Distribuição Indiscriminada de Recursos, Gerenciamento de Impressão e Voto
Authors: Dos Santos Stephani , Neves Caroline , Fachini Luis Felipe
Published: November 2023

Este artigo discute, sob perspectiva da Escolha Racional, o processo de racionalidade existente no modelo de clientelismo que consiste em distribuição indiscriminada de recursos para gerenciar a impressão que os eleitores têm sobre o candidato, e a eficácia desse modelo em relação ao eleitorado e ao voto. O clientelismo tradicional consiste em uma prática economicamente eficiente de maximização de benefícios, onde os candidatos políticos compram votos de eleitores fiéis, propensos a apoiá-los, ou indecisos. No entanto, Mariana Borges identifica no Sertão da Bahia um modelo distinto, pautado pela distribuição indiscriminada de recursos para o gerenciamento de impressão dos eleitores, mas, não necessariamente, comprar votos. Neste sentido, metodologicamente, este trabalho consiste numa revisão de literatura, amparando-se à um estudo de caso, buscando elucidar o cenário estudado por Borges, a partir das premissas teóricas da Teoria da Escolha Racional. Os resultados sugerem que esse modelo de clientelismo é orientado pela racionalidade, porém, não necessariamente leva o candidato ao resultado esperado, ao considerar que a relação de custo e benefício transcende fatores puramente financeiros, elencando especificidades simbólicas e imateriais que são inerentes às relações sociais, oriundas dos processos políticos eleitorais. Logo, conclui-se que não distribuir recursos indiscriminadamente para gerenciamento de impressões é irracional, ao ponto que, a relação de benefício também se encontra na maximização da imagem do candidato, enquanto um agente político forte para pleitear a disputa institucional.
Constrained incomplete argumentation frameworks: Expressiveness, complexity and enforcement
Authors: Mailly Jean-Guy
Published: November 2023

Operations like belief change or merging have been adapted to the context of abstract argumentation. However, these operations may require to express some uncertainty or some disjunction in the result, which is not representable in classical AFs. For this reason, some of these earlier works require a set of AFs or a set of extensions as the outcome of the operation, somehow to represent a “disjunction” of AFs or extensions. In parallel, the notion of Incomplete AFs (IAFs) has been developed recently. It corresponds to AFs where the existence of some arguments or attacks may be uncertain. Each IAF can be associated with a set of classical AFs called completions, that correspond to different ways of resolving the uncertainty. While these IAFs could be good candidates for a compact representation of a disjunction of AFs, we prove that this model is not expressive enough. Then we introduce Constrained IAFs, that include a propositional formula allowing to select the set of completions used for reasoning. We prove that this model is expressive enough for representing any set of AFs, or any set of extensions. Moreover, we study the complexity of various decision problems related to the verification of extensions and the acceptability of arguments. While some of them are one level higher in the polynomial hierarchy (compared to their counterpart with standard IAFs), most of them have the same complexity than in the case of IAFs. Finally, we show that CIAFs can be used to model a new form of extension enforcement, where the possible evolutions of an AF are taken into account and modeled by the completions of the CIAF.

Published: November 2023

Over the last fifty years, societies across the world have experienced multiple periods of energy insufficiency with the most recent one being the 2022 global energy crisis. In addition, the electric power industry has been experiencing a steady increase in electricity consumption since the second industrial revolution because of the widespread usage of electrical appliances and devices. Newer devices are equipped with sensors and actuators, they can collect a large amount of data that could help in power management. However, current energy management approaches are mostly applied to limited types of devices in specific domains and are difficult to implement in other scenarios. They fail when it comes to their level of autonomy, flexibility, and genericity. To address these shortcomings, we present, in this paper, an automated energy management approach for connected environments based on generating power estimation models, representing a formal description of energy-related knowledge, and using reinforcement learning (RL) techniques to accomplish energy-efficient actions. The architecture of this approach is based on three main components: power estimation models, knowledge base, and intelligence module. Furthermore, we develop algorithms that exploit knowledge from both the power estimator and the ontology, to generate the corresponding RL agent and environment. We also present different reward functions based on user preferences and power consumption. We illustrate our proposal in the smart home domain. An implementation of the approach is developed and two validation experiments are conducted. Both case studies are deployed in the context of smart homes: (a) a living room with a variety of devices and (b) a smart home with a heating system. The obtained results show that our approach performs well given the low convergence period, the high level of user preferences satisfaction, and the significant decrease in energy consumption.

