Field Applications of Ultra High Frequency Techniques for Defect Detection in GIS.

The reliable and stable operation of power apparatus is important for the development of GIS. It is important to utilize condition monitoring technologies and anticipate possible failures in advance. Many papers have been published about the partial discharge detection with UHF or X-ray in laboratory, but seldom in field application.

[The effect on apoptosis in anterior pituitary induced by cadmium chloride and its relations with caspase-9 pathway].

Objective: To study the effects of cadmium chloride in anterior pituitary and the relation between apoptosis and expression of procaspase-9 mRNA.

Methods: In vivo studies:40 SD male rats were randomly distributed into four groups which were administered with CdCl2 at different doses by gavage for 6 weeks;

In Vitro Studies: the rats' anterior pituitary cells were primarily cultured for 120 hours, then treated with CdCl2 at the dose of 0, 1.56, 3.
