Пульсаційні теплові труби (ПТТ) є високоефективними теплопередавальними пристроями та одним із найновіших видів теплових труб. Одним із перспективних напрямків їх застосування є використання у якості основних теплопередавальних елементів рекуперативних теплообмінних апаратів, що знайшли широке застосування в енергетиці, енергозбереженні, хімічній та харчовій промисловості. Cеред актуальних напрямків досліджень в області таких теплообмінників важливим є вивчення впливу витрат теплоносіїв на характеристики цих апаратів. Для кращого розуміння цих впливів доцільно проводити подібні дослідження не тільки на теплообмінних апаратах в цілому, але і на їх основних елементах, тобто пульсаційних теплових трубах.
В роботі приведено результати експериментальних досліджень впливу витрати охолоджуючого середовища на теплопередавальні характеристики мідної одновиткової замкненої ПТТ з теплоносієм водою та коефіцієнтом заповнення 45%. Внутрішній діаметр ПТТ складав 3,1 мм, загальна довжина – 212 мм, довжина зони нагріву – 70 мм, довжина зони конденсації – 142 мм. ПТТ було досліджено у вертикальному положенні з нагрівом знизу в діапазоні підведених теплових потужностей 10-140 Вт. Витрата охолоджувальної води складала 2,9-7 г/с, а її температура 10-15°С. В результаті проведених досліджень було з’ясовано, що при витраті 2,9 г/с перепад температур та термічний опір ПТТ на 20-22% нижчий, а переданий тепловий потік на 35% більший, ніж при вищих значеннях витрати. При цьому зміна витрати в діапазоні 4,5-7 г/с не здійснює помітного впливу на перепад температур та термічний опір ПТТ. Виходячи з цього, для збільшення коефіцієнту теплопередачі в теплообмінних апаратах на ПТТ можна рекомендувати зменшення витрати холодного теплоносія.

Розглянуто проблеми екоіндустрії та інноваційні шляхи розвитку агропромислової сфери. Показано перспективи технологій глибокої переробки сировинних відходів при виробництві соків та екстрактів. Визначено недоліки традиційного обладнання для зневоднення сировини реологічної структури. Наведено приклади широкого використання в різноманітних задачах зневоднення установок із інфрачервоними джерелами енергії. Сформульовано гіпотезу о перспективах використання електромагнітних джерел енергії в технологіях зневоднення відходів при переробці рослинної сировини. На базі параметричної моделі процесу зневоднення у інфрачервоному полі методами теорії подібності отримано структури критеріальних моделей для рухомого та нерухомого шару сировини. Об’єктами експериментальних досліджень були макуха буряка, цибулі, яблук, дині, абрикосу, полуниці, винограду, банану, сливи та томатна паста. Експериментальний стенд включав холодильну машину, вакуумну систему, джерела електромагнітної енергії, комп’ютеризовану систему збору та обробки інформації. Новими науковими результатами є функціональні залежності по кінетиці зневоднення об’єктів досліджень, термограм процесів та лінії швидкості сушіння. Комплекс проведених експериментальних досліджень визначив перспективність технологій інфрачервоного зневоднення сировини. Запропоновано методологію порівняння енергетичної ефективності технологій із різними по природі джерелами енергії. Порівняння проводиться по ефективності використання 1кг первинного палива. Всі енергетичні потоки нормуються до палива. Наведено енерготехнологічні схеми традиційної конвективної сушарки та інноваційної із інфрачервоними джерелами енергії. Показано, що відсутність в інноваційній сушарці втрат енергії із викидами сушильного агенту підвищує ефективність використання енергії палива на 30 %.
¿Cuál es el estado del arte de la aplicación de Design Thinking en la educación superior? Una revisión de alcance de la literatura

