Energy Efficiency and Energy Governance: A Stochastic Frontier Analysis Approach
Authors: Barrera-Santana J. , Marrero G.A. , Ramos-Real F.J.
Published: February 2022

This work analyzes the impact of energy governance on energy efficiency in a set of 29 OECD countries. A Stochastic Frontier Analysis (SFA) approach is conducted to estimate the energy efficiency levels in this sample of countries between 2000 and 2015. Energy governance is measured by an Energy Efficiency Governance Index (EEGI) constructed in Barrera-Santana et al. (2020). The results suggest that increasing the average quality of energy governance by 10% could raise energy efficiency levels by around 9.20%, according to the estimate of our preferred SFA model. To achieve this outcome there are two key requirements: set quantified and achievable targets, and carry out an extensive evaluation of the results of energy policies. Our results are robust to different econometric approaches and variations of the EEGI.
RESPONSABILIDADE SOCIAL CORPORATIVA, CONFIANÇA E DESCONFIANÇA NO VAREJO
Authors: Cararo William Rafael , Basso Kenny
Published: February 2022

As práticas da responsabilidade social corporativa podem influenciar tanto a percepção da confiança quanto a desconfiança dos consumidores, dois construtos importantes nos relacionamentos organizacionais. Nessas circunstâncias, se torna relevante a integridade que a empresa transmite para seus stakeholders, agindo como fator mediador de ambos os construtos. Diante disso, neste estudo o fenômeno acima foi analisado através de um experimento desenho fatorial 2x1. A pesquisa analisou o efeito das práticas de Responsabilidade Social Corporativa na percepção da integridade da empresa perante os consumidores, influenciando a confiança e a desconfiança dos mesmos. Os resultados inferem que as atividades de RSC geram um aumento da integridade empresarial e que a mesma atua como variável mediadora da relação entre a responsabilidade social corporativa, a confiança e a desconfiança dos consumidores. Ao demonstrar que a integridade percebida pelos clientes é o mecanismo pelo qual a responsabilidade social corporativa afeta a confiança e, também, a diminuição da desconfiança dos consumidores, o estudo vem a contribuir para a área do marketing.

A pesquisa tem como objetivo geral, com o auxílio do método PRISMA na condução de uma revisão sistemática, identificar quais ações a Administração Pública Federal está promovendo para desenvolver as competências tecnológicas necessárias à integração de servidores idosos no serviço remoto emergencial. Para tanto, foram analisados artigos em língua inglesa, no intuito de verificar fatores apontados como desafios e dificuldades no uso de tecnologias por pessoas idosas. As bases de dados selecionadas para coleta dos artigos foram Scielo, Scopus e Web of Science. Foram determinados os termos de busca com a combinação das palavras ‘elderly’ and ‘technology’ and ‘difficulty’. A construção do portfólio bibliográfico foi realizada de forma sistematizada, procedimento que possibilitou a seleção inicial de 26 artigos. O uso de planilha do Excel viabilizou análise bibliométrica que gerou a seleção final de 18 artigos. Da pesquisa, constatou-se que as ações promovidas pelo Governo Federal são insuficientes e não consideram as possíveis limitações dos trabalhadores idosos. Ao lado disso, há também foco na aquisição de conhecimentos técnicos para manuseio de ferramentas digitais, mas sem haver a criação de ambientes estimuladores de habilidades e atitudes nesse segmento.

