Unfolding Exergame Roles to Improve Pre-Service Education Teachers’ Physical Activity Levels Using Drawings Analytics
Authors: Zulkifli Ahmad Fahim , Danis Ajau
Published: February 2024

The exergame concept allowed us to promote physical activity (PA) through games. It helps to normalise PA rather than segregate or exclusive PA to certain times or settings. Nonetheless, studies on exergames during online distance learning are currently scarce. Therefore, this study aimed to explore participants’ insights and feelings towards exergame concepts to promote physical activity (PA). Specifically, aspects such as participants’ understanding, knowledge, and motivation with the exergame were analysed through drawings to investigate how the exergame influences their engagement with PA and learning during online distance learning (ODL). This study adopted a qualitative research design. Drawings were utilised to explore participants’ perceptions, motivation to play, and exergame as a teaching tool. The participants comprised 45 first-year undergraduate physical and health education (PHE), biology, and chemistry major students aged between 20-25 years. The Interpretive Phenomenological Analysis approach was adopted to develop the procedures while Consider.ly software [Usertime Solutions GmbH] was used to analyse data from the videos and drawings. Findings indicate that (i) emoticons were used to represent the changes in feelings among the participants throughout the intervention; (ii) the use of objects, symbols, and characters to portray the sense of protection, togetherness, and curiosities; and (iii) the combination of split drawings were used to express differences between ideas and thoughts on exergame approach among participants. Overall, the findings demonstrated the exergame potential (e.g., higher learning ownership, student-centred) and challenges (e.g., accessibilities, game-built quality) which helped inform future teaching planning and practices to promote meaningful learning experiences during distance learning.
“Healed” Appendix is not actually “Healed” from the surgeon’s perspective: Is it a histopathologic misnomer?
Authors: Srivastava Pankaj , Srivastava Shalini
Published: February 2024

The study aims to present a refute for the use of histopathologic diagnostic nomenclature of the word “Healed” in the perspective of the appendix after appendectomy. Appendectomy is being done worldwide for the acute inflammation of the appendix in golden hours or as an interval appendectomy after the subsidence of the features of inflammation for recurrent appendicitis. The word “Healed” presents a negative psychological impact on the patients as they think that their already “Healed” appendix is unnecessarily removed by the surgeon whereas the pathologist friends use this nomenclature only by the presence of features of any healing wound like fibrosis, eosinophils etc. We also present gross examination findings, histopathologic microscopic features along with photomicrographs of the few appendectomy specimens which were laparoscopically operated for the recurrent appendicitis.

The determination of fibroblast and keratinocyte death types after their transplantation into γ-irradiated porous scaffold in vitro
Authors: Kot Y. H. , Kot K. V. , Kurbanov R. A.
Published: February 2024

In the course of radiation therapy, normal cells surrounding the tumor are also irradiated. During and after irradiation, they undergo a series of structural and metabolic changes, which can lead to cell death or transformation. Therefore, when planning and conducting radiation therapy, the effects of radiation on normal cells are taken into account with the aim of predicting and further correcting post-radiation complications, including the development of radiation burns and ulcers. Radiation skin burns are characterized by a prolonged course of the wound healing process, which is accompanied by a sharp decrease in the number of viable cells in the affected tissue from the first hours of irradiation. The type of cell death can significantly impact the effectiveness of radiation therapy and post-radiation complication correction. Therefore, it is important to study the type of their death in irradiated three-dimensional culture on a model of irradiated dermal equivalent, which is widely used today for modeling biological processes. To detect the pathways of cell death, the levels of reactive oxygen species, cell viability, number of cells undergoing autophagy, apoptosis, and necrosis, the content of active caspases 3, 8, and 9 was fluorometrically measured in the irradiated 3D cell culture by laser scanning confocal microscopy. It was determined that the transplantation of fibroblasts and keratinocytes into the irradiated dermal equivalent contributed to an increase in the overall viability of cells of the equivalent and led to a significant decrease in the concentration of free oxygen forms in the irradiated equivalent. Cells within the irradiated equivalent were not evenly distributed in terms of their quantity and viability, with an overall decrease in the cell count over time. A cluster of equivalent cells with significantly higher viability was formed around the transplant. At the same time, the fibroblasts of the transplant were found to be more resistant to the cytotoxic factors of the post-irradiation culture environment compared to keratinocytes. It was demonstrated that non-irradiated dermal equivalent cells predominantly undergo cell death through autophagy, irradiated equivalent cells primarily undergo necrosis, and after the introduction of the transplant, cell death predominantly occurs through apoptosis. In irradiated culture, both with and without transplantation, there is an increase in the content of effector caspase 3. Cells in irradiated culture undergo apoptosis through the mitochondrial mechanism (with a predominance of active caspase 9), while in irradiated culture with the introduction of the transplant, the receptor-mediated mechanism of apoptosis dominates (with a predominance of active caspase 8). The obtained results can be important for the development of new effective methods of therapy for radiation burns, chronic ulcers and wounds of various etiologies.

