Authors: Aljamhan Abdullah , Habib Syed Rashid , AlSarhan Mohammed A. , AlZahrani Bashayer , AlOtaibi Hessa , AlSunaidi Norah
Published: February 2021

Objective:

The aim of this in vitro study was to compare the effect of three finishing/polishing systems on the surface roughness (Ra) of conventional and Bulk-fill composite resins.

Materials and methods:

The Ra values of three different brands of Bulk-fill composites (Filtek Bulk-fill®, 3M ESPE; SonicFill Bulk-fill®, Kerr; SDR Bulk-fill®, Dentsply) were tested and compared with the Ra of a conventional composite (Filtek XT Z350®, 3M ESPE). A total of 30 discs (10 mm × 2 mm) were fabricated from four test materials and divided into three groups (n = 10/group) depending on the three finishing/polishing systems used (Astropol®, Ivoclar Vivadent; PoGo®, Dentsply; Sof-LexTM®, 3M ESPE). The Ra of each specimen was recorded with an optical profilometer (Contour-GT-X®, USA). ANOVA and Tukey’s tests were used for statistical analysis.

Results:

Statistically significant differences (P < 0.05) were observed between the Ra values of all composite materials tested with three finishing/polishing systems. Among composite materials, only Group-III showed a significant difference (P = 0.003) in Ra obtained using all three finishing/polishing systems. SDR Bulk-fill® and Filtek XT Z350® showed the highest (0.810 ± 0.373 µm) and lowest (0.365 ± 0.119 µm) Ra values, respectively. Individually, the highest Ra was recorded for SDR Bulk-fill® when it was finished/polished with the Astropol® system. SonicFill Bulk-fill® and SDR Bulk-fill® composites exhibited the lowest Ra values when they were finished with the PoGo® system.

Conclusion:

Finishing and polishing techniques greatly affect the surface roughness of different Bulk-fill composites because variations in the surface roughness were observed for all tested composite materials. Filtek XT Z350® exhibited the lowest surface roughness, while SDR Bulk-fill® exhibited the highest surface roughness among the tested composite materials.

Authors: Husna Cut , Yahya Mustanir , Kamil Hajjul , Tahlil Teuku
Published: February 2021

Introduction:

Indonesia, being a part of the Pacific “ring of fire,” is prone to disasters. Several disasters occurred from 2004 to 2019, which resulted in the loss of many lives. These disasters impacted the physical, psychological, psychosocial, and spiritual conditions of survivors. Nurses are the frontline care providers who need adequate competencies to respond to disasters.

Objective:

This study aimed to explore the nurses’ perception of disaster, roles, barriers, and Islamic-based nurses’ competencies in managing psychological, psychosocial, and spiritual problems due to disasters in hospital settings.

Methods:

This is a qualitative study conducted in three large referral hospitals in Banda Aceh, Indonesia. Focus group discussion was conducted on 24 nurses from three hospitals using the discussion guide consisting of five open-ended questions. The data was analyzed through inductive content analysis.

Results:

The study found four themes of Islamic nurses’ competencies in disaster response: 1) perception about the disaster is influenced by religiosity, belief, and values, 2) communication skills, 3) nurses’ roles in disaster response consisted of disaster competencies (the use of Islamic values in managing patients’ conditions, and family engagement, 4) competency barriers consisted of inadequate training, insufficient Islamic-based services, and inadequate involvement of policymakers. This study explored Islamic nurses’ competencies in disaster response related perceptions about the disaster, nurses’ roles, and barriers. The limitation and future of the study were also discussed.

Conclusion:

Perceptions, roles, and barriers in disaster response might influence the development of the Islamic-based nurses’ competencies in care delivery.
Epigenetic Repair of Terrifying Lucid Dreams by Enhanced Brain Reward Functional Connectivity and Induction of Dopaminergic Homeo - static Signaling

