The phenomenon of prebifurcation noise amplification is proposed as a promising indicator of bifurcations (“noisy precursor”) in nonlinear processes in Geophysics. This phenomenon arises due to decreasing of damping coefficients just before bifurcation. A simple method for the estimation of the forced fluctuation variance is suggested which is based on results of linear theory up to the boundar...

background: we have previously reported multiple health benefits in individuals following the christian-based fasting protocol known as the daniel fast (df). however, our prior work has involved only short-term (21-day) assessments. for dietary modification to have a profound impact on health, compliance to the dietary plan must be established for the long-term. materials and methods we determi...

Ornamental fish sector is considered a large international market and parasitical diseases cause a serious damage on this trade’s profits. This study was conducted to investigate the use of garlic (Allium sativum) and chamomile (Matricaria chamomilla) aqueous extracts on suppression of Ichthyophthirius multifiliis parasite in guppy fish (Poecilia reticulata). Two experimental groups consisted o...

The estimation resulted through the combination of ECM and WLS shows that the price of export goods/merchandises has a positive effect and is significant in the short-term period. Yet, over the longterm period, the increase in export commodity price causes the decrease in export volumes. Meanwhile, the relationship between export volume and inflation is not significant, either in the short-term...

Sea cucumber catch has followed “boom-and-bust” patterns over the period of 60 years from 1950-2010, and sea cucumber fisheries have had important ecological, economic and societal roles. However, sea cucumber fisheries have not been explored systematically, especially in terms of catch change trends. Sea cucumbers are relatively sedentary species. An attempt was made to explore whe...

Here it is shown that chaotic oscillations can appear after a series of period doublings in radiating diffusion flames when the activation temperature is high enough. It is also shown that period doubling cascades appear typically in very small regions and that they may not be observable if one starts with small perturbations of a steady flame.
