Pre-Service Science Teachers’ Preparedness for Classroom Teaching: Exploring Aspects of Self-Efficacy and Pedagogical Content Knowledge for Sustainable Learning Environments
Authors: Lekhu Motshidisi Anna
Published: March 2023

The technological reconfiguration of humanity and advancement requires initial teacher training (ITE) programs that create and enhance sustainable learning environments (SLEs) where teachers are prepared to embrace posthuman pedagogy to teach confidently. This case study aims to examine pre-service science teachers’ level of preparedness and teaching efficacy beliefs to teach in SLEs. The study findings revealed that teaching science requires content knowledge and an understanding of how to teach the content. Furthermore, education programs need to be responsive to the socio-economic demands and produce 21st-century-ready graduates.  The participants’ teaching philosophy aims to promote SLEs where quality teaching will be prioritized.  Without proper training, support and resources, this aspiration will remain a mirage.  Maintaining responsive classrooms will thus be a challenge that continues to be an albatross to social change.  This study has some implications for ITE programs, impacting the school curriculum and educational transformation.
STRUCTURAL ANALYSIS AND BALANCING OF THE RECIPROCATING MOTION MECHANISM
Authors:   Kuban State Technological University, PRIKHODKO Aleksandr A. , MOVSISYAN Mger N. ,   Kuban State Technological University
Published: March 2023

The paper presents new mechanisms of reciprocating motion, built on the basis of a two-row planetary gear with non-circular gearwheels with two external gears. The desired type of the output link motion is realized by converting the rotationally reciprocating movement of the planetary mechanism output shaft using the transmission “toothed wheel — toothed rack”. The proposed mechanisms are balanced on the example of three planetary gear schemes, with one, two and three satellites. Structural analysis of gears with multiple satellites has shown that the addition of each extra satellite takes away one degree of freedom from the mechanism, as a result of which it becomes immobile. It is proposed to use a counterweight on each additional satellite instead of one two-moving kinematic pair, which leads to the elimination of redundant links. The conditions of static equilibrium for the developed schemes of planetary mechanisms are obtained, which make it possible to locate the centers of mass of the mechanisms on the axis of rotation and thereby significantly reduce noise and vibration in the gear developed on its basis.

The aim of this work is to assess the compliance of the estimated lifetime of the planetary gearbox of hydromechanical transmission of a BELAZ mining dump truck with the actual operational one based on the results of accelerated (forced) bench tests. Preliminary strength calculations were carried out for the two most stressed modes of movement of a mining dump truck in a quarry on the rise, where the most significant damage to gear trains takes place: for maximum productivity (power) and maximum torque. Investigations showed that the gears limiting the lifetime of the gearbox are the sun gear and satellites of the 3rd planetary series. As a result of the tests, the estimated operating time of the planetary gearbox on the bench was achieved, which guarantees an operational life of at least 400,000 km of the dump truck run.

As a result of a theoretical analysis of the cooling process of parts with deposited coatings applied by the method of centrifugal induction surfacing, the patterns of formation of residual stresses are established, taking into account relaxation. It is shown that a decrease in the cooling rate after surfacing makes it possible to reduce the level of residual stresses due to the relaxation phenomenon. Calculation relations are derived that allow predicting the permissible value of residual stresses depending on the required adhesive strength. As the analysis of the ratios obtained shows, the reduction of residual stresses in the resulting coatings due to their relaxation can be achieved by reducing the cooling rate or, accordingly, increasing its time. In the technological process of induction surfacing, a two-stage cooling mode of the workpiece was used; at the first stage, cooling is carried out at the maximum possible rate. If the temperature stresses reach the maximum allowable value τmax, the pairing condition for the transition from the previous cooling stage to the next one is the equality τmax = τi, where τi is determined from the equations derived in the work. In this case, one should be guided by the observance of the condition τi < τc, where τc is the theoretical adhesive strength of coatings in the absence of residual stresses. An example of the practical use of the twostage cooling after the process of applying coatings by centrifugal induction surfacing on the bushings of tamping blocks of a STS track machine is given.

