Geopolítica de un nuevo orden mundial: Carl Schmitt y las fronteras de la globalización
Authors: Yousef Sandoval Laila
Published: October 2022

All geopolitical change represents the creation of a new order and this entails the alteration of the spatial conditions and, therefore, the modification of the way of understanding borders. Carl Schmitt, especially in his last stage, aimed at delineating a new international configuration made up of large spaces (Grossräume), once the time of sovereignties typical of the Ius publicum europaeum was over. The goal of this study is to analizy to which extent and how Schmitt 's analytical tools around borders can be useful to understand the current state of globalization.

Todo cambio geopolítico representa la creación de un nuevo orden y ello conlleva la alteración de las condiciones espaciales y, por tanto, la modificación de la manera de entender las fronteras. Carl Schmitt, especialmente en su última etapa, apuntó al delineamiento de una nueva configuración internacional conformada por grandes espacios (Grossräume), una vez que el tiempo de las soberanías propias del Ius publicum europaeum había terminado. El objetivo de este estudio es analizar hasta qué punto y de qué manera las herramientas analíticas de Schmitt en torno a las fronteras pueden ser útiles para comprender el estado actual de la globalización.
Fronteras, propiedad e intrusión: libertarios e inmigración
Authors: Loewe Daniel
Published: October 2022

El artículo indaga la legitimidad libertaria de las fronteras estatales para excluir inmigrantes. Se sostiene que en estas teorías la legitimidad de las fronteras se construye mediante la legitimidad de la propiedad. El artículo analiza las teorías libertarias de Nozick y Steiner y argumenta contra la idea de que el derecho de propiedad libertario permite excluir en las fronteras y sostiene que las condiciones de legitimidad de la propiedad implican una potestad estatal reducida para controlar fronteras. Si bien en un mundo ideal las comunidades dispondrían del poder total para controlarlas, en nuestro mundo imperfecto los estados carecen de esa potestad.
Fronteras y discriminación en el sistema global
Authors: Di Castro Stringher Elisabetta
Published: October 2022

Las fronteras han experimentado grandes cambios ligados principalmente al desarrollo de la globalización, la desigualdad de sus beneficios y el aumento inédito de las migraciones y movilidad internacionales. Este artículo se centra en la discriminación como uno de los grandes desafíos de la sociedad democrática asociado a la resignificación de las fronteras. Frente a las graves desigualdades y exclusiones que atentan contra la libertad y dignidad de las personas, se reivindica a la política, en diversos ámbitos y escalas, como posibilidad de construir un mundo menos injusto y violento, dejando atrás la ley del más fuerte.
Pueblo, territorio y derechos. La legitimidad estatal ante las fronteras móviles
Authors: Ochoa Espejo Paulina
Published: October 2022

Traditionally, people, territory, and rights must align to justify state control. However, states have recently shifted their borders so that these three elements are decoupled. How should we understand state legitimacy then? This paper examines three contemporary responses to the phenomenon of shifting borders. First, sovereigntism seeks to stabilize the relation of people and territory, even if that requires limiting the scope of rights. Second, democratic cosmopolitanism tolerates shifts in territory, as long as the people and rights coincide. Finally, the Watershed Model keeps rights within the territory, but it accepts changes in the people, as it separates democratic governance and rights from a particular national identity. The paper argues that the Watershed Model can better respond to the challenges posed by human mobility in times of planetary crises.

Tradicionalmente, pueblo, territorio y derechos deben coincidir para justificar el control estatal. Sin embargo, los Estados han desplazado recientemente sus fronteras de modo que estos tres elementos se encuentran desacoplados. ¿Cómo debemos entender entonces la legitimidad del Estado? Este artículo examina tres respuestas contemporáneas al fenómeno del desplazamiento de las fronteras. En primer lugar, el soberanismo trata de estabilizar la relación entre pueblo y territorio, aunque para ello haya que limitar el alcance de los derechos. En segundo lugar, el cosmopolitismo democrático tolera los desplazamientos del territorio, siempre que pueblos y derechos coincidan. Por último, el modelo de la cuenca hidrográfica mantiene los derechos dentro del territorio, pero acepta cambios en el pueblo, ya que separa la gobernanza democrática y los derechos de una identidad nacional concreta. En el artículo se sostiene que el modelo de cuencas hidrográficas puede responder mejor a los retos que plantea la movilidad humana en tiempos de crisis planetaria.

