Solving Fuzzy Differential Equations using R-K (Runge-Kutta) Method

R. Keerthika — 2024-04-17

In a wide variety of technical specialties as well as in the field of medical, (fuzzy differential equations) FDEs models being used. Chang S.L. and Zadeh L.A. developed the term “fuzzy derivative.” After that, Dubosis, D., and Prade applied the extension principle in their strategy. Kandel A. and Byatt W.J. coined the phrase “fuzzy differential equation” in 1987. This study applies the Hukuhara derivative of the fuzzy process to the R-K Method of order 5 to solve fuzzy first- and second-order ODEs. This approach has been demonstrated by resolving a fuzzy Cauchy problem, followed by the numerical elucidation of FDEs using the order of five of R-K method.

Green Synthesis and Characterization of Zinc Oxide Nanoparticles using Plectranthus amboinicus Leaf Extract

P. Srisathya — 2024-04-17

Nanoscience and nanotechnology have been established recently a new interdisciplinary science and now a day it is one of the most attractive research area in modern material science. The aim of this work was to investigate the photo catalytic property of Zinc oxide nano particles by using Plectranthus ambionicus leaf extract at various concentration. The average crystalline size of the prepared ZnO nanoparticles was calculated in XRD analysis. The UV-visible absorption spectrum indicates the band gap of green synthesis ZnO nanoparticles. The synthesized zinc oxide nanoparticles were subjected to Fourier Transform Infrared spectroscopy (FTIR) analysis to detect the various functional groups associated with the prepared nano particles. The Scanning Electron Microscopy (SEM) analysis to measure the morphological structure of synthesized ZnO Nano particles. Moreover, the green synthesized Zno nanoparticles showed a superior photo catalytic performance than chemically synthesized Zno particles.

Green Synthesis of Calcium Oxide Nanoparticles using Leaves Aqueous Extract of Cymbopogon citratus and Evaluation of their Antibacterial Activities

Calcium Oxide (CaO) has an individual catalystic and optical properties which can be synthesizedsuccessfully by green synthesis. The present study is to synthesize CaO nanoparticles from the leaf extracts of Cymbopogon citratus, commonly known as lemon grass. This method makes use of contamination free chemicals and promote the use of non-toxic substances, such as water and plant extract. The observation on Morphology of the particles of lemon grass powder was studied through Scanning Electron Microscope (SEM). The X-ray diffraction studies revealed the Polycrystalline nature of CaO nanoparticles. The optical and functional studies of the CaO nanoparticles was analyzed using UV- Vis, FTIR studies. The photocatalytic and Anti-Bacterial activity of calcium oxide nanoparticles is also analyzed. The composition of elements was studied by using EDAX.

Impact of Stress Lightening Dietary Education on Knowledge and Stress Eating Attitude among Night Shift Working Nurses

D. Sneha — 2024-04-17

Objective: To assess the effectiveness of stress lightening dietary education on knowledge and stress eating attitude among night shift working nurses at selected Hospitals in Thiruvarur district. Methodology: Quantitative approach. A quasi-experimental design was adopted to assess the effectiveness of stress lightening dietary education on knowledge and stress eating attitude among night shift working nurses (120 samples) at Thiruvarur Government Medical College, Kamakshi Hospital in Thiruvarur district. Purposive sampling technique was utilized to choose the samples. StressLightening Dietary Education was administered, and the level of knowledge and stress eating attitude was assessed by using a self-structured knowledge questionnaire and a modified Salzburg stress eating attitude scale and contrasted with the pre-test and post-test levels of knowledge and stress eating attitude among night shift working nurses. Results: The research findings revealed that the post-test mean knowledge score of night shift nurses was 8.54 with an SD of 0.78, and their post-test mean stress eating attitude score was 32.12 with an SD of 3.67. The calculated paired “t” value (56.358 and 23.819) for knowledge and stress eating attitude shows that there was a high statistical difference at p<0.001. Conclusion: The results revealed that stress-lightening dietary education was an effective intervention tool in enhancing the knowledge and stress-eating attitude regarding stress-lightening dietary practices among night shift nurses.

A Mixed Method Approach to Explore and to Assess the Effectiveness of Nutrition Education Regarding Dietary Taboos on Knowledge and Attitude Among Postnatal Mothers at Selected Rural Areas in Thanjavur District

K. Kayalvizhi — 2024-04-17

Aim & objective: To assess the effectiveness of nutrition education regarding dietary taboos on knowledge and attitude among postnatal mothers at selected rural areas in Thanjavur district. Material and Method: A mixed method approach carried in two phases. Initially started with quantitative using purposive sampling technique with 65 postnatal mothers to assess the effectiveness of nutrition education on knowledge and attitude regarding dietary taboos followed by which the qualitative phase using judgemental sampling among 5 postnatal mothers was explored about their dietary taboos. The assessment of demographic variables and knowledge, dietary pattern with food frequency and 24 hours dietary recall with self structured questionnaire and attitude regarding dietary taboos among Post-natal mothers with 4 point likert attitude scale. Results: Results of the study revealed that post-natal mothers’ post-test mean knowledge score was 9.03 with S.D. 0.92, and their post-test mean attitude score was 34.92 with S.D 2.88. According to the calculated ‘t’ values t = 37.762 for knowledge and t = 43.019 for attitude, there was a statistically significant difference in mean scores among postnatal mothers at p = 0.005.The qualitative study revealed that the postnatal mothers was identified to followed certain dietary restrictions few of which was considered to be dietary taboos on scientific ground like pineapple, jackfruit, papaya, red guava and drumstick leaves and others . Conclusion: The study enhanced postnatal mothers’ knowledge and attitudes about dietary taboos. The participants were acquainted about the various factors that cause them to follow dietary taboos.

Social Media Networking by Students in Search of Information: Special Reference on Bishop Heber College

C. Anneruth — 2024-04-17

This study deals with social media networking by students in search of information: special reference on Bishop Heber College. Students are turning to the internet more and more for social interaction. In this study, we looked at how often students used social media sites, as well as how much time they spent on social networks. We looked at people who used Face book, Twitter, and LinkedIn, as well as a few other social media sites. We wanted to figure out how important different activities on social media sites were. We sent out 190 questionnaires and got back 170 valid ones with an 85% response rate. The collected data was analyzed with the SPSS. Illustrates the prevalence of social media use among male categories (102) compared to female categories (68). The majority of social media users come from urban areas (111). Facebook (60) is the most commonly used social media network among students at Bishop Heber College. The opinion of the social media networks among the students and 60 students out of 170 expressed their opinion as social media networks are excellent. This research paper clearly deals with the social media networking sites.
