Control networks are critical offices that have to be exceptionally solid and productive. Finding issues in these frameworks is exceptionally imperative for keeping them steady, keeping gear from breaking, and maintaining a strategic distance from long power blackouts. It has gotten to be clear that scientific modeling may be a awesome way to think about and discover issues in control frameworks. Taking after this strategy requires making a scientific show of the control framework, which incorporates motors, transformers, transmission lines, and loads. A few physical laws, like Ohm's Law and Kirchhoff's laws, are frequently utilized within the models to accurately show how electrical circuits work when they are working legitimately and when they aren't. On the off chance that you need to discover issues, you'll utilize numerical models to form flaws like brief circuits, open circuits, and ground deficiencies appear genuine. Through examining how the framework responds to these fake issues, engineers can make programs that can discover genuine flaws and tell where they are when they happen. These calculations frequently utilize strategies like evaluating the state, evaluating the parameters, and recognizing designs. Utilizing real-time information to figure the current state of the framework is what state estimation is all approximately. On the other hand, parameter estimation is all almost finding changes in framework parameters that might cruel there is a problem.

Published: September 2024

Let h_1, h_2 be two analytic functions defined in the open unit disc Δ:={z∈C:|z|<1} which are normalized by the condition h_1 (0)=1=h_2 (0). Then h_1 is P-stable with respect to h_2, whenever (P_n (h_1,z))/(h_1 (z))≺1/(h_2 (z))       (z∈Δ),holds for all n∈N. Here ’≺’ stands for subordination and P_n (h,z)=P_n (z)*h(z) where P_n (z) denote the n-degree polynomial induced by the (n+1)th row entities in an admissible lower triangular matrix. The main purpose of this article is to prove that the function ((Az+1)/(Bz+1))^δ is P-stable with respect to (Bz+1)^(-δ), for δ∈(0,1] and -1≤B<A≤0 but not P-stable with respect to itself, when -1≤B<A<0 and δ∈(0,1]. As an application, considered different admissible lower triangular matrices to derive various results related on stability.

Message encryption is a process of protection of the original data in transmission. Several cryptosystems were designed in the history for different environments. Public key or Asymmetric cryptosystem has become more popular in recent era where the key space consists both public and private keys. Elliptic curve cryptography dominates public key cryptosystems like Diffie Hellman key exchange and RSA. ECC is more powerful and alternative technique of RSA, with a simple replacement of exponent calculations of large prime numbers to mathematical representation of Elliptic curve points. Besides the computation ECC works with shorter key length than RSA. The present paper describes an encryption algorithm using elliptic curves over finite fields. Here a group of authentic users transmit.
Nonlinear Analysis of EDF Scheduling Framework for Resource Distribution in Cloud Computing
Authors: Neelima Priyanka Nutulapati
Published: September 2024

In modern times, the field of information technology is significantly shifting towards cloud computing. This innovative technology involves the permanent storage of resources on servers, which clients access via the internet. Typically, a cloud comprises a collection of resources known as virtual machines, capable of managing both computational tasks and storage needs. As the demand for cloud services continues to rise, the scheduling of these resources presents a considerable challenge. Scheduling refers to the workflow management necessary to complete tasks within the system. An efficient scheduler adapts its scheduling policy dynamically in response to changing conditions and task requirements. Cloud computing represents a recently developed technology where resources, whether physical or virtual machines, are permanently stored on servers and accessed by users through the internet. The cloud offers various service models, including Platform as a Service (PaaS), Software as a Service (SaaS), and Infrastructure as a Service (IaaS). In this context, IaaS refers to a set of resources, including virtual machines, that provide computational and storage services. Given the increasing adoption of cloud technology, resource scheduling has become a critical task. Hence, optimizing the scheduling of requests to ensure the best utilization of cloud resources is essential. This paper introduces a Nonlinear Analysis of EDF Scheduling Framework for resource allocation that considers deadlines and processing times when assigning resources to specific jobs. The performance metrics, including Average Turnaround Time, Average Waiting Time, and Average Deadline Violation, show a significant improvement when compared to traditional scheduling models such as First-Come, First-Served (FCFS), the Shortest Job First (SJF), and Simple Earliest Deadline First (EDF) models.
Using Artificial Neural Networks to Predict Leakage Location in Water Distribution Networks
Authors: Parisa kolyaee
Published: September 2024

