Performance Analysis of Partial Shading Effect on PV Plant
Authors: Naing Su Leit , Mon Aye Aye
Published: March 2023

Partial shading of PV plants mitigate the maximum power generation of solar modules. As a result, the power output is lower than expected. It is affected not only by the number of shaded modules but also by the shaded patterns. This paper examined a PV plant rated at 15 kW connected in series-parallel for various shading patterns, such as row-wise and column-wise partial shading. This solar plant's behavior is also investigated under various irradiation levels and degrees of shading. The number of solar modules required for this plant was also evaluated. The performance results of solar modules under partial shading conditions, such as power, voltage, and current, are revealed by using the Matlab/Simulik model. From the analysis, the result shows that the column-wise shading condition generates more power output than the row-wise shading condition.
The Impact Of The Telecommunication Industry As A Moderator on Poverty Alleviation and Educational Programmes To Achieve Sustainable Development Goals In Developing Countries
Authors: Wickramasinghe S.K.C Ruklani , ABD Razak Kamal
Published: March 2023

The purpose of this study is to investigate the influence of the telecommunications industry's contribution to sustainable development in developing nations. A detailed literature study is conducted for this purpose, and a conceptual framework is offered. To validate the proposed conceptual framework, we conducted multiple case studies involving companies in the telecommunications industry from various countries. These findings improved the suggested conceptual framework produced for this study. However, despite the contributions of the telecommunications industry to the Sustainable Development Goals, no study has been conducted to examine how they have benefited poverty reduction and educational programmes in Sri Lanka. The overall purpose of this research is to investigate the role of multinational telecommunications firms as a moderator in achieving sustainable development goals through poverty and education efforts. This study will use a positivist approach. The researchers' research technique would be deductive since they want to draw conclusions based on the hypotheses produced on the questionnaire as part of the quantitative research procedure. The quantitative approach was employed as the primary data collection method. As part of the preliminary research, the telecommunications industry, and academics with a doctorate degree in socioeconomics were questioned. The preliminary study findings revealed that the telecommunications industry has played a significant role in accomplishing sustainable development goals in many countries, and the current study concentrated on developing nations with a particular focus on Sri Lanka. The major findings of a pilot study indicated that contact between the communications industries is required for linkages and spillovers that may assist nations' sustainable development. Furthermore, our findings indicated that increased contributions to education might help Sri Lanka achieve its poverty eradication and sustainable development goals.
Robustness Study of a Tensile Modulus Prediction Model for Semicrystalline Polymers
Authors: Zarbali Ali , Pinke Balázs , Menyhárd Alfréd
Published: March 2023

This work presents a robustness study of a previously developed empirical model that links Young's modulus to two key parameters of crystalline structure; crystallinity and lamellae thickness. The reliability of this modulus prediction model was tested by using different calorimeters and different polypropylene grades as well. Small samples were fabricated from injection-molded bars from different locations of the specimens in order to check the effect of structural inhomogeneity originated by the dynamic processing conditions. In addition, the standard deviation and consequently the accuracy of the prediction was tested by repeated calorimetric measurements. The crystalline structure and melting characteristics were measured by differential scanning calorimetry (DSC). The tensile properties of studied specimens were evaluated by standardized tensile tests. Although, the accuracy and reliability of the prediction model is dependent on the instrument used for thermal analysis, reasonably good agreement was found between the predicted and measured values in most cases. However, we may note that only well-calibrated calorimeters are suitable for reliable prediction of the modulus.
Adaptive and Efficient Hybrid In-loop Filter Based on Enhanced Generative Adversarial Networks with Sample Adaptive Offset Filter for HEVC/H-265
Authors: Moji Vanishree , Murugavelu Mathivanan
Published: March 2023

