The computational study of fixed-point problems in distance spaces is an active and important research area. The purpose of this paper is to construct a new iterative scheme in the setting of Banach space for approximating solutions of fixed-point problems. We first prove the strong convergence of the scheme for a general class of contractions under some appropriate assumptions on the domain and a parameter involved in our scheme. We then study the qualitative aspects of our scheme, such as the stability and order of convergence for the scheme. Some nonlinear problems are then considered and solved numerically by our new iterative scheme. The numerical simulations and graphical visualizations prove the high accuracy and stability of the new fixed-point scheme. Eventually, we solve a 2D nonlinear Volterra Integral Equation (VIE) via the application of our main outcome. Our results improve many related results in fixed-point iteration theory.

Comisión Nacional de Energía Atómica (CNEA) has the responsibility for restoring uranium mining facilities once the operations have finished. CNEA, within its Environmental Program and in compliance with its legal responsibilities, decides to implement a restoration project for all sites related to the mining and processing of uranium ores. The Malargüe Site is located within the Province of Mendoza in the city of Malargüe. It is the first site to successfully complete its remediation. The activities consist of relocation of tailings to an engineering repository. The tailings management (encapsulation) and rehabilitation of the area was finished in June 2017. The remediation alternative for the ore tailings was selected after conducting comparative studies and submitted the project to the society for consideration. The objective of the encapsulation of the mineral tails is to isolate them from the environment, also proceeding with the decontamination and rehabilitation of the area (landscaping, post-closure monitoring and 20 years monitoring period). Encapsulation consisted of the construction of a containment cell for the mine tailings, to isolate them and prevent pollutants from entering the environment through the transfer routes. To clean the impacted areas, the soil was removed, it was incorporated into the encapsulation, and the filling was carried out with natural soils from the area. Remediation prevents radon transfer to the environment, as 222Ra is an alpha emitter with a half-life of four days, which produces its own radioactive progeny. Radon progeny are solids, and when a 222Ra nucleus emits an alpha particle into the air, the resulting 218Po nucleus, momentarily electrically charged, adheres to any dust particle. Remediation prevents the discharge into the air containing radon and also containing dust particles charged with intensely radioactive radon progeny. The tasks mentioned make it possible to decrease radon emanation, reduce radiological risks to the public and prevent the entry of rainwater into the system. In addition, the containment system prevents the discharge of contaminated liquids into the environment, avoiding contamination of the groundwater. All these activities are according to the concepts of sustainability.

Design‐Expert software has been used to find out the perfect response through yarn properties surface methodology. Thirteen experimental runs were trailed to find the perfect result.

Abstract Background Contamination in the contact lens training area could be due to bacteria, which can lead to the major consequence of ocular infections. We aimed to investigate the contamination caused by bacteria in the contact lens training area in private optical clinics of the Udupi district, India. Methods A cross-sectional study evaluated the swabs from the contact lens container, contact lens solution tip, washing area and lens fitting area for bacterial contamination. Twenty swabs collected from different areas of five optical clinics were inoculated in Brain heart infusion broth (BHIB). The broth was streaked in MacConkey and Blood agar and incubated at standard conditions for the growth of bacteria. All isolates were identified using conventional culture methods, and Gram staining was performed. Results Twenty samples (contact lens case, n = 5; contact lens solution tip, n = 5; washing area, n = 5; cleaning towel, n = 5) from private optical clinics were recruited for the study. Bacterial growth was indicated in which lactose fermentation was seen at (15%), non-lactose fermentation at (35%), and no bacterial growth at (50%) in MacConkey agar. Partial or alpha-hemolytic (α hemolysis) was seen in (5%), complete or beta-hemolytic (β hemolysis) was seen in (40%), no hemolysis or gamma hemolysis (ϫ haemolysis), was seen in (30%), no growth was seen in (25%) on blood agar. Gram-positive cocci (45%), Gram-negative bacilli (20%), and no increase in (35%) were observed in MacConkey agar and Blood agar. Bacterial species were not identified in this study. Conclusion Contamination was found in lenses, solution tips, washing areas, and cleaning towels which might lead to ocular infections. Perception should be given to those responsible for fitting lenses.

In this paper, we apply the variational approach for solving the time-space fractal Bogoyavlenskii equation. By the two-scale fractal complex transformation, the fractal modification of Bogoyarlenskii equation is equivalently rewritten as the original Bogoyavlenskii equation. By variational principle, different type solutions including fractal bright soliton solution, fractal bright-like soliton solution, fractal kinky-bright soliton solution and fractal periodic wave solution are provided, which are not touched in the existing literature. Numerical results are presented to show the propagation behaviours.

