Authors: Ordoñez Elizabeth S. , Reátegui Diaz Darlym , Menacho-Mallqui Tomas
Published: May 2023

Aim: To evaluate the effect of germination on total phenols, antioxidant capacity, trace elements, and thermal behavior of the seeds of Pigeon peas (Cajanus cajan L.) and Chacha and Recline varieties of the common bean (Phaseolus vulgarisL.). Methodology: The evaluation of the total phenols was done using Folin Ciocalteu’s spectrophotometric method; the antioxidant capacity through the DPPH y ABTSº+ radicals;the macro and microelements using the spectrophotometric optical emission coupled inductively with plasma method ICP-OES; and the thermic behavior through differential scanning calorimetry (DSC). Results: The germination process influenced the total polyphenol content, antioxidant capacity, and macro and microelements in each specie that was studied. For example, for the Recline variety seedlings, the phenol content increased by 57.75% in comparison to the seed. The antioxidant capacity against DPPH and ABTS º+ was greater in the seedlings in the following order: Chaucha variety>Pigeon pea>Recline variety. For the seeds, the macro and micro-element content had the following order: K>Mg>Ca>Na y Fe>Zn>Cu>Cr; for the seedlings, the greatest decrease was in K, Cr and the greatest increase was in Ca and Mn; the Na:K relationship was less than one. Finally, the thermic behavior, in reference to the gelatinization enthalpy (ΔH) was greater for the seed than the seedlings.

Published: May 2023

Introducción: las infecciones respiratorias superiores constituyen la principal enfermedad de la infancia, los pacientes menores de 5 años reciben mayor prescripción antibiótica y, por ende, aumenta el riesgo de resistencia antimicrobiana. Objetivo: abordar la antibioticoterapia prescrita en pacientes pediátricos de una unidad de salud en Tungurahua-Ecuador. Metodología: se analizaron 91 historias clínicas de pacientes entre 1 a 6 años, que recibieron asistencia ambulatoria durante los meses de julio a octubre del 2019, y que en su prescripción según su diagnóstico, requirieron antibioticoterapia. Se determinaron enfermedades de mayor prevalencia y antibióticos más prescritos durante el estudio, comparando la correspondencia entre la prescripción emitida y la indicada en el protocolo terapéutico del Ministerio de Salud Pública de Ecuador. Resultados: las infecciones del tracto respiratorio superior alcanzaron un 83,52% de los diagnósticos encontrados y entre ellas la amigdalitis fue la más frecuente. Los macrólidos con un 50,55% fueron los fármacos más prescritos. Al estimar la correspondencia entre los prescitos durante el período de investigación y los indicados en el documento oficial, se encontró que la prescripción de los antibióticos de segunda elección con 38,46% superaron a los de primera elección que solo alcanzaron el 14,29% y estos a su vez, fueron superados por la prescripción de otros antibióticos con un 47,25%. Conclusiones: la antibioticoterapia empleada para las infecciones respiratorias pediátricas no se ajustó con los fármacos de primera y segunda elección, establecidos en el protocolo terapéutico oficial, así, es necesario revisar y actualizar dichos documentos, considerando las realidades epidemiológicas y la resistencia antimicrobiana.

Published: May 2023

Introduction:Byrsonima garcibarrigae is an endemic tree of Amazonas state, Brazil, with pharmacological and chemical knowledge poorly understood. Aim: To investigate the antidiabetic potential of the B. garcibarrigae stem bark. Methods: The stem bark was sequentially extracted by maceration with hexane (EHBG), ethyl acetate (EABG), and methanol (EMBG). The antioxidant capacity, α-glucosidase inhibitory potentials and anti-glycation capacities were evaluated. A bio-guided fractionation gave compounds that were characterized by MS and NMR. Results: 8 compounds were identified by HPLC-MS. EMBG showed the highest α-glucosidase inhibitory activity (1.09±0.32 μg/mL), antioxidant activity (9.2±0.23 μg/mL) and phenolic compounds content (61.43±0.50%), thus was fractionated producing hexane (FHX), chloroform (FCL) and hydromethanolic (FHM) fractions. After additional anti-α-glucosidase assays, FHM (1.02±0.49 μg/mL) was fractionated giving quercitrin and epicatechin. The anti-glycation assay showed that EMBG, FHM and quercitrin presented higher activities in comparison to the positive control, aminoguanidine. Conclusions:B. garcibarrigae displayed antidiabetic potential since inhibited α-glucosidase, as well as presented expressive antioxidant and anti-glycation activities were recorded.

