Methods for the mass isolation of diverse organs from small animals are described. They involve novel devices: a mechanical dissecting system, a centrifugal agitator for the separation of fibrillar from globular particles, and a settling chamber for the fractionation at unit gravity of particles with sedimentation velocities above the useful range for centrifugation. The application of these me...

Oxygen transfer has been studied in the Pseudomonas ovalis fermentation that quantitatively converts glucose into gluconic acid. The rate of oxygen uptake by this system was correlated with aeration rates and agitator speeds over wide ranges of these variables, by the introduction of a liquid expansion term. The technique described provides a biological method for studying oxygen transfer in th...

Abstract In this article, the side-entry agitator commonly used in wet desulfurization absorption tower of a 300 MW thermal power unit was taken as research object, and gas–liquid two-phase flow field stirring tank numerically simulated by using two-fluid model based on Euler–Euler method. The vertical horizontal velocity distribution gas phase were studied. results showed that formed “fountain...

Notwithstanding the numerous studies in the last decades to prevent runaway reactions, the maintenance of stability in chemical reactors is still a current issue in industrial chemical plants. There is an urgent need to implement an efficient and robust algorithm capable of detecting in advance anomalous behaviours of the reactor temperature during exothermic processes, in order to take appropr...

Thromboelastography® (TEG®) is used to guide clinical decision-making across many medical and surgical subspecialties. Advances in this field have resulted in analyzers becoming increasingly user friendly, and have led to a reduction in the possibility of user error. The new TEG®6s does not come with the warnings of vibration and movement avoidance of its predecessor. It was decided to test the...
