Published: December 2023

El objetivo de este artículo es mostrar y exponer a través de una narración cómo se construye la cooperación en un equipo y cómo sus miembros son los responsables de edificar una idea de lo que significa formar parte de un equipo. En el estudio abordamos la cuestión de la cooperación des de un enfoque constructivista que entiende el conocimiento como un proceso de construcción genuino del sujeto. La cooperación es definida como una habilidad comunicativa que permite a los miembros de un grupo construirse la idea de equipo y el aprendizaje cooperativo es la estrategia didáctica que utilizan los profesores para que surja la cooperación.La experiencia práctica se llevó a cabo con un equipo de siete alumnos que impartían una asignatura universitaria llamada Trabajo en equipo a través del baloncesto. Acorde con el paradigma de investigación constructivista se pidió a una estudiante que realizara un análisis narrativo de lo que había pasado en su equipo y escribiera una autobiografía. Los resultados del estudio se presentan en formato narrativo y en el relato la estudiante muestra la importancia de la responsabilidad personal, la interdependencia positiva y la valoración del equipo para construir el equipo. En las conclusiones se resalta la importancia de la utilización de la autobiografía para mostrar toda la complejidad que conlleva el proceso de crear un equipo.Una aplicación práctica de este estudio es la utilización de la autobiografía como recurso para reflexionar sobre la construcción de un equipo.

A lo largo del siglo XX la mujer ha reivindicado su papel en el mundo del deporte, si bien el deporte femenino ya era una realidad en Europa desde comienzos del siglo XX en nuestro país seguía existiendo reticencia por parte de las mujeres ante la práctica deportiva, donde se seguían reproduciendo aspectos de la cultura tradicional en los que la mujer restringía su actividad a la vida privada. El Descenso del Sella, gracias a su creador Dionisio de la Huerta, logra reunir en el Descenso Internacional del Sella, en Asturias, a deportistas de otras nacionalidades incluso antes de existir una Federación Española de Piragüismo. La participación extranjera femenina será la protagonista a mediados del siglo XX para poco a poco ir ganando peso la participación de palistas nacionales, los cambios de las condiciones socio-económicos de nuestro país permitirán a las mujeres implicarse en la práctica deportiva cosechando grandes triunfos.

El consumo de leche con cacao para favorecer la recuperación y el rendimientoen sesiones subsecuentes en deportes de resistencia ha cobrado interés en los últimosaños. El consumo de 1.2-1.5 g/kg/h de carbohidratos de alto índice glucémicolo antes posible una vez finalizado el ejercicio y hasta 4-6 horas parece adecuadopara restaurar los depósitos de glucógeno. Alternativamente, consumir 0.8 g/kg/hde carbohidratos en combinación con 0.4 g/kg/h de proteína también parece sereficaz. Además, la adición de proteína promueve la síntesis proteica y un mejor balanceneto proteico. La ingesta de leche con cacao también facilita la consecuciónde un adecuado estado de hidratación al reponer los fluidos perdidos, además de sualta concentración de electrolitos. Por tanto, y a pesar de que la literatura científicaaún es escasa, todo parece indicar que su consumo es igual o más efectivo que otrasbebidas deportivas comerciales para favorecer la recuperación.

The egg parasitoids, Trichogramma japonicum and Telenomus dignus, seem to have doubtful impact on the regulation of rice yellow stem borer, Scirpophaga incertulas – It is time for a reality check
Authors:   Consultant on Biocontrol, Agri-biotechnology and IPM, Bengaluru – 560 092, T. M Manjunath
Published: December 2023

The egg parasitoids, Trichogramma japonicum and Telenomus dignus, generally record a high rate of parasitism of egg masses, often 100%, but critical studies in India revealed that these, either alone or in combination, parasitized only up to 60% of the eggs in an egg mass, allowing the remaining 40% to hatch and cause potential damage. It is so because they could parasitize only those eggs that are laid on the upper surface and cannot reach out and parasitize eggs laid at the bottom layer. As a result of this inherent limitation resulting in partial parasitism of egg masses, these parasitoids, either by way of natural parasitism or artificial releases even in high numbers, seem to have a doubtful impact on the regulation of rice yellow stem borer (YSB), Scirpophaga incertulas. Tetrastichus schoenobii is also a common parasitoid of YSB, but it appears very late in the field and remains active only for a short period which greatly reduces its importance unless manipulated as suggested. It is time for a reality check and to be pragmatic in our approach in utilizing these parasitoids.
Male parental care in insects
Authors:   Department of Entomology, University of Agricultural Sciences, Bangalore 560065, India, B. N. Balaji , Kumaraswamy Sunil
Published: December 2023

