Published: October 2022

Introduction: AI-based techniques can be used to localize and measure the intracerebral haemorrhage (ICH) in computed tomography (CT). This study aims to develop an automated detection algorithm with higher sensitivity in ICH evaluation in comparison to the conventional method. This indirectly influences the patient’s prognosis by reducing the risk of delay or misdiagnosis.
Methods: Selected 50 CT brain images with primary ICH were used for three different measurement approaches including the conventional Kothari method (Conventional), AI-based method (A.I.), and manually marking by the radiologist, which is the ground truth (G.T.). In the automated system, a convolutional neural network (CNN) is used to localize the ICH, followed by a thresholding technique to segment the ICH, and finally, the measurements are computed. The segmentation performance is measured using Dice similarity coefficient. The automated ICH measurements are compared against the ground truth (A.I. vs G.T.). Concurrently, the ICH measurements calculated using the conventional method are also compared against the ground truth (Conventional vs G.T). The t-test analysis is performed between the sum squared error (SSE) of ICH measurements from the automated-ground truth and the conventional-ground truth.
Results: The mean volumetric Dice similarity coefficient for the automated segmentation algorithm when tested against the ground truth, is 0.859±0.135. The t-test analysis of the SSE between conventional-ground truth (median=5.45, SD=3.96) and automated-ground truth (median=0.73, SD=0.78) achieved p-value < 0.001 (p=5.10E-9).
Conclusion: The automated AI-based algorithm significantly improved the ICH surface area measurement from the CT brain with higher accuracy and efficiency in comparison to the conventional method.
Right Coronary Artery Originating From Mid Left Anterior Descending Artery: A Rare Variant of Anomalous Right Coronary Artery Detected on CT Coronary Angiography.
Authors: Husin Mohd Hafizuddin , Mohamad Jamali Ahmad Aizuddin , A Hamid Mohd Azaad , Saad Khairulanuar
Published: October 2022

Background: A single coronary artery (SCA) is a rare anomaly encountered using conventional coronary angiography. A right coronary artery (RCA) originating from a left anterior descending artery (LAD) is a rare subtype of SCA. Only a few cases are described in published literature.
Case presentation: We described this anomaly in a 55-year-old male who presented with angina pectoris. The anomalous RCA was suspected by conventional coronary angiogram and was confirmed by computed tomography (CT) coronary angiography. Using CT, we demonstrated the course of the abnormal vessel and its relation to the main vessel. We also detected the presence of plaque, which caused luminal stenosis of the proximal LAD, which may cause global ischaemia.
Conclusion: We concluded that although conventional coronary angiography is an important diagnostic method, new non-invasive methods such as CT coronary angiography can be a better screening tool to detect and characterise coronary anomalies.

Тhe article presents data on the prevalence of sucking pests ‒ grape thrips, rose leafhopper, buffalo leafhopper during the growing season of grapevine plants in 2021. In recent years, an increase in the number and harmfulness of sucking pests of thrips and leafhoppers has been noted in the Rostov region, which is due to climate change, the weakening of organiza-tional and economic measures and agricultural practices (an increase in the number of waste lands and the spread of weeds on them). The research was carried out in the conditions of the experimental fields of the "Novocherkassk" and "Nizhenekundryuchensky" departments on the varieties Cvetochniy and Cabernet Severny. So, in the conditions of 2021, two generations of grapevine thrips, three generations of roseate cicadas and one generation of ceres-buffalo ci-cadas developed. In the course of monitoring studies, we found that the most widespread populations in the conditions of the vegetation period of 2021 were: the roseate cicada and the ceres-buffalo cicada, which were identified both in the conditions of the experimental field of the Novocherkassk branch (more South – Novocherkassk) so it is in the conditions of the experimental field of the "Nizh-nekundryuchenkso" department (more northern – Ust-Donetsk district). Planning and organiza-tion of plant protection should be based on the forecast of the phytosanitary state of the agro-cenosis, which is based on the monitoring of harmful sucking pests.

