La tradición ibérica del aleluya vespertino en la Edad Media: un caso paradigmático de transferencia de formularios de la misa al oficio divino
Authors: Ruiz Torres Santiago
Published: June 2022

Durante la Baja Edad Media, y hasta la reforma tridentina, existió la costumbre en las iglesias hispanas de cantar el aleluya de la Misa en las segundas vísperas de las solemnidades más importantes del calendario litúrgico; en su caso, remplazando al himno, y más excepcionalmente, al responsorio, el versículo simple o la secuencia-prosa. Esta extraña peculiaridad, apenas conocida hasta la fecha, plantea una serie de interrogantes de sugestivo análisis: ¿cuál fue el origen de esta tradición? ¿En qué grado estuvo extendida por la geografía peninsular? De igual modo, ¿cuáles fueron las festividades que prescribieron la interpretación del aleluya de la Misa en vísperas? ¿Hasta qué punto es estable su elección, así como la manera de combinarse con otros ítems litúrgicos? ¿Qué peculiaridades encierra la entonación de estos aleluyas? Y por último, ¿cómo se refleja esta tradición en las fuentes? El propósito perseguido en este artículo es arrojar luz sobre estas cuestiones en orden a posibilitar un mejor conocimiento del ritual tardomedieval hispano. Para ello, se ha consultado un amplio elenco de testimonios litúrgicos peninsulares —tanto diocesanos como monásticos— fechados entre los siglos XI y XVI. En modo análogo, ahondamos en las razones litúrgicas que provocaron este singular trasplante, así como en los factores que alentaron su difusión por el panorama ibérico.
Experiencias de cultura escrita en el Císter malagueño: Beatriz de San Francisco, abadesa del convento de Recoletas Bernardas y de la abadía de Santa Ana (1619-1658)
Authors: Marchant Rivera Alicia
Published: June 2022

El objetivo del presente estudio es el de analizar el Libro de Actas de toma de hábito y profesión de las Recoletas Bernardas de Málaga (luego, desde 1650 en adelante, de la abadía cisterciense de Santa Ana) desde la perspectiva que nos aportan sus notas marginales y textos intercalados, los cuales, aparte de indicar las fechas y descriptores de las tomas de hábito y profesión de las religiosas del convento, su finalidad ordinaria, ofrecen pequeñas biografías, necrológicas, crónicas históricas y memoria cultural de la vida de clausura. Todo ello a través del hilo conductor del periodo abacial de la madre Beatriz de San Francisco (1619-1658), quien de forma intermitente pero muy continuada ocupó la abadía del cenobio durante un periodo de más de treinta años, convirtiéndose en protagonista y ejecutora de gran parte de las experiencias de cultura escrita aglutinadas en el texto. Todo ello en aras de contribuir al estudio y la reconstrucción de la cultura escrita femenina española en pleno ecuador de la Edad Moderna.
El partido Católico Nacional en México (1911-1914): ¿fenómeno clerical o expresión de participación política del laicado católico?
Authors: González Morfín Juan
Published: June 2022

Después de años de ausencia en el terreno de la política en México, en 1911 los católicos reaparecieron en un partido que tomó el nombre de católico. En algunos estados, obtuvo éxitos contundentes que avivaron el recelo de los partidos liberales. Desde su nombre tuvo la impronta clerical y, en sus acciones, algunas veces no se distinguía si quienes lo integraban eran realmente independientes de la jerarquía o una extensión suya para actuar en política. En este artículo se analizará si en su breve trayectoria, esta organización, consiguió sus objetivos de impregnar la administración pública y el orden legal con los principios cristianos, o se vio limitada en sus intentos al no distinguir el límite de lo que pertenecía a la religión y lo que era propio de la política. También se profundizará en los efectos positivos o negativos que puede tener, a la hora de hacer política, una interdependencia de los laicos de una religión con sus jerarcas.
How Fablabs Manage the Knowledge They Create
Authors: Maravilhas Sérgio , Martins Joberto
Published: June 2022

A collaborative space for stimulating creativity is a place of learning through the exchange and sharing of knowledge and experience among its members. It allows the leveraging of innovation through the use of technological resources available in the space, stimulating the creativity of its participants, enabling the development of products and solutions based on personal projects—do it yourself (DIY)—from ideation, or the construction supported on knowledge developed by other elements together, collaboratively, enhancing the final result—do it with others (DIWO). A research project is being held to create a new lab, or transform and adapt one of the existing lab's, in a Fab Lab or a Maker Space to let students, teachers, and staff give wings to their imagination and develop innovative solutions to solve real problems while they interact and exchange tacit knowledge, making it explicit after concluding their projects when they share their research reports.
Self-Directed Learning in the Age of Open Source, Open Hardware and 3D Printing
Authors: Novak James I
Published: June 2022

