Expression profiling of stress responsive genes in cell suspension of Elettaria cardamomum (L.) Maton under abiotic stress
Authors: Dharan Soumya S. , Sabu K. K.
Published: November 2023

Cardamom is an economically important spice, valued for its multiple utility from culinary to medical purposes. The plant is highly susceptible to both abiotic and biotic stresses. Despite the fact that several studies focusing on stress in cardamom have been conducted; a molecular analysis at the cellular level has not been reported. This study highlights the molecular response of homogenous population of cardamom cell suspension following the temperature and drought stresses for a short period of time (20 mins). Temperature stress at 30, 35, and 40°C caused a significant increase in the transient expression of genes, sHSP 17.8 and sHSP 17.9, which are molecular chaperones involved in protein folding coping with the heat stress response of plants. Drought stress with various concentrations of PEG 6000 has demonstrated only a little increase in the expression of transcription factors, WRKY 35 and WRKY 71. The study implies that sHSP 17.8 and sHSP 17.9 play a crucial role during heat stress, which is a major limiting factor for the cultivation of cardamom in lower altitudes where atmospheric temperature is usually high. But WRKY 35 and WRKY 71 genes are found not to have a high impact at the cellular level in response to drought stress in cardamom when it is exposed to a brief duration of drought. Understanding the molecular mechanism underlying abiotic stress response in cardamom will aid in developing elite varieties adaptable to lower altitudes and to cope with the frequent climatic variations.

Published: November 2023

This communication is the new report of the neotropical invasive Bondar's Nesting Whitefly (BNW) , Paraleyrodes bondari Peracchi (Hemiptera: Aleyrodidae)incidence in oil palm in India. A typical feature of BNW infestation is the presence of woolly wax nests on the abaxial surface of oil palm leaflets. The nesting whitefly population was observed to increase phenomenally on oil palm and within a year ie., from 2021 to 2022, a 100 per cent palm infestation was observed. During this period the intensity per palm increased by 24.49 per cent and per leaf increased by 63.28 per cent. Analysis of the partial mitochondrial cytochrome oxidase subunit 1 (CO1) sequences from adult specimens indicated 100% nucleotide identity with Bondar's Nesting Whitefly from coconut.

The experiment has been conducted to resolve the poor partitioning of dry matter towards rhizome by using plant growth regulators (PGRs). Therefore, two pot culture experiments were conducted during 2020-22 using the variety IISR Varada to investigate the eﬀects of foliar application of PGRs (6-BAP, cycocel, GA3 and PBZ at five diﬀerent concentrations viz. control, 50ppm, 100ppm,150ppm and 200ppm in three replications) on growth and yield. The experiment was laid out in Factorial CRD design under polyhouse condition. The results revealed that 6-BAP at 100ppm significantly increased the number of tillers, secondary rhizomes, tertiary rhizomes, length, diameter of rhizomes, and rhizome yield (322.3g/ plant) which is 240% more than the control.
Community farm school approach for coconut seedlings/juveniles through collaborative social actions
Authors: Anithakumari P. , Indhuja S. , Shareefa M.
Published: November 2023

Three Grama Panchayats in Kerala's Alappuzha district undertook community-level participatory action research in 2019–2021. A total of 90 coconut farmers participated in the adoption of ICAR-CPCRI technology to produce West Coast Tall (WCT) coconut seedlings that are resistant/tolerant to the root (wilt) disease at the community level. Partners included extension agents, coconut producers' societies (CPS) and clusters, women self-help groups (WSHGs), and agricultural labor organizations. The characteristics of technologies that are suggested for adoption in root (wilt) disease-aﬀected tracts, such as the scientific management of young coconut trees and the production of high-quality seedlings through community nurseries, challenge the idea of adoption. There are a lot of variances in the homestead gardens' marginal holdings, including expertise, the use of technology, and access to advisory services. Government agencies provided the majority of the seedlings and extension advisory services, emphasizing the necessity for FPO-based or private extension in the coconut growing industry. The coconut farmers' understanding has significantly improved as a result of the participatory interventions for managing seedlings. The participatory demonstration and community farm school (CFS) strategy is discussed in the paper as a way for homesteads to manage juvenile coconuts while integrating new ideas and fostering cross and reciprocal learning. Refining the current extension approach requires integrating new knowledge about the characteristics of seedling growth, future economic performance, and social evaluation of choices of technological, individual, and skill-oriented interventions in risk-prone areas with debilitating root (wilt) disease.
Features of adaptation of the population in difficult climate and natural environment conditions (on the example of research in the Altai Republic)
Authors: Maximova Svetlana Gennadyevna , Atyasova Natalya   Yuryevna
Published: November 2023

