Authors: Risandi Lara , Holinesti Rahmi
Published: June 2023

Purple sweet potato (Ipomoea batatas L. Poir) is a vine that contains lots of anthocyanins and fiber, very beneficial for human health. Jam is a food product with a gel consistency so that the formation of gel in jam is highly desirable. The obstacle in making purple sweet potato jam is that the gel formation is not strong enough. So it is necessary to add food ingredients to form a gel, namely Carboxymethyl Cellulose (CMC). The addition of CMC aims to determine the effect of adding CMC on the quality of purple sweet potato jam with the effect of adding CMC of 0.5%, 1%, 1.5% and 2% on the quality of purple sweet potato jam from organoleptic tests. This research was conducted in January - February 2023 at tata boga workshop, Department of Family Welfare, Faculty of Hospitality Tourism, Universitas Negeri Padang. This type of research was a pure experiment using a completely randomized design (CRD) consisting of 5 treatments and 3 repetitions. To analyze the quality of the purple sweet potato jam, it was carried out through an organoleptic test involving 3 expert panelists. The data obtained is then tabulated and followed by statistical analysis (ANOVA), if Fcount ≥ Ftable then it will be continued with Duncan's test. The results showed that the addition of CMC had an effect on texture being soft and easy to spread, while the other indicators had no effect in terms of color, aroma and taste. The best research results of Carboxymethyl Cellulose (CMC) were found in treatment X4. The overall highest achievement score was color 3.67 (2%), aroma 3.89 (0%), soft texture 4.00 (2%), texture easily smeared 4.00 (2%), sweet taste 3.89 (2%) and purple sweet potato flavor 3.67 (2%). the addition of CMC had a significant effect between 0.5%, 1%, 1.5% and 2% on the quality of purple sweet potato jam, namely the quality of the soft texture and the texture easily smeared with purple sweet potato jam. The best quality test results for purple sweet potato jam with the addition of CMC were in treatment X2 with the addition of 2% CMC.

The theology of nonviolence in the writings of Petr Chelčický during the late Middle Ages
Authors: Maíz Jordi
Published: June 2023

The article explores the emergence of the Hussite movement and the establishment of egalitarian communities that embraced a lifestyle without taxes or private property. The concern of the authorities and the resulting internal conflicts highlighted significant changes and internal struggles. Leaders such as Jan Žižka adopted more aggressive and violent stances, considering Prague and other cities as enemies. In this context, Petr Chelčický, influenced by the Taborites, emerges as a prominent figure. His critical writings towards the clergy and the Church defend pacifism, egalitarianism, and communism, advocating for the autonomy of the Czech church and opposing German domination. Chelčický distances himself from the Hussites due to his rejection of violence and in his hometown, he develops an extensive body of work proposing a life free from materialism and power conflicts. His local influence is significant, leaving a legacy in the religious and social reforms of the era and beyond.

En segunda instancia, se evaluó la asociación estadística entre el indicador sintético de calidad de vida y dos indicadores, uno de naturaleza económica como el PBG (2003) y el otro de orden demográfico, la tasa de crecimiento anual intercensal para el periodo 2001-2010. Los resultados evidencian la presencia de desigualdades territoriales en referencia a la calidad de vida de la población y el potencial explicativo de las variables independientes propuestas.
Loosening religion. O o que torna um artefato “religioso” na história da religião sul-levantina?
Authors: Klein Cardoso Silas
Published: June 2023

