Poets as children. On works of the Slovak Trnava group and the Bulgarian ‘Poets of the city’
Authors: Dimova-Gencheva Irena 
Published: November 2024

The aim of the proposed paper is to examine how the poetic text world embodies the idea of a return to the “naïve” perception of the world. The objects of the analysis are two groups of authors – representatives of 20th century Slovak and Bulgarian literature –, which are known in the history of their national literatures as Trnava group and “poets of the city.” The first poetic formation is made up of Ján Ondruš, Ján Stacho, Jozef Mihalkovič, and Ľubomír Feldek, known also as Concretists, the second one consists of Alexander Vutimski, Alexander Gerov, Ivan Peychev, and Valeri Petrov. While the Slovak authors manifested themselves as a poetic group by publishing three manifestos, one of which called We Will Talk about Children’s Literature, the Bulgarian authors were defined as poets of the city post factum by the Bulgarian critics.The selection of these poetry formations is based on typological affinities between the two specific literary phenomena and the similarities in their national political and social contexts during their genesis. Three basic topics can be found in the works of the representatives of both Trnava group and poets of the city – objective imagery, the motif of childhood, and the image of the city. In the present paper, we focus mainly on the use of objective imagery in the process of returning to childhood, which some of the poets’ texts depict. We also look at one of the main themes in their works, which both literary groups inherit from their antecedents in their literatures – everydayness. In this light, the poets of the city are related to the poetry of the Bulgarian writer Atanas Dalchev, while the Slovak authors follow the path chosen by the Czech poetry group Květen and their concept of “poetry of every day.”Through a close reading of selected works of the Slovak Trnava group and the Bulgarian “poets of the city”, we look at the process of engaging the senses in poetry. The main texts chosen for the analysis areA Play for Your Blue Eyes written by Ľubomír Feldek and Tom Thumb by Valeri Petrov. Their poems are based on a return to childhood and sensual concreteness. We examine how the writers stylize the perceived world in opposition to the “ready-made” ideas the socialist realism offers. Both groups of authors choose a new aesthetic formula that roots in portraying the objective world. The topic is represented in light of Maurice Merleau-Ponty’s reflection on the literary use of language.

Published: November 2024

AbstractWe present the case of a 64-year-old man who was incidentally found to have a left atrial mass in the vicinity of the left atrial appendage. Despite adequate anticoagulation for suspected thrombus for 6 months, the appearances of the mass remained unchanged. Surgical resection was recommended to reduce the risk of embolisation and to establish a histopathological diagnosis. Despite our initial suspicions of this being a myxoma the mass was ultimately confirmed to represent a rare papillary fibroelastoma occurring on the endocardial surface of the left atrium. The current report details the multimodality imaging of this phenomenon along with the diagnostic dilemma this unusual left atrial mass initially posed.

Published: November 2024

AbstractBackground and AimThe anatomy and function of different areas within the intraconal fat remain poorly understood. A potential difference between nasal and temporal orbital fat densities in normal eyes may assist clinicians and radiologists in more accurately interpreting computerized tomographic (CT) scans and making more informed diagnostic and therapeutic decisions for patients with orbital pathologies.Patients and MethodsData from randomly selected patients who underwent orbital CT scans at Sheba Medical Center in 2022 were analyzed. Patients with abnormal imaging findings in either orbit were excluded. Intraconal orbital fat density was measured in six nasal and temporal sites by means of Hounsfield units (HU).ResultsThe study included 54 patients (mean age 45.3 ± 25.5 years, 29 [54%] females) who were scanned for ophthalmologic etiologies unrelated to the orbit. Non-contrast-enhanced (NCE)-CT scans were available for 36 patients (67%), CE-CT scans for 31 patients (57%), and both CE and NCE scans for 13 patients. HU values were significantly higher in the nasal orbit compared to the temporal orbit on both NCE-CT (−75.8 ± 7.5 nasal vs. −78.1 ± 8.4 temporal, P < 0.001) and CE-CT (−72.7 ± 6.7 nasal vs. −74.6 ± 8.6 temporal, P = 0.02). Age, sex, and laterality had no effect on the HU values.ConclusionsThe density of nasal intraconal fat is higher compared to temporal intraconal fat, as observed on both CE and NCE-CT scans of normal eyes.These results suggest the presence of anatomical differences between these compartments and could have significant clinical implications in the diagnosis of various orbital pathologies.
Rolnicza przestrzeń produkcyjna i bilans glebowej materii organicznej w województwie podkarpackim
Authors: Buczek Jan 
Published: November 2024

