Background: Chronic wounds continue to pose a serious healthcare challenge, and while Siddha medicine traditionally recommends Mezhugu Kalimbu for wound care, scientific validation of its healing properties is scarce. This study was designed to evaluate the wound-healing potential of Mezhugu Kalimbu and compare its efficacy with its individual components (Mezhugu and coconut oil), standard treatment (povidone iodine), and untreated control. Materials and Methods: Thirty Wistar albino rats were divided into five groups: untreated, standard (povidone iodine), coconut oil, Mezhugu, and Mezhugu Kalimbu. Full-thickness excision wounds were created, and topical applications were administered every 48 hours. Wound contraction rate and unit healing time were recorded and analyzed using SPSS. Results and Discussion: Mezhugu Kalimbu group showed significantly greater wound contraction compared to other groups (p < 0.05). Complete wound closure was achieved by Day 12, with a 100% mean contraction rate and the shortest mean healing time (8.32 days). The superior healing effect is attributed to the synergistic actions of Mezhugu with moistureretentive and antibacterial properties and coconut oil, which contributes anti-inflammatory and collagen-promoting effects. Conclusion: Mezhugu Kalimbu demonstrated significantly enhanced wound-healing activity compared to its individual components and the standard treatment, highlighting its potential as an effective, accessible, and affordable wound care formulation within Siddha medicine.

LinkedIn serves as a platform for professional networking, tailored for career-focused interactions. This research explored the usage patterns, benefits, and barriers of LinkedIn among undergraduate students at Trincomalee Campus, Eastern University, Sri Lanka, with an emphasis on how they use the platform to boost their career opportunities and professional development. The study primarily utilized a survey to gather data, involving 120 undergraduate students from the Faculty of Communication and Business Studies and the Faculty of Applied Science at Trincomalee Campus. The theoretical framework for the study was based on the Technology Acceptance Model (TAM). The results indicated that most undergraduate students perceive LinkedIn as a crucial tool for obtaining internships and then entering the workforce once they graduated. They utilize LinkedIn to network with industry professionals and companies and to join groups that align with their career interests. Furthermore, the study identified barriers faced by undergraduate students, such as difficulties in creating a professional profile and maintaining the regular engagement. These findings imply that universities should incorporate LinkedIn training into their career services to better equip undergraduate students for the competitive job market. Improving digital literacy and offering guidance on effective LinkedIn strategies could greatly enhance students’ employability and professional growth.

Visible light communication (VLC) is a revolutionary wireless communication paradigm that has the potential to revolutionize the industry. VLC transmits information by modifying the visible light spectrum (400-700 nm) that is utilized for lighting. VLC's ability to enable high-speed data connection with enhanced energy economy and communication security/privacy has been demonstrated via analytical and experimental studies. VLC is currently in its early stages of development. There have been several review papers and books written on this subject, with the majority of them focusing on physical layer research. This paper provides a VLC system perspective as well as possible VLC applications and integration problems.

Abstract Introduction: Type 2 diabetes mellitus (T2DM) known as Mathumegam is a significant health concern in the twenty-first century. Despite great advances in contemporary science, there is a lack of moderately safe and effective drugs for treatment. The purpose of this study was to evaluate the efficacy of a poly herbal traditional decoction containing 10 herbs such as Senna auriculata (root & bark), Cissampelos pareira (root), Ficus racemosa (bark), Terminalia arjuna (bark), Acacia arabica (bark), Syzygium cumini (bark), Curcuma longa (rhizome), Terminalia chebula (fruit pulp), Phyllanthus emblica (dry fruit), and Terminalia bellirica (fruit pulp) in the management of T2DM. Materials and Methods: It was a double-blind, randomized controlled trial involving 100 T2DM patients who were not well managed by diet or exercise. For a period of 12 weeks, 50 patients in group A were administered 5g of the test medication mixed with 100ml (one tumbler) of hot water for 10 to 15 min, as well as standard Western therapy. Group B patients (n=50) received a placebo in addition to normal Western therapy. The main focus of the study was to achieve a 3-month decrease in glycosylated hemoglobin (HbA1c) levels from the starting point, with additional objectives including lowering fasting blood glucose (FBG) levels and observing changes in diabetic symptoms. Results: At the end of the trial, mean fasting blood glucose levels decreased to 119.04 ± 11.52 and 176.90 ± 13.91 mg/dL in the test and control groups, respectively. Group A showed a more significant decrease in mean fasting blood glucose levels compared to group B. This indicates that the daily use of poly herbal traditional decoction along with standard allopathic medical therapy for 3 months led to notable reductions in FBG levels. Similarly, group A showed greater improvement in the measured signs and symptoms of diabetes, such as polydipsia, polyuria, polyphagia, weariness, and burning sensation in the hands and feet compared to group B throughout the trial. At baseline, the mean HbA1c (%) in group A and group B was 7.47 ± 0.70 and 7.39 ± 0.66, respectively. After 12 weeks of investigation, the levels of glycated hemoglobin were lowered to 5.03 ± 0.53 and 6.79 ± 0.51 respectively. There were no adverse events reported during the trial period. Conclusion: This study found that the experimental medication was beneficial in T2DM, radically lowering FBG and HbA1c levels in diabetic individuals after 12 weeks of treatment.

