Polycrystalline samples of Y1-xSmxCrO3 (0 ≤ x ≤ 0.3) are synthesized through an ethylene glycol-assisted sol-gel auto-combustion route. All the samples crystallize in orthorhombic structure with Pnma symmetry. Magnetic measurement shows intriguing properties, i.e. spin reorientation (SR) followed by exchange bias (EB) effect below TSR. This result is attributed to competing interaction between the Sm and Cr below TSR. Moreover, magnetic transition temperature (TN) is shifted towards higher te...

This study explores a budget-friendly H-plane horn antenna based on a Substrate Integrated Waveguide (SIW) based technology for wideband applications. The antenna is designed using FR4 substrate material, which has a thickness of 1.6 mm. A small arc is placed at the front side of the antenna aperture for proper matching with the free space. It is found that the horn antenna can work from 6.39 to 19.15 GHz, which can cover X and Ku – bands. In addition, the flaring angle of the H-plane horn an...
Vehicle platooning is a cooperative driving technology that can be supported by 5G enhanced Vehicle-toEverything (eV2X) communication to improve road safety, traffic efficiency, and reduce fuel consumption. eV2X communication among the platoon vehicles involves the periodic transmission of Cooperative Awareness Messages (CAMs) containing vehicle information under strict latency and reliability requirements. These requirements can be maintained by administering the assignment of resources, in ...
Jojoba (Simmondsia chinensis), a drought-resistant crop, offers significant benefits in soil erosion mitigation, making it an ideal choice for sustainable agriculture in arid and semiarid regions. While the global demand for jojoba oil continues to grow due to its extensive industrial and cosmetic applications, the oil extraction process generates a largely underutilized, protein-rich by-product: jojoba oilcake. This study investigates the extraction and characterization of jojoba proteins, h...
Purpose: The current ecological challenges and energy crises require adopting GH practices for sustainable development. Green Healthcare Initiatives (GHI) consistently emphasizes enhancing healthier indoor environments for its stakeholders by advocating for environmentally friendly cleaning agents, improving indoor air quality, and minimizing exposure to hazardous substances. This study aims to analyze and prioritize the factors inhibiting the implementation of GHI in the healthcare sectors o...
The present study aims to analyze the available Ocean Model Intercomparison Project Phase-2 (OMIP2) models from the Coupled Model Intercomparison Project Phase-6 (CMIP6) group in representing the seasonal mean variations of temperature and salinity. The skill of the models in representing seasonal mean biases of temperature and salinity is assessed with World Ocean Atlas and Argo observations over the Tropical Indian Ocean (TIO), Bay of Bengal (BoB), Arabian Sea (AS), and Southern Indian Ocea...
Iron oxide nanoparticles (IONPs) have been extensively studied for drug/gene delivery, biomedicine, biosensing, and hyperthermia. Functionalizing IONPs with appropriate materials is still highly desired because of their various uses. To design the required functionalized IONPs, polydopamine (PDA) was used to accomplish optimal functionalization because of its sound, functionalized surface, capacity to absorb near-infrared light, and adhesive qualities. The effective attachment of PDA was conf...

Rice production is vulnerable to several pressures; one of the main biotic stresses is blast disease, which is brought on byMagnaportheoryzae and can potentially wipe out the entire crop under extreme circumstances. Microbial-mediated seed and root prime in plantsenhance defense against a broad range of pathogens by jasmonate (JA) and ethylene (ET) signaling mediated induced systemicresistance (ISR). The present work demonstrates some selected microbes like Bacillus cereus, Pseudomonas aerugi...
A significant rice disease known as "rice blast" can reduce crop yield by up to 30%, which has an impact on world food security. Numerous investigations into finding the genes responsible for disease resistance in previously resistant cultivars failed to find a solution to eradicate the illness from the field. Nonetheless, certain plants found in nature are known to be non-hosts and are not afflicted by the rice blast pathogen. In opposition to a pathogen race, a non-host plant offers broadsp...
Access to credit plays a pivotal role in the growth trajectory of firms; however, Micro, Small, and Medium Enterprises (MSMEs) in emerging economies face myriad challenges that hinder their full potential. Therefore, The primary objective of this research is to explore the association between bank credit and trade credit, considering the moderating influence of firm tangibility within the realm of Indian manufacturing MSMEs. Using a robustly balanced panel dataset comprising manufacturing MSM...
Rice is grown extensively in many parts of the world at different times of the year under different climatic conditions. Rice is the most essential cereal crop that forms a major part of the human diet and is hence popularly called "Global grain". With the increasing trend of the rising human population, it’s high time to have crops with high yield potential and stability. Making the rice-based production system sustainable is crucial for the future food security of mankind. Rice blast is one...
In this paper, a Band Pass Frequency Selective Surface (FSS) is presented with an aperture-coupled single band fourth order. Firstly, a pair of square and triangular truncations are introduced in a square patch along the rightside diagonal and left-side diagonal, respectively, forming a structure that appears as two tilted hexagons cascaded together. With simultaneous excitation, the symmetry of this structure introduces two orthogonal degenerative modes. However, perturbations in the form of...