Formas de heterogeneidade mostrada não convencionais na constituição da escrita de estudantes universitários
Authors: Metz Mônica Cristina , Capristano Cristiane Carneiro
Published: February 2022

Inserido na vertente dos estudos sobre Letramentos Acadêmicos, o objetivo deste artigo é descrever a criação de duas categorias de formas de heterogeneidade mostrada que emergem na produção escrita de universitários, sob um ponto de vista enunciativo-discursivo. O corpus é composto por 27 respostas a uma questão de prova, elaboradas por acadêmicos do 2º ano de um curso de Letras de uma universidade pública do Paraná, Brasil. A fundamentação teórico-metodológica parte das concepções de heterogeneidade constitutiva e heterogeneidade mostrada da perspectiva enunciativa, bem como, dos critérios de descrição das formas de heterogeneidade mostrada propostos pela mesma autora. A criação de duas novas categorias constitui um resultado das análises das características presentes no corpus que parecem recobrir práticas de escrita de estudantes ainda não descritas em termos enunciativos/discursivos. Essas características levaram à criação das categorias denominadas de “cópia não marcada” e “tentativa de paráfrase”. Embora as duas categorias sejam consideradas problemas de escrita pelas normas acadêmicas, elas traduzem práticas de enunciação escrita recorrentes entre estudantes e representam formas de negociação com o discurso do outro que precisam ser descritas em termos enunciativos/discursivos, para além de uma perspectiva de denúncia de um problema.

An Unusual Presentation of a Lymphatic Malformation in an Adult: A Case Report
Authors: Gilmore Marguerite , Kim Sharon , McDowell Christopher
Published: February 2022

Introduction: Patients commonly present with neck masses to the Emergency Department. The acute presentation of such a mass can be alarming to patients and their families. In this report we discuss a rare etiology of an acutely presenting neck mass in an adult.
Case Report: We present a 19-year-old patient with an acute neck mass. The mass developed abruptly soon after initiation of a new upper body strength-training regimen. The patient’s history was unremarkable for any trauma or constitutional symptoms. Physical examination revealed the mass, which was diagnosed as a lymphatic malformation by imaging. Surgical removal was successful with pathology confirming the diagnosis.
Conclusion: Lymphatic malformations, although rare, may present in adulthood. The acute presentation of a new mass, coupled with a lack of concerning constitutional symptoms, should increase the diagnostic suspicion of a lymphatic malformation.
Critical Point-of-care Ultrasound Diagnosis of Fournier’s Gangrene: A Case Report
Authors: Ramm Lauren , Guidry Kayla , Cirilli Angela , Kurkowski Ellen , Yu Connie
Published: February 2022

Introduction: Fournier’s gangrene is a severe, necrotizing, and potentially fatal, soft tissue infection of the perineum that can be difficult to diagnose clinically. Point-of-care ultrasound (POCUS) has established a critical role in emergency medicine as a quick diagnostic tool due to its safety, accuracy, and cost effectiveness.
Case Report: We present a case in which POCUS was used to rapidly confirm diagnosis in an unstable, severely septic patient presenting to the emergency department with Fournier’s gangrene.
Conclusion: Point-of-care ultrasound can be used to make the diagnosis of Fournier’s gangrene in critical patients when other diagnostic modalities are not feasible due to a patient’s clinical state.
Point-of-care Ultrasound for the Evaluation of Acute Arterial Pathology in the Emergency Department: A Case Series
Authors: Drake Aaran , Dreyer Nicholas , Hoffer Megan , Boniface Keith
Published: February 2022

Introduction: The use of point-of care ultrasound (POCUS) in the evaluation of vascular emergencies including abdominal aortic aneurysm and deep vein thrombosis is well established. However, no current guidelines exist to outline the use of POCUS in the management of acute peripheral arterial pathology.
Case Series: Here, we present a case series that illustrates the utility of POCUS in the assessment of both traumatic and nontraumatic peripheral arterial disease. Direct visualization of the vasculature via B-mode, color Doppler, and pulsed-wave Doppler assisted in the diagnosis of the following: 1) an acute, post-catheterization thrombus of the proximal radial artery; 2) a complete, traumatic radial artery transection; 3) a forearm hematoma with active arterial extravasation; 4) a traumatic arteriovenous fistula; 5) an acute thrombosis of an artery bypass graft; and 6) an infected pseudoaneurysm.
Conclusion: The incorporation of POCUS into patient care allowed for rapid identification of significant peripheral arterial pathology and led to changes in clinical management, expedited patient care, and circumvented potentially harmful complications.

