On the Energy Source of Ultrastripped Supernovae
Authors: Sawada Ryo , Kashiyama Kazumi , Suwa Yudai
Published: March 2022

Ultrastripped supernovae (USSNe) with a relatively low ejecta mass of ∼0.1 M
⊙ (e.g., iPTF 14gqr and SN 2019dge) are considered to originate from ultrastripped carbon–oxygen cores in close binary systems and are likely to be progenitors of binary neutron stars. Here we conduct the explosion simulations of ultrastripped progenitors with various masses (1.45 M
⊙ ≤ M
CO ≤ 2.0 M
⊙) based on results of neutrino-radiation hydrodynamics simulations, and consistently calculate the nucleosynthesis and the supernova light curves. We find that a USSN from a more massive progenitor has a larger ejecta mass but a smaller 56Ni mass mainly due to the fallback that leads to the light curve being dimmer and slower. By comparing the synthetic light curves with the observed ones, we show that SN 2019dge can be solely powered by 56Ni synthesized during the explosion of a progenitor with M
CO ≲ 1.6 M
⊙ while iPTF 14gqr cannot be explained by the 56Ni-powered model; ∼0.05 M
⊙ of 56Ni inferred from the light-curve fitting is argued to be difficult to synthesize for ultrastripped progenitors. We consider fallback accretion onto and rotation-powered relativistic wind from the newborn neutron star (NS) as alternative energy sources and show that iPTF 14gqr could be powered by a newborn NS with a magnetic field of B

Authors: Pozo Burgos Eduardo Javier , Burbano Pulles Marco Rubén , Vidal Chica Jack Iván , Revelo Salgado Gabriela Elizabeth
Published: March 2022

The pre-university course established at the Universidad Politécnica Estatal del Carchi (UPEC) after the disappearance of the Sistema Nacional de Nivelación y Admisión (National Equalization and Admissions System, known by its Spanish acronym as the SNNA) posed new challenges for the organizational and academic structure of this university. To start with, the challenge began with the adaptation of a curricular structure according to the educational needs of the nine undergraduate degrees offered at the university. It was followed by the implementation of the program, and finally its evaluation. The present research was designed and carried out as part of the latter goal. Its main objective was to determine the sociocultural and demographic factors that influence the academic performance of the students in the course. For the purposes of this investigation, from a methodological perspective, academic performance was associated with the number of subjects passed by the student. Using multivariate dependency techniques, a logistic regression was performed, which determined the degree of incidence of sociocultural and demographics factors on academic success. After applying the model, the results indicated that the demographic factors in this case do not influence academic success, while variables such as the educational level of the student’s parents, the student’s grade on university entrance exams and work status are significant when it comes to establishing a cause and effect relationship in this case study.

Authors: Parra-González María-Elena , Segura-Robles Adrián , Moreno-Guerrero Antonio-José , López-Belmonte Jesús
Published: March 2022

Nowadays, we talk about the use of gamification in education, an active methodology that consists of the use of mechanics, design or game structures in class. With this type of methodology, the effort is rewarded, which is treated as a motivating tool in class. There is no valid or well-structured instrument to measure gamification properly in education. This research arises from the need to develop and validate an instrument to measure the experience on gamification in educational contexts (EGAMEDU) as a useful tool of diagnosis so that the teaching staff can guide their teaching practice toward the use of this methodology. The sample used for the validation of the questionnaire is composed of 401 participants related to education and gamified experiences. The results show good validity indexes and a factorial structure according to the one proposed in the theory.

Authors: Lorber Mateja , Divjak Suzana
Published: March 2022

Hypertension is a serious medical condition, the frequency of which increases significantly with age; has a negative impact on certain health complications; and increases the rate of mortality. Music therapy as a nonpharmacological treatment has many positive effects on an individual's body and mind. A randomized controlled trial was used to evaluate the effects of music therapy on blood pressure, heart rate, and anxiety levels in older adults with hypertension living in a nursing home. Sixty older adults were randomly divided into experimental and control groups (
n
= 30 each). Significant reductions in systolic blood pressure, heart rate, and anxiety levels were found in older adults with hypertension receiving music therapy compared with the control group. The current study confirms music therapy as a safe, noninvasive, nonpharmacological, and cost-effective intervention for reducing blood pressure, heart rate, and anxiety levels in older adults with hypertension.

