  • Preclinical and safety studies of V-1 Immunitor

    The safety of V-1 Immunitor (V1) has been investigated. L929; BHK; Vero; Caco-2 and CEM-SS cells have not shown cytotoxicity even at 10 mg/ml dose. Ames' mutagenicity and micronucleus genotoxicity tests came out negative at 50 mg and 2000 mg/kg doses in Salmonella and bone marrow of IRC mice. Acute and chronic dosing of V1 to Swiss albino mice and Spague Dawley rats failed to cause any deaths. ...

  • A folded wedge model for determination of true stratigraphic thickness in directional wells

    For exploration and development the geologists and engineers try to know the true stratigraphic thickness (t). The monoclinal and folded bed models are published methods for t calculation. Both models assume parallel beds which can lead to significant deviations. In order to calculate the values of t considering the effects of both folding and stratigraphic variation we propose the 'folded wedge ...
