Temperature Measurement System

In the accelerated ageingtest of fuses, manual measurement was used to collect the temperature of fuse.By this testing method, the errors introduced by human were inevitable. In thispaper, an automatic temperature measuring type accelerated ageing test systemfor fuses was developed. So, the errors introduced by human were overcome.

The Relationship

An accelerated ageing test equipment with the pressure transducer and digital indicator is designed in the light of the features that the rubber seal used in aviation industry always stand compression stress. This equipment can do real-time monitor on the compression stress of rubber materials in accelerated ageing test. The stress measurement range is 0～980 N, and the temperature fluctuation range is 0～200°C. With this equipment, the compression stress relaxation and stress permanent set can be tested and the relationship between them in 100°C can be found.

The objective of this work was to establish the temperature and the period of exposure needed to perform the traditional accelerated ageing test with saturated NaCl salt solution on chickpea seeds. Eight seed lots from two cultivars, including four seeds each, were subjected to germination and vigour tests for initial characterization. Following the methodology of the traditional accelerated ageing test. The seeds were placed on stainless steel screens in boxes with 40 mL deionized water. They were kept at 41 and 45º Celsius for 24 and 48 hours. Furthermore, the accelerated ageing test using [40 g of NaCl in 100 mL of water, thus providing 76% of relative humidity in air] NaCl (salt) solution in place of the deionized water was performed. Aged seeds were sowed in germination paper and kept in a germination chamber at 41º and 45º Celsius. The evaluations were performed five and eight days after sowing. The statistical analysis was performed with a completely randomized design and four replications. The traditional ageing of both cultivars showed a water content higher than the tolerated limits at 48 hour period and 41 and 45 °C. In the saturated saline test, the cultivar BRS Aleppo produced consistent results at temperatures 45 °C for 24 h. The cultivar Cícero showed a low correlation with the initial characterization as the results of accelerated ageing. Thus, for ‘BRS Aleppo’, the recommended accelerated ageing methodology was application of saturated saline solution, when seed exposed to 41 °C for 24 hours with germination evaluation at the first count date. For 'Cicero', satisfactory results were not obtained, and new studies are required to establish a methodology.

The purpose of this study was to determine changes of lipoxygenase activities, contents of antioxidants (tocopherol ?, ?-carotene and chlorophyll) fatty acids and soluble proteins, as well as, vigor in accelerated aged soybean seeds. The following soybean cultivars were used in the study: Williams 82, Goyou Kurakake and L93-7290. Subsequent to the accelerated ageing test (AAT), 23% of seeds of the cultivar Goyou Kurakake retained normal germination, while grain of the two remaining cultivars L93-7290 and Williams 82, completely lost germination ability. According to our results, the seeds of the cultivar Goyou Kurakake (the absence of lipoxygenases 2) is characterized by a significantly higher content of all observed antioxidants (tocopherol ? 2.7 mg 100g-1, ?-carotene 6.1 ?g g-1 chlorophyll 4.9 ?g g-1). The contents of (?-carotene and chlorophyll decreased after AAT in the seed of the cultivar Goyou Kurakake by 42.8% and 60.5%, respectively, while the content of tocopherol a remained the same. Furthermore, the tocopherol a content was not changed after AAT neither in the cultivar L93-7290 nor in the cultivar Williams 82. The content of ?-carotene after AAT remained the same in seeds of the cultivar Williams 82 while it decreased by 7.7% in the cultivar L93-7290. Since changes of the fatty acids content were not pronounced in the cultivar Goyou Kurakake after AAT it can be concluded that the antioxidative system had a crucial role in seeds protection against lipid peroxidation.
