Algerian Journal of Engineering and Technology <p>Algerian Journal of Engineering and Technology (AJET) is an international scholarly refereed research journal which aims to promote the theory and practice of technology, innovation, and engineering.</p> Faculty of Technology, University of Echahid Hamma Lakhdar, El-Oued, Algeria. en-US Algerian Journal of Engineering and Technology Study of corrosion inhibition performance of Glutaraldehyde on Aluminium in nitric acid solution <p style="text-align: justify;">The inhibition effect of glutaraldehyde on the corrosion behavior of aluminium in 1.4 M nitric acid solution was studied using weight loss method, adsorption studies and characterized instrumentally by Fourier Transform Infrared Spectroscopic (FT-IR) analysis. The effects of inhibitor concentration, temperature and surface coverage were all investigated. The effect of inhibitor concentration and other parameters were evaluated for different inhibitor concentrations and the probable mechanism for the studied inhibitor was also proposed. The results showed that glutaraldehyde possess an excellent inhibiting effect toward the corrosion of aluminium in nitric acid solution with highest inhibition efficiency of 84.68, 81.34 and 76.87 % at 308, 313 and 318 K in the presence of 0.1 M inhibitor concentration. The values of the activation energy, rate constant, half-life and rate constant in uninhibited acid solution were 31.84 kj mol-1, 3.9 k ×10-3 hr-1 and 1.76 × 102 hr which changed to 57.64 kj mol-1, 0.60 k ×10-3 hr-1 and 11.55 hr in the presence of 0.1 M inhibitor concentration. The positive values of enthalpy reflect the endothermic nature of the reaction. The negative values of entropy (ΔS) signified that the activated complex in the rate determining step represented an association, rather than dissociation. The adsorption of the inhibitor on the metal surface followed Langmuir adsorption isotherm.</p> <p style="text-align: justify;"><a href=""><img src="" alt="DOI"></a></p> <p><strong>Cite as: </strong>Husaini, M.,Usman, B.,Ibrahim, M.

This paper will develop an accurate mathematical model to simulate the faulty OeW-FPIM drives. The proposed model is based on the theory of electromagnetic coupling of electrical circuits coupled to the differential equation system governing the machine behavior in presence of the stator winding faults. In fact, when a short circuits between coils occurs, the stator winding function of the injured phase changes. As a consequence, the stator resistance, the stator inductance of this phase and its mutual inductance with all the other circuits change also. Consequently, the inductances and resistance matrices will be changed by taking into account the introduced coefficients of short-circuited turns. The performance of the OeW-FPIM drives have been tested via simulation under different fault scenarios conditions.</p> <p><a href=""><img src="" alt="DOI"></a></p> <p><strong>Cite as: </strong>Khadar, S.

Tensile test had been carried out on pre-corroded specimens, exposed to laboratory accelerated exfoliation corrosion solution. The analysis suggests that exfoliation exposure leads to decrease the mechanical properties of all materials. The effects of the grain boundary character distribution and precipitates on corrosion are discussed on the basis of experimental observations by Scanning Electron Microscope SEM combined with Energy Dispersive Spectroscopy EDS analysis. &nbsp;</p> <p style="text-align: justify;"><a href=""><img src="" alt="DOI"></a></p> <p style="text-align: justify;"><strong>Cite as: </strong>Brahami, A., Fajoui, J., Bouchouicha, B.

The metal (II) complexes were synthesized by refluxing the ethanolic solutions of the Schiff base and the chloride salts of the metals. Melting point, decomposition temperature, solubility, elemental analysis, fourier transform infrared spectroscopy, magnetic susceptibility and molar conductivity measurements were used to characterized the Schiff base and its metal complexes. The Schiff base was yellow and has a melting point of 251 OC. The decomposition temperature of the Cd (II) and Cu (II) complexes were 282 and 270 OC respectively. The elemental analysis of the complexes established the formation of 1:1 metal - ligand ratio. The non-electrolytic nature of the complexes were revealed by the molar conductivity values. The behavior of the Schiff base and its coordination with the metal ions was suggested by the infrared spectral data via the azomethine nitrogen and hydroxyl oxygen after deprotonation. The solubility test of the Schiff base its metal complexes was carried out by using different solvent. The antibacterial and antifungal activity were performed and discussed.</p> <p><a href=""><img src="" alt="DOI"></a></p> <p><strong>Cite as: </strong>Jabbi, A. M., Husaini, M., Aliyu, H. N. (2020).

The adsorption of hazardous malachite green (MG) from aqueous solution using activated carbon (DDAC) derived desert date seed shell was examined. Batch equilibrium technique was employed to study the effect of contact time (5-120 min), initial concentration (20-100 mg dm-3) and temperature (303-333 K) on the adsorption capacity of the prepared adsorbent. Experimental data were analyzed using five kinetic models: pseudo-first-order, pseudo-second-order, Elovich, intraparticle diffusion and Boyd models and it was found that the pseudo-second-order model fitted the adsorption data most with the highest correlation (R2 = 0.9999). The overall adsorption process appears to be jointly controlled by intraparticle diffusion and film diffusion mechanisms. Studies of thermodynamic behavior revealed a negative value for ∆G (-11.45 to 13.42 kJ mol-1), and a positive value for ∆H (8.39 kJ mol-1) and ∆S (0.065 kJ mol-1 K-1). These indicated the feasibility, endothermicity and spontaneity of the removal process. The results demonstrated that the adsorbent could be exploited in the removal of MG from aqueous solution.</p> <p style="text-align: justify;"><a href=""><img src="" alt="DOI"></a></p> <p style="text-align: justify;"><strong>Cite as:</strong></p> <p style="text-align: justify;">Yunusa, U.,Usman, B., Ibrahim M.