The authors discuss approaches to the definition of the concept of "adaptation", the interdisciplinary nature of this term is noted. Biological, sociological and psychological approaches to understanding the essence of the phenomenon of "adaptation" are distinguished. At the biological level, a violation of personality adaptation due to difficult climatic conditions can lead to the emergence of physiological diseases, exacerbation of existing chronic diseases; at the psychological level of adaptation – to depressive states, apathy, anxiety, mental disorders; at the social level – to disruption of professional activity, difficulties in communicating with other people, the formation of negative ways of organizing leisure. It is noted that observations of local residents are a valuable source of information about climate change, especially at the local level. The article presents the data of an empirical qualitative study, the purpose of which is to identify and analyze trends in climate change and the natural environment in the Altai Republic in the perception of the local population. A number of in-depth interviews were conducted with experts, local residents living in permafrost areas of the Altai Republic: in the villages of Kosh-Agach and Ulagan districts. The obtained results of a qualitative study indicate problematic aspects of adaptation of residents of the Altai Republic at the biological level: in the presence of chronic diseases (especially high blood pressure is common), the population rarely seeks medical help. Risks are also noted at the social level of adaptation: the life activity of the population of the Republic takes place in difficult working and everyday conditions, due to difficult climatic conditions, residents have to abandon animal husbandry, a traditional source of personal food and income, there is difficult access to the social infrastructure of settlements, including for constructive leisure. The psychological component of adaptation, on the contrary, works quite effectively: despite the difficult living conditions, respondents assess their life as good and for the most part do not want to change their place of residence. It is noted that successful human adaptation is an integrated approach that includes biological, psychological and social components of adaptation.
Control-Oriented Modeling for Flexible Aircraft
Authors: Duan Molong , Cesnik Carlos E. S. , Kolmanovsky Ilya V. , Vetrano Fabio
Published: November 2023

Flexible aircraft designs with high-aspect-ratio wings and lightweight structures are increasingly adopted to achieve improved fuel efficiency. To design a controller for a flexible aircraft, a low-order model of its dynamics that captures the aeroelastic behavior is needed. One approach to establishing such a low-order model is to extend the six-degree-of-freedom rigid aircraft model with additional elastic states. However, most of the existing models along these lines are based on simplified aerodynamics models (e.g., experimentally corrected aerodynamic coefficients), which limits the applicability of such low-order models in early design stages. In this work, a semi-analytical model of flexible aircraft is established through the combination of the dynamics of elastic body and the numerical linearization of high-order structure and aerodynamics models. The proposed model is derived in the body-fixed axes formulation, represents full flight dynamics (both longitudinal and lateral), and preserves the physical meanings for the states and all the derived terms. Static residualization is also adopted to enhance the model’s accuracy with a limited number of elastic states. Using the proposed approach, low-order semi-analytical models are exemplified for different complexity aircraft representations and verified against the corresponding nonlinear high-order models.
Optimal Mission Planning for Multiple Agile Satellites Using Modified Dynamic Programming
Authors: Lee Kimoon , Kim Dong-Jin , Chung Dae-Won , Lee Seonho
Published: November 2023

This paper aims to optimize imaging mission planning for multiple agile Earth observation satellites using a modified dynamic programming (MDP) algorithm. The mission planning problem is mathematically modeled using mixed-integer linear programming, which defines the objective function and constraints. An MDP algorithm is proposed to address the challenge of extended computation time inherent in typical deterministic dynamic programming, aiming to optimize the imaging scheduling problem. Numerical simulations are conducted under various target numbers and satellites in a relatively narrow mission area with a high target density. The simulation results illustrate the stage configuration and target observation sequence over time, and this paper investigates the achievement rate, measured as the ratio of obtained profit and target observations to the total. The trend of computation time is also analyzed across all mission scenarios. Ultimately, the validity of the MDP algorithm is confirmed, as it demonstrates superior performance compared to the genetic algorithm, the branch-and-bound method, and the greedy algorithm.

The variability of the number of pores that appeared under the influence of additional introduction of the pore-forming material into the welding zone was analyzed. The Pearson test showed that Poisson's law adequately describes the variability of the number of pores in a unit area of the weld. At the same time, the experimental distribution is very close to the theoretical one calculated according to Poisson's law. The mathematical expectation of the number of pores in a unit area of the weld unambiguously determines the distribution of the number of pores. The form of the distribution depends significantly on the value of the mathematical expectation

Do all roads lead to Rome? Convergence issues in umbrella sampling simulations
Authors: Aho Noora , Groenhof Gerrit , Buslaev Pavel
Published: November 2023

