Authors: Slavchev G. , Mileva N. , Dacheva A. , Mekov E. , Dzhambazov S. , Vassilev D.
Published: July 2023

Introduction: Fractional fl ow reserve (FFR) implies the ratio of the maximal hyperemic myocardial blood fl ow in the case of a pathologically changed coronary artery to the maximal hyperemic myocardial blood fl ow in the case of a healthy coronary artery. Aims: The aim of the current study is to perform an economic evaluation and budget impact analysis of measuring FFR as a medical activity in Bulgaria. Material and Methods: For the purpose of the current analysis, two models using Microsoft Excel and TreeAge Pro were developed to evaluate the cost-effectiveness of the FFR-guided percutaneous coronary intervention (PCI) compared to the classic angiography-guided PCI in patients with ischemic heart disease (IHD) with one-vessel coronary artery disease (CAD) or multivessel CAD. The analysis will focus on the health perspective and the payer perspective - National Health Insurance Fund (NHIF). Results: The medico-diagnostic activity related to measuring FFR in patients with multi-vessel coronary artery disease is shown to be a cost-effective therapeutic approach in Bulgaria compared to the angiography-guided PCI (ICER = 50 456 BGN/QALY) with a cost-effectiveness threshold of 51 510 BGN/QALY. FFR- guided PCI strategy in one-vessel coronary artery disease patients is a cost-saving approach (-853 BGN) when compared to the angiography-guided PCI (4 150 BGN). Conclusion: Budget impact analysis revealed that the FFR-guided PCI strategy is a cost-saving alternative approach to the angiographyguided PCI. The savings of the NHIF during the fi rst year of reimbursement of FFR would be -1,1 million BGN and could reach -1,6 million BGN in the third year.
Unraveling the mystery of Takutsubo cardiomyopathy: a descendant of COVID-19 heart syndrome
Authors: Kanuri S. , Sirrkay P. J.
Published: July 2023

Takutsubo, or stress cardiomyopathy (TCM) is one of the important cardiovascular disorders encountered during the COVID-19 pandemic. We performed a PubMed search of relevant articles and presented this review which included epidemiology, etiopathogenesis, diagnosis and treatment of this clinical disorder. Takutsubo is usually more common in women than men. COVID-19 infection or vaccination can incite severe emotional disorders such as anxiety and depression, which flames up impaired neural networks in the limbic system. This stirs up disorganized regulation of autonomic nervous system with predominance and excessive firing of sympathetic nervous system to the ventricular myocardium. Moreover, direct invasion and systemic effects of COVID-19 infection including hormonal influences, autoimmunity, cytokine storm and neighboring infections might also play a significant role in the manifestation of this disorder. It commonly presents signs and symptoms of left ventricular dysfunction. Although most cases are undergoing remission within a few weeks, complications such as LV outflow tract obstruction, thromboembolism and arrhythmias were also reported. Since clinical symptoms are non-specific, a high degree of clinical suspicion is warranted particularly with the co-existing COVID-19 infections. Clinicians often leaned upon battery of tests including ECG, echocardiography and CMR to rule out myocarditis and coronary artery disease. Supportive management including treatment of heart failure and any associated arrhythmias and thromboembolism. Recurrences are common, but the treatment of underlying psychiatric disorders, including relaxation techniques, is the key strategy to avoid future occurrences.

The study examined the impacts of herdsmen insurgencies on food stuff supply and sustainability in Nigeria. The specific objectives are to: (i) investigate the major cause(s) of herdsmen attack on farmers in some parts of the country; (ii) examine the extent to which herdsmen attack affects the farmers, market women, individual and the economy of the country, (iii) examine the major factors responsible for herdsmen /farmers conflicts and (iv) investigate the extent in which the impart of herdsmen/farmers conflicts affects farmer’s savings. The methodology was through direct participation, structured questionnaire and focus group discussion. Those that were interviewed include: farmers, drivers, market women and individual through purposive sampling technique. A total of 300 copies of questionnaire were administered but 285 were found usable for this study. The analyses were both descriptive and inferential. Findings show that causes of herdsmen/farmers conflict have 35.8% (0.358) explanation on food supply and sustainability in Nigeria. The f-statistic value 20.772 with p-value 0.000 implied that crop damage by cattle encroachment; pollution of water points by cattle; domineering nature of the herdsmen; poor government policies; cattle rustling; affects food supply in Nigeria. The study however recommended that Governments should promulgate legislations outlawing open grazing of cattle while encouraging herders to establish ranches for their cattle, Government should also fish out the herdsmen sponsors who procure them with guns and other ammunitions to be carrying about and prosecute them and finally, State governments should designate some areas as grazing fields for the nomadic herdsmen and make them pay tax to the state, whilst warning that any crime involving a Fulani herdsman would attract severe penalties. This will drastically curb their excesses

