Authors: Nikam D.R. , Pawar D.D.
Published: August 2022

Proper utilization and efficient development of the limited water resources is the milestone for food security for the entire world. Micro-irrigation technology facilitates improvement in water saving, water use efficiency, yield of the crop, investment in and short payback periods. The data was collected from 60 adopter and 60 non-adopter farmers of Dhule and Nandurbar districts of Maharashtra, India by personal interview through a pre-tested questionnaire. The constraints faced by the farmers in adoption of micro-irrigation technology were identified and put before the sample farmers and the farmers were asked to list priority-wise major constraints they were facing in micro-irrigation technology adoption for construction of a Responses-Priority Index (RPI). High initial investment of micro-irrigation system, clogging and chocking of emitters, unavailability of subsidy on time, lack of technical knowhow of micro- irrigation system and complex and lengthy procedure of loan were most perceived constraints with RPI values of 0.97, 0.90, 0.77, 0.70 and 0.68, respectively influenced the decision of micro-irrigation technology adoption.

Malnutrition is caused by the absence of any essential nutritional factor in the diet, including defects in the formation of hemoglobin or low absorption of essential nutrients. Some malnutrition due to lack of iron in the diet or high quality protein, vitamin B6 deficiency which affects the heme protein in the synthesis of hemoglobin, vitamin E deficiency which affects the stability of the membranes of red blood cells it happens. Copper is not part of the hemoglobin molecule but it affects the absorption of iron in the liver. Iron deficiency is the most common nutritional disorder in the world. Worldwide, anemia is estimated to affect 2 billion people, or 30 per cent of the world’s population and is more severe in developing countries due to frequent malaria and insect infestation. It particularly affects women in the reproductive age group and young children in tropical and sub-tropical regions. The World Bank estimates that malnutrition is a direct contributor to global diseases. Malnutrition occurs at all stages of life, but is most common in pregnant women, young children and teenage girls. Iron deficiency and malnutrition are a major public health problem among teenagers. Studies indicate that anemia in teenagers increases with age and the rate of growth is highest during teenage.

Published: August 2022

One of the most important aspects of agricultural production is soil fertility and nutrient management which has a direct impact on crop output and quality. However in the long run intensive cropping and chemical fertilizers harmed soil fertility and crop productivity by causing soil erosion, loss of top fertile soil, nutrient leaching, and uneven fertilizer use or little organic manure addition have resulted which caused human and animal suffering. To avoid nutrient mining and fertilizer imbalance, integrated nutrient management (INM) is a strategy for increasing agricultural productivity while also protecting the environment for future generations. It’s a method that uses both organic and inorganic plant nutrients to boost crop yield, reduce soil degradation, and satisfy future food supply demands. So INM is a vital aspect in achieving increased and long-term soil fertility and crop output. This study discusses the importance ofINM in wheat production in today’s intensive farming.

Significance Statement

Membranous nephropathy (MN) is an autoimmune disease caused by circulating antibodies, which target antigens on podocyte surfaces. We identified NTNG1 as a membrane protein that podocytes express and that circulating (mainly IgG4-subclass) autoantibodies target in patients with primary MN. Staining the target antigen in the biopsy and measuring circulating antibodies to determine the immunologic activity of disease provide a molecular characterization that improves diagnosis and clinical management of MN.

Background

Primary membranous nephropathy (MN) is caused by circulating autoantibodies binding to antigens on the podocyte surface. PLA2R1 is the main target antigen in 70%–80% of cases, but the pathogenesis is unresolved in 10%–15% of patients.

Methods

We used native western blotting to identify IgG4 autoantibodies, which bind an antigen endogenously expressed on podocyte membranes, in the serum of the index patient with MN. These IgG4 autoantibodies were used to immunoprecipitate the target antigen, and mass spectrometry was used to identify Netrin G1 (NTNG1). Using native western blot and ELISA, NTNG1 autoantibodies were analyzed in cohorts of 888 patients with MN or other glomerular diseases.