Concepciones sobre la Historia del Arte en la formación didáctica inicial
Authors: López-Castelló Raúl
Published: October 2022

Este trabajo indaga de forma exploratoria en las concepciones de los/as estudiantes del Máster en Profesor/a de Educación Secundaria (Geografía e Historia) sobre la Historia del Arte y su enseñanza y aprendizaje. El principal objetivo es analizar dichas concepciones para caracterizar el conocimiento académico profesional previo de los/as participantes y ser el referente de partida en el proceso de formación inicial. Para ello, se ha diseñado y aplicado un cuestionario en el momento previo al desarrollo del módulo en la didáctica de esta materia. Los resultados muestran unas concepciones duales que en buena medida se mantienen cercanas a una concepción formalista-teleológica de la disciplina, con una finalidad eminentemente culturalista y con unas estrategias de enseñanza y aprendizaje enmarcadas en la transmisión de contenidos. La formación inicial docente debería partir de estas concepciones para su reestructuración, apostando por la alfabetización audiovisual crítica de la ciudadanía.
Cogotas I en la Campiña Madrileña: un análisis de la relación entre yacimientos y vías de paso
Authors: Polo Romero Luis Alberto , Morales Manzanares Diana
Published: October 2022

The study evaluates the role played by connectivity during the Late Bronze Age in the Madrid countryside through the relationship between the sites, the cattle trails and the LCP. The proposal is based on the measurement with geographic information systems of the distance and the existing relationship between Cogotas I sites and passageways as a key locational factor within the nuclear area. The results reveal less than 500 meters of distance from the sites to the optimal routes. Therefore, we can point to connectivity as a locational decision of the Late Bronze Age communities in the geographic space studied.

El texto evalúa el papel que juega la conectividad durante el Bronce final en la campiña madrileña a través de la relación de yacimientos de dicha cronología con las vías pecuarias y los modelos de acumulación de desplazamiento óptimo (MADO). La propuesta parte de la medición mediante sistemas de información geográfica de la distancia y la relación existente entre sitio de Cogotas I y vías de paso como un factor locacional clave dentro del área nuclear. Los resultados nos muestran un resultado de menos de 500 metros de distancia entre los yacimientos y vías óptimas. Por tanto, podemos señalar la conectividad como una decisión locacional de las comunidades del Bronce final en el espacio geográfico estudiado.
Arqueología experimental con fines de investigación en la reconstrucción de caballería feudal europea del siglo XI. El caballero normando
Authors: Español Solana Darío , Jiménez Martínez Laura , Moratona Martí Arnau
Published: October 2022

This paper proposes an investigation based on the experimental method to know what the material culture was like around the military chivalry of the 11th century (1020-1080), when this feudal institution appeared. The study reconstructs elements of civil and military use, and implements a process to learn how the cavalry acted in military operations, tactics and techniques, alluding to militar technology, war horsemanship, biomechanical conditioning factors and the limitations of the historical method to explain the chivalric phenomenon in its functional aspect. In the same way, it proposes an approach by which experimental archeology can be taken into account in educational budgets based on the results obtained.

Greece: The Myth of Krypho Scholeio [“Secret School”]. Issues of Historical Understanding and Historical Culture
Authors: Apostolidou Eleni
Published: October 2022

This is an analysis of fifty questionnaires given to first-year students of the Department of Primary Education of the University of Ioannina, on the subject of the ’Secret School’ (Krypho Scholeio), and focuses on issues of epistemology and historical culture (Grever & Adriaansen, 2017; Stathis, 2004). The research is supported by previous empirical research regarding the evaluation of conflicting historical narratives by pupils and students (Afandi & Baildon, 2015; Chapman, 2016). The findings favor the actual existence of the ’secret’ school while students/participants, when asked how they interpret the existence of different views on this issue, referred more to the existence of “bias” in relation to the past, and to a lesser extent, to different “perspectives”, representing different groups and interests, either in the past or the present.

La investigación se apoya en investigaciones empíricas previas sobre la evaluación de narrativas históricas conflictivas por parte de alumnos y estudiantes (Afandi & Baildon, 2015; Chapman, 2016). Los hallazgos favorecen la existencia real de la escuela 'secreta' mientras que los estudiantes/participantes, cuando se les preguntó cómo interpretan la existencia de diferentes puntos de vista sobre este tema, se refirieron más a la existencia de un "sesgo" en relación con el pasado, y a un menor medida, a diferentes “perspectivas”, que representan a diferentes grupos e intereses, ya sea en el pasado o en el presente.