Published: May 2023

This study aims to discuss the hadis about understanding the sutrah in prayer. This research is a qualitative method by literature study using the syarah hadis methods. The results and discussion of this study include the definition of the sutrah, the types of sutrah, the provisions of the sutrah, the editorials of the hadis in the sutrah, and feminist responses to the traditions of the sutrah and their explanations. The results of the study explaining the distance between people who pray and the sutrah, the size of the height of the sutra, the sutrah in Indonesia, how to prevent people passing in front of the mushalli, and cancel the prayer if there is no sutrah. The results also found that the sutrah or barrier in prayer does not have to be in accordance with what has been mentioned above. What is clear is that these objects can prevent someone from passing in front of people who are praying. The distance between the person who prays and his surah is that there is sufficient space for prostration. The forms of Sutrah or barriers that exist in Indonesia are shaf and prayer mats. The opinion regarding the prohibition of walking in front of people praying is still a difference of opinion among the schools of thought.

Authors: COSTA ANA CLARA FREITAS GALVÃO SOARES , FONSECA NETO OLIVAL CIRILO LUCENA DA
Published: May 2023

ABSTRACT The first cases of COVID-19 were diagnosed in China, rapidly evolving with worldwide spread, turning into a pandemic. A percentage of these patients develop the severe form of the disease and progress to respiratory distress syndrome, requiring support in Intensive Care Units. Intra-abdominal Hypertension and Abdominal Compartment Syndrome are characterized by increased intra-abdominal pressure, and are subject to several predisposing factors, such as mechanical ventilation assistance, extracorporeal membrane oxygenation, elevated PEEP, intestinal obstructions, excessive fluid replacement, major burns and coagulopathies. Hence, for the management of patients with severe COVID-19, there are numerous risk factors for the development of intra-abdominal hypertension and abdominal compartment syndrome. Therefore, this study proposes to analyze the variables that directly interfere with the increase in intra-abdominal pressure in patients with COVID-19, as well as the changes in the organic systems caused, through an integrative literature review.
THE REFORM OF PROFESSIONAL AND TECHNOLOGICAL EDUCATION IN BRAZIL: 2016 TO 2021
Authors: PELISSARI LUCAS BARBOSA
Published: May 2023

ABSTRACT: The objective of the article is to analyze the impacts of the current Brazilian educational counter-reform process on Professional and Technological Education (EPT). In this context, we start from the hypothesis that the counter-reform of High School has produced transformations in other fields of educational policy, including EPT, not restricted to the general education curriculum. The concept of counter-reform as elaborated by the political theory of Poulantzas is assumed as a theoretical presupposition. From a methodological way, initially, a group of legal-political mechanisms that relate simultaneously to High School and EPT were delimited. Then, through the Content Analysis technique, official documents that support such mechanisms were investigated, emphasizing the political-pedagogical and curricular principles. The mechanisms analyzed are: a) Common National Curriculum Base (BNCC) for High School, expressed in Resolution CNE/CEB No. 17/2018; b) New Paths Program (PNC), announced by the federal government in November 2019; c) National Curriculum Guidelines for EPT (DCNEPT), approved by Resolution CNE/CP No. 01/2021. In conclusion, we defend the thesis that a reform of the Brazilian EPT has been in development, since 2016, a reform of the Brazilian EPT. This reform has been constructed in three stages, chronologically comprised between the years 2016-2018, 2018-2021, and 2021 onwards. The emphasis given to the reform of the EPT is intended to characterize it as one of the sectors that make up the current context of neoliberal counter-reforms in Brazil, therefore, professional education is not exempt from deeper changes in the content of its policies.

