The paper describes an improved method for estimating the technical effect after correction of electric modes in electric arc furnaces and ladle furnaces. The main indicators of efficiency for these types of equipment are specific power consump-tion and electrode wear. The study shows that after correction of electric modes in electric arc furnaces and ladle furnaces through parameterization of electric mode control system (or implementation of new control system), estimation of these parameters may be inaccurate. This is caused by the inapplicability of direct comparison of specific power consumption and electrode wear over separate time periods, due to the impact of different technological fac-tors. In contrast with existing methodology, the improved method takes into account the impact of technological factors with unequal values over separate time samples. The new method is based on statistical and correlation analysis of electri-cal and technological characteristics for pre-warranty and post-warranty periods. The most unfavourable period for achiev-ing the technical effect is determined on the basis of average values analysis. Further estimation of the technical effect is provided in relation to the most unfavourable conditions. The proposed method may be applied for a more precise assess-ment of the efficiency of electric arc furnaces and ladle furnaces after adaptation of parameters in electric mode control sys-tem or after the replacement of a control system.

Renewable energy resources for electrical generation are normally free but are not continuously available due to their sporadic availability. Thus, hybrid connections of various kinds of energy are made to increase utilization of renew-able energy. This paper involves a design of a hybrid renewable energy system employing maximum power point tracking (MPPT) techniques. The hybrid system consists of solar PV panels, a small-scale wind turbine, and a thermoelec-tric generator (TEG) module. Four MPPT techniques are examined in this research. They are the incremental conductance (IC) algorithm, fuzzy logic controllers (FLC) using 25 and 35 rules, and an interval type 2 fuzzy logic con-troller (IT2FLC). Each MPPT technique is tested in the system to determine which has the best maximum power tracking, stable operation, and efficiency. All of the studied energy resources are connected to a DC linked bus. The voltage of this bus is supplied to a three-phase inverter. Inverter output voltage is regulated for balanced and unba¬lanced loads. The generating capacity of the designed hybrid system is 5 kW and the system is simulated using MATLAB Simulink R2017a.

One of the priorities in the development of metallurgical enterprises is to increase own generation of electricity. At the largest enterprises in the sector – PJSC MMK (Magnitogorsk), Severstal PJSC (Cherepovets), PJSC “NLMK” (Lipetsk) Electricity generation is 60–70% of total consumption. This contributes to two factors: firstly, the presence of secondary fuel gases – coke and domain; and secondly, unreasonably high electricity tariffs. Thus there is an urgent need to ensure sustainable trouble-free operation of factory generators and basic systems. Automatic excitation control systems (ARV) are the most important factor when determining the state of the generator in various modes. The main requirements for ARV systems determine the specific working conditions. We will highlight the most significant and significant of these. 1. Low power 10–50 MW generators are connected to an external power system on 110 kV buses, where the short circuit capacity is within 3000–5000 mba. Thus the possibilities of regulating and maintaining voltage are very limited. 2. Since the electricity produced by its own power plants is 2–2.5 times cheaper than purchased power, almost all generators work with a power factor close to one. This significantly reduces their stability in the power supply system. 3. The voltage at the point of connection and loading of the Eigen needs for the generator voltage stations are unsta-ble. Therefore, in order to preserve the stability of generators in transient modes, the most preferred is the ARV system with a switching structure in which the settings and regulation laws are selected depending on Work modes. The work gives a general review of the existing laws and the proposed arousal regulation law, adapted to the condi-tions of factory generators of small and medium-sized power, working concomitantly with a high power grid.

Published: August 2022

District-distributed heating systems are considered to be the result of the development of existing district heating systems. In such the various energy technologies are integrated in order to achieve maximum efficiency of the heating for consumers. The distributed sector in these systems is associated, first of all, with the implementation of prosumers. The objective of the study is to define parameters for the reliability of components in the system which provide the required level of reliability of heating to consumers at the minimum cost. This is while ensuring the level of reliability while taking into account the reserve functions of prosumers. A methodology aimed at solving the objective thus stated was developed using various methods and models. These included: certain laws of reliability theory, nodal approach to the reliability analysis, models of the Markov random process, laws of thermophysical processes, heat load curve, etc. The proposed methods and models are presented within a comprehensive methodological schematic which includes the main stages of analysis and optimization (synthesis) of reliability. The methodological and computational tools thus developed were used to conduct a computational experiment for a test diagram of a heating system. The results obtained were analyzed, and their graphical interpretations presented. The conclusions and directions for further research were formulated.