One of the major types of water wastage in a distribution network is the leakage that occurs in pipes or other network components such as connections. Leaks in urban water supply networks impose many costs and workforce on governments and related organizations annually. If the cause of leakage is traced to the cracks and slits on various parts of a network, the amount of leakage from the location of the crack is said to be directly associated with the amount of pressure at that point. To trace leakage in water distribution networks, this study introduced a method based on hydraulics modeling and the inverse solution of flow equations to predict the location and amount of leakage in water distribution networks, by considering the values of the measured pressure in some network nodes. For this, a hydraulic model of the network under study was provided in the EPANET Hydraulic Analysis software, and the network analysis of various values and states of hypothetical leaks led to obtaining pressure values in the different nodes of the network via modeling water modeling under a steady state. Then, the artificial neural network, having been trained, was used to provide measured pressures in some network nodes at the testing hour as input data to the neural network to locate possible leaks in the water distribution network and to predict their approximate values. The findings were found to enjoy desirable accuracy.

GIS-Driven Method for Site Feasibility Assessment of Large-Scale Solar Thermal Seawater Desalination: An Australian Case Study
Authors: Huang Yingfei , Omar Amr , Saldivia David , Taylor Robert A. , Leslie Greg
Published: September 2024

Concentrated solar power (CSP) plants can be coupled with seawater desalination via Multi-Effect Distillation (MED) by recovering the cycle’s ‘free’ waste heat. However, project viability, based on the payback period, is contingent upon systematic consideration of climate variability, topography, water resources, markets, and natural hazards. This study describes a data-driven method for screening and then selecting optimal sites in Australia by integrating a Geographic Information System (GIS), System Advisor Model (SAM), MATLAB program, and a Multi-Criteria Decision-Making (MCDM) model. Results for potential sites based on only climate, topography, water resources, markets, and infrastructure identify approximately 2.13×105 km2 of land are suitable, granularly mainly located in the north-west and the south coastal regions with high solar resources (average direct normal irradiance (DNI) > 6 ). These regions encompass 56,000 km2 and 25,100 km2 of suitable areas, respectively, with potential payback periods as low as 12.2 years and 14.0 years. Queensland's northern coastal regions also show promise with a potential payback period of 13.4 years, but the suitable area is only 2,070 km2 due to the marine protection areas in the eastern coastal zone. New South Wales faces hurdles due to topography and lower solar resources. Model results were consistent with the development of CSP installations in Australia, particularly, the Aurora facility in South Australia. This study provides a precise delineation of CSP-MED integration regions in Australia through the multi-dimensional analysis, offering insights into payback periods, and quantifying variable impacts on project geographical, technical, and economic feasibility.
A Sensitivity Analysis of the High-Temperature Solar Pretreatment of Calcite-Rich Manganese Ores
Authors: Hockaday Lina
Published: September 2024

The modelling of high-temperature direct solar thermal treatment of manganese ores found that a heliostat field and tower process rated at 2.5 MWth will treat roughly ten thousand tons of material annually, producing calcined products of consistent grade. This paper looks at a sensitivity analysis of the results when changing the solar irradiance and financial parameters. The sensitivity analysis shows that a 10% decrease in solar irradiance increases the levelised cost of heat by 5% while decreasing the production by 5%. The levelised cost of heat (LCOH) was most influenced by the cost of the heliostat field as the largest component of capital expenditure. Changes in the interest rate also have a significant impact on the levelised costs of the pretreatment.

Authors: Mojeed Omotayo Adelodun  , Evangel Chinyere Anyanwu
Published: September 2024

