Epidemia niepamięci. „Pomór” Wałerija Szewczuka
Authors: Zambrzycka Marta
Published: December 2022

The article concerns the novel The Plague (1989) by Valeriy Shevchuk, in which the author explores the motif of epidemic. In the novel, the epidemic is a metaphor for the lack of historical and cultural memory caused by an oppressive political system. Presented as a form of cultural and national amnesia, it serves as background for reflection on the post-totalitarian heritage of contemporary Ukrainian society. Valeriy Shevchuk’s novel is based on historical documents, but it is not a work of literary realism, but rather a kind of morality play that deals with universal issues.
Live to Tell, or, The 2020 “Framework for Hatred”
Authors: Vidović Schreiber Tea-Tereza , Miletić Josip
Published: December 2022

The paper discusses intertextuality in Ivan Aralica’s novel Okvir za mržnju (A Framework for Hatred). The interference of the oral and the written medium is analysed not only at the level of primary orality (various oral and marginally oral forms) but also at the level of secondary orality, often referred to as “new orality,” which is transmitted through new, different media (for example, newspaper text, radio, television, and wall newspapers). The comparative method will be used to present the motif of a scabies contagion in the novel, with the presence of oral literature as a medium for discussing everything that the contagion entails. Parallels will be made with modern oral forms (memes), which are most often transmitted via Viber, WhatsApp, Internet, Facebook and Instagram today, and which currently feature the COVID-19 pandemic in Croatia and the world. Given that history is the teacher of life, it is perfectly understandable that this novel by Aralica, based on historical facts and experiences surrounding contagion, can serve as an example of how to tackle similar challenges of the present. It is this long-established hypothesis that shows the aim of the paper, not only at the level of the theme and motifs, but also on an experiential level, which includes a number of different emotional states (from hatred to laughter) caused by the political and social circumstances of a community which often observes its history and present through the prism of conspiracy theories. Although the novel A Framework for Hatred is valued differently by many critics, this paper reintroduces the possibility of reconsidering the canonical value of this work, bearing in mind that literary texts sometimes outgrow their own authors, especially at times when the contemporary reader’s self is reflected in the text and subtext of a newer, recognisable social context.
Время двух пандемий в „Повести о смерти” Марка Алданова
Authors: Szewczenko Ludmiła
Published: December 2022

One of the key subjects of M. Aldanov’s A Novel about Death is the cholera pandemic of 1847–50. The author of this article views Aldanov’s work in the context of history, medical science, poetics, philosophy and aesthetics and applies the historical-literary and cultural-historical methods of research. Doing so demonstrates how the phenomenon of the pandemic is construed by M. Aldanov in the paradigm of the philosophy of a happenstance. The article traces how the motif of sickness in A Novel about Death is intertwined with Aldanov’s attempts to comprehend the strive for revolutions that engulfed Europe, and analyzes in detail how the use of a morbid code is metaphorically extrapolated on the entirety of issues raised in the novel.
Jak Rosja walczy z „tęczową zarazą”, czyli dyskurs anty-queer we współczesnej rosyjskiej przestrzeni kulturowej
Authors: Świetlik Anna
Published: December 2022

This article is an attempt to outline the anti-queer discourse in the contemporary Russian cultural space. The analysis focuses mainly on the film Firebird (Жар-птица), which is a very rare example of queer cinema aimed at a wide Russian audience. In order to indicate the features of the homophobic policy of the authorities towards cultural representations of queer issues, the author references research conducted in the field of social sciences and certain press materials devoted to the premiere of the film. The analysis proves that, despite the intensely promoted (both in political and cultural spheres) anti-homosexual policy, the mass consciousness of the Russian audience was more liberal than it was perceived (at least to a certain extent), and the actions taken by the authorities and politicians did not bring expected results.
Pathways to Transition: Jan Cygan and the Neo-Philological Tradition
Authors: Kuźniak Marek , Litwin Maciej
Published: December 2022

