Significant Difference

The research was carried out to assess the technology of laserpuncture for estrous synchronization of ewes in different phase reproduction. The results of the research showed that the treatment of laserpuncture at 17 reproduction accupoints during the luteal phase and at anytime perform 100% and 95% of oestrous, respectively. It indicates that the laserpunktur technology is capable to generates a synchronization of oestrus in ewes. There was no significant difference of oestrus response which observed from both of treatments at luteal phase or at any time. It is concluded that the laserpuncture technology is one of alternative technology for estrous synchronization beside hormone treatment.

Alloy Plating

Composite plating Ni-P-PTFE- nano- Al2O3was made by adding nano-scaled Al2O3and PTFE into chemical plating Ni-P alloy plating solution. The influences of the plating material’s hardness, abrasion and antifriction property caused by the additive amount of nano- Al2O3and PTFE were studied in the paper. The results indicate that the composite plating’s hardness, wear resistance and antifriction can be greatly improved by adding nano- Al2O3and PTFE into it.

Magnetocaloric refrigeration is increasingly being explored as an alternative technology for cooling. This paper presents the design and fabrication of a micromachined magnetocaloric cooler. The cooler consists of fluidic microchannels (in a Si wafer), diffused temperature sensors, and a Gd5(Si2Ge2) magnetocaloric refrigeration element. A magnetic field of 1.5 T is applied using an electromagnet to change the entropy of the magnetocaloric element for different ambient temperature conditions ranging from 258 K to 280 K, and the results are discussed. The tests show a maximum temperature change of 7 K on the magnetocaloric element at 258 K. The experimental results co-relate well with the entropy change of the material.