Molecular dynamics (MD) simulations are widely applied to estimate absolute binding free energies of protein-ligand and protein-protein complexes. A routinely used method for binding free energy calculations with MD is umbrella sampling (US), which calculates the potential of mean force (PMF) along a reaction coordinate. In this work, we investigate the convergence of US along standard distance-based reaction coordinates for various protein-protein and protein-ligand complexes, following commonly used guidelines for the setup. We show that repeating the complete US workflow can lead to differences of 2-20 kcal/mol in computed binding free energies. We attribute those discrepancies to small differences in the binding pathways. We then demonstrate that adaptive-biasing approaches, which are constructed to sample multiple pathways in a single simulation, such as the accelerated weight histogram (AWH) method, can achieve convergence between independent simulations. To the best of our knowledge, this is the first attempt to systematically assess the shortcomings of the widely accepted protocols for US of protein-protein and protein-ligand binding affinities. We anticipate therefore that our results will provide an incentive for a critical reassessment of the validity of PMFs computed with US, as well as adopt adaptive-biasing approaches for computing binding affinities.
On the Dye-Protein Interaction of TMR-Biocytin – Streptavidin Complex: Molecular Simulations and Time-Resolved Fluorescence Quenching
Authors: Yoo Jang Mok , Lee Sujin , Kim Hahkjoon , Rhee Young Min
Published: November 2023

The interaction of a fluorophore and a protein, as a type of chemical-protein interactions (CPIs), is important toward studying physical properties of a protein through spectroscopy. For example, the structural changes of a protein can often be followed with spectroscopic tools by utilizing such an interaction. Streptavidin-bound 5-(and-6)-tetramethylrhodamine (TMR) biocytin is one of the few systems with which CPI can actually be observed via the fluorescence of TMR. While it has been suggested that the fluorescence is quenched when the ligand is bound to the binding pocket of streptavidin and is recovered after biotin occupies the binding pocket to replace TMR, no clear evidence has been provided yet. In order to gain a better understanding of this CPI, here we propose a possible binding site of TMR in the streptavidin, and predict the binding affinity values of biotin and the TMR moiety of TMR-biocytin conjugate. We estimate that the biotin affinity (-20.2 ± 1.4 kcal/mol) is significantly higher than the TMR-biocytin affinity (-6.91 ± 0.72 kcal/mol and -8.06 ± 0.79 kcal/mol), which supports the earlier explanation on the fluorescence quenching and recovery of biotinylated dyes. We also discover that TMR cannot bind to the streptavidin pocket as perfectly as biotin does, but that it rather blocks the entrance portion of the binding pocket. Fluorescence quenching of TMR-biocytin by streptavidin is measured with time-resolved fluorescence to show that the average fluorescence lifetime of TMR-biocytin decreases from 3.54 ns to 2.54 ns in the presence of excess streptavidin. Based on the distance between TMR and the nearby tryptophan residues, we propose that the nearby tryptophan residues of streptavidin are the potential quenchers of the dye unit fluorescence.
Operando Nuclear Magnetic Resonance (NMR) studies of a Trickle-bed Reactor using D-T2 Correlations
Authors: Sparks Amy , Mantle Mick , Brennan Colin , Gladden Lynn
Published: November 2023

Catalytic conversions in fine-chemical and pharmaceutical production are increasingly performed in trickle-bed rectors. Optimisation of these processes is usually based on end of pipe measurement made at specific residence times. This process is both time-consuming and the data sometimes challenging to interpret. In the present work, operando nuclear magnetic resonance (NMR) techniques both at the scale of the whole bed (global) and spatially-resolved within the bed (local) are used to gain new insights to the catalytic conversion process under reaction conditions. Spatially resolved spectroscopic and diffusion-T2-relaxation (D-T2) methods interrogate local differences in chemical conversion and selectivity, and mass transport (molecular self-diffusion) respectively, thereby providing valuable information for process simulation models. This capability is demonstrated using the continuous flow three phase (gas-liquid-solid) hydrogenation of benzonitrile over a fixed bed of 0.5 wt.% Pd/Al2O3 catalyst pellets yielding toluene and benzylamine. Global 1H spectroscopic and D-T2 were used to monitor chemical conversion and the approach to steady state; these were subsequently followed by spatially resolved 1H spectra and spatially resolved D-T2 correlations to examine the local differences in axial conversion and selectivity of the catalyst bed packing. At steady-state a global conversion of 63% was achieved with 65% and 25% selectivity to benzylamine and toluene respectively. Heterogeneities in the local (axial) conversion and selectivity differed by 31% along the total catalyst bed length. These techniques should be applicable to many three-phase heterogeneous catalytic systems provided that the T2 relaxation time of the reactants and products is not prohibitively small.
¿Equidad o brecha? Mujeres en revistas latinoamericanas de comunicaciones en acceso abierto en Scopus
Authors: Perdomo Bexi
Published: November 2023