The role of agriculture is an extremely important one because it provides the necessary production of foods for the population and, at the same time, represents a source of raw materials for different processing industries. For a growing population, agriculture has been the main source of agri-food products that must ensure the food security of the population. Compared to other states of Europe, Romania is one of the European countries with the most favourable soil and climate conditions for agriculture. The last world crises, from the crisis in 2008 to the pandemic crisis in 2020-2021, and especially to the current conflict between Russia and the Ukraine, have brought up the issue of food self-sufficiency. During the current period, it is important to know what production can be obtained in Romanian agriculture and if it can provide the food necessary for the population. An analysis regarding the dynamics of the cultivated areas and production of the main crops in Romania has been carried out, for each of its 8 development regions. The data, collected from different sources, were analysed using different methods. The research results highlight, for example, that Romania can easily achieve the self-sufficiency stage for most agricultural products of plant origin. In conclusion, natural resources, as well as the existence of a certain material base in Romanian agriculture, can ensure the increase of agricultural production, the satisfaction of the food needs of the population, as well as a certain availability for export.

Reactive attachment disorder (RAD) arises when a secure attachment to primary caregivers does not develop in early childhood as a result of severe experiences, neglect or deprivation, abuse, or abrupt separation from caregivers between six months and three years of age, or as a result of a lack of adequate response by the caregiver to the child’s communication needs. Objectives: To perform a literature review on the assessment, diagnosis and care of reactive attachment disorder. Conclusions: For the diagnosis of reactive attachment disorder, it is recommended to use the DSM-V and ICE-10 criteria, and not to use tools for the detection of patterns or difficulties attachment. Psychotherapeutic interventions are recommended to help children with reactive attachment disorders and their caregivers. Therapy is conducted from two different perspectives: with the caregiver alone or with the child-child pair. The use of video-feedback interventions is recommended. There is an extensive literature available in the field of attachment and attachment patterns. However, in the case of reactive attachment disorders the available evidence is very limited in terms of diagnostic tools and interventions.

The use of the method of expert assessments is an indispensable element of the search for reserves to improve the quality and safety of medical activities for the realization of strategic tasks in the field of population conservation and improvement of health indicators of the Russian population.

The purpose of the studywas to assess the factors influencing the appeal for drug treatment of alcohol–associated diseases in state medical organizations on the model of a large agro-industrial region.

Materials and methods.Anonymous sociological survey was conducted in 2022. 135 doctorsspecialist in the field of “Psychiatry-narcology” working in outpatient or inpatient units of the public health system of the Krasnodar region. The following methods were applied in this study: sociological, statistical, content analysis, expert assessments.

Results.The representative group of experts was characterized by a predominance of female doctors (57,0 %), persons aged 40–49 years (25.2 %) with a qualification category (76.3 %), with more than 15 years of work experience in the specialty “Psychiatry-narcology” (58.5 %). The organization of drug treatment in outpatient settings was rated “good” and “excellent” by 54.8 % of respondents, in inpatient – 71.1 %. According to experts, the factors of legal restrictions, public censure, as well as defects in the self-assessment of the nosological status of patients and the lack of general medical literacy of the population had the greatest impact on the decrease in the incidence of drug treatment for alcohol-related pathology.

Conclusion.The potential aspects of possible directions for selective influence in order to increase the appeal of the population with addictive alcohol disorders to specialized professionals and the preservation of human resources were identified.

Prinsip Miranda Rule Sebagai Hak Asasi Tersangka Dalam Sistem Peradilan Pidana Indonesia
Authors: Muammar Muammar , Baharuddin Wahdaniah
Published: March 2023

Introduction: Often in the law enforcement process there is a form of crime, neglect of obligations, human rights violations related to the civil rights of citizens in the criminal justice system and abuse of power committed by apparat.  In our criminal justice system, the rights of suspects who are the basis of human rights attached to them are often overlooked, which is detrimental to suspects.

Purposes of the Research: This research aims to find out how the Miranda Rule principle guarantees the human rights of suspects in the Indonesian criminal justice system.

