Physical properties of maxillofacial elastomers under conditions of accelerated aging.
The stability of the physical properties of various commercially available maxillofacial prosthetic materials was evaluated with the use of an accelerated aging chamber. The tensile strength, maximum percent elongation, shear strength, tear energy, and Shore A hardness were determined before and after accelerated aging. Results indicate that silicone 44210, a RTV rubber, is a promising elastome...
متن کاملQuantitative trait loci associated with longevity of lettuce seeds under conventional and controlled deterioration storage conditions
Lettuce (Lactuca sativa L.) seeds have poor shelf life and exhibit thermoinhibition (fail to germinate) above ∼25°C. Seed priming (controlled hydration followed by drying) alleviates thermoinhibition by increasing the maximum germination temperature, but reduces lettuce seed longevity. Controlled deterioration (CD) or accelerated ageing storage conditions (i.e. elevated temperature and relative...
متن کاملAbsence of Lipid Oxidation during Accelerated Aging of Soybean Seeds.
When seeds of soybean were subjected to accelerated aging, the amount of total lipid which was extracted from the whole seed increased with "age," whereas the extractable phospholipid decreased slightly. This small decline primarily reflected changes in the amounts of phosphatidylcholine and phosphatidylethanolamine. The levels of unsaturated fatty acids in the whole seed and in the seed axis s...
متن کاملEffect of Priming on Germination and Enzyme Activity of Achillea vermicularis Seeds after Naturally and Accelerated Aging
Ageing induces seed deterioration expressed as the loss of seed vigor and/or viability. Priming treatment, which consists in soaking of seeds in a solution of low water potential, has been shown to reinvigorate aged seeds. An experiment was conducted to evaluate the effects of naturally and accelerated aging on seed germination traits and enzyme activities (proxidase, catalase and superoxid dis...
متن کاملInfluence of storage conditions on quality and viability of high and low oleic sunflower seeds
Storage conditions of oil seeds before industrial extraction might influence the quality of the crude oil. The aim of present study was to clarify the storage able potency of high and low oleic cultivars of sunflower based on oil and fatty acid changes of seeds and their viability. The seed samples of four sunflower cultivars (two high oleic and two low oleic) were stored in three different tem...
