The study was conducted during two consecutive years 2018–2019 and 2019–2020 at IARI, Regional Station, Pune, Maharashtra, India to evaluate for genetic variability, heritability and genetic advance of nineteen genotypes. Our objective was to select the promising genotypes under open condition with better horticultural attributes under Western Maharashtra plain zone. Based on average of two years data, total yield ranged from 1.79-4.22 t ha-1 and maximum observed in Orobelle Yellow. TSS ranged from 6.35–9.66°Brix, maximum in KTC-153 while Vitamin C content varied between 129.99–175.57 mg 100 g-1 FW maximum in ATS-89. Phenotypic coefficient of variation (PCV) was greater than genotypic coefficient of variation (GCV) for all traits. However, GCV values were near to PCV values for most of the characters indicating high contribution of genotypic effect for phenotypic expression. High heritability coupled with high genetic advance (Mean %) was obtained for plant height, number of fruits plant-1, yield plant-1, yield ha-1, fruit length, fruit diameter, fruit cavity, fruit weight, number of seeds per fruit, and hundred seed weight, reflecting the presence of additive gene effects for the expression of these traits. Genotypes NS-281, KTP-141, SH-SP-4-1, SH-SPH-603, ATS-89, ATS-86, KTC-153, ATS-86 were found promising in one or the other characters like number of fruits plant-1, yield plant-1, yield (t ha-1), Vitamin C content, TSS.

Using information technologies at all stages of patient care is necessary at the current state of medical development. It is particularly important to implement innovative information technologies in the management of patients with cardiovascular diseases in the outpatient setting, in secondary prevention and rehabilitation that continues throughout life. Various wearable devices for hemodynamic monitoring, electrocardiographic and physical activity assessment, that help the patient`s condition during rehabilitation, have been widely used in clinical practice all over the world. However, considering the outpatient setting, a cardiologist or rehabilitologist should to be able to monitor the data obtained using a single source, and to communicate with the patient in order to adjust treatment. Applications for mobile devices providing feedback can be a convenient tool in this regard. To date, many applications have been developed for smartphones, including those that synchronize with wearable devices, to record patient parameters, including the level of physical activity. Most of them are limited by self-control. Both in Russia and in other countries, a number of problems and limitations associated with the use of these technologies are related to the patient, the imperfection of the health care system, and problems with the devices themselves. The present article is devoted to an overview of existing remote rehabilitation technologies focusing on the applications for mobile devices. The authors present a short summary on domestic and international development in information technologies, identify the problems and future development of this area in health care.
Antigenic Activity of Canine Enteric Coronavirus Strain "Rich" in Experiments with Rabbits, Ferrets and Guinea Pigs
Authors: Komarova A. A. , Galkina T. S.
Published: January 2024

Introduction. Canine enteric coronavirus is a widespread infection, especially dangerous for the puppies of up to 12 weeks old kept in shelters and breeding kennels. The causative agent Alphacoronavirus 1 has a high mutational variability. Foreign sources have repeatedly reported on the isolation and study of the new strains of canine coronavirus infection, including the pantropic ones, causing systemic pathology and death of animals. In this regard, the currently produced vaccines are not effective enough. The present research is intended to substantiate one of the solutions to the problem. The aim of the work is to evaluate the antigenic potential of the canine enteric coronavirus strain “Rich” in terms of its reliability for being included in the combined vaccines against canine viral diseases.Materials and Methods. A purified suspension culture of the canine enteric coronavirus strain “Rich” with the infectivity titers 4.0±0.25 lg TCID50/cm3 (TCID — Tissue Culture Infectious Dose) was used in the work. Antigenic properties were studied in laboratory animals: rabbits, ferrets and guinea pigs. The virus neutralising antibody titers for the canine enteric coronavirus in the blood serum of the experimental animals was determined by a neutralisation test using the “standard” viral dose of 100 TCID50/cm3 in the feline kidney cell culture. The material for the test was obtained from the Cell Culture Bank of the Federal Centre for Animal Health.Results. In animals initially seronegative to the virus, an increase in the CCoV virus-neutralising antibodies (VNA) titers has been recorded 7 days after a single injection of the suspension of the canine enteric coronavirus strain “Rich”. Over the time, the level has been increasing and has reached its maximum value on the 21st day. The mean value in the group of rabbits has been 4.08±0.36 log2 SN50, ferrets — 3.72±0.35 log2 SN50 and 3.77±0.63 log2 SN50, guinea pigs — 4.12±0.34 log2 SN50. Then the values of the virus neutralising antibody titers have decreased, but remained at a fairly high level for 35 days (observation time). At the same time, the physiological state of the animals has not changed.Discussion and Conclusion. In general, the results of the experiments are consistent with the conclusions of the other authors. New data has been obtained by studying the antigenic properties of the strain in ferrets. The strain injected into them has demonstrated the clearly expressed antigenic activity and did not cause a general or local pathological response of the body. The “Rich” is promising for further study and can be included in the combined vaccines against canine and other animal viral diseases.

