Optimization of the rhomboidity of continuously cast billets using linear regression and genetic programming: A real industrial study
Authors: Kovacic M. , Zuperl U. , Brezocnik M.
Published: December 2022

During the continuous casting of steel billets, several geometrical, inner and surface defects can occur due to the thermomechanical behavior during solidification. One of them is rhombic distortion (i.e. rhomboidity), which can lead to the occurrence of off-corner cracks and twisting of cast billets during further plastic deformation (i.e. rolling). Based on data of 2088 cast batches (64 different hypoeutectoid steel grades), 109,514 billets, produced from January 2022 to September 2022 in Štore Steel Ltd. (Slovenia), chemical composition (content of C, Si, Mn, S, Cr, Mo, Ni and V), casting parameters (average casting temperature, average difference between input and output cooling water, melt level, average cooling water flow and pressure in the first and second zone of secondary cooling) the linear regression and genetic programming were used in order to predict rhomboidity of continuously cast billets. The rhomboidity, in our case defined as relative diagonal difference, was determined using in-house developed computer vision system for measuring of rhomboidity. Based on the modelling results 9 batches (419 billets) of 42CrMos4 were cast in September 2022 with a 10 % higher water pressure in the first zone of secondary cooling (from 2.41 bar to 2.67 bar). The rhomboidity of continuously cast billets improved by 18.18 % (from 1.43 % to 1.21).

Published: December 2022

Dielectric sensors are a popular choice for determining wood moisture content. However, the output of these devices, especially when measuring high moisture content, may be significantly affected by the moisture content itself, by sensor frequency (f) and by environmental temperature (T). This study investigated the effect mechanism of f and T on dielectric properties of wood with different moisture contents. Dielectric constant (ε) and dielectric loss factor (tan δ) for Populus nigra, Tilia tuan, Abies fabri and Fraxinus mandshurica wood samples of various moisture contents were measured from 1 to 107 Hz and from – 40 to 25 °C. The results show that wood ε increases with increasing moisture content and temperature, and decreases with increasing f. The dielectric constant depends significantly on f when T exceeds 6 °C, the rate of ε decreases with increasing f. At room temperature, tan δ of wood with moisture content >50% were not related, and peaked between 103 and 104 Hz. The change of tan δ with T is complex. The results provide a basis for in-depth research on the dielectric properties of wood with high moisture content and a theoretical basis for the measurement and calibration of the moisture content of standing trees.

Authors: Ariyanti Agni Lili , Chien Mei-Fang , Inoue Chihiro
Published: January 2023

This study focuses on how to solve cadmium (Cd) contamination in soil because this contaminant decreases soil quality. Soil remediation using the hyperaccumulator plants is an optional process to solve soil contamination. Arabidopsis halleri ssp. gemmifera (hereinafter referred to as A. halleri), is one of the candidate plants expected to be used for phytoremediation of Cd contaminated soil. The A. halleri promote solubilization of Cd in the soil directly or indirectly using its secreted root exudate. However, the effect of the metabolites profile of this plant to Cd uptake from contaminated soil is still unclear. The purpose of this study is to examine the contribution of root exudates of A. halleri to extract Cd in the soil. Cd-contaminated soil used in this study was a farmland soil containing 5.8 mg kg-1 of Cd and 648 mg kg-1 of Zn taken from Tome City, Miyagi Prefecture, Japan. Soil leaching tests were conducted using the solution containing the root exudates from A. halleri plant. The accelerating effect of root exudates of A. halleri on solubilization of Cd is fundamental information to construct the benefit of phytoremediation.