In this paper we provide sufficient conditions for the existence as well as the uniqueness of solutions for a class of boundary value problem for fractional differential equations involving the Riemann-Liouville fractional derivative and nonlinear integral conditions. Our work will be considered by using suitable fixed point theorems. [ABSTRACT FROM AUTHOR]

Introduction: Children’s happiness is influenced by family relationships. Children’s daily interactions with their parents are now seen as a factor in their development. At the same time, the family is considered the most important field for children’s growth. The aim of the current research is to study the strategies of women who are the head of the household and non-head of the household in creating happiness in the family environment. Method: The present research method was qualitative and thematic analysis. Also, data was collected with 40 semistructured interviews in Yazd city; 20 of the sample women was non-headed and 20 were female heads of the household. Also, targeted sampling with maximum variety was done. After collecting the data, coding was done with six steps of thematic analysis.The results showed that non-custodial women experienced the three final themes of affectionate parenting, self-satisfaction and holistic femininity. Findings: Meanwhile, the female heads of the household had experienced the two final themes under the title of overall happiness and failure in happiness. As a matter of fact, female guardians try beyond their ability to meet the all-round needs of their children to create happiness in the family. According to the collected data, non-custodial women acted stronger in creating happiness in the family environment despite having a husband. But the female head of the household had to fill in the absence of the wife and sometimes she was unsuccessful in creating happiness. Discussion : It is concluded that the happiness of women and family can strengthen the morale in the family environment and subsequently promote the motivation of growth and development because happiness, as one of the dimensions of social development, is considered important to achieve the development of society.

Objective: To examine and evaluate ways in which an understanding of the quintessential element of Human Factors/ Ergonomics can address the spectrum of existential threats that confront contemporary civilization. Background: HF/E is dedicated to improving quality of life. Paradoxically, many processes which sustain contemporary civilization act to reduce that overall quality. Some technological developments themselves now even present existential threats to the fragile skein of civilization itself. Many disciplines address these diverse threats, and each may be advised and facilitated by HF/E knowledge and methods. It is a moral imperative of our science to contribute what we can to proposed resolutions. Method: A primary conduit, by the established strengths of HF/E can contribute to potential solutions is identified. The present work advocates for specific, practical interventions using a direct-perception mediated, panopticon principle, that derives from the corpus of our science. Result: Limitations upon a general, social understanding of imminent global concerns, which are largely ignorable when not actually present, are brought to immediate consciousness via an HF/E principle emphasizing the direct-perception of threat. It is argued that this, and allied HF/E insights can generate practical steps toward problem resolution at both macroscopic and localized levels of implementation. [ABSTRACT FROM AUTHOR]

At the outset of design projects, our approach typically involves receiving a brief that often presumes a solution. However, in people-centered innovation, our focus shifts from the object or product to the real-life situations and habits of individuals. This paradigm shift entails prioritizing the diverse experiences and contexts of our target audience. Our project teams embrace this perspective by delving into the actual experiences of users with the product. By understanding their desires, needs, and sensory encounters, we aim to offer solutions that resonate with their lived realities. This approach necessitates a deep dive into users' activities, aspirations, and genuine requirements. The paper's objective is to meticulously gather and address these needs, crafting design solutions that truly align with users' preferences and aspirations. [ABSTRACT FROM AUTHOR]

Even though Indonesia faces significant gender disparities across various sectors, including education, health, employment, and political representation, there remains a dearth of research addressing the barriers and strategic solutions for women's empowerment, which is the aim of this study. A quantitative method driven by the Modified Penta Helix Model (MPM) and the Delphi Analytical Network Process (DANP) was used. On the one hand, MPM was used to establish renewal between the five strategic dimensions and other additional elements such as economic, socio-cultural, and education and training. On the other hand, D-ANP developed indicators based on Focus Group Discussions (FGD) outcomes, in-depth interviews, and structured questionnaires. According to this study, education and training are essential in empowering women. The results of this study indicate the main problems in empowering women, which are divided into eight main dimensions: economic, socio-cultural, education and training, government support, association support, academic support, media support, and private sector support. Education and training were the most critical problems in empowering women. Collaboration between academics, business, community, government, and media is essential to develop effective education and training programs to empower women in Indonesia. Through employing D-ANP and MPM methodologies, this study suggests a model of women's economic empowerment to improve the quality of Indonesian women and Indonesia's position in the Women's Empowerment Index.

