To compare the presence in levels of antiovarian antibodies (AOAb) in the pre- and postovulatory stage from serum of infertile patients undergoing intrauterine insemination (IUI) or in vitrofertilization (IVF) with outcome of the procedures. Serum from 36 women undergoing IUI, 36 women undergoing IVF and 25 fertile, healthy controls were assayed for the(More)
An absolute methodology has been developed for quantification of misalignment of an ultrasonic transducer using a corner-cube retroreflector. The amplitude based and the time of flight (TOF) based C-scans of the reflector are obtained for various misalignments of the transducer. At zero degree orientation of the transducer, the vertical positions of the(More)
The paper presentsan ultrasonic guided wave methodology for inspection of a fillet joint with a bend.Owing to the complex shape of the geometry, it is not amenable for conventional techniques. The methodology developed utilizes through-transmission ultrasonic testing. Two 90Δ angle beam (surface wave) ultrasonic transducers of central frequency 2.25 MHz,(More)
The brain requires constant oxygen supply to perform its biological functions essential for survival. Because of low oxygen capacity and poor oxygen diffusibility of water, many fish species have evolved various adaptive mechanisms to cope with depleted oxygen. Endothelial cells (EC) are the primary components responsible for controlled environment of(More)