Authors: Yu Ho Yeol , Ternes Neal , Ambs Claudia B. , Kim Sanghoon
Published: October 2022

Understanding fans’ perceived associations with their favorite teams is crucial for the successful management of sport teams. In the current study, team brand associations are measured as a reflective-formative construct to examine the role of the fan identification on the relationship between team brand associations and behavioral intentions. Data from professional soccer spectators (n = 101) were analyzed using PLS-SEM. The results indicated that the reflective-formative construct of team brand associations and fan identification influence behavioral intention, whilst fan identification was found to mediate the relationship between team brand associations and behavioral intentions. Managerial implications include strategic marketing how sport team managers can alter their team brand associations to foster the relationship between fans and teams.
Validating School Counselor Professional Identity: Response to “Suicide Intervention in Schools”
Authors: Gibson Donna
Published: October 2022

In response to the manuscript of “Suicide intervention in schools: If not school counselors, then who?” the roles and responsibilities of school counselors and educators are highlighted as to effective preparation for suicide intervention. Although preparation in training is needed due to the increasing rates of suicide in K-12 student populations, the professional identity development of school counselors is examined as it applies to the growing mental health needs in schools. Implications for counselor educators and school counselors in their responsibility for training and prioritizing needs to address are provided.
School Counselors’ Vital Role in Suicide Intervention: A Response to Gallo and Wachter Morris
Authors: Stone Carolyn
Published: October 2022

School counselors have a critically important role in suicide intervention, one that provides the greatest chance to ensure student safety. In this response article, I clarify the intent of the American School Counselor Association magazine column, "Suicide Assessments: The Medical Profession Affirms School Counselors’ Truth," to underscore the critical role that school counselors play in suicide intervention. School districts are requiring school counselors to quantify suicide and make a judgment based on the student’s self-report. The intended message of the column was not to diminish school counselor training in suicide assessment and intervention, instead it was to provide school counselors a tool in their advocacy efforts to move from district requirements to quantify suicide to the more powerful role of information gatherer. Working within this role, school counselors assist parents/guardians in seeking external counseling professionals who can provide tools not available in schools, such as family therapy, residential treatment, medication, hospitalization, treatment plans, and intensive therapy.
Struggles with Dramatic Form in 16th-Century English Biblical Plays
Authors: Matyjaszczyk Joanna
Published: October 2022

The aim of the article is to pinpoint how 16th-century biblical drama tried to appropriate its genre and medium to carry the reformist message and in what sense the project turned out to be a self-defeating one. The analysis of selected plays from reformed biblical cycles (The Chester Mystery Cycle, play iv; and “The Norwich Grocers’ Play”) and newly composed drama (John Bale’s plays, Lewis Wager’s Life and Repentaunce of Marie Magdalene, the anonymous “History of Jacob and Esau”), supported with an over- view of the criticism on the matter, reveals some common tensions in the dramatic texts which may have had their roots in the reformist need to eliminate any room for doubt that a theatrical performance could leave. The conclusion is that, in its attempts at striking the right balance between dramatizing and overt sermonizing, engaging and distancing, as well as providing an immersive experience and discouraging it, post-Reformation Scrip- ture-based drama oscillated between being more effective as a performance or as a carrier of the doctrinal message, with the resulting tendency to subvert either the former or the latter.
The Effect of Sterility Values and Retort Temperatures on the Change of Physical and Sensory Properties of a Canned Mushroom Product
Authors: Pursito Didik J. , Purnomo Eko , Fardiaz Dedi , Hariyadi Purwiyatno
Published: October 2022

This research aimed to study the effect of sterility values on physical quality (drained weight, brown colour index, and texture) and sensory properties of canned Agaricus bisporus mushrooms processed at different retort temperatures (115, 121, and 130 °C) and processing times (2-97 minutes). Mushrooms in brine solution media packaged in 300x407 cans were heated in industrial-scale horizontal static retorts at different retort temperatures for specific processing times to reach different F0-values. The canning process was carried out following commercial production procedures in one of the mushroom canning factories. Measurement of heat penetration into the product was carried out using a protocol established by the Institute of Thermal Process Specialists (IFTPS), and the sterility values (F0) were calculated. Our results indicated that the physical and sensory properties of canned mushrooms were not only affected by sterility value but also by the combination of temperature and time used to process the product. At the same level of sterility, a higher retort temperature (130 °C) resulted in canned mushroom with a lower browning rate, an improved texture profile (decreased hardness, increased chewiness, and shear force), a sweeter taste, and increased intensity of umami taste. However, the canning process at a temperature of 130 °C resulted in a greater reduction of the drained weight as compared to that of canning at 115 °C and 121 °C.
Development of High-Fiber, Low Fat Chicken Nuggets
Authors: Alrawashdeh Hamza , Abu-Alruz Khaled
Published: October 2022

