Published: December 2022

The article describes the role of epicuticular wax in terms of its morphology and physiology as one of the resistance mechanisms of plants of the Brassicaceae family to various biotic and abiotic stresses based on the analysis of foreign scientific literature. The review provides a detailed description of the cuticle structure and epicuticular waxes on its surface, which can be represented as very diverse composite microstructures. We analyzed their important role in the efficiency and stability of the transpiration barrier in accelerating water loss, and we found it to be universal protection for plants under moisture deficit. The wax compositions vary in their response to temperature. The amount of wax and the morphological structure of the crystalloids changes when exposed to high and low temperatures. Wax production tends to increase at lower temperatures (15 °C and below) and to decrease at temperatures above 15 °C. It has been observed that the amount of wax in the plant cuticle increased with increasing UV radiation. Wax formed on the leaves of plants of the Brassicaceae family is one of the factors affecting the damage pattern of insect pests (such as cruciferous fleas, bedbugs, etc.). It can affect insect feeding both through physical mechanisms and by affecting the digestive system. The percentage of damage decrease is 64 % depend-ing on the wax thickness on the surface of the plant. Epicuticular wax on the leaf surface is one of the mechanisms of plant protection of the Brassicaceae family against fungal and bacterial pathogens (Sclerotinia sclerotiorum, Alternaria brassicae, etc.). The morphology, placement, and thickness of the crystalloids, as well as the chemical characteristics, determine how effectively the plant can control various kinds of infections.

Castor bean (Ricinus communis L.) is a valuable high-oil technical crop, belonging to the Euphorbiaceae family. In the climatic conditions of the Rostov region, it is an annual, thermophilic plant. The castor seed kernel is the most valuable part of the plant, containing on average up to 75 % oil. Since 1926, breeding work has been carried out at the Don experimental station in the direction of develop-ing varieties suitable for cultivation in moderate climates. The main focus of breeding has been the de-velopment of highly productive, early-maturing castor bean varieties with indehiscent boxes suitable for mechanical harvesting. Castor seeds are known for their variety of sexual forms: ambisexual, male, female, as well as semi-female (female plants with a small number of male flowers) and scattered (plants with a mixed arrangement of male and female flowers). Using various methods of increasing the number of female plants, the Don experimental station has received breeding material that contributed to increasing the productivity of the crop. By the method of hybridization, mass, and individual selection, new productive varieties have been developed that fully meet the requirements of the time. Castor is a good forecrop for winter crops, due to the high content of nitrogen and potassium in the stems, when plowed they serve as a good organic fertilizer. When cultivated in crop rotation, castor increases soil fertility and protects the soil from soil pests such as wireworm, may beetle larvae, etc. Currently, castor is cultivated in many countries of the world, including Russia. The Rostov region is one of the northernmost areas of cultivation of this crop. Currently, the Don experi-mental station continues breeding work on the development of new castor varieties that combine re-sistance to stress factors, early maturity, yield, and product quality. The result of many years of work by breeders at the Don experimental station is a new high-yielding, highly productive variety of castor Udacha.
Development Of Teachers' Perception Scale Regarding of Visual Arts with NFT: Validity – Reliability Study
Authors: VURAL Ömer Faruk , BAŞARAN Mehmet
Published: December 2022

NFT technology such as the Metaverse, Virtual Reality and Extended Reality will change how educators teach and how students learn. NFT technology will also affect Lifelong Education. The study aimed to develop a scale of 25 items to measure how NFTs create a perception among teachers, providing a new understanding of art. For this purpose of the study, data were collected from 310 teachers (135 teacher samples for exploration and 175 teacher samples for confirmatory factor analysis) teaching in various cities of Turkey. The principal component analysis of the varimax rotation was used to obtain evidence for the scale’s validity. As a result of exploratory factor analyzes, three items were excluded from the survey because their item loads were coincident, and as a result, the scale was reduced to 22 items, and three sub-dimensions emerged. It has been determined that the scale has a structure composed of three factors: “NFT’s contribution to art and artists,” “NFT’s positive contribution to art,” and “NFT’s negative contribution to art.” It was observed that the item test correlation of the scale changed between 0.44-0.88. At the same time, cross-validation analysis was performed to determine whether the scale would produce the same results. When it was applied to similar groups as a result of cross-validation, it was observed that the same result could be obtained when the scale was applied to the same group. Apart from this, to give evidence in terms of the scale’s validity, the re-test and Crα reliabilities were calculated, and it was found to be 0.947.