Insight into the interrelation between the structure and mechanical properties of dentin of a tooth is crucial for prevention and treatment of oral cavity diseases. The study of the structure of dental dentin is important for understanding the pathogenetic mechanisms of the spread of cariogenic microflora in progressive dental caries to the pulp and periodontium, as well as for the interpretation of the results of studies of dental dentin-adhesive materials. The in vitro research presented here involved the examination of coronal dentin in 46 intact teeth from rats, cats, dogs, and humans at various distances from the pulp chamber, with a focus on the quantity and diameter of dentinal tubules. The calculations were based on the analysis of 155 scanning electron microscope photographs of the enamel surface and pulp chamber wall. The researchers calculated the quantity and diameter of dentinal tubules per unit area, which they measured at various distances from the pulp chamber. It was found that dentinal tubules are the widest near the pulp chamber wall, where the average diameter ranged from 1.7 to 2.8 µm. The highest values were found in premolars of young humans and the lowest - in the incisors of rats. In the middle portion of the dentin, the diameter of dentinal tubules ranged from 1.0 to 13.3 µm, while at the periphery, it was 0.6–0.9 µm. The highest density of dentinal tubules per unit area was found closest to the pulp horn, and the lowest was in the enamel region. Near the pulp chamber wall, the average density of dentinal tubules ranged from 50 000 to 90 000/mm², in the middle of the dentin, it ranged from 37 000 to 50 000/mm², and at the periphery, it ranged from 10 000 to 25 000/mm². All examined teeth exhibited straight dentinal tubules, except for the rats’ incisors, which showed local irregularities. A comparison was made based on the quantity and width of dentinal tubules in the examined animals and humans.

Fungi are ubiquitous living beings present in the indoor and outdoor environment. Spores and mycelium of fungi carried by air have a great impact on ecology, the economy, in particular on agriculture, as well as on human health. It has been established that the incidence of fungal pathologies has increased rapidly over the past two decades. Fungi can cause allergies, and can be infectious agents, especially in immunocompomised people. Fungal spores are powerful sources of allergenic molecules covering a wide range of biochemical classes. Together with the fungal mycelium, they can cause the development of hypersensitivity, which is one of the most common pathological immune responses. Currently, known fungal aeroallergens are found in 3 fungal classes – Basidiomycota, Ascomycota, and Zygomycota. Therefore, the goal of our work was to determine the level of sensitivity to fungal allergens in the population of Vinnytsya region in order to prevent allergies caused by fungi. Data analysis of IgE-mediated, genuine, sensitization to fungal allergens of Alternaria (Alt a 1, Alt a 6), Cladosporium (Cla h, Cla h 8), Aspergillus (Asp f 1, Asp f 3, Asp f 4, Asp f 6), Penicillium (Pen ch), Malassezia (Mala s 11, Mala s 5, Mala s 6) and Saccharomyces (Sac c) was carried out using a component-resolved allergy diagnostics by ALEX2 test. The data of 87 residents of the Vinnytsya region aged 1 to 66 who underwent molecular allergy diagnostics in 2020–2022 were taken into account. Sensitivity to fungal allergens was observed in 20 patients or 23.0% of those tested. Among them, the highest level of sensitivity, in 15 patients or 75% of the number of sensitive individuals, was observed for the Alternaria fungus. The allergen component Alt a 1 caused high and very high levels of sensitization in 3 and 7 patients, respectively. Sensitivity to Aspergillus and Malassezia had the second highest rate: 6 patients or 30% of sensitized individuals were sensitive to these two fungal allergens. Alternaria was the most important fungal agent causing sensitization of the examined population of Vinnytsya region. Aspergillus allergens, known for their ability to cause both allergic and infectious reactions, were next in clinical importance. Cladosporium, which usually produce a highest number of spores in the atmosphere among all fungi, was characterized by low allergenicity. High levels of both specific and total immunoglobulin E can be prognostic markers of clinical manifestations of fungal allergy. This information should be taken into account for the prevention of fungal allergy among the population when creating allergy forecasts.
Peculiarities of histological structure of some organs of serotine bat (Eptesicus serotinus)