Jan Cygan’s (1927–2021) linguistic thinking laid out in 1976 relied on self-contained form-based structuralism, but it also incorporated elements of emerging context-based structuralism. As such, it was animated by concepts that effectively implied divergent views on the foundational postulate of linguistic arbitrariness underlying structural linguistics. Cygan approached the inner tensions of changing linguistic paradigms in a manner that may be studied as a case in linguistic ethics. This ethic manifests itself in an attitude toward the linguistic fact, as discussed through the lenses of a linguistic model. Today, it is possible to comment on the period of transition in question, falling back on the achievements of cognitive linguistics. Cygan’s stance may be interpreted in terms of the IN-OUT conceptual schema. This interpretation not only highlights the merits of the position emerging from Cygan’s 1976 general linguistics introduction, but it also views this position as a solution to a more fundamental problem facing linguistic ethics today and in the future.
Польские школы в Барнауле (40-е гг. ХХ в.): некоторые аспекты изучения
Authors: Nikulina Irina
Published: December 2022

The article is devoted to the little known question of the establishment of Polish schools in Barnaul operating in the 1940s. Some studies tackling the subject matter to some extent can already be found in Polish and Russian historiography. On the basis of the available material and literature the author of the article seeks to sum up the information about the Polish schools in Barnaul, capital of the Altai Krai, and to present the role and activity of Lidia Milewicz, a teacher, in the establishment and then provision of education. The author uses documents relating to school no. 2 for Polish children in Barnaul (record books, registers), currently kept in Warsaw’s Museum of Independence and made available to the author by Anna Milewska-Młynik, an employee of the museum. The documents were also an inspiration for the article. The author discusses some aspects of the establishment and functioning of educational facilities for Polish children. The schools made their contribution to and introduced national specificity into the school education system in the Altai Krai. The problem examined in the article should certainly be explored further through the use of new source material and expansion of the document base.
POLA HIJRAH ZAMAN NOW PERSPEKTIF ‘UZLAH
Authors: Zamroni Muhammad
Published: January 2023

The word hijrah is currently experiencing an expansion of meaning. Initially, hijrah meant moving from one place to another in search of protection. Now hijrah is interpreted as a condition in which a person intends and is committed to being better. Hijrah is the realization of repentance that is done first and has implications for positive attitudes in society. The implementation of this hijrah is carried out first to continue implementing 'uzlah. As for 'uzlah is an action taken by someone who tries to isolate himself from the crowd to get closer to Allah swt. namely, focusing on taqarrub to Allah swt. Seeing the concept of hijrah, there is a similarity in meaning to the concept of 'uzlah in Sufism. Therefore, here the author tries to compare the two. If we compare today's hijrah with 'uzlah' then we will find a common ground that today's hijrah is a person's starting point to do 'uzlah to Allah swt. If someone can carry out the hijrah correctly, implement the values ??of the hijrah that he is living, then over time that person will definitely try to make 'uzlah' to Allah swt. Because when there is a person's intention and commitment to emigrate, it will not be perfect if his worldly affairs are still above his ukhrawi affairs. When someone has emigrated with the true meaning of hijrah, then that will lead him to the act of 'uzlah to Allah swt. The perfection of 'uzlah will be felt when someone who has migrated has implemented the concepts of takhalli, tahalli, and tajalli well.

Authors: Yapanto Alvian Mohamad , Isnaeni Aulia Rahma , Lestari Khairani Ayu , Satyarsa Agung Bagus Sista
Published: December 2022

COVID-19 transmission necessitates health workers to use personal protective equipment (PPE), especially protective masks when delivering medical services. Long-term use of protective masks might cause facial skin injuries. Our study aims to provide a systematic review to explore the phenomenon and incidence of protective masks induced facial skin injuries in primary healthcare workers. This systematic review was created by obtaining articles from the PubMed database and the Cochrane library from 2020 to 2021, using the keywords "Face skin injury," "Wearing protective masks for a long time," and "Wearing protective masks and facial skin disorders." Inclusion criteria were studies that fully report the phenomenon of wearing protective masks and the incidence of facial skin injuries. One hundred and sixty-eight studies were obtained, but only 14 articles matched the inclusion criteria with more than 10,430 participants from different countries that covered various characteristics of facial skin injuries in primary healthcare workers. The findings obtained dominant characteristics of health workers who experienced facial skin injuries: women, N95 masks, and daily N95 coverage for more than 6 hours (p<0.05). Facial skin injuries are often seen after using protective face masks, as it is used for an extended period as part of a defensive effort during work. Therefore, measures that protect health workers from COVID-19 and prevent health workers from potential injuries of protective masks must be taken into account.