Published: November 2023

Background: Recent genetic research identified a protective factor against late-onset Alzheimer’s disease (AD) in Caucasians, a variant called rs3747742-C in the TREML2 gene. However, the roles of other TREML2 variants in AD have not been fully explored. Objective: We conducted a focused analysis of 16 TREML2 variants, examining their connection to AD by studying their correlation with cerebrospinal fluid (CSF) proteins, neuroimage, and cognition in the Alzheimer’s Disease Neuroimaging Initiative database (ADNI). Methods: A multiple linear regression model was utilized to estimate potential associations between TREML2 genotypes and various endophenotypes in the entire ADNI sample at baseline, with age, gender, years of education, and APOE ɛ4 status included as covariates. To examine changes in clinical outcomes over time, linear mixed-effects models were employed. Results: We found that the SNP rs17328707-A was associated with higher ADNI-VS scores, smaller ventricles, and larger middle temporal volume at baseline. The SNP rs6915083-G was linked to lower CSF t-tau and p-tau levels, and higher CSF Aβ levels. The SNP rs9394766-G was associated with a smaller hippocampus and larger ventricles at baseline. In longitudinal cohorts, the rs6915083-G SNP was associated with changes in ADNI-MEM and ADNI-EF scores, as well as the rate of hippocampal and middle temporal atrophy. Conclusion: Our findings reveal that TREML2 gene variants have different effects on AD. Two variants are protective, while one may be a risk factor. This enhances our understanding of AD genetics and could guide future research and personalized treatments.
Prioritization of types of wireless sensor networks by applying decision-making technique based on bipolar complex fuzzy linguistic heronian mean operators
Authors: Rehman Ubaid ur , Mahmood Tahir
Published: November 2023

Wireless sensor networks are flexible monitoring systems that save track of, data, and communicate multipoint digital information interpretations to other devices. Wireless sensor networks meaningly enhance the accuracy, breadth, and extent of local data collection, commonly doing away with the requirement for expensive data wiring and recurring manual checks at risky, remote, or inaccessible locations. As a result, it is utilized to keep an eye on systems and environmental or physical parameters. In this manuscript, we expand the Heronian mean operators in the model of bipolar complex fuzzy linguistic set to concoct bipolar complex fuzzy linguistic arithmetic Heronian mean, bipolar complex fuzzy linguistic weighted arithmetic Heronian mean, bipolar complex fuzzy linguistic geometric Heronian mean and bipolar complex fuzzy linguistic weighted geometric Heronian mean operators. We also inspect the special cases of the invented bipolar complex fuzzy linguistic arithmetic Heronian mean and bipolar complex fuzzy linguistic geometric Heronian mean operators. Moreover, in this manuscript, we concoct a technique of decision-making in the model of a bipolar complex fuzzy linguistic set with the assistance of the invented operators. As the selection and prioritization of the various types of Wireless sensor networks is the decision-making dilemma, we prioritize various types of Wireless sensor networks by employing the concocted technique of decision-making and by taking artificial data in the model of the bipolar complex fuzzy linguistic set. To reveal the influence and excellence of the concocted work, a comparative study is given in this manuscript.
Іncreasing the efficiency of the use of natural gas in household gas stoves
Authors: Konovalіuk V. , Franchuk Yu.
Published: November 2023