An important direction of the long-term plan for the development of viticulture and wine-making in the Crimea is the production of products with a geographical status. One of the signs that determine the origin of wines is their mineral composition, which depends on soil and climatic conditions and agrotechnical methods of cultivation. The aim of the study was to use the ratios of mass concentrations of potassium, sodium, calcium, magnesium cati-ons to assess the geographical position of wines made from grapevine varieties growing in different regions of the Crimea and Ukraine. A comparative analysis of the ratios of К+/Na+, K+/Ca2+, K+/Mg2+, Ca2+/Mg2+ cati-ons and tartaric acid to the sum of cations was carried out. A significant difference in the mass concentration of the sodium cation and К+/Na+ ratios in these regions has been estab-lished. The ranges of ratio of К+/Na+ cations for some Crimean enterprises have been speci-fied.
Packet-based Adaptive Virtual Channel Configuration for NoC Systems
Authors: Gharan Masoud Oveis , Khan Gul
Published: October 2022

Growing number of on-chip cores requires the introduction of an efficient communication structure such as NoC. In NoC design, the channel buffer organization facilitates the use of Virtual Channels (VC) for on-chip communication. A VC structure can be categorized as static or dynamic. In a dynamic VC structure, variable number of buffer-slots can be employed by each VC according to different traffic conditions in the NoC. We introduce a Packet-Based Virtual Channel (PBVC) scheme, where a VC is reserved when a packet enters the router and released when the packet leaves. A VC will hold the flits of only one packet at a time that subsequently removes the Head-of-Line blocking. PBVC technique is an amended version of dynamically allocated multi-queue schemes where, an input or output port employs a centralized buffer whose slots are dynamically allocated to VCs. The experimental results show that our approach improves network latency and throughput as compared to other VC designs.
Social Simulations Teach Engineering Student to Gain 'Buy-In' for Human Factors
Authors: Neumann Patrick , Rosen Rheta
Published: October 2022

This presentation describes social skill development of undergraduate industrial engineering students using ‘social simulations’ in which students interact with trained actors in a designed social scenario. We present the example scenario of a young engineer who must gain buy in from industrial personnel to apply human factors (HF) in production system design. This experiential learning activity was designed with the Interpersonal Skills Teaching Centre at Ryerson University, in response to research evidence that training engineers in HF science alone is ineffective if the organisational environment and culture do not ‘buy-in’ to available benefits. The simulation is enacted by 3 actor/simulators in 2 scenes. They represent the plant manager, human resources manager, union representative, maintenance manager, purchasing agent, and production supervisor for a small manufacturing plant. Students take turns being engineers from head office who have been sent to help design a new production system for improved performance and reduced injury using HF principles. Students must address the concerns of each of the plant’s stakeholders to gain buy-in for this new approach for production development. This presentation will present and discuss the methodology and evaluation options for this technique for teaching social skills to engineering students.

Introduction: Chronic kidney disease (CKD)-mineral and bone disorder (MBD) is a major complication in hemodialysis (HD) patients. Serum intact parathyroid hormone (iPTH) has been associated with prognosis in these patients, however, the optimal range to reduce mortality remains unknown. Methods: We conducted a retrospective study of incident HD patients, who were categorized into 4 groups according to iPTH serum level: <150 pg/mL, 150-300 pg/mL, 301-600 pg/mL and >600 pg/mL. All-cause and cardiovascular mortality over a mean follow-up of 3 years was assessed using standard survival methods. Results: One hundred and forty-nine patients were included. Patients with low iPTH presented low serum albumin, phosphorus, and bonespecific alkaline phosphatase (BAP), increased c-reactive protein (CRP) and higher serum bicarbonate (p<0.05). Those with iPTH <150 pg/mL had an increased risk of all-cause and cardiovascular mortality, when compared to those with iPTH 301-600 pg/mL (HR: 0.59; 95% CI: 0.36-0.96; p=0.035) and iPTH >600 pg/mL (HR: 0.39; 95% CI: 0.20-0.78; p=0.008), even after adjusting for potential confounding factors as age, albumin, and comorbidities (diabetes, congestive heart failure (CHF), and hypertension). Discussion: PTH levels were associated with all-cause and cardiovascular mortality risk in our cohort of incident HD patients. Our results suggest that patients with low iPTH at HD initiation had an increased mortality risk, which may reflect a frail group of patients with anorexia, sarcopenia, malnutrition, and inflammation.