Introduction. A method for protecting concrete and aerated concrete by treatment with a calcium polysulfide-based solution is considered. The solution penetrates into the pores of the materials and, after drying, forms a water-repellent nanoscale layer, protecting the material from water penetration. This ultra-thin layer is formed as a result of the destruction of calcium polysulfide molecules while drying the impregnating solution and gives the material hydrophobic properties. The paper presents research results of the properties and composition of the forming protective layer and its effect on water penetration into the materials. Materials and methods. In the article authors present data on water penetration into the studied concrete and aerated concrete samples, the size and composition of the hydrophobic agent using laser and X-ray diffraction, ultraviolet spectroscopy, as well as using visual research methods, including electron microscopy. Results. It has been revealed that the hydrophobic surface is formed from a mixture of sulfur and calcium carbonate. It is shown that concrete and aerated concrete impregnated with a calcium polysulfide-based solution acquires pronounced water-repellent properties, expressed in contact angles corresponding to superhydrophobic surfaces. The presence of sulfur was established by ultraviolet spectroscopy, and force microscopy showed the formation of nanocomposite particles from sulfur and calcium compounds. X-ray phase analysis showed that the protective layer deposited on the surface of the materials consists of sulfur nanoparticles (65%), as well as nanoparticles of calcium compounds – vaterite (21%) and calcite (13%). Surface treatment of concrete with a sprayer leads to a decrease in water absorption from 5.4% to 3.1%, and in the case of treatment by immersion to a value of 1.5%, while the use of preliminary vacuuming before immersion of the samples allows achieving a water absorption parameter of 0.9%. It is shown that impregnation with preliminary vacuuming leads to water absorption values of less than 1%, which indicates the practical water impermeability of samples of full-scale products (concrete curbs and pipes). Discussion. It is noted that during surface treatment of aerated concrete with a sprayer, a chemically resistant superhydrophobic layer in the form of a nanocomposite is being formed, which penetrates to a depth of 3–3.5 cm, reliably protecting the material from water and chemical penetration. Surface treatment is effective in cases where objects (facades, above-ground structural elements, etc.) are exposed to water in the form of rain. Treatment of concrete products by immersion and immersion treatment with vacuuming can be carried out in harsh cases of constant water exposure (underground utilities, tunnels, manholes). Conclusions. The limitation of water penetration, and in some cases the absence of water in the pores of building materials impregnated with calcium polysulfide, indicate the preservation of substance, since water is a carrier of substances that destroy concrete and aerated concrete. Accordingly, there is no destructive effect from freezing of water in the pores of such materials as a result of the formation of a nano-sized coating of sulfur particles. Comparison of the results for aerated concrete shows that it acquires superhydrophobic properties, which indicates its excellent modification and expands the possibilities of its use. The data observed for concrete products indicate that after treatment with a calcium polysulfide-based solution, they can be used under conditions of long-term and constant exposure to water

In a number of works by domestic and foreign authors, modern methods are proposed to solve the problem of the effectiveness of decision-making and execution. Quite satisfactory results have been achieved both in theoretical, methodological and applied terms. However, this only casually mentions the effect that occurs in any, and not only an unrealized solution — the appearance of some remnants; not unrealization, but fundamental unrealizability without a remainder. The very nature of unrealizability or the presence of residual has not been considered before, although the effect of residual is constantly observed. The discrepancy between the solution and its implementation was associated with the insufficient quality of the solution or with the shortcomings of its implementation, which is considered in the context of “incomplete information” and “the presence of hidden variables/factors”. This understanding allowed the remnants themselves to be considered in several angles and aspects: a) as a residue from the implementation (“unrealized opportunities”), b) as an over-realization of realized opportunities, c) as errors in the development of solutions, d) as technical, organizational, etc. disadvantages in the implementation of the solution, etc. However, the immediate consideration of the problem of evaluating the effectiveness of decision-making indicates the presence of a fundamental unrealizability in it, which is expressed in the appearance of a remainder when it is implemented in any case. Moreover, this remainder is not associated with realizability as such and not with the solution as such, but with the presence of a special property of residuality, which is of a fundamental nature. The purpose is to identify, describe and propose a method for assessing the phenomenon associated with the incompleteness of the implementation of a management decision, regardless of its quality. A set of logical and descriptive methods was used in the study. Results: a review of situations with the appearance of residues in decisionmaking is carried out; a criterion and a method for evaluating the effectiveness of decisionmaking is proposed, a rule for the residual implementation of a decision is formulated; a justification of the proposed rule in various aspects is given; a classification of options for the unrealizability of decisions is proposed. The results obtained can be useful in making and implementing a decision.

SCIENTIFIC RELEVANCE. The high prevalence of fungal skin infections motivates expanding the range of sertaconazole products for external use.AIM. The study was a preclinical comparison of the safety, antifungal activity, and pharmacokinetics of Sertaverin® 2% medicated shampoo (VERTEX JSC, Russia) with those of Sertamicol® 2% solution for external use (Glenmark Pharmaceuticals Ltd, India) and Nizoral® 2% shampoo (Janssen Pharmaceuticals N.V., Belgium) approved in the Russian Federation.MATERIALS AND METHODS. In the toxicity study, the medicinal products were applied to the skin of male and female outbred rats at doses of 0.5 or 1.5 mL/animal for 28 days. The authors evaluated the pharmacokinetics of two sertaconazole formulations (shampoo and solution) following a single administration to adult male rats at the same dose. Nizoral® was not used in the pharmacokinetics study because it contains a different active substance, ketoconazole. The minimum inhibitory concentration (MIC) was determined using the serial microdilution method in a wide range of concentrations.RESULTS. The medicinal products did not exhibit any significant toxic effects in laboratory animals after 28 days of repeated dermal application. Plasma sertaconazole concentrations were negligible. Sertaconazole was intensively distributed in the liver, which is a highly vascularised organ, and in the target organ (skin at the site of application). The relative bioavailability of sertaconazole from the shampoo relative to that from the solution for external use was approximately 30% in liver tissues and approximately 363% in skin tissues at the application site. Sertaverin® was comparable to sertaconazole in the active substance form in terms of inhibiting the growth of Malassezia furfur strains. The MICs calculated on the active substance basis were ≤16–64 μg/mL.CONCLUSIONS. With its synergistic dual mechanism of action, broad-spectrum antifungal activity, lipophilic properties, and low systemic absorption, Sertaverin® may provide a more effective and safe alternative to marketed medicinal products for scalp diseases.

