Yellow mosaic disease (YMD) of cowpea, predominantly caused by mungbean yellow mosaic India virus (MYMIV) and mungbean yellow mosaic virus (MYMV) is a major constraint to the production of cowpea (Vigna unguiculata L.) in India resulting in significant yield reductions. The present study extensively evaluated 1127 cowpea germplasm accessions from the National Gene Bank of India, New Delhi, at two hotspot locations (Hyderabad and Delhi) for their response to YMD. About 181 accessions showed no symptoms in field screening at both locations and were considered putatively resistant. A set of the best 100 out of 181 was selected for further confirmation of resistance to MYMIV through whitefly-mediated screening along with 40 accessions known to be susceptible to YMD. The results of whitefly-mediated transmission confirmed MYMIV resistance in 20 accessions with a disease score of zero. Further, the YMD-associated Begomovirus was characterized using rolling circle amplification coupled with sequencing of the full DNA-A genome of MYMIV, which shared an identity of 99.02% with the MYMIV isolate infecting cowpea in Pakistan. The 20 cowpea accessions identified as novel resistant sources to MYMIV in the present study could be used for mapping resistance genes and as donors in resistance breeding for yellow mosaic disease

Published: June 2024

Rising environmental temperature has become a major concern in global wheat production since it has critical effects on plant growth,development and yield. Elevated temperatures have become. Further understanding of the processes behind the development of heattolerance is necessary for significant agricultural crops. Cytosine methylation in DNA plays an essential function in epigenetic regulation of gene expression at various developmental stages and environmental stress in plants. In this study, we report the comparative analysis of cytosine methylation in the coding region of the Rubisco activase (Rca) gene in heat tolerant (RAJ3765) and heat susceptible (HUW510)genotypes of wheat in four growth stages under control and heat-stressed conditions in CG, CHG and CGG contexts. We found that the overall 5-mC increased due to heat stress in HUW510 during tillering (25%), boot stage (25%), heading (48%) and anthesis (50%) as compared to RAJ3765 during tillering (21%), boot stage (4%), heading (4%) and anthesis (11%). Additionally, gene expression profiling by using qPCR at the different plant growth stages also showed the decline in the gene expression in the leaf samples in both the genotypes due to heat stress, with a minimum in the susceptible genotype at the anthesis stage. The study will increase the knowledge on the molecular regulation of photosynthetic pathways by cytosine methylation which would assist in selection and manipulation of heat tolerance in wheat.

Authors: Tran Thien Khanh , Ha Pham Thi Thu , Henry Robert J. , Tuan Truong Minh
Published: June 2024

Indica rice variety, IR50404 is the most-grown rice in Vietnam’s Mekong Delta. It is susceptible to multiple blast diseases, making it an ideal genotype for identifying pathological trait mutations. Chemically induced mutant lines were derived from IR50404 by treating seeds with ethyl methanesulfonate (EMS) (0.1 and 0.125%), methyl salicylate (MeSA) (0.1 and 0.125 mM), and their combinations. Chlorophyll, proline, and protease enzyme inhibitors were examined for disease tolerance in mutant rice-based plants. Blast resistance (41.6%) and protease inhibition (30.4%) were highest in T5 (0.1% EMS + 0.1 mM MeSA). Proline (3.91 g/mL) and chlorophyll (8.52 g/mL) concentrations were significantly higher after 0.125% EMS treatment than in the untreated control.In addition, a high rate of protease inhibition (30.4%) was improved after treatment with 0.125% EMS + 0.125 mM MeSA. Results showed that blast resistance was improved by 0.1% EMS and MeSA.This also has implications for the breeding of plant varieties other than rice

The System of Professional Tasks as a Means of Developing Professional Competencies for Future Teachers of Mathematics in the Course of Mastering
the Discipline “Algebra and Number Theory”
Authors: Matveeva V. A. , Samsikova N. A.
Published: June 2024

The article deals with the problem of forming professional competencies in
future teachers of mathematics. The professional task is considered as a means of forming
professional competencies. The article presents a system of professional tasks developed
in the framework of the discipline “Algebra and Number Theory”. The presented typology
includes four types of tasks aimed at modeling the teacher’s activity within the discipline.
It should be noted that the developed system of tasks is aimed not only at designing the
teacher’s skills to work with the teaching material (work with definitions, theorems
and their proofs), but also at forming constructive (composing tasks according to a set
of given indicators), creative (solving non-standard tasks, proof tasks with subsequent
transformation) and communicative (pedagogical situations) skills.
Semantic Components of the Conceptual Field Labor as Structural
Elements of the Holiday Macrofield in Russian
Authors: Yufan Zhang
Published: June 2024

