Effects of Supplementary Irrigation with Harvested Rainwater on Growth and Leaf Water Use Efficiency of Glycyrrhiza uralensis Seedling
Authors: Liu Xinghong , Liu Wei , Zhang Wentai , Hu Guiqing
Published: October 2024

Glycyrrhiza uralensis is an important plant in desert ecology, where low rainfall and water scarcity limit its growth. In order to explore harvested rainwater and use for Glycyrrhiza uralensis growth and to reduce water scarcity in Northwest China’s arid area, this study was conducted in April and July of 2023. Five types of slope micro rainwater collection measures, including horizontal terraces, square ridges, and contour ridges, were utilized to monitor rainfall and runoff. Glycyrrhiza uralensis seedlings were utilized as test subjects for supplementary irrigation in pots utilizing the natural drought method. The results show that supplemental irrigation boosts Glycyrrhiza uralensis root growth and water uptake capacity in short-term drought conditions. Irrigation with 42.97 mm enhanced Glycyrrhiza uralensis root length, belowground dry weight, and water use efficiency by 104.5%, 39.54%, and 4.18%. Supplemental irrigation under prolonged drought stress shifted Glycyrrhiza uralensis development from below- to aboveground, resulting in decreased activity of osmotic adjustment material activity in leaves. After 31 days of continuous drought following supplemental irrigation, plant height and aboveground fresh weight increased by 58.16% and 20.03%, respectively, whereas the superoxide dismutase activity was reduced by 63.16% in the 42.97 mm irrigated treatment. Furthermore, under short-term drought stress following supplemental irrigation, leaf water use efficiency was primarily influenced by osmoregulatory substances and plant growth characteristics. Under long-term drought stress, it was influenced by osmoregulatory substances and photosynthetic properties. This research is critical for preventing soil erosion and restoring grassland ecological health in the Ili River Valley.

Published: October 2024

The dam break flood is one of the potential causes of catastrophic events in cascade hydropower hub groups. Investigating the movement patterns of dam break flooding among reservoir groups under different dam break speeds is crucial for flood prevention and emergency response. In this study, the evolution characteristics of dam break floods were investigated in a cascading reservoir system, focusing on different break speeds of the upstream dam. The results indicate that the dam break speed determines the concavity or convexity of the water level curve changes in the upstream reservoir. Accordingly, dam breaks are classified into three modes: instant dam break, fast dam break, and slow dam break. An approximate critical speed has been identified to differentiate between the fast dam break and slow dam break. Further investigation into the evolution patterns of dam break floods in downstream reservoirs under different break modes was conducted. Correspondingly, the flood peak discharge and peak arrival time of the dam break floods vary differently with break speed under different break modes. Finally, a theoretical analysis for the flood peak discharge at the dam site during gradual dam break at a certain speed was established, which is able to predict the over-dam flood peak discharge in fast and slow dam break modes. This study is based on a combination of laboratory flume experiments and three-dimensional numerical simulations. This study has theoretical significance for the reinforcement of public infrastructure safety and the prevention of natural disasters.

Published: October 2024

Based on 40 years of routine water quality monitoring data from Shenzhen Bay and special intensive monitoring since 2021, we analysed the spatiotemporal variations in nitrogen and phosphorus pollution. The results indicate serious levels of nitrogen and phosphorus pollution in Shenzhen Bay. Although recent trends show a decline in concentrations of inorganic nitrogen and reactive phosphate—with the annual average concentration of inorganic nitrogen dropping below 1.0 mg/L since 2020 and reactive phosphate levels near the bay mouth decreasing to approximately 0.020 mg/L—the overall water quality still does not meet China’s Class IV seawater quality standards. Additionally, water quality is poorer during the rainy season, with the average summer concentration of inorganic nitrogen being over 25% higher than in spring and autumn. The water quality is primarily influenced by land-sourced pollutants and tidal effects, generally, with the concentration of DIN and DIP decreased from the estuary of the Shenzhen River, the main seagoing river, to the bay mouth. Near the river’s mouth, concentrations of inorganic nitrogen and reactive phosphate are approximately six and four times higher, respectively, than those near the bay mouth. Due to current emission standards and sewage disposal methods, the proportion of nitrate nitrogen in DIN has significantly increased, exceeding 80% since 2020. To improve the water quality of Shenzhen Bay and to reduce pollution inputs, coordinated land and marine development activities are recommended.
Drought-Induced Agricultural and Food Security Challenges in the Baribo Basin, Cambodia
Authors: Visessri Supattra , Heng Sokchhay
Published: October 2024

