No full textRecently, the first author [1] showed that the admissible vector-valued
automorphic forms lift to the admissible ones. In this article, we study the
lifts for the logarithmic vector-valued automorphic forms and explicitly
compute the Fourier coefficients of the lifted vector-valued automorphic forms.Comment: 20 pages, revised following referee's suggestion
Silencio del Empleado Predicho por Liderazgo Abusivo y Ostracismo Laboral: Papel de la Distancia Jerárquica del Empleado
No full textThe proposed research aimed to examine abusive leadership and workplace ostracism as predictors of employee silence among school teachers in Sargodha, Pakistan. Studies further tend to examine the moderating role of power distance. Purposive sampling was employed to acquire the data. The research variables were quantified using the Abusive Supervision Scale (Mitchell & Ambrose, 2007), Workplace Exclusion Scale (Hitlan & Noel, 2009), Silence Scale (Van Dyne et al., 2003) and Power Distance Scale (Dorfman & Howell, 1988). Pearson correlation analysis revealed a significant relationship between abusive leadership, workplace ostracism, employee silence, and power distance. Results showed that abusive leadership, ostracism, silence, and power distance have a positive relationship with each other. The findings of linear regression revealed that abusive leadership, ostracism and power distance positively predicted employee silence. Moderation analysis revealed that power distance significantly moderated the relationship of abusive leadership and workplace ostracism with employee silence. The proposed research provides some recommendations and conclusions for future researchers who may be interested in examining the abuse that teachers experience in a high-power-distance culture that compels them to act silently.La investigación propuesta tuvo como objetivo examinar el liderazgo abusivo y el ostracismo laboral como predictores del silencio de los empleados entre los profesores de escuela en Sargodha, Pakistán. Los estudios también tienden a examinar el papel moderador de la distancia jerárquica. Se utilizó un muestreo intencional para adquirir los datos. Las variables de investigación se cuantificaron utilizando la Escala de Supervisión Abusiva (Mitchell & Ambrose, 2007), la Escala de Exclusión Laboral (Hitlan & Noel, 2009), la Escala de Silencio (Van Dyne et al., 2003) y la Escala de Distancia Jerárquica (Dorfman & Howell, 1988). El análisis de correlación de Pearson reveló una relación significativa entre el liderazgo abusivo, el ostracismo laboral, el silencio de los empleados y la distancia jerárquica. Los resultados mostraron que el liderazgo abusivo, el ostracismo, el silencio y la distancia jerárquica tienen una relación positiva entre sí. Los hallazgos de la regresión lineal revelaron que el liderazgo abusivo, el ostracismo y la distancia jerárquica predijeron positivamente el silencio de los empleados. El análisis de moderación reveló que la distancia jerárquica moderó significativamente la relación del liderazgo abusivo y el ostracismo laboral con el silencio de los empleados. La investigación propuesta proporciona algunas recomendaciones y conclusiones para futuros investigadores que puedan estar interesados en examinar el abuso que experimentan los profesores en una cultura de alta distancia jerárquica que los obliga a actuar en silencio
Short-chain n-alkanes in benthic mats and mosses from the Larsemann Hills, East Antarctica
No full textVariation in leaf colour (green, red and grey) of mosses and lake benthic mats in Antarctica is often linked to water stress and ultraviolet light (UV-B) exposure. Changes in the abundance of organic compounds, such as pectin and phenols, are associated with mechanisms protecting against desiccation and UV radiation. However, the function of n-alkanes, especially against UV radiation, is rarely examined. Here, gas chromatography–mass spectrometry and Fourier-transform infrared spectroscopy analyses were performed to study the variation in n-alkanes in freshwater lake benthic mats and mosses collected from the Larsemann Hills in East Antarctica. Stable isotopes of organic carbon and nitrogen, environmental DNA characterisation and microscopy-based analyses are used to estimate the presence of cyanobacteria, algae and diatoms in moss and benthic mat consortia. Variation in the short-chain (n-C17 to n-C20) versus long-chain (n-C21 to n-C30) n-alkanes in the mosses and benthic mats with their colour were noted. The research links the relative abundance of short-chain n-alkanes to the UV-B exposure and proposes that Antarctic mosses and benthic mats synthesise short-chain n-alkanes for protection against UV-B.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Sanitary Engineerin
Google Scholar Adoption by LIS Educators in India: An Exploratory Study
No full textGoogle Scholar (GS) is one of the popular online databases fulfilling the research needs of academicians by providing an open and freely accessible platform for searching scholarly research along with basic research metrics (citations, h-index, i10, etc.) to assess productivity of an author or researcher. Now that GS is being used to measure the research performance of individual’s as-well-as institutions, it becomes very important to maintain a verified profile. This paper aims to analyse dual inter-related issues. Quantify LIS schools in India are the primary focus area of the study. Secondly, the scenario of LIS educators of India under GS will be evaluated. It also presents the accurate status of Indian universities (government) imparting LIS education and to investigate how many faculties of those universities are using Google scholar account for showcasing their research productivity. The study unveils those educators (LIS) whose articles are scattering under GS database but due to unavailability of profile GS can’t compute scientometric data for them. As per the VIDWAN database - an expert database developed by INFLIBNET, many LIS educators do not have their own Google scholar ID. In India out of 470 govt universities about 129 have LIS schools. Total 324 LIS educators are recruited under those universities. Only 206 educators possess own GS profile. Hence, the GS profile adoption ratio between Indian LIS educators is not impressive. This study can give an overview of the above-mentioned dual topics in details latter