Dietary fiber intake is significantly below the recommended daily allowances worldwide, making fortification of foods with dietary fiber a vital strategy. Simultaneously, there is a trend towards increased consumption of processed meat products containing substantial amounts of fat, making processed meat products an excellent vehicle to deliver fiber. In this study, the effects of adding four types of dietary fiber (Resistant Starch (RS), Polydextrose (POD), Fructooligosaccharides (FOS) and Galactooligosaccharides (GOS)) to chicken nuggets were investigated. Fibers were added at three levels (5, 10 and 15%) to replace 33.33, 66.66, and 100%, respectively, of the chicken skin. The difference between the removed quantity of chicken skin and added fiber was compensated with water. Chicken nuggets were evaluated by measuring color, texture, proximate composition, yield and consumers’ acceptability. Results indicated that replacement of the chicken skin entirely with dietary fiber is possible without negatively affecting the final product quality.

Authors: Mangku I Gede , Suriati Luh , Ardana Dewa Gede Yudi , Putra Wayan Widiantara
Published: October 2022

The coffee of Arabica Kintamani is one of the most popular coffees in the world due to its specific taste. The quality of coffee beans depends on the post-harvest and processing method. Dry processing and wet processing are the most popular methods used and each process produces different quality coffee beans. The objective of this research was to study and analyze various processing methods of coffee beans and to determine the best processing method to apply by the farmers and processors. This research consisted of three processing methods for the coffee namely dried processing (natural); wet processing; and semi-wet processing (honey). The research used a randomized complete design with one factor and five replications. The study showed that dry processing (natural) produced good quality coffee beans compared with wet or semi-wet processing, with significantly higher polyphenols content of 40.80 ± 0.053 mg GAE g−1 , approximately the same caffeine content (1.19 ± 0.016 %), significantly higher antioxidant activity (% DPPH) 89.53 ± 0.229 % with an EC50 equal to 102.44 ± 0.130 mg L−1 , similar lightness 13.63 ± 8.281 and a significantly lower moisture content of 7.54 ± 0.474 %. This indicated that dry processing could be used as an alternative processing method by farmers and processors due to it being easier, cheaper, with more efficient water use as well as giving a product contained the highest levels of polyphenols and antioxidant activity that are good for human health.

Authors: López Trullén David , Álvarez-Martínez José Manuel , Sánchez Labrador Jesús David , Jiménez-Alfaro Borja , Pérez-Silos Ignacio , Hernández-Romero Gonzalo , Barquín José
Published: October 2022

El seguimiento de la respuesta espectral obtenida por sensores remotos de media resolución relativo a formaciones vegetales puede proporcionar información muy relevante para el estudio de su distribución y dinámica a lo largo de gradientes ambientales y escalas geográficas. La combinación del ciclo orbital y el ancho de barrido de Sentinel 2 proporciona datos cada 5 días en latitudes medias, lo que permite realizar un seguimiento temporal de alta resolución relacionado con etapas o fases fenológicas de los ecosistemas en las que varían su composición, estructura o funcionamiento. En este contexto, el objetivo del presente estudio consiste en la obtención de curvas espectrofenológicas promedio para algunas de las principales formaciones arbóreas presentes en Cantabria, así como el análisis y la caracterización de métricas fenológicas espaciales que permitirán caracterizar el funcionamiento diferencial de la vegetación en el continuo del paisaje. Para la definición de las curvas se han empleado todos los datos históricos disponibles del sensor MSI, a bordo de los satélites Sentinel 2 A y B, con los que se ha generado una serie temporal de alta resolución del índice NDVI. Los datos se han agregado temporalmente a nivel mensual tras aplicar un filtro de nubes y sombras que maximiza la calidad del dato a nivel de pixel y un suavizado temporal de la serie para eliminar valores anómalos y perdidos. Los valores del índice han sido extraídos para una muestra de 230 puntos localizados con precisión GPS y cuya composición florística ha sido caracterizada por botánicos en campo. Se han obtenido curvas espectrofenológicas estacionales para los años del 2017 al 2020 y las curvas promedio anual, determinando su variabilidad y el grado de representatividad para las formaciones estudiadas. Finalmente se han obtenido las ecuaciones de las funciones ajustadas a las curvas promedio por formación vegetal aplicando análisis de Fourier. Los resultados muestran rasgos diferenciales para cada una de las tipologías forestales analizadas debido, principalmente, a la existencia de variaciones fenológicas intra e interanuales. Estos resultados demuestran el interés de emplear series temporales de datos para la determinación de curvas de referencia para diferentes tipologías forestales que permitan identificar su distribución espacial y otros rasgos relativos a su estructura y funcionamiento. Potencialmente, estas series de datos podrían ser utilizadas para la detección temprana de anomalías funcionales relacionadas con efectos derivados de perturbaciones naturales o antrópicas en un contexto de Cambio Global.