Rice production within the Tonle Sap basin is a critical driver of economic and social development in Cambodia. This region has been subject to various natural disasters, with increasing attention directed towards drought. This study aims to evaluate the impacts of drought on agriculture and food security through an in-depth case study of the Baribo basin, a sub-basin of the Tonle Sap. The analysis spans the period from 1985 to 2008, a timeframe characterized by relatively high-quality data. Drought assessment was conducted using ground observations and satellite-based products, with the Standardized Precipitation Index (SPI) and Standard Vegetation Index (SVI) employed to assess meteorological and agricultural droughts, respectively. Findings from both the SPI and SVI indicate that drought constitutes a significant natural hazard contributing to food insecurity in the study area. The highest drought intensity (DI) and drought severity (DS) were recorded during the 1993–1994 period, while the most prolonged drought duration (DD) was observed from 2002 to 2006. The year 2004 witnessed the most severe impact on rice production, with approximately 46% of the total cultivated area affected. The analysis further reveals a strong correlation between the drought duration and the extent of rice cultivation affected, as well as the overall food security in the Tonle Sap basin.

Published: October 2024

Rock permeability, an important factor in subsurface fluid migration, can be influenced by microcracks and chemical weathering due to water–rock interactions. Understanding the relationship between permeability, chemical weathering, and microcracks is crucial for assessing fluid flow in rocks. This study focuses on the hydrogeological characteristics of granite and gneiss, potential host rocks for high-level radioactive waste disposal in South Korea. Samples were analyzed for permeability, porosity, P-wave velocity, and chemical weathering indices. Regression analysis revealed a weak correlation between permeability and both porosity and rock density, while an inverse correlation was observed between permeability and chemical weathering indices. Interestingly, some samples showed low permeability (10−21 to 10−22 m2) despite high weathering, while others showed high permeability (10−18 to 10−19 m2) despite low weathering. SEM-EDS analysis indicated the presence of microcracks within the rocks or the filling of these cracks with secondary minerals. The findings suggest that chemical weathering generally increases pore size and porosity, but actual permeability can vary depending on the presence and connectivity of microcracks and the extent to which they are filled with secondary minerals. Therefore, both chemical weathering and microcrack connectivity must be considered when evaluating the hydrogeological characteristics of crystalline rocks.

Published: October 2024

The Santiago-Guadalajara River Basin (SGRB), located in western Mexico, is one of the most polluted rivers in the country. A pesticide monitoring program was carried out from January 2022 to September 2022, during which time water samples collected at 25 sites in the main stem and tributaries revealed the presence of 13 of the 24 pesticides analyzed, including α-BHC, β-BHC, γ-BHC (Lindane), γ-Chlordane, Hexachlorobenzene, Heptachlor, Aldrin, α-Endosulfan, DDT, -4,4, Methoxychlor, Chlorpyrifos-methyl, Endosulfan sulfate, and Dicofol. A high level of correlation was found between the identified pesticides, which could mean that several of these pesticides reached a stable level within the monitored water bodies. Most of the identified pesticides are classified as high environmental risk according to the Stockholm Convention because of their persistence and high degree of toxicity to the environment and human health. A Pesticide Toxicity Index (PTI) was applied to identify the streams considered to be of concern due to the presence of pesticides exceeding the threshold limits established by national and international guidelines. Performing a calculation for the entire Santiago-Guadalajara River Basin, the PTI reached a value of 0.833, which, according to the criteria of this method, classifies it as a “Moderate” level of risk for aquatic life. Increased regulatory and surveillance measures by state and federal authorities are required to prevent the use of these pesticides, which have been restricted globally.
Improvement of Salt Leaching Efficiency and Water Content of Soil Through Irrigation with Electro-Magnetized Saline Water
Authors: Bouhlel Mohamed , Khaskhoussy Khawla , Hachicha Mohamed
Published: October 2024

