Antibacterial activity and spectroscopic characteristics of silver nanoparticles synthesized via plant and invitro leaf-derived callus extracts of Mucuna pruriens (L.) DC
In this paper, we describe the green synthesis of silver nanoparticles (AgNPs) using plant extracts, as well as their structural, optical, and antibacterial activities against Escherichia coli and Bacillus velezensis bacteria. For the study, several sections (root, leaves, and seed) of Mucuna pruriens, an immense medicinal herbal used to treat Parkinson's disease, were evaluated. Also, the seeds were grown in-vitro in the modified Murashige and Skoog's medium and the leaf derived callus supplemented by different phytohormones like picloram (pic), thidiazuron (TDZ), 6-benzylaminopurine (BAP) and 2-isopentenyl adenine (2-iP) were selected for this study. This is the first report of distinct callus obtained from M. pruriens and used for green nanoparticle synthesis. The prepared materials were thoroughly evaluated for structural and optical properties using XRD, FTIR, and UV-Visible spectroscopy. During synthesis, the colour changes from colourless to reddish brown, and the existence of an SPR peak in the absorption spectra confirms the formation of AgNPs. The FTIR spectra reveals the presence of phenolic group and alkyl ether groups, which were responsible for the reduction of silver ions during the green synthesis. The aqueous extracts of plant parts and callus obtained from different hormones showed very poor antibacterial activity. However, the green synthesized nanoparticles fabricated by different plant extracts showed good antimicrobial activity towards E. coli and B. velezensis bacteria. amongst the investigated results, highest antimicrobial activity against E. coli (84.8%) and B. velezensis (78.1%) was shown by AgNPs mediated by leaf extracts respectively followed by 0.5 mg/L pic and 2.0 mg/L BAP callus mediated silver nanoparticle solution. According to the findings, green produced AgNPs are promising candidates for antibacterial applications against E. coli and B. velezensis. 2022 SAAB -

INVESTIGATING THE ROLE OF UTAUT2 IN THE USER SATISFACTION AND CONTINUED USAGE OF MOBILE FITNESS APPS: EVIDENCES FROM INDIA
This study examines mobile fitness app (MFA) adoption and use using the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2). CB-SEM analysis of 445 respondents through IBM-AMOS was conducted. UTAUT2 constructs were examined including, consumer satisfaction, e-loyalty, and mobile fitness app reuse. Also, the roles of socio-demographic factors as control variables were examined. The results indicated that UTAUT2 significantly influenced user perception of MFAs. UTAUT2 constructs increased user satisfaction. User satisfaction positively and significantly influenced e-loyalty and app reuse. The study also suggests future research on UTAUT2's role on MFAs. The study highlights UTAUT2 by revealing the constructs that influence MFA adoption, and selected consequences. (2024), (Amity University). All rights reserved. -
Examining the moderating role of online celebrity trustworthiness and risk propensity in UTAUT2 framework: A mixed-method approach
Utilizing the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) framework, this research delved into the behavioral intentions and actual usage of fantasy sports gaming apps. The moderating influence of celebrity trustworthiness and risk propensity is also explored. The proposed hypotheses were tested using responses from a substantial sample of 460 sports fantasy gaming app users. The research deployed a mixed-method approach, combining both covariance-based and partial-least square structural equation modeling tech- niques. The investigation findings revealed an influence on behavioral intentions and actual use. Specifically, performance expectancy, hedonic motivation, habit, and social influence emerged as significant determinants affecting users intentions and behaviors. The study indicates a significant moderating role of celebrity trustworthiness on the relationship be- tween performance expectancy, hedonic motivation, habit, and social influence concerning behavioral intentions. Risk propensity moderated the relationship between behavioral inten- tions and actual usage behavior. As a contribution to the expanding literature, the research extended the application of the UTAUT2 framework to the context of sports fantasy gaming apps. The research also provides valuable insights for researchers and professionals associ- ated with sports fantasy gaming apps and future research directions. 2024 -
Does brand association, brand attachment, and brand identification mediate the relationship between consumers willingness to pay premium prices and social media marketing efforts?
This study investigates the effects of social media marketing efforts (SMME) on smartphone brand identification, attachment, association, and willingness to pay premium prices. A survey of 320 smartphone users who followed official social media handles managed by smartphone companies was conducted for this purpose. PLS-SEM was used to analyse the collected data. The findings demonstrated importance of SMME dimensions. According to the studys findings, the smartphone brands SMMEs had significant impact on brand identification, brand association, and brand attachment. The results revealed that SMMEs had significant impact on willingness to pay the premium price. The findings also show that brand identification, attachment, and association mediated the relationship between SMMEs and willingness to pay a premium price. The findings of this study will be useful in developing social media marketing strategies for smartphones. This study demonstrates the use of social media marketing to promote mobile phones, particularly in emerging markets. Copyright 2024 Inderscience Enterprises Ltd. -
From the homestead to centerstage: A journey of empowerment; [De la granja al centro de escena: Un viaje de empoderamiento]
The Kerala Model of Development has been widely acclaimed for its contribution in generating favourable social indices at par with Scandinavia. The central issue to the development in almost all underdeveloped and developing countries is the empowerment of women constituents. In Kerala, the story of empowerment of women is not just economic, but psychological too. Under Article 243(D) of the Constitution of India, there is a mandate to provide 50% reservation for women in Local Self-Government Institutions (LSGIs). This constitutional amendment is regarded as a path-breaking move to empower women at the grassroots level. This article portrays the impact of government interventions for ensuring the participation of women in decision-making as well as in the power structure in LSGIs. The researcher(s) used multiple case study design and adopted purposive sampling. The data was collected through in-depth interviews and focus group discussions were used for triangulation. The finding of the study shows that how the women are empowered though various government interventions such as Kudumbashree (the name of Keralas Poverty Eradication Mission), Mahatma Gandhi National Rural Employment Guarantee Act (the job guarantee scheme in India), Accredited Social Health Activist Scheme (a scheme of National Rural Health Mission) and Local Self-Government Institutions. 2020, Hipatia Editorial.

Comparative efficiency analysis of RF power amplifiers with fixed bias and envelope tracking bias
RF power amplifier (RF PA) finds its application in almost all the areas of electronics, mobile communication being identified as a major area. The paper performs a comparative efficiency analysis of RF power amplifiers operating with a fixed bias and an envelope tracking bias. Simulations are performed using Keysight advanced design system (ADS) tool. A class a RF PA operating at a 12 dB gain is fixed for the work. 16 QAM LTE signal operating at 5 MHz input frequency, with a peak to average power ratio (PAPR) of 6.0 dB is used as input signal. An envelope simulation at 2.5 GHz is performed on the RF power amplifier. Simulation result shows an improvement of 12% in power added efficiency (PAE) at 6 dB back-off and 6.422% in mean PAE while using envelope tracking power amplifiers, compared to RF PA with fixed supply. Envelope tracking power amplifiers reduced AM/AM distortions also by a factor of 0.248. The results obtained are much better than that obtained using a conventional RF PA with fixed bias. RF PA being the most power dissipative block in a mobile handset, improving its efficiency contributes directly to a great improvement in the battery lifetime of mobile phones. The major challenges faced by envelope tracking PA (ETPA) designers in achieving this efficiency improvement is also delineated in the paper. 2024 Institute of Advanced Engineering and Science.