This study aims to highlight and evaluate the issues at an in-depth level to provide different solutions that are expected to be a reflection for the government, especially the Ministry of Education and Culture, to be able to improve the implementation and monitoring of the Kampus Mengajar Program. A descriptive qualitative approach was used, and the data were collected from a focus group discussion with students of the English Education Study Program at Universitas Lancang Kuning, then the data was analyzed descriptively. The results highlight some problems in the implementation of the Kampus Merdeka Program. These included a lack of coordination and clear communication between stakeholders, which led to confusion among students and schools, uneven targeting of schools, inadequate support for the program, and credit conversion, resulting in frustration and challenges. Addressing these issues, the study recommended increased socialization of the program, transparency in credit equivalency, and more accurate school data collection. In conclusion, this research offers several solutions that are expected to reflect the Ministry of Education, Culture, Research and Technology (Kemendikbudristek) that the Kampus Mengajar Program faces various challenges in its implementation, which need to be addressed for the program to effectively meet its goal of improving education in the 3T areas.

Nowadays, researchers are very interested in studying various Diophantine equations due to their importance in Cryptography, Chemistry, Knot Theory, Astronomy, Geometry, Trigonometry, Biology, Algebra, Electrical Engineering, Economics, and Astrology.

This paper discusses finding solutions to the modified Fractional Black–Scholes equation. As is well known, the options theory is beneficial in the stock market. Using call-and-pull options, investors can theoretically decide when to sell, hold, or buy shares for maximum profits. However, the process of forming the Black–Scholes model uses a normal distribution, where, in reality, the call option formula obtained is less realistic in the stock market. Therefore, it is necessary to modify the model to make the option values obtained more realistic. In this paper, the method used to determine the solution to the modified Fractional Black–Scholes equation is a combination of the finite difference method and the fractional differential transformation method. The results show that the combined method of finite difference and fractional differential transformation is a very good approximation for the solution of the Fractional Black–Scholes equation.

The paper focuses on the Lotka-Volterra function in its discrete form. The purpose of the study was to determine the fixed points of the function. The study employs the Banach Fixed Point Theorem and Contraction Mapping in Metric Space on the function to demonstrate the uniqueness of the fixed points and its continuous stability after several iterations, using the fixed points as the initial conditions. The study has shown that (0, 0), (0, α−1/β), (1+γ /δ, 0 ) and (1+γ/ δ, α−1/ β)are the fixed points of the function, with the initial pair serving as a trivial one and the other three solely depending on the parameter values for the behavior of the function. The outcome of the limit points of the function as the fixed points after several iterations forms a fixed orbit structure of the function, irrespective of the value of the parameter. The study also showed the uniqueness of the fixed points, demonstrating the stability and continuity of the function in its steady state. [ABSTRACT FROM AUTHOR]

We investigate the solutions of the Sylvester-type matrix polynomial equation A(λ)X(λ) + Y (λ)B(λ) = C(λ), where A(λ), B(λ), and C(λ) are the polynomial matrices with elements in a ring of polynomials F[λ], F is a field, X(λ) and Y (λ) are unknown polynomial matrices. Solving such a matrix equation is reduced to the solving a system of linear equations... over a field F. In this case, the Kronecker product of matrices is applied. In terms of the ranks of matrices over a field F, which are constructed by the coefficients of the Sylvestertype matrix polynomial equation, the necessary and sufficient conditions for the existence of solutions X0(λ) and Y0(λ) of given degrees to the Sylvester-type matrix polynomial equation are established. The solutions of this matrix polynomial equation are constructed from the solutions of the linear equations system. As a consequence of the obtained results, we give the necessary and sufficient conditions for the existence of the scalar solutions X0 and Y0, whose entries are elements in a field F, to the Sylvester-type matrix polynomial equation.

A basic theory on the existence and uniqueness of solutions and local solutions for initial value problems (IVPs) of first order ordinary differential equations is established, where the nonlinearities are L p -Carathéodory functions. The basic theory contains three parts: (i) the existence and uniqueness of solutions in C ([ a , b ] , [ c , d ]) ; (i i) the existence and uniqueness of local solutions in C ([ a , a + h 1 (p) ] ; [ c , d ]) , where the expression of the number h 1 (p) will be given and is a computable constant, and (i i i) the existence and uniqueness of solutions and nonnegative solutions by establishing a new Bihari inequality. The classical results dealt with the above part (i i) when f is continuous or an L 1 -Carathéodory function, and only obtained the existence of a number h such that the IVPs had local solutions in C [ a , a + h ]. Our methodology is to use the results obtained on (i) to study the results mentioned in (i i) when p ∈ [ 1 , p ] while the classical results used the Schauder fixed point theorems directly to obtain the existence and uniqueness of local solutions when f is continuous or p = 1. Our results in parts (i) and (i i i) are new. The results in part (i i) are new when p ∈ (1 , ∞ ] and improve the classical results when p = 1. Our results will enrich the classical basic theory. As applications of the basic theory, the existence of solutions and nonnegative local solutions for logistic type population models with heterogeneous environments is studied, where the local rates of changes in the population density are L p -Carathéodory functions.

