Published: December 2021

The article considers the institutionalization of land relations and the imperatives of efficient use of land and resource potential of agricultural enterprises of Ukraine. Within the institutionalization of land relations, the methodical approach to complex estimation of effective use of land and resource potential of agricultural enterprises is substantiated, by definition of an integral indicator of efficiency (quantitative and qualitative characteristics of involved resources, productivity and efficiency) of basic kinds of activity of economic entities on agricultural lands. Indicators of transparency in the assessment of land and resource potential and indicators of land policy according to the level of their use in agriculture are proposed. Comprehensive criteria for assessing the components of the efficiency of the use of land and resource potential of agricultural enterprises are presented. The amount of rent for land shares and the amount of fertilizer application per 1 ha of sown area of agricultural enterprises of Ukraine are analyzed. The productive capacity of natural and potential yields for grain and legumes (excluding corn for grain) in Ukraine has been determined. The normative monetary value of 1 ha of arable land in rural areas is calculated on average for one region of Ukraine, adjusted for the natural yield of cereals and legumes, without taking into account the application of fertilizers. The forecast level of technical, social and economic efficiency of the use of land and resource potential of agricultural enterprises is presented

This paper presents possible methodical approach to assessing level of the state energy security and its influence on the national security. In order to ensure proper level of the national security of the state, it is necessary to assess dangers in a great variety of areas, particularly, in the energy sector. Authors of this paper propose a version of solving the problem with the help of application of the state-of-the-art information technologies on the basis of the intellectual analysis of statistical data. The authors provide general description of the methodical approach in order to assess dangers for the existing level of the energy security. This approach is based on the comprehensive application of the grouped expert estimates, as well as on the theory of the experiment planning (the experimental design theory) and on the group method of data handling. The proposed approach is characterised by its relative simplicity and usability from the point of view of application of the already existing software products. The results, which would be obtained with the help of this method, can be easily interpreted and analysed. In addition, this paper proposes more adequate approach to understanding level of the energy security, as well the level of the national security of the state. The paper presents the specific example for assessing level of the energy security as well as procedure for finding explicit form of the computational functional with the help of the software GMDH Shell, which makes it possible to increase validity of the derived data as compared with the known approaches. Subsequent investigations will be carried out with the purpose of development of the scientifically substantiated approach to identification of the relevant criterial values of the danger indicators in order to ensure making adequate decisions in respect of responding to these dangers

Published: December 2021

Correlation analysis constitutes an essential method of statistical processing of the obtained scientific research results. Its proper application using special computer software and reliable results allow practically facilitating the work of the veterinary and livestock service in the production of environmentally safe high-quality cow's milk. The purpose of this study is to analyse the correlation between the content of toxic metals Cd and Pb in the blood and milk of cows using the STATISTICA computer software version 10.0. Scientific and economic experiments were conducted on dairy cows with different types of feeding. All animals selected according to the analogue method in terms of live weight and productivity were divided into three groups: the first control group and the second and third experimental groups. The diet included feeds with an excess of heavy metals, especially cadmium and lead. The high biological activity of pollutants affected their migration from the feed of the diet through the gastrointestinal tract to milk. To reduce intoxication of the animal body, premix “MP-A” was introduced into the main diet of cows of the second and third experimental groups, and in the third experimental group – premix “MP-” and injection of the biological product “BP-9”. First, using the Shapiro-Wilk's W test, the study verified the obtained data from laboratory tests of blood and milk for the concentration of toxic metals, the law of “normal” (Gaussian) distribution, and then the necessary Spearman's non-parametric rank correlation coefficient was selected for calculation. The analysis revealed a high correlation between the variables, which was within r=0.82-0.91 (Cd) and r=0.78-0.96 (Pb) with probability (p<0.05) in animals with different types of feeding. The discovered high correlation allows veterinary medicine specialists to quickly apply measures to reduce the toxic load of the body with elements only by analysing blood for cadmium and lead, and timely prevent the production of low-quality dairy raw materials, including using premix and phytobiopreparation tested in the experiment. Further research is aimed at analysing the correlation between other indicators of the quality and environmental safety of milk and feed, constructing regression equations that will practically contribute to the activities of specialists whose task is to ensure the production of high-quality environmentally safe cow's milk