Published: February 2022

Background: Spinal cord injury (SCI) is a severe neurological disease leading to poor quality of life. Objectives: The regenerative effect of adipose-derived mesenchymal stem cells (AD-MSCs) encapsulated into fibrin, and collagen hydrogel scaffolds on a rat model of SCI was investigated using clinical and histopathological examinations. Methods: A total of 18 adult male Wistar rats (250 - 300 g) were prepared and randomly divided into three equal groups, each with six rats, including the control or SCI group (SCI contusion model without treatment), SCI contusion model treated with AD-MSCs encapsulated in fibrin hydrogel, and SCI contusion model treated with AD-MSCs encapsulated in collagen hydrogel groups. Clinically, functional recovery or hindlimb locomotor activity was assessed using Basso, Beattie, and Bresnahan's (BBB) scoring system four weeks post-treatment. The rats were sacrificed at week four post-treatment, and their spinal cords were examined histopathologically. Results: Faster functional recovery indicated with hindlimb locomotor activity was seen in both treatment groups compared to the control group. Severe polio and leuko-myelomalacia associated with disruption of spinal cord structure were identified in the control group. Mild polio and leuko-myelomalacia associated with mild to moderate disruption of spinal cord structure were seen in the collagen hydrogel + AD-MSCs and fibrin hydrogel + AD-MSCs groups. Conclusions: AD-MSCs encapsulated into fibrin and collagen hydrogels, as two of the most promising ECM-based or natural scaffolds have the potential to be developed in neural tissue engineering (NTE), such as for the treatment of SCI.
Parametric study of a solar dryer system for the development and application of solar energy in Sierra Leone

Published: February 2022

A transient mathematical model has been evaluated to determine the principle of a solar crop dryer for drying vegetables (onion). Considering the meteorological conditions of Freetown (Latitude 8.4840 N, Longitude -13.2300 W), the model was developed to determine air temperatures and other operational parameters of the drying system for a day of March 21st. However, the investigated system had effectively reduced the drying process of onion. The developed double-pass solar air collector system showed a low-temperature output in the morning hours and displayed high-temperature results in the afternoon hours. From 8:00 to 16:00, the solar collector generates fluid output temperatures above 50 0 C, with a peak value of 96 0 C occurred at 12:00. The influence of the mass flow rate on the system's thermal efficiency was investigated. It was noticed that for a certain solar radiation value, an increased in the mass flow rate caused an exponential increased in the solar air collector thermal efficiency. Findings also revealed that an increased in the solar collector length led to a slightly decreased in the outlet air temperatures at a mass flow rate of 0.02 kg/s. The influence of increasing drying air temperatures and air velocity within the drying chamber reduces drying time significantly. The drying time for products dried in the first tray is lesser than for products dried in the subsequent trays, owing to temperature variations. The computation findings were verified to previous studies in the literature and observed to be strongly comparable.
Clinical Prediction Models in Epidemiological Studies: Lessons from the Application of QRISK3 to UK Biobank Data
Authors: Parsons Ruth E. , Colopy Glen Wright , Clifton David A. , Clifton Lei
Published: February 2022

Statistical models for clinical risk prediction are often derived using data from primary care databases; however, they are frequently used outside of clinical settings. The use of prediction models in epidemiological studies without external validation may lead to inaccurate results. We use the example of applying the QRISK3 model to data from the United Kingdom (UK) Biobank study to illustrate the challenges and provide suggestions for future authors. The QRISK3 model is recommended by the National Institute for Health and Care Excellence (NICE) as a tool to aid cardiovascular risk prediction in English and Welsh primary care patients aged between 40 and 74. QRISK3 has not been externally validated for use in studies where data is collected for more general scientific purposes, including the UK Biobank study. This lack of external validation is important as the QRISK3 scores of participants in UK Biobank have been used and reported in several publications. This paper outlines: (i) how various publications have used QRISK3 on UK Biobank data and (ii) the ways that the lack of external validation may affect the conclusions from these publications. We then propose potential solutions for addressing these challenges; for example, model recalibration and considering alternative models, for the application of traditional statistical models such as QRISK3, in cohorts without external validation.
Stereotypes and Emblems in the Construction of Social Imagination
Authors: Rautenberg Michel
Published: February 2022

