Limited water availability is one of the important abiotic factor affecting yield of wheat crop. Exogenous application of osmolytes is an important factor in reducing the stress due to water shortage. Keeping in view the role of proline and L-tryptophan (L-TRP) in stress alleviation, a study was carried out at the agricultural research area of the University College of Agriculture and Environmental Sciences, The Islamia University of Bahawalpur, Pakistan, during winter 2015-2016 to evaluate the impact of foliar applied proline and L-TRP on growth and photosynthetic efficiency of wheat grown under limited moisture supply. Drought stress was applied in three levels (I1 = control, I2  = drought stress at tillering stage and  I3 = drought stress at grain filling stage) while, foliar application of proline and L-TRP was done in six levels [T1 = control; T2 = proline (10 mM); T3 = proline (20 mM); T4 = L-TRP (10-4 M); T5 = L-TRP  (10-4 M) + proline (10 mM) and T6 = L-TRP (10-4 M) + proline (20 mM)]. The experimental results revealed that growth and photosynthetic efficiency of wheat were decreased due to reduced water supply. However, exogenously applied proline and L-TRP considerably ameliorated the effect of drought stress. Combined application of L-TRP (10-4 M) and proline (20 mM ) showed better results and induced tolerance to drought stress, in comparison with other treatments. Foliar application of proline and L-TRP also enhanced the photosynthetic rate which might be related with the improved photosynthetic pigments. Overall, exogenously applied proline and L-TRP mitigated the adverse effects of moisture deficit on growth and photosynthetic efficiency of wheat crop.

Published: May 2021

Active metabolites of methanol, ethanol, ethyl acetate and aqueous extracts of the leaves of Andrographis paniculata were identified using thin layer chromatography and gas chromatography-mass spectrometry (GC-MS). Results from this study identified some of active metabolites as andrographolide, 14-deoxyandrographolide, neoandrographolide, 14-deoxy-11,12-di-dehydroandrographolide, andrographanin, isoandrographolide, 14-acetylandrographolide, 19-0-andrographolide, beta-sitosterol and 14-deoxy-14,15- dihydroandrographolide. Ethanol was a more effective solvent for the extraction as most of the phytochemicals were identified in this extract. Research had shown that extracts from the leaves of the plant possess a lot of therapeutic properties such as anti-microbial, anti-inflammatory, anti-diabetic, immune modulatory and antimalarial activities which are of immense benefit to man.

Greening the Gulf - Coastal Restoration using Mussels

A hundred years ago the Hauraki Gulf was home to probably the largest single mussel population in the world - over 500 square kilometres of seabed. Over a period of 60 years Aucklanders and their neighbours ate their way through these mussels, leaving nothing but desolate muddy seafloor behind. Since the fishing stopped in the 1980s the mussels have not shown any sign of recovering at all. Recently, the community group, Revive Our Gulf, has been working with researchers at the University of Auckland in an ambitious project to restore mussel beds to the Hauraki Gulf. This presentation will describe the history, the challenge of what is involved and the progress to date.

Authors: O'Brien Dr. Benjamin
Published: May 2021

Dr Ben O’Brien joined the ABI in 2007 as part of Professor Iain Anderson’s Biomimetics Lab, where he also met fellow PhD student (now Dr) Todd Gisby and they had an unreasonable amount of fun making things out of artificial muscles. In 2012 the three co-founded StretchSense to bring an entirely new type of stretchable sensor to market. Today, StretchSense is the clear market leader for stretchable motion capture gloves for the gaming and animation industry. Ben will talk about the winding journey from there to here as well as the challenges and successes along the way and the experiences bringing deep tech products to market. Ben will bring a live demo of our MocapPro Supersplay glove and software Hand Engine, which are awesome. The talk will start as a presentation but will hopefully degenerate into a conversation, or even better, a debate.