In this manuscript, an Adaptive and Efficient Hybrid In-loop Filter based on Enhanced Generative Adversarial Network Deblocking Filter (EGANDF) with Sample Adaptive Offset filter (EGANDF-SAO-HEVC) is proposed for High Efficiency Video Coding (HEVC)/H-265. In this, the proposed hybrid in-loop filter involves EGANDF and Sample Adaptive Offset (SAO) filter that lessens the blocking artifacts caused by block-wise processing for coding unit (CU), which is mainly used for improving the video quality. Initially, EGANDF is proposed for HEVC/H-265 for removing blocking artifacts along low computation. Here, the output of EGANDF is given to the SAO filter for reducing ringing artifacts by diminishing high-frequency components during quantization. Thus, the proposed method efficiently reduces artifacts for improving video quality performance. The proposed EGANDF-SAO-HEVC method is implemented in the working platform of HEVC reference software with MATLAB. Finally, the proposed EGANDF-SAO-HEVC model has attained 27.26%, 29.65%, 12.45% higher accuracy, 33.56%, 31.8%, 28.7% higher sensitivity, 34.7%, 33.5%, 32.6% higher specificity, 46.92%, 35.7%, 41.3% lower MSE, 25.7%, 29.7%, 35.6% higher PSNR, and 25.6%, 28.9%, 13.6% higher SSIM for using basketball video sequence when compared to the existing methods.
Ethical considerations in solving economic problems
Authors: Komorowski Jan
Published: March 2023

The article addresses the issue of ethics in business. The positive attitude to ethics declared by some liberal economists confronts business units with new dilemmas. The economic conflicts, wars, and pandemic crisis treated as a challenge for economic recovery highlight the ethical side of choices. In this way, individualistic rationality is confronted with multilateral benefits. The relation between ethical norms and economic criteria considers the point of view respecting human participation in the process of managing a business. As a consequence, ignorance of ethics in business as a concept of applied ethics, which means ethical relativism, leads man to a crisis of values depriving the system of the liberal economy of a sense of orientation and thus hindering the search for rational solutions.Ethics introduces a personalistic dimension to economic considerations associated with an individual responsibility coming from respect for human values and dignity. In the social aspect, compliance with ethics is acondition of mutual acceptance, cooperation, and bonding within the community. Ultimately, the place of ethics in economics is a consequence of the relationship of economics with humans and, at the same time, the attitude of individuals to ethics. Paying more attention to ethical issues serves the humanisation of economic relations, displaces business egotism, and awakens the tendency to cooperate by seeking the common good.
The consumer in the process of deciding on a bank and the Swiss franc as a loan currency: the impact of the decision on consumers’ disposable income
Authors: Słupińska Kamila , Pyzia Patryk
Published: March 2023

At the beginning of the article the authors referred to the consumer, the factors affecting his or her choices and the decision-making process. Subsequently, the factors and circumstances determining the consumer’s choice of a loan denominated in the Swiss franc (CHF) in Poland were specified. In the following section there wa presented an analysis of the value of granted CHF loans in the period from 07.2008 to 05.2022. It was assumed that the analysed group regards: a family of 2+2, i.e., two working individuals with incomes equal to 150% of a minimum wage; a loan of PLN 250,000 to be repaid over 30 years, disbursed on 1.08.2008 in one tranche, being repaid since 1.09.2008. A comparative analysis entailed three selected banks. In the summary, the authors referred to the main hypothesis: despite the knowledge of the economic conditions, the consumer possesses a lower disposable income when choosing a CHF credit, and two auxiliary hypotheses: hypothesis 1 was that home loans denominated in CHF, despite having a lower interest rate are less favourable to the borrower in the long run than the loans denominated in the Polish zloty, and hypothesis 2 was that in the process of deciding upon a bank, the consumer is guided by economic factors.

