Background: Neutron contamination is produced in electron beams of linac when tooth or dental materials are located in the path of beam. Objective: This study aims to determine the neutron dose contamination from different dental restoration materials in electron mode of a linac. Material and Methods: In this experimental study, the neutron dose contamination was calculated in the p...

In contrast, when ν → 0, the posterior odds are just equation (5) with ν replaced by 0. This means that gene-specific Ws are so different such that moderation is not able to move these gene-specific W at all. Thus, the degree of moderation reflects how similar these gene-specific within group sums of squares are. The more similar they are, the greater degree of moderation our proposed statistic...

The design of complex social systems, such as online communities, requires the consideration of many parameters, a practice at odds with social science research that focuses on the effects of a small set of variables. In this paper, we examine three design decisions—topical breadth, message volume, and discussion moderation—and the trade-offs involved in making these decision. We show how synth...

Criticality safety reanalyzes of the NPP Krško spent fuel pool has been performed. Limiting criticality cases at optimal moderation conditions are calculated using different SCALE code versions (SCALE-4.4a, SCALE-5.1 and SCALE-6.1) with 44-group ENDF/B-V 238-group ENDF/B-VII.0 derived cross section libraries. Relative small discrepancies observed. Additional verification is provided SERPENT MCN...

In this article, we advocate a new approach in theory development by translating and synthesizing insights from multiple social science theories in an agent-based model to understand challenges in building online communities. To demonstrate the utility of this approach, we use it to examine the effects of three types of discussion moderation in conversation-based communities: no moderation, in ...

Introduction: The Monte Carlo simulation is used to enhance reliability in the experiments related to nuclear instruments. in addition, that is used to calculate the different components of the neutron and gamma ray fluxes in boron neutron capture therapy(BNCT) and neutron capture (NCT)applications. BNCT is one of the methods in radiotherapy, that is used the neutron beam for ki...

beryllium chemical combination has a considerable effect on the design and fabrication of the241am9be neutron source. in this investigation the beryllium combinations were studied as a generator ofneutrons with various mass percentage, and the neutron yields were also calculated using the results of thealice and srim codes calculations per unit incident charge. the neutron yields of beryllium ...

Background: In high-intensity, mixed and pulsed neutron fields the use of spectrometers or area monitors with active detectors is useless in these conditions neutron measuring devices must have a passive detector. Here a passive neutron area monitor with CR39 track detector was designed and the response was calculated. Materials and Methods: The response of a passive neutron area monitor with C...