Published: December 2022

Design Thinking (DT) sigue siendo un concepto difuso, así como sus resultados. Esto motivó la presente revisión de alcance de la literatura (2008-2022), en la cual se aplicó el marco de Arksey y O'Malley. Usando la plataforma Web of Science, se obtuvieron 2853 artículos, de los cuales solo 172 cumplieron con los criterios de inclusión y exclusión. Los resultados muestran que: (a) No existe un acuerdo en la definición de DT. (b) Hay una variedad de herramientas, técnicas y modelos utilizados para aplicar DT. (c) Las habilidades más comunes -asociadas a intervenciones de DT- son creatividad, trabajo en equipo y resolución de problemas. Solo 100 de 172 estudios incluyeron evaluaciones de las intervenciones de DT. Los instrumentos de investigación se basaron principalmente en auto reportes de estudiantes. La mayoría de los estudios empíricos reportaron un impacto positivo. (d) Solo 12 estudios empíricos involucraron grupos de control, mientras que 37 adoptaron un diseño de evaluación pre-prueba con post-prueba. Se encontró que las intervenciones de DT duraron desde 90 minutos hasta un año. La mediana del número de participantes en las intervenciones fue de 47. DT presenta una agenda de investigación interesante, pero también existe la necesidad de más estudios robustos, basados en evidencia.
¿Cómo se sitúan las escuelas rurales catalanas ante la dimensión territorial? Una mirada desde sus proyectos de centro
Authors: Carrete-Marín Núria , Buscà Francesc 
Published: December 2022

La escuela rural del siglo XXI deberá de adoptar un papel fundamental como motor en el desarrollo local y como generadora de capital social y, por tanto, los proyectos de centro han de incluir la dimensión territorial, trabajando conjuntamente con la comunidad y los agentes locales, para promover la equidad y reducir desigualdades en estos contextos. El presente artículo tiene como objetivo analizar la presencia de la dimensión territorial a través de un estudio transversal centrado en el análisis de los documentos de centro de una muestra representativa de 193 escuelas rurales catalanas. Los resultados evidencian que, a pesar de la existencia de proyectos educativos y buenas prácticas que confirman el tratamiento de la dimensión territorial desde la ruralidad, la mayoría de las páginas web de los centros no reflejan con claridad ni su intención ni como sus prácticas educativas lo consiguen. Tampoco muestran si este tratamiento se desarrolla en colaboración con la comunidad educativa y las entidades locales. Las conclusiones refieren a la necesidad de considerar mejoras en la visibilidad del trabajo de dimensión territorial en la escuela.
Deriving Site Effect-Free Hard-Rock Time Histories in Japan from the Generalized Inversion Technique
Authors: Pilz Marco , Cotton Fabrice , Zhu Chuanbin , Nakano Kenichi , Kawase Hiroshi 
Published: December 2022

ABSTRACTA key component in seismic hazard assessment is the determination of time histories for hard-rock site conditions, either as input motion for site response computations or for applications to installations built on this site type. The state of the practice is to apply physics-based corrections for removing site effects from surface recordings to obtain the underlying bedrock motion. Here, we propose and test the use of the generalized inversion technique (GIT) for deconvolving surface recordings to hard-rock time series at the amplification-free seismic bedrock. As part of the proposed procedure, an event-specific phase scaling method is presented, which allows changes in signal duration to be considered. For validation purposes, we select a total of 90 Kiban–Kyoshin network (KiK-net) surface-downhole sites having no significant velocity contrasts below their downhole sensors and with the latter being located at sufficient depth so that they are not impaired significantly by downgoing waves. We evaluate the effectiveness of the empirical predictions by comparison with recorded time series at the downhole sensors. We find quite high correlations and small variations in both spectral shape and amplitude over the entire frequency range for the GIT deconvolution at the majority of the 90 KiK-net sites with all mean residuals less than 0.25 in contrast to empirical and 1D modeling approaches, which significantly overestimate the level of hard-rock ground motion for frequencies larger than a few Hertz.
Stomach versus heart: case report of a giant hiatal hernia with perforated gastric ulcer with obstructive shock
Authors: Sanchez Yankel A. , Ayub Omar Z. 
Published: December 2022

A giant paraesophageal hernia is defined when at least 30% of the stomach has moved to the thorax or the presence of another intra-abdominal organ. We describe the presentation of a clinical case of a giant hiatal hernia with perforated gastric ulcer in a 52-year-old man who presented to the emergency department with pain in the inguinal region developing obstructive shock. Presentation of hiatal hernias is usually asymptomatic and in some cases with atypical signs and symptoms involving cardiovascular and respiratory disorders. In patients with a history of gastroesophageal reflux disease/ with atypical thoracic symptoms, hiatal hernia and its complications should be ruled out.

