Published: October 2022

All patients with chronic kidney disease (CKD) require treatment to reduce the risk of cardiovascular events and to prevent progression of renal failure. ACE inhibitors and angiotensin receptor blockers are widely used for cardio- and nephroprotection in patients with CKD. Sodium glucose cotransporter type 2 (SGLT-2) inhibitors show significant prospects for reducing morbidity and mortality in this population. SGLT-2 inhibitors have been developed for treatment of patients with type 2 diabetes mellitus. However, evidence from multiple randomized clinical trials suggested that these drugs have cardio- and nephroprotective effects in patients with and without diabetes. Despite a wealth of data, SGLT-2 inhibitors remain underused by nephrologists or cardiologists. This is not surprising since new therapies traditionally take decades from research to clinical implementation due to many barriers, including lack of knowledge, concern about drug side effects, lack of decision support, cost, and clinical inertia. The review article presents data from scientific studies on the renoprotective effect of SGLT-2 inhibitors and the mechanisms of this activity in CKD patients.

Published: October 2022

У статті розглядається реалізація навчального матеріалу з фізики під час опанування дисциплін хімічного і біологічного спрямування. Встановлено, що загальна фізика студентами нефізичних спеціальностей вивчаєть ся на перших курсах педагогічних закладів вищої освіти. У цей період вони слабо уявляють, які знання з фізики їм можуть стати в нагоді у майбутній професійній діяльності. У зв’язку з цим виникає необхідність організації занять таким чином, щоб студенти хімічних і біологічних спеціальностей вже на перших роках навчання могли зрозуміти, де та як застосовуються фізичні знання у їхній майбутній професії. У статті акцентується увага на застосуванні міждисциплінарних зв’язків під час вивчення фізики у студентів хімічного і біологічного профілю. У такому випадку використовується інтегрований підхід, який передбачає поєднання фізичного матеріалу з матеріалом хімічного і біологічного спрямування. Виходячи із цього, розробляються лекційні, практичні та лабораторні заняття, під час яких фізичні знання використовуються для вирішення хімічних та біологічних проблем і завдань. Проведено синтез навчального матеріалу з фізики, хімії і біології як вищого рівня інтеграції природничо-наукових знань, проаналізовано інтегровані заняття та запропоновано їх реалізацію на основі використання засобів мультимедіа з раціональним поєднанням традиційних методів. Наведені в роботі приклади тем інтеграційного змісту з фізики, хімії і біології допомагають формувати природничо-наукові знання студентів нефізичних спеціальностей педагогічних закладів вищої освіти. З’ясовано, що підібраний навчальний матеріал такого змісту сприяє студентам краще засвоїти фізичні явища та закони в дисциплінах хімічного та біологічного спрямування й отримати знання, які стануть у нагоді в їхній професійній діяльності.

Розглянуто актуальність отримання здобувачами вищої освіти теоретичних знань та практичних навичок під час вивчення електротехніки у вищих навчальних закладах для розрахунку складних електричних кіл, що містять декілька вузлів, віток, контурів. Такі знання необхідні спеціалістам, що працюють у галузі інформаційних технологій, енергетики, промислового виробництва або просто у повсякденному житті та можуть бути використані для правильної експлуатації різних електротехнічних установок. Зокрема, у статті проаналізовано особливості вивчення складних лінійних електричних кіл постійного струму в курсі «Електротехніка» на практичних та лабораторних заняттях. Розрахунок струмів у вітках електричного кола здійснено на основі першого та другого законів Кірхгофа. Детально розглянуто методику розрахунку для електричного кола, що містить два незалежних контури, три джерела ЕРС та три різних опори. Складені рівняння для незалежних контурів запропоновано записувати у матричному вигляді, що значно спрощує знаходження невідомих струмів. Акцентовано увагу на необхідності проведення лабораторних робіт під час вивчення електротехніки для кращого розуміння студентами нового матеріалу. Нині на ринку є можливість купити різноманітне лабораторне устаткування, але виробник, як правило, не дає методичні вказівки для проведення лабораторних робіт. Отже, виникає необхідність самостійно це робити. У зв’язку із цим обґрунтовано використання панелей «Лінійні електричні кола» вітчизняного виробника під час виконання лабораторних робіт з електротехніки для набуття практичних навичок з вивчення складних електричних кіл. Розроблено теоретичні відомості для виконання лабораторної роботи «Дослідна перевірка законів Кірхгофа», які можна ефективно використовувати на заняттях зі студентами вищих навчальних закладів. Поєднання теорії та розробленої лабораторної роботи дозволить студентам навчитися не тільки правильно проводити теоретичні розрахунки, а й складати розгалужені кола, здійснювати необхідні вимірювання, що допоможе набуттю необхідних фахових компетентностей майбутнього фахівця.