El problema del superávit por dependencia en los planes de pensiones de empleo
Authors: de la Peña Esteban J. Iñaki , De La Peña J. Iñaki , Martín Iratxe D.
Published: December 2022

Dentro de los productos de previsión social complementaria se encuentran los planes de pensiones de empleo tanto de aportación como de prestación definida. Su finalidad es compensar al trabajador por jubilación, muerte, supervivencia o invalidez. Ni en la contratación ni a lo largo de la vida laboral se tiene en cuenta la situación de dependiente, que sí que repercute cuando el trabajador se convierte en beneficiario de una prestación. Si decide percibir una pensión periódica el capital correspondiente a la edad de jubilación se transforma en una renta vitalicia (en caso de aportación definida) o directamente comienza a percibir la renta vitalicia inicialmente determinada (prestación definida). En estos casos se calcula bajo una base técnica concreta que contempla una expectativa de mortalidad determinada. Sin embargo, hay experiencia internacional que evidencia que la mortalidad del dependiente es superior a la población general y asegurada, por lo que el dependiente, de percibir la misma pensión, la recibiría por menor plazo. El objetivo del presente trabajo es determinar el impacto económico que genera el cambio de estatus en el beneficiario cuando recibe esa renta vitalicia. Hay que subrayar que, en la renta vitalicia, el riesgo biométrico es asumido por el asegurador y que una menor esperanza de pago debido a que el beneficiario de la pensión pase al estado de dependiente conlleva un beneficio económico, pues esa ganancia no se reparte a la familia del beneficiario. Se crea un superávit al abonar la misma prestación. Así, el empleo de una adecuada asunción de mortalidad produce una reducción de la provisión matemática de pago, lo que redunda en liberar capital y tener un menor capital de solvencia requerido.

Authors: Galimulina F. F. , Shinkevich M. V. , Zaraychenko I. A.
Published: December 2022

The best available techniques (BAT) today serve as a tool to overcome the turbulence of economic processes. The purpose of the study is to substantiate the role of the best available techniques for modern Russian industry in the face of new challenges. The author’s position is based on a broad view of BAT that goes beyond environmental aspects. In this regard, a conceptual model of BAT is proposed, based on the idea of harmonizing the development goals of industrial systems against the background of sanctions pressure on the Russian economy and technological backwardness of domestic manufacturing enterprises, and convergence of key trends in industrial development, in particular, sustainable development, the ESG concept, the green economy and the closed-loop economy. A distinctive feature of the author’s approach is the expansion of the boundaries of the potential effect, taking into account its correlation with global trends in industrial development. It is proved that the BAT are able to play the role of a springboard to achieve technological sovereignty of Russia. The formulated scientific provisions can be taken into account within the framework of the development of the BAT methodology.