While the advantageous effects of using magnetic and electromagnetic treatment (ET) of brackish and saline waters on soil salinity reduction in the root zone were largely reported, more studies are needed to answer questions about the soil salt leaching efficiency and the effect of the duration of the exposure to ET. For this aim, pot experiments were conducted using an Aqua-4DR physical water treatment device. The first experiment included two trials. The first trial considered five concentrations: C0:1.0; C1:4.5; C2:9; C3:13.5; and C4:18 dS m−1. The results revealed that the volume and the salt concentrations of the drained waters were significantly higher under irrigation with ET saline waters than those provided by untreated waters. The drained fraction of water varied from 20 to 26% under irrigation with untreated water and increased from 33 to 56% under irrigation with electro-magnetized water, indicating an improvement in the salt leaching. The second trial was carried out with different irrigation doses. The results showed that the higher the dose, the more obvious and significant the ET effect. The different treatment durations of water exposure revealed that the volume and salinity of drained water significantly increase as the ET duration increases. An increase in the ET duration also induces an increase in the soil water content of around 2.5%. Based on the experimental findings, we may conclude that the ET of saline water can reduce the adverse effect of salinity on the top soil, but these leached salts are carried away in depth and there is no concentration limit of water to the effect of the ET.
Bottled or Tap Water? Factors Explaining Consumption and Measures to Promote Tap Water
Authors: Zvěřinová Iva , Ščasný Milan , Otáhal Jan
Published: October 2024

The production and consumption of plastic bottled water have several negative environmental impacts worldwide. To identify the barriers and motivations for drinking tap and bottled water, we conducted a nationally representative questionnaire survey among 3411 respondents in the Czech Republic in 2022. People aged 18–34 are moderate consumers of bottled water and very frequent consumers of tap water. Bottled water consumption tends to be less frequent among people with a higher education, while tap water consumption is less frequent among people with lower incomes. The most important factors that explain the frequency of drinking bottled and tap water are taste perception, health concerns and habit. Health concerns about tap water and the unpleasant taste of tap water increase the consumption of bottled water. People with a strong habit of drinking tap water are less likely to consume bottled water. The constructs from the theory of planned behaviour were statistically significant. The results can guide decision-makers in promoting tap water to consumers. To encourage tap water drinking, we suggest measures to increase the availability of tap water in public places in conjunction with campaigns targeting the taste and health perception, as well as the habit, of drinking tap water.

Published: October 2024

This paper analyses the names of village parts in the onomastic material recorded in the inquiry notebooks for ALR II and published by Doina Grecu, Ion Mării and Rodica Orza, being an attempt at their classification according to different linguistic criteria. Under the generic name of parts of the village, both communication routes (roads, streets, paths) and residential areas on the territory of the village (around the centre or on the outskirts of the village, clusters of isolated houses, hamlets) are identified. From the point of view of their origin, the names of village parts collected during ALR II investigation can be classified into three categories: 1. names based on a group name; 2. names based on other topical names; 3. names whose structure includes orientation landmarks. The names of com­munication routes are treated in a different category, because they often contain, in addition to an anthroponym, group names or toponyms, some orientation markers: downhill/from below, uphill/from above, etc. The second part of the article approaches the toponymic material according to the structure of the toponyms.

Authors: Souza Bruno de Oliveira , Paz Eulália Vitória Nascimento da , Lima Paulina Pereira de , Silva Jones Cunha da
Published: October 2024

O texto aborda os direitos e garantias fundamentais, que são essenciais para a ordem jurídica constitucional e inalienáveis aos indivíduos. Enquadrados no paradigma do constitucionalismo, esses direitos são cruciais na organização política e social de uma sociedade. A Constituição brasileira assegura sua aplicação imediata, evitando a ineficácia diante da omissão legislativa, com base na dignidade da pessoa humana. A análise histórica, como a experiência da Alemanha nazista, reforça a importância de proteger esses direitos contra a arbitrariedade. Além disso, o estudo discute os desafios da eficácia das normas constitucionais que, por vezes, necessitam de regulamentação para serem plenamente efetivas, como o direito à privacidade. A pesquisa enfatiza que, apesar de serem essenciais para prevenir abusos de poder e promover a justiça, alguns direitos ainda demandam uma regulamentação complementar para serem devidamente aplicados.

