High-torque and low-noise IPMSM multi-objective collaborative optimization based on multi-layer surrogate model
Authors: Li Xiaohua , li guangxu , han zhongchuan , han xu
Published: May 2024

To achieve efficient and rapid optimization for high torque and low
noise permanent magnet synchronous motors, this paper proposes a
multi-layer surrogate model-based optimization method for IPMSM
(Interior Permanent Magnet Synchronous Motor) based on sensitivity
classification of structural parameters. Firstly, using a hybrid model
of “FEM + Unit Force Wave Response,” the key order electromagnetic
forces causing electromagnetic noise in various operating conditions of
the motor are obtained. Their amplitudes, along with the motor’s average
output torque and torque ripple, are taken as optimization objectives.
By analyzing the sensitivity of structural parameters using the random
forest algorithm, the selection and classification of structural
parameters are achieved. A hierarchical optimization is then performed
using a combination of a multi-island genetic algorithm, a
multi-objective particle swarm optimization algorithm, and parameterized
scanning. Compared with traditional multi-field coupled optimization
methods, this method saves computational resources while reducing
calculation time by 54.9%. After optimization, the average output
torque is increased by 34.6% compared to before optimization, the
amplitude of key order electromagnetic forces of the motor is reduced by
13.7%, and torque ripple is reduced by 67.8%.

Published: May 2024

Prior to the present study, no dedicated in situ measurement of the
thickness distributions of fast ice and the sub-ice platelet layer,
formed by supercooled Ice Shelf Water in the near-surface ocean, had
been carried out in Terra Nova Bay. Previous studies have recognised the
biological importance of the sub-ice platelet layer observed beneath
fast ice beside the Campbell Ice Tongue. Furthermore, a recent airborne
survey of fast ice in the western Ross Sea implied that smaller ice
bodies (ice tongues and outlet glaciers) contribute to the formation of
supercooled Ice Shelf Water. With the objective of inferring source
regions and circulation of Ice Shelf Water, we measured fast ice and
sub-ice platelet layer thickness distributions near the Campbell Ice
Tongue in late spring of 2021, using drill hole surveys and
high-resolution ground-based electromagnetic induction soundings. We
observed thicker fast ice and sub-ice platelet layer near the ice tongue
with very thick and narrow sub-ice platelet layer maxima identifying
highly channelled outflow of supercooled Ice Shelf Water from beneath
the ice tongue through ice mélange, subglacial formations, and grounded
regions. We conclude that a significant volume of supercooled Ice Shelf
Water is locally sourced from the Campbell Ice Tongue through basal
melting and affirm that the icescape in north Terra Nova Bay results
from a complex interplay of glacial morphology, bathymetry, polynya
dynamics, and ocean circulation.

Az urológiai gyakorlatban mindennaposnak számít a felső húgyutak átjárhatóságának fenntartása érdekében felhelyezett húgyvezetékstent. Mint minden idegen test, amelyet emberi szervezetbe ültetünk, bakteriális kolonizációnak és ezáltal biofilmképződésnek van kitéve. A húgyvezetékstent felületén kialakuló biofilm további szövődmények lavináját indítja el, amely végső soron a stent elkövesedését okozza. Mindezen szövődmények skálája a kellemetlen tünetektől az egészen veszélyes állapotig terjedhet, amely a stent idő előtti cseréjét teszi szükségessé további kockázatot és megterhelést jelentve a páciensnek. A húgyvezetékstent felületén képződő biofilm megakadályozása végett kiterjedt vizsgálatok történtek és született számos megoldás, amelyek eltérő hatékonysággal veszik fel a küzdelmet. A biofilm elleni harc nem új keletű, azonban mind a mai napig időszerű. Összefoglaló közleményünkben a biofilmképződés folyamatáról és a húgyvezetékstent felületén végbemenő, biofilm elleni kezelés lehetséges stratégiájáról szeretnék áttekintést nyújtani.
Factors of social equilibrium shaping and preventing violence
Authors: Pavicevic Olivera , Bulatovic Aleksandra
Published: May 2024