Published: August 2022

Industrial crops and products have proved to be an excellent alternative to petro-based chemicals. Vegetable oils are rich in functional groups that can be transformed into monomers and polymers with applications such as biodiesel, lubricants, inks, coatings, and paints. This study describes the synthesis of rapeseed oil (RO)-based esteramide for the first time. The reaction was carried out by amidation of RO, producing diol fatty amide (N,N-bis(2-hydroxyethyl) RO fatty amide), followed by its esterification reaction with hippuric acid, resulting in RO-based hippurate amide (ROHA). Fourier-transform infrared spectroscopy and nuclear magnetic resonance confirmed the introduction of amide and ester moieties in ROHA. ROHA was further reinforced with silver nanoparticles (SNPs) to develop corrosion-protective nanocomposite coatings. ROHA/SNP coatings were scratch-resistant, impact-resistant, and flexible and showed good corrosion resistance performance toward 3.5 w/w% NaCl medium, with adequate corrosion protection efficiency, and antimicrobial behavior against Staphylococcus aureus, Chromobacterium violaceum, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans. ROHA/SNP coatings can be safely used up to 250°C.

Deep learning technology of Internet of Things Blockchain in distribution network faults
Authors: Zhang Hong , Li Rui , Shi Chuncheng
Published: August 2022

Nowadays, the development of human society and daily life are inseparable from the power supply. Therefore, people also put forward higher requirements for the reliability of distribution network, but power companies can only passively deal with distribution network failures, which is a bottleneck for the improvement of distribution network reliability. The Internet of Things (IoT) is the best solution for online equipment status monitoring and basic data sharing for large, widely distributed, relatively fixed, and large numbers of equipment. The construction of the IoT for power distribution equipment faces many important problems, including the selection of networking, equipment selection, and interaction standards. When researching the implementation plan, research on the distribution of IoT market was carried out. Based on the grid, the idea of optimizing the investment selection plan of the power distribution using IoT was discussed, and a result verification model was established. After the completion of the theoretical part, a case study of medium-voltage distribution grid equipment management and medium-voltage distribution network equipment management based on the grid was carried out by taking a real enterprise application situation as an example. Realizing fault diagnosis of distribution network will not only provide decision support for operation and maintenance of distribution network for power companies, but also have great economic and social benefits. Aiming at the shortcomings of single data mining method in distribution network fault diagnosis, hybrid data mining method is proposed. First, rough set theory is used to reduce the original fault data and form a simplified rule set. Because of the non-linearity of distribution network fault and the strong learning ability, adaptability, and robustness of Bayesian network, Bayesian network can be used to classify distribution network faults. Therefore, a simplified fault diagnosis system is established in this paper, and its correctness is confirmed. Then, the learning and training are carried out by using Bayesian network to call the simplest rule set, which has the characteristics of short learning and training time and high diagnostic accuracy.
Conditional conjunctions informed by Japanese and Korean
Authors: Kaufmann Magdalena , Whitman John
Published: August 2022

Many languages assign additional conditional interpretations to apparently regular sentential conjunctions (conditional conjunctions, CCs). Following previous ideas (Kaufmann, Magdalena. 2018.Topics in conditional conjunctions. Invited talk at NELS, vol. 49. Cornell University; Starr, Will. 2018. Conjoining imperatives and declaratives.Proceedings of Sinn und Bedeutung21. 1159–1176), we provide additional support for the hypothesis that CCs involve topicalized first conjuncts. We argue that Japanese and Korean, which appear to lack CCs, in fact mark them quite transparently. Both languages combine sentential conjunctions with topic markers: Japanese-te=wa(standardly considered one of the language’s conditional connectives) and Korean-ko=nun(occurring naturally, not discussed in the literature). We show that Japanese conditional=tofits into the pattern of CCs as well: it is derived by topicalization of conjunctive=to. Conjunctive=tois normally restricted to NPs, but it can coordinate finite clauses so long as the finite verb does not precede=to(Koizumi, Masatoshi. 2000. String vacuous overt verb raising.Journal of East Asian Linguistics9(3). 227–285). We argue that this requirement can be met in a topicalized clause carrying default tense; the resultant configuration is the conditional connective=to. Semantically, CCs are known to be more restricted thanif-conditionals in not readily realizing epistemic conditionals. The elements -te=wa,=to, and-ko=nunare all subject to exactly this restriction, which we refine to exclude only non-predictive epistemics. Following the transparent structure in Japanese and Korean, we interpret CCs by predicating the regular conjunction distributively of the set of (contextually salient and epistemically accessible) situations described by the topicalized first conjunct. We argue that apparent cases of focus on or within the first conjunct of CCs constitute contrastive topics or corrections.
Clinical relevance and translational impact of reduced penetrance in genetic movement disorders

