Aging of asphalt pavements typically occurs through oxidation the and evaporation lighter maltenes from binder. The main objective this study is to evaluate influence aging on performance paving materials.nAsphalt concrete mixtures, were prepared, subjected short term (STA) procedure which involved heating loose mixtures in an oven for two period (4 8) hours at a temperature 135 o C. Then it wa...
Background : Due to the decrease in fertility rate and the increase in the number of aging people, middle-aged adults are more important than ever as an important source for keeping elderly people in families. Understanding and insight into aging care by middle-aged people is necessary to promote health in middle age and old age. The present study was conducted with the aim of understanding the...
Circuit aging refers to the deterioration of circuit performance over time. All portions of a System-on-Chip (SoC), analog, digital logic, and memory, are affected by aging. In this survey, three main aging mechanisms will be introduced: Bias Temperature Instability(BTI), Time Dependent Dielectirc Breakdown(TDDB), Hot Carrier Injection(HCI). This survey also introduces a concept of circuit fail...
Unfavorable storage conditions, especially relatively high environment humidity and high storage temperature greatly affect the quality of corn seeds. The effects of temperature, environment moisture and length of storage on six maize hybrids were examined. For the purpose of investigating germination traits, total soluble proteins, leakage electrolytes and the activity of antioxidant enzymes i...
