Ebcqi: Enhanced bcqi downlink scheduling algorithm for voip in mobile networks
Long Term Evolution (LTE) is a currently growing technology. It gives high speed data with several useful applications. Voice over Internet Protocol (VoIP) is one of the top most applications in that LTE. Scheduling is the main issue in LTE. This paper proposing an updating version of Best Channel Quality Indicator (BCQI) downlink scheduling algorithm. The proposed algorithm assigns the highest priority to VoIP users followed by video traffic and then other remaining traffics in next priority order. The simulation reports give the better results of increased average throughput in all users, as well as the spectral efficiency development is also increased. Here, in the proposed algorithm, the percentage of packet loss is also consistent with the existing BCQI algorithm. And, it totally emits positive results in both rural and urban area environments with different mobility. Number of user access is also high when compared with BCQI algorithm. IJSTR 2019. -
EC(H) onarrating stories: Ecological thought and metanarrativity in folktales
This paper studies the ecological discourse constructed in folktales, looking at the relationship between folktales and the human-nature-culture paradigm. By closely examining select folktales collected by folklorist A. K. Ramanujan, this paper looks at the metanarrativity of tales and argues from a narratological perspective that folktales deploy nature metaphors to establish a close relationship between nature, women and culture. This, it is argued, is made possible only in the conservation of stories for, in conserving a story, the message of conserving cultures and their artefacts (an ecological metaphor) is spread. The story is conserved; however, not in hoarding it but quite contrarily in transmitting and letting it go. The paper also critically examines how female subjects, through the use of nature metaphors and symbols of fertility and femininity speak of their consciousness in these 'woman-centred tales' in a space characterized by the absence of the Phallic Other but inevitably speak the patriarchal language of feminine inscriptions. Using folkloric research of A. K. Ramanujan as well as ecocritical frameworks, this paper looks at the narratological dimensions of folklore to understand metanarration as a crucial aspect of folklore and ecological conservation. Therefore the lessons of conservation lie not only in the content of the folktales but also in their very telling. The ecological aspects in and of the tale must necessarily be echoed multiple times to enable the tale's transmission, and in effect, their conservation. 2014 Journal of Dharma: Dharmaram Journal of Religions and Philosophies (Dharmaram Vidya Kshetram, Bangalore). -
Ecc-based secure group communication in energy-efficient unequal clustered wsn (Eeuc-ecc)
With an advent of the Internet of things (IoT), wireless sensor networks (WSNs) are gaining popularity in application areas like smart cities, body area sensor networks, industrial process control, and habitat and environment monitoring. Since these networks are exposed to various attacks like node compromise attack, DoS attacks, etc., the need for secured communication is evident. We present an updated survey on various secure group communication (SGC) schemes and evaluate their performance in terms of space and computational complexity. We also propose a novel technique for secure and scalable group communication that performs better compared with existing approaches. Springer Nature Singapore Pte Ltd. 2020. -

Ecclesiology, piety, and presbyterian and independent polemics during the early years of the english revolution
Religious controversy swept across England during the revolutionary decades of the 1640s and 1650s. Historians have studied the attendant ecclesiological debates meticulously. The piety as practiced by the puritans has also been carefully examined. Yet generally, these two subjects of ecclesiology and piety have been kept as separate compartments of analysis. The plethora of tracts that rolled off the press during the initial years of the 1640s, nevertheless, shows that many contemporary polemicists were keen to tie the two themes together. The Presbyterian and Independent polemicists were no exception. As this article seeks to demonstrate, a common feature of their publications was the belief that their preferred ecclesiastical polity best served the purpose of promoting individual piety and creating a godly society. Thus the Presbyterian and Independent conflict waged not only over issues of ecclesiology proper such as categories of church offices and of governing councils or composition of church membership to which historians have directed their attention hitherto, but also over questions of how ecclesiology affected piety. Such conflict was a reflection of the commitment of Presbyterians and Independents to their respective vision of reformation for the country. More broadly, this article shows a facet of religious controversy that ultimately led to the disintegration of the godly community and weakened the base of support for the Commonwealth and the Protectorate.

Echoes of Conflict: Unveiling the Interconnected Tapestry of Russia-Ukraine Warfare, Oil Price Ballet, and the Asian Stock Symphony
The purpose of this research is to look into the impact of the Russia-Ukraine war on the relationship between oil prices and the Asian stock market. While earlier studies have investigated the impact of oil prices on stock markets, there has been little research into the impact of crude oil prices on the Asian stock market in the context of the Russia-Ukraine war. For this purpose, the data is collected from NSE and Bloomberg database the study's findings imply that the Russia-Ukraine war has had a major impact on the relationship between crude oil prices and stock market indices in numerous Asia-Pacific countries. The study suffers from a few limitations such as it only examines the relationship between crude oil prices and stock market indices but there are other macroeconomic factors, such as interest rates, inflation, and political instabil ity which also affect the market. 2024, ASERS Publishing House.

