Assessment of Multi-Bus Power Network Stability
to Forecast System Collapse
Authors: Parihar Manish , Bhaskar M.K.
Published: May 2024

Voltage stability is an important consideration in power system operation, and the development of voltage stability indices is a key aspect of ensuring the reliability and security of the power grid. In this work, newly constructed voltage stability indices have been discussed that are designed to predict the closeness of a multibus system to voltage collapse. These stability indices are based on the analytical expression of complex power, which allows for a more accurate characterization of the system’s voltage stability. By using these indices, operators can gain a better understanding of the system’s stability and take appropriate actions to prevent collapse. To test the effectiveness of the newly developed index, it was applied to the IEEE bus system. The results showed that the index was able to accurately predict voltage instability or the proximity of a collapse. This is an important step in improving the reliability and security of the power grid, as it allows operators to take preemptive measures to avoid voltage collapse. Overall, the development of these new voltage stability indices is a positive step towards improving the performance of power systems. By providing a more accurate and reliable prediction of voltage instability, these indices can help prevent costly and potentially dangerous system failures.

Published: May 2024

Determining the precise location of a ship navigating on a lake is of utmost importance for various logistical and safety reasons. However, this task can become particularly challenging when operating in regions with limited or no access to the Internet. Fortunately, advancements in technology, specifically the Internet of Things (IoT) utilizing Low Power Wide Area Network (LPWAN) technology, have offered a robust solution to address this issue. LPWAN technology enables long-range data transmission without being reliant on traditional internet connectivity.
In the context of our research, a LoRaWAN end node is employed equipped with LGT92, along with three gateways sourced from two different vendors, to effectively track the real-time position of a ship. To gauge the effectiveness of our system, let’s conduct experiments and obtained significant results. One noteworthy finding was that the communication range between one of the gateways and the LoRaWAN end node extended to 2.5 kilometers when utilizing the RAK 7243 gateway. In contrast, the Dragino LG308 gateway impressively stretched this range to 5.7 kilometers. All three gateways to broaden the tracking coverage area and ensure comprehensive monitoring are strategically deployed.
Our research's primary focus was tracking a ship's journey spanning 16 kilometers from Balige to Onanrunggu port. Throughout our experimentation, it is confirmed that the ship's precise coordinates, including latitude and longitude, were accurately transmitted from the end node on the ship to the designated gateway. This crucial position data was then seamlessly transmitted to the cloud. This real-time tracking capability proved invaluable, allowing for constant oversight and decision-making support during the ship's journey

The proposal in the efficient algorithm in this work is a method to derive the two new filters from the second and third Chebyshev polynomials by forming the discrete wavelets with the mother wavelet to be used in image processing in order to overcome the problem mentioned above due to the correspondence, The filters that were derived are Filter Discrete Second Chebyshev Wavelets Transform (FDSCWT) and Filter Discrete Third Chebyshev Wavelets Transform (FDTCWT)to process the image by analysis, noise reduction, and image compression.
Many of the techniques previously used in the field of image processing do not preserve image information during processing, but when using the new technology proposed in this work, it has been proven to preserve the image with its important information and data through the readings obtained shown in the tables below. These readings are average. Mean Square Error (MSE), Peak Signal Noise Ratio (PSNR), Bits Per Pixel (BPP), and Compression Ratio (CR) in preprocessing.

Study on optimal water hammer protection for high-head and multi-undulation water conveyance system and empirical formulae for pressure head at nodes
Authors: Li Liutao , Li Zhiwei , Wang Feifei , Sun Bin , Zhao Shuaikang , Zhang Haifeng
Published: May 2024

The high-head and multi-undulation water conveyance system, which has a complex pipeline structure, can be prone to water hammer accidents. To prevent damage caused by pipe explosions and dents, measures must be taken to reduce both overpressure and negative pressure during water hammer incidents. This study simulated hydraulic transients using the characteristic curve method and also considered the possible water column separation effect. Parameter optimization and joint scheme selection were conducted for protective measures on the compound air valve group, one-way surge tank, and two-way surge tank. The research identified that the combined protective effect of the slow-closed check valve, compound air valve group, and one-way surge tank is optimal, with low cost and simple operation management. This can be considered the optimal scheme for water hammer protection in the high-head and multi-undulation water conveyance system. The study of the main control points of the pipeline revealed a slight correlation between the maximum relative head differences among nodes. Two empirical formulas, verified under 12 operating conditions, can connect the 9 main nodes with an average relative error mostly ranging from 1 to 5%. The reference significance of the empirical formula for this type of engineering can be verified.
Implications of the operation of continuous granular activated carbon filters on the effluent quality
Authors: Kirchen Franziska , Fundneider Thomas , Lackner Susanne
Published: May 2024

