Cxv. a Wet-crushing Mill for Micro-organisms
FOR some years we have been engaged on the problem of extracting enzymes from micro-organisms. It is well known that most bacteria and yeasts carry out oxidations and metabolic processes at a rate incomparably higher than that of animal tissues. The peculiar virtue of micro-organisms as the source of enzymes is therefore self-evident. A certain amount of success has been attained in extracting ...
متن کاملOptical Forces and Torques Acting on Non-spherical Metallic Nanoparticles
Metallic nanoparticles (NPs) are nowadays used in various areas of biology, chemistry or physics, e.g. they are used as a heat source causing hybridization of DNA or probes for surface enhanced Raman spectroscopy. Focused laser beams, so-called optical tweezers [1], are widely used to manipulate dielectric particles or even living cells. Optical tweezers may be used as well to manipulate metall...
متن کاملCrushing analysis of the industrial cage mill and the laboratory jaw crusher
Many research studies have been conducted on the liberation of locked minerals using a crusher and comparing this device with the other devices. This paper reviews the liberation of middle coal by different methods of crushing force. In the Tabas coal washing plant, particles of 0.5-50 mm size are processed through the heavy media method (using 3 Tri-flo separators) and particles of 0-0.5 mm si...

متن کاملStrongly stable gyroscopic systems
Here, gyroscopic systems are time-invariant systems for which motions can be characterized by properties of a matrix pencil L(λ) = λ2I + λG − C, where GT = −G and C > 0. A strong stability condition is known which depends only on |G| (= (GT G)1/2 ≥ 0) and C. If a system with coefficients G0 and C satisfies this condition then all systems with the same C and with a G satisfying |G| ≥ |G0| are al...
