Authors: López-Florit Laura
Published: January 2024

El objetivo de este artículo se centra en reflexionar sobre los procesos de aprendizaje de los alumnos con Trastorno del Espectro del Autismo (TEA) en la etapa de educación primaria (de 6 a 11 años). La metodología que se lleva a cabo se basa en la revisión teórica donde se detalla la importancia de proporcionar una respuesta pedagógica satisfactoria propia a las necesidades educativas particulares. El trastorno del Espectro del Autismo repercute de un modo global al desarrollo cognitivo-social-emocional desde la primera infancia, y su sintomatología repercute individualmente en las distintas etapas evolutivas. La multiplicidad de aspectos cognitivos y conductuales del autismo determina una mente multidimensional. En conclusión, se detalla la necesidad del conocimiento de la individualidad del alumnado con TEA para poder establecer la intervención educativa más adecuada y eficaz, que promueva la calidad de vida del discente con autismo y, por consiguiente, la de sus familias. Desde esta perspectiva, el ámbito escolar se considera un espacio de desarrollo individual y social. Para ello, se precisa que la intervención pedagógica se centra en proporcionar respuestas a las necesidades particulares tanto a nivel académico como a escala cognitivo-social-emocional.

Authors: Valle-Pinedo Yvett Graciela , Nakamura-Goshima Patricia
Published: January 2024

Este artículo explora los estilos motivacionales de las docentes en dos aulas de educación primaria en una institución educativa privada de la ciudad de Lima, dentro del contexto de educación remota llevada a cabo en el período de la pandemia por la Covid-19. Según la Teoría de la Autodeterminación de Ryan y Deci (2000), estos estilos hacen referencia a patrones de acción que se encuentran presentes en las distintas prácticas que realizan los docentes para motivar a sus estudiantes. Por ello, el objetivo de esta investigación es explorar los estilos predominantes a partir de las prácticas motivacionales que utilizan las maestras. El estudio de caso sigue un enfoque cualitativo, recogiendo información a través de la observación y la encuesta. Así, se encontraron prácticas motivacionales que corresponden a los estilos de estructura y de apoyo a la autonomía. De esta manera, se concluye que el estilo de apoyo a la autonomía está presente al buscar un alto grado de participación del estudiante; sin embargo, es el estilo de estructura el que predomina en estas aulas, caracterizado por la constante guía y orientación de las maestras. Para próximas investigaciones sería útil incluir un mayor número de docentes, lo cual permita extrapolar y generalizar conclusiones.
Platform Spiritualities: Entrepreneurial Selves and Post-Feminist Sensibilities of Russian Influencers
Authors: Balishyan Sabina , Kompatsiaris Panos
Published: January 2024

In this article, we look at how preeminent Russian-speaking influencers spread sensibilities of entrepreneurialism and post-feminism on social media platforms, and specifically Instagram. Drawing on platform studies, critical theory and material from influencer accounts, we explore the ways that platform-based spiritualities are embedded in the neoliberal economies of self-presentation, micro-celebrity and branding in Russia and beyond. We understand spirituality as a broader figure encompassing both external beliefs in the divine, such as in magic, spirits and forces that lie beyond human understanding, as well as internal beliefs in spiritual tropes for reaching self-development, including exercise, mindfulness and life coaching, among others. By amplifying presentations of the self around regimes of happiness, positivity, self-growth and unfettered joy, platform spiritualities nullify critical thought and normalize a depoliticized conception of selfhood in the Russian public space. Influencers encourage women to focus on themselves, travel, dress up, dream about wealthy husbands and exotic sensations, and prioritize their own well-being and empowerment over social or collective concerns. The depoliticized discourse of these influencers is largely an outcome of the social media imperative to produce safe and riskless content under the fear of cancellation, which can lead to a loss of advertising and other forms of revenue. We argue that, rather than being simply progressive vehicles for democratic publics and participatory cultures, social media platforms, and Instagram in particular, are key to intensifying an entrepreneurial selfhood that relies on magical thinking and spiritual guidance from abstract authorities in repressive political contexts.
EXPERIMENTAL AND THEORETICAL CHARACTERIZATION OF TWO-PHASE FLOW DISTRIBUTION IN UNBALANCED FLOW NETWORKS
Authors: Kim Cheol-Hwan , Giannetti Niccolo , Kim Nae-Hyun , Saito Kiyoshi
Published: January 2024

