Published: April 2023

The article discusses the prospects for the development of intelligent computing systems. It is determined that at present the most promising direction in this area is based on the idea obtained as a result of biological research on the development of biocomputers, special types of molecular microcomputers using the concept of nerve cell DNA as the basis for calculations. In this regard, the structure and functioning of the nerve cell is considered in detail. Based on the consideration and analysis of the works of physiologists on the structure and functions of a biological neuron, it was found that the information perceived by a person is stored in the neurons of the brain at the molecular level, it also suggested that the nucleus and endoplasmic reticulum are elements of processing, transformation and storage of temporary memory. In addition, it was assumed that the nerve cell of the brain is a molecular, analog supercomputer that performs the analysis, synthesis, processing and storage of information. Huge volumes of information perceived by a person from the moment of his birth and throughout his life are stored in a nerve cell. There are about 100 billion neurons in the human brain, with each neuron containing millions of membrane-bound ribosomes. A detailed consideration of the functioning of a biological neuron from the position of a cybernetic system approach led to the understanding that the structure and functions of the ribosomes of a nerve cell almost completely coincide with the structure and functions of a Turing machine. It is shown that, in fact, a Turing machine is a processor consisting of a logical device and external and internal memory. A neuron can be considered as a molecular multiprocessor supercomputer, since in a neuron, an analog of the logical structure of the ribosome, and external and internal memory are transfer RNA and informational RNA. An example of the implementation of the simplest version of the Turing machine is given. In conditions of successful development of this direction, the possibilities of computers of the future are enormous. A brief description of the neuron-like element and the neural-like growing network is given. Their application in the technology of molecular machines will lead to the creation of a machine brain similar to the human brain.

Published: April 2023

The rapid development of electric transportation in the world is due to significant economic and ecological advantages. The Ukrainian government also is planning to develop a national strategy and plans for the implementation of electric transportation. But the additional load poses challenges for Ukraine’s Integrated Power System. The analysis of the influence of electric transportation introduction on Integrated Power System operation would facilitate its effective government implementation. The aim of this paper was to estimate the effect of implementation volumes of electric transportation on the Integrated Power System operation, fossil fuel consumption, greenhouse gases, and pollutant emissions. A set of calculations was carried out for electric transportation volumes from 30 to 420 thousand electric vehicles by step 30 thousand based on a program and information complex simulating the operation of Ukraine's Integrated Power System, which has been developed in the Institute of General Energy of the National Academy of Sciences of Ukraine for the past few years. The calculations show that the share of nuclear power plants in Ukraine’s Integrated Power System increases according to the growth of the electric vehicles fleet. Therefore, it is expected to decrease fuel consumption as well as greenhouse gases and pollutants emissions. Fuel intensity is reduced by approximately 5% for electric transportation volume of 150 thousand and approximately 8% for 300 thousand. Specific emissions decrease faster due to the ratio of coal and gas power plants. Fuel intensity considerably varies from 0.07 (Summer) to 0.15 (Winter) tce/kWh. In general, the additional load from the implementation of electric transportation positively affects the energy system of Ukraine, increasing the efficiency of its operation by reducing specific fuel consumption. It should be noted that such trends are observed exclusively for Ukraine due to the specific structure of Ukraine's Integrated Power System with the large share of nuclear energy. Keywords: electric transportation, Ukraine’s Integrated Power System, greenhouse gas emissions, pollutant emissions.
ELECTRIC ENERGY STORAGES

The article provides an analytical review of reverse-acting electric energy storage devices that can be used to solve systemic problems of the United Energy System of Ukraine. The need for the use of electric energy storage is due to the existing shortage of maneuverable capacities of the United Energy System and the construction of solar and wind power plants, which, due to the stochastic mode of operation, are a significant destabilizing factor. Due to the lack of market pricing mechanisms, the possibility of adjusting the rates of the "green" tariff, and the decrease in the cost of solar and wind power plant technologies, a rapid increase in their number and capacity has been observed in recent years. At the beginning of 2021, the installed capacity of solar power plants was 6.87 GW, and wind power plants – was 1.31 GW, and by 2030, their growth is planned to be 10.5 GW and 5.0 GW, respectively. Without adequate regulatory capacity, this can lead to catastrophic consequences, as happened in South Australia. The conducted review and analysis showed that the dominant technology of electric energy storage in the world is hydro-storage power plants, the implementation costs of which are about 260 USD/kWh. Compressed air energy storage is the cheapest technology but needs to be located near the energy systems of natural caves. Accumulator systems of energy storage are developing at a fast pace, the costs of their implementation are 311-520 USD/kWh with a tendency to decrease by 2030 by about 25%. They are the most promising for work in energy systems. These storage devices can be used to regulate frequency and power, reduce electricity flows, reduce voltage fluctuations in electrical networks, consolidate daily schedules of electrical loads, prevent overloads of electrical networks and transformers, increase the reliability of electricity supply, increase the stability of the operation of solar and wind power plants, as well as for commercial purposes in various segments of the electricity market of Ukraine. Keywords: energy system, electricity storage, power, capacity.

