Published: August 2024

Wheat dwarf virus (WDV, genus Mastrevirus, family Geminiviridae) is one of the causal agents of wheat viral disease, which severely impacts wheat production in most wheat-growing regions in the world. Currently, there is little information about natural resistance against WDV in common wheat germplasms. CRISPR/Cas9 technology is being utilized to manufacture transgenic plants resistant to different diseases. In the present study, we used the CRISPR/Cas9 system targeting overlapping regions of coat protein (CP) and movement protein (MP) (referred to as CP/MP) or large intergenic region (LIR) in the wheat variety ‘Fielder’ to develop resistance against WDV. WDV-inoculated T1 progenies expressing Cas9 and sgRNA for CP/MP and LIR showed complete resistance against WDV and no accumulation of viral DNA compared with control plants. Mutation analysis revealed that the CP/MP and LIR targeting sites have small indels in the corresponding Cas9-positive plants. Additionally, virus inhibition and indel mutations occurred in T2 homozygous lines. Together, our work gives efficient results of the engineering of CRISPR/Cas9-mediated WDV resistance in common wheat plants, and the specific sgRNAs identified in this study can be extended to utilize the CRISPR/Cas9 system to confer resistance to WDV in other cereal crops such as barley, oats, and rye.
Spectroscopic Indices Reveal Spatiotemporal Variations of Dissolved Organic Matter in Subtropical Karst Cave Drip Water
Authors: Dong Hui , Zhou Zhongfa
Published: August 2024

The migration and transformation of dissolved organic matter (DOM) in highly heterogeneous and permeable karst aquifers are of great significance to the regional carbon cycle but are rarely explored, especially in response to extreme climate events. In this study, we utilized spectroscopic indices to investigate variations in DOM concentration, composition, and origin in Mahuang Cave, Southwest China, from August 2020 to October 2022. The findings indicate that meteorological conditions, hydrological pathways, and in–situ metabolism primarily control DOM dynamics in karst cave drip water. However, due to the complex cave fractures and stratigraphy, the DOM composition at the four monitoring sites—classified into slow and fast seepage—showed different responses to meteorological events. Therefore, surface reworking must be fully considered when assessing the environmental information recorded by cave sediments.

Published: August 2024

The hydrochemical characteristics of watersheds are influenced by many factors, with chemical weathering and human activities exerting the most substantial influence. Performing a quantitative evaluation of the factors contributing to the chemical weathering of rocks is of significant scientific importance. This research zeroes in on the Qingtang River basin to elaborate on the hydrochemical characteristic, explore the origins of ions, and quantify the influence of anthropogenic discharges amidst cation interferences, thus improving the accuracy of chemical weathering rate estimations. The samples encompassed surface water, groundwater, and water from dripping in karst caves. The findings indicate that human-induced alterations significantly influence hydrogeochemical dynamics, although chemical weathering of rocks in their natural state is the controlling factor. The mean contributions of cations from atmospheric deposition, human inputs, carbonate weathering, and silicate weathering were 17.56%, 21.05%, 51.77%, and 9.54%, respectively. The chemical weathering rate for carbonate rocks was 62.4 t·km−2·a−1, which increased by 27.87% due to the influence of exogenous acids. The anthropogenic impact is predominantly evident in two aspects: (1) the alteration of hydrochemical processes within the watershed through direct input of ions, and (2) the acceleration of rock weathering rates in the watershed due to the exogenous acids.

