O trabalho aborda a embalagem através de sua função de comunicação sob a perspectiva da comunicação integrada de marketing. Especificamente, aborda como a embalagem reproduz a mensagem da propaganda no ponto-de-venda detalhando, pelo objetivo geral de descrição, a análise e sistematização do processo de uso da embalagem como suporte de campanhas publicitárias expandindo o objetivo da comunicação integrada de marketing CIM. A metodologia consiste no método qualitativo com o procedimento de pesquisa descritiva aplicando as estratégias investigativas pesquisa bibliográfica, pesquisa documental e entrevista em profundidade que permitiram concluir que sob a perspectiva da comunicação integrada de marketing, a ampliação da função de comunicação da embalagem permite a reprodução da mensagem da propaganda no ponto de venda pelo estabelecimento da unificação de elementos entre as mensagens veiculadas na propaganda televisiva e embalagem.(AU)

Esta pesquisa tem como objetivo investigar e discutir a ambientação como elemento de comunicação aplicado ao ponto-de-venda livraria e observar e analisar como as atuais lojas se adaptaram a uma realidade de mercado, que visa envolver o cliente em uma experiência prazerosa, tendo em vista a concorrência do comércio virtual e a crescente venda de livros em supermercados. Pretende-se, neste trabalho, compreender a utilização dos diversos elementos sensoriais que envolvem: tato, olfato, paladar, visão e audição no ponto-de-venda físico. O objeto de estudo é a Livraria Cultura do Conjunto Nacional, sua relevância ocorre pelo fato da livraria ser a maior loja em metros quadrados do país. Por tratar-se de um fenômeno contemporâneo inserido no contexto da vida real, a metodologia utilizada é o Estudo de Caso Único e os procedimentos metodológicos são observação direta do consumidor no ponto-de-venda, pesquisa bibliográfica, entrevistas com freqüentadores da loja e com profissionais do setor. Pode-se concluir que as características hedônicas do consumidor contemporâneo que busca experiências prazerosas associada a sinergia da comunicação integrada de marketing favorecem para os resultados positivos apresentados pela livraria.(AU)

Produced water is a major problem associated with the crude oil extraction activity. The monitoring of the levels of metals in the waste is constant and requires the use of sensitive analytical techniques. However, the determination of trace elements can often require a pre-concentration step. The objective of this study was to develop a simple and rapid analytical method for the extraction and pre-concentration based on extraction phenomenon cloud point for the determination of Cd, Pb and Tl in produced water samples by spectrometry of high resolution Absorption source continues and atomization graphite furnace. The Box Behnken design was used to obtain the optimal condition of extraction of analytes. The factors were evaluated: concentration of complexing agent (o,o-dietilditilfosfato ammonium, DDTP), the concentration of hydrochloric acid and concentration of surfactant (Triton X -114). The optimal condition obtained through extraction was: 0,6% m v-1 DDTP, HCl 0,3 mol L-1 and 0,2% m v-1 of Triton X - 114 for Pb; 0,7% m v-1 DDTP, HCl 0,8 mol L-1 and 0,2% m v-1 Triton X-114 for Cd. For Tl was evidenced that best extraction condition occurs with no DDTP, the extraction conditions were HCl 1,0 mol L-1 e 1,0% m v-1 de Triton X - 114. The limits of detection for the proposed method were 0,005 µg L-1 , 0,03 µg L-1 and 0,09 µg L-1 to Cd, Pb and Tl, Respectively. Enrichment factors Were greater than 10 times. The method was applied to the water produced in the Potiguar basin, and addition and recovery tests were performed, and values were between 81% and 120%. The precision was expressed with relative standard deviation (RSD) is less than 5%

The textile sector is one of the main contributors to the generation of industrial wastewaters due to the use of large volumes of water, which has a high organic load content. In these, it is observed to the presence of dyes, surfactants, starch, alcohols, acetic acid and other constituents, from the various processing steps of the textiles. Hence, the treatment of textile wastewater becomes fundamental before releasing it into water bodies, where they can cause disastrous physical-chemical changes for the environment. Surfactants are substances widely used in separation processes and their use for treating textile wastewaters was evaluated in this research by applying the cloud point extraction and the ionic flocculation. In the cloud point extraction was used as surfactant nonylphenol with 9.5 ethoxylation degree to remove reactive dye. The process evaluation was performed in terms of temperature, surfactant and dye concentrations. The dye removal reached 91%. The ionic flocculation occurs due to the presence of calcium, which reacts with anionic surfactant to form insoluble surfactants capable of attracting the organic matter by adsorption. In this work the ionic flocculation using base soap was applied to the treatment of synthetic wastewater containing dyes belonging to three classes: direct, reactive, and disperse. It was evaluated by the influence of the following parameters: surfactant and electrolyte concentrations, stirring speed, equilibrium time, temperature, and pH. The flocculation of the surfactant was carried out in two ways: forming the floc in the effluent itself and forming the floc before mixing it to the effluent. Removal of reactive and direct dye, when the floc is formed into textile effluent was 97% and 87%, respectively. In the case where the floc is formed prior to adding it to the effluent, the removal to direct and disperse dye reached 92% and 87%, respectively. These results show the efficience of the evaluated processes for dye removal from textile wastewaters.

This research analyzes the actual Historic-Architectural Heritage of Assú City which is located in Rio Grande do Norte State, Brazil, the study is based on both Assú s residents perception and technician s viewpoint. It looks forward to expose this community s relationship with the existing number of historic buildings, the scale of people s identity to the place and the association of this perception toward the preservation and conservation s scale of the historic settlement. Since the contextualization of the degradation s process of central areas, the study draw nea initially the conceptual aspects, focusing on the debate about heritage and the preservationist practice. The work complements the discussion through an approach on people-environment relationship and environmental perception, considering relevant factors for planning process. The obtained and presented data had diagnosed the condition of the architectural pile and also allowed this work to formulate recommendations for the studied area and architectural set in order to contribute for future urban politics implementation that consider the building, which are not only important to the considered population, but to the Rio Grande do Norte s History, as well