This chapter investigates the role of online communities in the future of learning. It considers the paradigm shift from the “push” of more formal educational models, to the notion of “pull” whereby people actively pursue personalized learning experiences. Empowered by the internet and the ability to access information and connect to each other at any time, massive online communities are building vast pools of information around specialized topics such as 3D printing, coding and electronics. This chapter discusses the role of digital technologies in transforming educational models. It provides an argument that practice-led, self-directed research is changing the way people engage with learning. The argument is supported by examples of practice from online communities, university and school education, drawing together key considerations for the future of education that are particularly relevant for technology and educational researchers, teachers across disciplines and those developing higher-level curriculum directives.
Using 3D Printing as a Strategy for Including Different Student Learning Styles in the Classroom
Authors: Fernandes Susana C. F. , Simoes Ricardo
Published: June 2022

This chapter aims to explore the contribution of 3D printing technologies as a collaborative resource in higher education teaching. It was conducted in the course “Physics of Materials,” in which the contribution of practical experience in the learning process was analyzed and the degree of interest, motivation, and understanding by students on academic content was assessed. Practical demonstrations with resources prepared by 3D printing can be a very motivational learning facilitator. To this end, the learning styles of students were determined through the Honey-Alonso learning styles questionnaire (CHAEA). A second questionnaire was used to obtain information about the motivational importance of 3D printing technology in teaching activities in the classroom. The authors concluded that 3D printing can positively help teachers to improve students' engagement and proactive behavior, as well as teaching environment, by including different methodological styles in the learning process, particularly in courses with a significant theoretical content.
Virtual Reality, 3D Recreations and 3D Printing in Social Sciences Education
Authors: Delgado-Algarra Emilio José
Published: June 2022

Virtual reality is a technology for the relocation and interaction of users with a digital environment created by computers through an interface that recognizes actions carried out in the real world. It allows users a multimodal experience, making possible immersion in a digital world. On the other hand, 3D modeling is a process of design and representation of an object (3D model) in three dimensions with specialized software, a model that could become tangible through 3D printing. Virtual reality, 3D modeling, and 3D printing technologies, with appropriate teaching proposals and appropriate tools for process monitoring, offer students new ways of interacting with contents of social sciences, geography, and history. There are more resources for the management of classes with VR devices and specific VR applications for teaching. In general, virtual reality and 3D modeling/painting in class allows both interaction and several opportunities for learning adapted to the needs of students.
Using OpenSCAD for Teaching Mathematics
Authors: Liziero André Rafael , Basniak Maria Ivete
Published: June 2022

Three-dimensional representations have been used in teaching for several decades. However, these representations were made primarily using materials available in the market. The use of 3D printers has extended the possibility of creating and printing these objects, enabling the printing of three-dimensional models using computer designs. These computational designs or 3D computational modeling are built employing various software programs, which require reflections and strategies during their production. In this chapter, the authors discuss the possibilities of using the OpenSCAD software 3D models for teaching mathematics.
Peer Activity Approach for Engineering Students to Understand Robotics Course
Authors: Fusic S. Julius , Anandh N.  , Hariharan Kaluvan , Leando I.
Published: June 2022

This article provides the overview and conceptual explanation of a robotic course using a peer learning activity. In this approach, the demo-based peer teaching education activity was performed to improve the engineering education system. Strategies that relate to student experiences and engage their interests can be difficult to glean and execute in a short duration. The introduction of a demo-based learning method reduces complexity and time frame to complete for students. Initially, the prototype was developed using a 3D printer and it is used to explain the mobile robot concepts through peer teaching techniques to undergraduate students. The activity results were used to study the peer teaching impact among the student's group through weighted average and correlation coefficient method. Through demo assignments and assessment the results justify the improvement of students self-confidence, interest towards the course, perspective thinking, student to student interaction and teamwork.

Published: June 2022

Makerspaces are common learning spaces providing hands-on opportunities for students to make, create, plan, and play. This chapter describes an equity-oriented (girls) makeathon day. Teacher and teacher candidate participants (n=15) acted as mentors for 22 girls creating wearable technologies, augmenting reality using old t-shirts, and creating a mobile app related to an issue that teen girls face today. The results of this case study focus on results from an adapted questionnaire (teacher efficacy and attitudes toward STEM [T-STEM]) and semi-structured interviews. Qualitative data of this case study research was analyzed through open-coding and triangulated with quantitative data and Mann-Whitney U tests. Participants identified the importance of technologies for their growth as educators and to create safe and supportive environments for girls. Participants highlighted the importance of professional development and support and how to create effective makerspaces. Continued research and opportunities need to be created to encourage diverse educational makeathon events.
Adding a New Dimension to Teaching Mathematics Educators
Authors: Wan Anna , Ivy Jessica
Published: June 2022