Published: August 2024

Holistic environmental flow assessment includes evaluation of chemical, biological, hydrological, and morphological changes predicted from disrupting a river flow regime. Using available water chemistry together with biological and hydrological surveys, we report and assess environmental flows of the Alijanchay River, an important tributary of the Kura River, at four monitoring stations located in Azerbaijan. The river’s natural flow regime has changed significantly due to the irrigation activities in the middle and lower reaches and further development is planned through construction of new reservoirs. Our methodology is based on the results of morphological, hydrological, and hydrobiological observations and analysis of the physical and chemical parameters of the river. Environmental flow was evaluated by six hydrological methods proposed in the literature, and a comparative analysis shows that its value has increased from 13.6 to 27.1% of the annual flow volume, consistent with increased pressure on this important surface water supply. Water Quality Indices (WQI) further show seasonal changes of water quality in this important water supply, impacting sustainable uses for drinking and agriculture. Parameters most affected by seasonal changes are turbidity, suspended solids, and dissolved oxygen. Further degradation of environmental flows of this important watershed in Azerbaijan are likely from the planned development. A more comprehensive holistic ecological flow can help support a sustainable plan for use of Alijanchay River basin water reserves, and, if resources are provided for other basins, can support development elsewhere.

Published: August 2024

Establishing appropriate boundary conditions is essential for developing high-accuracy hydrodynamic models. However, this task is particularly challenging in topographically varying urban domains without monotonous slopes due to insufficient boundary information. This study investigates five different boundary conditions and establishes modeling practices of boundary conditions in pluvial urban flood modeling. A numerical test model within the city of Berlin is used, employing the 2D hydrodynamic finite element module of the open-source TELEMAC system. It performs unsteady simulations with nodal rainfall inputs for various precipitation scenarios, excluding infiltration. The results demonstrate that the suitability of boundary conditions is critically dependent on the surrounding topography. For boundary segments with a positive slope, a stage–discharge curve is found to outperform the other boundary conditions investigated in this study. Conversely, for segments with a negative slope, a closed wall boundary condition appears clearly preferable. Additionally, a drainage reservoir boundary condition performs effectively for more complex boundary segments but necessitates extensive preprocessing. Based on these insights, simulations were repeated with segment-tailored boundary conditions. The results indicate that this combined model outperforms the global application of each individual model.
Improvement of Removal Rates for Iron and Manganese in Groundwater Using Dual-Media Filters Filled with Manganese-Oxide-Coated Sand and Ceramic in Nepal

Published: August 2024

Iron and manganese in groundwater impair the quality of drinking water; however, the rates of iron and manganese removal with conventional aeration and rapid sand filtration (RSF) processes vary extensively. Five full-scale aeration–RSF processes in Nepal also showed varying efficiencies of iron and manganese removal; while the iron concentration was below the national standard (0.30 mg/L) in 31 out of the 37 treated waters, the manganese concentration was higher than the standard (0.20 mg/L) in all of the treated waters. Re-aeration and stirring of the treated water did not oxidize soluble manganese, and this caused the poor removal rates for manganese. Bench-scale dual-media filters comprising anthracite on top of sand/ceramic layers with dosages of poly aluminum chloride and chlorine worked well by removing coagulated iron in the anthracite layer and then removing manganese in the sand/ceramic layers. A manganese-oxide-coated ceramic filter provided the highest manganese removal from 1.10 mg/L to <0.01 mg/L, followed by manganese-oxide-coated sand and quartz sand. Increasing the pH from 7.5 to 9.0 stabilized the manganese removal. Therefore, we propose a re-design of the present treatment processes and the selection of suitable filter media for better removal of iron and manganese.

Published: August 2024

The fluctuation of the tide is closely related to the production and life of people in coastal areas, and the change in the tide level will have a significant impact on the safety of infrastructure, ship travel, ecological environment, and other issues. Therefore, it is of great significance to analyze, study, and forecast the change in tide level. Aiming at the complex characteristics of nonlinearity, time-varying dynamics, and uncertainty generated by celestial bodies’ movements and influenced by geographical as well as hydrometeorological factors, this paper proposes a combined model based on variational mode decomposition (VMD) and long short-term memory neural networks (LSTM). A tidal level prediction procedure is proposed by combining the harmonic analysis method with a neural network and takes the point tide data of Luchao Port from 2021 to 2022 as the applied data. First, the VMD algorithm decomposes the tidal level data into model components. Then, the LSTM model is used to predict each component. Finally, the predicted value of each component is superposed to obtain the final prediction result. Standard evaluation indexes were used to analyze the performance of the proposed model. The model’s RMSE, MAE, MAPE, and R2 were 0.0385, 0.0267, 5.8327, and 99.91%, respectively, superior to other compared models (BP, SVM, and LSTM). This study can provide a reference for tidal level prediction. These results show that the VMD-LSTM model is an effective and reliable tidal level prediction tool with considerable potential in offshore engineering and maritime management.

