The consideration of incorporation of Al in interstitial sites is reasonable, because the ionic radii for Al3+ and Zn2+ are 0.039 and 0.060, respectively, for tetrahedral coordination in the wurtzite structure of the ZnO [15].

Parallel sections of Pilot Program Section Theory Application English Vocabulary, grammar, written oral, sentence structures, question forming, instructions.
Parallel to this were the engineering requirement of developing a stronger general and specific vocabulary, written/oral English in active ways that integrated and generated ideas in technical areas (water, chemistry, biology and ecology etc).

Wood species, wood anatomic structure, and composition greatly affect the water absorption of timber.
The structure of wood is highly non-uniform.
This decreases the structure's overall strength [17].
It is observed that the weight of Beech and Oak is bigger due to the denser structure.

The technological importance of having a valid mathematical model of the hydroelectric process consists in the possibility to study the plant behavior for different working regimes using the results of the model simulation and consists, also, in the possibility of including the process in an automatic control structure.
Introduction The general structure of the hydroelectric plant is presented in Fig. 1.
Fig. 1 The structure of the hydroelectric plant.
Starting from the mathematical model structure from Eq. 1, the necessity of the identification of the three constants KTP, T1 and T2 of the process occurs.

Introduction The application of heat treatment allows creating the proper structure and properties of non-ferrous alloys.
As a result of supercooling and modification in Al-Si alloys, the structure of the original dendrite phase α was found [1-5].

XRD technique is used to explore the structure of crystals[22].
These four intensity peaks confirm the face-centered cubic (FCC) structure of AgNPs.
In FTIR spectroscopy, infrared radiations interact with the sample, and in this way, the sample's chemistry can be found by measuring the frequencies and intensities[25].
PL from Ag/MWCNTs might be caused by this shift in the energy band structure.
Crystallite size, AgNPs FCC structure, and AgNPs ornamentation on MWCNTs were all determined using XRD.
