Hairy root systems are formed by transforming plant tissues with the “natural genetic engineer” Agrobacterium rhizogenes. In most plants such as Cichorium intybus L., hairy root cultures have proven to be an efficient system for secondary metabolites production. The effect of Zinc (ZnSO4), a heavy metal, was investigated at different concentrations (0, 1, 5 and 10 mM) on some secondary metaboli...

The current study assesses the effect of fibrous clay minerals’ amendments and arbuscular mycorrhiza incubation on heavy metal uptake and translocation in Eucalyptus grandis and Ailanthus altissima plants. For doing so, Eucalyptus and ailanthus trees have been grown in a soil sample, contaminated with heavy metal iron ore mining and collected from southern Iran. The area under study is arid, wi...

This article investigates the epistemological foundations of Francis Galton's eugenics based on Max Horkheimer's Critical Theory. Grounded a bibliographical research, we analyze texts in which English polymath structured rationality his science-religion, contrasting them with theoretical-critical diagnosis crisis reason. We conclude that Horkheimer’s argument denouncing enlightened roots eugeni...

In the past ten years there has been increasing interest in rigorous, quantitative analysis of the determinants of civil war, ethnic violence, and other forms of domestic conflict. Scholars have analyzed the impact of ethno-linguistic fractionalization, terrain, economic growth, natural resources, and a variety of other factors. Little attention, however, has been paid to quantitatively estimat...

Stemming is used in many information retrieval (IR) systems to reduce variant word forms to common roots. It is one of the simplest applications of natural language processing to IR, and one of the most eeective in terms of user acceptance and consistent, though small, retrieval improvements. Current stemming techniques do not, however, reeect the language use in spe-ciic corpora and this can l...

One can prove the following proposition (1) For every natural number n holds n = 0 or n = 1 or n ­ 2. The scheme Comp Ind NE concerns a unary predicate P, and states that: For every non empty natural number k holds P[k] provided the parameters satisfy the following condition: • For every non empty natural number k such that for every non empty natural number n such that n < k holds P[n] holds P...
