En esas trece revistas durante los últimos cinco años (2018-2022), únicamente se han publicado veintiséis artículos de matemática, lo que representa solo un 2,89% de la producción total; este porcentaje incluye artículos que son resultado de alguna investigación y escritos referentes a una revisión bibliográfica.
Characteristics of mental toughness in young basketball players of different age groups
Authors: Pocius Eimantas , Malinauskas Romualdas 
Published: June 2024

PurposeAssessing the development of skills that ensure personal mental toughness in adolescence is important because adolescents’ increasing autonomy and socialisation during adolescence inevitably create the conditions for an increasing number of external stressors to emerge. Paradoxically, adolescents’ confidence in their ability to cope with external stressors decreases during adolescence, which may lead to poorer sports performance in adolescent athletes. This study aimed to determine and analyse mental toughness skills in the cadet and junior age groups of young basketball players. Another aim was to reveal how general (total) mental toughness and age predict each athletic mental toughness skill.MethodsThis study surveyed 378 young basketball players using a two-stage cluster sampling approach. The Mental Toughness Questionnaire 48 (MTQ48) was chosen to assess general mental toughness skills. The Performance Inventory-Alternative (PPI-A) was chosen to assess athletic mental toughness skills.ResultsThe study’s results revealed that players in the junior age group scored significantly higher on challenge (p < 0.001; d = –0.41), commitment (p < 0.001; d = –0.65), emotional control (p < 0.001; d = –0.76), life control (p = 0.02; d = –0.26), overall control
(p < 0.001; d = –0.64), self-confidence in one’s abilities (p < 0.001; d = –0.73), self-confidence in interpersonal interactions (p < 0.001; d = –0.50), overall self-confidence
(p < 0.001; d = –0.73), total mental toughness (MTQ-48) (p < 0.001; d = –0.78), determination (p < 0.001; d = –0.47) and visualisation (p < 0.001; d = –0.81). Significant correlations (r ranges from 0.12 to 0.37) were found between mental toughness skills and age groups for all scales mentioned above, except positive cognition and self-belief. Total mental toughness strongly predicted athletic mental toughness skills, but age did not predict determination and self-belief skills.ConclusionsThe findings of the present study suggest that promoting mental toughness can lead to improved athletic mental toughness indicators, emphasising its relevance for coaches, trainers, and sports psychologists in enhancing athletes’ development and performance.

PurposeThe IRONMAN® triathlon is an endurance multisport discipline of high popularity. Professional IRONMAN® triathletes need to qualify for the IRONMAN® World Championships and, therefore, would benefit from identifying the fastest race courses. Our purpose was to identify the fastest races held for professional IRONMAN® triathletes competing from 2002 to 2022.MethodsThis was an observational study, sampling 7,078 race records (380 different events in 55 different event locations) of professional IRONMAN® triathletes of both sexes (4,235 males and 2,843 females). We downloaded information about sex, nationality, both split (swimming, cycling, and running) and overall race times, the event location, and the year. Information about race course characteristics, water temperatures, and air temperatures was obtained. Descriptive statistics were calculated for each event location, and factorial ANOVA tests were used to explore the statistical significance of the results. A confidence interval of 95% was adopted.ResultsThe fastest overall IRONMAN® average race times were achieved during the IRONMAN® Tallinn, IRONMAN® Switzerland held in Thun, and IRONMAN® Des Moines. A lake for the swim split characterized the first five courses, while the bike split featured rolling or hilly terrain. For the run split, most of the courses were characterized as flat. For environmental characteristics, lower water and air temperatures also added time to the average finish time.ConclusionsUnderstanding the fastest race courses and their characteristics would assist professional IRONMAN® triathletes in selecting races that offer the optimal conditions for their competition. Fast IRONMAN® race courses typically feature a lakeside swim course, a rolling or hilly bike course, and a flat run course.

Objective: To compare maternal bleeding in pregnant women undergoing term and pre-term Cesarean delivery.
Study Design: Comparative cross-sectional study.
Place and Duration of Study: Gynecology and Obstetrics Department, Pak Emirates Military Hospital, Rawalpindi, Pakistan Jan to Jun 2021.
Methodology: A total of 211 pregnant women undergoing Caesarian section at our tertiary care center were included in the study. They were divided into two groups based on gestational age as term or pre-term, with delivery at 37 completed weeks being labelled full term. Lower segment cesarean section was carried out by consultant gynecologist on all the patients as per standard protocol and blood loss was compared in term and pre-term Caesarian deliveries.
Results: Out of 211 study participants, 108(51.1%) had a Caesarian section at term while 103(48.9%) had pre-term Caesarian section. The mean age of participants was 29.35±4.10 years. Mean blood loss during the Caesarian section in term pregnancies was 437.03±129.76 ml while in pre-term pregnancies was 641.26±157.40 ml. Independent t-test showed that bleeding was statistically significantly more in pre-term pregnancies (p-value<0.001). Post-operative hemoglobin was also significantly different in term and preterm pregnancies (p-vale<0.001).
Conclusion: Women undergoing Caesarian section pre-term were at risk of having more blood loss and fall in hemoglobin levels as compared to those undergoing Caesarian section at term.