Published: December 2021

The main objective of our experiment was to prove the effect of mesenchymal stem cells of bone marrow (MSCs) on the stimulation of liver regeneration. The attention has been paid to adaptation of stem cells to the new environment and their transfer to anatomical structures. The experiment included 40 male Sprague Dawley (SD) rats aged 10 to 12 weeks. Biomodels were divided into five groups in the same number (n=8). Group 1 consisted of a control sample of eight healthy rats. Group 2 consisted of eight rats after liver resection without application of MSCs. Group 3 was after liver resection and application of MSCs. Group 4 after liver injury induce with Thioacetamide (TAA), without transplantation of MSCs. Group 5 was after chemical damage to the liver by TAA administration and MSCs transplantation. The process of stimulation of the liver was observed based on the laboratory values of alanine aminotransferase (ALT), albumin and bilirubin. The weight of the rats in each group was also compared. Animals were sacrificed after 1 day, 7 days, 14 days, and 21 days. In our experiment we found a statistically significant decrease in ALT (P≤0.001) and bilirubin (P≤0.001) was observed in the groups 3 and 5 (treated with MSCs) compared to the groups without MSCs (Groups 2 and 4). The increase in the albumin levels in the groups 3 and 5 was statistically significant. The results of our experiment led us to the conclusion, the transplantation of MSCs has important effect for the treatment and stimulation of liver regeneration following injury. MSCs administration may be extremely useful in a number of clinical applications in the treatment of liver tumors. It will allow us to perform extensive resection of the liver without risk of liver failure

Published: December 2021

The basis of the pathogenesis of male infertility is the processes of peroxide oxidation of biological substrates, especially lipids and proteins. By destroying the sperm membrane, toxic peroxidation products reduce its motility and ability to fertilize the egg, which is determined by a decrease in the number of motile sperm in the ejaculate. These changes lead to complete or partial male infertility. The authors of the review found that is accompanied by a damaging effect on the structural and functional activity of the gonads and is manifested, in particular, by an imbalance in the hormonal background of the male body. Similar effects are characteristic of an increase in the content of reactive Nitrogen species and its metabolites, which cause nitrosative stress, which is also the cause of male hypofertility and is inseparable from the state of oxidative stress. In scientific work it is determined that the accumulation of harmful peroxidation products leads to damage and destruction of sperm DNA, reduced activity of acrosomal enzymes and mitochondrial potential of sperm, reduced overall antioxidant activity. This makes it impossible for an adequate response of the body. Multi component antioxidant defense system resists stress. It is represented by enzymatic and non-enzymatic links, which can neutralize harmful radicals and peroxidation products. It contributes to the full manifestation of reproductive function. The presence of powerful antioxidant properties of catalase, superoxide dismutase, and enzymes of the thiol-disulfide system, which form the enzymatic system of antioxidant protection, as well as selenium, zinc, copper, other trace elements, retinol, tocopherol, ascorbic acid, and vitamins as parts of the non-enzymatic system is shown. The efficiency of registration is substantiated thin biochemical shift detectors or complex methods, such as total antioxidant status of sperm or sperm plasma, mitochondrial membrane potential, etc along with simple markers of oxidative stress, such as diene conjugates, malonic dialdehyde, and metabolites of the Nitrogen Oxide cycle. Given the leading role of oxidative stress in the development of male hypofertility, the prospect of further research is the search for modern means for correction, especially among substances with pronounced redox activity

The article considers the influence of agroecological indicators on the sustainable development of the rural united territorial communities of the Western Polissya region (Ukraine) based on the current state analysis of crop production. To study the state of crop production and determine its role in the development of rural areas of the Western Polissya region, the authors used their field research, as well as data from the Main Departments of Statistics in Rivne and Volyn regions, the State Statistics Service of Ukraine, statistical collection “Crop Production of Ukraine” (2018). The following methods were applied throughout the research process: system analysis, comparison, graphical and statistical methods. The development of crop production was assessed taking into account the dynamics of the following indicators: sown areas of crops (thousand hectares), production volume (gross harvest) of crops (thousand centners), crop yields (thousand hectares-1), sown areas of crops in enterprises and households on the territory of the Western Polissya region in terms of Rivne and Volyn regions for the period from 1995 to 2019. During the study period, changes in the ratio of areas between different crops were discovered: a decrease in the sown area of sugar beet, fruit and berry crops, cereals and legumes, and an increase in sunflower, vegetable crops, etc. An increase in crop yields and a slight decrease in gross harvest were established only for sugar beet in the two regions and fruit and berry crops in the Volyn region. In the region, 51.6% of the sown area of crops is accounted for by households that supply the market with products included in the consumer basket of ordinary citizens: roots and tubers, vegetables, and melons. Enterprises are focused on growing profitable crops (technical, grain, and legumes) for export

