Authors: Chairatsiripong Chonjaroen , Yambangwai Damrongsak , Thianwan Tanakit 
Published: July 2023

Abstract
In this article, weak and strong convergence theorems of the M-iteration method for 𝒢-nonexpansive mapping in a uniformly convex Banach space with a directed graph were established. Moreover, weak convergence theorem without making use of Opial’s condition is proved. The rate of convergence between the M-iteration and some other iteration processes in the literature was also compared. Specifically, our main result shows that the M-iteration converges faster than the Noor and SP iterations. Finally, the numerical examples to compare convergence behavior of the M-iteration with the three-step Noor iteration and the SP-iteration were given. As application, some numerical experiments in real-world problems were provided, focused on image deblurring and signal recovering problems.
Ekokritiska perspektiv i Maria Parrs Keeperen og havet
Authors: Axelsson Marcus , Lindgren Charlotte 
Published: July 2023

Abstract
In the present study, we investigate how the relationship between human and nature is rendered as Norwegian children’s book author Maria Parr’s novel Keeperen og havet [Lena, the Sea and me] is translated into Danish, English, French, German, and Swedish. Our focus is mainly on book cover images, and methodologically we use concepts and tools from Kress and van Leeuwen’s Grammar of visual design. Nature and landscape are prominent in Parr’s œuvre, which is set in the Western part of Norway, where mountains and the sea are always present. Results show that the French cover positions itself as the most ecocentric one, whereas the Swedish and the German covers are much more anthropocentric.

AbstractThis report investigates the thermal performance of light-emitting diodes (LEDs) using a heat sink structure based on an optimized design and a sprayed cuprous oxide (Cu2O) coating. An orthogonal array of 18 aluminum plates with various heat-dissipated structures was created. The optimal junction temperature of the LED package is determined by using the signal-to-noise ratio (S/N) of the heat-dissipated structure based on Taguchi’s method as well as the heat dissipation coating. According to the analysis of variance, the most important factors that influence the junction temperature can be obtained as the depth of groove, the layout of holes, the layout of LEDs, and the number of Cu block. These significant factors constituted approximately 91.06% of the variation in the experiment. The results show that by optimizing the structure of the LED heat sink based on the heat-dissipated coating, the efficiency of the junction temperature is increased by 23.88%. Also, a gain of 1.30 dB corresponds to a 9.67% reduction in variance, which indicates the improvement through the optimal setting by 1.162 times of variance, showing good reproducibility. Overall, the coating is based on the optimized design of the structure of the heat sink that has good heat transfer capability, which can provide a good solution to the heat-dissipated problem of LED and further give guidance to the future development of LED.
Efficient and flexible mediation analysis with time-varying mediators, treatments, and confounders
Authors: Díaz Iván , Williams Nicholas , Rudolph Kara E. 
Published: July 2023

AbstractUnderstanding the mechanisms of action of interventions is a major general goal of scientific inquiry. The collection of statistical methods that use data to achieve this goal is referred to asmediation analysis. Natural direct and indirect effects provide a definition of mediation that matches scientific intuition, but they are not identified in the presence of time-varying confounding. Interventional effects have been proposed as a solution to this problem, but existing estimation methods are limited to assuming simple (e.g., linear) and unrealistic relations between the mediators, treatments, and confounders. We present an identification result for interventional effects in a general longitudinal data structure that allows flexibility in the specification of treatment-outcome, treatment-mediator, and mediator-outcome relationships. Identification is achieved under the standard no-unmeasured-confounders and positivity assumptions. In this article, we study semi-parametric efficiency theory for the functional identifying the mediation parameter, including the non-parametric efficiency bound, and was used to propose non-parametrically efficient estimators. Implementation of our estimators only relies on the availability of regression algorithms, and the estimators in a general framework that allows the analyst to use arbitrary regression machinery were developed. The estimators are doubly robust,n\sqrt{n}-consistent, asymptotically Gaussian, under slow convergence rates for the regression algorithms used. This allows the use of flexible machine learning for regression while permitting uncertainty quantification through confidence intervals andpp-values. A free and open-sourceRpackage implementing the methods is available on GitHub. The proposed estimator to a motivating example from a trial of two medications for opioid-use disorder was applied, where we estimate the extent to which differences between the two treatments on risk of opioid use are mediated by craving symptoms.
Very severe hypertriglyceridemia complicating pediatric acute lymphoblastic leukemia treatment: a call for management guidelines
Authors: Baxter Carly L. , Martin Elise G. , Marwa Bilal M. , Pacaud Danièle , Cummings Elizabeth A. 
Published: July 2023

