The Evolution of Durable, Implantable Axial-Flow Rotary Blood Pumps
Authors: Smith P. Alex , Wang Yaxin , Frazier O.H. 
Published: April 2023

Abstract
Left ventricular assist devices (LVADs) are increasingly used to treat patients with end-stage heart failure. Implantable LVADs were initially developed in the 1960s and 1970s. Because of technological constraints, early LVADs had limited durability (eg, membrane or valve failure) and poor biocompatibility (eg, driveline infections and high rates of hemolysis caused by high shear rates). As the technology has improved over the past 50 years, contemporary rotary LVADs have become smaller, more durable, and less likely to result in infection. A better understanding of hemodynamics and end-organ perfusion also has driven research into the enhanced functionality of rotary LVADs. This paper reviews from a historical perspective some of the most influential axial-flow rotary blood pumps to date, from benchtop conception to clinical implementation. The history of mechanical circulatory support devices includes improvements related to the mechanical, anatomical, and physiologic aspects of these devices. In addition, areas for further improvement are discussed, as are important future directions—such as the development of miniature and partial-support LVADs, which are less invasive because of their compact size. The ongoing development and optimization of these pumps may increase long-term LVAD use and promote early intervention in the treatment of patients with heart failure.
Interkulturowość w wybranych podręcznikach do nauki włoskiego i angielskiego języka biznesu i ekonomii. Studium porównawcze
Authors: Ozimska Joanna 
Published: April 2023

This article attempts to characterize three textbooks for learning the language of business and economics in terms of the presence of elements developing intercultural competences. Two textbooks for learning Italian and one for learning English were analyzed: (1) Italiano per economisti, (2) L'italiano in azienda, (3) Market Leader. Intermediate business English. The above-mentioned titles were published in the years 2002-2003, which allowed to eliminate possible differences resulting from the changing over time approach to the phenomenon of intercultural language education.
The aim of the study is to identify the elements developing intercultural competences, their qualitative and quantitative characteristics, to discuss the differences in the approach in Italian and English-language texts and to indicate the possibility of using selected solutions in the new teaching materials. This is important as research shows that contacts with foreign cultures alone do not naturally lead to the development of intercultural competence (Sobkowiak, 2015: 64, Budzanowska-Drzewiecka and Motyl-Adamczyk, 2016: 56).
The analysis covered non-verbal communication (gestures), stereotypes, proverbs and sayings, rules of linguistic politeness. From the glottodidactic point of view, the proposed types of exercises and the connection of (inter)cultural competences with other communicative competences will be analyzed.
The main hypothesis verified during the analyzes assumes that the concept of intercultural language education, although it does not appear as a notion on the pages of textbooks, is an important component of the didactic process in materials for learning the business language, and the approach to interculturality may differ depending on the target culture and status of the foreign language taught (Italian vs English, modern lingua franca).
“Kongqi” Theory and the Aesthetic Spirit of Chinese Film
Authors: Li Daoxin 
Published: April 2023

Abstract
Based on the traditional Chinese “kong view” and “qi view” of classical literature and art, this article aims to further construct localized Chinese film theory, by combining methods and approaches to media archeology, and comparing Chinese and foreign literary aesthetics and film art poetics. The ancient Chinese word “dianying” (electric shadow) basically carries the same connotations as the modern word “cinema”, which is internally connected. The “kong view” (empty) and the “qi view” constitute the Chinese aesthetic foundation for the “kongqi” (atmosphere) theory of Chinese film. This theory has been nourished by western aesthetics since the 1920s, absorbing both film spirit theory and film art poetics. With exchanges and dialogues between ancient and modern language, and between China and other countries, this article examines the ways in which the “kongqi” (atmosphere) theory has nurtured a large number of outstanding Chinese film authors, and highlights the aesthetic spirit of “One World One Qi” that is perceived in Chinese films.
Some results for a p(x)-Kirchhoff type variation-inequality problems in non-divergence form
Authors: Dong Yan 
Published: April 2023

Abstract
The author of this article concerns with the existence, uniqueness, and stability of the weak solution to the variation-inequality problem. The Kirchhoff operator is a non-divergence form with space variable parameter. The existence of generalized solution is proved by the Leray-Schauder principle and parabolic regularization. The uniqueness and stability of the solution are also discussed by contradiction.

