Al/Ni/Al and Ti/Ni/Al multi-layers were used to obtain p-type and ntype ohmic contacts after annealing at 1050 ºC in Ar.
The EL imaging was done using the setup described in [4].
Fig. 3 shows an EL image of forward biased diodes from the three samples along with the cofabricated commercial material.
EL imaging was used to correlate defects with device performance and reliability.

Fu et al. [1] indicated that the basin has a circumference of nearly 70 km and a size of 243 km2 above EL. +20m, only next to Taichung Basin.

No test was conducted to determine the Young’s modulus E, and therefore the triaxial compression tests and triaxial extension tests conducted by Kung et al. [2] on silty-clay of Taipei were studied to develop the normalized relationship between secant modulus and undrained shear strength for the clay of Taipei.
Wang et al. [3] pointed out that a number of previous tests conducted for Taipei Basin revealed that the normalized undrained initial stiffness modulus of clay was 500 when the strain was below 0.05%.
Looking at Ou et al. [8], the analysis results were close to the lower limit of the empirical value for Taipei Basin, which is δvmax /δhmax =0.5~1.0.

The exact meanings of elE� and irE� , in the context as thermodynamic parameters, have been explicitly defined by Wollants et al [4] as specific quantities over an infinitesimal step of the transformation at any given stage as opposed to global changes over the entire process of the transformation, i.e., they are functions of transformation fraction.
According to these definitions, transformation “equilibrium” conditions (critical temperatures or stresses) can be defined, at 0G� = , as: (0) (0) el ir s H E E M S � � � � � = � (4a) (1) (1) el ir f H E E M S � � � � � = � (4b) (0) (0) el ir f H E E A S � � � + � = � (4c) where the numerals in the parentheses indicate the transformation fractions.
Thus, the transformation interval and the thermal hysteresis can be determined as: ( (1) (0)) ( (1) (0)) M el el ir ir s f E E E E T M M S � � � + � � � � = � = � (5) 2 (0) (0) A M ir f s E A M S � � = � = � or 2 ( ) ( ) A M irE x x S � � = � (6) Eq. 5 states that transformation interval is determined by the differences in elE� and irE� between the start and the finish of the transformation process, instead of any given values of ( )elE x� and ( )irE x� .
The total energy exchange between the system and the ambient during the transformation is a cumulative quantity; thus it is computed as, for a unit quantity of material [6]: 0 0 0 ( ) ( ) x x el ir Hdx T Sdx E x dx E x dx = � � � � � � �

Zhang et al[10]. reported a WOLED with a maximum luminous efficiency of 9.22 cd/A and a maximum brightness of 8633 cd/m2 by using phosphor sensitized fluorescence.
Finally, a LiF buffer layer and Al cathode were vapor-deposited at a background pressure of 4×10- 4Pa onto the organic films.

The device has the maximum brightness of 31770 cd/m2 and the maximum EL efficiency of 11.63 cd/A.
Inset: Normalized EL spectrum of the device In summary, we have fabricated a WOLED based on phosphor sensitized fluorescence utilizing an efficient structure.

Wang et al. [20], proposed a parameter estimation method of the maximum likelihood of the DTM, and Hu et al.[21], established a non ideal DTM solved by a genetic algorithm.
The decision to study these systems is motivated by their high criticality, as indicated in Mahfoudet al [34].

Twenty crude oil-degrading bacterial strains were isolated from oil-contaminated sites at Al Hariga Oil Terminal and Nafoora Oilfield.
Our results are similar to those of Ismail et al. [13], who showed that Pseudomonas NBHCO4 strain is a biosurfactant producer that degrades 78% of crude oil in 28 d.
