Las estrategias multiplataforma de Euskal Irrati Telebista para las nuevas audiencias: los retos de una televisión pública en lengua minoritaria
Authors: Mendieta Bartolomé Ana
Published: February 2023

La industria audiovisual y los hábitos de consumo han sufrido una profunda transformación tras la incursión y el consecuente monopolio de las plataformas de distribución de contenidos en línea (OTT). Las audiencias infantiles y juveniles cada vez acceden menos a las televisiones públicas, a lo que se une el descenso imparable de sus audiencias. En el caso de la radiotelevisión pública vasca (EITB), su cuota de pantalla se ha reducido a más de la mitad desde 2004, por lo que la digitalización de sus contenidos en múltiples pantallas es una cuestión de supervivencia si quiere competir con las grandes plataformas. Este trabajo se propone describir las recientes estrategias multiplataforma de EITB para captar nuevas audiencias y comprobar si se corresponden con su mandato de servicio público, tanto para promocionar el euskera como para priorizar a su público estratégico infantil y juvenil.

Objetivo: Avaliar o impacto do ultrassom point-of-care (POCUS) transtorácico no tempo de pausa entre as compressões torácicas durante a reanimação cardiopulmonar. Métodos: Revisão sistemática da literatura nas bases de dados PubMed, Embase, Scopus e Biblioteca Virtual em Saúde. O desfecho primário da metanálise foi a diferença no tempo de pausa entre as compressões torácicas. O desfecho secundário foi o retorno da circulação espontânea dos grupos de verificação manual e POCUS transtorácicos. O software R versão 4.1.3 foi utilizado para realizar todas as análises estatísticas. A diferença no tempo de pausa foi expressa por meio da diferença de média (MD) com intervalo de confiança de 95% e o retorno à circulação espontânea por meio do risco relativo. O p-valor foi considerado estatisticamente significativo quando < 0,05. Resultados: A pesquisa nas bases de dados resultou em 6177 publicações, no entanto, apenas cinco foram incluídas. Houve uma associação estatística entre o uso de POCUS e pausas mais longas entre compressões torácicas com uma MD de 3,88 (95% CI 2,76; 5,01; p-valor < 0,0001). A exclusão adicional de qualquer um dos cinco estudos não alterou o resultado, ou seja, o DM entre os dois grupos continuou a ser estatisticamente significativo. Conclusão: A análise combinada dos dados sugere que a utilização do POCUS aumenta o tempo de pausa entre as compressões torácicas numa média de 3,88 segundos. Contudo, são necessários estudos randomizados controlados que avaliem o impacto no retorno à circulação espontânea.

Electrical discharge machining is one of the most common processes for processing metallic materials. This process is characterized by the lack of mechanical pressure on the object that ensures the macroscopic location of the erosive agent. This scientific paper highlights a study based on experimental data processing as well as modeling the most important technological parameters for dimensional processing by electrical discharge machining with and without magnetic activation. In this context, the modeling and optimization of process parameters is approached, which can lead to the quality increasing of the processed surface, to an increase of the processing productivity and to a reduction of the volume wear of the transfer object used.

In the last years, technology experienced an exponentially increase, but no matter how much the aviation manufacturers tried to automate the flight activity, events with major implication for flight safety continue to appear. In over 80% of the aviation accidents, the limited performance of the pilots, technicians and air traffic controllers played a major role. The purpose of this study was to analyse the factors which influence the human performance in all stages of flight, taking into consideration 4962 aviation events from 2000 to 2020, downloaded from Aviation Safety Reporting System (ASRS). Nowadays, the perspective of the 4th industrial revolution constrains us to insist on using big data for much more complex analyses and much more accurate results.

The work aims to increase the quality of the sheet metal embossing process used for car door caissons manufacturing.In order to obtain parts without defects, the cause of the defects, the moments in which they appear and the process conditions that favor their appearance are studied. For the processing of parts with complex and irregular shapes, optimal conditions for the flow of the material are necessary. If the degree of deformation is small, the stamping must be done by stretching the material and, therefore, retaining ribs must be provided. Thus, the edges of the semi-finished product are retained and the central part of the part will be subjected to a stretching process, thus avoiding the elastic return and ensuring the stability of the shape of the part