Published: May 2023

RESUMO: O artigo tem como objetivo apresentar e discutir as concepções e práticas de leitura exploradas nos cadernos de formação do Pacto Nacional pela Alfabetização na Idade Certa (PNAIC). O processo de análise do conteúdo dos cadernos foi conduzido com base na seguinte questão: qual a concepção de leitura e quais práticas de ensino são trazidas pela coleção de cadernos do PNAIC? A discussão das concepções e práticas de leitura foi feita com base em estudos teóricos que a entendem como ato cognitivo que se estabelece na interação texto-leitor. Os resultados da análise mostram que os textos dos cadernos de formação concebem a leitura a partir de elementos do modelo interativo de leitura. Em relação às suas práticas, priorizam-se as atividades de extração de sentidos do texto para o desenvolvimento da compreensão textual. Nos relatos, preponderam registros de atividades de leitura compartilhada, em que a formulação de perguntas é a principal estratégia utilizada para auxiliar o estudante a localizar informações e inferir sentidos. Já os exercícios que visam ativar conhecimentos prévios do leitor ou atividades de sistematização da leitura, como escrita de resumo, têm uma menor frequência. Por fim, destaca-se a importância de analisar pressupostos teóricos e metodológicos de programas de formação continuada, para entender como estes auxiliam as professoras a refletirem sobre suas práticas e a repensá-las de acordo com as necessidades dos estudantes.
THE FISSURES BETWEEN BEING AND MUST BE: SELF-REFLECTIONS FROM A PHYSICAL EDUCATION TEACHER
Authors: ALBINO BEATRIZ STAIMBACH
Published: May 2023

ABSTRACT: Since the 1980s there has been a certain fascination with the theme of the reflective/researching teacher. Little is said, however, that this discussion is part of a larger one, which criticizes positivism and rationality. Following the tradition of Critical Social Theory, some theoretical and methodological assumptions were discussed in order to then reflect on the teaching practice and the school context in which this author is inserted. Violence and indifference as inherent to the civilizing process, of which education is part, and the confrontation of the contradictions between the teacher’s being and “must be” as an antidote to the reproduction of barbarism, appear as central themes. The use of records and memories of the period of initiation to teaching and insertion in the work environment (years 2019 and 2020) was made, with attention to my doing teaching and a latent “teacher must be” in daily school life, in its interconnections with social and cultural aspects. In the elaboration work (cognitive and affective) of the experience, the little rationality prevailing in the school space was one of the key points of the analysis, revealing itself, among others: the insistence on rhetoric and educational postulates, at the expense of denying reality; the predominance of the principle of competition, especially among peers and with singularities that relate to gender issues; and the difficulty of facing violence in physical education classes. It ends with some notes on teacher self-reflection, especially the urgency that the ethical-political principle overlaps merely instrumental/performative objectives in this process.
TEACHER EDUCATION AND TEACHING AS PHRONESIS: BEING AND LEARNING TO BE
Authors: KRONBAUER LUIZ GILBERTO , FENSTERSEIFER PAULO EVALDO
Published: May 2023

Abstract: Inspired by the Aristotelian notion of Phronesis, we developed a reflection on teacher formation, in the perspective of learning as an exercise continuously done and redone, grounded on a reflexive and theoretical attitude. We approximated the concept of the contemplative life to one of the reflexive teachers aiming to advance toward praxis as a dialectic process of action-reflection-action, the background to pre-service education of teachers, which intertwines theory and practice as the horizon of a “living teaching”. This re-reading of Aristotle’s practical philosophy is followed by Hans-Georg-Gadamer’s interpretation, in his work Wahrheit und Methode, using the concepts of practical wisdom and mimesis, the productivity of the concept of experience, and Aristotle’s hermeneutic topicality, which structure the following text.
THE MARTIN EGER RESEARCH PROGRAM: PRINCIPLES OF PHILOSOPHICAL HERMENEUTICS IN SCIENCE EDUCATION
Authors: GALIAZZI MARIA DO CARMO , SOUSA ROBSON SIMPLICIO DE
Published: May 2023

ABSTRACT: This text begins with a theoretical research program that seeks to map the tradition of Philosophical Hermeneutics (PH) in Science Education (SE), producing syntheses of works by different authors who assumed the PH in SE. The objective is to present research programs that articulated PH and SE as we tailored our own research program based on them. We started with the research on the work of Martin Eger, one of the pioneers in this discussion in English, who proposed a Philosophy of Science Education (PSE). The justification for this program is that PH provides arguments for understanding the role of language, which contributes to facing the daily challenges of teachers in Natural Sciences teaching and learning. In this text, based on a brief discussion of PH as developed by Hans-Georg Gadamer, we have studied Martin Eger's work. Some of the concepts proposed by Gadamer, such as the hermeneutic circle and the expansion and fusion of horizons, as well as the triple hermeneutics, proposed by Eger, have supported the understanding of the language of Natural Sciences, thus undoing the separation between subject and object; in this way, students, teachers in training, professors and researchers in Education and Science Education, as well as scientists, can be seen as interpreters of the Natural Sciences. By bringing together the work of Natural Sciences and the work of art in a cascade of interpretations throughout the production of scientific knowledge and its learning by students, Eger's academic production provides arguments to understand the very history of Science Teaching, by rescuing paths and reviews. At the same time, it brings inspiration to think about the present.

