to study the effects of priming on seed germination traits of sainfoin 'eski', a factorial in randomized complete block design with three replications was conducted at the laboratory of agricultural research center of sari in 2011. treatments consisted of polyethylene glycol (peg6000) at 5 and 10%, potassium nitrate (kno3) at 5 and 10% and potassium chloride (kcl) at 5 and 10% levels ...

[1] A numerical model of the low-altitude energetic electron radiation belt, including the effects of pitch angle diffusion into the atmosphere and azimuthal drift, predicts lifetimes and longitude-dependent loss rates as a function of electron energy and diffusion coefficient. It is constrained by high-altitude ( 20,000 km) satellite measurements of the energy spectra and pitch angle distribut...

We have observed a stellar occultation of GSC5249-01240 by Saturn's north polar region on November 20, 1995 from NASA's Infrared Telescope Facility (IRTF). This is the first recorded occultation by the polar region of a giant planet. The occulted region extends 88 km in vertical height and 660 km in horizontal length, over a region from 82.5 to 85 degrees in planetocentric latitude and from 20 ...

Pose uncertainty estimation of calibrated cameras is a common task in the field of computer vision and uses location uncertainties of image features. For spherical cameras, those uncertainties cannot be optimally described using conventional latitude-longitude representation. Increasing distortions close to the poles of the spherical coordinate system prevent a suitable description through Gaus...