Published: January 2023

ABSTRACT – The Immigration Department of Malaysia, being the first line of defense, has always been in the limelight for its success stories as well as its flops due to integrity, system, and management issues. The debatable issue in Integrated Border Crossing Management (IBM) is the difficulty for any immigration operator to maintain balance with compliance requirements. Thus, the Department needs to keep in line with the fast-emerging threats by having proper planning to keep the Department strong in the challenging emigrational environment. An IBM system commonly refers to the number of agencies manning multiple authorizations in border crossing examinations that involve the examination of people and goods. Most of the previous research has been limited to studies and limited data on the topic. Bukit Kayu Hitam and Padang Besar have traditionally operated to accommodate the locals and have expanded to be among the most challenging entry points due to their accessibility to multiple irregular activities. Thus, the aim of this research is to study the current implementation of the border crossing management system in managing the border between Malaysia and Thailand. Moreover, to suggest countermeasures to reduce the implementation gaps in managing the border between both countries, as the increasing gaps may lead to management issues. The research was conducted using a qualitative method (semi-structured interviews and ATLAS.ti 22 software), with results indicating that three major themes emerged which are Policy, Current Technology Adoption, and Border Crossing Management are factors that influence cross-border management. This illustrates the importance of having an efficient control module that reflects the smoothness of the border crossing process while maintaining national security and providing a decent examination experience to attract potential investors or business opportunities for Malaysia.

Published: December 2022

The article deals with the problem of preparing students for the formation of the natural science foundations, including ecological literacy, which is relevant for a pedagogical university. The solution to this problem is proposed to begin with increasing the natural science literacy of the students themselves, since testing has shown the level of it among first-year students is relatively low. The experience of organizing theoretical training of future bachelors of primary education within the disciplines of the natural science cycle is described. Training should be based on correct scientific information about all levels of the organization of matter, use different forms and methods: the study of natural objects and their models in laboratory conditions, excursions, independent search for information in various sources, its critical analysis. Methodological training is recommended to be carried out based on the available published materials on functional literacy, the study of which facilitates the design of diagnostic tasks, conducting model lessons in practical classes at the university and preparing for lessons taking into account the requirements of the Federal State Educational Standard on pedagogical practice. Independent research in the preparation of term papers and final qualifying papers, writing articles, as well as participation in conferences, subject olympiads and competitions contribute to the development of creative thinking of students. The majority of senior students demonstrate a higher level of natural science literacy than at the beginning of their education at the university.

Published: December 2022

The article deals with the problem of integration and adaptation of the disciplines of the psychological, pedagogical and subject blocks in the process of preparing a teacher-choreographer in a pedagogical university. The concept of “integrationˮ in science has been clarified. A theoretical substantiation of the importance of having the psychological and pedagogical training of a teacher-choreographer equally with special training, as a single educational process in a pedagogical university, is given. The characteristics of these two areas of training are given and the need for their interdisciplinary connection is argued. As a result of scientific and theoretical analysis, it was concluded that the educational process in a pedagogical university and in modern social conditions cannot be limited to borrowing the cultural component from universities of culture and art, and the pedagogical component remains identical to non-creative teachers, therefore, a detailed study of the methodological part is relevant. the issue of integration of psychological, pedagogical and special training in relation to the choreography teacher. At the same time, it is noted that the integration in the educational process of a teacher-choreographer in a pedagogical university is a process, and the result of this process is the ability of a specialist to adapt and apply the means and methods of general pedagogy and psychology in practical choreographic activities.

Authors: Masruroh Imas , Badriah Siti , Erihadiana Mohamad , Ruswandi Uus
Published: December 2022

Majelis taklim is a non-formal educational institution whose followers are called non-student congregations. This is because the taklim assembly is a place for Islamic education that is not required as well as school students. The Ta'lim Council is recognized as one of the institutions that can encourage the realization of multiculturalism among Muslims. However, recently the Ta'lim Council has been accused of being one of the centers for the spread of religious radicalism. The multicultural, multiracial, and multireligious Indonesian society has a great potential for conflicts between groups, races, religions and ethnicities. On that basis, it is necessary to have a large role for educational institutions in developing learning models and developing the Multiculturalism Curriculum. The author conducted research on this matter at the Sakinah Ta'lim Council, Bandung City. This study uses a qualitative approach with analytical descriptive method. The results showed that the learning model applied in the Sakinah Ta'lim Council was a multicultural learning model that was not designed as a whole, but an insert model that was integrated into the learning material.