This study investigates the two-phase flow distribution of R-1234yf into two-branched channels. The effect of unbalanced pressure drop and tube diameter on the flow distribution was especially characterized and modeled. The experiments were conducted for a mass flux ranging from 393 kg/m2s to 1179 kg/ m2s, and the inlet quality was fixed at 0.2. The flow distribution was mainly governed by the pressure drop ratio between two branched channels. The mal-distribution under the unbalanced pressure drop condition was mitigated by increasing mass flux, whereas sustained mal-distribution was observed under unbalanced tube diameter conditions. Correspondingly, a theoretical representation of the phenomenon based on the principle of minimum entropy production was developed and adopted to predict two-phase flow distribution in an unbalanced flow network. The characteristics of the experimental data were clearly and quantitatively reflected in the prediction results. Under the unbalanced pressure drop condition, the predictions agreed well with the experimental data, maintaining the maximum deviation within ± 30%, whereas it exceeded ± 30% under the unbalanced tube diameter condition. The analysis of such theoretical formulation suggests the necessity of appropriate pressure drop models of flow impact, contraction, and merging at the outlet channel, which are compatible with the extremization of entropy production for further improving the prediction accuracy without compromising its generality.
THE DIFFERENT OF COMPLEX VERBS FROM ANOTHER, SIMILAR LINGUISTIC PHENOMENA IN THE KYRGYZ LANGUAGE
Authors:   Institute of Language and Literature named after Chingiz Aitmatov of the National Academy of Sciences of the Kyrgyz Republic, Bayastanova Aigul
Published: January 2024

It is known that complex verbs in the Kyrgyz language are formed by combining adverbial forms in -ып, -а, -й, -gany with a subsequent verb or an auxiliary pair. However, free verb combinations built from two or more paired components can also be formed in the same exact form. Although the outwardly named verbal structures are similar, they differ sharply from each other in their internal structure, semantic and syntactic function. This work is devoted to such actively used complex verbs of the Kyrgyz language, which are so similar in structure to other linguistic phenomena that drawing a line between them in some cases causes considerable difficulties, and which have not yet become the subject of scientific research outside the framework of the general grammar of the Kyrgyz language. Determining the boundaries of similar verbs requires comparative consideration. The fact is that complex constructions of grammatical type in the Kyrgyz language are special isolated constructions and there are semantic and formal characteristics that accurately and clearly distinguish such constructions.
CREOLIZED TEXT OR TEXTUAL HETEROGENEITY AT THE LEVEL OF THE RATIO OF VERBAL AND NON-VERBAL COMPONENTS OF THE TEXT
Authors:   Kyrgyz State University named after I.Arabaev, Jenishova Suusara
Published: January 2024

Creolized texts, which are semantically complex texts of a higher order, have become the most relevant objects of linguistic research. Creolized text, hybrid text, supertext; bimedial, polymedial, multimedia text; multimodal, verbal-visual text; multicode, polycode text; semantically enriched text and communicat - all these terms emphasize that text as a communicative quantity is not limited only to the linguistic component. The composition of the text consists of many different elements that inherently affect our perception of the text as a whole. All these aspects of creolized texts prove the relevance of the article from the point of view of not only linguistics, but also the theory of communication. So, the problem brought up for consideration in this article is the problem of textual heterogeneity, traceable at the level of form, manifested in the ratio of verbal and nonverbal components of the text.

Authors:   Bishkek State University named after K.Karasaev, Isakova Saltanat
Published: January 2024

This article systematizes and describes the genre of interpretation of political discourse, the ways in which journalists manipulate readers, through interpretative tactics. The relevance of the topic is that contemporary political discourse is permeated by aggression, hostility and cynicism. Politics and the media are linked and interdependent, as the media can support or, conversely, undermine political structures that already exist in society. For our analysis, we considered speeches Kyrgyz politicians as a genre of political discourse at the Jogorku Kenesh meetings and identified how a speech event is interpreted in media discourse, or more specifically, what genre characteristics are attributed to the speech event. According to the data of objective reproduction of the speech event, we identify the following genres of interpretation of political speech: accusations, threats, warnings, promises, which are determined by the target content of the statement as a factor of regulation of speech communication.
THE ROLE OF FIGURES OF SPEECH IN CONTEMPORARY COLLOQUIAL FRENCH
Authors:   Azerbaijan University of Languages, Nasirov Ahir
Published: January 2024

