The partial substitution of maize by tropical legumes for the production of silage has aroused interest, for bringing benefits of increasing the crude protein content of corn-only silage, constituting an important alternative for the production of food in a more sustainable way. In this context, the objective of this study was to evaluate the effect of addition 30% tropical legumes on the fermentative characteristics and nutritive value of maize silage. The experimental design was entirely randomized with three replications. The treatments consisted of the following silages: Maize; Stylosanthes cv. Campo Grande, Stylosanthes cv. Bela: Pigeon pea (Cajanus cajan cv. BRS Mandarim), maize + 30% Campo Grande; maize + 30% Bela and maize + 30% Pigeon pea, totaling 21 experimental silos. The results show that exclusive legume silage without preservatives present fermentative losses that compromise the silage quality. Addition of 30% legumes to maize silage improves the nutritional quality of the silage without compromising its fermentation profile. Stylosanthes cv. Campo Grande and Bela are the most recommended locations for maize silage. Thus, a mixed silage of maize and legumes is an alternative to improve the crude protein content of exclusive maize exclusive silage, greater sustainability, and reduced fermentative losses of legume silages.

Published: December 2023

A relação entre fornecedores e consumidores carrega em sua essência aspectos complexos. Por um lado, fomenta-se a liberdade de oferta de produtos e serviços como um movimento natural em prol do desenvolvimento econômico; por outro, é necessário regular práticas comerciais e publicitárias com o objetivo de proteger os consumidores evitando abusos e danos. Nesse contexto, o presente estudo tem como objetivo responder à problemática: É possível haver uma proteção efetiva do consumidor em relação às más práticas comerciais, inclusive aquelas socialmente aceitas, subliminares e disfarçadas? Para alcançar resposta satisfatória ao problema, este estudo utiliza pesquisa exploratória, método analítico-dedutivo e técnica de pesquisa bibliográfica, fundada na literatura acadêmica, legislação vigente e em decisões judiciais proferidas pelo Superior Tribunal de Justiça do Brasil. Ao analisar as práticas comerciais corriqueiras - práticas comuns do ofertante - juridicamente denominadas "dolus bonus", conclui-se ser necessária a firma atuação do Poder Judiciário para que haja uma proteção efetiva do consumidor em relação às más práticas comerciais, em especial àquelas subliminares e disfarçadas eis que, não raro, fornecedores veiculam propagandas claramente ilegais valendo-se da tênue linha que distingue legalidade de ilegalidade para obter vantagens exageradas, desequilibrando assim as relações de consumo.

Authors: Moraes Cristina de
Published: December 2023

O presente trabalho tem como objetivo analisar quais os (possíveis) impactos da constituição do Acordo Aukus no Sistema Malvinas, Antártica e Atlântico Sul (SMAAS). Para tanto, o trabalho está dividido em duas partes. Na primeira, apresenta-se o Aukus (2021) e aborda-se a presença britânica no sistema mundial moderno. Em seguida, expõem-se as possíveis implicações do Aukus para o conjunto geográfico do SMAAS. Tem-se a hipótese de que, ao mesmo tempo em que o Aukus é uma estratégia de contenção de atuação chinesa no Indo-Pacífico, também demonstra um fortalecimento da atuação britânica na SMAAS, representando desdobramentos no conflito anglo-sul-americano. Para desenvolver este trabalho, foram empregadas a revisão bibliográfica de autores da área de geopolítica e a leitura de documentos oficiais.