Погребальный комплекс эпохи бронзы урочища Тесик
Authors: Горячев Александр Анатольевич , Потапов Станислав Александрович , Чернов Михаил Алексеевич
Published: May 2021

В статье систематизированы результаты исследований погребального комплекса могильника эпохи бронзы Тесик-I одноименного урочища в горах Айтау. Комплекс состоит из 56 разнотипных и разновременных в пределах эпохи бронзы сооружений в виде курганов и оград прямоугольной, квадратной и округлой форм. Основные виды погребальных камер представлены каменными ящиками и цистами. Исследования погребального комплекса эпохи бронзы урочища Тесикпроизводились на основе выработанных ранее для региона методов археологической разведки и раскопок.В центральный части могильника Тесик-I исследована конструкция цепочки каменных оград размерами ~ 14×5,8 м, где расчищено шесть погребальных сооружений в виде каменных ящиков. Все крупные могильные конструкции по характеру иформе сооружения напоминают «бесик», что, вероятно, связано с религиозными представлениями древнего населения о Смерти как акте перерождения в ином загробном мире. Умерших хоронили в скорченном виде на левом боку головой назапад. Как правило в изголовье устанавливалась керамическая посуда (от одного до трех сосудов). Вещевой инвентарь (изделия из глины и бронзы), фиксируемые среди костных останков внутри могил, являлись деталями и украшениями погребальнойодежды и маркировали их социальный статус. К особенностям погребальной практики всех захоронений комплекса следует отнести помещение в могилу «порченной» посуды.Исследованный комплекс, датируемый в пределах XVI–XV вв. до н.э., представляет смешанные алакульско-федоровские погребальные традиции андроновского периода эпохи бронзы Шу-Илейского региона. Развитие древней культуры во взаимодействии с населением Центрального Казахстана сформировало круг погребальных комплексов Шу-Илейского междуречья, имеющих существенные отличия от памятников других районов Жетысу в горах Джунгарского (Жетысу) иЗаилийского (Иле) Алатау. Перспектива дальнейших исследований связана с изучением всей структуры погребальных комплексов Шу-Илейского междуречья и степени социально-экономических и этнокультурных взаимосвязей древнего населения с соседними регионами.

Celebrated Master Artists of the Bikaner School
Authors: Davis Shanane
Published: May 2021

In this article I have tried to incorporate details about Shah Muhammed, the first celebrated artist of the Bikaner School. During the last decades of the 16th Century, he was trying to achieve a new style by mixing various school styles and techniques. He started to paint in Bikaner and paintings attributed to him were found up to the beginning of the 17th Century. Nur Muhammed learned the fundamentals of "Siyah Kalam on Warqa", painting, and various school styles from his uncle Shah Muhammed. A review of Shah Muhammed's "Siyah Kalam on Warqa" shows his focus was more on the practice and application of various influences and fusions of styles.
Grapevine communication

Published: May 2021

Communication is a constant part of Teaching Learning Process. The act of transferring information from one place, person or group to another is called communication. People who lie in the top hierarchy usually control formal channel of communication. Communication basically travels through informal channels, called “the grapevine.” Basically the term grapevine communication originated during early Civil War days when the telegraph wires strung through the trees and resembled like grapevines. It is observed that nowadays the grapevine means “the informal transmission of information, gossip or rumour spread from person to person.” As this mode of communication is informal, all information that passes through is open to change and interpretation can vary time to time. The well evident facts provide proofs that grapevine gives an outlet for imagination and truth seeking. Grapevine effect can be used to manage sharing of information amongst one another in an unofficial, or informal, manner. In this article an attempt is made to explain each and every dimension of grapevine communication i.e. Single Strand Chain, Gossip Chain, Probability Chain and Cluster Chain along with that advantages, disadvantages and significance of grapevine communication.
Inhibition of Macrophage Migration Inhibitory Factor Reduces Endometriotic Implant Size in Mice with Experimentally Induced Disease
Authors: Nothnick Warren B. , Colvin Arlene , Cheng Kai Fan , Al-Abed Yousef
Published: May 2021

Aim

Macrophage migration inhibitory factor (MIF) is a cytokine whose expression is elevated in endometriotic tissue from women with the disease but the functional role of this factor in the pathogenesis of the disease is uncertain. The objective of the current study was to examine the role of MIF in the pathogenesis of endometriosis.

Method

Experimental endometriosis was induced in mice and the ability of the MIF antagonist, ISO-1, to reduce endometriotic implant size was assessed.

Results

Administration of ISO-1 resulted in a significant reduction in implant size and vascularity (as assessed by Flk1 mRNA expression) which was not associated with an alteration in the reproductive cycle.

