Authors: Ramsewak Samuel , Timothy Marlon , R. Gidla Sanju , Brathwaite Earl , Chinnia Javed
Published: June 2024

A 39-year-old, gravida 3 para 0+2 presented at 26+4 weeks gestation with a clear vaginal discharge which upon speculum examination revealed prominent bulging amniotic membranes and a pool of clear amniotic fluid in the vagina. Abdominal ultrasound showed a single viable fetus in longitudinal lie, cephalic presentation and fetal heart rate (FHR) 150 beats per minute, regular. Estimated fetal weight 863g. The past history included 2 previous missed miscarriages. A diagnosis of pre-term premature hind water rupture of membranes was made. Intravenous antibiotics, magnesium sulphate, intramuscular progesterone and antenatal steroids were administered and emergency (double) cervical cerclage was performed after amnioreduction. The next day, the patient showed features of frank rupture of membranes and severe oligohydramnios on ultrasound. Six weeks after cerclage (32+4) considering the persistent amniotic fluid leakage with severe oligohydramnios, planned Caesarean section delivery was performed and a male fetus, weighing 1790 grams was delivered with APGAR scores of 7 and 8 at 1 and 5 minutes respectively. NICU care included invasive volume targeted ventilation, double dose surfactant administration and management of neonatal sepsis with β-haemolytic streptococci. Echocardiographic assessment was normal and feeds were initiated after 3 days of oral immune therapy using colostrum. After 14 days of NICU stay, the neonate was discharged.

Authors: Chandramouli Roshni , Rajan Niranjana , Veerappan Venkatachalam , Venkatesan Dhanalakshmi , Balasundaram Patheeban
Published: June 2024

Xanthogranulomatous endometritis is a pathological entity which has an unusual characteristic of partial or complete replacement of the mucosa by granulation tissue with plenty of foamy histiocytes, sidero blasts and multinucleated giant cells. This condition clinically and radiologically mimics an endometrial carcinoma, which might create panic in patients as well as healthcare professionals. Hence it is important for Gynaecologists and pathologists to be aware of this condition so as to differentiate it from malignancy. Coexisting malignancy too is a possibility to be ruled out. We report case of a 69-year-old for whom we had high suspicion for malignancy based on clinical and radiological features, hence surgical oncologist opinion was obtained and total laparoscopic hysterectomy+bilateralsalpingo-oophorectomy and frozen section was performed-reported as inflammatory reaction. Hence, further oncological procedure (lymphadenectomy and omentectomy) was abandoned. The final Histopathology was reported as xanthogranulomatous endometritis. We are publishing this case report due to rarity(<30 cases reported worldwide) and its close resemblance to malignancy clinically and radiologically.
Research Insights: Can Dynamic Targeting Mechanisms Improve the Social Value of Safety Nets?
Authors: Vera Diego , Hoffmann Bridget , Vargas David , Stampini Marco
Published: June 2024

Traditional proxy-means tests approaches to selecting beneficiaries of social programs can exhibit higher levels of exclusion errors when income fluctuates. These errors can erode the social value of a safety net. Expanding the coverage of the safety net reduces exclusion errors but entails either larger budgets or substantial reduction of benefits. A dynamic targeting approach that includes updated information on labor market and other shocks can reduce targeting errors and increase the social value of the safety net at a substantially lower cost, relative to an expansion of the safety net.
O znaczeniu i roli kontemplacji i medytacji w filozofii
Authors: Krokos Jan
Published: June 2024

Celem niniejszego artykułu jest rozważenie znaczenia i roli kontemplacji i medytacji w filozofii. Filozofia jest tu rozumiana klasycznie — jako umiłowanie mądrości, jako rodzaj myślenia teoretycznego, podejmującego najbardziej ogólne zagadnienia, dotyczące świata. W spełnianiu tego zadania doniosłą rolę odgrywają kontemplacja i medytacja. Kontemplacja jest stanięciem w obliczu bytu czy przedmiotu i intelektualnym chłonięciem go przez podmiot poznający. Jest nieuprzedzonym oglądaniem czegoś czy przypatrywaniem się czemuś, co jest jakoś transcendentne wobec podmiotu kontemplującego. Natomiast medytacja jest namysłem nad życiem świadomościowym podmiotu. W poznaniu filozoficznym dopełniają się. Kontemplacja gwarantuje obiektywność poznania, a medytacja — czuwanie nad prawidłowością aktów poznawczych.
O uniwersaliach i Bogu — głos w dyskusji
Authors: Rosiak Marek