Results

NTNG1 was identified as a novel target antigen in MN. It is a membrane protein expressed in healthy podocytes. Immunohistochemistry confirmed granular NTNG1 positivity in subepithelial glomerular immune deposits. In prospective and retrospective MN cohorts, we identified three patients with NTNG1-associated MN who showed IgG4-dominant circulating NTNG1 autoantibodies, enhanced NTNG1 expression in the kidney, and glomerular IgG4 deposits. No NTNG1 autoantibodies were identified in 561 PLA2R1 autoantibodies–positive patients, 27 THSD7A autoantibodies–positive patients, and 77 patients with other glomerular diseases. In two patients with available follow-up of 2 and 4 years, both NTNG1 autoantibodies and proteinuria persisted.

Conclusions

NTNG1 expands the repertoire of target antigens in patients with MN. The clinical role of NTNG1 autoantibodies remains to be defined.

Abstract : Learning is a holistic process that involves several key components based on two-way interaction and transfer of knowledge between the learner and surroundings. Given the developments in technology and pandemic situation, finding the right mix of traditional and new learning styles is paramount. Traditional teaching and learning process have failed to create the necessary connect among the millennial learners. Therefore, a judicial use of traditional teaching techniques with the relevant technology will make for an effective tool in converting the millennial student into an active learner. Active learning approach is the first step in making learning an organic process. This approach will not only foster exchange of ideas among peers through discussions, case studies and role plays, but also cater to individual learning styles. The outcome of employing such an approach will promote higher order thinking skills, engaging in deep learning, and facilitate better transfer of knowledge. As there is no standard protocol to follow in technical higher education teaching, this concept paper is the first step in incorporating learner centric teaching that can bring better congruity and consistency in specific higher education fields.

Abstract : In this paper, the dynamic analysis of the dc-dc converter is proposed with an educational aid to ease the process in which the study is carried out. This study's primary importance is that it can be added to the curriculum of Master's program in Electrical Engineering. This article mainly focuses on the mathematical modelling of the dc-dc converter with which the dynamic analysis is carried out to regulate the load and line condition. The main problems in the analysis of higher-order dc-dc converter is addressed with techniques available in the literature. A quadratic boost converter with DCL cell is chosen for studying the dynamic analysis with the flow of the technique proposed. The solution to the resolvent matrix of the converter is obtained using Leverrier's algorithm. The higher-order system's transfer function is reduced using the pole clustering technique to ease the controller design. Finally, the PI controller is tuned with Ziegler-Nichols tuning and it is incorporated with the converter using the reduced-order transfer function. The input to output transfer function is analyzed with the step response in MATLAB software and compared with the full order transfer function to validate the reduced-order transfer function. The closed-loop response is also validated both with full order and reduced-order system.

Abstract: The social distancing policy as the basis for implementing learning from home makes it difficult for some teachers and students to adapt due to sudden changes. Online practicum learning at SMK is more challenging to implement. Students must possess the demands cognitive, affective, and psychomotor competencies. The main challenge for online learning in vocational education is how to expand traditional practice laboratories to the internet. This article synthesizes the study of virtual laboratories for online practicum learning. Articles published in the last five years are systemically reviewed. The existence of a laboratory that is fundamental to the experimentation of an object needs to be confirmed for its existence. Initially, virtual laboratories were developed to manipulate the presentation of difficult-to-handle materials in natural laboratories and abstract overview concepts. Opportunities to manage content that resembles actual conditions, visualization of complex materials, limited resources that can be overcome, personalization of learning, the minimal possibility of work accidents, the flexibility of time are the advantages of a virtual laboratory. Students are assumed to experience real-life education in the laboratory. Prepracticum demonstrations in natural laboratories provide an opportunity to increase the achievement of learning objectives. Types of virtual laboratories that can be developed in online practicum learning are video-based laboratories, web-based laboratories, and remote-based laboratories. With the existence of a comprehensive study, the research results can be a reference for the development of virtual laboratory media for vocational learning.