Methods of the Research: The methods used in this research are normative research methods, using a conceptual approach and a statute approach.

Results Originality of the Research: the results showed that the Miranda Rule/Miranda Principle, in the form of Miranda Rights has provided guarantees for the rights of suspects. Namely, the right to obtain/contact legal counsel/advocate, and if unable to, then the right to be provided with legal counsel/advocates, the right to obtain legal assistance has been absorbed into articles 54, 55, and 114 of the Criminal Procedure Code of Indonesia, while if he is incapacitated, then the suspect has the right to be provided with legal counsel by the official concerned or through an investigator, as stipulated in article 56 paragraph 1 of the Criminal Procedure Code of Indonesia. As for the Miranda Warning (Right To Remain Silent), it is not expressly regulated, but implicitly it can be interpreted as its application in articles 52, 117 and 166 of the Criminal Procedure Code of Indonesia.
Local Chinese Dialects and Toponymy of Chinese Streets in Sibu, Sarawak
Authors:   Universiti Putra Malaysia, Wong Ling Yann
Published: March 2023

This paper aims to explore the categories, structural formation, lexicon and Romanised characteristics of nomenclature of Chinese streets in Sibu, Sarawak, in Malaysia. Sibu is the third biggest city in Sarawak, and has been labelled ‘New Foochow’ or ‘Little Foochow.’ The Foochow community in Sibu is one of the state’s largest ethnicities. As such, the Foochow culture and dialect play an important role in developing the history of Sibu. Consequently, one significant influence of the Foochow community, and its culture and dialect towards the history of Sibu is the naming of the city streets in Chinese. This study adopts a descriptive and categorical qualitative research methodology to collect and analyse research data on Chinese names of streets in Sibu, Sarawak, Malaysia, and hence employs a historical and comparative study in order to describe the categories, structure, syllabic qualities, and Romanisation of the names of Chinese roads, streets, and lanes in Sibu.
Symbolisation in Ancient Tales: A Special Reference to the Malay Text Hikayat Merong Mahawangsa
Authors:   University of Malaya, Omar Asmah Haji
Published: March 2023

Symbolisation can be interpreted as expressing what is real, not in terms of the actual thing that it is, but that which is represented in other forms. A narrative or a story that is in the mind of the writer or the storyteller is still in the form of ideas or concepts. It becomes a message when it is expressed in an organised form in the language medium that we call text. It is the text that forms the symbol to the story. In Ferdinand de Saussure’s theory of the sign, the story is the signifié or the signified, nd the text is the signifiant or the signifier. Language is an abstract and conventional symbol in the life of human beings. At the same time, there are non-language forms of symbols that have been identified as icons and indices, in particular by Charles Saunders Peirce with his theory of semiotics. This paper presents an interpretation of an ancient text, a composite of narratives of the founding of Kedah (which today is a sultanate in the north-western part of the Malay Peninsula) circa 3000 B.C.E., until the arrival of Islam circa 10th century C.E. Originally an oral tradition, the text was given a written form in the mid-18th century, using the Jawi (Malayised Arabic) script of the time. It was only in 1970 that the Jawi manuscript was transliterated using the Roman alphabet. Interpretation of the text goes through various layers of symbols, beginning with symbols in their Jawi script, and identifying words in their various forms. Making sense of linguistic elements suggests taking into account their usage within the text itself, as well as information from historical texts (in co-texts), and findings of research by relevant disciplines, specifically archaeology, geology dan geography.
Visibility Dependency of Morphosyntactic Variations: A Study on Malabar Mappila Malayalam
Authors:   Indian Institute of Technology, Jayaraj Thapasya
Published: March 2023

The paper introduces the concept of ‘visibility’ of the linguistic variant and looks at how it influences language variation by examining the morphosyntactic variations in the discourses in Mappila Malayalam, a sociolect of Malayalam spoken by the Muslim community in Northern Kerala, India namely Mappilas. The study maps the variations in serial verb constructions, case marking, and the perfect aspect marker within the socio-historical context of Mappila Malayalam. The paper also develops towards a theoretical understanding of variation based on the visibility of the variants. Throughout, I observe the variants in Mappila Malayalam that contribute to a unique identity of the community and its extended variations. As such, I adopt a Labovian framework and included aspects of discourse analysis. I advance the work on sociolinguistics and linguistic anthropology by discussing the development of a progressive model of variation, while further evidencing that the structure of the variation and social factors conjointly promote further variation concurrently dependent on the visibility of the variant, while considering instances from Mappila Malayalam.