Published: August 2022

Reduced penetrance is an important but underreported aspect in monogenic diseases. It refers to the phenomenon that carriers of pathogenic variants do not manifest with an overt disease. Clinical expressivity, on the other hand, describes the degree to which certain disease characteristics are present. In this article, we discuss the implications of reduced penetrance on genetic testing and counseling, outline how penetrance can be estimated in rare diseases using large cohorts and review the ethical, legal and social implications of studying non-manifesting carriers of pathogenic mutations. We highlight the interplay between reduced penetrance and the prodromal phase of a neurodegenerative disorder through the example of monogenic Parkinson’s disease and discuss the therapeutic implications.
Reduced penetrance of Parkinson’s disease models
Authors: Morais Vanessa A. , Vos Melissa
Published: August 2022

The etiology and progression of Parkinson’s Disease (PD), the second most prevalent neurological disorder, have been widely investigated for several decades; however, a cure is still lacking. Despite the development of several neurotoxins and animal models to study this rather heterogeneous disease, a complete recapitulation of the neurophysiology and neuropathology of PD has not been fully achieved. One underlying cause for this could be that mutations in PD-associated genes have reduced penetrance. Therefore, the quest for novel PD models is required where a double hit approach needs to be evoked – a combination of genetic alterations and environmental factors need to be accounted for in one unique model simultaneously.

Authors: Lopez Marifel C. , Punay Jaypeh Ju D. , Quinto Joseph Bello
Published: August 2022

The sudden shift from traditional to online learning because of the COVID-19 pandemic has made written communication the primary method for students and instructors to send and receive information. However, most students still experience challenges when communicating with their instructors in written form, especially first-year university students. Henceforth, this study aimed to understand the written communication challenges of freshman Bachelor of Arts in Communication (BACOM) students of S.Y. 2020-2021. Specifically, the study intended to determine the challenges encountered by the participants in written correspondence with their instructors in terms of online learning, the consequences of the challenges identified, and the ways to improve written communication between the participants and their instructors. This qualitative study used Hermeneutic Phenomenology in one state university in Cordillera Administrative Region, Philippines. Data was gathered through an online focus group interview which was analyzed using Reflexive Thematic Analysis. Findings of the study show that the major challenges endured by the students are uncertainty, sensitivity, comprehension deficit, poor internet connection, and grammar inaccuracies. As a result of these difficulties, the outcomes identified by the students are delayed inquiries, poor performance, low self-esteem, and a communication gap. Based on the students' suggestions, effective written communication can be improved between instructors and students by employing empathy, online etiquette, systematized platform, initiative, feedback, cooperation, clarity of instructions, clarity of concerns, and open communication. Chiefly, this study demonstrates that both students and instructors should be aware of their respective roles and duties to establish healthy, productive, and effective learning and communication now that the learning system has shifted online.
The implementation of bichronous online learning: EFL students’ perceptions and challenges
Authors: Utomo Dias Tiara Putri , Ahsanah Finaty
Published: August 2022

The COVID-19 pandemic has made online learning as a common instructional delivery today. Since various methods, approaches, and technologies are involved, it is important to understand students’ perceptions for taking further decision in teaching. The current research aimed to investigate Indonesian students’ perceptions of the implementation of bichronous online learning along with the challenges in the level of higher education. Bichronous online learning refers to the blending between asynchronous and synchronous online learning. In this study, asynchronous learning was carried out through Edmodo while the synchronous mode was implemented via Zoom. The participants were 57 first-year university students who experienced full bichronous online learning in the English for Specific Purposes class. This research applied explanatory sequential mixed-methods as suggested by Creswell (2014). The quantitative data were obtained by Likert-scale questionnaires while the qualitative data were acquired through interviews and observations. The results indicated that students had positive perceptions of bichronous online learning in terms of motivations, academic achievement, and communication and interactions. Bichronous online learning promoted students’ engagement, active interaction, and feedback exchange which highly contributed to their learning outcome. However, technical issues such as poor internet connection and limited data plan were the biggest challenges faced by the students. It is expected that educators can adjust which online learning tools are convenient to use and cater to students’ needs.