Tekst, nawiązujący do artykułu Stanisława Judyckiego „Bóg i uniwersalia”, zawiera analizę zasadniczych stanowisk w sporze o uniwersalia i przedstawia własną interpretację niektórych kluczowych kwestii tej problematyki — zwłaszcza koncepcji tak zwanego realizmu umiarkowanego, przypisywanego Arystotelesowi. Wspomniana jest też ewentualność wykorzystania tego rodzaju rozważań w innym zagadnieniu klasycznej metafizyki — w kwestii istnienia Absolutu.
Wszechsubiektywność jako atrybut Boga
Authors: Zagzebski Linda Trinkaus , Iwanicki Marcin , Teske Klara Joanna
Published: June 2024

Autorka argumentuje, że istnienie subiektywności wymaga przypisania Bogu dodatkowego atrybutu, który nazywa wszechsubiektywnością. Jest to własność świadomego ujmowania z doskonałą trafnością i w sposób całkowity każdego świadomego stanu każdego świadomego stworzenia z pierwszoosobowej perspektywy tego stworzenia – z perspektywy ja. W obronie możliwości wszechsubiektywności odwołuje się do analogii z empatią. Jak argumentuje, że biorąc pod uwagę istnienie świadomych istot we wszechświecie, wszechsubiektywność wynika z takich tradycyjnych atrybutów, jak wszechwiedza i wszechobecność, i jest implikowana przez tradycyjne praktyki modlitewne. Na koniec, wykorzystując ideę ujmowania przez jedną osobę subiektywności drugiej, Autorka podaje pewne wyjaśnienie różnic między świadomościami Osób Trójcy Świętej.

Na tropach wieczności
Authors: Kawalec Anna , Kawalec Paweł
Published: June 2024

Artykuł naświetla rzadko komentowane tematy w odniesieniu do prac Stanisława Judyckiego, zwracając szczególnie uwagę na problem znaków wieczności w doświadczeniu doczesnym. Dla pełniejszego ich wydobycia przywołuje nieoczywiste konteksty spoza kultury zachodniej, które jednak istotnie wpisują się w cały dorobek intelektualny Stanisława Judyckiego. Oprócz sformułowania problemu, szczególnej oryginalności upatrujemy w przezwyciężeniu przez niego rzekomo konstytutywnej więzi filozofii podmiotu z ideą postępu. Efektem są unikatowe wglądy w sytuację egzystencjalną człowieka w jego relacji do Boga.

Authors: Guamán Roldán Hugo Xavier , Cabrera Abad Daniela Paola , Quelal Chuisaca Kevin Lenin
Published: June 2024

Las fístulas oro-nasales son secuelas muy comunes luego de una cirugía de reconstrucción de paladar en pacientes con antecedentes de paladar hendido, y muchas de ellas pudiendo causar sintomatología a las personas que la padecen. El colgajo lingual de base anterior ha demostrado ser una alternativa quirúrgica ideal al demostrar altas tasas de éxito en los pacientes. La reconstrucción busca sustituir el tejido con técnicas simples idealmente en etapas tempranas para evitar alteraciones en el crecimiento facial y problemas de fonación. La elección del procedimiento quirúrgico depende del tamaño y ubicación de la fístula, así como del tejido disponible. En este sentido, se emplean diversos enfoques quirúrgicos, siendo el colgajo lingual la preferencia en casos complejos debido a su menor incidencia de complicaciones y los buenos resultados estéticos que ofrece. Objetivo: Presentar un caso clínico sobre la corrección quirúrgica de una fístula oro-nasal en un paciente de 16 años de edad mediante un colgajo lingual de base anterior.
Animalist art as a model for an ecocentric and postanthropocentric pedagogy
Authors: Gutiérrez-Jordano Carmen
Published: June 2024