Published: February 2024

Chiroptera is the only group of mammals that is able to fly. They are beneficial for people and ecosystem they live in. In Ukraine, all species of bats are rare or endangered, in particular serotine bat (Eptesicus serotinus Schreber, 1774). So as to prevent the extinction of currently existing species of bats, it is crucial to combat their diseases, in particular improve diagnostics, including postmortem diagnostics. At the macroscopic and microscopic levels, morphology of bats has still been studied poorly, especially such of bats that live in Ukraine. Besides, knowledge of the structure of various organs of bats at macroscopic and microscopic levels is necessary for effective pathoanatomic diagnostics of their diseases. We researched the normal histological structure of some organs of E. serotinus. For this purpose, we used four corpses of this animal, which had previously died as a result of their disturbance during winter hibernation. We carried out a histological study, for which we sampled organs such as the liver, kidneys, lungs, heart, subcutaneous gland, and spleen. From the samples, we prepared histological sections and stained them with hematoxylin eosin. We described the general patterns of microscopic structure of the said organs of serotine bat. We found that microscopic structure of all the examined organs was similar to that of mammals in general. At the same time, we did observe some peculiarities of the histological structure of the studied organs, especially lungs, compared with such of other mammals, particularly: poor degree of development of the stroma, compact arrangement of parenchyma elements in the parenchyma-structure organs, large variability of sizes of alveolar lumens in the lungs. We assume that those peculiarities had emerged because of bats’ adaptation for flight. We believe that it is promising to continue research of microscopic structure of various organs of E. serotinus, as well as other bats living in Ukraine and around the globe.

Calcium propionate, as an approved food additive, is widely used as a mold inhibitor in food and feed. It is recognized as safe, but when metabolized in the gastrointestinal tract, it can affect the body’s metabolism both directly and indirectly through the intestinal microbiota. The effect of various doses of calcium propionate on the body of model animals, with the study of the quantitative and qualitative composition of their intestinal microbiome, was investigated in this experiment. Four groups of male laboratory rats were formed, which for 20 days consumed: a high-fat diet with the addition of 0.0%, 0.5%, 1.0%, 2.0% calcium propionoate. We determined changes in body weight, the condition and mass indices of the internal organs, biochemical blood parameters, the functional state of the nervous system using the “open field” method, as well as changes in the intestinal microbiota. Adding calcium propionate to a high-fat diet does not affect the rate of animals’ weight gain, nor the amount of feed and water consumed. High dose consumption of calcium propionate caused a decrease in the relative weight of the spleen and an increase in the relative weight of the kidneys, without affecting the functional state of the nervous system. With the addition of calcium propionate to a high-fat diet, only minor changes in some biochemical blood parameters were observed (increased De Ritis ratio and Ca/P ratio, moderate dyslipidemia). Calcium propionate had the most significant changes in the quantitative and qualitative composition of the intestinal microbiota in laboratory rats. Among the representatives of the microflora, the most sensitive to this substance against the background of a high-fat diet were obligate microorganisms from the genera Bifidobacterium and Lactobacillus. The antimicrobial action of calcium propionate was also demonstrated by the pathogenic Staphylococcus aureus. Amid a deficiency of obligate microflora, proliferation of transient microflora was found – facultative anaerobic and aerobic microorganisms (bacteria of the genera Klebsiella, Enterococcus, Clostridium, fungi of the genus Candida). Further research will be aimed at studying the effect of calcium propionate in various doses on the biological systems of different age group laboratory animals in a long-term experiment.

