Authors: Ferrández-García Cristina C. , Ferrández-García Clara E. , Ferrández-Villena Manuel , Ferrández-García M. Teresa , García-Ortuño Teresa
Published: March 2023

Acoustic and thermal properties were determined for boards made from Washingtonia palm tree pruning waste. Three types of boards with different particle sizes (0.25 to 1.00 mm, 1.00 to 2.00 mm, and 2.00 to 4.00 mm) were obtained from the rachis of the palm fronds. To bind the particles, 8% urea formaldehyde resin was used via hot pressing at 120 ºC for 6 min at 1.6 MPa. Three types of panels were generated to evaluate the influence of particle size. Analysis of their physico-mechanical properties showed that their mechanical performance was superior to the existing insulating boards used in the building industry. The average thermal conductivity of the panels was 0.062 W/(K·m) and did not depend on the size of the particles. At frequencies of 125 and 250 Hz, the experimental boards were classified as class D acoustic panels. The manufactured panels had high values of sound transmission loss (TL), despite the thinness of the panels, which indicates that they have good acoustic insulation capacity. Acoustic properties could be improved by increasing the thickness of the boards. Due to their mechanical, thermal, and acoustic properties, these panels could be used as lining and as false ceilings.

Authors: Zhang Jia Chan , Wang Chang Tao , Wang Cheng Tao , Wang Shou Xian , Sun Bao Guo
Published: March 2023

The feasibility of solid-state fermentation was studied for sea buckthorn seed residues (SBSR). Effects of different fermentation parameters were evaluated regarding the levels of biomass and compounds in aqueous and non-aqueous extracts. In the latent and logarithmic phases of fermentation, the total phenols and flavonoids were increased. The microbes’ decomposition on fibrous matter allowed the active components to be fully extracted. The changes of total sugar levels had a contrary trend with the changes of total phenol and flavonoid contents. The monosaccharide and polypeptide contents decreased dramatically and then kept steady along with the fermentation. Unsuitable environments led to weak growth of the fungi, limited enzyme contents, low enzyme activity, and a poor degradation of the substrates. The active compounds considered in the study were protected, and the contents reached a maximum under conditions that were usually not suitable for the fungal growth. The chemical structure was another important factor influencing the content and stability of the compounds. The content of procyanidins decreased dramatically because of its sensitivity to heat and alkaline environments. Antioxidant abilities of SBSR extracts, both aqueous and non-aqueous, increased after fermentation. These results reflected a possibility to recycle SBSR for further use in the food industry.

Published: March 2023

Wood chips screening rejects (WCSR) are mainly composed of sawdust, bark specks, and wood pins generated from cutting and chipping processes, as well as solid waste from pulping processes. It can be modified so that it can better serve as effective sorbents for wastewater treatment. In this study, three WCSR based sorbents were prepared by nitric acid, phosphoric acid, and sodium hydroxide treatment, respectively. The purpose of the three treatments on WCSR was to increase the specific area of WCSR, which is very essential to a high sorbent performance. It was found that nitric acid, phosphoric acid, and sodium hydroxide can be efficient modifiers of WCSR according to the results from SEM and specific area analyses, compared with those of the controls. The FT-IR results also supported the findings stated above. Thermogravimetric (TGA) analysis and X-ray diffraction (XRD) analyses were also applied to characterize the prepared sorbents. WCSR sorbents modified by the three treatments exhibited higher methylene blue adsorption values compared with that of the control sample, and that the WCSR-HNO3 sorbent achieved the highest MB adsorption value among others, thanks to the strong acidic properties and high reactivity of HNO3 with WCSR. The study paves a potential way to convert WCSR into effective sorbents by acid and alkali treatment.