ABSTRACT Objective The objective of this study was to cross-culturally adapt the Perceived Nutrition Environment Measures Survey for use in the Brazilian context. Methods Independent translations into Portuguese of the original version and respective back-translations into English were performed. The steps were evaluated by an expert committee and the translated version was applied in a group of both genders, of different ages and education. Results After suggested modifications in the translation processes, the expert committee considered that the translated and adapted version presented conceptual and semantic equivalence. The translated version was applied to a sample of twenty people and only one question related to the amount of fat in the food required a new round to obtain understanding and clarity. Conclusion We present an adapted version of Perceived Nutrition Environment Measures Survey for the Brazilian context, which has adequate conceptual, cultural, and semantic equivalence, being objective and comparable to the original version. Future studies should confirm clarity, reliability, and validity.

Published: May 2023

ABSTRACT Objective To verify the factors associated with the perception of current silhouette and body image dissatisfaction in adults with obesity. Methods Cross-sectional study derived from the baseline of a randomized clinical trial. The perception of current silhouette and dissatisfaction with body image, defined by the difference between the perception of current and ideal silhouette, were obtained from a scale that ranged from one (smallest silhouette) to nine (largest silhouette). The independent variables investigated as associated factors (crude and adjusted linear regression) were: sex, age, skin color, body mass index (kg/m2), percentage of body fat, level of physical activity, and food intake. Results Sixty-nine obese individuals (body mass index ≥30kg/m2) were studied, 42 of whom were female and with the following mean values: 34.7 (±7.2) years; 33.5 (±2.8) kg/m2, and current silhouette of 6.6 (±0.9). All were dissatisfied with their excess body weight. The categories associated with a perception that matched the current silhouettes were male sex, white skin color, and higher body mass index values when compared to female sex, non-white, and lower body mass index values, respectively. Regarding body image dissatisfaction, white people had lower scores than those with other skin colors. Conclusion Being male, having white skin color, and having a higher body mass index were risk factors for the perception of larger body silhouettes, while only non-white skin color was associated with dissatisfaction with body image.
The effects of intuitive eating on body appreciation, body mass ındex, and nutritional behaviors in adults: a sample of Türkiye
Authors: Kayacan Aybike Gizem , Özçelik Ayşe Özfer
Published: May 2023

ABSTRACT Objective Intuitive eating is an adaptive eating style that makes a strong connection with internal physiological manifestations of hunger and satiety. This study was conducted to evaluate the effects of intuitive eating on body appreciation, body mass index, and nutritional behaviors in adults. Methods Sample consisted of 497 individuals. Data were collected online. The questionnaire form included a general information and physical activity evaluation form, anthropometric measurements, Intuitive Eating Scale-2, Body Appreciation Scale-2, and food frequency questionnaire. Results A statistically significant relationship was found between body mass index and eating for physical rather than emotional reasons, reliance on internal hunger and satiety cues, body-food choice congruence subscale scores, and total scale score. There was a correlation between body appreciation and unconditional permission to eat, reliance on internal hunger and satiety cues, body-food choice congruence subscale scores, and total scale score. The number of physically active intuitive eaters was significantly higher than non-intuitive eaters. A significant correlation was found between intuitive eating scores and frequency of consumption of fish, cake, biscuit, chocolate, granulated sugar, honey, jam, molasses, pastries and dairy-based desserts, sunflower oil, margarine, and sugary, carbonated drinks. Conclusion Intuitive eating can be an effective tool in sustaining and controlling weight loss, and with more studies, it may be possible to further spread this practice