Environmentally friendly bioameliorant to increase soil fertility and rice (Oryza sativa) production
Authors: Simarmata Tualar , Prayoga Muhamad Khais , Setiawati Mieke Rochimi , Adinata Kustiwa , Stӧber Silke 
Published: April 2023

Abstract
Soil nutrients can be reduced because of global climate change. This is because climate change causes high rainfall intensity and a prolonged dry season. Efforts to overcome this are fertilized using bioameliorants so that soil nutrients remain available for plants. Observations have been made from May to August 2018 at the JAMTANI Field Laboratory. The study used a factorial randomized block design with three replications. The first factor was a bioameliorant (P1 = goat manure 10 tons ha−1; P2 = goat manure 10 tons ha−1 + Azolla pinnata 10 tons ha−1; P3 = goat manure 10 tons ha−1 + Sesbania rostrata 2 tons ha−1; dan P4 = goat manure 10 tons ha−1 + A. pinnata 5 tons ha−1 + S. rostrata 1 tons ha−1) and the second factor was rice varieties (Ciherang and Mendawak). The application of bioameliorant increased C-organic of soil by 9.04% to 20.41% and soil nitrogen by 11.76% to 38.24%. The addition of bioameliorant did not cause differences in the weight of the plant between the Mendawak variety (61.34 g) and the Ciherang variety (56.96 g). The most efficient addition of bioameliorant is P3 (goat manure 10 tons ha−1 + S. rostrata 2 tons ha−1) with nutrient uptake efficiency value reaching 5.77%. The use of bioameliorant is expected to be able to substitute the use of inorganic fertilizers and increase rice production.
Vorbereitet auf die Zeitenwende?
Authors: Burilkov Alexandr , Rieck Christian E. 
Published: April 2023

Kurzfassung
Dieser Beitrag befasst sich mit der Einsatzbereitschaft der Bundeswehr, sich an Auslandseinsätzen im gesamten Konfliktspektrum beteiligen zu können. Vor dem Hintergrund der „Zeitenwende“ werden drei Konflikte unterschiedlicher Intensität in der Ukraine, Afghanistan und Mali untersucht. Er bewertet sodann das Leistungspotenzial der Bundeswehr und gibt Empfehlungen für den Fähigkeitenaufbau: Neben der Modernisierung des Panzer- und Artilleriedispositivs fehlen vor allem Drohnen zur Fernaufklärung und als verharrende Waffen sowie eine wirksame Luftunterstützung – die jedoch in zwischenstaatlichen Konflikten hoher Intensität nur eingeschränkt einsetzbar sein wird.
Historische Esoterik als Erkenntnismethode. Wie russische Pseudo-Wissenschaftler zu Moskaus antiwestlicher Wende beigetragen haben
Authors: Umland Andreas 
Published: April 2023

Kurzfassung
Eine Reihe parawissenschaftlicher Tendenzen in der russischen Sozialwissenschaft hat zur Vorbereitung des Ukraine-Krieges beigetragen. Neben den Propaganda- und Desinformationskampagnen des Kremls ist eine intellektuelle Deformation der russischen Elite durch manichäische Ideen von Theoretikern wie Lew Gumiljow und Alexander Dugin mitverantwortlich für die zunehmende Abspaltung Russlands von Europa. Spekulative, oft verschwörerische, teils okkultistische und rassistische Theorien haben den öffentlichen Diskurs im postsowjetischen Raum infiziert und ihre Verfechter haben anerkannte Sozialwissenschaftler und Historiker aus intellektuellen und medialen Debatten verdrängt. Dieser öffentliche Diskurs ist seit Beginn von Glasnost vor 35 Jahren zu beobachten und ein Bestimmungsfaktor für den russischen Angriff auf die Ukraine im Jahr 2014 geworden.
Welche Friedenslösungen für den Russland-Ukraine-Krieg? Gedanken zu Strategien des Friedenschließens
Authors: Heuser Beatrice 
Published: April 2023

Kurzfassung
Vor allem in der deutschen Diskussion über Russlands Angriffskrieg gegen die Ukraine werden immer wieder Forderungen nach diplomatisch verhandelten Kompromissen zur Kriegsbeendigung laut. Verschiedene Möglichkeiten sind vorstellbar, doch hat keine das Potenzial, die Basis für einen halbwegs dauerhaften Friedensschluss zu bilden. Schaut man sich die Geschichte der Beendigung europäischer Kriege an, so zeigt sich, dass in der Konfrontation mit einem derart nationalistisch und kompromisslos auftretenden Akteur wie Russland der einzige Weg zu einem beständigen Frieden ein Regimewechsel ist. Dieser kann und darf nicht von außen bewirkt werden. Daher ist in diesem Fall eine Politik der Gegenmachtbildung des Westens vorerst die einzig verbleibende Strategie.
In Vitro Mutagenesis of Dendrobium gabriella suryajaya Using Ethyl Methane Sulfonate (EMS) and Plantlet Regeneration