Authors: Stephen Hahlani Onismo , Chigora Tendai Blessing , Hove Blessing
Published: July 2023

This qualitative study analysed the implementation of Professional Learning Communities (PLCS) for quality teaching of Design Technology (DT) in the Zimbabwean high schools. The study was triggered by low uptake of the Design Technology curriculum since its inception in 2015 by public schools. The study included seven Design Technology secondary school teachers that were randomly selected from the secondary schools in the country’s selected district cluster. Data was collected from the respondents through face to face interviews, critiquing, comparing and contrasting related literature. The social cognitive theory, Bandura’s social learning theory and Vygotsky’s social constructivism theory guides and informs the analysis of findings of this study. Findings shows that the Design Technology syllabus is comprehensive, teachers lack the relevant training to handle the comprehensive syllabus, low investment in staff development programs and low engagement in staff professional groups. The study recommends that regular staff development workshops be administered for Design Technology Schools, equip workshops with tools, teacher training in the comprehensive syllabus and engage in collaborative activities with other DT teachers in country and far wide to guarantee quality teaching of the learning area in the secondary schools.

Published: July 2023

Con el propósito de generar información objetiva sobre la composición y estructura general de la educación científica salvadoreña en los niveles de primaria y secundaria, ante la ausencia de fundamentos curriculares específicos y en el contexto de un currículo heterogéneo, se diseñó un método cuantitativo que emplea los contenidos programáticos y las horas clase de las asignaturas “Ciencia, Salud y Medio Ambiente” y “Ciencias Naturales” para exponer posibles énfasis disciplinares y su articulación teórica interna. Los resultados muestran contenidos altamente explícitos y recurrentes con proporciones que sugieren alta incidencia de la educación en salud, poca relevancia de las geociencias y déficit tecnológico. Los análisis de agrupamiento perfilan seis ejes globales de contenido, con un quiebre de enfoque entre primaria y secundaria. Mientras la primaria enfatiza las ciencias aplicadas e integradas, con alta multidisciplinariedad; la secundaria promueve las ciencias puras, dejando dispersas a las ciencias ambientales. Siendo el primer análisis cuantitativo teórico de contenidos programáticos que se realiza en El Salvador, estos resultados deberán confrontarse contra futura evidencia empírica.

Learning Behind the Bars: Implications for ‘Learning-for-Development’
Authors: Akin Gulden
Published: July 2023

This study aimed to determine the learning patterns and experiences of incarcerated adults within correctional settings and how their prison learning transforms their lives after they are released. In this qualitative research, semi-structured interviews were conducted to obtain the opinions of eight formerly incarcerated people who experienced educational practices during their serving time in prison. The snowball sampling technique was used to reach the target group of the study. Thematic analysis method was used during the data analysis process. The results of the paper, which are limited to the opinions of the participants in the study, showed that the change in the educational level of the prison population had led to a transformation in group dynamics among inmates in Turkey. Although former inmates experienced a permanent transformation in their lives after attending literacy courses, they could not carry on their religious practices after being released due to the struggle to make a living. Inmates who were not interested in educational programmes within prison managed their own learning processes as self-directed learners. Moreover, although inmates are certified through vocational training programmes, they have challenges in finding jobs when they re-enter society. Educational disruptions due to Covid-19 demonstrate that it is urgent to transform the prison education system into a technologically enriched learning environment in Turkey.