This review considers the effect of anthropogenic sound on beaked whales2. Two major conclusions are presented: (1) gas-bubble disease, induced in supersaturated tissue by a behavioural response to acoustic exposure, is a plausible pathologic mechanism for the morbidity and mortality seen in cetaceans associated with sonar exposure and merits further investigation; and (2) current monitoring and mitigation methods for beaked whales are ineffective for detecting these animals and protecting them from adverse sound exposure. In addition, four major research priorities, needed to address information gaps on the impacts of sound on beaked whales, are identified: (1) controlled exposure experiments to assess beaked whale responses to known sound stimuli; (2) investigation of physiology, anatomy, pathobiology and behaviour of beaked whales; (3) assessment of baseline diving behaviour and physiology of beaked whales; and (4) a retrospective review of beaked whale strandings.

Information regarding beaked whales is so sparse that even the most basic aspects of their biology, such as their distribution, remain poorly defined for some species. We have reviewed the known distribution of each beaked whale species and where possible, used this information to infer its global distribution. While for some species, such as the relatively commonly recorded Cuvier’s beaked whale, the inferred distribution is likely to be an accurate reflection of the species’ actual distribution, for other lesser known species, such as the spade-toothed whale, the inferred distribution is more tentative. However, even such limited distribution information is essential when assessing and mitigating potential anthropogenic impacts on beaked whales and serves to highlight gaps in our knowledge that need to be filled if assessment and mitigation are to be successfully conducted.

Authors: Maher Mamdouh , Fayed Hany , Ali Ahmed , Zaid Ahmed , Magdy Ahmed
Published: March 2023

Purpose: Chronic kidney disease (CKD) is a major health problem and is closely linked with cardiovascular disease. Pulmonary hypertension (PH) is considered a common comorbidity in CKD patients. This study aimed at assessing the correlation between CKD and pulmonary hypertension.

Methodology: This is a retrospective study that recruited 100 Egyptian patients with stage 3 and above Chronic Kidney Disease (CKD) (KDOQI    guidelines). The study sample was composed of 100 patients with 60% overall prevalence of PH. Transthoracic echo Doppler study was performed to measure pulmonary artery systolic pressure based on tricuspid jet in the sample.

Findings: There was significant association between PH and severity of renal disease. The hemodialysed group showed a higher prevalence of PH with a more severe PH compared to groups not on regular dialysis. The study had provided evidence that PH is a common comorbidity in CKD patients and is directly proportional with the stage and duration of CKD.

Recommendations: Pulmonary hypertension should be regularly assessed using echocardiography in CKD patients specially those on regular dialysis.
A Balancing Act? Serbia’s Military Neutrality: Concept and Implementation
Authors: Harangozó Dániel
Published: March 2023

The aim of present study is to provide a concise review of Serbia’s military neutrality, both the conditions of its “genesis” in 2007 and its “operationalization” in form of strategic documents and military cooperation during the period of Serbian Progressive Party (SNS) government (2012-2021), with special emphasis on the presidency of Aleksandar Vučić (2017-2021). The paper concluded that the “genesis” and maintenance of Serbian neutrality is due to both internal political considerations, as well as Serbian diplomatic exigencies with regards to the unresolved status of Kosovo. The long-term sustainability of Serbian neutrality policy, however, cannot be taken for granted. The delicate „balancing act” between the West, Russia, and increasingly, China, might not be sustainable in the future if relations between the West (and in particular, the EU) and China or Russia, deteriorate further, or when Serbia’s EU accession process enters its „final stretch”.
Kosova and Albania in the Future : Closer or Further Apart from Each Other?
Authors: Spahiu Nexhmedin
Published: March 2023

