In this article we compute the number of fuzzy bitopological space with having two open sets, three open sets, four open sets and five open sets. Also, we have given some results on computation of number of fuzzy bitopological space.
Background:\nThe pandemics of Coronavirus disease 2019 (COVID-19) has still several unknown aspects in the medical centers. The exact route of spreading, the best method for diagnosis, its impact on the patients before and after the surgery, the involvement of hospital staff, and the rate of morbidity and mortality are among the unknown factors that make confronting this virus very complex. \nObjective:\nRo report our trend in COVID-19 as well as experience in surgery in pandemic of COVID-19\nDesign:\nRetrospective description\nSettings:\nAcademic tertiary general medical center\nPatients and Methods:\nIn this comparative cross-sectional study, all consecutive patients undergoing an emergency minor or major surgical procedure between 17th February to 17th May2020, and patients at the same period in 2019 were enrolled and reviewed.\nMain outcome measure:\nCompare mortality at pandemic and no pandemic time\nSample size:\n251 \nResults:\nOne-hundred and forty-seven patients underwent emergency surgical procedures in 2020 (Group A) while the corresponding value was one-hundred and four patients in 2019 (Group B).\nThe male consisted 102 (69.4%) in group A and 85 (81.7%) in-group B. (P= 0.027). the average age of the patients was (46.0 ± 21.4) years in group A and (40.9 ± 17.7) years in-group B.\nConclusion:\nWe found that emergency surgery mortality rates in two groups, group A (pandemic of COVID-19) had significantly higher mortality rate compared with group B (no pandemic COVID-19)\nLimitation:\nSingle center, retrospective and it was not a trail study\nConflict of interest:\nNone\nFunding:\nThis research is not funded by any agency or organization\nEthics Approval Statement:\nThis article does not contain any studies with human participants or animals performed by any authors. For this type of study formal consent is not required
On January 20th, 2020, the first COVID-19 case in Korea was confirmed. The Korean government handled the situation by early identification, early quarantine, and transparent disclosure of information while announcing a National Guideline to practice aggressive prevention policies. Consequently, the government changed its social distancing policy into casual-distancing-in-daily-lives policy. However, on the very day when the new policy started, a new male patient who has visited a club in Itaewon, Seoul, was confirmed to denote the start of club infection. This incident bore three problems for Korea. Firstly, infection without symptoms, which can spread the virus with only slight or no symptoms at all, can increase. Secondly, the fourth infection has occurred due to local spread by confirmed cases related to the club infection. Thirdly, the change of awareness among 20’s and 30’s is required to shorten the COVID-19 situation. As there is no established cure for COVID-19, both the government and the public should be careful.
The present research focused on the isolation and selection of identical bacteria from two different estuaries such as polluted (Uppanar) and marginally polluted (Vellar). The comparative assessments were made on their mercury resistant and antibiotic resistance capacity. Based on the biochemical and molecular techniques the selected bacterial strains CASKS4 and CASKS2 were tentatively identified as Bacillus anthracis. Growth pattern of the selected strains in the presence of mercury was assessed and further mercury removal capability of the strains was investigated. CASKS4 and CASKS2 remediate the mercury at the level of 57.76%, 40.88%, 30.24%, 24.88% and 45.92%, 36.16%, 28.15%, 21.69% respectively, at concentrations of 25mg-l, 50 mg-l, 75 mg-l and 100 mg-l. In addition with mercury removal, antibiotic susceptibility of the strains were assessed, CASKS4 expose their susceptibility to Erythromycin, Novobiocin, Oxytetracyclin, Vancomycin, Amikacin and CASKS2 represents susceptibility to Oxytetracylin, Erythromycin, Novobiocin and Amikacin. The notable finding of the present study is the strain (CASKS4) screened from polluted estuary, showed higher mercury resistant but lower antibiotic resistance, another strain (CASKS2) screened from marginally polluted estuary exhibited lower mercury resistance and higher antibiotic resistance.
