In this research we conducted a sensitivity experimental study where we explored the dependency of the shear strain on the seismic properties of bearings, namely lead rubber bearing (LRB) and super high damping rubber bearing (SHDR). The factors studied were vertical pressure, temperature, shear modulus of the inner rubber (G value), loading frequency, and loading sequence. Six specimens were adopted, i.e., three LRBs and three SHDR bearings. A series of test plans were designed. The seismic characteristics of the bearings were captured through a cyclic loading test, which included post-yield stiffness, characteristic strength, area of a single cycle of the hysteretic loop, equivalent stiffness, and equivalent damping ratio. A whole analysis of variances was then conducted. At the same time, to explore certain phenomena caused by the factors, an extended discussion was carried out. Test results showed that the temperature is the most dominant feature, whereas the G value is the least contributing factor, with the effect of the loading frequency and the loading sequence found between these two. The increment of the post-yielded stiffness for LRB from 100% to 25% is a significant reduction from a low temperature to high one. The slope of the characteristic strength versus the shear strain for LRB under high temperature is larger than the one under low temperature.

The chromosome number of eight species and varieties of Asclepias (A. syriaca, A. incarnata and variety pulchra and forma albiflora, A. Sullivantii, A. tuberosa, A. curassavica, A. speciosa) was found to be 2n = 22.Various interspecific pollinations were attempted without success. A cross of A. incarnata with forma albiflora was successful.Possible natural hybrids between A. syriaca and A. speciosa and between A. incarnata and var. pulchra and forma albiflora are described. Two unusual chimaeral plants of A. incarnata that produced several stems of forma albiflora are described.