In Ukraine, about a third of the energy is obtained from burning gas (about 30 billion cubic meters of natural gas per year). More than half of this amount of gas is burned in the communal household sector, which includes the population. The largest number of devices intended for burning gas are installed in the population and are household gas stoves used for cooking. The total consumption of gas used by these devices makes up the main part of the gas used in the country in the summer period of the year. In connection with the significant increase in the price of energy carriers and the transition to paying for gas in units of energy, the issue of energy-efficient gas consumption is becoming more and more relevant. In this work, an analysis of the study of the use of gas at different pressures in domestic gas stoves is carried out. A comparison of the efficiency of gas use compared to the use of electrical energy is made. It has been determined that the optimal pressure in front of the gas stove burner, at which combustion has the most economical effect, is 2400 Pa. At this pressure, compared to electrical energy, efficiency increases by 20.8%. When the gas pressure deviates from 2400 Pa, there is a decrease in combustion efficiency, and at a pressure of 1800, the use of natural gas becomes economically impractical (compared to the use of electrical energy for cooking). Combustion of gas, ensuring the necessary completeness of combustion, has a positive effect on the environment as a result of reducing the content of carbon monoxide both in the indoor air of kitchens and in the environment of populated areas. Increasing the energy efficiency of burning natural gas will lead to a decrease in its consumed amount, and as a result, will positively affect the amount of payment for consumed gas, reduce the need for it and increase the level of energy independence of the state.
Features of exploitation of engineering systems of buildings during martial law
Authors: Franchuk Yu. , Konovalіuk V.
Published: November 2023

The destruction of engineering systems of buildings and structures, periodic peak loads in the mode of their work, which are formed during hostilities, significantly affect the stability of the operation of these systems. The need to perform repair and debugging work in the emergency mode is not always consistent with the current labor protection requirements, which were developed for the conditions of operation of engineering networks in peacetime. Given the existing and delayed impact of damage to the operation of engineering systems, it is necessary to take into account the existing conditions in the normative documents, which can be used in the future in major circumstances. Explosions near gas pipelines generate dynamic vibrations similar to pile driving during construction. In this case, the "Safety Rules for Gas Supply Systems" require inspection of welded joints along the entire length of the damage plus 20 m. Often, damage to a gas pipeline caused by an explosion leads to its displacement vertically and horizontally. Therefore, it becomes necessary to check the welded joints closest to the place of damage by a physical control method. If a defect is detected in the joints, it is necessary to check the next joint of the gas pipeline. In addition to through damage, there is a possibility of damage to only the insulating layer. Since it is physically impossible to check an underground gas pipeline, it is necessary to use an instrumental method to detect such damage. Not eliminated insulation damage will lead to intensive corrosion of the steel gas pipeline, and subsequently to the gas leakage. Therefore, it is necessary to conduct an extraordinary instrumental examination, on the basis of which areas that need additional isolation are determined. An inspection and additional sealing of engineering inputs and outputs of underground utilities should be carried out. The buildings should be monitored for the presence of micro-concentrations of carbon monoxide and control of pre-explosion concentrations of methane.

Published: November 2023

At present, the volume of world energy consumption is continuously and rapidly increasing, which is a consequence of the industrialization process, population growth, increase in energy costs for the extraction of natural resources, etc. Therefore, the importance of solving the problem of energy efficiency is of paramount importance for modern civilization. In this work, there is an analysis of international experience of energy efficient construction. The main directions of energy-efficient development are highlighted. It’s shown that the classical method of heat loss calculations wrongly takes into account the wind effect. The more correct one is required. At the same time, it is worth applying linguistic variables and fuzzy logic, which adequately describe states that are described by verbal statements, and not by numerical values. In conclusion, the most emerging tasks for our Republic are selected: optimal placement of the building on the general plan of the city, incl. maintaining the distance between buildings under the construction and urban-planning regulations; proper heat insulation of the building envelope by the orientation of facades and depending on the climatic parameters of the outside air; air-tightening of building avoiding in- and exfiltration; maximum possible automation of engineering systems up to integration from smart house to smart city level; modernization and optimization of the operation of engineering systems; maximum use of renewable and secondary (such as exhaust air) energy sources; rejection of the classical calculation method of heat loss estimation, which takes into account the effect of wind speed, and to develop a new methodology.
Emotion centered racial coping and child development
Authors:   , Edwards Krista D.
Published: November 2023