Parental care is traditionally defined as costly behaviour by parents that increase the fitness of offspring. It may be uniparental, biparental or alloparental. In uniparental care, paternity assurance is usually repeated for copulation just before oviposition. Biparental care is favoured when sexual selection is not intense and when the adult sex ratio of males to females is not strongly skewed. Alloparental care is a seemingly altruistic and reproductively costly behaviour observed in over 120 mammalians and 150 avian species. Male parental care evolved exclusively from no care. Supporting models like the “enhanced fecundity model” and “overlapping brood model” hypothesize that male care is favoured because females do avoid care of their offspring. Biparental care largely arose by males joining caring females and was more labile in Holometabola than in Hemimetabola. Paternal care can be maintained under sexual selection which helps caring males to attract more mates.
Investigation on the Effect of Coating Temperature on the Properties of NbC Layer Coated with Pack Cementation Technique on GGG70 Nodular Graphite Cast Iron Surface
Authors: DAL Serkan
Published: December 2023

Nodular Graphite Cast Irons stand out with their high castability, high strength, vibration damping and high loading capacity. With today's technologies, the surface properties of materials can be improved by coating them with various methods and high-performance engineering materials can be obtained. Pack Cementation Technique is preferred among coating methods due to its relatively lower cost and applicability. In this study, it was aimed to coat NbC on the surface of GGG70 Nodular Graphite Cast Iron using the Pack Cementation Technique at 900 °C, 1000 °C and 1100 °C for 6 hours. The effect of temperature on the properties of the resulting coating layers was investigated. For this purpose, the surface morphologies of the samples were examined and their fracture toughness and hardness values were obtained. Coating morphologies were examined by XRD, optical microscope and SEM analysis and changes in coating structure and thickness were obtained. When the results were examined, it was determined that the coating thickness increased with the increase in coating temperature. Accordingly, it was observed that the fracture toughness value of the coatings first increased and then decreased slightly. Microhardness values increased approximately 5 times in the coating areas.

Published: December 2023

Low-cost instruments are used to achieve high sensitivity, accuracy and precision with electrochemical techniques, making them the most suitable analytical methods used to investigate the electrochemical properties of a new molecule. Among these techniques, cyclic voltammetry, which is widely employed, allows for the determination of electronic characteristics such as molecular energy levels and orbital structure, redox properties, sensor capabilities, surface activity, and more. The carbazole molecule can undergo derivatization from various positions, allowing for alterations in its electrical and optical properties. These compounds serve as heterocyclic building blocks that can be utilized as materials for organic sensitizers and semiconductors in optoelectronic devices. Due to the presence of a hydrogen atom in the nitrogen-hydrogen (N-H) bond within the carbazole structure, which can be replaced with different functional groups, carbazole is highly suitable for nitrogen-based derivatization studies. In this study, two different carbazole monomers (IIa and IIIa), which could be potential optoelectronic, were synthesized using the Ullman and Suzuki-Miyaura reaction and characterized using 1H NMR, 13C NMR, UV-Vis, and Flouresence spectroscopy techniques. The cyclic voltammetry experiments were performed using three different working electrodes (Au, Gc, Pt disk electrodes) for each compound. Since the optimum oxidation of the compounds was obtained from the voltammograms on the gold disk electrode, this electrode was used in the calculation of energy levels. HOMO and Eg values of the compounds were deduced from cyclic voltammetry experiments and the optical absorption bands, respectively.

