Application of the New Iterative Method (NIM) to the Generalized Burgers–Huxley Equation
Authors: Batiha Belal , Ghanim Firas , Batiha Khaled
Published: March 2023

In this paper, we propose the new iterative method (NIM) for solving the generalized Burgers–Huxley equation. NIM provides an approximate solution without the need for discretization and is based on a set of iterative equations. We compared the NIM with other established methods, such as Variational Iteration Method (VIM), Adomian Decomposition Method (ADM), and the exact solution, and found that it is efficient and easy to use. NIM has the advantage of quick convergence, easy implementation, and handling of a wide range of initial conditions. The comparison of the present symmetrical results with the existing literature is satisfactory.
Molecular Mechanisms of Antiviral Agents against Dengue Virus
Authors: Lee Michelle Felicia , Wu Yuan Seng , Poh Chit Laa
Published: March 2023

Dengue is a major global health threat causing 390 million dengue infections and 25,000 deaths annually. The lack of efficacy of the licensed Dengvaxia vaccine and the absence of a clinically approved antiviral against dengue virus (DENV) drive the urgent demand for the development of novel anti-DENV therapeutics. Various antiviral agents have been developed and investigated for their anti-DENV activities. This review discusses the mechanisms of action employed by various antiviral agents against DENV. The development of host-directed antivirals targeting host receptors and direct-acting antivirals targeting DENV structural and non-structural proteins are reviewed. In addition, the development of antivirals that target different stages during post-infection such as viral replication, viral maturation, and viral assembly are reviewed. Antiviral agents designed based on these molecular mechanisms of action could lead to the discovery and development of novel anti-DENV therapeutics for the treatment of dengue infections. Evaluations of combinations of antiviral drugs with different mechanisms of action could also lead to the development of synergistic drug combinations for the treatment of dengue at any stage of the infection.

Published: March 2023

Introduction: Eastern equine encephalitis virus (EEEV) and Venezuelan equine encephalitis virus (VEEV) viruses are zoonotic pathogens affecting humans, particularly equines. These neuroarboviruses compromise the central nervous system and can be fatal in different hosts. Both have significantly influenced Colombia; however, few studies analyse its behaviour, and none develop maps using geographic information systems to characterise it. Objective: To describe the temporal-spatial distribution of those viruses in Colombia between 2008 and 2019. Methods: Retrospective cross-sectional descriptive study, based on weekly reports by municipalities of the ICA, of the surveillance of both arboviruses in equines, in Colombia, from 2008 to 2019. The data were converted into databases in Microsoft Access 365®, and multiple epidemiological maps were generated with the Kosmo RC1®3.0 software coupled to shape files of all municipalities in the country. Results: In the study period, 96 cases of EEE and 70 of VEE were reported, with 58% of EEE cases occurring in 2016 and 20% of EEV cases in 2013. The most affected municipalities for EEE corresponded to the department of Casanare: Yopal (20), Aguazul (16), and Tauramena (10). In total, 40 municipalities in the country reported ≥1 case of EEE. Conclusions: The maps allow a quick appreciation of groups of neighbouring municipalities in different departments (1° political division) and regions of the country affected by those viruses, which helps consider the expansion of the disease associated with mobility and transport of equines between other municipalities, also including international borders, such as is the case with Venezuela. In that country, especially for EEV, municipalities in the department of Cesar are bordering and at risk for that arboviral infection. there is a high risk of equine encephalitis outbreaks, especially for VEE. This poses a risk also, for municipalities in the department of Cesar, bordering with Venezuela.
Pregnancy Is Associated with Impaired Transcription of Human Endogenous Retroviruses and of TRIM28 and SETDB1, Particularly in Mothers Affected by Multiple Sclerosis