Victims of racist incidents can experience a host of negative emotions and how those emotions are processed is an integral part to one's well-being and mental health (Lewis et. al., 2015; Paradies et. al., 2015). Although a general body of emotion processing research has been established regarding general social contexts (Gross, 1998; Gross et al. 2011; Gross 2013), there is little research that explores the differentiation in emotion processing in response to racist experiences, or emotion centered racial coping (Dunbar et al., 2017). The current study explored the impact of emotion centered racial coping on the relationship between racism and anxiety, depression, academic self-competence, and math and reading scores. A sample of adults aged 31- 34 (n = 262), part of a larger longitudinal study, reported on the types of emotion centered racial coping messages they received during their childhood. Self-report data for racism, anxiety, depression, academic self-competence, and math and reading scores were collected at grade 12. Findings suggested that emotion centered racial coping (emotion focused type) was the most widely used compared to emotion suppression and emotion expression. Moreover, emotion centered racial coping (emotion focused type) predicted academic self-competence. Lastly, emotion centered racial coping (emotion focused type) significantly moderated the relationship between racism and depression for girls and the relationships between racism and math scores for boys. Implications for emotion centered racial coping and psychoeducational outcomes in addition to direction for caregivers, mental health practitioners and educators are discussed.

Developing learning and strategic competence in pre-service teachers’ professional oral English communication within reflection and differentiation
Authors: Kalenska Valeriia
Published: November 2023

This article deals with developing learning and strategic competence in professional oral English communication of preservice teachers. It highlights the need for seeking new teaching approaches due to recent changes in university curriculum, i.e., the decrease in class hours and the increase in self-study hours. The research analyses the specifics of implementing modern approaches and proves their effectiveness. The paper introduces the definition of learning and strategic competence in professional oral communication of pre-service English teachers, which defines the speakers’ ability to learn consciously and manage their speaking activity in professional situations both effectively and autonomously. Moreover, this case study examines and explains the relevance of reflection and differentiation. It shows that reflective approach enables students to analyse and manage their learning process while mastering learning and communicative strategies, identify the most efficient ones, plan further actions in order to improve earlier developed skills. This paper stresses the necessity of mastering chosen reflection skills by implementing five sequential stages of the reflection mechanism. However, differentiation gives teachers the opportunity to individualise the learning process, varying teaching methods and tools, adapting exercises and activities to students’ cognitive learning styles, peculiarities and needs. Therefore, it suggests combining differentiation with individualization while applying their most relevant aspects. In terms of differentiation the investigation describes mechanisms of adaptation, regulation and improvement, and provides the evidence for importance of individual, pair and group work.

Published: November 2023

The article deals with the peculiarities of the educational technology of mind mapping, reviews several digital applications for creating mind maps, and practically proves the effectiveness of using mind mapping in foreign language classes.The digitization of the educational process, the globalization of knowledge and the availability of educational information arrays, in combination with quarantine restrictions and the war in Ukraine, have presented significant obstacles to foreign language teachers. Although mind mapping technology is relatively new, it has many supporters among linguists. The essence of educational technology based on compliance with the radial type of brain perception of an array of information, which is more natural than linear, is analysed in detail in the article. The appropriate systematicity, structure, simplicity and adaptability of this method of material demonstration, in contrast to the traditional ones, were delivered through the characterization of the main elements of the mental map structure and the basic rules for its creation. The paper provides an overview of three primary online mind map constructors (Gitmind, Mindomo, and Coggle) according to several requirements, adequate for teaching foreign language grammar to first-year students majoring in “Philology”. Based on the review of the basic and target characteristics of mind map applications, the article’s authors recommended the Gitmind constructor and justified the choice. An example of the practical application of mental maps and the application in foreign language classes was also presented in the article. The stages of creating a teaching mind map for presenting a grammar topic were described. The article presents the results of the final survey of students involved in learning with the help of mind maps, which proved the expediency and effectiveness of using mind maps in teaching foreign languages in general, and the optimality of using a digital mind map constructor in particular.

Published: November 2023

Modern technology has had a transformative impact on educational systems, learning, and teaching practices. The advent of the internet and the development of various digital tools have opened up new opportunities for education. Unfortunately, teachers and scholars, who may have educated themselves or being educated in a whole different era and time of schooling, find it really difficult to teach in the new modern ways. Different sides often blame each other for not being ready to innovations: the public blames teachers and superintendents for not adopting new technology in school and in turn teachers blame the state itself for not providing enough money and time. The authors claim that steps must be taken to implement IT in schools, and list possible steps.

