A very high energy -ray signal has been detected at the 5.5 level from H1426+428, an X-ray–selected BL Lacertae object at a redshift of 0.129. The object was monitored from 1995 to 1998 with theWhipple 10 m imaging atmospheric Cerenkov telescope as part of a general blazar survey; the results of these observations, although not statistically significant,… (More)
Time domain terahertz (TD-THz) non destructive evaluation (NDE) imaging is used to two-dimensionally map the thickness of yttria stabilized zirconia (YSZ) thermal barrier coatings (TBC) on aircraft engine turbine blades. Indications of thermal degradation can be seen. The method is non-contact, rapid, and requires no special preparation of the blade.
In this investigation an effort has been made to find the effect of water depth on distillate production and to establish thermodynamic relations among the operating parameters to study their effects on still performance. In this work water is heated in a water bath and the top cover is replaced with a glass to act as condensing surface. Water is fed into… (More)