Authors: Zhilkin O. N. , Chavarry G. W.P.
Published: December 2022

The article analyses the historical aspects and prospects for the development of foreign trade relations between Peru and Russia. The dynamics of RussianPeruvian diplomatic relations was studied, the most significant periods of these relations were highlighted, the crisis periods that affected cooperation between countries, including the Second Pacific War (1879−1884) were identified, and the collapse of the USSR. The most fruitful period in the history of Russian-Peruvian relations is marked by the beginning of the “most-favoured-nation” regime, established in 1969 after the signing of the Trade Agreement by the parties. The key aspects of the current state of trade cooperation between Peru and Russia are highlighted. The intensification of trade cooperation in the modern period occurred after the meeting of the presidents of Russia and Peru in 2008 at the Asia-Pacific Economic Cooperation summit in Lima. The commodity structure of trade relations between Peru and Russia is considered. It is suggested that the priority tasks for the further active development of Russian-Peruvian cooperation can be considered the increase and diversification of trade, the growth of mutual investment, and the signing of a bilateral free trade agreement. The methodological basis of the research includes general scientific methods: historical-legal, structural-functional, comparative-legal, formal-legal, statistical. The information work was compiled scientific literature, monographs, regulatory documents, and reference materials that demonstrate the functioning of foreign economic activity, including between Russia and Peru.
Transfers as an effective instrument of public finance resilience
Authors: Sakhapova G. R.
Published: December 2022

The article analyses the budgetary provision of the regions in the Volga Federal District. A vertical and horizontal imbalance of budgets has been revealed. Only two regions are not subsidized, with estimated budgetary capacity above the national average. To balance the budget system and strengthen its resistance to crisis phenomena in the economy, the resilience property of public finances was considered. It has been established that one of the instruments of resilience is interbudgetary transfers, the improvement of distribution methods of which makes it possible to increase the flexibility and adaptability of the regional economy in a period of environmental turbulence. The existing models for the use of intergovernmental transfers are identified and considered: 1) the introduction of blocks for the distribution of subsidies into the system of substantiation of budgetary appropriations based on the developed methods, 2) a binary model for managing the socio-economic development of the region, which performs the dual functioning of the transfer mechanism and priorities strategic development. In order to increase the territories resilience, a model for managing the transfer mechanism is proposed, which, unlike the existing ones, provides for taking into account the stage belonging of the territories, the features and patterns characteristic of each stage of the life cycle (four stages: education, development, maturity and decline).

Published: December 2022

Nowadays, one of the important missions of higher educational institutions is the organisation and introducing students to a culture of health. The purpose of this study is to propose a strategy for the development of health-saving technologies by implementation of project activities into the educational process based on the Physical Education Department at the State University of Management for the formation of competencies in the chosen professional activity. The sociological survey was carried out among students at the State University of Management. The questionnaires included questions on students’ attitudes towards physical culture as an integral component of a healthy lifestyle. The degree of interest of the respondents in project activities in general and on the basis of the Department of Physical Education at the university, in particular, to improve the acquired professional competences was determined. The results of the study point to the need to modernise approaches to the formation of healthy lifestyle values, including the organisation of physical culture events, the development of a marketing plan to attract mass attention to the sports life of the university, where the main role is given to self-education and the realisation of the individual’s potential through active participation in university sporting life.

Published: December 2022

Today, the mainstream in the development of inclusive social initiatives is to create equal conditions for every member of society. The results of sociological studies that determine the main preferences in the field of career building and employment opportunities for young people with disabilities are presented. The main behavioural characteristics of this category of young people are described. The most useful skills acquired in the process of studying in educational institutions were the ability to listen, manage time, conflicts. These are the qualities that any person needs to effectively organise his life, establish contacts, establish interpersonal relationships. The study revealed the desire of young people with disabilities to look for work, find a job, but often the jobs provided by employers do not meet the necessary minimum requirements or the physical abilities of job seekers do not allow them to find a job. This study has made it possible to outline the range of problems faced by young people with disabilities in finding employment and choosing a career.