A pesquisa teve como objetivo analisar os impactos causados pela pandemia covid-19 na saúde mental dos trabalhadores em teletrabalho. Foi uma pesquisa mista, cuja metodologia contou com uma combinação de técnicas e procedimentos qualitativos e quantitativos. Participaram do estudo 197 trabalhadores, com idade média de 38,47 anos. A coleta de dados ocorreu através de um questionário autoaplicável online, cadastrado na plataforma google forms. A disponibilização do link da pesquisa ocorreu por meio de redes sociais e da busca por parceiros como sindicatos, associações empresariais e setores de recursos humanos para a distribuição aos potenciais participantes. Os dados foram submetidos à análise temática, gerando quatro categorias. Os resultados evidenciaram sofrimento e danos psicossociais, bem como impactos negativos nas relações socioprofissionais. Além disso, os dados apurados demonstraram carência de apoio especializado de escuta e suporte, assim como falta de auxílio financeiro para as tecnologias necessárias ao adequado desempenho laboral. Alguns pontos positivos puderam ser percebidos, como se sentir protegido e em segurança, com mais tempo livre e oportunidade de novos aprendizados. Apesar disso, concluiu-se que os danos à saúde mental se sobressaíram, demandando políticas públicas e fortalecimento da legislação trabalhista.

Abstract
During the COVID-19 pandemic, the emergence of the infodemic and vaccine hesitancy posed a significant challenge to adequate vaccine uptake. In response, conversational AI services such as chatbots have become an increasingly popular tool in the field of health service delivery and communication to increase individuals’ health literacy and vaccination intention. However, few studies have performed a rigorous evaluation of the effectiveness of chatbots as a means of improving vaccine confidence and acceptance. In Thailand, Hong Kong, and Singapore, from February 11th to June 30th, 2022, we conducted multisite randomised controlled trials (RCT) on 2,045 adults with unvaccinated dependent family members who were vulnerable (i.e., seniors) and had been refusing/delaying vaccination, or newly eligible for vaccines (i.e., children). After a week of using multilingual COVID-19 vaccine chatbots, the differences in vaccine confidence - measured by the Vaccine Confidence Index - and acceptance were compared between the intervention and control groups. Factors of vaccine confidence and acceptance were explored. Compared to non-users, a smaller proportion of chatbot users reported a decrease of confidence in vaccine effectiveness in the Thailand child group [Intervention: 4·3% vs. Control: 17%, P = 0·023] and Hong Kong child group [10% vs. 26%, P = 0·034], and of vaccine effectiveness in reducing severe conditions in the Thailand senior group [12% vs. 21%, P = 0·024]. There was no significant change in vaccine confidence or acceptance in the Singapore child group and Hong Kong senior group. Employing the RE-AIM framework, process evaluation indicated strong acceptance and implementation support for vaccine chatbots from stakeholders, with high levels of sustainability and scalability. This study was the first multisite, parallel RCT on vaccine chatbots and reported mixed success in improving vaccine confidence and acceptance among highly hesitant Asian subpopulations. Deploying chatbots as a complement to existing vaccination strategies could identify users’ main concerns for rejecting/delaying vaccination and facilitate a targeted communication and engagement strategy.