Published: March 2023

The diagnosis of myelodysplastic syndromes (MDS) might be challenging and relies on the convergence of cytological, cytogenetic, and molecular arguments. Multiparametric flow cytometry (MFC) helps diagnose MDS, especially when other features are non-contributory, but remains underestimated mostly due to a lack of standardization of cytometers. We present here an innovative model integrating artificial intelligence (AI) with MFC to improve the diagnosis and the classification of MDS. We develop a machine learning model by elasticnet algorithm trained on a cohort of 191 patients and only based on flow cytometry parameters selected by Boruta algorithm, to build a simple but reliable prediction score with 5 parameters. Our MDS prediction score assisted by AI greatly improves the sensitivity of Ogata score while keeping an excellent specificity validated on an external cohort of 89 patients with an AUC = 0.935. This model allows the diagnosis of both high and low risk MDS with 91.8% sensitivity and 92.5% specificity. Interestingly, it highlights a progressive evolution of the score from clonal hematopoiesis of indeterminate potential (CHIP) to highrisk MDS, suggesting a linear evolution between these different stages. By significantly decreasing the overall misclassification of 52% for patients with MDS and of 31.3% for those without MDS (p=0.02), our AI-assisted prediction score outperforms the Ogata score and positions itself as a reliable tool to help diagnose myelodysplastic syndromes.

Published: March 2023

This study aims to explore the attitudes of lecturers in online learning in the environment of the South Sumatra Private Islamic Religious University. The research method used is qualitative with a phenomenological approach. The subject of this study is a lecturer who teaches at the South Sumatra Private Islamic Religious College and the chairman of the PTKIS South Sumatra Forum. Data collection techniques through interviews, observation and documentation. Data analysis uses the model formulated by Creswell, first reading the entire data, second doing coding, third applying the coding process, fourth describing the theme to be presented in the qualitative report, and fifth interpreting the data. Based on the results of the study, it was found that online learning has not been accepted as an ideal learning system because it is considered ineffective to be implemented in the environment of the South Sumatra Private Islamic Religious University. This is caused by several factors, namely, 1) inadequate digital infrastructure and financial capabilities, 2) lecturers' technological competence that has not been maximized, 3) A more emphasized factor is the desire to maintain a face-to-face system to maintain an emotional or inner connection between lecturers and students that is considered better than virtual interaction. Islamic education actually has dynamic principles that open up opportunities to adapt to the development of science and technology. Suppose it relates to curriculum, media or learning tools and methods. Then the solution is to use a blended learning model.
A Comparison between Intravitreal Bevacizumab Injection and Placement of a Dexamethasone Implant to Treat Retinal Vein Occlusion Macular Edema
Authors: Kim Hyeong Ju , Min Jung Kee
Published: March 2023

Purpose: We evaluated the macular, functional and structural features of patients with retinal vein occlusion and macular edema. We measured the best-corrected visual acuity (BCVA), central foveal thickness, and the area of the foveal avascular zone area after intravitreal bevacizumab (IVB) treatment and placement of a dexamethasone implant (IVD).Methods: We retrospectively reviewed 36 eyes of 36 patients with retinal vein occlusion and macular edema who underwent IVB treatment (20 eyes) and IVD placement (16 eyes). The parameters mentioned above were compared between the two treatment groups and the normal contralateral eyes after initial stabilization and 1 year later.Results: The BCVA was significantly higher in the IVB than the IVD group after initial stabilization and 1 year later. The intraocular pressure was lower at initial stabilization in the IVB than the IVD group, but no difference was apparent after 1 year. There was no significant between-group difference in the central foveal thickness at any time, but the IVD group required fewer injections during initial stabilization than the IVB group. In terms of the foveal avascular zone area, both the superficial and deep layers of the IVB group increased significantly during the initial stabilization period and then decreased to 1 year; no changes were seen in the IVD group.Conclusions: IVD treatment is associated with fewer injections than IVB treatment and a more stable retinal vasculature, but visual acuity may possibly decrease (because of cataract formation). Although IVB treatment improves visual acuity and reduces macular edema, this may be associated with an increased risk of macular ischemia given the need for repeated injections.

Published: March 2023

The development of alternatives to conventional antibiotics against superbugs represents an important step to avoid the increasing resistance of bacteria observed in conventional treatments. Herein, it was evaluated the influence of different combinations of two active antibacterial components (chitosan and zinc oxide) and a host poly (vinyl alcohol - PVA) in membranes produced by the solvent casting technique. Those systems were evaluated in terms of the biofilm inactivation, kill-time assays and inhibition haloes against S. aureus (ATCC 25923) in membranes that must release reactive components while preserving their integrity and favoring the generation of reactive species to improve the antibacterial activity. The results suggest the potential of the combination of chitosan, zinc oxide and poly (vinyl alcohol) to inhibit the growth of S. aureus colonies since the PVA improved the dispersion of the components, whereas chitosan-ZnO chelate improves the mutual activity of the metal oxide and the natural polymer template.