Radiation use in medical imaging, while essential for accurate diagnosis and treatment planning, poses inherent risks that require comprehensive risk management and safety strategies. This review discusses the critical aspects of managing these risks in clinical settings, focusing on patient safety, staff protection, and environmental considerations. A major challenge in medical imaging is balancing the diagnostic benefits of radiation against potential harms, particularly in sensitive populations such as children and pregnant women. Comprehensive risk management involves implementing dose optimization techniques, such as using low-dose imaging protocols and advanced technologies like iterative reconstruction and artificial intelligence (AI) algorithms, which enhance image quality while minimizing exposure. Additionally, ensuring the safety of healthcare staff is paramount. This requires adherence to strict safety protocols, including the use of personal protective equipment (PPE), regular monitoring of radiation levels, and continuous education on safe radiation practices. Institutional policies must also address the proper maintenance and calibration of imaging equipment to prevent unnecessary exposure due to equipment malfunction or improper use. Environmental safety is another critical component, necessitating the safe disposal of radioactive materials and the adoption of energy-efficient technologies to reduce the environmental footprint of medical imaging. Regulatory compliance with international safety standards, such as those set by the International Commission on Radiological Protection (ICRP) and national bodies, is essential for ensuring consistent safety practices across healthcare institutions. Future directions in radiation safety include the integration of digital health technologies to monitor and manage radiation exposure more effectively, and ongoing research into novel imaging techniques that could further reduce radiation risks. Collaboration between healthcare providers, researchers, and policymakers is crucial to advancing safety standards and improving risk management strategies in medical imaging. This review highlights the importance of a comprehensive approach to managing radiation risks in medical imaging, emphasizing the need for continuous innovation, education, and policy support to protect patients, healthcare workers, and the environment.

Published: September 2024

O objetivo dessa revisão foi avaliar desfechos clínicos e centrados nos pacientes em relação a espessura dos enxertos de tecido conjuntivo subepitelial (ETCS) utilizado nas cirurgias de recobrimento radicular em recessões gengivais (RG) unitárias e múltiplas. Foi realizada busca na literatura visando responder à pergunta (PICO): em pacientes que receberam retalho posicionado coronalmente+ETCS em RGs classe I e II de Miller, a espessura do enxerto tem influência nos desfechos avaliados? Foram consultadas as principais bases de dados PubMed, Scopus e ISI Web of Knowledge, incluindo estudos dos últimos 20 anos. Os selecionados foram submetidos aos critérios de inclusão e exclusão e 26 artigos foram incluídos (16 RG unitárias/10 múltiplas), 258 excluídos após busca manual, por não apresentarem a espessura do enxerto utilizado. Os estudos foram divididos em enxertos delgados ≤ 1 mm e espessos ≥ 1 mm de espessura. A porcentagem média de recobrimento radicular (Rec Rad) com enxertos delgados foi 79.53/93.44 (unitárias: 4 estudos /múltiplas: 7 estudos), já com espessos 76.18: 11 estudos/ 83.12: 3 estudos. Um estudo avaliou os desfechos centrados em pacientes, os enxertos delgados foram considerados mais estéticos e com menor morbidade. É possível concluir com base nos estudos atuais que não há diferença na taxa de Rec Rad (em RG unitárias ou múltiplas) entre enxertos delgados ou espessos, porém para evitar o sobre tratamento e utilizando os desfechos centrados no paciente, enxertos delgados (< 1 mm) promoveram menor morbidade no sítio doador e não alteram a taxa de recobrimento radicular.

Published: September 2024

Objetivo:  O objetivo desta revisão de literatura é descrever as etapas fundamentais do processamento tecidual para microscopia óptica com coloração de hematoxilina e eosina (HE) de interesse na odontologia. Revisão de Literatura: O processamento tecidual para coloração com HE é constituída basicamente por 7 etapas sequenciais. Imediatamente após a biópsia, o espécime é fixado em formol a fim de interromper a autólise tecidual. Em seguida, na etapa de clivagem, a peça sofre redução de tamanho para facilitar a penetração do agente fixador. Caso a amostra seja dente ou tecido ósseo, ela passa por um processo de descalcificação prévio à clivagem. Nas etapas de processamento e inclusão ocorre remoção de líquidos do interior das células para que em seu lugar entre parafina, e o tecido é incluido em um molde para formar um bloco rígido de parafina, o qual será cortado na fase de microtomia. Finas secções teciduais são então aderidas a uma lâmina, coloridas e seladas. Conclusão: Um ótimo resultado na obtenção de lâminas histológicas depende da execução correta de todas as etapas do processamento tecidual, sendo também influenciado pelos cuidados do cirurgião-dentista com a amostra a ser enviada ao laboratório.