Authors: Zinchenko Yu. S. , Gusarenko V. V.
Published: December 2022

The article presents the results of the study aimed at identifying the level of influence of distance learning on the psychological well-being of students. The objects of the study are the environment and factors having a negative impact on the psychological well-being in the student environment of the Krasnoyarsk State Medical University named after Professor V.F. Voyno-Yasenetsky. In order to explore the main challenges of digital pedagogy, a questionnaire survey of 140 second year students of the medical, pediatric and dental faculties of the university was carried out. The results of the survey have demonstrated that distance learning had a negative impact on the rhythm of students’ classes, negatively affected the level of student responsibility in the educational process and the causes of emotional burnout. During remote classes, the conflict between students decreased, and along the line of student-teacher interaction, on the contrary, it increased. The results of the study may be of interest both to the management of universities and to the teaching staff, since the distance format is being introduced into the usual learning activities of students.

Authors: Egamberdieva E. V. , Tsvetkova N. A.
Published: December 2022

The article is based on the data of an empirical study carried out in 2022 with the participation of 148 students of the MGIMO University – Russian’s citizens, one half of whom identified themselves as Russian, and the other attributed themselves to other ethnic groups. The personal prerequisites for psychological safety, which are characteristic of Russian students who define themselves as “Russian”, include: a normative variant of the development of five basic characteristics that make up the structure of a “normal” personality; tolerance as a personality trait; average and a lower authoritarianism index relative to the other group; components of self-actualisation – support, behavioural flexibility, cognitive needs; medium-developed subjectivity; adequate level of psychological defenses. The students – Russian citizens who attributed themselves to other ethnic groups, have: a normative version of the development of the five basic characteristics of a “normal” personality; an average overall level of tolerance and authoritarianism as well as self-actualisation; an adequately high level of belief in the fairness of the world, their good fortune and ability to control events; activity as a leading component of subjectivity; a willingness to establish a social distance with other ethnic groups that facilitates dialogue. Based on the results of the survey, personal preconditions that can cause inter-ethnic conflicts have been identified.

Authors: Stroev V. V. , Tikhonov A. I.
Published: December 2022

Currently, active developments are underway to implement human and production resource management standards, new management mechanisms are emerging and being supplemented, but first of all, management activities can be assessed by the management decisions taken by the decision-maker, and the results that this management decision has brought. The relevance of the chosen topic is due to the fact that at present and in previous years there has been an increase in some independent variables, so management decisions at enterprises and other organisations are becoming more difficult and require taking into account larger criteria than usual. Therefore, the choice or development of a competent methodology for the management decision-making process would help the decision-maker not only to choose the most effective management decision, but also to minimise possible financial, social and other risks. The groups of factors that have a significant impact on the process of developing management solutions have been identified. The authors propose a step-by-step methodology for assessing the effectiveness level of the management decision-making and implementation mechanism. An updated version of the structural content of the methodological components necessary for the development of management solutions is proposed.

Comparison of the efficiency of zero and first order minimization methods in neural networks
Authors: Gubareva E. A. , Khashin S. I. , Shemyakova E. S.
Published: December 2022

To minimize the objective function in neural networks, first-order methods are usually used, which involve the repeated calculation of the gradient. The number of variables in modern neural networks can be many thousands and even millions. Numerous experiments show that the analytical calculation time of an N variable function’s gradient is approximately N/5 times longer than the calculation time of the function itself. The article considers the possibility of using zero-order methods to minimize the function. In particular, a new zero-order method for function minimization, descent over two-dimensional spaces, is proposed. The convergence rates of three different methods are compared: standard gradient descent with automatic step selection, coordinate descent with step selection for each coordinate, and descent over two-dimensional subspaces. It has been shown that the efficiency of properly organized zero-order methods in the considered problems of training neural networks is not lower than the gradient ones.

