Aim. To study the predictors of adverse events in hypertensive (HTN) patients, including those with chronic respiratory diseases (CRDs).

Material and methods. Regression analysis evaluated clinical and anamnestic data and blood pressure (BP) in outpatients with stage II-III HTN (n=156): 49 patients had asthma, 20 — chronic obstructive pulmonary disease; age — 63,4±8,8 years, women — 72,4%, followup duration 29,3±8,0 months. The outcomes included in the composite primary endpoint (EP) were registered in 32 patients (death, major cardiovascular events and complications), while the secondary EPs were registered in 57 patients (hospitalizations, emergency calls, temporary disability due to cardiovascular disease/CRD, hypertensive crisis, exacerbation of CRD, pneumonia, respiratory failure), and tertiary EP — in 76 (other significant diseases/conditions, including increased blood pressure without hypertensive crisis, requiring correction of regular therapy).

Results. Predictors of primary EPs were the decrease level of nocturnal diastolic BP (DBP) (β=-5,335, p=0,026), nocturnal DBP variability (β=1,796, p=0,007), blood leukocyte level (β=0,241, p=0,039); secondary EPs — systolic blood pressure ≥170 mm Hg in history (β=1,305-1,641, p=0,037-0,017), statin use (β=-0,997, p=0,037), CRD (β=0,734, p=0,023), blood platelet level (β=-0,008, p=0,022); tertiary EPs — only CRD (β=1,082, p<0,0001).

Conclusion. Patients with HTN need complex multifactorial prevention. It is necessary to improve the control of office and ambulatory blood pressure, blood lipids, especially in the presence of CRD, to improve the control of CRDs themselves. The method of 24-hour blood pressure monitoring should be used more often in routine practice, including assessing the degree of nocturnal blood pressure reduction and its variability.

Aim. To study the two-year survival rate of patients with various types of cerebrovascular accident according to the outpatient part of the REGION-M registry.

Material and methods. The outpatient part of the REGION-M registry included 684 patients assigned to the City Polyclinic № 64, discharged from the F. I. Inozemtsev City Clinical Hospital (Moscow) in the period from January 1, 2012 to April 30, 2017 with a confirmed diagnosis of stroke or transient ischemic attack (TIA). Of these, 514 (75,1%) patients had an ischemic stroke, 52 (7,6%) — a hemorrhagic stroke, and 118 (17,2%) — a TIA.

Results. The lowest two-year mortality (11%) was observed in patients who underwent TIA (p<0,001) compared with ischemic and hemorrhagic stroke. The relative risk of death for ischemic stroke was 2,0 (95% confidence interval (CI): 1,13-3,55) (p<0,05), and for hemorrhagic stroke — 2,51 (95% CI: 1, 22-5,15) (p<0,05) relative to patients with TIA. Mortality in patients with ischemic or hemorrhagic stroke did not differ significantly — 32,3 and 36,6% (p>0,05). The mean age of patients who underwent TIA was significantly less than the age of patients with hemorrhagic or ischemic stroke. With increasing age, the survival of patients significantly worsened in all types of strokes. In addition, multivariate analysis adjusted for age showed remained significant effect of the stroke type on survival as follows: the relative risk of death for ischemic and hemorrhagic stroke was 1,99 (95% CI: 1,12-3,53) (p<0,05) and 2,45 (95% CI: 1,19-5,02) (p<0,05).

Conclusion. Mortality in patients with stroke was significantly lower after TIA than in any type of stroke and did not differ between subgroups of patients with ischemic and hemorrhagic stroke.

Published: January 2023

The redistribution of body composition components in heart failure (CHF) is an urgent and poorly understood issue. Despite the significant impact of a decrease in muscle mass, redistribution of fat mass on the course and prognosis of HF, body composition is rarely taken into account in the treatment of this disease. In this regard, the purpose of this review was to systematize the available data and draw the attention of clinicians to this problem. The data presented in the review make it possible to consider the components of body composition as controllable factors, the normalization of which improves the prognosis in patients with HF. The study of pathophysiological mechanisms for the development of body composition anomalies in HF will make it possible to search for new therapeutic targets. Assessment of body composition will make it possible to develop an individual strategy for the treatment of HF, including a set of non-drug measures.