Application of Genetic Fuzzy System for Damage Identification in Cantilever Beam Structure
No full textAbstractThe performance of the system consisting of beam structures is very much affected by identification of faults or damage in it's structural integrity. The consistent and secure operation can be well ensured in an engineering system by effectively identifying the damage in the structures. The conventional techniques are rendered to few limitations due to the unreliable mathematical simulation used for actual scenario. Therefore, hybrid artificial techniques (AI) would be more sophisticated tool for damage identification in beam structures. The combination of Fuzzy inference system and Genetic algorithms (GAs) can be employed to obtain effective solutions for many systems. In the current research, GA-Fuzzy controller has been considered for identification of damage in steel cantilever beam in transverse direction subjected to natural vibration. The results obtained from the proposed technique have been in very good agreement with the experimental results
Coupled effects of wind shear and bed absorption on sediment transport in wetland
No full textWetlands play a vital role in sustaining ecosystems, supporting biodiversity, and controlling environmental degradation. Sedimentation in wetlands has emerged as a critical research area due to its relevance in flood management, water purification, and geophysical applications. Despite its importance, the combined effects of wind shear and bed absorption on sediment transport remain underexplored. This study investigates sediment removal efficiency in wetland flow influenced by wind shear, absorbent beds, and particle settling. The time-dependent convection-diffusion equation is solved using a hybrid approach, combining Aris's method of integral moments with a finite difference implicit scheme. Analytical expressions for two-dimensional spatial concentration distributions are derived via Gill's series expansion. Key parameters, including wind direction (W), relative wind strength ( Er), bed absorption coefficient ( β), vegetation parameter ( α), and settling velocity ( ω), are analyzed to determine their impact on dispersion characteristics like the dispersion coefficient, concentration distribution, skewness, and kurtosis. Results show that wind shear enhances sediment dispersion when aligned with the flow ( W=+1) but induces backflow and reduces dispersion within a certain wind strength range when opposing it ( W=−1). Bed absorption accelerates stabilization by trapping particles, limiting their dispersion capacity. Settling velocity further influences dispersion by reducing the suspension of the particles, with higher ω accelerating stabilization but suppressing long-term dispersion. Dense vegetation reduces wind-induced variations, improving flow stability by dampening momentum transfer. This study provides new insights into coupled wind-absorbent bed-settling velocity interactions, offering a framework for optimizing wetland design, pollutant removal, and environmental sustainability. This proposed model can be applied to optimize wetland restoration strategies, enhance sediment management in aquatic ecosystems, and improve pollutant filtration efficiency in natural and engineered water systems.The authors wish to express their sincere thanks to the Chief Editor, Associate Editor, and anonymous reviewers for their constructive comments and suggestions for the improvement of the present research.

How Did Research on Conservation Agriculture Evolve over the Years? A Bibliometric Analysis
No full textConservation agriculture has recently been a hot topic of agricultural research and has generated significant global interest. Conservation agriculture has three core principles: minimal soil disturbance, permanent soil cover, and crop rotations. The research on this topic has also witnessed a boom in recent years as the number of peer-reviewed literature on conservation agriculture is rising exponentially. This study critically examines all the peer-reviewed documents published on conservation agriculture from the 1990s to 2021 and indexed in the web of science core database. The search returned 3023 documents, which were then processed in the R-based bibliometric package for annual scientific production trend, source, author, document, citation, keyword analysis, and co-occurrence networking using VOSviewer. Our findings show remarkable growth in conservation agriculture research in recent times, although it witnessed a shortfall in 2021. Notably, 15 core source journals contribute the most to the field, while 8692 researchers have authored or co-authored at least a document on conservation agriculture. While the USA, India, and Australia are front runners in conservation agriculture research, the spread of the topic is worldwide
Nanotheranostics to target antibiotic-resistant bacteria: Strategies and applications
No full textVarious health agencies, such as the European Medical Agency (EMA), Centers for Disease Control and Prevention (CDC), and World Health Organization (WHO), timely cited the upsurge of antibiotic resistance as a severe threat to the public health and global economy. Importantly, there is a rise in nosocomial infections among covid-19 patients and in-hospitalized patients with the delineating disorder. Most of nosocomial infections are related to the bacteria residing in biofilm, which are commonly formed on material surfaces. In biofilms, microcolonies of various bacteria live in syntropy; therefore, their infections require a higher antibiotic dosage or cocktail of broad-spectrum antibiotics, aggravating the severity of antibiotic resistance. Notably, the lack of intrinsic antibacterial properties in commercial-grade materials desires to develop newer functionalized materials to prevent biofilm formation on their surfaces. To devise newer strategies, materials prepared at the nanoscale demonstrated reasonable antibacterial properties or enhanced the activity of antimicrobial agents (that are encapsulated/chemically functionalized onto the material surface). In this manuscript, we compiled such nanosized materials, specifying their role in targeting specific strains of bacteria. We also enlisted the examples of nanomaterials, nanodevice, nanomachines, nano-camouflaging, and nano-antibiotics for bactericidal activity and their possible clinical implications
