An Evaluation of the Hazard Prediction and Assessment Capability (HPAC) Software\u27s Ability to Model the Chornobyl Accident

A parameter study was conducted for a space nuclear reactor radiation shield. The focus of this research was to explore alternatives to current radiation shield designs to reduce the mass while maintaining the same shielding performance. MCNP4C was used to determine the parameters necessary to build an optimum shield. A design known as the split scatter shield offered some potential for reductions in shield mass. In theory, less material is required for this type of shield, which uses thin shield sections to scatter radiation away from the dose plane. The parameters for this shield design are the shield geometry, number of shield sections, and material selection. Split scatter shielding offers a potential for reducing the shield mass by allowing the gamma shield material to be moved closer to the source plane. Further research needs to be conducted on this shielding technique, however, to isolate optimum shield values. Once these optima have been identified, a split shield can be developed and compared to the original shield performance. Finally, an energy deposition study indicates that the split scatter shield will absorb less energy than the unit shield, implying that there may be less thermal stress on a scatter shield

Effects of radiation on immune system and latent virus reactivation

The purpose of this NCRP commentary is to provide the current state of knowledge on the effects of ionizing radiation on the immune system and on latent herpes virus reactivation to the scientific community and government agencies. Its purpose is to better understand radiation-induced latent virus reactivation, which is possibly an underestimated consequence of ionizing radiation exposure. This activity should involve the radiation research community (academia, industry and regulatory agencies) and government agencies (NASA, DOD, CDC)

Prolégomènes à toute appréciation critique de CANDIDE

This text describes the CANDIDE model from three critical points of view. First, it presents the structure of the model with the aid of a table of "supersectors" and a flow chart. The discussion of the linkages between these supersectors brings out the general equilibrium character of the model.The center section of the paper deals with the theoretical foundations of the behavioural equations. A statement of the equation specification in each sector of the model is followed by a brief evaluation. The authors confess to an eclectic attitude and stress the practical difficulties of making stylized theories bring order in variegated facts. Exogenous influences on the model are discussed as well.The same eclectic approach is evident in the third part of the text which treats of estimation and validation. A variety of tests and checks—some novel ones included—are applied in the process of developing the model. The authors conclude with the observation that recent tumultuous developments in the economy raise fundamental questions about the validity and usefulness of models like CANDIDE

A Social Identity Perspective of Personality Differences between Fan and Non-Fan Identities

In three studies of fan communities we examined differences in the Big Five personality traits between fans’ personal and fan identities. In all three studies, self-identified furries completed a measure of the Big Five personality traits for both their personal and furry identity. In Study 1, furries were found to rate all five dimensions higher when referring to their furry (vs. personal) identity. In Study 2 we replicated these results and further found that the effect was not limited to furries: sport fans also reported different personality ratings when referring to their fan or personal identity. In Study 3, we again replicated the results while testing predictors of personality differences between salient identities. A path model showed that felt connection to one’s fandom identity predicted greater frequency of fandom identity salience, which, in turn, predicted greater personality disparity between identities. Taken together, the results suggest the role of the social identity perspective in explaining inconsistencies in personality
