31. The medical documentation only has to say what work functions the employee is unable to do without accommodation. 32. Under this approach, each union is organized according to the craft, or specific work function , of its members. 33. Kelvin probe energy diagram at flat vacuum configuration, used for measuring work function difference between sample and probe. 34. They further described the necessary energetic requirements ( work functions ) for hole and electron injecting electrode contacts. 35. The difference of work function between the two conductors sets up an electric field in the organic layer. 36. Via the communication and collaboration management systems, users can communicate and collaborate in a group to perform work functions . 37. The dipole perturbs the potential at the surface leading, for example, to a change of the metal work function . 38. A useful result from characterization of solids by UPS is the determination of the work function of the material. 39. Only the Cold Regions Test Center ( CRTC ) and Public Works functions were to remain on the installation. 40. Many techniques have been developed based on different physical effects to measure the electronic work function of a sample.