Technology has the potential to transform the classroom, build access to new mathematical content, and provide access to students through unique representations. For this study, the authors considered the transformational promise of digital fabrication technology, specifically 3D printing, in a setting comprised of pre-service teachers. An introduction to digital fabrication session was implemented in a secondary mathematics methods course. Participants were assessed both prior to the experience and after, using an adapted TPACK developmental self-report survey to consider TPACK themes and subthemes. In this chapter, the authors describe ideas that emerged from narratives provided by participants, patterns of change noted from pre- to post-assessment, and three cases that emerged representing students who experienced the most positive changes, most negative changes, and least amount of change on self-perceived levels.
Mental Zooming as Variable Asset Integration in Inter-Temporal Choice
Authors: Holden Stein T. , Sommervoll Dag Einar , Tilahun Mesfin
Published: June 2022

Our time preferences deviate systematically from that of Homo economicus. They seem to be driven by a form of mental zooming, where higher and more distant amounts induce a more holistic perspective in contrast to smaller and near future amounts. We model zooming as variable asset integration and ask whether this can explain the observed variation in discount rates in experiments. It can. Equally important, the zooming for both time and magnitude is similar across two countries (Ethiopia and Malawi) and within a country (Ethiopia).

Diagnosis of nonalcoholic fatty liver disease
Authors: Manilgama S. R. , Hettiarachchi N. M.
Published: June 2022

The diagnosis of nonalcoholic fatty liver disease (NAFLD) relies on confirmation of the presence of hepatic steatosis in more than 5% of hepatocytes by either imaging or histology without demonstrable secondary cause such as alcohol consumption, medications, hereditary or autoimmune disorders. NAFLD begins with simple steatosis that may later progress to steatohepatitis and end-stage liver cirrhosis. The differentiation of simple steatosis from steatohepatitis carries a prognostic value. Patients with steatohepatitis are at high risk of both liver and cardio-vascular related morbidity and mortality. NAFLD should be clinically suspected in individuals diagnosed with metabolic syndrome and metabolic risk factors. Liver enzymes are not reliable in diagnosing either hepatic steatosis or steatohepatitis, but the presence of abnormal liver functions should alert the clinician to arrange NAFLD workout. Advanced imaging techniques and various scoring systems are helpful to detect the extent of the disease non-invasively. Although, liver histology is considered the gold standard investigation in diagnosing and staging the disease, the liver biopsy is invasive and technically demanding.

Authors: Dutta Deep , Mohindra Ritin , Mahajan Kunal , Sharma Meha
Published: June 2022

Background: No meta-analysis has analysed efficacy and safety of fast-acting aspart insulin (FIAsp) with insulin pump in type 1 diabetes mellitus (T1DM).Methods: Electronic databases were searched for randomised controlled trials (RCTs) involving T1DM patients on insulin pump receiving FIAsp in intervention arm, and placebo/active comparator insulin in control arm. Primary outcome was to evaluate changes in 1- and 2-hour post-prandial glucose (1hPPG and 2hPPG). Secondary outcomes were to evaluate alterations in percentage time with blood glucose <3.9 mmol/L (hypoglycaemia), time in range (TIR) blood glucose 3.9 to 10 mmol/L, insulin requirements and adverse events.Results: Data from four RCTs involving 640 patients was analysed. FIAsp use in insulin pump was associated with significantly greater lowering of 1hPPG (mean difference [MD], –1.35 mmol/L; 95% confidence interval [CI], –1.72 to –0.98; P<0.01; I2=63%) and 2hPPG (MD, –1.19 mmol/L; 95% CI, –1.38 to –1.00; P<0.01; I2=0%) as compared to controls. TIR was comparable among groups (MD, 1.06%; 95% CI, –3.84 to 5.96; P=0.67; I2=70%). Duration of blood glucose <3.9 mmol/L was lower in FIAsp group, approaching significance (MD, –0.91%; 95% CI, –1.84 to 0.03; P=0.06; I2=0%). Total hypoglycaemic episodes (risk ratio [RR], 1.35; 95% CI, 0.55 to 3.31; P=0.51; I2=0%), severe hypoglycaemia (RR, 2.26; 95% CI, 0.77 to 6.66; P=0.14), infusion site reactions (RR, 1.35; 95% CI, 0.63 to 2.93; P=0.77; I2=0%), and treatment-emergent adverse events (RR, 1.13; 95% CI, 0.80 to 1.60; P=0.50; I2=0%) were comparable.Conclusion: FIAsp use in insulin pump is associated with better post-prandial glycaemic control with no increased hypoglycaemia or glycaemic variability.
The endovascular aortic repair for patients with traumatic thoracic aortic blunt injury
Authors: Ye Mengmeng , Zhou Qingyun , Wei Yiqing , Wu Jiacheng , Shen Yiming , Zheng Tao , Shao Guofeng
Published: June 2022

OBJECTIVE:

Blunt thoracic aortic injury is the second most common cause of death in trauma patients. Traumatic aortic injury is an emergency that patients will face death soonly, even there is no enough time to transport the patient to the hospital. In our center, all patients were treated with thoracic endovascular aortic repair (TEVAR). We retrospectively analyze the therapeutic effects of TEVAR of blunt traumatic aortic injury (BTAI) to get some inspiration for the follow-up treatment and provide valuable guidance.