Published: December 2022

The article examines the impact of scientific and technological progress and changes in politics and economics on management in organisation. The effectiveness of contemporary governance systems can be assessed using well-known criteria: average gain; a cautious observer (Wald’s criterion); Laplace criterion; maximax et al. The use of the VUCA-world philosophy has predetermined the search for a solution to the problem of developing new requirements for the knowledge and skills of managers and specialists in the organisation, the availability and formation of competences. In line with the aim of the work – to find new approaches and requirements for management decision-making and organisation management – new requirements for assessing the changing environment, the business response to these changes, and new aspects of managerial and personnel behaviour in organisations have been identified. It has been revealed that in business training it is necessary to pay more attention to the formation of the desire for self-improvement and the development of the ability to overcome difficult situations, to divide goals into subgoals, tasks into stages. The methods of analysis and synthesis, induction and deduction have been used. Applying the results of the study in practice will improve the management of contemporary organisations.
Problems of single-industry towns: world experience and Russian practice
Authors: Glebova A. G. , Zelensky V. N. , Lazareva A. S.
Published: December 2022

The process of industrialisation in Russia was accompanied by the creation of many cities, the economy of which is associated with a certain industry. At the same time, the city is completely dependent on one or more of the same type of enterprises. Such an enterprise is called a city-forming one, since it employs 30 % of all working people in the city, and their families make up half of the urban population. The dependence of the city on the enterprise that is one of the main problems, since the state of the enterprise directly affects the economy of the entire city. The activity of the enterprise determines the unemployment rate in the city, the size of the city budget and the state of engineering networks. In the case of a crisis and the shutdown of the enterprise, the economy of a single-industry city will face huge problems. The purpose of the study was to identify the problems of the Russian single-industry towns, and review foreign methods of leveling them. The object of the study were the Russian single-industry towns defined by the Russian Government Decree No. 1398-r dated on 29.07.2014 (revised on 21.01.2020) “On Approval of the List of Monoprofile Municipal Entities of the Russian Federation (Mono-Cities)”. The main research method was comparative analysis. The main problems of single-industry towns in Russia have been formulated: infrastructure provision and monoprofile economy. A comparative analysis of domestic and foreign experience in solving these problems is carried out and the directions of modernisation of Russian single-industry towns are proposed. Issues of legal support for the implementation of the proposed recommendations require further elaboration.

Potential-Energy Surfaces Sampled in Cremer–Pople Coordinates and Represented by Common Force Field Functionals for Small-cyclic Molecules
Authors: Charvati Evangelia , Sun Huai
Published: December 2022

The complex conformations of the cyclic moieties impact the physical and chemical properties of the molecules. In this work, we chose 22 molecules of four-, five-, and six-membered rings and performed a thorough conformational sampling using Cremer-Pople coordinates. We sampled hundreds or thousand of conformational structures including all well-known and many less well-known conformers for each molecule. We tried to represent the potential energy surfaces (PESs) by fitting the data to common analytical force field functional forms. Although the general features of PESs can be described by the essential force field functional forms, the accuracy of representation can be improved remarkably by including the torsion-bond and torsion-angle coupling terms. The best fit yields R-squared (R2) values close to 1.0 and mean absolute errors (MAEs) in energy less than 0.3 kcal/mol.
Adaptation of Chiral GC into existing undergraduate labs to improve student appreciation of stereochemistry
Authors: Griffin Nicholas , Ritchie Marshall , Lynn Tyler , Dear Kate , Deutsch Tyler , Dillard Leigha , Otoo Barnabas
Published: December 2022