Published: February 2021

During Lucid Dreams, the dreamer is aware, experiences the dream as if fully awake,
and may control the dream content. The dreamer can start, stop, and restart dreaming, depending
on the nature and pleasantness of the dream. For patients with Reward Deficiency Syndrome (RDS)
behaviors, like Attention Deficit Hyperactivity Disorder (ADHD), Tourette's-Syndrome, and
Posttraumatic Stress Disorder (PTSD), the dream content may be pleasant, unpleasant, or terrifying.
A sample of psychiatric center patients identified as having RDS reported the effectiveness of
a neuronutrient, dopamine agonist, KB200Z, in combating terrifying, lucid dreaming. These reports
motivated the study of eight clinical cases with known histories of substance abuse, childhood
abuse, and PTSD. The administration of KB200Z, associated with eliminating unpleasant or
terrifying lucid dreams in 87.5% of the cases. Subsequently, other published cases have further
established the possibility of the long-term elimination of terrifying dreams in PTSD and ADHD
patients. Induction of dopamine homeostasis may mitigate the effects of neurogenetic and epigenetic
changes in neuroplasticity, identified in the pathogenesis of PTSD and ADHD. The article explores
how relief of terrifying lucid dreams may benefit from modulation of dopaminergic signaling
activated by the administration of a neuronutrient. Recently, precision formulations of the
KB220 neuronutrient guided by Genetic Addiction Risk Severity (GARS) test results have been
used to repair inheritable deficiencies within the brain reward circuitry. The proposition is that improved
dopamine transmodulational signaling may stimulate positive cognitive recall and subsequently
attenuate the harmful epigenetic insults from trauma.

Published: February 2021

Background:

The risk for all addictive drug and non-drug behaviors, especially, in the
unmyelinated Prefrontal Cortex (PFC) of adolescents, is important and complex. Many animal and
human studies show the epigenetic impact on the developing brain in adolescents, compared to
adults. Some reveal an underlying hyperdopaminergia that seems to set our youth up for risky behaviors
by inducing high quanta pre-synaptic dopamine release at reward site neurons. In addition,
altered reward gene expression in adolescents caused epigenetically by social defeat, like bullying,
can continue into adulthood. In contrast, there is also evidence that epigenetic events can elicit adolescent
hypodopaminergia. This complexity suggests that neuroscience cannot make a definitive
claim that all adolescents carry a hyperdopaminergia trait.

Objective:

The primary issue involves the question of whether there exists a mixed hypo or hyper -
dopaminergia in this population.

Methods:

Genetic Addiction Risk Score (GARS®) testing was carried out of 24 Caucasians of ages
12-19, derived from families with RDS.

Results:

We have found that adolescents from this cohort, derived from RDS parents, displayed a
high risk for any addictive behavior (a hypodopaminergia), especially, drug-seeking (95%) and alcohol-
seeking (64%).

Conclusion:

The adolescents in our study, although more work is required, show a hypodopaminergic
trait, derived from a family with Reward Deficiency Syndrome (RDS). Certainly, in future
studies, we will analyze GARS in non-RDS Caucasians between the ages of 12-19. The suggestion
is first to identify risk alleles with the GARS test and, then, use well-researched precision, pro-dopamine
neutraceutical regulation. This “two-hit” approach might prevent tragic fatalities among
adolescents, in the face of the American opioid/psychostimulant epidemic.

Published: February 2021

This research aimed at investigating the influence of combination therapy of cupping and Pece Kau'a on hypertensive patients. The research design that was utilized was experimental design by a pretest-posttest control group approach. The population of this research was all patients who suffered from hypertension in Bima City, West Nusa Tenggara Province in Indonesia. The sample in this research was 60 respondents and this sampling utilized a randomized control trial. The results showed that combination therapy of dry cupping and Pece Kau'a on hypertensive patients could reduce the average of systolic and diastolic blood pressure with a p-value of 0.000. Therapy of dry cupping and Pece Kau’a is expected to be an alternative for medical action in nursing services both in hospitals and Public Health Centers. Besides, the combination therapy of dry cupping and Pece Kau’a could be developed more again.

Published: February 2021

Background: Learning environment is a broad concept that expresses the physical environments, contexts, and cultures where learning takes place. This study is aimed to evaluate the preclinical learning environment of a medical faculty using the Dundee Ready Education Environment Measure. Method: The study was designed as a descriptive cross-sectional study. The population of the study was determined as medical school students enrolled at Suleyman Demirel University, Faculty of Medicine, 1st year, 2nd year, and 3rd-year students during the 2019-2020 academic year (N: 884). Item analyzes, reliability tests, and validation tests were performed to evaluate the correlation of the scale with the population of the study. In line with this information, it was decided that the population was suitable for the scale and that generalization could be made through this data. Results: In the study, the data of 326 participants were evaluated. In the collective evaluation of all years overall DREEM-TR score as 138.07 ± 22.75 regarding all students. In comparison between years, it was seen that there was a statistically significant difference between 1st year and 2nd and 3rd years (p<.005). Discussion: The use of valid/reliable measurement tools in the evaluation of the program is necessary for the monitorization of the program. These valuable findings are suggested to be used by the faculty management for the development and monitorization of the program. We believe that the continuity of this evaluation within the scope of program evaluation would contribute to the monitoring and development of the training program.

