АРЕАЛ КОГТИСТОЙ БУРОЗУБКИ SOREX UNGUICULATUS И СТАТУС ВИДА В ТАКСОЦЕНАХ ЗЕМЛЕРОЕК СЕВЕРО-ВОСТОЧНОЙ АЗИИ
Authors: В.А. НЕСТЕРЕНКО 
Published: November 2024

Ведущий полуподземный образ жизни Sorex unguiculatus является фоновым видом землероек центральной части Северо-Восточной Азии, и статья посвящена выяснению его статуса в таксоценах землероек в пределах всего уточненного ареала. Выяснено, что конфигурация современного ареала когтистой бурозубки отличается от общепринятого и его становление происходило путем распространения из двух позднеплейстоценовых рефугиумов - материкового и островного. По статусу когтистой бурозубки в таксоценах землероек выделено три области: этот вид является доминантом в маловидовых островных таксоценах, субдоминантом в насыщенных в видовом отношении таксоценах зоны кедрово-широколиственных лесов Уссурийского края и второстепенным видом в зоне взаимопроникновения неморальной и таежной растительности левобережной части Нижнего Приамурья. Дальнейшее расширение ареала когтистой бурозубки в северо-западном направлении маловероятно в силу специфики требований этого вида к типу и структуре почв, существенно меняющихся в условиях появления вечной мерзлоты, и необходимости сосуществования с экологически близким видом - плоскочерепной бурозубкой.
Semi-fossorial Sorex unguiculatus is a common shrew species in the central part of Northeast Asia, and the paper is devoted to elucidating its status in shrew taxocenes within the entire specified range. The configuration of the modern range of the long-clawed shrew differs from the generally accepted one and its formation occurred through distribution from two Late Pleistocene refugiums - mainland and island. According to the status of the long-clawed shrew in the taxocenes, three areas were distinguished: this species is a dominant in low-species insular taxocenes, a subdominant in multispecies taxocenes of coniferous-broad-leaved forests of the Ussuri Territory, and a minor one in the zone of interpenetration of nemoral and taiga vegetation of the left-bank part of the Lower Amur Region. Further northwest expansion of the long-clawed shrew is unlikely due to the specific requirements of this species for the type and structure of soils, which change significantly under the conditions of the appearance of permafrost, and coexistence with an ecologically close species, the flat-skulled shrew.

Рекомендованы виды-индикаторы ранних трендов трансформации экосистем под влиянием антропогенной нагрузки и ассоциации химических элементов, связанные с различными источниками загрязнения. Показана роль методов фитоиндикации при малозаметных изменениях состояния окружающей среды в условиях газоконденсатных месторождений.
Based on long-term research (1993-2022), the content of chemical elements (Na, K, Ca, Cu, Zn, Fe, Pb, Sr, Zr, Cd, Ni, Co, Cr, Ba, Cd, and Mn) has been determined in 17 plant species of the northern West Siberia region. The regional geochemical background of dominant plant species has been established, and an assessment of changes in the chemical composition of plants in the area of oil and gas condensate field development in the northern West Siberia region has been provided. Indicator species reflecting early trends in ecosystem transformation under the influence of anthropogenic load and associations of chemical elements linked to various sources of pollution have been recommended. The role of phytoindication methods has been demonstrated in detecting subtle changes in the environmental state in the conditions of gas condensate field sites.

Published: November 2024

The benefits of cycling as a means of active transport are well known, and there is recent UK Government interest in promoting cycling. Few children in the UK cycle to school, and little research has explored the factors that affect this.This systematic review aimed to identify the barriers and facilitators for children cycling to school in the UK.
We searched seven electronic databases and grey literature for sources, from 2010 onwards. In total 16 papers/articles were included. The capabilities approach (CA) was used as a framework for analysis to identify personal, social, and environmental barriers and facilitators. Personal barriers and facilitators centred around gender and age, but also related to concerns about safety or confidence. Social barriers and facilitators related to parental attitudes and wider social norms. Environmental barriers included distance, infrastructure, and deprivation. Using the CA revealed the complex interweaving of factors that must be addressed by interventions seeking to promote children’s cycling to school. For example, parental fears about children’s safety when cycling are linked to prevailing social norms and to local cycling infrastructure. Local authorities can promote cycling by developing well-connected accessible and safe cycle routes, but this alone is likely to be insufficient. Schools can enhance personal, social, and environmental conver-sion factors by developing and implementing active transport plans, increasing children’s personal competences, reassuring parental fears, and providing secure storage and changing facilities. Further research exploring how barriers can be addressed, together with local and national policies and targeted funding which focus on facilitation of cycling to school are warranted.