Due to several geopolitical factors, the number of older migrants increased worldwide with an estimated of 34.3 million in 2020. Older migrants are particularly vulnerable to mental health problems because of their physical health, reduced social networks, and lack of social support. This review aims to summarize current evidence on mental health issues of older persons related to migration and propose possible actions to promote mental health and prevent psychiatric illnesses of this vulnerable group. There are two types of migration in the elderly, for those with and without secured support. Not surprisingly, they have major differences in many characteristics. Common mental health problems in older migrants are depression, loneliness, anxiety, and other symptoms that become complicated with existing or new physical conditions. The links between migration, mental health, and older adults are explored in this paper. Suggested solutions for mental health practitioners and policymakers are proposed. In order to explore these challenges, further suggestions are offered to ensure that older adults’ mental health and wellbeing are looked after.

Accurate size measurements of nanosized polymer chains in dilute solutions is important for understanding polymer behavior, however, these measurements can be challenging to implement accurately, and are technique dependent. Here we explore the use of Fluorescence Correlation Spectroscopy (FCS) to determine the size of single polymer chains in dilute solutions (

At the outset of design projects, our approach typically involves receiving a brief that often presumes a solution. However, in people-centered innovation, our focus shifts from the object or product to the real-life situations and habits of individuals. This paradigm shift entails prioritizing the diverse experiences and contexts of our target audience. Our project teams embrace this perspective by delving into the actual experiences of users with the product. By understanding their desires, needs, and sensory encounters, we aim to offer solutions that resonate with their lived realities. This approach necessitates a deep dive into users' activities, aspirations, and genuine requirements. The paper's objective is to meticulously gather and address these needs, crafting design solutions that truly align with users' preferences and aspirations.

The healthcare system in Pakistan faces several challenges, namely due to incompetence and a lack of provider responsiveness to the needs of consumers. Two parallel systems exist in the healthcare system of Pakistan. One consists of public hospitals that remained short, even, of basic healthcare facilities, and the other consists of private hospitals that are too costly for the people of Pakistan to afford. Solutions to the stumbling and compromised healthcare system of Pakistan are adequate financial support and infrastructure development. A dire need to invest in the healthcare system is required; otherwise, the healthcare system in Pakistan will continue fighting for its survival rather than improving and competing with the healthcare systems of other nations in the region. The overall data quoted here demonstrates that up-scaling of initiatives in the country would require lot of cautions to be taken by the government.

Introduction and Objective: Ethical practice is a vital aspect of nursing interventions. Complying with the ethical aspects of the intervention procedure in a stressful nursing environment is not easy and nurse managers always face ethical challenges which are in conflict with their personal values and norms. Identifying and solving these challenges improves the efficiency and effectiveness of nursing care activities. Therefore, this research was done to explain the ethical challenges of nurse managers and practical solutions from their perspective. Material and Method: It is a qualitative study that was carried out based on the phenomenological method in 2022. The participants of this study were 20 nurse managers of Arak hospitals who were selected by purposive sampling until data saturation. The data were collected through semi-structured interviews for 30 to 90 minutes. Data collection was carried out with the participant's consent, using a digital recording device and verbatim transcription, and then it was analyzed using Van Manen's six-step hermeneutic phenomenological approach. Findings: The results of this study could provide a clear picture of ethical challenges and their practical solutions from the nurse managers' perspective in the form of four themes of managerial ethical challenges which include challenges facing physicians, organizations, employees, managers, and three themes for practical solutions, including organizational solutions, interpersonal solutions, and educational solutions which were manifested. Conclusion: Nurse managers are always faced with ethical challenges in their daily activities. To deal with these challenges, they must be familiar with the rules and principles of professional ethics, practical standards, and laws related to patients' rights. Ethical principles and awareness of the ethical decision-making process are useful and effective in having capable and ethical nurses who provide competent care. To deal with ethical challenges, it is suggested to consider self-care strategies and structural and specialized support in each center, which will ultimately lead to the improvement of service quality and the promotion of ethics in care-treatment environments.

The "waiver of criminal prosecution" institution was introduced into Romanian criminal procedural legislation by Law no. 135/2010 on the Code of Criminal Procedure. It appears as an exception to the principle of the legality of the criminal process - regulated by the Romanian legislator in favor of the principle of expediency. The legislator opted for the introduction of this institution in the legislation, considering the costs involved in the activity of criminal investigation and trial in the case of certain crimes. The appearance of this institution "justifies", to some extent, the non-taking over by the legislator in the new provisions of the content provided by art. 181 of the former Criminal Code (1969). The provisions included in the content of art. 181 of the previous Criminal Code (1969) allowed the judicial bodies to find that some acts provided for by the criminal law did not present the social danger of a crime, which allowed the application to the perpetrator of an administrative measure provided for in Article 91 of the previous Criminal Code (1969).