In brief

Elevated temperatures disturbed sperm physiology. Bovine sperm cells exposed to heat shock led to diminished mitochondrial activity, fertilizing ability, increased oxidative stress and caspase activity concomitant with a delay in embryonic developmental kinetics and modulation of sperm-borne microRNAsmiRNAs.

Sperm function is susceptible to adverse environmental conditions. It has been demonstrated that in vivo and in vitro exposure of bovine sperm to elevated temperature reduces sperm motility and fertilizing potential. However, the cascade of functional, cellular, and molecular events triggered by elevated temperature in the mature sperm cell remains not fully understood. Therefore, the aim of this study was to determine the effect of heat shock on mature sperm cells. Frozen-thawed Holstein sperm were evaluated immediately after Percoll purification (0 h non-incubation control) or after incubation at 35, 38.5, and 41°C for 4 h. Heat shock reduced sperm motility after 3–4 h at 41°C while mitochondrial activity was reduced by 38.5 and 41°C when compared to the control. Heat shock also increased sperm reactive oxygen species production and caspase activity. Heat-shocked sperm had lower fertilizing ability, which led to diminished cleavage and blastocyst rates. Preimplantation embryo developmental kinetics was also slowed and reduced by sperm heat shock. The microRNA (miR) profiling identified >300 miRs in bovine sperm. Among these, three and seven miRs were exclusively identified in sperm cells exposed to 35 and 41°C, respectively. Moreover, miR-181d was enriched in sperm cells exposed to higher temperatures. Hence, elevated temperature altered the physiology of mature sperm cells by perturbing cellular processes and the miR profile, which collectively led to lower fertilizing ability and preimplantation development.

In 2021 a group of 76 third-year undergraduate students, many of whom are prospective educators, designed six distinctly different accessible, open-access digital tools to “crip sex education” in partnership with disabled, Deaf, and queer community-based activists. This experiential education project, called “Cripping Sex Education: Developing Digital Tools for Disabled, Deaf, and Queer Kids,” began with a public panel discussion.
Accessibility of Canadian COVID-19 Testing Locations for People with Disabilities During the Third Wave of the COVID-19 Pandemic
Authors: Rotenberg Sara , Cooper Jane , Downer Matthew B.
Published: August 2022

Background: Canadians with disabilities make up nearly a quarter of the population yet faced barriers in accessing information about COVID-19 testing accessibility across the country. Objective: This study aimed to understand the availability of accessibility information for COVID-19 testing sites in Canada. To date, no known studies have evaluated the availability of accessibility information online.Methods: An environmental scan of COVID-19 testing websites was conducted (1) nationally through the provincial/territorial websites for COVID-19 testing and (2) in Ontario, where there was individual location information. Data on key accessibility features were extracted from the website to simulate the user experience of booking a COVID-19 test during March 2021. Results: All provinces and territories provided minimal accessibility information on their provincial or territorial COVID-19 testing websites. Only Ontario included accessibility information for individual testing locations. Out of 170 individual testing locations in Ontario, few had information about accessibility, with only 8.2% listing at least 3 of the 5 key accessibility features measured on their websites.Conclusions: This study demonstrates that, more than a year into the pandemic, there existed a clear lack of accessibility information for testing locations for Canadians with disabilities.
Access and Inclusion: The Experiences of Postsecondary Students with Mobility-Related Physical Disabilities

Published: August 2022

Relatively little is known about how physical and social environments influence access to and inclusion in educational and leisure activities for students with a mobility-related physical disability attending a post-secondary institution. Understanding how environments shape access is important because educational and leisure activities affect one’s emotional, social, mental, and physical health. The aim of this qualitative exploratory study was to gain an understanding of the lived experiences of access and inclusion for students with a mobility-related physical disability, and specifically, the barriers and facilitators within the physical and social environments which shape access and inclusion. One-on-one semi-structured interviews were conducted with nine students attending a post-secondary institution in Nova Scotia, Canada who self-identified as living with a mobility-related physical disability. From an analysis of the interviews, five themes emerged: 1) navigating disclosure; 2) invisibility (and passing) and visibility; 3) accommodations and supports; 4) the prevailing conceptualization of mobility-related disabilities; and 5) places and spaces for the “normal” body. Although there have been actions taken by the post-secondary institution to transform environments and improve access and inclusion, additional efforts are urgently needed, and it is suggested that Universal Design is one possible strategy.

BACKGROUND

Little is known about the epidemiology and outcomes of neurologic complications associated with coronavirus disease 2019 (COVID-19) in children.

