In this paper, the method of reference modeling is considered, designed for calculation, analysis and mathematical modeling of nonlinear physical phenomena and technological processes. The advantages of this method, the possibility of its application in the entire range of basic parameters of a nonlinear problem, the uniformity of the design scheme for all types of problems are formulated. The proposed method is used to create models of convective diffusion in an inhomogeneous medium, scattering of thermal electrons in a field with central symmetry, and the behavior of electrical conductivity depending on temperature and dielectric permittivity of wide-band semiconductors. The problem of calculating the transparency of a potential barrier that a particle hits, considered as a test, gave a good result (an error in the range of 0.8-1.2%). In this paper, the main features of using the reference modeling method for solving nonlinear differential equations are demonstrated. The obtained results of analysis and modeling allow us to confidently assess the reliability of the general ideas of the reference modeling method, its design scheme, as well as the convergence of its decompositions, the similarity criteria of the system under study and the selected model. The method proposed in this paper, taking into account its approbation in various conditions, can serve as a basis for application in the study of nonlinear problems of various nature, finding approximate solutions to nonlinear differential equations.

Tyrimo tikslas. Vertinti COVID-19 pandemijos laikotarpiu gimdžiusių moterų potrauminio streso simptomų raišką bei atskleisti jų gimdymo patirtį. Tyrimo metodai. 2021 m. sausio–liepos mėn. atliktas vienmomentinis aprašomasis tyrimas. Į tyrimą buvo kviečiamos gyvą naujagimį pagimdžiusios pilnametės moterys, kurioms po gimdymo buvo praėję 1–12 mėn. Taikyta mišri tiriamųjų imties atranka. Kvietimai dalyvauti apklausoje
 
buvo išplatinti pagimdžiusias moteris vienijančiose „Facebook“ grupėse, Kauno klinikose ir LSMU Kauno ligoninės filiale P. Mažylio gimdymo namuose. Tyrime dalyvavo 753 moterys. Potrauminio streso simptomams vertinti naudota Sičio gimdymo traumų skalė, taip pat buvo pateikiami sociodemografiniai ir su gimdymu susiję klausimai. Tiriamosios turėjo galimybę atsakyti ir į atviro tipo klausimą apie COVID-19 pandemijos poveikį jų gimdymo patirčiai. Į šį klausimą savo nuomonę pateikė 381 moteris. Potrauminio streso simptomų skirtumai pagal sociodemografinius ir su gimdymu susijusius rodiklius buvo analizuojami naudojant Mano-Vitnio ir Kruskalio-Voliso testus. Ryšys tarp su gimdymu susijusių potrauminio streso simptomų ir santykio su sveikatos priežiūros specialistais bei vyru arba partneriu vertintas naudojant Spirmeno koreliacijos koeficientą. Kokybinių tyrimo duomenų analizei taikytas induktyviosios turinio analizės metodas. Rezultatai. Kiek daugiau nei ketvirtadalis moterų gimdymo metu jautė pavojų savo arba savo vaiko sveikatai ar gyvybei. Kiek daugiau nei du trečdaliai moterų po gimdymo jautė pasikartojančius neigiamos patirties išgyvenimus; beveik ketvirtadalis vengė su gimdymu susijusių prisiminimų. Kiek mažiau nei du trečdaliai jautė neigiamus su gimdymu susijusius jausmus, kaltino save ir aplinką dėl įvykių gimdymo metu, nesidomėjo veiklomis. Kiek daugiau nei pusė respondenčių per pastarąją savaitę jautėsi susijaudinusios. Beveik pusė tiriamųjų, patyrusių bent vieną iš potrauminio streso simptomų, jautė distresą ir neigiamą simptomų poveikį kasdieniam gyvenimui. Visus potrauminio streso sindromo diagnostikos kriterijus atitiko 7,97 proc. moterų. Geresnis santykis gimdymo metu su sveikatos priežiūros specialistų komanda ir vyru arba partneriu buvo susijęs su mažesniu potrauminio streso simptomų skaičiumi. Moterų gimdymo patirtis per COVID-19 pandemiją apibūdinta trimis temomis: socialinė izoliacija ir atskirtis; fizinė savijauta ir psichologinė būsena; bendravimas su sveikatos priežiūros specialistais. Išvada. Maždaug trys ketvirtadaliai COVID-19 pandemijos laikotarpiu gimdžiusių tiriamųjų per pastarąją savaitę nors kartą jautė bent vieną su gimdymu susijusį potrauminio streso simptomą ir apie keturi penktadaliai nors kartą per paskutinę savaitę jautė bent vieną bendrą potrauminio streso simptomą.