This article develops two figures of the social imagination: the stereotype and the emblem. To start with we explore the notion of social imagination, principally from Emile Durkheim, Gaston Bachelard and Maurine Godelier. Secondly, the article deepens the two notions of stereotypes and emblems supported by the works of the historian Bronislaw Baczko and the anthropologist Michael Herzfeld’s. Throughout the paper, the theoretical aims are illustrated with reference to coal-mining memory and heritage in the north of France.
Bio-Somatic-Power
Authors: Tucker Ian
Published: February 2022

Biopower is a prominent force in mental health, with psychiatry having a strong influential grasp across the areas of definition of mental disorders, diagnosis, care, treatment, and legislation. One area that impacts upon the everyday lives of community mental health service users is treatment, largely dominated by medication. This paper will explore biopower in relation to the practices and management of mental health service users’ medication regimens. Michel Foucault’s insistence in his later work that power is the product of bodily forces will be drawn upon in highlighting the importance of undertaking analysis of medication regimens. Taking examples from a project focused on service user experience, the concept of ‘somatic enactment’ is suggested as a means through which to open up biopower to the localised concerns of service users with regard to the issue of managing one’s body on a day to day basis, as affected by medication. In doing so, the author seeks to move towards a notion of biopower that does not only work on a ‘top down’ manner, and in which processes of embodied subjectification can be illuminated, without recourse to a straightforward power-resistance framework.
The spatial anticipation of the future in the homes of mental health service users
Authors: Tucker Ian
Published: February 2022

This paper develops an approach to analysing the importance of anticipations of the future on present actions in the lives of mental health service users, for whom sensing stability in the future is important as part of the recovery process. The work of Henri Bergson and Alfred North Whitehead is drawn upon to argue that temporality is understood spatially, and that past and future experience only exist in relation to their shaping of present activity. This process is produced spatially rather than chronologically. Drawing on empirical work with community mental health service users the paper focuses on the home space as a key site for organising space in anticipation of future life. This involves analysing accounts of home making in which we see the role of anticipatory futures in the ordering of domestic space. The paper concludes by arguing that home spaces are a key site related to ongoing psychological well being, and that analysis of such spaces is important in terms of highlighting practices through which service users attempt to ‘make the future’.
“I would rather be hanged than agree with you!”: Collective Memory and the Definition of the Nation in Parliamentary Debates on Immigration
Authors: De Saint-Laurent Constance
Published: February 2022

This paper explores the meaning attributed to the national group as an entry point into how boundaries between the in-group and the out-group are formed. To do so, it focuses on the representation of the past of the group, taken as a symbolic resource able to produce a raison d’être for national groups, and does so within a dialogical framework. Using the transcripts of the French parliamentary debates on immigration from 2006, it proposes a qualitative analysis of collective narratives of the past along three axes: 1) what meaning do they give to the nation, 2) how is such a meaning produced, and 3) how do the stories told by different groups reply or relate to one another. By identifying the main narratives found in the data and how they relate to each other – within and between groups – it proposes to see collective memory as itself the product of symbolisation processes and, therefore, as a cultural tool especially powerful to produce meaning about the present. This paper also argues that collective memory is a situated construction negotiated with – or contested by – others, made possible by the presence of common historical benchmarks to which different meanings may however be attributed. Finally, it proposes to understand “immigration talk” as potentially the product of the identity questions faced by the national group, rather than the other way around.
Immersed In Pellet Technology: Motivation Paths of Innovative DIYers
Authors: Freeman Stephanie
Published: February 2022