The continuous landscape of violence that unfolds parallel to everyday life
undermines our sense of well-being, security, and trust in the effectiveness
of institutions that are evidently failing to guide individuals to act and
react in socially desirable ways. In the paper, the authors explore the
phenomenon of violence within the framework of objectively established
structures and the circumstances under which economic polarization and power
polarization dominate, arguing that mass shootings represent factors that
significantly influence the emergence and frequency of violence. Since moral
competence is one of the key resources of society for successfully coping
with adaptive demands, particularly during crises, increasing connectedness,
developing moral competence, and enhancing empathy are imperatives for
building a society that can consistently and effectively respond to the
(moral) challenges posed by its environment. The paper aims to point towards
ideas on violence prevention by affirming the importance of moral competence
in preventing violence, thereby preventing moral confusion, and reducing the
risk of society?s inadequate response to moral challenges.
Feature selection for coal heating level estimation in thermal power plants
Authors: Vujnovic Sanja , Cvetinovic Dejan , Bakic Vukman , Djurovic Zeljko
Published: May 2024

Several recently signed environmental agreements and protocols emphasize the global need to reduce GHG emissions, with a focus on limiting coal consumption due to high NOx and CO2 emissions. However, many countries, including those in the Western Balkans, rely heavily on coal for electricity generation. The outdated thermal power plant infrastructure in these regions poses a major challenge when it comes to meeting modern environmental standards while maintaining efficiency. This study is part of the more comprehensive research which aims to develop an expert system that utilizes existing measurements to estimate key parameters crucial for both energy production and pollution reduction. The focus is on Serbian thermal power plants, particularly plant Nikola Tesla unit B1. One of the critical parameters for optimizing thermal power plant control loops is the heating value of coal, which is challenging to measure in real time due to the coal?s varying chemical compositions and caloric values. This paper examines 74 different parameters measured in 59 instances to estimate the hating value of coal at unit B1. Through detailed analysis and feature selection methods, including linear regression, this research aims to identify the most informative parameters for estimating the heating value of coal, which will improve the control system that enables more efficient and environmentally friendly power generation in coal fired thermal power plants.
The situation and complexity of migration phenomena in the Republic of Serbia according to the 2022 census data
Authors: Santic Danica
Published: May 2024

The increasing volume of migration worldwide, the emergence of new forms of
mobility and the differentiation of the structural characteristics of
migrants have increased the challenges in terms of the complexity,
determinants and consequences of migration at local, regional and national
levels. For this reason, it is of utmost importance to deepen and broaden
research on spatial mobility at different territorial levels, requiring
greater availability of relevant and reliable data and the observation of
specific spatial bases and manifestations of this phenomenon. The paper
provides an overview of the main global development documents dealing with
migration issues, as well as an overview of the existing data sources for
monitoring this phenomenon in Serbia. The central part of the paper focuses
on analyzing the migration characteristics of the Serbian population
according to the results of the 2022 census. The census data demonstrate
that the autoch?thonous population predominates, the female population is
more mobile and long-distance migration has increased. The largest migration
centers are located in the north of the country in the gravitational zone of
Belgrade and Novi Sad, while the lowest mobility is recorded in the south in
the Pcinja and Jablanica counties. The city of Belgrade and the city of Novi
Sad, together with the tourist resorts (Vrnjacka Banja, Cajetina), are the
largest migration centers. The number of people born abroad (with the
exception of the countries in the region) has increased significantly. It is
clear that the census cannot be the only source of migration data due to
methodological limitations and incomplete coverage, but it provides a good
basis for further, more complex studies of migration systems and processes,
which are essential for determining the directions of future development and
finding mechanisms for migration management as elements of a strategy of
sustainable demographic and spatial development.

Published: May 2024

This study utilizes bibliometric analysis to examine the research published by the Journal of International Accounting Research (JIAR). JIAR was established in 2002 to disseminate high-quality accounting research that emphasizes international relevance and implications. First, we perform publication and citation analyses to identify the leading articles, authors, institutions, and geographic affiliations. Although U.S.-based authors account for most publications, authorship from Asia, Australia, and Europe is expanding. Second, based on thematic structure analyses, we identify nine key research themes among JIAR publications. Although studies relevant to international accounting remain the mainstay of the journal’s publications, other themes like corporate governance, auditing, and corporate social responsibility are growing. Our findings of successful diversification in authorship and topic areas over time attest to the contributions of past and present JIAR editorial teams in strengthening the research in international accounting and promoting accounting research internationally.