Published: December 2023

Em diversas cidades do Brasil, o fenômeno da urbanização se desenvolveu mais intensamente a partir da segunda metade do século XX, provocando significativas alterações nas condições de uso da terra, resultando em consideráveis modificações no ciclo hidrológico. O reflexo dessas mudanças se tornou um dos principais problemas enfrentados pela sociedade, que é a potencialização da ocorrência de inundações. Dessa forma, o presente estudo buscou mapear as áreas suscetíveis a inundações na bacia hidrográfica do rio Duas Unas, em Pernambuco, utilizando o Sistema de Informações Geográficas (SIG) em conjunto com um dos métodos de auxílio de Tomada de Decisão por Múltiplos Critérios (MCDM), o Processo Analítico Hierárquico (AHP). Para isso, foram elencados sete fatores que contribuem para a ocorrência de inundações que foram processados no software QGIS (v. 3.10.9) pelas técnicas de reclassificação e álgebra de mapas. Assim, foi possível elaborar o mapeamento das áreas suscetíveis a inundações para a bacia estudada, sendo observado que as regiões mais propensas a esse tipo de desastre hidrológico são as que apresentam baixas altitudes e declividades, proximidades aos corpos hídricos, elevadas densidades de drenagem e áreas urbanizadas. Os resultados foram produzidos de modo satisfatório, demonstrando praticidade e eficiência quanto à precisão na sua determinação.

Published: December 2023

This empirical paper analyzed the relationship between project delivery methods on project performance within the Yemen construction industry (YCI). This research incorporated two distinct project delivery methods (PDM) namely the traditional Design-Bid-Build (DBB) and Design-Build (DB) and gauging project performance (PP) through the lens of the triple constraints (time, cost, and quality) as the criteria for measuring success. A conceptual model was theorized and operationalized in a survey of 375 project managers and consultants from two Yemeni governorates, Aden and Hadramout. The questionnaire employed a 5-point Likert Scale. Subsequently, the data were evaluated using multivariate regression. The empirical findings revealed a significant relationship between the choice of project delivery method and project performance. Thus, exerting a positive influence on project success. This study contributes to the existing body of knowledge in two significant ways. First, by scrutinizing the dynamic mechanisms through which project delivery methods impact project performance. Secondly, offers valuable insights for decision-makers in the Yemeni construction industry (YCI) to plan their objectives and achieve the requisite project performance levels.

Published: December 2023

Removal of phototoxicity and zootoxicity pollutants from the aqueous environment is of great importance to human and aquatic life. Copper-tunable p-type zinc oxide (Cu-ZnO) photocatalysts have been prepared by the chemical co-precipitation method. The structural, morphological, elemental and optical properties of the obtained catalysts were characterized using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray (EDX) analysis and ultraviolet-visible (UV-Vis) spectrophotometry. The diffraction patterns of the as-synthesized catalysts were matched with that of the hexagonal wurtzite structure for the standard ZnO nanoparticles. The photocatalytic activity of the prepared Cu-doped ZnO catalyst was evaluated using methylene blue (MB) dye under various conditions. The effect of operational parameters such as MB initial concentration, catalyst dosage, and solution pH was optimized using a face central composite design (FCCD) of the response surface methodology (RSM). The optimum photodegradation efficiency of 98.00% was found at 0.30g/L catalyst dose, 10.00mg/L initial concentration of MB and initial pH at 6.00. The degradation model was statistically remarkable with p < 0.0001% in which the MB initial concentration and solution pH were the most significant variables influencing the removal of MB over the Cu tunable p-type ZnO photocatalyst under visible light irradiation. Finally, the photocatalytic degradation of MB using the undoped and Cu-doped ZnO nanoparticles was nicely fitted pseudo-first-order kinetics scheme.

Did the Laodiceans Drink Lukewarm Water? A Hydrological Inquiry into the Temperature Metaphor of Revelation 3:15–16
Authors: WİLSON Mark
Published: December 2023

Laodicea is the last of the Seven Churches mentioned in the book of Revelation chapters 1–3. This article examines the interpretative issues related to the well-known temperature metaphor found in chapter 3:15–16. The mention of “hot, cold, and lukewarm” has been related to the city’s hydrological situation. First discussed are the early travelers to the site and what they wrote about its water system. In the twentieth century various interpretations arose that suggested its water source was inferior to others in the Lycus valley such as at Hierapolis and Colossae. The excavation of Laodicea beginning in 2003 has revealed much new information about the city’s hydrological situation. The proconsul’s edict about water found at the South Nymphaeum gives further insight into the city’s hydrology. Unfortunately, none of this is being reflected in contemporary discussions of the temperature metaphor in Revelation. After reviewing this new data, the article concludes that the interpretation that the temperature metaphor cannot be related to Laodicea’s hydrological situation.
Ottoman seals at the Hungarian National Museum
Authors: Gerelyes Ibolya
Published: December 2023