Published: February 2021

Pseudocercospora fijiensis is a filamentous, hemi[B1] biotrophic fungus whose infection process in banana comprises biotrophic and necrotrophic phases; the biotrophic phase is the longer and less damaging of the two but is nonetheless a crucial stage of fungal establishment in the host. To discover the genes essential in this stage, we conducted an interaction experiment to isolate the transcriptome of the P. fijiensis and Musa acuminata interaction during the first 9 days of infection. Of more than 7000 P. fijiensis genes identified, the fifteen most highly expressed genes (RPKM>500) were analyzed. Specific non-canonical effector candidates were identified following in silico characterization which may be fundamental to pathogenicity. This report reveals essential details of a poorly-elucidated stage of the P. fijiensis-Musa sp. pathosystem.

Published: February 2021

The root-knot nematode, Meloidogyne spp., is an endoparasite that infects plants' root system and causes yield losses in several important crops. Meloidogyne is one of the most devastating pests, so searching for effective biological agents is needed to mitigate its damage. In this study, the predatory activity of Arthrobotrys oligosporus Fresen strain C-2197, obtained from a tropical dry forest of Ecuador, was evaluated as a biocontrol alternative for root-knot caused by Meloidogyne spp. Our results showed that A. oligosporus C-2197 has predatory activity against juvenile nematodes, 72.31%, and 79% efficacy, for in vitro and greenhouse conditions. Besides, the studied strain showed growth-promoting activity, increasing leaf and root area of inoculated plants. Growth promoting activity was also observed in field tests. The present study validates the potential use of A. oligosporus as a biocontrol of Meloidogyne spp. in tomato production systems under greenhouse. It also presents useful information on the use of different cultivation media and substrates for massive A. oligosporus spore concentrates.

Published: February 2021

Thermal treatment of acidified bovine whey is one of the most efficient traditional methods for the recovery and use of residual proteins in this byproduct and an alternative way of sustainable use of this type of resource. The yield of protein recovery from residual whey obtained as a byproduct was evaluated using the acid thermo-coagulation method. Bovine whey samples were collected in dry and rainy seasons and were subjected to acid thermo-coagulation, and the protein sample preparation was achieved using the TCA/Acetone and TCA/Acetone/Phenol methods. The determination of peptides was accomplished by electrophoresis SDS-PAGE. The TCA/Acetone/Phenol method reported better performance with a higher yield (22.2 μg/ml) than the classic TCA/Acetone method (8.8 μg/ml). The proteins found in higher proportion in whey samples of the dry season, representing 82.6 % of the total protein content, while in whey samples of rainy season equivalent up to 65.4 % of total proteins. The acid thermo-coagulation technique showed high-efficiency performance in whey peptide recovery.

Telemetric Interventions Offer New Opportunities for Managing Type 1 Diabetes Mellitus: Systematic Meta-review
Authors: Eberle Claudia , Stichling Stefanie
Published: February 2021

Background

The prevalence of diabetes mellitus (DM) is increasing rapidly worldwide. Simultaneously, technological advances are offering new opportunities for better management of type 1 diabetes mellitus (T1DM). Telemetry, the remote acquisition of patient data via a telecommunication system, is a promising field of application in eHealth and is rapidly gaining importance.

Objective

The aim of this study was to summarize the current evidences available on the effectiveness of telemetric approaches in T1DM management. This systematic meta-review examined different types of interventions of the technologies used in communication between health care professionals and patients as well as the key outcomes.

Methods

We performed a systematic search in Web of Science Core Collection, EMBASE, Cochrane Library, MEDLINE via PubMed, and CINAHL databases in April 2020 with regard to the effectiveness of telemetric interventions for T1DM. We classified the interventions into 4 categories according to the technology used: (1) real-time video communication, (2) real-time audio communication, (3) asynchronous communication, and (4) combined forms of communication (real-time and asynchronous). We considered various study designs such as systematic reviews, clinical trials, meta-analyses, and randomized controlled trials and focused on the key outcomes. Additionally, a funnel plot based on hemoglobin A1c (HbA1c) values and different quality assessments were performed.