Published: December 2023

Hydrazones especially nicotinic acid benzylidenehydrazide derivatives constitute an important class of compounds that has received much interest in recent years, due to their diverse biological characteristics, such as antimicrobial, anticonvulsant, analgesic, anti-inflammatory, antiplatelet, antituberculous and antitumor activities. These compounds have donor sites such as N and O which have non-bonding doublets which allow them to coordinate with metal ions. For this purpose, ten hydrazones structures were optimized in the DFT method, using the B3LYP functional, with the basis 6-31G** for all atoms, in the gas phase using the Gaussian 09 program. The structural, energetic (energies, EHOMO-LUMO gaps), electronic (dipolar moments, atomic charges) parameters were determined. A study of the stability of the ligands was carried out based on the relative energies to study the chemical reactivity of the optimized structures, we calculated the global reactivity parameters (ionization potential, electronic affinity, electronic chemical potential, absolute hardness, overall softness and overall electrophilicity). The results obtained show that All the systems considered are stabilized by two types of electronic effect. Either; an inductive attractor effect, with a coexistence of mesomeric effects. Analysis of chemical hardness values indicates that the most stable isomers found are the hardest, with larger HOMO/LUMO gaps, and therefore less reactive. As a result, charge transfer will be predominant. The most nucleophilic systems are also determined based on the calculation of the eletrophicity and nucleophilicity indices.

Nutrient profiling models are useful for describing the health value of foods and underpinning various nutrition-related public health strategies. They are generally based on a food’s content of several nutrients (e.g., protein, salt, carbohydrates). The aim of this study is to review information on the nutritional profiles of foods and beverages sold in Turkey. Ten food and drink categories were reviewed in six physical food stores and four online stores. A total of 1,000 foods and beverages, 100 products from each group, were checked for nutrient profile according to their labels. While all dairy products are produced locally, 74% of baby and young children foods are produced foreign. Snacks have the highest energy and saturated fat (on average 2072.6 kJ/579.4 kcal; 13.2±6.23 g respectively). Dried food and ingredients have the highest fat (on average 35.2 g±21.61). Confectionaries received the highest carbohydrates and sugars (on average 79.6±19.56 g; 56.0±27.41 g respectively). Chilled foods have the highest protein levels (on average 18.0±9.31 g). Condiments and sauces have the highest salt (3.4±4.59 g). Beverages have the lowest energy, fat, saturated fat, protein and salt (on average 160.3 kJ/37,7 kcal; 0.0±0.00 g; 0.0±0.00 g; 0.1±0.16 g; 0.0±0.15 g respectively). Dairy has the lowest carbohydrates (on average 5.8±4.52 g) and chilled foods have the lowest sugar (on average 2.0±0,69 g). As nutrient profiling models are increasingly used worldwide to support public health strategies, having an up-to-date resource listing them and detailing their characteristics is crucial. It is believed that the results of this study may provide an up-to-date guide for determining the nutrient profile of commercially packaged foods sold in Türkiye.

Published: December 2023

Drive shafts are the transmission components which transfer power from power source to required location. The connection may be between steering wheel and rack & pinion mechanism or gearbox to differential. As in gearbox to differential connection, operational conditions are harsh and high loads are generated, steel materials are mainly preferred to be used. Though steels have such advantages in cost, performance and durability, it is heavier compared to other engineering materials. Since international regulations dictate to decrease the carbon emissions rates due to global concerns, weight decrement of automobile components plays an important role in solving such problem. Considering the operational requirements and boundary conditions, weight reduction in steel parts might be tough. For this reason, alternative materials must be deeply investigated and implemented into the traditional technologies. In the scope of this study, fatigue and torsional strength of propeller shaft with composite tube and aluminum subcomponents were investigated.

Published: December 2023

Friction stir welding (FSW) connects the parts without melting the metal and produces a plasticized zone of metal. The main objective of this paper is to examine the temperature distribution that results from friction stir-lap welding of Al2024 alloy at varying rotating speeds and feed rates. Temperature distribution, heat flow, directional heat flux, thermal stresses, and strain energy are analyzed at different speeds of 700, 1000rpm, and at feed rate of 20 mm/min and 40 mm/min. Comparing the experimental temperatures with the simulated temperatures an error of 0.6% has been observed which is negligible. By comparing the numerical values of heat flux to the simulated values, the maximum error found to be 5.8% for the similar lap Al 2024-T3 joint. Temperature and heat flux values are gradually decreased from nugget zone to thermo-mechanical zone. But when compared to the nugget zone with the thermo-mechanical zone, the values of thermal stress and strain energy were abnormally altered.

