-возміни (пшениця озима, кукурудза, ячмінь ярий, соя). Встановлено, що використання чорнозему опідзоленого для вирощування польових культур за різних умов удобрення не змінює ємності ґрунто-вого вбирного комплексу, але спричиняє його структурну перебудову. Перед закладанням досліду єм-ність ҐВК у шарі 0–20 см на 10,1 % визначалася іонами водню, а через вісім років у разі середньоріч-ного внесення N110P60K80 їх частка підвищилась до 14,8 %. Калійний режим ґрунту залежав від видів і доз добрив, що застосовувалися в сівозміні. Найбільше на нього впливали дози калійних добрив. Так, на ділянках без добрив у кінці другої ротації 4-пільної сівозміни вмісту рухомих сполук калію у ґрунті зменшився порівняно з вихідним значенням на 6 %, а у разі внесення N110P60, N110P40 і N110P60K80 на 1 га площі сівозміни – відповідно на 14; 5 і 3 %. Тривале (з 2010 р.) застосування мінеральних добрив у дозі N110P60K80 на 1 га площі сівозміни в середньому за 2016–2018 рр. сприяло підвищенню врожайності пшениці озимої на 3,68 т/га, кукурудзи – на 8,34, ячменю ярого – на 2,05 і сої на 1,31 т/га, врожай-ність на контролі без добрив відповідно 3,57 т/га; 4,73; 3,37 і 1,71 т/га. При цьому калійні добрива на азотно-фосфорному тлі в дозі 40 кг/га д. р. сприяли підвищенню врожайності пшениці озимої, кукурудзи, ячменю ярого та сої відповідно на 7; 12; 5 і 3 %, а продуктивність сівозміни підвищилася на 8 %. Подальше підвищення дози калійних добрив до 80 кг/га д. р. підвищувало її продуктивність лише на 4 %. Для забезпечення продуктивності польової сівозміни на рівні 7,55 т з. од/га необхідно що-річно на 1 га площі сівозміни вносити калійні добрива в дозі 40 кг/га д. р. (під пшеницю озиму 40, куку-рудзу – 55, ячмінь ярий – 35 і сою – 30) на тлі N110P60 і заробляння у ґрунт нетоварної частини урожаю.