Дана стаття присвячена проблемі розвитку критичного мислення в учнів старшої школи. Актуальність проблеми підтверджується збільшенням останнім часом кількості науково-методичних публікацій з цієї теми, закріпленням словосполучення «критичне мислення» в нормативних документах, що стосуються організації освіти в Україні, появою низки дисертаційних досліджень, пов’язаних з розвитком критичного мислення засобами різних навчальних предметів. Безпосередня мета даної статті полягає в тому, щоб показати на конкретному прикладі, як знання та навички, отримані на уроках математики, інформатики і фізики, а також на заняттях гуртка закладу позашкільної освіти, можуть ставати знаряддям критичного мислення при аналізі фізичного тексту. Як приклад обрано статтю, опубліковану в науковому журналі. Новизна нашої розвідки полягає, перш за все, в тому, що нам вдалося знайти доволі вдалу для наших цілей статтю, опубліковану в науковому виданні, яка і стала предметом критичного аналізу на заняттях фізико-математичного гуртка. Унікальність цієї статті в тому, що вона дозволила старшокласникам у реальній ситуації застосувати цілу низку прийомів критичного мислення, з якими вони знайомилися на попередніх заняттях гуртка, використовуючи спеціально сконструйовані вправи. З використанням цих прийомів була проаналізована не лише кінцева формула для періоду коливань, а й одна з ключових проміжних формул. Крім того, гуртківці познайомилися з новими для них прийомами критичного мислення. Найцікавішим було те, що вдалося довести хибність самого методу, який запропонували автори аналізованої статті для виведення формули періоду коливань математичного маятника у випадку довільних амплітуд. Із проведеного дослідження ми зробили висновок, що має сенс продовжувати пошуки опублікованих фізичних текстів, які були б цікавими з точки зору використання їх як методичного матеріалу для навчання старшокласників прийомів критичного мислення на основі інтеграції знань з фізики, математики та інформатики.
La España despoblada: similitudes y diferencias territoriales
Authors: Bandrés Moliné Eduardo , Azón Puértolas Vanessa
Published: October 2022

Este artículo analiza el fenómeno de la despoblación en España acotando su dimensión temporal y geográfica, así como sus vínculos con los factores económicos que en buena parte lo determinan. La España despoblada no es, sin embargo, un todo uniforme. El análisis realizado identifica tres grupos de provincias: una España despoblada que decrece, una España despoblada que se estanca y una España despoblada que remonta. De ello deriva la necesidad de diseñar políticas adaptadas a la realidad de cada situación.
Fondo de Recuperación y Resiliencia de la UE: instrumentos y gobernanza
Authors: González Ojeda Lucas
Published: October 2022

La irrupción de la pandemia de la COVID-19 obligó a paralizar el normal funcionamiento de las economías europeas. La Unión Europea reaccionó a esa eventualidad, y a sus consecuencias económicas, de una manera singularmente rápida y efectiva y, además de otros instrumentos comunes de urgencia, acordó un mecanismo de inversión sin precedentes en su importe —en torno a los 800.000 millones de euros— y en su financiación, a través de la emisión de deuda por la Comisión Europea. El contexto de la invasión de Ucrania por parte de Rusia, supone un escollo añadido para el crecimiento económico, en un entorno de presiones inflacionistas. En ese sentido, la implantación y ejecución de los distintos planes de recuperación y resiliencia, resultan, si cabe, más importantes.
Audio Signal Processing Using Time-Frequency Approaches: Coding, Classification, Fingerprinting, and Watermarking
Authors: Umapathy Karthi , Ghoraani Behnaz , Krishnan Sridhar
Published: October 2022

