quaternary ammonium compounds (qacs) are employed both as disinfectants for manual processing lines and surfaces in the food industry, and in human medicine area. qacs also cause cell death by protein denaturation . one of the qac is cetyl trimethyl ammonium bromide (ctab) that appears to rapture the cell membrane. the primary site of action of ctab has been suggested to be the lipid components...
Quaternary ammonium compounds (QACs) are disinfection agents used in industrial cleaning processes that known to interfere with the proper functioning of anaerobic waste digestion directly impacting quality and quantity biogas produced (i.e., CO2 CH4). While impact these contaminants on digestors well known, have metabolic profile an digestor is less understood. This paper describes use nuclear...
Surfaces in an outpatient setting are exposed to multiple patients b ecome colonized with microorganisms. Copper and alloys containing greater than 60% copper reduce bacterial burdens on solid surfaces by 99.9% within 2 hours.! Copper surfaces have been found to substantially diminish the density of bacte ria to levels below those considered a risk to patients for the acquisition of an infectio...
Nowadays the provision of safety food products for human health, including animal origin, is extremely important in world. Since 2007, Russian Federation has been monitoring and feed order to protect public assess veterinary imported domestic raw materials, its processing feed, as well develop measures prevent entry dangerous into market relation origin feed. One main factors production high sa...
The unmanned aerial vehicle (UAV) trajectory tracking control algorithm based on deep reinforcement learning is generally inefficient for training in an unknown environment, and the convergence unstable. Aiming at this situation, a Markov decision process (MDP) model UAV established, state-compensated deterministic policy gradient (CDDPG) proposed. An additional neural network (C-Net) whose inp...
Methicillin Resistant Staphylococcus aureus (MRSA) is a main cause of severe human infections. The aim this study was to detect chlorhexidine resistance MRSA by phenotypic and genotypic methods. Fifty strains were isolated from different hospitals Mansoura University over period one year December 2021 till November 2022. antimicrobial susceptibility test conducted the disk diffusion method, exc...
