	Title	Effect of Low-Frequency Modulation on Thermal Convection Instability
	Abstract	The stability of a horizontal layer of fluid heated from below is examined when, in addition to a steady temperature difference between the horizontal walls of the layer a time-dependent low-frequency per turbation is applied to the wall temperatures. An asymptotic solution is obtained which describes the be haviour of infinitesimal disturbances to this configuration. Possible stability criteria are analyzed and the results are compared with the known experimental as well as numerical results.

	Title	Self-Organized Criticality and Dynamic Instability of Microtubule Growth
	Abstract	We have shown that the distribution of lengths of site nucleated microtubules obey an algebraic power law relationship D (s) = A s~x, where D(s) is relative number of microtubules with length 5, A and i are constants. This relationship indicates the possibility of a self-organized criticality in the dynamic instability of microtubule growth.