A partir de dezenas de entrevistas realizadas sobre incômodos musicais, o artigo discute as dimensões afetivas e os efeitos da música ambiente em variados espaços sociais, destacando que a música ambiente muitas vezes produz sensações desagradáveis e até mesmo afugenta determinadas pessoas de tais locais.
Archäologie und Republik - Interview mit Erna Diez (1913-2001) aus dem Jahr 1999
Authors: Zavadil Michaela
Published: February 2024

Politische, soziale und kulturelle Umstände sowie Veränderungen wirken sich auch auf die Wissenschaften aus. Im Bereich der Archäologie wurde diesen Einflüssen bislang nur wenig Beachtung geschenkt, und erst seit jüngerer Zeit widmet man sich verstärkt diesem Themenkreis wie auch dem Studium der eigenen Geschichte, wobei die Aufmerksamkeit oftmals auf die Zwischenkriegszeit und den Zweiten Weltkrieg gerichtet war. Im Unterschied dazu war die anlässlich des 100jährigen Jubiläums der Gründung der Republik Österreich organisierte Konferenz „Archäologie und Republik. Reflexionen zur Archäologie in Österreich in der Ersten und Zweiten Republik“ in erster Linie der Arbeit österreichischer Archäolog:innen seit 1918 gewidmet, ohne jedoch das Hauptaugenmerk auf die Zeit des Nationalsozialismus zu legen. Der Bogen der Beiträge spannt sich von Grabungen im Inland bis zu Arbeiten österreichischer Archäolog:innen in Ägypten und im Vorderen Orient. Die Untersuchungen sind jedoch nicht ausschließlich der Grabungsarchäologie gewidmet: Ebenso wird beleuchtet, wie sich Institutionen wie die Antikensammlung des Kunsthistorischen Museums in Wien, das Bundesdenkmalamt und die Prähistorische Kommission der Österreichischen Akademie der Wissenschaften entwickelt und verändert haben. Weitere Schwerpunkte bilden die Vermittlung und Rezeption von Forschungsergebnissen in der Zwischenkriegszeit bzw. während des Zweiten Weltkrieges sowie die Personengeschichte. Somit bietet der Band einen schlaglichtartigen Überblick über die Vielfalt österreichischer archäologischer Forschungstätigkeit vorrangig seit der Ausrufung der Ersten Republik.

Progress in building construction requires more durable concrete with higher strength. Polymer and water reducer liquids can improve concrete strength and durability. This research aims to improve the mechanical properties of polymer-modified concrete by using anti-slip sand and silica fume to achieve more durable concrete against sulfate attack and higher mechanical properties. The study shows an increase in compressive strength from 25.7 MPa for reference mix to 45.5 MPa using 15% silica fume and 30% Anti-slip sand; tensile strength increased from 2.72 to 4.4 MPa. Flexural strength also increased, and durability to sulfate attack also increased. The study includes the increment of durability against freezing-thawing cycles for different mixes.
Depression depth impact on the stormwater hydrographs from impervious catchment
Authors: Matlai Ivan , Vovk Lesya , Zhuk Volodymyr
Published: February 2024

Method of numerical analysis of the influence of initial depression depth coupled with absolute surface roughness and with Manning's roughness coefficient onto the key hydraulic parameters of the stormwater runoff is proposed. Small highly urbanized catchment with 100% impervious cover was used in stormwater management model numerical simulations for climatic conditions of the Lviv City (Ukraine) at the return period of 1 year. An increase in depression depth from 1 to 5 mm causes reduction in the specific maximum peak runoff from 5.13∙10−3 L/(s∙m2) to 3.29∙10−3 L/(s∙m2), while the critical duration of rainfall increase from 17 min to 56 min. The dimensionless maximum peak flow rate is expressed as a two-parameter exponent function of the initial depression depth, allowing the estimation of the lower limit of this discharge for the practically significant range of the depression depth.

Development of Domestic Ship Weapons as Presented in Ship Models in the Collection of Emperor Peter the Great Central Naval Museum
Authors: Evgenia Ovsyannikova
Published: February 2024

The article attempts for the first time to consider ship models not only as sources on the history of shipbuilding in general but also on ship weapons in particular. The relevance of the work lies in the importance of preserving the material and historical heritage of the Russian fleet, and insufficient coverage in historical science of the experience of using ship models in the interests of the Navy. The Central Naval Museum has a significant collection of ship models, ship mechanisms, and naval weapons, according to which, due to the accurate transfer of appearance, design, scale, and careful detailing of the elements and parts of weapons, it is possible to study a particular period in the history of the fleet and the development of weapons. Thus, a model of a warship, being in the halls of a museum or in the storage, does not lose its function as an element of the project, while remaining a historical relic, an artifact of shipbuilding thought, and often an object of decorative and applied art. Materials stored in museums can serve practical purposes. Using these examples, new generations of Russians get acquainted with the visible chronicle of the Navy and the destinies of remarkable ships within the walls of the museum. The purpose of the article is to attract attention to objects from the museum’s collection not only of specialists in the field of naval history, shipbuilders, and design engineers but also of people interested in the fleet. The paper aims to establish a connection between the accumulated experience of ancestors and the work of contemporaries. The author used the historical-comparative method traditionally applied in historical science, which allows us to talk about the development of classes and types of ships, as well as naval weapons, in the domestic fleet. As a result of the study, the author offers a new look at widely and little-known facts from the history of our fleet and presents a modern understanding of the study of ship models. The most striking examples of such objects from the museum collection are shown.
Soviet Anti-Tank Rifle RES: Invalid Design, Gone Epoch or Management System Failure?
Authors: Alexey Isaev
Published: February 2024