Authors: Смоленцев А.С. , Веселова В.Е. 
Published: June 2024

Исследовано влияние локального высокоскоростного интенсивного динамического воздействия металлическим предметом (индентором) на изменение структуры металла шва высокопрочной легированной стали, сваренной аустенитной порошковой проволокой с азотом. Установлено, что после сварки структура металла шва состоит из аустенита и дельта-феррита (3 об. %) с микротвердостью HV0,1 200–250. После интенсивного динамического воздействия происходит упрочнение металла шва по механизму γ→ε→α’ за счет наклепа и образования в структуре α’-мартенсита деформации в количестве 10 об. % и незначительного количества ε-мартенсита с сохранением исходного количества δ-феррита, с повышением микротвердости более чем в 1,7 раза от первоначального уровня.
The effect of local high-speed intense dynamic action by a metal object (indenter) on the change in the structure of the weld metal of highstrength alloy steel welded with nitrogen austenitic flux-cored wire has been studied. It is established that after welding the structure of the weld metal consists of austenite and delta-ferrite (3 vol. %) with microhardness HV0,1 200–250. After intense dynamic action, the weld metal is strengthened by the mechanism γ→ε→α’ due to work hardening and the formation of deformation in the structure of α’-martensite in the amount of 10 vol. 5 and a small amount of ε-martensite while maintaining the original amount of δ-ferrite, with an increase in microhardness by more than 1.7 times from the initial level.

Краткая эколого-морфологическая характеристика Scolochloa festucacea (Willd.) Link (Poaceae) в северной части Европейской России
Authors: Бобров Юрий Александрович , Филиппов Дмитрий Андреевич 
Published: June 2024

На основе собственных полевых исследований и анализа гербарных коллекций дана эколого-морфологическая характеристика крупного слабоизученного растения – Scolochloa festucacea (Willd.) Link (семейство Poaceae). На территории Европейского Севера России тростянка овсяницевидная растёт по берегам водораздельных и пойменных озёр, медленно текущих рек и их заводей, реже – на влажных и заболоченных лугах и приозёрных болотах. Для вида, согласно экологическим шкалам Д.Н. Цыганова, лимитирующими факторами макроклимата следует, по-видимому, считать баланс осадков и испарения и общую температуру, микроклимата – освещённость и богатство почвы минеральными солями. Экотопы в изученных сообществах с участием S. festucacea, находятся в условиях слабопеременного увлажнения, имеют влажность субстрата, колеблющуюся от сыро- до болотно-лесолуговой, незасолённые, бедные азотом, но довольно богатые минеральными солями с pH 4,5–6,5 почвы, с освещённостью, соответствующей полуоткрытым пространствам. Жизненная форма вида S. festucacea определена как подземностолонный недерновый травянистый многолетний поликарпик. Основу целостного растения образуют монокарпические побеги, после отмирания которых резид входит в состав сложного столона. Подземная часть растения содержит много почек, которые могут тронуться в рост при повреждении верхушки. Это позволяет растению быстро восстанавливать потерянную биомассу.

The Greekness of the generation of the ʼ30s and the case of Thrassos Kastanakis
Authors: Θεολόγου Β. 
Published: June 2024