Το φαινόμενου του θερμοηλεκτρισμού έχει μελετηθεί για περισσότερο από δύο αιώνες και προσφέρει έναν βιώσιμο τρόπο ανάκτησης και μετατροπής της απορριπτόμενης θερμότητας σε προσβάσιμη και διαθέσιμη ηλεκτρική ενέργεια. Οι πρώτες θερμοηλεκτρικές γεννήτριες που κατασκευάστηκαν με σκοπό την ανάκτηση της απορριπτόμενης ενέργειας χρησιμοποιούν υλικά που εξακολουθούν να παρουσιάζουν πολύτιμο ερευνητικό ενδιαφέρον, ενώ νέες ιδέες και έννοιες σχετικά με την κατανόησή μας για την ανάπτυξη, την επεξεργασία και τον χαρακτηρισμό των θερμοηλεκτρικών υλικών έχουν προχωρήσει τα τελευταία 30 χρόνια. Ως επακόλουθο, αναπτύσσονται νέες κατηγορίες θερμοηλεκτρικών υλικών, παρέχοντας νέες ευκαιρίες για τη βελτίωση της απόδοσης της θερμοηλεκτρικής μετατροπής της θερμότητας σε χρήσιμες μορφές ενέργειας. Λόγω της αυξανόμενης ζήτησης για βιώσιμες τεχνολογίες μετατροπής ενέργειας, είναι σημαντικό να αναπτυχθούν θερμοηλεκτρικές δομές με βάση διαθέσιμα, μη τοξικά υλικά που μπορούν να κατασκευαστούν σε οικονομικά βιώσιμα μεγέθη και να είναι κατάλληλα για να χρησιμοποιηθούν σε διαφορετικά θερμοκρασιακά εύρη.Η παρούσα διδακτορική διατριβή διερευνά την κατασκευή έξυπνων, πολυλειτουργικών, θερμοηλεκτρικών σύνθετων υλικών με βάση το τσιμέντο. Πιο συγκεκριμένα, η ανάπτυξη και βελτιστοποίηση των θερμοηλεκτρικών τσιμεντοειδών υλικών επιτεύχθηκε μέσω της τροποποίησης της τσιμεντοειδούς μήτρας με ενισχυτικά υλικά του άνθρακα που παρουσιάζουν διαστάσεις στην νάνο- και μίκρο-κλίμακα. Ο τύπος των υλικών του άνθρακα, το κατά βάρος ποσοστό ενίσχυσης της τσιμεντοειδούς μήτρας καθώς και τα πρωτόκολλα διασποράς αυτών βελτιστοποιήθηκαν για να διευκολύνουν την ανάπτυξη σύνθετων υλικών με βάση το τσιμέντο που παρουσιάζουν την ικανότητα συλλογής και μετατροπής της θερμοηλεκτρικής ενέργειας. Τέλος, κατασκευάστηκαν γεννήτριες θερμοηλεκτρικής ενέργειας με βάση το τσιμέντο που θα μπορούσαν να βρουν εφαρμογή για μια πιο βιώσιμη δόμηση, επιτρέποντας την τροφοδοσία ηλεκτρονικών συσκευών χαμηλής και μέσης κατανάλωσης.

Abstract. Masithah ED, Islamy RA. 2023. Checklist of freshwater periphytic diatoms in the midstream of Brantas River, East Java, Indonesia. Biodiversitas 24: 3269-3281. Periphytic diatoms are a group of microalgae that live attached to the surface of the substrate such as rocks, aquatic plants, or other objects in the water. This group has potential as an indicator of environmental quality of water because its existence is influenced by water quality, such as nutrient levels and pollution levels. They are also useful in describing the ecological state, performances, and sustainability of ecosystems because of their ability to measure various environmental parameters and correlate them with diversity, evenness, and richness. This study provides a checklist of freshwater periphytic diatoms in the midstream of Brantas River, East Java, Indonesia. The sampling and identification according to published methods were carried out at the Laboratory of Aquaculture, Faculty of Fisheries and Marine, Universitas Airlangga, Surabaya. This study was undertaken once a week in a month (May 2022) between 9 a.m. and 1 p.m. (GMT + 7). Determination of sampling sites based on differences in land use. Sampling site 1 is located at the Kedungkandang Dam, sampling site 2 is located at the Waterfall Amprong tourist area, sampling site 3 is located at the river branch below the Kedungkandang bridge, and sampling site 4 is located in a residential and agricultural area. The total abundance of freshwater periphytic diatom ranges from 938,905 Ind/mm2 - 1,597,758 Ind/mm2. The lowest total abundance is at station 1 with a value of 938,905 Ind/mm2 and consists of 17 genera. The highest total abundance is at station 4 with a value of 1,597,758 Ind/mm2 and consists of 17 genera. In this study, 27 genera were found spread across 3 phylum.