This article mainly deals with the figures of speech, which are nowadays widely used in French spoken language. The article points out that the figures of speech, found mainly in examples from literary materials, are often used during dialogues to give speech specificity and to make ordinary colloquial speech more expressive. During a discourse, it is unavoidable to use descriptive means to convey emotions and feelings to the other party. In order to develop this factor in detail, this article explains some examples of the use of metaphor, metonymy, hyperbole, comparison, personification and other figures of speech from a number of novels by the 21st century French writer Faïza Guène. From the article we can see that figurative language is in most cases necessary for humans to express themselves clearly. However, it concludes that much research will be needed in the future to analyze the unique place of each figure of speech in modern colloquial French. Because, as the French linguist Ruth Amossy says, the importance of reflection on figures cannot fail to raise fruitful questions about the complex relationship between style and argumentation. Indeed, one may ask to what extent style contributes to the impact of speech.

Published: January 2024

This paper discusses the features of the formation of students' ideas about health, a healthy lifestyle in biology lessons in the 8th grade. A healthy lifestyle is defined as "a set of knowledge, practical skills, value orientations of schoolchildren, corresponding to their age, manifested in specific types of activity and life activities aimed at maintaining and strengthening their own health and the health of other people." In biology classes, students' attention is focused on priority risk factors and lifestyle conditions that affect both their health and general well-being, as well as their current and future learning abilities. Therefore, the most important part of teaching biology is the motivation of students to preserve and strengthen their health, that is, the formation of a healthy lifestyle and a conscious attitude to life and health.

Authors: Maldonado-Guzmán Gonzalo , Molina-Morejón Víctor Manuel , Juárez del Toro Raymundo
Published: January 2024

In the literature, evidence has been provided that establishes that compliance with environmental regulations promotes the adoption and implementation of eco-innovation activities in manufacturing firms, since through this type of activities not only are the costs associated with the discharges of pollutants, but also increases the level of sustainable performance of companies. However, little is known about the relationship between environmental regulations, eco-innovation, and sustainable performance, since there are few studies published in the literature that have focused on their analysis, so this study aims to fill this existing gap, and generate new knowledge of the relationship between these three constructs through an extensive review of the literature. Likewise, a questionnaire was distributed to a sample of 460 manufacturing firms in Mexico, analyzing the data through confirmatory factor analysis and structural equation models based on covariance. The results obtained suggest that environmental regulations have positive effects on eco-innovation, and eco-innovation has positive effects on sustainable performance of manufacturing firms in the automotive industry. In this context, the results obtained allowed us to conclude that compliance with environmental regulations established by the public administration, by manufacturing firms in the automotive industry, improve both eco-innovation activities and sustainable performance of organizations.

Published: January 2024

Objectives: This study addresses the concept drift issue in anomaly detection for IoT systems. The objective is to develop a novel approach that effectively handles the dynamic nature of IoT data. Methods: The proposed COMCADSET (Combination of One-Class and Multi-Class Anomaly Detection Using Under-Sampling and Ensemble Technique) addresses the concept drift challenge. It adapts to evolving data distributions, detects anomalies in IoT healthcare data, mitigates class distribution imbalances through under-sampling, and enhances performance with ensemble techniques. The approach involves four phases: multi-class anomaly spotting, one-class anomaly isolation, concept-drift-free dataset creation, and robust anomaly detection using ensembles. Evaluation utilizes the "Heart Failure Prediction" dataset from Kaggle, with comprehensive experiments and three classification algorithms. COMCADSET's innovation merges one-class and multi-class anomaly detection, under-sampling, and ensemble classification. It's compared against gold standards for classification accuracy, concept drift management, and anomaly detection performance. Findings: Conduct comprehensive experiments using a concept drift dataset and three classification algorithms to evaluate the efficacy of the COMCADSET technique. The experimental result shows the proposed COMCADSET technique attains an impressive 98.401% accuracy, decisively enhancing classification accuracy by adeptly addressing concept drift and identifying anomalies in IoT data. Early detection of abnormal behaviour prevents more significant issues and potential security vulnerabilities in IoT systems. Novelty: The novelty of the COMCADSET technique lies in its ability to address the concept drift issue and improve anomaly detection accuracy in IoT systems. By integrating one-class and multi-class anomaly detection, under-sampling, and ensemble techniques, the proposed approach provides a robust solution for handling the dynamic nature of IoT data.