Published: January 2023

Despite significant progress in the development of novel methods for the prevention and treatment of cardiovascular diseases, their prevalence remains high, which is largely due to low adherence of patients to drug and non-drug preventive interventions. Motivational counseling (MC) is a unique technology that makes it possible to activate the patient’s desire to change their behavior towards a healthy one. The review presents an analysis of the literature on MC technology and the possibilities of its application in cardiology practice. Research data show the effectiveness of MC in improving the nutrition profile, physical activity, weight loss, smoking cessation, control of glycated hemoglobin in patients with diabetes, improving outcomes in patients with heart failure, increasing adherence to therapy, etc. Conducting MC using telemedicine technologies seems promising. The training of specialists is of paramount importance, since the effectiveness of this type of counseling largely depends on the accuracy of the consultant’s adherence to the essence and technologies of MC.

Thrombophlebitis of the superficial lower limb veins is one of the most common complications of chronic vein disease. Nowadays a long-term (at least 45 days) subcutaneous injection of fondaparinux sodium or heparin in combination with elastic compression of the limb is recommended for treatment of superficial vein thrombosis with a moderate risk of thrombus propagation to deep venous system. However, long-term use of anticoagulants is not always possible and sometimes contraindicated. Endovenous laser ablation (EVLA) around thrombus-free junction of great or small saphenous veins without subsequent long-term use of anticoagulants seems to be a promising intervention for treatment of acute thrombophlebitis of varicose superficial veins.

The prospective single-center randomized open-label clinical trial was dedicated for comparison the efficacy and safety of three following treatments options for patients with acute thrombosis of the varicose great saphenous vein and location of thrombi in the trunk and/ or its large inflows: EVLA close to saphenous vein junction without anticoagulation, EVLA and 7 days of anticoagulation and noninvasive treatment with anticoagulation for 45 days (subcutaneous injections of the fondaparinux 2,5 mg). Class 2 compression stockings are used in all patients. Adverse outcomes are recorded at 7, 45 and 90 days after randomization. These include the progression of superficial vein thrombosis, recurrent superficial vein thrombosis, thrombosis involvement of the superficial segment of the perforating vein up to the fascia, deep vein thrombosis according to compression ultrasound, and pulmonary embolism with symptoms. Bleedings according to the World Society of Thrombosis and Hemostasis and the Academic Research Consortium classification as well other complications are also recorded. The first 30 patients included in the study have a low incidence of venous thrombosis risk factors and localization of the thrombus relatively far from the saphenofemoral junction. EVLA resulted in persistent cessation of venous blood flow at the intervention site. New episodes of venous thrombosis were noted only in the group of medical treatment — deep vein thrombosis of the contralateral tibia 5 days after stopping of 45-day treatment with fondaparinux and thrombus in the recanalized inflow of the great saphenous vein without involving its trunk at the 21st day after stopping of 45-day injection of fondaparinux. There were no complications in the area of intervention and bleedings.

Hypertension (HTN) is a leading risk factor for the development of cardiovascular diseases. In recent decades, the rapid development of genetic tests, in particular genome-wide association study (GWAS), has made it possible to identify hundreds of nucleotide sequence variants associated with the development of HTN. One approach to improve the predictive power of genetic testing is to combine information about many nucleotide sequence variants into a single risk assessment system, often referred to as a genetic risk score. Within the framework of this review, the most significant publications on the study of the genetic risk score for HTN will be considered, and the features of their development and application will be discussed.

Left ventricular non-compaction (LVNC) is a rare, genetically and phenotypically heterogeneous disease, which is often accompanied by diagnostic difficulties.