As discussões e críticas recentes ao conceito de “religião”, que se intensificaram na arena internacional e iniciaram a “virada reflexiva” nos estudos da religião nos últimos trinta anos, tiveram pouco impacto no campo da história da religião sul-levantina antiga. Enquanto o uso de fontes “extrabíblicas” e a colisão com outras disciplinas desencadearam uma revolução silenciosa no campo com profundas implicações, “religião” continua a ser usado como conceito autoevidente. Como resultado, a atribuição de “religiosidade” a objetos, práticas e estruturas continua propensa a projeções anacrônicas baseadas em um conceito subteorizado de religião e suposto senso comum do objeto. Dentro desse panorama, o artigo discute o que torna um artefato religioso na história da religião sullevantina e classifica estratégias de atribuição de “religiosidade”. Os limites dessas estratégias são ainda discutidos em dois estudos de caso. O artigo, por fim, argumenta que pesquisadores estão perdendo religião (losing religion) por suas estratégias ocidentais restritivas e sugere que, em vez de restringir, pesquisadores continuem afrouxando o conceito de religião (loosening religion).
Is alumina suitable for solid phase extraction of catecholamines from brain tissue?
Authors: Mirković Duško , Beletić Anđelo , Savić Miroslav , Milinković Neda , Matutinović Marija Sarić , Jančić Ivan
Published: June 2023

Occupational and environmental toxicology specialists find catecholamine fluctuations in brain tissue relevant for research of neurotoxicity, such as that induced by manganese or zinc, pesticides, industrial solvents, plastic, air pollution, or irradiation. Considering that catecholamine tissue concentrations are generally very low, their extraction requires a reliable and optimal method that will achieve maximum recovery and minimise other interferences. This study aimed to evaluate whether the aluminium (III) oxide (Al2O3, alumina) based cartridges designed for catecholamine isolation from plasma could be used for solid-phase extraction (SPE) of catecholamine from the brain tissue. To do that, we homogenised Wistar rat brain tissue with perchloric acid and compared three extraction techniques: SPE, the routine filtration through a 0.22 µm membrane filter, and their combination. In the extracts, we compared relative chromatographic catecholamine mobility measured with high performance liquid chromatography with electrochemical detection. Chromatographic patterns for norepinephrine and epinephrine were similar regardless of the extraction technique, which indicates that the alumina cartridge is good enough to isolate them from brain tissue. However, the dopamine pattern was unsatisfactory, and further experiments are needed to identify the issue and optimise the protocol.
Estimating flavonoid oxidation potentials: mechanisms and charge-related regression models
Authors: Miličević Ante
Published: June 2023

In this paper, I tested our quadratic regression models for the estimation of flavonoid oxidation potentials based on spin populations, the differences in the net atomic charges between a cation and a neutral flavonoid, between a radical and an anion of a flavonoid, and between a radical and a neutral flavonoid on a larger set of flavonoids (N = 35). By including six new flavonoids (5,6,7-trihydroxyflavone, 3,3’,4’,7-tetrahydroxyflavone, 3,7-dihydroxyflavone, 4’,7-dihydroxyflavone, 4’,5,7-trihydroxyisoflavone, and 6-hydroxyflavone), we created a respectable calibration set of 35 flavonoids with their oxidation potentials all measured at the same conditions by the same experimentalist. The best model was based on the mean values of the three variables using differences in the net atomic charges (R
2 = 0.970, S.E. = 0.043), which are connected with the three different mechanisms of electrochemical oxidation, SET-PT, SPLET, and HAT.

Authors: Sarah A. Al-Ameri  , Lafta S. Kadhim
Published: June 2023

To interpret the provenance 0f Injana Formation,  20 sandstone samples of Injana Formation were collected  from Zawita and Dekala areas north Iraq (10 for each sections ), then  thin section have been done sildes. The petrographic study showed that the sedimentary, metamorphic and igneous rock fragments, quartz (mono&polycrystalline) and feldspars (microcline, orthoclase and plagioclase) make up the main grain components of the sandstone. Carbonate cement is more common cementing minerals, and the matrix is subordinate. The percentage of mono-quartz and sedimentary, igneous rock fragments are greater than the amounts of feldspar and poly-quartzand metamorphic fragments. A diagenetic processes were represented by the carbonate, iron oxides and evaporite cements, as well as compaction, cementation, and dissolution. The majority of the rocks of Injana Formation’s provenances are sedimentary and igneous, with minor amounts of subordinate metamorphic rocks. These sandstones are considered to be immature and classified as immature Litharenites type. The tectonic provenances that are extrapolated from petrographical results are transitional and lithic with effect of uplifting of Alpaine oroging recycled origin which are derived from the order rocks during the Miocene age.