What drives and moves an individual towards certain goals and activities is a familiar question for scholars dealing with motivation in the context of schooling or (techno-scientific) work practices. However, non-school contexts such as Internet-enabled volunteer-based technical DIY communities are also important to understand since a growing part of everyday social life is spent on the Internet. This article offers the analytical concept of 'motivation path' for understanding changing and dilemmatic motives in innovative pellet DIY development. It also introduces the concept of 'innovative DIY' to show the blurring of the boundaries between profession/hobby and  and past work life/retirement of technically competent, innovative people. The findings indicate that Internet-enabled making can be an important medium for continued personal growth, competence development, and (self) reflection. The findings could also help us understand how motivations may be carried over from professional work to private DIY work.
The Group as a Source of Development: Rethinking Professional Development in a Collaborative Perspective
Authors: Nasciutti Fabiana Marques Barbosa , Veresov Nikolai , De Aragão Ana Maria Falcão
Published: February 2022

Since the later decades of the 20th century, Brazilian psychologists have been questioning a theoretical and interventional model in educational contexts, which consider psychological phenomena apart from their cultural contexts, in order to develop an approach based on a contextualized viewpoint. Despite progress having been made in educational psychology, as a result of this critical paradigm, this area still has problems to overcome: Psychologists are becoming increasingly separate from schools, and it is now common to find psychologists who are professionally unprepared to perform in this context and furthermore, school principals do not always understand the role of psychologists in educational settings. However, educational demands exist in psychologists’ daily work in a range of contexts, indicating the relevance of this field and the urgency to improve psychologists' qualifications. Considering that Brazilian professional development programs for educators and psychologists are usually restricted to technical learning, often ignoring professionals’ real needs and claims, this research aimed to develop a special type of professional development program looking at the group as a source of development, in order to rethink professional development process from within a collaborative perspective. Research data was generated from a professional development program offered for psychologists and professionals who work within educational settings. This programme involved collaborative group work and was organized and conducted in such a way as to create conditions for change. Concepts of cultural-historical theory – social situation of development, crisis and perezhivanie – were used as analytic tools for data analysis. Analysis indicated the importance of the group as a source of development through dialogue and the co-construction of new ideas and possibilities.
Making of Wellbeing Measurement:
Authors: Simovska Venka , O'Toole Catriona
Published: February 2022

In this paper, we propose a ‘study protocol’ for researching the becomings of the Danish national wellbeing survey for schools. We engage with the idea of a published research protocol that originates from positivist research paradigms and medical research in particular. Within these paradigms, protocol serves the purpose of ensuring the objectivity and replicability of the research in question, and provides a sense of security to the researcher in terms of the quality of the research design. In contrast, with ideas of transmethodology in mind, we suggest a protocol that endeavours to support researchers to engage with ambiguity, uncertainty and singularity in research while still being attentive to quality. We suggest a protocol that helps de-stabilize the concept of wellbeing in schools and looks at how wellbeing as an object of measurement is (re)configured, who the human and non-human actors involved are, and what effects their assembling produces. These questions require research practices that acknowledge the complexities of the human condition and the richness of the social and material world. Instead of suggesting a “paradigm shift”, we are inspired by Patti Lather, who argues for a proliferation of paradigms, where proliferation refers to forming a pattern of interference. In other words, proliferation calls for reflection on the inconsistencies, confusion, disorganization of the research process, and both our need and caution to position ourselves epistemologically and ontologically. The protocol we suggest deploys diverse, sometimes complementary, sometimes contrasting methods, analytical strategies or theoretical perspectives in order to explore the problem at hand and engage with the ironies, tensions and uncertainties inherent to research.
Transformative expectations in research on environmental and sustainability education
Authors: Carlsson Monica
Published: February 2022