Published: June 2024

Water pollution, significantly influenced by the discharge of synthetic dyes from industries, such as textiles, poses a persistent global threat to human health. Among these dyes, methylene blue, particularly prevalent in the textile sector, exacerbates this issue. This study introduces an innovative approach to mitigate water pollution through the synthesis of nanomaterials using biomass-derived carbon quantum dots (CQDs) from grape pomace and watermelon peel. Utilizing the hydrothermal method at temperatures between 80 and 160 °C over periods ranging from 1 to 24 h, CQDs were successfully synthesized. A comprehensive characterization of the CQDs was performed using UV–visible spectroscopy, Fourier-transform infrared spectroscopy, dynamic light scattering, Raman spectroscopy, and luminescence spectroscopy, confirming their high quality. The photocatalytic activity of the CQDs in degrading methylene blue was evaluated under both sunlight and incandescent light irradiation, with measurements taken at 20 min intervals over a 2 h period. The CQDs, with sizes ranging from 1–10 nm, demonstrated notable optical properties, including upconversion and down-conversion luminescence. The results revealed effective photocatalytic degradation of methylene blue under sunlight, highlighting the potential for scalable production of these cost-effective catalytic nanomaterials for synthetic dye degradation.

Authors: Moodley Miranda , Jaftha Jacob , Mhakure Duncan
Published: June 2024

Mathematical modelling (MM) is not widely used in South African higher education currently, but has the potential to improve students' conceptual understanding and ability to apply mathematics. Various measures are used to teach MM however, there is no consensus on an ideal model. Therefore, this meta-analysis examines and synthesizes methods used to teach MM in higher education in South Africa. The main findings show that a variety of methods are used, both standardized and non-standardized, to teach MM and often results in improved mathematical understanding. However, more research on mathematical modelling as a teaching strategy using standardized measures is needed in higher education.

Collapsing a V-sign, one 1s plus one 1s gives one 2s and not two. One and two is inside essence to de-model as the outside existence 1s and 2s adding to 3s where one and two only add with like units. 8 push-away 2s, 8/2, recounts 8 in 2s, and ‘demodels’ division as a broom. 4times push-back 2s, 4x2, unites 2s into a stack, and demodels multiplication as a lift. The recountformula 8 = (8/2)x2, or T = (T/B)xB, solves STEM proportionality equations as ‘ux2 = 8’ by recounting 8 in 2s, u = 8/2. Subtraction demodels as a rope to pullaway the stack so the unbundled becomes negatives, decimals, or fractions: 7 = 4B-1 = 3B1 = 3 . 2s. 4 is a BundleBundle-square solving quadratics. On a ten-by ten Bundle-Bundle ‘BBBoard’, bundle-numbers with units as 2 3s and 4 5s add next-to as 8s (integral calculus), or on-top as 3s or 5s or tens. Recounting physical units gives per-numbers or fractions, 3m/5s or 3m/5m, also adding by integral calculus.