The second-order (v2) and third-order (v3) Fourier coefficients describing the azimuthal anisotropy of prompt and nonprompt (from b-hadron decays) J/ψ, as well as prompt ψ(2S) mesons are measured in lead-lead collisions at a center-of-mass energy per nucleon pair of sNN\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$ \\sqrt{s_{\ extrm{NN}}} $$\\end{document} = 5.02 TeV. The analysis uses a data set corresponding to an integrated luminosity of 1.61 nb−1 recorded with the CMS detector. The J/ψ and ψ(2S) mesons are reconstructed using their dimuon decay channel. The v2 and v3 coefficients are extracted using the scalar product method and studied as functions of meson transverse momentum and collision centrality. The measured v2 values for prompt J/ψ mesons are found to be larger than those for nonprompt J/ψ mesons. The prompt J/ψ v2 values at high pT are found to be underpredicted by a model incorporating only parton energy loss effects in a quark-gluon plasma medium. Prompt and nonprompt J/ψ meson v3 and prompt ψ(2S) v2 and v3 values are also reported for the first time, providing new information about heavy quark interactions in the hot and dense medium created in heavy ion collisions.

A search for long-lived particles decaying in the outer regions of the CMS silicon tracker or in the calorimeters is presented. The search is based on a data sample of proton-proton collisions at sqrt{s} = 13 TeV recorded with the CMS detector at the LHC in 2016–2018, corresponding to an integrated luminosity of 138 fb−1. A novel technique, using nearly trackless and out-of-time jet information combined in a deep neural network discriminator, is employed to identify decays of long-lived particles. The results are interpreted in a simplified model of chargino-neutralino production, where the neutralino is the next-to-lightest supersymmetric particle, is long-lived, and decays to a gravitino and either a Higgs or Z boson. This search is most sensitive to neutralino proper decay lengths of approximately 0.5 m, for which masses up to 1.18 TeV are excluded at 95% confidence level. The current search is the best result to date in the mass range from the kinematic limit imposed by the Higgs boson mass up to 1.8 TeV.

The path-length dependent parton energy loss within the dense partonic medium created in lead-lead collisions at a nucleon-nucleon center-of-mass energy of sqrt{s_{textrm{NN}}} = 5.02 TeV is studied by determining the azimuthal anisotropies for dijets with high transverse momentum. The data were collected by the CMS experiment in 2018 and correspond to an integrated luminosity of 1.69 nb−1. For events containing back-to-back jets, correlations in relative azimuthal angle and pseudorapidity (η) between jets and hadrons, and between two hadrons, are constructed. The anisotropies are expressed as the Fourier expansion coefficients vn, n = 2–4 of these azimuthal distributions. The dijet vn values are extracted from long-range (1.5 < |∆η| < 2.5) components of these correlations, which suppresses the background contributions from jet fragmentation processes. Positive dijet v2 values are observed which increase from central to more peripheral events, while the v3 and v4 values are consistent with zero within experimental uncertainties.

The aim of this research is to analyze the novel, Things Fall Apart as a liminal Identity: Thematic approach of Identity Crisis from the perspective of Postcolonial Literature. The study analyzes the plot development and the thematic aspects of the novel on one level. On the other level the paper analyzes how the facts related to the colonial aspects of Africa and the impact of colonialism are embedded in this fiction. Therefore, it is a comparative study of Post-colonialism and Post-Colonial Literature. A brief introduction to Postcolonial literature is given at the outset. The indication of the word ‘post-colonialism’ along with the origin and development of the postcolonial theories and studies are critically examined. The research evaluates the thematic aspect of postcolonial literature, identity crisis with special reference to liminal identity. It also critically analyses the various representative authors like Rushdie, Achebe, Ondantje, Fanon, Derek Walcott, and J. M. Coetzee in addition to some female writers like Jamaica Kancaid, Isabelle Illende and Eavan Bolland. Furthermore, it also briefly examines the political history of colonization and the impact of colonialism on the literature produced during post-colonial period. The research introduces Chinua Achebe, the author of Things Fall Apart, from the point of his personal and historical background in order to compare the content and the context of his writing. Thus, the study reveals that the novel, Things Fall Apart, is a revelation of Identity Crisis.
