Authors:   Omsk State Technical University, Mansurova S. E.
Published: December 2022

The type structure of Electronic Educational Resources (EER) created for students, research and educational employees is considered. The development trends in the digital services of online education are presented. Open access educational materials on websites of the University libraries are analysed. A large amount of factual materials with educational content have been collected and three most common groups of EER have been identified: video-, text- and visual materials. It was found that some types of digital educational content, such as mind maps, animation, educational video games, stop motion videos, computer simulators etc., are almost not presented on the websites of the University libraries although they have significant potential for the modern educational process. The relevance of libraries' EER to the development trends in the digital services of online education is analyzed. The directions in EER development, requiring the attention of library specialists, are determined as follows: modernization of terminology and classification of EER; their verification; the enhancement of the professional competence of employees for improvement of the quality of educational materials; collaboration with the providers of tools and resources for creating educational materials.

Authors: Zub A. A. , Gayvoronskaya T. V. , Muratova A. Yu. , Arutyunov A. V.
Published: December 2022

Background. The prevalence of inflammatory-destructive periodontal diseases remains to be a global problem. Long-term topical application of chlorhexidine bigluconate and metronidazole is known to involve various side effects, thereby requiring widening the spectrum of herbal preparations used for treating chronic periodontitis.

Aim. To evaluate the efficacy of Chlorophyllipt in the treatment of chronic generalized periodontitis by studying cytokine concentration dynamics in the gingival fluid.

Methods. A randomized controlled clinical study of outcomes achieved in 50 patients with chronic generalized periodontitis treated in Dental Polyclinic No. 3, Krasnodar Кrai, was carried out. The control group included 20 clinically healthy people. Patients diagnosed with chronic generalized periodontitis were divided into the main (n = 25) and comparison (n = 25) groups. The main group received basic therapy and conventional conservative treatment with the addition of Chlorophyllipt. The comparison group received basic therapy and conventional conservative treatment. The therapy efficacy was estimated based on clinical indicators and IL-1β, IL-1Ra, IL-8, and TNF-α cytokine levels in the gingival fluid before treatment and after 14 days, three days, and six months of treatment. Statistical analysis was performed using the SPSS version 15 software (USA).

Results. All clinical parameters improved significantly in both chronic periodontitis groups after 14 days, three days, and six months of treatment in comparison with their levels before treatment (p < 0.001). At the same time, the conventional conservative treatment with the addition of Chlorophyllipt reduced inflammatory processes in periodontal tissues and gum bleeding at earlier stages. In the main group IL-1β, cytokine levels after 14 days of treatment were 19% lower than in the comparison group (p = 0.025), while IL-1Ra cytokine levels were 52% higher (p = 0.023). Six months after treatment, IL-1β and TNF-α cytokine levels were 14% and 32% lower than in the control group, respectively (p2 = 0.021 and p2 = 0.008), while IL-1Ra cytokine levels were 39% higher (p =0.019). All these results were statistically significant.

Conclusion. Due to the established clinical and immunological efficacy, Chlorophyllipt can   be included in the conventional conservative therapy of chronic generalized periodontitis. The determined levels of IL-1β, IL-1Ra, and TNF-α cytokines in chronic periodontitis patients can be used when assessing the response of periodontal tissues towards therapeutic interventions.

Published: December 2022

Objective:

The novel coronavirus (n COVID-19) has affected every walk of life across the world including India. Several studies have been available on the COVID-19-related anxiety and depressive symptoms in the public health context. However, there is a dearth of evidence of a meta-analysis regarding the pooled estimates of anxiety and depressive symptoms related to this pandemic based on the existing studies conducted among the general population of India. The aim of the study was to estimate the pooled prevalence of COVID-19-related anxiety and depressive symptoms among the general population in India.

Material and Methods:

We searched the following electronic bibliographic databases: PubMed, Ovid, Science Direct, and Wiley online library for studies conducted from the onset of the COVID-19 pandemic and until September 25, 2021. We separately analyzed the outcome measures based on the risk of bias assessment. The publication bias was evaluated by funnel plots and Egger’s test.