Abstract

Objectives
Severe and very severe hypertriglyceridemia although rare within the pediatric population occur more often among oncology patients, secondary to chemotherapeutic agents. Currently there exists minimal literature to guide management of severe hypertriglyceridemia among pediatric patients. Very-low-fat dietary restriction should be considered over nil per os (NPO) for initial management of severe hypertriglyceridemia in stable pediatric patients. Pediatricians caring for oncology patients must consider chylomicronemia as a potential etiology for presenting symptoms. Pediatric severe hypertriglyceridemia management guidelines are needed as pediatricians must currently rely on anecdotal experiences for management decisions.

Case presentation
Three children receiving treatment for acute lymphoblastic leukemia required hospitalization for very severe hypertriglyceridemia. Management varied among the cases but included: NPO or very-low-fat diet, insulin, intravenous fluids, fibrates, and omega-3 fatty acids.

Conclusions
These cases suggest that pediatric severe hypertriglyceridemia management, in the absence of pancreatitis should allow a very-low-fat diet initially rather than NPO followed by pharmacologic therapies.

Miradas al vacío: la artificialidad de los discursos fundacionales. Hacia una lectura de Álvaro Enrigue
Authors: Sánchez Martínez Francisca 
Published: July 2023

«¿Cómo es que hemos construido toda una épica si la Nación es un puro artificio?». Este es uno de los interrogantes que resuenan en la obra del mexicano Álvaro Enrigue, cuyas ficciones dejan al descubierto lo que de relato, de artificio, poseen los cimientos sobre los que se sustentan identidad y tradición. A través del análisis de dos de sus novelas, El cementerio de sillas y Muerte súbita, intentará mostrarse cómo el autor se sirve de recursos como la ironía, la parodia o la autoconsciencia para cuestionar la autenticidad de esos discursos de legitimación que ostentan el carácter de verdad única.Palabras clave: discurso, identidad, ironía, desmitificación

La reflexión sobre la corrupción y el poder que realizara William Shakespare con Macbeth encuentra, en diversos contextos, interesantes revisiones que proponen nuevos focos de interés. En este estudio nos acercaremos a dos propuestas argentinas de esta tragedia, las cuales nos permiten percibir el diálogo con la obra canónica y, a su vez, comprobar las variaciones ejercidas en relación a los diferentes contextos de producción: Macbeth (1980) de Carlos Somigliana, durante la dictadura autodenominada Proceso de Reorganización Nacional (1976-1983), y La señora Macbeth (2002) de Griselda Gambaro, bajo la estela de la posdictadura.Palabras clave: Macbeth; Dictadura; Posdictadura; Somigliana; GambaroFrom Dictatorship to Post-dictatorship: Variations on Macbeth in Argentine theatreAbstract: William Shakespeare’s reflection about corruption and power in Macbeth contexts gives rise to evocative revisions of the text in different contexts, generating new points of interest. In this paper we will analyse two Argentinian versions of this tragedy allowing us to look at the dialogue with the canonical playwright and to explore their variations depending on their contexts of production: Macbeth (1980) by Carlos Somigliana, written during the dictatorship known as Proceso de Reorganización Nacional (1976-1983), and La señora Macbeth (2002) by Griselda Gambaro, in the posdictatorship era.Key words: Macbeth, Dictatorship; Posdictatorship; Somigliana Gambaro
Altas capacidades en adultos