A Study on the Lateral Channel of Scytalidium Catalase
Authors: Y Yuzugullu Karakus
Published: May 2024

Catalases are antioxidant enzymes. Their main function is to convert hydrogen peroxide, one of the reactive oxygen species, into water and oxygen. A bifunctional catalase enzyme from Scytalidium thermophilum, which belongs to the monofunctional catalase family, exhibits oxidase activity in the absence of hydrogen peroxide without the need for a cofactor. It is able to oxidize a variety of ortho- and para-diphenolic compounds, but the oxidase activity is very low (~ 10,000-fold) compared to its main activity in peroxide degradation. In this study, an attempt was made to improve the oxidase activity of catalase for its industrial utilization. For this purpose, the residues located in the lateral channel (H214, D224, and K248), which are thought to play an important role in the access of oxidase substances to the active site, were selected and converted into an amino acid with a smaller side chain -Ala- by site-directed mutagenesis. The changes in the catalytic efficiency of the variants were evaluated by spectrophotometric analysis. The results showed that oxidase activity was increased two- to threefold in all variants, while some exhibited decreased catalase activity. The D224A variant gave the best results as it showed approximately 2-fold increase in oxidase activity without loss of catalase activity (about 92% of the wild-type catalase activity was retained). Thus, a protein variant with improved properties was successfully produced.
Policy implementation without evidence: a multi methods study of emergency admission risk stratification in primary care
Authors:   , Kingston Mark R.
Published: May 2024

Despite an uncertain evidence base, emergency admission risk stratification tools have been widely promoted in the NHS. These tools are underpinned by algorithmic models using routine health data to calculate one year admission risk for all patients in a health community (typically a general practice). The tools allow practitioners to identify at-risk individuals to target for preventative care, with the ambition to improve care, and reduce admissions/costs. This study explored why, how and to what extent emergency admission risk stratification tools were introduced in UK primary care, and stakeholder views. I undertook a multi-methods study incorporating systematic literature review; survey of 171 primary care commissioning organisations; follow-on interviews with a sample of commissioners (n=20); a user experience study of tool users (n=29) and a focus group with patients (n=9). The review found that although accuracy of the tools had been addressed, there was little underpinning evidence of effectiveness. Nonetheless, the survey confirmed largescale implementation across the UK; 86.5% of organisations had introduced a tool to general practice. Research evidence had little influence over decisions to implement, but the desire to align with policy recommendations was apparent. Interviews confirmed a complex landscape of tool introduction and use, but often as short-term pilots with few incorporating robust evaluation. I found that implementation challenges were prominent, including a lack of clarity over models of care for identified patients. Most tool users found them acceptable, were willing to use them (often on a trial basis) but reported usability and capacity issues. Patients saw opportunities for admission risk to be communicated in patient/clinician discussions, but I found no evidence that this approach was widespread.I conclude that the promotion and use of the tools was driven by optimism rather than evidence, and there remains a need to better integrate research, policy, and practice.

Published: May 2024

Drought stresses are foremost threat to plant growth, productivity as well as sustainability towards agriculture through worldwide. Some of the classical breeding approaches have been attempted to develop crop performance towards stress without significant success and so therefore, recently genetic engineering in crop plants is recognized as an alternative strategy to generate drought tolerant crop plants. Various integrated biological approaches have been undertaken to overcome such drought hurdles in achieving the full potentiality of the plant growth and production as well as improving the drought tolerance in different field crops. Some approaches are commonly used to identify genes related to drought tolerance and genes to be identified which are involved in processes known to be critical for drought tolerance; whose expression is regulated by drought stress and that consists in the identification of drought tolerance determinants based on functionality. Plant researchers have developed several spurts of biological novel ‘Omics’ technologies viz. genomics, transcriptomics, proteomics and metabolomics etc to engineer plant stress tolerance. In this review, an attempt has been made to summarize the current information based on recent literature towards recent understanding as well as latest advancement related to the adverse effect of plant under drought and their adaptations or tolerance towards such abiotic stress with a focus on the identification of drought tolerance mechanisms by soil management practices, crop establishment and exogenous application of growth regulators by regulating an appropriate level of water due to osmotic adjustment and stomatal performance etc at an integrated biological level of approach.
Performance of Guava Stem Cutting – A Review of Successful Though Non-commercial Propagation Method
Authors: Joshi C. J.
Published: May 2024

