Sustainable and Renewable Energy initiatives across the globe: Opportunities and challenges
Authors: Ha Trang Nguyen , Rao MVKS
Published: March 2024

In 2023, China, USA, India, Russia, and Japan are the top 5 countries in the world with the highest electricity consumption per year respectively. Similarly, Most of the countries across the globe are utilising massive electricity, coal, petroleum, and other natural resources. Hence, it is inevitable to produce sustainable and renewable energy for domestic and industrial purposes. Right now, the majority of the countries have taken initiatives to generate sustainable and renewable energy across the globe. China is at the top list in sustainable and renewable energy initiatives and production, followed by the USA, India, Russia, and Japan.

Hence, an attempt is made to study sustainable and renewable energy initiatives across the globe and also observe the opportunities and challenges on the same across the globe would be very helpful to proceed further in this area of knowledge with the main objectives of understanding the concept of sustainable and renewable energy; reviewing the existing literature on the topic concerned; reviewing opportunities and challenges of the same across the globe. The study is an observatory in nature and revealed that the main opportunity is to get support from respective governments of the countries to exploit the sustainable and renewable energy sources that are abundant and helpful for economic development. Similarly, mitigating environmental impact, ensuring electricity security, applying technological advances and creating jobs are other opportunities to discover. Besides these opportunities, sustainable and renewable energy initiatives also face some challenges, via lack of facilities and infrastructures to bring these initiatives into our lives; additionally, cost, time, manpower and awareness are also becoming challenges for these initiatives. In some perspectives, sustainable and renewable energy is still a new field that needs a lot of time to be fully understood and make it a part of our lives.
Cobweb phenomenon in rubber market of Kerala
Authors: Karunakaran N. , Vishnuprathap M. , Shilpa V. K.
Published: March 2024

More than 90 percent of rubber produced in India is from Kerala. The state holds a dominant position both in area and production. But now a day farmers are looking at alternative crops or not tapping their rubber as prices have crashed due to lack of demand, imports and labour cost. The study revealed that during high priced season farmers in Kerala shifted from other plantation crops like cashew, coconut, etc. to rubber or they focus only in rubber production but in higher prices, seeks to benefit from higher prices. These results in surplus production, more than the demand, resulting in a price crash, often referred to as the ‘problem of plenty’. Seeing the low prices, farmers switch to different crops or produce less of the same crop, leading to lower than usual production for that particular crop. This increases the prices of crops, completing the cyclical variations in price and production reflects Cobweb phenomenon.
Ethical issues in un-organized market for fruits and vegetables in Mysore district
Authors: Fathima Gowhar
Published: March 2024

Markets for fresh Fruits and vegetables in India are mainly characterized as unorganized markets. Most farmers either willingly or forcefully sell away fresh fruits and vegetables at the farmyard or in the unorganized market. Lack of marketing knowledge, inability in time management, timidness in moving forward into the advanced world, working capital crunches, domestic compulsions, absence of proper logistic arrangements, poor storage facilities, and social stigma influence the farmers in disposing of fruits and vegetables grown by them in the unorganized markets. Heavy price fluctuations either act as a boon sometimes or bane other times. Further, the deceptive practices of intermediaries add to the woes of farmers. Charging high commissions, improper weighing, and irregular payments are important deceptive practices of middlemen. The farmers get elated when prices shoot up and dishearten when prices crash. The incidences of throwing vegetables on the street when the prices get down to the nadir and getting back to the villages cursing by the farmers are often reported. Lacking market intelligentsia is affecting gullible farmers very much. Ninety-nine percent of the businesses are in the unorganized sector, and reports suggest they are declining. The divergence between the two sectors is visible. The head of the largest luggage manufacturer recently said their growth is surging because the smaller units are not doing well. The rules of economic gains enable the organized sector to corner most of the development gains. The marginalized sections are expected to be satisfied with their meager material gains. Secondary data is used to collect the data, and the study is focused only on Ethical issues in Unorganized markets for fruits and vegetables in Mysore District.

