X-ray spectrometry applied for determination of linear attenuation coefficient of polymer-based samples as radiologically tissue-equivalent materials

In this work we obtained experimental linear attenuation coefficients of polymer-based samples at diagnostic imaging energy range (15-150 keV) for eleven formulations candidates for tissue-equivalent materials (TEMs). TEMs is any material that simulates a human body part or human tissue in its interaction with radiation. In diagnostic radiology,  the maximum difference between the linear attenuation coefficient of the TEMs and the target material should be no more than 5% in the energy range of interest. A polienergetic narrow beam was obtained using a tungsten target x-ray tube and CdTe detector. The densities of the samples were determined and compared with reference materials obtaining a maximum difference of 17%. The comparisons between the  linear attenuation coefficient of the formulations and the respective reference materials for which they were initially designed, has demonstrated good correspondence over a wide energy range. Energy ranges in which the developed samples simulate other human tissues in addition to those initially considered were found, taken into account the criterion that the maximum difference between the linear attenuation coefficients does not exceed 5% is met. The results emphasize the possibility of production and characterization of TEMs to be used in the construction of imaging and dosimetry phantoms

Strategic and institutional effects on foreign IPO performance : Examining the impact of country of origin, corporate governance, and host country effects

By integrating signaling research with an institutional perspective we examine how country of origin, corporate governance, and host market effects impact foreign IPO performance. Using a sample of 202 foreign IPOs listed in the U.S. or U.K in 2002-2007 results indicate both the legal environment surrounding these organizations in their countries of origin and board independence impact the success of foreign firms at IPO. However, the institutional environment of the chosen IPO market impacts the salience of country and corporate governance signals for foreign IPO firms suggesting a more contextualized framework of IPO valuation is necessary