Propagation of Guava (Psidium guajava L.) can be successfully performed by stem cutting as demonstrated by many researchers time to time. Though, guava is found hard to root, use of root inducing hormone (IBA, IAA, NAA etc.), rejuvenating techniques (fungicide, wounding, Girdling etc.), growth supporting media (silt, Sand, cocopeat, vermicompost, vermiculite etc.) and suitable protected environment (mist house, polyhouse, net house etc.) ease the rooting of cutting. Despite of the fact that propagation through cutting is easiest and most convenient method of vegetative propagation to regenerate numerous planting materials in short duration, wedge grafting is still recommended as commercial method of propagation in Guava. This scenario raises the question on potentiality of stem cutting as viable propagation method. This might be due to complex mechanism behind guava stem cutting propagation which results in inconsistent and highly variable results. Moreover, propagation involves multiple factors which have combined influence on the performance of stem cutting viz., preparation of cutting, preconditioning treatment, season of taking cutting, type of cutting, chemical treatment, growing environment, growing media and container. Therefore, to establish guava stem cutting as viable and commercial propagation technique, in depth study of these factors is vital. This paper briefly discusses the research so far has done with relevance to various factors influencing performance of guava stem cutting while indicating possible future research directions for more encouraging and consistent results.

Authors: Subba Susmita , Honnurappa Shivanna
Published: May 2024

A study conducted during August, 2019- February, 2020 forty year old clonal teak plantation in Manchikere, Karnataka, showed substantial carbon sequestration potential across eight distinct clones, emphasizing the promising role of genetic diversity in enhancing carbon capture. The clone studied were MyHaD1, MyHaD4, MyHaV1, MyHaV3, MyHaK2, MySA1, MyHuT1and MyMK3.The recognition and propagation of superior clones are crucial for enhancing carbon sequestration, aiding in the absorption and storage of atmospheric carbon dioxide.The diverse performance observed among the eight clones in the clonal teak plantation underscores the critical role of genetic diversity in shaping key parameters such as girth at breast height, volume, and biomass accumulation. Measurements of volume, aboveground biomass (AGB), belowground biomass (BGB), and soil carbon stock, along with nitrogen (N), phosphorus (P), and potassium (K) levels, were conducted. Carbon sequestration potential per tree varied, with all individuals contributing 395.56 t ha-1. MySA1 showed the highest potential (3.85 t), followed by MyHaD4 (3.08 t), and MyHaV1 recorded the least (1.46 t). Soil analysis revealed available N, P, and K concentrations, and the total carbon sequestration rate was 69.55 tha-1. The organic carbon (OC) content was 1.98% and 1.61%. This emphasizes the importance of factoring in both genetic diversity and soil nutrient dynamics to optimize carbon management in teak plantations effectively.

Published: May 2024

The development of the infrastructure of the international transport corridor (ITC) “North – South” is considered, changes in the tonnage of the marine fleet due to an increase in the number of cargo shipments along the ITC “North – South” are analyzed. As a result of the beginning of EU sanctions against Russia, namely the ban on the import of many goods into Russia, as well as limits on the transportation of goods along European highways and the ban on Russian ships entering and parking at ports, measures are being taken at the level of the Government of the Russian Federation aimed at developing transport logistics focused on the south. These measures are aimed at expanding the volume of cargo transportation: both domestic and international. The “North – South” route starts from St. Petersburg and ends at the port of Mumbai (India). It is an alternative route passing through the Suez Canal. The problem of the functioning of railway communication between Iran and Azerbaijan within the framework of the “North – South” transport corridor is considered. The structure of trade turnover of the countries participating in this corridor is shown, it is noted that the corridor has a beneficial effect on the economy of the Astrakhan region. The bottlenecks of this corridor and ways to eliminate these barriers are outlined. The corridor is not only an economic prerogative of the state, but also a strategic direction. Prospects for increasing cargo traffic have been identified, cargo transportation along the “North – South” MTC in 2023 amounted to 17.6 million tons. The data of the Ministry of Transport of the Russian Federation are presented, which assess the positive growth of cargo traffic along this corridor to 41 million tons by 2030. Conclusions are drawn about the prospects for Russia to further develop the transport corridor, which in the future will become one of the main trade routes in the country.