Published: May 2023

ABSTRACT Objective To describe the prevalence of inadequate mineral intake and associated factors with calcium, iron, zinc, magnesium, phosphorus, and sodium intakes in individuals aged 15-24.9 years. Methods We analyzed 476 individuals from the Brazilian Study of Nutrition and Health, stratified into two age groups (adolescents aged 15-18.9 years and young adults aged 19-24.9 years). Mineral intake was obtained from two 24-hour Dietary Recalls. The values of the Estimated Average Requirement and the Tolerable Upper Intake Levels were considered to calculate the prevalence of inadequacy. Multiple logistic regression was used to determine associated factors with mineral intake. Results Calcium and magnesium had the highest prevalence of inadequacy (>83%) in both sexes and age groups. Sodium intake was above Tolerable Upper Intake Levels for the majority of the population studied (>68%). The intake of all minerals was different between the sexes for the two age groups (p<0.01), and it was not different between age groups (p>0.05). The associated factors with mineral intake were sex (calcium, iron, phosphorus, and sodium), age group (calcium, magnesium, phosphorus, and sodium), and physical activity (calcium, iron, and magnesium), followed by socioeconomic level (zinc and sodium) and body weight status (iron and sodium). Conclusion The expressive portion of the studied population is at nutritional risk for calcium, magnesium, and sodium. Such data can contribute to the national public policy revision that is related to micronutrient intake and the adoption of healthier habits by adolescents and young adults.

Resumen Ante la pandemia, el gobierno chileno implementó medidas de intervención que fueron eminentemente de carácter sanitario. Este proceso tuvo como sustento una serie de discursos de control y disciplinamiento social que apelaban al autocuidado, la prevención familiar y la auto-responsabilización. A través de la construcción de cuatro Narrativas de Vida de madres académicas, se presentan cuatro repertorios interpretativos críticos respecto de aquello: (a) una mirada cuestionadora a la reproducción de posturas neoconservadoras sobre cuidados y familia tradicional en pandemia; (b) cómo el énfasis discursivo en lo sanitario, invisibilizó otras problemáticas que cruzaron madres trabajadoras académicas y a la vez privilegió su vivencia cotidiana a través de la exposición sanitaria de otros cuerpos;(c) crítica a la contradicción de discursos en lo académico respecto a la flexibilización laboral frente a la pandemia y el exhorto a la mantención de estándares de productividad liberal y (d) una posibilidad de tejer resistencias colectivas.

RESUMO Objetivo: analisar o perfil de incidentes de segurança do paciente pediátrico em hospital universitário, com foco particular na comparação das notificações antes e durante a pandemia de COVID-19 e na percepção de profissionais de enfermagem. Método: estudo de método misto e estratégia convergente, realizado em hospital universitário, no sul do Brasil. Os dados foram coletados de um banco de dados de 1.663 notificações entre março e setembro de 2021. Após critérios de inclusão, totalizaram 418 registros de incidentes de segurança do paciente, ocorridos entre janeiro de 2019 a dezembro de 2020, que foram analisados por estatística descritiva com o SPSS 18.0; foram realizadas entrevistas semiestruturadas com 18 profissionais de enfermagem, sendo empregada a análise de conteúdo temática. Resultados: os incidentes de segurança ocorridos nas unidades pediátricas foram mais relacionados a medicações e fluídos intravenosos, sexo masculino e faixa etária dos lactentes. Não houve diferenças relevantes comparando as notificações de 2019 (219) com as de 2020 (199), havendo redução de apenas 20 (-9,13%) notificações. Na percepção dos profissionais, também não houve mudança expressiva nesse panorama. Conclusões: as características dos incidentes de segurança do paciente ocorridos em unidades pediátricas apresentaram poucas diferenças estatisticamente significativas nos períodos investigados, corroborando a percepção dos profissionais de enfermagem de que não houve mudança expressiva no panorama de incidentes da instituição. Estratégias de incentivo às notificações e aprimoramento desse sistema ainda são necessários para proporcionar um ambiente seguro ao paciente pediátrico.