Published: October 2024

Background and aims: Nurses are exposed to a variety of stresses that can cause mental health problems and lead to burnout. However, the severity of these problems in nurses also depends on their resilience. Therefore, this study aimed to investigate the correlation between nurses’ resilience and burnout levels during the COVID-19 pandemic. Methods: In this cross-sectional study, 328 nurses from four hospitals in Hilla city, Babylon province, Iraq, were enrolled in August and September 2021. Data collection tools included a demographic information form, the Anxiety, Stress, and Depression Scale (DASS-21), the Connor-Davidson Resilience Scale (CD-RISC), and the Copenhagen Burnout Inventory (CBI). The collected data were analyzed using SPSS-16 software at a significance level of 0.05. Results: The mean resilience score among nurses was 68.05±17.04, and the majority (77.4%) had a moderate level of burnout. There was a significant and inverse correlation between depression (r=-0.27, P<0.001), anxiety (r=-0.12, P<0.001), stress (r=-0.180, P<0.001), and resilience of nurses. Also, there was a significant correlation between nurses’ burnout and resilience. Conclusion: Enhancing nurses’ resilience is crucial for improving their mental health and sustaining healthcare quality during crises. Future studies should explore interventions to boost resilience and examine their long-term effects on burnout and mental health. These findings help develop strategies to support nurses, ensuring better healthcare outcomes during challenging times.

Background and aims: Procrastination is a common issue among students and is often linked to a lack of motivation. The main aim of this study was to evaluate the relationship between procrastination, motivation, and academic achievement of midwifery and nursing students. Methods: In this cross-sectional study in 2023, 258 participants were enrolled, and data were collected by online distribution of three primary questionnaires, including the Procrastination Assessment Scale for Students and Hermans’ Questionnaire Measure of Achievement Motivation, along with a customized questionnaire. The chi-squared test was used for statistical analysis. Results: The mean score of achievement motivation among participants with academic achievement was considerably higher (P=0.006). When adjusted for confounding factors, female participants were found to have a higher likelihood of academic achievement (4-fold) than male counterparts. A significant inverse correlation was found between academic motivation and procrastination (r=−0.492, P<0.001). We also noted a significant association between interest in the field of study and achievement motivation (P=0.039). Conclusion: The study showed that academic achievement and motivation significantly influence one another, and strategies aimed at improving motivation can lead to a higher incidence of academic achievement and, thus, academic performance.

Published: October 2024

Background and aims: Therapeutic procedures, including the placement of intravenous catheters, are among the most common sources of pain for children. Various methods exist to reduce pain during venipuncture in children, including non-pharmacological methods, but there is no consensus on the most effective approach. The aim of this study is to evaluate the effectiveness of non-pharmacological methods on pain intensity during venipuncture in children. Methods: This systematic review and meta-analysis were conducted based on English and Persian articles published in the databases of PubMed, Web of Science, Scopus, CINAHL, ScienceDirect, Google Scholar, Irandoc, Iranmedex, SID, and Magiran between 1911 and 2023, using the keywords Venipuncture, Children, Pain, and their MeSH equivalents in all possible combinations. Data analysis was performed using STATA 11 software. Results: Out of 6963 studies obtained from the initial search, 17 eligible articles were included in the meta-analysis. The results of the random effects model showed that among non-pharmacological methods, the pain score of children in the distraction intervention group was 1.72 points lower than that of children in the comparison group, placing it in the strong effectiveness category. Furthermore, distraction interventions were found to be more effective in children under 8.5 years old, with bubble-blowing interventions proving to be the most effective among all. The findings in other groups also showed that acupressure and educational booklet reading interventions performed by the child on a teddy bear were more effective than distraction interventions. Conclusion: Non-pharmacological interventions seem to be an easy, accessible, and cost-effective method for nurses to manage pain associated with venipuncture according to children’s age.

Published: October 2024

A persistência do quarto arco aórtico direito (PAAD) é uma afecção que se inicia na fase embrionária através do mal desenvolvimento das estruturas vasculares dos arcos aórticos.  Dentre todas as anomalias dos anéis vasculares, a PAAD é a mais comum, correspondendo a 95% de toda casuística. Costuma ter diagnóstico precoce, em especial no período de desmame e introdução da dieta seca, visto que tal má formação leva a uma constrição esofágica dificultando a passagem do alimento. O diagnóstico é baseado na história clínica, sinais clínicos e exames de imagem, sendo a intervenção cirúrgica o tratamento de eleição. O objetivo do presente trabalho é relatar um caso de PAAD em um cão de 3 meses de idade, macho, beagle, atendido no Hospital Veterinário Universitário da UFRPE, com histórico de regurgitação e emagrecimento. Após exame físico, foram solicitados exames de imagem e o paciente foi diagnosticado com possível persistência do quarto arco aórtico direito. Posteriormente, foram solicitados os exames pré operatórios e realizado o encaminhamento para a cirurgia. O paciente foi submetido a uma toracotomia pelo quarto espaço intercostal esquerdo para identificação, ligadura e transecção do ducto arterioso e dilatação esofágica através de uma sonda de Foley. Após o procedimento, o paciente foi encaminhado para uma unidade de cuidados intensivos veterinários, recebendo alta após 4 dias. O primeiro retorno foi realizado com 15 dias e o paciente apresentava evolução e cicatrização da ferida cirúrgica, recebendo alta médica. Concluindo-se que a cirurgia foi eficaz no tratamento da afecção.