Conclusion

These data suggest that inhibition of MIF activity is associated with a significant reduction in endometriotic implant size and leads us to speculate that a similar approach of targeting MIF may prove useful in treating endometriosis in humans.
"Treat everybody right": Examining foodways to improve food access
Authors: Hill Alex
Published: May 2021

Detroit is regularly assumed to be a “food desert” despite contradicting evidence. With fruits and vegetables available at each of Detroit’s 70 independent, full-line grocery stores, there remains a lack of understanding among media and academics of residents’ perception and preferences for food access. A baseline study was initiated during the summer of 2014 to understand residents’ own perceptions of food access and to assess the socio-cultural foodways utilized by residents. A total of 207 Detroit residents participated in focus groups and interviews to discuss food provisioning. Residents identified a wide range of food access points, from home gardens and fishing to specialty meat markets and big-box stores. However, 60% of residents reported that their primary grocery store was a chain supermarket outside the city limits. Residents highlighted “customer service” and in-store treatment as key factors in choosing where to shop for food. These new findings present contradictions to assumptions about food access in Detroit and similar cities. The findings point to a significant opportunity to leverage geo-ethnographic methods in order to focus on resident perceptions and preferences to improve food access.

Published: May 2021

Background and objective: Oncology nursing is a recognized nursing specialty globally but it is yet to be a stand-alone specialty in any accredited degree awarding tertiary institution in Nigeria as at the time of this write up. In most of the hospitals in Nigeria, non-specialist oncology nurses who learn on the job care for the cancer patients. Hence, the urgent need to conduct this study. The aim of this study was to study the state of oncology nursing training and practice in Nigeria.Methods: A descriptive, cross-sectional study was used to assess 171 nurses’ socio-demographic data, nature of their oncology training, and competency level using a semi-structured questionnaire.Results: Only 3 (1.8%) of the respondents claimed they had a degree in oncology nursing and 89.9% had no formal training in oncology. Few of the respondents (13.5%) rated themselves as experts in oncology nursing practise. Majority of the respondents see the state of oncology nursing practise as very poor with the major challenge being none availability of oncology nursing training institution.Conclusions and implication for study: With the increasing incidence of cancer in Nigeria and rise in number of new cases daily, there is need for an established programme to train health care professionals especially nurses to combat its increasing rate. There is need for provision of oncology nurse specialist training to improve level of education and skills in order to offer appropriate care to clients living with cancer and improve patient’s outcome of survival ultimately enhancing their quality of life.

Authors: SAHIN Selin , BESİR Ahmet , AKDOGAN Ali , TUGCUGIL Ersagun , SAYLAN Sedat
Published: May 2021

Objective: We compared the air or saline insufflated endotracheal tube (ETT) cuff pressures and their effects on postoperative
respiratory complications in gynecological laparoscopic surgeries in the Trendelenburg position (TP).
Patients and Methods: This prospective study was carried out on a total of 60 patients, whose ages ranged from 18 to 65 years and
who were classified by the American Society of Anesthesiologists (ASA) as I-III. They were scheduled for gynecological laparoscopic
surgery in TP. Patients included in the study were randomly divided into two groups as the saline (Group S, n=30) and air (Group A,
n=30) groups. ETT cuff pressures and peak airway pressures were recorded immediately after intubation and at 10-minute intervals
during the intraoperative period.
Results: The cuff pressure and maximum cuff pressure values in the saline group were significantly lower than in the air group in
the 50-minute (p<0.05). The sore throat and analgesic consumption were significantly lower in Group S in postoperative 24 hours
(p<0.001, for all).
Conclusion: The intraoperative cuff pressures, postoperative sore throat, and analgesic consumption were lower in the salineinsufflated
group than in the air-insufflated group in gynecological laparoscopic surgery in TP.
The Conflict between Adonijah and Solomon in Light of Succession Practices Near and Far
Authors: Knapp Andrew
Published: May 2021

The protocols for succession to the throne in ancient Israel and Judah have attracted little scholarly attention. In this article I first survey monarchic societies throughout history to show that there are no universally valid succession principles, despite scholars often treating primogeniture as such. I then look at evidence from ancient Near Eastern societies and suggest that in a “standard” scenario the incumbent king was expected to select a successor from a pool of viable candidates. I conclude by rereading Solomon’s accession to David’s throne in 1 Kings 1-2 in light of this.
The GRADE approach, Part 2: Evidence to decision frameworks—outlining decision-making in health
Authors: Quilodrán Carlos , Kirmayr Matías , Valente Bárbara , Pérez-Bracchiglione Javier , Garegnani Luis , Ariel Franco Juan Víctor
Published: May 2021

The GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology provides a framework for assessing the certainty of the evidence and making recommendations. The Evidence to Decision Framework (EtD) is a transparent and structured system for formulating health recommendations. Once the problem is identified and the certainty of the evidence is assessed, EtD provides several criteria for formulating a recommendation. These criteria include the trade-off between benefits and harms, patients’ values and preferences, acceptability, feasibility, resource use, and impact on equity. The resulting recommendations may differ in strength (strong or weak) and direction (for or against). The process is transparent, allowing other users to adjust the framework of recommendations by modifying the criteria to fit the desired context through an adaptation-adoption process. Given the extensive information available on EtD and the GRADE methodology in general, this narrative review seeks to explain the main concepts involved in decision-making in health by using simplified and friendly descriptions, accompanied by practical examples, thus facilitating its understanding by inexperienced readers.
Blood pressure and high altitude: physiological response and clinical management
Authors: Lang Morin , Bilo Grzegorz , Caravita Sergio , Parati Gianfranco
Published: May 2021

High altitude is an extreme environment that challenges human beings exposed because of work, recreational activities, or habitat. Exposure to hypobaric hypoxia results in physiological adaptations in response to the geography and the associated extreme environmental conditions. These acclimatization responses can be diverse and result from evolutionary changes and comorbidities. In this context, this review aims to identify the available evidence on the effects of high altitude on blood pressure—from the physiological to clinical aspects at rest and during exercise—and the underlying mechanisms and possible clinical implications of acute and chronic intermittent hypoxia.
The educationalization of school architecture in Switzerland between 1840 and 1950
Authors: Helfenberger Marianne
Published: May 2021

This paper analyses and contrasts the evolution of school architecture competitions, selected submitted projects and built schoolhouses, programmatic and professional literature, school building exhibitions and public reactions to them aiming at answering the following research question: How did architecture competitions, educational reforms and programmatic or professional literature contribute to the educationalization of the school building between 1835 and 1950 in Switzerland? The question will be approached from a perspective of educationalization, knowledge transfer and circulation between professional and political knowledge or discourses on education and practices of architecture competitions by contextualizing school building reform discourses within general school and education reform processes. The evolution of school building architecture competitions in Switzerland and the participation of a variety of actors demonstrate how the school building became a co-educator, how historical building designs are constantly naturalised to fit reform programs, and the relevance of calls for tender as source for the history of education.
Mujeres pioneras: la catedrática de instituto Rosario Fuentes
Authors: Fernàndez Gonzàlez Jorge
Published: May 2021

If higher education was already restricted and off-limits to women until the 20th century, their access to teaching and obtaining academic positions  at these levels was even more difficult and complex. The aim of this paper is to describe a paradigmatic case of this problem: the life of Rosario Fuentes, who achieved the highest score in a public exam to become French professor and who became the first secondary school professor at the Zorrilla high school in Valladolid. Fuentes alsohad a relevant career as a translator, with contributions to texts on education, philosophy and psychology. This study highlights her role as a researcher associated with the Junta para la Ampliación de Estudios (Board for Advanced Studies) and as a writer of French textbooks. She also took part in the organization of language teachers as well as teaching in different Teacher Training Schools. Her career suffered as a result of the purging process which Franco’s dictatorship carried out on teachers, a process that was especially arbitrary against women due to the fact that their own actions and thoughts were often considered less relevant than those of their partners or relatives.. This paper, which examines many of these aspects of her life, relies on documentation and unpublished images from different archives such as those of the administration and the family, as well as previous works that analyse the issue of women teachers in Secondary Education.
Gentes igual que tú y que yo: los textos de Rosario Castellanos en los contrasentidos ideológicos de la política lingüística indigenista
Authors: Ayala Reyes Susana
Published: May 2021

In this article we analyze documents written by Rosario Castellanos during the years that she worked as a scriptwriter for the puppet plays in the Highlands of Chiapas. These plays were part of educational campaigns aimed at the Tsotsil and Tseltal Maya population. We show that the discourses  circulating during the years in which indigenous politics was being  constructed were permeated by opposing and contradictory ideological tensions, tensions that were reflected in the proposal and use of categories of identification of the population and their languages, in the theoretical objectives and ideals and in the participants’ personal and collective stories.