While education in general is seen as a crucial means for creating social change and transformation, environmental and sustainability education (ESE) is especially subject to transformative expectations in tackling escalating societal problems such as the lack of sustainable development. This article explores how ESE research addresses transformative expectations and justifies the knowledge it produces and its methods. It first explores examples of this within three different categories focusing on: transformative teaching in higher education, systemic transformative change in higher education institutions, and transformative change agency formation in community settings. Thereafter follows a discussion of the interfaces between the examples when it comes to their ontological, epistemological and methodological stances. The analysis illustrates different ways of conceptualizing transformative expectations, drawing on terms such as ‘rethinking’, ‘revitalizing’, ‘disrupting’, ‘reframing’ and ‘transgressing’. It furthermore highlights two different foundations for methodological justifications in ESE research addressing transformative expectations: working for change within existing social frameworks (adaptation), or seeking improvement by transgressing norms (disruption). It is pointing out that such methodological justifications are likely to differ in terms of how they address change depending on whether the research is conducted within or outside formal education settings.
Morphological Study of Left Ventricular False Tendons in Human Cadaveric Heart Specimens
Authors: Philip Shalom Elsy , Dakshayani KR
Published: February 2022

Introduction: Left Ventricular False Tendons (LVFT) is normal and common anatomical variants of the left ventricle. They may be associated with findings of cardiac pathology or they may be an isolated finding from 2D echocardiogram. These structures may mimic pathologic structures, such as intraventricular chorda rupture, vegetation or thrombus, but considered as false tendon. Aim: To study the morphology, age and gender specific proportions of false tendons in cadaveric heart specimens. Materials and Methods: A descriptive cross-sectional study was conducted in Mysore Medical College and Research Institute, Mysuru, Karnataka, India, from October 2015 to March 2017. A total of 100 human cadaveric heart specimens of both male and female (n=50) and female (n=50) aged 18-76 years were collected from Department of Anatomy and postmortem specimens from Department of Forensic Medicine. The morphology of tendons was studied regarding its location, gross appearance and parameters such as its length and width. The statistical analysis was done using Chi-square test and Analysis of Variance (ANOVA) test appropriately using the software Statistical Package for Social Service (SPSS), version 20.0 for windows. Results: False tendons were seen in 49 of heart specimens. Total 40 of the specimens showed one LVFT and nine showed two LVFT. Out of total 44 (58.67%) specimens aged 50 years or less had false tendons, while in older specimens, only 5 (20%) were found to have false tendon (p-value <0.05). The common location of false tendons was Posteromedial Papillary Muscle (PMPM) to mid interventricular septum 11 (18.9%), followed by PMPM to free wall 9 (15.5%). The tendons were fibrous in 53 (91.4%), fibromuscular in 4 (6.9%)and 1 (1.7%) was muscular in nature. Out of 50 female and 50 male heart specimens, 24 and 25 had LVFT, respectively (p-value=0.891). Conclusion: Sound knowledge of heart morphology can avoid false diagnosis in patients with false tendon, as it can simulate other pathological murmurs and structural heart disease in echocardiography.
Sports and Exercise Medicine in India: The Past and the Challenges
Authors: Sharma Hanjabam Barun
Published: February 2022

Sports and Exercise Medicine (SEM) started in India with Postgraduate (PG) Diploma in Sports Medicine (DSM) in 1986-87 and Doctor of Medicine (MD) more than two decades later. However, the concept of exercise is medicine can be traced back to the ancient Indus Valley civilisation. To fully develop and utilise this specialty, there is a need of continuously updating the current DSM and MD syllabus to world-class level, introduction of SEM into undergraduate curriculum, opening of SEM training-research institutes, recruitment of SEM-physicians as faculty and experts in various government and non government programmes and organisations dealing with various aspects of Sports Medicine (SM), Exercise Medicine (EM) and Sports and Exercise Sciences (SES). With only adequate development and growth of SEM and SES, will the dream of making India a fit, healthy and a world sports-giant be materialised. This review article has been compiled to provide information regarding SEM as a new medical specialty in India, its history and the current challenges.
Landscape Degradation Processes and Implications in the Western Highlands of Cameroon
Authors: Akhere Gwan Solange , Kimengsi Jude Ndzifon , Nji Fogwe Zephania
Published: February 2022

