This research explores whether Environmental Management Accounting can be applied to assist an Australian cogeneration company in improving both its financial performance as well as its environmental performance. Cogeneration or ‘combined heat and power’, in this particular case, involves the simultaneous production of heat and electricity using a single fuel, that is, natural gas. The heat generated is then used to produce steam to meet the customers’ requirements as well as boost the production of electricity.

Ohmic currents induced prior to decoupling are investigated in a standard transport model accounting both for the expansion of the background geometry as well as of its relativistic inhomogeneities. The relative balance of the Ohmic electric fields in comparison with the Hall and thermoelectric contributions is specifically addressed. The impact of the Ohmic currents on the evolution of curvature perturbations is discussed numerically and it is shown to depend explicitly upon the evolution of the conductivity.

To achieve the objective, first, a post-tensioning anchorage system is equipped with arrays of ESGs (electrical strain gages) for measuring strain responses. The anchorage system is installed on the stressing system, which is used to resist prestress force from the anchorage. Second, strain responses of ESGs arrays are measured under series prestress loss cases. Third, strain variations are utilized to determine stress components sensitive to prestress force loss. Last, empirical equations for prestress loss estimation is proposed based on experimental strain data.