The computational study of fixed-point problems in distance spaces is an active and important research area. The purpose of this paper is to construct a new iterative scheme in the setting of Banach space for approximating solutions of fixed-point problems. We first prove the strong convergence of the scheme for a general class of contractions under some appropriate assumptions on the domain and a parameter involved in our scheme. We then study the qualitative aspects of our scheme, such as the stability and order of convergence for the scheme. Some nonlinear problems are then considered and solved numerically by our new iterative scheme. The numerical simulations and graphical visualizations prove the high accuracy and stability of the new fixed-point scheme. Eventually, we solve a 2D nonlinear Volterra Integral Equation (VIE) via the application of our main outcome. Our results improve many related results in fixed-point iteration theory.

The particle swarm optimization (PSO) algorithm is widely used for optimization purposes across various domains, such as in precision agriculture, vehicular ad hoc networks, path planning, and for the assessment of mathematical test functions towards benchmarking different optimization algorithms. However, because of the inherent limitations in the velocity update mechanism of the algorithm, PSO often converges to suboptimal solutions. Thus, this paper aims to enhance the convergence rate and accuracy of the PSO algorithm by introducing a modified variant, which is based on a hybrid of the PSO and the smell agent optimization (SAO), termed the PSO-SAO algorithm. Our specific objective involves the incorporation of the trailing mode of the SAO algorithm into the PSO framework, with the goal of effectively regulating the velocity updates of the original PSO, thus improving its overall performance. By using the trailing mode, agents are continuously introduced to track molecules with higher concentrations, thus guiding the PSO's particles towards optimal fitness locations. We evaluated the performance of the PSO-SAO, PSO, and SAO algorithms using a set of 37 benchmark functions categorized into unimodal and non-separable (UN), multimodal and non-separable (MS), and unimodal and separable (US) classes. The PSO-SAO achieved better convergence towards global solutions, performing better than the original PSO in 76% of the assessed functions. Specifically, it achieved a faster convergence rate and achieved a maximum fitness value of −2.02180678324 when tested on the Adjiman test function at a hopping frequency of 9. Consequently, these results underscore the potential of PSO-SAO for solving engineering problems effectively, such as in vehicle routing, network design, and energy system optimization. These findings serve as an initial stride towards the formulation of a robust hyperparameter tuning strategy applicable to supervised machine learning and deep learning models, particularly in the domains of natural language processing and path-loss modeling.

This work focuses on MAR-M247 Ni-based superalloy manufactured via directional solidification at various withdrawal rates (3.4 or 5.0 mm/min) and shell mold temperatures (1510 °C or 1566 °C) after solution heat-treatment (SHT). Observations and analyses of four casting variants were carried out using thermodynamic simulations, differential scanning calorimetry (DSC), X-ray diffraction (XRD), light microscopy (LM), scanning electron microscopy (SEM), X-ray spectroscopy (EDX), and tensile tests at ambient temperature. The solidus and liquidus temperatures were very similar for all variants and were in the range of 1263–1264 °C and 1356–1359 °C, respectively. The presence of the γ, γ′, MC carbides, and M5B3 phases was confirmed. Microstructure differences were observed depending on the manufacturing parameters. The castings' dendritic regions consisted of γ′ precipitates surrounded by the matrix, with a mean size ranging from 0.203 to 0.250 μm, depending on the casting parameters. The amount of the MC carbides in the interdendritic spaces was in the range of 1.87–1.92%. The tensile tests determined that castings produced with preheat temperature of 1566 °C were characterized by higher elongation and slightly lower yield strength in comparison to 1510 °C.

Demographic growth in Colombian municipalities has notably influenced the quality of housing. This article aims to propose a method to characterize the residential building stock of the municipalities located in the cold and temperate climate, structured in three levels of characterization that yield different results: (i) temporary characterization, (ii) housing characterization, and (iii) characterization of the constructive assemblies. In level i, five time periods marked by historical, social, and normative events are obtained. As a result of levels, i and ii, the building taxonomy is drawn, that can be determined based on several criteria: urban location (neighbourhood or urbanization), residential typology (single-family or multi-family), adjacency (isolated, corner or between party walls), and number of floors (1, 2/3, more than 3). In level iii, constructive assemblies are analyzed, and a catalogue of typical assemblies is drawn up for each of the time periods and typologies. The results of the study serve as a tool for government entities to suggest the level of socioeconomic stratification of the dwellings based on the typology and construction quality.

In this article, the question of how the concept of the soul can be grasped in postmodernity is explored. In doing so, proposed definitions of analytical psychology will be presented and placed in the contemporary historical context of postmodernism. Since the concept of soul is no longer en vogue in today’s world, a disenchantment of the world is increasingly taking place, which is paid with a great inner-psychic price, which can also be seen in the social reaction to the Corona pandemic, the climate crisis and wars. Proposed solutions are shown as to how, with the help of the use of concepts of analytical psychology, these crises can be faced, and at the same time the soul can be given a place again in postmodern society.