In contrast to the anthropocentrism that has dominated Western education, the aim of this work is to present the pedagogical power of animalist art in ecocentric and postanthropocentric education, especially for the care of the otherness of nature and animals. The justification of the theme lies in the need for a change of mentality in light of the dangers threatening nature. The methodology used in this work includes, on the one hand, the analysis of the concepts of care, otherness and their educational value, and, on the other hand, the intuition through the examples of animalist art itself. The conclusions are threefold. First, care is especially concerned with those who have no voice, such as nature and animals. Second, it is necessary to educate to promote the care of nature and animals. Third, animalist art is a foundation for ecocentric education.

Authors: Špindler Tomi
Published: June 2024

S toplejšimi in krajšimi zimskimi sezonami ter taljenjem ledenikov se povečuje potreba po umetnem snegu, kar predstavlja izziv za smučarsko industrijo, ključno za turizem. Smučišča so tako postavljena pred potrebo po trajnostnih politikah, ki bi zmanjšale njihov ogljični odtis. V Sloveniji, kjer so infrastrukturne povezave in smučarska infrastruktura pomanjkljive, strategija turizma za obdobje 20222028 predvideva preoblikovanje smučišč v celoletna turistična središča. To vključuje naložbe v infrastrukturo ob upoštevanju vpliva na podnebne spremembe. Zmanjšanje emisij v zimskem turizmu zahteva sistematične rešitve tako na mednarodni kot na lokalni ravni. Spodbujanje prehoda na okolju prijazen prevoz, kot sta železniški ali avtobusni prevoz, ter vključevanje učinkovitih sistemov upravljanja z energijo na smučiščih so ključni koraki. To zajema spremljanje energetske učinkovitosti in uporabo obnovljivih virov energije ter boljšo optimizacijo procesov, kot je zasneževanje. Pri tem je pomembno tudi upoštevati potencialne ekološke vplive in izbiro trajnostnih alternativ. Celovit pristop k trajnostnemu razvoju zimskih športov vključuje naložbe v trajnostno infrastrukturo, spodbujanje okolju prijaznih oblik prevoza, učinkovito rabo energije na smučiščih ter ozaveščanje in aktivno sodelovanje posameznikov pri zmanjšanju ogljičnega odtisa.

Published: June 2024

Relevance. The need to create new safe energy sources that can meet the needs of production and medicine where the use of traditional energy sources is impossible or unprofitable. Such sources may include radioisotope power sources, in which energy production is ensured by the natural decay of radionuclides. The most important components of current sources such as supercapacitors are electrode materials, the characteristics of which determine the electrophysical characteristics of radioisotope sources. This work proposes a method for synthesizing a carbon matrix doped with Sr for use as electrodes of radioisotope power sources. Aim. Development, mastery and optimization of a method for synthesizing electrodes of radioisotope power sources based on carbon materials doped with the Sr-90 radioisotope. Objects. Carbon material doped with a radioisotope simulant Sr-90 (Sr stable). Carbon matrices were obtained by carbonizing a resorcinol-formaldehyde resin doped with a stable strontium salt. Methods. Scanning electron microscopy, low-temperature adsorption-desorption of nitrogen, cyclic voltammetry, galvanostatic charge-discharge, impedance microscopy. Results. A carbon matrix doped with a stable strontium isotope was synthesized by the method of semi-carbonization followed by physical activation with carbon dioxide. The structure, porosity and electrochemical characteristics of the material were studied. It was established that physical activation has a positive effect on the development of the specific surface area and mesoporosity of the samples of the synthesized matrix, as a result of which its electrochemical characteristics are improved. The method of physical activation is proposed as the most preferable for the synthesis of a carbon matrix doped with strontium isotopes for use as electrodes of radioisotope power supplies.