Authors:   Department of Computer Science, Punjabi University, Patiala, Punjab, India, Singh Shamandeep , Singh Simranjit , Kaur Bikrampal
Published: January 2024

Background: Optical transport has emerged as a candidate solution to cope with the rising data transmission challenges of enormously evolving data. In Optical Burst Switching (OBS) networks, determining an adaptive burst size is a difficult task that must be performed efficiently during burst assembling. Methods: This research proposes a hybrid burst assembly algorithm that determines the optimal burst size during the burst creation time. The proposed algorithm uses the Transition Count Number (TCN) based method to maintain the optimal burst size when the incoming traffic is unpredictable. The efficiency of the proposed approach is investigated in terms of queuing delay, burst utilization, burst size, and burst size consistency. Findings: Three types of traffic variations (H = 0.5, H = 0.6, and H = 0.7) are imposed to evaluate the performance of the proposed burst assembly approach. As compared to the E-hybrid (time/length) strategy, the research outcomes demonstrate a 13.15% reduction in average queuing latency and a 21.26% improvement in average burst utilization. Novelty: A new burst assembly approach (hybrid burst assembly) has been proposed for OBS networks. Keywords: Burst assembly, Optical Burst Switching (OBS), burstification, burst consistency

method for estimating the position and direction of a leader of a set of moving objects
Authors: Moreno Arboleda Francisco Javier , Duitama Muñoz John Freddy , Ospina Edison Camilo
Published: January 2024

Movement patterns can be identified when studying a group of moving entities such as a group of people, a flock of birds, a school of fish, a convoy of vehicles, among others. In this paper, it is analyzed a pattern, known as leadership. Informally, this pattern is characterized by a moving entity called leader that motivates or represents the behavior of the group in order to reach a goal during a period. A formal method is proposed to estimate the position and the direction where a leader should be located and headed at a time-point in order to lead a group. These estimations can also be useful to check the consistency of the data about a leadership pattern, and to estimate the missing information (position and direction) of a leader at a specific time, i.e., an imputation process. In order to show the expediency of the proposal, a series of experiments were implemented and conducted using Netlogo, a programmable modeling environment for simulating natural and social phenomena.

Published: January 2024

The biotransformation of trans-cinnamic acid by whole cells of the Colombian native phytopathogenic fungus Colletotrichum acutatum was studied. Initially, fungitoxicity of this compound against C. acutatum was evaluated; trans-cinnamic acid exhibited a moderate to weak toxicity against the microorganism and apparently a detoxification mechanism was present. Then, in order to study such mechanism and explore the capacity of this fungus to biotransform trans-cinnamic acid into value-added products, the microorganism was incubated with the substrate using three different culture media (Czapeck-Dox, Sabouraud and PDB) at room conditions. Using Czapeck-Dox medium, whole cultures of C. acutatum reduced trans-cinnamic acid, first to aldehydes (trans-cinnamaldehyde and 3-phenylpropanal), then to alcohols (cinnamyl alcohol and 3-phenyl-1-propanol). Subsequently, these alcohols were transformed to the corresponding acetyl esters. Nevertheless, some of these products were absent or present at different concentration when culture medium was changed. The results suggest a mechanism of detoxification in which the α,β-unsaturated carbonyl system is affected. Besides, the formed metabolic products are useful compounds used as fragrances and flavors. Therefore, metabolism of trans-cinnamic acid using C. acutatum can provide new potential metabolic targets to control C. acutatum as well as a simple and efficient way to obtain flavor compounds and perfumes, such as cinnamyl alcohol and 3-phenyl-1-propanol, and their acetyl esters.
A cheating prevention EVC scheme using watermarking techniques
Authors: Espejel Trujillo Angelina , Nakano Miyatake Mariko , Iwamoto Mitsugu , Perez Meana Hector
Published: January 2024