Authors: Verma Satyaveer , Bangarwa Nidhi , Ahlawat Geeta , Kamal Kirti
Published: October 2022

Introduction: Peripheral venous cannulation in the paediatric age group is always a challenging task. The transillumination technique improves the visualization of veins. The Light Emitting Diode (LED) vein finder device is based on the side transillumination principle. Aim: To evaluate the role of transilluminating LED vein finder device (Optramed Vein-Lite), for peripheral intravenous cannulation in children with respect to ease of cannulation, time taken and number of attempts. Materials and Methods: This randomised clinical study was conducted in Pandit Bhagwat Dayal Sharma Post Graduate Institute of Medical Sciences, Rohtak, Haryana, India, from January 2018 to January 2020. Total 130 patients, age <3 years, of either sex, and scheduled for surgery under general anaesthesia were included in the study. They were randomised into two groups. Group I (n=65) where venous cannulation was done using a transilluminating LED vein finder device, and group II (n=65) where venous cannulation was done after visualising and palpating the vein manually (conventional technique). Both the groups were compared with respect to the Difficult intravenous access (DIVA) score, number of attempts, ease of intravenous cannulation (cannulation on first or second attempt as ‘easy’, more than two attempts as ‘difficult’ cannulation) and time required for intravenous cannulation. The qualitative variables were expressed as frequencies/percentages and compared using the Chi-square test. A p-value <0.05 was considered statistically significant. Results: The mean age of the population in group I was 17±13 months, and in group II was 15±23 months (p-value=0.5427). There was a significant variation with respect to the number of attempts; the first attempt success was 90.7% in group I vs 63% in group II (p-value= 0.0014). In group I, cannulation was easy in 95% of patients while in group II only 76.9% of patients had easy cannulation (p-value=0.0018). Time taken for intravenous cannulation in group I was 19.385±6.2015 sec and in group II was 22.886±11.6716 sec (p-value=0.0346). Conclusion: Transillumination is a useful technique to improve the success rate of peripheral venous cannulation in infants and children.

ATR-FTIR, SAXS and UV-Vis Studies of Silicone Hydrogel and Bio-Hydrogel Soft Contact Lenses
Authors: Bayarı Sevgi , Göcen Tuğba , Bacıoğlu Akın , İde Semra
Published: October 2022

Aims: This study aimed to evaluate the effect of contact lens materials on the structural properties and to examine ultraviolet (UVA part) and visible (Vis) transmittance with and without UV filters of the commercially available silicone hydrogel (SiHy) and bio-hydrogel (bio-Hy) soft contact lenses (CLs) in vitro.

Place and Duration of Study: Hacettepe University, Department of Physics, Ankara, Turkey, between May 2018 and May 2021.

Methodology:Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) spectra of CLs were recorded (at removing from its package, after 10 min, 1 h and 1 day at room temperature) in the 4000-650 cm-1region  to  estimate water contents of CLs. Hierarchical Cluster Analysis (HCA) was performed to differentiate chemical structure of CLs based on the spectral differences. Ultraviolet (UVA) and visible light transmittance of (CLs) was measured in the 315 -800 nm region. Small Angle X-ray Scattering (SAXS) analyses were performed to obtain further structural information on nano-scale. 

Results: One of the key observations in this study is the large influence of lens water content. The HCA analysis grouped all the CLs of same  brand in same cluster based on their chemical similarity. The UVA transmittance results showed that CLs with UV blockers almost met ClassI and ClassII standards. The size (11.8-39.9 nm) and differences in morphologies of the nano globules were determined and correlated with equilibrium water content (EWC).