Granular activated carbon (GAC) filtration is a commonly used method for advanced wastewater treatment. Filters can be operated continuously or discontinuously, with continuous operation not requiring feed flow interruption for backwashing and circulation (B/C). This study investigated the influence of B/C on the effluent quality of continuous filters. Two continuous GAC filters were operated for 1.5 years, with analysis of dissolved substances and particulate matter in the influent and effluent. The results indicated that various B/C modes had no impact on the removal of dissolved organic carbon and organic micropollutants (OMP), achieving an OMP removal of over 70% after 5,600 treated bed volumes (m3 treated wastewater per m3 GAC). However, it was evident that continuous B/C over 2–4 h resulted in increased turbidity, total suspended solids over 30 mg/L and total phosphorus concentrations of 1.3 mg/L in the filter effluent. Additionally, the study demonstrated that longer and more intensive B/C processes resulted in GAC size degradation with AC concentrations of up to 6.9 mg/L in the filter effluent, along with a change in GAC particle size. Furthermore, the importance of pre-filtration in reducing particulate matter in the filter influent and decreasing hydraulic head loss could be demonstrated.

Authors: Kadiravan Madhivadhani , Kanagarajan Hemalatha
Published: May 2024

Introduction:

A 9-aminoacridine derivative has anticancer properties against several
types of cancer cells, including colon, breast, pancreatic, lung, and renal cell carcinoma. It triggers
apoptosis by stopping the cell cycle in the S phase and inhibits the activity of topoisomerase.
So, the present study deals with the synthesis and anti-cancer activity of some of the acridine derivatives.

Methods:

The novel set of N-(acridin-9-yl)-N-(2-substituted benzoyl) derivatives were synthesized,
and these compounds were subjected to docking studies against topoisomerase II and the
result of docking studies revealed that all the compounds possessed promising activity against the
targeted enzyme. The docking studies revealed that the derivative AB7 showed a good docking
score of -8.7 kcal/mol when compared to doxorubicin.

Result:

The following derivatives AA2, AA3, AB3, AB7, AB7, AF6, AF10, AP7, AP10, and
APZ7 were selected for the synthesis by conventional method and further studies. These compounds
weresubjected to an in-vitro cytotoxicity study using the MTT assay method with MCF-7
cell lines. Among the tested compounds, derivative APZ7 substituted with chlorobenzene and
pyrrole ring showed a significant IC50 value (46.402 μg/ml), and the compound AP10 substituted
with chlorobenzene and pyridine moiety (59.42 μg/ml) exhibited promising inhibition in breast
cancer cell line.

Conclusion:

The current study suggests that the most effective anticancer compounds are found
in the substituted acridine derivative.
Octocorals in Turbid Waters – An Untapped Source of Potential Bioactive Molecules
Authors: Chandran R. , Padmakumar K. , Satyanarayana Ch. , Kumaran R. Senthil
Published: May 2024

Discovering new secondary metabolites is an especially urgent task due to
the rapid spread of bacterial resistance and the emergence of multi-resistant pathogenic
strains of infectious diseases. Octocorals (soft corals and gorgonians) are a highly
diverse group of marine organisms, which are known to contain a rich variety of rare
and unusual secondary metabolites. These substances show not only great significance
in chemical ecology but also various biological activities. Despite the intense interest in
the isolation of novel compounds from octocorals, little is known about within and
between-habitat variability in the levels and types of compounds in these species.
Marine organisms living in extreme environments evolve unique strategies by
biosynthesizing more diverse compounds than their counterparts living in moderate
environments. Coral reefs of the Gulf of Mannar in India have a more moderate
environment (with a sedimentation rate of 12.31 mg.cm-2day-1); whereas the Gulf of
Kachchh is a marginal reef experiencing arid climate and heavy sedimentation rate
(upto119.60 mg.cm-2d
-1). In a preliminary cytotoxicity assay, carried out to evaluate the
bioactivity of selected soft corals from the Gulf of Mannar and the Gulf of Kachchh,
the highest cytotoxicity was exhibited by Mannar soft corals, Sinularia leptoclados
(LC50=25.15μg/ml) followed by Sarcophyton ehrenbergi (LC50=43.76μg/ml). Whereas
soft corals collected from the Gulf of Kachchh exhibited higher cytotoxicity than the
Mannar samples (Si. leptoclados (LC50=19.24μg/ml) followed by Si. polydactyla
(LC50=24.50μg/ml). Extreme physico-chemical and biological conditions in the
Kachchh are the drive for the production of variant molecules with specific adaptations.
Hence, soft corals inhabited in extreme waters may yield more effective compounds that may potentially be useful in drug development for existing and emerging human
ailments.