The critical role of stereochemistry in life, medicine, and industry mandates that stereochemistry is well represented in undergraduate lab curricula. This has primarily been achieved via experiments in the enantiomeric resolution of asymmetric acids and bases followed by polarimetric analysis, NMR analysis using chiral shift reagents, and NMR, GC, and HPLC analysis of diastereomeric derivatives of the chiral molecules. Despite the increasing prevalence of the utility of GCs and LCs fitted with chiral columns in academia and the chemical industry, they have seen limited involvement in undergraduate training. To achieve the stereochemical laboratory requirements without sacrificing existing lab techniques, we have modified two standard laboratory experiments to include chiral GC analysis as follows: (1) The extraction of carvone from spearmint leaves and caraway seeds via steam distillation or other extraction methods is a lab widely used to demonstrate stereochemistry. However, the analysis of the products from the extraction is often limited to thin-layer chromatograms that confirm the presence of carvone and shows that the enantiomers have similar polarity. By including a GC method using a β-DEX™ 225 column in this lab, students were able to compare retention times of the spearmint and caraway extracts with those in a racemic mixture, then predict whether they are R or S by comparing with an injection of a pure R-carvone sample. (2) The reduction of aldehydes and ketones is another common experiment done in most institutions. Sodium borohydride reduction of acetophenone produced a racemic mixture which was observed as two retention times on the chromatogram. Reduction using the two enantiomers of commercially available CBS catalysts provided relatively enantiopure alcohols. Students could predict which enantiomers resulted from each enantiomer of the CBS catalyst by comparing it with a commercially obtained enantiopure alcohol. They also used chromatographic data to calculate the enantiomeric excess from their reactions. The experiments also teach students other essential techniques like inert-atmosphere techniques, thin-layer chromatography, the use of multivendor software for analysis, and the effect of reaction conditions on product yield and stereochemistry

This study developed two to six multivariate regression equations that reliably predict global radiation in Jos (Latitude 9.87 °𝑁 and Longitude 8.75 °𝐸). Thirty-one years (1980 – 2010) observed monthly mean daily global solar radiation, sunshine hours, maximum and minimum temperatures, cloud cover, rainfall, relative humidity and wind speed data were used in this study with the clearness index as the response variable and other variables as predictors. The seven validation indices employed are the coefficient of determination (R2), Mean Bias Error (MBE), Root Mean Square Error (RMSE), Mean Percentage Error (MPE), t – test, Nash – Sutcliffe Equation (NSE) and Index of Agreement (IA) to determine the reliability, suitability and applicability of the developed models. The results in this study revealed that all the developed multivariate models were found reliable for global solar radiation estimation in Jos depending on the obtainable meteorological data measured in the location. The correlation between the measured and predicted (developed) global solar radiation shows a perfect correlation as depicted from the figures.

Published: December 2022

In this study, linear Volterra-Fredholm integral equations are approximatively solved in terms of Lucas polynomials about any point in this study using a practical matrix approach. This technique uses collocation points and Lucas polynomials to transform the aforementioned linear Volterra-Fredholm integral problem into a matrix equation. Lucas coefficients are unknown in the system of linear algebraic equations. With the use of an error estimation, some illustrated examples are also provided. The outcomes demonstrate how effective and practical the suggested methodology is. Code was created in MATLAB to acquire the matrix equations and answers for the chosen issues.

It has been shown that Ranked Set Sampling (RSS) is highly beneficial to the estimation based on Simple Random Sampling (SRS). There has been considerable development and many modifications were done to this method. The problem of estimating the population means is an integral aspect of a scientific survey. The estimators were examined for cum-dual products under Ranked Set Sampling (RSS), while the first-order approximation to the bias and Mean Square Error (MSE) of the proposed estimators were obtained. The numerical illustration of the comparisons was carried out to support the claim that the proposed estimators are more efficient than some existing estimators. Data were simulated for study variable y and auxiliary variable x using R software for the analysis to support the claim. The result shows that MSE of the proposed estimators, y ̅_(pd,RSS)^* is smaller than the MSE of the existing estimators y ̅_pd^*,y ̅_Rd^*, y ̅_(R,RSS)^*,y ̅_(RSS,MM1)^* and y ̅_(RSS,MM2)^* and y ̅_(RSS,MM3)^* at ρ = −0.1,−0.2,0.1,0.2, hence, the proposed estimator performed better than the existing estimators. While the MSE of the proposed estimator yy ̅_(pd,RSS)^* is greater than the MSE of the existing estimators y ̅_pd^* and y ̅_Rd^* at ρ = -0.3 and 0.3. However, the proposed estimator y ̅_(pd,RSS)^* does not perform better than the estimators, y ̅_pd^*,and y ̅_Rd^* at ρ = -0.3 and 0.3. It was concluded that the proposed estimator was more efficient than a class of regression estimators and four existing ratio-type estimators based on RSS.