Published: December 2022

COVID-19 has a wide disease spectrum. Different presentations may be seen in different people, with uncertain long-term fate. The amount and longevity of immunity provided among the infected also vary from person to person which might in turn affect the chances of re-infection. Current study tries to uncover the incidence, disease severity and outcomes amongst those who have been previously hospitalized for COVID-19. A prospective cohort study where all patients admitted to intensive care facility at the tertiary care center were followed up for any occurrences of re-infection for more than one year. All cases were followed up telephonically and at scheduled visits to the hospital by trained personnel. A total of 410 cases with a mean age of 59.8 years, including 310 (75.6%) males and 100 (24.4%) females. Among these 410 patients 287 remained alive till the end of study period. Re-infection rates among recovered ICU admitted seriously ill patients were 1.4% whereas the rate of ICU re-admission due to COVID-19 re-infection was only 0.7%. Re-infection among female was 1.1% whereas in male was 1.5%. ICU readmission rate among female was 1.1% while in male was 0.5% only. The chances of re-infection in female were seen less than that in males, but the severity of re-infection in females was found to be higher. COVID-19 re-infection in previously severely infected COVID-19 patient is not so common. The chances of a severe disease among such cases are even rarer.

Published: December 2022

The high demand for N95 masks, especially during the COVID (Coronavirus disease)-19 pandemic, has caused shortages worldwide. This study aimed to examine the sterilization ability of the portable sterilizer prototype for N95 masks and its effect on the filtration ability and changes in air resistance on the N95 mask in order to thrift personal protective equipment (PPE) use during a shortage. The sample used was an N95 mask type 1860. The mask was contaminated with 0.6-0.8 MFU Staphylococcus aureus and Escherichia coli. The sterilization methods used were Ultraviolet Germicidal Irradiation (UVGI), Heat at 75°C, and a combination of both from 1 to 120 minutes. Next, the masks were cultured in a nutrient agar medium. For aerosol penetration and air resistance tests, masks were tested before and after the sterilization process, lasting from 5 to 60 minutes. This prototype sterilizer with Heat effectively killed E. coli and S. aureus starting from 3 minutes. The filtration ability of the N95 mask was maintained at >95% even after the sterilization process with 75°C heat, UVC, or a combination of both for up to 60 minutes. There was also no significant difference in air resistance between new masks and masks that had been sterilized using a portable sterilizer. This prototype sterilizer with Heat at 75°C can effectively sterilize against both gram-positive and negative bacteria in the N95 mask without reducing the aerosol filtration ability and changing the air resistance of the N95 mask.

Published: December 2022

The existence of the Covid-19 pandemic requires all people to stop and shift all activities outside the home to be all online, including in the education sector. The distance learning system requires learners to adapt to this new learning pattern. The existence of a digital library helps all the information needs of users during the Covid-19 pandemic through its various services that provide easy access to information needed by the public effectively. The preparation of research is intended to determine the role of digital libraries in supporting learning and providing credible information to the public by analyzing research themes/topics, research methods, and research results. This study applies a narrative literature review type literature study method to five reference sources indexed in Google Scholar with a span of the last ten years. The results showed that digital libraries with various types of services they offer can maintain the quality of information circulating among the public and facilitate access to information so that the teaching and learning process, research and development of science becomes smoother and easier even during the Emergency of the Covid-19 pandemic. Research on digital libraries uses many types of research methods such as qualitative research methods, literature study methods, and Systematic Literature Review (SLR) methods. From the five references analyzed, it can be concluded that digital libraries can be used as a tool to find and obtain learning resources and relevant information during the Covid-19 pandemic. Digital library management requires reliable librarians as parties who distribute all information and knowledge into digital form.
Discutindo o relacionamento: bolero e samba-canção nas tramas estéticas, políticas e comunicacionais do pós-guerra
Authors: Santos André
Published: December 2022

