We examined the dose from mTc contained in syringes and shielded vials to assess in detail the dose burdens in a central pharmacy. Methods: Absorbed-dose rates at the end of the plunger of a shielded syringe, when mTc is contained either in the syringe or in a shielded vial from which the activity would be drawn, were measured with CaF2 dosimeters. The dose rates also were calculated with a Mon...
UNLABELLED We examined the dose from 99mTc contained in syringes and shielded vials to assess in detail the dose burdens in a central pharmacy. METHODS Absorbed-dose rates at the end of the plunger of a shielded syringe, when 99mTc is contained either in the syringe or in a shielded vial from which the activity would be drawn, were measured with CaF2 dosimeters. The dose rates also were calcu...
OBJECTIVE To evaluate the cytotoxicity of poly(ethylene glycol)-block-poly(D,L-lactic acid) (PEG-PDLLA) nanovesicles loaded with doxorubicin (DOX) and the photosensitizer hematoporphyrin monomethyl ether (HMME) on human hepatocellular carcinoma HepG2 cells and to investigate potential apoptotic mechanisms. METHODS PEG-PDLLA nanovesicles were simultaneously loaded with DOX and HMME (PEG-PDLLA-...
A new analytical approach is used in the design of disc-like gradient coils suitable for magnet geometries with main field direction perpendicular to the surface of the disc. An inverse procedure is used to optimize the coil's characteristics, subject to the restrictions imposed by the desired field behavior over a certain set of constraint points inside a predetermined imaging volume. Excellen...
In this work, the development and validation of a methodology for robotic welding with covered electrodes (SMAW) using a variation of the tool center point (TCP) model is shown. The covered electrode becomes part of the kinematic model of the robot as an additional prismatic joint, whose movement is determined by the electrode consumption or melting rate. This allows programming the trajectory ...