Published: March 2023

Accumulating evidence highlights the pathogenetic role of human endogenous retroviruses (HERVs) in eliciting and maintaining multiple sclerosis (MS). Epigenetic mechanisms, such as those regulated by TRIM 28 and SETDB1, are implicated in HERV activation and in neuroinflammatory disorders, including MS. Pregnancy markedly improves the course of MS, but no study explored the expressions of HERVs and of TRIM28 and SETDB1 during gestation. Using a polymerase chain reaction real-time Taqman amplification assay, we assessed and compared the transcriptional levels of pol genes of HERV-H, HERV-K, HERV-W; of env genes of Syncytin (SYN)1, SYN2, and multiple sclerosis associated retrovirus (MSRV); and of TRIM28 and SETDB1 in peripheral blood and placenta from 20 mothers affected by MS; from 27 healthy mothers, in cord blood from their neonates; and in blood from healthy women of child-bearing age. The HERV mRNA levels were significantly lower in pregnant than in nonpregnant women. Expressions of all HERVs were downregulated in the chorion and in the decidua basalis of MS mothers compared to healthy mothers. The former also showed lower mRNA levels of HERV-K-pol and of SYN1, SYN2, and MSRV in peripheral blood. Significantly lower expressions of TRIM28 and SETDB1 also emerged in pregnant vs. nonpregnant women and in blood, chorion, and decidua of mothers with MS vs. healthy mothers. In contrast, HERV and TRIM28/SETDB1 expressions were comparable between their neonates. These results show that gestation is characterized by impaired expressions of HERVs and TRIM28/SETDB1, particularly in mothers with MS. Given the beneficial effects of pregnancy on MS and the wealth of data suggesting the putative contribution of HERVs and epigenetic processes in the pathogenesis of the disease, our findings may further support innovative therapeutic interventions to block HERV activation and to control aberrant epigenetic pathways in MS-affected patients.
Evaluation of Wastewater Discharge Reduction Scenarios in the Buenaventura Bay
Authors: García-Rentería Francisco-Fernando , Nieto Gustavo Ariel Chang , Cortez Gustavo Hernández
Published: March 2023

Buenaventura Bay is facing severe pollution due to the direct discharge of untreated wastewater from 695 outlets along the coast, which serves 500,000 people. To address this issue, a study was conducted using the RMA11 water quality model, which was previously calibrated and validated, coupled with the RMA10 3D hydrodynamic model to assess sanitation scenarios in the bay. Five effluent reduction scenarios were proposed and compared based on fecal coliform concentration as an indicator, with evaluation also based on areas where fecal coliform concentrations exceeded the standard for primary contact. The model results revealed poor water quality in the bay, indicating that immediate action was necessary to prevent further deterioration. The proposed staged reduction in discharges would initially have more severe effects than the current situation, but this would improve when the treatment plant became operational. However, even with the plant in operation, the complete sanitation of the bay cannot be achieved, and further measures are required. This study emphasizes the urgent need for effective and sustainable measures to improve water quality in Buenaventura Bay and demonstrates the usefulness of the modeling approach in identifying effective sanitation scenarios to achieve this goal. The results highlight the need for a comprehensive management strategy to tackle pollution in the bay and provide insights for other regions facing similar challenges.
Comprehensive Evaluation of Water Resource Characteristics in the Northern Yangtze River Delta, China
Authors: He Liang , Xu Chenfang , Lei Shaohua , Chen Ling , Chen Suozhong
Published: March 2023

The Yangtze River Delta is one of the most economically developed regions on the eastern coast of China. However, a local imbalance currently exists between its water resource environment and economic and social development due to its rapid urbanization. Thus, the reasonable evaluation and protection of local water resources are necessary. This study explores the northern Yangtze Delta, which is a more developed water system, as a pilot area. The temporal and spatial variation characteristics of rainfall and evaporation and their influencing factors were analyzed on the basis of 29 surface water sampling points, 16 rainfall stations, and three evaporation stations in the field from 1956 to 2019. Accordingly, the overall water supply quality of the river basin, the availability of different water resources, and the application of evaluation methods were assessed. Results show that local precipitation and evaporation are characterized by uneven spatial and temporal distributions in local areas, which, in turn, leads to the uneven temporal distribution of runoff, increasing the imbalance between the availability and demand of the limited local water resources. Nevertheless, the overall performance of local water quality is good. Surface water quality is mostly Ⅱ to Ⅲ, and locally Ⅳ. Most noncompliant months are during the non-flood season, and all values exceed the standard permanganate index. Groundwater is Class III or better, and the hydrochemistry type is predominantly calcium bicarbonate, sodium bicarbonate, and magnesium bicarbonate. By exploring the evaluation model of the Yangtze River Delta watershed characteristics, this study aims to provide a helpful reference for extending water resource evaluation in the Yangtze River Delta. Accordingly, this study can promote the sustainable development of the economic and social sectors of the Yangtze River Delta and the construction of its ecological environment.