Climate change is one of the most urgent and challenging issues in Canada. In this study, high-resolution climate projections over Canada have been developed through the WRF model. The spatial and temporal variations of Canada’s temperature and precipitation in the 21st century have been comprehensively analyzed. It is found that the annual mean temperature over Canada is projected to increase by [1.53, 1.98], [2.51, 3.86], and [2.94, 6.19]°C in the 2030s, the 2050s, and the 2080s under RCP4.5 and RCP8.5 respectively, with the largest increase in winter. The annual total precipitation is projected to increase by [16.33, 68.96], [64.80, 121.62], and [123.62, 184.33] mm in three future periods under RCP4.5 and RCP8.5 respectively. It is also found that sea surface temperatures (SST) anomalies and 500 hPa geopotential height (GPH) have strong impacts on Canada’s annual and seasonal precipitations. The results can provide valuable information for mitigation and adaptation of climatic changes in a Canadian context.

Left ventricular apical hydatid cyst - A rare case report
Authors: Le Thao
Published: June 2024

ABSTRACT

Cardiac hydatid cyst is an extremely rare manifestation of cystic echinoccococis, but without prompt diagnosis and management, it can be fatal. Despite the absence of standardized guidelines, an early, complete surgical removal in conjunction with anthelmintic therapy plays a central role and is associated with an excellent prognosis. We report an indigenous case of left ventricular apical hydatid cyst in a 75 - year - old female who presented with atypical symptoms including abnormal fatigue and increasing exercise intolerance. Although serological tests were negative, imaging modalities revealed a 36 x 30 mm oval structure in the left ventricular apex, suggesting a type I hydatid cyst. A single encapsulated cyst was surgically removed through a median sternotomy under cardiopulmonary bypass. Histopathological analysis confirmed a hydatid cyst, and Echinococcus ortleppi was identified. The patient was discharged without incident and was prescribed 3 cycles of Albedazole.

Methods: This is a cross-sectional descriptive study, combining quantitative and qualitative methods. Quantitative data was collected via a self-administered questionnaire among 25 staffs directly managing medical devices and 124 medical devices records. Qualitative data was collected from four in-depth interviews and two focus group discussions. Main findings: Medical devices invested by the hospital (59.7%), low frequency of use of medical devices accounted for 0%, and unused equipment accounted for 0%. Dossiers of incomplete equipment, mainly lack of operational logs and documents for maintenances and repairs; medical devices with qualified certificates accounted for 100%; all equipments are built using procedures and operating procedures; but inspections and verifications are only carried out periodically and incompletely; post-repair inspections have not been carried out, equipment maintenance costs still remains low. However, maintenance budget constraints were observed, and the information system and maintenance work did not fully meet requirements due to various reasons, primarily financial issues. Hospital chairmans identified financial concerns as a key issue and planned to solve them in the near future to utilize the quality of medical devices according to regulations. Key words: Medical devices, influenced factor, Tra Vinh province hospital.

This article analyses how transnational co-productions render Irish history audio-visually by comparing the soundtracks of
Some Mother’s Son
(1996) and
The Wind that Shakes the Barley
(2006). The puzzle is whether history films can enhance immersive perceptual experiences of place by using local music, while catering to the audiovisual skills and expectations of global audiences. The study compares Bill Whelan’s and George Fenton’s respective soundtracks. On the one hand, Whelan’s avowedly Irish soundtrack performed by the Irish Film Orchestra with virtuosos from the Riverdance Orchestra crowds the images and prescribes audience feelings. On the other, Fenton lightly melds classical film orchestration with Irish melody and instrumentation and
The Wind that Shakes the Barley
blends diegetic singing with its more spacious soundtrack. The conclusion is that combining local instruments and diegetic song with limited cinematic orchestration succeeds better than neo-traditional instrumentation in screening Irish history.
A Candidate Period of 4.605 Days for FRB 20121102A and One Possible Implication of Its Origin