Published: March 2023

The article aims to consider the formation of global professional competence of students of pedagogical universities, which is the key to the effective professional education of future teachers. In the course of the study, pedagogical conditions are proposed for presenting innovative technologies to form the professional competence of specialists. The level of global dependence is frequently growing, which dictates the need for the training of qualified teaching staff that could effectively solve emerging global problems and take an active position in the society of globalization. In this regard, there is a need to form the global professional competence of students of pedagogical universities, which is the key to effective professional education for prospective teachers. A key element of global professional competence is productive communication, including international communication, which becomes possible by mastering at least one foreign language. Building contacts in a foreign language is one of the global professional competencies and determines success in professional activities after obtaining professional education. Thus, one of the tasks of professional education in training future teachers as part of the formation of competence is the formation and development of the skills required for fruitful intercultural communication, as well as for understanding and accepting representatives of other cultures through transdisciplinary and post-disciplinary approaches.
A Study on the Development of New Silicone based Polymeric Outdoor Insulator Material for Enhanced Properties
Authors: Shanmukha Rao Allu , Sumathi N. , Vasudev N.
Published: March 2023

Polymeric insulators have been increasingly popular in recent years as a result of their superior performance in contaminated environments due to their hydrophobic properties. However, research into the ageing condition of polymeric materials and their practicality for large-scale use is currently ongoing. Insulator deterioration is caused by environmental tracking and erosion factors. As insulators age, they develop immature failures and inconsistencies in their functioning. pollution performance of polymeric insulators is a vital factor in the quality and reliability of the power system. Over some time, dry band arcing can initiate the flashover and it causes degradation in the form of erosion and tracking. Polymeric insulators’ performance is heavily influenced by the constituent materials and their properties. There is a critical need to investigate innovative filler materials that can be combined with existing polymeric base materials to form composites. In this context the proposed research use silicone rubber as a base polymeric material, to which additives are added to produce three distinct composites by varying the filler concentration. Preliminary studies were made to evaluate the hydrophobicity, dielectric strength, hardness, specific gravity, tensile strength, ultimate elongation and tear strength properties of this HTV silicone rubbed-based composites by using ASTM standards and IEC 60587 requirements. Studies were also made by accelerated ageing on sample material by using the IPTE test. The results show substantial improvement in the electrical and ageing properties.

Published: March 2023

Lithium-Ion Batteries (LIBs), which have already proven to be a reliable power source in consumer electronics devices, are being considered a viable option for powering Electric Vehicles (EVs). Fast charging of EVs is one of the key challenges that is preventing a wide range of adoption of EVs. In this study, a lithium-ion cell with Lithium Titanium Oxide (LTO)-lithium Nickel Manganese Cobalt oxide (NMC) chemistry of 30 Ah has been used to study the fast charging capabilities at different temperatures and C-rates. Various parameters such as temperature rise, nominal and exponential capacity, and internal resistance have been studied for different C-rates (C/3, 1C, and 2C) and at different temperatures (25 °C, 40 °C, and -10 °C). The ΔV values along with the charge and discharge characteristics have been analyzed, and the experimental results are compared with the simulation results.
A Study on 500 MW Coal Fired Boiler Unit’s Bowl Mill Performance through Coal Sampling and Characterization: CPRI’s Experience
Authors: Anandakumar M. G. , Venkateswara Rao M.
Published: March 2023