The article considers the linguistic units (words and phraseological units (PU)),
which are part of the conceptual field LABOR and act as structural elements of the macrofield HOLIDAY: their dictionary interpretations containing the seme “work”, “activity”,
etc. are described; the model of the conceptual field LABOR is established; its structure (core and periphery) is defined. The studied units are components of the linguistic picture
of the world and a reflection of the consciousness of a native speaker. The cognitive
consciousness of a native speaker of the Russian language determines the specificity of
the studied conceptual field reflected in the semantic space of the language unit. The
article reveals similarities and differences between the lexemes labor — work, activity. The
data of etymological dictionaries make it possible to establish genetic links between the
lexemes labor — work, activity, which form a synonymic series and have subtle semantic
differences: labor is “an activity based on creativity, voluntariness and value”; work is “an
activity based on coercion”

Authors:   Universitatea Alexandru Ioan Cuza Iaşi, Nistor Adina-Lucia
Published: June 2024

The present study aims to analyze important features of the heroes who fought the Germanic wars of antiquity, starting from Old German words that have been preserved until today in the names of individuals. Thus, in both German first names and surnames, we find the following appellatives from the semantic sphere of war and weapons (ēra ”honour”, gund, hadu, hiltja, wīg ”war”, sigu ”victory”, ask ”ash pike”, brant ”sword”, gēr ”spear”, helm ”helmet”), wild animals (wolf ”wolf”, bero ”bear”, arn ”eagle”, ebur ”boar”, falco ”falcon”), the sovereign (burg ”fortress”, fridu ”protection against weapons”, rīhhi ”ruler, power”, thiot ”people”), as well as adjectives that refer to the attributes of warriors (adal ”distinguished, noble, chosen”, beraht ”bright”, kuoni ”brave”, liob ”kind, dear”, māri ”famous”, trūt ”close, beloved”) (e.g. Erhard, Gunter, Hilger, Siegbert, Wighard; Aschwin, Gerhard, Helmut; Wolfgang, Bernhard, Eberhard; Adalbert, Konrad, Liebward, Dietmar, Trudbert and others). The work also presents the most frequent surnames of Germanic origin in Germany (2005) and Transylvania (1935). With the weakening of gentile and tribal organizations, and with the advent of Christianity, many names of Germanic origin in the German language were replaced by names of saints and names from the New Testament.

Authors: Chandler Julie M. , Ye Wenyu , Mi Xiaojuan , Doty Erin G. , Johnston Joseph A.
Published: June 2024

Background: Impact of Alzheimer’s disease (AD) progression on patient health-related quality of life (HRQoL), caregiver time, and societal costs is not well characterized in early AD. Objective: To assess the association of change in cognition with HRQoL, caregiver time, and societal costs over 36 months, and estimate the impact of slowing disease progression on these outcomes. Methods: This post-hoc analysis included patients with amyloid-positive mild cognitive impairment (MCI) and mild AD dementia (MILD AD) from the 36-month GERAS-US study. Disease progression was assessed using the Mini-Mental State Examination score. Change in outcomes associated with slowing AD progression was estimated using coefficients from generalized linear models. Results: At baseline, 300 patients had MCI and 317 had MILD AD. Observed natural progression over 36 months was associated with: 5.1 point decline in the Bath Assessment of Subjective Quality of Life in Dementia (BASQID) score (for HRQoL), increase in 1,050 hours of total caregiver time, and $8,504 total societal costs for MCI; 6.6 point decline in the BASQID score, increase in 1,929 hours of total caregiver time, and $12,795 total societal costs for MILD AD per person. Slowing AD progression by 30% could result in per person savings in HRQoL decline, total caregiver time, and total societal costs: for MCI: 1.5 points, 315 hours, and $2,638; for MILD AD: 2.0 points, 579 hours, and $3,974. Conclusions: Slowing AD progression over 36 months could slow decline in HRQoL and save caregiver time and societal cost in patients with MCI and MILD AD.