Published: April 2023

Plant breeding through mutation techniques has the main purpose to explore genetic diversity in the presence of useful traits for developing new plants. Ethyl Methane Sulfonate (EMS) is a widely used chemical to induce mutations in plants focused on obtaining genetic variation. EMS can induce random points of mutations and some of which can create new stop codons in the desired gene. EMS has been successfully used to generate morphological diversity and encourage the improvement of desired traits. The 3-month-old Dendrobium gabriella suryajaya Orchid protocorm-like bodies (PLB) treatment with EMS concentrations of 0.025%, 0.05%, and 0.075% can change genetic diversity, especially in leaf morphology. A total of 105 orchids were soaked in EMS solution at concentrations for 12 and 24 hours respectively. The phenotypic variations observed in this population include changes in leaf color and the number of buds. This EMS mutant population will be used for further studies including screening for various traits such as through ISSR analysis to determine the level of diversity. This research shows that mutagenesis using EMS can produce the amount of variability in Dendrobium. The generation of variability for desired traits resulted in the identification of several mutants with important agronomic characteristics that can be used as germplasm for improvement.

Published: April 2023

Introduction: Traumatic fractures of the sternum are relatively rare injuries and occur against the backdrop of high-energy chest trauma. The severity of these lesions is mainly related to their association with life-threatening cardiovascular lesions. Their treatment is mostly conservative. The aim of this work is to report the results of the management of post-traumatic fractures of the sternum in Niger. Patients and methods: a 27-month retrospective study involving 9 patients with a post-traumatic fracture of the sternum treated at the thoracic surgery department of the General
Reference Hospital of Niamey. 8 of these patients were treated with conservative methods and 1 benefited from osteosynthesis by a screwed ankle plate adapted to the sternum. Results: The mean age of patients was 41.78 years (14 to 60 years). The male sex was predominant with 7 cases or 77.77%. Public road traffic is the most common occurrence circumstance found in 88.9% of cases. Symptomatology was dominated by presternal chest pain. The site of the fracture was at the level of the manubrium in 66.6% of cases and the most common type of fracture was the simple fracture in 55,56 of cases. Pulmonary contusion and hemothorax were the most associated lesions with respectively 44.4% each. There was 1 case of death in the context of polytrauma. Conclusion: Post-traumatic fractures of the sternum are rare and potentially serious, requiring multidisciplinary management.
Między zawodem a służbą. O pracy pracownika socjalnego z osobami starszymi w perspektywie etyki personalistycznej
Authors: Stachurski Michał 
Published: April 2023

Wobec wyzwania, jakim jest proces starzejącego się społeczeństwa (zwłaszcza w Europie), wydaje się słuszne podjęcie tematu dotyczącego roli pracownika socjalnego wobec osób starszych. Zagadnienie to rozważane jest w aspekcie etycznym, w oparciu o współczesne trendy wypracowane na gruncie utylitaryzmu i personalizmu. W artykule kładzie się nacisk głównie na personalizm, który pozwala spojrzeć na opiekę nad starszymi z punktu widzenia osoby, podmiotowości, godności i odpowiedzialności, obowiązków zawodowych i służby; pozwala dowartościować pozycję starszych w strukturze społecznej, a także docenić pracę na ich rzecz.
Utopia anielska jako wzorzec społeczności ziemskiej w myśli Pseudo-Dionizego i Tomasza z Akwinu
Authors: Tomasiewicz Marcin 
Published: April 2023

Artykuł porusza zagadnienie wpływu nauki o aniołach Pseudo-Dionizego Areopagity i Tomasza z Akwinu na filozofię społeczno-polityczną w średniowieczu. Kluczowym pojęciem, którym posługuje się angelologia Pseudo-Dionizego jest „hierarchia”. Koncepcja hierarchii jest osadzona na założeniach metafizyki neoplatońskiej, stąd też Pseudo-Dionizy przedstawia byty anielskie w porządku enneadycznym. Tak przedstawiona hierarchia wywarła wpływ na rozumienie i uzasadnienie porządku społecznego w wiekach średnich oraz na legitymizację struktury władzy politycznej. Wreszcie, wedle wymienionych autorów głównym celem społeczności anielskiej jest jedność stworzenia w Bogu. Tym samym również idealny porządek polityczny ziemski musi realizować cele eschatologiczne.

Published: April 2023

Reading and writing skills play essential roles in second language teaching and learning. The objective of the present study is to investigate the effect of extensive reading on the writing performance of freshmen students at the University of Jordan. In order to achieve the aim of the study, 16 students were chosen as a convenient sample from freshmen students. This group of students were exposed to extensive reading texts over the period of one and a half month. Data of the study were collected via a writing pretest and posttest. The pretest was conducted prior to the application of the treatment. A paired samples test was used as a statistical test. The findings of the study showed that there is an improvement in the writing performance of the group. This resulted in the rejection of the null hypothesis, indicating that the extensive reading may have a significant positive effect on the writing performance of freshmen.
[Between] the Paintings of the Ndebele Houses: [Geo]metries and Ragged Curricula
Authors: Machado Paulucci Eric , Tamayo Osorio Carolina , De Godoy Domingues Marcelo 
Published: April 2023