As sentimentalidades do samba-canção e do bolero que tomaram o rádio, os discos e os espaços de diversão noturna de meados da década de 1940 até o final da seguinte foram, por muito tempo, negligenciadas pela crítica e pela historiografia da música popular brasileira. Refletem-se nelas, porém, as grandes tensões estéticas, políticas e sociais de seu tempo, não só no Brasil, mas em toda a América Latina. Este trabalho busca mapear tais tensões no diálogo entre os dois gêneros, tendo como apoio o conceito de hibridização cultural, que implica a busca pelos sentidos de ambiguidade e ambivalência na produção musical em questão.
Algorithm of the autonomous initial alignment of sins with sequential filtering
Authors: Meleshko Vladyslav
Published: December 2022

An algorithm for an autonomous initial alignment of a strapdown inertial navigation system on a fixed or limitedly movable base is proposed and considered. It sequentially uses two Kalman averaging filters in. The first one determines one column of the directing cosines matrix (DCM) between the axes of the associated with the object and the geographical accompanying bases by the signals of the accelerometers. The second filter determines the second column of the matrix based on the gyroscope signals and the obtained estimates of the direction cosines. The third column is determined from known ratios. From the resulting DCM, the heading, pitch and roll angles are determined. Information signals for solving the problem are obtained by averaging a small interval (5 s) at the end of the Kalman filter transition process. This allows minimizing errors from changing the position of the object during the measurement time, which can reach tens of minutes. The advantage of the algorithm is the independence of errors from the object heading. It is shown that pre-smoothing of signals improves accuracy. The algorithm makes it possible to determine the orientation angles, and then the direction cosines at a measurement time insufficient to complete the transient evaluation process by the Kalman filter. The conducted field experiments confirm the good characteristics of the alignment on a fixed and vibrating base, achieved using the algorithm.
Frequency characteristic of a uniformly rotating laser gyro in exact and polynomial forms
Authors: Bondarenko Evgen
Published: December 2022

In some inertial navigation systems of a carousel type, laser gyros operate in regime of uniform rotation. For development of such systems and computer simulation of their work, one needs to have the “exact” (in wide range of angular velocities ) analytical expression for counterpropagating waves beat frequency  of  uniformly rotating device. This expression may be obtained by solving the well-known system of laser gyro dynamic equations with accuracy to second order in parameters of counterpropagating waves linear coupling. But before use of such non-dithered laser gyros in the named inertial system, their metrological parameters (scale factors and null shifts) must be preliminary calibrated. For synthesis and qualitative analysis of methodical errors of the procedure of such calibration on a quickly rotating platform of a single-axis stand, one needs also to have the approximate analytical expression for counterpropagating waves beat frequency in the form of polynomial

with coefficients , ...,   which involve parameters of the exact expression for . As analysis of the literature shows, the known expression for  and the known relations for some of coefficients of polynomial  are not complete and, therefore, must be modified. In the paper, the result of such modification is presented.
About an alternative method of autonomous determination of latitude and longitude of moving objects
Authors: Avrutov Vadym , Ryzhkov Lev
Published: December 2022

In this article, an analytical review of the literature on methods for measuring the stabilization error of stabilization systems (SS) is carried out. The relevance of further research and development in the field of ways to improve the accuracy of measurements of the stabilization error of the SS is substantiated.

The modern method for determining the median error of the SS has distinctive features and has a number of advantages: it requires much less time and the use of manual labor; performed in digital form of information processing in numerical and graphical form; does not require the need to install a movie camera (it was replaced by an optoelectronic module, information from which is fed to the input of a video monitor, to which it is connected via the Pinnacle Movie Box Plus USB matching device, through which the video image is transmitted for recording to a laptop). After performing the research, information according to a specially developed program is automatically processed on a computer, which, based on the results of calculations, gives a more accurate (compared to the new method) value of the median stabilization error along the horizontal and vertical guidance channels.