The insurance market is an integral part of the country's financial system and is therefore extremely important for economic development. Any shocks in the insurance market may cause a slowdown in economic growth and development and have a negative impact on the country's financial system. The stability of the insurance market is ensured by the companies operating in it. That is why our analysis focuses on assessing the risk of insurance companies' bankruptcy and analyzing the main factors that affect the situation in the insurance market.This article analyzes the main approaches to assessing the risk of insurance companies depending on the size of the risk premium. A simple dynamic risk assessment model was applied.Our analysis of the literature has shown that general approaches to assessing the risk of insurance company failure depend on the overall situation in the country and the market itself. In countries with more frequent force majeure events, more complex and sophisticated models have been introduced to assess the required amount of risk premium to avoid bankruptcy.The market situation in Ukraine had been stable for a long time, but with the onset of the pandemic, certain problems began to arise. An analysis of one of the leading insurance companies in the market showed that before the war started, it had a bankruptcy risk close to zero. Unfortunately, it should be noted that military actions, which are force majeure circumstances, complicate the quantitative analysis, as Ukrainian companies do not have effective mechanisms to cover this type of risk.It is established that a company cannot arbitrarily determine the amount of risk premium based on its own needs. This value will also be influenced by external macroeconomic factors that will affect not only the overall economic situation but also all participants in the insurance market, including consumers of insurance services.

Background. Higher education in this digital era is faced with significant changes, especially with the development of artificial intelligence (AI) technology.
Purpose. This research aims to explore the potential and limitations of integrating AI technology in improving the quality of distance learning and present findings that can guide the development of AI-based pedagogy.
Method. This research method adopts a quantitative survey approach to detail the integration of artificial intelligence (AI) technology in the context of distance learning in higher education. A total of 20 students were randomly selected as respondents, with sample selection using the purposive sampling method. This process ensures maximum representation of students who have significant experience with the integration of AI technology in their learning. Data was collected through questionnaires focused on effectiveness, adaptability of material, and level of interactivity during learning. Next, descriptive and inferential statistical analysis will analyze patterns and relationships between variables to explore the effectiveness of AI technology, the factors that influence it, and its impact on student learning experiences.
Results. Survey results show that the majority of students actively use AI technology, especially several times a week, and express a high level of satisfaction with the use of AI technology in distance learning. Virtual Reality or Augmented Reality learning experiences were considered to benefit the most, even though all respondents experienced challenges or obstacles in using AI technology.
Conclusion. The conclusions of this research emphasize the need to address these challenges to maximize the benefits of integrating AI technology in increasing the effectiveness and efficiency of distance learning in higher education.

Published: December 2023

We study the electromagnetic contribution to elastic neutrino-nucleon scattering processes. The neutrino
electromagnetic charge, magnetic, electric, and anapole form factors of both diagonal and transition types in
the mass basis are taken into account in the present formalism. When treating the nucleon electromagnetic
vertex, we take into account not only the charge and magnetic form factors of a nucleon, but also its electric and
anapole form factors. We examine the effects of the neutrino magnetic moment on elastic neutrino-nucleon
scattering and how they can be disentangled from those of the strange form factors contributions to the
nucleon’s weak neutral current.

Published: December 2023

The results of modeling the dependence of the «red leak» of photometric filters on various factors (color index
𝑉 −𝑅, luminosity class, interstellar reddening, air mass and PWV) during observations of stars are presented.
The error arising from not taking into account the «red leak» in the case of filters used on the 0.6-m telescope
of the CMO SAI can amount to 0.6
𝑚 − 0.8
𝑚 for late stars. Algorithms for reducing observational data are
presented for filters 𝑈 and 𝐵. The results of observations of the rapid variability of two symbiotic stars CH Cyg
and SU Lyn with cold components of very late spectral types are presented. For CH Cyg, rapid variability
was detected on both observation dates. Taking into account the «red leak» effect, the amplitude in the 𝐵
band was 0.10𝑚 on November 6, 2019 and 0.19𝑚 on December 15, 2022, with a characteristic variability time
of about 20 minutes. For SU Lyn, no rapid brightness variability was detected in the 𝐵 band on February 2,
2023 (with an accuracy of 0.003𝑚)

The paper considers the foci of the most severe earthquakes in the Russian segment of the Arctic that occurred
during the entire observation period, from 1976 to the present. The stress and strain fields were studied by
analyzing the tensor of the seismic moment of registered earthquakes. This analysis is being conducted for
the first time. Spatial distributions of the Lode-Nadai coefficient and the rate of seismotectonic deformation
are obtained.