Published: June 2024

A firm establishment of the presence or the lack of periodicity in repeating fast radio bursts is crucial for determining their origins. Here, we compile 1145 radio bursts of FRB 20121102A with fluence larger than 0.15 Jy ms from observations using the Five-hundred-meter Aperture Spherical radio Telescope, the Arecibo Observatory, the Green Bank Telescope, the Effelsberg Telescope, the MeerKAT Telescope, the Lovell Telescope, the Deep Space Network 70 m radio telescopes, the Very Large Array, and the Westerbork Synthesis Radio Telescope, spanning the time interval of MJD 57175−58776. A quasi-period of

days are found through the phase-folding probability binomial analysis. The former is consistent with previous findings and the latter is new. The 4.605 day periodicity is more obvious in high-energy bursts with fluence larger than 1 × 1038 erg. The presence of these (candidate) quasi-periods, together with the corresponding width of burst accumulation in the phase space, are consistent with the bursts originating from a binary degenerate star system with a close-by planet around the primary neutron star.
Radio Images inside Highly Magnetized Jet Funnels Based on Semianalytic GRMHD Models
Authors: Ogihara Taiki , Kawashima Tomohisa , Ohsuga Ken
Published: June 2024

By performing general-relativistic radiative transfer calculations, we show the radio images of relativistic jets including highly magnetized regions inside jet funnels, based on steady, axisymmetric, and semianalytic general-relativistic magnetohydrodynamics models. It is found that multiple ring images appear at the photon frequency of 230 GHz for nearly pole-on observers, because of the strong light-bending effect on photons generated at the separation surface, which is the boundary between the inflow and outflow flows in the jet funnel. A bright teardrop-shaped component, which extends from the bright rings of the separation surface, also appears in the counterjet region. The diameter of the brightest outermost ring originated from the counterjet is ∼60 μas, which is consistent with the ringlike images of M87 at 86 GHz observed with GMVA, the Atacama Large Millimeter/submillimeter Array, and the Greenland Telescope, whose ring diameter is

. The thinner and smaller-diameter rings are exhibited when the black hole spin magnitude is higher. These morphological features are expected to appear without being prominently affected by the detailed magnetohydrodynamic plasma parameters of our general-relativistic ideal magnetohydrodynamic (GRMHD) jet model, since the location of the separation surface is mainly regulated by the black hole spin. Our GRMHD model and the emission features of the images in the horizon-scale, highly magnetized jet funnel may be tested by future observations, e.g., the next-generation Event Horizon Telescope and the Black Hole Explorer.

Published: June 2024

The presence of young stellar populations in the Large Magellanic Cloud cluster NGC 1783 has caught significant attention, with suggestions ranging from it being a genuine secondary stellar generation to a population of blue straggler stars or simply contamination from background stars. Thanks to multiepoch observations with the Hubble Space Telescope, proper motions for stars within the field of NGC 1783 have been derived, thus allowing accurate cluster membership determination. Here, we report that the younger stars within NGC 1783 indeed belong to the cluster and their spatial distribution is more extended compared to the bulk of the older stellar population, consistent with previous studies. Through N-body simulations, we demonstrate that the observed characteristics of the younger stars cannot be explained solely by blue straggler stars in the context of the isolated dynamical evolution of NGC 1783. Instead, accretion of the external, low-mass stellar system can better account for both the inverse spatial concentration and the radial velocity isotropy of the younger stars. We propose that NGC 1783 may have accreted external stars from low-mass stellar systems, resulting in a mixture of external younger stars and blue straggler stars from the older bulk population, thereby accounting for the characteristics of the younger sequence.
No Top-heavy Stellar Initial Mass Function Needed: The Ionizing Radiation of GS9422 Can Be Powered by a Mixture of an Active Galactic Nucleus and Stars

Published: June 2024

JWST is producing high-quality rest-frame optical and UV spectra of faint galaxies at z > 4 for the first time, challenging models of galaxy and stellar populations. One galaxy recently observed at z = 5.943, GS9422, has nebular line and UV continuum emission that appears to require a high ionizing photon production efficiency. This has been explained with an exotic stellar initial mass function (IMF; Cameron et al. 2023a), 10–30x more top-heavy than a Salpeter IMF. Here we suggest an alternate explanation to this exotic IMF. We use a new flexible neural net emulator for CLOUDY, Cue, to infer the shape of the ionizing spectrum directly from the observed emission line fluxes. By describing the ionizing spectrum with a piecewise power law, Cue is agnostic to the source of the ionizing photons. Cue finds that the ionizing radiation from GS9422 can be approximated by a double power law characterized by

