Authors: Siddique Raiyan , Ashikur M. R. , Hamida Taspiya , Islam Mohammad Azharul
Published: November 2024

The persistence of coastal ecosystems is jeopardized by deforestation, conversion, and climate change, despite their capacity to store more carbon than terrestrial vegetation. The study’s objectives were to investigate how spatiotemporal changes impacted blue carbon storage and sequestration in the Satkhira coastal region of Bangladesh over the past three decades and, additionally to assess the monetary consequences of changing blue carbon sequestration. For analyzing the landscape change (LSC) patterns of the last three decades, considering 1992, 2007, and 2022, the LSC transformations were evaluated in the research area. Landsat 5 of 1992 and 2007, and Landsat 8 OLI-TIRS multitemporal satellite images of 2022 were acquired and the Geographical Information System (GIS), Remote Sensing (RS) techniques were applied for spatiotemporal analysis, interpreting and mapping the output. The spatiotemporal dynamics of carbon storage and sequestration of 1992, 2007, and 2022 were evaluated by the InVEST carbon model based on the present research years. The significant finding demonstrated that anthropogenic activity diminished vegetation cover, vegetation land decreased by 7.73% over the last three decades, and agriculture land converted to mariculture. 21.74% of mariculture land increased over the last 30 years, and agriculture land decreased by 12.71%. From 1992 to 2022, this constant LSC transformation significantly changed carbon storage, which went from 11706.12 Mega gram (Mg) to 9168.03 Mg. In the past 30 years, 2538.09 Mg of carbon has been emitted into the atmosphere, with a combined market worth of almost 0.86 million USD. The findings may guide policymakers in establishing a coastal management strategy that will be beneficial for carbon storage and sequestration to balance socioeconomic growth and preserve numerous environmental services.

Published: November 2024

Recently, copper oxide–ferric oxide nanocomposites (CuO/Fe2O3-NCs) have gained popularity and are widely employed in various applications. However, their effectiveness against phytopathogens has not been studied yet. This study investigates the synthesis and characterization of CuO/Fe2O3-NCs using the hydrothermal technique. X-ray diffraction (XRD), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), and Fourier-transform infrared spectroscopy (FTIR) were used to characterize the produced nanocomposite (NC). EDX and TEM analyses revealed the presence of Cu, Fe, and O elements. The NC had a polygonal shape with sides around 12 nm, spherical CuO particles of 7–10 nm, and plate-like Fe2O3. XRD measurements confirmed the crystal and hexagonal structures of CuO and Fe2O3. The XRD patterns of CuO/Fe2O3 showed the characteristic peaks of (−111) and (004) reflections for CuO at 35.69° and 37.73°. The FTIR spectra showed characteristic lines at 525 and 567 cm−1 for the Cu–O bond and Fe–O stretching modes of Fe2O3, respectively. The antifungal activity of CuO/Fe2O3-NCs showed significant growth inhibition of Fusarium oxysporum, Rhizoctonia solani, and Botrytis cinerea by up to 71, 50, and 81%, respectively, at 100 µg/mL. At 50 µg/mL, the antibacterial test revealed inhibition zones of 12.33 mm for Pectobacterium carotovorum, 9.33 mm for Streptomyces scabies, 10.67 mm for Pectobacterium atrosepticum, and 14.67 mm for Ralstonia solanacearum. The results show that CuO/Fe2O3-NCs can efficiently suppress the growth of various fungal and bacterial strains, making them potential antimicrobial agents against phytopathogenic microorganisms.

Research subject. Minerals of Cu from the Mikheevskoe gold-copper-porphyry deposit in the Southern Urals. Aim. To obtain preliminary data on the isotopic composition of Сu in minerals of various ore types from the largest porphyry deposit of the Urals followed by their interpretation. Methods. The 65Cu/63Cu isotope ratio values were determined using a multicollector inductively coupled plasma mass spectrometer Neptune Plus at the Research Center “Geoanalytik” (IGG of Ural Branch of the Russian Academy of Sciences). In total, 12 samples of three main technological ore types from this deposit were analyzed. Results. The δ65Cu values in the minerals of sulfide, friable, and oxidized ores ranged from –0.36 to +0.25‰ (chalcopyrite, fahlore), from –0.64 to +0.68‰ (bornite, chalcocite, pyrite), and from –2.14 to +0.30‰ (malachite, azurite), respectively. Conclusions: The absence of wide variations in δ65Cu values indicates the formation of the deposit under the conditions of a limited number of stages of hydrothermal ore formation, associated with the evolution of a single hydrothermal system. The obtained data agree well with the values of δ65Cu in porphyry-type deposits from different regions of the world. The conducted study contributes to the current knowledge on behavior of Cu-isotopes in minerals from ore deposits.