Published: March 2024

Avena sativa (oat) has emerged as a potential therapeutic candidate for asthma, a global health challenge characterized by chronic airway inflammation. This research investigates the anti-asthmatic potential of the Hydro-Alcoholic Extract of Avena sativa (HAEAS) in a guinea pig asthma model induced by histamine and ovalbumin. The study explores the influence of HAEAS on oxidative stress markers, leucocytes, eosinophils, and histopathological changes in lung tissues. Results reveal that HAEAS, particularly at 400 mg/kg, significantly increases the latent period and percentage protection in histamine induced bronchospasm. In ovalbumin-sensitized guinea pigs, HAEAS demonstrates a notable reduction in total leucocyte count, eosinophils, neutrophils, and macrophages in bronchoalveolar lavage fluid. Moreover, HAEAS exhibits antioxidative effects by increasing superoxide dismutase levels and decreasing malondialdehyde levels. Histopathological analysis demonstrates a decrease in inflammatory cell infiltration, hyperplasia, and bronchoconstriction. This study highlights the potential of Avena sativa as a novel therapeutic avenue for asthma, offering anti-inflammatory and antioxidant benefits.

Проблемы расследования преступлений, связанных с трудовыми правоотношениями
Authors: Василенко Н.А.
Published: March 2024

В настоящей научной работе автором исследуется проблема расследования преступления, связанных с посягательством на трудовые права граждан. Рассмотрены основные составы преступлений. Автором сделан акцент на том, что обстоятельства, подлежащие доказыванию в ходе расследования данных преступлений, расширены засчет особенностей объекта посягательства. Так, например, следователю необходимо установить факт наличия трудовых правоотношений между работником и работодателем, вследствие заключенного между ними трудового договора или иного соглашения. Исследован ряд проблем, возникающих в ходе расследования данных преступлений. В частности, отмечено противодействие со стороны работодателя, недостаток специальных знаний следователя в области трудового права. Сделан вывод о том, что ход расследования напрямую зависит от сложившейся ситуации на первоначальном этапе расследования, связанной с показаниями потерпевшего. От их точности, объема, количества предоставленных документов и будет зависеть быстрота и эффективность расследования.

TEMPORAL ORGANIZATION OF ORAL ENGLISH AND GERMAN RELIGIOUS SERMONS (THEOLINGUISTIC APPROACH)
Authors: Kravchenko N. O. , Bohuslavskyi S. S.
Published: March 2024

The article is dedicated to exploring the temporal organization of texts in Anglican and Lutheran sermons, which are an integral part of worship in their respective churches. The study of homiletic and theolinguistic literature, along with an examination of the compositional features of the analysed sermons, has allowed for the identification of four compositional parts present in both types of sermons (theme manifestation, citation, interpretation, conclusion). Each part is characterized by relative semantic and structural autonomy, serving specific pragmatic purposes.
The research material, consisting of oral English and German sermons, underwent perceptual, auditory, and instrumental analysis. A comprehensive auditory and instrumental analysis of the temporal characteristics of the preachers’ speech allows the conclusion that there is unity not only in the pragmatic directives of preachers in the two most widespread Protestant traditions but also in the prosodic structure of oral sermons. Among the integral temporal parameters at the perceptual level, pauses and contrasting tempo play a leading role in creating the influential effect of sermons.
Regarding integral objective temporal parameters, common patterns in the temporal organization of the introductory and main parts of the text are identified. Differentiating features include significant differences between Anglican and Lutheran sermons in the concluding part. Lutheran sermons demonstrate relatively stable use of a normal tempo with a tendency toward slowing down, while Anglican sermons exhibit contrasting use of both slowed and accelerated tempo, creating a “broken” rhythm of articulation that enhances the influential effect of this part of the sermon.
Based on the identified integral temporal means involved in the construction of the analysed texts, it can be stated that Anglican and Lutheran sermons belong to the same type of homiletic discourse.

Nuestra perspectiva se nutre del cuestionamiento feminista de la Bildungsroman, del simbolismo mitocrítico y de los recursos formales del relato gótico, para mostrar cómo, en su conjugación, se genera un texto tan original como conmovedor.
Hacia una enseñanza de lengua con enfoque comunicativo y crítico: cuatro claves para la educación básica
Authors: Martínez Ortega Francisco Javier
Published: March 2024

El currículo ecuatoriano de educación básica, desde 2016, contiene el desarrollo de la criticidad y de la competencia comunicativa en sus objetivos generales de formación (el perfil de salida del bachillerato ecuatoriano). Específicamente, adoptó el enfoque comunicativo para la enseñanza de lengua; sin embargo, en el contexto de la Formación Inicial Docente y de investigaciones en aulas de educación básica, hemos encontrado que no se lleva cabalmente a la práctica. El presente ensayo presenta una síntesis y reflexión sobre algunos hallazgos relacionados con la enseñanza comunicativa y crítica de la lengua en aulas de Educación General Básica. En diálogo con referentes teóricos especializados como la teoría psicogenética, el interaccionismo sociodiscursivo y la literacidad crítica, el trabajo expone cuatro claves para fortalecer la enseñanza de lengua siguiendo el enfoque comunicativo e integrando el objetivo del desarrollo de la criticidad de los estudiantes.
The Controversial Maternity Supplement Due to Demographic Contribution: Practical Issues and Regulatory and Judicial Responses
Authors: Smintinica Catalina
Published: March 2024

