“…The composition and geometrical data belonging to liver tissue have been given to MCNP4C as input data [13,14]. In the simulation, neutron slowing down has been taken into account as well [15]. The input data to MCNP4C code are the radius of polyethylene sphere (20 cm), the thickness of cadmium layer (100 μm), radius and thickness of graphite reflector (25 cm and 5 mm, resp.…”

In this investigation, neutron capture therapy (NCT) through high energy neutrons using Monte Carlo method has been studied. In this study a new method of NCT for a sample liver phantom has been defined, and interaction of 12 MeV neutrons with a multilayer spherical phantom is considered. In order to reach the desirable energy range of neutrons in accord with required energy in absence of eligible clinical neutron source for NCT, this model of phantom might be utilized. The neutron flux and the deposited dose in the all components and different layers of the mentioned phantom are computed by Monte Carlo simulation. The results of Monte Carlo method are compared with analytical method results so that by using a computer program in Turbo-Pascal programming, the deposited dose in the liver phantom has been computed.

This paper presents a review of all the aspects of slowing down phenomena in which stochastic considerations of the process need to be taken into account. The cases both with and without absorption are treated. A consistent treatment is given of the energy distribution functions, the moments of collisions to slow down past a certain energy, the speed of neutrons and the slowing down time, with explicit expressions for the expectation and variance in all cases. Besides a compact and uniform derivation of known results, some new results are also presented.

The stability of a two-phase interface is a crucial occurrence that involves the design of many engineering applications. It correlates the spatial and droplet size-distributions of many fluid spraying applications and has a great effect on the estimations of the critical heat flux of systems that involves phase change or evaporation. However, the existing hydrodynamic models are only able to predict the stability of a plane fluid sheet, surrounded by an infinite pool of liquid. The case of a thin sheet of liquid surrounding a vapor sheet and enclosed between two walls has not been studied yet. The present paper solves this problem using a linearized stability analysis. Velocity potentials satisfying these conditions are introduced and a complete analysis is presented.