In her study, the author conveys the findings of chemical composition investigations performed on Ottoman seals in the collection of the Hungarian National Museum. The examinations conducted draw attention to connectedness between chemical composition, shape, and inscription type; this can assist with dating. In the material reviewed, one group stands out in particular: seals with bell-shaped bodies which can in all likelihood be dated to the 16th–17th centuries and which in most cases feature an inscription with the formula ‘Trusting in the King…’. At the same time, some pieces bearing just the name of their owner differ from the other examples in the collection in terms of shape and chemical composition. These were certainly made after the period of Ottoman sway in Hungary.

District-Level Support for Site-Based Renewal: A Case Study of Secondary School Reform
Authors: Ross John A. , Hannay Lynne , Brydges Bruce
Published: December 2023

Previous studies of secondary school reform have not given as much attention to the role of the district as is warranted by its potential influence on change processes. This study examined the role of district-level factors in enabling eight secondary schools to restructure their positions of added responsibility. After two years there was significant change on five of six indicators of organizational health. The district-level factors that contributed to the change were the actions of a central steering committee (consisting of administrators, union representatives, and support staff), an emerging image of professionalism in the teacher union, district history, individual personalities, and a shared sense that the district was unique in its region. The findings differed from the results of previous research in that leadership was more broadly distributed, a combined industrial-professional conception of teacher unionism contributed to innovation, and a strong and continuous central presence was required to support a decentralized change model.

Authors: Daniels Lia M. , Mandzuk David , Perry Raymond P. , Moore Ceri
Published: December 2023

In a novel approach to initial teacher education, we combined a program review perspective and a psychological perspective. First, we assessed the extent to which student teachers (n=137) felt that components of their BEd program prepared them for teaching and whether these components represented meaningful program dimensions. Through content analysis, exploratory factor analysis, and teacher candidates’ own words, five dimensions emerged: classroom dynamics; curriculum, instruction, and assessment; intrapersonal reflection; ethics of teaching; and professional learning community. Second, we tested how each of these dimensions predicted teaching anxiety, efficacy, and commitment. The results from regression analyses showed that ethics of teaching was the most influential dimension by decreasing anxiety and increasing efficacy and commitment. Results are discussed in terms of the effect of initial teacher education program dimensions on the psychosocial development of teacher candidates. Adoptant une approche novatrice à la formation initiale des enseignants, nous avons combiné une perspective visant l'examen des programmes avec une perspective psychologique. Nous avons d'abord évalué la mesure dans laquelle les stagiaires (n=137) estimaient que des composantes de leur programme d'études (B.Ed.) les avaient préparés pour l'enseignement et à quel point ces composantes représentaient des dimensions significatives de leurs programmes. Cinq dimensions ont découlé des analyses du contenu, des facteurs exploratoires et des propres paroles des stagiaires : la dynamique en salle de classe; le programme d’étude, l’enseignement et l’évaluation; la réflexion intrapersonnelle; l’éthique et l’enseignement; et les communautés professionnelles d’enseignement. Nous avons ensuite évalué dans quelle mesure chacune de ces dimensions constituait une variable explicative de l’anxiété, l’efficacité et l’engagement en enseignement. Les résultats sont présentés en fonction de l’effet des dimensions du programme de formation initiale des enseignants sur le développement psychosocial des stagiaires.

Authors: Kariuki Daniel , Mwenda Lilian , Wachira Anita
Published: December 2023

Purpose: The main purpose of this study was to assess the effect of entrepreneurial culture as a driver of innovation by 1-3 star rated hotels in Kenya.