Globally landscape degradation has reignited renewed interest on the restoration of degraded landscapes across sub-Saharan Africa (SSA), including Cameroon. The aim of this article is to explore the processes and implications of landscape degradation in the south eastern part of the Western Highlands of Cameroon. Specifically, the paper sought to: (i) determine the triggers and pattern of landscape degradation, and (ii) analyse the socio-ecological effects of landscape degradation. The study employed a mixed-methods approach, involving a survey of 300 households, complemented by 7 focus group discussions and 22 key informant interviews to generate primary data. The data were analysed descriptively (using tables and charts) and inferentially using the binary logistic regression model. The results revealed that  population growth, poor farming methods and the expansion of settlement are the three major factors contributing to landscape degradation in the area. It further shows thatprior to settlement, most of the land was used for farming – this further justifies the fact that (poor) farming methods significantly trigger landscape degradation. Additionally,  landscape degradation has introduced significant effects in the western highlands to include the expensive use of soil additives, soil erosion and soil loss, the loss of soil fertility, among others.  Finally, and informed by the binary logistic regression, population characteristics strongly determine the spatial pattern of landscape degradation in the Western Highlands than topographic traits. This that farmers should be encouraged to engage in organic farming to promote landscape restoration. Furthermore, the practice of slash and burn and ankara should be strongly discouraged amongst farming groups.

Kingdom of Saudi Arabia (KSA) primarily relies depends mainly on groundwater for drinking and irrigation purposes. The study was therefore aimed to identify groundwater quality in Al-Jouf Region, KSA using water quality index (DWQI). In addition, investigating the hydro-chemical characteristics that control the groundwater quality. Groundwater samples were collected from 150 groundwater wells at a 300-500 m depth and subjected for chemical analysis. The values of chemical constituents were compared with the KSA and World Health Organization (WHO) standards for drinking and irrigation purposes. The results indicated that, the concentrations of ions were within the ranges of KSA for drinking water and WHO. Based on DWQI data, for drinking water about 23.9% of the wells were within poor water category (III), while 9.91% was very poor water within (IV) group, 45.6% is good water of group (II) and 20.5% is excellent water within category (I). Regarding the evaluation of water quality, the estimated DWQI values for the 150 well waters in Al-Jouf, region ranged from 40.7 to 319. About 23.9% of wells were considered poor water “class (III)”, 9.9% were very poor water “class (IV)”, 45.6% were good water for drinking or “class (II), and 20.53% were excellent water. The result shows that the groundwater possess moderate to high salinity hazards with low to medium sodium hazards. The piper diagram showed that cations were decreasing as follow: Na+>Ca2+>Mg2+, while the anions were decreasing as follow Cl− > HCO3− > SO42−>CO32-. The SAR values varied from 0.68 to 15.43; while Kelly’s ratio (KR) ranged between 0.32 to 4.02.

World agriculture is facing increasing demand due to multiple challenges. The biggest challenge is to attain food security in the ever increasing growing population. Rice (Oryza sativa L.) is a staple food crop for half of the world's population and one of the world's most significant food crops. Farmers must produce more rice with enhanced quality in order to ensure food security in rice-consuming countries across the world. Rice (Oryza sativa L.) is considered to be a Si accumulator plant and tends to actively accumulate Si into tissue up to concentrations of 5% or even higher. The present study aimed to use different forms of N and Si sources at different levels to improve the growth traits contributing to the increase yield of rice. A pot experiment was conducted in glasshouse, TNAU, Coimbatore to assess the response of nitrogen and silica on paddy during October 2020 – January, 2021. The treatments comprised of the two factors, nitrogen and silica with three replications. The growth parameters like plant height, number of tillers per plant and total dry matter production were recorded at all stages and yield traits at harvest stage. The treatment, T11 - N2S2 (53.4 and 110.2 g pot-1 respectively) significantly enhanced the grain yield (34%) and straw yield (40%) than control in the pot experiment. Highest growth and yield parameters were recorded with application of combined fertilization of nitrogen and silica (T11-N2S2) which comprises150 kg ha-1of urea and 200 kg ha-1 of calcium silicate compared to control.