Results:

We used a random-effect model due to the significant heterogeneity between the studies (Anxiety symptoms – I2 = 99.40% and Depressive symptoms – I2 = 95.3%). According to the index meta-analysis, the pooled estimates of anxiety and depressive symptoms among general population of India during COVID-19 pandemic are 23.5% (95% CI: 17.4–29.6%; n = 21 studies) and 20.2% (95% CI: 17.2–23.2%; n = 17 studies), respectively. In subgroup analyses, good-quality studies (Score ≥7/9) had a significant effect on the pooled prevalence.

Conclusion:

About one-fifth of the general population of India reported having anxiety and depressive symptoms during the COVID-19 pandemic. The pooled estimates varied with the methodological quality of included studies. The present study provides a comprehensive picture of the overall magnitude of anxiety and depressive symptoms due to the COVID-19 outbreak which will guide the policy makers to measure the burden of similar pandemics more judiciously in the future.
Handmade models for aneurysm surgery: A useful tool for training
Authors: Sharma Vikrant , Garg Mayank , Bhaskar Suryanarayanan , Tiwari Sarbesh , Bhatia Pradeep Kumar , Jha Deepak Kumar
Published: December 2022

Background:

Aneurysm surgery is considered difficult by young and trainee neurosurgeons. This is due to difficulty in understanding orientation of aneurysm complex (proximal and distal vessels, aneurysm neck, and fundus) in relation to the surrounding structures (skull, brain, vessels, and nerves) after head is rotated, extended, and fixed on the head frame. Virtual three-dimensional (3D) imaging studies and 3D-printed models help young neurosurgeons but are not accessible to most of the centers due to need for resources (human and equipment). Authors used handmade 3D models of aneurysm complex to train young neurosurgeons before and during surgery to make them understand steps to treat it.

Methods:

RadiAnt DICOM viewer software (2022.1.1, 64-bit, Medixant, Poznan, Poland) was used for acquiring 3D Volume Rendering Technique images to make aneurysm models preoperatively. Twisted 20 Gauze galvanized iron wires were used for making proximal and distal branches and Epoxy Putty (M-seal, Pidilite® industries, Mumbai, India) was used to make smooth surfaces of the vessels, aneurysm necks, and fundi. Models were used in operating room (OR) before and during surgery to help surgeons and trainees get oriented to the aneurysm complexes.

Results:

Handmade models, oriented as per patients’ head position, were useful to make surgeons and trainees to understand projection of various components of the aneurysm complex in relation to adjacent structures, especially skull base, during both preoperative planning and in OR even before completion of the dissection.

Conclusion:

Handmade models of aneurysms are inexpensive tool and can help trainee neurosurgeons to plan and execute surgical management of aneurysms.
Oxy-reductive C-N bond formation via pulsed electrolysis
Authors: Zhang Yuxuan , Al-Mahayni Hasan , Aguiar Pedro , Chartrand Daniel , McKee Morgan , Seifitokaldani Ali , Kornienko Nikolay
Published: December 2022

Co-electrolysis of CO2 with simple N-species is an appealing route to sustainable fabrication of C-N bond containing products. A prominent challenge in, the area is to promote the C-N coupling step in place of the established CO2 reduction pathways. This can be particularly difficult when relying on solution-based species (e.g., NH3) to intercept intermediates that are continually being reduced on heterogeneous catalyst surfaces. In light of this, we introduce pulsed electrocatalysis as a tool for C-N bond formation. The reaction routes opened through this method involve both partial reduction and partial oxidation of separate reactants on the same catalyst surface in parallel to co-adsorb their activated intermediates proximal to one another. Using the CO2 and NH3 as model reactants, the end result is an enhancement of selectivity and formation rates for C-N bond containing products (urea, formamide, acetamide, methylamine) by factors of 3-20 as compared to static electrolysis in otherwise identical conditions. An array of operando measurements and computational modelling was carried out to pinpoint the key factors behind this performance enhancement. Finally, the oxy-reductive coupling strategy was extended to additional carbon and nitrogen reactants as well as applied to boost electrochemical C-S coupling.
Fully Wood-Based Transparent Plates with High Strength, Flame Self-Extinction, and Anisotropic Thermal Conduction

