to study the effect of soil moisture variation on growth and steviol glycosides contents in stevia (stevia rebaudiana b), a potexperiment based on a randomized complete design with four treatments and three replications were conducted in a greenhouse of agricultural biotechnology research institute of iran (central region, isfahan), in 2012. experimental treatments applied as a combination of v...

soil moisture retention curve is one of the soil hydraulic prosperities which its direct measurement is time consuming and expensive. therefore, indirect methods such as developing pedotransfer functions have been used to predict this characteristic from soil readily available or easily measurable data. in this study, multiple linear regression method was used to develop point pedotransfer func...

abstract- annual medicago species (medicago spp.) are native to the mediterranean region and widely used in fields and pastures in iran. there are several methods of sowing annual medicago species, each with different effects on the performance. however, there is currently no sufficient information about the appropriate methods for sowing medicago species. in order to evaluate methods of sowing...

It is important to seek out plant species, high in phosphorus (P) uptake, for phytoremediation of P-enriched environments with a large amount of organic P (Po). P assimilation characteristics and the related mechanisms of Polygonum hydropiper were investigated in hydroponic media containing various concentrations of Po (1-8 mmol L(-1)) supplied as phytate. The mining ecotype (ME) showed signifi...

In this paper we report the stepwise preparation and the characterization of new unsymmetrical monoanionic Ru(III) dinuclear compounds, [NH(4)][{trans-RuCl(4)(Me(2)SO-S)}(mu-L){mer-RuCl(3)(Me(2)SO-S)(Me(2)SO-O)}] (L = pyz (1), pym (2)). By a similar synthetic approach we also prepared new mixed-valence Ru(III)/Ru(II) dinuclear compounds of formula [NH(4)][{trans-RuCl(4)(Me(2)SO-S)}(mu-pyz){cis,...

Let me begin with a couple of general remarks that framed my reading of the papers of this session. First of all, all of them engage in complex and incredibly potent layers of analyses. There is no way for me to do full justice to the wealth of material and theoretical content in such a small space. Second, coming from a totally different discipline (architectural history, theory and criticism)...

‘‘Daddy, tell me a story. A good one.’’ An engineer pauses at the request. We know how to measure and build many things. But imagining, crafting, and telling a story? That is hard. If you are building or researching any aspect of multimedia, however, then you should be thinking about how your work helps both you and the user experience a story. Telling stories is an important part of how we com...