Using a new algorithm in Machine learning Approaches to estimate level-of-service in hourly traffic flow data in vehicular ad hoc networks
Authors: Ahmed Ibrahim Turki  , Saad Talib Hasson
Published: June 2023

The primary goals of transportation agencies and researchers studying traffic operations are to ease traffic and increase road safety through the use of vehicular ad hoc networks. Agencies can't achieve their goals without reliable and consistent data on the current traffic situation. The Level-of-Service (LOS) index is a helpful measure of freeway traffic operations. Conventional fixed-location cameras and sensors are impractical and expensive for gathering reliable traffic density data on every road in large networks. Flow data is a new, low-cost option that has the potential to boost safety and operations. This study proposes an algorithm for hourly LOS assessment by incorporating flow data provided by the MIDAS (Motorway Incident Detection and Automatic Signaling) system. The proposed algorithm uses machine learning techniques to classify LOS data based on the flow of traffic. The input features that are subject to prediction are a group of technical indicators. The real-world LOS was determined by analyzing data from stationary sensors. The outcomes demonstrate that technical indicators can be utilized to enhance the accuracy of LOS estimation (Random Forest= 93.1, k-nearest neighbors = 92.5, and Support Vector Machine = 91.4). The current work introduces a novel approach to the selection of technical indicators and their use as features, which allows for highly accurate short-term prediction of LOS estimation.

Switzerland's good offices in light of the American hostage-taking in Iran (1979-1981)
Authors: Khasanov Azat
Published: June 2023

Switzerland's neutrality during the Cold War allowed it, without joining any of the opposing blocs, to take an active part in international politics. This, in particular, was reflected in the so-called good offices and a series of protective mandates of Switzerland in Iran. The article presents a brief historical digression into the process of development of diplomatic relations between Switzerland and Iran. The purpose of the article is to determine the role of Swiss diplomacy in negotiations on the release of American hostages in Iran (1979-1981). The study was carried out on the basis of declassified archival documents, a significant part of which is being introduced into scientific circulation for the first time (documents of the US State Department and the Swiss Federal Department of Foreign Affairs devoted to the settlement of the crisis with American hostages). This determined the scientific novelty of the study. The use of the historical-genetic method allowed us to study the genesis of bilateral relations between Switzerland and Iran before the 1979 Islamic Revolution. A narrative (descriptive-narrative) method was used to describe Switzerland's diplomatic services to the United States in Iran after the 1979 Islamic Revolution. Through the structural and functional method, it was possible to identify the mechanisms of Swiss diplomacy during secret meetings between the American and Iranian sides and the execution of the protective mandate to represent the interests of the United States in Iran. The historical-retrospective method helped to evaluate the results of Switzerland's "good offices" in Iran from the perspective of time distance.
Conceptual analysis of the narrative strategy of the text of the propaganda speech from the position of the post-Romanov psychoanalytic approach
Authors: Ivanova Victoria
Published: June 2023

The article presents the author's version of narrative analysis based on the methodology of post-Romanov political psychoanalysis and discourse analysis of the text of a propaganda speech. The concepts of the master signifier, the points of attachment, the double movement of signifiers in the structure of the narrative as the basis for the internalization of the ideas and values of the narrative by the addressee of communication are actualized. The matrix of the university's discourse is considered as a constructive basis that ensures the promotion and functioning of the narrative. The analysis of the case of the speech of the US Secretary of State Colin Powell at the UN Security Council on February 5, 2003 is given. The initial theoretical positions and conclusions are correlated with the data of public opinion polls conducted by the Gallup Institute.The author's main contribution to the theory of narrative analysis is the approbation of the conceptual apparatus of political psychoanalysis to propaganda texts. The study of the phenomenon of internalization of the narrative of war in the mass consciousness requires a deep understanding of the driving forces underlying the processes under study. For the first time, the media text is analyzed from the perspective of a psychoanalytic approach, with the possibility of defining and describing specific reference points of a speech that determine its structure and final result. The proposed study lays the prerequisites for the further development of the concept of the narrative life cycle and the formulation of the concept of the counter-narrative, the definition of the inherent limitations and opportunities of this life cycle.
Lagrangian Simulation Methodology for Large-Eddy Simulations of Prefilming Air-Blast Injectors
Authors: Carmona Julien , Treleaven Nicholas C. W. , Odier Nicolas , Cuenot Bénédicte
Published: June 2023

