Estudo da indústria farmacêutica brasileira: a queda das patentes e entrada dos medicamentos genéricos

The objective of this study is to examine the pharmaceutical industry and changes that the fall of patents and entry of generics may cause in the price and consumption of drugs. Thus, there is a brief discussion about the global pharmaceutical industry, from its origins to the present day, showing in particular the case of the United States, today considered the largest industry in this sector. From this, the work seeks to address specifically the Brazilian industry and its regulation. Since the generic law implementation, the participation of this type of medicine has grown significantly in the country. Because they have always been lower than prices of their brand, the cost of treating disease is reduced, which makes generic drugs represent an improvement for consumers in terms of welfare of society

Incorporação do resíduo de cascalho de perfuração de poços de petróleo em formulações cerâmicas

During its operations, the oil industry generates a lot of waste, including gravel from drilling. Control of environmental impacts caused by this waste represents a major challenge. Such impacts can be minimized when it is given an appropriate management by being properly treated and properly disposed or recycled. The properties of these materials can be greatly influenced when a waste is added to its composition. This work aims to study the incorporation of gravel waste oil-well drilling in the standard body for production of red ceramic from a ceramic industry in São Gonçalo do Amarante / RN. The success of the incorporation can minimize costs in the production of ceramic pieces and reduce the environmental impacts caused by waste. The raw materials used were collected, characterized, and formulated with the percentages of 0%, 20% and 40% by weight of substitution of residue were synthesized at temperatures of 900, 1.010 and 1.120 °C using 30 minute firing intervals, 1 hour and 30min and 2 hours and 30 minutes, based on a factorial design 2³. Samples were then subjected to the tests of Water Absorption, Linear Retraction Firing, Flexural Rupture Strength, Apparent Porosity and Apparent Specific mass and Scanning Electron Microscopy (SEM) of break section. The results showed that the use of the residue for the manufacture of the ceramic products is possible (tiles, bricks and massive hollow bricks) replacing the clay to 40%, meeting the requirements of the standard and the literature for the technological properties of the final product.

Distribuição de derivados de petróleo por redes de polidutos: uma abordagem através de algoritmos evolucionários híbridos para um problema triobjetivo

An important problem faced by the oil industry is to distribute multiple oil products through pipelines. Distribution is done in a network composed of refineries (source nodes), storage parks (intermediate nodes), and terminals (demand nodes) interconnected by a set of pipelines transporting oil and derivatives between adjacent areas. Constraints related to storage limits, delivery time, sources availability, sending and receiving limits, among others, must be satisfied. Some researchers deal with this problem under a discrete viewpoint in which the flow in the network is seen as batches sending. Usually, there is no separation device between batches of different products and the losses due to interfaces may be significant. Minimizing delivery time is a typical objective adopted by engineers when scheduling products sending in pipeline networks. However, costs incurred due to losses in interfaces cannot be disregarded. The cost also depends on pumping expenses, which are mostly due to the electricity cost. Since industrial electricity tariff varies over the day, pumping at different time periods have different cost. This work presents an experimental investigation of computational methods designed to deal with the problem of distributing oil derivatives in networks considering three minimization objectives simultaneously: delivery time, losses due to interfaces and electricity cost. The problem is NP-hard and is addressed with hybrid evolutionary algorithms. Hybridizations are mainly focused on Transgenetic Algorithms and classical multi-objective evolutionary algorithm architectures such as MOEA/D, NSGA2 and SPEA2. Three architectures named MOTA/D, NSTA and SPETA are applied to the problem. An experimental study compares the algorithms on thirty test cases. To analyse the results obtained with the algorithms Pareto-compliant quality indicators are used and the significance of the results evaluated with non-parametric statistical tests.

