Published: January 2022

Objectives to compare speech perception in a quiet and noisy environment using a basic audio coding strategy (CIS) and a modern strategy (ACE) over a period of 24 months.
Material and methods. The study involved 30 patients who received hearing rehabilitation in the National Medical Research Center for Otorhinolaryngology of the Federal Medico-Biological Agency in the period of 2018 2021. The inclusion criteria were: implantation in the adult age (from 18 to 45 years), speaking fluent Russian, hearing loss after speech skills formation. After initialization and programming of the speech processor, the patients underwent speech audiometry in a free sound field using syllabic and speech tables in silence and noise. The results were collected in the special MS Excel templates and subjected to statistical analysis.
Results. The intelligibility of syllables in patients with CIS and ACE strategies took comparable values and grew with experience within 24 months (from 52 7.00% at the beginning of the study to 72 7.25% at the end), the greatest increase in intelligibility was noted in the first 3 months after connecting the speech processor (from 52 7.00% to 66 7.87%). Using the Greenberg speech table in silence, the groups with the CIS strategy and the ACE strategy obtained similar results with a slight advantage of the ACE strategy up to 6 months of the study. Later, a significantly higher increase in speech perception was observed in the group with the ACE strategy compared to the group with CIS. After 12 months, the perception tests showed 67 8.62% in patients with CIS strategy and 71 7.54% in patients with ACE, after 24 months the results were 68 9.12%, and 72 8.62% respectively. Under noise conditions, we observed an increase of the difference between groups starting from 6 months (41 5.33% in patients with CIS versus 43.3 7.55% with ACE), the largest difference was registered after 24 months (51 5.50% versus 57 8.25% respectively).
Conclusion. When compared to the basic strategy, a modern sound coding strategy with a higher resolution can improve speech perception especially with complex speech patterns and in a noisy environment.

Published: January 2022

Objectives to analyze the number and sum of diameters of microgliocytes in the precentral gyrus cortex and the corpus callosum of a person in the early adulthood and of an old person and to identify the patterns of neurofilaments expression in these parts of the brain.
Material and methods. The results of a sectional study of the cerebral cortex in the precentral gyrus and corpus callosum using hematoxylin and eosin staining were analyzed, and an immunohistochemical study was performed using antibodies to neurofilaments. The dead were divided into two groups depending on their age. The group I included 23 men and 27 women in their early adulthood, aged from 23 to 28 years; the group II included 19 men and 25 women of the old age from 75 to 83 years. We examined the number of microgliocytes, the sum of their diameters, and the expression of neurofilament proteins in the tissue.
Results. Morphometric study of autopsy material showed that in the corpus callosum, as well as in the cortex of the precentral gyrus, there was an age-related statistically significant increase in the number of microgliocytes and the sum of their diameters (p 0.001). We found that the expression of neurofilaments in the cortex of the precentral gyrus is uniform both in the early adulthood and in old age. In the corpus callosum tissue, the age-related neurodegenerative changes are more pronounced: by old age, there is a significant decrease in the expression of neurofilaments with the formation of their rarefaction sites in the areas of microgliocyte clusters.
Conclusion. The results of morphological study of the precentral gyrus cortex and corpus callosum of two age groups testify that the number and sum of diameters of microgliocytes responsible for the utilization of spent myelin have a certain relationship with age and expression of neurofilaments in the nervous tissue.

Authors: Bazira Kanat Kyzy
Published: January 2022

Objectives assessment of adherence to treatment in elderly patients with nonvalvular atrial fibrillation who were prescribed anticoagulant therapy with vitamin K antagonist, warfarin, and a new oral anticoagulant rivaroxaban.
Material and methods. During the study, 322 patients with atrial fibrillation of nonvalvular etiology were observed. Depending on the type of anticoagulant taken, the patients were divided into 2 groups: the first group included 253 (78.6%) people who took warfarin, the second group 69 (21.4%) people, who were prescribed a new oral anticoagulant rivaroxaban.
Results. By the end of the one-year follow-up from the start of anticoagulant treatment, only 8.7% of patients in the first group followed the doctor's prescription; the second group had 59.4% of adherent patients. The vast majority of patients refused warfarin therapy due to the inability to control INR. In the case of the appointment of rivaroxaban, the reason for the refusal to take was the high cost of the drugs.
Conclusion. Effective prevention of thromboembolic complications in atrial fibrillation requires the development of appropriate measures to improve adherence to treatment.