METHODS:

We retrospectively reviewed our institutional database to identify all patients treated with TEVAR for traumatic lesions of the aortic isthmus. We have identified 22 patients since 2017. Patients’ charts were analyzed for preoperative characteristics and intraoperative variables.

RESULTS:

Forty-six patients were included. The median age was 56 years (23–79 years). Sixteen patients were male (73%). Most of them were graded III/IV of aortic injury. All patients were undergone endovascular treatment successfully. Six of 22 patients, showing no chest pain before admission, were presented with classic type B aortic dissection. Moreover, one patient was presented with thoracoabdominal dissection. Emergency surgery (<24 h) was performed in seven patients (32%) who experienced life-threatening injury resulting in hemorrhagic shock and hematoma formation in the mediastinum. All patients were discharged smoothly with no residual symptoms.

CONCLUSIONS:

Endovascular treatment of traumatic aortic dissection reduces the mortality rate of these patients who cannot tolerate traditional open surgery. According to our experience, patients who presented with simple pseudoaneurysm in enhanced computed tomography were more stable. Therefore, a postponed operation could be recommended after symptomatically hypotensive management. However, emergency surgery was necessary if patients presented with obviously mediastinal hematoma, especially progressive pleural effusion, which could result in hematoma rupture and death.
A review on electroencephalography (EEG)-controlled upper limb exoskeletons towards stroke rehabilitation
Authors: Gao Xin , Clarke Robert , Zhang Dingguo
Published: June 2022

Stroke is a significant cause of disability in both developing and developed countries. This can cause a severe financial burden on families and society. With the development of robotics and brain-computer interfaces (BCIs), robotic exoskeletons and BCIs have received increasing clinical attention on stroke rehabilitation. Electroencephalography (EEG) is a method of recording brain signals non-invasively, which can be used as a BCI to control exoskeletons. This review focuses on rehabilitation systems of EEG-controlled upper limb exoskeletons, including the newest research progress and clinical evaluation in recent years. From the review, we find EEG-controlled exoskeletons can positively contribute to stroke rehabilitation. However, there are some issues that should be well investigated. More efforts are needed on EEG signal decoding algorithms such as deep learning methods in the clinical context. Practical applications must also bridge the gap between offline experiment and online control. In addition, this review also discusses the impact and significance of shared control, virtual reality/augmented reality, and other ways of human-computer interaction to improve EEG-controlled exoskeletons.
Erythrasma – A Red Herring in the Ongoing Epidemic of Tinea
Authors: Ramesh V. , Passi Shanta
Published: June 2022

We describe the presentation of five adults with erythrasma, misdiagnosed as tinea and prescribed antifungal treatment which resulted in incomplete clearance. The lesions were restricted to axillary and/or inguinal folds. They were dry, brown macules with fine scaling. Except for one with moderate pruritus, they were asymptomatic. No fungal elements could be demonstrated in any of the patients in 10% KOH preparation. Gram stain revealed short gram-positive rods in varying proportions. All the patients showed a pink fluorescence on Wood’s lamp examination. After treatment with topical clindamycin singly or in combination with oral azithromycin, there was complete clearance of the lesions leaving normal-appearing skin in three and residual hyperpigmentation in one. The overdiagnosis of tinea in the ongoing epidemic of dermatophytosis is a potential concern. Wood’s lamp examination is very useful to confirm or exclude erythrasma.

Authors: Bains Anupama , Alam Afroz , Singh Saurabh , Budania Anil , Patra Suman , Bhardwaj Abhishek
Published: June 2022

Background:

Telemedicine has emerged as an important tool in providing patient care during the COVID-19 pandemic. Hence, we aimed to study the clinico-epidemiological profile of patients seen in the teledermatology outpatient department (OPD) during the COVID-19 pandemic.

Material and Methods:

Retrospective data analysis of records of patients, who consulted in telemedicine OPD from 20 April 2020 to 5 Feb 2021 was done.