Aim. To demonstrate several generations of a family with LVNC with various clinical and phenotypic manifestations of the disease (dilated and isolated types of LVNC) with an identified rs397516387 variant of the TPM1 gene.

Material and methods. Based on the multicenter registry "Myocardial Non-compaction", a family with a familial form of LVNC was selected. Next generation sequencing (NGS) was performed on an Ion S5 system (Thermo Fisher Scientific, USA) using Ampliseq technology. Variant was verified using Sanger sequencing on an Applied Biosystem 3500 Genetic Analyzer (Thermo Fisher Scientific, USA). For clinical interpretation, variants in the genes associated with LVNC with a minor allele frequency <0,1% were selected in the gnomAD database (v2.1.1). Results. Variant rs397516387 was found in 5 family members, including the proband. Further examination revealed LVNC in 2 additional family members. The proband and the proband’s uncle had a dilated type of LVNC, and the proband’s mother had an isolated type.

Conclusion. The paper presents several generations of a family with different phenotypic manifestations of LVNC and rs397516387 variant in the TPM1 gene. The beginning of genetic screening from a proband, a thorough collection of a family history and further detailed genetic screening of relatives led to the identification of rs397516387 variant in 4 more family members, which in turn made it possible to conduct an additional examination to confirm the diagnosis and prescribe timely drug therapy.

Aim. To provide data on the diagnostic and prognostic value of questionnaire survey for post-COVID-19 syndrome during screening and regular medical check-ups of employees, as well as preventive medical examinations.

Material and methods. This single-center cross-sectional comparative study involved 1120 people (92,1% of the general population — all employees of the organization), including 195 men (67,3% of the general population) and 925 women (79,5% of the general population). All participants filled out the post-COVID-19 syndrome (PS) detection questionnaire, the Hospital Anxiety and Depression Scale and the QAA-25p Adherence Assessment Questionnaire. Potential adherence to treatment was calculated using the SCOPA software. Statistical processing was performed using tools adapted for medical and biomedical research (Python language; Sklearn, NumPy, Pandas libraries) and Statistica 6.13 (StatSoft Inc., USA).

Results. As a result, 47% of respondents noted at least one symptom that reduces the quality of life and/or performance efficacy. In all subsamples, women reported symptoms more frequently than men. The most informative indicators associated with post-COVID-19 syndrome are age (Mann-Whitney U test, p=0,042), number of PS symptoms (Mann-Whitney U test, p=0,001), severity of PS symptom (Mann-Whitney U test, p= 0,004) and adherence to health care (Kruskal-Wallis H test, p=0,021). An increased level of anxiety is associated with all the analyzed symptoms, depression level with 6 symptoms, age with 5 symptoms, insufficient compliance with 3 symptoms.

Conclusion. PS questionnaire should be included in a comprehensive survey program of persons undergoing medical examinations. It is necessary to develop algorithms for the treatment and diagnosis of patients that take into account the number and severity of individual symptoms separately for men and women with consideration to their COVID-19 epidemiological status, as well as age and markers of anxiety, depression, and adherence to treatment.
The main barriers to the social integration of older people
Authors: Kutovaya Svetlana
Published: January 2023