Authors: Zhao Xinpeng
Published: May 2024

The digital transformation of manufacturing enterprises is in full swing. In practice, they often face the problems of resource constraints, lack of digital capability and changing environment, which leads to the dilemma of digital transformation. This paper uses the exploratory case study method to construct the strategic construct of digital transformation of manufacturing enterprises: The process of transforming enterprise strategy by applying digital technology under the leadership of senior management is an all-around transformation of enterprise organizational structure, operating process, business model and value creation mode. Case studies define the core concepts of this paper and discover the direct role of digital transformation strategy on digital innovation performance, the mediating role of resource patchwork and the mediating role of digital empowerment. Based on the results of case analysis and existing literature and theories, the research hypothesis is proposed and verified by empirical research. The results show that: (1) digital transformation strategy positively affects digital product and service innovation, performance and digital process innovation performance; (2) Environmental dynamics positively moderates the relationship between digital transformation strategy and digital process innovation performance, but has no significant positive moderating effect on the relationship between digital transformation strategy and digital product and service innovation performance. (3) Resource patchwork plays a partial mediating role between digital transformation strategy and innovation performance of digital products and services.

Published: May 2024

Oyster Crassostrea spp. is the bivalve mollusk with the largest commercial volume in Cuba. Populations should be assessed for their management and conservation, which has been performed but with different methodologies and only in certain localities, making it difficult to evaluate and compare between periods and regions. Therefore, current state of the resource was to be determined according to maximum sustainable yield (MSY), biomass for the maximum sustainable yield (BMSY), and corresponding fishing mortality rate (FMSY). Catch Maximum Sustainable Yield (CMSY) model was applied with Monte Carlo method, resource biomass and exploitation were evaluated for northwestern (NW), northeastern (NE), southeastern (SE), and southwestern (SW) regions of the insular platform, as well as for periods (1960-1991 and 1992-2020). From 1992-2020, a 50% reduction in oyster landings was recorded when compared with 1960-1991 period, which was reflected in population indicators according to estimated fishery reference points. Based on applied model and method, current oyster fishery management is perceived as unsustainable with stock depletion and overfishing in NW, NE, and SW regions. Cuban SE region shows a more favorable status. Oyster farming should increase to obtain higher production and broodstock biomass to decrease fishing effort on wild populations.

This article deals with the development of new trends in administrative procedure in the context of administrative legislation with a specific view of the Republic of Kosovo. This article analyses the status of the development of administrative procedures in a general aspect with a specific view in the Republic of Kosovo toward the further need for new trends and simplification of procedures in light of social changes and in harmony with European standards that intend the protection of the public interest and protection of rights of natural and legal persons. Data study presumes on factual approach, an examination of the current legal framework ruling the administrative system, different government, and non-government reports on the effective functioning of the administrative procedures, empirical studies of the researched issue, managed cases, and other relevant issued papers. This research article presents an important implication seeking to promote the new models of an administrative system towards an administration that advances the rights of the party in the procedure by simplifying the procedures and providing more efficient and inexpensive services for citizens. For several decades, a dynamic development of the European Administrative Space (EAS) has been recognized, which can be best characterized as the growth of administration at the European Union (EU) level, with the consequent gaining of new powers (Siuciński, 2020). This study assumes that legal provisions from the administrative field should be more dynamic, adapting to the recent changes and transformation of social relations, especially the development of information technology (IT), enabling more modern, efficient and non-bureaucratic procedures.
Random forest regression on multi-platform in-situ ocean observations: Investigating high-frequency nutrient dynamics in the Southern Ocean
Authors: Song Sangmin , Lavin Paige D , Gray Alison R , Nachod Zachary , Balwada Dhruv , Dove Lilian A , Thompson Andrew F
Published: May 2024

