A Benchmark Study on Steepest Descent and Conjugate Gradient Methods-Line Search Conditions Combinations in Unconstrained Optimization
Authors: Kiran Kadir
Published: July 2022

In this paper, it is aimed to computationally conduct a performance benchmarking for the steepest descent and the three well-known conjugate gradient methods (i.e., Fletcher-Reeves, Polak-Ribiere and Hestenes-Stiefel) along with six different step length calculation techniques/conditions, namely Backtracking, Armijo-Backtracking, Goldstein, weakWolfe, strongWolfe, Exact local minimizer in the unconstrained optimization. To this end, a series of computational experiments on a test function set is completed using the combinations of those optimization methods and line search conditions. During these experiments, the number of function evaluations for every iteration are monitored and recorded for all the optimization method-line search condition combinations. The total number of function evaluations are then set a performance measure when the combination in question converges to the functions minimums within the given convergence tolerance. Through those data, the performance and data profiles are created for all the optimization method-line search condition combinations with the purpose of a reliable and an efficient benchmarking. It has been determined that, for this test function set, the steepest descent-Goldstein combination is the fastest one whereas the steepest descent-exact local minimizer is the most robust one with a high convergence accuracy. By making a trade-off between convergence speed and robustness, it has been identified that the steepest descent-weak Wolfe combination is the optimal choice for this test function set.
A new fitness-based selection operator for genetic algorithms to maintain the equilibrium of selection pressure and population
Authors: Batool Naqvi Fakhra , Yousaf Shad Muhammad
Published: July 2022

A genetic algorithm is one of the best optimization techniques for solving complex nature optimization problems. Different selection schemes have been proposed in the literature to address the major weaknesses of GA i.e., premature convergence and low computational efficiency. This article proposed a new selection operator that provides a better trade-off between selection pressure and population diversity while considering the relative importance of each individual. The average accuracy of the proposed operator has been measured by χ2 goodness of fit test. It has been performed on two different populations to show its consistency. Also, its performance has been evaluated on fourteen benchmark problems while comparing it with competing selection operators. Results show the effective performance in terms of two statistics i.e., less average and standard deviation values. Further, the performance indexes and the GA convergence show that the proposed operator takes better care of selection pressure and population diversity.

Published: July 2022

The surface hardening of steel components makes it possible to achieve high abrasive wear resistance without the necessity of hardening the entire cross-section of a given element. As a result, lower stress are introduced and the cost of the process can be reduced. Because of very high heating rates (of up to 10⁹ K/s) as well as the ease of dynamic deflection and focusing, the use of the electron beam to harden component surfaces enables the obtainment of surface layers characterised by required properties. This article constitutes an overview of publications concerning electron beam-based surface hardening.

Authors: Kudryavtseva E. V. , Kurbatova N. V. , Кovalev V. V. , Islamidi D. K.
Published: July 2022

Introduction. Normal ovarian reserve (OR) determining the ovarian response to follicle development containing fully-featured oocytes is an important factor in pregnancy, including assisted reproductive technology (ART) programs. The causes of premature OR decrease are multifactorial. The study of gene polymorphism as a cause of the premature OR decrease deserves attention.

Aim: to determine genetic predisposition to premature OR decrease and create a prognostic model based on study results.

Materials and Methods. A retrospective comparative cohort study was conducted. A total of 200 reproductively active patients with infertility underwent ART were examined. The patients were divided into 2 groups: Group 1 included 100 patients with a premature OR decrease; Group 2 consisted of 100 patients with a normal OR. All patients underwent molecular genetic study. Genetic polymorphisms of the genes ESR1, ESR2, FSHR, CYP19A were studied.

Results. The final clinical phenotype is shaped by multiple factors – genetic and environmental. Several genetic variants contribute to the formation of premature decrease in ovarian reserve. Gene combination of CYP19A1 and FSHR displayed the greatest synergistic effect, potentiating each other and predisposing to a poor ovarian response as part of stimulated superovulation.

Conclusion. Identifying genetic markers is a promising method for individual OR evaluation, including its premature decline. Multilocus analysis and a prognostic model based on combining several polymorphic gene variants will allow to assess risks of premature OR decrease and individualize ART programs.