The article analyzes the main barriers to the social integration of older people. The relevance of the chosen research topic is determined by the existing need to address many issues related to the increase in the proportion of older people, which leads to the transformation of the socio-demographic structure. It should also be taken into account that today old age is not only physiology, but also a combination of psychological, social, socio-cultural and other factors. However, not all of them have a positive effect on the social integration of older people. The problem of social exclusion after retirement comes to the fore, the search for the meaning of one's existence is more acute, there is a feeling of uselessness by society, which leads to depression and loneliness. In addition, there is the problem of society's perception of the elderly person himself. Often he is not positioned as an equal participant, as a social unit, and his social potential is not used. To eliminate these problems, it is necessary to understand the process of social integration, namely, what social barriers prevent positive changes in the life of an elderly person, exclude the possibility of benefiting society and being an active participant in it. Based on sociological surveys, it was revealed that socio-psychological (depression, loneliness, misunderstanding with relatives, etc.) have a greater influence on social integration; socio-economic (the level of material income; exposure to fluctuations in the market economy; the impact of external adverse factors; shortcomings in the pension system; lack of preferences from the state, lack of work in rural areas, etc.); labor (reduction of pensioners in the workplace; poor organization of the system of pre- and retirement employment); social and medical (unavailability of medical care and its low quality, understaffing of polyclinics and hospitals with the necessary specialists, constant increase in prices for medical services and medicines, etc.); socio-cultural (a small number of non-profit public organizations for the elderly, poor organization of leisure, etc.); ageist stereotypes (negative experience of communication with the elderly, self-stereotyping, estimation of values in society, etc.).

Published: January 2023

Masonry construction is popular around the world, but the use of mortared masonry presents numerous challenges. In recent decades, masonry construction systems incorporating interlocking masonry units have been proposed to eliminate mortar. The interlocking between masonry units can be achieved using specially shaped units. This paper presents a comprehensive experimental study to determine the behaviour as well as basic material properties of one such semi-interlocking mortarless masonry. The experiments included testings of ungrouted masonry units, prisms, and wallets. In addition, masonry prisms and wallets with grouted cores were also investigated to study the effect of grouting. A detailed description of the construction procedure is explained. The failure mechanisms, maximum strengths, force–displacement relationships, and modulus of elasticity of the samples are obtained and contrasted with the relevant results from the literature. Finally, recommendations are made that may assist material model development required for micro- and macro-modelling of mortarless masonry. The new information generated in this research will enable better understanding of the behaviour and properties of semi-interlocking mortarless masonry and will be useful for validating numerical models in future research.

Published: January 2023

Activated carbon has found key applications in the adsorption of polluted industrial dyes in water. In this work, macadamia husk biochar (MHC) was prepared using a household pyrolysis kiln before being activated with phosphoric acid (H3PO4) to obtain macadamia-husk-activated carbon (MHAC). A preliminary study was made on two activation conditions of MHC:phosphoric acid (w/v), 1:1 and 1:3, for the removal of malachite green (MG) dye. Analysis of experimental results revealed that the adsorption process was highly controlled by the time of contact, MHAC particle size, MHAC dosage and initial dye concentration. With the use of an MHAC particle size of 125–202 μm, an MHAC dosage of 6 g/l and a contact time of 120 min, the removal efficiency reached >99% at an MG concentration of 40 parts per million (ppm) before being degraded to around 75% at 70–80  ppm MG. Impregnation with zinc nitrate hexahydrate (Zn(NO3)2·6H2O) on the MHAC surface could maintain a removal efficiency of >99% at all initial dye concentrations (40–80 ppm), so the maximum removal capacity increased to ∼130 mg/g.

