THE ROLE OF AIR ADVECTION AND ATMOSPHERIC STABILITY INDICES FOR IDENTIFING HEAVY RAIN STORMS IN NORTH-WESTERN ROMANIA [PDF]
Air advection and convection at different levels in the atmosphere affect its vertical stability. The degree of stability / instability can be determined by using vertical wind profile (hodograph) and stability indices. Analysis of these two elements was

Modelling for JET Vertical Stabilization System [PDF]
Nuclear fusion is, in a sense, the opposite of nuclear fission. Fission, which is a mature technology, produces energy through the splitting of heavy atoms like uranium in controlled chain reactions.

Baroclinic instability in the two-layer model: interpretations
Two new interpretations of the wellknown instability criterion of the two-layer model of baroclinic instability are given whereby also a slight generalization of this model is introduced by admitting an interface on top with a reduced gravity g.

Beam ion instability: Measurement, analysis, and simulation
A weak vertical coupled-bunch instability with oscillation amplitude of the order of a few μm has been observed in SPEAR3 at nominal vacuum pressure. The instability becomes stronger with increasing neutral gas pressure as observed by turning off vacuum ...

The vertical shear instability in poorly ionized, magnetized protoplanetary discs [PDF]
Protoplanetary discs should exhibit a weak vertical variation in their rotation profiles. Typically, this ‘vertical shear’ issues from a baroclinic effect driven by the central star’s radiation field, but it might also arise during the launching of a ...

In the CTF3 (CLIC test facility 3) run of November 2007, a vertical beam instability has been found in the combiner ring during operation. After a careful analysis, the source of the instability has been identified in the vertical deflecting modes ...

Experiments on a barotropic rotating shear layer. Part 1. Instability and steady vortices [PDF]
The barotropic shear layer in a rotating fluid is studied in a laboratory experiment. Through the rotation of circular sections in the base and lid of a circular tank relative to a background rotation of the entire system, a vertical layer of strong ...

The streaming instability is a promising mechanism to induce the formation of planetesimals. Nonetheless, this process has been found in previous studies to require either a dust-to-gas surface density ratio or a dust size that is enhanced compared to ...

Effects of non-rigidity on fast plasma boundary control using in-vessel coils in JT-60SA
An effective fast plasma position control (FPPC) method using in-vessel poloidal field coils and capable of maintaining high-elongation plasma, and hence high vertical instability growth, was developed utilizing an magneto-hydrodynamic equilibrium ...

Enterotoxigenic Bacteroides fragilis is a gut bacterium linked to bowel cancer. We propose that its toxin acts along two routes: at the cell surface, cutting the adhesion protein E‐cadherin and triggering inflammation; and inside the cell, delivered by bacterial vesicles, switching on NOD1 and cancer stem cell programs.