Audio signals are information rich nonstationary signals that play an important role in our day-to-day communication, perception of environment, and entertainment. Due to its non-stationary nature, time- or frequency-only approaches are inadequate in analyzing these signals. A joint time-frequency (TF) approach would be a better choice to efficiently process these signals. In this digital era, compression, intelligent indexing for content-based retrieval, classification, and protection of digital audio content are few of the areas that encapsulate a majority of the audio signal processing applications. In this paper, we present a comprehensive

array of TF methodologies that successfully address applications in all of the above mentioned areas. A TF-based audio coding scheme with novel psychoacoustics model, music classification, audio classification of environmental sounds, audio fingerprinting, and audio watermarking will be presented to demonstrate the advantages of using time-frequency approaches in analyzing and extracting information from audio signals.
Discriminant non-stationary signal features’ clustering using hard and fuzzy cluster labeling
Authors: Ghoraani Behnaz , Krishnan Sridhar
Published: October 2022

Current approaches to improve the pattern recognition performance mainly focus on either extracting non-stationary

and discriminant features of each class, or employing complex and nonlinear feature classifiers. However, little

attention has been paid to the integration of these two approaches. Combining non-stationary feature analysis with

complex feature classifiers, this article presents a novel direction to enhance the discriminatory power of pattern

recognition methods. This approach, which is based on a fusion of non-stationary feature analysis with clustering

techniques, proposes an algorithm to adaptively identify the feature vectors according to their importance in

representing the patterns of discrimination. Non-stationary feature vectors are extracted using a non-stationary

method based on time–frequency distribution and non-negative matrix factorization. The clustering algorithms

including the K-means and self-organizing tree maps are utilized as unsupervised clustering methods followed by a

supervised labeling. Two labeling methods are introduced: hard and fuzzy labeling. The article covers in detail the

formulation of the proposed discriminant feature clustering method. Experiments performed with pathological

speech classification, T-wave alternans evaluation from the surface electrocardiogram, audio scene analysis, and

telemonitoring of Parkinson’s disease problems produced desirable results. The outcome demonstrates the benefits

of non-stationary feature fusion with clustering methods for complex data analysis where existing approaches do not

exhibit a high performance.

Authors: Chen Guangyi , Krishnan Sridhar , Bui Tien D.
Published: October 2022

In this letter, we study the Ramanujan Sums (RS) transform by means of matrix multiplication. The RS are orthogonal in nature and therefore offer excellent energy conservation capability. The 1-D and 2-D forward RS transforms are easy to calculate, but their inverse transforms are not defined in the literature for non-even function . We solved this problem by using matrix multiplication in this letter.
Time-Frequency Signal Synthesis and Its Application in Multimedia Watermark Detection
Authors: Krishnan Sridhar , Le Lam
Published: October 2022

We propose a novel approach to detect the watermark message embedded in images under the form of a linear frequency modulated chirp. Localization of several time-frequency distributions (TFDs) is studied for different frequency modulated signals under various noise conditions. Smoothed pseudo-Wigner-Ville distribution (SPWVD) is chosen and applied to detect and recover the corrupted image watermark bits at the receiver. The synthesized watermark message is compared with the referenced one at the transmitter as a detection evaluation scheme. The correlation coefficient between the synthesized and the referenced chirps reaches 0.9 or above for a maximum bit error rate of 15% under intentional and nonintentional attacks. The method provides satisfactory result for detection of image watermark messages modulated as chirp signal and could be a potential tool in multimedia security applications.
Relationships among COVID-19 Prevention Practices, Risk Perception and Individual Characteristics: A Temporal Analysis
Authors: Wang Lu , Yu Jie , Chen Dongmei , Yang Lixia
Published: October 2022

The effectiveness of public health measures in containing an infectious disease largely depends on how the general public is taking the prevention practices in daily lives. Previous studies have shown that different risk perceptions and sociodemographic characteristics may lead to vastly different prevention behaviors. This paper applies a temporal perspective in examining the changing patterns of prevention practices over time and their dynamic relationships with the perceived risk towards COVID-19 and its individual characteristics. Three key timelines (February, April, and June of 2020) were identified to represent the early, lockdown, and reopening stages of the first wave. Data were drawn from an online survey conducted in the Greater Toronto Area (GTA) of Canada (n = 470). Chi-square tests and logistic regression models revealed important temporal patterns in practicing different hygienic and mobility-related prevention measures and the respondents’ risk perceptions during the three timelines. The factors predicting the level of prevention practices vary across the three timelines, based on the specific type of prevention, and within the changing public health contexts. This study contributes to the literature on COVID-19 by incorporating a temporal perspective in conceptualizing prevention predictors. It provides crucial insights for developing timely public health strategies to improve infectious disease prevention at different stages and for individuals with varying backgrounds. 
Cognitive Control in Young and Older Adults: Does Mood Matter?
Authors: Truong Linda , Kandasamy Kesaan , Yang Lixia
Published: October 2022

