Variable shift

A tribunal in Nova Scotia has recently held otherwise. In Michelin v Nova Scotia (Workers Compensation Board), a worker who was in perfect health and had no outside habits that would adversely affect his sleep complained that working variable shifts adversely affected his work and private life (54). The workers compensation tribunal found that shift-work-maladaption syndrome is a compensable injury under the workers compensation scheme. The board found the condition disabling because the worker was too tired to work safely, and his inability to adapt to the alternating shifts was the cause of the injury. The board also found persuasive the worker s clean and healthy lifestyle that did not otherwise affect his sleep. 

The plastic tube technique can also be used to mitigate the variable shift that occurs with liquid loss in the bubbler system when it is not refilled. In this case, simply move the pinch valve to the appropriate spot to rebalance the system.

DNA photolyases, which use the energy of blue light to split pyrimidine dimers formed by UV irradiation of DNA, provide other examples of large and variable shifts in the absorption spectmm of a bound chromophore. These enzymes contain a bound pterin (methylenetetrahydrofolate, MTHF) or deazaflavin, which serves to absorb light and transfer energy to a flavin radical in the active site [81]. The absorption maximum of MTHF occurs at 360 nm in solution, but ranges from 377 to 415 nm in the enzymes from different organisms [82].
