We study the probability distribution of residence time, T , of the sand grains in the one dimensional abelian sandpile model on a lattice of L sites, for T << L and T >> L. The distribution function decays as exp(−L L2 ). We numerically calculate the coefficient KL for the value of L upto 150 . Interestingly the distribution function has a scaling form 1 La f( T Lb ) with a 6= b for large L. K...

Channel holding time is of primary importance in teletraffic analysis of PCS networks. This quantity depends on user’s mobility which can be characterized by the cell residence time. In this paper we show that when the cell residence time is not exponentially distributed, the channel holding time is not exponentially distributed either, a fact also confirmed by available field data. In order to...

We present an analytic model for the performance evaluation of hierarchical cellular systems, which can provide multiple routes for calls through overflow from one cell layer to another. Our model allows the case where both the call time and the cell residence time are generally distributed. Based on the characterization of the call time by a hyper-Erlang distribution, the Laplace transform of ...

Heat transfer coefficients in a continuous oscillatory baffled crystallizer (COBC) with nominal internal diameter of 15 mm have been determined as function flow and conditions typically used under processing conditions. Residence time distribution measurements show near-plug high Peclet numbers on the order 100–1000 s, although there was significant oscillation damping longer COBC setups. Very ...

Fibroblast growth factor-1 (FGF-1) is an angiogenic factor with therapeutic potential for the treatment of ischemic disease. FGF-1 has low intrinsic thermostability and is characteristically formulated with heparin as a stabilizing agent. Heparin, however, adds a number of undesirable properties that negatively impact safety and cost. Mutations that increase the thermostability of FGF-1 may obv...

In-feed Medication has been used for a long time to prevent coccidiosis, a worldwide protozoal disease in rabbits. Florfenicol (FFC) has been widely used in veterinary clinics for bacterial diseases treatment. Therefore, the use of combinations of coccidiostats with FFC in rabbits is common. In the present study, we aimed to evaluate the effect of three coccidiostats, sulfaquinoxaline (SUL), ro...