The dual mechanisms of control framework (DMC) proposes two modes of cognitive control: proactive and reactive control. In anticipation of an interference event, young adults primarily use a more proactive control mode, whereas older adults tend to use a more reactive one during the event, due to age-related deficits in working memory. The current study aimed to examine the effects of mood induction on cognitive control mode in older (ages 65+) compared to young adults (ages 18–30) with a standard letter-cue (Experiment 1) and a modified face-cue AX-CPT (Experiment 2). Mood induction into negative and/or positive mood versus neutral mood was conducted prior to the cognitive control task. Experiment 1 replicated the typical pattern of proactive control use in young adults and reactive control use in older adults. In Experiment 2, older adults showed comparable proactive control to young adults in their response time (RT). Mood induction showed little effect on cognitive control across the two experiments. These results did not reveal consistent effects of mood (negative or positive) on cognitive control mode in young and older adults, but discovered (or demonstrated) that older adults can engage proactive control when dichotomous face cues (female or male) are used in AX-CPT. 
Evaluasi Dampak Program Intervensi di Sektor Pertanian
Authors: Ibnu Muhammad
Published: October 2022

Intervensi di sektor pertanian perlu dievaluasi apakah benar-benar berhasil dan memberikan dampak yang diharapkan kepada penerima manfaat, misalnya petani. Namun, definisi evaluasi dampak cukup beraneka ragam dalam dua dekade terakhir. Studi-studi empiris sebagian juga masih bias dalam melakukan evaluasi dampak, dan hal ini terkait dengan metode yang digunakan. Penelitian ini memiliki tiga tujuan. Pertama, meninjau kembali definisi evaluasi dampak menurut literatur. Kedua, mengidentifikasi sumber bias dalam studi evaluasi dampak. Ketiga, meninjau kembali studi-studi empiris tentang evaluasi dampak, yang memiliki hasil berbeda, terutama dari metodologi yang digunakan. Studi-studi empiris yang dijadikan ‘kasus’ di sektor pertanian adalah studi-studi tentang dampak standar dan sertifikasi kopi. Penelitian ini mengkaji literatur, baik literatur yang bersifat teoritis maupun yang bersifat empiris. Berdasarkan literatur, definisi evaluasi dampak yang paling umum adalah evaluasi yang berkaitan dengan penetapan kontra faktual, yaitu perbedaan yang dibuat oleh suatu program intervensi dibandingkan dengan bila program intervensi tersebut tidak ada. Kontra faktual yang tidak didesain dengan tepat merupakan sumber utama bias dalam evaluasi dampak, selain ancaman validitas. Berdasarkan kajian studi-studi empiris tentang dampak standar dan sertifikasi kopi, disimpulkan bahwa sebagian studi hasilnya lebih dapat dipercaya dibandingkan studi-studi yang lain. Studi-studi yang hasilnya dapat lebih dipercaya mempergunakan kontra faktual yang andal, sehingga mampu meminimalkan bias evaluasi dampak melalui perbandingan yang sesuai (apple-to-apple comparison) antara kelompok intervensi dan kelompok kontrol.

Myra’nın liman yerleşimi Andriake, kentin güneybatısında, Andriakos Çayı’nın denize döküldüğü yerde (Çayağzı) kurulmuştur. Günümüzde ise Antalya ilinin Demre ilçesi sınırlarındadır. Limanda, 2009 yılında başlayan kazı çalışmalarında çok sayıda buluntuyla karşılaşılmıştır. Bu buluntular arasında en yoğun grubu seramikler oluşturmaktadır. Çalışmanın konusu, Andriake Limanı’nda bulunan Geç Roma C Kırmızı Astarlı Seramikleridir. Phokaia’da üretilen bu grup seramiklerden Andriake’de toplam otuz dört adet ele geçmiş, bunlar üç ana form ve altı alt tipe ayrılmıştır. Hayes’in tipolojisi dikkate alınarak yapılan sınıflandırmada Hayes Form 2, 3 ve 8 ana formlar iken, Hayes Form 2A, 3B, C, D, E ve F alt tipleri oluşturmaktadır. Ana formlar arasında en yoğun grup, Form 3’e ait tabaklardır. Bu tabaklar arasındaki en yoğun alt tip ise Form 3C ve F’ye ait örneklerdir. İncelenen seramikler içerisinde kâseler Hayes Form 8’e ait tek örnekle temsil edilmektedir. Andriake’de bulunan Geç Roma C Kırmızı Astarlı Seramikleri MS 5. yüzyılın başı ile 6. yüzyılın ilk yarısına tarihlenmektedir. Yerleşimde, MS 6. yüzyılın ilk yarısından sonra bu grup seramiklerin ele geçmemesi, MS 7. yüzyılda tüm Akdeniz’i etkisi altına alan Arap akınlarının Andriake’yi de etkilemiş olmasından kaynaklanmaktadır. Limanda, Geç Roma C grubu seramiklerin yanı sıra MS 1.-3. yüzyıllara ait Phokaia üretimi tavaların da bulunması, Myra’nın limanı aracılığıyla Phokaia ile oldukça uzun yıllar (MS 1.-6. yüzyıllar arası) ticaret yaptığını göstermektedir.