Published: August 2024

Human activities have resulted in the eutrophication of rivers, leading to heightened concerns regarding the occurrence of filamentous algal blooms. With the increasing utilization of rivers by humans, the occurrence of these nuisance filamentous algae is expected to increase in frequency in the future. Blooms primarily occur due to energy congestion at the trophic level of primary producers, resulting from inefficient energy flow in both the bottom-up and top-down pathways. To investigate the mechanism underlying the outbreak of filamentous algae, two streams in the southern Taihang catchment with different nutrient conditions were selected for this study. The objective of this study was to understand the effects of nutrient levels and other potential factors on the distribution and succession of filamentous algae. Our findings revealed a positive correlation between nutrient conditions and the biomass of filamentous algae. Cladophora and Spirogyra were identified as the dominant species among filamentous algae, each exhibiting unique distribution patterns in the two streams. Spirogyra thrived predominantly in the Baligou stream, where lower nutrient levels and warmer temperatures prevailed. In contrast, Cladophora flourished in the nutrient-rich Nanping stream at colder temperatures. Results from the generalized linear model indicated that the biomass of Cladophora was influenced by nutrient concentration, water depth, water temperature, and macrobenthic biomass. The biomass of Spirogyra, on the other hand, was primarily determined by water temperature, nutrient concentrations, water depth, and velocity. The positive correlation between Cladophora and macrobenthos revealed a possible mutually beneficial relationship, suggesting that macrobenthos may promote the growth of Cladophora by inhibiting periphytic diatoms. In return, the macrobenthos benefit from a secure refuge and an environment conducive to foraging and reproduction. This study suggested that to alleviate energy flow congestion in the benthic food chain, it is advisable to address this issue by either reducing nutrient loadings in rivers or enhancing the presence of benthivorous fishes in streams.
Evaluation of a Coupled CFD and Multi-Body Motion Model for Ice-Structure Interaction Simulation

Published: August 2024

The interaction of water flow, ice, and structures is common in fluvial ice processes, particularly around Ice Control Structures (ICSs) that are used to manage and prevent ice jam floods. To evaluate the effectiveness of ICSs, it is essential to understand the complex interaction between water flow, ice and the structure. Numerical modeling is a valuable tool that can facilitate such understanding. Until now, classical Eulerian mesh-based methods have not been evaluated for the simulation of ice interaction with ICS. In this paper we evaluate the capability, accuracy, and efficiency of a coupled Computational Fluid Dynamic (CFD) and multi-body motion numerical model, based on the mesh-based FLOW-3D V.2023 R1 software for simulation of ice-structure interactions in several benchmark cases. The model’s performance was compared with results from meshless-based models (performed by others) for the same laboratory test cases that were used as a reference for the comparison. To this end, simulation results from a range of dam break laboratory experiments were analyzed, encompassing varying numbers of floating objects with distinct characteristics, both in the presence and absence of ICS, and under different downstream water levels. The results show that the overall accuracy of the FLOW-3D model under various experimental conditions resulted in a RMSE of 0.0534 as opposed to an overall RMSE of 0.0599 for the meshless methods. Instabilities were observed in the FLOW-3D model for more complex phenomena that involve open boundaries and a larger number of blocks. Although the FLOW-3D model exhibited a similar computational time to the GPU-accelerated meshless-based models, constraints on the processors speed and the number of cores available for use by the processors could limit the computational time.
Functional and Microbiological Responses of Iron–Carbon Galvanic Cell-Supported Autotrophic Denitrification to Organic Carbon Variation and Dissolved Oxygen Shaking

