A 75-year-old Hispanic woman with no significant past medical historywas referred to uswith a 2-month history of very itchy dermatitis involving the eyelids, chin, and the anterior part of the ears. Clinical features suggested an airborne contact dermatitis. However, patch testing with the North American baseline series gave negative results. Further patch tests with fragrances and cosmetic and...

drought stress is one of the most important factors limiting the survival and growth of plants in the different habitats of iran. detailed knowledge about the ecophysiological responses of native plants to drought stress could contribute to the success of breeding and re-vegetation programs. six wild populations of anthemis tinctoria, were assigned to four drought treatments, i.e. well-watered ...

In this study, common weed species (Anthemis sp., Anthemis tinctoria L., Pilosella hoppeana Schultes, Doranicum orientale Hoffm, Muscari neglectum Guss. ex Ten., Ornithogalum armeniacum Baker, narbonense wiedemannii Boiss., Anchusa azurea Miller, Echium plantagineum vulgare Ajuga orientalis Stachys germenica Juncus Anacamptis pyramidalis Ophrys apifera Huds., Carex panicea Ranunculus Hypericum ...

A field experiment was established to evaluate quantitative changes in weed species prevailing a crop rotation and 30-year cereal monoculture. The subject of the study included cropping systems: a) rotation, b) First (1989–1992) second (1993–1996) focused on infestation winter triticale monoculture; third (1997–2000) fourth (2001–2004) wheat; fifth (2005–2008), sixth (2009–2012), seventh (2013–...

This paper analyses the behavior of a hardware implementation of Genetic Programming using Field Programmable Gate Arrays. Three crossover operators that limit the lengths of programs are analyzed. A truncating operator, a limiting operator that constrains the lengths of both offspring and a limiting operator that only constrains the length of one offspring. The latter has some interesting prop...