Published: July 2023

En los estudios más recientes en altas capacidades se señala la importancia de identificar para atender las necesidades educativas. De esta manera, después del proceso de identificación, hay que proporcionar una respuesta educativa, a través de un programa de enriquecimiento intraescolar, o sea dentro de la escuela, o extraescolar, fuera de la escuela. Así, la presente investigación tuvo como objetivo, en primer lugar, analizar quién diagnosticó la alta capacidad en los participantes, en según qué edad recibió un diagnóstico, y en tercer lugar, qué respuesta educativa recibió durante la vida escolar. La investigación fue descriptiva con análisis cualitativo. El cuestionario fue contestado por 217 adultos con altas capacidades. Así, se ha podido comprobar que más de la mitad de los diagnósticos recibidos proceden de Mensa (50,6%), seguidos de psicólogos (25,8%) y de los centros educativos o psicólogos escolares (11%). Acerca de las edades, 80% de la muestra fue diagnosticada con altas capacidades en la edad adulta, destacando las edades entre 21-25 años, seguidos de 31-35 años y 26-30 años. En ese marco, cabe enfatizar que sólo 17 participantes (7,9%), recibió algún tipo de respuesta educativa durante su vida escolar. Estas respuestas se dividieron en respuestas intraescolares, extraescolares y para adultos. Sin embargo, los resultados son alarmantes, ya que muestran la invisibilidad de estas personas en cuanto a una identificación y respuesta educativa en la enseñanza básica. Esto provoca, que la ausencia de evaluación e intervención temprana puede no ofrecer propuestas y cuidados diferenciados que puedan satisfacer las necesidades específicas de desarrollo de la persona con altas capacidades, lo que puede conducir a la inhibición de su potencial.
Was the Tale a Women's Genre? Tellers, Collectors, and Writers of Tales in 19th-Century Hungary
Authors: Gulyás Judit 
Published: July 2023

AbstractIn 1858 a leading Hungarian literary critic as well as collector and editor of folk poetry started a debate about the possible literary career of women, arguing that literature and other forms of public artistic activity are fields that should not be open to women as it may cause serious moral and social problems. Yet, he noted that in case women still insist on becoming literary authors, they should turn only to certain genres, such as tales. The article investigates how the tale became a gendered genre, and presents women tellers, collectors and writers of tales as well as the diverse ways they were represented in Hungarian culture in the 19th century.

High sulfate content in seawater forms sulfate salts, which become impurities in sea salts. This study investigates the influence of lime juice in the adsorption of sulfate ions in seawater using commercial activated carbon. A full factorial experimental design was employed to optimize the level factors of activated carbon type, adsorbent dosage, and concentration of lime juice in response to the percentage reduction in sulfate concentration. Activated carbon (GCB) and acid-washed activated carbon (GCA) were two types of coconut shells granular activated carbon used for the experiment without further modification. The main effect and interaction effects were analyzed using analysis of variance (ANOVA) and p-values to define the influence of variables affecting sulfate ions adsorption. The adsorption of sulfate ions in seawater was affected by the interaction between the activated carbon type and the dosage, and the concentration of lime juice. The lime juice factor significantly enhanced the performance of activated carbon to adsorb the sulfate ions in seawater, and the factor's contribution was 58.2 %. The optimum sulfate ions reduction from seawater was attained at levels of factors activated carbon GCB, the dosage of 50mg, and the concentration of lime juice 50 µl. The interaction between lime juice and activated carbon pores are electrostatic. The impurities are attracted by the revealed polarity of the activated carbon pores. High electronegativity of lime juice acid pulls the negatively charged ions of the impurities. The more economical activated carbon, GCB, which performed better in sulfate ion adsorption, provides an alternative for reducing sea salt impurities. Hence, GCB can directly be mixed with the seawater to produce high quality sea-salt. Therefore, this study is suitable to improve sea salt product quality that processed with activated carbon