MODELING THE VOLATILITY FOR SOME SELECTED BEVERAGES STOCK RETURNS IN NIGERIA (2012-2021): A GARCH MODEL APPROACH
Authors: Mohammed Tanimu , Umar Yahaya Haruna , Adams Samuel Olorunfemi
Published: December 2022

The volatility of equity returns for two beverages traded on the Nigerian stock exchange is the subject of this study. The ARCH effect test demonstrated that the two beverages disprove the claim that there is no ARCH effect. According to the preliminary analysis, both beverages were volatile. CGARCH and EGARCH were chosen as the best volatility models for Guinness Nigeria Plc returns and Nigeria Breweries returns, respectively, based on model selection criteria. The EGARCH model, on the other hand, rejected the idea that Guinness Nigeria Plc’s equity returns respond equally to negative and positive shocks of similar magnitude. This study’s findings suggest that the government should be cautious about how it manages inflation and foreign direct investment because they affect the rising stock price. Financial stability will likely be a more direct and explicit part of the macroeconomic responsibilities of central banks in the coming years.
CLOUD COMPUTING’S USE OF CRYPTOGRAPHY
Authors: De Rajesh , Nanda Ipseeta , Kumari Varsha
Published: December 2022

Cloud computing is a platform for dynamically enhancing capabilities and increasing potentialities without requiring the addition of new hardware, employees, or software. Additionally, cloud computing began as a business notion and later became a successful IT innovation. Concerns have been expressed about the security of the cloud environment, though, considering that the cloud contains a lot of information about people and businesses. Although cloud computing has received a lot of attention, clients are still hesitant to move their businesses there. However, the only significant issue preventing greater adoption of cloud computing is a lack of protection. Additionally, the market is wary about cloud computing due to the intricacy with which it controls data protection and confidentiality. When used in a cloud context, the cloud model architecture jeopardises the security of current technology. Therefore, cloud service customers should be aware of the risks associated with uploading data into this novel environment. Therefore, several areas of cryptography that endanger cloud computing are examined in this work. This paper provides an overview of the specific security concerns that using cryptography in a cloud computing system raises.
STUDY OF ELECTROMAGNETIC RADIATION ON FLOWER
Authors: De Rajesh , Nanda Ipseeta
Published: December 2022

Electromagnetic Radiation comes out from different electrical, or electronics gadget used for Lab as well as household purposes. As many circuits of household, industrial, and communication systems operate at close proximity of each other and one such circuit can affect the performance of other nearby circuits adversely via inadvertent couplings of their signal through near and far region, propagating electromagnetic fields. Electromagnetic waves generated by different wireless systems like mobile systems, satellite systems, other microwave links, etc. facilitates our communications throughout the world. Thus the hazard of electromagnetic radiation causes interference among these instruments and at the same time affects the living cells which includes both plant and animal cells. Here our research is to study the electromagnetic radiation of all these instruments including mobile phones on the plant cells. For the purpose of this study, here Hibiscus Flower is taken, exposed to electromagnetic radiation for the different time interval with a constant power and at certain temperature. It is observed that the physical condition of the flower as well as dielectric constants is changed. Here, in this case the dielectric properties have been measured on a flower named Hibiscus (petals) using open ended coaxial probe technique at four different temperature levels i.e. at 0th hour, after 1hour, after 2hours and after 3 hours. There are the dielectrics properties for mentioned flowers have been measured and plotted graphically within frequency range of 0.02 GHz to 8.5 GHz at many sample points. Another important observation is that the condition of Hibiscus petals at different time interval after exposing electronic magnetic radiation from Horn Antenna. From this study we can get an idea that how electromagnetic radiation can be affected for plants.