Methodology: This study considered positivism philosophy, a quantitative measurement paradigm. The study targeted 111 hotels (1-3 star rated) through census, of which 3 respondents per hotel (CEO, Finance manager, and Operations manager) were considered, from the hotels’ list provided by the Kenya Tourism Regulatory Authority (TRA). A cross-sectional survey was conducted where the self-administered questionnaire was used. Both the reliability and validity tests were done before the data analysis. The collected data was analyzed using descriptive and inferential statistics with the help of Excel and SPSS version 25.0. The hypotheses were presented and tested using multiple analysis and accepted at 95 percent confidence level.

Results: The study hypothesized that the effect of entrepreneurial culture on innovation by 1-3 stars rated hotels in Kenya is not statistically significant. The study revealed that entrepreneurial culture has a positive and significant effect on hotel innovation by 1-3 star rated hotels in Kenya (β=0.567, p=0.000). This implies that improvement in 1 unit of the aspects related to entrepreneurial culture leads to an improvement in hotel innovation by 1-3 star rated hotels in Kenya by 0.567 units. This implies that an increase in entrepreneurial culture results in an increase in hotel innovation by 1-3 star rated hotels in Kenya. The study concludes that there is an entrepreneurial culture that can be concluded to enhance the innovation of the hotels. This has been noted where the hotel management always appreciates new business ideas from employees and other stakeholders. The management portrays the visionary leadership style that ensures the continuity of the business. In extension, the hotels that have excelled in innovation, encourage and support employees to continue pursuing new opportunities even when their previous ones had failed to pick up as expected; values communication as a tool for effective innovative strategies; appreciates the use of modern technology as a mechanism to offer reinforcement to innovation; employs risk management strategies in the course of innovation process and always embraces new changes that come with new ideas discovered and exploited.

Unique contribution to theory, policy and practice: The study recommends that hotel entrepreneurs be proactive in seeking new product ideas and customer product information which will in turn enable them to create ideas for coming up with innovative products. Studies have shown that there is a positive and significant impact of entrepreneurial culture on all the perceived performance measures, with the exception of perceived financial performance measures.

Published: December 2023

Background: College students cope with a variety of activities that demand organizational skills which may increase stress. Perceived control over time is the perception of having enough time to finish one’s work meet one’s deadlines. This influences time management behaviors, satisfaction, independent engagement in daily activities, academic success and stress. Aim: To evaluate the self-perception of daily functions and control over time among college students with and without Attention Deficits and/or Specific Learning Disorders, who were seeking support, correlated with their demographic characteristics. Method: Participants: Thirty-six students (3 males, 33 females), mean age 23.42 + 4.80, who approached the college's student support center. Instruments: Behavioral Rating Inventory of Executive Functions (BRIEF- A) and Time Organization and Participation Scale (TOPS). Results: Significant correlations were found between the BRIEF - A and the TOPS subscales. Comorbidity of SLD and ADHD was associated with a lower perceived performance as measured in those scales while the demographic variables did not. Conclusions: Occupational therapists may have an important role in students' support centers and are encouraged to evaluate perceived control over time, of students, facilitate time management skills, and guide a discovery of strategies for balancing between demanding academic and extra curriculums tasks.

Resisting EFL Textbooks in the English as a Foreign Language Education System
Authors: ULUM Ömer Gökhan
Published: December 2023

A society's language reflects its values, norms, and other characteristics and is considered an integral component of these traits. This would be an incomplete language education, despite the fact that it is possible to teach a language without addressing the cultural aspects of the society that speaks it. This study aims to highlight the predominance of inner circle cultural and societal traits in English language education. The evaluation of a global EFL textbook revealed that the majority of the content reflected inner circle cultural characteristics. The efficacy of this method of language instruction is a subject of debate among academics. Critics argue that this approach may perpetuate linguistic imperialism and hinder the development of intercultural communicative competence. However, proponents suggest that a standardised curriculum can provide learners with a solid foundation in the language and facilitate communication with speakers from different parts of the world.