Authors: Topak Fatıma , Akalin Mehmet Kuddusi
Published: March 2023

The pyrolysis of medlar seeds was performed at 350, 450, 550, and 650 °C with and without K2CO3, MgO, and expanded perlite (10 wt%). The maximum dichloromethane extract yield (6.70 wt%) was obtained at 450 °C in the pyrolysis experiments without catalyst, while the maximum bio-oil yield (50.3 wt%) was obtained at 650 °C in the presence of perlite. The dichloromethane extract and bio-oil yields decreased noticeably with the use of MgO and K2CO3. The bio-oils obtained from the non-catalytic runs mainly consisted of phenolic compounds. The use of catalysts had a noticeable effect on the composition and higher heating values of the bio-oils. The use of K2CO3 increased the relative content of 2-methoxyphenol at all tested temperatures and the relative content of 2,6-dimethoxyphenol and 2,6-dimethoxy-4-methylphenol increased with the use of expanded perlite at above 550 °C, while the use of MgO led to an increase in the relative content of 2,6-dimethoxy-4-methylphenol at above 550 °C. The bio-oil with the maximum higher heating value (30.4 MJ/kg) was obtained at 450 °C with the use of perlite. This study showed that medlar seeds are a good alternative source of waste biomass in the production of bio-oil that can be used as a biofuel.

Published: March 2023

Los estudios sobre sanciones ambientales en el mundo son muy escasos. Colombia no es la excepción. Para entender por qué en unos territorios se pueden presentar más sanciones ambientales que en otros, es necesario realizar estudios que determinen el promedio de expedientes sancionatorios y su asociación con determinadas características sociales y económicas. En esta investigación determinamos el promedio municipal de expedientes sancionatorios ambientales del departamento de Nariño y su relación con factores sociales y económicos, mediante un diseño ecológico. De manera complementaria, caracterizamos las sanciones ambientales según tipo de infractor, de infracción y de sanción. Nuestros resultados indican que el número de expedientes sancionatorios se incrementa proporcionalmente al ingreso total per cápita y el número de empresas generadoras de empleo formal por cada diez mil habitantes. Así mismo, se observó que la deforestación aumenta de acuerdo con las hectáreas de cultivos ilícitos y conlleva una reducción de la densidad poblacional. Este resultado es consistente con el hallazgo del tipo de infracción más frecuente entre las personas naturales que es el aprovechamiento forestal ilícito. No obstante, entre las personas jurídicas, la mayoría de las sanciones se deben a infracciones relacionadas con vertimientos de residuos y sustancias peligrosas.
Biocultural innovation in the Colombian Pacific Coast: Limits and potentialities for autonomous well-being
Authors: Reina-Rozo Juan David
Published: March 2023

Biocultural approaches have consolidated as a hybrid study area and advocacy from academia and social movements. Within this conceptual framework, biocultural innovation emerges as new ways of doing things based on diverse knowledge production (including the traditional), created landscapes, cultural and spiritual values, and customary norms. These processes translate into new knowledge, resources, capacities, and practices applied in the relationship with a territory. This paper aims to explore the possibilities of Biocultural Innovation (BI) in communities living in rural coastal environments, particularly on the Colombian Pacific Coast. To this end, we propose four community opportunities related to the biocultural paradigm: (a) community biocultural protocols; (b) nature seen as the subject of rights; (c) communal innovation practices created by grassroots communities; and (d) collective repositories of local knowledge. In conclusion, BI is an emerging research topic by communities and academia as a process to safeguard and foster their knowledge and culture intrinsically related to biodiversity toward autonomous well-being.

Authors: Marín-García Edward J. , Chaverra-Lasso Alexandra , Torres-Marín José-Neftalí
Published: March 2023

This research tested the impact on the soil when implementing a Clean Intensive Livestock Production System (CILPS) via Voisin Rational Grazing (VRG). The methodology consists of the characterization of soil-grass-cattle management, including the soil chemical and biological analysis in the case study farm and reference land (comparison between extensive and CILPS-VRG systems). In addition, the VRG impact on agroecological management was evaluated by calculating the Soil Organic Matter Indicator (SOMI). Once the samples were processed, the T-Student test was applied, verifying the homogeneity of variances (F-Fischer) for the chemical variables and the Kruskal-Wallis test for the biological variables. The results identified substantial differences in some edaphic parameters such as organic matter, percentage of organic carbon, nitrogen, sulfur, and calcium. Moreover, to diversify nematodes and differences in the Rhabdhitids sp., the process characterized products from the natural organic fertilization in the soil with VRG. Finally, the calculation of the SOMI with a value of 41.6 for VRG indicates soil with no alteration or natural balance.