Results

We identified 17 (6 high quality and 9 moderate quality) eligible publications: randomized controlled trials (n=9), systematic reviews and meta-analyses (n=5), cohort studies (n=2), and qualitative publications (n=1). Of 12 studies, 8 (67%) indicated a (significant or nonsignificant) reduction in HbA1c levels; 65% (11/17) of the studies reported overall (mildly) positive effects of telemetric interventions by addressing all the measured outcomes. Asynchronous interventions were the most successful for patients diagnosed with T1DM, but no technology was clearly superior. However, there were many nonsignificant results and not sustained effects, and in some studies, the control group benefited from telemetric support or increased frequency of contacts.

Conclusions

Based on the currently available literature, this systematic meta-review shows that telemetric interventions cause significant reduction in HbA1c levels and result in overall positive effects in T1DM management. However, more specified effects of telemetric approaches in T1DM management should be analyzed in detail in larger cohorts.

Authors: Fehribach Jamie Rhiannon , Toffolo Marieke Bianca Jolien , Cornelisz Ilja , van Klaveren Chris , van Straten Annemieke , van Gelder Jean-Louis , Donker Tara
Published: February 2021

Background

Aviophobia (the fear of flying) can greatly impact the daily life functioning of people with the condition. Traditional exposure-based treatment is hampered by the limited availability of airplane practice situations, which is a result of economical and practical concerns. Easily accessible and low-cost virtual reality exposure therapy may address these challenges.

Objective

The purpose of our study is to investigate the effectiveness of ZeroPhobia: Aviophobia (a self-help mobile app–based treatment) in reducing flight anxiety symptoms and depressive and anxiety symptoms. We will also investigate the effects of usage intensity, the sense of immersion, inherent absorption ability, and perceived user-friendliness on the treatment effect.

Methods

Participants (N=114) who are aged 18-64 years and experience at least mild symptoms of aviophobia will be recruited from the general Dutch population and randomized into a treatment group or waitlist control group. By using their own phones and rudimentary mobile virtual reality headsets, participants will receive six modules of psychoeducation and cognitive behavioral therapy, which will include six levels of virtual reality exposure therapy over a period of 6 weeks. Assessments will be conducted at baseline, posttest (ie, after 6 weeks), and 3- and 12-month follow-ups. The primary outcome measure of our study is the Flight Anxiety Situations Questionnaire. The secondary outcome measures include anxiety and depression measures and additional covariates (including usage intensity, the degree of immersion, etc). We will test treatment effectiveness by conducting an intention-to-treat analysis and estimating average treatment effects on the treated. The mechanisms of treatment effect will also be explored.

Results

The study was funded on September 25, 2018. Ethical approval was received on October 11, 2019. Recruitment closed on May 7, 2020.

Conclusions

Our study will further the scientific understanding and clinical implications of technology’s current ability to aid in providing effective, accessible treatment for the fear of flying.

Minimizing the Impact of the COVID-19 Epidemic on Oncology Clinical Trials: Retrospective Study of Beijing Cancer Hospital
Authors: Fu Zhiying , Jiang Min , Wang Kun , Li Jian
Published: February 2021

Background

In view of repeated COVID-19 outbreaks in most countries, clinical trials will continue to be conducted under outbreak prevention and control measures for the next few years. It is very significant to explore an optimal clinical trial management model during the outbreak period to provide reference and insight for other clinical trial centers worldwide.

Objective

The aim of this study was to explore the management strategies used to minimize the impact of the COVID-19 epidemic on oncology clinical trials.

Methods

We implemented a remote management model to maintain clinical trials conducted at Beijing Cancer Hospital, which realized remote project approval, remote initiation, remote visits, remote administration and remote monitoring to get through two COVID-19 outbreaks in the capital city from February to April and June to July 2020. The effectiveness of measures was evaluated as differences in rates of protocol compliance, participants lost to follow-up, participant withdrawal, disease progression, participant mortality, and detection of monitoring problems.

Results

During the late of the first outbreak, modifications were made in trial processing, participant management and quality control, which allowed the hospital to ensure the smooth conduct of 572 trials, with a protocol compliance rate of 85.24% for 3718 participants across both outbreaks. No COVID-19 infections were recorded among participants or trial staff, and no major procedural errors occurred between February and July 2020. These measures led to significantly higher rates of protocol compliance and significantly lower rates of loss to follow-up or withdrawal after the second outbreak than after the first, without affecting rates of disease progression or mortality. The hospital provided trial sponsors with a remote monitoring system in a timely manner, and 3820 trial issues were identified.