Published: October 2022

The trend of utilization of low-grade thermal energy gain huge attention due to increase in energy demand and depletion of conventional resources of energy. Low grade energy can be used in ORC-VCR cycle for refrigeration purpose. In the present work, to improve the performance a modified ORC-VCR cycle, recuperator and reheater are integrated in the cycle. The thermodynamic analysis of the modified system has been conducted with R600a, R600, R290 and R1270 as working fluids under various operating conditions viz. evaporator temperature, condenser temperature, boiler exit temperature. Different parameters evaluated to assess the performance are overall COP, mass flow rate per kW cooling capacity, expansion ratio and compression ratio. From the analysis, butane is found as a best choice for the modified ORC–VCR cycle. It was found that for the modified ORC-VCR cycle at boiler exit temperature of 90°C and condenser temperature 40°C has system COP of 0.5542 with butane, which is 7.1% and 18% higher than that of ORC-VCR cycle with recuperator and simple ORC-VCR cycle, respectively.

Published: October 2022

This study x-rays the analysis of convection heat transport of hydromagnetic Forchheimer nanofluid flow in the presence of an ideal internal heat source/sink. A similarity tactic is followed by translating the partial differential models into coupled nonlinear ordinary differential equations. The application of the improved series scheme made it possible for the solution to the translated problems to be found. Pictorial developments such as graphs with legends have been gotten by adopting the Wolfram Mathematica package for the sake of understanding the behavioral pattern of flow, temperature, and specie (nanoparticle) concentrations due to the influence of fluid parameters on them. Results demonstrated that an increase in flow and temperature occurs as buoyancy effect, and optimal heat generation number rises. Intensification of Prandtl number leads to a drop in the flow rate and temperature just as the concentration distribution declines for . The impact of fluid parameters on skin friction was also considered.

Published: October 2022

Phage P2 was isolated from failed fermentation broth carried out by Lactiplantibacillus plantarum IMAU10120. A previous study in our laboratory showed that this phage belonged to the Siphoviridae family. In this study, this phage’s genomic characteristics were analyzed using whole-genome sequencing. It was revealed that phage P2 was 77.9 kb in length and had 39.28% G + C content. Its genome included 96 coding sequences (CDS) and two tRNA genes involved in the function of the structure, DNA replication, packaging, and regulation. Phage P2 had higher host specificity; many tested strains were not infected. Cell wall adsorption experiments showed that the adsorption receptor component of phage P2 might be a part of the cell wall peptidoglycan. This research might enrich the knowledge about genomic information of lactobacillus phages and provide some primary data to establish phage control measures.
Structural and Dynamic Analysis of Leaf-Associated Fungal Community of Walnut Leaves Infected by Leaf Spot Disease Based Illumina High-Throughput Sequencing Technology
Authors: Wang Shiwei , Tan Yu , Li Shujiang , Zhu Tianhui
Published: October 2022

Leaf-associated microbiota is vital in plant-environment interactions and is the basis for micro-ecological regulation. However, there are no studies on the direct differences in microbial community composition between disease-susceptible and healthy walnut leaves. This study collected five samples of healthy and infected leaves (all leaves with abnormal spots were considered diseased leaves) from May to October 2018. Differences in fungal diversity (Chao1 index, Shannon index, and Simpson index) and community structure were observed by sequencing and analyzing diseased and healthy leaf microbial communities by Illumina HiSeq sequencing technology. The main fungal phyla of walnut leaf-associated were Ascomycota, Basidiomycota, and Glomeromycota. Diversity indices (Shannon and Chao1 index values) of healthy leaves differed significantly in the late stages of disease onset. The results showed that the fungal species that differed considerably between the healthy and infected groups differed, and the fungal species that differed significantly between the healthy and infected groups changed with the development of the leaf disease. Critical control time points were determined by analyzing the population dynamics of pathogenic fungi. Leaf-associated microorganisms are abundant and diverse, and fungal identification and diversity studies are helpful for developing more appropriate walnut management strategies