Abstract. Lestari NKD, Deswiniyanti NW, Sari NKY, Murna IM, Rizqy AN. 2023. Morphological relationships and cross compatibility of seven Dendrobium species in Indonesia. Biodiversitas 24: 3550-3558. The development of Dendrobium hybrid orchids in Indonesia has received less attention. This study aimed to obtain the morphological characteristics and taxonomical relationships of Dendrobium species, their interspecific and intersectional compatibility for hybridization, as well as the fertility of hybridized Dendrobium orchids. Seven Dendrobium species from several sections were used, namely D. phalaenopsis, D. lineale, D. stratiotes, D. macrophyllum, D. nobile, D. heterocarpum and D. bracteosum. We characterized the seven species based on morphological traits and investigated the taxonomical relationships using hierarchical cluster analysis by dendrogram charts. We then crossed the seven species to produce hybrids and the hybrids were then cultured in vitro. The hybridization and in vitro culture data were analyzed using an ANOVA test with Duncan's post hoc test when the results significantly differed. The results showed that the taxonomical relationship was clustered based on the sections of each Dendrobium species. The highest percentage of hybridization compatibility was found in D. phalaenopsis and D. lineale with 61.9% while the lowest was in D. nobile, and D. bracteosum (0%). Germination percentages in in vitro culture ranged from 40% to 100% for both interspecific and intersectional crosses, except for intersectional crosses of D. nobile, which failed to germinate. The findings of this study suggest that the results of interspecies and intersectional crossing showed that the highest compatibility was indicated by D. phalaenopsis and D. lineale. Therefore, they are highly recommended as the parents of hybrid orchids.

Authors: Sulistyowati Ayu , Jati Ariya
Published: July 2023

This article concerns with loneliness. Loneliness is an unpleasant condition, and the writers are interested in the condition expressed in James Arthur’s “Empty Space”. The aim of the writing of this article is to describe the loneliness as depicted in the song lyric. The writers focus on the cause of loneliness experienced by the “I”, and the type of loneliness experienced by the “I”. The writers use library research to collect data, and they apply a textual analysis to figure out the theme and symbol. The writers adopt the concept of loneliness of Daniel Perlman and Letitia Anne Peplau. The discussion indicates that the cause of the loneliness experienced by “I” is the feeling of emptiness when he had lost his lover. Thus, the emergence of this feeling of loneliness is included in the type of emotional loneliness.

Published: July 2023

The effect of hydrogen bonding on the structure and vibrational spectra of 2-benzylphenol has been studied. IR spectra were measured in the range 400 – 4000 cm-1 in the temperature range 11 – 335 K in stable and metastable phases solid-crystalline and liquid. Structural-dynamic models of the most stable in crystalline phase conformer of the 2-benzylphenol molecule and its H-complexes: a chain associate fragment and a cyclic tetramer, were constructed using the B3LYP/6-31g(d) density functional theory method. The parameters of adiabatic potentials are calculated: minimum energy, optimal geometry, force constants, dipole moment. Frequencies and forms of normal oscillations and their intensity in IR spectra are calculated. Based on the analysis of the results of modeling and measurements, conclusions were made about the structure of 2-benzylphenol samples and an interpretation of its IR spectra was given.