Crisis” and “re-foundation” of psychology – outmoded topics of theoretical-psychological discourse?
Authors: Maiers Wolfgang
Published: May 2021

In the 1970-80ies critical assessments of the problematic state of psychology as science were flourishing, stressing the theoretical disintegration and practical irrelevance of psychological basic research and connecting both defects to a misplaced dependence of mainstream psychology on a scientistic notion of scientific cognition. Talks of a crisis in psychology were gaining ground again. Controverting the paradigmatic maturity vs. the pre-/non-paradigmatic state of our discipline or, alternatively, its necessarily multi-paradigmatic character, the quest for unification as against a programmatic theoretical pluralism became a top issue of scholarly dispute. The institutionalisation of ISTP in 1985 and its initial epistemological and meta-theoretical core themes clearly reflected this pervasive trend. Some 35 years later, it has become noticeably quiet about such concerns, and there is no evidence of a renewal of large-scale discussions on a foundational crisis in psychology, let alone of ambitious attempts at theoretical unification or re-foundation – despite the fact that none of the “epistemopathologial“ (Koch, 1981) diagnoses of traditional variable-psychology have been refuted or lost strategic importance. Combining historical retrospection with an exemplary analysis of topical theoretical-psychological subjects, the aim of my paper is to get a clearer idea of where Theoretical Psychology currently stands in regard to the meta-scientific study of psychological theory-problems.
On the Aesthetics of Self Expression:
Authors: Cresswell Jim
Published: May 2021

Theoretical psychology is at its best when it engages in the wider psychological community by bringing about critical reflection and synthesis. This vision is challenging to accomplish due to “anesthesia”: a practice of ‘comatose’ production divorced from authentically generative activity and meaningful engagement with others. This notion is developed by drawing on Marcuse’s discussion of the surplus of suppression enabled by technology and a hyperreal milieu. Technological practices such as the engineering of social media platforms maximize anesthesia and amplify such concerns. I advocate for a turn to Bakhtinian aesthetics of self-expression to spell out an aesthetic for theoretical psychology.
Young people’s sharing of sexualized digital imagery
Authors: Rasmussen Penille Kærsmose Bøegh , Mandau Morten Birk Hansen
Published: May 2021

The ubiquity of smartphones and social media has introduced new ways of being connected and engaged in digitally mediated spaces, including the possibilities of exchanging private sexualized digital imagery – a practice known as ‘sexting’. In this paper, we study the ways in which young people’s engagement in both consensual and non-consensual sexting practices is facilitated – and sometimes even accelerated – by technology. Our study is based on focus group interviews with young people aged 16-21, 6 months of digital ethnography on social and digital media, and posts concerning sexting written by young people on Danish counselling websites. We draw on perspectives from postphenomenology and new materialism in order to focus on human-technology interactions and how digital technologies shape social processes and interactions when young people exchange sexualized digital images and videos. We attend to the ways the affordances of social media (e.g., spreadability, ephemerality and persistence) facilitate and mediate young people’s sharing of sexualized imagery and how the affects emerging through these processes produce intensities, fantasies and intimacies, which both motivate and accelerate these practices. Our analyses seek to refine current understandings of young people’s production and sharing of sexualized digital imagery. Moreover, we argue that there is a need for further development of psychological concepts and analyses that can adequately grasp the nuances of the complex digital and visual intimate, social, sexual processes of young people’s lives and advance the research field of sexting among young people.
Selected aspects of the transformation of agriculture in the CEECs following the fall of the Eastern Bloc
Authors: Bański Jerzy
Published: May 2021

Over the last three decades, agriculture in Central and Eastern Europe has undergone very profound change. This first and foremost reflected the collapse of the communist system, as well as accession to the European Union in the case of most of the CEECs. The work detailed here has thus had as its cognitive goal the identification of trends regarding selected components of agriculture’s spatial structure which have included agrarian structure, agricultural land use, and the structure of agricultural production. Attention has also been paid to what conditioned the transformation, as well as the spatial differences that characterised it. With a view to these objectives being achieved, 11 current EU Member States in the region were analysed, above all by reference to source materials from EUROSTAT and the FAO.
Observation des comportements agressifs des patients hospitalisés : entre devoir d’identification précoce de l’agressivité, risques de stigmatisation et exigences thérapeutiques
Authors: Kaision Jean-Michel , Camus Didier , Cossy Yves
Published: May 2021

