In this study, BaTiO3 has been prepared from aqueous solution of barium acetate and titanium dioxide mixture. After drying, the barium titanate was obtained through solid state reaction. The thermal analysis TG-DTA and XRD techniques were used to study the formation of BaTiO3 and the mechanism of formation as well. The effects of powder activation, calcination temperature and time on the formation of barium titanate were studied. It was found that, the use of barium acetate retarded the formation of BaTiO3 and increased the temperature at which the reaction is completed. However, the coating process offered by this synthesis method for unmilled powder might be very useful in producing BaTiO3 powder having core shell morphology, where the BaTiO3 core is surrounded by a thin layer of Ba2TiO4 as a shell.

Keywords - Barium Titanate, Barium acetate, preparation and characterization.

To accomplish precise numerical simulation for transient problem in fluid machinery, a precise method was put forward—numerical simulation based on external performance results. Wherein rotational acceleration was taken into account and experimental results was taken as initial condition and boundary condition of numerical simulation, The merits of sliding mesh technique and dynamic mesh technique were fully applied respectively. The object is a low-specific-speed centrifugal pump, whose impeller is open and designed with straight blades.There is a clear head impact phenomenon. Additional head of model pump mainly comes from rotational acceleration and has nothing to do with flowing acceleration. The rise processes of flowrate and head evidently lag behind that of rotational speed..........

Keywords - Centrifugal pump; straight blades; starting; numerical simulation; fluid acceleration.

Emotional intelligence has become a very popular concept for psychological, educational and management researchers from the past years. Emotional Intelligence refers to a cluster of traits or abilities relating to the emotional side of life- abilities such as recognising and managing one's own emotions, being able to motivate oneself and restrain one's impulses, recognising and managing others' emotions and handling interpersonal relationships in an effective manner. The term emotional intelligence (EI) has its roots in the concept of Social Intelligence, as identified by Thorndike in 1920. Thorndike defines social intelligence as "the ability to understand and manage people - to act wisely in human relations." Psychologists have proposed a variety of definitions of emotional intelligence viz.

In this paper, we construct a deep learning network based on sparse autoencoder and optimal SVM classifier to diagnosis the gear fault conditions. The proposed spare autoencoder (SAE) is used to exploit the fused features of multi-source vibration data which is represented at the bottleneck of SAE (BtSAE). The fused features are then used to train and identify the gear fault condition. a new diagnosis technique for multi-level fault gear. This is a new approach method applied in diagnosing gear faults. The experimental results prove that the proposed method operates highly effective and mostly feasible for identifying gear faults in practice. By applying this method, the results will be more accurate and will shorten the time cost.

A Monte Carlo method for determining the intrinsic and extrinsic efficiencies detection of a CR-39 solid-state nuclear track detector (SSNTD) was developed. This method is based on the simulation of the trajectory of alpha particles with energy Ei emitted by the uranium and thorium series inside a natural material samples (for example phosphate), placed in a cylindrical capsule in contact with the SSNTD. The study of the convergence of the Monte Carlo approach shows that for 107 histories. The influence of the radius of the detector CR-39 and the cylindrical capsule on these efficiencies has been studied. The variation of these efficiencies as a function of the alpha particles initial energy Ei was also investigated. The impact of the critical angle θc of etching of the CR-39 SSNTD on these efficiencies was also been taken into consideration.

Groundnut shells were modified through functionalization and carbonization processes to produce three distinct GS-HCLC, GS-KOHC and GS-TPP adsorbents for adsorption of Pb (II) ions from aqueous solution. Adsorption studies was carried out under varying conditions of pH, contact time, adsorbent dosage, metal ion concentration and temperature after the results were documented. Batch adsorption experiments revealed that the highest adsorption capacities were observed at a pH of 11 and the adsorption process was dependent upon changes in contact time for all adsorbents. Adsorption capacity was observed to increase with increase in adsorbent dosage and decrease with increase in lead ion concentration across all adsorbents during the adsorption of Nickel ions from the aqueous medium.