Published: May 2023

Abstract The objective of this work was to evaluate the agronomic responses of 'BRS Vitória' grapevines under bio-fertigation with and without conventional soil fertilizer. A completely randomized design was used, with three treatments and 18 replicates. The treatments were: CFI, conventional soil fertilizer and irrigation; BF+CF, bio-fertigation and conventional fertilizer; and BF, only bio-fertigation. The following variables were evaluated: graft and rootstock diameters; plant growth; number of lateral buds; root, leaf, petiole, and gem starch contents; bunch number per plant, length, circumference, and fresh weight; berry number per bunch, length, diameter, fresh weight, soluble solid contents, titratable acidity, and pH; yield; and leaf macro- and micronutrient contents. From 100 to 150 days after transplanting (DAT), rootstock and graft diameters were similar, increasing from 250 to 300 DAT in the CFI treatment. The highest root starch content was 7.19% in BF at 150 DAT and 37.35% in BF+CF at 300 DAT. The plants in BF+CF showed the best results for bunch number per plant and fresh weight, resulting in a fruit yield 22% higher than that obtained in the other treatments. 'BRS-Vitória' grapevines show a satisfactory agronomic performance when bio-fertigated.

Published: May 2023

Abstract The objective of this work was to evaluate the effects of increasing rates of biochar produced with coffee straw, at two pyrolysis temperatures, on the chemical attributes of an Oxisol cultivated with conilon coffee (Coffea canephora) and on the nutrient content of coffee tree leaves. Treatments consisted of pyrolysis at two temperatures (350 and 600 °C) and of five biochar rates (0, 5, 10, 15, and 20 Mg ha-1). The following soil chemical attributes were evaluated: pH in water; P, K, Ca, Mg, Al, H+Al, Zn, Cu, Fe, and Mn contents; effective and potential cation exchange capacity (CEC); sum of bases (SB); base (V) and aluminium (m) saturation; and N, P, K, Ca, Mg, Zn, Cu, Fe, and Mn contents in the leaves. The biochar produced at 600°C, at rates of 10 and 15 Mg ha-1, promoted a greater K release into the soil. Regardless of temperature, coffee straw biochar increased K and P availability, sum of bases, base saturation, and CEC in the soil, but did not influence macro- and micronutrient contents in the leaves. The addition of increasing rates of coffee straw biochar in the soil increases P, K, Mg, SB, CEC, and V, regardless of pyrolysis temperature.

Published: May 2023

Abstract The objective of this work was to evaluate the effect of diets with cottonseed and vitamin E on the greenhouse gas (GHG) emissions of cattle feces analyzed in biodigesters. Animal feces were evaluated in 18 laboratory-scale anaerobic digesters through the following treatments: control, feces from cows fed with a control diet; CS, feces from cows fed with a cottonseed diet; and CSVitE, feces from cows fed with a cottonseed and vitamin E diet. The production of biogas and GHG was measured, and no differences were observed for the emissions of biogas, methane (CH4), and nitrous oxide (N2O). The partition of the gross energy of the anaerobic digestion process was similar among treatments. On average, 28% of gross energy fed was released as CH4, 47% during digestion, and 25% as other gases and heat. The addition of cottonseeds to the cattle diet increases the concentration of CH4 and reduces that of CO2, but it does not affect the total production of CH4, CO2, and N2O in the biodigesters. The inclusion of vitamin E in the diet has no effect on GHG production in the biodigesters.

Published: May 2023

As a newly discovered mechanism of cell death, disulfidptosis is expected to help diagnose and treat bladder cancer patients. First, data obtained from public databases were analyzed using bioinformatics techniques. SVA packages were used to combine data from different databases to remove batch effects. Then, the differential analysis and COX regression analysis of ten disulfidptosis-related genes identified four prognostically relevant differentially expressed genes which were subjected to Lasso regression for further screening to obtain model-related genes and output model formulas. The predictive power of the prognostic model was verified and the immunohistochemistry of model-related genes was verified in the HPA database. Pathway enrichment analysis was performed to identify the mechanism of bladder cancer development and progression. The tumor microenvironment and immune cell infiltration of bladder cancer patients with different risk scores were analyzed to personalize treatment. Then, information from the IMvigor210 database was used to predict the responsiveness of different risk patients to immunotherapy. The oncoPredict package was used to predict the sensitivity of patients at different risk to chemotherapy drugs, and its results have some reference value for guiding clinical use. After confirming that our model could reliably predict the prognosis of bladder cancer patients, the risk scores were combined with clinical information to create a nomogram to accurately calculate the patient survival rate. A prognostic model containing three disulfidptosis-related genes (NDUFA11, RPN1, SLC3A2) was constructed. The functional enrichment analysis and immune-related analysis indicated patients in the high-risk group were candidates for immunotherapy. The results of drug susceptibility analysis can guide more accurate treatment for bladder cancer patients and the nomogram can accurately predict patient survival. NDUFA11, RPN1, and SLC3A2 are potential novel biomarkers for the diagnosis and treatment of bladder cancer. The comprehensive analysis of tumor immune profiles indicated that patients in the high-risk group are expected to benefit from immunotherapy.