Published: September 2024

Objetivo: O objetivo desta revisão de literatura é descrever as características relevantes das lesões reativas (proliferações não-neoplásicas) mais prevalentes na cavidade oral. Revisão de Literatura: as lesões reativas são aumentos de volume benignos decorrentes de um trauma crônico e de baixa intensidade que provoca uma resposta tecidual exuberante no tecido conjuntivo, onde um processo inflamatório induz a proliferação de fibroblastos e fibras colágenas. A hiperplasia fibrosa inflamatória, o granuloma piogênico, a lesão periférica de células gigantes, o fibroma ossificante periférico, o fibroma de células gigantes e o neuroma traumático são lesões com características histopatológicas específicas, mas com aspecto clínico similar. Seu tratamento é realizado por meio de remoção cirúrgica, sendo essencial a eliminação dos fatores irritativos para não ocorrer a recidiva. Conclusão: As lesões reativas são de natureza benigna, sendo fundamental o seu conhecimento por parte do cirurgião-dentista, uma vez que essas lesões são muito prevalentes e, em alguns casos, são clinicamente similares a neoplasias.

Published: September 2024

A leucemia caracteriza-se pela proliferação descontrolada de células originárias de uma mutação hematopoiética. Sua malignidade pode ser classificada de acordo com a linhagem celular, mieloide ou linfoide, e o modo de evolução, aguda ou crônica. As manifestações bucais podem ser os primeiros sinais em um paciente acometido por leucemia aguda, e são de suma importância para se obter o diagnóstico precoce. Foi realizado uma busca de artigos nas bases de dados, Scielo, Pubmed e Biblioteca Virtual de Saúde- BVS, entre os anos 2011 e 2024, utilizando os descritores “Acute myeloblastic leukemia”, “gingival”, “leukemia”, “Hemorrhage”. Foram levantados 70 artigos, e selecionados 30 artigos nos idiomas inglês, português e espanhol, sendo excluídos os estudos que tratavam sobre leucemia crônica e outras neoplasias que não se relacionavam com o tema. Dentre as manifestações bucais mais comuns pode-se citar o aumento gengival, úlceras orais, sangramento gengival espontâneo, petéquias, mucosa pálida, infecções virais e fúngicas. O infiltrado leucêmico se estende ao tecido gengival, causando aumento da espessura gengival e à formação de pseudobolsas periodontais, resultando em infiltração inflamatória secundária. Sendo assim, concluiu-se que para definir um diagnóstico preciso e precoce o cirurgião-dentista deve reconhecer essas alterações bucais, haja vista que podem ser um dos  dos primeiros sinais da patologia; para, assim, compor uma equipe multidisciplinar a cuidar do paciente e garantir um melhor prognóstico.

Published: September 2024

This study explores how leadership styles, particularly the principal’s approach, influence organisational effectiveness in secondary schools, arguing that structured and supportive leadership fosters committee effectiveness, while laissez-faire or free-reign leadership may undermine collaboration, motivation, and decision-making, ultimately impacting school performance. A quantitative descriptive research design approach was employed. The study used a multistage sampling technique to select 313 participants from secondary schools in Zamfara State, Nigeria. The data collected was analysed using percentage and linear multiple regression analysis to test the hypotheses formulated at a 0.05 significance level. It was found that leadership styles (participatory and free-reign) had a significant negative relationship with the committee system effectiveness, while directive leadership style and committee system effectiveness did not have a significant relationship. Policymakers and educational authorities should address the resource constraints that limit the availability of welfare and feeding committees. School leaders should also adopt balanced management styles that incorporate clear directives and controls while allowing some level of participation and flexibility to foster a positive and effective committee system.

Authors:   Cavite State University, Lumbog St. Joseph , Gaspar Maricel ,   First Asia Institute of Technology and Humanities
Published: September 2024

Conventional account credentials that include a password are becoming obsolete due to their limitations and susceptibility to cyber threats. This demands using alternative authentication methods that eliminate the risks of breaches and phishing. This paper discusses the integration of passwordless authentication into an electronic document management system (EDMS). The authentication method used in the system utilizes a Time-Based One-Time Password (TOTP), which operates security keys in the form of one-time passwords (OTP) that are sent to the users via email, short message service (SMS), or mobile application. The TOTP algorithm is used in the system, allowing time value as a moving factor. The Rapid Application Development (RAD) model was used in the system development and ISO 25010 was used in the evaluation. The sample size of the respondents for the acceptance testing was determined using Krejcie and Morgan’s formula. The research sample involves 10 information technology experts, one on-the-job training (OJT) coordinator, three OJT advisers, and 244 OJT students. Based on the results, the system was rated outstanding (system evaluation=4.66; acceptance evaluation=4.34), implying that the system met its requirements and that passwordless authentication was proven to increase the security of the developed system. This outcome serves as the basis for integrating passwordless authentication into various systems.

