The Hirst, Burkard seven-day and some impactors that rotate the agar-plate beneath an air-intake slit, have the added advantage of informing at what time of the day, certain spores were present in the air, which can be associated with various environmental (rain, wind, temperature or humidity effects) or operational variables (mechanical or human-mediated operations).
Like other companies that are struggling with growth, that problem may lie at the product level rather than the operational or mechanical level.
This chapter reviews safety, operational and mechanical aspects of helium relief system added to the Large Hadron Collider (LHC).
Last season, Lewis Hamilton and Jenson Button's title charge was derailed by a series of operational and mechanical issues, with the former choosing to quit the team he had been with since he was 14 for Mercedes.
Severe operating conditions such as a strong magnetic field, operational current and mechanical load, significant rate of field and current variation, nuclear heating and thermal load, impose specific requirements on the superconducting coil design.
The analytical performance of the smart bandage sensitivity, selectivity, operational stability, and mechanical robustness is described.
This immobilized biocatalyst was stable for more than 580 h without activity loss, significantly improving operational stability and mechanical properties over the conventional agarose matrix.
Advances in design and a better understanding of the factors that affect performance have helped to extend the operational life of mechanical seals.
The heat exchange through the building envelope, which determines its energy efficiency, is strongly influenced by several parameters along with the thermal characteristics of the building elements like the wall thermal resistance and heat capacity as well as the thermal time constant and operational conditions of mechanical equipment.