W artykule przedstawiono ocenę potencjału środowiskowego rolniczej przestrzeni produkcyjnej oraz regionalnego zróżnicowania bilansu glebowej materii organicznej w latach 2019-2020, na tle warunków siedliskowych w województwie podkarpackim. Podkarpacie jest regionem o zmiennym potencjale warunków środowiskowych co wpływa na przestrzenne zróżnicowanie poziomu rozwoju rolnictwa i obszarów wiejskich. Największą zmiennością elementów środowiskowych charakteryzujących rolniczą przestrzeń produkcyjną odznaczała się rzeźba terenu. Mniejszą zmienność wykazywała jakość i przydatność rolnicza gleb i agroklimat, a najmniejszą warunki wodne. Bilans glebowej materii organicznej w województwie podkarpackim wykazał, że w 14 powiatach następowała degradacja glebowej materii organicznej w zakresie od -0,01 do -0,38 t∙ha-1 natomiast w pozostałych 7 powiatach stopień reprodukcji materii organicznej wynosił od 0,05 do 1,09 t∙ha-1. Intensyfikacja produkcji roślinnej sprzyjała mineralizacji glebowej substancji organicznej i występowaniu zdecydowanie ujemnego jej bilansu w 4 powiatach zlokalizowanych w środkowo-wschodniej części województwa podkarpackiego, gdzie w celu jego zrównoważenia niezbędne byłoby coroczne przyorywanie słomy w ilości od 1,29 do 1,81t∙ha-1.
Obecnie szerzej postrzega się rolniczą przestrzeń produkcyjną, która oprócz funkcji produkcyjnych pełni również funkcje krajobrazowe i ochronne, jako istotne dla rozwoju obszarów wiejskich. Dlatego też należy tak gospodarować rolniczą przestrzeń produkcyjną aby spowolnić degradację jej czynników środowiskowych.

Background: One of the causes of the decline in the Olive ridley turtle population is the low egg hatching rate due to contamination by pathogenic fungi. Purpose: This study aims to evaluate the results of the isolation and molecular identification of fungal contamination on the eggshells of olive ridley turtles that failed to hatch from three coastal waters in Bali province. Method: Sampling was done using the purposive sampling technique. Samples of failed hatching eggshells from the coast were collected, as many as 2 eggs/semi-natural nest at TCEC. Samples were cultured on PDA media. Macroscopic and molecular identification methods were carried out to determine the species level of fungal isolates. Results: The results showed that 10 fungal isolates were successfully collected. Isolates KL1 and SG1 had white colony surface characteristics, isolates KL4, SY2 and SY3 showed black colonies, and isolates KL2, KL3, SG2, SG3, SY4 had green colonies. Three similar isolates were sent for further molecular identification. The BLASTn results of the nucleotide sequences of isolates SY2 and SG3 showed a similarity to Aspergillus niger strain PHY105 (91%), while fungal isolate KL1 had a similarity to Fusarium solani strain 87, by 98%. Conclusion: This study provides new information about the pathogenic fungi, Fusarium solani strain 87 and Aspergillus niger strain PHY105, which are suspected to be the cause of the hatching failure of olive ridley turtle eggs.

The production of amylase produced by lactic acid bacteria (LAB) has better stability. The purpose of this study was to utilize and determine the characteristics of LAB isolates from porang skin waste which have the potential as probiotics and the activity of amylase enzymes. Isolation was done by fermentation method for 48 h with the addition of starter Pediococcus acidilactici that had been cultured. The results showed that the number of colonies of N1 isolates was 49 ×108 CFU/mL with regular small round colonies, having a convex elevation, the edges of the colonies were round, yellowish white, and Gram positive bacteria because they produced a purple color on Gram staining. Acid resistance test at pH 2.0; 3.0; 4.0; 5.0 and 6.0, the isolates N1 was able to survive at each pH because it showed turbidity in the growth medium. The antimicrobial activity test showed a strong zone of inhibition on S. aureus and S. pyogenes of 10,33 and 11,17 mm and a moderate zone of inhibition on K. pneumoniae, S. dysentriae, and P. aeruginosa, respectively, which was 6,33; 7,7 and 7,5 mm. The positive N1 isolate contained alkaloids as bioactive compounds from the results of phytochemical screening and the results of the FTIR analysis showed that specific groups of alkaloids were N-H, C-N, and C=O at wave numbers 3423.30 cm-1; 1235.45 cm-1; and 1634.81 cm-1.
Protecting arable land, reducing pollution and increasing efficiency: promoting the implementation of crop fallow rotation
Authors: Ye Ma 
Published: November 2024