Objectives to evaluate the association between essential chemical element levels in whole blood and in pathologic mucosa and chronic rhinosinusitis severity in children.
Material and methods. A total of 154 children aged from 6 to 17 years were examined. Among them, 88 children had chronic rhinosinusitis (CRS) and underwent functional endoscopic sinus surgery (FESS). The 66 healthy children were included in the control group. Life quality was assessed using SNOT-20 (Sino-Nasal Outcome Test-20). Endoscopic and computer tomography findings were evaluated using Lund Kennedy and Lund Mackay scales, respectively. The assessment of essential element levels in whole blood samples was performed using inductively-coupled plasma mass-spectrometry.
Results. The obtained data demonstrate that total SNOT-20 scores in CRS patients were 68% higher than in controls. At the same time, whole blood calcium, selenium, zinc, and magnesium levels were 6%, 28%, 20%, and 3% lower than the respective control values. The analysis of pathologic mucosa demonstrated that the chemical element contents were reducing in the following order: Ca Mg = Fe Zn Cu Mn Se. However, only whole blood selenium level correlated significantly with its tissue level. In multiple regression models, the whole blood Se level was inversely associated with SNOT-20 and Lund Mackay total scores.
Conclusion. Therefore, the obtained data allow to propose the potential role of altered calcium, magnesium, zinc and selenium metabolism in CRS progression.

Published: January 2022

The effects of reactive gas flow conditions on nonpolar AlN film growth on MnS/Si (100) substrates using reactive DC magnetron sputtering were investigated. During AlN deposition at a substrate temperature of 750 °C, the MnS surface can be unintentionally nitrided, resulting in a decrease in the crystallinity of the AlN. Low-temperature growth of the AlN layer at 300 °C prevents this nitridation and results in the crystallization of nonpolar AlN. A N2 flow equal to 30% of the Ar sputtering gas flow was found to improve the crystallinity of the nonpolar AlN and to reduce nitrogen defects, which play an important role in interfacial reactions. Nitrogen defects promote the formation of alloys such as AlMn and MnSi that degrade the interface and can significantly decompose the MnS. A higher proportion of N2 improves the nonpolar AlN crystallinity, reduces the concentration of defects and suppresses reactions at the AlN/MnS interface.

Published: January 2022

We characterized CVD-grown graphene with high single-crystallinity on Ir(111)/α-Al2O3(0001) by photoelectron momentum microscopy. A multi-functional photoelectron momentum microscope (PMM), which is installed with element-specific valence band photoelectron spectroscopy and X-ray absorption spectroscopy, is a complementary characterization tool to conventional methods, such as Raman spectroscopy and atomic force microscopy, for comprehensive and quantitative characterization of graphene/Ir(111). Using PMM, we characterized the properties of CVD-grown graphene including the single-crystallinity, number of layers, crystal orientation, and degree of interaction between graphene and Ir(111) and clarified the relationship between these properties and the CVD growth conditions.

Published: January 2022

This study explores the rigidity of Pickering-stabilised microbubbles subjected to low-amplitude ultrasound. Such microbubbles might be suitable ultrasound contrast agents. Using an adapted Rayleigh–Plesset equation, we modelled the dynamics of microbubbles with a 7.6-N m−1 shell stiffness under 1-MHz, 0.2-MPa sonication. Such dynamics were observed experimentally, too, using high-speed photography. The maximum expansions were agreeing with those predicted for Pickering-stabilised microbubbles. Subjecting microbubbles to multiple time-delayed pulses yielded the same result. We conclude that Pickering-stabilised microbubbles remain very stable at low acoustic amplitudes.
STUDY TEORI MUTUALISME PAUL F. KNITTER DALAM HUBUNGAN ANTARUMAT BERAGAMA DI INDONESIA
Authors: Waluyo Waluyo , Abidin Sahal
Published: January 2022