Preeclampsia (PE) is a multisystemic disease that has been recorded as a complication in up to 15 % of pregnancies being lead cause of maternal mortality worldwide. Despite that PE pathophysiology has not been fully elucidated, it is currently believed that the endothelial dysfunction and pro-inflammatory status play a key role in its development, which account for impaired implantation processes as well as trophoblast invasion during placentation. Altogether, it results in developing generally accepted clinical symptoms “triad”: arterial hypertension, proteinuria, and edema. PE is also characterized by clotting disorders that cause an increased risk of maternal venous thromboembolism. It should be remembered that the related risk may be markedly elevated in the postpartum period. The mechanisms underlying the development of thrombosis high risk remain to be fully investigated, albeit upregulated expression of procoagulant factors, endothelial dysfunction, compromised endogenous anticoagulant activity, and increased platelet activity result in prothrombotic predisposition.

El pasado en el presente: la obra de Edgar Negret y Eduardo Ramírez-Villamizar
Authors: Castellanos Luisa
Published: July 2022

Durante el siglo XX, la historia del arte colombiano y latinoamericano se encargó de revisar la obra de los artistas Edgar Negret y Eduardo Ramírez-Villamizar desde la abstracción y los importantes cambios que su lenguaje geométrico generó en la escena artística colombiana. Pero a pesar de ser un tema recurrente en sus obras, sus títulos y sus discursos, el interés de estos artistas por el arte precolombino ha sido tratado de manera marginal. Este trabajo busca, entonces, analizar la manera en que Negret y Ramírez-Villamizar se enfrentaron a los artefactos precolombinos y cómo se evidencia este legado en su obra. De esta manera, se comprueba que, a través de la geometría y los materiales, los artistas colombianos buscan reconectar el pasado precolombino con el presente moderno, construyendo un puente que permita a lo precolombino ser incorporado en el arte moderno y considerado como una fuente por artistas venideros.
Las tres dicotomías en la Lamentación sobre Cristo muerto
Authors: Leon massa Valeria
Published: July 2022

Lamentación sobre Cristo muerto (1306) es uno de los 37 frescos que se encuentran dentro de la Capilla de Arena, una sencilla iglesia que esconde dentro de sus pequeños confines y simples terminados un ciclo de trascendentales pinturas acerca de la vida de Jesús y de la Virgen María. La pintura fue terminada en el año 1306 por el pintor florentino prerrenacentista, Giotto di Bondone. El valor y discusión actual de la imagen reside en su clara representación de lo que fue el arte prerrenacentista para el desarrollo de la esfera artística occidental. Además, la importancia del objeto recae en su viva manifestación de lo que fue el ingenio de Giotto y su ruptura artística dentro del medio. Sobre todo, la obra posee gran relevancia hoy porque muestra la capacidad del arte de mantenerse y mantener a su espectador en una constante fluctuación dentro de distintas dicotomías. Esta última característica de la pintura es la base de este análisis, en el cual se busca entender a fondo tres de las dicotomías que exhibe la imagen, las cuales son de la humanidad y divinidad, la belleza y el dolor, y el antes y el ahora. A través de una detallada observación y un estudio crítico de los principales elementos de la obra, del contexto que la rodea y de tres de las dicotomías que exhibe, se podrá entender, de mejor forma, el estado de constante fluctuación en el que su espectador se ve involucrado.
Con fulgor y sin fronteras: la voz poética de Diamante de Azael Álvarez
Authors: Granizo Lucía
Published: July 2022

El presente texto establece un análisis de la voz poética de género fluido en Diamante (2019) del poeta ecuatoriano Azael Álvarez. En primera instancia, se realiza una investigación de la disputa sobre el género y se exploran las posturas de Hines y Butler sobre su fluidez. Este punto de partida habilita el análisis de la edificación de la voz lírica a partir de la ruptura del género gramatical fijo, la fluidez performativa, el continuo devenir y la marginalización a la que es expuesta por no formar parte del marco binario genérico. El estudio ofrece una interpretación abierta del género y su fluidez desde la experiencia subjetiva de la voz lírica y da cuenta cómo el orden simbólico y el orden de las representaciones operan en su contra para exponerla a una vida precaria.

