Such semi-regular instability is not experienced in temperate climes, and it has deep repercussions.In this section Seasons of discontent Clouds in a jar A wide spread problem Heady discoveries ReprintsIn years of El Niño, the researchers found, the annual risk of conflict in their 93 tropical countries was 6%.
Cell lines, particularly continuous cell lines, are prone to genotypic and phenotypic instability requiring regular characterisation and replacement from cryopreserved stocks.
Once the initial population is established where all the individuals are free of instability problem, the regular genetic operations are applied to generate a new population.
This type of combination of the negative and positive feedback loops with a possible diffusible inhibitor is reminiscent of Turing instability dynamics for regular pattern generation [14], although this and other possibilities have not yet been well validated experimentally.
Here, as in many parts of rural Afghanistan, harsh weather, inadequate roads and political instability hamper the regular provision of social services, including health care.
Modelling, 49 (9–10) (2009) 1759 1780] we identified criteria to recognize PDE's that are stable (in extended Ulam sense) and in their regular smooth solutions, finite time instabilities do not occur (stable extended crystal PDE's).
The focus of this investigation is on the jet screech phenomenon resulting from the interaction between the large-scale turbulent mixing region instabilities and the regular spacing of the shock wave-expansion system, (shock cells), in the over-expanded jet.
In previous studies, analyzing of parametric instability is mainly limited to regular waves, whereas the realistic sea conditions are irregular waves.
And when regular diplomacy breaks down because of hostility or instability, museums feel the impact.
Tea-brokers in Mombasa, Kenya's second city, whose port serves most of east Africa, say that another month of instability could ruin the city's regular auction of one the country's main exports.Asian Kenyans are especially jittery.