Coal-fired thermal power stations presently account for nearly 52 % of the total power generation in India’s power generation sector. There is a constant need to monitor the performance of the coal-fired power plant auxiliaries/ components and ensure maintenance of these to optimum levels of operating parameters to achieve the trouble-free generation of quality and consistent electric power output. Coal’s mineralogical content and its physical parameters decide the performance of the coal pulverizer in terms of optimum ground coal output and the life of the grinding elements in the coal mills/ pulverizers. The grinding media in the pulverizes are subjected to high erosion rates owing to the presence of abrasive minerals like pyrites, alumino-silicates and hard minerals like α quartz, which are attached to the coal mass as contaminants during mining. A study was undertaken along with the Pulverizers Division of M/s. BHEL for evaluation of Coal Bowl Mill, for guaranteed performance at a 500 MW capacity NTPC thermal power plant. The study was conducted to assess the effective performance of the pulverizers of this 500 MW boiler unit for its maximum capacity of 60.9 t/hr for guaranteed coal condition and assess optimum output in terms of fineness of the crushed coal during continuous loading under the designed operating parameters. The study was also carried out to ensure that the pulverizer grinding efficiency and the effective output of the finely crushed coal were achieved by proper optimization of the mill mechanical auxillaries and their operating parameters.

Authors: Ivanova Elena
Published: March 2023

Field studies were conducted in 2021–2022 at the experimental site of the Sakhalin Research Institute of Agriculture on meadow-sod-gley medium loamy soil according to generally accepted methods. The technology of cultivation of alfalfa is in accordance with the methods of cultivation of perennial herbs developed by the Sakhalin Research Institute of Agriculture. The scheme of the experiment included ten varieties of alfalfa of various ecological and geographical origin. The greatest foliage was demonstrated by plants of the varieties Uralochka, Victoria, Nakhodka in the first mowing and the varieties Uralochka, Vela, Nakhodka, Sarga in the second. The varieties that entered the top three in terms of green mass yield for the period of the first mowing were Taisiya, Sarga and Uralochka varieties. As for the output of the dry mass it was similar. According to the amount of green and dry mass formed in the second mowing the varieties Nakhodka, Taisiya and Sarga were distinguished as the best. On average, for two mowing of the green mass the leading varieties were distributed in such order: the 1st place — the Taisiya variety, the 2nd place — Sarga and Nakhodka, the 3rd third place – Victoria, Agnia VIK and Uralochka. The average yield of the green mass of the Vela variety for two mowing was inferior to the standard Demetra variety by 8%, the yield of the Voronezhskaya 6 variety was at the standard level, the other varieties exceeded the standard by 7.4–21.2%. The average yield of the dry mass for two mowing of the Pavlovskaya 7 variety was slightly inferior to the standard variety, the Vela and Voronezh 6 varieties it was at the standard level, the rest exceeded it by 11.6–35.6%.

Published: March 2023

The results of studies of the quality of grass raw materials for harvesting hay obtained on a long-term hayfield by mowing over the past 5 years (2017–2021) are presented. The quality of herbal raw materials is estimated by the content of crude protein, crude fiber, crude fat, crude ash, the content of metabolic energy in 1 kg of dry matter, feed units, digestible protein in 1 feed unit in accordance with GOST. The quality of feed depends on the prevailing weather conditions during the development of vegetation and the provision of soil with nutrients. In years with unfavorable weather conditions for the development of plants on the option without fertilizers (control), the resulting feed is characterized as extracurricular, under normal conditions – the first and second class of quality. With sufficient provision of the soil with nutrients through the use of mineral fertilizers, the feed in terms of crude protein, fiber and metabolic energy in dry matter belongs to the first class of quality.
EFFECT OF BIOLOGIZED MANURE FROM CHICKENS KEPT IN CAGES ON THE PATHOGENIC MICROFLORA OF SOD-PODZOLIC SOIL
Authors: Schukin Nikolay , Sobolev Dmitriy
Published: March 2023