Assessment of the fire-induced spalling of high-strength concrete in concrete structures requires knowledge of the tensile strength of concrete at an elevated temperature. However, previous research has mainly focused on determining residual tensile strength, measured at the post-fire stage after cooling the specimens to ambient temperature. However, such residual tensile strength is only applicable to concrete after fire exposure and not during the fire event, which is usually more critical. In this study, the early residual splitting tensile strength of concrete at high temperature is determined experimentally. The test results indicate that early residual splitting tensile strength decreases with temperature. To understand this phenomenon, temperature distribution is examined. Compared to residual tensile strength, loss of early residual splitting tensile strength is found to be faster due to the elevated temperature effect. Lastly, in order to reproduce early residual splitting tensile strength, a numerical model is developed and empirical expressions are proposed for engineering application.

An extensive investigation was carried out to gain better understanding of the seismic-resilient features of Kath-Kuni structures (mainly timber-laced dry masonry construction) prevalent in the Himachal Pradesh region of India. The research involved field reconnaissance surveys through rapid visual screening to understand the structural configuration. Laboratory testing was then conducted to evaluate the mechanical properties, joint characteristics and interfacial resistance of timber and stones. The results from the field survey indicted that the symmetrical geometry, the use of lintels above openings and corner interlocking were the major contributors to the seismic resilience of the buildings. Laboratory tests on the timber joints present in the walls – namely dowel connections and double-dovetail joints – revealed the importance of connection conditions in increasing the shearing capacity. The shearing capacity was also found to be dependent on the overburden pressure, with the smallest capacity of the connections in the top portion of the wall and the highest capacity at the bottom portion of the wall. The interface of timber and stones contributed to a further increase in the shearing capacity of the walls. This research provides the first insights into the mechanical behaviour of joints of Kath-Kuni structures.

Beth sydd eisoes yn hysbys? Mae’r erthygl hon yn cynnig methodoleg ar gyfer ymchwilio i ddeallusrwydd emosiynol o fewn cyd-destunau gwaith arweinwyr addysgol. Roedd methodolegau sy’n bodoli eisoes yn cynnwys nifer o ddulliau a oedd weithiau’n gwrth-ddweud ei gilydd, heb yr un ohonynt yn gweddu’n union i nodau’r prosiect. Mae’r erthygl hon yn archwilio’r gwahanol enghreifftiau o wrth-ddweud sy’n codi ynddynt, ac yn cyfiawnhau’r dewis terfynol o dri dull ar gyfer sicrhau’r data angenrheidiol. Beth mae’r erthygl hon yn ei ychwanegu? Nid yw’r dulliau eu hunain yn newydd; yr hyn a oedd yn arloesol oedd eu defnydd cyfunol i ddehongli sut roedd arweinwyr yn credu eu bod yn defnyddio deallusrwydd emosiynol i ddylanwadu ar waith tîm a rhannu gweledigaeth. Mae materion cyfieithu sy’n deillio o gyd-destun yr ymchwil hefyd yn cael sylw byr. Mae’r cyfan wedi’i fframio trwy lens ymchwil fel taith, a methodoleg yn fap ar gyfer y daith honno. Beth yw’r goblygiadau? Mae’r erthygl hon wedi’i bwriadu ar gyfer arweinwyr ysgol, athrawon-ymchwilwyr ac academyddion sy’n dymuno archwilio effaith deallusrwydd emosiynol arweinwyr yn hytrach na dim ond ceisio ei fesur. Mae’n pwysleisio pwysigrwydd gwerthuso deallusrwydd emosiynol yn ei gyd-destun trwy ddisgrifio un prosiect a geisiodd grynhoi dirnadaeth ddofn o’r cysylltiadau rhwng deallusrwydd emosiynol ac arweinyddiaeth ysgol mewn tair ysgol gynradd yng Nghyprus.