Published: December 2022

Glasses and transparent plastics are used as daylighting face materials in buildings and vehicles. However, these transparent materials are mechanically inferior to other structural members such as metals, concretes, and fiber-reinforced plastics, and have no contribution to the load-bearing capacities of whole structures incorporating them. Herein, we report clearly transparent and mechanically strong plate materials (haze 8%, strength 256 MPa) comprising solely wood-derived cellulose nanofibers (CNFs) with carboxy functionality. These plates have a millimeter-thick laminated structure and are united by self-adhesive forces of the CNFs. Their strength is comparable to those of light-weight structural materials, such as aluminum alloys and glass fiber-reinforced plastics, while the CNF plates are even lighter. The plates feature excellent flame self-extinguishing properties due to the carboxylate structure of CNFs and further show anisotropic thermal conduction between the in-plane and out-of-plane directions. A strategy for overcoming the high water absorption, a major issue of CNF materials, through the counterion design of carboxy groups is also demonstrated.
Rapid Adsorption Enthalpy Surface Sampling (RAESS) to Characterize Nanoporous Materials
Authors: Ren Emmanuel , Coudert François-Xavier
Published: December 2022

Molecular adsorption in nanoporous materials has many large-scale industrial applications ranging from separation to storage. To design the best materials, computational simulations are key in guiding the experimentation and engineering processes. Because nanoporous materials exist in a plethora of forms, we need to speed up the existing simulation tools to be able to screen databases of hundreds of thousands structures. Here, we describe a new algorithm that quickly calculates adsorption enthalpies by sampling the surface of the material instead of the whole porous space. This surface sampling has been tested on the CoRE MOF 2019 database and has been proven to be more than 2 orders of magnitude faster than the gold standard method (Widom insertion), with an acceptable level of error on the enthalpy value of 0.34 kJ/mol, and is therefore proposed as a valuable addition to the high-throughput screening toolbox.
Oral health concerns in elderly: A review
Authors: Umar Farooq Mohd. , P. Puranik Manjunath , K.R Soumya
Published: December 2022

Oral health is not separate from general health but maintaining oral health is definitely difficult and different in old age. Even though few elderly people have physical andor mental situation that call for particular interest in the dental workplace one should not presume that all elderly community shares these circumstances. In order to achieve health it is necessary to know few aspects of old age. In due course of old age body tissues get harder collection of waste products in body cells and loss of lubrication leads to impaired functions of various organs. There is wide evidence that periodontitis is a risk factor for certain systemic diseases and impaired oral health has been associated with mastication and nutritional problems especially among the elderly with highly negative effects on their quality of life. Although a specific protocol must be tailored to meet the unique needs of the individual patient there are certain factors common to elderly segment of the population that may influence these protocols.
Ectopic CH60 mediates HAPLN1-induced cell survival signaling in multiple myeloma

Published: December 2022

Multiple myeloma (MM), the second most common hematological malignancy, is generally considered incurable because of the development of drug resistance. We previously reported that hyaluronan and proteoglycan link protein 1 (HAPLN1) produced by stromal cells induces activation of NF-κB, a tumor-supportive transcription factor, and promotes drug resistance in MM cells. However, the identity of the cell surface receptor that detects HAPLN1 and thereby engenders pro-tumorigenic signaling in MM cells remains unknown. Here, we performed an unbiased cell surface biotinylation assay and identified chaperonin 60 (CH60) as the direct binding partner of HAPLN1 on MM cells. Cell surface CH60 specifically interacted with TLR4 to evoke HAPLN1-induced NF-κB signaling, transcription of anti-apoptotic genes, and drug resistance in MM cells. Collectively, our findings identify a cell surface CH60-TLR4 complex as a HAPLN1 receptor and a potential molecular target to overcome drug resistance in MM cells.