Published: July 2022

For many researchers, satisfaction is a perennially popular research topic, with satisfaction in education being one of the most prevalent aspects. There are a few previous studies that have looked into the satisfaction of parents and students with their high school and college experiences. However, research on parental satisfaction with preschool education is limited, particularly in Vietnam. The purpose of this study was to determine the factors that influenced parents' satisfaction with their children's preschool education. A total of 511 parents in Danang agreed to take part in the study. In this study, multi-regression analysis was carried out to find out relations between response to information, teachers, and educational programs; financial costs; facilities, equipment, and supplies; care and support; and parents' satisfaction. It was found that a majority of participants expressed satisfaction with the quality of preschool education and showed their willingness to pay for it. The most influential factor affecting parents' satisfaction was identified as facilities, including other factors such as response to information, teachers, and educational programs; financial costs; care and support discussed in detail. Future research may build on the findings of this study and investigate additional factors such as practical and convenience factors or a measure of average classroom learning gains that may have an impact on the satisfaction of parents.
Case of Liquidity Risk: Demirbank
Authors: YAZICI Mehmet
Published: July 2022

Liquidity risk is the possible loss of funds as a result of not being able to find the required amount of funds at an appropriate cost when needed or not being able to sell a financial asset at the required time and price. Briefly, it is the risk of maturity mismatch of cash inflows and outflows. Banks that use the short-term funds they collect in long-term assets are exposed to such a risk. Despite international regulations, it is observed that even in banks with sufficient capital levels, problems arise in the management and liquidity due to the change in risk appetites of different financial institutions in different periods. After the World War II, and especially with the effect of the liberalization policies of the Democratic Party in Türkiye, which was in ruling between 1950-1960, 24 new banks were established. In the case of Demirbank, which resulted to took over by the Savings Deposit Insurance Fund (SDIF) in 2000, especially all the process until the transfer of the bank to the fund, is a lesson to learn on liquidity risk management. In this article it is aimed to shed light on a period in Turkish banking history, the theoretical framework and the regulatory and supervisory processes and the reactions of related institutions.
Resisting the Oppressive Paternal Metaphor of God in Michèle Roberts’s "Impossible Saints"
Authors: Dobrogoszcz Tomasz
Published: July 2022

The protagonist of Michèle Roberts’s Impossible Saints, Josephine, establishes a nonconformist convent for women who seek communion with God by following an unorthodox path of sensual spirituality. Impossible Saints intersperses Josephine’s story with a number of miniature narratives depicting fictional lives of saints, rewritten in a feminist manner, portraying both the female predicament in the patriarchally structured society and women’s struggle for empowerment in which they rebel against masculinist conventions. The article employs feminist thought, derived mainly from Julia Kristeva, to examine the way in which Roberts problematizes the relation of the Catholic Church to the position of women as well its concern with the human body. The bodily dimension of the divine, as proposed by Luce Irigaray, manifesting in the emancipatory communal experience of women in Josephine’s convent, greatly contrasts with the Catholic regulatory character of religiosity. The analysis also situates the patriarchal institution of the Church in the context of the Lacanian order of the symbolic and his notion of the Name-of-the-Father. It culminates in exploring the issue of the metaphor of God as seen through the traditional patriarchal frame which pictures God as masculine.

The low quality of human resources and inadequate facilities in madrasas are new problems for educational institutions based on an integrated curriculum. If these conditions continue to be allowed, then the goals of Islamic education will experience obstacles. This qualitative research was conducted to analyze the integrated curriculum management, as well as the strengths and weaknesses of its implementation at MA Al-Mumtaz Gunungkidul Special Region of Yogyakarta. Based on reliable sources of document data and sources, through observation, documentation, and in-depth interviews, inductive analysis was carried out to find meaningful final findings of research results. The results show that at MA Al-Mumtaz, 3 integrated curricula have been implemented, namely, the National curriculum, the Islamic Boarding School curriculum, and the Entrepreneurship curriculum. Management principles are also implemented, starting from curriculum planning by the Pondok Pesantren component at the beginning of each new school year. The implementation of the curriculum is assigned to the coordinators of the education sub-section with its members to students. The implementation of the curriculum is based on the autonomy of the foundation, an integrated curriculum system, a curriculum modification system, and the primacy of affective assessment. Supervision is carried out at the beginning, middle, and end of the school year. Its strengths are the one-way command system, the creation of independent human resources, and the consistency of regulations at MA Al-Mumtaz. Meanwhile, its weaknesses are found in organizing educators and education personnel, as well as community acceptance.
SDS-PAGE Analyses and Electrophoretic Band Characterization of Three Cultivars of Grass Pea based on Seed Storage Proteins
Authors: Mondal Animesh , De Kalyan Kumar
Published: July 2022