Authors: Ndiaye Seydou , Charahabil Mohamed M. , Diatta Malaïny
Published: March 2022

Au Sénégal, malgré l’intervention de plusieurs projets ou programmes dans l’amélioration de la productivité des plantations d’anacardiers, la filière anacarde souffre encore de nombreuses difficultés à cause des rendements faibles et les difficultés de commercialisation. Cette étude porte sur les caractéristiques des plantations d’anacardier et les déterminants des revenus en fonction de l’organisation de la filière. Les enquêtes socioéconomiques ont été réalisées auprès de 778 producteurs répartis dans soixante-trois (63) villages. Le modèle de production de Cobb Douglass qui établit la relation entre la quantité produite et le ou les facteurs de production utilisés a été utilisé pour analyser les déterminants des revenus issus de vente des noix par les producteurs. Les résultats obtenus ont montré que la superficie moyenne d’une plantation est en moyenne de 2,5 ha (dans le département de Ziguinchor), 3,7 ha (Sédhiou) et 2,1 ha (Kolda). Le nombre de pieds d’anacarde/ha est estimé à 167 pieds/ha pour la région de Ziguinchor, 198 pieds/ha pour celle de Sédhiou et 187 pieds/ha à Kolda. La région de Ziguinchor est la plus productive (385 kg/ha), suivi de Sédhiou (280 kg/ha) et Kolda (255 kg/ha). Les revenus des producteurs connaissent une amélioration significative avec une bonne production, d’un prix de vente du kilogramme de noix est supérieur à 500 FCFA, mais également avec un meilleur accompagnement des producteurs. En revanche, les facteurs tels que le paiement de la main-d’œuvre pour la collecte et l’entretien des vergers a une influence négative sur les revenus des producteurs. La filière anacarde occupe une place importante de l’économie de la zone agroécologique étudiée. Elle contribue significativement à l’amélioration des conditions socioéconomiques des producteurs. Toutefois, une structuration du maillon commercialisation permettrait aux producteurs de mieux tirer profit de la vente des noix de cajou.

Authors: Atici Uğur , Gürcan Ömer Faruk , Güldeş Meral , Şahin Cenk
Published: March 2022

Renewable energy sources are clean energy sources and have a much lower environmental impact than other energy sources. Energy production from biomass allows the storage of energy raw materials, unlike other renewable energy sources. Some factors and criteria affect the site selection of biomass power plants. Determining the significant levels of these conflicting criteria is vital for investors in choosing a biomass power generation facility location. Location selection of biomass power plants is a multi-criteria decision problem for decision makers. The relative importance of the criteria includes quantitative evaluations and is an uncertain process. In this study, a comprehensive literature study determined the criteria to be considered in selecting biomass energy production facility locations. The fuzzy analytical hierarchy process was used to determine the importance levels of the criteria to be used to select the bio-mass power plant establishment location.
Evaluation of the Criteria Used in the Selection of Renewable Energy Sources With the Plithogenic PIPRECIA Method
Authors: Ulutaş Alptekin , Topal Ayşe
Published: March 2022

The use of fossil fuels has decreased compared to the past due to the gradual depletion of fossil fuels and the greenhouse gases emerging in their use. As a result of this decrease, many countries have turned to alternative energy sources instead of fossil fuels. The most popular energy sources among these alternatives are renewable energy sources. Compared to fossil fuels, renewable energy sources cause little or no harm to nature. While renewable energy sources differ according to the countries, it is necessary to determine the most optimal renewable energy source for countries. In the literature, the most optimal renewable energy source selection has been made many times, and while this selection is made, multi-criteria decision-making (MCDM) methods are generally used. In these studies, the most optimal renewable energy source was selected by considering multiple criteria. In this chapter, criteria that are frequently used in the literature will be evaluated with the Plithogenic PIPRECIA method. In addition, the most important criterion will be determined.

