We first investigate the general properties of the system and identify all possible wave combinations. Second, a critical investigation of the Riemann problem yields definite results for large data about the existence of Riemann solutions made of Lax shocks, rarefaction waves, and admissible stationary contacts. In some range of Riemann data, no solution exists. We can identify relatively large neighborhoods of Riemann data in which the Riemann problem admits a unique solution.

In this research, Al2O3 nanoparticles were successfully synthesized using facile chemical precipitation method as a photocatalyst. The synthesized photo catalyst was characterized using scanning electron microscopy. The photocatalytic activity of the synthesized Al2O3was studied on the degradation of ciprofloxacin as a model pollutant in UV light irradiation by conductometry method. The experiments were carried out by varying contact time from 1- 5 hours and catalyst load from 0.5 – 2.5g. The optimum catalyst dose and contact time were found to be 1g and 1 hour respectively for the drug degradation. The result exhibited photocatalysis activity. The photocatalytic activity can be attributed to higher absorption of Ultra-Violet light by the synthesized Al2O3 that led to formation of a large number of reactive species. The Kinetics study of the photodegradation process was explained in terms of the modified Langmuir Hinshelwood model. The values of the kinetic rate constant (k) of the photodegradation were 8.0x10-3min-1 and 5.0x10-2min-1in the absence and presence of the synthesized photocatalyst respectively.

Background: Rigid bronchoscopy is frequently required in the therapeutic therapy of a wide range of tracheobronchial diseases. Suxamethonium is a common neuromuscular blocking medication used for rapid sequence tracheal intubation because of its quick onset and recovery. Objective: The objective of the study was to evaluate the effects of single vs multiple doses of Suxamethonium in rigid bronchoscopy. Methodology: This randomized cross-sectional observational study was conducted from January 2019 to December 2020 among 180 patients in a tertiary care hospital of Bangladesh. Data on certain basic parameters were obtained on the basis of the clinical records and related changes. Collected data were displayed in tabular and graphical form in terms of different parameters, and statistical analysis was conducted to observe the statistical significance. Results: In this study, we divided patients into 2 groups (Group 1: Single dose Suxamethonium, Group 2: multiple-dose Suxamethonium). Among 180 patients, a maximum (34.4%) patients were more than 50 years of age. Also, 58% were male, and 42% were female patients. Here, maximum patients (33.8%) had a cough, while minimum patients (2.7%) had chest pain. Among group 1, maximum patients (39.1%) had mild fasciculation scores and minimum patients (7.4%) had zero scores. Among group 2 patients, maximum patients (24.3%) had zero fasciculation score, and minimum patients (6.3%) had vigorous scores. According to the Copenhagen scoring system, in group 1, 47.40% of patients had an excellent outcome, and 6.65% of patients had a poor outcome. And in group 2, 74.7% of patients had a good outcome and 13.50% of patients had an excellent outcome. In both groups, maximum patients had minor bleeding, vocal cord trauma, and hypoxia. Conclusion: The findings imply that single-dose Suxamethonium was more effective in improving patient satisfaction. The intubating settings would be more pleasant if single-dose Suxamethonium was used.

Keratitis is a frequent pathology in everyday ophthalmology, whose etiologies are dominated by bacterial origin.