Sequencing of the metagenomes of soil samples showed that as a result of the introduction of a litter fermented with probiotics by bacteria, the phylogenetic composition of the soil microbiome was preserved, but its taxonomic structure and functionality changed due to an increase in the total number of microbiome bacteria (with different taxon activity). The experiment used a dose of biologized fresh chicken droppings — 120 t/ha, introduced by spreading for plowing, control — without organic matter. In the arable horizon of fertilized soil, an increase in the total abundance of bacteria was noted: in the 1st sampling period — from 6.9 * 107 to 1.3 * 108 copies/g of the soil of the 16S rRNA gene of bacteria, and after 30 days — from 1.6 * 107 to 1.3 * 108 copies/g. In order to ensure the environmental safety of the use of biologized litter for the environment, the presence of pathogenic and conditionally pathogenic microflora in fertilized soil and in the control was investigated, representatives of which were found in all soil samples: a higher proportion of enterobacteria was noted in the control sample (0.6%), and with litter — did not exceed 0.15%; the content of pathogenic bacteria on the fertilized background in the 1st period of soil sampling practically did not change (0.7–0.8%), but in the 2nd it sharply decreased in relation to the control (from 2.5 to 1.1%). Such a decrease in the content of pathogenic bacteria was accompanied by an increase in their numerical abundance (from 3.9 * 105 to 1.4 * 106 copies/g), mainly Pseudomonas sp. bacteria (from 2.1 * 105 to 9.3 * 105 copies/g), which is a consequence of the general increase in the abundance of bacteria in the microbiome against the background of soil enrichment with organic matter and increased soil fertility. At this stage of research, no significant negative microbiological effect of biologized fresh chicken manure on the ecological state of the soil was revealed.

Published: March 2023

The objective of this manuscript was to present the e-Synch system, integrating an intravaginal electronically controlled hormone delivery and sensing device with an IoT platform for remote programming and monitoring. Secondary objectives were to demonstrate system functionality and cow responses to e-Synch. External components of e-Synch include a 3D-printed case with retention wings, a flexible wideband antenna, and silicone membrane for pressure balancing. Internal components include a central control board, battery, wireless charging coil, and two silicone hormone reservoirs connected to individual peristaltic pumps. An accelerometer and a high-accuracy temperature sensor are integrated in the custom printed circuit board (PCB). The IoT platform includes a gateway consisting of Raspberry PI 3 and a CC1352 radiofrequency module that collects sensor data at 915 mHz. Data is transferred to the Google Cloud utilizing the IoT Core service through TCP/IP, and then is pulled by the Pub/Sub service. After routing to a BigQuery table by the Dataflow service, data visualization is provided by Data Studio. Drug delivery protocols are selected using an IOS device app that connects to e-Synch through Bluetooth. Experiments with lactating Holsteins cows were conducted to demonstrate proof-of-concept system functionality and evaluate cow responses. Despite unstable communication and signal discontinuity because of signal strength attenuation by body tissue, devices (n=6) communicated with the IoT platform in 89% (24/27) of use instances. Temperature and accelerometer data were received for at least one 15 min period during an 8 h insertion period from all devices that communicated with the IoT platform. Variation in accelerometer data (± 8.565 m/s2) was consistent with cow activity during experimentation and mean vaginal temperature of 39.1 °C (range 38.6 to 39.5 °C) demonstrated sensor functionality. Hormone release was confirmed in all instances of device use except for one. Cow behavior evaluated through signs of discomfort and pain, and tail raising scores was mostly unaltered by e-Synch. Vaginal integrity and mucus scores also remained unaltered during and after device insertion. In conclusion, the e-Synch device integrated with a controlling app and IoT platform might be used to automate intravaginal hormone delivery and sensing for controlling the estrous cycle of cattle.

The development of composite sections is of great importance in structural design, with the aim of reducing weight and deflection while limiting the effect on the composite section’s strength and durability. This paper examines the computational analysis of composite sections where reinforced concrete was replaced with autoclaved aerated concrete (AAC) in the compression zone. The first principles of concrete combined with Hook’s law were adopted to find a flexure, shear, equivalent modulus of elasticity, effective moment of inertia, and deflection. The results are discussed and investigated using the finite element models developed by ANSYS WORKBENCH software. We found that the proposed analytical model can effectively provide a solution for the composite cross-section. The comparison between the theoretical calculation of the first cracking loads and the finite element percentage ranges from 89 to 110%. The ratio of the computational calculation of the modulus of elasticity to the finite element results ranged from 0.91 to 1.06. The comparison between the theoretical calculation of the effective moment of inertia to the finite element percentage ranged from 92% to 118%. The ratio of the computational calculation deflection to the finite element ranged from 0.87 to 1.15.