The interaction between a turbulent jet and free stream flow is computationally studied using the large-eddy simulation (LES) approach. The effect of the blowing-ratio on the turbulent mixing is also subject of investigation in this research. The study revealed that the LES approach is suitable for the computation of highly-turbulent flows and able to capture all the flow structures of the jet in cross-flow. The analysis showed that the blowing-ratio is one of the parameters that control the turbulent mixing. Thus, the increase of the blowing-ratio causes a deeper penetration of the jet into the free stream flow and hence, an increased turbulent mixing. The interaction between the jet and free stream flow causes a sequence of vortex rings of different length-scales. Thus, larger vortex rings were observed for higher blowing –ratios. A concluding remarks of the present research is that high-turbulent mixing requires higher blowing-ratios.

Oral supplementation of Ilex paraguariensis extract and eggshell membrane exhibit beneficial effects on the skin of mature male rats
Authors: Ramirez Maria R. , Rintoul Ignacio , Leiva Manuel , Molli José S. , Yori Juan C.
Published: February 2023

Context: Ilex paraguariensis (IP), a South American plant mostly consumed as an infusion, contains several phytocompounds with demonstrated positive effects on skin health and photoprotective properties. Eggshell membrane (ESM), a by-product of the poultry industry, also presents photoprotective properties. Both IP and ESM contain compounds that absorb ultraviolet radiation (UVR) and stop the mechanisms by which UVR damages the skin. The synergistic effects of these natural products on the reparation of skin structure and dermal collagen production deserves to be investigated. Aims: To determine to what extent the oral supplementation of IP and ESM, administrated individually or in combination, promotes beneficial effects on the skin of mature Wistar rats. Methods: The chemical composition of IP and ESM and the spectrophotometric solar protection factor (SPF) of the IP extract were characterized. In vitro, antioxidant and anti-inflammatory effects were assessed using erythrocytes. In vivo investigation consisted of macro and microscopic image analysis and diagnosis of the skin of the dorsal region of rats. Results: The IP extract showed low SPF capacity combined with a protective effect against AAPH-induced erythrocyte haemolysis. IP extract inhibited erythrocyte haemolysis induced by both hypotonic solution and heat. The antioxidant and anti-inflammatory activity of the IP could be explained in terms of its membrane-stabilizing properties. Histologic analysis showed an increase in the collagen content of the skin of supplemented rats. A clear synergistic increase in collagen levels resulted when IP and ESM were administered together. Conclusions: IP and ESM are beneficial for skin health, present synergistic effects, and could be used as ingredients in oral cosmetics.

Authors: Onyimba I. A. , Labaran Y.
Published: February 2023

In line with increasing demand by consumers for safe and minimally processed food products, biopreservation has been advocated over the traditional use of chemical additives in combating food spoilage. This study evaluated the antibacterial activity of four lactic acid bacteria (LAB) (Lactobacillus fermentum, Lactococcus lactis, Lactobacillus brevis and Lactobacillus plantarum) isolated from kunun-zaki against the bread rope spoilage bacteria, Bacillus subtilis and Bacillus cereus. Antibacterial activity was determined using the dual agar overlay method with subsequent measurement of zones of inhibition. Titrimetric methods were used to determine the abilities of the isolated LAB to produce antimicrobials including lactic acid, hydrogen peroxide and diacetyl. Lactobacillus fermentum brought about the highest inhibition zone (20 mm) against Bacillus cereus. The smallest zone of inhibition (6 mm) was recorded for L. plantarum against B. cereus. Whereas L. plantarum produced the highest amount of lactic acid (0.540 g/L), L. brevis produced the lowest lactic acid amount of 0.348 g/L. L. fermentum produced the highest amount of hydrogen peroxide (0.020 g/L) whereas L.brevis recorded the lowest hydrogen peroxide production of 0.010 g/L. L. lactis and L. fermentum had the highest and lowest values of 0.649 g/L and 0.219 g/L respectively for diacetyl production. Differences in the antibacterial activities and antimicrobials production by the LAB were statistically significant (P < .05). The findings show that the LAB isolates possessed antibacterial activity against the selected spoilage bacteria and as such could be exploited as potential biocontrol agents against the selected bread rope spoilage bacteria.