Published: March 2023

This manuscript presents the advances of a pilot testing, located in Spain, using ultrafiltration (UF) membranes to supply drinking water. These results could be extended to the islands of the Macaronesia area, for instance, Azores, Madeira, Canaries, and Cape Verde. The UF project targeted by the pilot activity is a refurbishment of an existing installation. The existing installation is located at a higher altitude, thus drinking water could be supplied to most of the island without further pumping, reducing the carbon footprint, ecological footprint, and energy consumption. The raw water is soft surface water (mainly of rainwater origin) coming from a dam. On the islands of Macaronesia, water is a scarce resource in high demand. Therefore, this is a technically and economically viable business opportunity with a promising future for isolated water treatment systems to produce drinking water on islands. The Macaronesia area is formed by volcanic islands with a small surface in the Atlantic Ocean, so usually there is not enough space for conventional technology and only a compact UF can be used. The raw water quality is not satisfactory and the municipality receives many complaints from end users, thus a potable water plant with UF membranes is in high demand to supply drinking water of good quality. Membrane processes can be categorized into various, related methods, three of which include the following: pore size, molecular weight cut-off, and operating pressure. Regarding the obtained results, the UF system successfully produced excellent filtrate quality with turbidity readings on average less than 0.03 NTU; furthermore, membrane instantaneous flux of 90 Lmh at 14 °C is achievable with long-term stability under various feed water conditions, peak operations are available at 105 Lmh without a large impact on the filtration performance of the modules, and CIP is only to be performed if the TMP increase reaches the terminal point.
Comprehensive Comparison of Various Microplastic Sampling Methods in Sea Water: Implications for Data Compilation
Authors: Shi Haochen , Wang Xiaohui , Zhu Lixin , Li Daoji
Published: March 2023

The problem of plastic and microplastic (MP, <5 mm in size) pollution has received widespread attention globally, with its widespread presence being reported in various environmental media. However, a lack of standard sampling and analysis methods is making it difficult to compare data across studies and understand the source and fate of plastics and MPs. Common sampling strategies used in studies of MP in natural waters include Manta net and pump filtering using different mesh sizes, but the impact of these sampling technologies on the final MP abundance and characteristics is not well understood. This study used common sampling devices, including a Manta trawl net, shallow-water plankton pump (SPP), deep-water plankton pump (DPP), and submersible pump with on-site filtration using 50 and 330 µm aperture size meshes, to sample MP in natural coastal water. The results showed that while Manta trawl and plankton pumps produced similar MP abundance (2.0–6.0 n/m3), the MP characterization was significantly different, with fibers being the dominant MP in plankton samples (>70%) and only 14.2% in Manta trawl samples. Submersible pump sampling using a 50 µm mesh retained a higher percentage of fibers, with a two magnitude higher abundance of MPs (357 ± 119 and 553 ± 19 n/m3 for 330 µm and 50 µm mesh, respectively) attributed to the floating debris encountered during sampling and the shallower sampling depth as well as smaller sampling volume. This study highlights the key factors that impact MP abundance and characteristics as well as the challenges to harmonizing MPs sampling methods in aquatic environments, which is also helpful for data compilation across studies.
Development of a One-Parameter New Exponential (ONE) Model for Simulating Rainfall-Runoff and Comparison with Data-Driven LSTM Model
Authors: Lee Jaenam , Noh Jaekyoung
Published: March 2023

Runoff information can be used for establishing watershed water management plans. However, hydrological models with complex parameters make it difficult to quickly estimate runoff. This study developed a one-parameter new exponential (ONE) model for simulating rainfall-runoff using a single parameter, which was designed based on a nonlinear exponential function and watershed water balance that varies according to the soil water storage. The single parameter was included in the runoff function and implemented to continuously track the state of the soil water storage based on the watershed water balance. Furthermore, to validate the model’s effectiveness, it was applied to two multipurpose dams in Korea and the results showed that the daily results of the ONE model were better than those of a learning-based long short-term memory model in terms of the quantitative evaluation indices, monthly heatmap and annual runoff rate. This study demonstrated that rainfall-runoff can be simulated using only one parameter and that minimizing the number of parameters could enhance the practical utility of a hydrological model. The use of a single parameter is expected to maximize user convenience for simulating runoff, which is essential in the operation of water resource facilities.