Conclusions

When public health emergencies occur, an optimal clinical trial model combining on-site and remote management could guarantee the health care and treatment needs of clinical trial participants, in which remote management plays a key role.
Developmental Assets of Adolescents and Young Adults With Chronic Illness and Comorbid Depression: Qualitative Study Using YouTube (Preprint)
Authors: Zheng Katherine , George Maureen , Roehlkepartain Eugene , Santelli John , Bruzzese Jean-Marie , Smaldone Arlene
Published: February 2021

BACKGROUND

Developmental assets provide a framework for optimizing development among adolescents but have not been studied in adolescents with chronic illness and comorbid depression, which is a group at risk for poor health outcomes. YouTube postings provide valuable insights to understand this understudied population.

OBJECTIVE

This study aims to explore asset development from the perspectives of adolescents and young adults (AYAs) with chronic illness and comorbid depression.

METHODS

YouTube was searched using 12 chronic illnesses (eg, diabetes) coupled with “depression” as keywords. Videos were included if they were uploaded by AYAs aged between 11 and 29 years and discussed living with chronic illness and depression during adolescence. Video transcripts were coded deductively for 40 internal and external assets that constitute the Developmental Assets Framework. Categories not captured by deductive coding were identified using conventional content analysis. Categories and their respective assets were labeled as being discussed either negatively or positively.

RESULTS

In total, 31 videos from 16 AYAs met the inclusion criteria. A total of 7 asset categories, support, constructive use of time, boundaries and expectations (external assets), identity, commitment to learning, positive values, and social competence (internal assets), reflecting 25 (13 internal; 12 external) assets, were discussed. Internal assets, particularly relating to identity, were commonly discussed by AYAs either in a negative way or fluctuated between positive and negative perspectives.

CONCLUSIONS

In this sample of AYAs with chronic illness and comorbid depression, internal assets were commonly discussed in a negative way. Future research is needed to better understand how assets develop and if the Developmental Assets Framework adequately represents the experiences of this population.
Understanding the Effects of Participation in a Large-scale Remote Diabetes Monitoring Program: A Qualitative Survey and Retrospective Analysis Study (Preprint)
Authors: Chew Yee Chieh , Swiernik Michael , McCormick Thomas , Stevens Angie
Published: February 2021

BACKGROUND

Remote patient monitoring has shown promise in helping management of population health by facilitating care management between providers and patients by providing real-time accurate data of relevant readings for chronic conditions from outside a medical facility. Kaiser Permanente offers remote patient monitoring as part of a holistic care management program for its members.

OBJECTIVE

The purpose of this study was to examine qualitative and quantitative measures of patient and provider feedback of Kaiser Permanente’s remote patient monitoring program for diabetes, patient perspectives on ability to manage diabetic care, patient health outcomes and program adherence, and utilization of Kaiser Permanente services under the program.

METHODS

In this study, patients who were enrolled in the RPM program in Southern California from 2017 onwards as well as care providers who had enrolled at least one patient in the program were studied. For qualitative data, online surveys were deployed. For quantitative analysis, clinical and demographic data drawn from existing data systems, which included Kaiser Permanente membership records, encounter records, electronic medical records, and administrative data repositories were used.

RESULTS

Providers (N=160) and patients (N=1,106) responded to the survey and reported many qualitative benefits from participating in the study, including improved coordination of clinical care and increased accountability. Patients who were enrolled in the program experienced a mean decrease of 1.25 in HbA1c results and an increase in encounters over 90 days which gradually come back to pre-enrollment encounter levels around 6 months. Those who actively upload glucose readings met the program upload goals within the first month a majority (92%) of the time.

CONCLUSIONS

There are many qualitative benefits for patients and providers incorporating Kaiser Permanente’s remote patient monitoring program as part of diabetic care. The quantitative descriptions of health outcomes, service utilization, and program adherence speak to the feasibility and value of deploying remote monitoring tools at scale within healthcare organizations.