The Villoglandular papillary adenocarcinoma (VGA) is a variant of adenocarcinoma of the cervix. It occurs in young women having a favorable prognosis. Pathologically, VGA poses a diagnostic challenge. Here we present a rare case of a middle-aged female patient complaining of bleeding per vagina since1year. Histopathological examination reported it as a well-differentiated villoglandular adenocarcinoma of the cervix. This tumor as a separate entity should be recognised, distinguished from other variants of adenocarcinomas. Because of its good behaviour and favourable prognosis usually itsallow conservative treatment.

Aims: The present study is aimed to develop watermelon seed nutribars (WMSNB) and to determine proximate content, antioxidant activity, free fatty composition and also sensory evaluation in order to create awareness of its potential nutritional values and increase its consumption in the form of nutraceuticals, functional foods and pharmaceuticals.

Study Design: Proximate analysis, total phenolic, antioxidant activity and free fatty acid profile was carried by using well established in-vitro assay.

Place and Duration of the Study: Department of Clinical Nutrition and Dietetics, Sri Devaraj Urs Academy of Higher Education and Research. Kolar, between June 2021 and November 2021

Methodology: The developed nutribars samples were evaluated for proximate analysis (moisture, crude protein, ash, total fat, crude fibre, and total carbohydrate), total phenolic, antioxidant activity by using DPPH assay, free fatty composition by using GC-MS, and sensory characteristics based on hedonic scale point. The ingredients used for preparation of WMSNB were Watermelon seeds (100gm), jaggery (50gm), coconut flakes (15gm), sesame seeds (10gm) and ghee (5gm). Peanut nutribars (PNB) were also developed by replacing Watermelon seeds (WMS) with peanuts which was used for comparison purpose.

Results: The proximate screening indicated that protein (15.72%) and carbohydrate content (52.49%) was high in WMSNB compared to PNB. The prepared WMSNB showed rich in phenolics and also possessed good antioxidant activity against DPPH. The free fatty acid composition showed that linolenic acid, stearic acid and lauric acid of oil extracted from WMSNB were 51.15%, 10.65% and 6.49% respectively, while oleic and palmitic acid extracted from PNB were 38.11% and 14.62% respectively. The overall sensory evaluation showed that there was no significant difference (P<0.05) between WMSNB and PNB.

Conclusion: The antioxidant capacity of the WMSNB constituent underlines the potential source of natural antioxidants and bioactive compounds for the therapeutic purposes.

Error tracking approach to discrete‐time adaptive iterative learning control against arbitrary initial perturbations
Authors: Sun Mingxuan , Zhan Yizhao , Li Wei , He Xiongxiong
Published: February 2022

Initial condition problem is crucial to a conventional iterative learning control (ILC) scheme, which steers the tracking error from arbitrary initial value to zero in the time steps equaling to the relative degree of the system undertaken. The implementation may be difficult, due to the practical limitation for the control amplitude. This paper presents an error‐tracking approach to discrete‐time adaptive ILC designs for tracking nonidentical tasks in the presence of initial repositioning errors, which may be quite large. A prototype iterative learning algorithm is derived for estimating the time‐varying unknowns, and the saturation is introduced for assuring the estimates to keep away from zero. A key technical lemma, tailored for the analysis purpose in the iteration domain, is presented and applied to analysis of the ILC scheme. The tracking performance of the closed‐loop system is evaluated and explored in detail. It is shown that the perfect tracking for the error between the tracking error and the desired error is achieved at every time instant, while the input and output signals remain bounded. By the simulation example, the proposed scheme is verified to be applicable to tracking tasks without restriction on initial repositioning.