Micro-magnetic technology has a small size and high spatial resolution,
efficiently realizing the targeted stimulation of deep nuclei inside the
brain. Studying the precise magnetic stimulation of the hippocampal
trisynaptic nerve loop in the brain is essential. Within this work we
designed a 1×4-array micro-magnetic stimulation (μMS) device with four
submillimeter sized commercial inductance. A 3 cm circular coil was
utilized to determine that the 70 kHz/2 mT/1 min stimulation parameters
could elevate the LTP within the CA1 region. Then, using a
micromanipulator, the μMS device was shifted to the CA1, CA3, and DG
areas, after successful induction of LTP using HFS with a 1-s train of
pulses delivered at 100 Hz, the fEPSPs was continuously recorded for 15
min. Based on this procedure, two magnetic stimulation schemes were
utilized. Scheme a (magnetic stimulation of a single region). The 70
kHz/2 mT/1 min magnetic stimulation was introduced to CA1/CA3 and DG
target regions. The experimental results revealed that the LTP enhanced
the most in a single CA1 area, followed by the CA3 area, and not
significantly within the DG area. Scheme b (magnetic stimulation of the
multiple regions). First, the CA1 region was magnetically stimulated and
fEPSPs were recorded. Then, further magnetic stimulation of various
areas was performed. Experimental results revealed that the increased
LTP in the CA1 region was the most effective after magnetic stimulation
among the three CA1/CA3/DG regions. Magnetic stimulation of multiple
areas performed better than stimulation of a single region.

Published: July 2023

Представлены результаты трёхлетних (2019 – 2021 гг.) двухфакторных полевых опытов по изучению зависимости урожайности сортов нута Приво 1 и Волгоградский 10 от приёмов основной обработки почвы и применения стимуляторов роста Циркон и Полидон бобовый на чернозёмах обыкновенных Нижнего Поволжья. Применяли 3 способа обработки почвы: вспашка; глубокая чизельная; мелкая дисковая. Установлено, что наименьшая фактическая урожайность нута в среднем 1,53 т/га формировалась у сорта Приво 1 в варианте мелкой дисковой обработки без применения биопрепаратов; наибольшая — 2,68 т/га — в варианте глубокой чизельной обработки с применением биопрепарата Полидон бобовый. Наибольшую урожайность нута обеспечил сорт Волгоградский 10 также в варианте глубокой чизельной обработки с применением биопрепарата Полидон бобовый — 3,02 т/га.
La Star de soccer, figure de « la diversité » au Canada
Authors: Sirois-Moumni Bachir , St-Louis Jean-Charles
Published: July 2023

Dans cet article, nous soutenons que les Stars du soccer au Canada et au Québec, telles que Alphonso Davies et Patrice Bernier, sont des exemples de la « production de la diversité » dans le paysage culturel sportif et médiatique canadien. Davies et Bernier y représentent des formes culturelles qui intègre dans une intrication complexe le sport spectacle, sa marchandisation et la création de mythes collectifs. Dans un système sportif longtemps dominé par le hockey, ils représentent tous deux des points nodaux dans les luttes incessantes autour de la (re)définition de la citoyenneté et de l’appartenance. En explorant notamment leur mise en récit paradoxale comme « immigrants idéaux » au prisme de leur racisation, cet article contribue à éclairer les dynamiques culturelles propres de l’environnement du sport et des médias dans les contextes canadien et québécois. Notre analyse vise ainsi à montrer comment les récits mobilisés pour raconter les trajectoires de Davies et Bernier au sein du complexe culturel média/sport canadien participent de la gouvernementalité propre aux régimes inspirés du multiculturalisme et de l’interculturalisme, reproduisant les inégalités et la discrimination à même un discours qui se veut ouvert et bienveillant.

La piña es el segundo cultivo perenne tropical con más importancia a nivel mundial después del banano, aportando más del 20% del volumen total mundial de frutos tropicales. La calidad de la piña panameña es del deleite nacional y de mercados internacionales como Europa y Estados Unidos, siendo La Chorrera el mayor productor de piña del país. El objetivo de este estudio es realizar un muestreo geoquímico aplicado a labores agrícolas, con el fin de generar mapas geoquímicos de pH y conductividad eléctrica que sean de utilidad a la producción de piña de la finca en estudio. El muestreo se realizó con una malla irregular de 13 puntos de muestras de suelo, y 2 muestras de sedimentos de los cuerpos de agua cercanos. Se tomaron muestras de suelo a 15 cm de profundidad, y se midió el pH y conductividad eléctrica. En todo el perímetro de la finca los valores de pH del suelo fueron ácidos, siendo el mínimo 4.25 y el máximo 5.09. Se observó que las zonas con mayor conductividad eléctrica fueron los sedimentos de los cuerpos de agua, mientras que las zonas de producción agrícola estuvieron en un rango de 21 a 107 µS/cm. Concluyendo así que la zona se ve afectada por fenómenos como la erosión y el transporte de sedimentos hacia los cuerpos de agua, lo cual guarda relación directa con el relieve de la zona de estudio, y podría indicar también como se realiza el arrastre de los nutrientes aplicados al cultivo de piña.

