Manilkara hexandra is a traditionally used medicinal plant. The aim of the present study was to analyze in vitro antioxidant potentials of the methanolic leaf (LMEMH) and bark (BMEMH) extracts of M. hexandra in relation to total phenolics. Here, in v

Coupled rotors can spontaneously synchronize, giving rise to a plethora of intriguing dynamics. We present here a pair of spiral waves as two synchronizing rotors, coupled by diffusion. The spirals are pinned to unexcitable obstacles, which enables u

Rotors of reaction and diffusion, that revolve around a circular singularity, and the corresponding spiral wave activity around it, influence the nature of several excitable media. Their dynamics are known to be affected by target waves and external

Two scroll rings, placed in close proximity, can interact. When they come within one core length of each other, these waves can reconnect to form a single, large filament. In this article we show that three or more scroll rings can also reconnect whe

Scroll waves in reaction diffusion systems can be pinned to several unexcitable heterogeneities. The stable pinned filaments have highly enhanced lifetimes. An external gradient can be applied to unpin the scroll waves sequentially from the anchoring

A detailed study of the effects of excitability of the Belousov-Zhabotinsky (BZ) reaction on spiral wave properties has been carried out. Using the Oregonator model, we explore the various regimes of wave activity, from sustained oscillations to wave

Spirals or scroll wave activities in cardiac tissues are the cause of lethal arrhythmias. The external control of these waves is thus of prime interest to scientists and physicians. In this article, we demonstrate the spatial control of scroll waves