Published: October 2024

Este estudo aprofundou o entendimento do regime hídrico e a perda de solo através dos sedimentos em suspensão em bacia rural com intensa produção agropecuária. Identificou-se que há ocorrências de chuvas significativas anuais de até 2777 mm na bacia hidrológica, sendo que nestes períodos chuvosos (ano de El niño) há intensidade de chuvas mensais significativas que podem alcançar 300% acima da média mensal, provocando fluxos superficiais difusos significantes carreando para o rio elevados volumes de sedimentos, ultrapassando em 50% a média mensal de descarga sólida que é transportada para fora da bacia, apresentando risco de degradação do solo e das águas superficiais que causam alterações na qualidade de água. A Bacia Hidrográfica do Lajeado do Fragosos apresentou vazão média anual na foz de cerca de 1,2 m3.s-1, onde se observa uma forte correlação entre as variáveis de precipitação e descarga líquida, com baixo tempo de concentração, na ordem de 3,8 horas. As informações sobre as características do curso d´água, por meio da curva de permanência, permitiu caracterizar que o comportamento do curso d´água da bacia é um regime pluvial fortemente torrencial perene. A análise da curva de permanência da vazão mostrou que pode ser uma boa ferramenta para avaliar o armazenamento da água do solo e o regime pluvial  de um curso d´água.

Authors: Gudkov Viktor , Sokol Pavel
Published: October 2024

Currently, tracked snowmobile tractor transporters with residential modules operating in the Antarctic region, making transitions to the interior of the continent, have practically exhausted their resource and need to be updated, and the design of well–known serial samples of tracked tractor transporters, mainly dual-use, does not take into account the full range of factors affecting operation in Antarctica, this makes them limited suitable for widespread use in this region. A scientifically based design of a tracked snowmobile tractor transporter for operation in the Antarctic region for long–distance movement inland in conditions of extremely low ambient temperatures and implemented by its design and basic tactical and technical characteristics is presented.

Molecular dynamics study of the effect of composition on elastic properties of silicon oxynitride films
Authors: Miyazaki Sakurako , Sakakima Hiroki , Ogawa Keigo , Izumi Satoshi
Published: October 2024

Understanding the mechanical properties of silicon oxynitride (a-SiON), a key insulating material, is vital for electronic device design and reliability. Though the effects of fabrication conditions on a-SiON have been studied, the underlying relationship between its atomic-scale structure and mechanical properties remains unclear. This study investigates the relationship between elasticity and atomic-scale structures in a-SiON by molecular dynamics simulations with a universal graph neural network interatomic potential. The bulk modulus increases from 49 to 150 GPa with higher N content. N atoms form N2 molecules under O-rich conditions, hindering bulk modulus increase, and form an Si3N4-like network under O-poor conditions, enhancing bulk modulus. Formation energy calculations indicate N2 formation is preferable under O-rich conditions. Meanwhile, under O-poor conditions, Si–N bond formation is preferable, which reinforces a-SiON by increasing bond density. The findings suggest realizing O-poor conditions is crucial for highly elastic insulating films.
Double localized surface plasmon‒enhanced-second-harmonic generation behavior of equilateral triangular aluminum nanoprisms
Authors: Sugita Atsushi , Muroi Kennshin , Tamotsu Sohta
Published: October 2024

This paper presents second-harmonic generation (SHG) behaviors for different-sized equilateral triangular aluminum nanoprisms. These behaviors were observed under the double localized surface plasmon (LSP) resonance condition. The SHG conversion efficiency was substantially enhanced when the excitation and SHG wavelengths were simultaneously tuned to the LSP-resonance wavelengths. The fundamental and higher-order LSP modes could be used to enhance the SHG conversion efficiency. The nonlinear light‒matter interaction associated with the double LSP resonance was numerically analyzed while focusing on the spatial overlap of the near-field distributions between the excitation and SHG wavelengths. The double LSP resonance enhanced SHG behaviors have been realized by using several elegantly designed plasmonic metal nanostructures consisting of multi-elements. Our present study demonstrates this double LSP resonance enhanced SHG behavior from a single, simple-shape triangular aluminum nanoprism.