Published: October 2022

This study aims to investigate trends in bloodstream infections and their antimicrobial susceptibility profiles over 12 years in our hospital. This retrospective study was carried out in the Bursa Uludag University Hospital, Turkey, during 2008–2019. Blood cultures from patients were performed using BACTEC System. Isolates were identified with Phoenix System until 2018 and “matrix-assisted laser desorption ionization time-of-flight mass spectrometry” (MALDI-TOF MS) in 2019. Antibiotic susceptibility testing was performed with Phoenix System. Patient data came from the BD EpiCenter™ data management system. Escherichia coli was found to be the most common Gram-negative (11.6%), and coagulase-negative staphylococci were the most common Gram-positive (10.1%) monomicrobial growth. Overall, there was a significant increase in rates of extended-spectrum β-lactamase positive E. coli (p = 0.014) and Klebsiella pneumonia (p < 0.001), carbapenem-resistant E. coli (p < 0.001), and K. pneumoniae (p < 0.001) and colistin-resistant K. pneumoniae (p < 0.001) and Acinetobacter baumannii (p < 0.001) over 12 years. Carbapenem and colistin resistance has increased dramatically in recent years. We believe that regular monitoring of the distribution of pathogens and antibiotic susceptibility profiles, especially in intensive care units, can contribute to evidence for the increase in resistant microorganisms and help prevent their spread with antimicrobial stewardship and infection control policies.

Published: October 2022

Learning science concerning early childhood should focus on a fun learning process. However, children's interest in learning while participating in the science learning process is still low; some children are busy playing alone, disturbing their friends, doing other work, and going in and out for various reasons when science learning occurs. This study aims to increase children's interest in learning science through plant puzzle media. The research used the Classroom Action Research (CAR) with the Kemmis-Taggart model with four stages: plan, implementation, observation, and reflection. The participants are ten children aged 5-6 years at Al Faiz Early Childhood Education (ECE) Langsa, Aceh. The researcher used an observation sheet with four indicators: interest in learning, attention to learning, motivation, and knowledge to obtain improvement data. The results showed an increased children's interest in learning science in each cycle. The average score of children in the Well Developed (WD) category was 76%. In addition, children's activities also showed outstanding improvement during the teaching and learning process. The researcher concluded that plant puzzle media could increase children's interest in learning science. The implication of research related to the effectiveness of plant puzzle media on learning other than science needs to be studied further.

Bibliometamorphioses and Bibliologos in the transient world
Authors: Sokolov A. V.
Published: October 2022

To assess the socio-cultural, scientific and pedagogical novelty and significance of the annual reports of the international forum “Crimea”, read by Ya. L. Shraiberg in 2001–2021, the key words are used – the neologisms “bibliometamorphosis” and “Bibliologos”. Metamorphoses (transformations, transformations) embody the universal variability of the world, and at the same time its stability, since the transforming object does not disappear without a trace, but is transformed into a related entity. Therefore, a book or a library in today's changing world should remain a book and a library, despite external modernization, digitalization and globalization. Bibliometamorphic institutions are religion, ideology, science, art, education, which perform social information and communication functions through book communication (written texts). The bibliologos (literally, “book mind”) performs in a civilized society the function of a productive force that ensures the creation, preservation, and use of the bibliosphere. The bookish mind is realized in two ways: first, the animate Bibliologos in the form of social groups of subjects of the bibliosphere; secondly, the materialized Bibliologos in the form of scientific, educational, normative and administrative texts of intellectuals-scribes devoted to the bookish mind and culture. The animate Bibliologos is the collective mind of library, bibliographic and book professionals (practitioners, scientists, educators), government and commercial figures, bibliophiles, printing engineers, readers' asset directly involved in the production, transformation, preservation and distribution of written and printed works. The technical, political, humanistic metamorphoses of the Logos of modern Russia are considered in detail. The key role of libraries in the socio-cultural metamorphoses of the post-industrial society is shown. The article concludes with a call for continued regular review of library and information science and practice.
Antimicrobial effect of essential oils in content of edible films (review)
Authors: Dyman T.
Published: October 2022

The globalization of food trade, the growing demand for minimally processed, easy-to-prepare, ready-to-eat food, and the proliferation of centralized food processing pose serious problems for food safety. Outbreaks of infectious diseases of alimentary origin stimulate the search for innovative ways to increase the safety and shelf life of ready-to-eat foods. No less important is the problem of solid waste disposal, a significant share of which is food packaging. Therefore, in the last decade, interest in edible films and packaging has increased significantly. Essential oils are natural antibacterial agents that can be successfully used in edible films as a substitute for synthetic compounds. Numerous studies have shown that antimicrobial films and coatings with the inclusion of essential oils are effective in reducing the level of pathogenic microorganisms such as Listeria monocytogenes, Salmonella Typhi, Staphylococcus aureus, Escherichia coli O157: H7 and others. Essential oils have the status of GRAS (Generally Recognized as Safe) registered by the European Commission and the United States. They contain a wide variety of secondary metabolites that are capable of inhibiting or slowing the growth of bacteria, yeasts and moulds. In addition to external application on the surface of food systems, the components of essential oils can diffuse into food to neutralize the target microorganisms. The article summarizes current information on the sources, properties, limitations and potential application of volatile essential oils and their compounds in edible films and packaging to ensure food safety. Despite the many advantages, the inclusion of these compounds in the composition of edible films requires additional research, in particular to determine the optimal inhibitory concentrations, mechanical and functional properties of the films and so on.