Eco friendly nitration of toluene using modified zirconia
Nitration of toluene has been studied in the liquid phase over a series of modified zirconia catalysts. Zirconia, zirconia- ceria (Zr0.98Ce0.02)O2, sulfated zirconia and sulfated zirconia- ceria were synthesised by co precipitation method and were characterised by X-ray diffraction, BET surface area, Infra red spectroscopy analysis (FTIR), Thermogravimetric analysis (TGA), Scanning Electron Microscopy (SEM), and Energy Dispersive X ray analysis (EDAX). The acidity of the prepared catalysts was determined by FTIR pyridine adsorption study. X-ray diffraction studies reveal that the catalysts prepared mainly consist of tetragonal phase with the crystallite size in the nano range and the tetragonal phase of zirconia is stabilized by the addition of ceria. The modified zirconia samples have higher surface area and exhibits uniform pore size distribution aggregated by zirconia nanoparticles. The onset of sulfate decomposition was observed around 723 K for sulfated samples. The catalytic performance was determined for the liquid phase nitration of toluene to ortho-, meta- and para- nitro toluene. The effect of reaction temperature, concentration of nitric acid, catalyst reusability and reaction time was also investigated. 2013 BCREC UNDIP. -
Eco-conscious photocatalytic degradation of organic textile dyes using green synthesized silver nanoparticles: a safe and green approach toward sustainability
Green synthesized nanoparticles from Strobilanthes barbatus leaf extracts are environmentally safe and feasible for enduring wastewater treatment, especially for organic textile dye degradation. The synthesized Strobilanthes barbatusmediated silver/silver-oxide nanoparticles (SB-Ag/AgO NPs) showed maximum absorbance at 428nm. The SB-Ag/AgO NPs were generally spherical with an average diameter of 37.59nm (FESEM and TEM analysis). The importance of functional groups in the production of SB-Ag/AgO NPs was recorded by FTIR investigations. In the degradation and rate of degradation for textile dyes, after 320min, SB-Ag/AgO NPs displayed 96.60% (5.31 10?1 L mg?1min?1) and 87.50% (1.179 10?1 L mg?1min?1) degradation of Reactive Blue 220 (RB-220) and Reactive Blue 222A (RB-222A), respectively. When compared to dye effluents, SB-Ag/AgO NPs-treated dye solutions revealed a considerable decrease in inhibitory efficiency during phytotoxicity evaluation on test organisms, Vigna radiata and Artemia salina. The biosynthesized SB-Ag/AgO NPs could serve as a feasible photocatalyst for the treatment of organic textile dyes in organic substancepolluted water ecosystems. SB-Ag/AgO NPs can serve as efficient, cost-effective and environmentally friendly sources for dye degradation. The current research offers a safe and environmentally friendly strategy for sustaining the environment. 2024, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature. -

Ecofriendly Approaches for Ameliorating the Adverse Effects of Cadmium in Plants by Regulating Physiological and Defense Responses: An Overview
Mitigating cadmium stress in agricultural plants becomes extremely critical in order to assure food sufficiency in the scenario of a rapidly growing population. An extensive review of environmentally friendly methods for reducing cadmium toxicity in plants is provided in this chapter, with special attention to a variety of tactics like phytohormones, polyamines, melatonin, mineral ions, nanoparticles, and transgenic techniques. Nanoparticles are capable of changing the distribution of cadmium, activating antioxidant defense mechanisms, and boosting physiological processes that are crucial for plant resilience and growth. Microorganisms greatly increase plant resistance to cadmium stress by modifying phytohormones and regulating defense-related proteins. Phytohormones can increase a plants adaptability to cadmium stress through a number of mechanisms, such as the regulation of gene expression and physiological processes. Melatonin and polyamines provide protection against oxidative stress and heavy metal toxicity, while mineral ions such as silicon, calcium, zinc, iron, and selenium increase plant resistance to cadmium, minimizing pollution-related harm. Transgenic plants that are tolerant to cadmium exhibit enhanced detoxification processes and reduced metal accumulation. These findings provide important insights for long-term plant cadmium mitigation and highlight the significance of interdisciplinary approaches in managing heavy metal stress in agricultural systems.

Economic globalization and unemployment: Evidence from high-, middle- and low-income countries
This study intends to empirically evaluate the effects of economic globalization and its components (i.e. trade and financial openness) on unemployment in high-, middle- and low-income countries from 1991 to 2020. Further, it considers real GDP per capita (sectoral divisions of income, i.e. agriculture, industry and service sector) and urbanization as control variables in the unemployment function. On the empirical front, this study employs the Panel Dynamic Simulated ARDL model and the Kernel-Based Regularized Least Squares for long-run influence estimations. The emanating outcome of these analyses states that economic globalization destroys employment opportunities for low-income countries as it enhances unemployment in the long run. However, in high- and middle-income countries, economic globalization creates employment, which implies reducing unemployment in the long run. The result also indicates that trade and financial openness destroy employment opportunities in low-income countries. Although trade openness in middle-income countries shows the same effect, financial openness does not mimic the same. For high-income countries, trade openness reduces unemployment, but financial openness fosters it. Therefore, these findings indicate that to keep unemployment at a low level, policies related to the opening up of the economy in terms of factor mobility, offshoring, outsourcing and international trade need to be implemented in low-income countries. Moreover, a similar consideration is needed for high and middle-income countries to avoid faraway repercussions on unemployment due to becoming a peripheral country. 2024 John Wiley & Sons Ltd.