Οι έννοιες της ελληνικότητας και του εθνισμού στη λογοτεχνία είναι άμεσα συνδεδεμένες με τη γενιά του 1930 και την περίοδο του μεσοπολέμου και εμπεριέχουν ουσιαστικά το γνωστό θέμα του δυϊσμού της εθνικής ταυτότητας αναφορικά με το παρελθόν και με τη Δύση. Εστιάζοντας λοιπόν στην έννοια της ελληνικότητας, στόχος τoυ προτεινόμενου άρθρου είναι να διερευνηθεί ο τρόπος με τον οποίο ο Θράσος Καστανάκης αποδίδει τα χαρακτηριστικά και την ιδιοσυγκρασία του Έλληνα, τη συμπεριφορά και τη νοοτροπία του μέσα και έξω από την πατρίδα, εξετάζοντας όμως ταυτόχρονα και την επιρροή που έχει το δυτικό περιβάλλον, καθώς και ο δυτικός τρόπος ζωής στη διαμόρφωση του χαρακτήρα και της προσωπικότητάς του.
The concepts of Greekness and nationism in literature are directly linked to the generation of the 1930s and the interwar period and essentially contain the well-known theme of the dualism of national identity in relation to the past and the West. Focusing therefore on the concept of Greekness, the aim of the proposed article is to investigate the way in which Thrassos Kastanakis depicts the characteristics and temperament of the Greek, his behaviour and his mentality inside and outside the homeland, while at the same time examining the influence of the Western environment and the Western way of life in shaping his character and personality.

Το παρόν άρθρο έχει ως θέμα του τη βυζαντινή-εκκλησιαστική μουσική της ελληνορθόδοξης εκκλησίας, όπως αυτή παρουσιάζεται σε κείμενα τριών σπουδαίων Ελλήνων λογοτεχνών του 19ου και του 20ού αιώνα, του Αλ. Παπαδιαμάντη, του Στρ. Μυριβήλη και του Φ. Κόντογλου. Συγκεκριμένα, τα ζητήματα τα οποία θίγονται στο άρθρο είναι δύο: αναδεικνύονται, από τη μια, τα βασικά χαρακτηριστικά γνωρίσματα της μουσικής αυτής, τα οποία συνιστούν, σύμφωνα με τους τρεις προαναφερθέντες συγγραφείς, τα προτερήματά της, ενώ, από την άλλη, γίνεται απόπειρα να σκιαγραφηθεί το πορτρέτο των επικριτών της, με την παράλληλη καταγραφή και των αιτιάσεων που διατυπώθηκαν από αυτούς σε βάρος της.
The present paper traces the role of byzantine religious music of the Greek Orthodox Church, as it is present in the works of three very important 19th and 20th century Greek writers, namely Al. Papadiamantis, Str. Myrivilis and F. Kontoglou. In specific, the issues to be traced are mainly two: first we present the basic technical elements of this kind of music, which, according to our writers’ opinions, consist this music’s advantages, and second we will try to offer an outline of the criticisms this kind of music had from certain scholars, mentioning also those certain accusations against it.
Greek wedding folk songs in Claude Charles Fаuriel’s collection “Chants populaires de la Gréce moderne”
Authors: Χριστακούδη-Κωνσταντινίδου Φ. 
Published: June 2024

Τα δημοτικά τραγούδια ανήκουν στην προφορική τέχνη, που σημαίνει ότι δημιουργούνται και αναπαράγονται με κανόνες διαφορετικούς από αυτούς των γραπτών κειμένων. Τεράστια συμβολή στην παρουσίαση του θησαυρού των ελληνικών δημοτικών τραγουδιών στην Ευρώπη τον 19ο αιώνα έχει ο Γάλλος επιστήμονας Κλοντ Σαρλ Φοριέλ (1772–1844) και η συλλογή του από ελληνικά δημοτικά τραγούδια με τίτλο «Ελληνικά δημοτικά τραγούδια από τη σύγχρονη Ελλάδα» («Chants populaires de la Grèce moderne»). Ο ίδιος, αν και ποτέ δεν είχε επισκεφτεί προσωπικά την Ελλάδα, οδηγούμενος από την αγάπη του για το παρελθόν της και το έθνος της, μετέφρασε στα γαλλικά τη συλλογή του με ελληνικά δημοτικά τραγούδια και την εξέδωσε το 1824–1825 σε δύο τόμους. Τα τραγούδια του γάμου της συγκεκριμένης συλλογής αποτελούν ένα πολύτιμο κόσμημα του ελληνικού παραδοσιακού πολιτισμού.
Folk songs belong to oral art, which means they are created and reproduced according to rules different from those of written texts. The French scholar Claude Charles Fauriel (1772–1844) and his collection of Greek folk songs entitled “Greek Folk Songs from Modern Greece” («Chants populaires de la Gréce moderne») made a huge contribution to the presentation of the treasure of Greek folk songs in Europe in the 19th c. Although he had never personally visited Greece, led by his enormous love for her past and nation, Fauriel translated in French his vast collection of Greek folk songs and published them in 1824–1825 in two volumes. The wedding songs in the second volume are a precious jewel of Greek traditional culture.