Search for longevity predictors for dairy cows
Authors: Khmelnychyi L.
Published: October 2022

The results of researches of domestic and foreign authors were summarized in the aspect of studying the problematic issues concerning the evaluation of dairy cows on the traits of duration economic use and lifetime productivity. The researchers reported that productive longevity traits of cows largely depended on hereditary (conditional bloodliness by the improving breed when crossing, intralinear and interlinear selection, linear breeding, the degree of inbreeding, the strength of influence breeding value of ancestors) and paratypical (age at the first calving, correlative variability between linear traits and longevity) factors.In most cases, an increase the share of heredity due to absorption crossing led to reduction in the duration of productive use and lifetime productivity of cows. When studying population genetic parameters, the authors of many studies confirmed the low level of heritability of longevity traits, which did not contribute to effective selection based on the duration of productive use and lifetime productivity. Analysis of the results of these studies confirmed that linear traits of the conformation type of dairy animals can be used as early indirect predictors of longevity. This conclusion was based on the high heritability of linear traits and existence of positive correlations between them and duration of productive life.

Published: October 2022

In this paper, the sustainability of cattle production in the crossborder region of North-East Romania and the Odessa region, Ukraine was pursued. The working methods used in this research were: observation, information systematization, mathematical-statistical method, and scientific explanation. The average milk production on lactation and on the breeds in Romania varied as follows: Transylvanian Pinzgau breed (PT) – 4118–4724 kg milk, Brună breed (B.) – 3543–5211 kg milk, Bălțată Românească breed (BR) – 2833–5519 Kg milk, and Bățlată cu Negru Românească breed (BNR) – 4.322–6.332 kg milk. Regarding the meat production, in 2016 it was 206 thousand tons live weight at slaughter, which increased by 6 thousand tons compared to 2015 when meat production was 200 thousand tons live weight at slaughter. The average milk production per cow in the Odessa region was 3.577 kg in 2014, down 262.0 kg compared to 2013, and by breed it was as follows: Red Ukrainian- 4.215 kg, Black Ukrainian spotted 4.665 kg, and Red Steppe with 3.394 kg milk. Also, meat production in 2014 was 32.203 kg, and in 2013 – 35.233 kg, with 3.030 kg less or 8.6 %. In the cross-border area of Romania as well as in the cross-border area of Ukraine in the analyzed farms, with large or family-type farms, the allowance of production factors is under necessity, the current conditions, especially financial, allowing only the use of certain production factors (breed, feed). If in Romania, the European funding contributes to achieving the sustainability of cattle production, in Ukraine, farmers face major deficiencies.