This is a study that addresses Kosovar and Albanian identity relationships, highlighting the similarities and differences of these two communities throughout their historical journey on their respective lands. The study identifies the key historical moments that have influenced Kosovar national identity branding and concludes that the occurrence of cultural and political differences within the Albanian ethnicity since the nineteenth century has been instigated by the Serbian stance regarding Kosova. The study substantiates a clear cultural and political identity of Kosova, indicating its forthcoming solidification whilst keeping Kosovar and Albanian differences distinct, despite the eventual change in Belgrade’s stance towards Kosova. Concerns are arising from some of the voices in European diplomacy that favour Tirana’s official involvement in the Belgrade-Pristina dialogue. An analysis of the progression of their historical path, however, indicates the opposite, i.e., Tirana’s involvement in the Belgrade-Pristina dialogue would only benefit Belgrade and consequently have a negative impact on the compromises between Kosova and Serbia that the US and the European Union aim for.
The Position of the Serbian Orthodox Church and the Serbian State Regarding the Montenegrin Law on Religious Freedom
Authors: Gajić Nikola
Published: March 2023

This study analyzes the role of religion in Orthodox countries, where religion plays an important role when it comes to national identity, focusing on Serbia and Montenegro. Apart from analyzing this specific connection, the paper addresses the politicization of religion by both the state and religious institutions during the turbulent events in Montenegro between 2019 and 2020. Critical discourse analysis and the Discourse-Historical Approach is used to analyze the potential but significant shift in the ethnoreligious and nationalist discourse of Serbian Orthodox Church officials. These methodological tools are used to observe the phenomenon of politicization of religion and frame the discourse of the two actors of this process, the Serbian state and the Serbian Orthodox Church. The paper concludes that the Serbian state has to “defend” the influential position of the Serbian Church due to their historical connection. By protecting the Church, the state is showing its dedication to the preservation of the Serbian national identity.
More than one Year Later: an Evaluation of the Geopolitical Implications of the Second Karabakh War
Authors: Egeresi Zoltán
Published: March 2023

This paper describes the background and main cornerstone of the Nagorno-Karabakh conflict and reveals the main geopolitical outcomes of the second Karabakh war. It argues that the war has caused a major geopolitical shift in the region, as it has cemented Russia’s military presence in Karabakh, thus creating a frozen conflict despite the Azerbaijani victory and territorial gains. Furthermore, it has also strengthened the position of Turkey in the region and boosted the Azerbaijani-Turkish alliance, which gathered pace throughout 2021. However, other regional actors such as Iran see this change as increasingly threatening. Various attempts to create a regional forum to mend fences and establish stability have had limited results, thus tensions remain permanent in the South Caucasus.
Reality and Illusion in Colombia: What were Five Years of Transition Enough for after the Peace Agreement?
Authors: Deák Ágnes
Published: March 2023

In November 2016, Colombia’s five decades of armed conflict, which had claimed hundreds of thousands of victims, ended in a peace agreement between the government of President Juan Manuel Santos and the FARC guerrilla movement. This analysis examines the progress made in the five main points of the accord: comprehensive rural development reform, political transition, the process of demobilization and social inclusion, the eradication of illicit crop production, and the reform of the justice system. Although violence has decreased overall, and tens of thousands of families have been provided with legal ways of making a living as well as access to land and basic services, the results fall short of the stated goals, in which the changes in government and public policy that have taken place over the years have played a significant role.
The Chinese Three-child Policy in Practice : Family Protection and Family-friendly Measures at the National Level, Birth Promotion Initiatives at the Local Level
Authors: Kakuk Petra
Published: March 2023