Abstract: The purpose of this study was to present learning the concept of electrolysis using simple copper media to vocational high school students in grade 3. This research was conducted by making a sample of well water with CuCl₂ solution which has a concentration of 1g / L and voltage variation (1.5; 3; 4.5; 6,0; 7.5; and 9,0 V). The test was carried out by electrolysis and water quality tests consisting of solute level testing, water pH test, and water temperature test. This research was also conducted by providing pre-test questions, learning videos, and post-tests. The results showed that the most effective electrolysis method occurred in variations with a voltage of 9V. This is indicated by the value of the decrease in concentration and the increase in mass of solutes after electrolysis. Meanwhile, the test results of vocational high school students show that video-based teaching can improve students 'understanding, as indicated by the students' post-test scores that are higher than the pretest scores. This research is expected to assist in the selection of instructional media for students and to find out which electrolysis method is effective for reducing Cu levels. Keywords: CuCl₂, electrolysis, learning media, simple copper.
‘Uncertain notice’: Unearthing Wales in William Wordsworth’s ‘Simon Lee’ and ‘Tintern Abbey’
Authors: Jones Matthew C.
Published: August 2022

One of the defining attributes of Wordsworth and Coleridge’s 1798 Lyrical Ballads was the poets’ focus on subjects of ‘low and rustic life’, and especially on the potentials for enhanced human understanding accessed through the language of people of such social stations. This essay examines Wordsworth’s ‘Simon Lee’ and ‘Tintern Abbey’, two entries set in Wales that in contrast to the collection’s manifesto do not feature the voices of the local inhabitants. Recent scholarship has effectively compounded the Welsh locals’ status: in addition to the comparatively little consideration given to the Welsh social history that would cover these topics, scholars have also at times re-set the poems in England, and even suggested that the Welsh inhabitants actually symbolise or otherwise represent English people. Minimising, disregarding, and altering the poems’ Welsh settings limits, and even misshapes, any meaningful poetic analysis. I argue that in each poem a deep understanding of the local cultural histories of the respective Welsh setting – Cardiganshire in ‘Simon Lee’ and Monmouthshire in ‘Tintern Abbey’ – produces a more comprehensive appreciation of the poems themselves. Furthermore, rather than acting as signs of a people unchanged since antiquity (another consensus among many literary scholars), these poems’ muted Welsh residents record the results of far-reaching social change, specifically the loss of traditions, community life, and economic stability. Such an approach enhances our understanding of wider contexts, including: Wordsworth’s authorship; Romantic Wales; the Welsh in the English imagination; and eighteenth-century Wales. I demonstrate these points by incorporating primary materials to complement my accounts of each poem, including contemporary histories of Cardiganshire in my examination of ‘Simon Lee’, and English poems of the period on Tintern Abbey and Monmouthshire in my examination of ‘Tintern Abbey’.

Authors: KESKİN İnan , KARATAŞ Fatih , KAHRAMAN Selman
Published: August 2022

In this study, the design of safe slopes was investigated, which is one of the main topics in geotechnical engineering. Another factor that should be considered in the design of safe slopes is seismic loads in addition to static loads. As part of the study, a series of slope stability analyzes were performed using finite element software by applying earthquakes with different characteristics to the model slope, which was designed with the intention of investigating slope behavior under seismic loads. The model slope designed in this context was analyzed with 12 real earthquake record data that occurred in different regions with different scenarios and had many station measurements. As a result, the effects of these earthquakes on the stability of the designed model slope were pointed out and the points that should be considered to obtain safer and more economical results in slope design in the direction of the obtained data.

Authors: not provided erika.laraflores
Published: August 2022

Induced pluripotent stem cell (iPSC)-derived neurons are an important tool for studying diverse types of neurodegenerative disorders, including Alzheimer’s Disease, Parkinson’s disease, and related dementias. Understanding the molecular and cellular mechanisms associated with these diseases is an important step in developing new therapeutic targets. Here we describe a robust differentiation protocol in which we expressed the human neurogenin 2 (NGN2) transcription factor under a tetracycline-inducible promoter as previously described (Fernandopulle et al. 2018), with several modifications and using a PiggyBac system for delivery. This differentiation protocol yields high percentages of cortical neuron markers.

