When properly modified, the MapCHECK response becomes isotropic. It can then be used for patient-specific QA measurements for IMRT treatments delivered with step-and-shoot and rotational techniques such as helical Tomotherapy and RapidArc.

OSLDs can be successfully used for HDR in vivo dosimetry. However, for the measurements to be meaningful one must account for the angular dependence, volume-averaging, and the greater sensitivity to Ir-192 gamma rays than to 6 MV x-rays if 6 MV x-rays were used for OSLD calibration. The limitations of the treatment planning algorithm must be understood, especially for surface dose measurements. Use of in vivo dosimetry for HDR brachytherapy treatments is feasible and has the potential to detect and prevent gross errors. In vivo HDR brachytherapy should be included as part of the QA for a HDR brachytherapy program.

The data compiled in this study on the range of motion in the hip and ankle joint of the Indian population will be useful in the evaluation of patients with disorders of these joints, especially in the Indian and Asian population.

The synthesis and characterization of some transition metal cis-3,7-dimethyl-2,6-octadiensemicarbazone (CDOSC) complexes are reported. The ligand CDOSC yields: [ML 2 Cl 2 ] and [ML 2 Cl 2 ] Cl type complexes, where M=Cr III , Mn II , Fe III , Co II , Ni II , Cu II , Zn II , Cd II and Hg II , L=CDOSC. Structures of the complexes were determined using elemental analysis, molar conductivity, magnetic measurements, i.r. and electronic, as well as n.m.r spectra. CDOSC acts as a bidentate ligand in all the complexes. All the newly synthesized metal complexes, as well as the ligand, were screened for their antibacterial activity. All the complexes exhibit strong inhibitory action against Gram (+) bacteria Staphylococcus aureus and Gram ()) bacteria Escherichia coli. The antibacterial activities of the complexes are stronger than those of the ligand CDOSC itself.