Background. Sexual abuse in children can sometimes result in sexually transmitted infections (STIs), which can serve as crucial forensic evidence. Although PCR methods are now accepted as the gold standard for STI screening, they have not yet widely replaced traditional culture methods in Türkiye. This study aims to assess the necessity of implementing PCR-based STI testing at Child Advocacy Centers in Türkiye, where such testing is not routinely available.
Methods. Conducted between February and November 2023, this study included children who presented to the Child Advocacy Center of Marmara University Pendik Training and Research Hospital. High-risk victims were identified based on criteria including a history of penetrative sexual abuse and factors such as multiple perpetrators or significant age disparity. Serological tests and genital swabs were collected and analyzed using both bacterial culture methods and a comprehensive STI PCR panel.
Results. The study included 20 victims, with a median age of 16 years. STI PCR testing detected pathogens in 19 out of 21 samples, including Chlamydia trachomatis (20%) and Neisseria gonorrhoeae (5%). In contrast, culture methods identified no sexually transmitted pathogens.
Conclusion. PCR testing demonstrated significantly higher sensitivity for detecting STIs compared to traditional bacterial culture methods, as expected. Implementing PCR-based STI testing in Child Advocacy Centers is an urgent and essential need for providing an accurate diagnosis and robust forensic evidence, enhancing the care and legal protection of sexually abused children.

Published: November 2024

En esta revisión se describen algunos aspectos para comprender los efectos de las hormonas y su efecto en el funcionamiento cerebral, utilizando para ello el estudio de la conducta sexual femenina (CSF). Las hormonas esteroides, como el estradiol (E2) y la progesterona (P), juegan un papel importante en el desarrollo y la expresión de dicha conducta. Por ejemplo, se conoce que el E2 prepara al sustrato neural involucrado en la regulación de la CSF (área preóptica; APO o el hipotálamo; HT, etc.) mientras que la P es quien dispara la expresión de dicha conducta. Además, se ha planteado que compuestos con diferentes estructuras químicas como: péptidos (hormona liberadora de gonadotropinas; GnRH, leptina, apelina-13), aminas biogénicas (adrenalina), prostraglandina E2 (PGE2), segundos mensajeros (adenosín monofosfato cíclico; AMPc, guanosín monofosfato cíclico; GMPc, etc.), pueden sustituir al efecto inductor de la P sobre la expresión de la CSF. Además, se describen algunos estudios realizados desde un punto de vista hormonal y celular en roedores, los cuales han contribuido al entendimiento de la fisiología reproductiva. También se describen algunos de los mecanismos intracelulares involucrados en la regulación de la expresión de dicho comportamiento como: a) la fosforilación de proteínas, b) los efectos de leptina y apelina-13, y su posible comunicación cruzada con hormonas esteroides. Finalmente, c) describiremos cómo los astrocitos, al liberar neurotransmisores en respuesta a diversas hormonas, podrían modular a las neuronas del HT involucradas en la liberación de la GnRH, misma que se encuentra en sincronía con la expresión de la CSF.

Published: November 2024

Micromixers are chemical processing devices with complex flow patterns applied for both mixing and reaction of chemical species. In current research, laminar reacting multicomponent flows are considered. Despite the laminar streaming regime (e.g., Re = 186), there exist secondary flow microstructures. For this setup, accurate predictions of those structures are possible with a large-eddy simulation on a fine mesh resolving till the Batchelor microscales. Utilizing the open-source lattice Boltzmann method (LBM) framework, OpenLB, a benchmark simulation of the reacting micromixer, is re-established with new, more precise computation results. In this context, a Schmidt-number-based stabilization method for LBM-discretized reactive advection–diffusion equations by laminar secondary flow structures is used. A convergence study is performed, which is also a novelty. All computations have been performed on the high-performance computing cluster HoreKa using up to 160 NVIDIA A100 graphics processing units.
One-Equation Amplification-Factor-Transport Transition Model for High-Speed Flows
Authors: Liu Zaijie , Huang Hexia , Tan Huijun
Published: November 2024