Published: October 2022

Purpose. To propose a method of comparative evaluation of technical efficiency of mobile workover rig by the criterion of life cycle cost. Methodology. The proposed method is based on the determination of the specific discounted costs related to the technical condition of the machine, spent on a conventional unit of work performed. It combines economic and technical indicators that characterize the performance of the machine. This makes it possible to indirectly assess its technical efficiency. Procedures for obtaining and processing input information, analytical dependences for establishing the components of the mathematical model and its solution are shown. Findings. Using the proposed method, a comparison is performed of three conventional similar models of workover rigs, which are positioned as more reliable, and two which are less reliable and cheaper. Their indicators are formed as a weighted average based on the analysis of an array of statistical information. The obtained values were used to indirectly determine the specific discounted costs for the maintenance of rigs in working order for a period of time; the rigs are characterized by the indicator of technical efficiency. The comparison of these indicators for similar workover rigs is performed for such characteristic points as the moment of balancing of expenses, expenses for the forecasted period of operation, the periods of operation at which expenses are balanced. It is confirmed that usually the gain from the greater durability far exceeds the reduction of the economic effect of the rise in price of the machine. Originality. The proposed method for engineering forecasting of technical efficiency of technological machines using values of economic and technical indicators available to engineers of the petroleum industry. Practical value. This assessment is intended to objectively compare several analogue models and make a reasonable choice of a more efficient technological machine.

Purpose. To propose measures on assessing the initial state of the environment based on the foreign experience of natural resources protection by business structures in the extractive industry (using the example of some countries that are members of the Organization for Economic Co-operation and Development (OECD). Methodology. In the course of the scientific research, the authors used a number of general scientific and special methods of cognition, such as analysis for critical assessment of approaches to the interpretation of the essence and necessity of nature protection; quantitative and qualitative comparisons to highlight the mutual impact of environmental protection measures used by companies of OECD member countries; scientific abstraction and systematization for setting out proposals regarding the application of the most successful measures for Ukraine, applied by OECD member countries. Findings. The authors considered the experience of foreign member countries of the OECD such as Kazakhstan, Australia, Canada, the USA in terms of the implementation of some international regulations on labor protection, local maintenance standards, the governments focus on cooperation with license holders for subsoil use operations. Originality. The authors suggested that the government of Ukraine pay attention to the measures introduced by Australia in terms of assessment of the initial state of the environment. Subsoil user companies should collect environmental information at the project planning stage in order to determine the factors that are subject to monitoring, further study, and control at the stage of liquidation of consequences after the termination of operations. Environmental information should include information on climatic conditions, geological data, soil data, hydrological data, data on vegetation, terrestrial and subterranean fauna, as well as information on socioeconomic conditions and cultural heritage sites. Practical value. The considered experience is also useful for Ukraine, since we have a significant part of enterprises in the extractive industry and the issues of environmental protection and nature management should occupy one of the first places in companies. The results of the research can be used by practitioners, scientists, and civil servants for further perspectives of the development.