Male Circumcision: History of Current Surgical Practice
Authors: Militello Claudio , Pais Veronica
Published: February 2023

One of the most frequent procedures carried out on men, whether for medical or religious reasons, is circumcision, which involves the removal of the foreskin. The procedure’s introduction in various locations and times allowed for the development of a surgical approach that is now adapted to minimize problems and deliver obvious medicinal benefits. Male circumcision is currently a hot topic of dispute because of ethical, legal, and scientific concerns, as well as the procedure’s various roles: therapeutic, preventive, and ritualistic. The practice’s origins can be traced back to ancient times, but it is still a surgical procedure used to prevent HIV transmission today. In order to lower the risk of HIV transmission in men, the WHO advised considering male circumcision in 2007. The purpose of this article is to describe the procedure of circumcision throughout history.
Production of Potato Quality Seeds in Mountainous Region of Central Africa
Authors: Ishibwela Obedi Nyamangyoku
Published: February 2023

Potato production in the mountainous region of Central Africa (CA) remains very low (10–15 T/ha), while the commonly cultivated varieties have a genetic potential to reach more than 40 T/ha. This low productivity is due, among other reasons, to a low quality of propagation material (seed tubers). Certified potato seed tubers are not only expensive but also not sufficient on the market to cover the needs of potato producers, leading them to use year-to-year seeds potatoes already infected by diseases and totally degenerated. Due to constraints of getting appropriate facilities for good Potato seeds production among producers, various cutting methods to obtain quality potato seeds have been developed. Indeed, in several experiments carried out in Rwanda and in other countries, the use of good healthy propagation material has increased yields by more than 35%. Since this mountainous zone of Central Africa is very suitable for the cultivation of potatoes for its climatic conditions, the methods developed in this chapter for producing quality potato seeds and appropriate agricultural practices (crop rotation, good fertilization, disease control and pests) will make it possible to significantly increase yields, and thus allow the varieties grown in Central Africa to express their genetic potential of more than 40 T/ha.

Authors: Ojo Nehinbe Joshua
Published: February 2023

Spectacular developments that were recorded in the field of software engineering in recent years have led to the influx of software industry with series of computer apps such as dating apps, games apps, entertainment apps, banking apps, Photoshop apps, meetings and virtual conferencing apps. Studies have shown that most computer apps are widely accessible to adults and juveniles to download and effortlessly navigate through them. However, researchers have now revealed the existence of malware apps as new groups of computer apps that are strongly competing with legitimate computer apps and the latest rates at which some juveniles can adopt them to commit crimes. These discoveries have raised serious doubts about the elements of the crimes, the circumstances that surround vulnerable children to commit the crimes and how these dilemmas are rarely buttressed by pragmatic studies over the years. This chapter adopts mixed methods to critically explore the above issues. Qualitative interviews of 60 teenagers (between the ages of 10 and 17) and 20 grown-up children (between the ages of 18 and 22) together with 5 professionals were carried out. The analysis extended the generic elements of juvenile crime and raised new legal dilemmas regarding the concepts of transfer of criminal liability, compelled (or obligated) liability, ‘act’ that constitutes juvenile crimes and the restrictive applicability regarding criminal consent of extremely young children that are still under the tutelage and guidance of their parents.

A Review of Digital Learning and ESL Online Classroom Experience in Higher Education
Authors: Lo Noble
Published: February 2023

Whilst universities across the global community had adopted new digital learning standards prior to COVID-19, the radical effect of quarantines and social distancing on remote learning needs has fundamentally altered the structure of modern English as a second language (ESL) education in higher education institutions. The current investigation critically explores the educational paradigm from a perspective of content dissemination, learning best practices, and knowledge acquisition in Hong Kong colleges and universities. Through a critical review of the literature surrounding digital learning challenges and opportunities, evidence revealed an overlapping proposition of adaptation and discipline which many students lacked prior to the COVID-19 interruption. By comparing the perspectives of 1062 students across ESL programmes taking English for academic purposes (EAP) and English for specific purposes (ESP) courses within several Hong Kong institutions, this study has confirmed the potential advantages of digital learning solutions including time management, self-paced learning, and knowledge engagement. Students were surveyed using a digital, structured questionnaire to capture a robust representation of experiences during the COVID-19 pandemic and their effects on student learning outcomes. Through quantitative analysis, student feedback has confirmed several developmental challenges related to skills gaps, personal discipline, environmental forces, and student learning expectations. Based upon these findings, a revised protocol for digital citizenship has been proposed which focuses on core principles of self-accountability and discipline that evolve out of proactive, motivated learning objectives that link students to their digital identity and role. Ultimately, these observations indicate a need for future assessment of the competing motivations shaping student engagement in digital learning services and traditional classroom offerings as the COVID-19 pandemic restrictions are lifted and the educational industry evolves towards its new normal.