Conclusion: This work was designed to explain important characteristics of commercial CLs and results will have implications for future experimental and clinical research regarding hydration/ dehydration experiments with CL polymers.

Authors: Christophe Fopoussi Tuebue Jean
Published: October 2022

The aim of the present study was to highlight the impact of the interdisciplinary evaluation approach on the different actors around the ten schools selected all over the country for the experimentation of the concept. For that purpose, field and laboratory works were carried out. Many results were then collected. For all the 200 heads of Pedagogical Departments interviewed, this approach is the key that opens the way to permanent collaboration between the Pedagogical Departments of the same academic institution. All the 500 students interviewed up have noticed through this approach that all subjects are important despite some nuances noted within the comments of some. The heads of the ten establishments targeted across the country for this work have unanimously expressed positive judgments about this way of proceeding in an evaluation situation. In all ten Regions, seventy out of the hundred target families showed their enthusiasm directly after discovering the new configuration of evaluations in the institutions attended by their children. For the future, after two years, the approach should be applicable to the entire lower secondary cycle.
Numerical Simulation of Hygrothermomechanical Deformations of Bituminous Pavements in the City of Ouagadougou Subjected to Tropical Dry Showers
Authors: Koudougou Sidpouita Mathilde , Amadou Konfe , Toguyeni David Y. K. , Pantet Anne , Ouahbi Tariq
Published: October 2022

The waters of the torrential rains in the city of Ouagadougou lead to the appearance or amplification of damage to the surface of asphalt pavements during the rainy season. Road infrastructure maintenance campaigns follow one another almost every rainy season to fill potholes and cracks observed on the pavements. Several hypotheses can be put forward as to the origin of the action of water on the surface of pavements: the pressure of runoff water, infiltration, thermal expansion during the rainy episode, etc. These various reasons reveal the need to take rainwater into account when designing pavements. A previous study on the effect of heat waves on pavement design made some recommendations for better design. It has raised the interest to observe the impact of rain on pavement deformability.

The objective of this article is to estimate, as a first approach, the effect of tropical rains on the Thermomechanical behaviour of bituminous pavements formulated with pure grade 35/50 bitumen and grade 10/65 modified bitumen without trafic.

The properties of the road materials and the data from the statistical treatment of rainfall in the city of Ouagadougou were determined. The software based on the finite element method was used to model the phenomena coupling the meteorological conditions to the mechanical structure of the pavement for the quantification of hygrothermal and mechanical deformations.

The bituminous pavements studied were subjected to maximum rainfall intensities of 53.06 mm/h, and 99 mm/h with respective frequencies of occurrence of 2 years and 15 years.

The comparison of the temperature profiles at the surface of the studied pavements, allowed to highlight the viscous character of the asphalt subjected (35/50 bitumen and grade 10/65 modified bitumen) to the rains of maximum intensity of 99 mm/h. The maximum deformations simulated during these rains are about 1.2 times greater in the wearing course than in the base course, which does not disrupt the classical order of temperature evolution in the different pavement layers under dry tropical conditions. These deformations obtained also respect the admissibility criteria in terms of pavement design for T2 trafic (151 to 300 Heavy Truck/day). This study could be expanded to include the permeability of bituminous surfaces and runoff phenomena that could provide information on the origin of the observed deterioration.

A field experiment was carried out at the present experiment entitled “Productivity and profitability of sprouting broccoli (Brassica oleracea var. italica Plenck) under different major nutrient management with organic sources” was conducted at Vegetable farm, Chandra Shekhar Azad University Of Agriculture And Technology, Kanpur during rabi season 2021-22.The experiment consists of twenty-four treatment combinations of six sources of organic manure and four levels of major nutrients. The experiment was laid out in factorial RBD design and replicated three times. Palam samridhi variety of broccoli was transplanted at spacing of 45x45 cm. Results of the experiment revealed that the total head yield (q/ha) was significantly higher under M6 (FYM 20 t +Vermicompost 5 t  + Poultry manure  5 t  ha-1 ) source of manure which was at par application of M4 (Vermicompost 5 t ha-1) whereas in case of major nutrients it was significantly higher under application of (140:80:80 kg NPK ha-1) but it was at par with (120:60:60 kg NPK ha-1) and significantly superior to rest sources of organic manure. Maximum cost of cultivation, gross return as well as net return was associated with F3 (140:80:80 kg NPK ha-1) level of major nutrient but higher benefit cost ratio was noted under M3 (Poultry manure 5t/ha) source of manure and combination of M6 sources of manure along with F2 level of major nutrient fetches maximum net return of 9.71 which was followed by rest treatment combinations.

