 In this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. We extract the information function ofan ergodic dynamical system (X,T) from the relative information of T fromthe view point of observer χX, where X denotes the base space of the system.We also generalize the in...

The Barrel CRID detector has been operating successfully at SLD for the past 7 years. It is an important tool for SLD physics analyses. We report results based on long term operational experience of a number of important quantities such as the Cherenkov quality factor, No, of the device, fluid transparency, electron lifetime, single electron detection efficiency, anode wire ageing,TMAE purity, ...

the vase life of cut flowers and foliage is often shortened by vascular occlusions that constrict vase solution supply. reduction in stem conductivity is typically caused by blockage of cut stem ends and xylem conduits by microbes, physiological plugging, and disruption of water columns in xylem vessels by cavitations and air emboli. cut flower and foliage longevity can be greatly affected by t...

in order to assess the drought tolerance in 15 lentil genotypes, a field experiment was conducted during 2001-02 growing season in dryland agricultural research institute (dari) station of shirvan, in northern khorasan, iran, under rainfed and irrigated conditions. the experimental design was rcb with three replications. data for agronomic traits of plant height, number of empty and filled pods...

In this research, the rheological behavior and stability of suspensions containing Si3N4, Al2O3, Y2O3 and starch were investigated in order to use them in the starch consolidation casting of porous silicon nitride. Dolapix CE64 was used as the dispersant. Then, the effect of some parameters such as Si3N4 surface oxidation, dispersant content, solid loading and starch content on the viscosity an...

Soil salinity is one of the important and determinant factors in land degradation and desertification. This study was undertaken to investigate salt tolerance in Salsola tomentosa under greenhouse conditions to choose a suitable species for saline conditions. The treatment solutions for salinity tests were different concentrations of NaCl (0, 100, 200, 300, 400, and 500 mM) with three replicate...

plant growth is often limited by low levels of soil micronutrients such as copper (cu), ‎especially in calcareous salt-affected soils of arid and semiarid regions. the aim of this ‎work was to investigate individual and combined effects of salinity and cu on growth, leaf ‎relative water content (lrwc), cell membrane permeability, lipid peroxidation, and total ‎phenolic content (tpc) of rosemary...
