Quasi-isochronous storage ring

In tins article we study the possibility of designing storage rings with a reduced by two or more orders of magnitude with respect to existing rings, thus making the bunch length shorter by a factor of 10 or more . We will, with an appropriate design, show that this bunch length reduction can be achieved while simultaneously increasing the beam peak current. With this approach one can increase ...

On α Quasi-Set Theory

The main features of a theory that enables us to deal, in terms of a set theory, with collections of indistinguishable objects are presented. The fundamental idea is to restrict the concept of "identity" in the underlying logical apparatus. The basic entities of the theory are Urelemente of two sorts; to those called w-atoms, the usual concept of identity, in a precise sense, does not apply, bu...

Photosonochemical catalytic ring opening of α-epoxyketones

The combination of ultrasound and photochemical methods has been used for the catalytic ring opening of alpha-epoxyketones by 1-benzyl-2,4,6-triphenylpyridinium tetrafluoroborate (NBTPT) as photocatalyst in methanol. Sonication of these compounds in the presence of NBTPT did not result in the opening of epoxide ring, but the use of ultrasound increased the rate of photoreaction.