Published: December 2021

The development of Ukrainian trade organizations in ordinary conditions is characterized by a high degree of inertia. Therefore, when situations that need to change arise, business strategies of market participants also change dramatically. Most often, such transformations are connected with external factors, such as the overall economic crisis, a sharp change in the state “rules of the game” in a particular sector of economic relations, as well as another external factor bond to the occurrence of new serious competitors. The development of organizational and economic mechanism to ensure the innovative development of retail trade, requires comprehensive consideration of internal and external factors of the studied system, the formation of strategies and programs to increase the innovation potential of its participants, their active interaction, increasing the use of innovative technologies, generating ideas and transformations. The article considers the issues related to the impact of business globalization processes on the transformation of business models of trade organizations and their operation strategy, as the degree of trade development indicates the standard of living and the state of the economy and society. The authors of the article suggest that retail organizations adapt to the changes in the macro and micro environment, using innovative components in economic and financial activities, which will ensure their competitiveness and prevent crises. The proposed model of an innovative trade organization allows to identify the goals components of innovation activities, which combine the strategic guidelines of the state regulation and help to improve the economic condition of trade organizations

Over 30 per cent Indians now live in cities. In the next 15 years, over 20 per cent more are likely to be added. Cities will thus be most impacted by the bulwarks against fury of the nature. More we remove of urban nature, the more we need these bulwarks. Green Spaces, water bodies, and trees are the bulwarks. They provide shelters to the urban poors and cool the environmental heat. Unprivileged and migrant workers do not have home of their own. They seek refuge under the trees. The trees are thus the panacea of defensive wall against vagaries of the nature. Trees cover, however, is rapidly disappearing at the cost of building cities and making way for Agriculture to expand croplands. Deforestation is a global concerns and not many countries including India are making concerted efforts to protect forest and plant more trees.

Grain discolouration is an important constraint in reducing productivity of rice. Curvularia lunata and Exserohilum rostratum are two important pathogens responsible for it. An in vitro study was undertaken to test the efficacy of different plant oils against these pathogens. It revealed from the experiment using poison food technique that all the plant oils recorded a significant inhibition over control. Among the different concentration (1, 2 and 3%) of plant oils such as Eucalyptus, Neem Pungam, Coconut and Mahua oil were tested. The result revealed that eucalyptus oil (3%) recorded the complete mycelial inhibition of C. lunata (100 %) and E. rostratum (78%) followed by pungam oil (58.8 % of C. lunata), (52% of E. rostratum) and least mycelial growth were recorded by coconut oil (3%). Our findings suggest that the plant oils may be valuable as potential antifungal properties against grain discolouration of rice.

The study examined the environmental perpetuity cost and earning yields of oil and gas marketing firms: Nigeria’s experience. Its main objective was: to specifically examine the extent to which environmental perpetuity costs influence earning yields of oil and gas marketing firms taking evidence from Nigeria. To achieve the objective, an ex-post facto design was employed and relevant data were obtained from secondary source. Multiple regression analytical tool was used to analyse the data in order to verify the hypotheses formulated for the study. The findings indicated that donations as a perpetuity cost positively influences earning yield though the influence is not a very strong one; support/social cost to destitute and less privileged significantly affect earnings per share; support to motherless babies’ homes and others significantly affect earnings per share; and donations/ social cost to nongovernmental organization significantly affect earnings per share. The researchers then recommended that government should encourage listed firms to disclose their donations which will strengthen the earning per share of these firms via increased employee productivity.

No Brasil, o mito de Electra foi de interesse de diversos dramaturgos, como no caso de Ivo Bender, ao escrever Bodas ao cair da tarde (1983). Nessa peça, a fim de atender aos moldes de um texto breve de teatro, o mito grego é “reduzido”, condensado em poucas páginas. Mas também é “ampliado”, possibilitando uma nova leitura do conhecido mito da tradição clássica. Com esse propósito, o artigo visa a analisar o mito de Electra presente em Bodas ao cair da tarde, levando em considerações as principais mudanças e inovações empreendidas por Ivo Bender no processo de reescritura.
Espaços medonhos da poesia: os elementos da poética do horror nas obras de Anne Sexton, Philip Larkin e Severo Sarduy
Authors: Kempinska Olga
Published: December 2021

Ao discutir os textos de Philip Larkin, de Anne Sexton e de Severo Sarduy, o artigo busca refletir sobre a importância da poética do espaço e das relações metonímicas para a subversão do binarismo da época estruturalista. Ao atualizar o regime das emoções negativas próprias aos contextos gótico e neogótico, e importante no âmbito vanguardista, a poesia se inscreve na resistência contra a reificação do ser humano promovida pelos discursos da opressão capitalista e de gênero. As experiências do horror do vazio e da anamorfose permitem uma reelaboração subjetiva dos dualismos especulares do narcisismo melancólico dos sistemas do poder.