Results:

Out of 2524 patients registered for teledermatology consultation, 2117 completed the process of teleconsultation. The mean age of patients was 35.59 ± 15.60 years. There was a male preponderance with 1372 (64.81%) patients while females were 745 (35.19%). 1773 (83.75%) patients were managed on telemedicine alone and 344 (17.42%) patients required face to face physical consultation. The most common disorder was dermatophytosis seen in 316 (17.82%) followed by hair disorders like androgenetic alopecia and telogen effluvium in 239 (13.48%), acne in 238 (13.42%) and dermatitis in 196 (11.05%). Blood investigations were advised in 365 (17.24%) patients and skin biopsy was advised in 23 (1.09%) patients. The major causes for incomplete teleconsultation procedure were no response to telephone calls in 207 (8.2%), 76 (3.01%) patients had taken a prior consultation and 60 (2.37%) patients didn’t give consent for teleconsultation.

Conclusion:

Common dermatological diseases like tinea, acne, hair disorders and dermatitis can be managed on telemedicine alone. In India, there are fewer dermatologists per population, therefore telemedicine can be continued even after the pandemic is over in cases where diagnoses and treatment are straight forward.
Radiological Imaging in Nail Unit Disorders (Part I) - Modalities Used
Authors: Grover Chander , Bansal Shikha , Varma Ameeta , Jakhar Deepak
Published: June 2022

The nail unit is a unique skin appendage, capable of mounting only a limited number of reaction patterns to a variety of insults. This makes it difficult to diagnose many nail conditions based on clinical features alone. Thus, diagnostic modalities have an important role to play in nail disorders. Emphasis is placed on non-invasive diagnostic methods, of which, radiological imaging forms an important part; however, it is a field largely under-explored with very few studies and reports available in the literature. This could be due to the problems encountered in nail unit radiology including its small size, complex anatomy, requirement for special high-frequency probes to reliably evaluate superficial structures, and non-familiarity with nail unit radiological features even amongst trained radiologists. Nevertheless, it plays a useful role in diagnosing nail disorders (especially tumors), localizing the changes, exploring differential diagnoses, estimating prognosis, and planning management. This article is aimed at collating scientific data pertaining to various radiological modalities used in the diagnosis of nail diseases. The advantages and limitations of various imaging techniques used for evaluating the nail unit, including digital radiographs, high-frequency ultrasound, ultrasound doppler (USD), computed tomography (CT), and magnetic resonance imaging (MRI), are discussed in the first part. The second part will discuss the features of common and uncommon nail diseases.
Extrafacial Melasma
Authors: Daroach Manju , Vinay Keshavamurthy , Bishnoi Anuradha , Parsad Davinder , Kumaran Muthu Sendhil
Published: June 2022

Background:

Extrafacial melasma is a rare presentation, commonly occurring in postmenopausal women with a poor etiological insight and nature of its course. We planned to decipher the natural course of extrafacial melasma based on history questionnaire.

Materials and Methods:

Patients with diagnosis of extrafacial melasma were recruited. After informed consent, complete history including age of onset, duration, progression, sites of involvement (initial site as well as current site of pigmentation), treatment history, history of drug intake, family history, associated other diseases, and clinical photography and dermoscopy were done.

Results:

Fifteen extrafacial melasma patients were recruited. All were females with mean age of 51.2 years. History of facial melasma in past was given by 93% of recruited patients. Mean total duration of melasma was 23 years. Ten (66%) patients had centrofacial melasma to begin with, 4 (26%) patients had malar melasma, and 1 (6.6%) had extrafacial melasma as initial presentation. Currently all patients had extrafacial melasma. Mean time for clearance of central face melasma was 18.2 years and appearance of melasma at extrafacial sites was 20 years.

Conclusions:

We infer that different clinical patterns of melasma occur sequentially over the natural course of disease and centrofacial melasma as the initial presentation in majority of our patients, progressed to involve extrafacial sites with time.
Prevalence and Patterns of Latex Glove Allergy among Healthcare Workers in a Tertiary Care Center In South India - A Cross-Sectional Study
Authors: Sakkaravarthi Vinupriya , Chandrashekar Laxmisha , Rajappa Medha
Published: June 2022

Background:

Latex glove allergy and its impact on healthcare workers (HCWs) have been studied in many countries, but the data is scarce from developing countries.

Objectives:

We wanted to estimate the prevalence and patterns of latex glove allergy among HCWs and to study the factors associated with it.

Materials and Methods:

We conducted a cross-sectional study among 1088 HCWs of a tertiary care center in South India with the screening questionnaire adopted from “Allergy and Asthma network.” Skin prick test, patch test, and serum total immunoglobulin E (IgE) were performed only in consenting symptomatic HCWs.

