Rayleigh-bѐnard convection in a second-order fluid with maxwell-cattaneo law

Abstract: The objective of the paper is to study the Rayleigh-Bѐnard convection in second order fluid by replacing the classical Fourier heat law by non-classical Maxwell-Cattaneo law using Galerkin technique. The eigen value of the problem is obtained using the general boundary conditions on velocity and third type of boundary conditions on temperature. A linear stability analysis is performed. The influence of various parameters on the onset of convection has been analyzed. The classical Fourier flux law over predicts the critical Rayleigh number compared to that predicted by the non-classical law. The present non-classical Maxwell-Cattaneo heat flux law involves a wave type heat transport(SECOND SOUND) and does not suffer from the physically unacceptable drawback of infinite heat propagation speed. It is found that the results are noteworthy at short times and the critical eigen values are less than the classical ones. Over stability is the preferred mode of convection.

Marketing agility and E-Commerce agility in the light of COVID-19 pandemic: A study with reference to fast fashion brands

Abstract: The purpose of this article is to explore the present COVID-19 crisis, which has affected fast-fashion. Global fast-fashion consumers have lost hope to revamp their wardrobe due to the broken supply chain network and the fear to visit the stores for purchase. The research intends to provide a detailed framework for the fast-fashion brands to strategically plan for post-COVID-19 business normality leading to sustainability. For the development of the model, careful investigation of the articles was carried out. This research is purely qualitative in nature depending on secondary data.In the post-COVID-19, the e-commerce industry will boom and those fast-fashion brands, which are already in the e-commerce platform, have to know the Percentage of Concentration (POC) in which they have to concentrate so that there are no wastages and spillover effects. Hence, marketing agility and e-commerce agility becomes the foundation for fast-fashion brands if it has to recapture its leadership position in the post COVID-19 pandemic. Fast-fashions have to follow the art of rethinking to replan and reimplement new strategies to revamp the business.

Checklist of spiders from the sacred groves of northern kerala, india

Abstract: Sacred groves are important gene pools and the first major effort of the society to recognize and conserve biodiversity. In addition to preserving the biodiversity, they help in soil and water conservation. At present, the area covered by sacred groves in India is gradually declining owing to various socioeconomic factors. Like other groves of Kerala, Sacred groves of North Malabar region are also facing the threat of extinction from increasing anthropogenic activities. Sacred groves of Northern Kerala have rich and diverse flora that supports an important array of fauna. This study presents a checklist of the spider fauna in 15 the sacred groves. It is a pioneering study and no other studies done in this area. The sampling methods such as line transect method; handpicking in ground and strata, and beating were used to catch specimens. The caught specimens were preserved and identified to species and genus level using available literature. A total of 257 species of spiders belonging to 130 genera and 28 families were identified from the study area. The dominant family was Araneidae followed by Salticidae, Theridiidae, and Thomisidae, these families represent roughly the 47% of the total abundance. Five families were observed as rare in the study area with less than 2 individuals.

Performance Analysis of Novel Compact Octagonal Shaped Fractal Antenna for Broadband Wireless Applications

Abstract: Antenna plays an important role in any part of the communication system. It has to be designed very cautiously to provide improved system performance to meet the developments in wireless technologies with various design constraints such as small size, low cost, high data, low power consumption and wideband capabilities. Several efforts have been made by various investigators around the globe to amalgamate benefits of fractal structures with electromagnetic concepts and applications to reduce the size of the antenna without obstructing the performance of the antennas. This paper proposes a novel compact octagonal shaped broadband fractal antenna. The proposed antenna was designed on an inexpensive FR4-epoxy substrate and simulated using the High Frequency Structure Simulator. The antenna resonates in dual bands in 3.8 and 1 GHz with lowest return loss of − 32.80 dB and gain of 10.22 dB while maintaining the VSWR in the 2:1 level. Attempts have been made to reduce the size and improve the bandwidth using fractal concept and truncation of ground plane. The fabricated antenna was verified experimentally and the results are agreeing with the simulations. The point of attraction of this antenna is the use of single patch for broadband coverage with easy fabrication.