A Lagrangian framework is proposed to address liquid film and atomization modeling in large-eddy simulations (LESs) of aeronautical air-blast injectors. The Lagrangian liquid film model of O’Rourke and Amsden (“A Spray/Wall Interaction Submodel for the KIVA-3 Wall Film Model,” SAE International TP 2000-01-0271, Warrendale, PA, 2000) is improved by introducing a subgrid contact angle to better predict the film height and the resulting film dynamics. Next, the phenomenological the primary atomization model for prefilming air-blast injectors (PAMELA) proposed by Chaussonnet et al. (“A New Phenomenological Model to Predict Drop Size Distribution in Large-Eddy Simulations of Airblast Atomizers,” International Journal of Multiphase Flow, Vol. 80, April 2016, pp. 29–42) for primary atomization at the prefilmer edge is enhanced to deal with complex geometries. This model is able to predict the droplet-size probability density function from the prefilmer height and flow conditions. The original formulation relied on correlations valid for flat plates to determine the gas boundary-layer thickness, and it required a gas velocity at film height to be set by the user. These two points make its use difficult for complex configurations where there is no simple correlation for the gas boundary-layer thickness and the gas velocity at film height cannot be a priori estimated. An embedded methodology, named the automatic PAMELA, is therefore proposed in this work to automatically determine these two quantities in the simulation. For each cell of the prefilmer edge where atomization occurs, the gas boundary-layer thickness is estimated by analyzing the local velocity profile thanks to Lagrangian probes; and the gas velocity is computed from the local film height by assuming a logarithmic velocity profile. Finally, the film and primary atomization models are coupled to a secondary atomization model, and they are assessed on an industrial air-blast aeronautical injector. The average droplet velocity profiles and Sauter mean diameters are compared against experimental phase Doppler particle analyzer measurements, and they demonstrate the ability of the proposed framework to perform Lagrangian LESs of liquid injection in complex geometries.
Variability in Perception of Dyspnea in the Context of Additional Respiratory Resistance: Cross-Sectional Observational Exploratory Study
Authors: Byalovsky Yu. Yu. , Rakitina I. S.
Published: June 2023

Background. In various situations healthy people may experience breathlessness caused by high altitude, breath-holding, anxiety or panic driven by stressful events, and, very often by physical activity. However, variability in perception of dyspnea in healthy individuals is yet to be explored. The present study analyzes the variability of dyspnea perception in healthy people in the context of additional respiratory resistance.

Objective — to assess the variability in perception of dyspnea in healthy individuals against a step-up increase in additional respiratory resistance, and to evaluate the relationship between dyspnea perception and physical activity levels.

Methods. A cross-sectional observational exploratory study involved healthy individuals aged 19–25. The study was conducted at the Department of Pathophysiology, Ryazan State Medical University named after acad. I.P. Pavlov (Russia), in the period from November 2018 to June 2019. A total number of individuals under study comprised 42. Study participants were subjected to additional respiratory resistance, when dyspnea perception was estimated using a modified Borg scale. Then all participants were divided into three groups according to the tertiles in their perception: slight perception (Borg score < 2; n = 13), moderate perception (Borg score 2–5; n = 19) and high perception (Borg score > 5, n = 13). The study involved determination of body mass index, maximal airway pressure, pulmonary function, physical activity by means of IPAQ (International Physical Activity Questionnaire) and 6MWT (6 Minute Walking Test). Data analysis was performed using IBM SPSS Statistics 17.0 (USA).