La década para la restauración de ecosistemas (2021-2030) tiene el propósito a nivel mundial de incrementar a gran escala la restauración de ecosistemas degradados y destruidos. En este contexto, identificar y gestionar las amenazas y riesgos de origen natural y antrópico que pueden afectar los procesos de restauración ecológica es fundamental para cumplir los objetivos y metas establecidos. Como estudio de caso, se analizó el proceso de restauración de bosque seco tropical de 11 079 ha de la Central Hidroeléctrica El Quimbo, ubicada en el departamento de Huila, Colombia. El estudio tuvo un enfoque mixto: por un lado, se hizo revisión documental de amenazas de origen natural y antrópico en procesos de restauración y áreas de conservación; y, por otro lado, se realizaron dos encuestas a 62 actores relacionados con el proceso de restauración. Los datos obtenidos se analizaron mediante una matriz de vulnerabilidad basada en criterios físicos, bióticos, de conocimiento del proceso y del área. Finalmente, se estimaron los riesgos. Como resultados se identificaron 29 amenazas naturales y 46 antrópicas que pueden afectar los procesos de restauración en general; y, para el caso de estudio, se determinaron 15 amenazas naturales y 24 antrópicas. Los principales riesgos naturales identificados fueron: incendios forestales, sequía extrema y cambio climático. Los riesgos antrópicos más destacados fueron: ganadería no sostenible, invasión antrópica y aquellos relacionados con extracción y uso de recursos. A partir de los resultados, se formularon recomendaciones para avanzar en la gestión integral del riesgo. Se debe considerar un enfoque socioecológico para hacer una gestión integral de las posibles amenazas y riesgos en procesos de restauración.

Published: March 2023

Los aceites lubricantes usados son catalogados como residuos peligrosos por el contenido de metales pesados y sustancias tóxicas provenientes de la combustión y desgaste del motor, lo que representa un riesgo para las personas que los manipulan y generan contaminación ambiental. A pesar de perder su vida útil, los lubricantes usados pueden integrarse a la cadena productiva como materia prima secundaria, sin embargo, su utilidad se limita a la generación de energía térmica. Con el propósito de evaluar un tratamiento alternativo para el aceite lubricante usado, se caracterizó el lubricante y se encontraron componentes críticos de agua, calcio, fósforo, zinc y silicio. El tratamiento consistió en la hidrólisis con ácido sulfúrico a diferentes concentraciones (5 %, 10 % y 15 %, v/v) y posterior adsorción con ilmenita y carbón activado. Los resultados mostraron reducciones en los contenidos de silicio, aluminio, cromo, cobre, hierro, plomo, níquel, estaño, vanadio y bario, que cumplen con la norma técnica colombiana. Sin embargo, las concentraciones de calcio, magnesio, fósforo y zinc no cumplieron los niveles estipulados en la norma NTC 5996. Es necesario profundizar en la combinación de tratamientos para lograr criterios técnicos en el uso de aceites tratados.

The study sought to determine the level of effectiveness of security officers in conducting policies and regulations within Tagbilaran City malls. This was conducted in the six (6) Malls of Tagbilaran City, namely; Island City Mall, Alturas Mall, BQ Mall, Marcela Mall, Alta Citta Mall, and Galleria Louisa Mall. This study used a quantitative design with the use of a survey method in gathering data. The participants were the one hundred twenty (120) customers of the malls. Self-made questionnaires were constructed by the researchers with the help of the thesis adviser. Pilot testing was done and subjected to Cronbach’s Alpha Testing for reliability and consistency. The data gathered were then tabulated, analyzed, and interpreted. It was concluded that every security officer from the different malls within the City of Tagbilaran is duly responsible for imposing policies and regulations therein. Security officers always ensure the safety of every customer in their jurisdiction. It is recommended that the best way to improve the perception of the customers towards them is through the customer service they provide, not just to direct clients or customers but to the general community they encounter. The presence of security officers on sites provides a feeling of security and comfort to the customers and guests so having them in any area is important for the reputation of a business or company. Training will also make a real improvement in how security officers perform, thus, their agencies must provide seminars and training to improve their skills and abilities. Agencies must hire security officers with clean backgrounds and good reputations. Security officers must always be alert and have an eye for security and safety.