In August 2021, the Chinese three-child policy took effect, ending the former restrictive population policy of the country. Low fertility intention is one of the reasons behind the rapid aging of the society in China, thus the new policy seeks to achieve its demographic goals by encouraging childbirth. The first part of this paper presents the family-friendly and family protection measures the central government has introduced in recent years. The second part, based on local family planning regulation amendment reports and related news, introduces how local childbearing promotion initiatives complement the central measures in the first four months of the three-child policy. The analysis concludes by outlining the future of the three-child policy. The policy is unlikely to reverse fertility decline and ageing, although it can slow down its pace and help China gain time to continue the development of its social care systems. It is worthwhile for Hungary to monitor what kind of unique subsidies China introduces to promote childbirth in the future.
The Impact of the Introduction of the Euro in Croatia
Authors: Šiljak Dženita
Published: March 2023

Croatia, the newest member of the European Union, is set to introduce the euro as its currency in January 2023. Although it was announced that Croatia had fulfilled the Maastricht criteria for monetary union membership in May 2022, the country did not meet the criterion on the general government debt rate. This paper analyses Croatia’s readiness to join the euro area beyond meeting the Maastricht criteria. While monetary union membership has its positive sides, by joining, a country loses one of the most important tools of managing its economy – monetary policy. If the economy is strong and competitive enough, with efficient institutions and stable fiscal policy, the loss of monetary policy can be mitigated. However, Croatia’s decision to join the euro area is hasty, as if the country just wanted to join a prestigious club. This lack of preparedness could have major negative effects on one of the least competitive economies in the EU.
Elections in Bosnia and Herzegovina: the Wind of Change between War and Peace?
Authors: Šiljak Dženita
Published: March 2023

Bosnia and Herzegovina (BiH) held presidential and parliamentary elections on 2 October 2022, amid the most severe political crisis since the 1992-1995 war. Inefficient institutions and problems created by political leaders led the country to the bottom of economic and political statistics in Europe. While citizens were hoping for a change, it did not come as the nationalist parties won the majority again. The change of the election law imposed by the High Representative during the election night did not bring much hope either. The country is still stuck in its nationalist rhetoric and the lack of dialogue among the decisionmakers. It is difficult to see how the newly elected political leaders will be the ones finally taking responsibility for bringing change.
Serbia and the Russia–Ukraine War: Implications and Challenges II.
Authors: Harangozó Dániel
Published: March 2023

The outbreak of the Russia-Ukraine war in February 2022 has had a marked effect on the Western Balkan region. Among the countries of this region, Serbia is in a unique situation due to its military neutrality, and the fact that it follows a balancing foreign policy between the Western powers on the one hand, and Russia, Turkey, and China on the other hand, also maintaining close political, economic, and security ties with the latter two powers. The second part of the paper continues to review the consequences and challenges of the war on Serbia by examining the energy domain. Russian exposure in Serbia’s energy sector, apart from the near-total reliance on Moscow for gas imports, is compounded by the fact that the most important oil company of the country, Naftna Industrija Srbije (NIS) is majority-owned by Gazprom Group. As with other countries in the Central and Eastern European region as well as wider Europe, the diversification of sources and decreasing the reliance on Russian energy will take considerable time for Serbia. Cooperation both with Serbia’s neighbours and the countries of the region (e.g. Bulgaria and Greece) will play a significant role in the diversification of both sources and supply routes.

Thermal power plants generate more than half of world's electric energy. The question of optimisation of thermal power plants is very relevant for the regions of Russia's Far East. This paper is dedicated to researching the possibilities of reducing loss of electric energy for steam condensation. An analysis of thermal power plant's operating modes was conducted in searching of ways to optimise them. Excessive steam generation was pointed out as a main drawback of thermal power plant's operation, it is not fully coordinated and often exceeds the needs of users in electricity and heat. The issue of reducing energy losses by analyzing the operating modes of the thermal power plant, the amount of electricity consumed and weather conditions depending on time is considered. The use of algorithms based on artificial neural networks to solve the problem of predicting the required amount of energy is proposed.