The advantages and disadvantages of some most common methods of quantitative analysis used in processing of synphytoindication data were analyzed. These methods enabled reflection of important ecological characteristics of plant communities and assessment of the nature of their topological and regional differentiation characterizing α-, β-, γ-diversity. We also examined current debatable issues regarding the use of scales of ecological indicator values and methods of their correct comparison based on bringing to a single "denominator". The visual aspects of the gradient analysis used in assessment of topological differentiation of habitats based on the establishment of various types (vector, combinative and complex) of ecological and coenotic profiles are considered. We focused our attention on the application of optimal models of ordination methods (detrended correspondence analysis – DCA, non-metric multidimensional scaling – NMDS). The use of cluster analysis reflected in various methods of dendrogram constructing was evaluated. The analysis of the above methods allows us to evaluate the efficiency of their use in various aspects of synphytoindication techniques. This allows us to use such data for forecasting and modeling biocoenoses changes and development, for assessment and classification of biotopes, landscape structure (ecomer), zoning (ecochor), as well as for evaluation of the resistance of vegetation to the influence of external factors. The methods and approaches of mathematics and cybernetics are expected to be more widely used in geobotany in the future, since many pressing ecological issues related to non-linear development, emergent changes in the ecosystems properties and search for critical thresholds cannot be solved in a traditional way.

Published: April 2023

Today there are smart cities that, through the use of information technologies, sensors, and specialized infrastructure, focus their efforts on improving the quality of life of their inhabitants. From these efforts arose the need to analyze and represent data within a system to make it useful and understandable to people, for which dashboards emerge. The objective of these systems is to provide users with information to support decision-making, so it is essential to adapt the visualization of the information provided to their needs and preferences. However, the analysis of adaptability through user interaction and its benefits is a topic still under exploration. This paper analyzes the literature on information visualization in adaptable dashboards for smart cities. Based on the elements of adaptable dashboards identified in the literature review, we propose an adaptable dashboard architecture, identify the main characteristics of the users of a smart city dashboard, and build an adaptable dashboard prototype using user-centered techniques.

Published: April 2023

This paper studies the occurrence of insecure deserialization in communication between client-side code and the server-side of a web application. Special attention was paid to serialized objects sent from JavaScript client-side code. Specific patterns of using serialized objects within the client-side JavaScript code were identified and unique classes were formulated, whose main goal is to facilitate manual and automatic analysis of web applications. A tool that detects a serialized object in the client-side code of a web page has been designed and implemented. This tool is capable of finding encoded serialized objects as well as serialized objects encoded using several sequentially applied encodings. For found samples of serialized objects, the tool determines the context in which the found object appears on the page. For objects inside JavaScript code, the tool identifies the previously mentioned classes by mapping the vertices of the abstract syntax tree (AST) of the code. Web application endpoints were checked for whether programming objects were deserialized on the server side, after obtaining the results of the study. As a result of this check, previously unknown vulnerabilities were found, which were reported to the developers of this software. One of them was identified as CVE-2022-24108. Based on the results of this research, a method was proposed to facilitate both manual and automated searches for vulnerabilities of the "Deserialization of untrusted data". The proposed algorithm was tested on more than 50,000 web application pages from the Alexa Top 1M list, as well as on 20,000 web application pages from Bug Bounty programs.