The main thrust of this study was to determine the level of stress in relation to the academic performance of Tagbilaran City College. The study utilized quantitative research. The level of stress of the respondents was determined using a modified standardized questionnaire adopted from Cohen & Mermeistein (1983). Percentages, Weighted Mean, Kruskal-Wallis Test, Chi-Square Test, ANOVA, Spearman Rank Correlation, and Pearson Product-Moment Correlation Coefficient were used to analyze the data collected. Results showed that the majority of the students were in the age range of 20 – 24 and female. Most of them took the BS Office Administration program, were full-time students and the majority of the respondents were second-year-level. It was revealed that students’ academic performance was interpreted as Very Good in terms of General Education and major subjects. There was an insignificant relationship between Age, Sex, and Course to Level of Stress, but year level was significant to the level of stress. Also, there was an insignificant relationship between Age, Sex, and year level to their Academic Performance, but the course was significant to academic performance. There was no significant relationship between the Level of Stress and academic performance and the study found a significant relationship between the ratings of the General Education subjects and major subjects. Thus, the ratings of the General Education subject can be associated with the major subjects. There is no significant variance between the Level of Stress and the course taken by the students. In addition, there was no significant correlation between the level of stress and sex, which means male and female students have the same level of stress. Moreover, a significant difference between the level of stress and the year level of the students. Second-year students overpowered the First-year students in relation to their level of stress.

Teaching is a profession with the highest requirements for emotional labor or the regulation of emotions. Facial expressions, poise, and bearing have an impact on their interaction with the students. Classroom management is a prerequisite to teaching. This study investigates the relationship between college professors' emotional labor and classroom management practices at the University of Bohol (UB) in Tagbilaran City, Bohol. The researcher utilized a quantitative descriptive survey method using the Teachers Emotional Labor Scale developed by Cukur (2009) and Classroom Management Practices of Washburn (2010). The respondents were regular college professors from the 11 tertiary colleges of the UB. The results revealed that college professors had high emotional labor for they are moderately able to manage their emotions during classes and highly practiced their classroom management. Furthermore, results showed an insignificant degree of relationship between the profile of the professors and their emotional labor. Likewise, there was no relationship between the profile and the classroom management practices of the respondents. Results further revealed that the teachers' emotional labor is not correlated with their classroom management practices.

Published: March 2023

The use of technology in education has modified teaching and learning processes. New concepts such as science, technology, engineering and mathematics (STEM) are changing traditional learning. The purpose of STEM education is to prepare students for university engineering courses and higher technical education. The main aim of the study reported on here was to understand the influence of a STEM-based teaching process in different socio-educational dimensions. This was done by comparing the results achieved with a traditional expository teaching process with different groups of students. A quasi-experimental design was applied. A sample of 231 Spanish students from the first year of secondary education (ESO) was chosen. The results show that the STEM approach was significant in all the dimensions of study and, according to teachers, was more influential for student motivation and grades. The results also show that the STEM teaching approach was significant in all the dimensions of study. These dimensions are motivation; teacher-student, student-content and student-student interactions; autonomy; collaboration; depth of content; resolution of problems; class time, student ratings; and teacher ratings. According to teachers, the strongest influence was on the students’ motivation and qualifications.

Published: March 2023

Abstract Pancreatic ductal adenocarcinoma is one of the most aggressive malignant neoplasms, with a one-year survival rate below 20%. Axial methods (computed tomography and magnetic resonance imaging) play a fundamental role in the diagnosis and staging of the disease, because they provide adequate anatomical resolution in the assessment of key structures, mainly vascular structures. Pancreatic ductal adenocarcinoma is most often discovered in advanced stages, when surgical resection is no longer feasible. In that scenario, minimally invasive treatment alternatives have been developed in attempts to change the natural history of the disease. Irreversible electroporation, an interventional procedure that minimizes deleterious effects on adjacent tissues, has proven useful for the treatment of tumors traditionally considered unresectable. Despite the growing acknowledgment of this technique as a tool for the management of pancreatic ductal adenocarcinoma, it is still relatively unknown among radiologists. In this study, we sought to provide an overview of the main characteristics and eligibility criteria that must be considered for the indication of irreversible electroporation in cases of pancreatic ductal adenocarcinoma.