Results:

The prevalence of latex glove allergy in our study subjects was 9.1% (99/1088). This includes latex protein allergy and contact dermatitis to rubber glove allergens. The most common manifestation of latex glove allergy was irritant contact dermatitis observed in 68 HCWs (68.6%). Other presentations were allergic rhinitis (40.4%), allergic contact dermatitis (17.1%), contact urticaria (11.1%), allergic conjunctivitis (6.06%), and asthma (3.03%). The risk factors associated with latex glove allergy in our study were atopy (OR = 20.51), working in both ward and operation theater (OR = 26.6), auxiliary staff (OR = 4.75), and more than ten years of hospital work experience (OR = 3.85).

Conclusion:

Our study reported a high prevalence of latex glove allergy. With irritant contact dermatitis being the most common manifestation in our study, HCWs at risk shall be educated on the appropriate use of gloves and hand moisturizer to prevent occupational irritant contact dermatitis (ICD). We recommend further research to address the gaps in our knowledge around latex allergy in a healthcare setting.

Impact of COVID-19 Pandemic Induced Lockdown on Management of Myocardial Infarction
Authors: Ponde Chandrashekar K. , Jain Dharmendra , Suresh Manjula , Gunasekaran Sengottuvelu , Mishra Sundeep , Alexander Thomas , Nair Tiny
Published: June 2022

Background:

COVID-19 has induced a change in the management of myocardial infarction (MI).

Methods:

We developed a customized technological virtual response system for mapping exercise, during August 14–28, 2020, to understand the management of MI. Prior telephonic consent was obtained, and the weblink of the questionnaire was provided on individual WhatsApp. Anonymized data were statistically analyzed by GraphPad software version 8.4.3.

Results:

The mean year of experience in active clinical practice was 12 years (standard deviation 10, 95% confidence interval 12–13). There were 41% (n = 445) participants who reported reduction by 25%–29% of MI patients, reporting to hospital, followed by 27.8% (n = 302) participants, reporting that <25% patients with MI approached the hospital. Sixty percent reported as the most important reason for a decrease in cases of MI patient's fear of contracting COVID-19 (n = 648), followed by limited transportation by 20.49% (n = 222) participants. There were health-care-driven reasons for a decrease in MI primary percutaneous coronary intervention activations. These included cardiologist's reluctance to do primary percutaneous cardiovascular interventions (PCI) due to COVID-19 and patients presenting late beyond the optimal window for PCI/thrombolysis by 34.71% (n = 376) and 31% (n = 341) of participants, respectively. There were 68.5% (n = 742) of respondents that were of opinion that the time component of MI care that has increased most was time between symptom onset to first medical contact, followed by time between medical contact to catheterization laboratory arrival, as opined by 20% (n = 217) of the participants. It was reported that patients undergoing no reperfusion due to delayed treatment were increased to less than 25%, as reported by 43.4% (n = 471), respondents. This was followed by 32.5% (n = 352), respondents reporting that there was 26%–50% increase in the number of patients undergoing no reperfusion due to delayed treatment. Immediate thrombolysis was preferred by 28% (n = 304) of participants from the teaching institutions. There were 75.1% (n = 814) of the participants, that tested patients for COVID-19 before shifting to the catheterization laboratory.

Conclusion:

This is one of the largest perception mapping exercises, limited with the absence of actual patient data, which is a cohesive reflection in line with global evidence for a remarkable decrease in cases and interventions for the management of MI. The lessons from the experiences entail that there is a need to encourage patients with symptoms suspected of MI to promptly contact emergency services to enable timely diagnosis and enable reperfusion therapy. Impact on the MI management appears to be substantial, which calls for action for change in infrastructure and policy framework to improvise MI care.
A Severe Electrothermal Ring Burn Case and a Proposed Treatment Algorithm
Authors: Özkan Burak , Albayati Abbas , Savran Suleyman , Uysal Cagri Ahmet
Published: June 2022

Ring-associated burns are infrequent comprising only a tiny fraction of burn consults. Due to the circular nature of rings, these burns are often circumferential, with an increased risk for compartment syndrome and neurovascular injury. The severity of ring burn is related to the type of material and electrical current. Low-voltage injuries are generally due to contact with batteries and household devices, while high-voltage electric injuries occur with occupation-related accidents or natural disasters. Low-voltage ring burn can be managed conservatively with close follow-up. However, high-voltage ring burn might have dramatic consequences such as finger amputation. To date, there have been few cases reported in the literature of a ring burn. Most cases were superficial burns and managed with secondary healing or skin grafting. However, the literature has not reported the management of a severe ring burn with deteriorated finger circulation. In this case report, we present a circumferential electrothermal ring burn case with resulted in total loss of a finger. Furthermore, we propose an algorithmic approach to ring burn injuries.
On ternary Diophantine equations of signature over number fields
Authors: Isik Erman , Kara Yasemin , Ozman Ekin
Published: June 2022

