The performance of the high temperature superconductor (HTS) is progressing rapidly and the enhancement in [J.sub.c] in Bi2223 long wires are achieved. The design study of the magnet by using the latest Dynamically Innovative bismuth-based HTS wire (DI-BSCCO) has shown that the higher magnetic field is produced with almost the same size of the magnet.

The progress on the development of high temperature superconducting magnets using Bi-2223 Ag-sheathed wire is reported. Two types of refrigerator cooled high temperature superconducting magnets, namely, a high magnetic field type and a large bore type, were successfully constructed. The magnets were developed using Bi-2223 silver-sheathed tape wire. Results show that one of the most important benefits of the magnets is their capability of rapid excitation.

Sumitomo Electric, DuPont and Aquafine successfully employed a high temperature superconducting (HTS) magnet system in separating mineral contaminants from kaolin clay. The magnetic separation effort involved the extraction of paramagnetic and ferromagnetic contaminants from five types of kaolin. Results from brightness tests reveal that conventional and HTS magnets generate consistent brightness at 2.0 T.

The powder-in-tube technique was utilized in fabricating silver-sheathed BiPbSrCaCuO 223 superconducting long length wires with a high critical current density of 10(super 4) A/cm2. Considerations involving crystal alignment and connectivity between grains and flux pinning were found to be useful in achieving higher critical current densities. High strength and high amperage wires were also also developed for applications in large scale magnets.

The aborigines of Taiwan represent the indigenous inhabitants of the island at the time of the arrival of the Chinese from the mainland. Three tribes occupied lowland areas while six tribes occupied highland areas. Previous studies indicate malarial selection on the lowland populations. Linguistically the aboriginal Taiwanese are related to the Malayo-Polynesian speaking inhabitants of Indonesia and the Philippines. Though the GM haplotypes are demonstrated to be very useful in the measure of population affinities, the possibility of malarial selection on this locus could affect studies of population affinity. This is a case study to see whether a subdivided insular population under a possible selective load will provide divergent clustering analysis depending on the population sampled. Immunoglobulin allotype (GM and KM) profiles were generated on 167 lowland and 468 highland Taiwan Aborigines from the dine tribes. A highly significant difference was detected between lowland and highland populations adjusted [G.sup.2] = 39.417, 3 df, p [is less than][is less than] 0.001). There were no significant differences in KM*1 frequency by altitude. The Taiwan aboriginal GM frequencies were compared to data from Indonesians, I, Vietnamese, Thai, Malay, Chinese from Taiwan and Okinawan's using principal component analysis (PCA). The Lowland populations plot among the Thai (N, NC) and Malay. In contrast the Highland and Total Taiwan aborigine samples plot with the Indonesian and Vietnamese samples. Thus, depending on the populations of Taiwan Aborigines used, different conclusions would be reached. The Highland population supports the published linguistic ties, however, the lowland population do not support the linguistic relationship with Indonesian populations but are more closely related to Thai and Malays or reflect a similar selection history.