Published: June 2024

Background: The identification of biomarkers for different dementias in plasma and cerebrospinal fluid (CSF) has made substantial progress. However, they are observational studies, and there remains a lack of research on dementias with low incidence rates. Objective: We performed a comprehensive Mendelian randomization to identify potential biomarkers for different dementia type. Methods: The summary-level datasets encompassed 734 plasma and 154 cerebrospinal fluid proteins sourced from recently published genome-wide association studies (GWAS). Summary statistics for different dementias, including any dementia (refering to any type of dementia symptoms, 218,792 samples), Alzheimer’s disease (AD, 63,926 samples), vascular dementia (212,389 samples), frontotemporal dementia (3,024 samples), dementia with Lewy bodies (DLB, 6,618 samples), and dementia in Parkinson’s disease (216,895 samples), were collected from large GWAS. The primary method is inverse variance weighting, with additional sensitivity analyses conducted to ensure the robustness of the findings. Results: The molecules released into CSF, namely APOE2 for any dementia, APOE2 and Siglec-3 for AD, APOE2 for vascular dementia, and APOE2 for DLB, might be potential biomarkers. CD33 for AD and SNCA for DLB in plasma could be promising biomarkers. Conclusions: This is the first study to integrate plasma and CSF proteins to identify potential biomarkers for different dementias.

Authors: Shamsi Anas , Furkan Mohammad , Khan Mohd Shahnawaz , Yadav Dharmendra Kumar , Shahwan Moyad
Published: June 2024

Background: HMGCS2 (mitochondrial 3-hydroxy-3-methylglutaryl-COA synthase 2) plays a pivotal role as a control enzyme in ketogenesis, and its association with the amyloid-β protein precursor (AβPP) in mitochondria implicates a potential involvement in Alzheimer’s disease (AD) pathophysiology. Objective: Our study aimed at identifying repurposed drugs using the DrugBank database capable of inhibiting HMGCS2 activity. Methods: Exploiting the power of drug repurposing in conjunction with virtual screening and molecular dynamic (MD) simulations against ‘HMGCS2’, we present new in-silico insight into structure-based drug repurposing. Results: The initial molecules were screened for their binding affinity to HMGCS2. Subsequent interaction analyses and extensive 300 ns MD simulations were conducted to explore the conformational dynamics and stability of HMGCS2 in complex with the screened molecules, particularly Penfluridol and Lurasidone. Conclusions: The study revealed that HMGCS2 forms stable protein-ligand complexes with Penfluridol and Lurasidone. Our findings indicate that Penfluridol and Lurasidone competitively bind to HMGCS2 and warrant their further exploration as potential repurposed molecules for anti-Alzheimer’s drug development.
Contribution of system elements to its static indeterminacy
Authors: Perelmuter Anatolii
Published: June 2024

The article contains an overview of the main ideas regarding the new direction of construction mechanics, which considers the issue of survivability and is intensively developing. From the point of view of redundancy, as the ability of the system to provide alternative ways of transferring the load, which is one of the main possible strategies for designing reliability and survivability, the static-kinematic analysis of rod systems is also considered.
The fundamental measure of the level of redundancy of rod systems is the degree of static uncertainty. But this numerical sign does not contain information about the role of each element of the system in forming the degree of static uncertainty. This role is performed by a specially constructed distributed static indeterminacy matrix (DSI-matrix), which contains comprehensive information about the contribution of system elements to its static and kinematic properties.
Using the fundamental provisions of linear algebra, the properties of the matrix of coefficients of the system of linear equilibrium equations as an operator over the vector spaces of forces and displacements are analyzed. The mechanical content of the four fundamental subspaces associated with this matrix is indicated. This analysis determines the mathematical properties of the RSN matrix and its mechanical interpretation.
Methods of forming the DSI-matrix are considered both for the case of a geometrically constant system and for the analysis of geometrically variable systems, when it is necessary to resort to singular decomposition of the matrix of equilibrium equations. All theoretical explanations are accompanied by illustrative examples, although the issue of numerical implementation of the considered methods of analysis is not considered. It is obvious that they deserve independent consideration.
Information is provided on the possibility of using the DSI -matrix to assess the reliability and survivability of the structural complex and its use to analyze the sensitivity of the system to the inaccuracy of manufacturing elements.