Análise da biorremediação de compostos monoaromáticos em água através da pseudomonas aeruginosa

The monoaromatic compounds are toxic substances present in petroleum derivades and used broadly in the chemical and petrochemical industries. Those compounds are continuously released into the environment, contaminating the soil and water sources, leading to the possible unfeasibility of those hydrous resources due to their highly carcinogenic and mutagenic potentiality, since even in low concentrations, the BTEX may cause serious health issues. Therefore, it is extremely important to develop and search for new methodologies that assist and enable the treatment of BTEX-contaminated matrix. The bioremediation consists on the utilization of microbial groups capable of degrading hydrocarbons, promoting mineralization, or in other words, the permanent destruction of residues, eliminating the risks of future contaminations. This work investigated the biodegradation kinetics of water-soluble monoaromatic compounds (benzene, toluene and ethylbenzene), based on the evaluation of its consummation by the Pseudomonas aeruginosa bacteria, for concentrations varying from 40 to 200 mg/L. To do so, the performances of Monod kinetic model for microbial growth were evaluated and the material balance equations for a batch operation were discretized and numerically solved by the fourth order Runge-Kutta method. The kinetic parameters obtained using the method of least squares as statistical criteria were coherent when compared to those obtained from the literature. They also showed that, the microorganism has greater affinity for ethylbenzene. That way, it was possible to observe that Monod model can predict the experimental data for the individual biodegradation of the BTEX substrates and it can be applied to the optimization of the biodegradation processes of toxic compounds for different types of bioreactors and for different operational conditions.

Remoção de fenol de efluentes aquosos utilizando floculação iônica

Oil exploration is one of the most important industrial activities of modern society. Despite its derivatives present numerous applications in industrial processes, there are many undesirable by-products during this process, one of them is water separated from oil, called water production, it is constituted by pollutants difficult to degrade. In addition, the high volume of generated water makes its treatment a major problem for oil industries. Among the major contaminants of such effluents are phenol and its derivatives, substances of difficult natural degradation, which due their toxicity must be removed by a treatment process before its final disposal. In order to facilitate the removal of phenol in wastedwater from oil industry, it was developed an extraction system by ionic flocculation with surfactant. The ionic flocculation relies on the reaction of carboxylate surfactant and calcium íons, yielding in an insoluble surfactant that under stirring, aggregates forming floc capable of attracting the organic matter by adsorption. In this work was used base soap as ionic surfactant in the flocculation process and evaluated phenol removal efficiency in relation to the following parameters: surfactant concentration, phenol, calcium and electrolytes, stirring speed, contact time, temperature and pH. The flocculation of the surfactant occurred in the effluent (initial phenol concentration = 100 ppm) reaching 65% of phenol removal to concentrations of 1300 ppm and calcium of 1000 ppm, respectively, at T = 35 °C, pH = 9.7, stirring rate = 100 rpm and contact time of 5 minutes. The permanence of the flocs in an aqueous medium promotes desorption of the phenol from the flake surface to the solution, reaching 90% of desorption at a time of 150 minutes, and the study of desorption kinetics showed that Lagergren model of pseudo-first order was adequate to describe the phenol desorption. These results shows that the process may configure a new alternative of treatment in regard the removal of phenol of aqueous effluent of oil industry.

Ecogenômica de archaea e monitoramento de comunidades de procariotos redutores de sulfato: aplicações na indústria de petróleo e gás