Abstract

Currently, the quality and quantity of agricultural resources have entered a period of hard constraints, agricultural environmental pollution has become increasingly serious, and the quality of arable land has been declining.In order to promote the sustainable development of agriculture and explore the sustainable use of arable land, this study takes China as an example to analyse the impacts, mechanisms and regulating effects of crop fallow rotation on the ecological efficiency of arable land.Firstly,This study selected the panel data of Chinese provinces and municipalities directly under the central government from 2010 to 2020, and firstly used the non-expectation Super-SBM model to measure the ecological efficiency of arable land in each region of China;Secondly, the effects and differences in effects of crop fallow rotation on the ecological efficiency of arable land were analysed using an asymptotic differences in differences model with two-way fixed effects;Finally, the mechanism of crop fallow rotation and the external influencing factors in the implementation process were explored through regulating analysis and mechanism analysis.The regression results indicate that crop fallow rotation can significantly contribute to the ecological efficiency of arable land, and the results still hold after a series of robustness tests;Differential analyses indicate that crop rotation promotes ecological efficiency of arable land more than crop fallow;The analysis of the regulating effect shows that the small peasant economy reduces the effect of crop fallow rotation, while the government's support to agriculture and the cultivation of new agricultural management subjects can enhance the effect of crop fallow rotation;Mechanism analysis shows that crop fallow rotation can reduce the redundancy level of input factors, reduce agricultural carbon emissions and surface pollution to promote the ecological efficiency of arable land.Based on this, the study makes the following recommendations:1.Strengthen the promotion of crop fallow rotation,implemented with crop rotation as the main focus, with crop fallow as the secondary focus;2.Strengthen the cultivation of new agricultural management subjects, and promote the moderate-scale operation of agriculture;3.Improve the efficiency of the use of arable land, and actively promote agricultural carbon emissions reduction and the treatment of surface source pollution.

Published: November 2024

Abstract

Background
Pulmonary inflammatory myofibroblastic tumor (IMT) accounts for 0.04–0.7% of all lung tumors, and endobronchial IMT accounts for only 10% of all pulmonary IMTs. Little is known about the therapeutic outcomes of rigid bronchoscopy for endobronchial IMT. Here, we report a case series of eight patients with endobronchial IMT underwent rigid bronchoscopy.
Methods
We retrospectively analyzed eight patients with endobronchial IMT between January 2004 and December 2023.
Results
The median age of our patients was 36 years, and 62.5% were male. Dyspnea was the predominant symptom in cases where the tumor was centrally located (n = 6), whereas hemoptysis was the predominant symptom in peripherally located tumors (n = 2). Most cases had high contrast enhancement and a tumor stalk without bronchial wall invasion on computed tomography (CT) and bronchoscopy. Complete endoscopic resection and laser cauterization via rigid bronchoscopy were possible in five patients. There were only two cases in which tumors remained after the procedure, requiring additional treatment (chemotherapy and surgical resection, respectively). In one patient, surgical resection was performed three weeks after the procedure, and the surgical specimen was free of residual tumor. There was no mortality during the median follow-up duration of 18.8 months.
Conclusions
Endoscopic resection and laser cauterization using rigid bronchoscopy appear to be a safe and effective alternative treatment modality to surgery for patients with endobronchial IMT.

Application of EOS based on machine learning method on CFD study of rapid hydrogen refueling process
Authors: Seo Hyo Min , Park Byung Heung 
Published: November 2024