Agama merupakan peratuan yang dibuat oleh Tuhan, melalui perantara-Nya disampaikan kepada setiap manusia. Dalam perjalannannya agama menjadi way of live pada setiap pemeluknya. Selain itu agama menjadi pegangan yang tidak dapat diganggu gugat oleh orang lain. Kenyakinan dalam kebenaran agamanya semakin mengakar dan menyebabkan truth claim. Klaim kebenaaran dan penolakan kebenaran yang lain adalah implementasinya. Adanya klaim kebenaran dan berusaha menyelamatkan yang lain dari kesesatan merupakan misioner. Fenomenologi menjawab konflik antaragama didasari atas ketikadilan kesejahteraan dan kesenjangan sosial serta keinginan kesataraan politik. Husserl melalui fenomenologinya memberikan pengertian bahwa ada kebenaran dibalik sesuatu yang tampak. Fenomenologi menangkap bahwa konflik antaragama tidak sepenuhnya disebabkan perbedaan agama. Selain klaim kebenaran dan keselamatan ketidakadilan di bidang ekonomi, politik, sosial dan budaya merupakan sumber dari konflik. Konflik yang terjadi semakin besar karena adanya klaim yang menyundut konflik antaragama, sehingga setiap pemeluk agama akan merasa terusik. Mutualisme memberikan teori hubungan antaragama yang dialog mutual. Teori ini atas dasar pandangan orang Kristen melahat agama di luar gereja. Berdasar kesamaan yang ada pada setiap agama mutualisme memproyeksikan hubungan yang saling memnguntungkan. Latar belakang konflik ialah adanya ketidakadilan pada bidang politik, ekonomi dan budaya, maka tawaran Knitter yang dapat diterapkan di Indonesia adalah pola hubungan yang mutual.

Introduction. Verification of histological changes in respiratory system using Syrian (golden) hamsters (Mesocricetus auratus) as experimental model is an important task for preclinical studies of drugs intended for prevention and treatment of the novel coronavirus infection COVID-19.The aim of this work was to study pathological changes of pulmonary tissue in SARS-CoV-2 (Coronaviridae: Coronavirinae: Betacoronavirus; Sarbecovirus) experimental infection in Syrian hamsters. Material and methods. Male Syrian hamsters weighting 80–100 g were infected by intranasal administration of culture SARS-CoV-2 at dose 4 × 104 TCID50/ml (TCID is tissue culture infectious dose). Animals were euthanatized on 3, 7 and 14 days after infection, with gravimetric registration. The viral load in lungs was measured using the polymerase chain reaction (PCR). Right lung and trachea tissues were stained with hematoxylin-eosin and according to Mallory.Results and discussion. The highest viral replicative activity in lungs was determined 3 days after the infection. After 7 days, on a background of the decrease of the viral load in lungs, a pathologically significant increase of the organ’s gravimetric parameters was observed. Within 3 to 14 days post-infection, the lung histologic pattern had been showing the development of inflammation with a succession of infiltrative-proliferative, edematousmacrophagal and fibroblastic changes. It was found that initial changes in respiratory epithelium can proceed without paranecrotic interstitial inflammation, while in the formation of multiple lung parenchyma lesions, damage to the epithelium of bronchioles and acinar ducts can be secondary. The appearance of epithelioid large-cell metaplastic epithelium, forming pseudoacinar structures, was noted as a pathomorphological feature specific to SARS-CoV-2 infection in Syrian hamsters.Conclusion. As a result of the study, the specific features of the pathology of the respiratory system in SARSCoV-2 infected Syrian hamsters were described. These findings are of practical importance as reference data that can be used for preclinical studies to assess the effectiveness of vaccines and potential drugs.