The article is dedicated to one of the rare exhibits of the Museum of Domestic Military History: experimental 20-mm anti-tank rifle RES which had been designed and tested for the Red Army during the Great Patriotic War. Development, testing, and introduction to military service of this anti-tank rifle is a good sample of decision making in the Soviet State military management system. The task of research is to formulate a scientific answer to the question about the causes of delays in launching mass-production of a high-performance anti-tank rifle RES despite the Red Army infantry urgent needs for an effective anti-tank weapon. There are some hard-toexplain delays in the RES life-cycle that prevented its transition from army testing to massproduction. Teething problems of the RES were the same as in case of the mass-produced PTRD and PTRS. Insufficient armor-piercing capabilities of the PTRD and PTRS were clear for the Main Artillery Directorate that was responsible for anti-tank rifles in the Red Army. Despite the interest of high-ranking and well-known as a soviet repressive machine leader L.P. Beria in the RES project, until the war ended the high-performance rifles did not reach the battlefields. The article describes a few factors that influenced decision making. The first one is bureaucratic delays due to the Main Artillery Directorate desire to follow the prescribed weapon life-cycle procedures after the 1941 crisis was over. The second one is objective factors connected to armor protection development of German tanks. German engineers' and military leaders’ steps to increase tanks and self-propelled guns armor-protection were really effective in view of anti-tank rifles performance. The third influence is the presence in the USSR of alternative anti-tank weapon projects by other engineering teams. The research is based on a wide range of documents.
Normative-Legal Grounds for the Organization of Disciplinary Units in the Red Army During the Great Patriotic War (1941-1945)
Authors: Andrey Levchenko
Published: February 2024

The article deals with one of the most controversial problems that attracts the attention of both professional historians and artists, namely the topic of disciplinary battalions, disciplinary companies and their servicemen in the Red Army during the Great Patriotic War of 1941- 1945. This topic is multidimensional and, without claiming to cover all or at least most of its aspects, we have focused on the study of the normative and legal foundations of the organization of disciplinary battalions and disciplinary companies. The exploration of this aspect is inevitably connected with the confrontation of facts and their analysis with various mythologems and speculations on the subject of disciplinary units in the Red Army. The author examines not only the orders of the People's Commissariats of the USSR, primarily the People's Commissariat of Defense (hereinafter - PCD), but also pre-war legislation, in particular, the Criminal Code of the Russian SFSR of 1926 and the criminal legislation of the Union republics within the USSR, which allows us to find in the pre-war criminal legislation the possibility of replacing a conviction, punishing a serviceman in wartime with imprisonment without loss of rights, with sending him to the active army, with the sentence execution being postponed until the end of hostilities. Consequently, there is a reason to assert that the normativelegal acts issued during the Great Patriotic War and, in one way or another, related to disciplinary units were adopted on the basis of and in fulfillment of the Criminal Code of the Russian SFSR of 1926 and similar codes of the Union republics. We believe that, contrary to the opinion that the creation of disciplinary units was an extremely cruel and unjustified measure of the Soviet command, this decision was dictated by the extremely difficult situation at the fronts at the height of the summer of 1942 and contributed to the strengthening of discipline both at the front and in the troops of the internal districts, i.e. was necessary and justified. The very assignment to a disciplinary unit did not mean a death sentence, either legally or actually, ; rather it gave a chance to perpetrators to be released or to have their criminal punishment commuted. The author also examines the grounds for assignment to the Red Army disciplinary units

Delayed Implant Fixture Displacement into the Maxillary Sinus Five Years Post-Loading: Unraveling the Causes - A Case Report
Authors: Cho Young Joon , Jung Yong Tak , Lee Tae Hee , Cho Hyun Woo
Published: February 2024