Published: December 2022

A mother is seen as the main actor in taking care of children and household chores. Currently there has been a shift in values  that provide opportunities for women to enter the world of work. These conditions can potentially cause problems in parenting for working mothers. This study aims to explore the problems in parenting experienced by working mothers. This study uses a qualitative phenomenological method to find out what problems working mothers experience in raising children. The participants in this study were eight working mothers (work as lecturers) aged 20-40 years, have toddler and lived with their husbands and children in one house. The motivation of mothers who continue to work even though they are caring for children include: economic factors, hobbies, and self-development. These conditions contain benefits and risks that must be faced by working mothers.  From the results of research and discussion, it can be seen that the biggest problems in caring for working mothers are: 1) Time management,  working mothers experience challenges such as managing time, having difficulty fulfilling their responsibilities as a mother, and managing workplace issues. The average informant works as a lecturer for at least 8 hours per day in the office and returns to do additional assignments at home for which there is no definite time limit. Mothers also still have duties to serve the family at home including caring for children and resting. This division of time is considered difficult by working mothers. 2) Managing emotions, fatigue from serving work and family makes the mood unstable. If support from the environment is minimal, this can trigger stress and burnout in working mothers. This condition can cause excessive anger, sadness and anxiety. 3) Health problems, connected from the problem of managing emotions, health problems can also arise when the mother is too tired and lacks rest. some of the health problems that often occur in working mothers: dizziness, fever, pain in the bones, stomach ulcers, stress and depression. 4) Family conflicts,the busyness of the mother outside the home makes the mother's duties at home not carried out perfectly. the need for support from people around so that conflicts in the family do not occur. Conflicts that can occur include: misunderstandings, ambiguity in the duties of family members, and attachment problems between mother and childrens.

Authors: Jazuli Muhammad , Suharji Suharji , Pebrianti Sestri Indah
Published: December 2022

The aim of this research is to find out the specifications of the choreographic form and the symbolic meaning of wirèng in the Kasunanan Palace. A qualitative descriptive research design with form-matching techniques was employed; meanwhile, the data collection techniques employed observation, interviews, and literature study. The data analysis includes the form of the wirèng choreography and its symbolic meaning. From the results of the study, it was found that the choreographic form of wirèng in Kasunanan was used for pair dances and had a soldier’s theme, while in Mangkunagaran wirèng was used to denote the term dance because wirèng is synonymous with the word beksan which means dance. The pattern of the wirèng choreography in Kasunanan has specifications, namely: (1) it is performed by male and female dancers in an even number, (2) it consists of three parts, namely the initial part (maju beksan), the main part (beksan), and the final part (mundur beksan), (3) in the main part of the dance there are variations of the dance scenes and variations of war scenes, such as madras wars or gending wars, referring to a typical war dance which is accompanied by slow (lamba) and constant (steady) rhythmic gendhing or music, and ruket wars which are accompanied by fast-rhythmic pieces of music (mipil-lancaran), (4) changes and differences always follow every change of part in the composition of the accompaniment pieces. Wirèng’s symbolic meaning reflects the value system prevailing in the palace environment, symbolized by the numbers zero, two, and three, movement characteristics, and movement patterns (gawang) in the choreography.
Analysis of the Thinking Process of Science Teachers: The Light Absorption Thought Experiment
Authors: Uyar F K , Karamustafaoğlu O
Published: December 2022

The aim of this research is to investigate the thinking processes of science teachers who are master students in science education regarding the thought experiment designed for the light absorption. For this aim, the phenomenological study method, one of the qualitative research designs, was used. In the study, eight science teachers who were continuing their master were studied by using purposive sampling. Data were collected through interviews on the light absorption thought experiment. Data were collected through face-to-face problem-solving sessions, thinking aloud and backward questioning. From the data, it is seen that the teachers mostly showed secondary effects as establishing a new amount relationship, they carried out thought experiments to conviction, and while they preferred scientific concepts and intuition-based simulations as sources of thinking equally, spatial reasoning-symmetry-compound simulation and experience were preferred equally and less frequently. At the end of the research, it was concluded that the self-efficacy perceptions of the science teachers were high, having a command of the curriculum, having an uneasy mood when solving problems, and having hypothetical thinking skills.

Authors: Babenko V.F. , Parfinovych N.V. , Skorokhodov D.S.
Published: December 2022

We solve the problem of the best approximation of closed operators by linear bounded operators in Hilbert spaces under assumption that the operator transforms orthogonal basis in Hilbert space into an orthogonal system. As a consequence, sharp additive Hardy-Littlewood-Pólya type inequality for multiple closed operators is established. We also demonstrate application of these results in concrete situations: for the best approximation of powers of the Laplace-Beltrami operator on classes of functions defined on closed Riemannian manifolds, for the best approximation of differentiation operators on classes of functions defined on the period and on the real line with the weight $e^{-x^2}$, and for the best approximation of functions of self-adjoint operators in Hilbert spaces.