LINE-START SYNCHRONOUS MOTOR A VIABLE ALTERNATIVE TO ASYNCHRONOUS MOTOR
Authors: Šarac Vasilija
Published: February 2021

Advancements in power electronics that contributed to the easier starting of synchronous permanent magnet motors have increased the significance of this type of motors, widely known as not–self-starting motors. However, power electronics, which is necessary, for the starting of the synchronous motor contributed also to the complexity of this type of motor drives as well as to increased operational and maintenance cost. The line-start synchronous motors have gained the popularity during recent years as a viable alternative to asynchronous motors due to an easy line starting similar to the asynchronous motors and good operational parameters such as high efficiency and power factor. The paper presents the design of a line-start synchronous motor, derived from an asynchronous motor, by redesigning the rotor with flux barriers and permanent magnets. The computer models for calculating parameters and operating characteristics of both motors were modeled and the accuracy of the obtained results was verified by comparison with experimental data. Motor transient characteristics of speed, current and torque for the line starting of the both motors, when they were fed with the voltage from the network, were determined as well. The obtained transient characteristics of both motors were compared and adequate conclusions regarding line starting of both motors were derived. The newly derived synchronous motor for line starting has good operational characteristics such as increased efficiency, power factor and starting torque compared with the respected parameters of the asynchronous motor, good transient and steady-state operating characteristics and good dynamic response at sudden load change.

A CASE STUDY ON THE MORPHO-PHONOLOGICAL STATUS OF SERBIAN ADJECTIVAL DERIVATIONAL SUFFIXES WITH INITIAL J
Authors: Janić Aleksandra A.
Published: February 2021

The subject of this paper is the status of Serbian adjectival derivational suffixes with initial j in comparison to their variants with initial lj, nj, and also without an initial consonant. Azbučnik prideva u srpskoj prozi dvadesetog veka by Miroslav Josić Višnjić was used as a corpus. The most favourable possible scenario for adjectival derivational suffixes ‑jan, -j(a)n, ‑jav, ‑jast, ‑ji, ‑jiv, ‑jal(a)n, ‑jar(a)n, -jat, -jev, ‑jevit, -jikav, -jin, ‑jit, ‑juškast and their distribution were analysed regarding the phonological characteristics of the final consonant of a derivational base they are combined with. These derivational suffixes with initial j in Serbian are the most stable with n and l at the end of a base (n + j from a derivational suffix > the phoneme nj, l + j from a derivational suffix > the phoneme lj), but they are rarely visible on the surface structure of adjectives (cf. pasji). In word formation analyses, adjectives with derivational bases with final nj, lj and other palatal and palatalised consonants can be morpho-phonologically explained with derivational suffixes with an initial j, but some of them also with initial nj, lj or without initial consonant.

Published: February 2021

Decision and policy-makers in multi-criteria decision-making analysis take into account some strategies in order to analyze outcomes and to finally make an effective and more precise decision. Among those strategies, the modification of the normalization process in the multiple-criteria decision-making algorithm is still a question due to the confrontation of many normalization tools. Normalization is the basic action in defining and solving a MADM problem and a MADM model. Normalization is the first, also necessary, step in solving, i.e. the application of a MADM method.  It is a fact that the selection of normalization methods has a direct effect on the results. One of the latest normalization methods introduced is the Logarithmic Normalization (LN) method. This new method has a distinguished advantage, reflecting in that a sum of the normalized values of criteria always equals 1. This normalization method had never been applied in any MADM methods before. This research study is focused on the analysis of the classical MADM methods based on logarithmic normalization. VIKOR and TOPSIS, as the two famous MADM methods, were selected for this reanalysis research study. Two numerical examples were checked in both methods, based on both the classical and the novel ways based on the LN. The results indicate that there are differences between the two approaches. Eventually, a sensitivity analysis is also designed to illustrate the reliability of the final results.
FUZZY MODEL OF THE OPERATIONAL POTENTIAL CONSUMPTION PROCESS OF A COMPLEX TECHNICAL SYSTEM
Authors: Pająk Michał
Published: February 2021

During the operation process of a system its technical state is changed. The changes take place because of the wearing factors impact. The impact depends on the flow and intensity of the operation process what is characterized by the time histories of the working parameters. Simultaneously, the changes of the technical state are correlated with the changes of the amount of the operational potential included in a system. In order to avoid the inability state occurrence the amount of this potential should be higher than the boundary value. The amount of the operational potential included in a system is determined by the values of the cardinal features of it but in the case of the real technical system the values cannot always be measured. Therefore, the amount of the operational potential and the technical state of the system cannot always be determined online. To solve this problem the model of the operational potential consumption process was created and presented in the paper. The model uses artificial intelligence techniques to calculate the change of the operational potential amount by determining the changes of the cardinal features of the system on the basis of the time histories of the working parameters. The verification of the model quality was performed using the pulverized boiler OP-650k-040 operating in the power plant. The description of the conducted research and the results of the verification were presented in the end of the paper proving the adequacy of the model implementation in the case of industrial objects.