Reports of implant fixtures dislocating into the maxillary sinus during sinus graft procedures are well-documented. However, cases of fixtures migrating into the sinus long after placement have yet to be reported. This case report details the surgical extraction of a displaced screw and cement-retained prosthesis, including a fixture and its abutment, from the maxillary sinus after a minimum of 5 years under functional load. The extracted implant was subsequently examined using scanning electron microscopy and energy dispersive x-ray spectroscopy. We found that the migration commenced with peri-implantitis surrounding the implant, replacing the second molar. This was accompanied by a loss of cement from the crown on this implant and concurrent loosening of the abutment screw on the implant, replacing the first molar. We hypothesize that the inability of the bony tissue surrounding the second molar implant to withstand occlusal forces resulted in forming a bony sequestrum. This process ultimately precipitated the migration of the fixture, along with its abutment and adjacent necrotic bone, into the sinus cavity.
How Should We Read Maimonides’ Guide of the Perplexed? Clues From Al-Harizi’s Translation
Authors: Sadik Shalom
Published: February 2024

The objective of this scholarly article is to undertake a comparative analysis of three distinct medieval translations of the introduction to Maimonides’ “Guide of the Perplexed.” Specifically, we will examine the translations provided by Shmuel ibn Tibbon and Yehuda Al-Harizi, as well as the Latin translation. The focus of our analysis will be on two particular passages that play a crucial role in comprehending Maimonides’ intended approach to reading his work. Within the scope of this article, we will demonstrate that Ibn-Tibbon’s translation successfully preserves the essence of the original Judeo-Arabic text, thereby allowing for the interpretation of Maimonides as a radical (naturalist) philosopher. In contrast, Al-Harizi’s translation negates this potential interpretation, thereby excluding the possibility of viewing Maimonides in such a light. Notably, the medieval Latin translation aligns itself with Al-Harizi’s position and translation choices. By critically examining these translations and their respective implications, we aim to shed light on the significant impact that translation choices can have on the interpretation and understanding of philosophical texts. Ultimately, this investigation contributes to a broader understanding of Maimonides’ philosophical outlook and the challenges posed by different translations of his seminal work. The different ways of reading Maimonides’ Guide of the Perplexed is the subject of a very important and impassioned debate which has been raging from the time of the Guide’s publication until today.1 Was Maimonides a naturalist thinker who believed that religion is only needed for social and pedagogical reasons, and who based all his metaphysical opinions on philosophical argumentation? Was he a true believer who affirmed the main monotheistic and biblical positions such as creation,2 and argued for these positions against the philosophers, especially Aristotle?3 Or, perhaps he was a skeptic who doubted the possibility of humans having access to irrefutable truth?4 In seeking to answer these questions, the debate concerning the Guide condenses its focus to two major questions: 1. Is it justified for the philosophical interpreter to assume that Maimonides’ philosophical opinion is actually radical, i.e., naturalist, despite Maimonides’ explicit rejection of naturalism in the Guide (for example II:29)? 2. Does Maimonides think that humans can reach an unassailable knowledge of the secrets of religion and nature?
Classic Socialist Zionism and the Emergence of Radical Socialist Zionism in France in the 1960s
Authors: Frank Jeannine (Levana)
Published: February 2024

The awakening of Jewish identity that followed the 1967 war and the student rebellion of May 1968 brought on a major metamorphosis in the socialist Zionist Left in France. Left-wing Zionist groups at this time found themselves facing off not only against the traditional Marxist Left, with its at best ambiguous and at worst hostile attitude to Jewish nationalism, but also against a stridently anti-Zionist New Left. The result was the emergence of a new revolutionary Zionist Left that grew out of the politicization and radicalization of the younger generation during the struggle against the colonial wars in Algeria and Vietnam. Its principal agents were two members of Israel’s Marxist-Zionist Mapam party, Simha Flapan and Ely Ben-Gal, who were dispatched to Paris. Their and the party’s impact on Zionism in France at this critical juncture in the history of the New Left has long been underestimated.
Zionism and the New Left: The Mordechai Anielewicz Brigade In Argentina in the 1960s
Authors: Klor Sebastian
Published: February 2024