Visual Cryptography (VC), proposed by Naor and Shamir in 1994, is a variation of the conventional secret sharing scheme. In VC, instead of a numerical secret key, a secret image is shared among participants in the form of images called shares. Each participant possesses his own share which cannot reveal the secret image being alone, making it necessary to stack more than one share of a qualified participant in order to reveal the secret image. Thus in VC the stacking of shares is equivalent to the decryption process, where neither extra computations nor previous knowledge are required to reveal the secret image. Until now some important VC schemes, such as the (k,n)-VC scheme, the general access structure for VC and the extended VC (EVC), have been proposed. Unfortunately all schemes can be cheated, if one or more participants try to generate their fake shares to force the revealed secret image to be a faked one. In this paper, we propose a cheating prevention VC scheme, in which the shares can be identified and authenticated using the EVC scheme and watermarking techniques. In the proposed VC scheme, the share of each participant can be identified by its meaningful appearance instead of noise-like image used in the conventional VC scheme. For the purpose of authentication of each share two binary watermark images are encrypted using shift operation. Before the secret image is revealed, the validation of the shares must be carried out, extracting two watermark images. If they can be extracted correctly, the revealed secret image is considered as authentic; otherwise it is determined as a faked one. The simulation results show the desirable performance of the proposed EVC scheme.
Improvement of micro-hardness and electrochemical properties of Al-4%Cu-0.5%Mg alloy by Ag addition
Authors: Correa Reinaldo , Sánchez Héctor , Calderón Jorge A.
Published: January 2024

The base system of alloys Al-4% Cu-0. 5% Mg, known as the designation of duralumin 201, are very appreciated by the aerospace, partly automotive and industrial in general, for its great strength, high temperature and corrosion resistant. These kinds of alloys have excellent response to precipitation hardening. This study evaluates the effect of silver content in the microstructure, mechanical properties and corrosion resistance of the alloy. It was found that the addition of silver in the alloys led to a delay time of homogenization and accelerates the aging time, causing the precipitation of Guinier Preston zones and the consequent increase in hardness and improvement of the mechanical properties of alloys. Moreover, the addition of Ag to alloys Al-4% Cu-0.5% Mg gives a better resistance to corrosion, giving noble features and reducing the corrosion current in chloride aqueous media. The global control of the dissolution of the alloys Al-4% Cu-0.5% Mg-Ag will be given by the diffusion of oxygen from the bulk of the solution to the metal surface. The corrosion potential of alloys Al-4% Cu-0.5% Mg-Ag coincide with the pitting potential of the material (-0.62V), this makes the material not generate a passive layer and its dissolution is controlled purely by activation of the surface and the reaction rate of the cathodic reduction of oxygen.

Mathematical formulation of restrictions for the design of low voltage bandgap references
Authors: Polanco Alicia , Nagy Agnes , Álvarez Manuel
Published: January 2024

Nowadays the qualities more looked for in the design of bandgap references are the low potential of the reference and the low value of its coefficient of temperature, being these parameters more favorable in curvature corrected bandgap references. The design parameters of bandgap references depend on the value of the potential of reference VREF ; nevertheless, in the reported designs there are not paid attention to conditions that limit the attainable value of VREF. In this work the mathematical formulation of the restrictions that really limit the attainable value of the reference potential is presented in order that the design of a curvature corrected bandgap reference can be realizable.
Development of an algorithm to generate and evaluate cutting solutions in edging and trimming operations at sawmills
Authors: Vergara González Francisco , Baesle Abufarde Felipe , Ramos Maldonado Mario
Published: January 2024

In this research work an algorithm that gathers the best procedures applied in sawmills was developed, along with a methodology based on cutting geometrical line analysis. This application was programmed under the C++language, sizes objective board and its prices, and the 2-D slab geometry are the input data, obtaining length and width solutions for every slab. Its outcomes have been compared with a pattern that matches the solutions provided by an “optimized” cutting machine in a southern sawmill in Chile. Four types of solutions were obtained when inputting slabs geometry, which was captured with four different reading steps. Outcomes show that solutions achieved with a reading width of 100 mm were 4% better in average than the pattern, and far better to other solutions achieved with the remaining 3 steps.
Leaving aside the particular operating conditions of either method; a theoretical comparison of time by solution method, indicates that the 77 milliseconds SISCORMAD employed are significantly lower than those obtained with dynamic programming 320 milliseconds, 890 milliseconds with total enumeration, and 140 milliseconds obtained with geometric heuristic as solution times reported by [6 ]. This feature makes the developed algorithm very attractive for future applications. However, given the heuristic nature SISCORMAD, it is just a high quality solution, but not optimal.
New factor for voltage sags characterization
Authors: García Quintero Edwin , Villada Duque Fernando , Cadavid Carmona Diego
Published: January 2024