Authors: Ibrahim Ayman , M.P. Cattaneo Tiziana , Amer Alia , Helyes Lajos
Published: February 2023

Undoubtedly, rapid population growth has sharply increased global food demand. Although the green revolution, accompanied by food industrialization practices, helped a lot in meeting this demand, the food gap is still huge. Regardless of COVID-19, due to that 14% of the world’s food is lost before even reaching the market, and thus the food insecurity prevalence by rate (9.7%), where the food losses are valued at $400 billion annually according to FAO. In the face of such issues related to food insecurity and food losses, drying technology since its inception has been known as the most common operation in food processing and preservation. However, the excessive use of the drying process and exposure to heat for long periods led to a severe deterioration in the physicochemical quality characteristics of these products. At the same time, growing attention on human health through monitoring the quality and safety of food to avoid chronic diseases led to increasing awareness of the consumer to obtaining products with high nutritional value. Therefore, there has been a great and rapid evolution in drying technology to preserve food with high quality. Hence, this chapter aims to shed light on the drying technology evolution in food processing and preservation as one of the most important post-harvest treatments in the agriculture field.
Innovative Methods in Computer Science Education
Authors: Pusztai Kinga
Published: February 2023

With the appearance of rapid technological changes, the culture of receiving and communicating information, as well as attention, has also changed. Some of the pedagogical methods that were well-proven a few decades ago have now become obsolete. It is important to replace them with new methods that are related to the views of the Z and alpha generations. This chapter deals with the innovation of the ELTE IK Computer Science B.Sc. subject. My innovations are related to the method of digital storytelling and gamification. Besides a brief description of the methods, I will present the changes implemented in my courses, such as making videos or the use of edutainment applications. My innovations have been studied over five semesters, researching students’ feedback on the changes and modifying some elements based on students’ feedback. Furthermore, I was also curious about the changes’ impact on students’ results. From my research, it is clear that the introduced tools motivated the students to spend more time learning the subject, leading to deeper mastery.

Authors: Nakov Natalija , Acevska Jelena , Brezovska Katerina , Kavrakovski Zoran , Dimitrovska Aneta
Published: February 2023

The global need for changing the processes in order to meet the green analytical chemistry (GAC) criteria is a great challenge for the pharmaceutical industry. High-performance liquid chromatography (HPLC), as one of the most frequently used techniques in various stages in the pharmaceutical industry, generates huge amounts of organic toxic waste. Therefore, the implementation of the GAC principles in pharma analysis is highly required. Although the number of published papers concerning green chromatography approaches is constantly increasing, the use of eco-friendly HPLC methods in the pharma industry has not been widely implemented. The reasons for this mainly include the need for adaptation of the conventional HPLC instruments, lack of time, lack of experience, or uncertainty of the analysts regarding fulfillment of the method criteria. In this chapter, an overview of green strategies that can be easily applied to conventional instruments for liquid chromatography (LC) in developing eco-friendly HPLC methods in pharma analysis is given. The aim is to emphasize that the green method development in pharma analysis can be easily accomplished and to encourage the analytical community in the pharmaceutical industry not only to develop but also to transfer the already established conventional HPLC methods into green ones.
Violence and Its Antidotes
Authors: Lei Jun
Published: February 2023

This chapter further draws on strands of scholarship both within and outside of Chinese studies. It engages poststructuralist theories of gender, sociological theories of masculinities, and postcolonial theories of uneven transcultural exchange between the East and the West. More importantly, this chapter advances a new series of theoretical conceptualizations including “differentiation” (strategic positioning and gender performance), “negation” and “affirmation” (two indispensable mechanisms in the appropriation of Others in pursuit of global recognition), and “feminine space” and “brutalization of scholars” (two complex parameters to examine the reformulation of intellectual masculinities).
Consuming the Modern Girl
Authors: Lei Jun
Published: February 2023