Una de las zoonosis de gran impacto es la Leishmaniasis visceral causada por el parásito protozoario Leishmania infantum, transmitida por el vector hembra hematófaga infectada denominada Lutzomyia longipalpis siendo el principal reservorio el perro doméstico, considerada una patología tropical olvidada en 98 países a nivel mundial especialmente en Colombia desde sus primeros casos en humanos y caninos. El objetivo del trabajo fue desarrollar una revisión sistemática de literatura acerca del comportamiento epidemiológico de Leishmaniasis Visceral con el transcurso de los años en Colombia, utilizando tres bases de datos reconocidas (Google Académico, PubMed y Dialnet) así como el gestor de referencias bibliográficas Mendeley y otras fuentes bibliográficas, inicialmente se encontraron 180.610 documentos de los cuales 21.673 duplicados se eliminaron, dejando 158.937 estudios restantes, posteriormente se realizó una tercera selección de 11.127 artículos y por último 126 artículos seleccionados abarcan las temáticas de interés. La distribución de los casos de la enfermedad van desde el Valle del río magdalena como Huila, Tolima hasta los departamentos de Sucre y Córdoba con una alta frecuencia, además se resalta que en los caninos los datos sobre la ocurrencia no son actualizados por la falta de estudios. En conclusión, la Leishmaniasis visceral se considera un problema epidemiológico y de Salud pública debido al contacto entre el principal reservorio y el hombre. En Colombia a través de los años se ha encontrado que los datos sobre los reportes en los humanos se ha desarrollado sin interrupciones en las zonas de mayor riesgo (Sucre, Córdoba, Santander, Tolima, Huila) mientras que en los caninos la búsqueda y notificación no ha sido específica e incluso incompleta presentándose limitaciones en el momento de determinar la ocurrencia actual de la enfermedad, por lo tanto es fundamental fortalecer los sistemas de vigilancia para generar información verídica sobre los casos dependiendo directamente del conocimiento de la LV por parte de los veterinarios y entes responsables.

Published: January 2023

We consider the customization of the UCB strategy, which was first proposed by J. Bather for Bernoulli two-armed bandit, to the case of a Gaussian multi-armed bandit describing batch data processing. This optimal control problem has classical interpretation as a game with nature, in which the payment function of the player is the expected loss of total income caused by incomplete information. The goal is stated in minimax setting. For the considered game with nature, we present an invariant description of the control with a horizon equal to one, which allows to perform computations in two ways: using Monte-Carlo simulations and analytically by dynamic programming technique. For various configurations of the considered game with nature, we have found saddle points, which characterize the optimal control and the worst-case distribution of the parameters of the multi-armed bandit.

Authors: Заремба Анастасия Павловна , Zaremba Anastasiia
Published: January 2023

This paper describes a differential game of $n$ persons in which the utility functions of the players have a hybrid form, namely, they are changed at a random moment in time. With the help of integration in parts, the form of the payoff functional is simplified. For the cooperative scenario the problem of time-consistency of the optimality principle chosen by the players is studied and a solution is proposed in the form of an adapted imputation distribution procedure. The differential investment game is considered as an example.
A class of game models with equilibrium, stable and pareto-optimal solutions
Authors: Горелик Виктор Александрович , Gorelik Victor , Золотова Татьяна Валерьяновна , Zolotova Tatiana
Published: January 2023

The paper proposes game models with pay-off functions being convolutions by the operation of taking minimum of two criteria one of which describes competition of players in some common (external) sphere of activity and the other describes private achievements of each player (in internal sphere). Strategies of players are distributions of resources between external and internal spheres. The first criterion of each player depends on strategies of all players; the second depends only on the strategy of given player. It is shown that, under some natural assumptions of the monotonicity of the criteria, such $n$-person games are characterized by the fact that the Nash equilibrium exists, is strong, stable, and Pareto-optimal, and in two-person games in the Stackelberg equilibrium, the leader and the follower win no less than in the Nash equilibrium.

Published: January 2023

Green living walls can improve the aesthetic quality of a building and moderate the temperature within it. The purpose of this paper is to examine whether the green wall has any effect on the interior temperature of the building in the hot and cold months of the year. Temperatures on an outside wall as well as on research and control areas were monitored to capture temperature data for a one-year period that encompassed all seasons: sunny, cold and wet. The findings of this research contribute to the knowledge of the effects provided by green living walls in terms of cooling and heating, the influence on the proximity microclimatic conditions, and overall energy transfer. Heat flux of 20-100 W/m2 was found indicating an insulating effect that brings about cooling in the interior of the building. During summer months a cooling effect of 2-4 °C was observed, while the opposite effect was observed during winter in that the temperatures did not drop by much but provide a insulating effect of 2-3 °C higher than it was for the control area. Altogether, green living walls could be implemented to reduce and insulating interior living conditions and therefore reduce building energy demands.
The effect of overburden and confined stress state on cave mining propagation
Authors: Schoeman N.K. , Jacobsz S.W. , Kearsley E.P. , Wesseloo J.
Published: January 2023