On a nonlocal problem for the first-order differential-operator equations
Authors: Horodets'kyi V.V. , Martynyuk O.V. , Kolisnyk R.S.
Published: December 2022

In this work, we study the spaces of generalised elements identified with formal Fourier series and constructed via a non-negative self-adjoint operator in Hilbert space. The spectrum of this operator is purely discrete. For a differential-operator equation of the first order, we formulate a nonlocal multipoint by time problem if the corresponding condition is satisfied in a positive or negative space that is constructed via such operator; such problem can be treated as a generalisation of an abstract Cauchy problem for the specified differential-operator equation. The correct solvability of the aforementioned problem is proven, a fundamental solution is constructed, and its structure and properties are studied. The solution is represented as an abstract convolution of a fundamental solution with a boundary element. This boundary element is used to formulate a multipoint condition, and it is a linear continuous functional defined in the space of main elements. Furthermore, this solution satisfies multipoint condition in a negative space that is adjoint with a corresponding positive space of elements.

Publishing National Cultural Periodicals in Lithuania: A Reflection of Cultural Functions in 2000–2015
Authors: Urbanavičiūtė-Globienė Asta
Published: January 2023

Cultural periodicals, as a specific part of the field of culture and publishing, can be studied in several directions: 1) by analysing the conceptual aspect of cultural periodicals, i.e., realisation of their cultural functions; 2) by taking into account the general models of publishing periodicals; 3) by analysing other aspects of publishing that are specific to cultural periodicals only, for example, the specific features of funding. This article analyses how the cultural functions of national periodicals were realised in the context of the virtualisation of cultural periodicals in the period under research (in 2000–2015). (In this article, the virtualisation of cultural publications is understood as the transfer of cultural periodicals (magazines, newspapers) into the virtual space or their creation in that space (blogs, portals, social networks)). Cultural periodicals as a part of the cultural field were relevant in the period under research: 1. It is relevant to transmit and preserve cultural information (in this case, the communicative link between the cultural message and the cultural space and the lasting value of cultural texts); 2. To form new addressees to receive the cultural message (each publication brings together its own audience and thus complements the overall cultural field, thus attracting new readers by disseminating cultural information); 3. To actualise the message being sent through more diverse channels (the importance of internationality), to expand the possibilities of accessibility and availability of cultural texts; changes in the media (social networks, portals, websites) have created a broader, more modern and more diverse cultural field of communication. Between the years 2000 and 2015, media change gradually turned into a necessity. First of all, it was undertaken as a way to reach more readers. Due to the specific content, cultural publications were moderate in their approach to the changes in form during the period under analysis: to maintain a high-quality printed version was a priority to them. On the other hand, cultural publications, although not always willingly, began to recognize the importance of the Internet and to consider it as a platform for disseminating cultural information. This aspect became an important turning point in the publishing of cultural periodicals.

Transforming communities: an analysis of the Nigerian educational landscape
Authors: Ashimem Angya Charity
Published: December 2022

The paper addresses the disparities in the educational landscape of Nigeria through contrasting the current realities of funding against the needs of education from pre-primary, primary, secondary and tertiary needs of the educational sector in Nigeria. Building on existing studies, the paper contends that there are gaps that have led to the sad decline of quality in education. Issues such as adequate educational facilities, truncated policy implementation, funding, inadequate infrastructure, quality of teaching and research, pedagogy and current demands for up to date curriculum to meet the demands of the market, student attitudes and motivation, digitalization and other factors have affected the educational system in Nigeria. The paper concludes that there is a need for sustained funding, quality policy design and implementation and commitment to challenging the status quo in order to effectively deliver quality education.
Hierarchical self-assembly in ionic liquid crosslinked polyelectrolyte gels as a citric acid sensor
Authors: Kumar Pandey Pankaj , Rawat Kamla , Aswal VK , Kohlbrecher J , Bohidar Himadri B
Published: December 2022