Authors: Andreeva Elizaveta S. , Marinina Oksana A. , Turovskaya Lyudmila G.
Published: June 2024

Relevance. The fact that with the help of modern methods of increasing oil recovery, it is possible to extract no more than 34 % of oil from the initial recoverable reserves. Therefore, modernization of technologies for tertiary impact on the reservoir as one of the possible ways of developing this area is required. It is possible to use nanoparticles in order to increase the oil recovery coefficient by displacing residual and hard-to-recover oil. Technologies with the use of nanoparticles have a number of significant advantages over the already traditional polymer, alkaline and surfactant flooding. Nanofluidic flooding allows increasing the oil recovery coefficient. The paper considers the mechanisms of action of nanoparticles contributing to oil recovery, the relationship of the effectiveness of flooding from the reservoir temperature, pH, water mineralization and wettability of the reservoir rock surface. These mechanisms are required for identifying limitations of the applicability of nanofluids, the possibility of their modification, in order to improve the properties and eliminate the disadvantages of nanofluid flooding. The effect of the chemical nature of nanoparticles, their size, surface charge, isoelectric point and concentration on rock, reservoir fluids and the efficiency of hydrocarbon extraction is considered in detail. Attention is also focused on the latest modern trends in the development of nanofluidic flooding technology. Aim. To conduct a comprehensive analysis of nanofluidic flooding as a method of increasing oil recovery. Objects. Chemical methods of enhancing oil recovery, nanofluidic flooding. Methods. Analysis of current publications on the research topic. Results. The factors influencing the effectiveness of the use of nanofluids as a method of increasing oil recovery and the mechanisms of the impact of nanoparticles on oil reservoirs are formed, promising directions for the development of nanoparticle technology are identified.

Authors: Grechushnikov Vladislav V. , Shilin Alexander A. , Prohorov Sergey V.
Published: June 2024

Relevance. Lumber drying is associated with high risks of obtaining a low-quality or even unusable product. The problem under consideration has a number of reasons, both in violation of the technological process and in incorrect settings of drying mode parameters at different stages. The procedure for automated adjustment of parameters is usually associated with a linguistic assessment of the quality of the product, according to which a decision on adjusting the parameters should be made, taking into account signs of a violation of the technological process. Technical and scientific publications contain generalized information about methods for selecting parameters for various situations, which can be formalized and included in algorithms for adjusting the parameters of a programmable logic controller. Aim. To create an algorithm using a Fuzzy controller that allows you to configure process parameters and adapt the drying chamber to the optimal parameters for drying lumber under given operating conditions. Methods. Analysis of the technical process database obtained during one and a half years of operation of the main parameters dispatch system for 28 full lumber drying cycles, with the aim of forming an automated adjustment algorithm that takes into account the lumber drying conditions. Results. The authors have created an algorithm for automated adjustment of parameters for three stages of drying based on linguistic ideas about the quality of the product. The algorithm eliminates the possibility of obtaining a low-quality product, as well as encourages service personnel to correctly generate a technological process passport. Conclusions. The inclusion of an automated parameter adjustment loop in the control circuit allows us to minimize the number of poor-quality processes when starting to operate a new drying chamber and eliminate defects in further technical processes.

Published: June 2024

Relevance. Provisions on the need to transition to alternative energy sources and energy security, reduction of environmental emissions and energy conservation in various industries can largely rely on the use of geothermal energy. A separate area in the field of modeling geothermal technologies is the study of thermal regimes of geothermal heat exchangers. The need to ensure reliable thermal contact between the geothermal heat exchanger and its environment leads to the use of a variety of backfills, including pre-moistened ones. Aim. Study of the intensification of heat supply to geothermal heat exchangers, taking into account the influence of moisture evaporation in its backfill, its characteristics and operating conditions of the systems under consideration. Methods. The solution to the problem was obtained by the finite difference method. An implicit difference scheme and sweep algorithm were used. The coordinate step ranged from 1 to 10 mm. Results and conclusions. Study was carried out for six months of continuous operation of a geothermal heat exchanger. When analyzing the thermal conditions of the system under consideration, the main attention was paid to the study of the intensification of heat supply to the geothermal heat exchanger, taking into account the influence of moisture evaporation in its backfill, its characteristics and operating conditions of the systems under consideration. It has been established that an increase in the humidity of the sand backfill of a geothermal heat exchanger leads to a growth in heat inflows by 3.2–7.8%. A significant influence of the unsteadiness of transfer processes on the intensification of heat transfer in the system under consideration was revealed. It was shown that the increase in heat flow to the geothermal heat exchanger due to the presence of evaporation is about 22%. The conclusion is substantiated that when choosing an option for regulating the thermal conditions of geothermal heat exchangers, the volumetric humidity of the sand backfill should be primarily changed.