We started from the premise that developing pupils' ability to live with others facilitates the accelerated development of pupils' cultural competence. Therefore, interviews with school principals and online surveys were conducted for parents and teachers to make useful recommendations for teachers and school leaders. From the perspective of the management of educational activities, it is very important to strengthen the relations between the school and the members of the community. Also, the Erasmus+ and eTwinning projects play an extremely important role in the development of pupils' cultural competence. The study revealed the impact and benefits of establishing active partnerships between educational institutions and members of the local or international community. It is also recommended to develop educational projects through which pupils can come into contact with community members to better understand the historical past and cultural heritage of their country. The study is useful for school leaders and teachers interested in developing pupils' cultural competence.

In education, student involvement in writing activities is crucial for enhancing their learning experience and developing multiple competences. The development of any national curriculum within Europe is based on the indispensable competences required for lifelong learning as outlined in the European Parliament’s Reference Framework. In response to the changing landscape of education, the Romanian national curriculum has undergone revisions that currently prioritise a competence-based approach to teaching writing. This approach aims to equip students with the necessary skills and knowledge to effectively communicate through writing, enabling them to express their ideas and thoughts clearly and concisely. Nevertheless, it is noteworthy that there has been a lack of research conducted to assess the efficacy of the didactic resources and materials developed to facilitate these educational goals. This study uses corpus linguistics methodologies to examine the correlation between the content of textbooks used for writing tasks in primary education, secondary education, and high schools and the pedagogical skills they aim to develop. For this purpose, we have constructed a preliminary textbook corpus called ROTEX, which consists of online materials, specifically Romanian language and communication textbooks approved by the Ministry of Education. The corpus includes three datasets, one for each educational level (4th grade, 8th grade, and 12th grade). Our analysis uses writing tasks to identify linguistic and thematic complexity patterns. This approach allows us to determine the competences that are effectively enhanced at each educational level. Our conclusions are backed up by quantitative linguistic evidence, which provides valuable insights into the dominant competences fostered within the educational framework.

Impact of high-speed rail opening on the efficiency of enterprise human capital investment: Evidence from China
Authors: Cao Xuanze
Published: January 2024

In the current context of China’s vigorous development of its high-speed rail (HSR) network to accelerate the realization of connectivity, which is the aim of the “Belt and Road” initiative, it is crucial to study how the specific opening of HSR enhances enterprise human capital investment efficiency. Using a multiple-time-point difference-in-differences (DID) regression model, we empirically study data from listed Chinese companies. An HSR opening can promote the efficiency of an enterprise’s human capital investment. We further explore the relationship between HSR and a company’s human capital investment, by considering the moderating effects of firm property rights and foreign shareholding. Our findings indicate that these factors can enhance the impact of HSR on the efficiency of firms’ investments in human capital. Finally, to ensure the reliability of our experimental findings, we employed a combination of propensity score matching and the DID methodology. The findings of this study offer empirical evidence that can inform enterprise management strategies and provide valuable insights for policymakers seeking to promote economic growth.