A new factor which allows characterizing voltage sags in an individual way is presented in this paper. The factor acts revises and identifies voltage sags in a univocal way. In order to verify such characterization, the proposed factor is applied and compared with other reported factors, such as: not supplied energy (referred to in IEEE P1564 Norm) which is widely used for obtaining some important indexes for a series of real registrations measured on the electric network and to others obtained by simulations. The effect of voltage sags on the behavior of some sensitive elements is also analyzed. The idea is to contrast results and overcome some lacks presented by the most used characterization factors nowadays. The new proposed factor will be useful for obtaining indexes, among many other applications.
Vendor Managed Inventory (VMI) in micro, small and medium enterprises (MSMEs) – Plantain agricultural-chain
Authors: Arango Serna Martín Darío , Adarme Jaime Wilson , Contreras Portilla Patricia
Published: January 2024

This paper emerges as a research result of the Vendor Managed Inventory (VMI) issue to a dehydrated plantain productive chain, which is composed by a dehydrating plant (supplier) and a pig-raise farm (client), adding the product transport cost as an integral parameter to inventory cost, in order to examine the inventory process practice before and after establishing VMI. Initially a chain contextualization in the field sector and the Colombian plantain agro-industry is shown. Then, the inventory coordination model is formulated taking as reference the model proposed by Yao, et al. [1], which is based on the model of economic batch supplier order. According to the previous information, the mathematical model is then applied with VMI and without VMI, after that, the product transport cost is incorporated to the total cost of management inventory. The result shows that VMI adoption generates savings for the integrated chain and how the transport cost becomes a relevant individual element in the structure for logistics cost of the analyzed chain.

Just Transition for China’s Coal Regions Towards Carbon Neutrality Targets
Authors: Zhang Ying , Miao Dan , Hou Xiangding , Jia Mingjie
Published: January 2024

China has pledged to peak its carbon emissions before 2030 and achieve carbon neutrality by 2060. A crucial aspect of this commitment involves transitioning from coal‐dependent activities primarily concentrated in certain regions pivotal to local economies, employment, and livelihoods. High‐quality development necessitates identifying just transition strategies for these coal‐intensive regions, ensuring inclusive benefits from the energy transition. These regions exhibit disparities in economic and industrial growth, with many low‐income mining communities and inadequate public services. This calls for comprehensive policy interventions in economic, energy, societal, and environmental domains. This study aims to delineate just transition strategies for China’s coal regions, considering their unique challenges and circumstances. Initially, this article reviews the evolution of “just transition” as a concept and its policy implications. Subsequently, it explores China’s approach to achieving carbon neutrality through the lens of just transition, delving into the local economy’s reliance on coal‐related industries and the impact on employment. Following a clear delineation of the vision for just transition in China, the analysis focuses on identifying principles and pathways for transition. The goal is to propose nuanced and effective policies to ensure just outcomes in the context of China’s energy transition.
Hidden Dimensions of Injustice in the Green Transition of China’s Coal Mining Industry
Authors: Zhang Guanli , Zhang Bingyi
Published: January 2024

The social impact of China’s policy of phasing out excess coal production since the 2010s is examined through the lens of “just transition.” Qualitative fieldwork undertaken in Liupanshui, Guizhou province, focussed on seven mines, among which three were decommissioned. Against the backdrop of top‐down policy imperatives aimed at rapidly reducing coal production capacity, more powerful stakeholders took action to safeguard their own perceived interests, thereby transferring the costs of transition to the least powerful actors while exacerbating existing injustices. At the same time, Confucian traditions and modern civic education in China—which prioritise endurance and compliance—limited individual voice and agency. By adopting just transition as a policy tool, China could avoid errors made by countries that transitioned earlier.
Relationship between Medication Adherence and the Glycemic Control in Type 2 Diabetic Patients in Sulaimaniyah City, Kurdistan Region, Iraq
Authors: Khdir Derin , Mohammed Mohammed
Published: January 2024

Background: Type 2 diabetes mellitus (T2DM) implies the highest incidence of diabetic cases. T2DM is related to metabolic ailments in the pancreas, kidneys, liver, and intestines.