Currently, the electromagnetic characteristics of various materials, including polymers, are being widely studied with the aim of using them as radio-absorbing coatings in electronics products. One such material is pyrolyzed polyacrylonitrile (PPAN). A model of electromagnetic wave absorption by PPAN layers with electrical conductivity of 72 and 180 S/m and a layer width of 0.15 to 2 mm, including those containing a metal filler (the so-called PPAN-based metal composite), in the frequency range of 3–50 GHz is considered. The simulation was performed in the COMSOL Multiphysics software package.A comparison of the experimental results with the data obtained during the simulation was carried out for such parameters as reflection, transmission and absorption. The conclusions obtained from the analysis of simulation data coincide with the results of practical experiments. Analysis of the model showed the convergence of modeling results with experimental data at a qualitative level.

Published: November 2024

Background: Chitosan due to biodegradable and non-toxic characteristics has versatile applications. Extraction and characterization of Chitosan from Snail Shells In January, 2023 Achatina fulica was performed.
Methods: A chemical process involving demineralization and deproteinization was utilized to extract 2000g Chitin from Achatina fulica shells. To produce chitosan, the chitin was subjected to deacetylation. The chitosan was subsequently characterized using Fourier Transform Infrared spectroscopy, X-ray diffraction, and Scanning Electron Microscopy. The physicochemical charactristics and mineral compositionswere investigated and the data were analyzed using the Statistical Package for Social Sciences (SPSS) software version 20.0.
Results: The chitosan obtained from the process was 75%. It exhibited a Degree Of Deacetylation of 82.31%, a molecular weight of 2.65×105 g/mol, an intrinsic viscosity of 1,007.2 mg/g, and a solubility of 70%. The pH value of chitosan in acetic acid solution was recorded at 6.38, with a solubility of 70%. The proximate analysis revealed moisture, ash, fat, protein, crude fiber, and carbohydrate contents of 0.32, 0.72, 2.01, 0.13, 0.15, and 96.67%, respectively.The mineral analysis revealed sodium, potassium, calcium, magnesium, phosphorus, iron, and zinc concentrations of 32.10, 21.80, 721, 288.60, 123.75, 41.77, and 8.48 mg/g, respectively. X-ray diffraction analysis identified the region characterized by the presence of calcite and calcium phosphate, indicating residual minerals in the extracted chitosan, which contribute to its crystalline structure. Fourier Transform Infrared spectroscopy demonstrated functional groups such as amino and hydroxyl groups, whereas Scanning Electron Microscopy reported an irregular particle size with rough surfaces and a microfibrillar crystalline structure.
Conclusion: The current investigation has the potential to promote the sustainable use of a locally abundant yet underutilized resource, assisting in waste reduction and creation of innovative bioactive materials which could be applied in food preservation, pharmaceuticals, and medical devices.

Published: November 2024

This research aims to investigate the ability of teachers in designing sound of green-based PjBL STEAM learning to empower creative thinking skills and to determine the differences in creative thinking abilities in junior high school students. This study emphasizes the assessment of the effectiveness of project-based STEAM learning based on sound of green in empowering students' creative thinking in natural resource processing, involving 162 students in schools in music tourism attraction villages in Ambon city. The study reports that the respondents' results and creativity levels, including fluency, flexibility, originality, and elaboration among students, were excellent. Overall research results indicate that the majority of students are at a good level after being taught with the sound of green-based PjBL STEAM model. The increase in students' creativity with guidance and direction from teachers, especially in the technical, art, and mathematics stages in STEAM, is evident. Initially, many students lacked fluency, flexibility, originality, and elaboration dimensions in detail, resulting in an inability to generate more ideas and provide answers. Consequently, their originality decreased, and they lacked ideas to further elaborate on the given answers. However, findings from several meetings show a significant improvement among students. This is because implementing project-oriented learning models that empower the environment around students enhances every domain of creativity in science subjects. Additionally, the researcher suggests conducting further research on students' creative thinking processes based on the unique advantages of each school's geographical location. Teachers are expected to better understand students' cognitive, affective, and psychomotor abilities, improving students' creative thinking skills in every dimension of creativity according to the geographical conditions of the learners' environment. Keywords: sound of green STEAM, project learning, creative thinking

Infodemics are the rapid spread of false or misleading information related to public health emergencies, often through digital platforms. They can cause confusion, fear, and even harm to public health. This study investigates the application of sentiment analysis for infodemic management during disease outbreaks. Leveraging the Extended Parallel Process Model (EPPM) of risk communication, the research aims to categorize rumors based on their perceived threat level (high, medium, or low). Machine learning is employed to analyze infodemic text data collected from two Nigerian states (Oyo and Bauchi) to assess threat appraisal according to the EPPM model. The findings can inform targeted interventions for effective infodemic management before, during, and after outbreak of diseases.
Improvements in the manufacture of benzoic acid obtained by catalytic oxidation of toluene
Authors: Poço João Guilherme Rocha , Cella Rodrigo , Derenzo Silas 
Published: November 2024

