A simple semi-empirical model for the calculation of the detonation pressure and velocity for CHNO explosives has been developed, which is based on experimental values of the detonation parameters. Model uses the Avakyan method for the determination of the chemical composition of the detonation products, and is applicable over a wide range of densities. Compared with the well-known Kamlet method and the numerical model of detonation based on the Becker-Kistiakowsky-Wilson Equation of state (BKW EOS), the calculated values from the proposed model have significantly better accuracy. © 2012 Copyright (CC) SCS.

Purpose: The aim of this study was to evaluate the clinical reliability of the immunoscintigraphy with iodinated monoclonal antibodies for the detection of metastases and recurrences of colon carcinomas. Methods: A total of 45 patients with colon carcinoma was investigated with gamma camera, after intravenous application of iodinated monoclonal antibodies. Results: The sensitivity of the method was 90%, specificity 86%, positive predictive value 93%, negative predictive value 80% and accuracy 87%. There was statistically significant relationship between immunoscintigraphic and ultrasonographic (US) findings (p=0.005). Also, there was significant relationship between immunoscintigraphy and Dukes stage (p=0.019). Tumor marker levels were not significantly correlated with immunoscintigraphic findings (p>0.05). Significant difference was noted in patients with positive findings for malignancy on US and immunoscintigraphic findings (p=0.006), i.e. patients with positive findings for malignancy had more frequently immunoscintigraphic findings of malignancy. Correlation with other diagnostic procedures (rectoscopy, colonoscopy, CT) did not show significant correlations. Conclusion: We conclude that immunoscintigraphy can be helpful in the detection of metastases and recurrences of colon carcinomas. © 2012 Zerbinis Medical Publications. Source
