Damping of composite material structures with bolted joints

In the present work, the damping in composite structures with bolted joint has been extensively studied by the use of finite element analysis model. The various operations viz. modal, harmonic response and transient dynamic analyses are stimulated to find out different results in ANSYS and calculations were done as per the results from ANSYS to find further results. The parameters related to damping in composite bolted joints are found. It has been inferred from the paper that damping in composite bolted joint is very high. Rayleigh’s damping constants and loss factor in the structure has also been calculated. A detailed mathematical and analytical model has been presented for understanding damping better. This topic of research is beneficial for various upcoming and ongoing products in the market

An evaluation of efficacy of Lichtenstein mesh hernioplasty in emergency settings: a study in tertiary care hospital in Odisha

Background: Despite the high incidence, the technical aspects of hernia repair continue to evolve making it the most common operations performed by general surgeons. Lichtenstein mesh hernioplasty repairs all hernias without distortion of the normal anatomy and with no suture line tension. This study was performed to evaluate the outcomes of Lichtenstein mesh herinioplasty in emergency inguinal hernia patients.Methods: A 84 patients were operated for complicated (obstructed irreducible) inguinal hernia. A follow-up period of 6 months using the Quantitative and Qualitative Measurement Instrument for evaluation of Lichtenstein hernioplasty outcomes was completed for 44 emergency patients.Results: The age incidence of the hernia patients in the study group was 40% (25-35 years) followed by 24% (15-25 years). The anatomical position of the hernia in the study group was to the right having a dominant percentage of 72% followed by left (24%) with none in bilateral. Early postoperative complications in mesh repair (Lichtenstein hernioplasty) comprising of factors like wound infection (10%), hematoma (5%), seroma (10%) was significantly lower compared to tissue repair with wound infection (20%), hematoma (5%) and seroma (25%). Further mesh rejection in Lichtenstein hernioplasty was 0% for the study population. Similarly, late postoperative complications in Lichtenstein hernioplasty comprising of factors like wound dehiscence (4%), neuralgia (27%) was significantly lower compared to tissue repair with wound dehiscence (27%), neuralgia (41%).Conclusions: The study revealed that the use of polypropylene prosthesis in the emergency setting (obstructed hernia) is safe and outcomes are satisfactory

Fashioning readers: canon, criticism and pedagogy in the emergence of modern Oriya literature

Through a brief history of a widely published canon debate in nineteenth century Orissa, this article describes how anxieties about the quality of ‘traditional’ Oriya literature served as a site for imagining a cohesive Oriya public who would become the consumers and beneficiaries of a new, modernized Oriya-language canon. A public controversy about the status of Oriya literature was initiated in the 1890s with the publication of a serialized critique of the works of Upendra Bhanja, a very popular pre-colonial Oriya poet. The critic argued that Bhanja’s writing was not true poetry, that it did not speak to the contemporary era, and that it featured embarrassingly detailed discussions of obscene material. By unpacking the terms of this criticism and Oriya responses to it, I reveal how at the heart of these discussions were concerns about community building that presupposed a new kind of readership of literature in the Oriya language. Ultimately, this article offers a longer, regional history to the emerging concern of post-colonial scholarship with relationships between publication histories, readerships, and broader ideas of community – local, Indian, and global

Post COVID sequelae among COVID-19 survivors: insights from the Indian National Clinical Registry for COVID-19

Introduction The effects of COVID-19 infection persist beyond the active phase. Comprehensive description and analysis of the post COVID sequelae in various population groups are critical to minimise the long-term morbidity and mortality associated with COVID-19. This analysis was conducted with an objective to estimate the frequency of post COVID sequelae and subsequently, design a framework for holistic management of post COVID morbidities.Methods Follow-up data collected as part of a registry-based observational study in 31 hospitals across India since September 2020–October 2022 were used for analysis. All consenting hospitalised patients with COVID-19 are telephonically followed up for up to 1 year post-discharge, using a prestructured form focused on symptom reporting.Results Dyspnoea, fatigue and mental health issues were reported among 18.6%, 10.5% and 9.3% of the 8042 participants at first follow-up of 30–60 days post-discharge, respectively, which reduced to 11.9%, 6.6% and 9%, respectively, at 1-year follow-up in 2192 participants. Patients who died within 90 days post-discharge were significantly older (adjusted OR (aOR): 1.02, 95% CI: 1.01, 1.03), with at least one comorbidity (aOR: 1.76, 95% CI: 1.31, 2.35), and a higher proportion had required intensive care unit admission during the initial hospitalisation due to COVID-19 (aOR: 1.49, 95% CI: 1.08, 2.06) and were discharged at WHO ordinal scale 6–7 (aOR: 49.13 95% CI: 25.43, 94.92). Anti-SARS-CoV-2 vaccination (at least one dose) was protective against such post-discharge mortality (aOR: 0.19, 95% CI: 0.01, 0.03).Conclusion Hospitalised patients with COVID-19 experience a variety of long-term sequelae after discharge from hospitals which persists although in reduced proportions until 12 months post-discharge. Developing a holistic management framework with engagement of care outreach workers as well as teleconsultation is a way forward in effective management of post COVID morbidities as well as reducing mortality

Estimation of tuberculosis incidence at subnational level using three methods to monitor progress towards ending TB in India, 2015–2020

Objectives We verified subnational (state/union territory (UT)/district) claims of achievements in reducing tuberculosis (TB) incidence in 2020 compared with 2015, in India.Design A community-based survey, analysis of programme data and anti-TB drug sales and utilisation data.Setting National TB Elimination Program and private TB treatment settings in 73 districts that had filed a claim to the Central TB Division of India for progress towards TB-free status.Participants Each district was divided into survey units (SU) and one village/ward was randomly selected from each SU. All household members in the selected village were interviewed. Sputum from participants with a history of anti-TB therapy (ATT), those currently experiencing chest symptoms or on ATT were tested using Xpert/Rif/TrueNat. The survey continued until 30 Mycobacterium tuberculosis cases were identified in a district.Outcome measures We calculated a direct estimate of TB incidence based on incident cases identified in the survey. We calculated an under-reporting factor by matching these cases within the TB notification system. The TB notification adjusted for this factor was the estimate by the indirect method. We also calculated TB incidence from drug sale data in the private sector and drug utilisation data in the public sector. We compared the three estimates of TB incidence in 2020 with TB incidence in 2015.Results The estimated direct incidence ranged from 19 (Purba Medinipur, West Bengal) to 1457 (Jaintia Hills, Meghalaya) per 100 000 population. Indirect estimates of incidence ranged between 19 (Diu, Dadra and Nagar Haveli) and 788 (Dumka, Jharkhand) per 100 000 population. The incidence using drug sale data ranged from 19 per 100 000 population in Diu, Dadra and Nagar Haveli to 651 per 100 000 population in Centenary, Maharashtra.Conclusion TB incidence in 1 state, 2 UTs and 35 districts had declined by at least 20% since 2015. Two districts in India were declared TB free in 2020