Authors: Jiménez Samantha , Favela Jesús , Quezada Ángeles , Ramachandran Raj , Juárez-Ramírez Reyes
Published: April 2023

People who have dementia (PwD) experience deteriorating executive functions, in particular their working memory, and therefore find it hard to complete multistep tasks or activities of daily living. There is no doubt that during the pandemic, PwD and their caregivers were particularly vulnerable, often isolated which affected their mental and physical health. Their ability to live independently was hampered, fomenting depression in the PwD and burnout on informal caregivers. Information technology can support dementia care improving the quality of life of PwD and easing the burden on caregivers. There is an increasing demand to support informal caregivers and improve their well-being by making dementia challenges less severe. This study uses qualitative techniques to design a model with technological strategies based on semi-structured interviews applied to seven informal caregivers from two different countries. Based on these interviews we developed design insights for implementing solutions to help informal caregivers take care of their PwD at home using conversational agents. We hope that the findings presented in this study will help researchers, and developers design solutions that can support PwD and informal caregivers.

Published: April 2023

Software process has been studied from various perspectives, among them, the human factor is one of the most important due to the intrinsic social aspect of the discipline. This study aims to explore the benefits of using Belbin's role theory in tasks —team and individual— related to the software development process, particularly in Database Design (DB) Design. In this paper two controlled experiments with students are presented. In the first experiment integrated teams with compatible roles identified in the students and teams integrated through a traditional strategy were compared, during the task of DB conceptual design. In the second experiment, individual students were the experimental subjects, the performance of the Belbin roles identified in them were compared, in the task of the DB logical design. The dependent variables in both experiments were the effort in the task, and the quality of the generated design. Results in the first experiment did not show significant differences in both variables, a possible limitation was the complexity of the task. The second experiment also did not show significant differences in the effort variable; however, in the variable related to the quality of the logical design, the monitor-evaluator role presented significant differences when compared with the other six identified roles; these results are consistent with previous studies identified in the literature. We plan to continue experimenting with other tasks in order to get a deeper understanding of applying the Belbin’s theory in software process to accumulate experiences.

Authors: Dávila René , Aldeco-Pérez Rocío , Barcenas Everardo
Published: April 2023

A tender process consists in competing offers from different candidate suppliers or contractors. The tender winner is supposed to supply or provide a service in better conditions than competitors. Tenders are developed using centralized unverified systems, which reduce transparency, fairness and trust on the process, it also reduces the ability to detect malicious attempts to manipulate the process. Systems that provide formal verification, decentralization, authentication, trust and transparency can mitigate these risks. Satisfiability Modulo Theories provides a formal analysis to prove correctness of tender offers properties, verified properties ensures system reliability. In addition, one technology that claims to provide decentralization is Blockchain, a chain of distributed and decentralized records linked in a way such that integrity is ensured. This paper presents a formal verified and decentralized proposal system, based on Satisfiability Modulo Theories and Blockchain technology, to make electronic procurement tenders more reliable, transparent and fair.

This study uses big data, namely the socio-economic 2019 data. The focus of this research is Education. Education is an important factor in life, but in West Sumatra using the socio-economic 2019 data it is still in the low category and far from the national average. In this study will predict the factors that influence education in West Sumatra with the data classification method. Methods for classifying large amounts of data have been developed, including Machine Learning. Machine Learning is a field of technology that is currently being widely used to create algorithms with large data (big data). The machine learning method used is Naive Bayes and Bagging. Furthermore, the two models were tested and showed that the Naive Bayes model gave the best performance compared to the Bagging model based on the values of accuracy, sensitivity and specificity. So the Naive Bayes model is the best machine learning model for predicting the factors that affect education, namely household members, gender and regional classification.
A snapshot review of future-oriented standards for cement, admixtures, and concrete: How Africa can spearhead the implementation of green urban construction materials
Authors: Schmidt Wolfram , Kanjee Janina , Motukwa Gosego , Olonade Kolawole , Dodoo Alex
Published: April 2023

The existing cement and concrete standards are not capable of making full use of the current technology capacity due to strong focus on conventional concrete and thus they are not fit for the current and future challenges of construction industry. The paper highlights shortcomings with regard to the implementation of the existing standards. It can be seen that future-oriented standards are generally required to contribute to a lower-carbon footprint of the industry. These changes are significantly more relevant in sub-Saharan Africa, due to the rapidly increasing urbanisation challenge and the enormous potentials to develop lower-carbon technologies than elsewhere in the world.

Published: April 2023

During an archaeology of garbage project in the city of Tehran in 2018, a garbage bag was documented that presented objects signifying pain and illness. The study of this material evidence indicated that the garbage was from a patient who was hospitalized at home, but a written document also present in the same garbage bag provided further context that led us to revise our initial interpretation. The document showed that these objects were linked not just to a disabled person, but to a victim of the Iran–Iraq War. The violence of war thus extends through time and affects all aspects of everyday life, changing its victims forever. The evidence for this includes waste and garbage. In this paper, we attempt to narrate the story of the pain and suffering of a war victim based on his garbage, a man whose life has been changed forever by war.