Published: March 2023

ABSTRACT: This article presents the research results on retextualization as a resource that favors students’ writing in the 6th year of elementary school. This practice makes it possible for students to have prior contact with texts to be produced by them and provides an opportunity for their understanding of the context of producing and receiving these texts. Students retextualized the short film La Luna into comic books in this study. The proposal consisted of changing the textual genre and maintaining the narrative typology, since, in the research, we focused specifically on the apprehension of the composition of the narrative textual type by the informants within the scope of their textual productions. For this, we adopted the theoretical socio-interactive approach based on Bronckart (1999), Antunes (2010), Marcuschi (2008), and Ribeiro (2013). The results of this study show that most students were able to structure their narrative text coherently and demonstrated that they learned how to build the narrative scheme.

ABSTRACT: Enterococci have been used as sentinel organisms for monitoring antimicrobial resistance in food, humans, and other animals. In this sense, the present study evaluated the antimicrobial susceptibility profile and the presence of genes associated with resistance to erythromycin (msrC and ermB) and tetracycline [tet(M) and/or tet(L)] in enterococci isolated from raw sheep’s milk and cheeses (colonial, feta-, and pecorino-type) from South region of Brazil. A total of 156 enterococci were isolated from milk (n=80) and cheese (n=76) samples, identified by MALDI-TOF. Enterococcus faecalis (50.6%; n=79) was the most frequent species isolated from both samples. According to in vitro susceptibility tests, enterococci strains were not susceptible to the most commonly antimicrobial agents used in human and veterinary medicine. The frequency of MDR strains in enterococci isolated from milk (53.7%) was higher than those from cheese (24.2%). The tet(M) gene was the most commonly detected among tetracycline not-susceptible strains. The present study provided the first evidence of antimicrobial not-susceptible enterococci in raw sheep’s milk and cheeses in South Brazil. Drug-resistant strains, particularly those that are MDR, constitute a One Health issue.
Matabilidade como forma de governo: violências, desigualdades e Estado numa perspectiva comparativa entre Florianópolis e Rio de Janeiro
Authors: Medeiros Flavia
Published: March 2023

Resumo O artigo aborda processos de produção de mortos que acionam novas (in)sensibilidades e modos de expressão sobre o morrer e a morte, alcançando de forma dilatada grupos já ostensivamente expostos ao risco da morte e à naturalização de suas mortes. A partir de dados etnográficos produzidos em pesquisa realizada nas regiões metropolitanas de Florianópolis e do Rio de Janeiro, observa-se como essa dinâmica se atualiza no contexto da pandemia de Covid-19 por uma promoção da expansão de formas de matabilidade que dilataram as instâncias de necropoder no âmbito de uma governamentalidade neoliberal. A análise irá refletir como a matabilidade se inscreve como dispositivo que circunscreve uma economia política e moral para modos de vida específicos, por meio da construção de mortos, a gestão do luto e a naturalização da morte.

RESUMO Objetivo: Este estudo visou avaliar a necessidade de ajuda dos idosos para tomar seus medicamentos, bem como as dificuldades relacionadas com a sua utilização, e a frequência de esquecimento de doses. Ainda, avaliar fatores associados à necessidade de ajuda dos idosos com os medicamentos. Métodos: Corte transversal em uma coorte de idosos (60 anos ou mais — estudo “COMO VAI?”), em que foi avaliada a necessidade de ajuda para tomar medicamentos de forma adequada e as dificuldades apresentadas na sua utilização. Utilizou-se regressão de Poisson para estimar as razões de prevalência (RP) brutas e ajustadas dos desfechos e seus intervalos de confiança de 95% (IC95%) de acordo com as características da amostra. Resultados: Participaram 1.161 idosos. A prevalência de idosos que relataram necessidade de ajuda com os medicamentos foi de 15,5% (IC95% 13,5–17,8), sendo que os mais idosos, com menor escolaridade e em pior situação econômica, em uso de quatro medicamentos ou mais e com pior autoavaliação de saúde foram os que mais necessitaram de ajuda. O uso contínuo de medicamentos foi referido por 83,0% (IC95% 80,7–85,1) e a maioria (74,9%; IC95% 72,0–77,5) nunca se esqueceu de tomar seus medicamentos. Conclusão: Observou-se a influência de determinantes sociais e econômicos e de saúde sobre a necessidade de ajuda para a utilização dos medicamentos. Estudos que estimem as dificuldades no uso de medicamentos por idosos são importantes para subsidiar políticas e práticas norteadoras de ações para melhorar a adesão e o uso racional de medicamentos.