Enhancing toxicity of pyrethroids by oxidase and esterase inhibitors in Spodoptera littoralis (Boisd.) larvae
Authors: Ismail Seham Mansour
Published: May 2024

Although pyrethroids are increasingly being used to control a number of agricultural insect pests, especially the cotton leafworm, Spodoptera littoralis (Boisd.), pyrethroid resistance is a major obstacle limiting effective control. With the aim of maintaining the effectiveness of pyrethroids in managing pests, a study was undertaken to evaluated the effectiveness of oxidase and esterase inhibitors for synergizing pyrethroids in S. littoralis larvae. Compared with the insecticide-susceptible strain (L-SS) of S. littoralis, the resistance ratio (RR) in the field population (F-RS) was 271.43–fold to cypermethrin. The use of profenofos as an esterase inhibitor significantly increased larval susceptibility to cypermethrin in the F-RS strain, with a synergy ratio (SR) of up to 192.57–fold. Significant inhibition of esterase by profenofos in the F-RS strain was found in vivo. Also, piperonyl butoxide (PB) as an oxidase inhibitor had slight effect of cypermethrin toxicity, so its addition is not a solution for pyrethroid resistance. Thus, modifying the toxicity of cypermethrin by mixing it with organophosphorus compounds (OPs) increased its toxicity and decreased the population of S. littoralis, which is a successful strategy for managing pyrethroid resistance.

Background

Breast cancer is a growing concern in Iraq, posing significant health challenges for Iraqi women. The objective of this study was to describe the demographic and clinical characteristics associated with breast cancer among Iraqi women, with a specific focus on age-related differences.

Materials and Methods

Medical records of 500 female patients diagnosed with breast cancer between 2017 and 2022 were retrospectively analyzed. Demographic information, clinical history, presentation details, treatment modalities, and outcomes were collected and analyzed.

Results

Among the studied cohort, 62.4% of breast cancer cases were diagnosed in women aged 50 and older. Marital status correlated significantly with age, with 89.9% of those diagnosed before 50 being married compared to 74.7% of those diagnosed after 50. Notably, 48% of patients diagnosed before 50 had breastfeeding duration of 1–3 months, contrasting with 28.5% of those diagnosed after 50. Diabetes mellitus, hypertension, hypercholesterolemia, heart disease, and vitamin D deficiency were significantly more prevalent among patients diagnosed after 50. Clinical presentation revealed 67.8% with tumor stage II. Metastasis to lymph nodes occurred in approximately 50% of patients. Among patients who were diagnosed after 50 years of age, 34% had metastasis, compared to 22.9% of those diagnosed before the age of 50. Mortality rates were higher in patients diagnosed after 50 (23%) compared to those under 50 (12.8%).

Conclusion

The findings emphasize the need for targeted public health campaigns, early detection initiatives, and treatment optimization to improve patient outcomes and mitigate the burden of breast cancer.
A A Case Study: Tourism Impact on the Inhabitants of Lake Sandoval – Tambopata National Reserve – Peru
Authors: Arévalo Johanna Elena Santa Cruz
Published: May 2024

Purpose: This study analyzes the impact of tourism on the inhabitants of Lake Sandoval in the Tambopata National Reserve – Peru.
 
Theoretical Background: Developing tourism in Sandoval Lake is framed under the nature-based tourism, ecotourism and Community-based tourism, where the villagers are the main human resource to develop tourism activities, taking advantage of the scenic beauty of Sandoval Lake.
 
Method: Applying a qualitative case study approach that followed a qualitative route and approach, through judgmental sampling, an in-depth interview was applied to all the entrepreneurs whose business is located around Sandoval Lake.
 
Results and Conclusion: The villagers have developed businesses that offer tourist services such as lodging, restaurants and rain transportation, considering that they all descend from the same marriage, they perceive tourism as a main economic activity that allows them to improve their quality of life, contribute to the household economy and conserve the area.
 
Implications of the Research:  The study suggests that local managers should have greater communication with the villagers to develop effective management, this relationship will allow opening spaces for research in similar areas.
 
