A região metropolitana do Rio de Janeiro passa por um processo de expansão industrial, principalmente nos municípios da borda oeste como Itaguaí, Seropédica e Rio de Janeiro (Zona Oeste), área com intensa emissão de material particulado inalável da atividade industrial. Além disso, a diversidade de seu sítio faz com a dispersão de poluentes seja ineficiente nesta área conhecida como Bacia Aérea I. Assim, este trabalho analisou os dados de material particulado inalável de estações de qualidade do ar do INEA, localizadas na Bacia Aérea I, entre 2009 e 2014 para avaliar o impacto na qualidade do ar pelo funcionamento da Companhia Siderúrgica do Atlântico (CSA), a partir de 2010. Os resultados mostraram que estações próximas ao distrito industrial de Santa Cruz registraram aumento nas concentrações de partículas inaláveis após o início das atividades CSA, com violações nos padrões de qualidade do ar estabelecidos na Resolução Conama nº3 (BRASIL, 1990), principalmente ao sul dos empreendimentos, devido à direção dos ventos predominantes. Desta maneira conclui-se que a população do bairro de Santa Cruz, nas proximidades da estação Largo do Bodegão, estao em situação de risco à saúde devido aos déficits sociais presentes na região, à presença dos empreendimentos que deterioram a qualidade do ar e a falta de informação que alerte a população sobre os riscos. Palavras-chave: Material particulado inalável, CSA, Saúde.   Abstract The metropolitan region of Rio de Janeiro goes through a process of industrial expansion, mainly in the municipalities of the western border such as Itaguaí, Seropédica and Rio de Janeiro (West Zone), an area with intense emission of inhalable particulate matter from industrial activity. In addition, the diversity of its site makes the dispersion of pollutants inefficient in this area known as the Air Basin I. Thus, this work analyzed the inhalable particulate data of INEA air quality stations, located in the Air Basin I, between 2009 and 2014 to evaluate the impact on air quality by the operation of Companhia Siderúrgica do Atlântico (CSA) from 2010. The results showed that stations near the industrial district of Santa Cruz registered an increase in the concentrations of inhalable particles after the beginning of CSA activities, with violations of air quality standards established in Conama Resolution No. 3 (BRAZIL, 1990), mainly to the south of the projects, due to the direction of prevailing winds. In this way it is concluded that the population of the neighborhood of Santa Cruz, near the station Largo do Bodegão, are in a situation of health risk due to the social deficits present in the region, to the presence of the enterprises that deteriorate the quality of the air and the lack information that alerts the population about the risks. Key words: Inhalable particulate matter, CSA, Health.

Perceived Quality clusters different aspects that influence the customer’s perception of non-functional quality on a product that are perceive through senses. All together those aspects and the harmony between them reflect the producer’s ability to control product parameters and thereby also mirror the functional quality of the product. High Perceived Quality cannot be added to the product at the end of the developing process. Project prerequisites, system solution, factory capability etc. are criterion to succeed. Therefore, it is important to be able to evaluate Perceived Quality early in the process when product system solutions and architecture are defined, although data maturity is low. This paper presents a comprehensive framework to manage and support evaluation of Perceived Quality aspects in a product development process. The framework is based on an industrial process in combination with recent research within the field. The framework focuses on activities that can be performed at different stages in the developing process based on maturity of the CAD or styling data. For example, if the styling data is divided into different components by split-lines it has reached higher level of maturity then styling data that not has been divided. Consequently, the choice of applied method is based on data maturity, regardless phase in the developing process. The framework contains methods based on several different simulation and analysis techniques. Design methods, Computer-Aided Tolerancing and FEA based non-rigid variation simulation are represented in the framework.

ABSTRACT We have observed that a soluble recombinant green fluorescent protein produced in Escherichia coli occurs in a wide conformational spectrum. This results in differently fluorescent protein fractions in which morphologically diverse soluble aggregates abound. Therefore, the functional quality of soluble versions of aggregation-prone recombinant proteins is defined statistically rather than by the prevalence of a canonical native structure.

The effect of plant biostimulation on fruits of traditional tomato germplasm is largely unknown. We examined how a tropical plant-derived biostimulant impacts the nutritional, functional, and compositional characteristics of tomato fruits from four landraces, collected in the San Marzano (SM) tomato Protected Designation of Origin (PDO) region, by profiling primary and secondary metabolites. Biostimulation was not able to completely reshuffle the morpho-physiological and nutritional profile of the four landraces. Their distinct phytochemical profile indicated a genotype-specific tuning of the analyzed traits, which also included an improved yield and fruit quality. Biostimulation of SM1 and SM3 increased photosynthetic accumulation of carbohydrate reserves, improved mineral nutrient use efficiency and consequently, yield (+21% and 34%, respectively). Moreover, biostimulation augmented the nutraceutical properties of the SM2 landrace. Interestingly, the plant-derived product increased in all genotypes lycopene, but not polyphenol accumulation in fruits. Our results show the potential of biostimulatory applications towards optimizing the fruit quality of the acclaimed SM landraces, which is suitable to satisfy both the rising consumer demand for premium traditional tomatoes and the technological needs of the food industry.

Abstract. We investigated the seasonal trends of OA sources affecting the air quality of Marseille (France) which is the largest harbor of the Mediterranean Sea. This was achieved by measurements of nebulized filter extracts using an aerosol mass spectrometer (offline-AMS). PM2.5 (particulate matter with an aerodynamic diameter
