Judeoconversas y élites dirigentes. Elvira González (†1463), origen postergado del linaje Arias Dávila
Authors: Contreras Jiménez María Eugenia
Published: July 2024

El artículo aborda a través de un estudio de caso el análisis de las mujeres judeoconversas castellanas que adquirieron relevancia histórica por su matrimonio con poderosos personajes. Elvira González (†1463), mujer de Diego Arias de Ávila, contador mayor de Castilla, ha sido estudiada a través de tres indicadores de una presencia y prestigio social en evolución: sus relaciones sociales, el espacio en que las desarrolló y los rituales funerarios seguidos en su óbito. Documentación de archivo, su epitafio sepulcral y textos histórico-literarios han descubierto su proceso de asimilación a progresivos estratos sociales y lo han hecho desde distintos intereses y miradas: la suya propia, la de su familia y las de terceros.

Authors: Kuhlmann Junior Moysés , Campos Alba Elida Lucila
Published: July 2024

Este artículo aborda la historiografía de la infancia y su educación en América Latina entre 1990 y 2020. Se toma como fuente principal la producción de libros, artículos y comunicaciones presentadas en las 14 reuniones del Congreso Iberoamericano de Historia de la Educación, organizado en torno a tres ejes: historiografía e infancia, política e instituciones, y sociedad y cultura. En el eje historiografía, se ofrece una descripción del marco que impulsó la investigación sobre la infancia a partir de la década de 1990, seguida de una discusión sobre la configuración del campo y los criterios de organización de los textos. En el segundo eje, se profundiza en el tema de la educación infantil en torno a cuatro subcategorías: pedagogía, políticas, instituciones educativas y biografías. En el análisis del eje sociedad y cultura, se hacen evidentes las diferencias que marcan las desigualdades sociales. Algunas cuestiones destacadas son: la necesidad de considerar el rango de edad utilizado en las investigaciones, la desproporción de estudios sobre la infancia entre los países latinoamericanos y el escaso número de investigaciones sobre niños menores de tres años. Finalmente, el artículo señala la necesidad de estudios que tengan en cuenta las estructuras políticas, culturales y sociales de cada período, investigaciones comparativas regionales e internacionales sobre la educación de la infancia, así como la formación de maestros, la educación de niñas y niños, y la posibilidad de dar voz a los niños para comprender las formas de apropiación y resistencia de las generaciones más jóvenes.
HISTORIA DE LA EDUCACIÓN DE NEGROS/AFRODESCENDIENTES E INDÍGENAS DESDE UNA PERSPECTIVA LATINOAMERICANA
Authors: Ocoró Loango Anny , Escalante Fernández Carlos
Published: July 2024

Este trabajo analiza cómo ha sido abordada la historia de la educación de los pueblos indígenas y de los negros/afrodescendientes en los Congresos Iberoamericanos de Historia de la Educación Latinoamericana (CIHELA) realizados entre 1992 y 2021. También explora algunos trabajos que, aun cuando no siempre están alojados o participan en los circuitos producidos por las redes académicas y asociaciones científicas, producen conocimiento que nutren el campo de la historia de la educación desde una perspectiva étnico-racial. Intenta responder a las siguientes preguntas: ¿cuáles son las principales tendencias temáticas y analíticas sobre la historia de la educación de los pueblos indígenas y negros/afrodescendientes en los estudios producidos en los últimos treinta años en el CIHELA, y en la literatura especializada que tiene lugar por fuera del Congreso? ¿Cuáles son las principales problemáticas que se estudian o privilegian? Finalmente, sostiene que el campo de estudios sobre historia de la educación de los y las afrodescendientes e indígenas al interior del CIHELA es emergente, dado que al interior del CIHELA no se ha desarrollado una tradición continua y son pocos los países que tienen una producción más permanente sobre el tema

Factors Influencing Low Muscle Strength among Community-Dwelling Older Adults with Non-Communicable Diseases
Authors: Whaikid Phatcharaphon , Aurmaor Thamakorn , Suvankereekhun Kanya
Published: July 2024

