Although resprouting plays an important role in facilitating persistence of damaged seedlings, the functional attributes of cotyledons and taproots during resprouting of 1-year oak seedlings are not well explored. In this study, cotyledons were removed from Quercus mongolica seedlings to explore resprouting in response to simulated disturbance as a function of shoot clipping, and to examine the...

Direct injection diesel engines are in service for both heavy duty vehicles, light duty vehicles not only in the fields of agriculture and transport sectors, but also stationary engines consume maximum percentage of petroleum based fuels and have the evident benefit of a higher thermal efficiency than all other engines. However, the D. I. Diesel engine emits significant amount of pollutants suc...

Experiments were carried out to evaluate the performance of a medium grade LHR diesel engine consisting of air gap insulated piston with 3-mm air gap, with superni (an alloy of nickel) crown and air gap insulated liner with superni insert with different operating conditions of jatropha oil in crude from and biodiesel form with varied injection timing and injection pressure. Performance paramete...

This paper describes the method used in the design of a 26 million transistors chip at BULL to verify the timing performance using the hierarchical timing analysis tool HiTas as well as the interactive path browser Xtas. Those tools have been designed at UPMC and are now commercialized by AVERTEC. The complexity is handled by partitioning the analysis according to the hierarchical partitioning ...