A one-equation transition model is proposed for high-speed transitional flows. The model is based on the amplification-factor-transport framework and involves only one transport equation for the amplification factor of streamwise instabilities. A new algebraic intermittency factor is established and applied to a turbulence model to predict transition, and the model is tested by applying it to several cases over a wide speed range. Comparisons with linear stability theory and available experimental data indicate that the model handles first- and second-mode-induced transitions in supersonic and hypersonic flows and reasonably captures the effects of Mach number, wall-to-edge temperature ratio, and nose bluntness. The new one-equation model offers reduced computational burden and simpler implementation while retaining a reasonable prediction accuracy.
Review of Wavenumber-Frequency Spectrum Models of Turbulent Boundary-Layer Wall Pressure Fluctuations
Authors: Zhao Kun , Li Yimeng , Pei Rui , Li Hongzhou , Bennett Gareth J.
Published: November 2024

Turbulent boundary layer wall pressure fluctuations are of significant concern in acoustic engineering for both high-speed airborne and underwater vehicles, and the modeling of the associated wavenumber-frequency spectra has been extensively studied. In this paper, a review of 12 models developed between 1964 and 2017 has been conducted, and both the 2D and 1D forms investigated. In this work, fundamental concepts are introduced, followed by a classification of the models into two categories, that is, Corcos-type and non-Corcos-type models. Both the 2D and 1D forms of the 12 models are individually introduced in chronological order. To evaluate these models, comparisons of the 2D and 1D wavenumber-frequency spectra at different speeds and frequencies were conducted. Unlike Corcos-type models, non-Corcos-type models are grounded in a stronger theoretical foundation, with some models accurately reflecting acoustic region characteristics. Corcos-type models exhibit good consistency, however, they require an auto-spectrum as a necessary input, which makes them semiempirical models. In addition, the models within the Corcos-type and the non-Corcos-type were also compared, respectively, and a few important conclusions were accordingly made. The research output from this paper can provide an important practical engineering reference for studies associated with acoustic engineering, such as aircraft cabin noise and submarine hydrodynamic noise.

In the presented work, the issues of measuring the thrust force of spacecraft thrusters are considered. A program for determining the thrust force based on machine vision has been developed. A mathematical model of the mechanical part of the stand has been compiled. Numerical modeling of the compiled system of equations is carried out. The simulation results are processed using the developed program. The relative error of misalignment is no more than 5 %. Field experiments are carried out and the thrust levels of the ion thruster are measured. A comparative analysis of the experimental results obtained with a mathematical model is shown. Experimental studies have been conducted to determine the thrust of a prototype arcjet thruster using a stand based on machine vision and using a stand based on a displacement sensor. The discrepancy in the results of the thrust force is  5,6 %.

In this paper, experimental waveforms of the bifurcation phenomena in a Duffing oscillator weakly damped by viscous friction. The bifurcation points are found by solving the numerical solution of a harmonically linearized system with respect to the square of the frequency and the square of the amplitude. Approximate dimensionless expressions for amplitudes and their corresponding frequencies at the bifurcation points are proposed. The comparison of experimental and theoretical amplitudefrequency characteristics and their values at these points is given.

Objetivo: Avaliar os impactos da insatisfação corporal, dos fatores socioculturais e do estado nutricional sobre o comportamento de risco para transtornos alimentares em acadêmicos do curso de Nutrição de uma Universidade do Vale do Submédio São Francisco. Métodos: Trata-se de um estudo transversal, com 60 universitários, sendo avaliados a caracterização do perfil socioeconômico, o comportamento de risco para transtorno alimentar, a insatisfação corporal e o estado nutricional. Foram observadas as frequências absolutas e relativas de cada variável, a normalidade dos dados pelo teste de Shapiro Wilk (p<0.0-) e as variáveis qualitativas foram observados pelo teste Qui-quadrado (p<0.05). O estudo foi aprovado pelo Comitê de Ética em Pesquisa. Resultados: Da amostra estudada, 16,6% apresentaram algum grau de insatisfação corporal e 26,7%, comportamento de risco para transtorno alimentar. A análise estatística supõe possível associação entre o comportamento de risco para TA e a presença de insatisfação corporal (p<0.05). Conclusão: Uma abordagem incisiva sobre os comportamentos alimentares disfuncionais e a promoção da imagem corporal positiva são essenciais para os estudantes de nutrição, com vistas à prevenção de danos futuros e à garantiada prática profissional com integralidade e humanização.
Imaging-tracked progression of primary leptomeningeal gliomatosis: A case report
Authors: Nomura Noriaki , Nagasaka Shohei , Suzuki Kohei , Yamamoto Junkoh
Published: November 2024

