During 1990 we surveyed the southern sky using a multi-beam receiver at frequencies of 4850 and 843 MHz. The half-power beamwidths were 4 and 25 arcmin respectively. The finished surveys cover the declination range between +10 and −90 degrees declination, essentially complete in right ascension, an area of 7.30 steradians. Preliminary analysis of the 4850 MHz data indicates that we will achieve a five sigma flux density limit of about 30 mJy. We estimate that we will find between 80 000 and 90 000 new sources above this limit. This is a revised version of the paper presented at the Regional Meeting by the first four authors; the surveys now have been completed.
A novel deposition process has been developed for manufacturing of high quality rare-earth doped glass films with complex composition. This process, Laser Reactive Deposition (LRDTM), comprises photothermal laser pyrolysis using an aerosol feedstock coupled with deposition of the resulting nanoparticle product onto Si substrates with our without an underlying glass film. This paper describes this novel process as well as the structure, properties and performance of the Erdoped, multicomponent silicate glass films produced to date with this process.
We conducted a pilot group intervention for negative symptoms, particularly targeting avolition/apathy. A baseline control design was used. Six patients were recruited, and four completed the group. The main inclusion criteria were clinically significant negative symptoms, plus associated distress and concern. The group involved 16 sessions, which were cognitive behavioural in approach. The main outcome measures were the Scale for the Assessment of Negative Symptoms, and the Subject Experience of Negative Symptoms Scale. Patients showed a reduction in avolition/apathy, and two patients reported reduced distress. These preliminary results suggest that group CBT is a possible intervention for negative symptoms.