Authors: Rajendiran Prashanth , Saravanan Nithiyanandan , Ramamurthy Mageshbabu , Aruliah Rajasekar , Nandagopal Balaji
Published: October 2022

Introduction: The Rubella virus has a worldwide occurrence and congenital Rubella syndromes are widely recognized as an emerging infection in several parts of the world. Miscarriage, perinatal mortality, and stillbirth can develop in pregnancy during the first trimester. The most frequent techniques for laboratory diagnosis of Rubella virus infection are IgM and IgG-based serological detection methods. Such emerging viral and bacterial pathogen emphasizes the development of fast diagnostic devices; there is a need for enhanced and quicker methods.

Materials and Methods: Search for peptide vaccine with specific T and B-cell epitopes was identified through bioinformatics-based approaches. These were identified utilizing available Rubella virus E1 glycoprotein sequence databases. The outer-membrane glycoprotein, E1 is a target protein for the prediction of best antigens.

Results: Using BepiPred2 program, the potential B-cell epitope PFCNTPHGQLEVQVPPDPGD    with high conservation among E1 glycoprotein of rubella virus and the maximum surface exposed residues was identified.  Using IEDB, NetMHCpan, and NetCTL programs, T-cell epitope RPVALPRAL was identified. Predicted epitopes were found to have promiscuous class-I major histocompatibility complex binding affinity to major histocompatibility complex super types, antigenicity scores, and high proteasomal cleavage. The three-dimensional modeled structures were created using I-TASSER online server for highlighting the predicted T- and B- cell epitopes.

Authors: Antony Aneetta V. , Verma Ajay , Choudhary Udita , Sen Biswajit , Dixit Anil Kumar
Published: October 2022

Aim: The constraints involved in the adoption of clean and safe milk production practices were identified from a sample of 210 farmers covering three major districts of Kerala i.e. Kollam, Thiruvananthapuram, and Palakkad randomly. Average adoption score of 65 out of 95 practices indicated the need to sensitize the farmers for adoption of clean and safe milk production practices.

Methodology: The constraints faced by the farmers in adopting clean and safe milk production practices were identified and ranked using Garrett’s ranking technique. Kendall rank correlation was used to estimate the ordinal association of the ranks given to constraints by the farmers.

Results: Inadequate information about clean and safe milk production practices was identified to be the major constraint faced by the farmers followed by high cost of inputs, lack of finance, lack of infrastructure and constraints on the availability of land. Lack of finance, high cost of inputs and constraints on the availability of land were found to be strongly correlated to each other, having a cumulative adverse effect on the adoption of clean and safe milking practices.

The operation of power-generating plants becomes complex when two or more sources of power are combined. The decision of which source should take priority of load demand at various intervals requires sensitive control approaches. The Joseph Sarwuan Tarka University Makurdi (JOSTUM) 3.5 Mega Watts Solar Hybrid Power Plant (SHPP) has one source of renewable system; photovoltaic (PV) array, one source of energy storage system; battery banks, and one source of backup system; diesel generators (DGs), power conversion devices; Photovoltaic inverters (PVIs), power conditioning systems (PCSs) and switchgears were modelled and simulated. The   emphasis of the research is to obtain a control technique, which when applied to the PVI would improve the power produced from the PV array system. For a PV module to harvest the maximum amount of solar energy and simultaneously attain higher efficiency, PV systems must be operated at their maximum power point (MPP) under partially shaded conditions (PSC), varying irradiances and temperature. Maximum power point tracking (MPPT) methods are capable of guaranteeing MPP under varying climatic conditions. A control scheme is proposed using Whale Optimization Algorithm (WOA)-based MPPT control technique in order to improve the output power of the PV array. The output of the existing system from the PV array is about 1,800 kW, but when the WOA-based MPPT control technique is applied, an output of about 2,800 kW is produced. To validate the choice of the proposed technique, perturb and observe (P and O) algorithm for MPPT was tested on the system, which generated a mean power of 2,300 kW. The results proved that the proposed technique has an efficiency of 55.56% greater than the existing and P and O MPPT- based algorithm, which has 27.78%. The simulation was accomplished via MATLAB/Simulink.
Factors Determining the Formation of Toponyms of the Kola Peninsula
Authors: Sysolin M. , Kulakovskiy A.
Published: October 2022

A map of toponyms of the Kola Peninsula has been compiled and analyzed. The factors that determine the distribution and evolution in time of the areals of Russian, Finnish, Saami and Norwegian toponyms are:

Natural conditions and, above all, the distribution of rivers, lakes and mountain ranges that influenced the migration of peoples;

The specifics of the economic activity of the population: fishing, maritime trade, reindeer husbandry, industrial development of mineral deposits;

Political factors: changing state borders, attracting or vice versa expulsion of foreign colonists, forced Russification.