Objetivo: Diagnosticar los componentes del capital intelectual en el proceso de I+D y los mecanismos de transferencia de conocimiento en los grupos de investigación en Colombia para el mejoramiento de prácticas de gestión de conocimiento y gestión tecnológica. Método: Se implementó un enfoque cuantitativo, mediante una encuesta con 15 ítems para el constructo de capital intelectual y 10 items para el constructo transferencia de conocimiento científico-técnico, a 214 investigadores de grupos de investigación de Colombia. Resultados: Los principales hallazgos señalan tres tipos de capital humano y siete mecanismos de transferencia de conocimiento con muy alta prioridad según la coincidencia en las opiniones de los encuestados. Los grupos en categoría B y C tienen conocimiento moderado en los cinco capitales relacionales y en los cinco tipos de capital humano. Los grupos de investigación A1 y A, tienen bastante o mucho conocimiento en cuatro de los cinco capitales humanos. Los grupos A1, A y B, tienen bastante o mucho conocimiento en cuatro mecanismos de transferencia de conocimiento. Discusiones: Se evidencia la mayor importancia otorgada a los impulsores de los capitales humano y relacional en investigadores de la Universidad del País Vasco. Para el caso de los grupos de investigación en Colombia, la coincidencia es parcial, porque los grupos de investigación A1 y A, tienen bastante o mucho conocimiento en los siguientes capitales humanos: CH4, CH1, CH3 y CH2, pero los grupos A1, A y B tienen conocimiento moderado en los cinco tipos de capital relacional. Conclusiones: Existen dos brechas generalizadas en todos los grupos debido a que tienen un conocimiento moderado en los cinco tipos de capital relacional y estructural. Los grupos de investigación mejor clasificados por Minciencias (A1 y A,) tienen bastante o mucho conocimiento en los capitales humanos: CH4, CH1, CH3 y CH2 (en orden de mayor a menor). Los grupos de investigación clasificados en categoría B y C tienen conocimiento moderado en los cinco tipos de capital humano.

The need to increase the depth of processing of petroleum and hydrocarbon-containing raw materials entails the need for qualified processing of residual products in order to use them more efficiently. This paper shows the role of the delayed coking unit in the processing of heavy oil residues and the deepening of oil refining, as well as the state of the global and Russian market for coke production and consumption. The analysis of various heavy oil residues according to the initial physico-chemical characteristics is carried out. The material balances of coking at the laboratory installation of both individual heavy oil residues and raw mixtures have been compiled. Graphical dependences of the output of coking products on the ratio of the initial components of raw materials are established and constructed. A number of promising areas of research for further improvement of the process are identified. The obtained data can be used in production planning in order to select the optimal composition of the raw material pool, the raw materials of the refinery as a whole, and the quality requirements of the products obtained.

The oil and gas industry is one of the most important branches of the national economy. It differs from other branches of the fuel and energy complex in high capital investments and long construction and operation periods. One of the main tasks in gas industry enterprise management is the most efficient use of capital investments, which requires the adoption of informed decisions in oil and gas asset management. Gas industry enterprises include a large number of hazardous production facilities, accidents and incidents at which are the most dangerous for both personnel and population in general, as well as for the industry companies themselves. Emergencies at facilities can lead to financial and reputational losses, as well as damage the health and life of people and the environment. Therefore, the issue of planning measures for prevention, as well as localization and elimination of the accident consequences, is considered one of the priorities.The presence of video surveillance at production facilities is an integral part of an integrated security system. High-quality video surveillance helps to identify deviations in automated processes in a timely manner and take measures to eliminate failures and violations. Timely and rapid response to emergency situations prevents the occurrence of an accident, as well as prevents socio-economic damage.The authors have conducted many studies in the sphere of analysis of the organization of localization and liquidation of emergency situations and the effectiveness of personnel response in emergency situations at hazardous production facilities. Besides, studies of video surveillance systems in Gazprom UGS LLC branches – Departments of Emergency Recovery and Well Overhaul – have been conducted. Gazprom UGS LLC is the only operator of 23 underground gas storage facilities on the territory of the Russian Federation. Most of the Company's production facilities are located at a considerable distance from settlements and other infrastructure facilities, which increases the response time to emergency situations, and as a result, may lead to an emergency situation. Therefore, it is necessary to constantly control and monitor the integrity of the system. The authors have made conclusions about the need to improve existing video surveillance systems and expand their use at other branches of the Company.