Published: October 2022

Purpose. Development of a scientific and methodological approach for creating a phase depiction of a cybercrime victim by identifying significant personified characteristics. Methodology. In the process of research, methods of systematization, comparison, grouping, logical generalization, bibliometric analysis, regression analysis (the method of sigma-limited parameterization), and the algorithm of associative rules were used. Findings. According to the results of the research, it was established that the countries with the highest rates of cyber fraud in the field of financial services include Luxembourg (15%), France (14%), Great Britain (13%) and Denmark (11%) are among. In 2020, on average, every 10th resident of the European Union became a cyber victim when performing financial transactions. The results of an empirical analysis using the algorithm of associative rules showed that in 100% of the analyzed cases of cyber fraud in the field of financial services among European residents, stable patterns are found between the following parameters: a married woman who raises three children, a woman aged 5564 years old who raises three children, a married person who periodically experiences financial difficulties and raises three children, a person who lives in a rural area and raises three children, a person aged 6574, who has three children. In addition, the probability for a woman raising three children of becoming a victim of cyber fraud is 87.5%. In 71.4% of cybercrime cases in the field of financial services, a close causal relationship is traced with the following parameters: manual worker who was cyberattacked through a smartphone, a person who periodically experiences financial difficulties and a cyberattack occurred through a smartphone. Originality. The use of profiling technology allows evaluating and predicting the behavior of the financial services consumer in the conditions of the growing risk of cyber fraud based on the systematization and establishment of cause-and-effect relationships between the most informative personalized signs of them. Practical value. The development of a phase depiction of a probable victim of cybercrime in the financial system allows identifying the signs of a cyber threat in the early stages, and immediately reacting to it, thus neutralizing or minimizing the negative consequences. The results of the conducted research will have practical significance for the management of financial institutions and public organizations that specialize in training and raising the level of financial and digital literacy of citizens.

Authors: Mospan Natalia V. , Sysoieva Svitlana O.
Published: October 2022

The COVID-19 pandemic has launched school digital transformation with educational technologies implemented in classrooms worldwide. Teachers and learners have faced the challenges of adaptation to a new mode – digitally-based distance teaching and learning. In this regard, a question arises, whether schools have adapted successfully to new digitally-based distance learning or failed. Therefore, the research is focused on revealing the trends in schools’ digital adaptation and transformation during the COVID-19 pandemic worldwide. The research issue is solved due to a combination of various approaches, e.g. a qualitative content analysis of documents published online in 2020-2021 and conducting surveys and interviews of students at Ukrainian schools from December 2020 to February 2021. These approaches make it possible to reveal positive and negative trends in school digital transformation at macro- and micro levels from the perspective of pandemic-related measures on international and national levels, as well as students’ perception of emergency distance learning. The research presents the ranks of countries in line with the accessibility and affordability of EdTech having been implemented in schools in crisis. Moreover, the research discusses the following issues: the COVID-19 pandemic impact on schools and school-related measures, EdTech implementation in classroom and schools’ digital transition, digital divide and inequity in education, generation gap, learning loss and achievement gap, teacher’s creativity and methodology shift. The collected data supports theoretical insights about trends in school education during the pandemic. The principal findings of the research are that the emergency integration of information technology in school education has changed the traditional way of teaching and learning worldwide. EdTech implementation encourages teachers to provide creative teaching and develop novel approaches to meet Net generation students’ needs in a virtual educational environment. The research results can contribute to policymaking and strategy development of further school digital transformation in times of crisis.
GREPH, Marx and the Politics of Teaching Philosophy
Authors: Mozzachiodi Roberto
Published: October 2022

This article seeks to locate the seminar series that Derrida delivered at the École normale superieure during the mid-seventies within the broader political and theoretical aspirations of the Groupe de recherches sur l’enseignement philosophique (GREPH), particularly considering the group’s thematization and politicisation of pedagogy in the history of philosophy and the philosophical establishment. It also aims to contextualise Derrida’s recourse to a Marxian and Marxist problematic as part of these aspirations in view of his longer-term engagement with the question of philosophy in Marx and Marxism. The article brings together these two contextual dimensions of Derrida’s teaching activities at the ENS through a close reading of the seminar series he delivered on the agrégation topic of Theory and Practice in 1976–7. This reading focuses specifically on how Derrida mobilised the Althusserian problematic to attempt to transform the role and function of the agrégés-répétiteur (a position he shared with Althusser at the ENS) within the frame of reference of his political work with GREPH.
‘Ingratitude! Treachery! Revenge!’: Race, Empire, and Mutinous Femininities in Harriette Gordon Smythies’A Faithful Woman(1865)
Authors: Garrido Felipe Espinoza
Published: October 2022

