Assessment of Mass-Transfer Effects and Elementary Reaction Scheme for Catalytic Reactors

Catalytic combustion is carried out in a tubular reactor of radius in the order of millimeters and a length of around 10 centimeters in presence of catalysts Rhodium and Platinum. For mass transfer coe�cient calculation in the modeling of mass transfer between the bulk of the uid to the surface, correlations developed by Tronconi and Forzatti(1992) are used. The results shows that the assump- tion stating both the bulk concentration and concentration at the surface are same, deviates from the actual scenario. The combustion is actually slow than what PFR predicts when we observed the mass transfer limited catalytic combustion. A discrepancy is observed with the mechanism of methane partial combustion in the presence of Rhodium catalyst in terms of the concentrations of CO2 and H2O mole fractions, the mechanism gives more CO2 and H2O than the equilibrium composition

Advances in Solid Mechanics and Composites

Applied mechanics is a scientific discipline that focuses on the study of various laws of mechanics and their application in solving engineering problems. The Indian Society for Applied Mechanics (ISAM) organizes conferences focused on various areas of applied mechanics, encompassing solid mechanics, fluid mechanics, and biomechanics. The fifth Indian Conference on Applied Mechanics (INCAM-2022) was jointly organized by the Department of Mechanical Engineering, National Institute of Technology (NIT) Jamshedpur, and ISAM during November 11-13, 2022 at Jamshedpur in India. It provided a technical platform for researchers and academicians to present their research work and discuss the broad field of applied mechanics........

Towards Optimized Management of Bullous Myringitis: A 5-Year Cohort Study Evaluating Treatment Efficacies, Surgical Risks, and Topical Interventions in Contemporary Practice

oai:ejmhr.com:article/1Bullous Myringitis (BM) is a pathological condition characterised by the formation of painful blisters on the tympanic membrane, leading to challenges in its management. The present study investigated the effectiveness of BM treatment, the potential risks associated with surgical interventions, and the efficacy of topical therapy. The study consisted of a retrospective cohort analysis spanning a period of five years, involving a total of 50 patients diagnosed with Bullous Myringitis. The study encompassed an examination of various aspects, including demographics, symptoms, treatments, and outcomes. The efficacy of topical treatments was evaluated through a randomised controlled trial (RCT). The application of linear regression was employed in order to ascertain the predictors of treatment outcomes. The present study investigated the participants' quality of life and the occurrence of complications. The most commonly reported complaint, ear pain, demonstrated the greatest efficacy when treated with topical medication. The randomised controlled trial (RCT) demonstrated that the implementation of topical treatment resulted in a notable amelioration of symptoms and an increase in patient satisfaction. The treatment modality was found to be a significant predictor of positive outcomes, while no significant associations were observed between age and gender and treatment outcomes. The application of topical therapy resulted in a decrease in the occurrence of granular myringitis and a reduction in sensorineural hearing loss. The patients indicated an enhancement in their quality of life subsequent to the intervention. Personalised therapeutic strategies, surgical prudence, and topical therapies play a crucial role in the management of BM. This study presents a comprehensive framework for the implementation of evidence-based procedures related to bowel movements. In order to validate these findings, it is recommended that comprehensive, prospective studies be conducted on a large scale

A Prospective Observational study to Assess the Post-Surgical Outcomes following Cataract Surgery in Patients with Lens Induced Glaucoma

BACKGROUND: Glaucoma is the leading cause of irreversible blindness worldwide with an estimated 60.5 million people affected in 2010 and 12 million people are estimated to be blind due to this disease. India is home to 12 million people with glaucoma and 1.5 million are blind due to it, as per the major prevalence studies in India in the recent past. AIM OF THE STUDY: The main aim of this study was to find out whether a good post-operative visual outcome and Intra Ocular Pressure (IOP) control in patients with Lens Induced Glaucoma (LIG) is obtained using appropriate early medical and surgical management. METHODOLGY: A prospective observational study was carried out for 101 patients who attended Glaucoma clinic at Aravind Eye Hospital, Madurai between January 2018 – June 2018. Ethical approval was obtained from the Institutional Ethical Committee and the IEC no for the study is IEC201800254 Patients diagnosed with LIG were included for the study and those with secondary glaucoma were excluded. With a Confidence Interval (CI) of 95% and statistical significance estimated to be p < 0.05 the statistical analysis was done using STATA (11.1), TEXAS, USA, Software. RESULT: The mean age among 101 patients who were recruited for the study was 94.36 with SD ±9.20. 50.5% of the study subjects were male. With a CI of 95% and statistical significance of (P<0.05) the results were analysed. 35.6% of the patients were diagnosed with LIG in the age group between 61 – 70 years. 20.8% of the patients presented with the acute symptoms after 2 weeks whereas 52.5% presented within 1 week. The right eye was affected in 56.4% of the study participant. Phacolytic Glaucoma (54.5%) was the major incidence of LIG compared to the other group of glaucoma. When comparing the incidence of LIG with gender it is found that both male and female had equal chance of getting infected by the disease and 63.6% of female were affected by Phacomorphic glaucoma and 60.0% male were affected by Phacolytic glaucoma. Hypermature cataract (54.5%) was found to be the highest cause of LIG. The result concluded that there is a decrease in IOP with increase in the visual outcome when the patient was treated early and presented within one week of acute symptoms. CONCLUSION: The result from this study concludes that the visual outcome will be maximized with a decrease in IOP if the patients present with the symptoms early. Despite technological advances in the medical field lack of awareness among the people, barriers to access the service and a high level negligence in certain rural community is still a bottleneck today

A study on biochemical parameters in patients with organophosphorus poisoning

BACKGROUND: The emergency medicine department of Coimbatore Medical College receives 2-3 cases of Organophosphorus compound poisoning on a daily basis. The purpose of this study is to develop an improved scoring system for the risk stratification of Organophosphorus compound poisoning. AIM OF THE STUDY: The study focuses on clinical features and biochemical parameters in patients admitted with acute organophosphorus poisoning and their prognostic significance. MATERIALS & METHODS: The study was conducted at Coimbatore Medical College Hospital for a period of 1 year in patients admitted with acute organophosphorus poisoning in medicine emergency department. On admission, blood samples were sent for biochemical analysis. Based on the clinical presentation at admission, patients were grouped into mild moderate and severe poisoning according to the POP scoring, and the need for ventilator support was noted. RESULTS: The intention of poisoning was found to be suicidal in almost 85 % of the cases admitted and 10% of poisoning was found to be accidental. The most common compound used for poisoning was dichlorfos closely followed by dimethoate and malathion. In our study 69 % cases were graded to have mild poisoning, 27% as moderate and only 4% as severe poisoning. Need for ventilatory support within 24 hours of admission was almost 100% in severe poisoning whereas it was only about 50% in moderate poisoning and less than 10% in mild poisoning. In patients with very low cholinesterase levels at the time of admission, the clinical recovery was much delayed and all cases required ventilator support. The dose of atropine needed in the treatment of opc poisoning also has significant negative correlation with serum acetylcholinesterase levels. CONCLUSION: Most of the biochemical parameters mentioned above show an early elevation in severe OP poisoning; which, when tested, can be used as an early indicator of severity