METHODS

We performed a cross-sectional study of children 2 months to <18 years of age with COVID-19 discharged from 52 children’s hospitals from March 2020 to March 2022. Neurologic complications were defined as encephalopathy, encephalitis, aseptic meningitis, febrile seizure, nonfebrile seizure, brain abscess and bacterial meningitis, Reye’s syndrome, and cerebral infarction. We assessed length of stay (LOS), ICU admission, 30 day readmissions, deaths, and hospital costs. We used multivariable logistic regression to identify factors associated with neurologic complications.

RESULTS

Of 15 137 children hospitalized with COVID-19, 1060 (7.0%) had a concurrent diagnosis of a neurologic complication. The most frequent neurologic complications were febrile seizures (3.9%), nonfebrile seizures (2.3%), and encephalopathy (2.2%). Hospital LOS, ICU admission, ICU LOS, 30 day readmissions, deaths, and hospital costs were higher in children with neurologic complications compared with those without complications. Factors associated with lower odds of neurologic complications included: younger age (adjusted odds ratio [aOR]: 0.97; 95% confidence interval [CI]: 0.96–0.98), occurrence during delta variant predominant time period (aOR: 0.71; 95% CI: 0.57–0.87), presence of a nonneurologic complex chronic condition (aOR: 0.80; 95% CI: 0.69–0.94). The presence of a neurologic complex chronic condition was associated with higher odds of neurologic complication (aOR 4.14, 95% CI 3.48–4.92).

CONCLUSIONS

Neurologic complications are common in children hospitalized with COVID-19 and are associated with worse hospital outcomes. Our findings emphasize the importance of COVID-19 immunization in children, especially in high-risk populations, such as those with neurologic comorbidity.
Opacidade literária como conhecimento literário
Authors: Maciel Washington Morales
Published: August 2022

O objetivo geral desta contribuição é elucidar um dilema envolvido no debate sobre a relação entre o conhecimento teórico-prático e o valor estético da literatura. Para atingir esse objetivo, são analisados os argumentos defendidos por Peter Lamarque contra a redução epistêmica do valor literário. Em primeiro lugar, mostra-se que a defesa do valor cognitivo da literatura não necessariamente implica um compromisso com uma teoria proposicional do valor estético da literatura. Em segundo, que o que determina o valor estético da literatura é a forma específica com que ganha a “batalha pelas ideias”. Portanto, segundo esta interpretação desse dilema, a opacidade narrativa não só não exclui de maneira alguma o nosso conhecimento de mundo, como a forma específica de conhecimento literário que ela constitui é o que explica o valor estético das obras literárias.
Introduction to Hearing Voices and Other Matters of the Mind
Authors: Apud Ismael
Published: August 2022

In the book Hearing Voices and Other Matters of the Mind, McCauley and Graham present a novel contribution to the Cognitive Science of Religion. The authors propose a naturalistic, pluralistic, and interdisciplinary approach to analyze the continuities between normal cognition, religious cognition, and abnormal cognition. McCauley and Graham use the idea of maturationally natural systems to understand different religious “abnormal” experiences: hearing voices from God or other spiritual beings, mood disorders caused by a failure in petitionary prayer, religious scrupulosity and its resemblance with Obsessive-Compulsive symptoms, and the “mindblind atheism” of Autistic Spectrum Disorder. Despite some minor weaknesses, e.g., an excessive use of maturationally natural systems to explain religious phenomena, the book is an important contribution to the Cognitive Science of Religion.

Gods in Disorder
Authors: McCauley Robert N. , Graham George
Published: August 2022

Commentators’ concerns occasion clarifications of positions in Hearing Voices and Other Matters of the Mind. Philosophical naturalism holds that philosophers needlessly handicap their projects if they ignore the sciences. Ecumenical Naturalism maintains that similar forms of cognition and experience associated with religiosity and mental disorders may submit to similar scientific explanations. The by-product theory, which looks to the operations of maturationally natural cognitive capacities to explain religious representations’ forms, offers explanatory leverage with regard to some mental disorders. The fact that examples are mostly American, Christian, and Western need not preclude the accounts’ broader applicability. Explanatory pluralism endorses many explanatory approaches. The aim is only to show how much cognitive considerations can do, not to suggest that they provide comprehensive theories of anything. Other telling proposals will enhance understanding of these matters. The operations of maturationally natural dispositions, regardless of how they are cued, contribute to what humans take to be meaningful.