Harriette Gordon Smythies’ overlooked sensation novel A Faithful Woman (1865) engages with two cultural formations instrumental in shaping the Victorians’ representations of race, and to a large degree, also their understanding of it: The Indian Rebellion of 1857 and minstrelsy. As its various symbolic appropriations of mutinous women show, the novel is highly critical of the easy and essentialising recriminations of ‘vile’ Indianness and offers a keen appreciation of the parallels between the Empire’s racialising oppressions abroad and its gendered oppressions at home. At the same time, however, its representations of African American characters seek to enshrine Britain’s moral superiority vis-à-vis the United States’ slavery system. Particularly, A Faithful Woman’s examinations of racialised imaginations of Indian Britons and African Americans – contrasting, for instance, British sculpture and portraiture with (allegedly) American minstrelsy – speak to its attempt to dissociate the practices of Empire from its former colonies across the Atlantic. Its critical examination of imperial notions of race in post-Rebellion sensation fiction, this article argues, helps to reaffirm the very colonial practices that it seeks to undermine.
Brief Encounters: Sensation Fiction and the Short Story
Authors: Beller Anne-Marie
Published: October 2022

Building on recent work on sensation short fiction, which has convincingly argued for the form’s significance to our knowledge of mid-Victorian sensationalist culture more broadly, this article examines Wilkie Collins’s ‘A Marriage Tragedy’ (1857–58), and Mary Elizabeth Braddon’s ‘Levison’s Victim’ (1870) and ‘The Mystery at Fernwood’ (1861). Through a focus on generic hybridity, marriage, and identity, the connections and divergences between the short and long forms of literary sensationalism are traced, from the passing of the Divorce and Matrimonial Causes Act in 1857 to the first Married Women’s Property Act of 1870. These particular markers reflect the distinct emphasis on matrimony within these texts during a crucial period of public interest in the Marriage Question. It is argued that the sensation short story is more heavily characterised by gothic tropes than its longer counterpart, even as it eschews the supernatural. Female characters in these stories encounter marriage as an uncanny site of terror and are silenced and traumatised by these intimate experiences. Despite the legal reforms and ongoing public debate of the 1860s and 1870s, writers of the sensation short story suggest that modern marriage retains the threats to female liberty, safety, and sanity that characterised the gothic narratives of an earlier period.
Stress-induced pulmonary hypertension: definition and diagnosis
Authors: Naiden T. V. , Bartosh-Zelenaya S. Yu. , Fedoretz V. N.
Published: October 2022

The first hemodynamic definition of pulmonary hypertension (PH) was given at the World Symposium on PH (WSPH, 1973) in Geneva as an increasebin resting mean pulmonary artery pressure (mPAP) >25 mm Hg by heart chamber catheterization. Since 2004, in the definition of PH, in addition to an increase in resting mPAP, an 'exercise' criterion has also been included: mPAP at the peak of exercise >30 mm Hg. However, at the 4th WSPH Symposium in 2008, due to uncertainty of the relationship between age-related changes in cardiac output (CO) and pulmonary vascular physiology, in particular pulmonary vascular resistance (PVR) under exercise, this criterion was excluded.

Resting PH manifests only at the absence of ≥50 % of pulmonary microcirculation, so for the earliest diagnosis of the disease, it’s necessary to use factors that provoke an increase in CO and PVR. Moreover, in clinical practice, manifestations of PH are not uncommon on exercise. In the absence of consensus the definition of stress- induced PH is defined in individuals with normal mPAP (< 25 mm Hg) at rest and elevated mPAP (>30 mm Hg) and PVR> 3 WU at the peak of exercise.

Authors: Druzhinina E. S. , Druzhinin D. S.
Published: October 2022

Introduction. Peripheral nerve ultrasound helps in the differential diagnosis of amyotrophic lateral sclerosis (ALS) and treatable diseases with a similar clinic. The cross–sectional area (CSA) values of the nerves of the hands and spinal nerves in ALS is normal or even reduced in comparison with control. The CSA of the nerves in a clinically similar condition – multifocal motor neuropathy (MMN) increases and has a characteristic ultrasound pattern of changes in the form of an increase in CSA in the proximal parts of the nerves of the hands and spinal nerves of the brachial plexuses.

Materials and methods. Cervical root and peripheral nerve CSA on both sides was performed in 31 patients with ALS and 25 patients with MMN, using a 8–15 MHz linear array probe (ultrasound scanner «Sonoscape S20» (China). The control group included 92 healthy people without diseases of the nervous system, as well as conditions potentially causing damage to the peripheral nervous system.