ACE-inhibitory activity assay: IC50 v1
Authors: Coscueta Ezequiel
Published: August 2022

This protocol describes the procedure for the determination of the IC50 in inhibition on angiotensin-I converting enzyme (ACE) activity. ACE is also known as peptidyl dipeptidase A because it removes C-terminal dipeptides from a wide variety of peptide substrates. In the assay described here, the chosen substrate is the intramolecularly quenched fluorescent tripeptide o-aminobenzoylglycyl-p-nitrophenylalanylproline (Abz–Gly–Phe(NO2)–Pro). Hydrolysis of this substrate by the action of ACE generates the fluorescent product o-aminobenzoylglycine (Abz–Gly).

Authors: Álvarez-Arango Bryan , González-Medina Andrea , Valencia-Valencia Sebastián , Tamayo-Aristizábal Yessica Andrea , Pantoja-Rojas Danny Steven , Vélez-Puerta Karen Alejandra
Published: August 2022

Introducción: el destete ventilatorio (weaning) y la extubación en el paciente con lesiones encefálicas agudas es un desafío para el personal de salud ya que no hay un consenso claro sobre los criterios de extubación.

Objetivo: resumir la evidencia disponible sobre la extubación del paciente con lesiones encefálicas agudas y analizar posibles alternativas a los criterios clásicos de extubación.

Métodos: se realizó una búsqueda de la literatura médica, en los idiomas español e inglés, de los últimos 20 años en diferentes bases de datos. Se incluyeron revisiones sistemáticas con o sin metaanálisis, guías y recomendaciones de sociedades científicas, ensayos clínicos y estudios observacionales que cumplieran los criterios de inclusión.

Resultados: se recolectaron 262 artículos de interés, de los cuales, mediante un análisis y comparación de la evidencia, se seleccionaron 48 artículos que tuvieron más relevancia para cumplir el objetivo planteado.

Conclusiones: la evidencia disponible es débil a la hora de brindar una recomendación sobre los criterios de extubación en el paciente neurocrítico. Podría realizarse una extubación precoz con un nivel mínimo de conciencia, pero manteniendo los reflejos protectores de las vías respiratorias, sin tener aumento en la tasa de reintubación o mortalidad.

Published: August 2022

Introducción: tras la pandemia del COVID-19 y los casos de escasez de equipo de protección personal (EPP) se ha documentado el uso de máscaras de snorkel modificadas, buscando brindar protección respiratoria y facial contra los aerosoles del SARS-CoV-2. Sin embargo, no hay reportes de cambios clínicos que puedan ocurrir en el usuario, además de la percepción de usabilidad por parte de los trabajadores de salud.
Métodos: serie de casos. Equipo: snorkel mask®, adaptador 3D y filtro antimicrobiano. Se controló el nivel de CO2, la frecuencia respiratoria, la oximetría, el pulso y la presión arterial por una hora. Durante este tiempo se simularon actividades relacionadas con la atención al paciente. Al final se evaluaron las características de uso a través de una encuesta.
Resultados: se incluyeron 14 voluntarios. Después de una hora de uso continuo, los parámetros clínicos fueron predominantemente normales. El 85 % de los participantes prefirió esta máscara de snorkel modificada en lugar del equipo de protección personal establecido para COVID-19 (gafas, máscara N95 y visera).
Conclusiones: la máscara de snorkel adaptada podría ser una alternativa como EPP en situaciones de escasez de recursos. Lo anterior solo se considera en el marco de su aceptabilidad por un grupo de profesionales de la salud, además de la poca afectación en sus constantes vitales evaluadas en esta serie de casos. Se requiere evaluaciones más objetivas de usabilidad y efectividad.