Published: October 2022

The state of the microclimate in the light-frame, reconstructed cowshed and milking parlor with a loose-box method of keeping a dairy herd in the spring was studied; the influence of different conditions and parameters of the microclimate on milk quality was investigated. It was found that the temperature in the reconstructed cowshed with forced milking in the hall by the milking machine «Yalynka» averaged 14.27 ± 2.105 ° C, while in the milking parlor the temperature was slightly higher than 16.38 ± 1.335 ° C. In the light frame cowshed the temperature was 12.24 ± 1.380 ° С, and in the milking zone of cows with the robotic installation almost without deviation 12.14 ± 1.715 ° С. Humidity and speed of air movement in the compared rooms was within the hygienic norms. Microbiological indicators of bacterial air pollution in both rooms correspond to hygienic norms, but in the reconstructed cowshed the number of colony-forming units in 1 m3 was higher. The largest number of colony-forming units in 1 m3 was recorded in the air of the milking parlor where the UDE-8 "Yalynka" unit is located due to insufficient ventilation, high humidity and temperature. Dispersion of the tiny drops from the cows udder in the air and other body limbs, equipment and fences when washing the milking parlor with water under pressure. In a light frame cowshed with free milking with a robotic unit at the ALC "Terezyne", the acidity of milk was 16.4 ± 0.64 ° T; the purity degree was according to the standard of the first group, the temperature 30 minutes after milking was 4.2 ± 0.57 ° C; microbial contamination of milk was on average 233.4 ± 8.64 thousand CFU / cm3; the titre of colon bacillus group was about one; the number of somatic cells was 376.9 ± 29 thousand / cm3, which ultimately corresponded to the highest grade according to DSTU 3662: 2018. When milking by the UDE-8 "Yalynka", the acidity of the obtained milk was 18.6 ± 0.42 ° T; the degree of purity according to the standard corresponded to the first group, the temperature 30 minutes after milking was 5.8 ± 0.71 ° C; microbial contamination of milk averaged 292.3 ± 12.3 thousand CFU / cm3; the titre of colon bacillus group was about one; the number of somatic cells was 465.7 ± 19 thousand / cm3, which ultimately corresponded to the first grade according to DSTU 3662: 2018. Therefore, the maintenance of the dairy herd in both light-frame and reconstructed premises allows to form a sufficiently comfortable sanitary and hygienic conditions. The increase in microbial contamination of milk obtained from cows in the milking parlor by UDE- 8 "Yalynka" is the result of insufficient operation of the ventilation system of the milking parlor and improper implementation of certain elements of preparation of animals for milking.

Authors: Muthuramu S , Ragavan T
Published: October 2022

The genotype × environment interaction and stability performance of 15 rice landraces was studied using the additive mean effects and multiplicative interaction (AMMI) analysis. The overall, results indicated that significant genotype × environmental interaction (GEI) influenced the relative ranking of the rice landraces across the years/seasons. It was evident from AMMI analysis that first two principal components accounted for 91.90%, which is enough to explain the variability among the landraces. The landraces, G8 (Kallurundaikar), G4 (Sivapuchithiraikar) and G5 (Kuruvaikalanjiyam) exhibited high grain yield. The AMMI 2biplot revealed that the rice landraces, G12 (Poongar), G14(Kala namak) and G15 (Kichali samba) are close to the origin indicating non sensitive nature of these genotypes with the years/seasons and highly stable genotypes across the environments with low yield potential when compared to others. According to the polygon view of GGE biplot, the genotype G8 (Kallurundaikar) was the winner in the environments E2 and E5 whereas the genotypes G5 (Kuruvaikalanjium) and G7 (Mattaikar) were the winners in the environment E1, E3 and E4. The landrace, G8 (Kallurundaikar), has high mean yield with stable performance over five environments being the overall best and it may be considered for the direct seeded rice cultivation in the rainfed ecosystem.

Authors: Samant TK , Garnayak LM , Paikaray RK
Published: October 2022

Effects of two rice establishment methods namely, direct seeding (DSR) and transplanting (TPR) and three nutrient management practices in rice and three nutrient management practices in groundnut of rice (Oryza sativa L.)- groundnut (Arachis hypogaea L.) system were investigated. TPR produced 7.1 and 5.6% higher grain (5.75 t/ha) and straw (6.81 t/ha) yields than DSR with superior yield attributing characters. INM (green manuring + 50% STBN + 100% P2O5 + 100% K2O) enhanced grain and straw yields of rice by 13.3 and 10.0% over inorganic (100% STBF) and by 15.2 and 8.2% over organic (green manuring + 1/3rd STBN through vermicompost + 1/3rd STBN through neem oil cake) management practices, respectively. INM practice in groundnut (75% STBN + 25% STBN (FYM) + lime 0.2 LR + biofertilizers (Rhizobium + PSB) + 100% P2O5 + 100% K2O) also produced the highest pod (2.74 t/ha) and haulm (3.62 t/ha) yield, which were, respectively, 39.8 and 5.5% higher over 75% STBF and 20.2 and 1.4% more than 100% STBF. But, DSR resulted in higher system yield (12.7 t REY/ha), system productivity (34.7 kg REY/ha/day), energy productivity and accumulated heat use efficiency than TPR system. INM practice in rice showed maximum system yield, productivity and P and K balance whereas, organic approach resulted in higher N balance. INM in groundnut produced the maximum system yield, productivity, HUE and N balance, but 75% STBF showed maximum agro-meteorological indices, P and K balance in spite of lowest system yield and system productivity. Energy productivity and efficiency were higher with 100% STBF in groundnut.