According to the results of this work, it was established that the heating of the structure at all levels was uniform in the planes of placement of thermocouples, the maximum temperature on the surface was 709 °C, it was observed at the last minute of the experiment and continued to increase linearly, the maximum temperature reached in the center of the rock column was 105 °C, it was observed at the last minute of the experiment and continued to grow linearly; The adequacy of the experimental data was confirmed: the relative deviation did not exceed 4%, and the calculated adequacy criteria (Fisher, Student and Cochrane) were below the critical value.
Multi-criteria parametric optimization of the displacement and weight of a shell of minimal surface on a circular contour consisting of two inclined ellipses under thermal and power loading with consideration of geometric nonlinearity
Authors: Ivanchenko Hryhorii , Koshevyi Oleksandr , Zatyliuk Gherman
Published: June 2024

Thin shells are well suited to optimal design problems, and the finite element method and gradient descent method make it possible to solve inverse problems in structural and applied mechanics. The calculation process takes into account geometric nonlinearity.
In modern numerical studies, a formulation taking into account geometric nonlinearity in the finite element method is used, namely, a stepwise loading procedure. It becomes necessary to take into account the relations between displacement vectors and their derivatives and strain increments. These relations help to determine the stiffness matrix of the finite element at each loading step, which leads to a qualitative study of real displacements in the structure.
The geometrically nonlinear calculation of a shell of minimum surface on a circular contour consisting of two inclined ellipses in a multi-criteria parametric optimization is performed by the finite element method. The finite element method is a universal variational method that is focused on solving the most complex problems of elasticity theory and applied and structural mechanics using separate calculation complexes.
Stiffness matrix - for the whole body is formed on the basis of the finite element stiffness matrix. The system of solving equations of the finite element method is formed using the Lagrange's variational principle, according to which the total potential energy P of a finite element model of a body in a state of stability and equilibrium has a minimum value.
As part of the sensitivity analysis, gradients of the design variables of the structure, displacements in the form of partial derivatives of these characteristics along the design variables, and shell thickness are calculated. The sensitivity information serves as the basis for building an optimal design algorithm using the gradient descent method of the objective function.
Standard multi-criteria parametric optimization allows for an average of 10% steel savings, with geometric nonlinearity increasing to 20%. At this study site, 24.4% of sheet steel was saved, which is a significant relative saving.
This methodology of the authors shows high results for innovative design and production of steel thin shells in Ukraine and around the world, and also makes it possible to apply several types of optimization to one research object.

Published: June 2024

For the first time, comprehensive experimental studies of the influence of hydrogen and sulfur on sulphide stress corrosion cracking (SCR) of pipe steels in a corrosive-aggressive environment of NACE were carried out. In the research, experimental steels of the 06G2BA and 08KHMCHA brands, which are widely used in the construction of pipelines for various purposes, were used an analytical system (analyzer of non-stationary processes – ANP) was developed and tested in laboratory conditions, into which the installation for tests on corrosion-mechanical cracking under stress was integrated. For the first time, comprehensive experimental studies of pipe steel samples of grades 06G2BA and 08KHMCHA under the influence of sulfur and hydrogen were carried out, which made it possible to develop an understanding of the mechanisms of SCDS (sulphide-corrosion destruction under stress) and HID (hydrogen-initiated destruction). For the first time, experimental studies of the corrosion kinetics of 06G2BA and 08KHMCHA steels were carried out depending on the duration of the tests in the NACE model environment, while three periods of the formation of corrosion products were determined. It was found that sulfur and hydrogen, which are dissolved in test pipe steels, have a strong influence on the growth rate of corrosion cracks of SCDS, which made it possible to determine the optimal content of sulfur and hydrogen in steel 06G2BA. It is shown on the basis of the results of experimental studies that to ensure high crack resistance of pipe steels under conditions of static and cyclic loads both in air and in conditions of corrosive-aggressive environments, the sulfur content should not exceed 0.015-0.020%, and the dissolved hydrogen content should not exceed 2-3 ppm . The obtained results make it possible to improve pipe steels in the process of their smelting at metallurgical enterprises thanks to the use of economical modification with niobium, chromium, cerium and other impurities, which contribute to the fragmentation of the structure and reduce the content of non-metallic inclusions and harmful impurities.

Published: June 2024

The purpose of this paper is to examine self-leadership and its antecedents through a self-determination theory framework in order to identify and understand the key mediators that contribute to the development of self-leadership. Two studies were used to test the tenability of our proposed model across two domains. Study 1 examined self-leadership amongst a sample of undergraduate students. Study 2 examined a similar model amongst equine athletes from across Canada. Self-report questionnaires were employed to collect all data. Based on the conclusions, we suggest that autonomous motivation, rational decision-making and emotional regulation are important aptitudes for the development of efficient self-leadership. Ultimately, the research expands the literature on both self-determination theory and self-leadership by offering a unique multiple mediation models for predicting self-leadership development.