Published: December 2021

Generalized Chain ratio in regression type estimator is efficient for estimating the population mean. Many authors have derived a Generalized Chain ratio in regression type estimator. However, the computation of its Mean Square Error (MSE) is cumbersome based on the fact that several iterations have to be done, hence the need for a modified generalized chain ratio in regression estimator with lower MSE. This study proposed a modified generalized chain ratio in regression estimator which is less cumbersome in its computation. Two data sets were used in this study. The first data were on tobacco production by tobacco producing countries with yield of tobacco (variable of interest), area of land and production in metric tonnes as the auxiliary variables. The second data were the number of graduating pupils (variable of interest) in Ado-Odo/Ota local government, Ogun state with the number of enrolled pupils in primaries one and five as the auxiliary variables. The mean square errors in the existing and proposed estimators for various values of alpha were derived and relative efficiency was determined. The MSE for the existing estimator of tobacco production gave six values 0.0080, 0.0079, 0.0080, 0.0082, 0.0087 and 0.0093 with 0.0079 as the minimum while the proposed estimator gave 0.0054. The MSEs for the existing estimator for the graduating pupils were 20.73, 11.08, 7.49, 9.96, 18.50 and 33.10 with 7.49 as the minimum while the proposed was 6.52. The results of this study showed that the proposed estimator gave lower MSE for the two data sets, hence it is more efficient.

Authors: OYEDEPO J.A. , ONIFADE O.S.
Published: December 2021

This paper looked at practical ways in which pasture and range management (P&RM) can benefit from application of spatial technologies; namely Satellite Remote Sensing, Global Positioning System and Geographical Information Science. Brief mention of these spatial technologies’ components and ways of their integrations (linear, interactive, hierarchical and complex models) were discussed with specific reference to P&RM. The paper also dwells on salient principles of applied remote sensing and geospatial technics in P&RM using examples and case studies revolving around rangeland management, spatial decision support and resource conservation. Specifically, the relevance of hyper spectral imageries and vegetation indices in cattle population and range roaming determination, grazing land and paddock site-specific management were demonstrated. It is hoped that the review will create awareness for the inclusion and use of remote sensing and geospatial technics in many areas of livestock management in Nigeria.
The effect of interferential current treatment duration on chronic low back pain
Authors:   , Carim Ahmed Abdul
Published: December 2021

Background to the study: Chronic low back pain (CLBP) is a common musculoskeletal complaint, which results in increased absenteeism from work and other disabilities. Interferential current (IFC) is one of the treatment modalities used by manual and physical therapists to alleviate CLBP. Interferential current involves electrical stimulation of medium frequency using two currents that cross over each other. There have been numerous mechanisms proposed on how IFC works with regard to pain inhibition; however, these remain unconfirmed. Common theories include those based on the gate control theory of pain and integrated pain theories. Although the placement of the electrodes used in the IFC application has been well defined, the optimum treatment time for CLBP has not been well researched. Therefore, this study aimed to determine what protocol regarding the duration of IFC is most appropriate in the treatment of CLBP. Aim: The aim of this study was to investigate the effect of interferential current in the treatment of chronic low back pain using variable time intervals Methodology: This study was a randomised single-blinded clinical trial which consisted of 45 participants residing in the eThekwini municipality, divided into three groups of 15 each. The participants were randomly assigned using concealed allocation to one of three treatment groups of 15 each viz. 15, 20 or 30 minutes of interferential current (IFC). Low back pain level was determined using a numerical pain rating scale (NRS-101). Pain pressure thresholds (PPT) were measured with a pain pressure algometer. The effect of low back pain on participants’ activities of daily living was assessed using the Oswestry low back questionnaire (OLBQ).The participants received three treatments over a two week period with the fourth consultation being used for the final subjective and objective measurements a week later. Results: Repeated measures ANOVA testing was used to examine the intra-group effect of time and the inter-group effect of treatment on the outcomes of NRS-101 and algometer readings. Profile plots were used to assess the direction and trends of the effects. An intra-group analysis revealed that, objectively and subjectively, all groups responded positively to treatment over time, with no significant time-group interaction. Conclusion: This study concluded that neither group is more effective than the other with respect to participants’ pain perception and the OLBQ. However, groups one and three showed the largest individual improvement between consultation one and three, compared to group two which showed consistent improvement throughout for the NRS-101 readings. Based on the results collected from this study, the shortest time frame of 15 minutes of IFC application can be used in the treatment of CLBP.

Published: December 2021

In order to investigate low back pain in an Indian and a Coloured community in South Africa, a population-based epidemiological survey was carried out in which 1 000 subjects were interviewed (500 Indians and 500 Coloureds). Subjects were selected using the Systematic Random Sampling method. A pre-tested questionnaire, designed by the researcher, was used to elicit information about the subjects' demography, general characteristics and details regarding low back pain (incidence, prevalence, severity, disability, treatment). Only subjects 18 years or older who were permanent residents of the 2 suburbs were included in the study. The author carried out the interviews personally