In this paper, we prove results about solutions of the Diophantine equation
$x^p+y^p=z^3$
over various number fields using the modular method. First, by assuming some standard modularity conjecture, we prove an asymptotic result for general number fields of narrow class number one satisfying some technical conditions. Second, we show that there is an explicit bound such that the equation
$x^p+y^p=z^3$
does not have a particular type of solution over
$K=\mathbb {Q}(\sqrt {-d})$
, where
$d=1,7,19,43,67$
whenever p is bigger than this bound. During the course of the proof, we prove various results about the irreducibility of Galois representations, image of inertia groups, and Bianchi newforms.
JKO estimates in linear and non-linear Fokker–Planck equations, and Keller–Segel: $L^p$ and Sobolev bounds
Authors: Di Marino Simone , Santambrogio Filippo

We analyze some parabolic PDEs with different drift terms which are gradient flows in
the Wasserstein space and consider the corresponding discrete-in-time JKO scheme. We prove with
optimal transport techniques how to control the

L^p

and

L^\infty

norms of the iterated solutions in terms of the previous norms, essentially recovering well-known results obtained on the continuous-in-time equations. Then we pass to higher-order results, and in particular to some specific BV and Sobolev estimates, where the JKO scheme together with the so-called “five gradients inequality” allows us to recover some estimates that can be deduced from the Bakry–Émery theory for diffusion operators, but also to obtain some novel ones, in particular for the Keller–Segel chemotaxis model.
A fractional Michael–Simon Sobolev inequality on convex hypersurfaces
Authors: Cabré Xavier , Cozzi Matteo , Csató Gyula
Published: June 2022

The classical Michael–Simon and Allard inequality is a Sobolev inequality for functions
defined on a submanifold of Euclidean space. It is governed by a universal constant independent
of the manifold, thanks to an additional

L^p

term on the right-hand side which is weighted by the
mean curvature of the underlying manifold. We prove here a fractional version of this inequality
on hypersurfaces of Euclidean space that are boundaries of convex sets. It involves the Gagliardo
seminorm of the function, as well as its

L^p

norm weighted by the fractional mean curvature of the
hypersurface.As an application, we establish a new upper bound for the maximal time of existence in the
smooth fractional mean curvature flow of a convex set. The bound depends on the perimeter of the
initial set instead of on its diameter.

We study the Eisenstein ideal for modular forms of even weight

extra reducibility
: the Eisenstein ideal is strictly larger than the ideal cutting out reducible Galois representations. We prove a modularity theorem for these extra reducible representations. As consequences, we relate the derivative of a Mazur–Tate

Defining $R$ and $G(R)$
Authors: Segal Dan , Tent Katrin
Published: June 2022

We show that for Chevalley groups

G(R)

of rank at least 2 over an integral domain

R

each root subgroup is (essentially) the double centralizer of a corresponding root element. In many cases, this implies that

R

and

G(R)

are bi-interpretable, yielding a new approach to bi-interpretability for algebraic groups over a wide range of rings and fields.

For such groups it then follows that the group

G(R)

is (finitely) axiomatizable in the appropriate class of groups provided

R

is (finitely) axiomatizable in the corresponding class of rings.
Proper base change for étale sheaves of spaces
Authors: Chough Chang-Yeon
Published: June 2022

The goal of this paper is to prove the proper base change theorem for truncated coherent étale sheaves of spaces, generalizing the usual proper base change in étale cohomology. As applications, we show that the profinite étale topological type functor commutes with finite products and the symmetric powers of proper algebraic spaces over a separably closed field, respectively. In particular, the commutativity of the étale fundamental groups with finite products is extended to all higher homotopy groups.
Coroneologisms and Word Formation Processes in Hindi-English Codemixed Words
Authors: Qamar Md. Tauseef , Yasmeen Juhi , Zeeshan Md. Arfeen , Pathak Sanket
Published: June 2022

The COVID-19 pandemic came with a flux of new words, terminologies, and phrases, which led to the rapid coinage or neologisms in the world's different languages. These lexical innovations may take place within one language as well as with the combination of two different languages. Therefore, this paper scrutinizes coroneologisms and word-formation processes in Hindi-English code-mixed words. Such a phenomenon happened due to the acceptance of English by Indians besides their mother tongue which makes them bilingual. The data were gathered from newspapers, blogs, social media, TV news, etc. Next, the linguistic analysis of the data revealed different types of word classes in Hindi-English codemixed words such as compounding, affixation, blending, and reduplication. Out of these, compounding and borrowing were reported as the most productive types of coroneologisms in Hindi-English code-mixed words.
A Synchronic and Historical Look at Aklanon Phonology
Authors: Rentillo Philip , Pototanon Ruchie Mark D.
Published: June 2022