Published: June 2024

The spread of internet enhancing connectivity through various social media platforms has transformed the previous patterns of self-construction. The advent of the virtual world and digital culture has enabled individuals to be the creators and authors of their self or identity construction, especially in the digital world in contemporary society. In today's world, individuals’ personalities are divided into dualistic categories, the actual self-constructed through face-to-face interaction in the real world and the cyber-self which one has constructed through online interaction with people in the virtual world. In this study, the researchers tried to discover how men and women are inversely forming their digital or cyber selves in a male-dominated society and whether are they facing any specific coercion, threats, pros, and advantages because of their particular gender. Under the interpretive approach the researcher opted for qualitative research methodology and interviewed 20 individuals, with age ranged between 25 to 30 years, having virtual existence for the last ten years. The research findings indicated that women have to face similar barriers to the actual culture in the digital culture too. While constructing their cyber-self, women have to face discrimination just because of their gender by their male family members particularly.

Limbah yang dihasilkan dari pertambangan tersebut memiliki dampak negatif terhadap lingkungan jika tidak ditangani dengan baik. Limbah tailing mengandung logam merkuri dan unsur sianida yang dapat meracuni tanaman, hewan dan manusia. Untuk itu dilakukan upaya untuk mengembalikan kondisi tanah seperti semula, khususnya dengan melakukan revegetasi menggunakan tanaman Falcataria moluccana. F. moluccana dapat tumbuh diberbagai jenis tanah. Pertumbuhan tanaman F. moluccana pada tanah bekas tambang emas yang kurang subur membutuhkan bahan organik yang dapat memberikan nutrisi bagi tanaman, seperti pemberian pupuk kompos. Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh dan komposisi terbaik kompos pada tanah bekas tambang emas untuk memacu pertumbuhan semai F. moluccana. Metode yang digunakan yaitu metode eksperimen dengan menggunakan rancangan acak lengkap (RAL) non faktorial, yang terdiri dari 4 perlakuan dan 5 ulangan sehingga dihasilkan 20 unit percobaan. Hasil penelitian menunjukkan pemberian pupuk kompos berpengaruh terhadap pertumbuhan semai F. moluccana. Komposisi perlakuan D4 (pupuk kompos 75% + tanah bekas tambang emas 25%) menunjukkan pertumbuhan terbaik dengan hasil persen hidup 100%, pertambahan tinggi 26,75 cm, pertambahan diameter 2,66 mm, berat kering tanaman 6,90 g dan rasio tajuk akar 5,99. Pemberian kompos dengan dosis 75% dapat memberikan unsur hara yang optimal serta dapat memperbaiki struktur tanah bekas tambang emas dengan baik.

El Síndrome de Hipoventilación Central Congénito (SHCC) es una condición genética infrecuente que afecta el sistema nervioso autónomo y centro respiratorio por mutaciones en el gen PHOX2B, se asocia a hipoventilación alveolar durante el sueño y muerte súbita. Requiere tempranamente de ventilación mecánica invasiva (VMI).Objetivo: Reportar un caso neonatal tratado exitosamente con soporte ventilatorio no invasivo (SVNI), evitando la traqueostomía.Caso Clínico: Recién nacido de término, cuya madre utiliza SVNI nocturno por SHCC. Durante el periodo de transición presentó desaturaciones asociadas a hipercapnia y acidosis respiratoria, sin compromiso pulmonar. Evolucionó con hipoventilación severa durante el sueño, sin esfuerzo respiratorio, saturación periférica de oxígeno (SpO2) < 80%, más acidosis respiratoria. En vigilia presentaba buen esfuerzo respiratorio y SpO2 normales sin asistencia. La presión positiva continua no invasiva en la vía aérea y la oxigenoterapia empeoraban su condición al dormir. El SVNI completo con interfaz nasal y presión positiva en 2 niveles, presión inspiratoria/espiratoria 14-16/4 cm H2O, normalizaron la SpO2 durante el sueño y los gases en sangre arterial en vigilia. La secuenciación del gen PHOX2B confirmó la presencia de una variante patogénica heterocigota con el genotipo 20/26. A los 2 meses de vida egresó manteniendo SVNI con interfaz nasal y PEEP 0, logrando neurodesarrollo adecuado.Conclusión: Resaltamos la importancia del diagnóstico genético del SHCC, en neonatos con presentación clínica de hipoventilación alveolar temprana, particularmente si existe el antecedente familiar. No conocemos otros reportes de debut neonatal en que el SVNI evite la VMI, en esta patología potencialmente letal.
