Balloons and coils: aids in particulate/liquid head-neck embolization.

In embolization procedures of the external carotid artery (ECA) system, it is ideal to selectively embolize only the involved feeding branch or branches. This usually requires superselective catheterization , which can be difficult. The catheter diameter may approximate vessel diameter closely enough to reduce flow. Vessel spasm may be generated by catheterization attempts. Spasm may lead to re...

Experimental Investigation of Cryogenic Cooling by Liquid Nitrogen in the Orthogonal Machining Process

The most emerging needs of the modern metal cutting operation are to increase the material removal rate with better surface finish and high machining accuracy. These objectives can be achieved by reducing cutting temperature in the cutting zone. In metal cutting process, high cutting temperature and its detrimental effects are generally reduced by proper selection of process parameters, proper ...

Preservation of T2 Bacteriophage with Liquid Nitrogen.

There have been few reports on the preservation of viruses at the temperature of liquid nitrogen (-196 C). In this study, factors affecting the survival of phage were observed. Phage lysates in broth did not lose titer after a storage period of 4 weeks in liquid nitrogen. The rate of freezing was not critical, but freezing in nitrogen vapor was not satisfactory. When the virus was partially pur...

Algorithmic Cooling in Liquid State NMR

Algorithmic cooling is a method that employs thermalization to increase qubit purification level, namely it reduces the qubit-system’s entropy. We utilized gradient ascent pulse engineering (GRAPE), an optimal control algorithm, to implement algorithmic cooling in liquid state nuclear magnetic resonance. Various cooling algorithms were applied onto the three qubits of C2trichloroethylene, cooli...

Prebreakdown events in liquid nitrogen

2014 It was shown previously that a small volume of liquid nitrogen in front of a sharp metal tip can withstand an extremely high field without any sign of breakdown or charge injection. Subsequently, the influence of the tip radius on the critical field has been investigated and is described here. Also, by monitoring the injection, it has been possible to analyse the influence of the injected ...