Nutrient cycling in the ocean is mediated by physical mixing processes
that span diverse spatial and temporal scales. New biogeochemical
profiling floats (BGC-Argo) have begun to observe nutrient distributions
globally, but their 10-day cycling period limits the types of processes
they can capture. Small-scale dynamics, occurring on
O(1) day and O(1) km, remain
particularly difficult to observe in-situ. Here, we show that random
forest regression (RFR) can recover high-frequency information by
leveraging the sampling strategies of multiple ocean profilers. Our RFR
is trained, validated, and tested on BGC-Argo and shipboard data to
within ~3% accuracy, then applied to observations from
two rapid-sampling Seagliders deployed during the Southern Ocean Glider
Observations of the Submesoscale (SOGOS) experiment in 2019. This
approach generates novel nitrate distributions at 50 times the
horizontal resolution of the original float data. Using the
high-resolution RFR outputs, we identify signatures of nutrient
injection into the mixed layer that coincide with enhanced stirring in a
turbulent region downstream of the Southwest Indian Ridge. Relating
these intermittent transport events to biological time series suggests
that small-scale stirring mediates additional nutrient drawdown and
primary production in this region. In our exploration of high-frequency
nitrate variability in the Southern Ocean, RFR extends the capabilities
of the BCG-Argo array and allows for deeper understanding of
biogeochemical cycling at a more comprehensive set of scales. As a
flexible approach that can be generalized to suit other multi-platform
observing systems, RFR presents new opportunities to maximize value from
existing datasets.
Observed regional impacts of marine heatwaves on air-sea CO2 exchange
Authors: Li Catherine , Burger Friedrich Anton , Raible Christoph , Frölicher Thomas Lukas
Published: May 2024

Marine heatwaves (MHWs) have devastating effects on ecosystems and
impact regional air-sea CO2 exchange. Yet a global assessment of these
regional impacts of MHWs on the air-sea CO2 exchange is missing. Here,
we analyze thirty global observation-based air-sea CO2 flux datasets
from 1990 to 2019. We observe minimal reduction in global oceanic CO2
uptake during MHWs. Regional variations are evident with the equatorial
Pacific experiencing a 31% (spread across datasets: 3-49%) reduction
in carbon release, suggesting that MHWs are the dominant drivers of
strong air-sea CO2 flux anomalies in this region. In low-to-mid
latitudes, MHWs cause a 29% (19-37%) decrease in air-sea CO2 uptake.
Reduced dissolved inorganic carbon in the tropics weakens outgassing,
while high ocean temperatures diminish uptake in the low-to-mid
latitudes. In the North Pacific and Southern Ocean, enhanced carbon
uptake occurs during MHWs, but uncertainties in pCO2 datasets limit a
comprehensive assessment in these regions.

Published: May 2024

The objective of this study is to outline the issue of government-provided disaster relief management (JKMM) for flood victims during a disaster. Additionally, it examines communication and the planning of goods movement as key elements in determining the efficacy of Humanitarian Supply Chain Management (HSCM). This study focuses on the staff of the Social Welfare Department (JKMM), namely those from the Disaster Management Department and other agencies. The analysis of this research relies on a distinct dataset acquired from a survey conducted among the staff members. Researchers can more easily get quantitative measurements to analyze data on respondent variables. The operational sample comprises 137 participants. The study reveals that enhancing aspects related to the movement of goods and communication is crucial for improving the efficacy of HSCM. JKKM should ensure sufficient vehicle availability while simultaneously striving to minimize communication obstacles, such as limited network coverage. This paper stands out because of its unusual approach since it examines the challenges faced by the government agency (JKMM) in managing products for flood victims. This perspective sets it apart from earlier studies, which primarily focused on the experiences of flood victims and evacuation centers in Malaysia.

A systematic approach for design of distributed wastewater treatment systems
Authors: Eid Alaa , Abdel-Aleem Galal
Published: May 2024

Due to increasingly strict environmental regulations, the cost of handling various waste streams is gradually rising. Therefore, it is crucial to minimize unnecessary stream merging when designing distributed wastewater treatment systems, to reduce the overall treatment flow rate whenever possible. In a distributed wastewater treatment system, the wastewater streams are separated for treatment and only combined when necessary. This results in a significant reduction in the total treatment flow rate compared to traditional centralized treatment systems where all the streams are merged before treatment. Design of a distributed wastewater treatment system can be accomplished using pinch analysis and mathematical programming approaches. This paper suggests a straightforward approach for designing such networks, with the following steps in the design process: First, the primary function of each treatment unit is determined. Next, using the pinch method, the lowest treatment quantity is determined for the primary pollutant for each unit. Finally, a three-unit group is selected, with the pinch stream partially treated, the streams above the pinch completely treated, and the stream below the pinch completely bypassed. Two literature case studies demonstrate the viability and effectiveness of this strategy.

На горе Сандыревой и в ее окрестностях (национальный парк «Русский Север») с 2019 г. проводятся исследования популяции цикады горной. В результате наблюдений 2022 г. уста- новлены даты фиксации первого экзувия личинки цикады горной и встречи первого имаго, а также обнаружены повреждения древесных растений: яблони, шиповника, рябины обыкновенной, кру- шины ломкой, жимолости, можжевельника и малины, нанесенные предположительно яйцекла- дом цикады горной. Собраны сведения по размеру повреждений и их расположению на побегах, описан внешний вид, приведены данные по высоте поврежденных растений. Полученная инфор- мация сопоставлена с немногочисленными сведениями, содержащимися в открытых источниках.