Published: October 2022

MYB gene plays an important role in plant growth, development and response to abiotic stress. In the present study, ‘Yatomi Rosa’ grape (Vitis vinifera L.) was used as the test material. Two MYB, VvMYBB1 and VvMYBA3 gene were obtained by homologous cloning, and their subcellular location, different organs, and expression patterns under stress treatment and hormone induction were obtained. VvMYBB1 and VvMYBA3 proteins were located in the nucleus and belonged to nuclear proteins. They were highly expressed in roots and flowers. These genes might have a negative effect on the formation of peel color. VvMYB1 gene and VvMYBA3 gene might play an important role in drought resistance and salt stress resistance. Under the induction of exogenous hormones, relative expression of VvMYBB1 gene was higher than that of VvMYBA3 gene under IAA, ETH, SA and MeJA treatment. Relative expression of VvMYBB1 gene was lower than that of VvMYBA3 gene under 6-BA, GA3 and ABA treatment. It showed that MYB gene played an important role in the development of different organs of grapes, fruit color, and response to abiotic stress and exogenous hormones induction in grape.

Empirical Analysis of Vulnerabilities in Blockchain-based Smart Contracts
Authors: Khan Dr. Kashif Mehboob , Zahid Ansha
Published: October 2022

With the evolution of technology, blockchain a swiftly impending phenomenon i.e., "decentralized computing” is observed. The emergence of Smart Contracts (SC) has resulted in advancements in the application of blockchain technology. The Ethereum network’s computing capabilities and functionalities are founded on the basis of SC. A smart contract is a self-executing agreement between buyer and seller with the terms of the settlement between them, written directly as lines of code, existing across a distributed decentralized blockchain network. It is a decentralized software that runs on a blockchain autonomously, consistently, and publicly. Conversely, due to the complex semantics of fundamental domain-specific languages and their testability, constructing reliable and secure SC can be extremely difficult. SC might contain some vulnerabilities. Security vulnerabilities can originate from financial tribulations; there are a number of notorious events that specify blockchain SC could comprise numerous code-security vulnerabilities. Security and privacy of blockchain-based SC are very important, we must first identify their vulnerabilities before implementing them widely. Therefore, the purpose of this paper is to conduct a comprehensive experimental evaluation of two current security testing tools: Remix solidity static analysis plugin and Solium which are used for static analysis of SC. We have conducted an empirical analysis of SC for finding tangible and factual evidence, controlled by the scientific approach. The methodology’s first step is to gather all of the Ethereum SC and store them in a repository. The next step is to use the Remix solidity static analysis plugin and Solium to perform vulnerability assessments. The last step is to analyze the result of both tools and evaluate them on the basis of accuracy and effectiveness. The goal of this empirical analysis is to evaluate the two FOSS tools: Remix solidity static analysis plugin and Solium on the basis of accuracy and effectiveness. Some research questions were considered to reach the stated goal: What automated tools and frameworks are proposed in supporting the state-of-the-art empirical approach to SC vulnerability detection? How accurate are security analysis tools? And which tool has more accuracy rate? How effectively security analysis tools are detecting vulnerabilities in SC? And which is the most effective security analysis tool? We investigated the effectiveness and accuracy of security code analysis tools on Ethereum by testing them on a random sample of vulnerable contracts. The results indicate that the tools have significant discrepancies when it comes to certain security characteristics. In terms of effectiveness and accuracy, the Remix plugin outperformed and beat the other tool.

Published: October 2022

Traffic density is growing day by day due to the increasing population and affordable prices of cars. It created a void for traffic management systems to cope with traffic congestion and prioritize ambulances. The consequences can be a terrible situation. Emergency vehicles are the most affected in these situations, and inadequate traffic control can put many lives at stake. Ambulances on the road are detected using an acoustic-based Artificial Intelligence system in this article. Emergency vehicle siren and road noise datasets have been developed for ambulance acoustic monitoring. The dataset is developed along with a deep learning (MLP-based) model and trained to use audio monitoring to predict the ambulance presence on the roads. This model achieved 90% accuracy when trained and validated against a developed dataset of only 300 files. With this validated algorithm, researchers can develop a real-time hardware-based model to detect emergency vehicles and make them arrive at the hospital as soon as possible.
