Measurement of Vector Hysteretic Property of Silicon Steel Sheets at Liquid Nitrogen Temperature

tom R. 87, nr 9b

111-114

This article reports vector magnetic properties of non-oriented silicon steel sheets at the liquid nitrogen temperature of 77 K. The amplitude of magnetic field decreases at 77 K under alternating and rotational flux conditions when B is large. The iron loss increases at 77 K because of the increase in eddy-current loss due to the increase in electrical conductivity.

W artykule przedstawiono badania blachy elektrotechnicznej niezorientowanej w temperaturze ciekłego azotu 77 K. Straty mocy w tej temperaturze wzrastają na skutek wzrostu prądów wirowych spowodowanego zwiększeniem przewodności elektrycznej.

The adaptation and immunogenisity of Cryptosporidium parvum isolated from Siberian chipmunks (SC1 strain) in immunocompetent (ICR) mice were examined. The oocysts were received to the severe combined immunodeficiency (SCID) mice by repeated passage. The oocysts collected from the 18th SCID mice were inoculated to 5 ICR mice. The mice began to shed oocysts from 6 days after inoculation, the patency was 5 days, and the maximum oocysts per gram of feces (OPG) value was 104. The maximum of OPG value was gradually increased by successive passage, and finally that in the 22nd mice reached 106 (patency: 11 days). It is considered that these results indicate completion of their adaptation to ICR mice. To examine the immunogenicity of C. parvum to ICR mice, 8 groups of 5 mice each were inoculated with 1.3 × 106 oocysts of SC1 strain, which were collected after adaptation to SCID mice. All groups shed oocysts from 6th day, and their patency was from 8 to 12 days. On the 21st day after the primary infection, these mice were challenged with 1.3 × 106 oocysts. No oocysts shed from any groups, although 2 control groups shed oocysts from the 6th day, and their OPG values were more than 106. These results suggest that this strain has strong immunogenicity against ICR mice. Therefore, the immunological healthy mice were considered a useful experimental model to investigate immunological and drug treatments in the strain of C. parvum.

The study of bio-inspired robot motion control system

Robots and robotics technologies are expected as new tools for inspection and manipulation. The dynamics of robot always are changed by environment and robot of state in mission. Therefore, an adaptation system, which is able to switch controller due to environment and robot of state, is needed. Meanwhile, animals are able to go through several environments and adapt several own states. The adaptation system is realized Central Pattern Generator (CPG). CPG exists in nervous system of animals and generates rhythmical motion pattern. In this paper, a robot motion control system using CPG is proposed and applied to an amphibious multi-link mobile robot.