This article discusses the aspect of conflict resolution depicted in the text of Hikayat Merong Mahawangsa. Conflict is a form of social interaction that involves opposing views between two or more parties. When disagreements arise, it is essential to resolve conflicts using specific methods to prevent them from becoming detrimental to society. Conflict resolution is the process of addressing or overcoming issues that occur within a community. Research related to conflict resolution within the text of Hikayat Merong Mahawangsa has not been extensively explored, especially from the perspective of Ralf Dahrendorf. The aim of this study is to analyze the conflict resolution depicted in the text of Hikayat Merong Mahawangsa. The research is focused on the historical literary text of Hikayat Merong Mahawangsa as studied by Siti Hawa Haji Salleh (1988). Additionally, this article adopts a qualitative approach utilizing literature review and textual analysis methods. Therefore, the primary framework applied in this study is Ralf Dahrendorf's conflict resolution theory. According to Dahrendorf's conflict theory (1959), only two conflict resolution methods are employed, namely consiliation and mediation, in accordance with the types of conflicts depicted in the text of Hikayat Merong Mahawangsa. The research findings reveal that conciliation was applied to resolve personal and racial conflicts, while mediation was employed to address power struggles and conflicts between social classes. The study indicates that Hikayat Merong Mahawangsa provides evidence of the wisdom of traditional Malay society in effectively managing conflicts and crises. [ABSTRACT FROM AUTHOR]

Climate change is a constant threat to global food security. In Sub‐Saharan Africa (SSA), extended dry spells, heavy rainfall, flooding, and tropical storms have driven a large percentage of the population to a severe food crisis. Climate‐smart agriculture (CSA) is a potential comprehensive solution whose adoption can mitigate climate change and its ramifications on the state of food security in the region. CSA combines innovation, the use of technology, extensive research, stakeholder involvement, and data to increase food production, optimize resource allocation and utilization, and enhance the region's ability to feed its population. The adoption of CSA has succeeded in increasing agricultural productivity in several parts of SSA and will help towards the building of resilience food systems across the region amid constant and unpredictable climate change and its far‐reaching impacts in the region. For the sustained and universal adoption of CSA within the region, there is a need for more stakeholder involvement in its development and adaptation to the needs of specific communities. Furthermore, it is necessary to leverage the positive impact of the approach by expanding its scope beyond climate change mitigation to prevention and control, and ultimately help in achieving the United Nations SDG 2 and 13.

Introduction: It is assumed that the level of cognitive flexibility and maladaptive problem-solving methods, probably lead to the exacerbation of preclinical obsessive-compulsive symptoms. Therefore, an attempt has been made to show how the level of cognitive flexibility and the type of problem-solving methods can predict the severity of premorbid symptoms of obsessive-compulsive disorder. Method: This study followed a descriptive cross-sectional design. Sampling was done using cluster sampling among university students. The number of samples was 263 people. In addition, the data analysis method was regression. Results: It was shown that problem-solving methods based on thinking and feeling significantly predict obsessive-compulsive slowness. It was also observed that feeling-focused problem-solving can significantly predict obsessive-compulsive hesitation. Conclusion: It seems that encouraging people to use a specific model of problem solving, such as just thinking, can lead to a decrease in individual functions, especially executive functions. Moreover, finding the optimal level of cognitive flexibility based on reality can increase the efficiency and satisfaction of a person. [ABSTRACT FROM AUTHOR]

Temozolomide (TMZ) is part of the therapeutic armamentarium used in managing pediatric cancers; however, available oral forms (capsules) are not adapted for use in children. Our aim was to assess the dose accuracy and stability of TMZ using capsule contents mixed with food compared with a novel, ready-to-use liquid formulation specifically developed for children (Ped-TMZ, brand name KIZFIZO). Dose accuracy and TMZ stability testing were performed with TMZ capsule contents (90 mg) mixed with food vehicles (apple juice, apple sauce, cream, milk, and mashed potatoes) and compared to an equivalent dose of Ped-TMZ. Acceptance criteria were predefined for TMZ (95.0–105.0%) and its degradation product amino-imidazole-carboxamide (AIC; <1%) content. The delivered dose was significantly higher using Ped-TMZ (96.6 ± 1.2%) and within the predefined criteria for TMZ content, whereas it was systematically under the lower specifications of 95% using capsule-derived preparations with apple juice (91.0 ± 1.5%) and apple sauce (91.6 ± 1.4%), respectively (p < 0.0001). In chemical stability tests, the four food vehicles (apple sauce, cream, milk, mashed potatoes) had a significant effect on TMZ stability (p = 0.0042), and the AIC significantly increased with time in three of the four vehicles (p < 0.0001). Only 1/72 of preparations from capsules met the predefined acceptance criteria, whereas Ped-TMZ showed no TMZ loss, and the AIC remained within specifications. In conclusion, mixing TMZ capsule content with food may result in significant underexposure, possibly even greater in routine practice, as complete food intake by the child is unlikely.