This chapter focuses on the New Sensationalist school of writers Liu Na’ou and Mu Shiying whose worked gained popularity in Shanghai in the turbulent era of the late 1920s to the mid-1930s. It analyzes how race, class, and gender intersected within the cosmopolis where Chinese male authors became part of what was then considered middleclass urban professionals. The neo-sensationalists took issues with tension of urban life as middlebrow men experienced it, specifically in terms of the emasculation complex elicited by both an unfulfilled desire for the Modern Girl and the oppressive racial and class hierarchies of the semi-colonial city. The textual tactic of “surrogate violence” allows the authors to confront the inner conflict about violent means to achieve masculinity: he can simultaneously engage with a fantasy of violence and its sensations through the surrogate on the one hand, and with the judgement and disparagement of it, on the other.
International practice of capacity building in engineering education: a comparative case study

Capacity building is a corner stone for having well prepared and effective teaching staff in engineering education. Despite the importance of capacity building in engineering education, there is relatively little research on this topic. In this paper, we address this gap by reporting on an international comparative study on capacity building practices in university-level engineering education. We examine how capacity building is organised in seven European institutions (in Belgium, Finland, France, Germany, Hungary, Sweden, UK) and Australia, based on institutional education policies and practices. We compare the preparation of teaching staff, their initial training, and continuing capacity building activities throughout their careers. To do this, we applied a qualitative approach, collecting data through (1) a structured questionnaire answered by the members of the SEFI SIG on Capacity building and (2) written notes produced during an international workshop on capacity building at the 2021 SEFI conference. We then conducted a comparative case study, exploring similarities and differences between incentives for permanent academic staff to engage in capacity building, how capacity building is organised, and at what point in their careers staff engage in it. Our findings indicate very diverse approaches, rules and practices as well as different obstacles and challenges for engineering education. The outcomes of our study can be used by policy makers to inform capacity building practices and engineering education in HEIs (Higher Education Institutions), and our questionnaire provides a tool for monitoring and reporting practices throughout the sector.
A cross curricular comparison of professional capabilities in engineering education

Published: February 2023

In this paper we studied the student’s perception of the acquisition of professional capabilities in Challenge based learning environments with a strong reflective component. The results show students feel the relevance of personnel development from the very moment the enter their master studies. However, they only truly acquire all the relevant professional capabilities when working in interdisciplinary teams on real life problems in interaction with stakeholders.
“It’s not like it’s popular science we are doing” - Popular science, motivation, calculations, and conceptual understanding among physics and engineering students
Authors: Kjelsberg Ronny , Morten Thorseth Trond
Published: February 2023

This paper discusses the role popular science and science dissemination texts can have in learning physics in higher education for physics students and technical physics engineering students. In a mixed-methods study, students' attitudes, experienced motivation, and learning is mapped through a quantitative survey (N=155) and two qualitative surveys with in-depth interviews, one with six master level students and one with four 1st year students. The interview data shed light on two aspects of popular science's role in learning physics. Students report that reading popular science is highly motivating, but they do not have the perception of having learned physics from it. This converges with a division between calculations and conceptual understanding among the students. The paper then questions whether this gap could be closed or made smaller with greater emphasis on conceptual understanding in physics classes.
Design for impact (D4i): a framework for teaching sustainability in engineering design
Authors: Kunrath Kamila , Beliatis Michail
Published: February 2023

Sustainability has become an integrative part of engineering education since it is not possible to discuss sustainable development without also talking about innovation capability. Political and environmental frameworks request for a drastic change in the industrial landscape and also in the way design is carried out. This paradigm change forces new approaches to education that align with the prospects of the industry and also embed considerations related to the Triple Bottom Line (i.e. economic, ecological, socio-cultural elements). Addressing the complexity of sustainability requires innovative practices for teaching and learning, leading to new methodologies that aim to develop the broad sets of competencies required from the students. In Engineering Design, theories and methods related to sustainability have been mainly focused on the Design for X elements, material circularity, and product lifecycle leaving behind the importance of contextualized knowledge of regulations, or human-related aspects that motivates the students to tackle these challenges. Therefore, this study proposes a holistic approach that encompasses a broader understanding of what educators can exploit for capacitating future engineers in sustainability-related complex problemsolving. The framework highlights three main areas to be considered when teaching sustainability for Design Engineers: i) Context & Resources, ii) Human factors & Competencies, and iii) The D4i design process. A simplified version of this framework in class as a lecture-workshop format are presented and discussed along with multiple directions for future research.
