Today, planting winter cover crops to reduce herbicide is high considered. The purpose of this study was to examine the effect of barley grass cover crop on control weed of flix weld (Descurainia Sophia). This experiment was conducted at agricultural farm of Rezvan Junior College in kerman provinces (latitude 25 55 / N, longitude 53 26 / E , altitude 1755m) from September 2010 to April 2011. A ...

background wart is a skin disease with circular appendages, which is called “suloul” in iranian traditional medicine (itm). according to itm literature, warts have different types and causes. the most important mechanism is excretion of materials (khelt) from body to skin and mucus; its causative material is often phlegm, black bile or a combination of them. to treat warts, it is necessary to c...

Background: Water treatment sometimes needs a coagulation and flocculation process to remove suspended and colloidal materials. Inorganic coagulants used create concerns about pollution of the environment and harmful effects on the human’s health. The studies carried out previously indicated the capability of an active coagulant agent extracted from Descurainia Sophia seed to remove turbidity o...

Allelopathy offers potential for weed control through the production and release of allelochemicals from leaves, flowers, seeds, stems and roots.  In this research, allelopathy potentials of ethanolic and aqueous extracts of Vinca rosea L. leaves were evaluated. Three extract concentrations, including 2.5, 5 and 10% (w/v) of both aqueous and ethanolic were prepared from a 10% w/v stock solution...

today, biosphere pollution has accelerated strongly with start of industrial revolution by toxicity of heavy metals. one of existing pollution is soil pollution. unfortunately, soil pollution by metals is as intensive environmental stress for plant hence for human. plants, which are able to store heavy metals in their organs, can be used for phytoremediation of polluted soils and utilization of...

The mode-locking structure of the sine circle map is investigated using the method of modular smoothing. It is shown that the method leads to a scaling function generated by the Gauss transformation. We speculate about a recursive procedure to obtain increasingly smooth descriptions of the fractal structure based on this method. T HE quasiperiodic transition to chaos in families of maps on the ...