In article are considered a concept objectivization «the happiness» in the English, Russian, German and French phraseology. In the process of cognitive-discursive analysis, the ethno-cultural component of the concept is expressed, which makes it possible to determine the specifics of the concept of "happiness" in the ethnic linguistic picture of the world. Using information from various authoritative sources that report about phraseological units, to establish semantic and functional correspondences of phraseological units with the concept of "happiness" and divide them into appropriate semantic groups. Phraseological combinations were selected by searching for an equivalent from another languages and a continuous selection of keywords: «счастье», «happiness», «Glück», «bonheur». In the identified Russian phraseological units, their English, German and French equivalents, the concept of "happiness" and its representative lexemes are represented through certain conceptual features. Cultural images with specific markings become an ethno-cultural component, they are used in the structure of phraseological units of other languages. Various ethno-cultural components were observed in the presented phraseological units. It proved to be that native German speakers have the concept of "happiness" as an opportunity to master new stages in life; for the French people happiness is associated with an oak tree as a symbol of wisdom and longevity, favorable conversation, luck; for Russian—speaking representatives of culture happiness is joy and flight.

In the modern world, the tasks of improving the quality of processing the results of environmental monitoring of the seabed require careful study of individual unconventional innovative solutions. Today, real-time studies of the state of the underwater marine environment in the Arctic region of Russia are carried out using autonomous underwater robotic systems equipped with modern automated systems for collecting and processing information from special on-board television cameras. These technologies make it possible to identify adverse environmental factors and the presence of foreign objects with the further transfer of information to the corresponding coordination center for monitoring the environmental situation of the bottom surface. At the same time, for better and more detailed analysis, it is necessary to provide video broadcasting with high resolution. Instead of hydroacoustic underwater systems that have been used for many decades, optical systems for transmitting and receiving information using a laser beam have become widely used. The reason for this transition is the extremely low transmission rate of the video data stream to surface objects, which was the beginning of the creation of open high-speed underwater communication systems with a wider bandwidth. The article discusses the problem of evaluating the effectiveness of a wireless underwater laser communication system and its organization, the functional structure of the system is given. It is proposed to use a generalized criterion for the efficiency of the system based on a change in the intensity of laser radiation, which does not take into account the "human factor" and is based solely on the natural and technical components.

When comparing ancient and modern rye cultivars, in addition to the difference in height, differences in the content of photosynthetic pigments in tissues are also noted. However, it remains unclear whether the change in pigment content is related to the change in plant architectonics. Plants of winter rye cultivars which differ in plant height were collected under the conditions of crop rotation of the Krasnoyarsk Research Institute of Agriculture. The concentrations of chlorophylls a and b and carotenoids were determined in the flag leaves and stems of winter rye at the “booting-earing” stage. The weight of the above-ground biomass was determined with the hay-harvest method. The stem length increases from the Arga cultivar to the cv. Krasnoyarskaya universalnaya and further to the cv. Yeniseyka. The relationship between the level of photosynthetic pigments and the height of plants as well as their wet biomass was assessed. A trend line toward an increase in the content of chlorophylls and carotenoids, assessed per leaf area, and biomass was revealed against the background of a decrease in stem height. When assessing the pigment content per mass of organs, the trend is less pronounced and is observed only when comparing the varieties Arga and Krasnoyarskaya universalnaya with the highest cultivar Yeniseyka.

Purpose: Crude oil is used in folklore medicine to treat various forms of diseases and in most cases in combination with medicinal plants. Studies have reported that Cnidoscolus aconitifolius possess medicinal properties. The present study investigated the effect of different concentration of Bonny light crude oil and Cnidoscolus aconitifolius on some biochemical parameters of Wistar rats. The rats were orally exposed to different concentrations of Bonny light crude oil and Cnidoscolus aconitifolius leaf extract individually and in combination.

Methodology: After an exposure period of 21days, the results revealed that Bonny light crude oil and the leaf extract at concentrations of 250 and 500mgkg-1b.wt can induce damage to the liver and kidney within 21days of consecutive administration. This is shown in results of histological analysis gotten from the liver and kidney tissues.

Findings: This study revealed that the induction of the leaf extract of Cnidoscolus aconitifolius and Bonny light crude oil at concentrations of 250 and 500mgkg-1b.wt for 21days may affect the liver and kidney.

Contributions to theory, policy and practice:Therefore, it is recommended that the use of this leaf extract and Bonny light crude oil at concentrations similar to the ones used in this study should be discontinued.