The design of an enzyme-free biocompatible electrochemical platform for the detection of citric acid is discussed. We have studied sol-gel transition in DNA ionic liquid solution triggered by the ionic liquid (IL), (1-Octyl-3-methylimidazolium Chloride [C8mim][Cl]; concentration= 0.1 to 1.0% (w/v)). Rheology and Small-angle neutron scattering (SANS) studies characterized their viscoelastic and microstructural properties. The gel modulus was found to vary from 10 to 60 Pa concomitant with a tunable temperature of gelation. SANS data yielded the persistence length of DNA (50 ± 12 nm) and the mesh size of these gels (ξ = 2.5±0.5 nm). Remarkably, this ionogel served as an excellent electrochemical sensor for citric acid detection in the application window of 0.02-0.08 mM analyte concentration with a detection limit of 1.510-8 molL-1. Yet another non-trivial application of the versatile DNA gel is demonstrated here.

In the soil, it inhibits the mineralization of organic matter causing loss of fertility. Therefore, the aims of this research a) biostimulation of a soil impacted by 10,000 ppm of GAS, and b) phytoremediation through Zea mays enhanced with Azotobacter vinelandii to decrease the GAS to a value lower than the maximum of the NOM-138-SEMARNAT/SSA1- 2003. In that sense an agricultural soil was impacted by 10,000 ppm of GAS was biostimulated applying a crude fungal extract (CFE)/2 months and vermicompost (VC)/1 month, later it was phytoremediated with Z. mays enhanced by A. vinelandii/2 months; with the response variables phenology and seedling biomass and flowering: The experimental data were validated by ANOVA/Tukey HSDP<0.05%. Results: showed that the biostimulation of the soil impacted by 10,000 ppm of GAS with 60,000 ppm of CV was sufficient to reduce the concentration of GAS, followed by phytoremediation with Z. mays/A. vinelandii at flowering, where 5.79 g of aerial dry weight (ADW) and 2.59 g of root dry weight (RDW) were recorded, numerical values with statistical difference with the 4.49 g ADW and the 2.07 g RDW of Z. mays grown in uncontaminated soil by GAS fed with a mineral solution or relative control, with which soil biorecovery was achieved by decreasing GAS from 10,000 to 500 ppm, a value lower than the maximum allowed by NOM-138-SEMARNAT/SSA1-2003. The biorestoration of a soil impacted by GAS through biostimulation and phytoremediation is slow compared with strong oxidizing chemical agents but is ecological and allowed to reuse soil for agricultural production. It’s concluded that it is possible to biorecover soil contaminated by GAS due ecological and simple strategy.
Double minute chromosomes in Anastrepha fraterculus (Wiedemann) (DIPTERA: Tephritidae): a model for cancer studies
Authors: ESchenone Cecilia , Basso Alicia L
Published: December 2022

Anastrepha fraterculus (Wied.) is known as the South American Fruit Fly. In order to develop efficient control strategies, we need deep knowledge on its biology along with periodical studies on population dynamics. Citogenetic studies on natural populations of this pest fly made it possible to reveal the presence of double minute chromosomes (DMs) in several natural populations of this insect. Cytogenetic studies performed in our insect laboratory, allowed the genetic analysis through a genealogical methodology. The establishment of families made it possible the genetic studies allowing the rigorous identification, characterization and confirmation of new chromosomal variants, frequently missinterpreted when the materials analyzed only come from nature. Double minute chromosomes -considered a type of chromosomal rearrangement- are extra chromosomal gene copies. This study sought to answer: What role do DMs chromosomes play in laboratory populations of the pest derived from natural populations? How are they transmitted from one generation to another? To answer our questions, we analyzed for 25 generations, two laboratory populations derived from Tucuman (T) and Buenos Aires (BA -tester) guava,. Data were recovered from cytological analysis of ganglia preparations revealed with H33258. The natural population from BA didn’t carry DMs. Results showed DMs in flies of both laboratory populations. DMs were transmitted from parents to progenies through 25 generations and their transmission was randomized in number. DMs are the cytological expression of resistance mechanisms used by the pest as a response to environmental stress. DMs in BA strain marked the change to the laboratory environment. A. fraterculus is a model insect for the study of cancer.
Notes on the epidemiology of artificial mechanical ventilation and stroke
Authors: Remón Ariel Sosa , Naranjo Arian Jesús Cuba
Published: December 2022

Artificial mechanical ventilation in the course of stroke presents a high mortality. Even today, with advanced knowledge in the physiopathology of the neurological event and modern techniques of respiratory support, it continues to be a problem of interest, which invites to reflect on the benefits of ventilation in this field. In Cuba, there is not enough research on the subject, however, mortality due to this cause is high. This phenomenon, which implies high costs and limited functional recovery in survivors, should continue to be studied.