Así mismo, se realiza un recorrido por las bases que anteceden al término de la proximidad, para revisar sus primeros acercamientos y conceptualizaciones, interpretándolo como uno de los medios para alcanzar el modelo de una ciudad compacta y sostenible de acuerdo con los ejes de análisis que se establecieron en la comparativa de los dos modelos de ciudad.
La crisis y recuperación social del entorno peatonal en las ciudades medias y superiores de México
Authors: Bureau Roquet Gustavo
Published: January 2024

La crisis de movilidad que aqueja a todas las ciudades medias y superiores ha invertido las formas de atender y resolver las demandas de traslado urbano, privilegiando el uso del automóvil particular por encima del derecho de movilidad del Peatón. El objetivo del presente documento es puntualizar los aspectos que conforman las condicionantes del Peatón, tanto como agente sustantivo de la movilidad urbana, como del entorno en que éste se desplaza. Lo anterior es con la pretensión de que dichas observaciones contribuyan a la revisión de los instrumentos normativos que en materia de movilidad existen, pero sobre todo, a que puedan incidir en la toma de conciencia social sobre el trascendente papel que juega la figura del peatón, a fin de que desde la misma base de la estructura social se asuman conductas resilientes que vayan modificando y trasformando, bajo una acción integral, las características del Entorno Peatonal a fin de hacerlo realmente operativo y pertinente.

El sábado 21 de marzo del año 2020 se estableció oficialmente la suspensión de actividades presenciales en la Universidad Veracruzana por la pandemia de COVID-19. La incertidumbre y el desconcierto ante un riesgo emergente y desconocido hizo de la tecnología un medio necesario para dar continuidad a la labor docente. Se expone en este artículo una metodología cíclica para la atención de experiencias educativas ante la posibilidad de emergencia, que puede ser pertinente en cualquier modalidad (virtual o presencial). Se establece como postura crítica que la brecha entre un suceso emergente y la programación académica tradicional debe ser reducida con prontitud y simplicidad, trabajando de manera asertiva en las habilidades que los estudiantes necesitan desarrollar. Este documento retrata tres experiencias educativas específicas, que fueron impartidas de manera virtual durante la pandemia y de forma presencial como parte de los primeros grupos piloto para un retorno seguro, lo cual permitirá al lector tener evidencias comparativas para poder sacar conclusiones respecto a las bondades o áreas de oportunidad de una u otra modalidad.

Actualmente, Zitácuaro no se utiliza para preservar el medio ambiente y el mal orden de residuos sólidos, rechazado por las áreas de producción que muestran lo más importante, responsable del deterioro del medio ambiente, al ver a las ciudades criticadas por los problemas creados por ellos, y especialmente por la contaminación del agua. Este proyecto ha tratado de desarrollar y preparar ladrillos con la adición de PET en forma de LEGO, utilizando materiales reciclados a partir de residuos sólidos creados en el mismo núcleo rural, donde se implementaba el entorno experimental del piloto, así como los desechos permanentes obtenidos en núcleos rurales investigados (botellas y otros desechos artificiales), los materiales necesarios como datos de entrada para la producción de ladrillos; Además, los materiales se pueden mezclar, la arena, el cemento, el agua y los animales se caracterizan por hacer una mezcla y construir patrones de ladrillo diseñados para desarrollar una solución alternativa para la reutilización. Y usar contenedores de plástico para reemplazar para restaurar el laboratorio para garantizar la venta de un nuevo producto estable con el material procesado que permite a las comunidades vivir en un futuro no fallado con armonía y con la naturaleza.

Un bloque de vidrio hecho a base de vidrio reciclado es una opción más amigable con el ambiente en mugar de un bloque de vidrio hecho con vidrio nuevo, pero agregándole nuevos componentes este podría ser altamente resistente, incluso podría soportar cargar similares a la que un ladrillo podría someterse. Como primer paso tenemos la recolección del vidrio para reutilizarse adquiriendo el material a los proveedores para su elaboración. Selección y clasificación: se tratará de clasificarlo por diferentes tonos o consistencia para poderlo llevar a la planta de producción y reutilizarlo para elaborar los ladrillos de vidrio. Después se fundirá el material para tener un mezclado de material, y así podremos cortar el vidrio necesario para la elaboración, se le dará forma por medio de un molde con la sección necesaria para las medidas dichas anteriormente, una vez después se podrá obtener la pieza desmoldada y se extraerá y enfriará la pieza.