The research of the influence of teff flour on the technological process and quality of wheat bread was present in the article. The analysis of the chemical composition of teff flour indicated, that it is a valuable raw material for enriching wheat bread. However, its dosage in the quantity of 10 and 20 % to the weight of wheat flour leads to decrease in the amount, springy and extensibility of gluten in the dough. Alveograph studies also confirmed that dosage of 20 % of teff flour the most decreases springy of the dough and it becomes more plastic.
The improvement of the structural and mechanical parameters of bread with teff was applied the biotechnological method of preparation on sourdough that created on the pure cultures of lactic acid bacteria “Biolight”. The experimental studies were proving that utilizing of teff flour in the quantity of 10 % and sourdough improved both the quality and nutritional value of wheat bread. In particular, the specific volume of bread increased by 4.0 %, acidity ‒ by 2.9 % compared to the control; and the product was distinguished by a pleasant "nutty" taste and aroma. Close correlations between the percentage of teff addition and the spread of the dough ball were established, r=0.98 (n=10, p≤0.05) and the form stability of the bread, r=(‒0.95) (n=10, p≤0.05). It allowed establish that wheat bread with teff addition need to make in the mould.
It was calculating that consumption of the daily norm of bread with 10% teff the consumer will be receiving a sufficient quantity of valuable food nutrients. Thus, the need of protein was covered by 42.9 and 49.8 %; iron ‒ by 32.3 and 28.5 %; vitamin B5 ‒ by 17.6 and 24.2 %, respectively, for men and women; and the need for phosphorus ‒ by 26.7 %, for both groups.
The technology of wheat bread with teff of high quality for mass consumption that recommended for wide industrial implementation has been develop

The object of research is the technology of creamy-whipped sweets with the addition of fruit and berry paste. Its addition solves the problem of improving sugar masses, namely structural characteristics and physiological value (enrichment with non-starch polysaccharides, vitamin C, polyphenols, and organic acids). In addition, a positive effect is achieved by providing the products with original organoleptic properties without the use of synthetic dyes and flavors. The proposed fruit and berry paste is obtained at gentle temperatures, which allows preserving the biological potential of raw materials and is characterized by a strong structure with a dynamic viscosity of 498 Pa·s.
It was found that the introduction of fruit and berry paste in the amount of up to 10 % by weight of formulation raw materials improves the foaming ability of protein mass in the process of whipping. Increasing the paste content to 20 % leads to a slight deterioration in this indicator, but its value is at the level of control. The stability of the whipped protein mass increases evenly by increasing the dosage of the additive. The positive effect of fruit and berry paste on the quality indicators of finished creamy-whipped candy masses was noted. Samples with the additive give less shrinkage during the structuring process, its duration is reduced, and strength increases. It is recommended to add fruit and berry paste to creamy-whipped candy masses in the amount of 15 % of the total amount of formulation raw materials and at the same time reduce the formulation dosage of agar by 40 %. Such products acquire an original lilac color, a pleasant yogurt flavor, and the aroma of red currant. The nutrient composition of products is significantly improved – the content of non-starch polysaccharides increases by 2 times; the product is enriched with vitamin C and polyphenolic compounds that are absent in the control sample

The object of the study is the period of induction of accelerated oxidation of oil solutions of fat-soluble dyes chlorophyll and beta-carotene. The effect of the content of fat-soluble dyes on the period of induction of accelerated oxidation of their solutions in refined sunflower oil was studied. The peculiarity of the work consists in establishing approximate graphic and mathematical dependences of the term of the induction period of accelerated oxidation of refined sunflower oil on the content of chlorophyll and beta-carotene separately and together. This is important for predicting the shelf life of oil solutions of fat-soluble dyes.
It was determined that chlorophyll A practically does not show a pro-oxidant effect if its content is up to 0.05 g/l. The content of chlorophyll A at the level of 0.10 g/l leads to a reduction in the duration of the induction period by 14 %; 0.20 g/l – by 36 %; 0.30 g/l – by 48 %. The content of beta-carotene at the level of 0.10 g/l leads to an increase in the duration of the induction period by 35 %; 0.20 g/l – by 47 %; 0.30 g/l – by 54 %. The content in the oil system of 0.10 g/l of beta-carotene and 0.05 g/l of chlorophyll A leads to a reduction in the period of induction of accelerated oxidation by 8.4 % compared to the oil solution of 0.10 g/l of beta-carotene without chlorophyll A. The obtained data are explained by the fact that there is a compensatory effect of the antioxidant beta-carotene on the pro-oxidant effect of chlorophyll A in the oil solution. A feature of the obtained results is the possibility of predicting the shelf life of oil solutions of fat-soluble dyes. From a practical point of view, the results of the research allow to develop oil systems taking into account the separate and compatible features of reactivity to the oxidation of chlorophyll and beta-carotene. An applied aspect of using the scientific result is the possibility of expanding the assortment of oil products of increased nutritional value with different contents of chlorophyll and beta-carotene