A physical modelling approach was adopted to simulate the process of cave mining propagation at various horizontal to vertical stress state ratios, and image data was captured and used to characterize the resulting failure mechanisms. Image processing was integrated into the study to determine minor principal strains in models to identify where critical extensional strains had been exceeded relative to crack propagation. The study exhibited a scale factor magnitude of 119 using a calculated critical extensional strain value of 0.014% for the modelling material used. It was perceived that cave propagation occurred through successive parallel extensional 'fracture bands' in all cases, as noticed in models of prior studies, deviating from that described by the Duplancic model. Cracks tended to bisect regions of minor principal strain equal to the critical extensional strain, which suggests 'fracture banding' is an acceptable failure mode for brittle, rock-like materials. Moreover, it was found that models with lower horizontal to vertical stress ratios (K ratios) showed a greater degree of vertical development of the caving mechanism (at similar vertical stresses), while the vertical extent of the cave was suppressed in models with higher K ratios. Models subjected to larger vertical stresses experienced slower cave formation in latter time-steps. These models exhibited larger two-dimensional caved perimeters and areas, respectively.

Published: January 2023

The effects of utilizing recycled tailings pond water from the flotation plant at the Mining Company of Guemassa (MCG) on galena recovery and selectivity towards chalcopyrite (RPb-Cu) , sphalerite (RPb-Zn), and pyrrhotite (RPb-Fe) were studied at bench scale. The results showed that recycling the tailings pond water in the lead circuit without addition of fresh water gave a good flotation performance in terms of lead recovery (Rpb) (75%) and selectivity towards the other metals: RPb-Cu (54%), RPb-Zn (60%) and RPb-Fe(65%). This allows the water to be recycled at least four times. However, increasing the d80 from 100 um to 160 um currently used at the MCG plant had a negative effect on the lead flotation performance.

Previously unknown error detection characteristics by types and multiplicities in modified Hamming codes code words are established. The rules for constructing this modification of Hamming codes are described. Detailed characteristic tables of codes with data vectors lengths m = 4...16 are given. The considered code's error detection properties brief analysis is given. The results obtained in the study can be effectively used in the digital computing devices with controllable structures synthesis, as well as in the self-checking concurrent error-detection (CED) circuit synthesis using the Boolean complement method. The modified Hamming codes key property is the impossibility of 100 % double error detection in all code word bits when any single and double errors that occur only in data bits are detected. That is why it is recommended, when synthesizing a CED circuit using the Boolean complement method, to convert only those functions that describe the operating functions of the diagnostic object that will form the modified Hamming code control bits, and to separate the converted and non-convertible outputs into two groups of independent outputs. The experiment results with test combinational circuits presented in the article confirm the effectiveness of their use in the CED circuit synthesis by the Boolean complement method.

Currently, the replacement of relay of railway automation and telemechanic is carried out at regular intervals without taking into account the actual number of relay switch. This method has such disadvantages as the lack of maximum and uniform exhaustion of the relay resource during operation and address planning of its replacement. The article proposes a scientific method that allows to manage the resource of relay of railway automation and telemechanic at the stage of its operation based on objective data on the values of its actual number of switch. To calculate the actual number of relay switch, simulation of the operation of relay and relay-processor systems of railway automation and telemechanic is used. The input data for the model of calculating the actual number of switch relay are the operation of the station (any movements of trains) and events that are recorded on the remote controller of the station attendant. The events of remote controller are changing the indication of the remote control lamps of the elements of the railway automation and telemechanic system (cancellation of the route, artificial opening, etc.). The article proposes to take data about the movement trains from technical diagnostics and monitoring systems. The data set, took as a result of processing information from technical diagnostics and monitoring systems, is compared with the algorithm (rules) of the operation of the railway automation and telemechanic system operated at the railway station or stage. On the results of comparing data from technical diagnostics and monitoring systems with the rules of operation of the railway automation and telemechanic system, it is formed a list of relay, describing the operating procedure of the railway automation and telemechanic system. The output data of the model is a list of relay with the actual number of relay switch. Data on the values of the actual number of relay switch allows determining the objective terms of its replacement and transition to address planning for the replacement of relay.