Background: Grass pea (Lathyrus sativus L.) is valued for its high dietary protein content, high degree of adaptability under extreme conditions, disease resistance and low input requirement for its cultivation. This species is represented by several sub-species and important varieties which are not well distinguishable by their morphological characters. The objective of present study was to determine the cultivar differences based on seed storage protein by using SDS-PAGE and to obtain information useful for a breeding program. Methods: Gel electrophoresis was carried out in the discontinuous buffer system in a vertical electrophoresis apparatus and electrophoretic data were documented by using a gel documentation system. Seed protein sub-fractions (albumins, globulins, glutelins and prolamins) from seeds were extracted and quantified. ODAP (β-N-oxalyl-L-a,β-diaminopropionoc acid) an undesirable and toxic non-protein amino acid (responsible for ‘neuro-lathyrism’ disease) content was estimated. Result: The differences among cultivars were observed and clearly identifiable from their protein banding patterns in view of in number of bands, position of the bands and molecular weight of the bands etc. Quantity of total protein and sub-fractions of protein (albumins, globulin, glutelins and prolamins) of seed storage proteins also showed the variation among the three cultivars. ODAP content estimated in three grass pea cultivars was found very low ranging which is highly desirable for cultivation.

Published: July 2022

Background: The emergence of a multidrug resistance phenotype is most likely outcome of co-existing multiple mechanisms. The underlying molecular mechanism of carbapenem resistance is poorly understood in bacterial isolates of animal origin. The present study investigates the resistance mechanism for reduced susceptibility to carbapenem in E. coli. Methods: The study includes 12 multidrug resistant E.coli isolates showing decreased susceptibility to imipenem. Carbapenemase production was evaluated by the mCarba-NP test. The presence of the carbapenem resistance gene was confirmed by multiplex PCR. Efflux pump activity was accessed by broth microdilution method with or without selective efflux pump inhibitor. We analyzed differential expression of the outer membrane porin genes (ompF, ompC) and efflux pump genes (acrA, acrB) by quantitative real-time PCR analysis. Result: We observed increased expression of acrA and acrB genes in all the E. coli isolates under imipenem stress. A positive correlation (p less than 0.001) was evident between imipenem MIC and acrA and acrB over-expression in these isolates. A significant decrease in ompF and ompC expression was observed in these isolates under imipenem stress. The change in MIC was not correlated with the corresponding OmpC and OmpF gene expression. The results suggest the importance of efflux pump and porins proteins in the emergence of multidrug resistance besides carbapenemase production.

Published: July 2022

Background: Sunnhemp is an important bast fibre crop suitable for diversified uses. Recently, its cultivation has started expanding considerably throughout the world particularly for its potential usage in sustainable farming and in reducing use of synthetic fertilizers from agricultural system. Seed production and fibre production are mutually exclusive in sunnhemp because of different photo-period requirements for these purposes and destructive fibre extraction process. The major limitation in sunnhemp popularization cultivation is availability of seed. In this context, present study was undertaken to identify proper sowing time and suitable cultivars, and find correlation of seed yield with weather parameters for Telangana state of India. Methods: Three dates of sowing and six cultivars were tested in split-plot design over two years i.e., 2019-20 and 2020-21. Pooled data over two years were analyzed for important seed yield related traits. Result: The analysis of variance revealed significant influences of sowing dates, cultivars and their interaction on majority of the traits. Among three sowing dates, 2nd week of September was the best suited for seed yield and related traits. The cultivar SUIN 037 recorded maximum seed yield followed by SUIN 053. Among different combinations of treatment, the cultivars SUIN 037 and SH 4 sown during 2nd week of September resulted in maximum and comparable seed yield. The correlation and regression studies showed that the weather parameters had significant influences on yield attributes of sunnhemp.

