Influence of gamma irradiation to the magneto-impedance ratio of the electrodeposited [NiFe/Cu]4 multilayer on meander-shape PCB substrate has been studied. The magneto-impedance ratios were measured for both un-irradiated and irradiated by gamma radiation of Co-60 with a total dose of 40 Gy. The morphological structure were done by using scanning electron microscopy (SEM). The decrease in grain size of the samples after Gamma irradiated is observed. The magnetic property modifies as consequence of the change in the microstructure samples. Within result, the magneto-impedance ratio decreases around 34.9% for irradiated sample.

Anther Culture Response

This study examined the anther culture response of wheat to different doses of gamma radiation, and the interaction of radiation dose with a cold pretreatment of ears stored prior to culturing. The cultivars Grebe and Kite were chosen on the basis of their anther culture response, Grebe being highly responsive and Kite being non-responsive. Spikes of the two cultivars were exposed to various levels of gamma radiation (60Co source) ranging from 0 to 10 Gy (0.53 Gy min-1) before anthers were plated on an agarose-solidified medium. For Grebe, doses of 1, 3 and 5 Gy resulted in more embryoids, higher green plant regeneration, and a greater number of spontaneously doubled haploids (DH), than in the non-irradiated control. The response in Kite was similar but less pronounced. The higher doses of radiation (7 and 10 Gy), however, were detrimental in both cultivars and at 10 Gy no embryoids or regenerants were produced. Anthers subjected to a cold pretreatment prior to irradiation responded significantly less than those cultured fresh. This study indicated that low-dose gamma irradiation of fresh explants can significantly improve regeneration from anther cultures in wheat and may stimulate a low frequency of regeneration in an otherwise non-responsive cultivar.

The lateral line organs of the sea eel consist of canal and pit organs which are different in function. The former is a low frequency vibration detector whereas the latter functions as an ion receptor as well as a mechano receptor.The fine structure of the sensory epithelia of both organs were studied by means of ordinary transmission electron microscope, high voltage electron microscope and of surface scanning electron microscope.The sensory cells of the canal organ are polarized in front-caudal direction and those of the pit organ are polarized in dorso-ventral direction. The sensory epithelia of both organs have thinner surface coats compared to the surrounding ordinary epithelial cells, which have very thick fuzzy coatings on the apical surface.