This paper addresses the study and analysis of the establishment of the maternity supplement towards the current contributory pension supplement for the reduction of the gender gap from three key points. In the first place, and to understand the establishment of the pension supplement, the basis and legal regime of the so-called maternity supplement is analysed. Secondly, the arguments of the CJEU of 12 December 2019, case C-450/18 are set out, which, as a result of the practical application of the maternity supplement for demographic contribution, declared that there was direct discriminatory treatment on grounds of sex between men and women and that the Spanish legislation was contrary to Council Directive 79/7/EEC,  of 19 December 1978 on the progressive implementation of the principle of equal treatment for men and women in matters of social security. Likewise, due to its relevant interest in the matter, the latest CJEU in the matter is addressed, specifically the CJEU of 14 September 2023, case C-311/22. Finally, the legal regime of the new pension supplement for the reduction of the gender gap is briefly described.
The regulatory effects of (p)ppGpp and indole on cAMP synthesis in Escherichia coli cells
Authors: Kashevarova N. M. , Khaova E. A. , Tkachenko A. G.
Published: March 2024

Bacterial stress adaptive response is formed due to changes in the cell gene expression profile in response to alterations in environmental conditions through the functioning of regulatory networks. The mutual influence of network signaling molecules represented by cells’ natural metabolites, including indole and second messengers (p)ppGpp and cAMP, is hitherto not well understood, being the aim of this study. E. coli parent strain BW25141 ((p)ppGpp+) and deletion knockout BW25141ΔrelAΔspoT which is unable to synthesize (p)ppGpp ((p)ppGpp0) were cultivated in M9 medium supplemented with different glucose concentrations (5.6 and 22.2 mM) in the presence of tryptophan as a substrate for indole synthesis and in its absence. The glucose content was determined with the glucose oxidase method; the indole content, by means of HPLC; and the cAMP concentration, by ELISA. The onset of an increase in initially low intracellular cAMP content coincided with the depletion of glucose in the medium. Maximum cAMP accumulation in the cells was proportional to the concentration of initially added glucose. At the same time, the (p)ppGpp0 mutant showed a decrease in maximum cAMP levels compared to the (p)ppGpp+ parent, which was the most pronounced in the medium with 22.2 mM glucose. So, (p)ppGpp was able to positively regulate cAMP formation. The promoter of the tryptophanase operon responsible for indole biosynthesis is known to be under the positive control of catabolic repression. Therefore, in the cells of the (p)ppGpp+ strain grown in the tryptophan-free medium that were characterized by a low rate of spontaneous indole formation, its synthesis significantly increased in response to the rising cAMP level just after glucose depletion. However, this was not observed in the (p)ppGpp0 mutant cells with reduced cAMP accumulation. When tryptophan was added to the medium, both of these strains demonstrated high indole production, which was accompanied by a decrease in cAMP accumulation compared to the tryptophan-free control. Thus, under glucose depletion, (p)ppGpp can positively regulate the accumulation of both cAMP and indole, while the latter, in its turn, has a negative effect on cAMP formation.
Manifestation of agronomically valuable traits in the progeny of a sorghum mutant carrying the genetic construct for RNA silencing of the γ-kafirin gene

Published: March 2024

Improving the nutritional value of grain sorghum, a drought- and heat-tolerant grain crop, is an important task in the context of global warming. One of the reasons for the low nutritional value of sorghum grain is the resistance of its storage proteins (kafirins) to proteolytic digestion, which is due, among other things, to the structural organization of protein bodies, in which γ-kafirin, the most resistant to proteases, is located on the periphery, encapsulating more easily digested α-kafirins. The introduction of genetic constructs capable of inducing RNA silencing of the γ-kafirin (gKAF1) gene opens up prospects for solving this problem. Using Agrobacterium-mediated genetic transformation of immature embryos of the grain sorghum cv. Avans we have obtained a mutant with improved digestibility of endosperm proteins (up to 92 %) carrying a genetic construct for RNA silencing of the gKAF1 gene. The goal of this work was to study the stability of inheritance of the introduced genetic construct in T2–T4 generations, to identify the number of its copies, as well as to trace the manifestation of agronomically valuable traits in the offspring of the mutant. The mutant lines were grown in experimental plots in three randomized blocks. The studied lines were characterized by improved digestibility of kafirins, a modified type of endosperm, completely or partially devoid of the vitreous layer, an increased percentage of lysine (by 75 %), reduced plant height, peduncle length, 1000-grains weight, and grain yield from the panicle. In T2, a line with monogenic control of GA resistance was selected. qPCR analysis showed that in different T3 and T4 plants, the genetic construct was present in 2–4 copies. In T3, a line with a high digestibility of endosperm proteins (81 %) and a minimal decrease in agronomically valuable traits (by 5–7 %) was selected.
Genetic history of the Koryaks and Evens of the Magadan region based on Y chromosome polymorphism data
Authors: Malyarchuk B. A. , Derenko M. V.
Published: March 2024