Published: March 2022

During the dissertation journey, graduate students must expect to receive critical feedback. And, yet, in order for this critical feedback to be productive, graduate students must be able to perceive this feedback as helpful rather than as discouraging. This chapter explores the interpretation of critical feedback through the cognitive framework of attributional style. This chapter presents six anecdotes and six reflections as recounted by six graduate students. By presenting these authentic examples, this chapter demonstrates how reflecting on attributional style can assist graduate students in reappraising the critical feedback they receive throughout their dissertation journey.
An Integral Theory Approach to the Feedback System in Supervising Doctoral Students in the Nordic Higher Education Context
Authors: Cordeiro Cheryl Marie
Published: March 2022

Feedback giving makes an important part in the context of higher education thesis writing, in particular, doctoral thesis writing supervision. In the past decade, European level standardization higher education policies have encouraged a pedagogy paradigm shift towards a more student-centered learning approach. Within the Nordic context of higher education, feedback giving from supervisor to student has often been studied from the perspective of the supervisor, as a small part of the overall doctoral degree program. This study uses findings from foundational pedagogy literature in the field of Nordic pedagogy studies in combination with empirical data findings from interviews, and maps elements of the doctoral thesis writing feedback system from an integral pluralism approach. The integral model of a feedback system to a doctoral thesis supervision is novel for the Nordic pedagogy literature and it is meant as complement to the current canon of literature on Nordic pedagogy.

Minding the Gap
Authors: Abila Sanley S.
Published: March 2022

This chapter examines how a nation-state and the global maritime industry can be seen promoting seafarers' mental health by integrating mental health to the standards of maritime education. Mental health promotion refers to multi-level strategies that aim to produce positive contributions to mental health such as through formal education for workers operating in highly stressful work environments such as seafarers. Examining studies on mental health of seafarers, evidence shows that promoting mental health of seafarers through education might be needed to help seafarers due to poor mental health outcomes when working as a seafarer. The promotion of mental health through education of seafarers is anchored to the potential of integrating human rights and human rights law to maritime standards. By doing this, this chapter aims to contribute to the promotion of mental health in seafaring as well as to initiatives integrating human rights law to maritime standards.

Authors: Datta Hrijuta , Singha Roy Moutoshi
Published: March 2022

Studies involving applications of mechanics in the biological systems to understand different physiological processes date back to ancient times. The development of the subject gained momentum in the medieval and renaissance periods by different stalwarts in the field of science, like Galileo, da Vinci, von Helmholtz, to name a few. However, it is not very long ago that the computational approach was recognized and accepted as the potentially important avenue for exploring biomechanical phenomena. However, as the computers became more and more powerful, it was possible for the scientists and engineers to simulate more complex phenomena having complex three-dimensional geometries, dynamically changing loading conditions, and interaction between multiple phases, including fluid-solid interactions. This chapter gives a detailed description of the evolution of different computational approaches in the field of biomechanics, along with their comparative benefits and shortcomings from a historical perspective with future directions in the research.

Authors: Dhason Raja , Roy Sandipan , Datta Shubhabrata
Published: March 2022

After total hip arthroplasty (THA), high demands occur in the femoral fixation, especially for elderly patients due to periprosthetic fractures. Fractures happened in the femur after THA was classified based on Vancouver periprosthetic femoral fracture. Choosing the fixation for these types of specific fracture types are challenging due to pattern and orientation of the fracture in the THA prosthesis. Several researchers have reported the clinical, experimental, and computational studies about the failure of fixation methods, and they highlighted the remedies and scope in the further studies. Most of the authors recommended the computational studies having the advantage to predict the inner behaviour of the bone because invivo/invitro study availability of the specimen are limited and it needs ethical clearance. The current study focussed on computational studies in periprosthetic fractures and aims to discuss the three dimensional model creation, mesh generation, material properties, boundary conditions/loading, limitation, opinions, and future thoughts in implant design.

