Priority Based Routing for Mobile Peer-To-Peer Communications

In a Mobile Peer-to-Peer (MP2P) network, mobile nodes share their resources among one another in a mobile wireless environment. Communication among nodes in MP2P network has become an important area for research due to the significance of its applications. The success of these MP2P applications depends on the number of users in the network, popularity of services offered, quick response and faster access to services. Some services offered could be more popular than others and some peers may contribute more to the network by catering to more requests compared to other peers. In priority based routing mechanism, there is an increase in the priority of a peer with the increase in the number of times it provides services to other peers. The priority of a shared service also increases as the number of requests for that service increases. Also, the mechanism of priority based mobile peer-to-peer routing provides higher priority for traffic destined to high contributing peers and the traffic of popular services, during routing. This would provide high contributing peers quicker response and faster access to services. Hence, this mechanism motivates more users to join the MP2P network and contribute more to the network

Results highlight significant impact of using reflective journal writing on students\u27 understanding of ethics concepts through recorded increase in grades and reduction in fail rates

Corporate plagiarism during remote work – a concern?

Plagiarism is a type of academic misconduct that has plagued the education sector for years. It may be one of the most common forms of academic misconducts that is identified in schools (K-12) and higher education sector. Plagiarism is when someone uses someone else’ intellectual property and passes it off as own work without any acknowledgement or attribution.While the topic is well documented and discussed in the academic world, very little is known about how it plays out in the corporate world (Reyman, 2008), except that some studies have shown that students who have a tendency to engage in academic misconduct in academia also demonstrate propensity for unethical practices in the workplace (Khan, al-Qaimari & Samuel, 2007; Daniel et al., 2009).Preliminary discussions during a virtual summit in a Middle Eastern country involving participants from corporate sectors across the region revealed concerns over employees copying and pasting text, code, images and other property when working on company reports or developing digital products. Particular concern arose over “outsourcing” of certain business functions such as “marketing” and “digital content creation”. Some participants shared how they were pressured to create content for clients within unrealistic timeframes and expected to either copy from the web or simply reuse content previous created for other clients. Concerns were focused on corporate sector, but also included administrative staff at educational institutions such as faculty coordinators, marketing and digital content staff, library and registrars’ staff, student services staff, and so on.Majority of concerns discussed revolved around lack of prior knowledge of concepts such as plagiarism among employees during their education career, or copyright and intellectual property infringements; while for educational institutions, the concern was over lack of focus on need to raise awareness among non-faculty staff, beyond courses and subject content.This presentation proposes to look at plagiarism that takes place in the corporate world and how that has become a new concern in the era of remote work due to the COVID19 pandemic, irrespective of the sector the company is in and how academic world can support corporate sector and better prepare future professionals. &nbsp

UPLBSN: User Profiling in Location-Based Social Networking

Online social networks serve various purposes and help mankind in many ways. The amount of information in social networks is increasing everyday, making it huge data source for its users. All the data available in social networks may not be trustworthy. In this work, we present an intelligent, crowd-powered information collection system that identifies the set of trusted experts topic-wise in Twitter social network. The proposed UPLBSN algorithm presented in this work identifies trusted experts by finding the relationship between content of tweets and the tweet location. The topic(s) of user posts are clustered by extracting the keywords and are stored in the database. Profiled profound users are presented to the business users based on the topic searched by them. The proposed UPLBSN algorithm is evaluated by conducting experiments on Twitter data set to demonstrate its adequacy

Mineral Composition, Total Phenol Content and Antioxidant Activity of a Macrolichen Everniastrum cirrhatum (Fr.) Hale (Parmeliaceae)