 

Objective: To determine the impact of adherence to antidiabetic medication (ADMs) on glycemic control in T2DM patients.

 

Methods: This quasi-experimental study enrolled 245 participants (119 intervention patients and 126 non-intervention patients) with T2DM in the Diabetes and Endocrine Center, Sulaimaniyah, Iraq, from January to August 2021. ADMs used the Morisky Medication Adherence Scale Item 8 (MMAS-8). Also, fasting blood glucose (FBG) and glycosylated hemoglobin (HbA1c %) were checked to assess glycemic control among the participants.

 

Results: The counseling program potentially improved ADMs as the rate of medium adherence increased significantly from 5.0% to 31.9% (p<0.001), with a significant improvement in glycemic control in the intervention group from 13.9% (before the intervention) to 21.8% (after the intervention) (p=0.039). However, there was no significant difference between ADMs and glycemic control (p>0.999).

 

Conclusion: Patients’ education and medication counseling significantly improved ADMs and glycemic control in people with T2DM.

Published: January 2024

Genetic algorithm (GA) is global numerical optimization approach is based on the genetic recombination and assessment in nature. This kind of optimization can be utilized to optimize the amplitude, phase levels and spacing distribution for the elements of an antenna array to achieve its best performance. In this study the genetic algorithm of the 4NEC2X software has been used to optimize the element spacing ( of both a uniform and non-uniform (Binomial and Chebyshev) current excitation for 10-element, 2.4 GHz linear broadside dipole antenna arrays. As a consequence, for the above-mentioned array antennas the spacing optimization yielded a notable improve in their directivity and Gain (dBi), such that for the uniform current excitation the gain was reached to 14.8dBi and for both Binomial and Chebyshev non-uniform current excitation the gain increased to 12.57 dBi and 15.04 dBi respectively.

A ring is Locally Noetherian if is Noetherian for each prime ideals of. In this paper we study Locally Noetherian rings. We show that Krull’s Principal Ideal Theorem and Generalized Principal Ideal Theorem are also true for Locally Noetherian rings. In general, Locally Noetherian rings do not have finitely many minimal prime ideals, a sufficient condition is given under which they have finitely many minimal prime ideals.
Impact of inclined magnetic field on non-orthogonal stagnation point flow of CNT-water through stretching surface in a porous medium
Authors: EL GLILI Issa , DRIOUICH Mohamed
Published: January 2024

The magnetohydrodynamic (MHD) nanofluid flow at non-orthogonal stagnation point, with suspended carbon nanotubes in water on a stretched sheet in a permeable media with non-lin-ear thermal radiation is studied. This work aims to explore the inclined magnetic field impacts on normal velocity, tangential velocity and temperature for both types of carbon nanotubes (CNTs). The governing flow equations which are continuity equation, momentum equation and energy equation are reformed into ordinary differential form with the proper boundary conditions using appropriate transformations. The computational solution of the nonlinear ODEs is obtained using the Bvp4c method. The graphs are presented to show the influence of certain physical factors which ranged as magnetic parameter (0.5 ≤ M ≤ 2.5), inclination angle of the magnetic field (п/2 ≤ ζ ≤ п/4), permeability parameter (0 ≤ Ω ≤ 2), volume fraction of nanoparticle (0.03 ≤ Φ ≤ 0.07), stretching ration parameter (0.3 ≤ γ2 ≤ 0.7), Radiation param-eter (0.5 ≤ Nr ≤ 0.9), the heating parameter (0.5 ≤ θw ≤ 1.5) and Prandtl number (5 ≤ Pr ≤ 10). The normal and tangential velocity drops with the augmentation of (M), (ζ) and (Ω), while the temperature rise with enhance of (Nr) and (θw). This study’s findings may be used to manage the heat transmission and fluid velocity rate to achieve the required final product quality in numerous manufacturing processes such as electronic cooling, solar heating, biomedical and nuclear system cooling. Validation against previous research available in the literature in spe-cific situations shows excellent agreement.
