Introduction: COVID-19 is a disease caused by SARS-CoV-2 that progresses with a predominance of respiratory symptoms.Studies have elucidated to clarify the pathophysiology and clinical manifestations resulting from viral infection, in view of the repercussion of the theme and its notoriety worldwide.Although the respiratory system is the primary fo
The organosilicon derivatives of Step Platform 2 -[ 1 -( 2 -furayl)ethyledene]sulphathiazole with organosilicon chlorides have been synthesised and characterized on the basis of analytical, conductance, and spectroscopic techniques.Probable trigonal bipyramidal and octahedral structures for the resulting derivatives have been proposed on the basis
This study aimed to determine the suitable inactivation conditions of ultrasound and other five methods [heat, low pH, high pH, gamma irradiation and supercritical carbon dioxide (CO2)] to obtain paraprobiotics from Lactobacilus acidophilus, Lacticaseibacillus casei and Bifidobacterium animalis.The impact of each method at distinct conditions of in
The paper presents the results of investigation on ambient air quality evaluation with respect to concentration of odorants in a vicinity of a sewage treatment plant of the LOTOS Group S.A.petroleum plant.The investigation was performed during winter season using a prototype of electronic nose and the Nasal Ranger field olfactometers.The prototype