Neutrophils are vital in defence against pathogens, but excessive neutrophil activity can lead to tissue damage and promote acute respiratory distress syndrome. COVID-19 is associated with systemic expansion of immature neutrophils, but the functional consequences of this shift to immaturity are not understood. We used flow cytometry to investigate activity and phenotypic diversity of circulating neutrophils in acute and convalescent COVID-19 patients. First, we demonstrate hyperactivation of immature CD10−subpopulations in severe disease, with elevated markers of secondary granule release. Partially activated immature neutrophils were detectable 12 wk post-hospitalisation, indicating long term myeloid dysregulation in convalescent COVID-19 patients. Second, we demonstrate that neutrophils from moderately ill patients down-regulate the chemokine receptor CXCR2, whereas neutrophils from severely ill individuals fail to do so, suggesting an altered ability for organ trafficking and a potential mechanism for induction of disease tolerance. CD10−and CXCR2hineutrophil subpopulations were enriched in severe disease and may represent prognostic biomarkers for the identification of individuals at high risk of progressing to severe COVID-19.

Published: December 2022

Penelitian ini bertujuan untuk mengetahui pengaruh likuiditas dan kebijakan hutang terhadap nilai perusahaan dengan kinerja perusahaan sebagai variabel intervening. Obyek penelitian terdiri dari 24 perusahaan sektor property dan real estate yang terdaftar di Bursa Efek Indonesia tahun 2016-2020 dengan jumlah sampel 98 secara purposive sampling. Teknik analisis yang digunakan adalah analisis jalur dengan regresi dan dilakukan uji asumsi klasik terlebih dahulu.Pengujian variabel intervening digunakan strategi causal step dan tes sobel. Hasil analisis data menyimpulkan bahwa likuiditas yang diproksikan CR tidak signfikan, baik terhadap kinerja perusahaan maupun nilai perusahaan. Namun, berbeda dengan faktor kebijakan hutang yang diproksikan DER justru berpengaruh signfikan, baik terhadap kinerja perusahaan maupun nilai perusahaan. Sedangkan, kinerja perusahaan yang diproksikan ROA berpengaruh signifikan terhadap nilai perusahaan. Berdasarkan pada tes sobel diperoleh hasil bahwa kinerja perusahaan tidak dapat memediasi, baik hubungan likuiditas dengan nilai perusahaan maupun hubungan kebijakan hutang dengan nilai perusahaan.

The research object consists of 24 property and real estate sector companies listed on the Indonesia Stock Exchange in 2016-2020 with a total sample of 98 by purposive sampling. The analytical technique used is path analysis with regression and the classical assumption test is performed first. Testing the intervening variables used the causal step strategy and the Sobel test. The results of data analysis conclude that the liquidity proxied by CR is not significant, both on company performance and company value. However, in contrast to the debt policy factor that is proxied by DER, it has a significant effect, both on company performance and company value. Meanwhile, the company's performance as proxied by ROA has a significant effect on firm value. Based on the Sobel test, the results show that the company's performance cannot mediate, both the relationship between liquidity and firm value and the relationship between debt policy and firm value.
Nexus free cash flow dan kebijakan dividen
Authors: Nastiti Pambayun Kinasih Yekti
Published: December 2022

Kebijakan dividen dan determinannya tetap menjadi isu kontroversial dalam literatur keuangan. Tujuan studi ini untuk menguji pengaruh langsung free cash flow terhadap dividen dan pengaruh tidak langsung free cash flow terhadap dividen melalui pertumbuhan perusahaan dan leverage. Sampel studi ini adalah 32 perusahaan manufaktur yang terdaftar di Bursa Efek Indonesia selama periode 2016-2020. Analisis data   memanfaatkan regresi data panel fixed effect robustness dengan   melibatkan 160 obeservasi. Hasil penelitian menunjukkan bahwa free cash flow terbukti secara signifikan berpengaruh positif terhadap dividen. Lebih lanjut, penelitian ini mampu membuktikan adanya pengaruh free cash flow terhadap leverage yang kemudian dilanjutkan dengan leverage berimplikasi pada pembayaran dividen perusahaan. Namun, pertumbuhan perusahaan tidak terbukti dipengaruhi free cash flow dan juga tidak mempengaruhi dividen sehingga tidak mampu berperan memediasi pengaruh free cash flow terhadap dividen.       Penelitian ini secara akademis berkontribusi dalam mengintegrasikan variabel-variabel kunci determinan kebijakan dividen yang selama ini hanya diteliti secara terpisah. Sementara secara praktis, studi ini menyarankan bahwa bagi investor yang berorentasi pada dividen hendaknya mempertimbangkan   ketersedian free cash flow dan ratio hutang perusahaan.