Se planteó una investigación con el objetivo de estudiar la presencia de mujeres autoras de artículos científicos en revistas latinoamericanas de comunicaciones, tanto en los de autoría individual como en trabajos colectivos. Se analizaron 206 artículos de investigación publicados en dos revistas latinoamericanas indexadas en Scopus, de acceso abierto y que solo publican sobre comunicaciones. Los resultados mostraron 441 autores (54 % hombres y 46 % mujeres). Los hombres tuvieron mayor presencia como autores de artículos individuales. En los de autoría múltiple, las mujeres prevalecen en el primer lugar de autoría (hombres n = 60; mujeres n = 75) y en el tercero (hombres n = 6; mujeres n = 8), mientras que los hombres prevalecen en el segundo (hombres n = 70; mujeres n = 65) y el último (hombres n = 49; mujeres n = 31). La prueba de Chi cuadrado (p < ,05) mostró una asociación estadísticamente significativa entre el género y la posición en las autorías múltiples. Se concluye que, si bien existe inequidad de género en los artículos sobre comunicaciones, la brecha es menor que la reportada por los autores en otras áreas de conocimiento.
Motivating Tacit Knowledge Sharing: The Role of Perceived Value of Knowledge and Organizational Citizenship Behavior
Authors: Mahmood Ayyaz , R Tasmin , Saeed Bilal , Nguyen Mai , Hafeez Aamer
Published: November 2023

Purpose: This study investigates the challenge of retaining and sharing tacit knowledge during employee transitions in organizations, with a specific focus on software developers' motivations. We examine two key motivational beliefs: the perceived value of knowledge and organizational citizenship behavior (OCB), and their influence on sharing intentions. Additionally, we explore how these beliefs shape attitudes, subsequently affecting intentions regarding tacit knowledge sharing.
 
Theoretical Framework: Grounded in the Theory of Reasoned Action (TRA), our research underscores the pivotal role of beliefs in shaping attitudes and intentions related to tacit knowledge sharing. Beliefs, encompassing the Perceived Value of Knowledge and OCB, play a significant role in molding attitudes. Using structural equation modeling, we analyze data collected from 197 software developers, employing confirmatory factor analysis to validate our measurement model and structural model analysis to explore relationships.
 
Findings: Our findings indicate that software developers are indeed willing to share their tacit knowledge, with their willingness positively influenced by the perceived value of tacit knowledge and engagement in OCB. Attitudes towards sharing tacit knowledge act as mediators in the relationship between these beliefs and sharing intentions.
 
Implications: In practical terms, organizations can foster tacit knowledge sharing by promoting positive attitudes, recognizing knowledge's perceived value, and cultivating a culture that encourages OCB. This facilitates a conducive environment for sharing, further enhanced by acknowledging and rewarding employees who exhibit OCB. Theoretical implications align with the Theory of Reasoned Action, emphasizing the role of attitude in shaping intentions. Our research contributes uniquely by exploring the underrepresented relationship between perceived knowledge value and tacit knowledge sharing, introducing a novel approach by examining the combined impact of OCB and perceived value. These insights are valuable for organizations looking to cultivate a culture of tacit knowledge sharing, driving innovation and enhancing performance.

Published: November 2023

Manipulation in translation is generally seen as the linguistic manifestation of intervening strategies meant to hide or change the true intentions. It is broadly defined as “all that appears as new with respect to the original, or fails to appear where it might have been expected.” Aspects of the manipulative lineament of translation, particularly of political and diplomatic discourse, have been held forth by a host of scholars, many of whom advise that translation should be studied within a broader political and cultural context, with regard to institutional and ideological components.

Background: Acceptability of COVID-19 vaccine by healthcare workers (HCWs) can affect its acceptability by the general population. Aim: To assess COVD-19 vaccine acceptability among HCWs in Sana’a, Yemen. Methods: We conducted a multicentre cross-sectional study among 391 HCWs in Sana’a, Yemen, from January to March 2022. We used a self-administered questionnaire to collect data on the demographics, profession, academic qualifications, and experience of HCWs, as well as their COVID-19 vaccine acceptability or hesitancy. We used univariate and multivariable logistic regression to analyse the association between the independent variables and vaccine hesitancy (P < 0.05). Results: Of the 391 HCWs, only 194 (49.6%) were willing to accept the COVID-19 vaccine. The most frequent reasons for vaccine hesitancy were fear of adverse reactions (77.7%), concerns about unknown effects of the vaccine in the future (73.1%), and uncertainty about the safety of new vaccines (69.5%). Female gender and working in the public sector were independent predictors of vaccine hesitancy among the HCWs. Conclusion: Nearly half of the HCWs in Sana’a, Yemen, were willing to accept the COVID-19 vaccine. Female gender and working in the public health sector were independent predictors of vaccine hesitancy. We recommend further studies to compare COVID-19 acceptability among HCWs in the public and private sectors in Yemen.