Published: March 2023

To understand the community structure dynamics of fish eggs and larvae in the Yellow River estuary, four trawl surveys were annually conducted between 2011 and 2014, including at 13 stations in 2011 and 18 stations between 2012 and 2014. A total of 2540 eggs and 143 larvae were collected during the four surveys, comprising 25 species, 8 orders, 16 families, and 20 genera. During the survey period, species numbers of eggs first decreased and then increased, while abundances first increased and then decreased. Larval species numbers exhibited the same trends as for eggs, while larval abundances fluctuated across the four years of the study. The primary species represented by the eggs were Konosirus punctatus, Sillago sihama, and Cynoglossus joyeri, while the larval species primarily comprised Amblychaeturichthys hexanema, Chaeturichthys stigmatias, and Engraulis japonicus. Cluster analysis of species compositions for eggs and larvae revealed the presence of four groups, wherein groups 1–3 comprised communities from 12, 3, and 2 stations, respectively, that were primarily distributed in the eastern part of the estuary. In contrast, group four only comprised communities from one station at the western part of the estuary near Bohai Bay. All biodiversity indices were lowest in 2012 and biodiversity of fish egg and larval communities were most correlated with the water depth among the parameters that were measured. Overall, interannual variation in the distribution and diversity of fish egg and larval communities in the Yellow River estuary reflected the responses of fish to environmental variability.

METHODOLOGICAL BASIS FOR DETERMINING THE RANGE OF THE FREIGHT RATE IN TRUMP SHIPPING
Authors: Timchenko T , Aslanov G.
Published: March 2023

Trump shipping, despite large quantitative and qualitative changes in the composition of the world fleet, the

emergence of new forms of organization of maritime transport, continues to be one of the most important elements

of international trade. The global freight market for tramp tonnage is a market of perfect competition for

the following reasons: a large number of sellers and buyers of homogeneous products independently operate

on it; each of them cannot significantly affect the level of freight rates and has fairly complete information

about prices and costs. Due to the fact that tramp ships are not associated with a specific navigation area and

go where there is a need, the tramp market is sensitive to changes in supply and demand, it is characterized by

significant fluctuations in freight rates. In this regard, the research topic is relevant.

Within the framework of the article, the authors propose a methodical approach to determining the possible

range of freight rates in tramp shipping, taking into account the input parameters of the upcoming voyage and

the current state of the freight market. The practical calculations carried out allowed us to conclude that today

for ships of the size "Handymax" in the geographical section of the Black Sea-Mediterranean Sea, the gap

between the minimum and maximum possible freight rates for ships of the same age can reach four dollars per

1 ton of cargo

The article proposes the development of methods for compensating for distortions occurring when specifying

the following types of forward-backward movement, swinging port-starboard, turning to port-starboard and

their combinations.

Uncompensated stops lead to uncontrolled turns of remote-controlled devices when setting any of the types of control.

The controllability of underwater remote-controlled vehicles is associated with the limited field of view of the phototelevision

complex in conditions of artificial lighting and a limited observation range, usually 5-7 meters.

The developed technology can be used for various remote-controlled and autonomous mobile objects, the power