Originality/Value: This study contributes to the literature on the impact of tourism in natural protected areas, especially in Lake Sandoval, considering that there is scarce literature on the area and even more so, given that the local people perceive tourism as a positive economic alternative in a region where illegal mining is prevalent and destroys the Amazonian forests. The relevance and value of this research is evidenced by the fact that it is the first research that directly investigates the impact of tourism as a main economic activity.

Background: The global economy faced increased instability due to the simultaneous occurrence of two major events, the global pandemic in 2020 and the Russian-Ukrainian conflict in 2022, which impacted the financial markets.
 
Purpose: This paper aimed to evaluate the comovements between the USA (S&P 500), Germany (DAX 30), France (CAC40), Japan (Nikkei 225), Canada (TSX), Russia (MOEX) and Ukraine (PFTS) stock markets and the cryptocurrencies Bitcoin (BTC), Ethereum (ETH), Litcoin (LTC) Dash (DASH/USD), Ripple (XRP) DigiByte (DGB) and Nem (XEM), from February 24, 2022, to April 12, 2023
 
Methods: The approach to our research question will involve using the causality econometric model, Granger SVAR (Vector Autoregressive).
 
Results: The results showed that stock indices and digital currencies show sharp structural breaks, and not all markets influence cryptocurrencies. The MOEX stock market affects the price formation of BTC, ETH, DGB, XEM, and XRP, while the DAX 30 stock index impacts ETH, LTC, DASH, DGB, and XEM. The Ukraine market (PFTS) influences ETH, but the other stock markets do not influence any of the cryptocurrencies analysed.
 
Conclusion: Investors, policymakers, and other participants operating in the digital currency markets can find valuable information in the study's conclusions when seeking to rebalance their portfolios.
Productivity of Açai Euterpe Precatoria and Production System Management Recommendations in the South Of The Amazonas

Published: May 2024

Objective: To investigate the productivity of the Amazon açaí Euterpe precatoria Mart in order to support recommendations for adapting management to increase productivity in the production system in southern Amazonas.
 
Theoretical Framework: The demand for açaí justifies its domestication to increase productivity in addition to extractive production. In this context, difficulties arise due to the lack of knowledge about managing the species, which is required along with its domestication. Thus, knowledge that supports the supply of soil and nutritional conditions is required for E. precatoria, which is still little studied in terms of management.
 
Method: The productivity assessment was carried out in an experiment whose ages of açaí groves planted side by side, 8, 9, 10 and 12 years old, constituted treatments. For each açaí grove age, randomized by the producer in the planning, 4 experimental plots were designed containing 3 trees spaced 3.0 m x 3.0 m, with 4 replications, totaling 16 experimental plots in randomized blocks.
 
Results and Discussion: The results indicate the need to manage soil fertility to increase the productivity of açaí groves, which are obtained in conditions of low soil fertility, even for the 12-year-old açaí grove, selected as the most productive.
 
Research Implications: This study presents practical and theoretical implications for the açaí palm in Amazonas, whose management is still in its infancy. It identifies low productivity of açaí groves and the need to insert nutrients not only through alternative practices with low economic and environmental impact.
 
Originality/Value: This study contributes to the basis of future studies on the agricultural management of the Amazon açaí tree as a cultivable species.

A água é essencial à sobrevivência de todas as formas de vida devido à sua presença em diversos processos físicos, químicos e biológicos, além de necessária a múltiplas atividades antrópicas, tais como abastecimento, usos agroindustriais, geração de energia elétrica, turismo, lazer, pesca, entre outros. Com este estudo, objetivou-se verificar, por meio do Índice de Qualidade de Água (IQA), a interferência das atividades antrópicas na qualidade das águas do córrego Sampaio, localizadas no perímetro urbano do município de Pires do Rio – GO. Os resultados indicaram que as amostras coletadas apresentam “boa” qualidade, exceto os pontos que fazem parte da Estação de Tratamento de Esgoto, que apresenta qualidade “péssima”. Ao considerar, entretanto, os resultados obtidos das análises microbiológicas, os valores de coliformes termotolerantes, evidenciam uma alta contaminação de origem fecal, inviabilizando o consumo “in natura”.