The implementation of Law 10.639/2003 on the Teaching of Afro-Brazilian History and Culture in Schools has demanded from Mathematics Education several studies and problematizations about the nature of the [M]mathematical knowledge present in school curricula. This Law prompts dialogues between different epistemologies, whether of Western origin, Afro-Brazilian origin, or in between these epistemologies, in order to produce new debates that fray the disciplinary logic, neutrality, universality, and uniqueness of Mathematics. Thus, based on the practice of painting houses, which is carried out by women from the Ndebele people of Africa, we can consider the curriculum a place of invention. Objectives: Learning from the Ndebele women, what paintings can emerge? Are curricula invented when Stories and practices of African cultures become the focus of study in Mathematics classes? Design: We are guided by an intervention-research, performing a review of ethnographic investigations on the sociocultural practice of painting Ndebele houses. Environment and participants: The research begins with the subjectivity processes that cross three researchers: two mathematical educators in different stages of life and a philosopher. They are all interested in following different paths with Mathematics Education, Ethnomathematics, Philosophy, and..., which make us professors, determining our conceptions of territory and research. Data collection and analysis: The records and data of this research were produced based on the works of Paulus Gerdes on the paintings of Ndebele houses, as well as other authors of African origin, allowing us to be affected by these productions and question the homogeneous curricular models. Results: With this research, we travel to Africa to find strange the mathematicS practiced by the Ndebele community and to make the mathematics curriculum strange; in this sense, contemplating knowledge at the crossroads of the school curriculum, Law 10.639/2003 and Mathematics, entails producing a notion that is closer to the affective field than the field of meanings. Conclusions: The experience of shifting sociocultural practices to the classroom, such as the sociocultural practice of painting Ndebele houses reveals a curriculum as a place of invention in which mathematicS takes place and composes other curricula capable of painting a different use for Law 10.639/2003 fraying Mathematics' neutrality, universality, and uniqueness, and developing a school curriculum that escapes, leaks, and spreads minor, distinct, and unusual knowledge.
Yoga and Mindfulness Intervention for Concussion Recovery
Authors: Devore Elizabeth , Morgenlander Andrea , Krucoff Carol , Morgenlander Joel 
Published: April 2023

Abstract
Concussion imposes a substantial global health burden, and few evidence-based treatments that approach concussion treatment holistically are available. Moreover, early intervention is important before concussion symptoms become chronic and more refractory to treatment. In this pilot study, we evaluated the tolerability of a protocol called Mindfulness and Yoga for Treatment After Concussion (MYTAC), which was specifically designed for individuals with concussion. We also explored the possible benefit of the MYTAC protocol for concussion recovery. Participants were 15–60 years old with recent concussion and had presented to selected practices within a university health system. Participants used the video-based MYTAC protocol for 5 consecutive days and reported concussion symptoms on an abbreviated version of the Sports Concussion Assessment Tool version 3 (SCAT3). We compared the abbreviated SCAT3 scores across the intervention period, including immediately before and after each yoga session, using standard statistical methods for paired data. Of 25 participants enrolled in the study, 15 completed the MYTAC protocol and 1 completed 2 days of the protocol before withdrawing due to worsening symptoms; the remaining 9 participants did not complete the protocol. On average, total abbreviated SCAT3 scores decreased by 9.9 ± 7.6 points, or approximately 50%, over the intervention period (from an initial value of 18.8 ± 6.7 points prior to the yoga protocol).
Although this pilot study had significant methodological limitations, we concluded that the MYTAC protocol had fair tolerability and possibly a beneficial effect on concussion recovery. However, future interventions should evaluate this protocol in larger, more rigorously designed studies.

Highlights. The article describes the contribution of foreign and Russian surgeons to the development of aortic valve replacement using autologous tissue, and presents the evolution of the technique. The authors tried to answer the question whether the Japanese professor S. Ozaki actually developed something new or the discovery was already made 40 years ago. At the end of the article, the technique developed by a Russian cardiac surgeon is presented, casting doubt on the use of templates in this procedure.Abstract. Aortic valve replacement using autologous pericardium (neocuspidalization) is becoming an increasingly attractive option that can be applied to a wide range of aortic valve diseases. This technique avoids the need for lifelong administration of anticoagulant drugs, and provides the maximum effective orifice area, resulting in a low transvalvular gradient. The new technique, introduced by Shigeyuki Ozaki, has made the procedure more reproducible with promising medium- and longterm results. But is Ozaki the predecessor of this technique or is “all new is well forgotten old”? This review focuses on the historical aspects of the development of neocuspidalization of the aortic valve using autologous pericardium, the first interventions for valve reconstruction are mentioned, the evolution in the technique of preparation and fixation of the leaflets is reflected.
