This study was to evaluate whether ionizing gamma radiation could be applied to break the dormancy of a potato minituber. The respiration rate of the minitubers was significantly affected by the storage temperature and a low dose gamma radiation. Ionizing radiation of 8 Gy enhanced the respiration rate of the potato tuber stored at for 20 days. The potato tuber subjected to 4 and 8 Gy after 40 days storage at 10 and exhibited higher respiration rates compared to the control (non-irradiated), but not at st. However, the ionizing radiation did not exhibit on significant effect on the respiration rate of the potato tuber stored for 60 days. It was observed that minitubers stored for 20 days had significant response to the storage temperature in terms of the total sugar content the higher the storage temperature, the lower the total sugar content. It was measured that the reducing sugar content was increased under the storage conditions both 5 and for 40 days, but not to . The total sugar contents in the minituber stored for 60 days were similar to those stored for 40 days. The data was discussed on the relationships among the storage duration, temperature and ionizing radiation.

The number of nodes within 1-hop range plays an important role in determination of ad-hoc network performance. The more the number of 1-hop neighbor increases, the more routing traffic is generated. Although there have been several studies on the optimal number of 1-hop neighbor nodes, they had not considered routing overhead. In this study, we derive new optimal number of 1-hop neighbor nodes to maximize network throughput considering routing overhead. Numerical results show that the optimal number of 1-hop neighbor nodes depends on various factors such as the total number of nodes in a network, average node speed and routing algorithm.