Desa Labuko merupakan salah satu desa yang kaya akan hasil pertanian khususnya kelapa, namun hanya diolah sebagai kopra yaitu daging buah kelapa yang dikeringkan sehingga air kelapa yang menjadi hasil sampingnya dibuang begitu saja. Kegiatan ini bertujuan untuk memberi pengetahuan tentang pemanfaatan air kelapa sebagai bioplastik sehingga mengurangi sampah plastik. Bioplastik tersebut dimodifikasi dari nata de coco sehingga cepat larut dalam air. Metode yang digunakan adalah penyuluhan dan diseminasi informasi, demonstrasi dan tanya jawab. Hasil kegiatan pengabdian ini telah meningkatkan pengetahuan tentang pemanfaatan air kelapa, cara pembuatan nata de coco dan bioplastik. Program ini juga diikuti oleh masyarakat dengan sangat antusias, aktif dalam diskusi serta mengikuti hingga selesainya kegiatan. Kesuksesan terlihat dari evaluasi positif yang mencapai 97%. Selain itu, kemitraan yang kuat antara penyelenggara, pemerintah setempat, khususnya kepala desa sebagai stakeholder utama, menunjukkan komitmen terhadap keberlanjutan kegiatan ini.
MENTAL HEALTH, PROTECTIVE MEASURES, COVID-19: A STUDY ABOUT HEALTHCARE WORKERS IN BRAZIL

Published: December 2023

During the COVID-19 pandemic, health workers’ occupational stress increased due to the amount of medicine needed by patients. Aims: This research aims to evaluate the fear generated by the risk of contracting COVID-19 among health professionals working in the intensive care unit of a Brazilian philanthropic hospital. Methods: This cross-sectional study adopted a quantitative approach. We collected data through questionnaires completed by a multi-professional team from an adult intensive care unit. The survey included questions on the professionals’ sociodemographic data and items from the adapted Information Related to the Health Unit and Patient Care questionnaire, the Fear of COVID-19 Scale, and the Patient Health Questionnaire-9. In addition, participants were asked about use of personal protective equipment (PPE) post-vaccination. Results: In total, 108 employees responded. There was an association between the PHQ-9 and the FCV-19S in terms of those respondents do not felt prepared to face COVID-19 and had feelings of insecurity for themselves and their family members due to the pandemic. Besides that, there was an apparent discrepancy between the respondents’ answers and the hospital’s protocol about the reused PPE. Conclusion: This lack of alignment, about protocol and reused PPE, generates more health costs because public resources finance the hospital through the Unified Health System. The use of PPE must continue after vaccination. Restriction policies, such as presenting a vaccination card when entering closed places (which in practice is not happening in most cities in Brazil) and approaching individuals when not using PPE are essential for infection control.
Déjà Vu: The Untenable Reality of the Pavement Dwellers of Dhaka – Evidence from Three Decades
Authors: Begum Anwara , Hossain Kazi Zubair
Published: December 2023

Pavement dwellers migrate to the city in search of better opportunities. Their commitment to this way of life is based on an expectation of benefits in the destination area. This study examined five aspects of pavement dwellers’ reality: demographics, socioeconomics, migration outcomes, living conditions, and fulfillment of expectations. A mixed-method data collection exercise resulted in 64 pavement dwellers’ accounts of their current situation in Dhaka city, which were compared to similar studies from 1991 and 1993. The results show that their conditions have remained unchanged. Though half of the migration occurred for economic reasons, the real income level has remained the same as in 1991. Shelter and employment remain elusive, and moving to slums is financially infeasible. More than half of those interviewed lived on the pavement for access to a livelihood. Most declared that they could not access social safety nets. The persistence of pavement dwelling in the face of remarkable economic growth demands the refocusing of policies on urban poverty eradication.