Introduction. Tat protein is a major factor of HIV (human immunodeficiency virus) transcription regulation and has other activities. Tat is characterized by high variability, with some amino acid substitutions, including subtypespecific ones, being able to influence on its functionality. HIV type 1 (HIV-1) sub-subtype A6 is the most widespread in Russia. Previous studies of the polymorphisms in structural regions of the A6 variant have shown numerous characteristic features; however, Tat polymorphism in A6 has not been studied.Goals and tasks. The main goal of the work was to analyze the characteristics of Tat protein in HIV-1 A6 variant, that is, to identify substitutions characteristic for A6 and A1 variants, as well as to compare the frequency of mutations in functionally significant domains in sub-subtype A6 and subtype B.Material and methods. The nucleotide sequences of HIV-1 sub-subtypes A6, A1, A2, A3, A4, subtype B and the reference nucleotide sequence were obtained from the Los Alamos international database.Results and discussion. Q54H and Q60H were identified as characteristic substitutions. Essential differences in natural polymorphisms between sub-subtypes A6 and A1 have been demonstrated. In the CPP-region, there were detected mutations (R53K, Q54H, Q54P, R57G) which were more common in sub-subtype A6 than in subtype B.Conclusion. Tat protein of sub-subtype A6 have some characteristics that make it possible to reliably distinguish it from other HIV-1 variants. Mutations identified in the CPP region could potentially alter the activity of Tat. The data obtained could form the basis for the drugs and vaccines development.

Justice system and juvenile deviance after the Covid-19 pandemic. Educational paths between school promotion and re-education
Authors: Guarcello Emanuela , Gozzelino Giulia
Published: January 2022

Starting from the concept of social justice and from universal children’s rights (UN, 1989), the contribution questions the role of education in enhancing the originality and uniqueness of each one and in restoring responsibility and dignity to fragile (Milani, 2019), difficult (Bertolini ,1993) and deviant (Vico, 1988) young people. In a complex contemporaneity, tested by pandemic’s sufferings and restrictions, the pedagogical look underlines the importance of reconstructing – starting from school – promotional, capacitating and justice-oriented paths. Deviant acts are read in the light of a broad social responsibility. We propose the empowerment of an educating community (Agazzi, 1968) aimed at participation, dialogue (Freire, 2002) and assumption of an active and inclusive citizenship. The juvenile penal system is collectively rethought, favouring diversion from prosecution, mediation, reparation and probation strategies.

 

Giustizia e devianza minorile dopo la pandemia Covid-19. Percorsi alternativi tra promozione scolastica e rieducazione.

 

Partendo dal concetto di giustizia sociale e dai diritti universali delle bambine, dei bambini e degli adolescenti (UN, 1989), il contributo si interroga sul ruolo dell’educazione nel valorizzare l’originalità e l’unicità di ciascuno e nel restituire responsabilità e dignità ai soggetti fragili (Milani, 2019), difficili (Bertolini, 1993) e devianti (Vico, 1988). In una contemporaneità complessa, provata dalla sofferenza e dalle restrizioni della pandemia, lo sguardo pedagogico sottolinea l’importanza di ricostruire, a partire dalla scuola, percorsi promozionali, capacitanti e orientati alla giustizia. Si rileggono gli atti devianti alla luce di un’ampia responsabilità sociale e si propone l’empowerment di una comunità educante (Agazzi, 1968) volta alla partecipazione, al dialogo (Freire, 2002) e all’assunzione di una cittadinanza attiva e inclusiva per ripensare collettivamente il sistema penale minorile privilegiando deviazioni dall’accusa, strategie di mediazione, di riparazione e di messa alla prova.

Published: January 2022

The use of crushed quarry dust as a partial replacement of river sand in concrete production was investigated in this study. This is expedient as quarry dust can be available at some locations with insufficient river sand for construction purposes. The use of quarry dust is also in concrete is also a measure necessary for improvement of concrete strength. River sand was replaced with quarry dust for different mix designs of concrete for 0% to 25% replacement levels with 5% intervals. The physical properties of river sand and quarry dust were tested and reported and the workability as well as compressive strengths of the concrete mixtures were also tested. It was observed that the slump values increased with increase in percentage replacement of sand with quarry dust. The compressive strength of cubes at 28 day curing for control mixture of 1:3:6 at 0% partial replacement of river sand with quarry dust was 12.6N/mm2 but compressive strengths of 21.5 N/mm2 and 26.0 N/mm2 were gotten for 1:2:4 concrete and 1:1.5:3 concrete respectively. As the quarry dust content increased to 25%, the 28day compressive strength increased to 13.58 N/mm2 and 21.57 N/mm2 for the 1:3:6 and 1:2:4 mixes respectively. Compressive strength values decreased to a value of 25.72N/mm2 for the 1:1.5:3 concrete mix. The maximum compressive strength values were reached at 20% quarry dust content at the age of 28 days for the three concrete grades investigated. The increase in compressive strength with inclusion of quarry dust was attributed to the higher specific gravity of quarry dust above river sand. The compressive strength of quarry dust concrete continued to increase with age for all the percentages of quarry dust contents. Quarry dust was recommended as a suitable partial replacement for river bed sand in concrete production.