Authors: Gamez Saint Pasteur Adriana , Medina Díaz Aída Carolina
Published: December 2023

La Hipomineralización Molar Incisivo (HMI) presenta una prevalencia entre 2,9% y 44%. El dolor y la hipersensibilidad dentaria son el principal motivo de consulta de los pacientes afectados, y es por ello que un diagnóstico oportuno y una intervención eficaz brinda mejoras notables en la calidad de vida del paciente. Presentación de caso: Se trata de paciente masculino de 8 años de edad quien acude al Servicio de Odontopediatría y Ortodoncia del Centro Médico Docente la Trinidad por presentar dolor e hipersensibilidad.  En la evaluación clínica y radiográfica se observa destrucción de gran parte de esmalte y dentina en los primeros molares permanentes superiores e inferiores, con restauraciones atípicas presentes, siendo el diagnóstico de HMI severa con pulpitis irreversible. También se diagnostica maloclusión Clase II División 1 con mordida profunda. Se realiza, bajo sedación endovenosa, extracción de los primeros molares permanentes, logrando la mesialización de los segundos molares permantes con el cierre de espacio completo y correcta inclinación, evidenciando una óptima evolución. Una vez emergidos los segundos molares permanentes, inicia tratamiento de Ortodoncia con mecánica Clase II. Conclusión: El caso paciente reportado presentó hipomineralización severa de los primeros molares permanentes, siendo tratado con extracciones de los molares permanentes afectados en el momento oportuno. En el seguimiento a 5 años se observó mesialización exitosa de los segundos molares permanentes.
Erupción forzada de incisivos centrales superiores permanentes retenidos como consecuencia de dientes supernumerarios. Reporte de caso.
Authors: Acosta Berroteran Ramses , Einem Müller Bernhard Von
Published: December 2023

Los dientes supernumerarios son alteraciones del desarrollo que se forman adicionalmente a la serie normal. Pueden ubicarse en el área de los maxilares de forma cónica, trabeculada o suplementaria teniendo la capacidad de ocasionar alteraciones de erupción en los dientes permanentes, desplazamiento y maloclusiones. En el caso de los dientes permanentes retenidos con formación radicular completa pierden capacidad eruptiva por lo que se ha descrito la necesidad de realizar tracción ortodóncica. Objetivo: Describir tratamiento y evolución de paciente pediátrico con retención de incisivos centrales permanentes por presencia de supernumerarios tuberculados. Presentación de caso: Paciente masculino, de 10 años de edad, referido por cirugía maxilofacial que acude a la consulta del Servicio de Odontopediatría y Ortodoncia del CMDLT por presentar ausencia clínica de los incisivos centrales permanentes superiores. Al examen clínico e imagenológico (Radiografía panorámica, Cefálica lateral y TC) se evidencia persistencia de incisivos centrales primarios, retención de 11 y 21, con formación radicular completa, presencia de 3 supernumerarios tuberculados. Se realizó la extracción dental sin novedad y posterior cementado de botón para tracción ortodóncica. Conclusiones: La erupción forzada mediante la técnica de tracción ortodóncica garantiza la posibilidad de poder incluir en el arco los dientes retenidos en el maxilar a través fuerzas controladas apoyadas en el uso de aparatología combinada que permita la consolidación de una oclusión correcta previniendo o interceptando precozmente problemas ortodóncicos, que se puedan convertir en grandes maloclusiones.

Authors: De Faria Jardim Raquel , De Oliveira José Carlos
Published: December 2023

Antecedentes: la etiología del bruxismo y del síndrome de apnea obstructiva del sueño, se ha considerado multifactorial. Por lo tanto, estos agentes tienen la capacidad de incidir y activar la respuesta muscular para que se desarrolle este hábito parafuncional (bruxismo). Este último, es un evento que surge como fase de protección a los eventos respiratorios y que ocurren poco tiempo después de la finalización de la apnea.  Propósito: el objetivo de este estudio es establecer la relación entre apnea obstructiva del sueño y el bruxismo en pacientes mayores de 18 años. Materiales y métodos: búsqueda electrónica en las bases de datos: Pubmed, Medigraphic y Google Academic. Resultados: Se seleccionaron 54 artículos para ser analizados, 8 artículos fueron descartados, ya que no establecían datos referentes a la relación entre bruxismo y apnea obstructiva del sueño, 4 fueron excluidos por ser duplicados. 21 estudios fueron evaluados, donde se descartaron 5 artículos, ya que sus resultados eran inconclusos. De los 16 artículos restantes, se escogieron 13, de los cuales se leyó el texto completo y fueron excluidos 3, ya que eran estudios basados en pacientes edéntulos e infantiles y no se consideran relevantes para este estudio. Por lo tanto, 10 artículos finales fueron incluidos para la discusión de esta revisión sistemática. Conclusiones: El bruxismo y la apnea obstructiva del sueño, están relacionados entre sí, siendo el Bruxismo un efecto secundario con el fin de proteger al organismo, generando una afección en la calidad de vida del individuo y en su desempeño habitual.