Authors: Wang Dandan
Published: November 2023

Objective: This study aimed to explore the impact of nursing interventions on treatment compliance in children with congenital ptosis after surgery. Methods: From April 2021 to April 2022, 82 cases of children who underwent surgery for congenital ptosis at our hospital were divided into an observation group (n = 41) and a control group (n = 41). Both groups received treatment at our hospital and were subjected to different nursing methods post-treatment, with the control group receiving routine nursing interventions and the observation group receiving comprehensive nursing interventions. The treatment compliance, postoperative complications, nursing satisfaction, and quality of life were analyzed and compared between the two groups. Results: The treatment compliance rate was higher in the observation group than in the control group (P < 0.05). The total incidence of complications in the control group was higher than that in the observation group (P < 0.05). Nursing satisfaction was higher in the observation group than in the control group (P < 0.05). After nursing interventions, the quality of life score in the control group was lower than that in the observation group (P < 0.05). Conclusion: Applying comprehensive nursing interventions to children with congenital ptosis after surgery can reduce the incidence of complications, improve treatment compliance, and enhance their quality of life. This approach is worthy of promotion.

Diabetes adalah penyakit kronis yang ditandai dengan tingginya kadar gula darah. Tanpa perhatian dan penanganan yang tepat, diabetes dapat menjadi penyakit yang mematikan. Diperkirakan oleh International Diabetes Federation, pada tahun 2045 nanti penderita diabetes di Indonesia akan mencapai angka 28,6 juta. Monitoring kadar gula darah rutin setiap hari dapat membantu penderita diabetes untuk terus memantau kadar gula darah agar tetap berada di dalam batas normal. Umumnya pengecekan gula darah ini harus dilalui dengan rasa yang kurang nyaman bahkan menyakitkan karena diperlukannya sampel darah. Proses pengambilan sampel darah tersebut dikenal sebagai cara invasive, yaitu dengan menusuk ujung jari dengan lanset agar darah keluar, kemudian setetes darah tersebut diletakan pada strip tes dan hasilnya akan keluar pada meteran glukosa. Untuk memudahkan pemantauan kadar gula darah, pada penelitian ini telah dikembangkan alat non-invasive yang dapat membantu penderita diabetes dalam mengontrol kadar gula darahnya. Dengan memanfaatkan metode Near-Infrared Spectroscopy, pengecekan akan dilalui dengan lebih nyaman, tanpa rasa sakit dan lebih terjangkau. Alat yang dibangun dengan pemanfaatan Flame Detection Module dan ESP32 ini telah berfungsi dengan persentase error dalam pengujian yang dilakukan kepada 5 orang relawan sebesar 17,9%. Output yang dihasilkan dari pengukuran kadar gula darah akan dikirimkan ke aplikasi Telegram beserta dengan tanggal pengukurannya, sehingga data tersebut dapat dijadikan sebagai catatan monitoring harian.

У роботі розглянута можливість автоматизації одного з ключових елементів технологічного процесу виготовлення листових товстостінних деталей із рифтами методом штамповки, а саме транспортування й позиціонування заготовки. Автоматизація процесу виготовлення товстолистових деталей, у тому числі й одержуваних за допомогою процесів вільного формоутворення, з конструкційних і спеціальних сталей є актуальним завданням сучасного машинобудування. Склад і послідовність основних операцій узагальненого технологічного процесу автоматизованого виготовлення таких деталей є відомими, можуть мати декілька класичних рішень, але очевидно, що ключовим моментом є етап виготовлення деталі із заготовки, оскільки можливість його автоматизації та керування ним у реальному часі є вирішальною ланкою системи автоматизації всього процесу загалом. Таке бачення щодо вирішення зазначеного питання та його подальше дослідження й моделювання в умовах наявного обладнання реальних вітчизняних виробництв, що залишилися тепер у робочому стані, дало можливість побудови пропонованої структури автоматизованої системи позиціонування заготовки. Запропонована структура системи автоматизованого переміщення й позиціонування заготовки та виготовленої деталі на всіх етапах технологічного процесу її виготовлення, який базується на застосуванні рольгангу без приводу. Розроблена функціональна схема й алгоритм роботи авторизованої системи транспортування та позиціонування заготовки, проведено її моделювання в середовищі Labview. Результати моделювання виявили можливість реалізації процесу за допомогою гравітаційного рольгангу без приводу з рушієм, який здійснює переміщення заготовки. Створений віртуальний прилад для моделювання процесу переміщення об’єкту вздовж робочого поля з контролюванням його положення за допомогою дискретних датчиків, довів можливість підібрати раціональні величини заданих швидкостей на різних ділянках для усунення небажаних перехідних процесів і мінімізації часу доставки об’єкта до заданої ділянки робочого поля.
On the importance of modeling the invisible world of underlying effect sizes
Authors: Wilson Brent M. , Wixted John T.
Published: November 2023