It is characterized by continuous intraluminal growth of benign smooth muscle tumor cells along with the uterine vein to the pelvic and abdominal venous systems, including the iliac vein and inferior vena cava, and even to the right atrium of the heart and pulmonary artery, leading to life-threatening complications. This case report describes a 43-year-old female patient with IVL who underwent four myomectomy surgeries.

Case Report: A 43-year-old female patient with rare IVL was admitted after four myomectomy surgeries. After preoperative evaluation by color Doppler ultrasound, cardiac ultrasound, chest and abdominal computed tomography (CT) scans, this patient underwent total hysterectomy, bilateral salpingectomy, and complete resection of the entire intravascular leiomyoma. This article discusses the characteristics, diagnosis, treatment, and especially surgical precautions of IVL. In addition to surgical resection, this article also discusses other treatment options for IVL.

Conclusion: Intravascular leiomyomatosis has unique biological characteristics and clinical manifestations. Through accurate diagnosis and timely complete tumor resection, as well as regular follow-up after surgery, most IVL patients can achieve good long-term prognosis and quality of life. However, further research is needed on the etiology and pathogenesis of IVL.

ABSTRACT
Nowadays there is evidence that animals are exposed to microplastics (MPs) via food, however there is not much known about their effect on tissue of gastrointestinal tract and on gut microbiome. In this study, adult male rats were fed with polyethylene MPs, mixed with standard pellet food for 24 days at different concentrations ranging from 0 to 1000 μg/day. At the end of experiment, rats were euthanized and histopathological investigation using light and electron microscopy and the gut microbiome was analyzed using MiSeq 16S rRNA amplicon sequencing. Microscopic analysis revealed significant impact of MPs on the intestine, including visible changes to the crypt area as well as reduction in mucus secretion. Autophagic vacuoles were observed in the livers of the rats fed with MPs at 100 µg/day. Oxidative stress was evident in rats fed with 1000 µg/day of  MPs,  as indicated by the presence of myeloid bodies in both intestinal and hepatic cells. The gut microbiome was also affected by MPs. Although, no distinct clusters were formed when the bacterial communities in the different treatments were ordinated by multidimensional scaling (NMDS), the diversity indices including operational taxonomic unit (OTU) richness and Chao1 exhibited an increasing trend with increasing MPs concentration. Pearson correlations revealed a linear increase in the relative sequence abundance of Clostridia (R=0.036, P=0.003) with increasing MPs concentration, but not in the case of other bacterial groups,. Lactobacillus faecis was the most abundant OTU in the entire dataset, and its relative abundance decreased significantly with increasing MPs concentration.  We conclude that exposure to MPs can disrupt cellular function and disturb microbiome balance, and in the event of prolonged exposure, organisms might experience unpredictable effects.

In this study, the potential antimutagenic/cytoprotective effect of the oil extract (2.5µg/ml) from Anethum graveolens L. (Dill) on oxidative DNA damage was tested. The experiments were carried out to inhibit mutagenicity induced by potassium bromated (KBrO3-9g/l) in Allium assay using mitotic activities and nuclear DNA contents. Result showed a clear reduction in radical length in all KBrO3-treated groups compared to control plants. Mitotic activity, measured by mitotic index (MI) and mitotic stages, were significantly decreased in meristematic cells after KBrO3 application, The results showed that mitotic index (MI) was decreased to reach about 0.8 at 24 hrs compared with 23.9% in untreated plants. The analysis of potential cyto and genoprotective of dill extract on nuclear DNA contents showed a statistically significant increase in the nuclear DNA content compared to KBrO3-treated roots was observed. Clearly, dill oil showed highly performance in protecting the mitotic cells against mutagenic KBrO3 effects by increasing the MI and decreasing the abnormal chromosomes. Also, the percentage of damage reduction was observed in the pre- (28.9, 57.9 and 46.4 %), simultaneous (53.0, 70.6 and  35.7 %) and post- (37.3, 61.8 and 50 %) treatment. The results of the qualitative study showed that this dill extracts were rich in chemical compounds belonging to several phytochemical classes. GC-MS analysis detected 29 chemical compounds with different concentrations. The predominant ones were Octadecanoic acid (31.75%) and 2-pentanone, 4-hydroxy-4-methyl (16.77). So that these experiments will help to understand and uncover the mechanism of action dill oil against the mutagenic effects of KBrO3 (i.e whether they have a prophylactic or treatment activity).