Published: July 2023

Siltara is the industrial area located some about 15 km away from the Raipur city on Raipur-Bilaspur Road located at about 21022 N and 81039 E.
There are two industrial sites in Siltata, one on the left and another on the right side of the road, named as: Siltara I and Siltara II. Almost all types of
industries, from small to relatively large are located within the area. Plastics have been widely used as a packing material in the form of low density
polyethylene (LDPE). Continuous accumulation of plastic in the environment can cause threat to humanity and environment. In order to stop the
accumulation of plastic and to make the surroundings free from plastic, fugues are isolated from Bhilai, Chhattisgarh area soil. These fugues are
screened by clear zone technique using polythene powder to conrm the degradation activity. Biodegradation of polymer granules by the isolated
organisms and it makes physical and structural changes over a period of time after fungus adhesion to the granules. To check the efciency of
biodegradation, weight method was performed under laboratory conditions for 2, 4 and 6 months. Experimental data revealed that Fusarium
oxysporum sps have highest plastic degradation capacity and it degrades up to 48.9%, this degradation was followed by the Aspergillus niger
(28.27%), and Rhizopus stolonifer (23.10%) for the period of 6 months. This work revealed that Fusarium oxysporum plays a vital role in
degrading polythene powder and polymer granules

Published: July 2023

Introducción: La tuberculosis laríngea es una entidad sumamente rara en países del primer mundo, sin embargo, en nuestro medio no es extraño, como país latinoa­mericano, sospechar esta patología como una de las causas de disfonía y lesiones granulomatosas en la actualidad. La tuberculosis laríngea debe considerarse dentro de las patologías en pacientes con disfonía de larga evolución que no responden al tratamiento común, esta entidad puede ser confundida con neoplasias. Reporte de caso: Se presenta el caso de una mujer en la cuarta década de la vida con disfonía crónica de 6 meses de evolución, que fue remitida para laringoscopia. Se localizaron neoformaciones granulomatosas acompañadas de edema en ambas cuerdas vocales, sometidas a biopsia, con resultados con la tinción de hematoxilina-eosina de células gigantes multinucleadas de Langhans y la tinción Zielh-Nielsen fue positiva para bacilo alcohol ácido resistente. La radiografía de tórax mostró lesiones reticulono­ dulares sugestivas de tuberculosis pulmonar. Conclusión: Un alto nivel de sospecha y un diagnóstico temprano pueden limitar las complicaciones y facilitar un manejo oportuno de estos casos. Es necesario sospechar de tuberculosis laríngea en pacien­tes que presentan disfonía crónica, especialmente cuando se asocia con síntomas constitucionales, aunque no siempre los presentan, por otro lado, en algunos casos, no existe asociación con inmunodeficiencia
Optimal harvesting strategy of a stochastic $ n $-species marine food chain model driven by Lévy noises
Authors: Tuerxun Nafeisha , Teng Zhidong
Published: July 2023

A stochastic $ n $-species marine food chain model with harvesting and Lévy noises is proposed. First, the criterion on the asymptotic stability in distribution is established. Second, the criterion on the existence of optimal harvesting strategy (OHS) and the maximum of expectation of sustainable yield (MESY) are derived. Furthermore, the numerical simulations are presented to verify the theoretical results. Our results show that (i) noises intensity can easily affect the dynamics of marine populations, leading to the imbalances of marine ecology, (ii) the establishment of an optimal harvesting strategy should fully consider the impact of noises intensity for better managing and protecting marine resources.