L’absence d’une définition claire de la dangerosité et de la violence en psychiatrie, ainsi que le constat d’échec général des outils de prédiction ne doivent pas interrompre le développement du management des risques dans l’institution. Nous proposons l’utilisation d’une échelle d’observation des comportements agressifs qui s’inspire largement du modèle de l’OAS (Overt Agression Scale ) développée par Yudofsky et ses collaborateurs. Il s’agit d’améliorer la qualité de l’observation infirmière et, ce faisant, d’utiliser l’OAS comme un médium pluridisciplinaire d’une part, et comme outil de communication avec le patient concerné, d’autre part. Entre banalisation et stigmatisation, nous restons attentifs au besoin de sécurité du personnel soignant et aux risques d’exclusion des patients « dérangeants ».
Jardiner pour l’oeil et pour l’oreille : le destin musical de la Théorie de l’art des jardins (1779–1785) de C. C. L. Hirschfeld1
Authors: Morasse-Choquette Étienne
Published: May 2021

Vers la fin du 18e siècle, la question du rôle des sens dans l’expérience esthétique que procure l’art des jardins fit débat. Alors que certains auteurs se montrèrent réticents à l’idée d’accorder une valeur esthétique à tout autre sens que la vue dans un jardin, C. C. L. Hirschfeld fut l’un des premiers théoriciens à s’intéresser à la nature intersensorielle de cet art. Cet article examine plus spécifiquement la place de l’ouïe dans sa célèbre Théorie de l’art des jardins (1779–1785).
Beyond Anti-Conquest: Unearthing the Botanical Archive with Locative Media
Authors: Didur Jill
Published: May 2021

This article introduces the Alpine Garden MisGuide / Le Jardin alpin autrement, a locative media project that endeavours to bring the complex cultural and historical insights of the paper archive on botanical exploration into dialogue with the embodied experience of visiting the living archive of contemporary botanic gardens. Recently created mobile guides to botanic gardens tend to fall back on the discourse of “anti-conquest”—where the colonial subject claims innocence even as s/he subordinates the other to their gaze—to frame their collections for the public. Taking a decolonial approach, this essay explores how the affordances of the MisGuide’s locative platform presents opportunities to challenge innocent or nostalgic presentations of botanic gardens’ collections and engage garden visitors in a more complex account of the influence of colonialism in the history of gardens and the environment.

A fast region-based active contour for non-rigid object tracking and its shape retrieval
Authors: Mewada Hiren , Al-Asad Jawad F. , Patel Amit , Chaudhari Jitendra , Mahant Keyur , Vala Alpesh
Published: May 2021

Conventional tracking approaches track objects using a rectangle bounding box. Gait, gesture and many medical analyses require non-rigid shape extraction. A non-rigid object tracking is more difficult because it needs more accurate object shape and background separation in contrast to rigid bounding boxes. Active contour plays a vital role in the retrieval of image shape. However, the large computation time involved in contour tracing makes its use challenging in video processing. This paper proposes a new formation of the region-based active contour model (ACM) using a mean-shift tracker for video object tracking and its shape retrieval. The removal of re-initialization and fast deformation of the contour is proposed to retrieve the shape of the desired object. A contour model is further modified using a mean-shift tracker to track and retrieve shape simultaneously. The experimental results and their comparative analysis concludes that the proposed contour-based tracking succeed to track and retrieve the shape of the object with 71.86% accuracy. The contour-based mean-shift tracker resolves the scale-orientation selection problem in non-rigid object tracking, and resolves the weakness of the erroneous localization of the object in the frame by the tracker.
An optimized transfer learning-based approach for automatic diagnosis of COVID-19 from chest x-ray images

Published: May 2021

Accurate and fast detection of COVID-19 patients is crucial to control this pandemic. Due to the scarcity of COVID-19 testing kits, especially in developing countries, there is a crucial need to rely on alternative diagnosis methods. Deep learning architectures built on image modalities can speed up the COVID-19 pneumonia classification from other types of pneumonia. The transfer learning approach is better suited to automatically detect COVID-19 cases due to the limited availability of medical images. This paper introduces an Optimized Transfer Learning-based Approach for Automatic Detection of COVID-19 (OTLD-COVID-19) that applies an optimization algorithm to twelve CNN architectures to diagnose COVID-19 cases using chest x-ray images. The OTLD-COVID-19 approach adapts Manta-Ray Foraging Optimization (MRFO) algorithm to optimize the network hyperparameters’ values of the CNN architectures to improve their classification performance.