В рамках интенсификации методов кормления в аквакультуре применяются различные кормовые добавки. Введение ультрадисперсных частиц (УДЧ) металлов-микроэлементов в рацион рыбы показывает положительную динамику прироста массы и активацию ферментативных процессов. В настоящей работе представлены результаты исследования нанокомпозита Fe-C на рост и развитие молоди карпа. Применение наноструктурированных углеродных композитов демонстрирует позитивную тенденцию к приросту массы карпа. Скармливание опытным образцам карпа нанокомпозита Fe-C в количестве 0,8 мг/кг корма показало увеличение массы на 13,3% в сравнении с контролем. Увеличение концентрации нанокомпозита до 2 мг/кг характеризовалось снижением темпов прироста по сравнению с I опытной группой. Таким образом, можно сделать вывод о перспективности использования металл-углеродных нанокомпозитов в кормлении рыб.

Published: June 2024

Soccer match play and training have been documented to significantly impair players' physical function and affect their perceptual wellness, indicating the necessity of evaluating the response to mixed-content training across a soccer season (Deely et al., 2022, Front Physiol, 13, 911009; Brownstein et al., 2017, Front Physiol, 8, 831; Thomas et al., 2017, Med Sci Sports Exer, 49, 955-964). This study aimed to assess seasonal variation in physical, perceptual, and cognitive functions in response to training among professional academy soccer players, to identify whether players develop increased physical robustness or encounter greater physiological and psychological impairments due to the demanding training and match schedule. Ethical approval was granted for sixteen academy players (age: 18 ± 1 years) to undergo a range of tests at three seasonal points - early, mid, and late - at baseline, immediately post-strenuous training, and at 24, 48, and 72 h. The testing regime encompassed physical performance (countermovement jump [CMJ], ten-to-five repeated jump test [10/5 RJT]), cognitive function (Stroop task, Four-Choice Reaction Time [FCRT] test, Corsi Block Test), and perceptual responses via an adapted Short Questionnaire of Fatigue (SQF). Linear mixed modelling (LMM) was employed to analyse the impact of season phase and testing time-points on training response, incorporating testing measures as dependent variables. Jump performance varied across time-points, with performance maintained immediately post-training, although displaying decrements at 24 h (P < 0.001), 48 h (P < 0.01), and remained unresolved at 72 h (P < 0.05). Season phase exerted a fixed effect on physical function, with vertical jumps decreasing from both early- (P = 0.033, CMJ; P < 0.001, 10/5 RJT) and mid-season (P < 0.001, CMJ; P < 0.001, 10/5 RJT) to late-season. Perceptual measures—soreness, fatigue, and readiness to train—varied across the week, with immediate post-session impairments recovering by 48 and 72 hours. Cognitive function remained relatively stable across the training week, with only a decline in Corsi Block performance noted immediately post-session. An improvement in FCRT from early to mid-season was observed, though accuracy decreased from early to late-season. No interaction between season phase and training week time-points was found across any variable, indicating a consistent training response throughout the season, despite substantial impairments in physical function and declines in perceptual wellness observed post-training. The decrease in physical function during the late-season phase underscores the need for enhanced recovery focus and training load monitoring as the season progresses.
The Relative Age Effect presents an opportunity for Scottish football to be “better than FC Barcelona”
Authors: Craig Thomas P. , Navarro Javier Fernandez
Published: June 2024