The studies of the mountain cicada population have been conducted on M. Sandyreva and its surroundings (“Russian North” National Park) since 2019. The results of observations (2022) include the date of fixation of first exuviae of the mountain cicada larva and first imago appearance, as well as detected damage of such woody plants as an apple, a rosehip , a mountain ash, a brittle buckthorn, a honeysuckle, a juniper, and a raspberry. The plants were damaged presumably by ovipositor of the mountain cicada. The authors have collected the information on a damages size and their location on shoots, described the appearance, and specified a height of damaged plants. The data obtained was compared with the related scanty information present in the open sources.

A comprehensive survey was conducted during March 2022– October 2023 in various forest areas including Pusa Hill Forest, Alipur City Forest, and Jahanpanah City Forest, New Delhi, India to study Oxyrachis tarandus, cow horn bug or treehopper on Ficus benghalensis. This study utilized both morphological and molecular techniques for accurate species identification, revealing a significant association between O. tarandus and F. benghalensis. Morphological identification relied on established criteria, which included measurements of adult insects and the observation of distinctive features such as wings and horns. On the other hand, molecular identification involved DNA extraction from collected specimens, followed by PCR amplification targeting a fragment of the MT-COI gene. This approach facilitated precise species identification and allowed for the construction of a phenogram to analyze genetic relationships within the studied population. Phenogram construction and analysis were conducted to further validate species identification and explore genetic relationships. The treehopper’s feeding behaviour, oviposition habits, and ecological interactions were thoroughly documented, highlighting its potential impact on the banyan tree’s health and ecosystem dynamics. This information underscored the necessity for ongoing monitoring and development of effective pest management strategies to conserve India’s national tree and forest biodiversity. The study revealed the critical need for ongoing research and conservation efforts to address pest-induced threats to iconic tree species like F. benghalensis, thereby ensuring the long-term health and resilience of forest ecosystems.

The study was undertaken at two locations during kharif (June to October, 2021), at College Farm, College of Agriculture, Rajendranagar, Hyderabad, and Regional Sugar Cane and Rice Research Station, Rudrur, Nizamabad, to find out the most effective crop stage for managing false smut of rice through fungicide spraying. Our study evaluated three fungicides viz., propiconazole 25 EC, carbendazim 50% WP, and tebuconazole 50%+trifloxystrobin 25% w/w WG (75 WG) against false smut disease of rice under in vitro and field condition. Under in vitro, U. virens showed greater sensitive to tebuconazole+trifloxystrobin, with complete mycelial growth inhibition at minimum concentration (0.25 µg ml-1), followed by propiconazole (1 µg ml-1) and carbendazim (2.5 µg ml-1). Under field management, fungicides propiconazole 25 EC @ 1 ml l-1, carbendazim 50% WP @ 1 g l-1, and tebuconazole 50%+trifloxystrobin 25% w/w WG (75 WG) @ 0.8 g l-1 were sprayed at different crop growth stages (10% panicle emergence, 50% panicle emergence and a combination of both crop stages). The results indicated that two sprays of fungicides, first at 10% panicle emergence and another at 50% panicle emergence were more effective, followed by a single spray at 10% panicle emergence and 50% panicle emergence. Among the three fungicides, tebuconazole 50%+trifloxystrobin 25% w/w WG (75 WG) at 0.8 g l-1 was highly effective in reducing the false smut disease intensity and increasing the yield compared to control.

Being the tourist activity transversal to the different socio-economic sectors of the communities that frame the integration of elements such as cultural identity, natural and architectural heritage considered as a fundamental part of the tourist inventory of any society, it is imperative to investigate the relationship that exists between them to formulate effective digital marketing strategies that promote not only the sale of services and/or tourist packages, but also allow the management carried out in the tourist activity to focus on highlighting and transferring the cultural idiosyncrasy and the preservation of heritage as a promoter axis of civilization and the evolution towards sustainable and sustainable tourism.It is in the execution of the tourist activity where the deep relationship that exists between these elements is evidenced and manifested, precisely at the moment of truth after the encounter between the inhabitants of a region and/or community and the tourists and visitors who arrive with realities multidiverse cultures. This interaction and knowledge of new cultures can directly impact and influence the dynamics of the cultures of the receiving communities as well as the visitors within the context of the tourist activity. The symbiotic relationship between these elements and tourism is a source of knowledge and information for the design of digital marketing strategies that can be optimally used as tools for management and assertive communication that promote tourism with corporate social responsibility.
