in order to study the characters affecting grain yield of lentil, a randomized complete block design with three replications conducted at dryland research station of northern khorasan (shirvan) in year 2002-2003. during the growth season and after harvesting, number of days to emergence, days to 50 percent flowering, days to maturity, number of primary and secondary branches, small and big diam...

067004-1 We have directly observed well-separated Josephson vortex splinters with unquantized magnetic flux at asymmetric 45 grain boundaries in YBa2Cu3O7 films by imaging magnetic flux with scanning SQUID microscopy. The existence of these splinter vortices has been predicted and is well described by a model based on dx2 y2 pairing symmetry and facetting of the grain boundary on a length scale...

In this paper we demonstrate how to use the importance sampling method to simulate rare events in a germ-grain model. We analyze conditions under which two germ-grain models are mutually absolutely continuous. We also find the likelihood set process. We apply these results in simulating the probability that the radius of the occupied component of the origin in continuous percolation is greater ...

In this paper, cyclic flaring and sinking (CFS) as a new severe plastic deformation (SPD) method was employed to produce the ultrafine grain (UFG) copper tubes. The extra friction has eliminated in the CFS method that provided the possibility for production of longer UFG tubes compared to the other SPD methods. This process was done periodically to apply more strain and consequently finer grain...

We present a three-dimensional computer model that simulates ear temperatures under field conditions for both daytime and night-time. The meteorological data used are total and diffuse radiation, wind speed, air temperature and humidity (or wet bulb temperature). The model is based on the energy variation of volume elements on ear surface. It takes into account, net radiation, sensible and late...