Abstract The cardinal tetra Paracheirodon axelrodi is a species of the family Characidae of great interest as an ornamental fish. Many aspects of the biology of this species are still unknown. The present work presents a complete description of the different components of the digestive tract of P. axelrodi, analyzing its global anatomical arrangement, the adjacent glands (liver and pancreas) and the previously ignored pyloric caeca, using histological and histochemical techniques with light microscopy and scanning electron microscopy. Three levels of analysis were performed: macroscopic anatomy, histology of the gastrointestinal tract and scanning electron microscopy of mucosal surfaces. The intestinal coefficient (Ci) of P. axelrodi calculated here (0.94) is within the expected range for a carnivorous species. The anatomy of the alimentary and the resulting Ci is consistent with carnivorous diet in line with dietary studies in the wild in this species. The digestive tract, including adjacent glands (liver and pancreas), presented a relatively conserved general pattern within that described for other species of the family Characidae, especially at the histological level.

ABSTRACT While tomatoes can be grown year-round in a greenhouse, the high temperatures of tropical climates are a limitation. As such, cooling the growing environment is key to cultivating tomatoes in controlled environments during summer, but effective cooling systems are expensive and involve high production costs. The use of biostimulants has been reported to increase yield and can mitigate the effects of high temperature on greenhouse-grown tomatoes. Our hypothesis is that biostimulants can improve tomato yield, particularly in the event of stress during cultivation. Our aim was to assess the effects of three biostimulants on greenhouse-grown tomato plants in the summer under a tropical climate. The experiment was conducted in a greenhouse on the Uberaba Campus of the Federal Institute of the Mineiro Triangle (IFTM). We used a completely randomized design consisting of a plot containing five plants, with 1.0 x 0.5 m spacing, an estimated density of 20,000 plants ha-1, and six repetitions. The three biostimulants applied were Alquifishmel®, Booster® and Stimulate®, compared to a control (plants with no biostimulant). Production, fruit quality, yield and plant growth were assessed. All three biostimulants improved yield by more than three metric tons per hectare in relation to the control, primarily due to the larger number of ripe fruits. It is suggested that the biostimulants mitigated heat stress, promoting a larger number of fruits per truss and resulting in higher yield.
Stripping Time: erotic-political rifts in the performance project Strip Tempo - contemporary stripteases
Authors: Lordelo Lia da Rocha , Alencar Jorge
Published: March 2023

ABSTRACT This article instigates relations between an artistic creation and its composition with a political time by examining the artistic project Strip Tempo - contemporary stripteases (2018). The live version of the project premiered the same week Jair Bolsonaro was elected president of Brazil. Its online configuration, Web-Strips (2021), took place during the pandemic. The text begins with a political and aesthetic contextualization of these performances; then, contributions from psychoanalysis and burlesque arts, along with the notion of performative archive, dialogue with the artistic proposition of stripteases. The conclusion affirms that the stripteases - in their live and remote versions - aesthetically and erotically summarize the trajectories of these contemporary artists. They also mobilize discussions about the naked body - whether as the last frontier of an ultra-conservative morality in Brazil, or as an experience that expresses an erotic drive in the arts.
The Body and Space: real and imaginary - Musings on site-specific
Authors: Cavrell Holly Elizabeth
Published: March 2023

ABSTRACT This article discusses a personal history of performances in which the focus is the body and its various relationships to space. Emphasis is given to the experiences of Cia. Domínio Público, a contemporary experimental research group, studies in site-specific and mural culture in Philadelphia. The discussion will traverse themes dealing with public art, site-specific performance, and intervention in public urban spaces. As the article explores new strategies for potentializing performative work in nontraditional venues, space is considered a partner in the creative process.
O Debate Legislativo sobre Aborto e Diversidade Sexual e as Eleições de 2018: Uma Mirada Antropológica Sobre a Onda Conservadora
Authors: Luna Naara , Gomes Edlaine de Campos
Published: March 2023