In this study, the qualify evaluation of noodles produced from wheat and almond seed composite flour was studied. A preliminary was carried out to ascertain the optimum acceptable level of almond seed flour in wheat flour noodle processing using 0-50%w/w, samples were subjected to sensory evaluation and the most acceptable samples was chosen. Hence, in the main study, level of almond seed flour was varied within the most acceptable level using 5, 10, 15 and 20% w/w inclusion giving rise to four samples. Functional properties, anti-nutrient content, proximate composition, essential amino acid profile, selected mineral content, textural and cooking analyses and sensory evaluation were done using standard methods. The bulk densities of the blend ranged from 0.801 to 0.884 g/ml, WAC, ranged from 2.20g/g to 3.60g/g and swelling index ranged from 6.27 to 2.27 as the proportion of almond seed flour increased from 0-20 %. The values of phytate, oxalate, and tannin range from 0.12 to 0.75g/100g, 0.03 to 0.92g/100g and 0.08 to 1.23g/100g respectively. An increase (9.99 % - 14.55 %) in protein content was observed in the flour blends with increased addition of almond flour, there were significant difference (P<0.05) in mean samples. Lysine value ranged from 3.44 to 5.09%, Valine value ranged from 3.71 to 5.01% and leucine value ranged from 7.06 to 7.24% as the level of almond flour increases from 0 to 20% in the flour blends. Potassium (412.40 mg/100g), magnesium (167.00mg/100g) and calcium (66.55mg/100g) were predominant minerals in the formulated noodles while Iron and sodium were found in low concentration. The values of B1, B2 , B3 ,B6 B9, C, D and E ranged from 1.95 to 2.12mg/100g, 0.45 to 1.12 mg/100g, 0.72 to 0.68mg/100g, 1.25 to 2.12mg/100g, 12.09 to 22.02mg/100g, 19.55 to 22.12 and 0.21 to 2.12 mg/100g respectively as the proportion of almond seed increases from 0 to 20% in the blends used in noodle preparation. The results for length, porosity apparent density and weight for noodle sample from wheat flour (control) were 3.34cm, 0.52mm, 0.87 and 1.94 g respectively. The corresponding values for noodle from 95% wheat flour and 5% almond seed flour were 3.25cm, 0.50mm, 0.89 and 1.93g respectively. . Cooking time and cooking lose increased on addition of almond seed flour while percent rehydration reduced as the quantity of almond seed increased in the noodle samples. Blend formulation 80:20 W : A was mostly acceptable. This study therefore has presented a way of increasing consumption and utilization of almond seed with high nutritional content yet are underutilized increasing food security, providing more affordable noodle from local available food sources and further converts waste to wealth.

Authors: Rizzo Daniele
Published: December 2022

Several cutaneous inflammatory diseases can affect the nails, leading to alterations that can be severe and can determine functional and psychosocial consequences. Lichen planus, a benign inflammatory disorder of not well understood etiology, is one of them. Nail manifestations in lichen planus may be isolated or appear in a more generalized involvement of the skin. Currently nail lichen planus is very difficult to treat, and there aren’t therapies fully accepted by the scientific community. Topical therapy does not lead to significant improvements and intralesional steroids are considered as a first line therapy. I present a case of nail lichen planus involving just one nail of a hand, successfully treated with intralesional triamcinolone acetonide.

Published: December 2022

The work that is presented collects a small sample of older people who participated in a choral group, whose activity was interrupted by covid19. The activities of this group gradually recovered, as the contagions decreased. A series of tests were carried out on a small sample after having resumed musical activity, during the month of March 2022. After the significant increase in infections at the end of December 2022, musical activities were paralyzed and it was measured again with the same tests to the small participating sample in January 2022. The results pointed to the relevant need for musical practice, since the evaluations were much lower in the post test.
