A new Modular Recurrent Trainable Neural Network (MRTNN) has been used for system identification of two-mass-resort-damper nonlinear oscillatory plant. The first MRTNN module identified the exponential part of the unknown plant and the second one the oscillatory part of the plant. The plant has been controlled by a direct adaptive neural control system with integral term. The RTNN controller us...

Plant sterols, naturally occurring in foods of plant origin, reduce cholesterol absorption. Experimental studies show plant sterols to be an important part of the serum-cholesterol lowering effect of certain diets and dietary components. Epidemiological data show that individuals with higher intakes of plant sterols from their habitual diets have lower serum-cholesterol levels. To date, the rol...

Cancer is the second cause of death after cardiovascular diseases. With due attention to rapid progress in the phytochemical study of plants, they are becoming popular because of their anticancer effects. The aim of this study was to investigate the effective medicinal plants in the treatment of cancer and study their mechanism of action. In order to gather information the keywords "traditional...

In addition to playing a central role in metabolism, soluble sugars such as Glc and Suc help regulate many developmental and physiological processes in plants (for review, see Koch, 1996; Smeekens, 1998; Sheen et al., 1999; Yu, 1999). For example, sugar levels have been postulated to play an important role in determining the time at which some plant species flower. Treatments that induce flower...

This paper presents the Medical Plant Wealth of Andhra Pradesh based on the results of Medico - Ethno - Botanical exploration undertaken during the last fourteen years (1971 - 72 till the end of 1984). In all, 117 well known medicinal plants widely used in Ayurveda, Siddha and other systems of Medicine are enumerated here.

Soils can serve as sorbents for phosphorus (P), negating the need for artificial sorbents. The purpose of this study was to compare soils with different properties for their effect on nutrient levels in effluent. Four soils were mixed with sand and packed into columns 0.5 m long, with or without compost on the surface. Infiltration and effluent concentrations were measured before and after grow...

The underpinning fundamental challenge of food security is to match supply and demand. In a simple world this challenge would be met by straightforward technology that balances these two market forces. However, we do not live in a simple world. Innovations to save labour in production, for example, would be damaging if they eliminate the only source of personal income for farmworkers. In other ...

In this second part of the study an alphabetical checklist of 211 medicinal plants not covered in the enumeration together with a bibliography is presented here.

The significance of root exudates as belowground defense substances has long been underestimated, presumably due to being buried out of sight. Nevertheless, this chapter of root biology has been progressively addressed within the past decade through the characterization of novel constitutively secreted and inducible phytochemicals that directly repel, inhibit, or kill pathogenic microorganisms ...