Introduction The presence of low muscle strength serves as a major indicator of sarcopenia and health status in older adults with non-communicable diseases (NCDs), leading to increased morbidity and mortality among them. 
Objective 1) To describe the prevalence of low muscle strength, and 2) To investigate personal and health factors predicting low muscle strength in community-dwelling older adults with NCDs 
Design This study employed a correlational predictive design, guided by physiological theory and literature as its conceptual framework. 
Methodology The participants consisted of 192 community-dwelling older adults diagnosed with non-communicable diseases in Samut Prakan province. Purposive sampling was employed according to the inclusion and exclusion criteria. Data were collected using the Global Physical Activity Questionnaire (GPAQ) version 2, the Thai Geriatric Depression Scale (TGDS-15), and nutritional and muscle strength assessments. Data were then analyzed using descriptive statistics and logistic regression analysis. 
Results Most of the participants were female (65.1%), with a mean age of 69.60 years (SD = 7.60). The prevalence of low muscle strength among older adults with non-communicable diseases was 54.17%. Personal and health factors including age (OR= 3.47, 95% CI = 1.91-6.33), weight loss (OR= 4.05, 95% CI = 1.11-14.70), physical activity (OR= 0.37, 95% CI = .19-.73), and depression (OR= 3.06, 95% CI = 1.16-8.03) were significantly predicted low muscle strength. Multiple logistic regression analysis revealed that age (OR= 3.02, 95%CI = 1.63-5.59) and physical activity (OR= 0.48, 95%CI = 0.24-0.97) together could predict low muscle strength among older adults with NCDs, accounting for 14.3% of the variance. 
Recommendation This study demonstrates that age and physical activity significantly predict low muscle strength among older adults with NCDs in the community. Therefore, health promotion programs addressing physical activity should be developed to reduce risk factors and to prevent and delay sarcopenia particularly in older adults of advanced age with NCDs.

Operating leverage: A critical analysis of the concept and the methods of measurement
Authors: Dudycz Tadeusz
Published: July 2024

Operating leverage is one of the more popular parameters used in management practice and scientific research. However, in the literature, there are many definitions and methods of measurement, which are additionally presented imprecisely in both textbooks and scientific publications. This results in a great deal of freedom among authors in the selection of measures for estimating operating leverage and the interpretation of the results, which has a negative impact on functionality for synthesis and theory building. Although some authors made such reservations clear as early as the 1980s, the situation has not changed. Using a three-step process of asking questions relating to how it looks, how it works, and how it compares to other “somethings”, the article conducts a critical analysis of the operational leverage measures used in recent publications and proposes to organize and refine the concept of operational leverage as leverage to increase value added and profit at a given output level using a trade-off mechanism between variable and fixed costs. Finally, the article suggests directions for future research and provides tips on how to incorporate the proposed concept of operating leverage into empirical research.

El apalancamiento operativo es uno de los parámetros más utilizados en la práctica de la gestión y la investigación científica. Sin embargo, en la bibliografía existen muchas definiciones y métodos de medición, que además se presentan de forma imprecisa tanto en los libros de texto como en las publicaciones científicas. Esto da lugar a una gran libertad entre los autores en la selección de medidas para estimar el apalancamiento operativo y la interpretación de los resultados, lo que repercute negativamente en la funcionalidad para la síntesis y la construcción de teorías. Aunque algunos autores ya pusieron de manifiesto estas reservas en los años ochenta, la situación no ha cambiado. Utilizando un proceso de tres pasos consistente en formular preguntas relativas a cómo se ve, cómo funciona y cómo se compara con otras "cosas", el artículo lleva a cabo un análisis crítico de las medidas de apalancamiento operativo utilizadas en publicaciones recientes y propone organizar y perfeccionar el concepto de apalancamiento operativo como apalancamiento para aumentar el valor añadido y el beneficio a un nivel de producción determinado utilizando un mecanismo de compensación entre costes variables y fijos. Por último, el artículo sugiere direcciones para futuras investigaciones y ofrece consejos sobre cómo incorporar el concepto propuesto de apalancamiento operativo a la investigación empírica.
URANIUM BEHAVIOR DURING THE FORMATION AND SUBSEQUENT STORAGE OF SOLID RADIOACTIVE WASTES FROM CONVERSION PRODUCTION
Authors: Skripchenko Sergey Yu. , Titova Svetlana M. , Nalivaiko Ksenia A. , Semenishchev Vladimir S.
Published: July 2024