Abstract

Currently, commercially operated hydrogen fuel cell electric vehicles (FECVs) store hydrogen as highly compressed gas form to increase volumetric energy density. To provide a refueling time similar to that of internal combustion engine vehicles (ICEVs), hydrogen refueling stations (HRSs) should supply gaseous hydrogen into FECVs up to high pressure (35 MPa or 70 MPa) in a relatively short time. The refueling process of rapidly filling compressed gas within a confined volume of the storage tank is inevitably accompanied by an increase in temperature. However, the refueling process should be carried out under limited conditions considering the physical safety of the storage tank. Modeling the refueling process under the theoretical basis is useful for understanding the gas filling phenomenon and finding the optimal refueling strategy. In particular, the CFD research method which considers the flow of fluid in a tank offers the local temperature changes inside a storage tank as well as the average temperature. The CFD research is conducted by combining a model representing the fluid properties and a model describing the flow characteristics. Therefore, an appropriate combination of models should be examined before simulating the refueling process of an actual FECVs that requires time and cost that cannot be overlooked. In this study, the hydrogen refueling process is simulated using three equations of state (EOSs) and five turbulent models and, then, the results are compared and quantitively analyzed using experimental data. Experiments of filling type III tank of 74 L up to 35 MPa within 1 min have been chosen to make the assumption of axial symmetry for CFD model valid. Comparing the three EOSs (SRK, PR, ML), it is found that it is possible to improve accuracy and reduce calculation time when using ML EOS which has been developed to describe the behavior of hydrogen. Among the five turbulence models (yPlus, k-ε, realizable k-ε, low Reynolds k-ε, and k-ω) generally used in CFD research, the k-ε and the realizable k-ε model show satisfactory results on the reproduction of mean and local thermal behaviors and calculation time.

Abstract

This study investigated residual levels of carbosulfan and its metabolites in date palm fruit in the UAE using HPLC-MS/MS and QuEChERS method. The method demonstrated excellent linearity (R2 > 0.998), low LOD (0.001–0.04 𝜇g/kg) and LOQ (0.003-0.1 𝜇g/kg), and high recoveries (92%-103%) with low RSD values (1–9%). The matrix effect was negligible (-16.43–17.09%), and uncertainty measurements did not exceed the 50% limit. Carbosulfan was present in all samples, exceeding its MRL in 46% of the samples. Carbofuran and 3-hydroxycarbofuran exceeded their MRL in 4.87% and 40% of the samples, respectively, while 3-ketocarbofuran levels were below the MRL. Dibutylamine was found in 82% of the samples, with an average concentration of 9.01 µg/kg. The health risk assessment for children and adults showed that all HQ values were below the safety limit of 1.0, indicating that date consumption poses no adverse health risks for either adults or children.
Towards a Unified Fold-Cusp Model for Bond Polarity Scaling: Electron Rearrangements in the Pyrolytic Isomerization of Cubane to Cyclooctatetraene
Authors: Ayarde-Henríquez Leandro , Guerra Cristian , Pérez Patricia , Chamorro Eduardo 
Published: November 2024

Abstract

Context
This study meticulously examines the criteria for assigning electron rearrangements along the intrinsic reaction coordinate (IRC) leading to bond formation and breaking processes during the pyrolytic isomerization of cubane (CUB) to 1,3,5,7-cyclooctatetraene (COT) from both thermochemical and bonding perspectives. Notably, no cusp-type function was detected in the initial thermal conversion step of CUB to bicyclo[4.2.0]octa-2,4,7-triene (BOT). Contrary to previous reports, all relevant fluxes of the pairing density must be described in terms of fold unfolding. The transannular ring opening in the second step highlights characteristics indicative of a cusp-type catastrophe, facilitating a direct comparison with fold features. This fact underscores the critical role of density symmetry persistence near topographical events in determining the type of bifurcation. A fold-cusp unified model for scaling the polarity of chemical bonds is proposed, integrating ubiquitous reaction classes such as isomerization, bimolecular nucleophilic substitution, and cycloaddition. The analysis reveals that bond polarity index (BPI) values within the [0, 10− 5]au interval correlate with cusp unfolding, whereas fold spans over a broader [10− 3, ∞) au spectrum. These insights emphasize that the cusp polynomial is suitable for describing chemical processes involving symmetric electron density distributions, particularly those involving homolytic bond cleavages; in contrast, fold characterizes most chemical events.
Methods
Geometry optimization and frequency calculations were conducted using various DFT functionals. In line with recent findings concerning the rigorous application of BET, the characterization of bond formations and scissions via unfoldings was carried out by carefully monitoring the determinant of the Hessian matrix at all potentially degenerate CPs and their relative distance. The computed gas-phase activation enthalpies strongly align with experimental values, stressing the adequacy of the chosen levels of theory in describing the ELF topography along the IRC. The BPI was determined using the methodology proposed by Allen and collaborators.