The headline findings from the Open Science Collaboration (2015)―namely, that 36% of original experiments replicated at p < .05, with the overall replication effect sizes being half as large as the original effects―cannot be meaningfully interpreted without a formal model. A simple model-based approach might ask: what would the state of original science be and what would replication results show if original experiments tested true effects half the time (prior odds = 1), true effects had a medium effect size (Cohen’s δ = 0.50), and power to detect true effects was 50%? Assuming no questionable research practices, 91% of p < .05 findings in the original literature would be true positives. However, only 58% of original p < .05 findings would be expected to replicate using the Open Science Collaboration approach, and the replication effects overall would be only ~60% as large as the original effects. A minor variant of this model yields an expected replication rate of only 45%, with overall replication effect sizes dropping by half. If the state of original science is as grim as a non-model-based (i.e., intuitive) interpretation of the Open Science Collaboration data suggests, should it be this easy to largely account for those findings using a model in which 91% of statistically significant findings in the original science literature are true positives? Claims that the findings reported by the Open Science Collaboration indicate a replication crisis should not be based solely on intuition but should instead be accompanied by a specific model that supports that interpretation.
Effect of size, shape and scattering factors on electrical resistivity of metallic nanomaterials
Authors: Goyal Monika
Published: November 2023

In the present work, the author focussed on the electrical properties of nanostructures. A qualitative model is extended to obtain the expression of thermal conductivity of nanosolid. Using the Wiedemann-Franz law, electrical conductivity and then expression of electrical resistivity is obtained. The inclusion of scattering term in the calculation of electrical resistivity of nanosolid is essential. Incorporating the effect of surface scattering and grain boundary scattering, electrical resistivity is calculated for varied shapes and sizes of nanosolids. The electrical resistivity of nanomaterials is found to increase with decrease in size. The increment in electrical resistivity is found different for different shapes as surface atoms in nanosolid varies with shape and also with the change in surface roughness parameter and reflection coefficient. The present study explains the combined effect of shape, size and scattering factors on electrical resistivity of nanostructure. The proposed model results are depicted with available experimental results in figures for comparison. The study helps to identify the solids that possess high figure of merit and have plenty of applications in electronic devices.

Quantifying attitudes towards invasive alien species (IAS) is fundamental to understand the extent to which conservation scientists agree and can collaborate in their management. We tested the Pest Management Scale (PMS), originally invented to quantify attitudes towards invasive alien mammals in New Zealand, as a tool to quantify broader attitudes towards IAS among bioinvasion experts in Italy.In autumn 2020 we administered an online questionnaire to a sample of 525 experts, representing almost all people working on biological invasions in Italy, that contained a subset of 7 questions from the PMS. We collected 316 answers, both from conservation practitioners (26.6%) and researchers (73.4%), and we used structural equation modeling to test for the psychometric properties of the scale and compare attitude scores between groups.The PMS showed both a good reliability (Cronbach’s alpha = 0.7), validity (CFI = 0.99, TLI = 0.99, SRMR = 0.03, RMSE = 0.02) and measurement invariance, when comparing researchers and practitioners, as well as when comparing respondents working on different invasive taxa. Both researchers and practitioners, as well as respondents with a different background, and respondents of a different age, had similar attitudes about IAS and their management.Out study shows that the PMS, a simple scale originally conceived to measure attitudes towards invasive alien mammals, could indeed be used to quantify the attitudes of experts towards IAS. Even in countries where the public debate about biological invasions is much more recent than in New Zealand. The PMS scale could potentially be used both for large-scale and long-term research about the attitudes of experts about IAS.