Published: August 2022

Antecedentes: el etiquetado nutricional permite a los consumidores tomar mejores decisiones sobre alimentación, lo que contribuye a combatir las enfermedades crónicas no transmisibles. Objetivo: determinar cómo influye la interpretación del etiquetado nutricional, presente en los alimentos industrializados en Colombia, en la decisión de compra de estudiantes de pregrado del área de la salud de la Universidad CES. Materiales y métodos: se realizó un estudio observacional descriptivo en 76 estudiantes de quinto semestre de programas de pregrado del área de la salud. Resultados: la frecuencia en el uso del etiquetado nutricional se asoció con el sexo (p = 0,036), el tipo de programa (p < 0,001) y el conocimiento de la función del etiquetado nutricional (p = 0,000). La buena interpretación del etiquetado nutricional no condicionó la frecuencia en su uso (p = 0,095); además, el nivel de interpretación del etiquetado nutricional no se asoció con el sexo ni con el tipo de programa de pregrado. Finalmente, se encontró que la decisión de compra estaba influenciada por la costumbre (p = 0,018) y la publicidad (p = 0,008) y no por la interpretación del etiquetado nutricional. Conclusiones: aunque el uso del etiquetado nutricional es más frecuente entre las mujeres, los estudiantes de Nutrición y Dietética y entre quienes conocen la función del etiquetado nutricional, la decisión de compra no está influenciada por su interpretación.

Antecedentes: la pandemia y el confinamiento por COVID-19 modificaron las condiciones de vida de los escolares y sus familias. Objetivo: describir la ejecución de una intervención educativa alimentaria en escolares de la Institución Educativa Monseñor Gerardo Valencia Cano, Medellín, Colombia, antes y durante el confinamiento por COVID-19. Materiales y métodos: investigación cualitativa con apoyo de variables cuantitativas. La recolección y análisis de datos se hicieron con base en la teoría fundamentada. La población estuvo conformada por escolares y padres de familia de la Institución Educativa Monseñor Gerardo Valencia Cano. Antes de la COVID-19 se realizaron cuatro grupos focales y una encuesta semiestructurada a 416 estudiantes y sus padres de familia, y con 42 docentes se realizaron cuatro grupos focales más; estos se realizaron hasta alcanzar la saturación. Durante el confinamiento se aplicaron 237 encuestas a familias (escolares y padres). Se evaluó el estado nutricional. Resultados: el 37 % de los escolares entre tercero y séptimo grado tenía exceso de peso. Se logró identificar de manera participativa los factores de riesgo y protectores frente al exceso de peso, para definir una intervención educativa alimentaria desde y con los sujetos. Los nodos conceptuales de la intervención fueron alimentación saludable, métodos de cocción, preparación de alimentos saludables y alimentación para la prevención del exceso de peso y cáncer de colon. Conclusiones: el reconocimiento de las condiciones alimentarias antes y después del confinamiento de los escolares y sus familias, o del cambio de estas a lo largo de la intervención educativa, contribuyó a lograr coherencia entre las necesidades, objetivos educativos y metodologías implementadas. El hecho de tener reunidos en un mismo espacio (hogar) a los escolares y sus padres durante el confinamiento propició un microentorno favorecedor de conductas que motivaron una mejora de los hábitos alimentarios familiares.

Weak Predictability of Rupture Growth Evidenced by P Waves: Implications for Earthquake Early Warning

Published: August 2022

The time-evolving growth behavior during the early phase of an earthquake rupture and when distinguishable features arise for events of different sizes are critical issues for real-time seismology. These issues are related to the key concept of rupture predictability, which directly determines the warning time and the potential of earthquake early warning systems. P waves carry the temporal information of rupture development, which provides us with an important clue to investigate and understand the source physical process in the early stage of the rupture. In this article, for 36 shallow, moderate- to large-magnitude earthquakes (5.0≤Mw≤9.1) that occurred in Japan and China, we systematically assess and quantify the temporal evolution of the P-wave velocity amplitude (V-env) and the characteristic period (τc). The initial growth rate and the secondary evolution parameters are extracted to investigate the main features of the early rupture behavior. Our results show that the V-env exhibits distinguishable growth features after a similar steep rise affected by propagation attenuation for earthquakes of different sizes. Near the distinguishable points, the bell-shaped fluctuations are generally observed in the τc curves, and the fluctuation amplitude is positively correlated with the final magnitude. The distinct evolution of P waves radiated from earthquakes of different magnitudes occurs earlier than one-half of the rupture duration, which constitutes new evidence supporting the weak predictability of ruptures. Finally, we discuss the implications for the physical source mechanism and earthquake early warning.
High-Resolution Marine Seismic Imaging of the Seattle Fault Zone: Near-Surface Insights into Fault Zone Geometry, Quaternary Deformation, and Long-Term Evolution