Ultrawideband (UWB)-based precise short-range localization for wireless power transfer to electric vehicles in parking environments
Authors: Lee Seung-Mok
Published: May 2021

As the necessity of wireless charging to support the popularization of electric vehicles (EVs) emerges, the development of a wireless power transfer (WPT) system for EV wireless charging is rapidly progressing. The WPT system requires alignment between the transmitter coils installed on the parking lot floor and the receiver coils in the vehicle. To automatically align the two sets of coils, the WPT system needs a localization technology that can precisely estimate the vehicle’s pose in real time. This paper proposes a novel short-range precise localization method based on ultrawideband (UWB) modules for application to WPT systems. The UWB module is widely used as a localization sensor because it has a high accuracy while using low power. In this paper, the minimum number of UWB modules consisting of two UWB anchors and two UWB tags that can determine the vehicle’s pose is derived through mathematical analysis. The proposed localization algorithm determines the vehicle’s initial pose by globally optimizing the collected UWB distance measurements and estimates the vehicle’s pose by fusing the vehicle’s wheel odometry data and the UWB distance measurements. To verify the performance of the proposed UWB-based localization method, we perform various simulations and real vehicle-based experiments.

Contemporary and very intense pace of life and work has highlighted the importance of studying burnout syndrome that is currently used to describe a wide range of jobs and occupations. The purpose of the research is to examine the perceptions of primary education teachers about the reasons that cause burnout, as well as the measures taken by the principal in order to cope it. The research was carried out between February 2019 and April 2019 with the method of an anonymous self-completing questionnaire. All teachers working in school units, regardless of their specialty, were selected from the schools belonging to the Regional Unit of Kavala in Greece. A number was assigned to each unit, which was then recorded in a statistical table. From this table, 30 numbers were randomly selected representing 30 different schools, irrespective of their location and organisation. The sample of the research consists of 324 Primary Education teachers. The findings revealed that teachers do not feel particularly professionally exhausted or emotionally exhausted due to their profession, but instead they feel creative, believe that their goals are achieved and are willing to carry out their educational work - duty. Furthermore, as far as the feeling of personal achievement and satisfaction that teachers feel is concerned, the attitude of the principal and his/her contribution to the effectiveness of the educational leadership play an important role.

The development of mathematical skills, especially those specific to geometry, for the primary cycle is a triple challenge in the current context of education in Romania. The first of the challenges is given by the fact that classical education, but also the online one, has become an activity, still unstructured, concerning movements, decisions, and political pressures, implicitly with the changes that occurred in the ministerial apparatus. The second challenge is given by the methodological changes and of the school curriculum, which comes as a completion of the first challenge, being felt even in the teaching-learning-evaluation specific to geometry. The third challenge is given by the weight that teachers face in making geometry a discipline that appeals to students, attractive. In this sense, the challenge for us is to show that this triple barrier can be overcome. As such, the present study proposes a mixed method of presenting the geometric contents in the classroom for the preparatory group, class I and II, through the prism of the instruments offered by the Romanian thematic philately. The results of the study are presented in the form of worksheets, of which we present only fragments to summarize the possibilities arising from the association of thematic philately with notions of geometry.

Estimation of runoff in a watershed is very important to manage the water resources efficiently. In this regard, surface runoff quantification is an essential study. The main objective of this study is to quantify the surface runoff of the catchment area of a well located in AEC & RI, TNAU, Kumulur, Trichy District of Tamil Nadu State, India. An attempt also made to analyze the surface runoff by SCS-CN event and annual basis as well as by modified runoff-coefficient method. This study identified the variation of runoff volume within different approaches of SCS-CN method and runoff coefficient method. By using GPS and GIS techniques catchment area of a well and slope direction was delineated. With the help of GIS tools and remote sensing technology with ground truth verifications, the land use/ land cover and soil maps were delineated for the study area. Sandy loam and sandy clay loam type of soils are predominating and HSG ‘C’ was identified for the study area. The highest CN value is 92 and the maximum runoff coefficient value is 0.95 for the Built-up land, the lowest CN value is 71 and the lowest runoff coefficient is 0.11 for the area covered with trees. Three AMC conditions were considered while estimating runoff volume by SCS-CN event approach. Among 15 years of rainfall data from 2004 to 2018, the highest runoff 38452.36 m3 was generated in the year 2005 and the lowest runoff 8718.29 m3 was generated in 2018 by SCS-CN event basis method. From this study between two concepts of SCS-CN and runoff coefficient models, the SCS-CN model with an event basis approach is yielding productive results. For quantifying surface runoff and for planning water conservation structures event basis calculations are more effective.