The New Left challenged Argentina’s Jews, both young and old, who in the 1960s numbered more than 300,000. It compelled them to reexamine and redefine ethnic-Jewish, national, and transnational elements of their collective identity. On the theoretical level, the New Left raised intriguing questions that have been a focus of attention for scholars of Latin American Jewry in general and Argentinian Jewry in particular, as well as for writers on hyphenated identities. The scholarly debate revolves around the relative weights of the ethnic-Jewish and general-national civic components of the collective identities of Jews of each specific country. Are they Latin-American Jews or Jewish Latin-Americans?1 The question has been the impetus for a historiographical debate between scholars in two different fields – Jewish studies and Latin-American studies. The former stress the particularistic aspects of the Jewish experience in Latin America. The latter, in contrast, seek to understand the Jewish experience in this region from a Latin-American standpoint. The different approaches taken by these writers and the resulting debate have, over the last three decades, produced a wide-ranging and rich research literature on issues such as ethnicity, identity, and diaspora.
O uso do RPG como proposta didático-pedagógica para trabalhar o atraso da linguagem infantil
Authors: Cardoso Brayna , Lima Kethellen
Published: February 2024

O Role-Playing Game (RPG), traduzido como “jogo de interpretação de personagens”, visa a interpretação de personagens em meio a um cenário preestabelecido, estimulando a criatividade e motivando o desenvolvimento cognitivo e linguístico de seus jogadores, por se tratar de um jogo que necessita do cumprimento de regras e da interação entre os participantes. Desta feita, pensou-se no uso do RPG como proposta didático-pedagógica a ser usada em prol ao desenvolvimento linguístico infantil e para se trabalhar o Atraso do Desenvolvimento da Linguagem Infantil (ADL), uma vez que este atraso afeta o desenvolvimento linguístico e cognitivo das crianças, visto que o ADL é considerado como uma disfunção diretamente relacionada à aquisição e desenvolvimento linguístico da criança, englobando o desenvolvimento progressivo tido como ideal para cada idade da criança, evolução de seus domínios linguísticos, capacidade cognitiva, aquisição de fonemas específicos para cada idade, entre outros fatores. O jogo foi elaborado para crianças com idades entre 4 e 5 anos, visando combater o atraso da linguagem infantil, incentivar a criatividade e a imaginação das crianças, assim como desenvolver aspectos ligados à sua cognição, que influenciam diretamente nos aspectos de linguagem, objetivando aguçar o processo de criação de narrativas, as quais são elaboradas valendo-se da memória e sequenciação de fatos que são socializados entre os jogadores. Para realização deste artigo, buscou-se suporte teórico-metodológico nas concepções de Vygotsky (1993); Del Ré (2006); Scarpa (2001); Koch e Cunha-Lima (2007); Pilati (2017); Lucena e Sabini (2005). Para assim poder elaborar o jogo pedagógico, de acordo com a necessidade socioescolar das crianças, visando o fomento da interação social, a maturação dos elementos linguísticos, por meio de jogos ludopedagógicos, e proporcionando possibilidades práticas aos profissionais da área para se trabalhar a dinâmica do ensino-aprendizagem no processo de aquisição da linguagem.

Authors: Kaur Kawaljit , Jewett Anahid
Published: February 2024

Despite advancements in the field of cancer therapeutics, the five-year survival rate remains low in oral cancer patients. Therefore, the effective therapeutics are needed against oral cancer. Also, several studies including ours, have shown severely suppressed function and number of NK cells in oral cancer patients. In this review, we discuss the approach to inhibit the tumor growth and metastasis by direct killing or NK cell-mediated tumor differentiation. This review also provides an overview on supercharging NK cells using osteoclasts and probiotic bacteria, and their efficacy as cancer immunotherapeutic in humanized-BLT mice.

Authors: Tkachenko P. V.
Published: February 2024

The species composition of marine fish species occurring in the Dnieper estuary is given in the paper. During the 30-year period of ichthyological research (1992-2021), 22 marine fish species were found in this estuary, and one more species was noted 60 years ago. Totally, eight fish species (36.4%) were recorded in this water body for the first time, of which six species (75.0%) were registered in the last 5-8 years, when sea water inflow to the estuary extended. The degree of occurrence of marine fish species in the Dnieper estuary and their classification by movement activity, types of reproduction, feeding, habitat, and zoogeographical origin were established. The penetration range of each species deep into the estuary is shown. The marine fish species that are mass and common here are identified.Anumber of species that are very rare in the Black Sea in general, including those listed in the Red Book of Ukraine, were found in the studied water body. The catastrophic events at the Kakhovka Hydro-Electric power Station are practically relevant to the material of the article due to possible drastic changes in the fish fauna of the Dnieper estuary in the coming years.

