in order to study the effects of potassium application on uptake and allocation of nitrogen and seed protein on two lentil cultivars in rain-fed condition a factorial experiment based on randomized complete block design with three replications was conducted at ardabil research center for agriculture and natural resources, in 2008. three potassium levels (0, 30 and 60 kg.ha-1), three nitrogen le...

Using a simple pattern finding approach, we investigate to what degree patterns found in the tempo and loudness curves measured from piano performances of a classical piece coincide with repeated musical structures in the score that was performed. We show that high frequency content in such curves is more useful for finding repetitions of musical structures than low frequency content. In some c...

background: phthalates are a group of multifunctional chemicals. diethyl phthalate (dep) is one of the most frequently used phthalates in solvents and fixatives for numerous industrial products. method: the present experiment was designed to assess oxidative stress, if any, caused by diethyl phthalate. for this the homogenates of liver and kidney were treated with different concentrations ( 10-...

background and objective: microbial protein production can resolve one of the major world challenges, i.e. lack of protein sources. candida tropicalis growth was investigated to specify a medium to reach the highest cell proliferation and protein production. material and methods: fractional factorial design and the index of signal to noise ratio were applied for optimization of microbial protei...

This paper presents a standards-based architecture for a complex and generic distributed multimedia scenario, which combines content search and retrieval, DRM, and context-based content adaptation together. It is an innovative and totally generic approach trying to narrow the semantic-gap by integrating a fl exible language for multimedia search based on MPEG Query Format (MPQF) standard with t...