In order to clarify the history of gene pool formation of the indigenous populations of the Northern Priokhotye (the northern coast of the Sea of Okhotsk), Y-chromosome polymorphisms were studied in the Koryaks and Evens living in the Magadan region. The results of the study showed that the male gene pool of the Koryaks is represented by haplogroups C-B90-B91, N-B202, and Q-B143, which are also widespread in other peoples of Northeastern Siberia, mainly of Paleo-Asiatic origin. High frequency of haplogroup C-B80, typical of other Tungus-Manchurian peoples, is characteristic of the Evens of the Magadan region. The shared components of the gene pools of the Koryaks and Evens are haplogroups R-M17 and I-P37.2 inherited as a result of admixture with Eastern Europeans (mainly Russians). The high frequency of such Y chromosome haplogroups in the Koryaks (16.7 %) and Evens (37.8 %) is indicative of close interethnic contacts during the last centuries, and most probably especially during the Soviet period. The genetic contribution of the European males’ Y chromosome significantly prevails over that of maternally inherited mitochondrial DNA. The study of the Y chromosome haplogroup diversity has shown that only relatively young phylogenetic branches have been preserved in the Koryak gene pool. The age of the oldest component of the Koryak gene pool (haplogroup C-B90-B91) is estimated to be about 3.8 thousand years, the age of the younger haplogroups Q-B143 and N-B202 is about 2.8 and 2.4 thousand years, respectively. Haplogroups C-B90-B91 and N-B202 are Siberian in origin, and haplogroup Q-B143 was apparently inherited by the ancestors of the Koryaks and other Paleo-Asiatic peoples from the Paleo-Eskimos as a result of their migrations to Northeast Asia from the Americas. The analysis of microsatellite loci for haplogroup Q-B143 in the Eskimos of Greenland, Canada and Alaska as well as in the indigenous peoples of Northeastern Siberia showed a decrease in genetic diversity from east to west, pointing to the direction of distribution of the Paleo-Eskimo genetic component in the circumpolar region of America and Asia. At the same time, the Evens appeared in the Northern Priokhotye much later (in the XVII century) as a result of the expansion of the Tungusic tribes, which is confirmed by the results of the analysis of haplogroup C-B80 polymorphisms.
A universal panel of STR loci for the study of polymorphism of the species Canis lupus and forensic identification of dog and wolf
Authors: Hrebianchuk A. E. , Tsybovsky I. S.
Published: March 2024

Commercial panels of microsatellite (STR) loci are intended for DNA analysis of the domestic dog (Canis lupus familiaris) and, therefore, when genotyping the Grey wolf (Canis lupus lupus), most markers reveal significant deviations from the Hardy–Weinberg equilibrium and have a low informative value, which complicates their use in a forensic examination. The aim of this study was to select STR markers that equally effectively reflect population polymorphism in the wolf and the dog, and to create a universal panel for the identification of individuals in forensic science. Based on the study of polymorphisms of 34 STR loci, a CPlex panel of 15 autosomal loci and two sex loci was developed, which is equally suitable for identifying wolfs and dogs. Analysis of molecular variance (AMOVA) between samples revealed significant differentiation values (FST = 0.0828, p < 0.05), which allows the panel to be used for differentiating between wolf and dog samples. For the first time in the forensic examination of objects of animal origin in the Republic of Belarus, population subdivision coefficients (θ­-values) were calculated for each of the 15 STR loci of the test system being reported. It was shown that the values of the genotype frequency, when averaged over all studied animals without and with considering the θ­-value, differ by three orders of magnitude (3.39 · 10–17 and 4.71 · 10–14, respectively). The use of population subdivision coefficients will provide the researcher with the most relevant results of an expert identification study. The test system was validated in accordance with the protocol of the Scientific Working Group on DNA Analysis Methods. A computational tool was developed to automate the analysis of genetic data on the wolf and dog in the forensic examination; two guides were approved for practicing forensic experts. This methodology is being successfully used in expert practice in investigating cases of illegal hunting, animal abuse and other offenses in the Republic of Belarus.