Published: May 2021

In this paper, Bayesian inference is used to estimate the parameters, survival, hazard and alternative hazard rate functions of discrete Gompertz distribution. The Bayes estimators are derived under squared error loss function as a symmetric loss function and linear exponential loss function as an asymmetric loss function. Credible intervals for the parameters, survival, hazard and alternative hazard rate functions are obtained. Bayesian prediction (point and interval) for future observations of discrete Gompertz distribution based on two-sample prediction are investigated. A numerical illustration is carried out to investigate the precision of the theoretical results of the Bayesian estimation and prediction on the basis of simulated and real data. Regarding the results of simulation seems to perform better when the sample size increases and the level of censoring decreases. Also, in most cases the results under the linear exponential loss function is better than the corresponding results under squared error loss function. Two real lifetime data sets are used to insure the simulated results.
Utilization of the Karnaugh Map in Exploring Cause-effect Relations Modeled by Partially-defined Boolean Functions
Authors: Rushdi Ali Muhammad Ali , Badawi Raid Salih
Published: May 2021

This paper utilizes a modern regular and modular eight-variable Karnaugh map in a systematic investigation of cause-effect relationships modeled by partially-defined Boolean functions (PDBF) (known also as incompletely specified switching functions). First, we present a Karnaugh-map test that can decide whether a certain variable must be included in a set of supporting variables of the function, and, otherwise, might enforce the exclusion of this variable from such a set. This exclusion is attained via certain don’t-care assignments that ensure the equivalence of the Boolean quotient w.r.t. the variable, and that w.r.t. its complement, i.e., the exact matching of the half map representing the internal region of the variable, and the remaining half map representing the external region of the variable, in which case any of these two half maps replaces the original full map as a representation of the function. Such a variable exclusion might be continued w.r.t. other variables till a minimal set of supporting variables is reached. The paper addresses a dominantly-unspecified PDBF to obtain all its minimal sets of supporting variables without resort to integer programming techniques. For each of the minimal sets obtained, standard map methods for extracting prime implicants allow the construction of all irredundant disjunctive forms (IDFs). According to this scheme of first identifying a minimal set of supporting variables, we avoid the task of drawing prime-implicant loops on the initial eight-variable map, and postpone this task till the map is dramatically reduced in size. The procedure outlined herein has important ramifications for the newly-established discipline of Qualitative Comparative Analysis (QCA). These ramifications are not expected to be welcomed by the QCA community, since they clearly indicate that the too-often strong results claimed by QCA adherents need to be checked and scrutinized.

The application of nontoxic 2D transition‐metal carbides (MXenes) has recently gained ground in bioelectronics. In group‐4 transition metals, tantalum possesses enhanced biological and physical properties compared to other MXene counterparts. However, the application of tantalum carbide for bioelectrodes has not yet been explored. Here, fluorine‐free exfoliation and functionalization of tantalum carbide MAX‐phase to synthesize a novel Ta4C3Tx MXene‐tantalum oxide (TTO) hybrid structure through an innovative, facile, and inexpensive protocol is demonstrated. Additionally, the application of TTO composite as an efficient biocompatible material for supercapacitor electrodes is reported. The TTO electrode displays long‐term stability over 10 000 cycles with capacitance retention of over 90% and volumetric capacitance of 447 F cm−3 (194 F g−1) at 1 mV s−1. Furthermore, TTO shows excellent biocompatibility with human‐induced pluripotent stem cells‐derived cardiomyocytes, neural progenitor cells, fibroblasts, and mesenchymal stem cells. More importantly, the electrochemical data show that TTO outperforms most of the previously reported biomaterials‐based supercapacitors in terms of gravimetric/volumetric energy and power densities. Therefore, TTO hybrid structure may open a gateway as a bioelectrode material with high energy‐storage performance for size‐sensitive applications.