Tunable Attenuator Based on Hybrid Metal-Graphene Structure on Spoof Surface Plasmon Polaritons Waveguide
Authors: Hlali Aymen , Zairi Hassen
Published: March 2022

A novel type of tunable attenuator on spoof surface plasmon polaritons (SSPP) waveguide based on hybrid metal-graphene structure for terahertz applications is proposed in this chapter. Two structures are analyzed and designed, where the first is composed of a graphene sheet at only one cell of the SSPP waveguide and the second at all cells. By varying the graphene chemical potential via a biased voltage, the surface conductivity of graphene can be adjusted. Therefore, the attenuation can also be adjusted. Moreover, an equivalent circuit model is proposed to facilitate the designs of the proposed attenuator and offer the general understanding of the attenuation mechanism. Numerical simulation results with the CST simulator and WCIP method have a good agreement with the theoretical results. The simulated results show that the attenuator can obtain adjustment range from 6.02 to 14.32 dB for the first structure and from 1.58 to 30.93 dB for the second, as the chemical potential rises from 0 to 0.5 eV.

The programme, developed in 2017, is a response to Ireland's National Access Plan (2015-2019) and a growing awareness for the need to diversify the teaching profession in Ireland and is funded by the Higher Education Authority (HEA). The data gives voice to traveller students who participated in the TOBAR programme and will provide unique insights that balance the majoritarian narrative on access and inclusion. Drawing on a series of semi-structured interviews with three students on the TOBAR programme, the authors report that while the programme is having a positive impact on accessing higher education, challenges at student level and at HEI level still exist.
First-Year College Students Connect With Citizens Returning From Incarceration Through Mindfulness
Authors: Zaccarini Maria Cristina
Published: March 2022

This chapter describes the ongoing work of the author, Professor Maria Cristina Zaccarini, of Adelphi University, and Network Support Services, a reentry organization based in New York. Students in Professor Zaccarini's class learn the koru method of mindfulness, and alumni of Network Support Services learn mindfulness while in prison and during their time of reentry as returning citizens. Students examine the works of mindful historical figures who are significant for the understanding of the links among economic, social, and other disadvantages and incarceration. Students interview network alumni and write 500-word essays with the aim of explaining the experiences of the alumni and then reflect on how these exercises shaped their understanding of mindfulness. Student work makes public the firsthand accounts of the network alumni, as it is published on the web.
Inclusion and Accessibility for Students With Disabilities in Higher Education
Authors: Dyer Rebekah Dawn
Published: March 2022

Diversity is defined as the range of human differences. When considering diversity, it is important to include individuals with disabilities in the dialogue. There is not a single campus that is not impacted by disability. This population is often overlooked regardless of their specific needs and rights under the law. Each of the disability categories is a range within itself. No two individuals with the same disability are the same, as they are diverse within their commonality. Research indicates a lack of recognition of disability as an identity group in higher education. Disability is often not recognized in diversity and inclusion efforts. We are missing a large part of the diversity conversation when disability is not included. Higher education institutions must consider the diverse needs of individuals with disabilities to provide the appropriate supports, promote inclusion, and ensure the students can be successful. The intersections between race, ethnicity, and disability are a critical part of the diversity conversation.
Diversity and Racism in Higher Education

This chapter explores racism in university and its detrimental impact on students and staff of colour in the UK. The authors propose The Six Stages Framework as an effective assessment tool to assist individuals in their journey to understanding and challenging racism. With this, it is hoped that individuals can tackle cultures of racism perpetuated by implicit biases. A case study analysis explores the lived experience of racism within a UK university. This sheds light on the devastating impact of lack of diversity, cognitive dissonance, and racist cultures among university staff, systems, and students. This case study demonstrates the usefulness of The Six Stages Framework in framing the causes of racist behaviour and as a communication tool to explain why racial abuse may take place.