Results. The average values of the CSA of cervical roots and peripheral nerves in the upper limb in ALS patients were normal. However, there was an increase in the CSA of the median nerve at the shoulder level on the left by 23 %, the radial nerve on the right by 24 %, and the ulnar nerve on the left at the wrist level by 33 % in the ALS group compared with the control group. The CSA of nerves in MMN patients was significantly higher than in ALS and compared with the control group. In MMN nerve trunks increase was observed in the proximal parts of the nerves in the upper limb and cervical roots on both sides.

Conclusions. Peripheral nerve ultrasound is a reliable tool for differential diagnosis ALS and ALS mimics. It can be widely used in routine clinical practice.

Authors: Zaini S N A M , Saad S K M , Abu M Y
Published: October 2022

Patients under the methadone flexi dispensing (MFlex) program are required to do blood tests like liver function profile. A doctor assesses 3 parameters like Alk phosphatase, ALT (SGPT), and AST (SGOT) to ensure the patient has a liver problem. Consequently, the existing system does not have a stable ecosystem towards classification and optimization. The objective is to apply the Mahalanobis-Taguchi system (MTS) in the MFlex program. The data is collected at Bandar Pekan clinic with 34 parameters. Two types of MTS methods are used like RT-Method and T-Method for classification and optimization respectively. The average Mahalanobis distance (MD) of healthy is 1.00 and unhealthy is 352.58. A positive degree of contribution has only 1 parameter. 15 unknown samples have been diagnosed. Type 2 of 6 modifications has been selected as the best-proposed solution. In conclusion, a pharmacist from Bandar Pekan clinic confirmed that MTS can solve problems in the classification and optimization of MFlex program.
Review of Particle Detachment and Attachment in Porous Media
Authors: Ogolo Naomi Amoni , Onyekonwu Mike
Published: October 2022

Particle detachment, migration and attachment are common processes in porous media, especially in unconsolidated formations. In this review, the processes are discussed and equations describing the processes are presented. Two particle detachment processes analyzed are the hydrodynamic forces and electric double-layer forces. The particle detachments equations were critically examined to determine if they reflect crucial factors that trigger particle detachment in porous media. Essential factors that are missing in the equation are the effect of pressure and the level of rock consolidation. Incorporating the level of rock cementation and the effect of pressure in the equations will make the models more empirical and less theoretical. For particle attachment, Van der Waals forces, adhesion, particle attachment efficiency, and straining processes and their equations are considered. The colloidal forces are all embraced in terms of capturing important elements that mobilize particles in porous media, however, the practical application of the models can pose a challenge. For particle adsorption on grain surfaces, it is recommended that the effect of pressure and temperature be studied.

Published: October 2022

The aim of this article was to compare the predictive abilities of the optimization techniques of response surface methodology (RSM), the hybrid of RSM–genetic algorithm (RSM–GA) and adaptive neuro-fuzzy interference logic system (ANFILS) for design responses of % removal of naphthalene and adsorption capacity of the synthesized composite nanoparticles of chitosan–cetyltrimethylammonium bromide (CTAB)–sodium bentonite clay.  The process variables considered were surfactant concentration, , activation time, ,  activation temperature, , and chitosan dosage, .  The ANFILS models showed better modeling abilities of the adsorption data on the synthesized composite adsorbent than those of ANN for reason of lower % mean absolute deviation, lower % error value, higher coefficient of determination, , amongst others and lower error functions’ values than those obtained using ANN for both responses.  When applied RSM, the hybrid of RSM–genetic algorithm (RSM–GA) and ANFILS 3–D surface pot optimization technique to determine the optimal conditions for both responses, ANFILS was adjudged the best.  The ANFILS predicted optimal conditions were = 116.00 mg/L, = 2.06 h, = 81.2oC and = 5.20 g.  Excellent agreements were achieved between the predicted responses of 99.055% removal of naphthalene and 248.6375 mg/g adsorption capacity and their corresponding experimental values of 99.020% and 248.86 mg/g with % errors of -0.0353 and 0.0894 respectively.  Hence, in this study, ANFILS has been successfully used to model and optimize the conditions for the treatment of industrial wastewater containing polycyclic aromatic compounds, especially naphthalene and is hereby recommended for such and similar studies.