Results. The study included 42 healthy individuals. The level of dyspnea perception was determined as slight (low), moderate (medium) and high in 13, 19 and 10 participants, respectively. Perceived level of breathlessness did not significantly correlate with age, gender, body mass index, physical activity, maximum airway pressure or pulmonary function test results.

Conclusion. Perceived dyspnea caused by a step-up increase in additional respiratory resistance varied significantly. The perception of dyspnea was determined as slight in 31% of participants, moderate in 45% and high in 24%. The authors did not reveal a correlation between dyspnea perception and physical activity level (via IPAQ or 6 Minute Walking Test).

This is the fi rst biota description of the regional nature monument Mys Devich’y Peski, located on the west coast of Lake Khanka (Primorsky Krai, Russia). The Amur softshell turtle Pelodiscus maackii (Brandt, 1857) and a large bivalve mollusk Lanceolaria chankensis Moskvicheva, 1973, listed in the Red Book of the Russian Federation, inhabit the coastal waters, while Oxytropis chankaensis Jurtz., a coastal endemic of Lake Khanka, grows on the sandy beaches. This natural monument is one of the few places of successful breeding of the Amur softshell turtle after the catastrophic rise of water in the lake. The local group of P. maackii is dominated by mature individuals of medium size with a track width of 190–229 mm. Average number of tracks of these reptiles per 1 km of coastline is 38.2, maximum is 60 (n = 109). We have noted a high number of predators – raccoon dogs Nyctereutes procyonoides (Gray, 1834) and otters Lutra lutra Linnaeus, 1758, ravaging turtle clutches.The geographical location of the Mys Devich’y Peski natural monument should be clarifi ed in its cadastral case, and the monument should be assigned with a zoological profi le.

Platelet-rich fibrin: A promising regenerative material
Authors: Uike Suvidha , Malik Rajvir , Salve Apoorva Vinayak
Published: June 2023

Periodontal regeneration is a process involving biological events such as cell adhesion, migration, proliferation, and differentiation in an orchestrated sequence. It is well known that platelets play a key role in hemostasis and the wound healing process. Platelets were introduced as regenerative potential. Choukroun et al. (2001) first described platelet-rich fibrin (PRF). It is the second generation of platelet concentration. It consists of a natural fibrin matrix. It is autogenous fibrin made up of the patient’s blood free from anticoagulants. It is three-dimensional architecture consisting of the specific composition of leukocyte and platelet-rich fibrin biomaterials. Various technique has been used in the preparation of PRF but Choukroun’s PRF technique is the most common and easy technique developed in France. The patient’s blood was taken at around 5 ml which is collected in each of the two sterile vacutainer tubes with a 6 ml capacity without anticoagulant and centrifugation. PRF is used in various fields such as endodontics, oral and maxillofacial surgery, periodontics, and tissue engineering. It is more economical and easy preparation than other grafts. PRF should be handled properly before it shrinks and gets dehydrated. It is the most successful periodontal regenerative material.

Poster - Les Italiens de 1946, pas seulement des mineurs. Les Italiens de la Céramique Nationale, de Vicenza à Welkenraedt (Éditions de la Province de Liège, juin 2021)
Authors: Mignano Nathalie
Published: June 2023

En 1946, les Italiens ne viennent pas tous travailler dans les mines : 130 travailleurs de la province de Vicenza arrivent en 1946-47 dans l’entreprise Céramique Nationale de Welkenraedt. L’usine, désaffectée, a été détruite. Par ailleurs, les descendants des travailleurs restés sur place paraissent parfaitement intégrés. Cette immigration est-elle vouée à l’oubli ? La recherche, basée sur des témoignages et la consultation des registres de population de la commune, met en lumière la diversité des profils de ces immigrés. Elle se penche sur leurs trajectoires, leurs conditions de vie et de travail en Italie puis à Welkenraedt, et leur devenir après une expérience de durée variable dans l’entreprise. Enfin, elle interroge la deuxième génération sur ses liens avec les racines transalpines. Ce travail, qui se veut une contribution à la mémoire intrafamiliale et à la mémoire collective, a été publié avec le soutien de la Province de Liège.
Poster - Les causes politiques de l’immigration italienne vers la Belgique après la Seconde Guerre mondiale
Authors: Mascitelli Germano
Published: June 2023

