there are many methods for weed management one of them is putting allelopathic and cover crop in weed management programs. in order to study the effect of sowing time (delayed sowing, synchronic sowing) and wheat cultivars (shiraz, roshan, tabasi, niknejad) on allelopathic interaction of wheat and weed species (secale cereale l., avena ludoviciana l.: monocotyledon, convolvulus arvensis l. and ...

Previous studies have demonstrated that peripheral denervation of the skin is reflected in the CNS as a reorganization of somatotopic representations. In cases in which peripheral nerve regeneration occurs there is a gradual reactivation of cortex by novel receptive fields that is reversed as regenerated nerves reestablish connections with the original skin surface. Functional recovery appears ...

Recruitment into peripheral possession trance cults has been explained as attempts to compensate for socio-economic deprivation and jural impotence. This model, best developed by I. M. Lewis, is reviewed and its predictions are tested against two types of Brazilian data. Firstly, national census Žgures of religious afŽliation are compared with measures of socio-economic stress for a diachronic ...

Swarm is a computational model which extends UNITY in three important ways: (1) UNITY's fixed set of variables is replaced by an unbounded set of tuples which are addressed by content rather than by name; (2) UNITY's static set of statements is replaced by a dynamic set of transactions; and (3) UNITY's static IIcomposition is augmented by dynamic coupling of transactions into synchronic groups....

piezoelectric microcantilevers (mcs) are a new generation of microbeams used in atomic force microscopes (afms). due to their miniaturization of afms as well as their increased imaging precision and speed, these mcs are more popular than their classical counterparts. given the widespread application of these beams in nanoparticle topography, analysis of their vibrating motion has attracted much...