This study investigates improvements in benzoic acid production through the catalytic oxidation of toluene with cobalt octoate. The oxidation process, which occurs under controlled conditions with temperatures ranging from 130 °C to 165 °C, typically results in a conversion rate of 50% toluene with a selectivity of 80% over benzoic acid. However, various by-products such as benzyl alcohol, benzaldehyde, and benzyl benzoate are also formed, which reduces the overall yield. The work identifies methods to minimize these byproducts, particularly benzyl benzoate, which forms in the distillation column. One strategy investigated involved using additives to inhibit the esterification reaction that produces benzyl benzoate, aiming to improve the selectivity of the oxidation process. Experimental results show that maintaining reaction temperatures between 135 °C and 145 °C in combination with using sodium benzoate as an additive effectively reduces the formation of benzyl benzoate and increases the yield of benzoic acid. Furthermore, increasing the O2/toluene ratio increases the oxidation efficiency.

Abstract

Purpose: Sarcopenic obesity, characterized by increased adiposity with low skeletal muscle mass, contributes to frailty and the development of chronic disease. Data on sarcopenic obesity in survivors of childhood acute lymphoblastic leukemia (cALL) is limited.
Methodology: A cross-sectional study on 65 cALL survivors (7-18 years, >2 years from treatment completion) was conducted on cALL survivors with the primary outcome to determine the prevalence of sarcopenic obesity. Sarcopenic obesity was defined as patients with a positive Fat Mass (FM) z-score with a negative Appendicular Lean Body Mass (APLBM) z-score, measured using Dual-Energy Xray Absorptiometry (DXA) scan. In addition, we assessed the factors associated with sarcopenic obesity by multivariable regression analysis.
Results: The mean (±SD) age was 12.9 (±3.2) years, the median (Interquartile Range) time since diagnosis was 6.5 (5.9;8) years, and 66% received cranial radiotherapy. Central obesity, insulin resistance, and metabolic syndrome were seen in 21.5%, 23.1%, and 21% respectively. DXA-derived body composition variables revealed higher fat percentage despite normal body mass index (BMI) and lower muscle mass compared to the general population. Sarcopenic obesity was seen in 21 (32%) of survivors. On multivariable regression analysis, age at diagnosis (OR: 0.95 (95% CI: 0.92-0.98), p=0.02), central obesity (OR: 18.99 (95% 2.32-155.5), p=0.006) and insulin resistance (OR: 10.2 (95% CI: 1.75-59.09), p=0.01) were associated with sarcopenic obesity.
Conclusions and Implications for cancer survivors: Sarcopenia, an early clinical indicator for metabolic disease despite normal BMI, was significantly worse in children diagnosed with ALL at a younger age and was associated with central obesity and insulin resistance, which may contribute to adverse outcomes later in life.
Factors influencing health professionals' management of tracheal intubation in oral and maxillofacial malignancies patients after surgery: A qualitative study
Authors: Xu Zhixia , Zou Qinhan , Yang Yuelai , Gu Fen 
Published: November 2024

Abstract

Background
Tracheal intubation is significant for patients with Oral and maxillofacial malignancies (OMMs) after surgery. Despite the development of practice guidelines and training programs, the current management of tracheal intubation by healthcare professionals (HCPs) is inadequate. This study aimed to explore factors that hinder HCPs in managing the tracheal intubation of patients with OMMs after surgery in the intensive care unit (ICU).
Methods
Semi-structured interviews were conducted with 12 experienced HCPs in three clinical units at a tertiary hospital in Shanghai, China, from February to May 2024. Purposive sampling was used. The data were organized and analyzed using NVivo 12.0 software and Braun and Clarke's reflective thematic analysis.
Results
Two themes and seven sub-themes emerged: (1) institutional factors: lack of a risk assessment system for airway obstruction, lack of a tracheal intubation emergency team, preparations for delayed extubation were inconsistent, and inadequate reintubation training for airway obstruction, and (2) individual factors: normativity of airway humidification, reserve of knowledge on the risk of airway obstruction, and attitude about learning about airway obstruction.
Conclusion
HCPs' inadequate management of tracheal intubation in patients with OMMs after surgery is influenced by multiple factors. Designing targeted interventions utilizing these influencing factors will improve HCPs' ability to manage tracheal intubation and ensure the life safety and effective treatment of patients with OMMs following surgery.