The importance of geography in modern life is rather difficult to overestimate, because it is precisely thanks to it that we understand the phenomena and processes that take place in the world and have a different nature (natural, social, economic). That is why this science is an integral part of students' education, a subject that affects the formation of schoolchildren's worldview. However, often children may not fully understand why they need to study this discipline, or even not be interested in it at all. Actually, that is why it is relevant to consider the methodology of organizing and holding subject weeks in geography. During their implementation, many forms of work are used at the same time, which contribute to the interest of students in the specified subject. However, the subject week is not only a special form of learning, but also a period when the teacher can reveal his creative potential as fully as possible. The imagination of the teacher and the variety of forms, methods and means in the aggregate can help to create such a complex of activities that will not only increase the motivation of students to study and prove to them the benefits of geography as a science, but will also be a kind of useful leisure for them, will allow them to show their own abilities, orient themselves in choosing a profession and acquiring important communication skills: testing yourself as a leader or working in a team with other schoolchildren. During the organization of the subject week, the teacher can show his own creativity, using both existing forms of extracurricular work and filling them with new content, and creating and implementing new ones. The week of geography is an opportunity for the subject teacher to prove himself and introduce novelty into the educational process. As the analysis of the experience of pedagogical workers and our own showed, one should always take into account the school's capabilities and the age characteristics of students and create such activities that would be interesting for students and at the same time informative.

In today's world, there is little that can interest children in learning about the world around them. They are used to spending a lot of time in their gadgets. Namely, the school was created in order to develop children's abilities, skills and outlook. Fortunately, we have such an event as an excursion. Thanks to them, we can show students the world around as it is; just a walk near the school or a trip to the forest to show the beauty of this world, and most importantly - of their native land, and encourage them to love the Motherland. The goal of the bachelor thesis is to develop an educational excursion that combines knowledge of the native land and motivates to preserve nature. In the process of research, the main approaches to defining the concept of "excursion", the functions and methodical stages of the educational excursion were analyzed. Materials on the natural conditions of the Ponornytsk OTG and the Mezyn National Nature Park itself have also been developed. The next stage was the development of the author's excursion "Paths of Mezyn Park". 7 display objects were selected for the event. To learn the excursion material, a mini-game "Field of Miracles" was developed and a homework assignment was offered: creating a wall-newspaper "Vegetation of Mezyn Park".

In this study, we apply the non-linear dynamical systems theory for the assessment built on recurrence-quantification analysis technique for characterizing—differentiating non-linear electro encephalograph (EEG) signals dynamics. The technique offers convenient quantifiable data plus information over normal, tumultuous, or probability and statistical stochastic properties of inherent systems dynamics theory. The R.Q.A-established processes as the quantifiable mathematical features of non-linear electroencephalograph signals dynamics. Average amount of mutual information (AAMI) applied to compute highly applicable feature-manifestation sub-sets out of R.Q.A-built centered-features. The chosen features were then fed into the computer using artificial intelligence based neural net-works for clustering the data of encephalograph-signals to identify ictic(i.e.,ictal), inter ictal, followed by state of controls. The study is implemented by validating R.Q.A with a data base for various issues of categorization. Results showed that the combination of five selected features created on AAMI attained the precision of100% and proves dominance of R.Q.A. Nonlinear dynamical control systems theory and analysis techniques centered on R.Q.A can be used as an appropriate methodology for distinguishing the non-linear systems dynamics of encephalograph signals data also epileptic seizures tracing.
Painting memory engram by biologically active messengers –The molecular time travel for the search of memory
Authors: Ganguly Krishnendu
Published: January 2023