Background:

Primary leptomeningeal gliomatosis (PLG) is a rare neoplasm characterized by the diffuse spread of glial tumor cells throughout the leptomeninges without any evidence of a primary tumor source in the brain or spinal cord parenchyma. Here, we present a case of PLG potentially linked to prior interventional radiotherapy.

Case Description:

The patient was a 75-year-old woman with a history of interventional radiology for a left internal carotid cavernous sinus fistula 13 years before presentation. Routine follow-up fluid-attenuated inversion recovery magnetic resonance imaging revealed a high intensity region spreading from the deep white matter of the subventricular zone (SVZ) to the insular cortex and medial temporal lobe. Subsequently, contrast-enhanced T1-weighted imaging revealed an enhanced effect consistent with extensive leptomeninges extending from the basilar cistern to the left Sylvian fissure. The patient underwent surgery, and subsequently histological examination of extracted tissue revealed a glioblastoma (GBM). Despite postoperative concurrent chemoradiotherapy and adjuvant temozolomide chemotherapy, the tumor increased in size, and the patient died 2 months postoperatively.

Conclusion:

This case highlights the importance of careful follow-up and early therapeutic intervention in PLG, as it can be difficult to diagnose leptomeningeal lesions alone. This case also raises the possibility of radiation-induced GBM, and the criteria for diagnosis were fully met. The progression of PLG from the SVZ to the leptomeningeal site was tracked using imaging, providing valuable insights into the pattern of spread of this rare condition.
An analysis of the moderating effect of vocational calling on the relationship between the working environment and turnover intentions of school meal cooking workers: focusing on the Gyeonggi-do region
Authors:   The Table and Food Coordinate Society of Korea, Choi Jeong-Hee
Published: November 2024

Frequent replacement of school food service cooks causes serious operational difficulties. The purpose of this study was to find a way to decrease the turnover rate by exploring the factors affecting the turnover intention, the working environment of school cooks, and the moderating effect of vocational calling. This study was conducted for two weeks, from December 4 to December 17, 2023, using the Google questionnaire method for elementary, middle, and high school cooks in Gyeonggi-do. A total of 230 people participated in this survey. Empirical analysis was conducted on 204 valid questionnaires. The results of this study confirmed that there was a negative effect in the relationship between the working environment and turnover intention. Furthermore, it was found that sense of vocational calling was a moderating effect in the relationship between the working environment and turnover intention. This study identified that school food service workers’ sense of vocational calling was an important factor in mitigating the relationship between working environment and turnover intention. These findings suggest that, to increase employee retention, schools need policies to increase workers’ sense of vocational calling.
Machine Learning Committee Neural Network Potential Energy Surfaces for Two-Dimensional Metal-Organic Frameworks

Published: November 2024

Two-dimensional (2D) layered metal-organic frameworks (MOFs) are gaining attention due to their unique structural and electronic properties with promising applications in compact electronic device fabrication. Long-time and large-scale molecular dynamics simulation of these materials can enhance and expedite the mapping out of their structure-property-function relationships for these applications. To make such simulations more feasible, herein, we construct a high-dimensional committee neural network potential (CNNP) for archetypal 2D MOFs Ni3(HIB)2 and Ni3(HITP)2 where HIB=hexaiminobenzene and HITP=hexaiminotriphenylene. We harness the power of active learning and committee neural networks to obtain a CNNP model using only hundreds of snapshots from ab initio molecular dynamics (AIMD) trajectories. The developed CNNP models allow for simulations of thousands of atoms over extended timescales, which is typically unfeasible with AIMD simulations, while maintaining the accuracy of the reference data. Our stable MD simulations based on the developed CNNP model reveal the flexible nature of the studied 2D MOFs at room temperature, including puckered layers, as opposed to the planar ones from 0 K electronic structure calculations. Furthermore, our model demonstrates transferability between bulk and monolayers, as well as different organic linkers. As the first model of its kind, we show that the high-dimensional CNNP models could be a reliable and effective approach for future studies on 2D MOFs.