In the process of evolution, toponyms of different nationalities could interact with each other in different ways: somewhere “hybrid” Russian-Saami toponyms arose, somewhere Russian, Saami and Finnish toponyms turned out to be “mixed” and closely coexisted with each other, forming "integral" areals, and somewhere there was a complete replacement of toponyms of one nationality by toponyms of another.
Evaluation of Standard-of-Care Practices Among Physicians Who Treat Other Physicians
Authors: Avinger Anna McNair , McClary Tekiah , Dixon Margie , Pentz Rebecca D.
Published: October 2022

Importance

Ethical discussions have suggested that physicians who treat other physicians may put their physician-patients at risk of receiving non–standard-of-care treatment, which may result in worse outcomes. This phenomenon occurs when a physician treats a fellow physician as a VIP (very important person), and is therefore known as VIP syndrome. It is important to assess physicians’ perceptions when treating physician-patients.

Objective

To determine whether the physicians treating other physicians have attitudes toward or act in ways that could place physician-patients at risk for VIP syndrome.

Design, Setting, and Participants

This 2-part qualitative study was conducted from December 1, 2021, to February 28, 2022. Physicians who worked at a single comprehensive cancer center with experience treating other physicians were eligible to participate. Convenience sampling was used. Emails and flyers were sent out with study information, and if interested, physicians were able to schedule an interview. Of 24 physicians responding, 3 did not have experience treating other physicians, yielding a sample of 21 (88%), which was sufficient to reach a saturation of themes. After the initial structured interview of physicians, follow-up key informant interviews were performed.

Exposures

The structured interview was developed on the basis of a literature review and focused on factors that may contribute to VIP syndrome.

Main Outcomes and Measures

Participant responses to open-ended questions were qualitatively coded using standard multilevel semantic analysis to assess physician perceptions of treating fellow physicians. A series of Likert-scaled questions were used to identify potential contributing factors to VIP syndrome.

Results

Twenty-one physicians (11 men [52%], 11 White [52%], and 15 [71%] younger than 49 years) participated. Although no physician interviewed stated that they altered their usual treatment plans, 11 (52%) agreed that their physician-patients tried to dictate their own care, and 17 (81%) believed that their physician-patients obtained privileges, such as use of medical knowledge to participate in in-depth discussions of care, ability to obtain and use the treating physicians personal contact information, and receiving faster access to care. Eleven respondents (52%) reported increased stress, and 12 (57%) experienced more pressure not to disappoint their physician-patients.

Conclusions and Relevance

The findings of this qualitative study suggest that when physicians treat other physicians, the physician-patients may obtain privileges unavailable to patients who are not physicians. Therefore, guidelines to help physicians navigate the complex relationships between themselves and their physician-patients are needed to ensure equitable outcomes between physician and nonphysician patients.

Published: October 2022

Emergence of antibiotic‐resistance pathogens has caused serious health issues and if the current trend is to continue, treatment of the infection will become complicated and even unsuccessful due to new antimicrobial resistance (AMR). Therefore, there is a global drive to identify new methods to treat infection and develop better antibacterial materials and therapy. Although new and more potent antibiotics have aided the fight against microbes, they only offer a temporary solution because future bacteria strains may become resistant to these antibiotics and drugs. Recently, application of non‐biological methods such as, electrical currents and photothermal/dynamic therapies to kill bacteria, reveal new approaches to design antimicrobial biomaterials, as complications stemming from drug‐resistant bacteria can be obviated. Furthermore, recent research has focused on mimicking the surface patterns on plants and insects such as lotus leaves and dragonfly wings. Bio‐inspired micro/nano patterns have been replicated on a variety of biomaterials to improve the bacterial resistance and other properties with good success. This is an exciting research area with immense practical and clinical potentials. In this review, recent advances in the application of chemical/biological approaches to combat bacterial infection and AMR are summarized and the related mechanisms are discussed.