Published: July 2022

This study purposes to compare student learning activities in fully online learning and blended learning. This study uses the mixed methods approach (explanatory sequential model). 42 junior high school teachers were comprised as the sample. Learning activity questionnaire (LAQ) and interview procedures were used as a data collection tool. The data obtained were analysed using Rasch analysis. Rasch analysis is a statistical technique for defining the measure of human performances, attitudes and insights. The results showed that almost all respondents agreed with all statements on the questionnaire. The percentage of respondents’ approval of statements using blended learning is higher than respondents who use fully online learning. Thus, it can be determined that fully online learning and blended learning can develop student learning activities. The researcher recommends that in the strategic plan for managing learning services, online learning should provide additional computing infrastructure to run the two learning methods.

The relationship between self-regulation learning and online learning adoption
Authors: Almoslamani Yousef
Published: July 2022

As the online learning environment continues to proliferate and dominate higher education learning systems, more investigation is required to explicate the adoption rate of these systems and the factors influencing students’ adoption. Previous research has demonstrated the learning environment role in self-regulation learning and the association between self-regulation learning and the dropout rate (Kim et al., 2017). But yet there is rare research addressing whether self-regulation learning skills are associated with online learning adoption. This study explicates how self-regulation learning skills associate with the online learning adoption level of university students. A sample of 688 students enrolled in Saudi Electronic University answered a self-administrated questionnaire distributed via their students’ emails. The questionnaire consists of two parts: self-regulation skills and online learning adoption. Chi-square analysis reveals statistically significant positive associations between the overall score of self-regulation skills, goal setting, environment structuring, time management, help-seeking, use of self-regulation strategies, self-evolution and online learning adoption. The results accommodate with the literature that a higher level of self-regulation skills fosters openness to experience. The study recommends fostering students’ self-regulation skills to increase their readiness for online learning environments.

1,5-Anhydroglucitol as a Marker of Acute Hyperglycemia in Cardiovascular Events
Authors: Migała Marta , Chałubińska-Fendler Justyna , Zielińska Marzenna
Published: July 2022

1,5-anhydroglucitol (1,5-AG) is a biomarker of acute hyperglycemia in diabetology and also in cardiodiabetology. It is used to monitor fluctuating glucose levels. 1,5-AG is a monosaccharide that is biochemically similar to D-glucose and originates from the nutrition. The presence of
1,5-AG in blood and tissue is nearly constant due to reabsorption in the renal proximal tubule. In acute hyperglycemia, renal reabsorption is inhibited by glucose and 1,5- AG is excreted in the urine, while its serum level decreases rapidly. 1,5-AG reflects glucose excursions over 1-3 days
to 2 weeks. In this regard, low levels of serum 1,5-AG can be a clinical marker of short- term glycemic derangements such as postprandial hyperglycemia, which is an important risk factor for the pathogenesis of coronary artery disease (CAD) as low levels of 1,5-AG reflect severe plaque calcification
in CAD and correlate with high-density lipoprotein cholesterol (HDL-C) levels. For these reasons, 1,5-AG may also be a marker for atherosclerosis; in fact an even better marker than HbA1c or fructosamine which are normally used. 1,5-AG may also be a predictor of cardiovascular disease, left
ventricular dysfunction after acute coronary syndrome (ACS), and mortality after ACS. This articles reviews the current knowledge on 1,5-AG related to its use as predictor for cardiovascular events.
Effects of Aronia melanocarpa on Cardiometabolic Diseases: A Systematic Review of Quasi-Design Studies and Randomized Controlled Trials
Authors: Christiansen Christine B. , Mellbye Fredrik B. , Hermansen Kjeld , Jeppesen Per B. , Gregersen Søren
Published: July 2022