Translucencia nucal aumentada: capacidad predictiva para cromosomopatías.
Authors: Rubino Salaverria Andrea , González Arias Freddy
Published: December 2023

Introducción: La Translucencia Nucal (TN) es un marcador ecográfico para el diagnóstico de cromosomopatías en el primer trimestre de gestación. La TN aumentada se relaciona con cromosomopatías principalmente trisomías 21 en 50% . Asociado a un mal pronóstico perinatal y neonatal, aunque existe  un porcentaje de fetos normales a pesar de una TN aumentada Objetivo: Correlacionar los resultados de cariotipo  en muestras de líquido amniótico (LA)  de vellosidades coriales (VC) en los pacientes con TN aumentada durante el tamizaje ultrasonográfico.  Método: Estudio analítico, restrospectivo, cohorte tipo III. La población se confromó por 5.969 muestras de pacientes con estudio citogenénico entre el año 2011-2022, con indicación de TN aumentada, se obtuvieron  141  resultados   y  la muestra se conformó  por  52 LA donde se reportó el grosor de la TN  y 30 resultados  BVC que cumplieron con los criterios de inclusión. Resultados: Se reportó  cariotipo fetal en LA  normal  en  46,30% y  anormal en 57.70%.  En VC se reporto 60% normal y 40% anormal. La trisomía 21 fue la cromosomopatía más común en ambos tipos de estudios, seguida de Monosomía X, Trisomía 18 y Trisomía 13. La Monosomía X es la que presenta  la  TN  de mayor grosor en el grupo de  LA y  la Trisomia 21 en el grupo  de  VC. Conclusión: El aumento del grosor de la translucencia nucal fetal a las 11 a 14 semanas es una expresión fenotípica común de cromosomopatías y malformaciones, sin embargo se  puede presentar aumentada  en fetos euploides,  con desarrollo posnatal normal.

Published: December 2023

Objetivo: Establecer la relación entre diabetes mellitus tipo 2 y el desarrollo de cáncer de tiroides en los pacientes que acuden a la consulta de cirugía oncológica de cabeza y cuello del CMDLT en el período comprendido entre enero 2018- enero 2023. Métodos: Estudio de tipo observacional, analítico, con casos controles, transversal, el cual incluyó 24 pacientes, obteniendo diagnóstico histopatológico de carcinoma de tiroides y previamente antecedente de diabetes. Se evaluó el comportamiento epidemiológico y desarrollo del carcinoma en presencia de diabetes mellitus tipo 2. Resultado: Más de la mitad de los pacientes (61%) pertenecieron al grupo con ambos diagnósticos, estimando una alta probabilidad comprendida entre 26,6 y 50,8% que el diagnóstico de diabetes mellitus tipo 2 previo sea un factor de riesgo para desarrollar cáncer de tiroides, con un IC del 95%. Además, se asocia que el diagnóstico de diabetes establecido en un tiempo mayor a 5 años pueda será el responsable del desarrollo de carcinogénesis; constatándose además que la histología más frecuente fue de carcinoma diferenciado, específicamente carcinoma papilar de tiroides (79%). Conclusión: La presencia de diabetes mellitus como factor de riesgo está relacionada con el cáncer de tiroides en pacientes jóvenes, menores de 50 años, asociado a un tiempo mayor de 5 años del diagnóstico endocrino patológico.