A complex of physicochemical studies of solid radioactive wastes (RW) of the near-surface storage facility from conversion uranium production was carried out. It has been established that the composition of the wastes is represented mainly by calcium compounds: gypsum, calcite, and calcium fluoride. Uranium is distributed throughout the entire volume of wastes. At the same time, uranium is unevenly concentrated along the depth of the sludge. The content of uranium in the wastes is 0.005-0.65 wt. %. Uranium was predominantly adsorbed on the surface of sludge by main components during the formation of the wastes solid phase. Uranium was partially precipitated in the form of calcium-containing weeksite Ca2(UO2)2(Si2O5)3·10H2O, uranophane-alpha Ca(UO2)2(SiO3OH)2·5H2O, and urankalcarite Ca(UO2)3CO3(OH)6·3H2O. The isotopic composition of uranium contained in the storage wastes corresponds, within the error, to the normal isotopic composition of natural uranium. Near-surface storage is constantly exposed to natural factors. Infiltration of atmospheric condensation leads to leaching of some components from solid RW. At the same time, uranium goes into solution in the form of [(UO2)2CO3(OH)3]-, [UO2(CO3)2]2-, [UO2(CO3)3]4- and Ca2UO2(CO3)3. The subsequent migration of uranium with infiltrating water contributes to its distribution within the entire sludge field, including the reclamation soil layer and the near-surface pond. In some areas of the storage facility, the uranium content in the reclamation soil layer reaches 0.043 wt.%. The concentration of uranium in the pond was 17.97 mg L-1. The chemical composition of the pond water was characterized by a high content of chloride-ions (1.29 g L-1), calcium (630 mg L-1), sulfate-ions (224 mg L-1), hydrocarbonates (122 mg L-1). The pond is connected to groundwater, which increases the risk of pollutants escaping beyond the storage facility.

ASSESSMENT OF SPECIFIC SURFACE AREA AND POROSITY OF SUBSOILS
Authors: Asnin Leonid D. , Samoylov Mikhail S. , Pershina Margarita V. , Tselishchev Yurii G. , Sliusar Nataliya N.
Published: July 2024

Soils and subsoils have a complex structure consisting of several elements with different morphology and chemical composition, combining micro-, meso-, and macroporous substructures. Classical approaches, such as Brunauer-Emmett-Teller (BET) or Barrett-Joyner-Halenda (BJH) methods, cannot provide an accurate assessment of morphological characteristics of such solids, nor can do modern sophisticated numerical methods which depend on idealized models of pores that hardly reflect a real morphology of heterogeneous solids in question. The present study describes a way to overcome this difficulty by applying a combination of the αS-plot technique and a modified Remy-Poncelet method. The proposed approach allowed estimating the volumes of the untramicropores, supermicropores and the sum of meso- and macropores as well as the specific surface areas of the solid without ultramicropores and of the solid without all micropores. The former specific surface area is a more reasonable estimate of the area available for layer coverage than the BET specific surface area, and all together these characteristics provide a detail description of solid’s morphology. Subsoil samples excavated from different depths were used as exemplary solids. They mostly consisted of quartz, feldspar, and clay minerals and had different sorts of pores associated with the clay fraction and soil aggregates as well as a relatively large fraction of non-porous sand particles. Relations of the morphological properties with subsoil profile and mineralogical composition are discussed.

Variability and character association studies for horticultural and quality traits in garden pea (Pisum sativum L. var. hortense)
Authors: Devi Jyoti , Sanwal SK , Koley Tanmay K , Dubey RK , Singh PM , Singh B
Published: July 2024

The present study was conducted to examine the variability, heritability and correlation of important yield and quality traits and to determine the relative importance of primary and secondary traits as selection criteria to improve productivity in garden peas. Twenty-two diverse genotypes were grown in Randomized Complete Block Design with three replications during 2015-16. The data was collected on ten horticultural and four quality traits. Significant variations existed in all the traits. High value of PCV and GCV (e”20) were recorded for days to 50% flowering, plantheight, average pod weight, number of pod per plant, 100- green seed weight, green pod yield per plant and for quality traits viz., total phenolics contents, total flavonoids contents, CUPRAC and FRAP activities. This indicates that selection can be applied on the traits to isolate more promising line. High heritability (e”80%) and high genetic advance (e”50) were noticed for plant height, number of pod per plant, total phenolics contents, total flavonoids contents, CUPRAC and FRAP activities which indicated the role of additive gene action for the inheritance of these traits and are likely to respond better to selection. However, green pod yield per plant revealed moderate heritability and genetic advance. Correlation studies for green pod yield per plant showed a positive and significant correlation with days to 50% flowering, average pod weight and number of pod per plant suggesting improvement of yield by giving special focus to these traits. However, total phenolics and flavonoids contents were found negatively correlated with pod yield.