Published: December 2022

Abstract
Background: Healthcare waste (HCW) is considered one of the most hazardous waste globally. Healthcare waste management is a neglected issue in hospitals of developing countries due to poor practices among health staff. Trainings of health workers have been proven to be one of the most effective strategies for improving the practices and health behavior
The aim of this study was to assess HCWM before and after repeated training sessions in Sahloul University Hospital (2019-2021).
Methods: A pre experimental study, based on two audits of HCWM, was carried out at Sahloul University Hospital (2019-2021). The data collection was carried on three stages over two different years.
Results: Concerning the audit of ressources; Between the year 2019 and 2021, we noted an improvement of the some of ressource indicators such as “Presence of yellow bags in sufficient numbers” (54.9% VS 83.3%; p=0.003); “Presence of black bags in sufficient numbers” (63.9% VS 82.18%,p=0.003) or “Presence of wheeled trolley for HCW transport” (34.1% VS 82%, p<10-3).
The audit of practices was carried out in 160 units in 2019 VS 132 in2021. There has been a marked improvement in the sorting of HCW between pre- and post training.
In fact, the overall compliance rate for sorting sharps has gone from 60.3% to 77.6% (p <10-3) while that of sorting soft and solid waste from 32.5% to 72.4%, (p <10-3) in 2021.
The overall compliance rate for the intra-service collection step passed from 31.3% to 58.2%., we noted a persistence of inadequacies in the labeling of containers and bags as well as the traceability of the time of HCW collection.
Conclusion: The provided training courses were effective; indicating a significant improvement of healthcare workers adherence to recommended practices of HCW management. Nevertheless, there are still some indicators to be improved.
Envisioning a culturally safe midwifery model from the perspective of Indigenous families: A case study of midwifery care in inner city Winnipeg, Manitoba, Canada
Authors: Wiscombe J. Dawn , Shukla Shailesh 
Published: December 2022

Abstract
Background Our research paper explores the concept of cultural safety and it’s practical implications in a midwifery-led prenatal care model designed to improve access to prenatal care for Indigenous people in inner-city Winnipeg. While previous studies suggest midwifery care as a facilitator to access to prenatal care for Indigenous families, there have been no studies performed to date specifically about the role of culturally safe midwifery care in inner-city Winnipeg.
Methods We we focused on using Indigenous research methodologies to ground the research in an Indigenous world view. We used Two-Eyed Seeing as a reflective engagement tool with Indigenous midwifery clients to understand how midwives and other care providers can shape the quality of prenatal care services to meet the needs of local Indigenous families more effectively, and in a culturally safe manner.
Results The results show that the Mount Carmel Clinic (MCC) midwifery model is on a continuum of culturally safety, which contributes to feelings of trust and comfort, and encourages families to attend for prenatal care. The model of care could facilitate a deeper level cultural safety by expanding the care team to include Indigenous members and access to traditional knowledge about pregnancy, birth and parenting.
Effects of an acute dose of antioxidants on glucose metabolism at rest, during exercise, and during a glucose load in healthy young subjects: A randomized, placebo-controlled, double- blind crossover trial
Authors: Rodriguez Ivan , Espinosa Enma Veronica Paez , Cofre Cristian , Álvarez Cristian , Zbinden-Foncea Hermann , Castro-Sepulveda Mauricio 
Published: December 2022

Abstract
Background: Reactive oxygen species (ROS) regulate glucose metabolism (GM) by improving the translocation of GLUT4 in skeletal muscle and pancreatic beta cells in vitro. ROS triggered by exercise promotes GM regulation. Antioxidant supplementation could block these beneficial effects, altering these processes during exercise. However, there is limited evidence in humans on whether antioxidant intake affects GM. Therefore, we investigate the effect that a high dose of antioxidants (HDA) has on GM.
Methods: Two trials: 60 minutes before an endurance exercise bout (EEX) and 60 minutes before an oral glucose tolerance test (OGTT), ten healthy and physically active male subjects (age, 25.3 ± 4.2; HOMA-IR, 1.3 ± 0.43; VO2max, 50.6 ± 8.12 mL•kg-1•min-1) consumed a high dose of antioxidants (HDA, 1000 mg of Vitamin C, 600 IU of Vitamin E, and 600 mg of α-lipoic acid) or placebo (2000 mg of talc) before each trial. Trials were 7 days apart and consisted of 1) 60 minutes of endurance exercise at 60 % of Vo2max and 2) 60 minutes of OGTT (75 g). Measurements of gas exchange and capillary blood samples were collected every 15 minutes during both trials.
Results: Ingestion of antioxidants (AOC) by the participants in the trial showed higher resting blood glucose than the placebo (AOC, 95.5 ± 7.6; placebo, 87.4 ± 6.4 mg/dl-1; P = 0.03). During endurance exercise (EEX), AOC modified carbohydrate oxidation (CHOox) with respect to time (time, P < 0.001; group, P = 0.11; time x group interaction, P = 0.03), showed no changes in lactate or glucose concentration. During OGTT, AOC trial showed a decrease in blood glucose concentrations with respect to time (time, P = 0.001; group, P = 0.17; time x group interaction, P = 0.06), without changes in blood lactate or CHOox.
Conclusion: An acute dose of antioxidants increases the glycemic level at rest and (CHOox) during EEX in healthy subjects.