Dividend policy and its determinants remain a controversial issue in the financial literature. This study aims to examine the direct effect of free cash flow on dividends and the indirect impact of free cash flow on dividends through firm growth and leverage. The sample of this study is 32 manufacturing firms listed on the Indonesia Stock Exchange during the 2016-2020 period. The data analysis employs fixed effect robustness panel data regression involving 160 observations.   The results study showed that the free cash flow significantly positive affects dividends. Furthermore, this study can prove the effect of free cash flow on leverage and then leverage impacts on company s dividend payments. However, the firm's growth was not proven to be influenced by free cash flow and also did not affect dividends so it was not able to play a role in mediating the effect of free cash flow on dividends. This research academically contributes to integrating the key determinants of dividend policy, which have only been studied separately so far. Practically, this study suggests that dividend-oriented investors should consider the availability of free cash flow and the firm's debt ratio.

Methods: Available cancer registry data for 1979–2016 were retrieved for the GCC countries. Age-standardized rates (ASRs) per 100 000 women were calculated using the World standard population. Comparisons were made by calculating comparative incidence figures. Results: From 1998 to 2012, incidence among nationals was highest in Bahrain (ASR 61.85), Kuwait (ASR 52.66), and Qatar (ASR 56.90) and lowest in Saudi Arabia (ASR 19.76), Oman (ASR 22.33), and United Arab Emirates (ASR 31.05). In the most recent period, data were available only in Qatar (2014–2016) and Saudi Arabia (2013–2015). Non-nationals and nationals in Qatar had higher incidence rates than in Saudi Arabia. Incidence among nationals in Qatar was at least twice that in Saudi Arabia (comparative incidence figure 2.32). Incidence among non-nationals in Qatar was 3 times higher than in Saudi Arabia. Among nationals in Kuwait, 10.8% of cases of breast cancer occurred in women aged < 40 years in 2008–2012, compared with 24.2% in non-nationals in Qatar in 2014–2016. Conclusion: Breast cancer incidence has increased over time among women in most GCC countries, likely reflecting the improvements in healthcare access and screening programmes. Nationals and non-nationals developed breast cancer at a younger age than women in other high-income countries. Increased screening uptake is still required in the region. Evidence-based, locally-informed interventions should be implemented to address risk factors specific to the nationals and non-nationals in the GCC countries.
Synchronic Analysis of the Progressive Aspect in Three Varieties of Asian Englishes
Authors: Salles-Bernal Soluna
Published: December 2022

The purpose of this study is to analyse the frequency of use of the progressive aspect in three varieties of Asian Englishes, namely Hong Kong, India and Singapore, considering British English as a point of departure. The use of the progressive will be researched in comparable corpora (International Corpus of English) considering its distribution in the English verbal paradigm and subject person, both in the written and spoken components. Main results indicate that IndE has the highest frequency of the progressive, and Hong Kong English the lowest, when non-native varieties are compared. In all cases, the progressive is more frequent in the spoken than in the written section, and it preferably occurs in the present simple tense. English varieties present significant differences regarding the distribution of the progressive by tense and subject person. Several factors are discussed as possible reasons for such variation.
Investigation of bi-layered ZnO-Ni photocatalyst powder produced by reactive magnetron sputtering technique
Authors: Lelis M.
Published: December 2022

The goal of the current study was to produce magnetic photocatalyst powder consisting of bi-layered ZnO-Ni particles for easy manipulation and collection during the repetitive photocatalytic water treatments. First, magnetron sputtering was used to cover NaCl grains by Ni underlayer and ZnO overlayer. Then the salt was washed off with distilled water. SEM, EDS and XRD analysis confirmed that obtained particles can be characterized as bi-layered open shells with nanocrystalline ZnO phase on one side and metallic Ni on the other side. In laboratory tests larger part of initial bi-layered powder were successfully recollected by magnets even after 10 consecutive usage cycles. Measurements of photocatalytic performance demonstrated relatively high activity and stability of bi-layered ZnO-Ni powder. Photocatalytic treatment of S. Typhimurium bacteria with ZnO-Ni powder and UV light in 1 hour reduced S. Typhimurium viability by more than 98 %, but similar treatment using visible light was not efficient.
Triboscopic Insights into Long-Term Tribologic Behavior of Brass/ta-C in High Vacuum
Authors: Härtwig Fabian
Published: December 2022

