Background: Patients contaminated with the new coronavirus, SARS-CoV-2, and who develop the severe form of the disease require ventilatory support to maintain adequate gas exchange. The objective of this systematic review was to establish reference parameters of ventilator therapy used in the various levels of severity of adult patients affected by COVID-19 to assist health professionals and hospital managers who will purchase this equipment. Methods: It used four databases: Medline, Cochrane Central, Scielo, and Pubmed. Restrictions applied as to the language, restricted to English, and to the patient’s profile, only adults affected by SARS-CoV-2. The review process was carried out by three independent reviewers using the PRISMA-P method. Results: Nineteen articles were included, in addition to the recommendations of the Brazilian Association of Intensive Care Medicine (Brazil), Federal Commission for Protection against Health Risks (Mexico), Medicines and Healthcare Products Regulatory Agency (UK), Pan American Health Organization, and World Health Organization. The types of ventilatory therapies found in the articles eligible for this study were continuous positive airway pressure (CPAP), non-invasive ventilation (NIV), and invasive mechanical ventilation (IMV). For each ventilatory therapy, the parameters presented in the article and the recommendations of regulatory agencies and relevant institutions were compared and analyzed. Conclusion: It was possible to suggest a relationship between the respiratory support strategy adopted by the clinical team and the clinical conditions of the patient infected with SARS-CoV-2. The included studies used ventilation modes and parameters within the specifications and recommendations of relevant regulatory agencies and institutions. However, some minor differences were observed in the instruction presented among the agencies more related to the recommended ventilation modes. Further studies are needed. © 2021, Sociedade Bras

The available prophylactic vaccines for human papillomavirus (HPV) in the market are only effective against specific types of HPV, rendering them ineffective for other types of HPV infections. The objective of this research is to investigate the stability of the recombinant protein constructed, namely chimeric L1/L2 protein from HPV type 52, with improved cross-neutralization ability. The 3D model, predicted using Alphafold, Robetta, I-Tasser, and refined with Galaxy Refinement, is validated using Ramachandran plot analysis. The stability is verified through molecular dynamics simulations, considering parameters such as RMSD, RMSF, Rg, and SASA, where stable conditions are observed. The chimeric L1/L2 protein from HPV type 52 is purified using affinity chromatography, and the His-tag is cleaved using SUMO protease to obtain pure chimeric protein with the size of ~ 55 kDa. Western blot analysis confirms binding to anti-L1 HPV type 52 polyclonal antibody. The obtained vaccine candidate can be utilized as an effective prophylactic vaccine against HPV. © 2024 Taylor & Francis.

Coal-fired power plants are major contributors to global CO2 emissions, prompting the need for strategies to mitigate their environmental impact. Ammonia co-firing has emerged as a promising solution for reducing CO2 emissions. This study employs computational fluid dynamics (CFD) simulations to optimize ammonia injection in a 1000 MW Ultra Super Critical Coal Fired Power Plant. Initially, four injection locations (equally divided, top burner, bottom burner, mid burner) were simulated at a 20% thermal energy co-firing ratio. The bottom burner injection showed the lowest NOx emissions. Building on these findings, the focus shifted to varying injection locations, particularly the bottom burner. Increased co-firing ratios led to reduced gross power and derating due to altered heat absorption and water content from ammonia combustion. Flue gas properties and composition were affected. NOx emissions showed a complex trend with initial reductions up to 20% due to ammonia's effect, but exceeding 20% co-firing led to dramatic NOx increases, surpassing limits at 60% co-firing. Burnout ratio linearly increased due to low unburned ammonia. However, coal burnout exhibited a different pattern, initially increasing, then declining after 40% co-firing. This was attributed to the char-NO reaction counteracting decreased coal volatilization caused by high ammonia levels. © 2023, The Authors. All rights reserved.

In general, public or private organizations or companies have used information-based technology as a support to improve business performance to be more effective and efficient in order to achieve a company's business goals. Given the large contribution of information technology in the application of hotel applications as a supporting information system, it is a vital system that must avoid risks that can hinder and cause harm to the hotel management business processes. Therefore, it is necessary to carry out risk management using the COBIT 5 framework to manage possible risks that may occur based on the APO12 (Manage Risk) domain. From the evaluation results of the data obtained through observation and interviews as well as the calculation of the results of the questionnaire based on 6 APO12 subdomains, the results of the risk management level capability assessment in hotel applications are still at level 3 or have reached the level of established process with the target to be achieved at level 4 resulting in a gap of 1 level. Based on the results obtained, it is necessary to propose recommendations that can be used by hotels in improving the application of information technology risk management so that in the future it can achieve the expected target level so that the APO12 level of capability can increase and become more optimal. © 2023 IEEE.