Cattle are essential for the growth and maintenance of a country's economy, but different blood parasites (Haemoparasites) can reduce their production, which causes both direct and indirect financial losses for the livestock industry. The incidence of hemoparasites and risk factors related to them were investigated in cattle butchered at the principal abattoir in Katsina. At the point of slaughter, 500 blood samples were aseptically taken, processed, and checked for hemoparasites by identifying parasites on thin blood smears stained with Giemsa. A prevalence of 8.4% was recorded overall. Anaplasma, Babesia, Microfilaria, and Trypanosoma, four genera of bovine hemoparasites, had prevalence rates of 4.0%, 2.4%, 2.4%, and 0.8%, respectively. The prevalence of hemoparasites was found to be greater in females (8.8%) than in males (7.7%), however there was no statistically significant difference (P 0.05). All breeds evaluated during the study tested positive for haemoparasites; the highest frequency, 16.1%, was found in Adamawa Gudali, followed by Sokoto Gudali (10.3%), White Fulani (7.2), and Red Bororo (6.8%). According to the study's findings, there is no statistically significant difference between breeds in the prevalence of haemoparasites (P 0.05). Young people were more likely to have high prevalence (9.1%) than adults (6.4%) or those who were older (8.7%). The current study has identified the haemoparasite status of cattle put to death at the principal abattoir in Katsina. Consequently, to increase livestock productivity, appropriate preventive and control measures are required.

Mining activities usually alter ecosystems through the disruption of the vegetations and the deposition of potentially toxic elements. This study investigated the soil pollution level and evaluated the phytoremediation potential of some native plant species on a mining site at Kuduku, which is located in Keana local government area of Nasarawa State. Plant samples and associated soils were collected from the mining site and analyzed for the presence of metals such as Pb, Cd, Cr and Mn. The Bioconcentration factor (BCF), Translocation Factor (TF) and Enrichment Factor (EF) were also analyzed. They were generally higher concentration of the heavy metal in most of the plants than in soils which indicates the ability of the plant to tolerate and accumulate these metals. Most of the investigated plants have potentials of been phytostabilizers or phytoextractors. Lead recorded the following plants as  phytostabilizers; Acalypha indica. Copper had the following plants as good phytoextractors; Sida acuta, Fumaria parviflora, Triumfetta rhomboidea, Acalypha indica and Ageratum conyzoides. For Manganese, the phytoextractors includes: Calopogonium mucunoides, Fumaria parviflora, Ageratum conyzoides while phytostablizers includes: Triumfetta rhomboidea and Sida acuta. Most of the investigated plants had an enrichment factor (EF) greater than one which also emphasizes on the extent of metal uptake by the plants. For the majority of the plants investigated, their EF was greater than one except in few cases.

E-learning includes learning methods that use information technology and can be accessed via the internet, making it possible to learn remotely without face-to-face meetings. E-learning functions to implement knowledge management practices, especially in sharing knowledge. Studies on various knowledge-sharing factors influencing the adoption of e-learning in the post-pandemic context are still limited in the existing literature. Therefore, this study has the objective of developing an Expectation Confirmation Model by taking into account the factors of knowledge sharing (communication openness, personal trust, sharing motivation, use of technology, and perceptions of ease of use of technology) to test the viability of using e-learning, especially at Srivijaya University. This study uses the Partial Least Squares Structural Equation Modeling (PLS-SEM) method to test the validity of the developed model. Study data was collected from active students at Sriwijaya University who used or are currently using e-learning in lectures. The results of this study show that knowledge sharing factors, including openness of communication, personal trust, motivation to share, usefulness of technology, and perceived ease of use of technology, are important factors in determining the continued use of e-learning services at Sriwijaya University.