Heterosis breeding plays a major role in crop improvement for better yield and quality attributes. Cucumber, being monoecious and cross pollinated inn nature, contains more number of seeds per fruit and provides ample scope to harness hybrid vigour. Therefore, the present study was carried out to work out combining ability and heterosis for total soluble solids (oB) and seed traits viz., seed germination (%), seed vigour index-I and vigour index-II. The experimental material comprised of F1 and F2 population of 18 crosses,developed by crossing six lines and three testers. All thnine parents and their hybrids (18) indicated highly significant differences among the parents, F1’s and F2’s for all the traits studied. Experimental results revealed that parents viz., LC-1-1, LC-2-2, CGN-20515, Poinsette and K-75 and cross combination viz., LC-1-1 × K-75, LC-1-1 × Poinsette, LC-2-2 × K-75, LC-2-2 × Poinsette and CGN-20515 × Poinsette were found superior on the basis of overall performance and heterotic response (heterosis in F1 and residual heterosis in F2) for all the traits viz., TSS, seed germination and SVI-I and -II. These parents and hybrid combinations could be exploited commercially for the development of hybrids/ varieties for better TSS and seed trait in cucumber.

Evaluation of onion genotypes suitable for organic farming
Authors: Gupta Amar Jeet , Mahajan Vijay , Lawande KE
Published: July 2024

Organic farmers depend on varieties bred for conventional high-input farming systems. In north-western Europe, organic farmers are benefited from the improvements made by modern breeding activities. As organic farming refrains from high and chemical inputs, it needs reliable varieties better adapted to organic growing conditions to improve the yield stability and quality of crops. Thirty advance lines/ varieties of onion were screened to assess the suitability of cultivars under organic farming during late kharif at Kalus Farm of ICAR- Directorate of Onion and Garlic Research under short day conditions in comparison with in-organicconditions in respect of bulb yield and quality parameters. Based on two years mean data, maximum marketable yield was recorded in DOGR-1168 (47.59 t/ha) followed by EL- 1044 (45.44 t/ha) and DOGR-595 (45.35 t/ha) and these lines performed better under organic conditions. The performance of these lines under conventional in-organic trials were  comparatively poor and recorded 42.51 t/ha, 40.55 t/ha and 43.49 t/ha marketable yield, respectively. These lines also recorded more than 85% marketable yield, more than 95 g average bulb weight, less than 6% doubles and less than 10% bolters and were found highly suitable for organic farming.

Published: July 2024

An assessment of the competitive indices in intercropping between brinjal and palak was carried out with the aim of increasing the productivity of these crops as well as to achieve the optimum utilization of all the available resources. For this purpose, an experiment consisting of 11 treatments with three replications in a Randomized Block Design (RBD) was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during autumn-winter season of 2016-17. Intercropping systems were assessed by land equivalent ratio (LER), areatime equivalent ratio (ATER), relative crowding coefficient (K), aggressivity (A), competition ratio (CR), actual yield loss (AYL) and intercropping advantage (IA). Competition indices like CEY, LER, ATER and K were found to be superior for the paired row brinjal + palak (two rows). Although, the treatment brinjal + palak (three rows) was found better in terms of indices like A, CR, AYL and IA. This might be due to the interspecific and intraspecific competition between brinjal and palak for space, nutrients, light and availabl resources. LER, ATER and K values were greater than 1 for all the intercropping treatments. These findings showed a advantage of intercropping for exploiting the resources of the environment optimally.

Published: July 2024

Seventy melon genotypes, comprising of landraces, inbred lines and cultivars collected from diverse geographical locations, were evaluated for 17 morphological traits for determining the patterns of genetic diversity and relationship among genotypes. The genetic diversity based on quantitative and qualitative characters of genotypes was assessed by D2 analysis. The Euclidean’s distance-based clustering divided the germplasm in to nine clusters. Though the analysis of 17 descriptors distinctly separated momordica and wild accessions from cantalupensis, reticulatus, inodorus accessions, but it was not able to differentiate cantalupensis, reticulatus, inodorus group accessions. The inter-cluster distance varied from 759.6 between clusters 1 and 2 to 5194.5 between clusters 4 and 8. The maximum intra-cluster distance matrix was observed in cluster 9 (728.5), while cluster 6 exhibited the minimum intracluster variation (344.0). Maximum number of genotypes was grouped in cluster 1 and 7 i.e. 15 in each group. The genotype “Canary Yellow-2” present in cluster 4 did not grouped in any cluster. Overall, the clustering patterns exhibited great diversity in the germplasm for certain traits(fruit morphology and quality characteristics) which can be  utilized for broadening the genetic base of muskmelon germplasm and for developing specialty melon cultivars/ hybrids with unique traits such as high beta carotene, sweetness and extended shelf life.

