An Overview on the applications of different polymers in capture of Carbon dioxide from atmosphere

Carbon dioxide discharges are increasing at a quick speed in the environment. CO2 is a significant ozone-depleting gas, and its exhausts induce overall temperature variations, which bring about ecological adjustment. As the world accelerates in its battle against environmental modification, climate can differ from one location to the next. Still, when we talk about climate modification, we’re discussing a variant in the usual weather patterns of an area. This could be because of a change in the Planet’s average temperature or maybe a modification in the number of rainstorms and snow. Human beings are progressively affecting the environment as well as the Planet. This includes many greenhouse gases contrasted to those discovered naturally in the atmosphere. Environment change is specified as an adjustment in the average conditions of an area, such as temperature level and rains, over an extended period of time. When we see where climate adjustment influences, unfortunately, it is throughout the world. This presentation will most likely go over various case studies. This evaluation focuses on carbon capture issues with the very best probability of limiting CO2 exhausts to the atmosphere from big point sources. According to a brand-new study that combines the most up-to-date research studies from the United Nations, the buildup of unmatched quantities of greenhouse gases in the environment devotes the world to disastrous future warming. Tape levels of greenhouse gases in the environment dedicate the Earth to disastrous future warming

Pattern and visual outcomes of ocular fire-cracker injuries during Diwali festival in a tertiary Care Hospital in North India

Background: The firecrackers are used widely during Diwali. Eyeball is one of the most commonly injured organ in firecracker injuries. The fire-crackers can cause irreparable damage to ocular structures, leading to blindness. This study was conceptualized to study the pattern of injuries resulting from fire-cracker use and their visual outcomes, in order to generate evidence for managing these injuries more effectively. Material and Methods: This longitudinal, descriptive study was carried out over a period of one week during Diwali festival in 2019, in a tertiary care teaching hospital in North India in 21 patients who presented to hospital with ocular injuries caused by firecrackers. Visual acuity was recorded and complete slit lamp examination, non-contact tonometery, and gonioscopy was done. Ultrasound B-scan and X-ray were also done, when required. Results: The mean age in our study was 18.42±11.88 years with age range of 7-57 years. There were 20 males and 1 female in the study. Most of the injuries were caused by bombs and sparkles. Most of the patients (50%) had visual acuity in range of 6/6-6/24 at the time of presentation. Conjunctival surface was involved in all the patients, followed by lids and cilia (59.09%). One patient had corneal perforation with uveal tissue proplase.Six patients had vitreous haemorrahge and seven patients had hyphema. Final visual outcome was favorable with 63.64% patients achieving vision of 6/6- 6/24 at the end of six weeks. Conclusion: Severe injuries can lead to permanent loss of vision or decreased vision from squealae of wound healing such as astigmatism. Hence, stricter implementation of existing laws and regulations, public education and awareness is needed to prevent avoidable blindness resulting from use of fire crackers

Demographic and Clinical Profile of Presbyopia in a Tertiary Care Centre

Introduction: Presbyopia is an age related loss of accommodative amplitude leading to difficulty with near vision and near work. The onset of presbyopia occurs around 40-45 years of age in most individuals. It may lead to difficultly in performing various tasks of daily routine Keeping in view the high prevalence of uncorrected presbyopia, this study was conceptualized to study the demographic profile of presbyopia, in order to create awareness among the general population, which would help us in managing this condition, more effectively. Material and methods: This observational, cross-sectional study was carried out among 500 patients who presented to out-patient clinics. Detailed medical history and ocular examination was done. Distance visual acuity was recorded with Snellen chart and near vision with Jagger’s chart. All data was entered in Microsoft excel and subsequently analyzed with OpenEpi software version 3. Results: The prevalence of presbyopia was 22.8% with mean age of 52.17±9.52 years and age range of 32- 60 years. Females were more commonly affected (75.44%) as compared to males. Most of the patients presented with difficulty in near vision (69.29%) and were emmetropic for distance vision (63.15%). Maximum patients were literate (80.7%). Homemakers and office-worker seek medical advice earlier as compared to others. Conclusions: Females were more commonly affected and had younger onset of presbyopia as comapared to males. Hypermetropia was more commonly associated with presbyopia as compared to myopia