This research studied the preparation of luminescent glasses using 18SiO2-35B2O3-22ZnO-20K2O glass frits. The glass frits were first mixed with 15 wt.% of commercial SrAl2O4:Eu2+,Dy3+ phosphors and different B2O3 concentrations of 0-15 wt.%. The raw materials were then melted at 750-800°C for 1 hr. The results showed that the addition of B2O3 as a flux induced the crystallization of α-Zn2SiO4 phase and suppressed the luminescent properties of phosphor-in-glasses. This could be due to the dissociation of SrAl2O4 by the reaction of SrAl2O4 and B2O3. The higher sintering temperature at 800°C also further degraded the luminescent properties as a result of further phosphor degradation and the oxidation of Eu2+.

Natural rubber latex (NRL) with the deproteinized process was interesting for cosmetic and transdermal drug delivery systems because of its notable characteristics. The purpose of this study was to develop in situ cooling films from deproteinized natural rubber latex (DNRL). Menthol, camphor, and volatile oils were added into DNRL emulsions for cooling effect and pain relief. The pH, rheological properties, particle size, and zeta potential of emulsions were examined. Then, the time of film-formation, morphology, and mechanical properties of the cooling NRL films were evaluated. The resultant emulsions revealed that their pH was about 5.7 - 6.3. The viscosity was in the range of 1000 – 3000 cps and indicated the pseudoplastic flow. The increasing amount of olive oil reduced the particle size and increased the negatively zeta potential of those emulsions. The film formation time of specimens was about 4.5 - 6.5 mins. The cooling films demonstrated smoothness and homogeneity. The presence of olive oil increased the softness of films. The increasing of oil volume increased the elasticity; however, it decreased the ductility of the films. This in situ cooling DNRL film was also effective forward for the development of a transdermal drug delivery system.

Several biomaterial presented anticancer activities including volatile oil. Interestingly, the volatile oil from Amomum kravanh has been reported as anticancer activity. Nevertheless, the utilization in native oil might be barrier to apply its as anticancer agent because of the limitation of their water solubility. One of the solutions to this challenge is to use nanoemulsions as a carrier for delivery A.kravanh oil (AMO) into oral cancer cell. In this research, the phase inversion temperature method was used to prepared nanoemulsions containning AMO. The physical and anticancer property of various nanoemulsions were comparatively evaluated. The 8AMO:2Soybean oil (SBO) illustrated spherical and small oil droplet around 80 nm. It also presented good physical stability after temperature cycling test. Regarding anticancer property, the 8AMO:2SBO can considerably arrest oral cancer cells with dose dependent manner at IC50 of 0.76% v/v, and the nuclear fragmentation that was remarkable feature of apoptosis was also found in 8AMO:2SBO group. This discovery demonstrated that the AMO loaded nanoemulsions system can be consider to alternative choices for oral cancer prevention and treatment.

Senna alata leaf is used as an active ingredient in various Ayurvedic preparations due to its bioactive components. This study examined the effect of extracting solvents on total phenolic and rhein contents as well as antioxidant and anti-inflammatory capacities in S. alata leaf extracts. 95% v/v and 50% v/v ethanol (EtOH) solutions were used as extracting solvents. In spite of its lower extraction yield, 95% EtOH extract with a lower moisture content should be considered more microbiologically stable than 50% EtOH extract. As a result of the analysis using thin-layer chromatography (TLC), Fourier-transform infrared (FTIR) spectrophotometry, and high performance liquid chromatographic diode array (HPLC-DAD), phytochemicals including anthrones, coumarins, and anthraquinones were found in both extracts. Additionally, the 95% EtOH extract possessed higher phytochemical contents and biological activities than the 50% EtOH extract. Thus, the 95% v/v EtOH was a powerful extracting solvent for preparation of S. alata leaf extractscontaining high contents of phenolics and rhein, together with antioxidant and anti-inflammatory activities.