Malgré un retour formel à la démocratie, une part importante des jeunes qui quittent l’Italie après la Seconde guerre mondiale le font poussés aussi par le climat politique qui touche personnellement leur vie. Dans la première partie on présente des histoires de lutte et répression qui nous aident à saisir ce climat. Dans la seconde, on donne des exemples de cette émigration politique vers la Belgique. En effet, leur défaite à la fin du cycle de conflictualité sociale de l’après-guerre avait rendu la vie impossible à ces travailleurs politiquement engagés.
Selection of the best-performing climate reanalysis model for the Sakha (Yakutia) Republic, based on mean annual air temperature
Authors: Tananaev N. I.
Published: June 2023

Mean annual air temperature (MAAT) values for the historic (1961 – 1990) and modern (1991 –2020) reference climatic periods, collected from 91 meteorological stations across the Sakha (Yakutia) Republic were used in an evaluation of the performance of several modern reanalysis products. The model error analysis shows GHCN-CAMS to be the best-performing MAAT reanalysis product, with the lowest absolute error, below 0.15°С, and best concordance with observation data. This product can be used as a ‘baseline climate’ in geospatial modeling and future climate forecasts. Its main limitation is monthly temporal resolution. The ERA5-Land product, having higher spatial and temporal resolution, can be used to track changes in climate-related variables between periods, but its absolute MAAT values deviate systematically and non-concordantly from the observed data. Parameters of the linear regression relating ERA5-Land data to observations are shown to be time-dependent, hence such evaluation yields increased uncertainty limiting the applicability of this approach. All reanalysis products underestimate the observed MAAT increase at stations across central Yakutia, which suggests the appearance of stable ‘urban heat islands’ in the recent decades.

Multi-electron redox chemistry is traditionally a domain of transition metals which are well-known to show multiple valence states with a vast variation of physical and chemical properties. Redox-active organic molecules, on the other hand, usually present only two valence states. Herein we demonstrate the design and preparation of a very simple organic molecule benzo[1,2-c:3,4-c':5,6-c'']tris([1,2,5]thiadiazole) 2,2,5,5,8,8-hexaoxide (tripak) that shows unprecedently rich redox chemistry and is capable of accepting up to six electrons in five consecutive reduction steps. Tripak is a derivative of the thermodynamically unstable [6]oxocarbon C6O6, where all C=O groups were used to form three dioxothiadiazole rings. It is the first representative of the new poly(dioxothiadiazole) family of compounds comprising three dioxothiadiazole groups fused together to form a simple rigid highly symmetrical skeleton with a single benzenoid ring in the middle. The electron withdrawing character of the dioxothiadiazole rings is responsible for the reversible multi-electron redox behavior which enabled its isolation and complete structural and physicochemical characterization in five-out-of-six oxidation states: 0, -1, -2, -3 and -4. Depending on the number of electrons, the tripak system represents different types of aromaticity (non-aromatic, Hückel or Baird) and redox-related multifunctionality: tripak0 shows record-strong anion-π binding of halides which is comparable with the energy of coordination bonds, tripak1- and tripak3- are two very different S = 1/2 radical states with tripak1- exhibiting very long spin-spin relaxation time at room temperature placing it among the most promising molecular qubit candidates, tripak2- is a blue dye with strong red fluorescence and finally tripak4- is an open-shell singlet diradicaloid system with a singlet-triplet gap close to zero.