Using MRI and PET methods, neuroscience has made significant progress in understanding the episodic events of the human brain under varied cognitive situations throughout the last century. However, the higher resolutions of the memory locus, which consists of a neuro-glial ensemble for episodic memory, are unclear and must be clarified. Additionally, attempts have been made to create new nano technologies for mapping complete brains and related engrams with single neuro-glial accuracy and resolution in the hopes of unlocking the secrets of the brain by delving into Brain Activity Map (BAM). This hypothetical research is the first of its kind to suggest a novel method for understanding episodic memory in mouse brains by mapping brain activity at the functional connectome (engram) level and focused on neuro-glia-ECM (Extracellular Matrix). I propose to paint the memory engram at the neuro glia-ECM canvas of the mouse brain by engineering and inserting novel "Biologically Active Messengers: Bidirectional Messengers (BM)s/ Alternative Clones (AC)s and Transcriptional/ Translational Messenger (TM)s" coupled with different colour tags into transgenic mice via Transposon and Recombination, followed by behavioural analysis and Clarity. The BMs will be produced in all neuro-glial cells via a bicistronic promoter (Neuro-glia specific promoter + Tetracycline Responsive Element) led by a tetracycline transactivator gene driven by an immediate early gene (c-Fos/ Arc), whereas the TMs will be expressed via an endogenous promoter. The viability of all constructions (BMs, ACs, and TMs) as well as the process of painting will be tested in cortical/ hippocampal culture by chemically generating long term potentiation (cLTP). Fear consolidation (Fear context and Recall by contextual cue) tests will be administered to adult transgenic mice, followed by Clarity coupled Immunostaining to investigate the neuro-glia-ECM ensemble after whole brain imaging using a Light Sheet Microscope. Finally, the steady state behaviour of normal mice will be compared to the episodic picture of a colourful painted engram. At both the functional connectome and activity levels, this holistic painting method will highlight cognition over multiple timelines of a working memory region. Bidirectional Messenger (Biological Boomerang) has huge implications in neuropsychiatric illness, generation of artificial blood, cancer treatment, and regenerative medicine in the near future, according to my intuition.

Published: January 2023

Sturge-Weber syndrome (SWS) is a type of neuro-cutaneous diseases which is seen in 1 in 50,000 populations and affects both the sexes equally. It usually manifests with a facial Port Wine Stain (PWS). Facial port-wine stains are usually isolated findings, however, when associated with cerebral and ocular vascular malformations they form part of the classical triad of Sturge-weber syndrome (SWS). The prevalence of PWS is estimated at three to five children per 1000 live births; there are ~26 million people worldwide with PWS birthmarks. The majority of facial PWS (~90%) are unilateral in a trigeminal dermatomal distribution. Here, we report a case of 39 years old female with SWS who presented with classical triad of SWS i.e., bilateral port-wine stain, epilepsy and severe glaucoma.

Authors: Saadi Saadi I. , Mohammed Ibrahim K.
Published: January 2023

The main purpose of this paper is to obtain optimum power from a Photovoltaic (PV) panel and deliver it to a load system under standard irradiance and temperature weather conditions. Standard Boost DC-DC converters and bidirectional Buck-Boost DC-DC converters work as voltage controlling units for the power provided from the PV panel, which is used to charge the battery and supply suitable voltage signal to AC load. MPPT technique, based on two control algorithms, Particle swarm optimization (PSO) and Incremental Conductance (INC), is used to extract maximum power from the solar cells. Matlab/ Simulink environment is adopted to simulate the proposed PV power system. Simulation results are presented and analyzed based on transient and steady-state performance parameters. The performance results of the PV array system under the Standard Test Conditions (STC) showed that the INC-MPPT control algorithm can provide a