The Seattle fault zone (SFZ) is a north-directed thrust fault system that underlies the greater Seattle metropolitan area. Evidence of past land level changes, landslides, liquefaction, and a local tsunami indicate that this 70-km-long fault system can host up to M 7–7.5 earthquakes. Both the geometry and earthquake recurrence of the SFZ are debated and surveys of the shallow subsurface have not yet been incorporated into deeper crustal-scale structural interpretations, especially where the SFZ cuts across marine portions of the Puget Lowland. Here we use a new high-resolution marine seismic reflection dataset to image fault-related deformation in Quaternary sediments and Tertiary bedrock throughout Puget Sound and Lake Washington. We use this perspective of shallow geology as a link between existing crustal-scale geophysical insights into fault geometry at depth and paleoseismological observations of faulting at the surface and propose a refined structural model for the SFZ. We interpret that our new seismic reflection data in the Rich Passage area of Puget Sound images evidence of an inactive, south-dipping strand of the SFZ, which is overprinted by Quaternary folding and slip along north-dipping backthrusts within the hanging wall of a blind, south-dipping fault located 6 km farther north. To explain these results, we propose that the SFZ is a normal sequence fault propagation fold that has stepped northward through time, and we show the plausibility of this model through trishear forward modeling. Growth strata and faulting imaged in Quaternary sediments in Lake Washington and Rich Passage are consistent with the spatial distribution of folding and backthrusting that occurred during an M 7–7.5 earthquake in A.D. 900–930, corroborating existing evidence that the SFZ has been active throughout the Quaternary.
A 1D Spring-Slider Model with a Simple Poly-Linear Failure Law Produces Rich Variations in Slip Behavior

Published: August 2022

The failure law prescribed along the fault surface and the elastic stiffness of the surrounding medium play important roles in determining the characteristics of earthquakes. Here we use a 1D spring-slider model that includes inertia, along with a simple poly-linear failure law composed of multiple linear segments to provide insight into earthquake initiation and growth. The poly-linear failure law, which parameterizes shear resistance as a function of slip, allows analytical solutions describing the system for each failure law segment. Analytical solutions facilitate investigation of the effects of the slopes of the different failure law segments in relation to the slope of the elastic loading curve determined by the spring stiffness. Depending on the relation between the slope of the failure law segment and the elastic loading slope, there are three stability regimes in the system: harmonic oscillations, exponential growth, and cubic growth. By combining the different solution regimes within one earthquake cycle, we observe a wide range of behaviors of this simple system: interseismic oscillatory creep, precursory signals before the main event, a shorter or a much longer acceleration phase before the onset of instability, and varying durations of the preseismic and coseismic phases. These results provide a potential explanation for some seismic observations, including increased levels of “seismic noise” prior to an earthquake, precursory events, tremor and low-frequency earthquakes.
Mikhail Bakhtin

O objetivo deste artigo é investigar como os temas do riso, da crise e da mudança orientam a teoria dos gêneros do discurso e, em particular, do gênero romance na obra de Mikhail Bakhtin, tomando como pano de fundo A poética de Aristóteles e os Cursos de estética (2014[1842]) de Georg Hegel. A pesquisa é de caráter bibliográfico e faz uso do estenograma de defesa de tese, das teses de duas apresentações orais, de cartas, de parte da produção bibliográfica de M. Bakhtin compreendida entre o final dos anos 1920 e 1960 e de obras de comentadores. Descobrimos que M. Bakhtin situa o romance e a representação da palavra nele em um momento de mudanças e crises nas línguas europeias e na vida discursiva dos povos, ao mesmo tempo que esse gênero desestabiliza os sistemas poéticos estabelecidos. A teoria dos gêneros de Bakhtin desenvolve-se em um diálogo tenso entre o passado literário concluso e a contemporaneidade extraliterária e literária em crise e formação.