Published: August 2024

Iron–carbon galvanic-cell-supported autotrophic denitrification (IC-ADN) is a burgeoning efficient and cost-effective process for low-carbon wastewater treatment. This study revealed the influence of organic carbon (OC) and dissolved oxygen (DO) on IC-ADN in terms of functional and microbiological characteristics. The nitrogen removal efficiency increased to 91.6% and 94.7% with partial organic carbon source addition to COD/TN of 1 and 3, respectively. The results of 16S rRNA high-throughput sequencing with nirS and cbbL clone libraries showed that Thiobacillus was the predominant autotrophic denitrifying bacteria (ADB) in the micro-electrolysis-based autotrophic denitrification, which obtained nitrogen removal efficiency of 80.9% after 96 h. The ADBs shifted gradually to heterotrophic denitrifying bacteria Thauera with increasing COD/TN ratio. DO concentration of 0.8 rarely affected the denitrification efficiency and the denitrifying communities. When the DO concentration increased to 2.8 mg/L, the nitrogen removal efficiency decreased to 69.1%. These results demonstrated that autotrophic denitrification was notably affected by COD/TN and high DO concentration, which could be used to acquire optimum conditions for nitrogen removal. These results provided an in-depth understanding of the influential factors for galvanic-cell-based denitrification and helped us construct a stable and highly efficient treatment process for insufficient carbon source wastewater.

Sepsis is the most lethal and expensive condition treated in intensive care units. Sepsis survivors frequently suffer long-term cognitive impairment, which has been linked to the breakdown of the blood–brain barrier (BBB) during a sepsis-associated “cytokine storm”. Because animal models poorly recapitulate sepsis pathophysiology, human models are needed to understand sepsis-associated brain injury and to develop novel therapeutic strategies. With the concurrent emergence of tissue chip technologies and the maturation of protocols for human induced pluripotent stem cell (hiPSC), we can now develop advanced in vitro models of the human BBB and immune system to understand the relationship between systemic inflammation and brain injury. Here, we present a BBB model of the primary barrier developed on the μSiM (microphysiological system enabled by an ultrathin silicon nanomembrane) tissue chip platform. The model features isogenically matched hiPSC-derived extended endothelial culture method brain microvascular endothelial cell-like cells (EECM-BMEC-like cells) and brain pericyte-like cells (BPLCs) in a back-to-back coculture separated by the ultrathin (100 nm) membrane. Both endothelial monocultures and cocultures with pericytes responded to sepsis-like stimuli, with increased small-molecule permeability, although no differences were detected between culture conditions. Conversely, BPLC coculture reduced the number of neutrophils that crossed the EECM-BMEC-like cell monolayer under sepsis-like stimulation. Interestingly, this barrier protection was not seen when the stimulus originated from the tissue side. Our studies are consistent with the reported role for pericytes in regulating leukocyte trafficking during sepsis but indicate that EECM-BMEC-like cells alone are sufficient to maintain the restrictive small-molecule permeability of the BBB.

DNA damage, oxidative stress, and inflammation. However, to date, no effective drug treatment has been found. Even the potential antidotes could not effectively penetrate the top layer of the skin to exert their effects due to the skin barrier. To address this problem, an innovative transdermal drug delivery strategy based on aspirin microneedles was proposed. The classic medicine aspirin was first discovered not only to reduce inflammation and oxidative stress but also to promote DNA repair and reduce DNA damage. The aspirin microneedles directly delivered the drug to the damaged area, released aspirin through the skin barrier, and exhibited good biocompatibility. These findings indicate that aspirin microneedles have great potential for promoting wound healing and broad application prospects.