The model of construction of the line of domestic SS corresponds to the principle of "dependent stabilization" rigid connection of vertical and horizontal channels of the stabilizer with the device of supervision over objects.
On autonomous determination of object location latitude by one component analytical gyroscopic compass
Authors: Zamorskyi Oleksii
Published: December 2022

A method of autonomous determination of object location latitude by one-component analytical gyroscopic compass in static mode using a single gyroscopic angular velocity sensor is reviewed. A scheme of scanning one-component analytical gyroscopic compass is selected that additionally provides the vertical direction of the input axis of the angular velocity sensor during the scanning process. Algorithms are developed to make the calculation invariant to zero offset and scale factor of the angular velocity sensor under the conditions of triple measurements of its output characteristics and also invariant to azimuth angle of the initial position of the input axis of the angular velocity sensor during the scanning under the condition of quadruple measurements. A general estimation of errors of autonomous determination of latitude by the one-component analytical gyroscopic compass is provided.
Influence of flight mode on loads from turbulent air
Authors: Hevko Bohdan , Bondar Jurii
Published: December 2022

This paper investigated the influence of altitude and flight speed on the loads arising on the elastic wing of a turbojet aircraft of conventional layout, which falls into turbulent conditions. The aircraft structure is modeled by elastic beams with appropriate weight and stiffness distribution. Performed a modal analysis of the aircraft design and examined the influence of the number of calculated tones own oscillations on the loading of an aircraft wing. Aerodynamic forces and moments are determined by the dipole lattice and constant pressure method (DLM/CPM). Non-stationary characteristics are also taken into account, as required by certification specification. Determining the effect of flight speed showed the need to consider both the minimum and maximum speeds, because at minimum speed the end zone of the wing is loaded more, and at the cruise speed ‒ the root section. When analyzing the effect of flight altitude on the load, determined that the maximum values of transverse force and bending moment occur when flying at minimum altitude, and the torque on the wing reaches the maximum value at altitudes with the maximum Mach number. Separately highlighted loads of aircraft wing at horizontal balanced flight. Also showed that the speed of flight, namely the Mach number, significantly affects the torque that occurs on the wing.

Authors: Zadorozhna Iryna , Datskiv Olha
Published: December 2022

The problem of motivation in foreign language learning has always been of great importance. Researchers agree on the non-static, dynamic nature of motivation, investigate the role of the motivational context, and recognize the fact that some aspects of motivation are not internal but are externally determined by the learner’s sociocultural environment. The study aims to investigate the prevalent type of motivation among pre-service English teachers in challenging circumstances. The analysis of motivation sources and ways to protect and maintain motivation to learn English as a foreign language in challenging circumstances constitutes the novelty of the study. 60 fourth-year students (57 females and 3 males) participated in the investigation. The questionnaire adapted from Gardner's Attitude/Motivation Test Battery (AMTB) has  been used as a tool to collect quantitative data. The results reveal that the level of motivation is high with a prevalence of instrumental motivation. Qualitative data have been obtained from interviewing students. During the interviews, the students identified the sources of their motivation, critically evaluated their learning situation, and described their learning circumstances as challenging. The study suggests pedagogical implications in line with positive psychology recommendations and the latest research on the protection and maintenance of а motivation to learn English as a foreign language in challenging circumstances. The implications for teachers include developing motivational strategies, maintaining engagement, providing role models, using technology.

Authors: Kaliuzhnyi Volodymyr , Sytnyk Stanislav , Titarenko Аndrii
Published: December 2022

Using the finite element method, mathematical models were created and studies were carried out of direct and reverse methods of hot crimping in a matrix of a special profile of hollow workpieces made of high-carbon steel with a variable wall thickness along the height. A plastic model of metal and cylindrical coordinates are used. By calculation, the shape and dimensions of the initial workpiece for crimping were established, which provided the required dimensions of the product. Before crimping, a part of the billet was heated along the height, which was subject to deformation in the matrix. The use of a matrix of a special profile with a deforming surface made with annular protrusions made it possible to obtain a product in one step due to a decrease in the influence of friction forces during shaping. The deformation rate is determined to comply with the hot deformation mode during the crimping. The dependences of the axial force on the deforming tool on the movement of punches and the distribution of specific forces on the contact surfaces are established. The use of direct crimping leads to a decrease in forces modes and specific forces on the tool. The final stress-strain state of the metal, the shape and dimensions of the product are determined. According to the distribution of strain intensity, an assessment was made of the elaboration of the metal structure by plastic deformation. Based on the simulation data, a design of the general view of the die tooling for direct crimping has been developed.