Published: December 2022

Abstract

Soybean meal (SBM) is the most widely employed vegetable ingredient in aquafeeds, but its rising price and the negative environmental impacts of its cultivation open research efforts for its replacement. More sustainable aquaculture may be achieved by utilizing agricultural and fishery by-products; thus, this study aims to incorporate pea meal (PM) and shrimp protein hydrolysate (SH) as protein ingredients in tilapia juveniles’ feed. The presence of protease inhibitors and the in vitro digestion were evaluated for raw (PM0) and extruded pea meals (PM150), while SH characteristics were studied as well. The nutritional quality of alternative ingredients was assessed to formulate a diet that meets tilapia juveniles’ requirements, and its effects on growth were evaluated. Extrusion significantly reduced the PM inhibitory effect on tilapia proteases (from 5.4–1.9%). In vitro protein digestion of PM150 (7.8 ± 1.35%) did not differ from the control treatment with fish meal (FM; 11.8 ± 1.94%). Additionally, SH presented 41.6 ± 2.91% of DPPH radical scavenging activity. Tilapias fed with a diet where SBM was totally replaced by the dietary inclusion of 25% PM150 and 10% SH, presented comparable growth indicators to those exposed to the control diet. Extrusion reduced PM proteolytic inhibitory effect and improved protein digestibility. SH presented antioxidant effect, as well as, provided flavor enhancers and essential amino acids to the diet. It is feasible to achieve a sustainable dietary formulation for juvenile tilapia using the evaluated by-products without affecting its growth performance.
Frontline and forgotten: Community nurses’ experience of shielding during COVID-19
Authors: Stenson Sophie , Arfanis Konstantinos 
Published: December 2022

Abstract

In March 2020, the COVID-19 pandemic reached the United Kingdom. National and local lockdowns became the new reality as the pandemic had a significant effect on morbidity and mortality, especially amongst vulnerable groups of the population. It was people in these groups in particular that were advised to shield at home. There are a number of studies focusing on the psychological effect of this enforced isolation on the general population; however, to the researchers’ knowledge, the effects shielding on healthcare professionals has not received a similar level of attention. The general population has expressed its appreciation to frontline healthcare professionals, with the majority of praise directed towards doctors and nurses working for the National Health Service. It must be noted that community nurses working for the private sector do not appear to have been officially afforded the same recognition, and research on the psychological effect the pandemic had on these healthcare professionals is lacking. The primary researcher identified this gap in the literature which became one of the reasons for the present study. This study enlisted the participation of ten community nurses working in the private sector who experienced shielding due to a long-term health condition. Participants were all female and aged between 24 and 63 years, and each attended a semi-structured interview. These interviews consisted of nine open-ended questions exploring these nurses’ experiences and the psychological effects COVID-19 and shielding had on them. Grounded Theory was favoured as the analytical technique, identifying eleven core themes. Social Identity Theory informed the evaluation of the data. Nurses reported an array of, psychological effects, varying from mild to severe. According to participants, employer recognition and staying connected with colleagues are vital for the maintenance of their social and professional identity and, psychological well-being.