2 in a 65%/35% ratio. This suggests a significantly lower nebular continuum contribution to the observed UV flux (24%) than a top-heavy IMF (≳80%), and hence, necessitates a damped Lyα absorber to explain the continuum turnover bluewards of ∼1400 Å. While current data cannot rule out either scenario, given the immense impact the proposed top-heavy IMF would have on models of galaxy formation, it is important to propose viable alternative explanations and to further investigate the nature of peculiar high-z nebular emitters.

Published: June 2024

In the effort to combat SARS-CoV-2 infection, researchers are currently exploring the repurposing of conventional antiviral drugs, despite their limited efficacy. The SARS-CoV-2 virus encodes a papain-like protease (PLpro), which not only plays a crucial role in viral replication but also cleaves ubiquitin and interferon-stimulated gene 15 protein (ISG15) from host proteins, making it a prime target for the development of new antiviral medications. In this study, we conducted a multi-step in silico screening to identify novel, noncovalent PLpro inhibitors. Curcumin, an antioxidant derived from turmeric rhizomes (Curcuma longa L.), has undergone extensive preclinical investigations and shown significant efficacy against viruses and other ailments in both laboratory and animal studies. However, the pharmacological limitations of curcumin have prompted the synthesis of numerous novel curcumin analogs, necessitating evaluation for their therapeutic potential. The selectivity of the top-scoring compounds was assessed through molecular docking studies and molecular dynamics simulations to determine their binding affinity to PLpro. As a result, we identified 20 potential, selective PLpro inhibitors, from which the top two compounds (THA111 and THHGV6) were selected based on their binding free energy values towards PLpro as estimated by MM-PBSA calculations. These selected candidates demonstrate promising activity against the protein, with binding free energy values ranging from approximately −105 to −108 kJ/mol, and largely adopt a similar binding mode to known noncovalent SARS-CoV-2PLpro inhibitors (GRL0617 = −100.98 kJ/mol). We further propose these two most promising compounds for future in vitro evaluation. The findings for the top potential PLpro inhibitors have been deposited in a database (Curcumin Research Center) to aid research on anti-SARS-CoV-2 drugs.

Published: June 2024

Chrysosplenium guangxiense H.G.Ye & Gui C.Zhang was first described as a new species in 1994 but later synonymized in the Flora of China treatment with C. glossophyllum H.Hara. Plastid genomes and nrDNA sequences were used to infer the phylogenetic relationships of selected taxa in Chrysosplenium. Our phylogenetic analyses revealed that C. guangxiense belongs to sect. Alternifolia, is closely related to Chrysosplenium hydrocotylifolium H.Lév. & Vaniot but distant from C. glossophyllum. Morphologically, C. guangxiense could be easily distinguished from C. glossophyllum by having robust rhizomes, basal leaves with a long cuneate base and fewer teeth in the margin, curled sepal margins, and red, larger seeds. It could also be easily distinguished from C. hydrocotylifolium by possessing long elliptic leaves and a long cuneate leaf base. Along with the phylogenetic studies, the complete plastid genome of C. guangxiense was also reported. The plastid genome was 154,004 bp in length and comprised two inverted repeats (IRs) of 28,120 bp, separated by a large single-copy of 80,646 bp and a small single-copy of 17,118 bp. A total of 111 functional genes were discovered, comprising 78 protein-coding genes, 29 tRNA genes, and four rRNA genes. Based on assessment of morphological and molecular data Chrysosplenium guangxiense H.G.Ye & Gui C.Zhang is resurrected from C. glossophyllum H.Hara at species level. A global conservation assessment classifies C. guangxiense as Vulnerable (VU).