Authors: Kovalev Vasyl , Chenyu Wei
Published: December 2022

Modern moving objects containing large volumes of liquid need to ensure stability on the movement trajectory, reliability of control during maneuvers, as well as the ability to predict and prevent extreme movement conditions. The presented article provides review materials devoted to the research results into inertial flows of viscous incompressible fluid in tanks with internal damping baffles. In order to exert force on resonant excitations from the liquid side and to compensate for the instabilities of moving objects, the analysis and design of rational structures of influence means on currents is carried out.
Among the most effective means of damping should be noted rigid internal baffles of various designs installed in tanks in the most likely areas where instabilities and sources of excitation of resonant fluid movements may occur. Flat rigid partitions, profiled permeable damping surfaces, perforated and retaining elements, enslavers of liquid due to surface tension forces, etc., require comprehensive and detailed study and analysis.

Authors: Kaliuzhnyi Volodymyr , Aliieva Leyla , Yarmolenko Oleksandr , Sytnyk Stanislav
Published: December 2022

The work is devoted to researching a new method of hot direct-reverse extrusion of hollow conical products from high-carbon steel and determinated parameters for technological design. The considered method makes it possible to obtain in one step hollow products with different wall thickness in height, while the wall thickness in the upper part of the product can be greater than the thickness in the bottom part. The dimensions of the initial workpiece are determined by modeling using the finite element method, which ensures the simultaneous flow of metal in the forward and reverse directions during the process of forming the product, which reduces the deformation force. The use of this method also leads to a decrease in the heating of the deforming tool due to a decrease in the contact area of the deformed workpiece with the tool. The strain rate is determined to ensure the temperature interval of extrusion. The dependencies of the force of extrusion, removal of the punch from the deformed workpiece, pushing the product out of the matrix on the movement of the corresponding tool are established. The final shape and dimensions of the product with the distribution of temperature and deformations were found. For the maximum amount of extrusion force, the distributions of specific forces on the contacting surfaces of the punch, matrix, ejector and stress on the volume of the deformed workpiece were found. According to the obtained data, the technology of direct-reverse extrusion can be developed and implemented on universal press equipment, which has high productivity due to the reduction of the number of stamping steps. The design of the stamp for extruding products of certain sizes with forced cooling of the matrix is given.

Motion Control of a Spherical Robot with a Pendulum Actuator for Pursuing a Target
Authors:   Chuvash State University, Mikishanina E. A.
Published: December 2022

The problem of controlling the rolling of a spherical robot with a pendulum actuator pursuing a moving target by the pursuit method, but with a minimal control, is considered. The mathematical model assumes the presence of a number of holonomic and nonholonomic constraints, as well as the presence of two servo-constraints containing a control function. The control function is defined in accordance with the features of the simulated scenario. Servo-constraints set the motion program. To implement the motion program, the pendulum actuator generates a control torque which is obtained from the joint solution of the equations of motion and derivatives of servo-constraints. The first and second components of the control torque vector are determined in a unique way, and the third component is determined from the condition of minimizing the square of the control torque. The system of equations of motion after reduction for a given control function is reduced to a nonautonomous system of six equations. A rigorous proof of the boundedness of the distance function between a spherical robot and a target moving at a bounded velocity is given. The cases where objects move in a straight line and along a curved trajectory are considered. Based on numerical integration, solutions are obtained, graphs of the desired mechanical parameters are plotted, and the trajectory of the target and the trajectory of the spherical robot are constructed.
The role of TDP-43 protein in amyotrophic lateral sclerosis
Authors: Włodarczyk Piotr , Witczak Mikołaj , Gajewska Agnieszka , Chady Tomasz , Piotrowski Igor
Published: December 2022