It is widely known that tribological systems operating in vacuum environments face significant challenges. MoS2 is a well-known material for its low friction properties in both ambient and vacuum environments. However, it has a low wear resistance and a limited ability to withstand higher contact pressures. A possible alternative to MoS2 are super-hard hydrogen-free tetrahedral amorphous carbon coatings (ta-C). In normal atmospheric conditions, they have low friction and wear properties, but their performance in vacuum is limited. In this work, ta-C coatings are paired with brass in high vacuum conditions. Long-term tribological performance tests are conducted and analyzed using triboscopic imaging. It was found that the brass/ta-C friction pair exhibited an increase of the friction coefficient in the long term (up to 0.52) due to a change in wear mechanism. Different wear and healing behaviors could be found for both the brass counterbody and the ta-C discs using triboscopy.
Framing Injustice: Special Anti-Robbery Squads (SARS) in Nigeria and the #EndSARS Protest Response from a Social Movement Theory Perspective
Authors: Omeni Akali
Published: December 2022

This article employs Social Movement Theory (SMT) to examine collective action mobilisation against malfeasance by Nigeria’s Special Anti-Robbery Squads (SARS). Created in the 1990s to counter armed gangs, SARS gradually became discredited. Finally, in October 2020, after weeks of public protest, the unit was disbanded. The #EndSARS movement proved instrumental here. The present article explores the origins, nature and decline of SARS until the #EndSARS protests. #EndSARS arguably provoked police reform in Nigeria. Furthermore, whereas social media has dominated the discourse on the protesters’ agency, I employ framing theory, as a SMT sub-set, to show that #EndSARS employed diagnostic, prognostic and motivational frames, within “injustice” master frames, towards collective action mobilisation. In conducting this analysis, I situate the #EndSARS case within the broader literature debate on impactful protests against police brutality.
African Philosophy Post 1994: In Conversation with Alena Rettova
Authors: Negedu Isaiah , Aihiokhai SimonMary Asese
Published: December 2022

The present article aims to initiate a conversation with Alena Rettová on her article “Post-Genocide, Post-Apartheid: The Shifting Landscapes of African Philosophy, 1994-2019” that was published in Modern Africa in the Summer of 2021. We identify several issues in her historical account of African philosophical thoughts that need polyphonic engagement in order to ensure that Africa’s pluralistic intellectual heritage is not reduced to a monophonic one. We are intentional at being Rettová’s intellectual dialogical partner on the reading of African philosophy, while bearing in mind that the ideologies of apartheid and genocide are still active. While we explore some key aspects of her work, we also acknowledge that African philosophy is constantly in the making and it would be problematic to use the yardstick of one context, in this case, the Western context, as a benchmark in order to account for the progression of philosophical thoughts in other philosophical contexts (Africa) without taking into account the historical peculiarities of each context.

Smartphone is widely used around the world. It’s user authentication usually used pin code, pattern code, fingerprint and conventional login authentication. This kinds of authentication mechanism is intrusive because those mechanisms requires users to give exclusive interaction for user authentication during the process. One of authentication method which is non-intrusive during data collection is authentication by using gait. This mechanism classified as non-intrusive because this mechanism could gather biometric data without being noticed by the authentication subjects. Since it is non-intrusive, this mechanism allows re-authentications without bothering the authentication subjects. One of the recent gait recognition is using accelerometer on smartphone to measure and capture acceleration data on gait. This method extract step cycles in various length, map and interpolate the data into higher sample count, and then use each of mapped and interpolated data as feature using recognition. Regardless the classification or recognition method, using each mapped and interpolated data as features would result in high processing time during classification or recognition due to high feature count. In this research, we try to simplify the features of gait data with minimum data loss so it might give robust result with less latency by aligning cubic Bezier curve to step cycle data and extracting the Bezier properties.