Throughout history, humans have been attempting to develop the ornamental features of domestic animals in addition to their productive qualities. Many chicken breeds have developed tufts of elongated feathers that jut out from the sides and bottom of the beak, leading to the phenotype known as muffs and beard. It is an incomplete autosomal dominant phenotype determined by the Mb locus localised on chromosome GGA27. This project aimed to analyse the genetic diversity of chicken breeds using full genomic genotyping with the Chicken 60K BeadChip. A total of 53,313 Single Nucleotide Polymorphisms were analysed. DNA was obtained from breeds with the muffs and beard as a marker phenotype: Faverolles (n = 20), Ukrainian Muffed (n = 18), Orloff (n = 20), Novopavlov White (n = 20), and Novopavlov Coloured (n = 15). The Russian White (n = 20) was selected as an alternative breed without the muffs and beard phenotype. The chickens are owned by the Centre of Collective Use “Genetic Collection of Rare and Endangered Breeds of Chickens” (St. Petersburg region, Pushkin), and are also included in the Core Shared Research Facility (CSRF) and/or Large­Scale Research Facility (LSRF). Multidimensional scaling revealed that the Novopavlov White and the Novopavlov Coloured populations formed a separate group. The Ukrainian Muffed and the Orloff have also been combined into a separate group. Based on cluster analysis, with the cross­validation error and the most probable number of clusters K = 4 taken into account, the Orloff was singled out as a separate group. The Ukrainian Muffed exhibited a notable similarity with the Orloff under the same conditions. At K = 5, the populations of the Novopavlov White and the Novopavlov Coloured diverged. Only at K = 6, a distinct and separate cluster was formed by the Ukrainian Muffed. The Russian White had the greatest number of short (1–2 Mb) homozygous regions. If the HOXB8 gene is located between 3.402 and 3.404 Mb on chromosome GGA27, homozygous regions are rarely found in the chickens with the muffs and beard phenotype. Scanning the chicken genome with the Chicken 60K BeadChip provided enough information about the genetic diversity of the chicken breeds for the peculiarities of the development of the ornamental muffs and beard phenotypes in them to be understood. For example, Phoenix bantams, whose tail feathers grow throughout their lives, require greater consideration of husbandry conditions.

Authors: Calzada Falcón Fernando
Published: March 2024

Un ejemplo de impuesto directo de carácter progresivo es el impuesto predial, mismo que en México lo aplica uno de los tres órdenes de gobierno, el más cercano a las necesidades de la población, es decir, el municipal. Este gravamen en Centro, Tabasco, al igual que en la mayoría de los municipios del país con población predominantemente urbana, representa la principal fuente de ingresos tributarios y de ingresos propios municipales. Se revisa la evolución reciente de su recaudación y de su comportamiento actual, de su participación en los ingresos propios y en la recaudación del total de los 17 municipios del estado, del comportamiento del número de cuentas prediales, cuyo pago está al corriente de la recaudación por predio y de qué tanto ha avanzado el pago por la vía de la plataforma digital.

El supuesto reside en evaluar sí el nivel de estudio se encuentra directamente vinculado con el discernimiento de frases discriminantes.
MATERIAL Y MÉTODO: Se fundamenta en el análisis cuantitativo de corte correlacional; por su parte, el instrumento de medición se estructura operacionalmente a partir de expresiones convencionales de acuerdo con los cinco tipos de discriminación previamente consignados. Para la interpretación de datos, se aplicó el coeficiente correlacional de Pearson, con un nivel se significancia de 0.05.  
RESULTADOS: Existe una relación directa y positiva entre el grado de estudio y el discernimiento de expresiones racistas y homofóbicas. En cambio, las expresiones clasistas y sexistas presentan una relación moderada. Finalmente, para el caso de expresiones etnocentristas prevalece una correlación dispersa; esto es, los grados de estudio no tienen una correlación positiva o negativa con respecto al discernimiento de frases.
CONCLUSIÓN: Se espera instruir sobre estas formas de discriminación en estudiantes de nivel superior, con el propósito de difundir un lenguaje inclusivo y libre de violencia.