Published: February 2021

In the present work, multi-response optimization of electro-discharge machining (EDM) process is carried out based on an experimental analysis of machining superalloy Inconel-718. The study aims at optimizing and determining an optimal set of process variables, namely discharge current (), pulse-on duration () and dielectric fluid-pressure () for achieving optimal machining performance in EDM. Nine independent experiments based on L9 orthogonal array are carried out by using tungsten as the electrode. The productivity performance of the EDM process is measured in terms of material removal rate (MRR) and its cost parameter is measured in terms of tool wear rate (TWR) and electrode wear rate (EWR). The TOPSIS is used in conjunction with five different criterion weight allocation strategies— (namely, mean weight (MW), standard deviation (SDV), entropy, analytic hierarchy process (AHP) and Fuzzy). While MW, SDV and entropy are based on the objective evaluation of the decision-maker (DM), the AHP can model the DM’s subjective evaluation. On the other hand, the uncertainty in the DM’s evaluation is analyzed by using the fuzzy weighing approach.
SIMULATION OF A SINGLE THIRD-BODY PARTICLE IN FRICTIONAL CONTACT
Authors: Li Qiang
Published: February 2021

Contact of a single third-body particle between two plates is simulated using the Boundary Element Method. The particle is considered as deformable, and the Coulomb’s law of friction is assumed at the contact interface. The normal pressure distribution and tangential stress distribution in contact as well as the macroscopic force and force moment are calculated. Several movement modes are shown to be possible: rolling, rotation, or sticking during the loading. It is found that, differing from rigid particles, the state of particle may change during the loading. The particle may stick to the plates initially, but rotation may occur when the load becomes larger. Examples with the same and different coefficients of friction are presented to show kinematics of particle. The method can be further applied to simulation of multiple third-body particles.

Published: February 2021

Close packed carbon nanotube bundles are materials with highly deformable elements, for which unusual deformation mechanisms are expected. Structural evolution of the zigzag carbon nanotube bundle subjected to biaxial lateral compression with the subsequent shear straining is studied under plane strain conditions using the chain model with a reduced number of degrees of freedom. Biaxial compression results in bending of carbon nanotubes walls and formation of the characteristic pattern, when nanotube cross-sections are inclined in the opposite directions alternatively in the parallel close-packed rows. Subsequent shearing up to a certain shear strain leads to an appearance of shear bands and vortex-like displacements. Stress components and potential energy as the functions of shear strain for different values of the biaxial volumetric strain are analyzed in detail. A new mechanism of carbon nanotube bundle shear deformation through cooperative, vortex-like displacements of nanotube cross sections is reported.
Two letters from V. Bryusov to P. Bartenev
Authors: Orlova Monika V. , Lavrov Alexander V.
Published: February 2021

The publication complements the materials collected in the book Valery Bryusov as a literary historian (Moscow, 2019, series “Literary Heritage Library”, edited by N.A. Bogomolov and A.V. Lavrov) that contains Bryusov’s correspondence with P.I. Bartenev and N.O. Lerner. The correspondence of Valery Bryusov and Petr Bartenev includes, among others, 39 Bryusov’s letters of 1898–1909, preserved in the Russian State Archive of Literature and Arts. The corpus of Bryusov–Bartenev correspondence reflects the poet’s work as a secretary, contributor, reviewer in the journal of history and literary history Russkiy Arkhiv (Russian Archive) edited by Bartenev (Bryusov has become an outstanding Russian classical poetry expert of his time). Two more Bryusov’s letters relating to Bartenev’s last years have been recently discovered. They are preserved in the State Literary Museum Manuscript Department and shed light on some details of Bryusov’s relations with Bartenev, as well as their shared interest in classical literature, and provide some additional data for the biographies of Bryusov and his correspondent — a contemporary of Tyutchev, Pogodin, the Aksakovs, an “archive-digger”, described by Bryusov as “a committed publisher of historical materials” and viewed by the poet as a person not at all alien to literature and culture of the early 20th century.
