Desempenho mecânico de embalagens rígidas utilizadas na indústria agroquímica: estudo de compressão

The world population is growing at exponential scales, thus the demand for food grows significantly. The use of pesticides is seen as a way to meet the demand for food and increase the efficiency and productivity of the agricultural sector. BASF SA in partnership with packaging suppliers represent a remarkable scene in the Brazilian market in the agrochemicals sector. In 2014, the Department of Agro from BASF Packaging, identified in its production process certain deformation of its rigid packaging during the filling process of pesticides. This phenomenon is probably caused by the low resistance to compression that the package is used. In order to eliminate the deformation of rigid packaging arising from the filling step, a study will be conducted in conjunction with the supplier JET UNIPAC whose on line problems occurred more frequently. The study is to identify the strength of the rigid containers standardize a compression resistance value at which the package is not deformed after the filling step. This study will present an investigation through experiments combined with theoretical concepts in order to determine possible causes for the emergence of this phenomenon. At the end of the study, a solution to eliminate or reduce to the maximum the packaging deformation problem appears

Análise de um trocador de calor tipo serpentina de uma planta de hipoclorito de sódio

This study aims to analyze the capacity of a helical coil heat exchanger to reach the requested heat transfer rates by a sodium hypochlorite production process. This heat exchanger was installed in an experimental way in order to reuse a source of low-temperatures water in such a way to become a more economical alternative than the existing cooling tower. Firstly, the concepts related to the theory of heat transfer applicable to the case were introduced. Then, the mapping of the main information about the production process and the technical specification of the current cooling system equipment's was realized. Using the dimensions of the heat exchanger installed today as reference, the calculations for determining the ideal length of the coil to different flows of hot fluid were performed. Finally, it was concluded that the heat exchanger currently employed does not provide heat transfer rates required for the maximum flow rate value supported by the cooling tower

Ceramic technology of the Asurini do Xingu, Brazil: An ethnoarchaeological study of artifact variability

This article presents some of the results of ethnoarchaeological research on ceramic technology I have conducted among the Asurini do Xingu, an Amazonian indigenous population inhabiting a village in the margins of the Xingu River, Para, Brazil. Based on collected data, presented throughout the article, I discuss the reasons behind the formal, quantitative, spatial and relational variability of the Asurini ceramic vessels. This work will demonstrate that these distinct dimensions of variability are related to the potters` technological choices during the vessels` production process, the ceramic teaching-learning structure, and the type, frequency, method and context of use of the same vessels. I try to make clear the different practical and symbolic aspects that may influence the production, use, reuse, storage and discard processes of the vessels. Furthermore, I compare the Asurini context with other ethnographic contexts and try to distinguish regularities that may serve as interpretative references to the study of archaeological ceramic assemblages.

Economia política da arte moderna II/ notas para uma sistematização provisória

Paradigma tradicional de excelência artesanal, com que meios pode a pintura responder à abstração do trabalho e à sua ordenação serial, inerentes à modernização capitalista? O texto presente busca sistematizar os momentos decisivos de um percurso que se estende de Manet (1832-1883) a Rothko (1903-1970). Constitui o capítulo conclusivo de uma investigação sobre a transformação crítica do modo de pintar em modo de fabricação, fundado na superação reflexiva da dicotomia entre trabalho intelectual e corporal, imposta historicamente à sociedade. Atualizada criticamente e assinalando um fecho possível do processo da arte moderna, a pintura de Rothko põe-se como a negação de todo aspecto individual da pintura e de unidade orgânica e monádica da obra. Alcança-se assim o último termo de um processo; termo que assinala o fim do ciclo da autonomia estética como forma ligada à liberdade do sujeito, idealizado como natureza desinteressada. Para o trabalho de resistência contra a aceleração da barbárie é fundamental doravante levar em conta os fatores de heteronomia supraindividuais que, se não logram controlar toda a produção, detêm a hegemonia na esfera da circulação.

A Bayesian nonparametric model for Taguchi's on-line quality monitoring procedure for attributes

A Bayesian nonparametric model for Taguchi's on-line quality monitoring procedure for attributes is introduced. The proposed model may accommodate the original single shift setting to the more realistic situation of gradual quality deterioration and allows the incorporation of an expert's opinion on the production process. Based on the number of inspections to be carried out until a defective item is found, the Bayesian operation for the distribution function that represents the increasing sequence of defective fractions during a cycle considering a mixture of Dirichlet processes as prior distribution is performed. Bayes estimates for relevant quantities are also obtained. (C) 2012 Elsevier B.V. All rights reserved.

Expression of recombinant human mutant granulocyte colony stimulating factor (Nartograstim) in Escherichia coli

The human granulocyte colony stimulating factor (hG-CSF) plays an important role in hematopoietic cell proliferation/differentiation and has been widely used as a therapeutic agent for treating neutropenias. Nartograstim is a commercial G-CSF that presents amino acid changes in specific positions when compared to the wildtype form, which potentially increase its activity and stability. The aim of this work was to develop an expression system in Escherichia coli that leads to the production of large amounts of a recombinant hG-CSF (rhG-CSF) biosimilar to Nartograstim. The nucleotide sequence of hg-csf was codon-optimized for expression in E. coli. As a result, high yields of the recombinant protein were obtained with adequate purity, structural integrity and biological activity. This protein has also been successfully used for the production of specific polyclonal antibodies in mice, which could be used in the control of the expression and purification in an industrial production process of this recombinant protein. These results will allow the planning of large-scale production of this mutant version of hG-CSF (Nartograstim), as a potential new biosimilar in the market.

Qualidade de sementes de soja colhidas de forma manual e mecânica com diferentes teores de água

A colheita é uma das principais etapas no processo de produção de sementes de soja. O momento adequado para se efetuar a colheita pode variar em função do tipo de colheita e do grau de umidade das sementes. Neste sentido, o objetivo dessa pesquisa foi determinar as alterações fisiológicas de sementes de soja colhidas de forma manual e mecânica com diferentes teores de água. Para tanto, utilizaram-se sementes das cultivares Embrapa 48 e FTS Águia, que têm diferenças no teor de lignina do tegumento, colhidas de forma manual e mecanicamente com 18,0; 15,0 e 12,0% de água. Após a colheita, as sementes foram submetidas à secagem, e a qualidade das sementes foi avaliada pelos testes de germinação, emergência de plântulas, tetrazólio (viabilidade e vigor), envelhecimento acelerado e índice de velocidade de emergência de plântula. Em seguida, as sementes foram armazenadas (20 °C e 45% UR do ar) e analisadas logo após a colheita e aos seis meses de armazenamento. Os resultados obtidos indicam que o parâmetro fisiológico das sementes de soja, não é afetado, quando: se realiza colheita manual com grau de umidade das sementes de 11,4% a 18,4%; e para sementes colhidas à máquina, com grau de umidade entre 12,0% a 15,9%; mantendo a qualidade fisiológica mesmo após seis meses de armazenamento.