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease where both upper and lower motoneurons are damaged. Even though the pathogenesis of ALS is unclear, the TDP-43 aggregations and non-nuclear localization may be crucial to understanding this process. Despite intensive research on ALS therapies, only two lifespan-prolonging medications have been approved: Riluzole and Edaravone. Unravelling the TDP-43 pathology could help develop new ALS therapies using mechanisms such as inhibition of nuclear export, autophagy, chaperones, or antisense oligonucleotides. Selective inhibitors of nuclear export (SINEs) are drugs that block Exportin 1 (XPO1) and cause the accumulation of not exported molecules inside the nucleus. SINEs that target XPO1 are shown to slightly extend the survival of neurons and soften motor symptoms. Dysfunctional proteins, including TDP-43, can be eliminated through autophagocytosis, which is regulated by the mTOR kinase. Stimulating the elimination of protein deposits may be an effective ALS therapy. Antisense oligonucleotides (ASO) are single-stranded, synthetic oligonucleotides that can bind and modulate specific RNA: via ribonuclease H, inducing their degradation or inducing alternative splicing via blocking primary RNA transcripts.  Current ASOs therapies used in ALS focus on SOD1, C9ORF72, FUS, and ATXN2, and they may be used to slow the ALS progression. Reversing the aggregation is a promising therapeutic strategy. Chaperones control other proteins' quality and protect them against stress factors. Due to the irreversible character of ALS, it is essential to understand its complicated pathology better and to seek new therapies.
PERSINGGUNGAN KONSTITUSI, IDEOLOGI DAN AGAMA DALAM KEHIDUPAN BERBANGSA DAN BERNEGARA DI INSONESIA PADA ERA REFORMASI
Authors: Sukirno
Published: December 2022

Persinggungan konstitusi, ideologi dan agama seringkali diperdebatkan dan dibenturkan. Ketiganya merupakan landasan berbangsa dan bernegara, namun ideologi dan agama acapkali dianggap sebagai dua kutub yang saling bertentangan. Tulisan ini merupakan kajian yuridis normatif dengan analisis kualitatif berdasarkan pendekatan historis-sosiologis terhadap masalah posisi UUD 1945,Pancasila, dan Agama (Islam), serta pola persinggungan ketiganya dalam kehidupan berbangsa dan bernegara di Indonesia pada Era Reformasi. Fakta historis membuktikan, persinggungan UUD 1945, Pancasila dan Agama selalu menjadi sebuah dialektika, meskipun perdebatan akademis sudah dianggap selesai dan final. Pada era reformasi, pembenturan UUD 1945, Pancasila dan agama mencuat kembali yang oleh Pemerintah kemudian ditindak tegas dengan alasan penegakan UUD 1945 dan Pancasila, serta menjaga keutuhan NKRI.
Unravelling Anti-Feminism: On the Domestication of Resistance
Authors: Thomas Kylie
Published: December 2022

This article provides a critique of neoliberal feminism and argues for nuanced and critical approaches to the question of what constitutes feminist resistance. It focuses on visual artist Billie Zangewa’s creative practice and positions it within the longer history of how women have made use of traditional crafts, such as quilting and embroidery, as a means of expression and as a form of resistance. It positions Zangewa’s work alongside that of some of her feminist contemporaries who have also used thread and cloth in their work to reveal how the political is woven through the fabric of everyday life. I argue that in order to understand why Zangewa’s seemingly mundane, even bourgeois practice, has been framed and taken up as a form of feminist resistance, it is necessary to read her work through a historical lens that takes colonial dispossession and the brutal history of violence in Southern Africa into account. My readings of Zangewa’s work acknowledge the significance of the artist’s affirmation of care and self-love as resistance, as much as they point to the limits of a politics that valorises (unpaid) domestic work and fails to address the structural violence of capitalism.

Entangled Dual Universe

Published: December 2022

Advances in cosmology and astronomical observations over the last two decades have revealed significant tensions and many ambiguities within the standard model of cosmology of a spatially flat Universe, the lambda cold dark matter model. Moreover, the recent Planck Legacy 2018 (PL18) release has confirmed the presence of an enhanced lensing amplitude in the cosmic microwave background (CMB) power spectra, which prefers a positively curved early Universe with a confidence level higher than 99%. This paper addresses the study of a quantum mechanism that could replace the concept of dark matter and energy by considering a primordial curvature as preferred by the PL18 release while yielding the present-day spatial flatness. The implied primordial curvature is incorporated as the background curvature to extend the field equations in terms of the brane-world modified gravity. The Universe evolution is modelled by utilizing a new wavefunction of the Universe that propagates in the bulk with reference to the scale factor of the early Universe and its radius of curvature upon the emission of the CMB, which revealed both positive and negative solutions. This characteristic implies that a pair of entangled wavefunctions was created and evolved in opposite directions as a manifestation of distinct matter and antimatter sides of the Universe. The wavefunction indicates a nascent hyperbolic expansion away from early energy is followed by a first phase of decelerating expansion during the first 10 Gyr, and then, a second phase of accelerating expansion in reverse directions, whereby both sides free-fall towards each other under gravitational acceleration. The predicted background curvature evolution demonstrates the fast orbital speed of outer stars owing to external fields exerted on galaxies as they travelled through earlier conformally curved spacetime. Finally, the wavefunction predicts an eventual phase of rapid spatial contraction that culminates in a Big Crunch, signaling a cyclic Universe. These findings reveal that early plasma could be separated and evolved into distinct sides of the Universe that collectively and geometrically inducing its evolution, physically explaining the effects attributed to dark matter and energy.
Solving the Mystery of Time and Unifying Relativity with Quantum Mechanics
Authors: Niemz Markolf H. , Stein Siegfried W.

