Marketing de relacionamento e relações públicas: uma aplicação no serviço de pós-venda da Embraer Executive Jets

The present study aims to investigate the interrelationship between the Relationship Marketing and Public Relations areas, high lighting its strategic value. The main goal is to discuss how the public relations professional can manage the customer loyalty by improving the after-sales services provided, applying it to a specific market such as business a viation. To establish the foundation to support the hypotheses, a revision of the subject literature was made, seeking to break down the barriers between marketing-mainly of relationship and public relations knowledge fields. A consult of the relevant literature was a continuous activity throughout the work. Divided into three chapters, the two first ones of fundamentals concepts, presents an after-sales services scenario, emphasizing the importance of the relationship and the definition of audiences in this area, in addition to a detailed description of the luxury market, a business aviation reality. The third chapter ends the discussion with a relationship proposal for Embraer Executive Jets, through actions based on the studied concepts. By gathering ideas and reflecting about the subject, using them to develop the proposal, a conclusion was resulted: the public relations professional is prepared and essential to build an effective after-sales relationship, since it's concerned about the communication excellence and knows the audiences significance in this process

Very Intense Distinct Blue and Red Photoluminescence Emission in MgTiO 3 Thin Films Prepared by the Polymeric Precursor Method: An Experimental and Theoretical Approach

MgTiO3 (MTO) thin films were prepared by the polymeric precursor method with posterior spin-coating deposition. The films were deposited on Pt(111)/Ti/SiO2/Si(100) substrates and heat treated at 350 °C for 2 h and then heat treated at 400, 450, 500, 550, 600, 650 and 700 °C for 2 h. The degree of structural order−disorder, optical properties, and morphology of the MTO thin films were investigated by X-ray diffraction (XRD), micro-Raman spectroscopy (MR), ultraviolet− visible (UV−vis) absorption spectroscopy, photoluminescence (PL) measurements, and field-emission gun scanning electron microscopy (FEG-SEM) to investigate the morphology. XRD revealed that an increase in the annealing temperature resulted in a structural organization of MTO thin films. First-principles quantum mechanical calculations based on density functional theory (B3LYP level) were employed to study the electronic structure of ordered and disordered asymmetric models. The electronic properties were analyzed, and the relevance of the present theoretical and experimental results was discussed in the light of PL behavior. The presence of localized electronic levels and a charge gradient in the band gap due to a break in the symmetry are responsible for the PL in disordered MTO lattice.

Bromofhenol blue discoloration using peroxidase immobilized on highly activated corncob powder

The aim of the present study was to evaluate the efficacy of peroxidase immobilized on corncob powder for the discoloration of dye. Peroxidase was extracted from soybean seed coat, followed by amination of the surface of the tertiary structure. The aminated peroxidase was immobilized on highly activated corncob powder and employed for the discoloration of bromophenol blue. Amination was performed with 10 or 50 mmol.L-1 carbodiimide and 1 mol.L-1 ethylenediamine. The amount of protein in the extract was 0.235 ± 0.011 mg.mL-1 and specific peroxidase activity was 86.06 ± 1.52 µmol min-1 . mg-1, using 1 mmol.L-1 ABTS as substrate. Ten mmol.L-1 and 50 mmol.L-1 aminated peroxidase retained 88 and 100% of the initial activity. Following covalent immobilization on a corncob powder-glyoxyl support, 10 and 50 mmol.L-1 aminated peroxidase retained 74 and 86% of activity, respectively. Derivatives were used for the discoloration of 0.02 mmol.L-1 bromophenol blue solution. After 30 min, 93 and 89% discoloration was achieved with the 10 mmol.L-1 and 50 mmol.L-1 derivatives, respectively. Moreover, these derivatives retained 60% of the catalytic properties when used three times. Peroxidase extracted from soybean seed coat immobilized on a low-cost corncob powder support exhibited improved thermal stability.