Akeanon features a phoneme unique relative to many Philippine-type languages, which is a reflex of the proto-Bisayan *l and *-d-. This was initially described as a voiced velar fricative [ɣ], and later repositioned as both a consonant of an onset and a semivowel of a coda. Half a century later it was reaffirmed as mainly a semivowel. Based on these descriptions of Akeanon, more questions arise as per the true nature of the phoneme in focus. This paper hence provides both a review and reevaluation of Akeanon phonology based on synchronic distribution, dialectology, historical accounts, and acoustic analysis. Results point to the phoneme as a velar approximant [ɰ]. Further recommendations on both descriptive and applied contexts are provided.
Prevalence of antibiotic residues in body organs of pigs slaughtered in Jos, Nigeria
Authors: Anueyiagu K.N. , Nandi S. , Uzochukwu I.A. , Sule S.O.
Published: June 2022

Background: Drug residue is a serious issue for the food chain when antimicrobial substances are inappropriately used or when the withdrawal times before slaughtering the treated animals are not respected. The aim of this study is to determine the prevalence of antibiotic residues in pork  slaughtered for human consumption in Jos South Local Government Area (LGA), Plateau State, Nigeria.

Methodology: A total of 96 samples which included muscles (n=32), liver (n=32) and kidneys (n=32), were randomly collected from Gyel, Kuru, Du,  and Vwang slaughter slabs in the LGA. The three-plate-test (TPT) technique was conducted where three batches of nutrient agar plates were  aseptically prepared and adjusted to pH 6.0, 7.2 and 8.0. Each plate was seeded with isolated Bacillus subtilis and 5 holes were made on the plate  with a sterile cork borer. The holes were inoculated with 80 μl of each organ extract, 10 μg/ml gentamicin (positive control) and distill water  (negative control), and incubated aerobically at 37oC for 18-24 hours. Positive antibiotic residue was shown by a clear zone of inhibition (annular  diameter of ≥ 2 mm) around the holes.

Results: The result showed that 55.2% (53/96) of the organs tested positive for antibiotic residues while 44.8% (43/96) tested negative. The liver had  the highest prevalence of antibiotic residues (68.8%, 22/32), followed by the kidneys (56.3%, 18/32) and the muscles (40.6%, 13/32). The difference in  the prevalence of antibiotic residues between the organs was not statistically significant (𝜒2=5.1391, p=0.0765). Detection of tetracycline at pH 6.0  as highest in the organs while detection of sulphonamides was lowest at pH 7.2.

Conclusion: The determination of antibiotic residues in pork slaughtered for consumption in Jos South LGA of Plateau State, Nigeria posed potential  public health risks. This situation indicates a wide spread uncontrolled use of antimicrobials in pig production, and requires urgent  attention of government to enforce regulations guiding antibiotic use in veterinary settings in Nigeria.

The objective of this work is to determine the height, area, and capacity of two concrete elevated water reservoirs in a Tertiary Institution in Benin City, Nigeria, to serve as reference to existing controls for future monitoring exercise. The two water reservoir involved in reality are of different shapes and sizes. The elevated heights, areas, and capacities of reservoir one and two suspended above their legs are: (8.106m, 362.778m2, 2940.680m3, and 7.485m, 320.400m2, 296.132m3), respectively. The total heights of the reservoir one and two above ground level (AGL) are approximately 22m and 18m. Statistical analysis of uncertainty in height measurement showed, 0.0153 for reservoir one and 0.0412 for reservoir two. The provision of the necessary information by the REM method about the elevated water reservoirs showed its efficacy. This method is recommended for use in the measurement of inaccessible structure/feature. The type of data and information such as provided in this work are required for institutional water board documentation, water use planning, and archival purpose.

Human-wildlife conflicts have become a significant issue in conservation and land management of a protected area. The study examines Hippo-Human relationship in selected communities around Kainji dam in New Bussa, Niger State, Nigeria. Data for the study was collected through pre tested structured questionnaires and analyzed using descriptive statistics. Findings from the results revealed that male Hippopotamus is the highest with 75.0% and that 37% were 50 years and above. Majority of the respondents had no formal education (42.0%). 79% of the respondents recorded that Hippopotamus was present in the study area while 82.0% have had to encounter Hippopotamus attack. The crops that are mostly grown by the respondents in the study area are Maize, Beans, Millet, Guinea corn, Rice and Groundnut. In which maize is the mostly grown and raided by Hippopotamus. The findings revealed that 69.0% of the respondents state that crop raiding is the major conflict. Various preventive measures undertaken include: fire and smoke, watch guarding, trapping, scare crow, thorn fencing and hunting, with fire and smoke being the most preferred by the respondents. The victims of these attacks are willing to prevent the attacks with fire and smoke as against killing the Hippopotamus, they should be encourage by factoring compensation into conservation policy to promote the conservation of this species in the study area.
