The Caspian Kutum, Rutilus Kutum (Kamensky 1901) specimens were sampled by purse seine in the northern Iranian coast of the Caspian Sea at four locations:  Feridoonkenar Shahed, Mahmoudabad Khoram, Lariim Azadi fishing coop, and the Shiroud River in Ramsar city. “Back-calculation” is a retrospective method of estimating the characteristics of growth of fish in terms of length and rate of growth...

We analyse and improve a recently-proposed two-phase ow model for the statistical evolution of two-uid mixing. A hyperbolic equation for the volume fraction, whose characteristic speed is the average interface velocity v , plays a central role. We propose a new model for v in terms of the volume fraction and uid velocities, which can be interpreted as a constitutive law for two-uid mixing. In t...

This paper addresses the problem of cache consistency in a client-server database environment. We assume the server provides shared database access for multiple client workstations and that client workstations may cache a portion of the database. Our primary goal is to investigate techniques to maintain the consistency of the client cache and to improve server throughput. We propose a new cache...

We present a dynamical field theory for directed randomly branched polymers and in particular their collapse transition. We develop a phenomenological model in the form of a stochastic response functional that allows us to address several interesting problems such as the scaling behavior of the swollen phase and the collapse transition. For the swollen phase, we find that by choosing model para...