Published: March 2023

The purpose of the study is to analyze the publishing activities of scientists of the Odessa association of History and Antiquities and to determine their contribution to the military-historical research of the Dnieper Ukraine Ukraine and the Crimean Peninsula. The methodology of the study is based on the principles of historicism, systematic, scientific, interdisciplinary. The following general historical methods have been used: historiographic analysis, historical-genetic, terminological analysis, comparative, typological. The author adheres to the civilization approach. Scientific novelty: the contribution of the Odessa association of History and Antiquities to the military-historical studies of the Dnieper Ukraine and the Crimean Peninsula is characterized on the basis of a wide range of published researches. Conclusions. Along with general archeological, the association presented studies related to military archeology and military history. The problems identified were raised in the publications of scientists: F. Brun, K. Stamati, I. Karelin, O. Kochubinsky. Military-historical studies were presented in several areas: topography, study and protection of fortifications, military confrontation of the Russian and Ottoman empires, history of Ukrainian Cossacks. The problems concerned the South of Ukraine, Crimea, Bessarabia. Particular attention was paid to the fortresses in Akkerman, Khotyn, Ishmael. The main topics of the publications were the Russo-Turkish wars, as well as individual episodes and processes related to them. A profound, professional analysis of events, in publications, combined with political engagement and duplication of existing imperial ideologues. Archaeographic surveys mainly concerned personal sources that reflected the local governance of Russian military officials in the Black Sea Fleet and fortifications, and described Turkish and Tatar campaigns. Although the research was largely sporadic, it resulted in the publication of a considerable amount of material and concentration in the Museum of the Society of Antiquities and Cartographic Sources.
Camp «live» newspaper «Ray» as a source for the reconstruction of the peculiarities of life and the daily life of interned soldiers of the UPR army in Strzalkowo, Poland (first half of 1922)
Authors: Sribnyak Ihor , Paliienko Maryna ,   Borys Grinchenko Kyiv University,   Taras Shevchenko National University of Kyiv
Published: March 2023

The article analyzes the source potential of the materials of the camp «living» newspaper «Ray», which was issued by interned Ukrainian soldiers first in the Lancut camp (Poland), and from the very beginning of its withdrawal it won the favour of the vast majority of the campers. After their relocation to Strzalkovo, the magazine continued its life in the old format – when the editorial board prepared 2-3 copies of «Ray» (typing them), after which his materials were distributed weekly in the camp by saying them to the generally interned from the stage of the camp theatre. Thanks to this practice, the magazine has become an integral part, and campers have been looking forward to its next issues – to hear a lively and sharp Ukrainian word, which branded various negative aspects of the camp's everyday life. At the same time, its editors faced many difficulties in preparing almost every issue of the magazine, which were due to the banning of some of its materials by censorship, and the reluctance of individual campers to become the target of sharp satirical notes. At the same time, the command of a group of interned troops understood the usefulness of such a publication to maintain the morale of the military. The camp newspaper «Ray» became a real chronicler of the camp, because the materials published in its columns contained a significant amount of information about the life and everyday life of interned Ukrainian soldiers in Strzalkovo. Most of these materials were placed in the section «Camp life», and their study allows you to get valuable facts about the peculiarities of the life of campers, their main occupations and leisure. At the same time, the newspaper published critical articles that touched on many acute issues, including on the unwillingness of some officers of the Army Ukrainian People's Republic to use the Ukrainian language at work and in everyday communication, official and extra-official relations of officers and Cossacks, unworthy behaviour of certain employees of the camp commandant's office. Throughout its publication, the newspaper has had a powerful influence on the process of forming the worldview of campers, encouraging them to participate in fundraising for various important social needs. This position of the editorial board of the magazine provided him with moral support from the majority of the interned army, for which the publication of each issue of the newspaper became an event in the gloomy camp life. Despite all the difficulties of camp isolation, the editorial board found opportunities to obtain news and socially significant information and publish it on the pages of «Ray». By publishing materials about the sanctity and invincibility of the Ukrainian liberation struggle, the newspaper always stood in defence of the national-state ideals of the Ukrainian People's Republic.

The sudden transition has caused a chaos in the education sector in India. Many studies have been conducted on the issues faced by the students in online classes but not teachers. The higher secondary school teachers are a group who has to adapt immediately to the digital classrooms and resources since their students are at a stage of their prospective career choosing. The present study analyses the issues of teachers during online teaching who are suddenly pushed in to the digital environment. The case study method was adopted for the study with the support of a structured interview schedule. The sample of the study consisted of 50 higher secondary teachers in different disciplines and different schools across Kerala, India. Due to the pandemic restrictions the sample size has to be kept a minimum number. The study mainly focused on the problems faced by the higher secondary teachers during the online teaching. The findings of the study showed that the online teaching is a pressure for them rather than a pleasure experience. Major issues faced by the teachers are the lack of computer competency, technical issues such as lack of internet connectivity, students’ access to the digital devices and the occupational stress due to the disruption of work- life balance. Based on the findings, practical and social implications are analyzed and discussed.