Siliconization of the tokamak walls is a candidate method to improve plasma confinement in fusion tokamaks containing tungsten plasma facing components (W PFCs). To understand the interactions of silicon (Si) with W, the Si behavior in bulk W, and near three low-index W surfaces ((100), (110) and (111)) has been investigated using first-principles density functional theory. In bulk W, Si interstitial atoms have a low solution ability and high mobility, and Si atoms can be strongly trapped by W vacancies. The interaction between two Si adatoms is responsible for the stability of adatom superstructures on W surfaces, consistent with previous experimental observation (Tsong and Casanova 1981 Phys. Rev. Lett. 47 113). Although the coverage dependence of Si adsorption and diffusion energetics on surfaces is related to surface orientation, the W(110) surface has lower Si adsorption affinity and higher Si diffusivity than either the W(111) or W(100) surfaces. The most stable Si adatom superstructure on W surfaces is: square c(2 × 2) pattern on W(100) covered with 0.5 ML Si; rectangular c(4 × 2) pattern on W(110) with 0.25 ML Si; and rhombus p(1 × 1) pattern on W(111) with 1 ML Si. The coverage dependence of Si mobility on/toward W surfaces is generally related to the stability of the Si superstructures as a function of coverage on each surface. Interestingly, Si adatoms prefer to transport below the surface and into W subsurface by an exchange mechanism with W atoms, indicating the likelihood of epitaxial growth of W silicide layers on W surfaces during the operation of W PFCs.

We suggest a novel iterative scheme for solutions of singular boundary value problems (SBVPs) that is obtained by embedding Green's function into the Picard-Mann Hybrid (PMH) iterative scheme. This new scheme we call PMH-Green's iterative scheme and prove its convergence towards a sought solution of certain SBVPs. We impose possible mild conditions on the operator or on the parameters involved in our scheme to obtain our main outcome. After this, we prove that this new iterative scheme is weak w2-stable. Eventually, using two different numerical examples of SBVPs, we show that our new approach suggests highly accurate numerical solutions as compared the corresponding Picard-Green's and Mann-Green's iterative schemes.

Alternative sources of protein are gaining popularity since they require less natural resource input, but still provide a significant amount of protein as compared to traditional protein sources. Insect protein is one of the alternative protein types, and due to its nutritional benefits, research interest in Bombay locust (Patanga succincta) (BL) protein has grown. In the present work, we aimed to determine the protein content, yield, molecular weight profile, and functional properties such as protein solubility, emulsion, and foam properties of BL protein extracted using distilled water, salt (NaCl), or alkaline (NaOH) solution, at the concentrations of 0.5, 1.0, or 1.5%. The highest protein extraction yield was alkaline soluble protein (22 - 28%), which was followed by water (16%) and salt (11 - 13%) soluble proteins. The protein powder prepared by 0.5% alkaline extraction had the highest foam capacity (33.33%) and foam stability (12.50%) (p < 0.05), but the water soluble protein powder had the highest emulsion activity index (118.3 m²/g) and emulsion stability index (52.45 min) (p < 0.05). These results indicated that the type and concentration of solution could have an impact on the protein extraction yield, molecular weight profile, and functional characteristics.

In this article, the problem for a differential-algebraic equation with a significant loads is studied. Unlike previously studied problems for differential equations with a significant loads, in the considered equation, there is a matrix in the left part with a derivative that is not invertible. Therefore, the system of equations includes both differential and algebraic equations. To solve the problem, we propose a modification of the Dzhumabaev’s parametrization method. The considered problem is reduced to a parametric problem for the differential-algebraic equation with significant loads. We apply the Weierstrass canonical form to this problem. We obtain parametric initial value problem for a differential equations and an algebraic equations with a significant loads. The solvability conditions for the considered problem are established.

The apparent molar volume(Vϕ) and apparent molar isentropic compressibility (Kϕ,s) of ethylene glycol (EG), diethylene glycol (DEG) and triethylene glycol (TEG) in trisodium ethylenediaminetetraacetic acid solution (aqueous) have been estimated based on measured experiments values for both the density (ρ) and sound speed (s) at (288.15, 298.15, 308.15 and 318.15) K and 0.01 MPa as well. From the foundation in infinite dilution limiting apparent molar volumes (Vϕ∘) and isentropic compressibility(Kϕ,s∘) its transfer properties (ΔVϕ∘, ΔKϕ,s∘), expansibility coefficients(∂Eϕ∘/∂T)P, expansion coefficient (α) and interactions coefficients (VAB,KAB,VABB,KABB) the various interactions among glycols and EDTA in aqueous solution were investigated and addressed. Fourier transform infrared spectroscopy study had also been carried in binary solution.

Although in recent years we have seen an increasing number of dentists in the country, unfortunately, the quality of education of students has not changed much during these years. The final goal of the dental education system is to prepare and create the necessary skills in students to provide the most appropriate and excellent dental treatment to society. One of the major problems is the inconsistency of the capacity of accepting students with the capacities of universities (facilities, equipment, professors, educational space, and the number of patients). Being apart from the size of the treatment departments and the presentation of the treatment plan by the university professors without defining any role for the students is one of the main reasons that cause the students to lack a comprehensive view and the ability to make decisions regarding the treatment of patients. The excessive separation of the departments takes away the opportunity for comprehensive education from the students so that they are not familiar with inter-departmental consultations, which ultimately affects their capabilities. The need to change the attitude of professors and students toward education and guidance towards providing a health-oriented treatment plan can cause many reforms in the educational system. One of the most important solutions is creating motivation and empowering students with new educational methods and involving students in the entire patient treatment process. It is easy to increase the educational quality of universities by considering simple solutions even despite many structural problems and at the same time provide better quality medical services to the people. The more attention we pay to educating students and solving the problems of the dental education system, in the not-too-distant future we will have a society with higher oral health and better quality dental services.