In this article, a low-profile multiband asymmetrical psi-shaped antenna for different wireless applications is presented and analyzed. This multiband antenna consists of an asymmetrical psi-shaped radiator considered on a single layer FR4 substrate with compact dimensions. The better impedance matching characteristics between the radiating element and the signal source are obtained by employing a slotted structure. The designed antenna operates at six different frequency bands of 1.8-2.03 GHz [GSM1800, personal communication systems (PCS)], 4.64-5.35 GHz [wireless local area network (WLAN)], 6.05-6.95 GHz (C-band), 7.92-8.59 GHz (military), 9.55-11.14 GHz [fixed satellite service (FSS)], and 11.57-12.29 GHz (DBS) while the S11 value is lower than -10 dB. The Ansoft HFSS 21 electromagnetic simulator is employed to optimize the antenna dimensions and study the antenna functionality at the six different frequency bands. The designed antenna exhibits higher gain at six frequency bands. The developed multiband antenna is prototyped, and test results are generated to validate its performance. The simulation results authenticate acceptable agreement with the measurement results. This antenna is a good choice for GSM1800, PCS, WLAN, C-band, FSS, and military defense applications.
SMALL-SCALE MIMO ANTENNA WITH HIGH ISOLATION FOR 5G COMMUNICATION
Authors: Choudhary Dilip Kumar , Ali Tanweer , P. Rajendra Prasad , Ahmad Roshan Zameer
Published: February 2024

This manuscript describes two- and three-element small-scale multiple-input multiple-output (MIMO) antenna configurations for 5G communications ranging from 23.5 to 28.6 GHz. Modern device antennas have two essential features: isolation and a larger bandwidth. In this regard, firstly a single element antenna has been designed using quarter wavelength impedance transformer and semi-circular loaded patch along with defected ground structure. Furthermore, two single-element antennas are placed orthonormal to each other having quarter wavelength distance from the center of the single-element antenna. To increase the bandwidth and isolation, additionally a rectangular patch and strip isolate from ground. This structural change alters the current path, improving the impedance matching and isolation of the two-element MIMO antenna configuration. After that the three-element MIMO configuration was formed by placing two single-element antennas orthogonally at quarter wavelength from the center of the single-element antenna. The total size of two- and three-element MIMO antenna is 15 × 11 × 1.6 mm and 20 × 11 × 1.6 mm, respectively. The proposed MIMO antennas provide isolation of more than 21 dB and gain more than 25 dB throughout the working band. MIMO diversity features function reasonably well, with an envelope correlation coefficient of less than 0.002 and diversity gain of 10. Proposed antennas can be a good candidate for MIMO applications in the 5G communication frequency range 2 (FR2), 28 GHz bands.

Nationalization and the formation of a national state structure in the countries of Central Asia arose initially with the emergence of ethnic identity. The formation of ethnic identity in the countries of Central Asia is a process that began during the Tsarist era and was ultimately completed mainly during the Soviet Union. The formation of ethnic identity is the most important factor in social modernization in Central Asia. Since the formation of ethnic identity is an absolutely modern phenomenon. Modernization in Central Asia, in fact, was implemented in a top-down fashion. The rise of nations was carried out through the nation states developed by the Soviets. In other words, the nation states created during the period of the Union of Soviets in Central Asia are also creators of nations in the modern sense of the word.
Stuttgart 1975, Heinz Schlaffer

Published: February 2024

«The past is a foreign country», heißt es am Eingang eines eigentlich nur für diesen Satz berühmten Romans – «they do things differently there.» Mein Versuch, den untergegangenen Kontinent namens «Universität Stuttgart 1975, Amtsantritt Professor Heinz Schlaffer, 36 Jahre alt» aus der Erinnerung und den vergilbten Seiten meiner Tagebücher heraus wiederauferstehen zu lassen, verursacht Herzklopfen. Denn nicht nur eine persönliche Antike kommt herauf. Ich sehe zugleich auch in einen Abgrund erfahrener Geschichte, die unbarmherzig zurückschaut. Wir sind heute fast zwei Jahrzehnte weiter von 1975 weg, als dieses Jahr von der Zerstörung Stuttgarts am Ende des Weltkriegs entfernt gewesen ist.
