This review deals with computer simulation of biological aging, particularly with the Penna model of 1995. They are based on the mutation accumulation theory of half a century ago. The results agree well with demographical reality, and also with the seemingly contradictory influence of predators on the aging of prey.

Accumulation of contextual data offers new opportunities to improve the preventative health and wellbeing interventions. In this paper, we discuss the importance of understanding the context elements of Behavior Change Support Systems (BCSSs) and present an Event model illustrating the Use, User and Technology Context factors of the Persuasion Context. The model is a conceptual tool for identif...

dust accumulation capacity of ficus carica l. and psidium guajava l. was investigated from eight different sites of multan, pakistan.  leaves of both plants were used for analyzing biometric (leaf area, fresh and dry weights) and biochemical attributes (chlorophyll contents, carotenoids and ascorbic acid).  maximum dust accumulation was occurred in the plants growing near road sites, while, min...

This study was undertaken to find out the interpretation learning strategies employed by successful interpretation learners to achieve the completeness of interpretation. The results showed that, to achieve the completeness of interpretation, they employed knowledge-accumulation, summarization, note-taking and logical-analysis learning strategies, among which the first three learning strategies...

In the present study, cadmium (Cd) accumulation capabilities of aquatic macrophytes Ceratophyllum demersum, Bacopa monnieri and Rotala rotundifolia were determined after treating both individual and triple macrophytes. The macrophytes were treated with Cd at 0, 0.1, 1 and 10 mg/L concentrations in a controlled chamber for 12-days. Cadmium accumulations increased with increasing Cd concentration...