It seems relevant to analyze the employer’s role the in supporting the state's pro-natalist policy in the process of searching for effective tools to achieve the strategic goals of the internal policy of the Russian Federation aimed at saving the population and developing human potential. The article substantiates the importance and relevance of the support measures provided by the employer to employees and their families. The current principles and directions of corporate demographic policy is considered. The importance of corporate demographic policy for educational institutions is substantiated. One of the approaches to such a policy implementation is proposed to consider the inclusion of employee support measures into the organizational Collective Agreement. The analysis of the Collective Agreement of the educational institution - the Federal State Budgetary Educational Institution "NGUEU" was carried out as a case study. The main directions of the corporate demographic policy implemented by the educational institution are identified. These include ensuring the employees’ life and health protection; decent remuneration for work; respect for family responsibilities of employees with children; an effective system of interaction with employees as the main company’s stakeholders. Assumptions are made about the potential impact of these measures on the achievement of state pro-natalist goals and employer’s key goals related to the human capital formation.
Coincidentia oppositorum and its ontological and logical foundations, at Mircea Eliade
Authors: Silion Bogdan
Published: August 2024

Mircea Eliade’s methodology has been often criticized for the excess of making an ontology of the interpretations of the religious phenomena. At its essence, the Romanian theorist infers that reality is sacred, even if it is perceived, through the eyes of the man “fallen into history”, as being profane. Interpreting this permanent dialectics between the sacred and profane, the professor from Chicago imposes a model of knowledge of religious facts which relies on special logics, in which the relations between opposite terms are no longer seen as antithetical but rather as synthetic. Such logics, obviously Aristotelian, rather close to the Vedantic mystics or negative theology, has the Cusanian concept of coincidentia oppositorum as a starting point. In the thinking of the Romanian historian of religions, the coincidence of the contraries is an all plans functional concept. From an ontological point of view, it is found in the internal cloth of the world, as a “breach at ontological level”, for the archaic man, as well as a structure of the sacred. The sacred-profane dialectic is the “domain” prone to develop this concept, at least from the perspective of the union of the contraries logics. Eliade’s hermeneutics also lie under the sign of the unity of contraries. The interpretation of the symbolic facts, to the extent in which it is complete, is more a technique of the real, which aims at creating a new structure of awareness, similar to the one of the yogi found in the supreme stasis or of “the freeman alive” (jīvanmūkta). Thus, the coincidentia oppositorum develops as a paradox of non-conditioning, of freedom, of a new consciousness, which transcends the common logical categories. This is why the language which describes such a “state” is an unusual one, paradoxical and enstatic, resembling the reality described. Mircea Eliade is the promoter of a new logical eon, of symbolical type, which is meant to eventually be a new humanism. As it has an internal logic, a goal, specific attributes and concepts, Mircea Eliade’s conception about the sacred analysed through the unity of the contraries may be considered consistent and it may be imposed as aWeltanschauung of the author.

Published: August 2024

This paper examines how the sanitary separation of the St. George Island from the rest of the Russian Empire influenced the development of the town Sulina, the main settlement established on this island, and the creation of a distinct territorial identity. To this end, I have corroborated archival documentary sources from the archival fund ‘Chancellery of the Governor of Bessarabia’, held at the National Archive of the Republic of Moldova, with other types of narrative accounts, be they authored by travelers, sailors, merchants or soldiers who visited Sulina during that period. The paper will thus determine how the sanitary isolation of the St. George Island manifested itself, then it will analyse the lucrative opportunities that attracted new inhabitants to Sulina and examine how, despite harsh living conditions, Sulina came to be regarded as an ‘American Eden’.

Berdasarkan hasil penelitian dan pembahasan dapat diketahui bahwa hapusnya hak milik atas tanah yang dijadikan sebagai objek jaminan hak tanggungan maka Hak tanggungan juga akan ikut hapus.