The present research investigates the pivotal function of healthcare assistants in providing assistance to individuals with mental health conditions in forensic environments. Health care assistants provide crucial assistance, facilitating patients in carrying out their everyday activities and enhancing their general well-being. Notwithstanding their substantial contributions, healthcare assistants often encounter difficulties associated with insufficient training and exposure to high-pressure circumstances, such as aggression and mental anguish. Therefore, it is crucial to comprehend their experiences, decision-making processes, and support requirements in order to improve their efficacy and well-being. Furthermore, it examines the consequences of these constraints on the safety of patients and the quality of treatment. The objective of this research is to identify areas for improvement in training and support systems by examining current literature and investigating the perspectives of HCAs. The results will help in the development of techniques that improve the proficiency and self-assurance of Health Care Assistants (HCAs), thereby helping both staff members and patients in forensic mental health settings.

The network project titled “Nordic animal gene banks – added value through Nordic cooperation” (NordFrost), has aimed to strengthen the collaboration and competence for ex-situ conservation of animal genetic resources (AnGR) in the Nordic region. This project was launched as a case study following the Horizon2020 funded IMAGE project (2016-2020) where it was concluded that there is a broad variation in the current state of practices and the distribution of responsibilities related to cryoconservation activities between the Nordic countries. The national strategies on conserving AnGR emphasise ex-situ conservation in varying degrees. However, collection of samples, metadata, back-up storage of material or common strategies and action plans for ex-situ conservation on a regional level does not exist. This makes conservation of AnGR an exposed area that threatens the resilience of Nordic food security. By developing new collaborative models, strengthening Nordic infrastructure, and enhancing the development of Nordic strategies for ex-situ conservation in the region, this network will contribute to increased sustainability for populations and future Nordic food security.
Uncommon Ethical Initiatives Nurses May Want to Consider When Value Conflicts Arise

Published: September 2024

A most excruciating situation for particularly patients and, families arises when they and/or their providers must make end-of-life decisions, these decisions may be most difficult for staff as well because they may have wholly opposite than these parties. In this piece I present a case and three few less commonly taken but sometimes most effective approaches to this situation that staff may take and hat are the best ethical approaches possible. These are allowing all decision-makers to present not only their views but the rationales underlying them, switching the question from what the decision should be to who should decide, and providers initially telling these parties that they support them as in seeking an appeal regardless of what they themselves believe.

Silica-titania mixed oxide with catalytic and adsorption properties has been of great academic and industrial interest. Metal oxides supported on silica have been used as a matrix for immobilizing electron transfer mediators, generating materials with diverse properties. The characterization of the surface acidity of these materials is essential and has been carried out using various techniques, including IR spectroscopy and calorimetry. However, no single technique completely analyses the present acidic sites. This study used calorimetric titration to investigate a mixed oxide containing titanium and silica, prepared by the sol-gel method, and its interaction with pyridine. The results showed that thermal treatment increased the enthalpy values (ΔH), indicating water removal from the matrix surface. The presence of pyridine resulted in a decrease in ΔH values, suggesting a preferential occupation of the stronger acidic sites. After thermal treatments between 473 and 573 K, the solids exhibited similar ΔH values, indicating a homogenization of the surface acidic sites. Calorimetric analysis revealed that the acidic sites were occupied in descending order of strength, with the strongest sites being filled initially. The increase in temperature did not result in new acidic sites but rather in greater occupation of the existing ones. Correlation between calorimetric and infrared data is suggested as the next investigation step. Thus, the results of this study contribute to a deeper understanding of the physicochemical properties, especially regarding their surface acidity, with the potential for more effective and controlled practical applications of this silica-titania mixed oxide in catalysis and adsorption.