In the present study, we investigated for the first time mineral composition, total phenol content and antioxidant activity of a foliose macrolichen Everniastrum cirrhatum (Fr.) Hale (Parmeliaceae) from Bhadra wildlife sanctuary, Karnataka, India. Mineral content of the lichen was estimated by Atomic absorption spectrophotometer after acid digestion. The secondary metabolites were detected by thin layer chromatography (TLC) and phytochemical assays. The lichen material was extracted with methanol in soxhlet apparatus. Total phenol content was estimated by folin ciocalteu method. Antioxidant activity was determined by DPPH, Ferric reducing and metal chelating assays. Among the principal elements, calcium was found in high concentration followed by magnesium, potassium and phosphorus. Among trace elements, iron was detected in high amount followed by zinc, manganese and copper. The DPPH radical scavenging activity was found to be dose dependent with an IC50 of 6.73 μg/mL. In ferric reducing assay, the absorbance increased with the concentration of extract suggesting reducing power. The extract exhibited good metal chelating activity with an IC50 value of 29.28 μg/mL. Total phenol content was 101.2 mg tannic acid equivalents per gram of extract. Phytochemical analysis revealed the presence of alkaloids, saponins, tannins and terpenoids. TLC revealed atranorin, salazinic acid and protolichesterinic acid. The lichen can be consumed as a source of minerals required for the body as appreciable amount of minerals has been detected. The marked antioxidant activity may be attributed to the presence of phenol content in the extract. Further studies on isolation of metabolites and their bioactivities are under investigation

Epoxidation of styrene over MgO-rice derived carbon composite catalyst prepared by <em>in situ</em> transformation technique

1106-1111With a view to develop eco-friendly and metal-free catalysts, herein we report MgO-rice derived carbon composite for epoxidation of styrene to styrene epoxide. MgO-C catalysts prepared via in situ transformation technique are characterized by powder XRD, BET-surface area, Raman spectroscopy, CO2-TPD, CHNS analysis and TGA techniques. Under optimized reaction conditions, MgO-C0.5 catalyst efficiently catalyzed the reaction with 84% conversion of styrene yielding 82% selectivity to styrene epoxide. The characterization results suggest that the catalytic activity is attributed to the presence of well dispersed accessible basic sites obtained through in situ dispersion of MgO over rice derived carbon. MgO-C0.5 catalyst is recyclable up to four cycles without significant loss in the activity and selectivity

Real-World Effectiveness of COVID-19 Vaccine and Identification of SARS-CoV-2 Variants among People Living with HIV on Highly Active Antiretroviral Therapy in Central Kerala of India—An Ambi-Directional Cohort Study

Background: Vaccine effectiveness for first-generation coronavirus disease (COVID-19) vaccines among People Living with HIV (PLHIV) in India remains unexplored. This study entails the estimation of the real-world effectiveness of COVID-19 vaccines (AZD1222/Covishield, BBV152/Covaxin) among PLHIV and the identification of variants of SARS-CoV-2 among those infected with COVID-19. Methods: An ambi-directional cohort study was conducted among 925 PLHIV above 18 years of age in two districts of central Kerala, India, from February 2022 to March 2023. Selected PLHIV were recruited as Participant Liaison Officers (PLOs) for the follow-up on the study participants. At enrolment, basic details, baseline CD4 count, and a Nasopharyngeal (NP) swab for RT-PCR were collected. In the follow-up phase, NP swabs were collected from subjects with COVID-19 symptoms. Positive subjects had a CD4 count and genomic sequencing performed. Results: The mean age of the participants was 46.93 ± 11.00 years. The majority, 819 (93.6%), of participants had received at least one dose of any vaccine, while 56 (6.4%) were unvaccinated. A total of 649 (79.24%) participants were vaccinated with Covishield and 169 (20.63%) with Covaxin. In the vaccinated group, 158 (19.3%) reported COVID-19 infection. Vaccine Effectiveness (VE) for one dose of any vaccine was 43.2% (95% CI: 11.8–64.5), p = 0.015. The effectiveness of full vaccination with Covishied was 63.8% (95% CI: 39.3–79.2), p 350 had greater protection from COVID-19, at 53.4% (95% CI: 19.6–75.3) p = 0.004. The incident cases were sub-variants of Omicron (BA.2, BA.2.38, BA.2.10). Conclusions: Full vaccination with Covishield and Covaxin was effective against COVID-19 infection among PLHIV on treatment; albeit, that of Covaxin was higher. A gap of 4 to 6 weeks between the two doses of COVID-19 vaccine was found to have higher VE among PLHIV
