the ionization effects of charged particles produced in neutron interactions for boron neutroncapture therapy are considered here using srim monte carlo code. the estimated values of these effects ina plexiglas acrylic phantom are shown to agree well with the available experimental values in high boronconcentration areas. as expected, the ionization effects from lithium and alpha particles are ...

discrete element method (dem) is extensively used for mathematical modeling and simulating the behavior of discrete discs and discrete spheres in two and three dimensional space, respectively. prediction of particles flow regime, power draw and kinetic energy for a laboratory or an industrial mill is possible by dem simulation. in this article, a new approach was used to assess the main paramet...

IIlite clay particles with adsorbed 137Cs were added as a submillimeter layer to the surface of stir-clay sediments contained in rectangular Plexiglas ceils stored in a temperature-regulated aquarium, in order to tmee the effect of the ollgochaete, Tubifex tubifex, and the amphipod, Pontoporeia hoyi, on mass redistribution near the sedimentwater interface. A well-collimated NaI gamma detector s...

OBJECTIVE(S) The hippocampus has been implicated in pathophysiology of schizophrenia. Prenatal stress is a contributing risk factor for a wide variety of neuropsychiatric diseases including schizophrenia. This study examined long-term effects of prenatal restraint stress on the stereological parameters in the Cornu Ammonis (CA) of adult male rats as an animal model of schizophrenia. MATERIALS...

background this study demonstrates the removal efficiency of phenol from aqueous solutions by electrocoagulation process using aluminum electrodes and also investigates solution chemistry and polymeric natural organic matters on removal efficiency objectives: the main aim of this work was to focus on the removal of phenol by electrocoagulation process using aluminum electrodes. materials and me...

Introduction: Dual energy x-ray absorptiometry (DEXA) is one of the most widely used methods measuring periprosthetic bone mineral density (BMD). Several reports have presented the precision of DEXA when used at the hip, whereas similar reports on factors influencing the precision at the knee are sparse. There are two noticeable aspects when measuring BMD at the knee. First, no software specifi...

This research evaluated the efficiency of combined anaerobic-aerobic processes for the treatment of slaughterhouse wastewater. The anaerobic reactor consists of a 3.95 L Plexiglas column with 60 mm diameter and 140 cm height. The cylindrical particles of polyvinyl chloride with 2 mm diameter and 1250 kg m-3 density packed to 60 cm of column were used as biomass saving material. The d...

In the present work the results of the known investigation of the influence of combined static (40 microT) and alternating (amplitude of 40 nT) parallel magnetic fields on the current through the aqueous solution of glutamic acid, were successfully replicated. Fourteen experiments were carried out by the application of the combined magnetic fields to the solution placed into a Plexiglas reactio...