Published: June 2023

This study explores the impact of vibrational strong coupling (VSC) on intrinsic physical and chemical properties of molecules within plasmonic nanocavities. We demonstrate how the formation of polariton states decreases the stage temperature required to induce the dehydration of copper sulfate pentahydrate by as much as 14˚C. Confocal Raman microscopy in conjunction with an “open” cavity design facilitated sub-wavelength spatial mapping of the modified chemistry, which was localized to regions with the largest local density of optical states (LDOS). These findings underline the role of strong light-matter hybridization for enhancing energy transport between the cavity substrate and the molecules, effectively eliminating their temperature difference. This research offers critical insights into the mechanisms of VSC-modified chemistry, paving the way for novel, tailor-made catalytic processes hinging on fine-tuned energy exchange.

Threats to network information security are currently increasing both in number and seriousness. Today's hackers are mostly focused on attacking end-to-end systems and finding weak points in people. These strategies include pharming, phishing, and social engineering. These assaults include a stage where malicious Uniform Resource Locators (URLs) are used to trick visitors. Consequently, harmful URL detection is growing in popularity. The use of machine learning and deep learning algorithms to identify malicious URLs has been proven in several academic articles. In this study, we propose a malicious URL detection system that makes use of machine learning approaches based on proposed URL behaviors and attributes. Bigdata technology is additionally being utilized to enhance the detection of risky URLs based on peculiar behavior. A novel set of URL traits and behaviors, a machine learning algorithm, and big data technologies make up the suggested detection technique. The trials' findings imply that the suggested URL characteristics and behavior can significantly improve the ability to identify potentially harmful URLs. This shows that the suggested method might be regarded as the best and most convenient way to find counterfeit URLs.
Improvement of methods of algolization and biomelioration of the Rostov NPP cooling pond and the near dam part of the Tsimlyansk reservoir

The intensive multiplication of cyanobacteria which results in the phenomenon of «blooming of water» is one of the most complicated and urgent problems of many reservoirs. Highly eutrophic water bodies in southern regions subject to regular anthropogenic impact are in the most vulnerable position. The level of manifestation of «water bloom» in the upstream zone of the Tsimlyanskoye reservoir in the most productive areas of the open and closed coastal zone, as well as in the central zone is often quite high and requires regular implementation of a set of measures to improve water quality. At present, to combat the spectrum of negative effects caused by eutrophication processes and hyperproduction of cyanobacteria, bioremediation methods are actively applied, one of which is algolization of water bodies by planktonic strains of green microalgae Chlorella vulgaris Beijer

The drive of the reactor control and protection system (CPS) is a system of normal operation, important for safety. Malfunctions of the drives of the ARC type CPS are often the initial events for accidents leading to unauthorized downtime. The currently existing standard methods for monitoring the parameters of the CPS do not allow for a reliable assessment of the condition of the drives. In this paper, it is proposed to implement an approach that provides an increase in sensitivity when recognizing the states of the drives of the ARC control system by processing the initial signals, which are vibroacoustic signals registered on the lid of the upper unit of the VVER reactor. A procedure for processing diagnostic signals using singular spectrum analysis is proposed. The proposed approach differs from the known ones by the presence of a scaling procedure, which is implemented by multiplying the eigenvalue matrices by the gankelized matrices of the source data. Due to scaling, the necessary sensitivity increase is provided. The expected increase in sensitivity is based on the fact that the eigenvalues reflect the structure of the signals, which changes significantly under the influence of the defect. The proposed method was used to process vibroacoustic signals registered on the lid of the upper block of the VVER reactor unit. Experimental studies were carried out at the test stand of Izhorskiye Zavody OJSC. The results of processing experimental data indicate a high quality of diagnosis. The hypothesis was clearly confirmed that the difference in the structure of diagnostic signals of serviceable and faulty equipment can manifest itself in the eigenvalues of the gankel signal matrices. The approach proposed in the article to the processing of diagnostic signals is easily amenable to automation and can be implemented in the development of a diagnostic system for the drive of an ARC-type CPS.