ABSTRACT: The objective of this research was to estimate genetic parameters and genetic trends (GT) for 305-day milk yield (MY305) and 305-day fat yield (FY305) of purebred Dairy Gir animals of the National Dairy Gir Breeding Program. The restricted maximum likelihood method was used in an animal model. GT were obtained via linear regression and divided into two periods (1935-1992 and 1993-2013 for PL305; 1935-1992 and 1993-2010 for MY305). The estimated heritabilities were 0.23 (MY305) and 0.10 (FY305). The GT (kg/year) values for MY305 in the 2nd period for measured females (25.49), females (26.11), and males (35.13) were higher than those found in the 1st period (2.52; 2.06, and 1.00, respectively). The heritability estimated for MY305 confirmed the possibility of genetic improvement by selection and indicated a lower additive genetic effect on FY305 of purebred animals. The genetic progress for MY305 in all purebred population is denoted by the more expressive gains found from 1990’s, when the first bull catalogs were published.

Authors: Lakhani Amit , Khatri Kavin , Malhotra Neeraj , Banga R.K , Bansal Deepak
Published: April 2023

ABSTRACT Introduction: Good wound closure is an important step in management of distal femur fracture to prevent infection and faster rehabilitation. Knotless barbed sutures can save time and distribute wound tension evenly. However, its role in terms of functional outcome, closure time, and postoperative complications has not been studied in a distal femur fracture. Material and methods: A total of 47 patients aged more than 18 years of distal femur fracture treated with distal femur locking plate were randomized either into either barbed or traditional suture groups. in the barbed group, capsular wound closure was carried out with 2-0 bidirectional barbed knotless sutures (Quill SRS® PDO, Angiotech, Vancouver, BC, Canada). In patients assigned to group B, capsular closure was done with 1-0 Vicryl® (Ethicon inc. Somerville, NJ) and 5-0 Ethibond® alternatively. Results: The mean flexion at the knee joint was 105.7±15.6 degrees in the study group while it was 110.4±13.7 in the control group (p= 0.2133). Mean estimated closure time was significantly shorter in the study group as compared to the control group (p<0.05). Cases of needle prick injury were higher in traditional suture group. Patients developed stitch abscess and superficial infection in both groups. However, the difference in incidence between the two was not statistically significant Conclusion: Barbed suture is an efficient method of wound closure. It reduces wound closure time with similar complication rate as with use of conventional sutures. Evidence Level II; Randomized Clinical Trial.

Published: April 2023

ABSTRACT Objectives: We aimed to compare the functional and radiographical outcomes of reconstruction of acute unstable acromioclavicular joint (ACJ) dislocation using Hook Plate (HP) versus Suture Endobutton (SE) fixation techniques. Methods: Forty-six consecutive patients with grade III to V ACJ dislocation according to Rockwood classification who underwent either HP or SE fixation in the period between January 2017 and June 2020 were evaluated. The treatment modalities were divided into either HP or SE fixation. The radiological assessment included standard anterior-posterior (AP) views to evaluate coracoclavicular (CC) distances for vertical reduction. Results: CC distances were grouped as preoperative (CC1), early postoperative (CC2), and late postoperative (CC3). The distance variance between CC2 and CC3 was referred as ΔCC (CC3 - CC2). A statistically significant difference was found in ΔCC between the two groups (p=0.008). ΔCC was significantly higher in the SE group compared to the HP group (p<0.05). The Constant and UCLA Scores of patients in the SE group were found to be significantly higher than in the HP group patients. Conclusion: Clinical outcomes were more satisfactory in patients with acute unstable ACJ dislocation who underwent SE compared to HP procedures, at the end of the first year.