One of the efforts that can be done is to increase the national corn productivity by developing prolific composite corn varieties. This is done because prolific corn is a type of corn with a tendency to produce two or more cobs, so that it can increase the value of corn production. The purpose of this study was to obtain prolific corn candidates (two cobs) with high yield and uniformity. This research was conducted using the mass selection method. Mass selection is done by selecting plants that have the desired character, namely prolific corn (cob two). The observed variables were the diversity in the F4 population, the percentage of prolific maize, and the comparison of the yield components of prolific maize with non-prolific maize. This study succeeded in obtaining 50% prolific corn on the cob and has wide diversity criteria. Of the 561 prolific corn plants, there are 91 corn plants that are classified as productive prolific. Prolific maize has a higher yield component than non-Prolific maize. Seed weight with cobs on productive prolific corn reached 318 g and seed weight reached 268 g.
Exploration and Morphological Characterization of Aren (Arenga pinnata Merr) Plants in Luhak District, 50 Kota Regency

Aren palm (Arenga pinnata Merr) belongs to the palm tribe. The problem that is often encountered in aren palm plants is the low productivity of aren palm plants, this is allegedly because the seeds used are not superior seeds and cultivation techniques that are not yet appropriate. The low production of plants is thought to be due to the low knowledge of the community on the use of superior aren palm planting materials, where the cultivated aren palm is not considered superior properties, including the diversity of aren palm species that grow wildly is still high in one forest land, unclear identity of seeds used by farmers. Exploration is the first step in finding germplasm of aren palm plants that have the expected traits through breeding programs so that it is expected to be one of the solutions for the development of aren palm plants. This research will be conducted from May to October 2023 in community-owned aren palm plantations in 50 cities. The purpose of this research is to characterize the morphology of Aren plants in District 50 Kota and to see the level of diversity of aren palm plants in the area. The research method was survey method, with purposive sampling. The data collection technique is to observe the morphological parts of the plant in each sample. The data obtained were analyzed descriptively, while for the analysis of similarity the calculation of the NTSYS Ver 2.02 program was used. The results of the study obtained 4 clusters of palm plants from 3 villages namely Nagari Sungai Kamuyang, Sikabu-kabu and Mungo. Researchers obtained 15 samples of aren palm plants characterized by 19 characters, namely 10 characters have wide variability and 9 characters have narrow variability with a level of diversity ranging from 14% - 47%.

Kebutuhan kedelai di Indonesia semakin meningkat seiring dengan pertumbuhan penduduk yang meningkat. Kebutuhan kedelai rata-rata mencapai 2,3 juta ton/ha, namun produksi di Indonesia hanya sekitar 800-900 ribu ton. Untuk itu salah satu upaya yang dapat dilakukan dalam meningkatkan produksi kedelai yaitu dengan menggunakan pupuk organik dengan kelebihan ramah lingkungan. Rumen sapi merupakan salah satu limbah yang dihasilkan dari rumah pemotongan hewan yang belum dimanfaatkan. Dalam rumen sapi mengandung banyak bakteri yang dapat dimanfaatkan sebagai bioaktivator. Bioaktivator rumen sapi dapat dimanfaatkan sebagai bahan untuk mempercepat proses dekomposisi pupuk kandang. Selain itu pada penelitian ini juga menggunakan limbah darah sapi yang berasal dari rumah pemotongan hewan. Rancangan yang digunakan yaitu Rancangan Acak Kelompok dengan satu faktor yaitu jenis pupuk kandang (A): A0 (Kontrol), A1 (pukan ayam + bioaktivator rumen), A2 (pukan kambing + bioaktivator rumen), A3 (pukan sapi + bioaktivator rumen) diulang sebanyak 4 kali. Hasil analisis data menggunakan Analisis Sidik Ragam dan apabila berbeda nyata dilakukan uji lanjut Duncan’s Multiple Range Test (DMRT) taraf 5%. Hasil menunjukkan bahwa pemberian pupuk kandang yang diperkaya bioaktivator rumen sapi berpengaruh nyata terhadap tinggi tanaman umur 28 hst, jumlah daun umur 14 hst, dan jumlah cabang umur 56 hst berat 100 biji tanaman, berpengaruh tidak nyata terhadap berat polong, dan jumlah polong cipo pertanaman pada tanaman kedelai (Glycine max L. Merril)