Resumo O artigo aborda o debate sobre aborto e diversidade sexual em três instâncias do Poder Legislativo no ano das eleições de 2018: a Câmara dos Deputados, o Senado Federal e a Assembleia Legislativa do Estado do Rio de Janeiro. O objetivo é analisar quais referências aos temas do aborto e da diversidade sexual foram vinculadas a candidatos e partidos, entendendo que o resultado das eleições concretizou a onda conservadora. Em pesquisa qualitativa, usando metodologia de análise de discurso, são examinados pronunciamentos levantados nos mecanismos de busca das casas legislativas através de palavras-chaves. Também são analisados materiais de campanha produzidos por lideranças evangélicas. Aborto e diversidade sexual informam elementos acionados em disputas discursivas no campo político polarizado: conservadores e religiosos incluem aborto e “ideologia de gênero” em suas estratégias de acusação, enquanto a defesa da diversidade e de minorias e a denúncia de fake news são mote do lado progressista.
La evaluación del profesorado universitario: una mirada del estudiantado
Authors: Valentín-Martínez Bilda , Mayor-Ruiz Cristina
Published: March 2023

Resumen El presente artículo tiene como objetivo principal analizar la percepción que tienen los estudiantes del sistema de evaluación del profesorado en sus universidades. Aunque en la mayoría de las universidades en la República Dominicana la evaluación la realizan coordinadores, profesores y estudiantes, desde este estudio se indaga la situación a partir de los resultados analizados en las opiniones de 347 estudiantes de diferentes disciplinas de la carrera de Educación de siete instituciones de educación superior de este país. Para esto se aplica un cuestionario de preguntas abiertas y cerradas, que posibilita verificar el nivel de satisfacción que poseen estos actores del proceso de la evaluación del profesorado. La población participante se selecciona por medio de método no probabilístico, casual incidental, eligiendo directamente los participantes del quinto, sexto, séptimo, octavo y noveno cuatrimestres. Los resultados indican que los estudiantes consideran de gran valor el ser tomado en cuenta en el proceso de evaluación de sus profesores, que aprecian el nivel de confiabilidad de la aplicación del instrumento de evaluación; pero que la evaluación podría mejorarse tomando en cuenta otros componentes que no aparecen en ella e integrando preguntas abiertas, que les permitan expresar sus opiniones con mayor precisión. Los resultados son relevantes para el diseño de un nuevo sistema de evaluación del profesorado.

Published: March 2023

CO2 bubbly pipe flows with or without chemical absorption were measured to obtain spatial evolution of dissolving bubbly flows. The experiments were carried out using pure water and aqueous NaOH solution of pH = 13 at two gas volume fluxes. The spatial evolutions of flow patterns, mean void fractions, and bubble diameter distributions were obtained using an image processing method. The enhancement factor correlation proposed in our previous study was implemented into a three-dimensional one-way bubble tracking method to examine its applicability to CO2-water bubbly flow with chemical absorption. The numerical prediction agreed well with the measured spatial evolutions with or without chemical absorption, which confirmed the applicability of the enhancement factor correlation to bubbly pipe flows.
Undrained uplift resistance of under-reamed open caisson shafts

Published: March 2023

Deep, large-diameter caisson shafts are a popular means of constructing underground storage and attenuation tanks and pumping stations for the water and wastewater industry. One of the key design concerns for these structures is resistance to flotation during periods when the tanks are only partially filled or empty. In this paper, two-dimensional numerical analysis is used to explore the undrained uplift resistance provided by under-reaming the walls of the caisson shaft to create an enlarged base. The primary aim of the study is to assess the influence of the taper angle of the anchor (i.e. the protruded base) on the resulting uplift resistance. The effects of the anchor–soil interface roughness factor, soil weight, surcharge pressure and caisson radius are also investigated. The results indicate that the effect of the taper angle on both the uplift bearing capacity and the developed horizontal reaction can be very significant. The numerical output informs the development of a closed-form approach for application in routine design. The new design method is shown to provide an excellent agreement with both finite-element and additional finite-element limit analysis calculations. By way of example, the proposed design method is applied to a hypothetical design scenario.