OBJECTIVES: Aronia melanocarpa (Aronia) is a shrub with small berries, chokeberries. Chokeberries are claimed to possess health benefits due to a high content of polyphenols. Aronia is known to be extremely antioxidant; however, evidence for its health benefits is not established.
This review gives an overview of the impact of Aronia on cardiometabolic risk factors and diseases. METHODS: Seventeen studies on cardiometabolic risk factors and diseases were identified through a systematic search on PubMed, Embase, and Cochrane. Inclusion criteria were studies with
Aronia as intervention, performed in individuals with cardiometabolic disease or risk factors, e. g., type 2 diabetes (T2D), cardiovascular disease, hypertension, dyslipidaemia, impaired glucose tolerance, overweight, central obesity and smoking. Four of these studies were applicable for a
quantitative analysis. RESULTS: Aronia did not influence body weight, circulating triglycerides, total cholesterol, high-density lipoprotein (HDL) cholesterol, or blood pressure. The quantitative analysis revealed a mean reduction in blood glucose of 0.44 mmol/l (P=0.0001) in the treatment
group compared with the control group suggesting that Aronia treatment may have a beneficial impact on blood glucose. In addition, treatment durations of 6 weeks to 3 months tended to decrease low-density lipoprotein (LDL) cholesterol, while shorter treatment durations had no effect on LDL
cholesterol. The quantitative analysis did not provide data on long-term effects of Aronia on lipids. CONCLUSIONS: More long-term high-quality randomized controlled studies are needed to clarify if dietary supplementation with Aronia has beneficial effects on cardiometabolic diseases.

Identification of acceptable approaches for assessing key ecosystem services for the Komi Republic forest management area has been the purpose of the study. The forest sector is extremely important for the economic well-being of the region. In this regard, indicators of key services of forest ecosystems are considered and determined – biodiversity conservation, water protection and water regulation functions, and carbon dioxide absorption capacity. Two approaches are proposed for the measuring: regional (by forestry and districts) and corporate (by small river basins). The regional approach uses information from the Red Book of Russia and the Komi Republic, statistics, information on the forest management of forestries and the state of the environment in the region. The corporate one is based on more detailed indicators: the area of forests of high environmental value and key biotopes; quality characteristics of forests of small river basins on a rental area. The natural capital accounting should be the basis for the effective use of natural assets and for responsible and sustainable forest management.

Gorengan merupakan makanan yang dibuat dengan cara digoreng menggunakan minyak. Gorengan juga menjadi makanan yang cocok bagi mahasiswa yang memiliki jadwal padat untuk menahan rasa lapar sementara, meskipun, gorengan juga tidak baik jika dikonsumsi berlebihan. Penelitian ini menganalisis tentang pespektif mahasiswa terhadap perilaku mengonsumsi gorengan, dengan menggunakan metode deskriptif kualitatif. Peneliti menggunakan purposive sampling untuk mendapatkan data dari 11 informan yang merupakan mahasiswa yang pernah mengonsumsi gorengan. Hasil dari penelitian ini adalah mahasiswa mengetahui bahwa gorengan mengandung lemak yang dapat menyebabkan obesitas dan penyakit, misalnya penyakit kardiovaskular, stroke, dan hipertensi. Meskipun mahasiswa mengetahui bahwa minyak yang digunakan untuk membuat gorengan tidak sekali pakai, mahasiswa masih mengonsumsi karena faktor personal, biologis, dan ekonomi, karena gorengan adalah kudapan yang memiliki rasa yang enak, harganya yang murah, dan dapat memberikan rasa kenyang sementara. Namun, ada juga mahasiswa yang membatasi mengonsumsi gorengan karena menjaga tubuh agar tidak gendut sehingga merusak penampilan.

Authors: Anran Yi
Published: July 2022

Introduction. The issue of the relevance of distance education has been studied by various researchers for several decades, since the general digitalization of society. Since 2019, after the start of the COVID epidemic, this issue has become particularly relevant in all areas of education, including the study of foreign languages. In the period 2019–2020, teachers of Chinese and Russian universities actively developed new distance programs that take into account both the peculiarities of learning with the help of modern equipment and technologies, and the difficulties of learning Chinese by students of Russian universities.

Purpose setting. For several years, the system of distance learning Chinese language for students of Russian universities has changed significantly. At this time new programs are being developed, modern platforms and applications are being used, and interactive learning methods are being introduced. It is necessary to identify all the features of distance education.

Methodology of the study. To conduct this study, we used such methods as: the study of theoretical literature and the analysis of practical experience.

Results. As a result of the study, a number of both advantages and disadvantages were identified in relation to the distance education system. In general, the new system differs from standard full-time education, but, despite all its technological difficulties, it can become one of the most effective education systems.

Conclusion. The Chinese distance education model, despite all the difficulties, is actively developing, trying to meet the world’s needs. And the main advantage is that students from different regions can easily communicate, discussing exciting issues of linguistic features and culture of the ancient country of the East. But it will take a long time for this education system to become «ideal».