The use of biochar as a low-cost adsorbent to remove nutrients from aqueous solutions is getting great attention lately due to its many environmental applications and benefits. Although, biochar has been widely used to remove phosphate from aqueous solutions, inconsistencies still exist with regards to biochar properties responsible for the adsorption process. This research was therefore, carried out to determine the influence of some biochar properties on maximum phosphate adsorption capacity of biochar produced from four different feed-stocks. The biochars used for this study were prepared from two plant materials; (Maize cob and rice husk) and two animal wastes (cow dung and poultry litter) at 600 °C. The different biochars were subjected to a laboratory batch sorption experiment. Data obtained were fitted into the linear forms of the Langmuir, Freundlich, Temkin and Dubinin-Radushkevich (D-R) adsorption isotherms while least square regression analysis was used to test the goodness of fit using the coefficient of determination (R2). Similarly, stepwise regression analysis was carried out to determine the nature and extent of relationships between the biochar properties and maximum phosphate adsorption capacity using statistical analysis software (SAS 9.4). Results revealed higher R2 values for the D-R adsorption isotherm (> 0.97) across all the treatments suggest better fit of the D-R adsorption isotherm for phosphate adsorption onto the biochar materials. The maximum phosphate adsorption capacity of the biochar materials is in the order: maize cob biochar > poultry litter biochar > cow dung biochar > rice husk biochar. Stepwise regression analysis revealed that 99 % of the change in maximum phosphate adsorption is influenced by the combined effects of biochar EC, moisture content and specific surface area. Hence, modification of biochar EC, moisture content and specific surface area is essential for improving phosphate adsorption by biochar.

هذا البحث عبارة عن استقصاء ودراسة لمن وصفهم ابن حبان بوصف (ثقة) في كتابه الثقات، الذي ضمّ بين دفّتيه عدد كبير من الرواة الذين شملهم هذا الوصف، فكان عددهم (18) راوٍ، فاقتضى أن يكون المنهج لهذا البحث بذكر قول ابن حبان في ترجمة الرواة، ثم نقل أقوال علماء الجرح والتعديل باختصار، ثم بيان خلاصة مقابلة الأقوال وذكر موافقة ابن حبان لغيره من عدمها، فاقتضت الحاجة في هذا إلى بيان مفهوم مصطلح (ثقة) عند ابن حبان وعند غيره من المحدثين، بإيجاز، ثم دراسة الرواة الذين صنفهم ابن حبان ضمن طبقة (التابعين)، ثمّ طبقة (أتباع التابعين)، ثم طبقة (تبع الأتباع)، فتبين في الختام أن ابن حبان لم يضع تعريفا دقيقا لمصطلح الثقة، وأن عدد الرواة الذين وصفهم ابن حبان بقوله: (ثقة) بلغ (18) راوٍ، أي: إن نسبتهم (50%)، وهي نسبة وإن كانت مقبولة، إلا أنها لا تتوافق مع موضوع الكتاب، وهذا يؤيد صحة ما قيل من تساهل ابن حبان في التوثيق، وإن عدد الرواة الذين وافق قول ابن حبان قول المحدثين بلغ (9) رواة. كما بلغ عدد الرواة الذين خالف المحدثين ابن حبان في توثيقهم (6) رواة، وبلغ عدد الرواة الذين انفرد ابن حبان في توثيقهم، ولم يذكرهم غيره (3) رواة.

Method for determining of the critical value of the Niyama criterion based on computational experiment is developed. It is found that the critical value of the Niyama criterion depends on the alloy cooling conditions and therefore is applicable only to the given technological process. The critical values of the Niyama criterion for casting s made of ML10 and 14Kh17N2L alloys obtained in permanent metal moulds and in moulds of coldhardening mixtures are determined. The obtained results are confirmed on shaped casting.