The human activities responsible for the ambient degradation in the modern world are diverse. The industrial activities are preponderant in the question of the impact consequences for brazilian ecosystems. Amongst the human activities, the petroliferous industry in operation in Potiguar Petroliferous Basin (PPB) displays the constant risk of ambient impacts in the integrant cities, not only for the human populations and the environment, but also it reaches the native microorganisms of Caatinga ground and in the mangrove sediment. Not hindering, the elaboration of strategies of bioremediation for impacted areas pass through the knowledge of microbiota and its relations with the environment. Moreover, in the microorganism groups associated to oil, are emphasized the sulfate-reducing prokaryotes (SRP) that, in its anaerobic metabolism, these organisms participate of the sulfate reduction, discharging H2S, causing ambient risks and causing the corrosion of surfaces, as pipelines and tanks, resulting in damages for the industry. Some ancestries of PRS integrate the Archaea domain, group of microorganisms whose sequenced genomes present predominance of extremophilic adaptations, including surrounding with oil presence. This work has two correlated objectives: i) the detection and monitoring of the gene dsrB, gift in sulfate-reducing prokaryotes, through DGGE analysis in samples of mDNA of a mangrove sediment and semiarid soil, both in the BPP; ii) to relate genomic characteristics to the ecological aspects of Archaea through in silico studies, standing out the importance to the oil and gas industry. The results of the first work suggest that the petrodegraders communities of SRP persist after the contamination with oil in mangrove sediment and in semiarid soil. Comparing the populations of both sites, it reveals that there are variations in the size and composition during one year of experiments. In the second work, functional and structural factors are the probable cause to the pressure in maintenance of the conservation of the sequences in the multiple copies of the 16S rDNA gene. Is verified also the discrepancy established between total content GC and content GC of the same gene. Such results relating ribosomal genes and the ambient factors are important for metagenomic evaluations using PCR-DGGE. The knowledge of microbiota associated to the oil can contribute for a better destination of resources by the petroliferous industry and the development of bioremediation strategies. Likewise, search to lead to the best agreement of the performance of native microbiota in biogeochemical cycles in Potiguar Petroliferous Basin ecosystem

Farmácias homeopáticas : histórias da institucionalização de uma prática

O presente trabalho tem como objetivo principal analisar a institucionalização da prática farmacêutica homeopática nos seus 160 anos de existência no Brasil, a partir do surgimento das farmácias privadas e públicas, da estruturação do ensino desta prática e do arcabouço jurídico que a envolve. Para isso, buscou-se relatar a constituição do campo farmacêutico homeopático neste período e os ensaios desenvolvidos para a entrada da prática farmacêutica homeopática nos serviços básicos de saúde nas cidades de Niterói, Rio de Janeiro e Juiz de Fora, considerados como um estudo de caso de uma unidade social em observação. Para realização dos objetivos citados, utilizou-se das técnicas da observação participante e entrevistas para recolhimento da história" das farmácias e das dificuldades enfrentadas. Este trabalho coloca as farmácias homeopáticas como agentes dentro do campo homeopático que deste modo sofrem e exercem uma ação, fundamentalmente política, contribuindo para a institucionalização, em última análise, do sistema médico homeopático.

Sociedade Brasileira de Direito Aeronáutico (SBDA): a formulação da política aeronáutica brasileira (1950-1965)

Esta dissertação, ao tomar como objeto de pesquisa a Sociedade Brasileira de Direito Aeronáutico (SBDA), tendo por recorte cronológico os anos entre 1950 e 1965, pretende trazer para a análise histórica mais um elemento no auxílio à compreensão do processo de formação do Estado brasileiro no cerne de um projeto de desenvolvimento capitalista de matizes nacionalistas envolvendo infraestrutura, industrialização, ciência e tecnologia, inclusive a modernização das Forças Armadas, no qual a reorganização das incumbências das esferas pública e privada transpassada pela expansão tanto das atividades de regulamentação quanto dos órgãos e agências estatais conduziu a uma ampla institucionalização dos setores econômicos por parte do governo, no caso específico deste estudo o ramo Aeronáutico. A SBDA funcionou como articuladora de interesses entre a sociedade política (Ministério da Aeronáutica) e a sociedade civil (empresas e sindicatos), exercendo desta maneira no parelho estatal um papel que a insere na aplicação do conceito de Estado gramsciano. A formulação de um campo jurídico no Brasil, mediante a perspectiva de análise de Pierre Bourdieu relativa ao campo intelectual, integra a trajetória de luta da SBDA pela autonomia do Direito Aeronáutico, agindo como organizadora das demandas provenientes deste setor específico de atividades.