Damping-off is a widely distributed and devastating disease causing severe seedling damage to nursery grown vegetable crops. The present study was undertaken to evaluate different doses of fosetyl-Al 80 WP against damping-off disease of tomato under field conditions in two consecutive seasons i.e., 2014-15 and 2015-16. The pooled data indicated that fosetyl-Al 80 WP @ 3g/l provided the best disease control (85.37%) amongst all the treatments against untreated control. In addition, it has increased the dry root mass and plant height by 39.1 and 64.86%, respectively above the untreated control. Application of fosetyl-Al 80 WP was not phytotoxic on tomato seedlings up to the dose of 12g/l.

Authors: Kumar Ramesh , Kumar Sandeep
Published: July 2024

The present investigation was carried out with the objective to standardize irrigation scheduling for improving capsicum yield for higher benefit: cost ratio under naturally ventilated polyhouse. The experiment was laid down in Randomized Complete Block Design (RCBD) along with seven treatments comprising of three irrigation depths, two intervals and a farmers practice. The data were recorded on days to first flowering, plant height (cm), days to marketable picking, total harvest duration (days), number of fruits per plant and yield (kg/m2). A perusal of the pooled data (2011 and 2012) revealed that different levels and frequencies of irrigationproduced significant differences with regards to different traits under study. The treatment with 0.25 cm irrigation at alternate day (T2) and farmer’s practice resulted in earliest flowering (41.71 days) and days to marketable picking (72.49 days), respectively. However, application of 0.50 cm of irrigation at alternate day (T4) resulted in maximum plant height (142.65 cm), total harvest duration (131.68 days), number of fruits per plant (18.26) and highest yield (12.76 kg/m2) along with maximum benefit: cost ratio (6.53:1). Hence,treatment T4 may be recommended for commercial cultivation of capsicum in the hilly regions of the country under naturally ventilated polyhouse.

Spring summer okra requires high and frequent applicationof water due to high evapo-transpiration demand. Deficitirrigation (supply less water than required) coupled withmulching is good agricultural practice to enhance water useefficiency in vegetable crops. In this study, three dripirrigation scheduling and two types mulches were evaluatedwith surface irrigation and without mulch. Maximum soilmoisture content of 12.2% and 13.5% was reported underorganic mulch, respectively at 20 and 30 cm depth. Plantsgrown under organic and black-silver mulch have registered52.5% and 35% higher chlorophyll content than control.Maximum stomatal conductance was reported with 100%PE + black-silver mulching (956.05 mmole/m2/sec).Significantly higher fruit yield (555.42 g/plant and 112.05 q/ha) was observed with drip irrigation at 100% PE, whereasin mulches, it was maximum under organic mulch (585.13 g/plant and 112.30 q/ha). As far as interaction of irrigation xmulch was concerned, the maximum yield of 684 g/plant and125.32 q/ha was reported with drip irrigation 100% PE +organic mulch, which was 64.8% higher in yield with 15.2%water saving than the control.

Published: July 2024

Extreme temperatures have always been a serious threat tobell pepper production owing to its heat sensitivity. Thepresent investigation was planned to assess the effect offoliar spray of growth regulators on morpho-physiologicaland yield parameters in bell pepper cv. Royal Wonder.Spraying bell pepper with Salicylic Acid (SA) and 24-Epibrassinolide (EBR) solutions significantly improved theirtolerance to subsequent high temperatures. Exogenousapplication of three different concentrations of growthregulators i.e SA (0.10 mM, 0.20 mM and 0.50 mM) and EBR(0.05 μM, 0.10 μM and 0.20 μM) were applied at followingstages; 30 days after transplantation (DAT), 60 DAT and 90DAT. These treatments helped in mitigating the heat stressby improving growth parameters (plant height, plant spreadand leaf area), photosynthetic efficiency, membranethermostability, pollen viability and fruit set percent even athigh temperature shows that application of PGRs definitelyplays a role in initiating various mechanisms involved inovercoming high temperature limitations. However, foliarapplication of 0.20 mM SA (30 DAT) followed by 0.10 μMEBR (60 DAT) significantly enhanced the growth and yieldparameters as compared to untreated control.