An overrepresentation of athletes born earlier in the year compared with those born later in the year is known as the relative age effect (RAE). A ten year analysis of professional players across ten of the top European leagues showed the existence of an RAE in the ten years from 2000 (29.3 vs 19.8%, p<0.01) to 2010 (31.9 vs 18.4%, p<0.01) with the RAE becoming more pronounced with time. A sample from the FC Barcelona Model (Doncaster et al., 2020. Front Sports Act Liv, 2, 91) showed a strong RAE within their male football academy in all youth groups becoming less prevalent with increasing age (Q1 Jan-Mar = 0.53 Q2 Apr-Jun = 0.27; Q3 Jul-Sep = 0.14; and Q4 Oct – Dec = 0.06 [χ_3^2= 53.6, p<0.001]).  Despite solutions being proposed in the literature, this indicates these solutions are not being utilised effectively within Europe’s top clubs such as FC Barcelona. Our previous work (Craig and Swinton, 2020, Eur J Sports Sci, 21, 1101-1110) identified strong relative age bias in players awarded professional contracts between 2006 and 2016 in a Scottish academy (Q1 = 0.50; Q2 = 0.26; Q3 = 0.20; and Q4 = 0.05 [χ_3^2= 40.9, p<0.001]). Scottish clubs have limited resources in comparison with Barcelona meaning academy efficiency is paramount. The main study aim was therefore to assess any changes in the relative age effect over a ten-year period in an elite Scottish football academy within the academy player pool. A secondary aim was to establish if physical differences exist across each quarter to assess the impact of any potential RAE. Following ethical approval, a retrospective analysis of 512 academy players (from 2006 to 2016) from a Scottish Academy was assessed for anthropometric, physical performance and RAE impact.  The range of players in each quarter was Q1 37.0-42.9% versus Q2 22.8-32.4%, Q3 11.9-26.0% and Q4 7.1-14.3%. Odds Ratio analysis indicate a greater chance of selection within the academy when assessing Q1 vs Q4 players quarter comparisons (ranging 3.2-5.2 time more likely to be part of the academy).  There was no impact of time on the RAE over the ten years (p=0.3127). When controlling for age group multilevel modelling showed there were no significant differences across quarters in physical measures. Underrepresented Q4 players who transition through academy soccer can match physically their older peers. The finding that there is no improvement in the RAE with time underpins an efficiency that can be integrated.  Using established interventions and corrective procedures can ensure no potential is being removed unnecessarily from the development pathway on the basis of RAE, addressing challenges in financially restricted environments such as Scottish football that resource rich environments such as FC Barcelona have not yet overcome.
The effect of the goal kick rule change on the team’s performance in ball possession and goal scoring in elite male football
Authors: Torkornoo Benjamin
Published: June 2024

Goalkeepers have always played an important role Defensively. Due to rule changes and tactical transitions, goalkeepers now also have an influence on attacking aspects of the game (Szwarc et al., 2023, Baltic J Health Phys Act). The most recent rule change allows attacking players in the box during goal kicks, which creates extra space for the attacking team at the time of the goal kick without direct pressure from the opponent. This is beneficial for teams in the build-up who try to increase space to create goal scoring opportunities in advantageous positions eventually high up the pitch (Goes et al., 2019, Big Data, 7, 57-70). This latest rule change gives the attacking team an extra 640 m2 of space to displace the opposition defence in deeper positions to create scoring opportunities. As of date, no research has looked at the goal kick rule change and its effect on the distribution tendencies and tactical approaches implemented, when attempting to progress the ball up the field from a goal kick. This research aims to analyse the distribution tendencies of Premier League teams in the 2022/2023 season and compare goal kick and build-up behaviour between teams, depending on their finishing position in the season. A secondary data analysis will be conducted on Premier League matches during the 2022/2023 season, including 2136 goal kick sequences cropped from 760 games. The location of the first pass of the goal kick, number of passes during the build-up, duration of the build-up phase, and the amount of goalkeeper touches after the initial goal kick will be analysed. Additionally, the outcome of successful goal kicks will be analysed considering the action and location of the action. All data analysis will be done using HUDL Sportscode (v12.29.0., Hudl, USA). Statistical analysis will evaluate the effect of team’s league table position on the start of the goal kick, build up phase, and the outcome of the goal kick.