Published: April 2023

ABSTRACT Objectives: To present the functional outcomes, through the first case series in our country, of patients with thoracolumbar burst fractures (A3,A4), submitted to short posterior fixation, without arthrodesis and without removal of the implants, until the end of the minimum follow-up of one year. Methods: Fifty five patients consecutively treated between January/2010 and January/2019 were evaluated through medical records and imaging exams. Radiographic analysis was performed by mea suring local and segmental kyphosis using the Cobb method. Functional assessment was analyzed using the non-specific SF-36 questionnaire and the 1983 Denis pain and work-specific questionnaire, applied after 12 months of follow-up. Results: With a loss of five patients (9%), 22 (44%) patients reported having minimal and occasional pain and 8 (16%) patients reported having no pain. Three (6%) patients responded that they were completely incapacitated. Patients had a mean score of 73.16 points in the SF-36 domains. There was a significant reduction in kyphosis in 12 months (9.1±5.2 [min-max 0-22]) compared to the preoperative period (14.9±7.8 [min-max 0-32]) ( p≤0.01). One patient required implant removal due to the symptomatic prominence of the implant. Conclusion: This case series suggests that the technique leads to satisfactory functional results, without implant failure or significant kyphosis after a minimum follow-up of 12 months of treatment. Evidence Level IV; Case series.

Published: April 2023

ABSTRACT Objectives: Investigate the effect of closed reduction and per- cutaneous pedicle screw fixation in treating thoracolumbar fractures. Methods: This retrospective study analyzed 12 cases of single-segment thoracolumbar spine fractures without spinal cord and nerve injury at our department from March 2016 to September 2017. Patients were treated with closed reduction, percutaneous reduction, and internal fixation with solid pedicle screws. The operation time, intraoperative blood loss, anterior vertebral body height ratio (AVHR), Cobb angle (CA) of sagittal kyphosis, and VAS of back pain were determined and statistically compared. Results: The average operation time was 147.2 ± 45.6 min, and the average intraoperative bleeding was 67.8 ± 34.2 mL. All fractured vertebrae were completely reduced, their height was restored, and kyphosis was corrected. The average follow-up period was 10.6 ± 2.7 months, with significant improvements seen in the AVHR, CA of sagittal kyphosis, and VAS score (P < 0.01). One case had a broken rod after three months, and another had a postoperative infection. All the patients achieved bony healing. Conclusion: The treatment of thoracolumbar fractures by closed reduction and internal fixation with a percutaneous solid pedicle screw is simple, effective, and economical.

ABSTRACT Introduction: Ballroom dancing has become popular as an exercise method that encompasses many benefits in the social aspect. However, some middle-aged and elderly dancers have suffered from injuries and other problems from dancing. The comprehensive understanding of gymnastic training to solve this problem has not yet been raised, without which no adequate means of prevention can be outlined. Objective: Study the effect of balanced aerobic training on the physical fitness of middle-aged and elderly ballroom dance practitioners. Methods: A study was conducted with 50 volunteers practicing ballroom dancing, middle-aged and elderly, divided into experimental and control groups. According to the community square dance protocol, the control group performed the dance for one hour daily. The experimental group also used the same period and technique, introducing balanced aerobic exercises. Fitness and performance data were collected before and after the intervention, analyzed, and presented statistically. Results: In the experimental group, the growth rate of the grip strength index was 28.70%, the lumbar strength index was 32.27%, the time rate in the orthostatic position was 6.28%, and the sitting forward flexion index was 6.69%. Conclusion: Compared to traditional community sports, balanced aerobics inserted into ballroom dance training showed an improvement effect on the physical and sports fitness of middle-aged and elderly women, and may also prevent the adverse effects of aging on activities of daily living, and its implementation is valid.

Abstract A one year feeding trial was conducted on carps i.e. Catla (Cattla cattla), Mrigal (Cirhinus mrigala) and Rohu (Labeo rohita) to find out appropriate level of fishmeal in diet and their effects on growth, survival and biomass in intensive polyculture. Three different inclusions of fishmeal were used in experimental diets (25%, 35% and 45%). Highest average daily growth was observed by 25% fish meal diet (2.18g, 2.19g and 2.34g for catla, rohu and mrigal respectively), whereas 35% fish meal based diet was next by showing 1.63g average daily growth for catla, 1.73g for rohu and 1.67g for mrigal. Mean values of monthly weight again and average daily growth showed significant differences among treatments. Growth was found to be higher in C. mrigala in case of 25% and 45% and L. rohita in case of 35% fish meal. Minimum FCR was obtained by 25% FM based diets as 3.53±0.41 followed by 45% (3.82±0.33) and 35% (4.05±0.45). The findings of this research trial determine the optimum dietary level of fishmeal and its effectiveness as an important ingredient in diets of Indian major carps. It is proved that a feed by the combination of animal and plant protein is much preferable by carps as compare to a feed with higher concentration of fish meal.