Today's concept of time traces back to Albert Einstein's theories of special (SR) and general relativity (GR). In SR, uniformly moving clocks are slow with respect to my clocks. In GR, clocks in a more curved spacetime are slow with respect to my clocks. Many physicists anticipate that GR has an issue as it isn't compatible with quantum mechanics. Here we show: "Einstein time" (Einstein's concept of time) has an issue because it takes the proper time of an observer as the fourth coordinate of all objects in the universe. We replace Einstein time with "Euclidean time", which takes the proper time of an object as its fourth coordinate. SR and GR work very well as long as we describe the world on or close to Earth. Only then does time flow in one direction for all objects. In all other cases, we must take a 4D vector "flow of time" into account. Unlike other models of Euclidean relativity (ER), we claim that reality is formed by projecting 4D Euclidean spacetime (ES) to an observer's 3D space. We prove: The Lorentz transformation is recovered in ER; gravitation relates to a rotation in ES; ER is compatible with quantum mechanics. We solve 13 mysteries, such as time's arrow, mc2, Hubble's law, the Hubble constant, the wave–particle duality, and quantum entanglement. Four concepts of physics (cosmic inflation, expansion of space, dark energy, non-locality) turn out to be redundant. We conclude: As ER outperforms SR and GR, Occam's razor knocks out Einstein time.

This lack of information is due to the primary role of HSTs in fungal pathogenesis, which often masks the functions of NSTs and CWDEs. So, the toxic effects of A. alternata metabolites due to NSTs and CWDEs have received minor attention than those reported for HSTs mycotoxins [11]. A wider study of the activity of isolated fungal metabolites can allow the identification of compounds directly related to the pathogenic activity of the fungus, making it possible to create chemo libraries that facilitate the linking of the structure of the compounds with the species that produce it and its effect on host and non-host crops, as well as with biosynthetic features [12]. In this context, our work reports a study focused on NSTs and CWDEs used by an A. alternata strain isolated from infected pears in Italy. To this aim, the characterization of hydrolytic enzyme activities of A. alternata and the identification of the metabolites produced in vitro were performed. Furthermore, the phytotoxic activity of the isolated compounds was evaluated on pear (host and non-host varieties) and lemon fruits [13]. Finally, the competition of A. alternata with other pathogens was evaluated to investigate the role of NSTs on co-infections.
Relapsing Review: A Research Update on Borrelia miyamotoi
Authors: Cleveland Dawn , Anderson Cassidy , Brissette Catherine A.
Published: December 2022

Borrelia miyamotoi is an emerging tick-borne pathogen in the Northern hemisphere and is the causative agent of Borrelia miyamotoi disease (BMD). B. miyamotoi is vectored by the same hard-bodied ticks as Lyme disease Borrelia, yet phylogenetically groups with relapsing fever Borrelia, and thus has been uniquely labeled a hard tick-borne relapsing fever Borrelia. Burgeoning research has uncovered new aspects of B. miyamotoi in human patients, nature, and the lab. Of particular interest are novel findings on disease pathology, prevalence, diagnostic methods, ecological maintenance, transmission, and genetic characteristics. Herein we review recent literature on B. miyamotoi, discuss how findings adapt to current Borrelia doctrines, and briefly consider what remains unknown about B. miyamotoi.
